As pre-requisites, you'll +need git and cmake installed. + +_See [dependencies.md](docs/dependencies.md) for more details regarding supported +versions of build tools._ + +```bash +# Check out the library. +$ git clone https://github.com/google/benchmark.git +# Go to the library root directory +$ cd benchmark +# Make a build directory to place the build output. +$ cmake -E make_directory "build" +# Generate build system files with cmake, and download any dependencies. +$ cmake -E chdir "build" cmake -DBENCHMARK_DOWNLOAD_DEPENDENCIES=on -DCMAKE_BUILD_TYPE=Release ../ +# or, starting with CMake 3.13, use a simpler form: +# cmake -DCMAKE_BUILD_TYPE=Release -S . -B "build" +# Build the library. +$ cmake --build "build" --config Release +``` +This builds the `benchmark` and `benchmark_main` libraries and tests. +On a unix system, the build directory should now look something like this: + +``` +/benchmark + /build + /src + /libbenchmark.a + /libbenchmark_main.a + /test + ... +``` + +Next, you can run the tests to check the build. + +```bash +$ cmake -E chdir "build" ctest --build-config Release +``` + +If you want to install the library globally, also run: + +``` +sudo cmake --build "build" --config Release --target install +``` + +Note that Google Benchmark requires Google Test to build and run the tests. This +dependency can be provided two ways: + +* Checkout the Google Test sources into `benchmark/googletest`. +* Otherwise, if `-DBENCHMARK_DOWNLOAD_DEPENDENCIES=ON` is specified during + configuration as above, the library will automatically download and build + any required dependencies. + +If you do not wish to build and run the tests, add `-DBENCHMARK_ENABLE_GTEST_TESTS=OFF` +to `CMAKE_ARGS`. + +### Debug vs Release + +By default, benchmark builds as a debug library. You will see a warning in the +output when this is the case. To build it as a release library instead, add +`-DCMAKE_BUILD_TYPE=Release` when generating the build system files, as shown +above. The use of `--config Release` in build commands is needed to properly +support multi-configuration tools (like Visual Studio for example) and can be +skipped for other build systems (like Makefile). + +To enable link-time optimisation, also add `-DBENCHMARK_ENABLE_LTO=true` when +generating the build system files. + +If you are using gcc, you might need to set `GCC_AR` and `GCC_RANLIB` cmake +cache variables, if autodetection fails. + +If you are using clang, you may need to set `LLVMAR_EXECUTABLE`, +`LLVMNM_EXECUTABLE` and `LLVMRANLIB_EXECUTABLE` cmake cache variables. + +To enable sanitizer checks (eg., `asan` and `tsan`), add: +``` + -DCMAKE_C_FLAGS="-g -O2 -fno-omit-frame-pointer -fsanitize=address -fsanitize=thread -fno-sanitize-recover=all" + -DCMAKE_CXX_FLAGS="-g -O2 -fno-omit-frame-pointer -fsanitize=address -fsanitize=thread -fno-sanitize-recover=all " +``` + +### Stable and Experimental Library Versions + +The main branch contains the latest stable version of the benchmarking library; +the API of which can be considered largely stable, with source breaking changes +being made only upon the release of a new major version. + +Newer, experimental, features are implemented and tested on the +[`v2` branch](https://github.com/google/benchmark/tree/v2). Users who wish +to use, test, and provide feedback on the new features are encouraged to try +this branch. However, this branch provides no stability guarantees and reserves +the right to change and break the API at any time. + +## Usage + +### Basic usage + +Define a function that executes the code to measure, register it as a benchmark +function using the `BENCHMARK` macro, and ensure an appropriate `main` function +is available: + +```c++ +#include + +static void BM_StringCreation(benchmark::State& state) { + for (auto _ : state) + std::string empty_string; +} +// Register the function as a benchmark +BENCHMARK(BM_StringCreation); + +// Define another benchmark +static void BM_StringCopy(benchmark::State& state) { + std::string x = "hello"; + for (auto _ : state) + std::string copy(x); +} +BENCHMARK(BM_StringCopy); + +BENCHMARK_MAIN(); +``` + +To run the benchmark, compile and link against the `benchmark` library +(libbenchmark.a/.so). If you followed the build steps above, this library will +be under the build directory you created. + +```bash +# Example on linux after running the build steps above. Assumes the +# `benchmark` and `build` directories are under the current directory. +$ g++ mybenchmark.cc -std=c++11 -isystem benchmark/include \ + -Lbenchmark/build/src -lbenchmark -lpthread -o mybenchmark +``` + +Alternatively, link against the `benchmark_main` library and remove +`BENCHMARK_MAIN();` above to get the same behavior. + +The compiled executable will run all benchmarks by default. Pass the `--help` +flag for option information or see the [User Guide](docs/user_guide.md). + +### Usage with CMake + +If using CMake, it is recommended to link against the project-provided +`benchmark::benchmark` and `benchmark::benchmark_main` targets using +`target_link_libraries`. +It is possible to use ```find_package``` to import an installed version of the +library. +```cmake +find_package(benchmark REQUIRED) +``` +Alternatively, ```add_subdirectory``` will incorporate the library directly in +to one's CMake project. +```cmake +add_subdirectory(benchmark) +``` +Either way, link to the library as follows. +```cmake +target_link_libraries(MyTarget benchmark::benchmark) +``` diff --git a/third_party/benchmark/WORKSPACE b/third_party/benchmark/WORKSPACE new file mode 100644 index 0000000..5032024 --- /dev/null +++ b/third_party/benchmark/WORKSPACE @@ -0,0 +1,24 @@ +workspace(name = "com_github_google_benchmark") + +load("//:bazel/benchmark_deps.bzl", "benchmark_deps") + +benchmark_deps() + +load("@rules_foreign_cc//foreign_cc:repositories.bzl", "rules_foreign_cc_dependencies") + +rules_foreign_cc_dependencies() + +load("@rules_python//python:repositories.bzl", "py_repositories") + +py_repositories() + +load("@rules_python//python:pip.bzl", "pip_parse") + +pip_parse( + name = "tools_pip_deps", + requirements_lock = "//tools:requirements.txt", +) + +load("@tools_pip_deps//:requirements.bzl", "install_deps") + +install_deps() diff --git a/third_party/benchmark/WORKSPACE.bzlmod b/third_party/benchmark/WORKSPACE.bzlmod new file mode 100644 index 0000000..9526376 --- /dev/null +++ b/third_party/benchmark/WORKSPACE.bzlmod @@ -0,0 +1,2 @@ +# This file marks the root of the Bazel workspace. +# See MODULE.bazel for dependencies and setup. diff --git a/third_party/benchmark/_config.yml b/third_party/benchmark/_config.yml new file mode 100644 index 0000000..1fa5ff8 --- /dev/null +++ b/third_party/benchmark/_config.yml @@ -0,0 +1,2 @@ +theme: jekyll-theme-midnight +markdown: GFM diff --git a/third_party/benchmark/appveyor.yml b/third_party/benchmark/appveyor.yml new file mode 100644 index 0000000..81da955 --- /dev/null +++ b/third_party/benchmark/appveyor.yml @@ -0,0 +1,50 @@ +version: '{build}' + +image: Visual Studio 2017 + +configuration: + -

This PR uses "read/write" for operations on the client side + and "send/receive" for the connection, e.g. server side. If this is + considered useful, we can revisit renaming of further methods in another + PR. + + Curl's protocol handler `readwrite()` method been changed: + + ```diff + - CURLcode (*readwrite)(struct Curl_easy *data, struct connectdata *conn, + - const char *buf, size_t blen, + - size_t *pconsumed, bool *readmore); + + CURLcode (*write_resp)(struct Curl_easy *data, const char *buf, size_t ble + n, + + bool is_eos, bool *done); + ``` + + The name was changed to clarify that this writes reponse data to the + client side. The parameter changes are: + + * `conn` removed as it always operates on `data->conn` + * `pconsumed` removed as the method needs to handle all data on success + * `readmore` removed as no longer necessary + * `is_eos` as indicator that this is the last call for the transfer + response (end-of-stream). + * `done` TRUE on return iff the transfer response is to be treated as + finished + + This change affects many files only because of updated comments in + handlers that provide no implementation. The real change is that the + HTTP protocol handlers now provide an implementation. + + The HTTP protocol handlers `write_resp()` implementation will get passed + **all** raw data of a server response for the transfer. The HTTP/1.x + formatted status and headers, as well as the undecoded response + body. `Curl_http_write_resp_hds()` is used internally to parse the + response headers and pass them on. This method is public as the RTSP + protocol handler also uses it. + + HTTP/1.1 "chunked" transport encoding is now part of the general + *content encoding* writer stack, just like other encodings. A new flag + `CLIENTWRITE_EOS` was added for the last client write. This allows + writers to verify that they are in a valid end state. The chunked + decoder will check if it indeed has seen the last chunk. + + The general response handling in `transfer.c:466` happens in function + `readwrite_data()`. This mainly operates now like: + + ``` + static CURLcode readwrite_data(data, ...) + { + do { + Curl_xfer_recv_resp(data, buf) + ... + Curl_xfer_write_resp(data, buf) + ... + } while(interested); + ... + } + ``` + + All the response data handling is implemented in + `Curl_xfer_write_resp()`. It calls the protocol handler's `write_resp()` + implementation if available, or does the default behaviour. + + All raw response data needs to pass through this function.

Libcurl implements an internal +conversion mechanism, but it has been designed for computers that have a +single native character set. OS/400 default native character set varies +depending on the country for which it has been localized. And more, a job +may dynamically alter its "native" character set. + Several characters that do not have fixed code in EBCDIC variants are +used in libcurl strings. As a consequence, using the existing conversion +mechanism would have lead in a localized binary library - not portable across +countries. + For this reason, and because libcurl was originally designed for ASCII based +operating systems, the current OS/400 implementation uses ASCII as internal +character set. This has been accomplished using the QADRT library and +include files, a C and system procedures ASCII wrapper library. See IBM QADRT +description for more information. + This then results in libcurl being an ASCII library: any function string +argument is taken/returned in ASCII and a C/C++ calling program built around +QADRT may use libcurl functions as on any other platform. + QADRT does not define ASCII wrappers for all C/system procedures: the +OS/400 configuration header file and an additional module (os400sys.c) define +some more of them, that are used by libcurl and that QADRT left out. + To support all the different variants of EBCDIC, non-standard wrapper +procedures have been added to libcurl on OS/400: they provide an additional +CCSID (numeric Coded Character Set ID specific to OS/400) parameter for each +string argument. Callback procedures arguments giving access to strings are +NOT converted, so text gathered this way is (probably !) ASCII. + + Another OS/400 problem comes from the fact that the last fixed argument of a +vararg procedure may not be of type char, unsigned char, short or unsigned +short. Enums that are internally implemented by the C compiler as one of these +types are also forbidden. Libcurl uses enums as vararg procedure tagfields... +Happily, there is a pragma forcing enums to type "int". The original libcurl +header files are thus altered during build process to use this pragma, in +order to force libcurl enums of being type int (the pragma disposition in use +before inclusion is restored before resuming the including unit compilation). + + Non-standard EBCDIC wrapper prototypes are defined in an additional header +file: ccsidcurl.h. These should be self-explanatory to an OS/400-aware +designer. CCSID 0 can be used to select the current job's CCSID. + Wrapper procedures with variable arguments are described below: + +_ curl_easy_setopt_ccsid() + Variable arguments are a string pointer and a CCSID (unsigned int) for +options: + CURLOPT_ABSTRACT_UNIX_SOCKET + CURLOPT_ACCEPT_ENCODING + CURLOPT_ALTSVC + CURLOPT_AWS_SIGV4 + CURLOPT_CAINFO + CURLOPT_CAPATH + CURLOPT_COOKIE + CURLOPT_COOKIEFILE + CURLOPT_COOKIEJAR + CURLOPT_COOKIELIST + CURLOPT_CRLFILE + CURLOPT_CUSTOMREQUEST + CURLOPT_DEFAULT_PROTOCOL + CURLOPT_DNS_INTERFACE + CURLOPT_DNS_LOCAL_IP4 + CURLOPT_DNS_LOCAL_IP6 + CURLOPT_DNS_SERVERS + CURLOPT_DOH_URL + CURLOPT_EGDSOCKET + CURLOPT_FTPPORT + CURLOPT_FTP_ACCOUNT + CURLOPT_FTP_ALTERNATIVE_TO_USER + CURLOPT_HAPROXY_CLIENT_IP + CURLOPT_HSTS + CURLOPT_INTERFACE + CURLOPT_ISSUERCERT + CURLOPT_KEYPASSWD + CURLOPT_KRBLEVEL + CURLOPT_LOGIN_OPTIONS + CURLOPT_MAIL_AUTH + CURLOPT_MAIL_FROM + CURLOPT_NETRC_FILE + CURLOPT_NOPROXY + CURLOPT_PASSWORD + CURLOPT_PINNEDPUBLICKEY + CURLOPT_PRE_PROXY + CURLOPT_PROTOCOLS_STR + CURLOPT_PROXY + CURLOPT_PROXYPASSWORD + CURLOPT_PROXYUSERNAME + CURLOPT_PROXYUSERPWD + CURLOPT_PROXY_CAINFO + CURLOPT_PROXY_CAPATH + CURLOPT_PROXY_CRLFILE + CURLOPT_PROXY_ISSUERCERT + CURLOPT_PROXY_KEYPASSWD + CURLOPT_PROXY_PINNEDPUBLICKEY + CURLOPT_PROXY_SERVICE_NAME + CURLOPT_PROXY_SSLCERT + CURLOPT_PROXY_SSLCERTTYPE + CURLOPT_PROXY_SSLKEY + CURLOPT_PROXY_SSLKEYTYPE + CURLOPT_PROXY_SSL_CIPHER_LIST + CURLOPT_PROXY_TLS13_CIPHERS + CURLOPT_PROXY_TLSAUTH_PASSWORD + CURLOPT_PROXY_TLSAUTH_TYPE + CURLOPT_PROXY_TLSAUTH_USERNAME + CURLOPT_RANDOM_FILE + CURLOPT_RANGE + CURLOPT_REDIR_PROTOCOLS_STR + CURLOPT_REFERER + CURLOPT_REQUEST_TARGET + CURLOPT_RTSP_SESSION_ID + CURLOPT_RTSP_STREAM_URI + CURLOPT_RTSP_TRANSPORT + CURLOPT_SASL_AUTHZID + CURLOPT_SERVICE_NAME + CURLOPT_SOCKS5_GSSAPI_SERVICE + CURLOPT_SSH_HOST_PUBLIC_KEY_MD5 + CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 + CURLOPT_SSH_KNOWNHOSTS + CURLOPT_SSH_PRIVATE_KEYFILE + CURLOPT_SSH_PUBLIC_KEYFILE + CURLOPT_SSLCERT + CURLOPT_SSLCERTTYPE + CURLOPT_SSLENGINE + CURLOPT_SSLKEY + CURLOPT_SSLKEYTYPE + CURLOPT_SSL_CIPHER_LIST + CURLOPT_SSL_EC_CURVES + CURLOPT_TLS13_CIPHERS + CURLOPT_TLSAUTH_PASSWORD + CURLOPT_TLSAUTH_TYPE + CURLOPT_TLSAUTH_USERNAME + CURLOPT_UNIX_SOCKET_PATH + CURLOPT_URL + CURLOPT_USERAGENT + CURLOPT_USERNAME + CURLOPT_USERPWD + CURLOPT_XOAUTH2_BEARER + All blob options are also supported. + In all other cases, it ignores the ccsid parameter and behaves as +curl_easy_setopt(). + Note that CURLOPT_ERRORBUFFER is not in the list above, since it gives the +address of an (empty) character buffer, not the address of a string. +CURLOPT_POSTFIELDS stores the address of static binary data (of type void *) +and thus is not converted. If CURLOPT_COPYPOSTFIELDS is issued after +CURLOPT_POSTFIELDSIZE != -1, the data size is adjusted according to the +CCSID conversion result length. + +_ curl_formadd_ccsid() + In the variable argument list, string pointers should be followed by a (long) +CCSID for the following options: + CURLFORM_BUFFER + CURLFORM_CONTENTTYPE + CURLFORM_COPYCONTENTS + CURLFORM_COPYNAME + CURLFORM_FILE + CURLFORM_FILECONTENT + CURLFORM_FILENAME + CURLFORM_PTRNAME + If taken from an argument array, an additional array entry must follow each +entry containing one of the above option. This additional entry holds the CCSID +in its value field, and the option field is meaningless. + It is not possible to have a string pointer and its CCSID across a function +parameter/array boundary. + Please note that CURLFORM_PTRCONTENTS and CURLFORM_BUFFERPTR are considered +unconvertible strings and thus are NOT followed by a CCSID. + +_ curl_easy_getinfo_ccsid() + The following options are followed by a 'char * *' and a CCSID. Unlike +curl_easy_getinfo(), the value returned in the pointer should be released with +curl_free() after use: + CURLINFO_CONTENT_TYPE + CURLINFO_EFFECTIVE_URL + CURLINFO_FTP_ENTRY_PATH + CURLINFO_LOCAL_IP + CURLINFO_PRIMARY_IP + CURLINFO_REDIRECT_URL + CURLINFO_REFERER + CURLINFO_RTSP_SESSION_ID + CURLINFO_SCHEME + Likewise, the following options are followed by a struct curl_slist * * and a +CCSID. + CURLINFO_COOKIELIST + CURLINFO_SSL_ENGINES +Lists returned should be released with curl_slist_free_all() after use. + Option CURLINFO_CERTINFO is followed by a struct curl_certinfo * * and a +CCSID. Returned structures should be freed with curl_certinfo_free_all() +after use. + Other options are processed like in curl_easy_getinfo(). + +_ curl_easy_strerror_ccsid(), curl_multi_strerror_ccsid(), +curl_share_strerror_ccsid() and curl_url_strerror_ccsid() work as their +non-ccsid version and return a string encoded in the additional ccsid +parameter. These strings belong to libcurl and may not be freed by the caller. +A subsequent call to the same procedure in the same thread invalidates the +previous result. + +_ curl_pushheader_bynum_cssid() and curl_pushheader_byname_ccsid() + Although the prototypes are self-explanatory, the returned string pointer +should be released with curl_free() after use, as opposite to the non-ccsid +versions of these procedures. + Please note that HTTP2 is not (yet) implemented on OS/400, thus these +functions will always return NULL. + +_ curl_easy_option_by_name_ccsid() returns a pointer to an untranslated option +metadata structure. As each curl_easyoption structure holds the option name in +ASCII, the curl_easy_option_get_name_ccsid() function allows getting it in any +supported ccsid. However the caller should release the returned pointer with +curl_free() after use. + +_ curl_easy_header_ccsid() works as its non-CCSID counterpart but requires an +additional ccsid parameter specifying the name parameter encoding. The output +hout parameter is kept in libcurl's encoding and should not be altered. + +_ curl_from_ccsid() and curl_to_ccsid() are string encoding conversion +functions between ASCII (latin1) and the given CCSID. The first parameter is +the source string, the second is the CCSID and the returned value is a pointer +to the dynamically allocated string. These functions do not impact on Curl's +behavior and are only provided for user convenience. After use, returned values +must be released with curl_free(). + + + Standard compilation environment does support neither autotools nor make; +in fact, very few common utilities are available. As a consequence, the +config-os400.h has been coded manually and the compilation scripts are +a set of shell scripts stored in subdirectory packages/OS400. + + The "curl" command and the test environment are currently not supported on +OS/400. + + +Protocols currently implemented on OS/400: +_ DICT +_ FILE +_ FTP +_ FTPS +_ FTP with secure transmission +_ GOPHER +_ HTTP +_ HTTPS +_ IMAP +_ IMAPS +_ IMAP with secure transmission +_ LDAP +_ POP3 +_ POP3S +_ POP3 with secure transmission +_ RTSP +_ SCP if libssh2 is enabled +_ SFTP if libssh2 is enabled +_ SMTP +_ SMTPS +_ SMTP with secure transmission +_ TELNET +_ TFTP + + + +Compiling on OS/400: + + These instructions targets people who knows about OS/400, compiling, IFS and +archive extraction.

If + another EBCDIC CCSID is required, it must be set via a locale through a call + to setlocale_a (QADRT's setlocale() ASCII wrapper) with category LC_ALL or + LC_CTYPE, or by setting environment variable QADRT_ENV_LOCALE to the locale + object path before executing the program. +_ Do not use original source include files unless you know what you are doing. + Use the installed members instead (in /QSYS.LIB/CURL.LIB/H.FILE and + /curl/include/curl). + + + +ILE/RPG support: + + Since most of the ILE OS/400 programmers use ILE/RPG exclusively, a +definition /INCLUDE member is provided for this language. To include all +libcurl definitions in an ILE/RPG module, line + + h bnddir('CURL/CURL') + +must figure in the program header, and line + + d/include curl/h,curl.inc + +in the global data section of the module's source code. + + No vararg procedure support exists in ILE/RPG: for this reason, the following +considerations apply: +_ Procedures curl_easy_setopt_long(), curl_easy_setopt_object(), + curl_easy_setopt_function(), curl_easy_setopt_offset() and + curl_easy_setopt_blob() are all alias prototypes to curl_easy_setopt(), but + with different parameter lists. +_ Procedures curl_easy_getinfo_string(), curl_easy_getinfo_long(), + curl_easy_getinfo_double(), curl_easy_getinfo_slist(), + curl_easy_getinfo_ptr(), curl_easy_getinfo_socket() and + curl_easy_getinfo_off_t() are all alias prototypes to curl_easy_getinfo(), + but with different parameter lists. +_ Procedures curl_multi_setopt_long(), curl_multi_setopt_object(), + curl_multi_setopt_function() and curl_multi_setopt_offset() are all alias + prototypes to curl_multi_setopt(), but with different parameter lists. +_ Procedures curl_share_setopt_int(), curl_share_setopt_ptr() and + curl_share_setopt_proc() are all alias prototypes to curl_share_setopt, + but with different parameter lists. +_ Procedure curl_easy_setopt_blob_ccsid() is an alias of + curl_easy_setopt_ccsid() supporting blob encoding conversion. +_ The prototype of procedure curl_formadd() allows specifying a pointer option + and the CURLFORM_END option. This makes possible to use an option array + without any additional definition. If some specific incompatible argument + list is used in the ILE/RPG program, the latter must define a specialised + alias. The same applies to curl_formadd_ccsid() too. +_ Since V7R4M0, procedure overloading is used to emulate limited "vararg-like" + definitions of curl_easy_setopt(), curl_multi_setopt(), curl_share_setopt() + and curl_easy_getinfo(). Blob and CCSID alternatives are NOT included in + overloading. + + Since RPG cannot cast a long to a pointer, procedure curl_form_long_value() +is provided for that purpose: this allows storing a long value in the +curl_forms array. Please note the form API is deprecated and the MIME API +should be used instead. + + +CLI tool: + + The build system provides it as a bound program, an IFS link to it and a +simple CL command. The latter however is not able to provide a different +parameter for each option since there are too many of those; instead, +parameters are entered in a single field subject to quoting and escaping, in +the same form as expected by the standard CLI program. + Care must be taken about the program output encoding: by default, it is sent +to the standard output and is thus subject to transcoding. It is therefore +recommended to use option "--output" to redirect output to a specific IFS file. +Similar problems may occur about the standard input encoding. diff --git a/third_party/curl/packages/OS400/ccsidcurl.c b/third_party/curl/packages/OS400/ccsidcurl.c new file mode 100644 index 0000000..60a10d7 --- /dev/null +++ b/third_party/curl/packages/OS400/ccsidcurl.c @@ -0,0 +1,1529 @@ +/*************************************************************************** + * _ _ ____ _ + * Project ___| | | | _ \| | + * / __| | | | |_) | | + * | (__| |_| | _ <| |___ + * \___|\___/|_| \_\_____| + * + * Copyright (C) Daniel Stenberg, , et al. + * + * This software is licensed as described in the file COPYING, which + * you should have received as part of this distribution.

It also requires the GNV Bash 4.2.45 kit as an update from the +same location or from the sourceforge.net GNV project. + +The HP C 7.x compiler was used for building the GNV version. + +The source kits are provided in backup savesets inside of the PCSI install kit. + +Backup save sets are currently the only distribution medium that I can be +sure is installed on a target VMS system that will correctly unpack files +with extended character sets in them.

A concealed logical name of +OLD_GNU: can be set up to reference the real GNV directory tree. + +Then a local copy of the GNU/GNV$GNU logical names can be set up as a search +list such as NEW_GNU:,OLD_GNU: + +The directory NEW_GNU:[usr] should be created. The make install phase should +create all the other directories. + +The make install process may abort if curl is already because it can not +uninstall the older version of curl because it does not have permission. + +The file stage_curl_install.com is used set up a new_gnu: directory tree +for testing. The PCSI kitting procedure uses these files as input. + +These files do not create the directories in the VMS_ROOT and LCL_ROOT +directory trees. You can create them with commands similar to: + + $ create/dir lcl_root:[curl]/prot=w:re + $ copy src_root:[curl...]*.dir - + lcl_root:[curl...]/prot=(o:rwed,w:re) + $ create/dir vms_root:[curl]/prot=w:re + $ copy src_root:[curl...]*.dir - + vms_root:[curl...]/prot=(o:rwed,w:re) + +One of the ways with to protect the source from being modified is to have +the directories under src_root: owned by a user or resource where the build +username only has read access to it. + + +Note to builders: + +GNV currently has a bug where configure scripts take a long time to run. +Some of the configure steps take a while to complete, and on a 600 Mhz +DS10 with IDE disks, taking an hour to run the CURL configure is normal. + +The following messages can be ignored and may get fixed in a future version +of GNV. The GNV$*.OPT files are used to find the libraries as many have +different names on VMS than on Unix. The Bash environment variable +GNV_CC_QUALIFIERS can override all other settings for the C Compiler. + +? cc: No support for switch -warnprotos +? cc: Unrecognized file toomanyargs +? cc: Warning: library "ssl" not found +? cc: Warning: library "crypto" not found +? cc: Warning: library "gssapi" not found +? cc: Warning: library "z" not found +u unimplemented switch - ignored + + +With these search lists set up and the properly, curl can be built by +setting your default to PRJ_ROOT:[curl.packages.vms] and then issuing +either the command: + + $ @pcsi_product_gnv_curl.com + +or + + $ @build_gnv_curl.com. + +The GNV configure procedure takes considerably longer than the DCL build +procedure takes. It is of use for testing the GNV build environment, and +may not have been kept up to date. + +The pcsi_product_gnv_curl.com needs the following logical names which +are described in the section below: + + gnv_pcsi_producer + gnv_pcsi_producer_full_name + stage_root + vms_root1 (Optional if vms_root is on a NFS volume) + src_root1 (Optional if src_root is on a NFS volume) + +The pcsi_product_gnv_curl.com is described in more detail below. It does +the following steps. The build steps are only done if they are needed to +allow using either DCL or GNV based building procedures. + + $ @build_vms list + + $ @gnv_link_curl.com + + $ @build_gnv_curl_release_notes.com + + $ @backup_gnv_curl_src.com + + $ @build_gnv_curl_pcsi_desc.com + + $ @build_gnv_curl_pcsi_text.com + + $ @stage_curl_install remove + $ @stage_curl_install + + Then builds the kit. + +The build_gnv_curl.com command procedure does the following: + + $ @setup_gnv_curl_build.com + + $ bash gnv_curl_configure.sh + + $ @clean_gnv_curl.com + + $ bash make_gnv_curl_install.sh + + $ @gnv_link_curl.com + + $ @stage_curl_install.com + + $ purge new_gnu:[*...]/log + +To clean up after a GNV based build to start over, the following commands are +used: + + $ bash + bash$ cd ../.. + bash$ make clean + bash$ exit + +Then run the @clean_gnv_curl.com.

If the symbols are longer than 32 characters, +then they will need to have the original be exact case CRC shortened and +an alias in upper case with CRC shortened, in addition to having an exact +case truncated alias and an uppercase truncated alias. + +The *.EXE files are not moved to the new_gnu: directory. + +After you are satisfied with the results of your build, you can move the +files from new_gnu: to old_gnu: at your convenience. + +Building a PCSI kit for an architecture takes the following steps after +making sure that you have a working build environment. + +Note that it requires manually creating two logical names as described +below. It is intentional that they be manually set. This is for +branding the PCSI kit based on who is making the kit. + + 1. Make sure that you have a staging directory that can be referenced + by the path STAGE_ROOT:[KIT] + + 2. Edit the file curl_release_note_start.txt or other text files to + reflect any changes. + + 3. Define the logical name GNV_PCSI_PRODUCER to indicate who is making + the distribution. For making updates to an existing open source + kit you may need to keep the producer the same. + + 4. Define the logical name GNV_PCSI_PRODUCER_FULL_NAME to be your full + name or full name of your company. + + 5. If you are producing an update kit, then update the file + vms_eco_level.h by changing the value for the VMS_ECO_LEVEL macro. + This file is currently only used in building the PCSI kit. + + 6. Edit the file PCSI_GNV_CURL_FILE_LIST.TXT if there are new files added + to the kit. These files should all be ODS-2 legal filenames and + directories. + + A limitation of the PCSI kitting procedure is that when selecting files, + it tends to ignore the directory structure and assumes that all files + with the same name are the same file, so every file placed in the kit + must have a unique name. Then a procedure needs to be added to the kit + to create an alias link on install and remove the link on remove. + + Since at this time curl does not need this alias procedure, the steps + to automatically build it are not included here. + + While newer versions of PCSI can support ODS-5 filenames, not all versions + of PCSI on systems that have ODS-5 filenames do. So as a post install + step, the PCSI kit built by these steps does a rename to the correct + case as a post install step. + + 7. Edit the build_curl_pcsi_desc.com and build_curl_pcsi_text.com if you + have changed the version of ZLIB that curl is built against. + + 8. Prepare to backup the files for building the kit. + + Note that if src_root: or vms_root: are NFS mounted disks, the + step of backing up the source files will probably hang or fail. + + You need to copy the source files to VMS mounted disks and create + logical names SRC_ROOT1 and VMS_ROOT1 to work around this to + reference local disks. Make sure src_root1:[000000] and + vms_root1:[000000] exist and can be written to. + + The command procedure compare_curl_source can be used to check + those directories and keep them up to date. + + @compare_curl_source.com SRCBCK UPDATE + + This compares the reference project source with the backup + staging directory for it and updates with any changes. + + @compare_curl_source.com VMSBCK UPDATE + + This compares the VMS specific source with the backup + staging directory for it and updates with any changes. + + Leave off "UPDATE" to just check without doing any changes. + + If you are not using NFS mounted disks and do not want to have a + separate directory for staging the sources for backup make sure + that src_root1: and vms_root1: do not exist. + + 9. Build the PCSI kit with @pcsi_product_gnv_curl.com + + The following message is normal: + %PCSI-I-CANNOTVAL, cannot validate + EAGLE$DQA0:[stage_root.][kit]VMSPORTS-AXPVMS-CURL-V0731-0-1.PCSI;1 + -PCSI-I-NOTSIGNED, product kit is not signed and therefore has + no manifest file + + This will result in an uncompressed kit for the target platform. + On Alpha and Integrity, the pcsi_product_gnv_curl.com can be used with + the "COMPRESSED" parameter to build both a compressed and uncompressed + kits. + +Good Luck. diff --git a/third_party/curl/packages/vms/curl_release_note_start.txt b/third_party/curl/packages/vms/curl_release_note_start.txt new file mode 100644 index 0000000..62b2836 --- /dev/null +++ b/third_party/curl/packages/vms/curl_release_note_start.txt @@ -0,0 +1,77 @@ +From file: CURL_RELEASE_NOTE_START.TXT + +Note: These kits are produced by a hobbyist and are providing any support +or any commitment to supply bug fixes or future releases.

Use the "REALCLEAN" option for +BUILD_VMS.COM and the "REALCLEAN" option for clean_gnv_curl.com. + +The (brute-force) DCL based builder is [.packages.vms]build_vms.com. +Comments in this procedure describe various optional parameters which +enable or disable optional program features, or which control the build +in other ways. Product files (.EXE, .H, .LIS, .MAP, .OBJ, .OLB, ...) +should be produced in an architecture-specific subdirectory under this +directory ([.ALPHA], [.IA64], [.VAX]). + +The file curl_gnv_build_steps.txt contains information on building using +the GNV tool kit, building a shared libcurl, and producing a PCSI kit for +distribution.

If you have built a curl with ZLIB and HPSSL support as well as if +LDAP and Kerberos installed, you can use the GNV_LINK_CURL.COM file. + +The GNV_LINK_CURL.COM contains information on how to link and run with a newer +version of HP SSL than what may be install on an Alpha or IA64 based system. + +To build the PCSI kit, follow the instructions in the file +curl_gnv_build_steps.txt. + +Other Notes: + +This release fixes known bugs #22, and #57 in the [curl.docs]known_bugs. +file. + +The libcurl formdata.c module and Curl tools post form now have some +understanding of VMS file types. Files will be posted in STREAM_LF format. + +The Curl tool now has some understanding of VMS file types and will upload the +files in STREAM_LF format. + +When CURL is uploading a VARIABLE format VMS file, it is less efficient as in +order to get the file size, it will first read the entire file once, and then +read the file again for the actual upload. + +The Curl tool will now always download files into STREAM_LF format. Even if a +file by that name with a different format already exists. This is needed to +allow interrupted downloads to be continued. + + +The libcurl file module still does not understand VMS file types and requires +the input files to be in STREAM_LF to work property. + +The test suites are not supported as of 7.11.0. + +The curlmsg.sdl and curlmsg.h files are generated from curlmsg.msg. +This is not done automatically, since the .MSG file is a hand edit +of the relevant stuff from the curl.h file.

Please run +"generate -help" for usage details. + +To generate project files for recent versions of Visual Studio instead, use +cmake. Refer to INSTALL-CMAKE in the docs directory. + +## Directory Structure + +The following directory structure is used for the legacy project files: + + somedirectory\ + |_curl + |_projects + |_ + |_ + |_lib + |_src + +This structure allows for side-by-side compilation of curl on the same machine +using different versions of a given compiler (for example VC10 and VC12) and +allows for your own application or product to be compiled against those +variants of libcurl for example. + +Note: Typically this side-by-side compilation is generally only required when +a library is being compiled against dynamic runtime libraries. + +## Dependencies + +The projects files also support build configurations that require third party +dependencies such as OpenSSL, wolfSSL and libssh2. If you wish to support +these, you will also need to download and compile those libraries as well. + +To support compilation of these libraries using different versions of +compilers, the following directory structure has been used for both the output +of curl and libcurl as well as these dependencies. + + somedirectory\ + |_curl + | |_ build + | |_ + | |_ + | |_ + | |_lib + | |_src + | + |_openssl + | |_ build + | |_ + | |_VC + | |_ + | + |_libssh2 + |_ build + |_ + |_VC + |_ + +As OpenSSL and wolfSSL don't support side-by-side compilation when using +different versions of Visual Studio, build helper batch files have been +provided to assist with this. Please run `build-openssl -help` and/or +`build-wolfssl -help` for usage details. + +## Building with Visual C++ + +To build with VC++, you will of course have to first install VC++ which is +part of Visual Studio. + +Once you have VC++ installed you should launch the application and open one of +the solution or workspace files. The VC directory names are based on the +version of Visual C++ that you will be using. Each version of Visual Studio +has a default version of Visual C++. We offer these versions: + + - VC10 (Visual Studio 2010 Version 10.0) + - VC11 (Visual Studio 2012 Version 11.0) + - VC12 (Visual Studio 2013 Version 12.0) + +Separate solutions are provided for both libcurl and the curl command line +tool as well as a solution that includes both projects. libcurl.sln, curl.sln +and curl-all.sln, respectively. We recommend using curl-all.sln to build both +projects. + +For example, if you are using Visual Studio 2010 then you should be able to +use `VC10\curl-all.sln` to build curl and libcurl. + +## Running DLL based configurations + +If you are a developer and plan to run the curl tool from Visual Studio with +any third-party libraries (such as OpenSSL, wolfSSL or LibSSH2) then you will +need to add the search path of these DLLs to the configuration's PATH +environment. To do that: + + 1. Open the 'curl-all.sln' or 'curl.sln' solutions + 2. Right-click on the 'curl' project and select Properties + 3. Navigate to 'Configuration Properties > Debugging > Environment' + 4. Add `PATH='Path to DLL';C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem` + +... where 'Path to DLL` is the configuration specific path. For example the +following configurations in Visual Studio 2010 might be: + +DLL Debug - DLL OpenSSL (Win32): + + PATH=..\..\..\..\..\openssl\build\Win32\VC10\DLL Debug;C:\Windows\system32; + C:\Windows;C:\Windows\System32\Wbem + +DLL Debug - DLL OpenSSL (x64): + + PATH=..\..\..\..\..\openssl\build\Win64\VC10\DLL Debug;C:\Windows\system32; + C:\Windows;C:\Windows\System32\Wbem + +DLL Debug - DLL wolfSSL (Win32): + + PATH=..\..\..\..\..\wolfssl\build\Win32\VC10\DLL Debug;C:\Windows\system32; + C:\Windows;C:\Windows\System32\Wbem + +DLL Debug - DLL wolfSSL (x64): + + PATH=..\..\..\..\..\wolfssl\build\Win64\VC10\DLL Debug;C:\Windows\system32; + C:\Windows;C:\Windows\System32\Wbem + +If you are using a configuration that uses multiple third-party library DLLs +(such as DLL Debug - DLL OpenSSL - DLL LibSSH2) then 'Path to DLL' will need +to contain the path to both of these. + +## Notes + +The following keywords have been used in the directory hierarchy: + + - `` - The platform (For example: Windows) + - `` - The IDE (For example: VC10) + - `` - The platform architecture (For example: Win32, Win64) + - `` - The target configuration (For example: DLL Debug, LIB + Release - LIB OpenSSL) + +Should you wish to help out with some of the items on the TODO list, or find +bugs in the project files that need correcting, and would like to submit +updated files back then please note that, whilst the solution files can be +edited directly, the templates for the project files (which are stored in the +git repository) will need to be modified rather than the generated project +files that Visual Studio uses. + +## Legacy Windows and SSL + +Some of the project configurations allow the use of Schannel, the native SSL +library in Windows which forms part of Windows SSPI. However, Schannel in +Windows <= XP is unable to connect to servers that no longer support the +legacy handshakes and algorithms used by those versions. If you will be using +curl in one of those earlier versions of Windows you should choose another SSL +backend such as OpenSSL. diff --git a/third_party/curl/projects/build-openssl.bat b/third_party/curl/projects/build-openssl.bat new file mode 100644 index 0000000..0ded764 --- /dev/null +++ b/third_party/curl/projects/build-openssl.bat @@ -0,0 +1,739 @@ +@echo off +rem *************************************************************************** +rem * _ _ ____ _ +rem * Project ___| | | | _ \| | +rem * / __| | | | |_) | | +rem * | (__| |_| | _ <| |___ +rem * \___|\___/|_| \_\_____| +rem * +rem * Copyright (C) Steve Holme, . +rem * +rem * This software is licensed as described in the file COPYING, which +rem * you should have received as part of this distribution.

If + `RTLIBCFG=static` then release builds use `/MT` and debug builds use `/MTd`. + +## Building your own application with libcurl (Visual Studio example) + + When you build curl and libcurl, nmake will show the relative path where the + output directory is. The output directory is named from the options nmake used + when building. You may also see temp directories of the same name but with + suffixes -obj-curl and -obj-lib. + + For example let's say you've built curl.exe and libcurl.dll from the Visual + Studio 2010 x64 Win64 Command Prompt: + + nmake /f Makefile.vc mode=dll VC=10 + + The output directory will have a name similar to + `..\builds\libcurl-vc10-x64-release-dll-ipv6-sspi-schannel`. + + The output directory contains subdirectories bin, lib and include. Those are + the directories to set in your Visual Studio project. You can either copy the + output directory to your project or leave it in place. Following the example, + let's assume you leave it in place and your curl top source directory is + `C:\curl-7.82.0`. You would set these options for configurations using the + x64 platform: + +~~~ + - Configuration Properties > Debugging > Environment + PATH=C:\curl-7.82.0\builds\libcurl-vc10-x64-release-dll-ipv6-sspi-schannel\bin;%PATH% + + - C/C++ > General > Additional Include Directories + C:\curl-7.82.0\builds\libcurl-vc10-x64-release-dll-ipv6-sspi-schannel\include; + + - Linker > General > Additional Library Directories + C:\curl-7.82.0\builds\libcurl-vc10-x64-release-dll-ipv6-sspi-schannel\lib; + + - Linker > Input > Additional Dependencies + libcurl.lib; +~~~ + + For configurations using the x86 platform (aka Win32 platform) you would + need to make a separate x86 build of libcurl. + + If you build libcurl static (`mode=static`) or debug (`DEBUG=yes`) then the + library name will vary and separate builds may be necessary for separate + configurations of your project within the same platform. This is discussed in + the next section. + +## Building your own application with a static libcurl + + When building an application that uses the static libcurl library on Windows, + you must define `CURL_STATICLIB`. Otherwise the linker will look for dynamic + import symbols. + + The static library name has an `_a` suffix in the basename and the debug + library name has a `_debug` suffix in the basename. For example, + `libcurl_a_debug.lib` is a static debug build of libcurl. + + You may need a separate build of libcurl for each VC configuration combination + (for example: Debug|Win32, Debug|x64, Release|Win32, Release|x64). + + You must specify any additional dependencies needed by your build of static + libcurl (for example: + `advapi32.lib;crypt32.lib;normaliz.lib;ws2_32.lib;wldap32.lib`). + +## Legacy Windows and SSL + + When you build curl using the build files in this directory the default SSL + backend will be Schannel (Windows SSPI), the native SSL library that comes + with the Windows OS. Schannel in Windows <= XP is not able to connect to + servers that no longer support the legacy handshakes and algorithms used by + those versions. If you will be using curl in one of those earlier versions of + Windows you should choose another SSL backend like OpenSSL. diff --git a/third_party/curl/winbuild/gen_resp_file.bat b/third_party/curl/winbuild/gen_resp_file.bat new file mode 100755 index 0000000..6286fd0 --- /dev/null +++ b/third_party/curl/winbuild/gen_resp_file.bat @@ -0,0 +1,34 @@ +@echo off +rem *************************************************************************** +rem * _ _ ____ _ +rem * Project ___| | | | _ \| | +rem * / __| | | | |_) | | +rem * | (__| |_| | _ <| |___ +rem * \___|\___/|_| \_\_____| +rem * +rem * Copyright (C) Daniel Stenberg, , et al. +rem * +rem * This software is licensed as described in the file COPYING, which +rem * you should have received as part of this distribution.

In particular this results in consistent + rounding on all platforms and removing the `s[n]printf` fallback for + decimal FP formatting. + +- Compile-time floating point formatting no longer requires the + header-only mode. For example + ([godbolt](https://godbolt.org/z/G37PTeG3b)): + + ```c++ + #include + #include + + consteval auto compile_time_dtoa(double value) -> std::array { + auto result = std::array(); + fmt::format_to(result.data(), FMT_COMPILE("{}"), value); + return result; + } + + constexpr auto answer = compile_time_dtoa(0.42); + ``` + + works with the default settings. + +- Improved the implementation of + [Dragonbox](https://github.com/jk-jeon/dragonbox), the algorithm + used for the default floating-point formatting + (https://github.com/fmtlib/fmt/pull/2713, + https://github.com/fmtlib/fmt/pull/2750). Thanks @jk-jeon. + +- Made `fmt::to_string` work with `__float128`. This uses the internal + FP formatter and works even on system without `__float128` support + in `[s]printf`. + +- Disabled automatic `std::ostream` insertion operator (`operator<<`) + discovery when `fmt/ostream.h` is included to prevent ODR + violations. You can get the old behavior by defining + `FMT_DEPRECATED_OSTREAM` but this will be removed in the next major + release. Use `fmt::streamed` or `fmt::ostream_formatter` to enable + formatting via `std::ostream` instead. + +- Added `fmt::ostream_formatter` that can be used to write `formatter` + specializations that perform formatting via `std::ostream`. For + example ([godbolt](https://godbolt.org/z/5sEc5qMsf)): + + ```c++ + #include + + struct date { + int year, month, day; + + friend std::ostream& operator<<(std::ostream& os, const date& d) { + return os << d.year << '-' << d.month << '-' << d.day; + } + }; + + template <> struct fmt::formatter : ostream_formatter {}; + + std::string s = fmt::format("The date is {}", date{2012, 12, 9}); + // s == "The date is 2012-12-9" + ``` + +- Added the `fmt::streamed` function that takes an object and formats + it via `std::ostream`. For example + ([godbolt](https://godbolt.org/z/5G3346G1f)): + + ```c++ + #include + #include + + int main() { + fmt::print("Current thread id: {}\n", + fmt::streamed(std::this_thread::get_id())); + } + ``` + + Note that `fmt/std.h` provides a `formatter` specialization for + `std::thread::id` so you don\'t need to format it via + `std::ostream`. + +- Deprecated implicit conversions of unscoped enums to integers for + consistency with scoped enums. + +- Added an argument-dependent lookup based `format_as` extension API + to simplify formatting of enums. + +- Added experimental `std::variant` formatting support + (https://github.com/fmtlib/fmt/pull/2941). For example + ([godbolt](https://godbolt.org/z/KG9z6cq68)): + + ```c++ + #include + #include + + int main() { + auto v = std::variant(42); + fmt::print("{}\n", v); + } + ``` + + prints: + + variant(42) + + Thanks @jehelset. + +- Added experimental `std::filesystem::path` formatting support + (https://github.com/fmtlib/fmt/issues/2865, + https://github.com/fmtlib/fmt/pull/2902, + https://github.com/fmtlib/fmt/issues/2917, + https://github.com/fmtlib/fmt/pull/2918).

Thanks @phprus. + +- Added support for ranges with `begin` / `end` found via the + argument-dependent lookup + (https://github.com/fmtlib/fmt/pull/2807). Thanks @rbrugo. + +- Fixed formatting of certain kinds of ranges of ranges + (https://github.com/fmtlib/fmt/pull/2787). Thanks @BRevzin. + +- Fixed handling of maps with element types other than `std::pair` + (https://github.com/fmtlib/fmt/pull/2944). Thanks @BrukerJWD. + +- Made tuple formatter enabled only if elements are formattable + (https://github.com/fmtlib/fmt/issues/2939, + https://github.com/fmtlib/fmt/pull/2940). Thanks @jehelset. + +- Made `fmt::join` compatible with format string compilation + (https://github.com/fmtlib/fmt/issues/2719, + https://github.com/fmtlib/fmt/pull/2720). Thanks @phprus. + +- Made compile-time checks work with named arguments of custom types + and `std::ostream` `print` overloads + (https://github.com/fmtlib/fmt/issues/2816, + https://github.com/fmtlib/fmt/issues/2817, + https://github.com/fmtlib/fmt/pull/2819). Thanks @timsong-cpp. + +- Removed `make_args_checked` because it is no longer needed for + compile-time checks + (https://github.com/fmtlib/fmt/pull/2760). Thanks @phprus. + +- Removed the following deprecated APIs: `_format`, `arg_join`, the + `format_to` overload that takes a memory buffer, `[v]fprintf` that + takes an `ostream`. + +- Removed the deprecated implicit conversion of `[const] signed char*` + and `[const] unsigned char*` to C strings. + +- Removed the deprecated `fmt/locale.h`. + +- Replaced the deprecated `fileno()` with `descriptor()` in + `buffered_file`. + +- Moved `to_string_view` to the `detail` namespace since it\'s an + implementation detail. + +- Made access mode of a created file consistent with `fopen` by + setting `S_IWGRP` and `S_IWOTH` + (https://github.com/fmtlib/fmt/pull/2733). Thanks @arogge. + +- Removed a redundant buffer resize when formatting to `std::ostream` + (https://github.com/fmtlib/fmt/issues/2842, + https://github.com/fmtlib/fmt/pull/2843).

Thanks @alexezeder. + +- Added initial support for compiling {fmt} as a C++20 module + (https://github.com/fmtlib/fmt/pull/2235, + https://github.com/fmtlib/fmt/pull/2240, + https://github.com/fmtlib/fmt/pull/2260, + https://github.com/fmtlib/fmt/pull/2282, + https://github.com/fmtlib/fmt/pull/2283, + https://github.com/fmtlib/fmt/pull/2288, + https://github.com/fmtlib/fmt/pull/2298, + https://github.com/fmtlib/fmt/pull/2306, + https://github.com/fmtlib/fmt/pull/2307, + https://github.com/fmtlib/fmt/pull/2309, + https://github.com/fmtlib/fmt/pull/2318, + https://github.com/fmtlib/fmt/pull/2324, + https://github.com/fmtlib/fmt/pull/2332, + https://github.com/fmtlib/fmt/pull/2340). Thanks @DanielaE. + +- Made symbols private by default reducing shared library size + (https://github.com/fmtlib/fmt/pull/2301). For example + there was a \~15% reported reduction on one platform. Thanks @sergiud. + +- Optimized includes making the result of preprocessing `fmt/format.h` + \~20% smaller with libstdc++/C++20 and slightly improving build + times (https://github.com/fmtlib/fmt/issues/1998). + +- Added support of ranges with non-const `begin` / `end` + (https://github.com/fmtlib/fmt/pull/1953). Thanks @kitegi. + +- Added support of `std::byte` and other formattable types to + `fmt::join` (https://github.com/fmtlib/fmt/issues/1981, + https://github.com/fmtlib/fmt/issues/2040, + https://github.com/fmtlib/fmt/pull/2050, + https://github.com/fmtlib/fmt/issues/2262). For example: + + ```c++ + #include + #include + #include + + int main() { + auto bytes = std::vector{std::byte(4), std::byte(2)}; + fmt::print("{}", fmt::join(bytes, "")); + } + ``` + + prints \"42\". + + Thanks @kamibo. + +- Implemented the default format for `std::chrono::system_clock` + (https://github.com/fmtlib/fmt/issues/2319, + https://github.com/fmtlib/fmt/pull/2345). For example: + + ```c++ + #include + + int main() { + fmt::print("{}", std::chrono::system_clock::now()); + } + ``` + + prints \"2021-06-18 15:22:00\" (the output depends on the current + date and time). Thanks @sunmy2019. + +- Made more chrono specifiers locale independent by default. Use the + `'L'` specifier to get localized formatting. For example: + + ```c++ + #include + + int main() { + std::locale::global(std::locale("ru_RU.UTF-8")); + auto monday = std::chrono::weekday(1); + fmt::print("{}\n", monday); // prints "Mon" + fmt::print("{:L}\n", monday); // prints "пн" + } + ``` + +- Improved locale handling in chrono formatting + (https://github.com/fmtlib/fmt/issues/2337, + https://github.com/fmtlib/fmt/pull/2349, + https://github.com/fmtlib/fmt/pull/2350). Thanks @phprus. + +- Deprecated `fmt/locale.h` moving the formatting functions that take + a locale to `fmt/format.h` (`char`) and `fmt/xchar` (other + overloads). This doesn\'t introduce a dependency on `` so + there is virtually no compile time effect. + +- Deprecated an undocumented `format_to` overload that takes + `basic_memory_buffer`. + +- Made parameter order in `vformat_to` consistent with `format_to` + (https://github.com/fmtlib/fmt/issues/2327). + +- Added support for time points with arbitrary durations + (https://github.com/fmtlib/fmt/issues/2208). For example: + + ```c++ + #include + + int main() { + using tp = std::chrono::time_point< + std::chrono::system_clock, std::chrono::seconds>; + fmt::print("{:%S}", tp(std::chrono::seconds(42))); + } + ``` + + prints \"42\". + +- Formatting floating-point numbers no longer produces trailing zeros + by default for consistency with `std::format`. For example: + + ```c++ + #include + + int main() { + fmt::print("{0:.3}", 1.1); + } + ``` + + prints \"1.1\". Use the `'#'` specifier to keep trailing zeros. + +- Dropped a limit on the number of elements in a range and replaced + `{}` with `[]` as range delimiters for consistency with Python\'s + `str.format`. + +- The `'L'` specifier for locale-specific numeric formatting can now + be combined with presentation specifiers as in `std::format`. For + example: + + ```c++ + #include + #include + + int main() { + std::locale::global(std::locale("fr_FR.UTF-8")); + fmt::print("{0:.2Lf}", 0.42); + } + ``` + + prints \"0,42\". The deprecated `'n'` specifier has been removed. + +- Made the `0` specifier ignored for infinity and NaN + (https://github.com/fmtlib/fmt/issues/2305, + https://github.com/fmtlib/fmt/pull/2310). Thanks @Liedtke. + +- Made the hexfloat formatting use the right alignment by default + (https://github.com/fmtlib/fmt/issues/2308, + https://github.com/fmtlib/fmt/pull/2317). Thanks @Liedtke. + +- Removed the deprecated numeric alignment (`'='`). Use the `'0'` + specifier instead. + +- Removed the deprecated `fmt/posix.h` header that has been replaced + with `fmt/os.h`. + +- Removed the deprecated `format_to_n_context`, `format_to_n_args` and + `make_format_to_n_args`. They have been replaced with + `format_context`, `` format_args` and ``make_format_args\`\` + respectively. + +- Moved `wchar_t`-specific functions and types to `fmt/xchar.h`. You + can define `FMT_DEPRECATED_INCLUDE_XCHAR` to automatically include + `fmt/xchar.h` from `fmt/format.h` but this will be disabled in the + next major release. + +- Fixed handling of the `'+'` specifier in localized formatting + (https://github.com/fmtlib/fmt/issues/2133). + +- Added support for the `'s'` format specifier that gives textual + representation of `bool` + (https://github.com/fmtlib/fmt/issues/2094, + https://github.com/fmtlib/fmt/pull/2109). For example: + + ```c++ + #include + + int main() { + fmt::print("{:s}", true); + } + ``` + + prints \"true\". Thanks @powercoderlol. + +- Made `fmt::ptr` work with function pointers + (https://github.com/fmtlib/fmt/pull/2131). For example: + + ```c++ + #include + + int main() { + fmt::print("My main: {}\n", fmt::ptr(main)); + } + ``` + + Thanks @mikecrowe. + +- The undocumented support for specializing `formatter` for pointer + types has been removed. + +- Fixed `fmt::formatted_size` with format string compilation + (https://github.com/fmtlib/fmt/pull/2141, + https://github.com/fmtlib/fmt/pull/2161). Thanks @alexezeder. + +- Fixed handling of empty format strings during format string + compilation (https://github.com/fmtlib/fmt/issues/2042): + + ```c++ + auto s = fmt::format(FMT_COMPILE("")); + ``` + + Thanks @alexezeder. + +- Fixed handling of enums in `fmt::to_string` + (https://github.com/fmtlib/fmt/issues/2036). + +- Improved width computation + (https://github.com/fmtlib/fmt/issues/2033, + https://github.com/fmtlib/fmt/issues/2091). For example: + + ```c++ + #include + + int main() { + fmt::print("{:-<10}{}\n", "你好", "世界"); + fmt::print("{:-<10}{}\n", "hello", "world"); + } + ``` + + prints + + ![](https://user-images.githubusercontent.com/576385/119840373-cea3ca80-beb9-11eb-91e0-54266c48e181.png) + + on a modern terminal. + +- The experimental fast output stream (`fmt::ostream`) is now + truncated by default for consistency with `fopen` + (https://github.com/fmtlib/fmt/issues/2018). For example: + + ```c++ + #include + + int main() { + fmt::ostream out1 = fmt::output_file("guide"); + out1.print("Zaphod"); + out1.close(); + fmt::ostream out2 = fmt::output_file("guide"); + out2.print("Ford"); + } + ``` + + writes \"Ford\" to the file \"guide\". To preserve the old file + content if any pass `fmt::file::WRONLY | fmt::file::CREATE` flags to + `fmt::output_file`. + +- Fixed moving of `fmt::ostream` that holds buffered data + (https://github.com/fmtlib/fmt/issues/2197, + https://github.com/fmtlib/fmt/pull/2198). Thanks @vtta. + +- Replaced the `fmt::system_error` exception with a function of the + same name that constructs `std::system_error` + (https://github.com/fmtlib/fmt/issues/2266). + +- Replaced the `fmt::windows_error` exception with a function of the + same name that constructs `std::system_error` with the category + returned by `fmt::system_category()` + (https://github.com/fmtlib/fmt/issues/2274, + https://github.com/fmtlib/fmt/pull/2275). The latter is + similar to `std::sytem_category` but correctly handles UTF-8. + Thanks @phprus. + +- Replaced `fmt::error_code` with `std::error_code` and made it + formattable (https://github.com/fmtlib/fmt/issues/2269, + https://github.com/fmtlib/fmt/pull/2270, + https://github.com/fmtlib/fmt/pull/2273). Thanks @phprus. + +- Added speech synthesis support + (https://github.com/fmtlib/fmt/pull/2206). + +- Made `format_to` work with a memory buffer that has a custom + allocator (https://github.com/fmtlib/fmt/pull/2300). + Thanks @voxmea. + +- Added `Allocator::max_size` support to `basic_memory_buffer`. + (https://github.com/fmtlib/fmt/pull/1960). Thanks @phprus. + +- Added wide string support to `fmt::join` + (https://github.com/fmtlib/fmt/pull/2236). Thanks @crbrz. + +- Made iterators passed to `formatter` specializations via a format + context satisfy C++20 `std::output_iterator` requirements + (https://github.com/fmtlib/fmt/issues/2156, + https://github.com/fmtlib/fmt/pull/2158, + https://github.com/fmtlib/fmt/issues/2195, + https://github.com/fmtlib/fmt/pull/2204).

Thanks @phprus. + +- Fixed writing to `stdout` when it is redirected to `NUL` on Windows + (https://github.com/fmtlib/fmt/issues/2080). + +- Fixed exception propagation from iterators + (https://github.com/fmtlib/fmt/issues/2097). + +- Improved `strftime` error handling + (https://github.com/fmtlib/fmt/issues/2238, + https://github.com/fmtlib/fmt/pull/2244). Thanks @yumeyao. + +- Stopped using deprecated GCC UDL template extension. + +- Added `fmt/args.h` to the install target + (https://github.com/fmtlib/fmt/issues/2096). + +- Error messages are now passed to assert when exceptions are disabled + (https://github.com/fmtlib/fmt/pull/2145). Thanks @NobodyXu. + +- Added the `FMT_MASTER_PROJECT` CMake option to control build and + install targets when {fmt} is included via `add_subdirectory` + (https://github.com/fmtlib/fmt/issues/2098, + https://github.com/fmtlib/fmt/pull/2100). + Thanks @randomizedthinking. + +- Improved build configuration + (https://github.com/fmtlib/fmt/pull/2026, + https://github.com/fmtlib/fmt/pull/2122). +

The new `MemoryWriter` class implements the default buffer + management with small allocations done on stack. So `fmt::Writer` + should be replaced with `fmt::MemoryWriter` in variable + declarations. + + Old code: + + ```c++ + fmt::Writer w; + ``` + + New code: + + ```c++ + fmt::MemoryWriter w; + ``` + + If you pass `fmt::Writer` by reference, you can continue to do so: + + ```c++ + void f(fmt::Writer &w); + ``` + + This doesn\'t affect the formatting API. + +- Support for custom memory allocators + (https://github.com/fmtlib/fmt/issues/69) + +- Formatting functions now accept [signed char]{.title-ref} and + [unsigned char]{.title-ref} strings as arguments + (https://github.com/fmtlib/fmt/issues/73): + + ```c++ + auto s = format("GLSL version: {}", glGetString(GL_VERSION)); + ``` + +- Reduced code bloat. According to the new [benchmark + results](https://github.com/fmtlib/fmt#compile-time-and-code-bloat), + cppformat is close to `printf` and by the order of magnitude better + than Boost Format in terms of compiled code size. + +- Improved appearance of the documentation on mobile by using the + [Sphinx Bootstrap + theme](http://ryan-roemer.github.io/sphinx-bootstrap-theme/): + + | Old | New | + | --- | --- | + | ![](https://cloud.githubusercontent.com/assets/576385/4792130/cd256436-5de3-11e4-9a62-c077d0c2b003.png) | ![](https://cloud.githubusercontent.com/assets/576385/4792131/cd29896c-5de3-11e4-8f59-cac952942bf0.png) | + +# 0.11.0 - 2014-08-21 + +- Safe printf implementation with a POSIX extension for positional + arguments: + + ```c++ + fmt::printf("Elapsed time: %.2f seconds", 1.23); + fmt::printf("%1$s, %3$d %2$s", weekday, month, day); + ``` + +- Arguments of `char` type can now be formatted as integers (Issue + https://github.com/fmtlib/fmt/issues/55): + + ```c++ + fmt::format("0x{0:02X}", 'a'); + ``` + +- Deprecated parts of the API removed. + +- The library is now built and tested on MinGW with Appveyor in + addition to existing test platforms Linux/GCC, OS X/Clang, + Windows/MSVC. + +# 0.10.0 - 2014-07-01 + +**Improved API** + +- All formatting methods are now implemented as variadic functions + instead of using `operator<<` for feeding arbitrary arguments into a + temporary formatter object. This works both with C++11 where + variadic templates are used and with older standards where variadic + functions are emulated by providing lightweight wrapper functions + defined with the `FMT_VARIADIC` macro. You can use this macro for + defining your own portable variadic functions: + + ```c++ + void report_error(const char *format, const fmt::ArgList &args) { + fmt::print("Error: {}"); + fmt::print(format, args); + } + FMT_VARIADIC(void, report_error, const char *) + + report_error("file not found: {}", path); + ``` + + Apart from a more natural syntax, this also improves performance as + there is no need to construct temporary formatter objects and + control arguments\' lifetimes. Because the wrapper functions are + very lightweight, this doesn\'t cause code bloat even in pre-C++11 + mode. + +- Simplified common case of formatting an `std::string`. Now it + requires a single function call: + + ```c++ + std::string s = format("The answer is {}.", 42); + ``` + + Previously it required 2 function calls: + + ```c++ + std::string s = str(Format("The answer is {}.") << 42); + ``` + + Instead of unsafe `c_str` function, `fmt::Writer` should be used + directly to bypass creation of `std::string`: + + ```c++ + fmt::Writer w; + w.write("The answer is {}.", 42); + w.c_str(); // returns a C string + ``` + + This doesn\'t do dynamic memory allocation for small strings and is + less error prone as the lifetime of the string is the same as for + `std::string::c_str` which is well understood (hopefully). + +- Improved consistency in naming functions that are a part of the + public API. Now all public functions are lowercase following the + standard library conventions. Previously it was a combination of + lowercase and CapitalizedWords. Issue + https://github.com/fmtlib/fmt/issues/50. + +- Old functions are marked as deprecated and will be removed in the + next release. + +**Other Changes** + +- Experimental support for printf format specifications (work in + progress): + + ```c++ + fmt::printf("The answer is %d.", 42); + std::string s = fmt::sprintf("Look, a %s!", "string"); + ``` + +- Support for hexadecimal floating point format specifiers `a` and + `A`: + + ```c++ + print("{:a}", -42.0); // Prints -0x1.5p+5 + print("{:A}", -42.0); // Prints -0X1.5P+5 + ``` + +- CMake option `FMT_SHARED` that specifies whether to build format as + a shared library (off by default). + +# 0.9.0 - 2014-05-13 + +- More efficient implementation of variadic formatting functions. + +- `Writer::Format` now has a variadic overload: + + ```c++ + Writer out; + out.Format("Look, I'm {}!", "variadic"); + ``` + +- For efficiency and consistency with other overloads, variadic + overload of the `Format` function now returns `Writer` instead of + `std::string`. Use the `str` function to convert it to + `std::string`: + + ```c++ + std::string s = str(Format("Look, I'm {}!", "variadic")); + ``` + +- Replaced formatter actions with output sinks: `NoAction` -\> + `NullSink`, `Write` -\> `FileSink`, `ColorWriter` -\> + `ANSITerminalSink`. This improves naming consistency and shouldn\'t + affect client code unless these classes are used directly which + should be rarely needed. + +- Added `ThrowSystemError` function that formats a message and throws + `SystemError` containing the formatted message and system-specific + error description.

+ +There are plenty of methods for doing this task, from standard ones like +the printf family of function and iostreams to Boost Format and +FastFormat libraries. The reason for creating a new library is that +every existing solution that I found either had serious issues or +didn\'t provide all the features I needed. + +## printf + +The good thing about `printf` is that it is pretty fast and readily +available being a part of the C standard library. The main drawback is +that it doesn\'t support user-defined types. `printf` also has safety +issues although they are somewhat mitigated with [\_\_attribute\_\_ +((format (printf, +\...))](https://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html) in +GCC. There is a POSIX extension that adds positional arguments required +for +[i18n](https://en.wikipedia.org/wiki/Internationalization_and_localization) +to `printf` but it is not a part of C99 and may not be available on some +platforms. + +## iostreams + +The main issue with iostreams is best illustrated with an example: + +``` c++ +std::cout << std::setprecision(2) << std::fixed << 1.23456 << "\n"; +``` + +which is a lot of typing compared to printf: + +``` c++ +printf("%.2f\n", 1.23456); +``` + +Matthew Wilson, the author of FastFormat, called this \"chevron hell\". +iostreams don\'t support positional arguments by design. + +The good part is that iostreams support user-defined types and are safe +although error handling is awkward. + +## Boost Format + +This is a very powerful library that supports both `printf`-like format +strings and positional arguments. Its main drawback is performance. +According to various benchmarks, it is much slower than other methods +considered here. Boost Format also has excessive build times and severe +code bloat issues (see [Benchmarks](#benchmarks)). + +## FastFormat + +This is an interesting library that is fast, safe, and has positional +arguments. However, it has significant limitations, citing its author: + +> Three features that have no hope of being accommodated within the +> current design are: +> +> - Leading zeros (or any other non-space padding) +> - Octal/hexadecimal encoding +> - Runtime width/alignment specification + +It is also quite big and has a heavy dependency, STLSoft, which might be +too restrictive for using it in some projects. + +## Boost Spirit.Karma + +This is not a formatting library but I decided to include it here for +completeness. As iostreams, it suffers from the problem of mixing +verbatim text with arguments. The library is pretty fast, but slower on +integer formatting than `fmt::format_to` with format string compilation +on Karma\'s own benchmark, see [Converting a hundred million integers to +strings per +second](http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html). + +# License + +{fmt} is distributed under the MIT +[license](https://github.com/fmtlib/fmt/blob/master/LICENSE). + +# Documentation License + +The [Format String Syntax](https://fmt.dev/latest/syntax.html) section +in the documentation is based on the one from Python [string module +documentation](https://docs.python.org/3/library/string.html#module-string). +For this reason, the documentation is distributed under the Python +Software Foundation license available in +[doc/python-license.txt](https://raw.github.com/fmtlib/fmt/master/doc/python-license.txt). +It only applies if you distribute the documentation of {fmt}. + +# Maintainers + +The {fmt} library is maintained by Victor Zverovich +([vitaut](https://github.com/vitaut)) with contributions from many other +people.

By default, GFLAGS_IS_SUBPROJECT is set to TRUE when the +# CMAKE_SOURCE_DIR is not identical to the directory of this CMakeLists.txt +# file, i.e., the top-level directory of the gflags project source tree. +# +# When this project is a subproject (GFLAGS_IS_SUBPROJECT is TRUE), the default +# settings are such that only the static single-threaded library is built +# without installation of the gflags files. The "gflags::gflags" target is in +# this case an ALIAS library target for the "gflags_nothreads_static" library +# target. Targets which depend on the gflags library should link to the +# "gflags::gflags" library target. +# +# Example CMakeLists.txt of user project which requires separate gflags +# installation: cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR) +# +# project(Foo) +# +# find_package(gflags REQUIRED) +# +# add_executable(foo src/foo.cc) target_link_libraries(foo gflags::gflags) +# +# Example CMakeLists.txt of user project which requires separate single-threaded +# static gflags installation: cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR) +# +# project(Foo) +# +# find_package(gflags COMPONENTS nothreads_static) +# +# add_executable(foo src/foo.cc) target_link_libraries(foo gflags::gflags) +# +# Example CMakeLists.txt of super-project which contains gflags source tree: +# cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR) +# +# project(Foo) +# +# add_subdirectory(gflags) +# +# add_executable(foo src/foo.cc) target_link_libraries(foo gflags::gflags) +# +# Variables to configure the source files: - GFLAGS_IS_A_DLL - GFLAGS_NAMESPACE +# - GFLAGS_ATTRIBUTE_UNUSED - GFLAGS_INTTYPES_FORMAT +# +# Variables to configure the build: - GFLAGS_SOVERSION - +# GFLAGS_BUILD_SHARED_LIBS - GFLAGS_BUILD_STATIC_LIBS - GFLAGS_BUILD_gflags_LIB +# - GFLAGS_BUILD_gflags_nothreads_LIB - GFLAGS_BUILD_TESTING - +# GFLAGS_BUILD_PACKAGING +# +# Variables to configure the installation: - GFLAGS_INCLUDE_DIR - +# GFLAGS_LIBRARY_INSTALL_DIR or LIB_INSTALL_DIR or LIB_SUFFIX - +# GFLAGS_INSTALL_HEADERS - GFLAGS_INSTALL_SHARED_LIBS - +# GFLAGS_INSTALL_STATIC_LIBS + +cmake_minimum_required(VERSION 3.0.2 FATAL_ERROR) + +if(POLICY CMP0042) + cmake_policy(SET CMP0042 NEW) +endif() + +if(POLICY CMP0048) + cmake_policy(SET CMP0048 NEW) +endif() + +# ---------------------------------------------------------------------------- +# includes +include("${CMAKE_CURRENT_SOURCE_DIR}/cmake/utils.cmake") + +# ---------------------------------------------------------------------------- +# package information +set(PACKAGE_NAME "gflags") +set(PACKAGE_VERSION "2.2.2") +set(PACKAGE_STRING "${PACKAGE_NAME} ${PACKAGE_VERSION}") +set(PACKAGE_TARNAME "${PACKAGE_NAME}-${PACKAGE_VERSION}") +set(PACKAGE_BUGREPORT "https://github.com/gflags/gflags/issues") +set(PACKAGE_DESCRIPTION + "A commandline flags library that allows for distributed flags.") +set(PACKAGE_URL "http://gflags.github.io/gflags") + +project( + ${PACKAGE_NAME} + VERSION ${PACKAGE_VERSION} + LANGUAGES CXX) +if(CMAKE_VERSION VERSION_LESS 3.4) + # C language still needed because the following required CMake modules (or + # their dependencies, respectively) are not correctly handling the case where + # only CXX is enabled - CheckTypeSize.cmake (fixed in CMake 3.1, cf. + # https://cmake.org/Bug/view.php?id=14056) - FindThreads.cmake (fixed in + # CMake 3.4, cf. https://cmake.org/Bug/view.php?id=14905) + enable_language(C) +endif() + +version_numbers(${PACKAGE_VERSION} PACKAGE_VERSION_MAJOR PACKAGE_VERSION_MINOR + PACKAGE_VERSION_PATCH) + +# shared library ABI version number, can be overridden by package maintainers +# using -DGFLAGS_SOVERSION=XXX on the command-line +if(GFLAGS_SOVERSION) + set(PACKAGE_SOVERSION "${GFLAGS_SOVERSION}") +else() + # TODO: Change default SOVERSION back to PACKAGE_VERSION_MAJOR with the next + # increase of major version number (i.e., 3.0.0 -> SOVERSION 3) The + # .

In particular, +it restores binary ABI compatibility with release version 2.0. +The deprecated "google" namespace is by default still kept as +primary namespace while symbols are imported into the new "gflags" namespace. +This can be overridden using the CMake variable GFLAGS_NAMESPACE. + +Other fixes of the build configuration are related to the (patched) +CMake modules FindThreads.cmake and CheckTypeSize.cmake. These have +been removed and instead the C language is enabled again even though +gflags is written in C++ only. + +This release also marks the complete move of the gflags project +from Google Code to GitHub. Email addresses of original issue +reporters got lost in the process. Given the age of most issue reports, +this should be negligable. + +Please report any further issues using the GitHub issue tracker. + + +30 March 2014 +------------- + +I've just released gflags 2.1.1. + +This release fixes a few bugs in the configuration of gflags\_declare.h +and adds a separate GFLAGS\_INCLUDE\_DIR CMake variable to the build configuration. +Setting GFLAGS\_NAMESPACE to "google" no longer changes also the include +path of the public header files. This allows the use of the library with +other Google projects such as glog which still use the deprecated "google" +namespace for the gflags library, but include it as "gflags/gflags.h". + +20 March 2014 +------------- + +I've just released gflags 2.1. + +The major changes are the use of CMake for the build configuration instead +of the autotools and packaging support through CPack. The default namespace +of all C++ symbols is now "gflags" instead of "google". This can be +configured via the GFLAGS\_NAMESPACE variable. + +This release compiles with all major compilers without warnings and passed +the unit tests on Ubuntu 12.04, Windows 7 (Visual Studio 2008 and 2010, +Cygwin, MinGW), and Mac OS X (Xcode 5.1). + +The SVN repository on Google Code is now frozen and replaced by a Git +repository such that it can be used as Git submodule by projects. The main +hosting of this project remains at Google Code. Thanks to the distributed +character of Git, I can push (and pull) changes from both GitHub and Google Code +in order to keep the two public repositories in sync. +When fixing an issue for a pull request through either of these hosting +platforms, please reference the issue number as +[described here](https://code.google.com/p/support/wiki/IssueTracker#Integration_with_version_control). +For the further development, I am following the +[Git branching model](http://nvie.com/posts/a-successful-git-branching-model/) +with feature branch names prefixed by "feature/" and bugfix branch names +prefixed by "bugfix/", respectively. + +Binary and source [packages](https://github.com/schuhschuh/gflags/releases) are available on GitHub. + + +14 January 2014 +--------------- + +The migration of the build system to CMake is almost complete. +What remains to be done is rewriting the tests in Python such they can be +executed on non-Unix platforms and splitting them up into separate CTest tests. +Though merging these changes into the master branch yet remains to be done, +it is recommended to already start using the +[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration) branch. + + +20 April 2013 +------------- + +More than a year has past since I (Andreas) took over the maintenance for +`gflags`. Only few minor changes have been made since then, much to my regret. +To get more involved and stimulate participation in the further +development of the library, I moved the project source code today to +[GitHub](https://github.com/schuhschuh/gflags). +I believe that the strengths of [Git](http://git-scm.com/) will allow for better community collaboration +as well as ease the integration of changes made by others. I encourage everyone +who would like to contribute to send me pull requests. +Git's lightweight feature branches will also provide the right tool for more +radical changes which should only be merged back into the master branch +after these are complete and implement the desired behavior. + +The SVN repository remains accessible at Google Code and I will keep the +master branch of the Git repository hosted at GitHub and the trunk of the +Subversion repository synchronized. Initially, I was going to simply switch the +Google Code project to Git, but in this case the SVN repository would be +frozen and force everyone who would like the latest development changes to +use Git as well. Therefore I decided to host the public Git repository at GitHub +instead. + +Please continue to report any issues with gflags on Google Code. The GitHub project will +only be used to host the Git repository. + +One major change of the project structure I have in mind for the next weeks +is the migration from autotools to [CMake](http://www.cmake.org/). +Check out the (unstable!) +[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration) +branch on GitHub for details. + + +25 January 2012 +--------------- + +I've just released gflags 2.0. + +The `google-gflags` project has been renamed to `gflags`. I +(csilvers) am stepping down as maintainer, to be replaced by Andreas +Schuh. Welcome to the team, Andreas! I've seen the energy you have +around gflags and the ideas you have for the project going forward, +and look forward to having you on the team. + +I bumped the major version number up to 2 to reflect the new community +ownership of the project. All the [changes](ChangeLog.txt) +are related to the renaming. There are no functional changes from +gflags 1.7. In particular, I've kept the code in the namespace +`google`, though in a future version it should be renamed to `gflags`. +I've also kept the `/usr/local/include/google/` subdirectory as +synonym of `/usr/local/include/gflags/`, though the former name has +been obsolete for some time now. + + +18 January 2011 +--------------- + +The `google-gflags` Google Code page has been renamed to +`gflags`, in preparation for the project being renamed to +`gflags`. In the coming weeks, I'll be stepping down as +maintainer for the gflags project, and as part of that Google is +relinquishing ownership of the project; it will now be entirely +community run. The name change reflects that shift. + + +20 December 2011 +---------------- + +I've just released gflags 1.7. This is a minor release; the major +change is that `CommandLineFlagInfo` now exports the address in memory +where the flag is located. There has also been a bugfix involving +very long --help strings, and some other minor [changes](ChangeLog.txt). + +29 July 2011 +------------ + +I've just released gflags 1.6. The major new feature in this release +is support for setting version info, so that --version does something +useful. + +One minor change has required bumping the library number: +`ReparseCommandlineFlags` now returns `void` instead of `int` (the int +return value was always meaningless). Though I doubt anyone ever used +this (meaningless) return value, technically it's a change to the ABI +that requires a version bump. A bit sad. + +There's also a procedural change with this release: I've changed the +internal tools used to integrate Google-supplied patches for gflags +into the opensource release. These new tools should result in more +frequent updates with better change descriptions. They will also +result in future `ChangeLog` entries being much more verbose (for better +or for worse). + +See the [ChangeLog](ChangeLog.txt) for a full list of changes for this release. + +24 January 2011 +--------------- + +I've just released gflags 1.5. This release has only minor changes +from 1.4, including some slightly better reporting in --help, and +an new memory-cleanup function that can help when running gflags-using +libraries under valgrind. The major change is to fix up the macros +(`DEFINE_bool` and the like) to work more reliably inside namespaces. + +If you have not had a problem with these macros, and don't need any of +the other changes described, there is no need to upgrade. See the +[ChangeLog](ChangeLog.txt) for a full list of changes for this release. + +11 October 2010 +--------------- + +I've just released gflags 1.4. This release has only minor changes +from 1.3, including some documentation tweaks and some work to make +the library smaller. If 1.3 is working well for you, there's no +particular reason to upgrade. + +4 January 2010 +-------------- + +I've just released gflags 1.3. gflags now compiles under MSVC, and +all tests pass. I **really** never thought non-unix-y Windows folks +would want gflags, but at least some of them do. + +The major news, though, is that I've separated out the python package +into its own library, [python-gflags](http://code.google.com/p/python-gflags). +If you're interested in the Python version of gflags, that's the place to +get it now. + +10 September 2009 +----------------- + +I've just released gflags 1.2. The major change from gflags 1.1 is it +now compiles under MinGW (as well as cygwin), and all tests pass. I +never thought Windows folks would want unix-style command-line flags, +since they're so different from the Windows style, but I guess I was +wrong! + +The other changes are minor, such as support for --htmlxml in the +python version of gflags. + +15 April 2009 +------------- + +I've just released gflags 1.1. It has only minor changes fdrom gflags +1.0 (see the [ChangeLog](ChangeLog.txt) for details). +The major change is that I moved to a new system for creating .deb and .rpm files. +This allows me to create x86\_64 deb and rpm files. + +In the process of moving to this new system, I noticed an +inconsistency: the tar.gz and .rpm files created libraries named +libgflags.so, but the deb file created libgoogle-gflags.so. I have +fixed the deb file to create libraries like the others. I'm no expert +in debian packaging, but I believe this has caused the package name to +change as well. Please let me know (at +[[mailto:google-gflags@googlegroups.com](mailto:google-gflags@googlegroups.com) +google-gflags@googlegroups.com]) if this causes problems for you -- +especially if you know of a fix! I would be happy to change the deb +packages to add symlinks from the old library name to the new +(libgoogle-gflags.so -> libgflags.so), but that is beyond my knowledge +of how to make .debs. + +If you've tried to install a .rpm or .deb and it doesn't work for you, +let me know. I'm excited to finally have 64-bit package files, but +there may still be some wrinkles in the new system to iron out. + +1 October 2008 +-------------- + +gflags 1.0rc2 was out for a few weeks without any issues, so gflags +1.0 is now released. This is much like gflags 0.9. The major change +is that the .h files have been moved from `/usr/include/google` to +`/usr/include/gflags`. While I have backwards-compatibility +forwarding headeds in place, please rewrite existing code to say +``` + #include +``` +instead of +``` + #include +``` + +I've kept the default namespace to google. You can still change with +with the appropriate flag to the configure script (`./configure +--help` to see the flags). If you have feedback as to whether the +default namespace should change to gflags, which would be a +non-backwards-compatible change, send mail to +`google-gflags@googlegroups.com`! + +Version 1.0 also has some neat new features, like support for bash +commandline-completion of help flags. See the [ChangeLog](ChangeLog.txt) +for more details. + +If I don't hear any bad news for a few weeks, I'll release 1.0-final. diff --git a/third_party/gflags/WORKSPACE b/third_party/gflags/WORKSPACE new file mode 100644 index 0000000..f3707e9 --- /dev/null +++ b/third_party/gflags/WORKSPACE @@ -0,0 +1,6 @@ +# Copyright 2006 Google Inc.

It's +// pseudo-templatized: every operation on a FlagValue is typed.

It has a FlagValue for the flag's current value, but also +// the flag's name, type, etc. +// +// FlagRegistry is a collection of CommandLineFlags. There's the +// global registry, which is where flags defined via DEFINE_foo() +// live. But it's possible to define your own flag, manually, in a +// different registry you create. (In practice, multiple registries +// are used only by FlagSaver). +// +// A given FlagValue is owned by exactly one CommandLineFlag. A given +// CommandLineFlag is owned by exactly one FlagRegistry.

It needs to poke into +// the innards of the FlagValue->CommandLineFlag->FlagRegistry class +// hierarchy to do that. It's careful to acquire the FlagRegistry +// lock before doing any writing or other non-const actions. +// +// GetCommandLineOption is just a hook into registry routines to +// retrieve a flag based on its name.

If this +// flag is empty, nothing happens here. If it contains a string, +// however, then HandleCommandLineCompletions() will hijack the +// process, attempting to identify the intention behind this +// completion. Regardless of the outcome of this deduction, the +// process will be terminated, similar to --helpshort flag +// handling. +// +// ** Overview of Bash completions: +// Bash can be told to programatically determine completions for the +// current 'cursor word'. It does this by (in this case) invoking a +// command with some additional arguments identifying the command +// being executed, the word being completed, and the previous word +// (if any). Bash then expects a sequence of output lines to be +// printed to stdout. If these lines all contain a common prefix +// longer than the cursor word, bash will replace the cursor word +// with that common prefix, and display nothing. If there isn't such +// a common prefix, bash will display the lines in pages using 'more'. +// +// ** Strategy taken for command line completions: +// If we can deduce either the exact flag intended, or a common flag +// prefix, we'll output exactly that. Otherwise, if information +// must be displayed to the user, we'll take the opportunity to add +// some helpful information beyond just the flag name (specifically, +// we'll include the default flag value and as much of the flag's +// description as can fit on a single terminal line width, as specified +// by the flag --tab_completion_columns). Furthermore, we'll try to +// make bash order the output such that the most useful or relevent +// flags are the most likely to be shown at the top. +// +// ** Additional features: +// To assist in finding that one really useful flag, substring matching +// was implemented. Before pressing a to get completion for the +// current word, you can append one or more '?' to the flag to do +// substring matching. Here's the semantics: +// --foo Show me all flags with names prefixed by 'foo' +// --foo? Show me all flags with 'foo' somewhere in the name +// --foo?? Same as prior case, but also search in module +// definition path for 'foo' +// --foo??? Same as prior case, but also search in flag +// descriptions for 'foo' +// Finally, we'll trim the output to a relatively small number of +// flags to keep bash quiet about the verbosity of output. If one +// really wanted to see all possible matches, appending a '+' to the +// search word will force the exhaustive list of matches to be printed. +// +// ** How to have bash accept completions from a binary: +// Bash requires that it be informed about each command that programmatic +// completion should be enabled for. Example addition to a .bashrc +// file would be (your path to gflags_completions.sh file may differ): + +/* +$ complete -o bashdefault -o default -o nospace -C \ + '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \ + time env binary_name another_binary [...] +*/ + +// This would allow the following to work: +// $ /path/to/binary_name --vmodule +// Or: +// $ ./bin/path/another_binary --gfs_u +// (etc) +// +// Sadly, it appears that bash gives no easy way to force this behavior for +// all commands. That's where the "time" in the above example comes in. +// If you haven't specifically added a command to the list of completion +// supported commands, you can still get completions by prefixing the +// entire command with "env". +// $ env /some/brand/new/binary --vmod +// Assuming that "binary" is a newly compiled binary, this should still +// produce the expected completion output. + + +#ifndef GFLAGS_COMPLETIONS_H_ +#define GFLAGS_COMPLETIONS_H_ + +namespace @GFLAGS_NAMESPACE@ { + +extern void HandleCommandLineCompletions(void); + +} + +#endif // GFLAGS_COMPLETIONS_H_ diff --git a/third_party/gflags/src/gflags_completions.sh b/third_party/gflags/src/gflags_completions.sh new file mode 100755 index 0000000..c5fb7e6 --- /dev/null +++ b/third_party/gflags/src/gflags_completions.sh @@ -0,0 +1,117 @@ +#!/bin/bash + +# Copyright (c) 2008, Google Inc. +# All rights reserved. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions are +# met: +# +# * Redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer. +# * Redistributions in binary form must reproduce the above +# copyright notice, this list of conditions and the following disclaimer +# in the documentation and/or other materials provided with the +# distribution. +# * Neither the name of Google Inc. nor the names of its +# contributors may be used to endorse or promote products derived from +# this software without specific prior written permission. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +# "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +# A PARTICULAR PURPOSE ARE DISCLAIMED.

Before you use this module, please give the +// name of your internal namespace for this module. Or, if you want +// to expose it, you'll want to move it to the Google namespace. We +// cannot put this class in global namespace because there can be some +// problems when we have multiple versions of Mutex in each shared object. +// +// NOTE: by default, we have #ifdef'ed out the TryLock() method. +// This is for two reasons: +// 1) TryLock() under Windows is a bit annoying (it requires a +// #define to be defined very early). +// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG +// mode. +// If you need TryLock(), and either these two caveats are not a +// problem for you, or you're willing to work around them, then +// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs +// in the code below. +// +// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy: +// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html +// Because of that, we might as well use windows locks for +// cygwin. They seem to be more reliable than the cygwin pthreads layer. +// +// TRICKY IMPLEMENTATION NOTE: +// This class is designed to be safe to use during +// dynamic-initialization -- that is, by global constructors that are +// run before main() starts. The issue in this case is that +// dynamic-initialization happens in an unpredictable order, and it +// could be that someone else's dynamic initializer could call a +// function that tries to acquire this mutex -- but that all happens +// before this mutex's constructor has run. (This can happen even if +// the mutex and the function that uses the mutex are in the same .cc +// file.) Basically, because Mutex does non-trivial work in its +// constructor, it's not, in the naive implementation, safe to use +// before dynamic initialization has run on it. +// +// The solution used here is to pair the actual mutex primitive with a +// bool that is set to true when the mutex is dynamically initialized. +// (Before that it's false.) Then we modify all mutex routines to +// look at the bool, and not try to lock/unlock until the bool makes +// it to true (which happens after the Mutex constructor has run.) +// +// This works because before main() starts -- particularly, during +// dynamic initialization -- there are no threads, so a) it's ok that +// the mutex operations are a no-op, since we don't need locking then +// anyway; and b) we can be quite confident our bool won't change +// state between a call to Lock() and a call to Unlock() (that would +// require a global constructor in one translation unit to call Lock() +// and another global constructor in another translation unit to call +// Unlock() later, which is pretty perverse). +// +// That said, it's tricky, and can conceivably fail; it's safest to +// avoid trying to acquire a mutex in a global constructor, if you +// can. One way it can fail is that a really smart compiler might +// initialize the bool to true at static-initialization time (too +// early) rather than at dynamic-initialization time. To discourage +// that, we set is_safe_ to true in code (not the constructor +// colon-initializer) and set it to true via a function that always +// evaluates to true, but that the compiler can't know always +// evaluates to true. This should be good enough. +// +// A related issue is code that could try to access the mutex +// after it's been destroyed in the global destructors (because +// the Mutex global destructor runs before some other global +// destructor, that tries to acquire the mutex). The way we +// deal with this is by taking a constructor arg that global +// mutexes should pass in, that causes the destructor to do no +// work.

Once we receive it, we'll be able to +accept your pull requests. + +## Are you a Googler? + +If you are a Googler, please make an attempt to submit an internal contribution +rather than a GitHub Pull Request. If you are not able to submit internally, a +PR is acceptable as an alternative. + +## Contributing A Patch + +1. Submit an issue describing your proposed change to the + [issue tracker](https://github.com/google/googletest/issues). +2. Please don't mix more than one logical change per submittal, because it + makes the history hard to follow. If you want to make a change that doesn't + have a corresponding issue in the issue tracker, please create one. +3. Also, coordinate with team members that are listed on the issue in question. + This ensures that work isn't being duplicated and communicating your plan + early also generally leads to better patches. +4. If your proposed change is accepted, and you haven't already done so, sign a + Contributor License Agreement + ([see details above](#contributor-license-agreements)). +5. Fork the desired repo, develop and test your code changes. +6. Ensure that your code adheres to the existing style in the sample to which + you are contributing. +7. Ensure that your code has an appropriate set of unit tests which all pass. +8. Submit a pull request. + +## The Google Test and Google Mock Communities + +The Google Test community exists primarily through the +[discussion group](http://groups.google.com/group/googletestframework) and the +GitHub repository. Likewise, the Google Mock community exists primarily through +their own [discussion group](http://groups.google.com/group/googlemock). You are +definitely encouraged to contribute to the discussion and you can also help us +to keep the effectiveness of the group high by following and promoting the +guidelines listed here. + +### Please Be Friendly + +Showing courtesy and respect to others is a vital part of the Google culture, +and we strongly encourage everyone participating in Google Test development to +join us in accepting nothing less. Of course, being courteous is not the same as +failing to constructively disagree with each other, but it does mean that we +should be respectful of each other when enumerating the 42 technical reasons +that a particular proposal may not be the best choice. There's never a reason to +be antagonistic or dismissive toward anyone who is sincerely trying to +contribute to a discussion. + +Sure, C++ testing is serious business and all that, but it's also a lot of fun. +Let's keep it that way. Let's strive to be one of the friendliest communities in +all of open source. + +As always, discuss Google Test in the official GoogleTest discussion group. You +don't have to actually submit code in order to sign up. Your participation +itself is a valuable contribution. + +## Style + +To keep the source consistent, readable, diffable and easy to merge, we use a +fairly rigid coding style, as defined by the +[google-styleguide](https://github.com/google/styleguide) project. All patches +will be expected to conform to the style outlined +[here](https://google.github.io/styleguide/cppguide.html).

For that you can use CMake: + + mkdir mybuild + cd mybuild + cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR} + +To choose between building only Google Test or Google Mock, you may modify your +cmake command to be one of each + + cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests + cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests + +Make sure you have Python installed, as some of Google Test's tests are written +in Python.

Inside the statements, you can +// refer to the K-th (0-based) argument of the mock function by +// 'argK', and refer to its type by 'argK_type'. For example: +// +// ACTION(IncrementArg1) { +// arg1_type temp = arg1; +// return ++(*temp); +// } +// +// allows you to write +// +// ...WillOnce(IncrementArg1()); +// +// You can also refer to the entire argument tuple and its type by +// 'args' and 'args_type', and refer to the mock function type and its +// return type by 'function_type' and 'return_type'. +// +// Note that you don't need to specify the types of the mock function +// arguments. However rest assured that your code is still type-safe: +// you'll get a compiler error if *arg1 doesn't support the ++ +// operator, or if the type of ++(*arg1) isn't compatible with the +// mock function's return type, for example. +// +// Sometimes you'll want to parameterize the action. For that you can use +// another macro: +// +// ACTION_P(name, param_name) { statements; } +// +// For example: +// +// ACTION_P(Add, n) { return arg0 + n; } +// +// will allow you to write: +// +// ...WillOnce(Add(5)); +// +// Note that you don't need to provide the type of the parameter +// either. If you need to reference the type of a parameter named +// 'foo', you can write 'foo_type'. For example, in the body of +// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type +// of 'n'. +// +// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support +// multi-parameter actions. +// +// For the purpose of typing, you can view +// +// ACTION_Pk(Foo, p1, ..., pk) { ... } +// +// as shorthand for +// +// template +// FooActionPk Foo(p1_type p1, ..., pk_type pk) { ... } +// +// In particular, you can provide the template type arguments +// explicitly when invoking Foo(), as in Foo(5, false); +// although usually you can rely on the compiler to infer the types +// for you automatically. You can assign the result of expression +// Foo(p1, ..., pk) to a variable of type FooActionPk. This can be useful when composing actions. +// +// You can also overload actions with different numbers of parameters: +// +// ACTION_P(Plus, a) { ... } +// ACTION_P2(Plus, a, b) { ... } +// +// While it's tempting to always use the ACTION* macros when defining +// a new action, you should also consider implementing ActionInterface +// or using MakePolymorphicAction() instead, especially if you need to +// use the action a lot. While these approaches require more work, +// they give you more control on the types of the mock function +// arguments and the action parameters, which in general leads to +// better compiler error messages that pay off in the long run.

Inside +// the statements, you can refer to the value being matched by 'arg', +// and refer to its type by 'arg_type'. +// +// The description string documents what the matcher does, and is used +// to generate the failure message when the match fails. Since a +// MATCHER() is usually defined in a header file shared by multiple +// C++ source files, we require the description to be a C-string +// literal to avoid possible side effects. It can be empty, in which +// case we'll use the sequence of words in the matcher name as the +// description. +// +// For example: +// +// MATCHER(IsEven, "") { return (arg % 2) == 0; } +// +// allows you to write +// +// // Expects mock_foo.Bar(n) to be called where n is even. +// EXPECT_CALL(mock_foo, Bar(IsEven())); +// +// or, +// +// // Verifies that the value of some_expression is even. +// EXPECT_THAT(some_expression, IsEven()); +// +// If the above assertion fails, it will print something like: +// +// Value of: some_expression +// Expected: is even +// Actual: 7 +// +// where the description "is even" is automatically calculated from the +// matcher name IsEven. +// +// Argument Type +// ============= +// +// Note that the type of the value being matched (arg_type) is +// determined by the context in which you use the matcher and is +// supplied to you by the compiler, so you don't need to worry about +// declaring it (nor can you). This allows the matcher to be +// polymorphic. For example, IsEven() can be used to match any type +// where the value of "(arg % 2) == 0" can be implicitly converted to +// a bool. In the "Bar(IsEven())" example above, if method Bar() +// takes an int, 'arg_type' will be int; if it takes an unsigned long, +// 'arg_type' will be unsigned long; and so on. +// +// Parameterizing Matchers +// ======================= +// +// Sometimes you'll want to parameterize the matcher. For that you +// can use another macro: +// +// MATCHER_P(name, param_name, description_string) { statements; } +// +// For example: +// +// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; } +// +// will allow you to write: +// +// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n)); +// +// which may lead to this message (assuming n is 10): +// +// Value of: Blah("a") +// Expected: has absolute value 10 +// Actual: -9 +// +// Note that both the matcher description and its parameter are +// printed, making the message human-friendly. +// +// In the matcher definition body, you can write 'foo_type' to +// reference the type of a parameter named 'foo'. For example, in the +// body of MATCHER_P(HasAbsoluteValue, value) above, you can write +// 'value_type' to refer to the type of 'value'. +// +// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to +// support multi-parameter matchers. +// +// Describing Parameterized Matchers +// ================================= +// +// The last argument to MATCHER*() is a string-typed expression. The +// expression can reference all of the matcher's parameters and a +// special bool-typed variable named 'negation'. When 'negation' is +// false, the expression should evaluate to the matcher's description; +// otherwise it should evaluate to the description of the negation of +// the matcher. For example, +// +// using testing::PrintToString; +// +// MATCHER_P2(InClosedRange, low, hi, +// std::string(negation ? "is not" : "is") + " in range [" + +// PrintToString(low) + ", " + PrintToString(hi) + "]") { +// return low <= arg && arg <= hi; +// } +// ... +// EXPECT_THAT(3, InClosedRange(4, 6)); +// EXPECT_THAT(3, Not(InClosedRange(2, 4))); +// +// would generate two failures that contain the text: +// +// Expected: is in range [4, 6] +// ... +// Expected: is not in range [2, 4] +// +// If you specify "" as the description, the failure message will +// contain the sequence of words in the matcher name followed by the +// parameter values printed as a tuple. For example, +// +// MATCHER_P2(InClosedRange, low, hi, "") { ... } +// ... +// EXPECT_THAT(3, InClosedRange(4, 6)); +// EXPECT_THAT(3, Not(InClosedRange(2, 4))); +// +// would generate two failures that contain the text: +// +// Expected: in closed range (4, 6) +// ... +// Expected: not (in closed range (2, 4)) +// +// Types of Matcher Parameters +// =========================== +// +// For the purpose of typing, you can view +// +// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... } +// +// as shorthand for +// +// template +// FooMatcherPk +// Foo(p1_type p1, ..., pk_type pk) { ... } +// +// When you write Foo(v1, ..., vk), the compiler infers the types of +// the parameters v1, ..., and vk for you. If you are not happy with +// the result of the type inference, you can specify the types by +// explicitly instantiating the template, as in Foo(5, +// false). As said earlier, you don't get to (or need to) specify +// 'arg_type' as that's determined by the context in which the matcher +// is used. You can assign the result of expression Foo(p1, ..., pk) +// to a variable of type FooMatcherPk. This +// can be useful when composing matchers. +// +// While you can instantiate a matcher template with reference types, +// passing the parameters by pointer usually makes your code more +// readable. If, however, you still want to pass a parameter by +// reference, be aware that in the failure message generated by the +// matcher you will see the value of the referenced object but not its +// address. +// +// Explaining Match Results +// ======================== +// +// Sometimes the matcher description alone isn't enough to explain why +// the match has failed or succeeded. For example, when expecting a +// long string, it can be very helpful to also print the diff between +// the expected string and the actual one. To achieve that, you can +// optionally stream additional information to a special variable +// named result_listener, whose type is a pointer to class +// MatchResultListener: +// +// MATCHER_P(EqualsLongString, str, "") { +// if (arg == str) return true; +// +// *result_listener << "the difference: " +/// << DiffStrings(str, arg); +// return false; +// } +// +// Overloading Matchers +// ==================== +// +// You can overload matchers with different numbers of parameters: +// +// MATCHER_P(Blah, a, description_string1) { ... } +// MATCHER_P2(Blah, a, b, description_string2) { ... } +// +// Caveats +// ======= +// +// When defining a new matcher, you should also consider implementing +// MatcherInterface or using MakePolymorphicMatcher(). These +// approaches require more work than the MATCHER* macros, but also +// give you more control on the types of the value being matched and +// the matcher parameters, which may leads to better compiler error +// messages when the matcher is used wrong.
