zmq_ppoll mostly mimics zmq_poll behavior, except for the added feature of being able to specify a signal mask. Signals in this mask will be blocked during execution of zmq_ppoll. Switching of the process' active signal mask happens atomically with the actual poll call, so that no race conditions can occur. This behavior is useful when one wants to gracefully handle POSIX signals without race conditions. See e.g. the discussion below https://250bpm.com/blog:12/ for an explanation.
Also includes two new tests:
1. test_zmq_ppoll_fd does the same thing as test_zmq_poll_fd, demonstrating backwards compatibility with zmq_poll when used with a default signal mask.
2. test_zmq_ppoll_signals demonstrates the use of zmq_ppoll with a signal mask, blocking out SIGTERM everywhere except in zmq_ppoll, allowing to handle the signal in one place without having to worry about race conditions.
This is important in order to send the login sequence of a client to the server.
Solution: add ZMQ_HICCUP_MSG to a socket, socket would send that message whenever a connection get temporarly disconnected
Solution: port the 2 new tests from oss-fuzz, and wire them up to
be ran manually with a static input in normal builds.
Add a specific configure option to use the external fuzzing engine
from oss-fuzz.
* Allow CMAKE to generate ws and wss transports
I guess there is little use of just ws transport, so by default
GnuTLS (and libsodium) are enabled
* cmake libzmq including wss transport (ubuntu 19.10 and ubuntu 19.10 + wsl 1.0)
test_security_fails (libsodium assert !?)
* updated relicense
* make external libs gnutls nss sodium optional
* #ifdef WSS classes and functions, build test*ws* only if correct libs are included, warning if libs not present
* make libsodium optional
* cmake fix tests TIPC transport
* clang-format pointed out a wrongly placed #ifdef
* GnuTLS before 3.6.7 is not safe
* msvc doesn't agree with strlen in array declaration, test_socks now at least compiles on windows
* windows: libsodium build fails, missing include dirs set by env var
* ws transport test only works when GnuTLS is found
* Fixed condition to use NSS / built in SHA1, so that test_ws_transport should now pass, also when GnuTLS is not found
Solution: a new socket type, called PEER. Very similar to SERVER, but can only connect to other PEERs. Also a new zmq_connect_peer method, that connect and return a routing-id in thread-safe and atomic operation
* Add ZMQ_XPUB_MANUAL_LAST_VALUE
* Surpport xpub send last value caching to one pipe with ZMQ_XPUB_MANUAL_LAST_VALUE
* Add test_xpubub_manual_last_value
* Add relicense and doc
- Lowercase all commands
- Unify indent to 2 spaces
- Remove spaces around brackets
- Remove repitition of condition in else(...) and endif(...)
Note: (re-)running CMake did not change the content of the generated files
Use ZeroMQ_SOURCE_DIR, ZeroMQ_BINARY_DIR instead of CMAKE_SOURCE_DIR, CMAKE_BINARY_DIR in tests/CMakeLists.txt
Similar reason to change unittests/CMakeLists.txt
Solution: add some msg helpers to parse commands, and check for
subscribe or cancel commands and process them accordingly in the xpub
and xsub classes.
Lets the application set per-connection metadata.
Metadata is specified as "X-key:value" and set using zmq_setsockopt, eg:
zmq_setsockopt (s, ZMQ_METADATA, "X-key:value", 11);
The peer can then obtain the metadata from a received message:
char *data = zmq_msg_gets(msg, "X-key");
* Problem: TIPC availability check is too strict
Solution: at build time only check if the API is available. In the tests
do a first check and a skip if the functionality is not available.
TIPC needs an in-tree but not loaded by default kernel module, tipc.ko
to be loaded, which requires root, so it is unlikely to be available on
any build system by default.
This will allow most distributions to ship with TIPC support built in,
and to avoid tests failure if the module is not there.
* Problem: no Travis tests for TIPC
Solution: mark one job with sudo: required and load the kernel module
* Problem: CMake fails when test returns 77 (skip)
Solution: set property to let it mark the test as skipped as intended
* Tests for different TIPC address types and code cleanup
* Adds tests for binding/connecting with different TIPC address types
using Unity
* Adds error checking for address type misuse
Solution: when a connection breaks and ZMQ_RECONNECT_IVL is set to -1,
which means a reconnection will not be attempted, send a message from
the I/O thread to the application thread to make the socket call
term_endpoint, which is the equivalent of manually calling
zmq_disconnect.
This way subsequent zmq_connect call to the same endpoint will attempt
again to do a connection.
Otherwise, for some socket types like SUBs, those new connects will
fail as the endpoint is recorded, despite the connection having been
permanently closed.
Add test cases to exercise this corner case with TCP and IPC.
* Extracted connect_vanilla_socket function

Solution: added two test cases with erroneous HELLO commands

Solution: extracted further parts of zmq::curve_client_t into reusable functions
added missing file

Solution: add non-static member functions
* Problem: msg_t instance may be closed twice
Solution: remove offending close

Solution: Use non-static curve_client_tools_t::produce_hello
* Problem: no test with invalid command name where INITIATE command is expected
Solution: added test case
* Problem: make builds are failing due to curve_client_tools.hpp not being found
Solution: add curve_client_tools.hpp to list of source files
* Problem: wrong initializer order in zmq::curve_client_t
Solution: reorder
* Problem: under non-Windows systems, test fails because random_open was not called
Solution: call random_open/random_close within test
* Problem: conflict between custom function htonll and macro definition on Darwin
Solution: define htonll function only if not defined as a macro
* Problem: nullptr not defined on all platforms
Solution: replace nullptr by NULL

* Problem: test_security_curve times out in CI
Solution: Increase timeout for this test to 20 seconds
Solution: use lower case ws2_32.lib to enable cross compilation
from platforms with case-sensitive filesystems.
When cross compiling the tests with Mingw-w64, CMake cannot
locate Ws2_32.lib
Remove the `build/msvc` include path from the test project to fix a
problem with the order of the include paths. Additionally remove the
unnecessary `include_directories` from the master project.

only if the library is found at a specific path
Solution: Search for libzmq.lib in ../bin/Win32/Debug/v120/dynamic, don't
know how to automatically search in correct path based on current build
configuration
Solution:
- Add file for testing ancillary API methods and any misc internal machinery
- Add tests for zmq_version(3) and zmq_strerror(3)
- Add test file into gitignore, Autotools and CMake build files
- Increase test coverage
Note:
MSVC solution files have not been updated.
Solution: PR #1906 did not solve this problem properly; subsequent Travis CI
indicated that the issue happens with Clang/LLVM, so make sure to fix the
issue by detecting if Cmake CMake is using Clang for building the tests.
Solution: add macro in ZMQSourceRunChecks.cmake and optionally
include the TIPC sources if the support is available.
More importantly, only run the TIPC tests if the support is there.
Problem:
A per-test Linker search path was added in commit a911fa4 to CMakeLists.txt as
part of fixing Windows builds. Whilst this is silently ignored by ld(1) on
Linux, it doesn't settle well with OS X. Spurious warnings are generated about
missing directories leading to convoluted build logs.
Solution:
Make per-Test LINK_DIRECTORIES() conditional for non-Apple platforms.
Move tests specific to Linux under a platform conditional thereby eliminating
unnecessary builds and fixing "make test" on Mac OS X and possibly other
non-Linux systems.
Tests specific to Linux:
- abstract namespace support for AF_UNIX sockets
- TIPC support (AF_TIPC)
Test success rate jumps from 90% to 100% on Mac OS X after this change.
Solution: remove temporarily until proper message limits have been
implemented, then a more granular test case can be added without
such high requirements which are problematic in embedded environment,
build systems, VMs and CI systems
Solution: Add precompiled flags to CMakeList.txt for faster compiles
+ bonus - removed compilation warning on Windows by adding
add_definitions (-D_WINSOCK_DEPRECATED_NO_WARNINGS)
Solution: Modified CMakelist.txt to build correctly for Windows
- corrected CMake required version to make sure it builds in
Ubuntu 14.04 LTS with no warnings.
