281be63d00 Standardize on static constexpr for arrays when possible
This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.

At namespace scope, “constexpr” is also used where appropriate.

For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.

Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to
arrays, there are far more use sites, and much more manual intervention
would be required.

4b450c8137 test: Use (actual, [un]expected) in gtest {ASSERT,EXPECT}_{EQ,NE}
gtest used to require (expected, actual) ordering for arguments to
EXPECT_EQ and ASSERT_EQ, and in failed test assertions would identify
each side as “expected” or “actual.” Tests in Crashpad adhered to this
traditional ordering. After a gtest change in February 2016, it is now
agnostic with respect to the order of these arguments.

This change mechanically updates all uses of these macros to (actual,
expected) by reversing them. This provides consistency with our use of
the logging CHECK_EQ and DCHECK_EQ macros, and makes for better
readability by ordinary native speakers. The rough (but working!)
conversion tool is
https://chromium-review.googlesource.com/c/466727/1/rewrite_expectassert_eq.py,
and “git cl format” cleaned up its output.

EXPECT_NE and ASSERT_NE never had a preferred ordering. gtest never made
a judgment that one side or the other needed to provide an “unexpected”
value. Consequently, some code used (unexpected, actual) while other
code used (actual, unexpected). For consistency with the new EXPECT_EQ
and ASSERT_EQ usage, as well as consistency with CHECK_NE and DCHECK_NE,
this change also updates these use sites to (actual, unexpected) where
one side can be called “unexpected” as, for example, std::string::npos
can be. Unfortunately, this portion was a manual conversion.

3983b80ca2 util/file: Handle oversized reads and writes gracefully
file_io and the FileReader family had a few loose ends regarding big
reads and writes. It’s not likely that we’ve experienced these
conditions yet, but they’d be likely to appear in a potential future
involving full memory dumps. This specifies the behavior with large
reads and writes, consolidates some logic, and improves some interfaces.

ReadFile() should always return without retrying after a short read, and
in fact does return after short reads since 00b64427523b. It is
straightforward to limit the maximum read size based on a parameter
limitation of the underlying operation, or a limitation of the type used
for FileOperationResult.

In contrast, WriteFile() should always retry after a short write,
including a write shortened because of a parameter limitation of the
underlying operation, or a limitation of the type used for
FileOperationResult. This allows its return value to be simplified to a
“bool”.

The platform-specific WriteFile() code has been moved to
internal::NativeWriteFile(), and the platform-independent loop that
retries following a short write has been refactored into
internal::WriteAllInternal so that it can be used by a new test.

The platform-agnostic ReadFileExactlyInternal() implementation has been
refactored into internal::ReadExactlyInternal so that it can be used by
a new test and by FileReaderInterface::ReadExactly(), which had a nearly
identical implementation.

Test: crashpad_util_test FileIO.ReadExactly_*:FileIO.WriteAll_*:FileReader.ReadExactly_*

4f90f15146 Remove WeakStdioFileReader and WeakStdioFileWriter
These classes were a bit of a hack, and one of the the reasons that
WeakStdioFileReader was introduced, accurate detection of EOF when stdin
is a terminal, will be obsolete once
https://chromium-review.googlesource.com/456676/ lands. In fact,
WeakStdioFileReader didn’t even work properly for this purpose on
Windows.

Use WeakFile{Reader,Writer} in place of these classes (there were only
two use sites). Provide a StdioFileHandle() function to access the
proper values to use as a FileHandle for native file I/O given each OS’
own interface.

00b6442752 Make file_io reads more rational and predictable
ReadFile() attempted to continue reading after a short read. In most
cases, this is fine. However, ReadFile() would keep trying to fill a
partially-filled buffer until experiencing a 0-length read(), signaling
end-of-file. For certain weird file descriptors like terminal input, EOF
is an ephemeral condition, and attempting to read beyond EOF doesn’t
actually return 0 (EOF) provided that they remain open, it will block
waiting for more input. Consequently, ReadFile() and anything based on
ReadFile() had an undocumented and quirky interface, which was that any
short read that it returned (not an underlying short read) actually
indicated EOF.

This facet of ReadFile() was unexpected, so it’s being removed. The new
behavior is that ReadFile() will return an underlying short read. The
behavior of FileReaderInterface::Read() is updated in accordance with
this change.

Upon experiencing a short read, the caller can determine the best
action. Most callers were already prepared for this behavior. Outside of
util/file, only crashpad_database_util properly implemented EOF
detection according to previous semantics, and adapting it to new
semantics is trivial.

Callers who require an exact-length read can use the new
ReadFileExactly(), or the newly renamed LoggingReadFileExactly() or
CheckedReadFileExactly(). These functions will retry following a short
read. The renamed functions were previously called LoggingReadFile() and
CheckedReadFile(), but those names implied that they were simply
wrapping ReadFile(), which is not the case. They wrapped ReadFile() and
further, insisted on a full read. Since ReadFile()’s semantics are now
changing but these functions’ are not, they’re now even more distinct
from ReadFile(), and must be renamed to avoid confusion.

51b21d8874 Add DelimitedFileReader and use it in Linux/Android’s ProcessInfo
This implements a non-stdio-based getline() equivalent. getline() is not
in the Android NDK until API 21 (Android 5.0.0), while Chrome builds for
32-bit platforms with API 16 (Android 4.1.0). Although a getline()
declaration could be provided in compat for use with older NDK headers,
it’s desirable to move away from stdio entirely. The C++
DelimitedFileReader interface is also a bit more comfortable to use than
getline().

A getdelim() equivalent is also provided, and is also used in the
Linux/Android ProcessInfo implementation.

e956a8252f Port the util library to Android
With this change, it is possible to build crashpad_util for Android with
clang. I built with NDK 13b (clang 3.8) at API 24 (current), API 21
(used by Chrome in 64-bit builds), and API 16 (used by Chrome in 32-bit
builds).

 - In WeakFileHandleFileWriter::WriteIoVec(): Android does not expose
   the IOV_MAX macro, but its value can be obtained by calling
   sysconf(_SC_IOV_MAX).
 - In CloseMultipleNowOrOnExec(): API 21 removes getdtablesize(). Skip
   it, because it returned the same thing as sysconf(_SC_OPEN_MAX),
   which is already consulted.
 - Throughout: Various #ifdefs checking for OS_LINUX have been extended
   to also check for OS_ANDROID. In Chrome’s build_config.h (and thus
   mini_chromium’s), OS_LINUX is not defined when OS_ANDROID is.

This has not been tested beyond building the crashpad_util target.

6d2d31d2d1 Use base/macros.h instead of base/basictypes.h
This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.

This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,

In a future change, when crashpad_util_test_lib gains a dependency on

ae1ccf621b handler: Add report upload.
The handler is now capable of uploading crash reports from the database.
At present, only one upload attempt is made, and the report will be
moved to “completed” in the database after the attempt, regardless of
whether it succeeded or failed.

The handler also has support to push annotations from its command line
into the process annotations map of each crash report it writes. This is
intended to set basic information about each crash report, such as the
product ID and version. Each potentially crashy process can’t be relied
on to maintain this information on their own.

With this change, Crashpad is now 100% capable of running a handler that
maintains a database and uploads crash reports to a Breakpad-type server
such that Breakpad properly interprets the reports. This is all possible
from the command line.

FileWriter from the FilePath, it’s not necessary to have two FileHandles
open to the same file. Also, there’s no FileWriteMode::kReuseOrFail
option because it didn’t seem necessary[1], and although it would
actually be the most desirable option for a FileWriter here, allowing
the FileHandle to be used directly without reopening the file sidesteps
the problem entirely.

FileWriter is adapted to use WeakFileHandleFileWriter to minimize
duplication.

892c29e8ba Reorganize Multiprocess and implement for Windows
- Various "FD" to "Handle"
- Existing Multiprocess implementation moves to _posix.
- Stub implementation for _win.

At the moment, multiprocess_exec_win.cc contains implementations of both
Multiprocess methods and MultiprocessExec functions. This will need more
work in the future, but reflects the idea that all tests should be in
terms of MultiprocessExec eventually.

Currently, this works sufficiently to have util_test succeed (including
multiprocess_exec_test, and the recently ported HTTPTransport tests.)

ac6a7455fd win: use FileOffset, not off_t in string_file_writer_test
off_t exists on Windows, but Seek is implemented in terms of
SetFilePointerEx which expects a LONGLONG, so FileOffset is LONGLONG.

So, use FileOffset in the test code so that it wraps at the expected
value.

4034d30023 Add LoggingOpenFileFor{Read|Write}
I started (https://codereview.chromium.org/812403002/) emulating oflag values
on Windows in FileWriter, but it seemed awkward. On the assumption that we're
only likely to need "read a file" and "write a file" this seemed simpler, and
sufficient (but I don't know if that's necessarily true).

Users of open are not yet switched.

10165ce449 Cross platform low level file IO wrappers
Rename fd_io to file_io, and ReadFD to ReadFile, etc.

file_io.cc is the higher level versions that call the basic ReadFile/WriteFile
and then file_io_posix.cc and file_io_win.cc are the implementations of
those functions.

The Windows path is as yet untested, lacking the ability to link the test binary.

48b1964d1b Use implicit_cast<> instead of static_cast<> whenever possible.
implicit_cast<> only performs a cast in cases where an implicit
conversion would be possible. It’s even safer than static_cast<> It’s an
“explicit implicit” cast, which is not normally necsesary, but is
frequently required when working with the ?: operator, functions like
std::min() and std::max(), and logging and testing macros.

The public style guide does not mention implicit_cast<> only because it
is not part of the standard library, but would otherwise require it in
these situations. Since base does provide implicit_cast<>, it should be
used whenever possible.

The only uses of static_cast<> not converted to implicit_cast<> are
those that require static_cast<>, such as those that assign an integer
constant to a variable of an enum type.
