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.

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.

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.

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,
which removes base/basictypes.h.

After 9e79ea1da719, it no longer makes sense for crashpad_util_test_lib
to “hide” in util/util_test.gyp. All of util/test is moved to its own
top-level directory, test, which all other test code is allowed to
depend on. test, too, is allowed to depend on all other non-test code.
In a future change, when crashpad_util_test_lib gains a dependency on
crashpad_client, it won’t look so weird for something in util (even
though it’s in util/test) to depend on something in client, because the
thing that needs to depend on client will live in test, not util.
