6d0d1a4be6 [minidump] Add support for THREAD_NAME_LIST stream
The minidump stream type MINIDUMP_THREAD_NAME_LIST represents
thread names as a list in the form [(thread_id, thread name), ...].

This introduces a new MinidumpThreadNameListWriter class which
allows OS-specific snapshot writers to write thread names using
this new stream type.

9e0051aba6 Write compacted xsave contexts in minidumps
Adds new structures and offsets for minidump extended contexts. This
information will be captured from threads in a later CL so this CL
does not yet write different dumps, except in testing.

Minidump format for extended compacted contexts has been determined by
experiment. Offsets for where to write various parts of the context
are hardcoded to 0x550 as this matches values seen in Windows. Offsets
for misc_info_5 match those seen in working minidumps that can be opened
in windbg. Our hope is that while these could change in future, CPU
and OS vendors are unlikely to change them.

See doc[0] for a discussion of these fields and offsets in the minidump.

See "MANAGING STATE USING THE XSAVE FEATURE SET" Chapter 13 in the
Intel SDM[1]. Many of the offsets and sizes of the extended features
are provided by cpu specific values. We can access these in Windows
using the SDK, and transfer these to the saved extended context
which in turn is understandable by windbg.

Further information is available from AMD Ch. 18 "Shadow Stacks"[2].

1aa478d161 Remove DISALLOW_* macros in crashpad
This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.

The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.

For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.

#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

a45eea40fc Update gtest to e3f0319d89f4cbf32993de595d984183b1a9fc57
I’m most interested in picking up 1b3eb6ef3462, “Explicitly define copy
constructors used in googletest tests.”

This also reorganizes files and rewrites text to refer to this project
as Google Test and googletest (and Google Mock and googlemock), as it
prefers to be known. Some filenames are left at gtest_* following the
precedent set by gtest itself. For example, #include "gtest/gtest.h" is
still used, so #include "test/gtest_death.h" is retained too.
gtest_all_test OutputFileHelpersTest.GetCurrentExecutableName hard-codes
the expected executable name as gtest_all_test among other options that
do not include googletest_all_test, so test executables retain their
names as well.

cc166d71f4 Use base::size where appropriate, and ArraySize elsewhere
This is a follow-up to c8a016b99d97, following the post-landing
discussion at
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/1393921/5#message-2058541d8c4505d20a990ab7734cd758e437a5f7

base::size, and std::size that will eventually replace it when C++17 is
assured, does not allow the size of non-static data members to be taken
in constant expression context. The remaining uses of ArraySize are in:

minidump/minidump_exception_writer.cc (×1)
minidump/minidump_system_info_writer.cc (×2, also uses base::size)
snapshot/cpu_context.cc (×4, also uses base::size)
util/misc/arraysize_test.cc (×10, of course)

The first of these occurs when initializing a constexpr variable. All
others are in expressions used with static_assert.

7c6d2334a9 Don't fail minidump write if memory snapshot read fails
On Windows (and probably elsewhere) it's possible that something else on
the system changes the memory map between when a memory snapshot range
is added to the minidump, and when the process's memory is actually read
from the target and written to the .dmp file. As a result, failing the
Read() should not result in aborting the minidump's write, which it
previously would have.

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.

546e64cd0b Centrally define CPUContextX86::Fsave and fsave↔︎fxsave conversions
As I was finishing d98a4de718d9, it became evident that fsave
proliferation was becoming a problem. Especially considering tests,
there was much duplicated conversion code. This ties everything up
together in a central location.

test::BytesToHexString() is a new function to ease testing of byte
arrays like x87 registers, without having to loop over each byte.

Some static_asserts are added to verify that complex structures that
need to maintain interoperability don’t grow or shrink. This is used
to check the size of the fxsave and fsave structures, as well as the
MinidumpCPUContext* structures.

c6f88d164e Have MinidumpMemoryListWriter deal directly in SnapshotMinidumpMemoryWriters
This is as a precursor to
https://chromium-review.googlesource.com/374539 which merges
MemorySnapshots and so needs to be able to update them from the minidump
code.

MinidumpMemoryWriter existed to be able to mock for tests; that
behaviour is wrapped up in TestMemorySnapshot now.

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,
which removes base/basictypes.h.

e128dcf10122 Remove base/move.h; use std::move() instead of Pass()

07fcf63c21 win: fixes for Windows x64
Mostly size_t <-> unsigned int warnings, but I also had a mistake in
PROCESS_BASIC_INFORMATION, the pids are 32-on-32 and 64-on-64.

The Windows build is still x86 until https://codereview.chromium.org/981333002/.
I don't think I'll bother maintaining the x86 build for now, though we will probably
need it for x86 OSs in the future. It should be straightforward to revive it once we
need it, and have bots to support it.

4539fd1553 minidump: Reorganize MinidumpModuleCrashpadInfo to improve linking
between classic and extension structures.

Previosly, each MinidumpModuleCrashpadInfo structure contained a
minidump_module_list_index field referencing a module in the
MINIDUMP_MODULE_LIST stream by index. This layout was discovered to
cause a problem for the new minidump reader in ModuleSnapshotMinidump.
Instead, the module list index for linkage should be contained in the
MinidumpModuleCrashpadInfoList alongside the LOCATION_DESCRIPTORs
pointing to each MinidumpModuleCrashpadInfo.

The organizational difference is small, but this enables a better design
for ModuleSnapshotMinidump. When initializing a ModuleSnapshotMinidump
with the new layout, it is possible for the caller to have access to the
location descriptor for the MinidumpModuleCrashpadInfo corresponding to
a MINIDUMP_MODULE_LIST. Previously, the caller would not have had this
data without interpreting each MinidumpModuleCrashpadInfo, which
ModuleSnapshotMinidump would have to do anyway.

MinidumpModuleCrashpadInfoListWriter was the only user of
MinidumpLocationDescriptorListWriter, which is obsoleted and removed in
this change. Its functionality is moving directly into
MinidumpModuleCrashpadInfoListWriter, but it is no longer generic enough
to maintain as a distinct class.

This will be used as the foundation for writing a list of
MinidumpUTF8String objects. MinidumpUTF8String (and UTF-16
MINIDUMP_STRING) objects are never referenced by
MINIDUMP_LOCATION_DESCRIPTOR because they carry their own lengths.
Instead, they are always referenced by RVA.

The list of MinidumpUTF8String objects will be used for the module
annotations vector.

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.

and its test.

Minidump context structures now interoperate more easily with snapshot
CPUContext structures, while maintaining identical layout to before.
This is facilitated by reusing the Fxsave types for the substructures
which were completely identical, and by using compatible logic to
initialize the minidump and snapshot structures for testing.
