This DCHECK() was not correct. When dumping a process with CET
enabled the cetumsr and cetussp registers are not available in
the context obtained for the exception record. All contexts to be
written to a minidump must have the same context format so those
registers will be present for captured threads. It is therefore ok for
the context to expect extended xsave registers but for them to be
zero in some cases.

These are slightly frustrating. First, when a struct is packed, some of
its fields may be underaligned. This is fine for direct access
(foo.bar), but if one takes the address if the field, this creates an
unaligned pointer. Dereferencing that pointer is then UB. (I'm not sure
if creating that pointer is UB.)
Crashpad seemingly doesn't do this, but it uses EXPECT_EQ from GTest.
EXPECT_EQ seems to internally take pointers to its arguments. I'm
guessing it binds them by const reference. This then trips UBSan. To
avoid this, we can copy the value into a temporary before passing to
EXPECT_EQ.
Second, the test to divide by 0 to trigger SIGFPE is undefined behavior.
The compiler is not actually obligated to trip SIGFPE. UBSan prints one
of its errors instead. Instead, since this file is only built on POSIX
anyway, use GCC inline assembly to do the division. That one is
well-defined.
Finally, casting a string to uint32_t* is undefined both by alignment
and by strict aliasing (although Chromium doesn't enable the latter).
Instead, type-punning should be done with memcpy.

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].

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.

There are GN variables that may need to be updated when Fuchsia's source
re-organizes its layout:
* mini_chromium_source_parent : this contains a BUILD.gn with groups and
encloses the mini_chromium_source_root. This is controlled by the
structure of the project that depends on this project.
* _mini_chromium_source_root : this is what is normally checked out from
git, the upstream source directory
* mini_chromium_import_root : points inside source_root to make GN files
accessible.
This first step breaks out case logic for "if (crashpad_is_in_fuchsia)"
even if the value is unchanged for now. This will faciliate a smaller

Windows; this is a 32-bit type as opposed to time_t, which is a 64-bit

triggering the warning.
It's not possible to cast directly to __kernel_old_time_t, since that
type is not exposed here. Instead, cast to the underlying type, long,
which should work correctly on all platforms.
This has Year 2038 problems (which is why time_t is switching to

moving away from using timeval anywhere (?). I'm not really certain
what all would be involved in trying to make this whole pipeline

The macOS 11.0 SDK, as of Xcode 12b6 12A8189n, has not updated
<AvailabilityMacros.h> with a MAC_OS_X_VERSION_11_0 or
MAC_OS_X_VERSION_10_16 constant. However, the <Availability.h> interface
has been updated to provide both __MAC_11_0 and __MAC_10_16.
<AvailabilityMacros.h>’s MAC_OS_X_VERSION_MAX_ALLOWED, which is supposed
to identify the SDK version, is broken in the 11.0 SDK in that whenever
the deployment target is set to 10.15 or earlier, the SDK will be
mis-identified through this interface as 10.15. When using the
<Availability.h> equivalent, __MAC_OS_X_VERSION_MAX_ALLOWED, the 11.0
SDK is identified as 10.16 (arguably it should be internally versioned
as 11.0, but at least this interface allows it to be detected
unambiguously.) It’s clear that the <AvailabilityMacros.h> interface
provides no meaningful support for the macOS 11.0 SDK at all, but
<Availability.h> does.
<Availability.h> was introduced in the Mac OS X 10.5 SDK, so there is no
relevant SDK version compatibility problem with this interface.
Key differences between these interfaces for the purposes used by
Crashpad:
- <AvailabilityMacros.h> → <Availability.h>
- MAC_OS_X_VERSION_MIN_REQUIRED (DT) → __MAC_OS_X_VERSION_MIN_REQUIRED
- MAC_OS_X_VERSION_MAX_ALLOWED (SDK) → __MAC_OS_X_VERSION_MAX_ALLOWED
- MAC_OS_X_VERSION_x_y → __MAC_x_y
- <Availability.h> __MAC_OS_X_VERSION_* SDK/DT macros are only
available when targeting macOS, while <AvailabilityMacros.h>
MAC_OS_X_VERSION_* SDK/DT macros are available on all Apple platforms,
which may be a source of confusion. (<Availability.h> __MAC_* macros
do remain available on all Apple platforms.)

Chromium relies on a global gn sources assignment filter, even though
it’s kind of discouraged. Crashpad doesn’t use this, instead selecting
which files to build entirely with the logic in its .gn files. In some
cases, Chromium’s filters prevent _linux files from building on Android,
and _mac files from building on iOS, even though Crashpad’s build has
explicitly requested these inclusions. To overcome this problem,
clear the gn sources_assignment_filter in all of Crashpad’s own .gn
files when building in Chromium.

If the file just needs the CHECK/CHECK_OP/NOTREACHED
macros, use the appropriate header for that instead.
Or if logging.h is not needed at all, remove it.
This is both a nice cleanup (logging.h is a big header,
and including it unnecessarily has compile-time costs),
and part of the final step towards making logging.h no
longer include check.h and the others.

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.

From cl/304219049:
Optimize C++11 range-based for loops where the variable is copied in
each iteration but it would suffice to obtain it by const reference.
This is only applied to loop variables of types that are expensive to
copy which means they are not trivially copyable or have a non-trivial
copy constructor or destructor.
To ensure that it is safe to replace the copy with a const reference,
the following heuristic is employed:
- The loop variable is const qualified.
- The loop variable is not const, but only const methods or operators
are invoked on it, or it is used as const reference or value argument
in constructors or function calls.

Causes MinidumpMemoryListWriter to merge all overlapping ranges before
writing the MINIDUMP_MEMORY_LIST. This is:
1) Necessary for the Google internal crash processor, which in some
cases attempts to read the raw memory (displaying ASAN red zones),
and aborts if there are any overlapping ranges in the minidump on
load;
2) Necessary for new-ish versions of windbg (see bug 216 below). It is
believed that this is a change in behavior in the tool that made
dumps with overlapping ranges unreadable;
3) More efficient. The .dmp for crashy_program goes from 306K to 140K
with this enabled. In Chrome minidumps where
set_gather_indirectly_referenced_memory() is used (in practice this
means Chrome Windows Beta, Dev, and Canary), the savings are expected
to be substantial.

In doing standalone bringup of Crashpad targeting Fuchsia, it seemed
tidy to keep the same literal paths to the dependencies that Chromium
needed and add stubs/forwarding to build/secondary in the Crashpad tree
as required to make those work.
However, when trying to build Crashpad in the Fuchsia tree itself, that
would require adding forwarding files to the Fuchsia tree to match the
Chromium directory structure, which would be awkward. Instead, have
explicit dependencies in the Crashpad tree that select the locations
for various dependencies.

- Adds some stub BUILD.gn files in locations where Chromium expects them
(in //build, //testing, //third_party) containing empty targets/configs.
These are no-ops in standalone builds, but add functionality when
building in Chromium. This is in preference to having a global bool
that conditionally does Chromium-y things in the Crashpad build files.
These stub files are all contained in a secondary source root in
build/chromium_compatibility, referred to by //.gn.
- Adds //base/BUILD.gn which forwards to mini_chromium/base. This is
only used when building standalone so that both Chromium and Crashpad
can refer to it as "//base".
- Changes references to other Crashpad targets to be relatively
specified so that they work when the root of the project is //, and also
when it's //third_party/crashpad/crashpad as it is in Chromium.
- Moves any error-causing Mac/Win-specific files into explicit if (is_mac)

As yet unresolved:
- CRASHPAD_IN_CHROMIUM needs to be removed when standalone; to be tackled
in a follow up.
- Not sure what to do with zlib yet, the build file currently assumes
"in Chromium" too, and similarly having Crashpad //third_party/zlib:zlib
pointing at itself doesn't work.

Crashpad has many tests that crash intentionally. Some of these are
gtest death tests, and others arrange for intentional crashes to test
Crashpad’s own crash-catching logic. On macOS, all of the gtest death
tests and some of the other intentional crashes were being logged by
ReportCrash, the system’s crash reporter. Since these reports
corresponded to intentional crashes, they were never useful, and served
only to clutter ~/Library/Logs/DiagnosticReports.
Since Crashpad is adept at handling exceptions on its own, this
introduces the “exception swallowing server”,
crashpad_exception_swallower, which is a Mach exception server that
implements a no-op exception handler routine for all exceptions
received. The exception swallowing server is established as the task
handler for EXC_CRASH and EXC_CORPSE_NOTIFY exceptions during gtest
death tests invoked by {ASSERT,EXPECT}_DEATH_{CHECK,CRASH}, and for all
child processes invoked by the Multiprocess test infrastructure. The
exception swallowing server is not in effect at other times, so
unexpected crashes in test code can still be handled by ReportCrash or
another crash reporter.
With this change in place, no new reports are generated in the
user-level ~/Library/Logs/DiagnosticReports or the system’s
/Library/Logs/DiagnosticReports during a run of Crashpad’s full test
suite on macOS.

While making crashpad_minidump_test run in Chromium’s try- and buildbots
(https://crbug.com/779790), crashes in the
MinidumpThreadWriter.OneThread_AMD64_Stack test were observed in 32-bit
x86 Windows builds produced by Clang in the release configuration. These
crashes occurred in crashpad::test::InitializeMinidumpContextAMD64,
which heap-allocates a MinidumpContextAMD64Writer object. These objects
have an alignment requirement of 16, based on the alignment requirement
of their MinidumpContextAMD64 member.
Although this problem was never observed with MSVC, Clang was making use
of the known strict alignment and producing code that depended on it.
This code crashed if the requirement was not met. MSVC had raised a
warning about this usage (C4316), but the warning was disabled as it did
not appear to have any ill effect on code produced by that compiler.
The problem surfaced in test code, but heap-allocated
MinidumpContextAMD64Writer objects are created in non-test code as well.
The impact is limited, because a 32-bit Windows Crashpad handler would
not have a need to allocate one of these objects.
As a fix, MinidumpContextAMD64Writer is given a custom allocation

Update mini_chromium to 7d6697ceb5cb5ca02fde3813496f48b9b1d76d0c
47ff9691450e Switch the language standard to C++14
7d6697ceb5cb Remove base/memory/ptr_util.h and base::WrapUnique
base::WrapUnique and std::make_unique are similar, but the latter is
standardized and preferred.
Most of the mechanical changes were made with this sed:
for f in $(git grep -l base::WrapUnique | uniq); do
sed -E \
-e 's%base::WrapUnique\(new ([^(]+)\((.*)\)\);%std::make_unique<\1>(\2);%g' \
-e 's%base::WrapUnique\(new ([^(]+)\);%std::make_unique<\1>();%g' \
-e 's%^#include "base/memory/ptr_util.h"$%#include <memory>%' \
-i '' "${f}"
done
Several uses of base::WrapUnique that did not fit on a single line and
were not matched by this sed were adjusted manually. All #include
changes were audited manually, to at least move <memory> into the
correct section. Where <memory> was already #included by a file (or its
corresponding header), the extra #include was removed. Where <memory>
should have been #included by a header, it was added. Other similar
adjustments to other #includes were also made.

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.

Use the standard alignas instead of ALIGNAS in cases where this is
possible too. It’s not currently possible where ALIGNAS may be mixed
with other attributes, although the not-landed
https://codereview.chromium.org/2670873002/ suggests that where ALIGNAS
is mixed with __attribute__((packed)), it’s viable to write “struct
alignas(4) S { /* … */ } __attribute__((packed));”.

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.

After b10d9118dea4, the MemoryListStream was moved from its preferred
position as the last stream in the file to precede user minidump
streams, in an effort to prevent it from being preempted by a user
minidump stream that specified the memory list stream’s type. A better
solution, which keeps all streams where they want to be, is to put the
MemoryListStream at the end, put user streams before it, and omit user
streams that purport to be a MemoryListStream.
