828095ac32 Clear the gn sources_assignment_filter when building in Chromium
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.

161bfed35a Remove/replace unnecessary includes of logging.h
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.

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.

194e23910c Change for loops to use const references where they did not previously
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.

d9c1ca1216 [ios] Bring up first draft system snapshot and iOS data collector.
Gather most of the necessary information for the system snapshot.

Note that:
 - The 'capture' portion of this CL will be moved out of the snapshot
   interface and into a separate in-process dump to disk location.
 - All of the pointer dereferences need to be wrapped in vm_read.
 - The read-fast-and-dump logic in thread_snapshot may end up in a
   different file completely, but until we pick a
   serialization/deserialization method, keep it as-is.

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.

9b6c69cbb5 Coalesce memory ranges
Follows https://chromium-review.googlesource.com/c/374019/.

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.

Fuchsia builds with -Wmissing-field-initializers. Remove these {0}s. It
all seems a bit awful, but as far as I can tell from reading
http://en.cppreference.com/w/cpp/language/aggregate_initialization, the
0 is unnecessary.

457cc6a34f gn: Refactor build files to avoid build/secondary
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.

2bb56fafe3 Rework GN files to start to support building standalone, and also in Chromium
- Adds a .gn and a build/BUILDCONFIG.gn that uses mini_chromium's
  build/BUILD.gn.
- 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)
  or if (is_win) blocks as part of removing the dependency on
  set_sources_assignment_filter().

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.

94a5a72efa mac: Tests that crash intentionally shouldn’t go to ReportCrash
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.

d5ead4d70f Upstream lightly modified Chromium BUILD.gn files
Unreferenced, and not working at all in Crashpad-standalone.

Copied from Chromium at 52a9831d81f2099ef9f50fcdaca5853019262c35 to have
a point where a roll back into Chromium should be a no-op (with Chromium's
build/secondary/third_party/crashpad/... removed).

I'm not sure what we want to do about the various gni references into
Chromium (e.g. //build/config/sanitizers/sanitizers.gni, //testing/test.gni,
etc.) but I guess the sooner they live in Crashpad rather than in Chromium
the sooner we can figure out the sort of knobs and dials we need.

af594c8deb Heap-allocate MinidumpContextAMD64Writer objects with proper alignment
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
function (a static “operator new()” member and matching “operator
delete()”) that returns properly aligned memory.

7a849482ea Switch the language standard to C++14 and use std::make_unique
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.
