Android 9+ sets the executable's dynamic array
address in the link map.

Improve tests to verify that the dynamic array
address in the link map matches the address in the

a8ff626764 Add a bunch of missing string.h includes.
There are a few files in the tree which use various functions defined
in string.h (memcpy, strlen, strnlen, memmove, etc), but never include
the necessary header file. After I've recently updated one of my systems
to a newer glibc version (2.30) this code failed to build. Adding the
missing includes fixes the problem.

The undeclared functions for each file are:
* simple_address_range_bag.h - memcpy
* http_multipart_builder.cc - strlen
* minidump_context_converter.cc - memcpy
* ptrace_client.cc - strlen
* http_transport_socket.cc - strncpy, strlen, memcpy
* process_memory.cc - memchr
* log_output_stream.cc - strlen

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.

a5a1c3b07f Add .style.yapf and reformat according to yapf, using “google” style
% yapf --in-place $(git ls-files **/*.py)
% yapf --version
yapf 0.30.0

Note that this is not using the “chromium” yapf style because Chromium
is moving to PEP-8.
https://groups.google.com/a/chromium.org/d/topic/chromium-dev/RcJgJdkNIdg
yapf 0.30.0 no longer recognizes “chromium” as a style option.
22ef70f3c4
Since this is a mass reformatting, it might as well move things all the
way into the future all at once.

This uses the “google” style, which is a superset of “pep8”.

7fa69e7e43 win: Remove disabled and flaky end-to-end tests
The “and not memory after range” follow-up to the “extra memory range
captured” test is very flaky in debug builds
(https://ci.chromium.org/p/crashpad/builders/ci/crashpad_win_dbg/388),
and occasionally flaky in release builds too
(https://ci.chromium.org/p/crashpad/builders/ci/crashpad_win_rel/363).
As with the already-disabled “extra memory removal” test, it’s likely
that Crashpad is discovering a pointer that references the memory
immediately beyond the intended range, and capturing that too. Unless
the environment is very tightly controlled, it’s difficult to prevent
valid memory from being pointed to, and thus to guarantee that Crashpad
won’t capture a particular block of memory.

These are probably never going to be fixed. The flaky tests are removed.

9a312ddff5 Increase kAllowedOffset for non-optimized build
"init_stack_vars = true" inserts additional instructions which
usually removed by optimization if code does not rely on undefined
behaviour of uninitialized variables.
However in non-optimized build these instructions may still be present.

0208c1a175 fuchsia: Don't capture incorrect/unreasonably large stacks
In a stack overflow test from the Fuchsia tree, an intentional crash was
being induced that at the point it was reported to Crashpad resulted in
a stack pointer outside of the stack. This caused two problems:

- Crashpad attempted to capture that whole "thing" which could have been
  anything, and in the failing test was a 1G guard region
- The whole wrong thing could be very large, resulting in OOM when
  trying to write the minidump, which was the symptom of the bug.

Don't attempt to continue of SP isn't at least in a mapping, and don't
capture too-large regions for the stack as nothing useful can come of
that anyway.

New test added: ProcessSnapshotFuchsiaTest.InvalidStackPointer.

cea103fb7d mac: Fix ProcessTypes.DyldImagesSelf with 10.14 SDK on 10.12
The current 10.14 SDK is numbered 101404, which is greater than
MAC_OS_X_VERSION_10_14 (101400). That was causing the test to
unintentionally fall into the “unlisted SDK” branch of the #if cascade
due to testing SDK <= MAC_OS_X_VERSION_10_14. This is corrected by
testing SDK < MAC_OS_X_VERSION_10_15 instead.

c009b85449 Use GTEST_SKIP() instead of custom DISABLED_TEST()
Since gtest 00938b2b228f, gtest has built-in first-class support for
skipping tests, which is functionally identical (at least in Crashpad’s
usage) to the home-grown support for run-time dynamically disabled tests
introduced in Crashpad 5e9ed4cb9f69.

Use the new standard pattern, and remove all vestiges of the custom
local one.

This was done previously in 79f4a3970a64, but was reverted in
bba9d0819c12 because Chromium’s test launcher did not support
GTEST_SKIP() at the time. The deficiency is on file as
https://crbug.com/912138.

While that bug was never specifically marked as “fixed” and I haven’t
found what changed in Chromium, I do now see some use of GTEST_SKIP() in
Chromium. I also prototyped this change in Chromium at
https://chromium-review.googlesource.com/c/1854691/ and found that
GTEST_SKIP() does indeed now appear to work.

2fb4e9e6a4 mac: Update the process_types version of dyld_all_image_infos for 10.15
macOS 10.15 (“Catalina”) introduces a single new field to its
dyld_all_image_infos structure, and uses structure version 16.

macOS 10.13 and 10.14 were documented in <mach-o/dyld_images.h> as using
structure version 16, but they actually use version 15. They should have
used version 16, as they do use a structure expanded from macOS 10.12,
which also uses version 15. Previously, process_types was true to the
documentation, but now that this is known to be incorrect, it’s been
revised to reflect reality. Because two variants of the version 15
structure exist, run-time OS version detection is used to disambiguate.

db6f51d3fc fuchsia: Check results of Initialize() subcalls in ProcessReaderFuchsia
From looking at some syzkaller logs, the earliest error seems to be

  [...ERROR memory_map_fuchsia.cc:47] zx_object_get_info ZX_INFO_PROCESS_MAPS: ZX_ERR_BAD_STATE (-20)

which might be caused by a failure to suspend. That error causes
ProcessReaderFuchsia's memory_map_ Initialize() to fail, but that was
mistakenly being ignored. Later calls then fail as well.

While we're here, also check a couple other Initialize()s that were
sometimes triggering later on.

efaebfc482 fuchsia: Capture from SP (+slop) to stack base, rather than entire stack
Stack mappings can be enormous for some processes dwarfing all other
data and making the .dmp useless. It isn't useful to capture beyond the
stack pointer, so grab only from the stack base to the stack pointer.

In the default config (safestack enabled), this isn't a major problem.
However, Chromium has safestack disabled, along with a large stack size,
so dumps with many threads become very large.

6225d78906 Don't use a regex to test the CPU vendor string.
This test will break if there is an unusual character in the vendor
string. Moreover, std::regex is banned in Chromium so the test is
blocking the roll.

Probably all that can meaningfully be tested here is that the vendor
string is non-empty, so do that instead.
