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.

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.

281be63d00 Standardize on static constexpr for arrays when possible
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.

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.

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.

809ea8158d test: Move util/test to its own top-level directory, test.
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.

26804a0be1 Add ASSERT_DEATH_CHECK() to do ASSERT_DEATH() of CHECK() failures.
Likewise for EXPECT_DEATH_CHECK() and EXPECT_DEATH().

In the in-Chromium build configured for official builds in Release mode,
CHECK() throws away its condition string and stream parameters without
ever printing them, although it still evaluates the condition and
triggers death appropriately. {ASSERT,EXPECT}_DEATH(statement, regex)
will not work correctly for any regex that attempts to match what
CHECK() prints. In these build configurations,
{ASSERT,EXPECT}_DEATH_CHECK() use a match-all regex (""). In other build
configurations, they transparently wrap {ASSERT,EXPECT}_DEATH().

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.

0a4ea0b52d minidump: Change the ownership model.
All minidump objects now own their all of their children, rather than
having them maintain weak pointers and requiring callers to maintain
ownership.

The only weak object in the entire tree now is the “extra memory” added
to a MinidumpMemoryListWriter by its AddExtraMemory() method. Extra
memory aliases objects owned elsewhere in the tree, typically by a
MinidumpThreadWriter as stack memory. Non-“extra” memory added to a
MinidumpMemoryListWriter by its AddMemory() method is strongly owned.

Many objects are now deleted through base pointers, and in those cases,
the base classes now have public virtual destructors. The ultimate base,
MinidumpWritable, is still protected to guard against direct
instantiation and deletion, and thus its destructor does not need to be
virtual.

This updates mini_chromium to eeb3b6a4f020 specifically for that
revision, which includes necessary updates to scoped_ptr. It also picks
