542306626d minidump: Make the MemoryListStream the caboose once again
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.

14138936b5 test: Compare ProcessInfo::Arguments() to main()’s argc/argv on POSIX
Previously on macOS, the test used an OS-specific library function to
recover the original argc and argv. On Linux/Android, it essentially
reimplemented the very code it was testing, which didn’t make for a very
good test. The new approach is to save argc and argv in main() and base
the comparison on that.

f848952e05 Support MINIDUMP_MISC_INFO_5 defined in Windows 10
MINIDUMP_MISC_INFO_5 can carry information about extended XSTATE state
components and the process cookie value.

I made some informed guesses about the precise meanings of some of the
attributes of the XSTATE stuff.

I don’t know what “process cookie” refers to yet. My guess is that it’s
the stack canary value, or something similar. But since this isn’t an
informed guess, I haven’t written it into the documentation.

Crashpad does not yet use either of these features.

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.

dd4859965f Update compat version of winnt.h to 10.0.14393.0 SDK (Windows 10 1607)
This defines PROCESSOR_ARCHITECTURE_ARM64 and
PROCESSOR_ARCHITECTURE_ARM32_ON_WIN64, usable in
MINIDUMP_SYSTEM_INFO::ProcessorArchitecture.

This also defines four new PF_* flags usable in
CPU_INFORMATION::OtherCpuInfo::ProcessorFeatures.

Definitions are provided in compat/non_win, and #ifdef-guarded
definitions in compat/win for compatibility with Windows SDKs older than
Chrome’s minimum requirement.

PROCESSOR_ARCHITECTURE_ARM64 means the same thing that Breakpad used the
value 0x8003 for. At this point, Crashpad aims to use the
officially-defined constant. In the minidump_extensions.h
MinidumpCPUArchitecture enum, 0x8003 remains present and documented as
deprecated to discourage reuse of that constant for another purpose.

acabe35928 doc: Fix all Doxygen warnings, cleaning up some generated documentation
This makes Doxygen’s output more actionable by setting QUIET = YES to
suppress verbose progress spew, and WARN_IF_UNDOCUMENTED = NO to prevent
warnings for undocumented classes and members from being generated. The
latter is too noisy, producing 721 warnings in the current codebase.

The remaining warnings produced by Doxygen were useful and actionable.
They fell into two categories: abuses of Doxygen’s markup syntax, and
missing (or misspelled) parameter documentation. In a small number of
cases, pass-through parameters had intentionally been left undocumented.
In these cases, they are now given blank \param descriptions. This is
not optimal, but there doesn’t appear to be any other way to tell
Doxygen to allow a single parameter to be undocumented.

Some tricky Doxygen errors were resolved by asking it to not enter
directiores that we do not provide documentation in (such as the
“on-platform” compat directories, compat/mac and compat/win, as well as
compat/non_cxx11_lib) while allowing it to enter the
“off-platform” directories that we do document (compat/non_mac and
compat/non_win).

A Doxygen run (doc/support/generate_doxygen.sh) now produces no output
at all. It would produce warnings if any were triggered.

Not directly related, but still relevant to documentation,
doc/support/generate.sh is updated to remove temporary removals of
now-extinct files and directories. doc/appengine/README is updated so
that a consistent path to “goapp” is used throughout the file.

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,

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.

all test-related targets are moved into their own first-class .gyp

d5ddd14ee1 Improve map insertion operations.
Add MapInsertOrReplace<>() to insert a key-value pair into a map if the
key is not already present, or replace the existing value for key if the
key is present. The original value can optionally be returned to the
caller in this case.

Map insertions now use either MapInsertOrReplace<>() or
std::map<>::insert() directly.

Use MapInsertOrReplace<>() when the map should be updated to contain a
mapping from a key to a value regardless of whether the key is already
present.

Use std::map<>::insert() to insert a mapping from a key to a value
without replacing any existing mapping from a key, if present. If it is
important to know whether an existing mapping from a key was present,
use the returned std::pair<>.second. If it is important to know the
existing value, use the returned std::pair<>.first->second.

This change has a slight positive impact on performance.

6bf80c3e48 Add MinidumpCrashpadInfo::report_id.
Now that Chrome’s about:crashes displays the crash report UUID, I wanted
to add it to the minidump. In the future, we may be able to index these
on the server. This will also help identify dumps that correspond to the
same event once we’re equipped to convert between different formats.

Ideally, this new field is populated with the same UUID used locally in
the crash report database. To make this work,
CrashReportDatabase::NewReport must carry the UUID. This was actually
part of CrashReportDatabaseWin’s private extension to NewReport, so that
extension subclass can now be cleaned up.

94f7f9eeb2 MinidumpCrashpadInfo: the default constructor should zero-initialize.
This regressed in 359bdd86225c when a non-POD UUID data member was added
to MinidumpCrashpadInfo, which made MinidumpCrashpadInfo non-POD. This
problem seems to have affected MinidumpModuleCodeViewRecordPDB70 since
it was added, but it is not likely to have caused any problems there
because that structure never appears without having all of its members
populated. By comparison, MinidumpCrashpadInfo may be sparsely
populated.

This caused 4 of the 5 MinidumpCrashpadInfoWriter tests to fail on
Windows.

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().

In Chromium, many targets are built, sharing a single output directory.
Collisions are likely. When integrating Crashpad into Chromium, the
ui/snapshot library and Crashpad’s snapshot library were found to
conflict.

This change gives most Crashpad targets a “crashpad_” prefix to avoid
conflicts. All library and test targets are given a target_name with
this prefix. Existing tools are not likely to conflict with anything
else and are not given a prefix.

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.

Some annotations will exist at a broader scope than per-module, which is
the only place that annotations can currently be stored. The product
name and version are not under the control of any module, but are
established when the first Crashpad client establishes a handler. These
annotations will be stored in a minidump’s MinidumpCrashpadInfo
structure, which applies to the entire minidump.

Within the snapshot interface, this data is carried within the
“process” snapshot because it is the top-level structure in that family.
Note that the data may not correspond directly with a process, however.

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

5906513e30 MinidumpContext: fix some problems in AMD64 (x86_64) context enums.
This fixes a sloppy compliation error: “Redefinition of enumerator
'kMinidumpContextX86Xstate'”. It also fixes CONTEXT_FULL, which should
contain floating-point registers but not segment registers unlike the
its 32-bit x86 equivalent.

Some comments are revised to provide better, um, context.

cb2288d174 Add MinidumpContext (X86 and AMD64 variants) and their writers.
These are fairly simple classes and it’s not valuable to test them
individually. They will be tested as part of MinidumpThreadWriter and
MinidumpExceptionWriter.

9168ba47ac Fix minidump_module_writer_test 32-bit x86 build.
time_t is a typedef for long on Mac OS X. In 32-bit x86 (ILP32), long is
a signed 32-bit quantity, and its range does not contain the range of
uint32_t, used to store times in time_t fashion in minidump files. A
cast is necessary to make these EXPECT_* macros do the right thing. This
is not a problem in x86_64 (LP64) where long is a signed 64-bit
quantity, which does contain the range of uint32_t.

clang’s error was “error: comparison of integers of different signs:
'const long' and 'const unsigned int' [-Werror,-Wsign-compare]”
