bff3594594 fuchsia: Update includes for new fdio header location
Also includes a gtest roll, which includes a change in gtest to do the
same thing. This also removes the link against launchpad which is no
longer necessary, and will be removed from the SDK soon.

a279673974 fuchsia: Implement execvp() equivalent for run_with_crashpad
There's no implementation of execvp() on Fuchsia, so attempt to emulate
it in `run_with_crashpad` by using launchpad. Failures are mapped to
exit codes similar to what the execvp() path would return for missing
binary, and other non-subprocess errors.

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.

00e6bd0887 fuchsia: Get 'all' to build
Adds a zlib build file for when building standalone (rather than reusing
Chromium's, though the code still Chromium's patched copy). The separate
build file avoids including the code for minizip and other support
targets (instead, only the main libzlib.a static_library is defined).
The other libraries and executables won't build in the Crashpad repo, so
having a local build file means that all targets defined in the GN build
are buildable.

generate_dump is passing an invalid handle to ProcessSnapshotFuchsia as
there's not yet any utility to convert a pid to a handle. But that's no
great loss, because ProcessSnapshotFuchsia doesn't do anything itself
yet.

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.

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.

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.

00b6442752 Make file_io reads more rational and predictable
ReadFile() attempted to continue reading after a short read. In most
cases, this is fine. However, ReadFile() would keep trying to fill a
partially-filled buffer until experiencing a 0-length read(), signaling
end-of-file. For certain weird file descriptors like terminal input, EOF
is an ephemeral condition, and attempting to read beyond EOF doesn’t
actually return 0 (EOF) provided that they remain open, it will block
waiting for more input. Consequently, ReadFile() and anything based on
ReadFile() had an undocumented and quirky interface, which was that any
short read that it returned (not an underlying short read) actually
indicated EOF.

This facet of ReadFile() was unexpected, so it’s being removed. The new
behavior is that ReadFile() will return an underlying short read. The
behavior of FileReaderInterface::Read() is updated in accordance with
this change.

Upon experiencing a short read, the caller can determine the best
action. Most callers were already prepared for this behavior. Outside of
util/file, only crashpad_database_util properly implemented EOF
detection according to previous semantics, and adapting it to new
semantics is trivial.

Callers who require an exact-length read can use the new
ReadFileExactly(), or the newly renamed LoggingReadFileExactly() or
CheckedReadFileExactly(). These functions will retry following a short
read. The renamed functions were previously called LoggingReadFile() and
CheckedReadFile(), but those names implied that they were simply
wrapping ReadFile(), which is not the case. They wrapped ReadFile() and
further, insisted on a full read. Since ReadFile()’s semantics are now
changing but these functions’ are not, they’re now even more distinct
from ReadFile(), and must be renamed to avoid confusion.

--set-last-upload-attempt-time=now is a new supported (and documented)

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.

0c41b15496 Convert AsciiDoc documentation to Markdown
Most of the world, including the Chromium universe, seems to be
standardizing on Markdown for documentation. Markdown provides the
benefit of automatic rendering on Gitiles (Gerrit), and on GitHub
mirrors as well. Crashpad should fit in with its surroundings.

There are two quirks that I was unable to resolve.

 - Markdown does not allow **emphasis** within a ```code fence```
   region. In blocks showing interactive examples, the AsciiDoc
   documentation used this to highlight what the user was expected to
   type.
 - Markdown does not have a “definition list” (<dl>). This would have
   been nice in man pages for the Options and Exit Status sections.
   In its place, I used unnumbered lists. This is a little ugly, but
   it’s not the end of the world.

The new Markdown-formatted documentation is largely identical to the
AsciiDoc that it replaces. Minor editorial revisions were made.
References to Mac OS X now mention macOS, and tool man pages describing
tools that that access task ports now mention System Integrity
Protection (SIP).

The AppEngine-based https://crashpad.chromium.org/ app in doc/appengine
is still necessary to serve Doxygen-generated documentation. This app is
updated to redirect existing generated-HTML URLs to Gitiles’ automatic
Markdown rendering.

Scripts in doc/support are updated to adapt to this change. All AsciiDoc
support files in doc/support have been removed.

2d87606bb5 win: Start crashpad_handler by inheriting connection data to it
Previously, StartHandler() launched the handler process, then connected
over a pipe to register for crash handling. Instead, the initial client
can create and inherit handles to the handler and pass those handle
values and other data (addresses, etc.) on the command line.

This should improve startup time as there's no need to synchronize with
the process at startup, and allows avoiding a call to CreateProcess()
directly in StartHandler(), which is important for registration for
crash reporting from DllMain().

Incidentally adds new utility functions for string/number conversion and
string splitting.

Note: API change; UseHandler() is removed for all platforms.

Because DumpAndCrashTargetProcess() suspends the process, the thread

one in the thread snapshots. Compensate for this when we detect this

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.

This more-natural spelling doesn’t require Crashpad developers to have

6c0d42ce9d Mach port scopers should use get() instead of type conversion operators
In https://codereview.chromium.org/1411523006, the Mach port scopers are
becoming better ScopedGenerics and are losing the type conversion
operators in the process. This is needed to adapt to that change. get()
is ugly, but being explicit about conversion isn’t a bad thing, and
these scopers will gain functionality such as Pass() as part of the
switch.

As a bonus, some would-be uses of get() to check for valid port rights
are becoming a more descriptive is_valid().

I’ve accidentally created Crashpad databases when running
crashpad_database_util by mistyping the argument to --database. Typical
users of crashpad_database_util probably don’t want the database to be

This adds a new --create option to crashpad_database_util that is

not be created if it does not already exist.

5f7eda87a6 mac: Don’t leak send rights from ExceptionPorts::GetExceptionPorts()
ExceptionPorts::GetExceptionPorts() returned a
std::vector<ExceptionPorts::ExceptionHandler>, which contained send
rights to Mach ports. The interface required callers to assume ownership
of each send right contained within the vector. This was cumbersome and
error-prone, and despite the care taken in Crashpad, port right leaks
did occur:

 - SimulateCrash() didn’t make any attempt to release these resources at
   all.
 - Neither did crashpad_util_test ExceptionPorts.HostExceptionPorts,
   which also reused a vector.

This replaces the vector with the interface-compatible (as far as
necessary) ExceptionPorts::ExceptionHandlerVector, which deallocates
collected port rights on destruction or clear().

9086d25ce8 Don’t trigger EXC_CORPSE_NOTIFY on OS X 10.11
CrashReportExceptionHandler::CatchMachException() must always set a
valid new_state. Failing to do so appears to trigger corpse generation
on OS X 10.11. This is addressed by calling ExcServerCopyState().
Previously, this was not done for exceptions forwarded to the user
ReportCrash, under the apparent mistaken assumption that ReportCrash
would do it. However, ReportCrash is given copies of out-parameters like
new_state to explicitly prevent it from influencing Crashpad’s returned
state.

ExcServerSuccessfulReturnValue() must not return MACH_RCV_PORT_DIED for
an EXC_CRASH handler on OS X 10.11. This appears to trigger corpse
generation. This is addressed by always returning KERN_SUCCESS from
EXC_CRASH handlers on OS X 10.11.

This also adds generic EXC_CORPSE_NOTIFY support throughout Crashpad.
The crashpad_handler does not listen for this exception type, but it is
now possible to work with this exception type using tools like
exception_port_tool and catch_exception_tool.
