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).

at all. It would produce warnings if any were triggered.

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.

This defines the global (per-module) CrashpadInfo structure properly on

This change is sufficient to successfully build crashpad_client as a

Second follow up to https://chromium-review.googlesource.com/c/400015/
The ideal would be that if we fail to start the handler, then we don't
end up passing through our unhandled exception filter at all.
In the case of the non-initial client (i.e. renderers) we can do this by
not setting our UnhandledExceptionFilter until after we know we've
connected successfully (because those connections are synchronous from
its point of view). We also change WaitForNamedPipe in the connection
message to block forever, so as long as the precreated pipe exists,
they'll wait to connect. After the initial client has passed the server
side of that pipe to the handler, the handler has the only handle to it.
So, if the handler has disappeared for whatever reason, pipe-connecting
clients will fail with FILE_NOT_FOUND, and will not stick around in the
connection loop. This means non-initial clients do not need additional
logic to avoid getting stuck in our UnhandledExceptionFilter.
For the initial client, it would be ideal to avoid passing through our
UEF too, but none of the 3 options are great:
1. Block until we find out if we started, and then install the filter.
We don't want to do that, because we don't want to wait.
2. Restore the old filter if it turns out we failed to start. We can't
do that because Chrome disables ::SetUnhandledExceptionFilter()
immediately after StartHandler/SetHandlerIPCPipe returns.
3. Don't install our filter until we've successfully started. We don't
want to do that because we'd miss early crashes, negating the benefit
of deferred startup.
So, we do need to pass through our UnhandledExceptionFilter. I don't
want more Win32 API calls during the vulnerable filter function. So, at
any point during async startup where there's a failure, set a global
atomic that allows the filter function to abort without trying to signal
a handler that's known to not exist.
One further improvement we might want to look at is unexpected
termination of the handler (as opposed to a failure to start) which
would still result in a useless Sleep(60s). This isn't new behaviour,
but now we have a clear thing to do if we detect the handler is gone.
(Also a missing DWORD/size_t cast for the _x64 bots.)

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.
