Mark Mentovai 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.

run_with_crashpad(1)

Name

run_with_crashpad—Run a program with a Crashpad exception handler

Synopsis

run_with_crashpad [OPTION…] COMMAND [ARG…]

Description

Starts a Crashpad exception handler server such as crashpad_handler(8) and becomes its client, setting an exception port referencing the handler. Then, executes COMMAND along with any arguments specified (ARG…) with the new exception port in effect.

The exception port is configured to receive exceptions of type EXC_CRASH, EXC_RESOURCE, and EXC_GUARD. The exception behavior is configured as EXCEPTION_STATE_IDENTITY | MACH_EXCEPTION_CODES. The thread state flavor is set to MACHINE_THREAD_STATE.

Programs that use the Crashpad client library directly will not normally use this tool. This tool exists to allow programs that are unaware of Crashpad to be run with a Crashpad exception handler.

Options

  • -h, --handler=HANDLER

    Invoke 'HANDLER' as the Crashpad handler program instead of the default, crashpad_handler.

  • --annotation=KEY=VALUE

    Passed to the Crashpad handler program as an --annotation argument.

  • --database=PATH

    Passed to the Crashpad handler program as its --database argument.

  • --url=URL

    Passed to the Crashpad handler program as its --url argument.

  • -a, --argument=ARGUMENT

    Invokes the Crashpad handler program with ARGUMENT as one of its arguments. This option may appear zero, one, or more times. If this program has a specific option such as --database matching the desired Crashpad handler program option, the specific option should be used in preference to --argument. Regardless of this options presence, the handler will always be invoked with the necessary arguments to perform a handshake.

  • --help

    Display help and exit.

  • --version

    Output version information and exit.

Examples

Starts a Crashpad exception handler server by its default name, crashpad_handler, and runs a program with this handler in effect.

$ run_with_crashpad --database=/tmp/crashpad_database crasher
Illegal instruction: 4

Starts a Crashpad exception handler server at a nonstandard path, and runs exception_port_tool(1) to show the task-level exception ports.

$ run_with_crashpad --handler=/tmp/crashpad_handler \
      --database=/tmp/crashpad_database exception_port_tool \
      --show-task
task exception port 0, mask 0x1c00 (CRASH|RESOURCE|GUARD), port 0x30b, behavior 0x80000003 (STATE_IDENTITY|MACH), flavor 7 (THREAD)

Exit Status

  • 0

    Success.

  • 125

    Failure, with a message printed to the standard error stream.

  • 126

    The program specified by 'COMMAND' was found, but could not be invoked.

  • 127

    The program specified by 'COMMAND' could not be found.
