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.

= Developing Crashpad
|
|
||||||
|
|
||||||
== Status
|
|
||||||
|
|
||||||
link:status.html[Project status] information has moved to its own page.
|
|
||||||
|
|
||||||
== Introduction
|
|
||||||
|
|
||||||
Crashpad is a https://dev.chromium.org/Home[Chromium project]. Most of
|
|
||||||
its development practices follow Chromium’s. In order to function on its
|
|
||||||
own in other projects, Crashpad uses
|
|
||||||
https://chromium.googlesource.com/chromium/mini_chromium/[mini_chromium],
|
|
||||||
a small, self-contained library that provides many of Chromium’s useful
|
|
||||||
low-level base routines.
|
|
||||||
https://chromium.googlesource.com/chromium/mini_chromium/+/master/README[mini_chromium’s
|
|
||||||
README] provides more detail.
|
|
||||||
|
|
||||||
== Prerequisites
|
|
||||||
|
|
||||||
To develop Crashpad, the following tools are necessary, and must be
|
|
||||||
present in the `$PATH` environment variable:
|
|
||||||
|
|
||||||
* Chromium’s
|
|
||||||
https://dev.chromium.org/developers/how-tos/depottools[depot_tools].
|
|
||||||
* https://git-scm.com/[Git]. This is provided by Xcode on Mac OS X and by
|
|
||||||
depot_tools on Windows.
|
|
||||||
* https://www.python.org/[Python]. This is provided by the operating system on
|
|
||||||
Mac OS X, and by depot_tools on Windows.
|
|
||||||
* Appropriate development tools. For Mac OS X, this is
|
|
||||||
https://developer.apple.com/xcode/[Xcode], and for Windows, it’s
|
|
||||||
https://www.visualstudio.com/[Visual Studio].
|
|
||||||
|
|
||||||
== Getting the Source Code
|
|
||||||
|
|
||||||
The main source code repository is a Git repository hosted at
|
|
||||||
https://chromium.googlesource.com/crashpad/crashpad. Although it is possible to
|
|
||||||
check out this repository directly with `git clone`, Crashpad’s dependencies are
|
|
||||||
managed by
|
|
||||||
https://dev.chromium.org/developers/how-tos/depottools#TOC-gclient[`gclient`]
|
|
||||||
instead of Git submodules, so to work on Crashpad, it is best to use `fetch` to
|
|
||||||
get the source code.
|
|
||||||
|
|
||||||
`fetch` and `gclient` are part of the
|
|
||||||
https://dev.chromium.org/developers/how-tos/depottools[depot_tools]. There’s no
|
|
||||||
need to install them separately.
|
|
||||||
|
|
||||||
=== Initial Checkout
|
|
||||||
|
|
||||||
[subs="verbatim,quotes"]
|
|
||||||
----
|
|
||||||
$ *mkdir \~/crashpad*
|
|
||||||
$ *cd ~/crashpad*
|
|
||||||
$ *fetch crashpad*
|
|
||||||
----
|
|
||||||
|
|
||||||
`fetch crashpad` performs the initial `git clone` and `gclient sync`,
|
|
||||||
establishing a fully-functional local checkout.
|
|
||||||
|
|
||||||
=== Subsequent Checkouts
|
|
||||||
|
|
||||||
[subs="verbatim,quotes"]
|
|
||||||
----
|
|
||||||
$ *cd ~/crashpad/crashpad*
|
|
||||||
$ *git pull -r*
|
|
||||||
$ *gclient sync*
|
|
||||||
----
|
|
||||||
|
|
||||||
== Building
|
|
||||||
|
|
||||||
Crashpad uses https://gyp.gsrc.io/[GYP] to generate
|
|
||||||
https://ninja-build.org/[Ninja] build files. The build is described by `.gyp`
|
|
||||||
files throughout the Crashpad source code tree. The `build/gyp_crashpad.py`
|
|
||||||
script runs GYP properly for Crashpad, and is also called when you run `fetch
|
|
||||||
crashpad`, `gclient sync`, or `gclient runhooks`.
|
|
||||||
|
|
||||||
The Ninja build files and build output are in the `out` directory. Both debug-
|
|
||||||
and release-mode configurations are available. The examples below show the debug
|
|
||||||
configuration. To build and test the release configuration, substitute `Release`
|
|
||||||
for `Debug`.
|
|
||||||
|
|
||||||
[subs="verbatim,quotes"]
|
|
||||||
----
|
|
||||||
$ *cd ~/crashpad/crashpad*
|
|
||||||
$ *ninja -C out/Debug*
|
|
||||||
----
|
|
||||||
|
|
||||||
Ninja is part of the
|
|
||||||
https://dev.chromium.org/developers/how-tos/depottools[depot_tools]. There’s no
|
|
||||||
need to install it separately.
|
|
||||||
|
|
||||||
=== Android
|
|
||||||
|
|
||||||
Crashpad’s Android port is in its early stages. This build relies on
|
|
||||||
cross-compilation. It’s possible to develop Crashpad for Android on any platform
|
|
||||||
that the https://developer.android.com/ndk/[Android NDK (Native Development
|
|
||||||
Kit)] runs on.
|
|
||||||
|
|
||||||
If it’s not already present on your system,
|
|
||||||
https://developer.android.com/ndk/downloads/[download the NDK package for your
|
|
||||||
system] and expand it to a suitable location. These instructions assume that
|
|
||||||
it’s been expanded to `~/android-ndk-r13`.
|
|
||||||
|
|
||||||
To build Crashpad, portions of the NDK must be reassembled into a
|
|
||||||
https://developer.android.com/ndk/guides/standalone_toolchain.html[standalone
|
|
||||||
toolchain]. This is a repackaged subset of the NDK suitable for cross-compiling
|
|
||||||
for a single Android architecture (such as `arm`, `arm64`, `x86`, and `x86_64`)
|
|
||||||
targeting a specific
|
|
||||||
https://source.android.com/source/build-numbers.html[Android API level]. The
|
|
||||||
standalone toolchain only needs to be built from the NDK one time for each set
|
|
||||||
of options desired. To build a standalone toolchain targeting 64-bit ARM and API
|
|
||||||
level 21 (Android 5.0 “Lollipop”), run:
|
|
||||||
|
|
||||||
[subs="verbatim,quotes"]
|
|
||||||
----
|
|
||||||
$ *cd ~*
|
|
||||||
$ *python android-ndk-r13/build/tools/make_standalone_toolchain.py \
|
|
||||||
--arch=arm64 --api=21 --install-dir=android-ndk-r13_arm64_api21*
|
|
||||||
----
|
|
||||||
|
|
||||||
Note that Chrome uses Android API level 21 for 64-bit platforms and 16 for
|
|
||||||
32-bit platforms. See Chrome’s
|
|
||||||
https://chromium.googlesource.com/chromium/src/+/master/build/config/android/config.gni[`build/config/android/config.gni`]
|
|
||||||
which sets `_android_api_level` and `_android64_api_level`.
|
|
||||||
|
|
||||||
To configure a Crashpad build for Android using this standalone toolchain,
|
|
||||||
set several environment variables directing the build to the standalone
|
|
||||||
toolchain, along with GYP options to identify an Android build. This must be
|
|
||||||
done after any `gclient sync`, or instead of any `gclient runhooks` operation.
|
|
||||||
The environment variables only need to be set for this `gyp_crashpad.py`
|
|
||||||
invocation, and need not be permanent.

== Testing
|
|
||||||
|
|
||||||
Crashpad uses https://github.com/google/googletest/[Google Test] as its
|
|
||||||
unit-testing framework, and some tests use
|
|
||||||
https://github.com/google/googletest/tree/master/googlemock/[Google Mock] as
|
|
||||||
well. Its tests are currently split up into several test executables, each
|
|
||||||
dedicated to testing a different component. This may change in the future. After
|
|
||||||
a successful build, the test executables will be found at
|
|
||||||
`out/Debug/crashpad_*_test`.
|
|
||||||
|
|
||||||
[subs="verbatim,quotes"]
|
|
||||||

|
|
||||||
$ *out/Debug/crashpad_util_test*
|
|
||||||
----
|
|
||||||
|
|
||||||
A script is provided to run all of Crashpad’s tests. It accepts a single
|
|
||||||
argument that tells it which configuration to test.

=== Android
|
|
||||||
|
|
||||||
To test on Android, use
|
|
||||||
https://developer.android.com/studio/command-line/adb.html[ADB (Android Debug
|
|
||||||
Bridge)] to `adb push` test executables and test data to a device or emulator,
|
|
||||||
then use `adb shell` to get a shell to run the test executables from. ADB is
|
|
||||||
part of the https://developer.android.com/sdk/[Android SDK]. Note that it is
|
|
||||||
sufficient to install just the command-line tools. The entire Android Studio IDE

is not necessary to obtain ADB.
|
|

|
|
||||||
This example runs `crashpad_test_test` on a device. This test executable has a
|
|
||||||
run-time dependency on a second executable and a test data file, which are also
|
|
||||||
transferred to the device prior to running the test.

== Contributing
|
|
||||||
|
|
||||||
Crashpad’s contribution process is very similar to
|
|
||||||
https://dev.chromium.org/developers/contributing-code[Chromium’s contribution
|
|
||||||
process].
|
|
||||||
|
|
||||||
=== Code Review
|
|
||||||
|
|
||||||
A code review must be conducted for every change to Crashpad’s source code. Code
|
|
||||||
review is conducted on https://chromium-review.googlesource.com/[Chromium’s
|
|
||||||
Gerrit] system, and all code reviews must be sent to an appropriate reviewer,
|
|
||||||
with a Cc sent to
|
|
||||||
https://groups.google.com/a/chromium.org/group/crashpad-dev[crashpad-dev]. The
|
|
||||||
https://chromium.googlesource.com/crashpad/crashpad/+/master/codereview.settings[`codereview.settings`]
|
|
||||||
file specifies this environment to `git-cl`.
|
|
||||||
|
|
||||||
`git-cl` is part of the
|
|
||||||
https://dev.chromium.org/developers/how-tos/depottools[depot_tools]. There’s no
|
|
||||||
need to install it separately.
|
|
||||||
|
|
||||||

|
|
||||||
----
|
|
||||||
$ *cd ~/crashpad/crashpad*
|
|
||||||
$ *git checkout -b work_branch origin/master*
|
|
||||||
_…do some work…_
|
|
||||||
$ *git add …*
|
|
||||||
$ *git commit*
|
|
||||||
$ *git cl upload*
|
|
||||||
----
|
|
||||||
|
|
||||||
The https://polygerrit.appspot.com/[PolyGerrit interface] to Gerrit, undergoing
|
|
||||||
active development, is recommended. To switch from the classic GWT-based Gerrit
|
|
||||||
UI to PolyGerrit, click the PolyGerrit link in a Gerrit review page’s footer.
|
|
||||||
|
|
||||||
Uploading a patch to Gerrit does not automatically request a review. You must
|
|
||||||
select a reviewer on the Gerrit review page after running `git cl upload`. This
|
|
||||||
action notifies your reviewer of the code review request. If you have lost track
|
|
||||||
of the review page, `git cl issue` will remind you of its URL. Alternatively,
|
|
||||||
you can request review when uploading to Gerrit by using `git cl upload
|
|
||||||
--send-mail`.
|
|
||||||
|
|
||||||
Git branches maintain their association with Gerrit reviews, so if you need to
|
|
||||||
make changes based on review feedback, you can do so on the correct Git branch,
|
|
||||||
committing your changes locally with `git commit`. You can then upload a new
|
|
||||||
patch set with `git cl upload` and let your reviewer know you’ve addressed the
|
|
||||||
feedback.
|
|
||||||
|
|
||||||
=== Landing Changes
|
|
||||||
|
|
||||||
After code review is complete and “Code-Review: +1” has been received from all
|
|
||||||
reviewers, project members can commit the patch themselves:
|
|
||||||
|
|
||||||
[subs="verbatim,quotes"]
|
|
||||||
----
|
|
||||||
$ *cd ~/crashpad/crashpad*
|
|
||||||
$ *git checkout work_branch*
|
|
||||||
$ *git cl land*
|
|
||||||
----
|
|
||||||
|
|
||||||
Alternatively, patches can be committed by clicking the “Submit” button in the
|
|
||||||
Gerrit UI.
|
|
||||||
|
|
||||||
Crashpad does not currently have a
|
|
||||||
https://dev.chromium.org/developers/testing/commit-queue[commit queue], so
|
|
||||||
contributors who are not project members will have to ask a project member to
|
|
||||||
commit the patch for them. Project members can commit changes on behalf of
|
|
||||||
external contributors by clicking the “Submit” button in the Gerrit UI.
|
|
||||||
|
|
||||||
=== External Contributions
|
|
||||||
|
|
||||||
Copyright holders must complete the
|

== Buildbot
|
|
||||||
|
|
||||||
The https://build.chromium.org/p/client.crashpad/[Crashpad Buildbot] performs
|
|
||||||
automated builds and tests of Crashpad. Before checking out or updating the
|
|
||||||
Crashpad source code, and after checking in a new change, it is prudent to check
|
|
||||||
the Buildbot to ensure that “the tree is green.”

# Developing Crashpad
|
||||||
|
|
||||||
|
## Status
|
||||||
|
|
||||||
|
[Project status](status.md) information has moved to its own page.
|
||||||
|
|
||||||
|
## Introduction
|
||||||
|
|
||||||
|
Crashpad is a [Chromium project](https://dev.chromium.org/Home). Most of its
|
||||||
|
development practices follow Chromium’s. In order to function on its own in
|
||||||
|
other projects, Crashpad uses
|
||||||
|
[mini_chromium](https://chromium.googlesource.com/chromium/mini_chromium/), a
|
||||||
|
small, self-contained library that provides many of Chromium’s useful low-level
|
||||||
|
base routines. [mini_chromium’s
|
||||||
|
README](https://chromium.googlesource.com/chromium/mini_chromium/+/master/README)
|
||||||
|
provides more detail.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
To develop Crashpad, the following tools are necessary, and must be
|
||||||
|
present in the `$PATH` environment variable:
|
||||||
|
|
||||||
|
* Chromium’s
|
||||||
|
[depot_tools](https://dev.chromium.org/developers/how-tos/depottools).
|
||||||
|
* [Git](https://git-scm.com/). This is provided by Xcode on macOS and by
|
||||||
|
depot_tools on Windows.
|
||||||
|
* [Python](https://www.python.org/). This is provided by the operating system
|
||||||
|
on macOS, and by depot_tools on Windows.
|
||||||
|
* Appropriate development tools. For macOS, this is
|
||||||
|
[Xcode](https://developer.apple.com/xcode/) and for Windows, it’s [Visual
|
||||||
|
Studio](https://www.visualstudio.com/).
|
||||||
|
|
||||||
|
## Getting the Source Code
|
||||||
|
|
||||||
|
The main source code repository is a Git repository hosted at
|
||||||
|
https://chromium.googlesource.com/crashpad/crashpad. Although it is possible to
|
||||||
|
check out this repository directly with `git clone`, Crashpad’s dependencies are
|
||||||
|
managed by
|
||||||
|
[`gclient`](https://dev.chromium.org/developers/how-tos/depottools#TOC-gclient)
|
||||||
|
instead of Git submodules, so to work on Crashpad, it is best to use `fetch` to
|
||||||
|
get the source code.
|
||||||
|
|
||||||
|
`fetch` and `gclient` are part of the
|
||||||
|
[depot_tools](https://dev.chromium.org/developers/how-tos/depottools). There’s
|
||||||
|
no need to install them separately.
|
||||||
|
|
||||||
|
### Initial Checkout
|
||||||
|
|
||||||
|
```
|
||||||
|
$ mkdir ~/crashpad
|
||||||
|
$ cd ~/crashpad
|
||||||
|
$ fetch crashpad
|
||||||
|
```
|
||||||
|
|
||||||
|
`fetch crashpad` performs the initial `git clone` and `gclient sync`,
|
||||||
|
establishing a fully-functional local checkout.
|
||||||
|
|
||||||
|
### Subsequent Checkouts
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ git pull -r
|
||||||
|
$ gclient sync
|
||||||
|
```
|
||||||
|
|
||||||
|
## Building
|
||||||
|
|
||||||
|
Crashpad uses [GYP](https://gyp.gsrc.io/) to generate
|
||||||
|
[Ninja](https://ninja-build.org/) build files. The build is described by `.gyp`
|
||||||
|
files throughout the Crashpad source code tree. The
|
||||||
|
[`build/gyp_crashpad.py`](https://chromium.googlesource.com/crashpad/crashpad/+/master/build/gyp_crashpad.py)
|
||||||
|
script runs GYP properly for Crashpad, and is also called when you run `fetch
|
||||||
|
crashpad`, `gclient sync`, or `gclient runhooks`.
|
||||||
|
|
||||||
|
The Ninja build files and build output are in the `out` directory. Both debug-
|
||||||
|
and release-mode configurations are available. The examples below show the debug
|
||||||
|
configuration. To build and test the release configuration, substitute `Release`
|
||||||
|
for `Debug`.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ ninja -C out/Debug
|
||||||
|
```
|
||||||
|
|
||||||
|
Ninja is part of the
|
||||||
|
[depot_tools](https://dev.chromium.org/developers/how-tos/depottools). There’s
|
||||||
|
no need to install it separately.
|
||||||
|
|
||||||
|
### Android
|
||||||
|
|
||||||
|
Crashpad’s Android port is in its early stages. This build relies on
|
||||||
|
cross-compilation. It’s possible to develop Crashpad for Android on any platform
|
||||||
|
that the [Android NDK (Native Development
|
||||||
|
Kit)](https://developer.android.com/ndk/) runs on.
|
||||||
|
|
||||||
|
If it’s not already present on your system, [download the NDK package for your
|
||||||
|
system](https://developer.android.com/ndk/downloads/) and expand it to a
|
||||||
|
suitable location. These instructions assume that it’s been expanded to
|
||||||
|
`~/android-ndk-r13`.
|
||||||
|
|
||||||
|
To build Crashpad, portions of the NDK must be reassembled into a [standalone
|
||||||
|
toolchain](https://developer.android.com/ndk/guides/standalone_toolchain.html).
|
||||||
|
This is a repackaged subset of the NDK suitable for cross-compiling for a single
|
||||||
|
Android architecture (such as `arm`, `arm64`, `x86`, and `x86_64`) targeting a
|
||||||
|
specific [Android API
|
||||||
|
level](https://source.android.com/source/build-numbers.html). The standalone
|
||||||
|
toolchain only needs to be built from the NDK one time for each set of options
|
||||||
|
desired. To build a standalone toolchain targeting 64-bit ARM and API level 21
|
||||||
|
(Android 5.0 “Lollipop”), run:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~
|
||||||
|
$ python android-ndk-r13/build/tools/make_standalone_toolchain.py \
|
||||||
|
--arch=arm64 --api=21 --install-dir=android-ndk-r13_arm64_api21
|
||||||
|
```
|
||||||
|
|
||||||
|
Note that Chrome uses Android API level 21 for 64-bit platforms and 16 for
|
||||||
|
32-bit platforms. See Chrome’s
|
||||||
|
[`build/config/android/config.gni`](https://chromium.googlesource.com/chromium/src/+/master/build/config/android/config.gni)
|
||||||
|
which sets `_android_api_level` and `_android64_api_level`.
|
||||||
|
|
||||||
|
To configure a Crashpad build for Android using this standalone toolchain, set
|
||||||
|
several environment variables directing the build to the standalone toolchain,
|
||||||
|
along with GYP options to identify an Android build. This must be done after any
|
||||||
|
`gclient sync`, or instead of any `gclient runhooks` operation. The environment
|
||||||
|
variables only need to be set for this `gyp_crashpad.py` invocation, and need
|
||||||
|
not be permanent.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ CC_target=~/android-ndk-r13_arm64_api21/bin/clang \
|
||||||
|
CXX_target=~/android-ndk-r13_arm64_api21/bin/clang++ \
|
||||||
|
AR_target=~/android-ndk-r13_arm64_api21/bin/aarch64-linux-android-ar \
|
||||||
|
NM_target=~/android-ndk-r13_arm64_api21/bin/aarch64-linux-android-nm \
|
||||||
|
READELF_target=~/android-ndk-r13_arm64_api21/bin/aarch64-linux-android-readelf \
|
||||||
|
python build/gyp_crashpad.py \
|
||||||
|
-DOS=android -Dtarget_arch=arm64 -Dclang=1 \
|
||||||
|
--generator-output=out_android_arm64_api21 -f ninja-android
|
||||||
|
```
|
||||||
|
|
||||||
|
Target “triplets” to use for `ar`, `nm`, and `readelf` are:
|
||||||
|
|
||||||
|
| Architecture | Target “triplet” |
|
||||||
|
|:-------------|:------------------------|
|
||||||
|
| `arm` | `arm-linux-androideabi` |
|
||||||
|
| `arm64` | `aarch64-linux-android` |
|
||||||
|
| `x86` | `i686-linux-android` |
|
||||||
|
| `x86_64` | `x86_64-linux-android` |
|
||||||
|
|
||||||
|
The port is incomplete, but targets known to be working include `crashpad_util`,
|
||||||
|
`crashpad_test`, and `crashpad_test_test`. This list will grow over time. To
|
||||||
|
build, direct `ninja` to the specific `out` directory chosen by
|
||||||
|
`--generator-output` above.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ ninja -C out_android_arm64_api21/out/Debug crashpad_test_test
|
||||||
|
```
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
Crashpad uses [Google Test](https://github.com/google/googletest/) as its
|
||||||
|
unit-testing framework, and some tests use [Google
|
||||||
|
Mock](https://github.com/google/googletest/tree/master/googlemock/) as well. Its
|
||||||
|
tests are currently split up into several test executables, each dedicated to
|
||||||
|
testing a different component. This may change in the future. After a successful
|
||||||
|
build, the test executables will be found at `out/Debug/crashpad_*_test`.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ out/Debug/crashpad_minidump_test
|
||||||
|
$ out/Debug/crashpad_util_test
|
||||||
|
```
|
||||||
|
|
||||||
|
A script is provided to run all of Crashpad’s tests. It accepts a single
|
||||||
|
argument that tells it which configuration to test.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ python build/run_tests.py Debug
|
||||||
|
```
|
||||||
|
|
||||||
|
### Android
|
||||||
|
|
||||||
|
To test on Android, use [ADB (Android Debug
|
||||||
|
Bridge)](https://developer.android.com/studio/command-line/adb.html) to `adb
|
||||||
|
push` test executables and test data to a device or emulator, then use `adb
|
||||||
|
shell` to get a shell to run the test executables from. ADB is part of the
|
||||||
|
[Android SDK](https://developer.android.com/sdk/). Note that it is sufficient to
|
||||||
|
install just the command-line tools. The entire Android Studio IDE is not
|
||||||
|
necessary to obtain ADB.
|
||||||
|
|
||||||
|
This example runs `crashpad_test_test` on a device. This test executable has a
|
||||||
|
run-time dependency on a second executable and a test data file, which are also
|
||||||
|
transferred to the device prior to running the test.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ adb push out_android_arm64_api21/out/Debug/crashpad_test_test /data/local/tmp/
|
||||||
|
[100%] /data/local/tmp/crashpad_test_test
|
||||||
|
$ adb push \
|
||||||
|
out_android_arm64_api21/out/Debug/crashpad_test_test_multiprocess_exec_test_child \
|
||||||
|
/data/local/tmp/
|
||||||
|
[100%] /data/local/tmp/crashpad_test_test_multiprocess_exec_test_child
|
||||||
|
$ adb shell mkdir -p /data/local/tmp/crashpad_test_data_root/test
|
||||||
|
$ adb push test/paths_test_data_root.txt \
|
||||||
|
/data/local/tmp/crashpad_test_data_root/test/
|
||||||
|
[100%] /data/local/tmp/crashpad_test_data_root/test/paths_test_data_root.txt
|
||||||
|
$ adb shell
|
||||||
|
device:/ $ cd /data/local/tmp
|
||||||
|
device:/data/local/tmp $ CRASHPAD_TEST_DATA_ROOT=crashpad_test_data_root \
|
||||||
|
./crashpad_test_test
|
||||||
|
```
|
||||||
|
|
||||||
|
## Contributing
|
||||||
|
|
||||||
|
Crashpad’s contribution process is very similar to [Chromium’s contribution
|
||||||
|
process](https://dev.chromium.org/developers/contributing-code).
|
||||||
|
|
||||||
|
### Code Review
|
||||||
|
|
||||||
|
A code review must be conducted for every change to Crashpad’s source code. Code
|
||||||
|
review is conducted on [Chromium’s
|
||||||
|
Gerrit](https://chromium-review.googlesource.com/) system, and all code reviews
|
||||||
|
must be sent to an appropriate reviewer, with a Cc sent to
|
||||||
|
[crashpad-dev](https://groups.google.com/a/chromium.org/group/crashpad-dev). The
|
||||||
|
[`codereview.settings`](https://chromium.googlesource.com/crashpad/crashpad/+/master/codereview.settings)
|
||||||
|
file specifies this environment to `git-cl`.
|
||||||
|
|
||||||
|
`git-cl` is part of the
|
||||||
|
[depot_tools](https://dev.chromium.org/developers/how-tos/depottools). There’s
|
||||||
|
no need to install it separately.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ git checkout -b work_branch origin/master
|
||||||
|
…do some work…
|
||||||
|
$ git add …
|
||||||
|
$ git commit
|
||||||
|
$ git cl upload
|
||||||
|
```
|
||||||
|
|
||||||
|
The [PolyGerrit interface](https://polygerrit.appspot.com/) to Gerrit,
|
||||||
|
undergoing active development, is recommended. To switch from the classic
|
||||||
|
GWT-based Gerrit UI to PolyGerrit, click the PolyGerrit link in a Gerrit review
|
||||||
|
page’s footer.
|
||||||
|
|
||||||
|
Uploading a patch to Gerrit does not automatically request a review. You must
|
||||||
|
select a reviewer on the Gerrit review page after running `git cl upload`. This
|
||||||
|
action notifies your reviewer of the code review request. If you have lost track
|
||||||
|
of the review page, `git cl issue` will remind you of its URL. Alternatively,
|
||||||
|
you can request review when uploading to Gerrit by using `git cl upload
|
||||||
|
--send-mail`.
|
||||||
|
|
||||||
|
Git branches maintain their association with Gerrit reviews, so if you need to
|
||||||
|
make changes based on review feedback, you can do so on the correct Git branch,
|
||||||
|
committing your changes locally with `git commit`. You can then upload a new
|
||||||
|
patch set with `git cl upload` and let your reviewer know you’ve addressed the
|
||||||
|
feedback.
|
||||||
|
|
||||||
|
### Landing Changes
|
||||||
|
|
||||||
|
After code review is complete and “Code-Review: +1” has been received from all
|
||||||
|
reviewers, project members can commit the patch themselves:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ cd ~/crashpad/crashpad
|
||||||
|
$ git checkout work_branch
|
||||||
|
$ git cl land
|
||||||
|
```
|
||||||
|
|
||||||
|
Alternatively, patches can be committed by clicking the “Submit” button in the
|
||||||
|
Gerrit UI.
|
||||||
|
|
||||||
|
Crashpad does not currently have a [commit
|
||||||
|
queue](https://dev.chromium.org/developers/testing/commit-queue), so
|
||||||
|
contributors who are not project members will have to ask a project member to
|
||||||
|
commit the patch for them. Project members can commit changes on behalf of
|
||||||
|
external contributors by clicking the “Submit” button in the Gerrit UI.
|
||||||
|
|
||||||
|
### External Contributions
|
||||||

|
||||||
|
[Corporate Contributor License
|
||||||

## Buildbot
|
||||||
|
|
||||||
|
The [Crashpad Buildbot](https://build.chromium.org/p/client.crashpad/) performs
|
||||||
|
automated builds and tests of Crashpad. Before checking out or updating the
|
||||||
|
Crashpad source code, and after checking in a new change, it is prudent to check
|
||||||
|
the Buildbot to ensure that “the tree is green.”

== Completed
|

|
||||||
Crashpad currently consists of a crash-reporting client and some related tools
|
|
||||||
for Mac OS X and Windows. The core client work for both platforms is
|
|
||||||
substantially complete. Crashpad became the crash reporter client for
|
|
||||||
https://dev.chromium.org/Home[Chromium] on Mac OS X as of
|
|
||||||
https://chromium.googlesource.com/chromium/src/\+/d413b2dcb54d523811d386f1ff4084f677a6d089[March
|
|
||||||
2015], and on Windows as of
|
|
||||||
https://chromium.googlesource.com/chromium/src/\+/cfa5b01bb1d06bf96967bd37e21a44752801948c[November
|
|
||||||
2015].
|
|
||||||
|
|
||||||
== In Progress
|
|
||||||
|
|
||||||
Initial work on a Crashpad client for
|
|
||||||
https://crashpad.chromium.org/bug/30[Android] has begun. This is currently in
|
|
||||||
the early implementation phase.
|
|
||||||
|
|
||||||
== Future
|
|
||||||
|
|
||||||
There are plans to bring Crashpad clients to other operating systems in the
|
|
||||||
future, including a more generic non-Android Linux implementation. There are
|
|
||||||
also plans to implement a https://crashpad.chromium.org/bug/29[crash report
|
|

crashpad_handler - Crashpad’s exception handler server

== Synopsis

|
|
||||||
*crashpad_handler* ['OPTION…']
|
|
||||||
|
|
||||||
== Description
|
|
||||||
|
|
||||||
This program is Crashpad’s main exception-handling server. It is responsible for
|
|
||||||
catching exceptions, writing crash reports, and uploading them to a crash report
|
|
||||||
collection server. Uploads are disabled by default, and can only be enabled by a
|
|
||||||
Crashpad client using the Crashpad client library, typically in response to a
|
|
||||||
user requesting this behavior.
|
|
||||||
|
|
||||||
On OS X, this server may be started by its initial client, in which case it
|
|
||||||
performs a handshake with this client via a pipe established by the client that
|
|
||||||
is inherited by the server, referenced by the *--handshake-fd* argument. During
|
|
||||||
the handshake, the server furnishes the client with a send right that the client
|
|
||||||
may use as an exception port. The server retains the corresponding receive
|
|
||||||
right, which it monitors for exception messages. When the receive right loses
|
|
||||||
all senders, the server exits after allowing any upload in progress to complete.
|
|
||||||
|
|
||||||
Alternatively, on OS X, this server may be started from launchd(8), where it
|
|
||||||
receives the Mach service name in a *--mach-service* argument. It checks in with
|
|
||||||
the bootstrap server under this service name, and clients may look it up with
|
|
||||||
the bootstrap server under this service name. It monitors this service for
|
|
||||||
exception messages. Upon receipt of +SIGTERM+, the server exits after allowing
|
|
||||||
any upload in progress to complete. +SIGTERM+ is normally sent by launchd(8)
|
|
||||||
when it determines that the server should exit.
|
|
||||||
|
|
||||||
On Windows, clients register with this server by communicating with it via the
|
|
||||||
named pipe identified by the *--pipe-name* argument. Alternatively, the server
|
|
||||||
can inherit an already-created pipe from a parent process by using the
|
|
||||||
*--initial-client-data* mechanism. That argument also takes all of the arguments
|
|
||||||
that would normally be passed in a registration message, and so constitutes
|
|
||||||
registration of the first client. Subsequent clients may then register by
|
|
||||||
communicating with the server via the pipe. During registration, a client
|
|
||||||
provides the server with an OS event object that it will signal should it crash.
|
|
||||||
The server obtains the client’s process handle and waits on the crash event
|
|
||||||
object for a crash, as well as the client’s process handle for the client to
|
|
||||||
exit cleanly without crashing. When a server started via the
|
|
||||||
*--initial-client-data* mechanism loses all of its clients, it exits after
|
|
||||||
allowing any upload in progress to complete.
|
|
||||||
|
|
||||||
On Windows, this executable is built by default as a Windows GUI app, so no
|
|
||||||
console will appear in normal usage. This is the version that will typically be
|
|
||||||
used. A second copy is also made with a +.com+ extension, rather than +.exe+. In
|
|
||||||
this second copy, the PE header is modified to indicate that it's a console app.
|
|
||||||
This is useful because the +.com+ is found in the path before the +.exe+, so
|
|
||||||
when run normally from a shell using only the basename (without an explicit
|
|
||||||
+.com+ or +.exe+ extension), the +.com+ console version will be chosen, and so
|
|
||||||
stdio will be hooked up as expected to the parent console so that logging output
|
|
||||||
will be visible.
|
|
||||||
|
|
||||||
It is not normally appropriate to invoke this program directly. Usually, it will
|
|
||||||
be invoked by a Crashpad client using the Crashpad client library, or started by
|
|
||||||
another system service. On OS X, arbitrary programs may be run with a Crashpad
|
|
||||||
handler by using man_link:run_with_crashpad[1] to establish the Crashpad client
|
|
||||||
environment before running a program.
|
|
||||||
|
|
||||||
== Options
|
|
||||||
*--annotation*='KEY=VALUE'::
|
|
||||||
Sets a process-level annotation mapping 'KEY' to 'VALUE' in each crash report
|
|
||||||
that is written. This option may appear zero, one, or multiple times.
|
|
||||||
+
|
|
||||||
Most annotations should be provided by the Crashpad client as module-level
|
|
||||||
annotations instead of process-level annotations. Module-level annotations are
|
|
||||||
more flexible in that they can be modified and cleared during the client
|
|
||||||
program’s lifetime. Module-level annotations can be set via the Crashpad client
|
|
||||||
library. Process-level annotations are useful for annotations that the
|
|
||||||
collection server requires be present, that have fixed values, and for cases
|
|
||||||
where a program that does not use the Crashpad client library is being
|
|
||||||
monitored.
|
|
||||||
+
|
|
||||||
Breakpad-type collection servers only require the +"prod"+ and +"ver"+
|
|
||||||
annotations, which should be set to the product name or identifier and product
|
|
||||||
version, respectively. It is unusual to specify other annotations as
|
|
||||||
process-level annotations via this argument.
|
|
||||||
|
|
||||||
*--database*='PATH'::
|
|
||||||
Use 'PATH' as the path to the Crashpad crash report database. This option is
|
|
||||||
required. Crash reports are written to this database, and if uploads are
|
|
||||||
enabled, uploaded from this database to a crash report collection server. If the
|
|
||||||
database does not exist, it will be created, provided that the parent directory
|
|
||||||
of 'PATH' exists.
|
|
||||||
|
|
||||||
*--handshake-fd*='FD'::
|
|
||||||
Perform the handshake with the initial client on the file descriptor at 'FD'.
|
|
||||||
Either this option or *--mach-service*, but not both, is required. This option
|
|
||||||
is only valid on OS X.
|
|
||||||
|
|
||||||
*--initial-client-data*='HANDLE_request_crash_dump','HANDLE_request_non_crash_dump','HANDLE_non_crash_dump_completed','HANDLE_first_pipe_instance','HANDLE_client_process','Address_crash_exception_information','Address_non_crash_exception_information','Address_debug_critical_section'::
|
|
||||||
Register the initial client using the inherited handles and data provided. For
|
|
||||||
more information on the arguments, see the implementations of +CrashpadClient+
|
|
||||||
and +ExceptionHandlerServer+. Either this option or *--pipe-name*, but not both,
|
|
||||||
is required. This option is only valid on Windows.
|
|
||||||
+
|
|
||||||
When this option is present, the server creates a new named pipe at a random
|
|
||||||
name and informs its client of the name. The server waits for at least one
|
|
||||||
client to register, and exits when all clients have exited, after waiting for
|
|
||||||
any uploads in progress to complete.
|
|
||||||
|
|
||||||
*--mach-service*='SERVICE'::
|
|
||||||
Check in with the bootstrap server under the name 'SERVICE'. Either this option
|
|
||||||
or *--handshake-fd*, but not both, is required. This option is only valid on OS
|
|
||||||
X.
|
|
||||||
+
|
|
||||||
'SERVICE' may already be reserved with the bootstrap server in cases where this
|
|
||||||
tool is started by launchd(8) as a result of a message being sent to a service
|
|
||||||
declared in a job’s +MachServices+ dictionary (see launchd.plist(5)). The
|
|
||||||
service name may also be completely unknown to the system.
|
|
||||||
|
|
||||||
*--no-rate-limit*::
|
|
||||||
Do not rate limit the upload of crash reports. By default uploads are throttled
|
|
||||||
to one per hour. Using this option disables that behavior, and Crashpad will
|
|
||||||
attempt to upload all captured reports.
|
|
||||||
|
|
||||||
*--pipe-name*='PIPE'::
|
|
||||||
Listen on the given pipe name for connections from clients. 'PIPE' must be of
|
|
||||||
the form +\\.\pipe\<somename>+. Either this option or *--initial-client-data*,
|
|
||||||
but not both, is required. This option is only valid on Windows.
|
|
||||||
+
|
|
||||||
When this option is present, the server creates a named pipe at 'PIPE', a name
|
|
||||||
known to both the server and its clients. The server continues running even
|
|
||||||
after all clients have exited.
|
|
||||||
|
|
||||||
*--reset-own-crash-exception-port-to-system-default*::
|
|
||||||
Causes the exception handler server to set its own crash handler to the system
|
|
||||||
default before beginning operation. This is only expected to be useful in cases
|
|
||||||
where the server inherits an inappropriate crash handler from its parent
|
|
||||||
process. This option is only valid on OS X. Use of this option is discouraged.
|
|
||||||
It should not be used absent extraordinary circumstances.
|
|
||||||
|
|
||||||
*--url*='URL'::
|
|
||||||
If uploads are enabled, sends crash reports to the Breakpad-type crash report
|
|
||||||
collection server at 'URL'. Uploads are disabled by default, and can only be
|
|
||||||
enabled for a database by a Crashpad client using the Crashpad client library,
|
|
||||||
typically in response to a user requesting this behavior. If this option is not
|
|
||||||
specified, this program will behave as if uploads are disabled.
|
|
||||||
|
|
||||||
*--help*::
|
|
||||||
Display help and exit.
|
|
||||||
|
|
||||||
*--version*::
|
|
||||||
Output version information and exit.
|
|
||||||
|
|
||||||
== Exit Status
|
|
||||||
|
|
||||||
*0*::
|
|
||||||
Success.
|
|
||||||
|
|
||||||
*1*::
|
|
||||||
Failure, with a message printed to the standard error stream.

handler by using [run_with_crashpad(1)](../tools/mac/run_with_crashpad.md) to
|
||||||
|
establish the Crashpad client environment before running a program.
|
||||||
|
|
||||||
|
## Options
|
||||||
|
|
||||||
|
* **--annotation**=_KEY_=_VALUE_
|
||||||
|
|
||||||
|
Sets a process-level annotation mapping _KEY_ to _VALUE_ in each crash report
|
||||||
|
that is written. This option may appear zero, one, or multiple times.
|
||||||
|
|
||||||
|
Most annotations should be provided by the Crashpad client as module-level
|
||||||
|
annotations instead of process-level annotations. Module-level annotations
|
||||||
|
are more flexible in that they can be modified and cleared during the client
|
||||||
|
program’s lifetime. Module-level annotations can be set via the Crashpad
|
||||||
|
client library. Process-level annotations are useful for annotations that the
|
||||||
|
collection server requires be present, that have fixed values, and for cases
|
||||||
|
where a program that does not use the Crashpad client library is being
|
||||||
|
monitored.
|
||||||
|
|
||||||
|
Breakpad-type collection servers only require the `"prod"` and `"ver"`
|
||||||
|
annotations, which should be set to the product name or identifier and
|
||||||
|
product version, respectively. It is unusual to specify other annotations as
|
||||||
|
process-level annotations via this argument.
|
||||||
|
|
||||||
|
* **--database**=_PATH_
|
||||||
|
|
||||||
|
Use _PATH_ as the path to the Crashpad crash report database. This option is
|
||||||
|
required. Crash reports are written to this database, and if uploads are
|
||||||
|
enabled, uploaded from this database to a crash report collection server. If
|
||||||
|
the database does not exist, it will be created, provided that the parent
|
||||||
|
directory of _PATH_ exists.
|
||||||
|
|
||||||
|
* **--handshake-fd**=_FD_
|
||||||
|
|
||||||
|
Perform the handshake with the initial client on the file descriptor at _FD_.
|
||||||
|
Either this option or **--mach-service**, but not both, is required. This
|
||||||
|
option is only valid on macOS.
|
||||||
|
|
||||||
|
* **--initial-client-data**=*HANDLE_request_crash_dump*,
|
||||||
|
*HANDLE_request_non_crash_dump_*,*HANDLE_non_crash_dump_completed*,*HANDLE_first_pipe_instance*,*HANDLE_client_process*,*Address_crash_exception_information*,*Address_non_crash_exception_information*,*Address_debug_critical_section*
|
||||||
|
|
||||||
|
Register the initial client using the inherited handles and data provided.
|
||||||
|
For more information on the arguments, see the implementations of
|
||||||
|
`CrashpadClient` and `ExceptionHandlerServer`. Either this option or
|
||||||
|
**--pipe-name**, but not both, is required. This option is only valid on
|
||||||
|
Windows.
|
||||||
|
|
||||||
|
When this option is present, the server creates a new named pipe at a random
|
||||||
|
name and informs its client of the name. The server waits for at least one
|
||||||
|
client to register, and exits when all clients have exited, after waiting for
|
||||||
|
any uploads in progress to complete.
|
||||||
|
|
||||||
|
* **--mach-service**=_SERVICE_
|
||||||
|
|
||||||
|
Check in with the bootstrap server under the name _SERVICE_. Either this
|
||||||
|
option or **--handshake-fd**, but not both, is required. This option is only
|
||||||
|
valid on macOS.
|
||||||
|
|
||||||
|
_SERVICE_ may already be reserved with the bootstrap server in cases where
|
||||||
|
this tool is started by launchd(8) as a result of a message being sent to a
|
||||||
|
service declared in a job’s `MachServices` dictionary (see launchd.plist(5)).
|
||||||
|
The service name may also be completely unknown to the system.
|
||||||
|
|
||||||
|
* **--no-rate-limit**
|
||||||
|
|
||||||
|
Do not rate limit the upload of crash reports. By default uploads are
|
||||||
|
throttled to one per hour. Using this option disables that behavior, and
|
||||||
|
Crashpad will attempt to upload all captured reports.
|
||||||
|
|
||||||
|
* **--pipe-name**=_PIPE_
|
||||||
|
|
||||||
|
Listen on the given pipe name for connections from clients. _PIPE_ must be of
|
||||||
|
the form `\\.\pipe\<somename>`. Either this option or
|
||||||
|
**--initial-client-data**, but not both, is required. This option is only
|
||||||
|
valid on Windows.
|
||||||
|
|
||||||
|
When this option is present, the server creates a named pipe at _PIPE_, a
|
||||||
|
name known to both the server and its clients. The server continues running
|
||||||
|
even after all clients have exited.
|
||||||
|
|
||||||
|
* **--reset-own-crash-exception-port-to-system-default**
|
||||||
|
|
||||||
|
Causes the exception handler server to set its own crash handler to the
|
||||||
|
system default before beginning operation. This is only expected to be useful
|
||||||
|
in cases where the server inherits an inappropriate crash handler from its
|
||||||
|
parent process. This option is only valid on macOS. Use of this option is
|
||||||
|
discouraged. It should not be used absent extraordinary circumstances.
|
||||||
|
|
||||||
|
* **--url**=_URL_
|
||||||
|
|
||||||
|
If uploads are enabled, sends crash reports to the Breakpad-type crash report
|
||||||
|
collection server at _URL_. Uploads are disabled by default, and can only be
|
||||||
|
enabled for a database by a Crashpad client using the Crashpad client
|
||||||
|
library, typically in response to a user requesting this behavior. If this
|
||||||
|
option is not specified, this program will behave as if uploads are disabled.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.
|
||||||
|
|
||||||
|
* **--version**
|
||||||
|
|
||||||
|
Output version information and exit.
|
||||||
|
|
||||||
|
## Exit Status
|
||||||
|
|
||||||
|
* **0**
|
||||||
|
|
||||||
|
Success.
|
||||||
|
|
||||||
|
* **1**
|
||||||
|
|
||||||
|
Failure, with a message printed to the standard error stream.

== Name

|
|

crashpad_database_util - Operate on Crashpad crash report databases
|
|
||||||
|
|

== Synopsis
|

|
|
||||||
[verse]
|
|
||||||
*crashpad_database_util* ['OPTION…']
|
|
||||||
|
|
||||||
== Description
|
|
||||||
|
|
||||||
Operates on Crashpad crash report databases. The database’s settings can be
|
|
||||||
queried and modified, and information about crash reports stored in the
|
|
||||||
database can be displayed.
|
|
||||||
|
|
||||||
When this program is requested to both show and set information in a single
|
|
||||||
invocation, all “show” operations will be completed prior to beginning any “set”
|
|
||||||
operation.
|
|
||||||
|
|
||||||
Programs that use the Crashpad client library directly will not normally use
|
|
||||||
this tool, but may use the database through the programmatic interfaces in the
|
|
||||||
client library. This tool exists to allow developers to manipulate a Crashpad
|
|
||||||
database.
|
|
||||||
|
|
||||||
== Options
|
|
||||||
*--create*::
|
|
||||||
Creates the database identified by *--database* if it does not exist, provided
|
|
||||||
that the parent directory of 'PATH' exists.
|
|
||||||
|
|
||||||
*-d*, *--database*='PATH'::
|
|
||||||
Use 'PATH' as the path to the Crashpad crash report database. This option is
|
|
||||||
required. The database must already exist unless *--create* is also specified.
|
|
||||||
|
|
||||||
*--show-client-id*::
|
|
||||||
Show the client ID stored in the database’s settings. The client ID is formatted
|
|
||||||
as a UUID. The client ID is set when the database is created.
|
|
||||||
man_link:crashpad_handler[8] retrieves the client ID and stores it in crash
|
|
||||||
reports as they are written.
|
|
||||||
|
|
||||||
*--show-uploads-enabled*::
|
|
||||||
Show the status of the uploads-enabled bit stored in the database’s settings.
|
|
||||||
man_link:crashpad_handler[8] does not upload reports when this bit is false.
|
|
||||||
This bit is false when a database is created, and is under an application’s
|
|
||||||
control via the Crashpad client library interface.
|
|
||||||
+
|
|
||||||
See also *--set-uploads-enabled*.
|
|
||||||
|
|
||||||
*--show-last-upload-attempt-time*::
|
|
||||||
Show the last-upload-attempt time stored in the database’s settings. This value
|
|
||||||
is +0+, meaning “never,” when the database is created.
|
|
||||||
man_link:crashpad_handler[8] consults this value before attempting an upload to
|
|
||||||
implement its rate-limiting behavior. The database updates this value whenever
|
|
||||||
an upload is attempted.
|
|
||||||
+
|
|
||||||
See also *--set-last-upload-attempt-time*.
|
|
||||||
|
|
||||||
*--show-pending-reports*::
|
|
||||||
Show reports eligible for upload.
|
|
||||||
|
|
||||||
*--show-completed-reports*::
|
|
||||||
Show reports not eligible for upload. A report is moved from the “pending” state
|
|
||||||
to the “completed” state by man_link:crashpad_handler[8]. This may happen when a
|
|
||||||
report is successfully uploaded, when a report is not uploaded because uploads
|
|
||||||
are disabled, or when a report upload attempt fails and will not be retried.
|
|
||||||
|
|
||||||
*--show-all-report-info*::
|
|
||||||
With *--show-pending-reports* or *--show-completed-reports*, show all metadata
|
|
||||||
for each report displayed. Without this option, only report IDs will be shown.
|
|
||||||
|
|
||||||
*--show-report*='UUID'::
|
|
||||||
Show a report from the database looked up by its identifier, 'UUID', which must
|
|
||||||
be formatted in string representation per RFC 4122 §3. All metadata for each
|
|
||||||
report found via a *--show-report* option will be shown. If 'UUID' is not found,
|
|
||||||
the string +"not found"+ will be printed. If this program is only requested to
|
|
||||||
show a single report and it is not found, it will treat this as a failure for
|
|
||||||
the purposes of determining its exit status. This option may appear multiple
|
|
||||||
times.
|
|
||||||
|
|
||||||
*--set-report-uploads-enabled*='BOOL'::
|
|
||||||
Enable or disable report upload in the database’s settings. 'BOOL' is a string
|
|
||||||
representation of a boolean value, such as +"0"+ or +"true"+.
|
|
||||||
+
|
|
||||||
See also *--show-uploads-enabled*.
|
|
||||||
|
|
||||||
*--set-last-upload-attempt-time*='TIME'::
|
|
||||||
Set the last-upload-attempt time in the database’s settings. 'TIME' is a string
|
|
||||||
representation of a time, which may be in 'yyyy-mm-dd hh:mm:ss' format, a
|
|
||||||
numeric +time_t+ value, or the special string +"never"+.
|
|
||||||
+
|
|
||||||
See also *--show-last-upload-attempt-time*.
|
|
||||||
|
|
||||||
*--new-report*='PATH'::
|
|
||||||
Submit a new report located at 'PATH' to the database. If 'PATH' is +"-"+, the
|
|
||||||
new report will be read from standard input. The new report will be in the
|
|
||||||
“pending” state. The UUID assigned to the new report will be printed. This
|
|
||||||
option may appear multiple times.
|
|
||||||
|
|
||||||
*--utc*::
|
|
||||||
When showing times, do so in UTC as opposed to the local time zone. When setting
|
|
||||||
times, interpret ambiguous time strings in UTC as opposed to the local time
|
|
||||||
zone.
|
|
||||||
|
|
||||||
*--help*::
|
|
||||||
Display help and exit.
|
|
||||||
|
|
||||||
*--version*::
|
|
||||||
Output version information and exit.
|
|
||||||
|
|
||||||
== Examples
|
|
||||||
|
|
||||||
Shows all crash reports in a crash report database that are in the “completed”
|
|
||||||
state.

|
## Name
|
||||||
|
|
||||||
|
crashpad_database_util—Operate on Crashpad crash report databases
|
||||||
|
|
||||||
|
## Synopsis
|
||||||
|
|
||||||
|
**crashpad_database_util** [_OPTION…_]
|
||||||
|
|
||||||
|
## Description
|
||||||
|
|
||||||
|
Operates on Crashpad crash report databases. The database’s settings can be
|
||||||
|
queried and modified, and information about crash reports stored in the database
|
||||||
|
can be displayed.
|
||||||
|
|
||||||
|
When this program is requested to both show and set information in a single
|
||||||
|
invocation, all “show” operations will be completed prior to beginning any “set”
|
||||||
|
operation.
|
||||||
|
|
||||||
|
Programs that use the Crashpad client library directly will not normally use
|
||||||
|
this tool, but may use the database through the programmatic interfaces in the
|
||||||
|
client library. This tool exists to allow developers to manipulate a Crashpad
|
||||||
|
database.
|
||||||
|
|
||||||
|
## Options
|
||||||
|
|
||||||
|
* **--create**
|
||||||
|
|
||||||
|
Creates the database identified by **--database** if it does not exist,
|
||||||
|
provided that the parent directory of _PATH_ exists.
|
||||||
|
|
||||||
|
* **-d**, **--database**=_PATH_
|
||||||
|
|
||||||
|
Use _PATH_ as the path to the Crashpad crash report database. This option is
|
||||||
|
required. The database must already exist unless **--create** is also
|
||||||
|
specified.
|
||||||
|
|
||||||
|
* **--show-client-id**
|
||||||
|
|
||||||
|
Show the client ID stored in the database’s settings. The client ID is
|
||||||
|
formatted as a UUID. The client ID is set when the database is created.
|
||||||
|
[crashpad_handler(8)](../handler/crashpad_handler.md) retrieves the client ID
|
||||||
|
and stores it in crash reports as they are written.
|
||||||
|
|
||||||
|
* **--show-uploads-enabled**
|
||||||
|
|
||||||
|
Show the status of the uploads-enabled bit stored in the database’s settings.
|
||||||
|
[crashpad_handler(8)](../handler/crashpad_handler.md) does not upload reports
|
||||||
|
when this bit is false. This bit is false when a database is created, and is
|
||||||
|
under an application’s control via the Crashpad client library interface.
|
||||||
|
|
||||||
|
See also **--set-uploads-enabled**.
|
||||||
|
|
||||||
|
* **--show-last-upload-attempt-time**
|
||||||
|
|
||||||
|
Show the last-upload-attempt time stored in the database’s settings. This
|
||||||
|
value is `0`, meaning “never,” when the database is created.
|
||||||
|
[crashpad_handler(8)](../handler/crashpad_handler.md) consults this value
|
||||||
|
before attempting an upload to implement its rate-limiting behavior. The
|
||||||
|
database updates this value whenever an upload is attempted.
|
||||||
|
|
||||||
|
See also **--set-last-upload-attempt-time**.
|
||||||
|
|
||||||
|
* **--show-pending-reports**
|
||||||
|
|
||||||
|
Show reports eligible for upload.
|
||||||
|
|
||||||
|
* **--show-completed-reports**
|
||||||
|
|
||||||
|
Show reports not eligible for upload. A report is moved from the “pending”
|
||||||
|
state to the “completed” state by
|
||||||
|
[crashpad_handler(8)](../handler/crashpad_handler.md). This may happen when a
|
||||||
|
report is successfully uploaded, when a report is not uploaded because
|
||||||
|
uploads are disabled, or when a report upload attempt fails and will not be
|
||||||
|
retried.
|
||||||
|
|
||||||
|
* **--show-all-report-info**
|
||||||
|
|
||||||
|
With **--show-pending-reports** or **--show-completed-reports**, show all
|
||||||
|
metadata for each report displayed. Without this option, only report IDs will
|
||||||
|
be shown.
|
||||||
|
|
||||||
|
* **--show-report**=_UUID_
|
||||||
|
|
||||||
|
Show a report from the database looked up by its identifier, _UUID_, which
|
||||||
|
must be formatted in string representation per RFC 4122 §3. All metadata for
|
||||||
|
each report found via a **--show-report** option will be shown. If _UUID_ is
|
||||||
|
not found, the string `"not found"` will be printed. If this program is only
|
||||||
|
requested to show a single report and it is not found, it will treat this as
|
||||||
|
a failure for the purposes of determining its exit status. This option may
|
||||||
|
appear multiple times.
|
||||||
|
|
||||||
|
* **--set-report-uploads-enabled**=_BOOL_
|
||||||
|
|
||||||
|
Enable or disable report upload in the database’s settings. _BOOL_ is a
|
||||||
|
string representation of a boolean value, such as `"0"` or `"true"`.
|
||||||
|
|
||||||
|
See also **--show-uploads-enabled**.
|
||||||
|
|
||||||
|
* **--set-last-upload-attempt-time**=_TIME_
|
||||||
|
|
||||||
|
Set the last-upload-attempt time in the database’s settings. _TIME_ is a
|
||||||
|
string representation of a time, which may be in _yyyy-mm-dd hh:mm:ss_
|
||||||
|
format, a numeric `time_t` value, or the special string `"never"`.
|
||||||
|
|
||||||
|
See also **--show-last-upload-attempt-time**.
|
||||||
|
|
||||||
|
* **--new-report**=_PATH_
|
||||||
|
|
||||||
|
Submit a new report located at _PATH_ to the database. If _PATH_ is `"-"`,
|
||||||
|
the new report will be read from standard input. The new report will be in
|
||||||
|
the “pending” state. The UUID assigned to the new report will be printed.
|
||||||
|
This option may appear multiple times.
|
||||||
|
|
||||||
|
* **--utc**
|
||||||
|
|
||||||
|
When showing times, do so in UTC as opposed to the local time zone. When
|
||||||
|
setting times, interpret ambiguous time strings in UTC as opposed to the
|
||||||
|
local time zone.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.
|
||||||
|
|
||||||
|
* **--version**
|
||||||
|
|
||||||
|
Output version information and exit.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
Shows all crash reports in a crash report database that are in the “completed”
|
||||||
|
state.
|
||||||

|
||||||
|
```
|
||||||
|
|
||||||
|
Disables report upload in a crash report database’s settings, and then verifies
|
||||||
|
that the change was made.
|
||||||

|
||||||
|
|
||||||
|
* **0**
|
||||||
|
|
||||||
|

== Name

generate_dump - Generate a minidump file containing a snapshot of a running
|
|
||||||
process

== Synopsis
|
|
||||||
|
|
||||||
[verse]
|
|
||||||
*generate_dump* ['OPTION…'] 'PID'
|
|
||||||
|
|
||||||
== Description
|
|
||||||
|
|
||||||
Generates a minidump file containing a snapshot of a running process whose
|
|
||||||
process identifier is 'PID'. By default, the target process will be suspended
|
|
||||||
while the minidump is generated, and the minidump file will be written to
|
|
||||||
+minidump.PID+. After the minidump file is generated, the target process resumes
|
|
||||||
running.
|
|
||||||
|
|
||||||
The minidump file will contain information about the process, its threads, its
|
|
||||||
modules, and the system. It will not contain any exception information because
|
|
||||||
it will be generated from a live running process, not as a result of an
|
|
||||||
exception occurring.
|
|
||||||
|
|
||||||
This program uses +task_for_pid()+ to access the process’ task port. This
|
|
||||||
operation may be restricted to use by the superuser, executables signed by an
|
|
||||||
authority trusted by the system, and processes otherwise permitted by
|
|
||||||
taskgated(8). Consequently, this program must normally either be signed or be
|
|
||||||
invoked by root. It is possible to install this program as a setuid root
|
|
||||||
executable to overcome this limitation.
|
|
||||||
|
|
||||||
This program is similar to the gcore(1) program available on some operating
|
|
||||||
systems.
|
|
||||||
|
|
||||||
== Options
|
|
||||||
|
|
||||||
*-r*, *--no-suspend*::
|
|
||||||
The target process will continue running while the minidump file is generated.
|
|
||||||
Normally, the target process is suspended during this operation, which
|
|
||||||
guarantees that the minidump file will contain an atomic snapshot of the
|
|
||||||
process.
|
|
||||||
+
|
|
||||||
This option may be useful when attempting to generate a minidump from a process
|
|
||||||
that dump generation has an interprocess dependency on, such as a system server
|
|
||||||
like launchd(8) or opendirectoryd(8). Deadlock could occur if any portion of the
|
|
||||||
dump generation operation blocks while waiting for a response from one of these
|
|
||||||
servers while they are suspended.
|
|
||||||
|
|
||||||
*-o*, *--output*='FILE'::
|
|
||||||
The minidump will be written to 'FILE' instead of +minidump.PID+.
|
|
||||||
|
|
||||||
*--help*::
|
|
||||||
Display help and exit.
|
|
||||||
|
|
||||||
*--version*::
|
|
||||||
Output version information and exit.
|
|
||||||
|
|
||||||
== Examples
|
|
||||||
|
|
||||||
Generate a minidump file in +/tmp/minidump+ containing a snapshot of the process
|
|
||||||
with PID 1234.

# generate_dump(1)
|

|
|

|
## Name
|
||||||
|
|
||||||
|
generate_dump—Generate a minidump file containing a snapshot of a running
|
||||||
|
process
|
||||||
|
|
||||||
|
## Synopsis
|
||||||
|
|
||||||
|
**generate_dump** [_OPTION…_] _PID_
|
||||||
|
|
||||||
|
## Description
|
||||||
|
|
||||||
|
Generates a minidump file containing a snapshot of a running process whose
|
||||||
|
process identifier is _PID_. By default, the target process will be suspended
|
||||||
|
while the minidump is generated, and the minidump file will be written to
|
||||||
|
`minidump.PID`. After the minidump file is generated, the target process resumes
|
||||||
|
running.
|
||||||
|
|
||||||
|
The minidump file will contain information about the process, its threads, its
|
||||||
|
modules, and the system. It will not contain any exception information because
|
||||||
|
it will be generated from a live running process, not as a result of an
|
||||||
|
exception occurring.
|
||||||
|
|
||||||
|
On macOS, this program uses `task_for_pid()` to access the process’ task port.
|
||||||
|
This operation may be restricted to use by the superuser, executables signed by
|
||||||
|
an authority trusted by the system, and processes otherwise permitted by
|
||||||
|
taskgated(8). Consequently, this program must normally either be signed or be
|
||||||
|
invoked by root. It is possible to install this program as a setuid root
|
||||||
|
executable to overcome this limitation, although it will remain impossible to
|
||||||
|
generate dumps for processes protected by [System Integrity Protection
|
||||||
|
(SIP)](https://support.apple.com/HT204899), including those whose “restrict”
|
||||||
|
codesign(1) option is respected.
|
||||||
|
|
||||||
|
This program is similar to the gcore(1) program available on some operating
|
||||||
|
systems.
|
||||||
|
|
||||||
|
## Options
|
||||||
|
|
||||||
|
* **-r**, **--no-suspend**
|
||||||
|
|
||||||
|
The target process will continue running while the minidump file is
|
||||||
|
generated. Normally, the target process is suspended during this operation,
|
||||||
|
which guarantees that the minidump file will contain an atomic snapshot of
|
||||||

the process.

|
||||||
|
|
||||||
|
* **-o**, **--output**=_FILE_
|
||||||
|
|
||||||
|
The minidump will be written to _FILE_ instead of `minidump.PID`.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.

|
|
||||||
|
Output version information and exit.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
Generate a minidump file in `/tmp/minidump` containing a snapshot of the process
|
||||||
|
with PID 1234.
|

*catch_exception_tool* *-m* 'SERVICE' ['OPTION…']
|
|
||||||
|
|
||||||
== Description
|
|
||||||
|
|
||||||
Runs a Mach exception server registered with the bootstrap server under the name
|
|
||||||
'SERVICE'. The exception server is capable of receiving exceptions for
|
|
||||||
“behavior” values of +EXCEPTION_DEFAULT+, +EXCEPTION_STATE+, and
|
|
||||||
+EXCEPTION_STATE_IDENTITY+, with or without +MACH_EXCEPTION_CODES+ set.
|
|
||||||
|
|
||||||
== Options
|
|
||||||
|
|
||||||
*-f*, *--file*='FILE'::
|
|
||||||
Information about the exception will be appended to 'FILE' instead of the
|
|
||||||
standard output stream.
|
|
||||||
|
|
||||||
*-m*, *--mach-service*='SERVICE'::
|
|
||||||
Check in with the bootstrap server under the name 'SERVICE'. This service name
|
|
||||||
may already be reserved with the bootstrap server in cases where this tool is
|
|
||||||
started by launchd(8) as a result of a message being sent to a service declared
|
|
||||||
in a job’s +MachServices+ dictionary (see launchd.plist(5)). The service name
|
|
||||||
may also be completely unknown to the system.
|
|
||||||
|
|
||||||
*-p*, *--persistent*::
|
|
||||||
Continue processing exceptions after the first one. The default mode is
|
|
||||||
one-shot, where this tool exits after processing the first exception.
|
|
||||||
|
|
||||||
*-t*, *--timeout*='TIMEOUT'::
|
|
||||||
Run for a maximum of 'TIMEOUT' seconds. Specify +0+ to request non-blocking
|
|
||||||
operation, in which the tool exits immediately if no exception is received. In
|
|
||||||
*--persistent* mode, 'TIMEOUT' applies to the overall duration that this tool
|
|
||||||
will run, not to the processing of individual exceptions. When *--timeout* is
|
|
||||||
not specified, this tool will block indefinitely while waiting for an exception.
|
|
||||||
|
|
||||||
*--help*::
|
|
||||||
Display help and exit.
|
|
||||||
|
|
||||||
*--version*::
|
|
||||||
Output version information and exit.
|

# catch_exception_tool(1)
|
||||||
|
|
||||||
|
## Name
|
||||||
|
|
||||||
|
catch_exception_tool—Catch Mach exceptions and display information about them
|
||||||
|
|
||||||
|
## Synopsis
|
||||||
|
|
||||||
|
**catch_exception_tool** **-m** _SERVICE_ [_OPTION…_]
|
||||||
|
|
||||||
|
## Description
|
||||||
|
|
||||||
|
Runs a Mach exception server registered with the bootstrap server under the name
|
||||||
|
_SERVICE_. The exception server is capable of receiving exceptions for
|
||||||
|
“behavior” values of `EXCEPTION_DEFAULT`, `EXCEPTION_STATE`, and
|
||||||
|
`EXCEPTION_STATE_IDENTITY`, with or without `MACH_EXCEPTION_CODES` set.
|
||||||
|
|
||||||
|
## Options
|
||||||
|
|
||||||
|
* **-f**, **--file**=_FILE_
|
||||||
|
|
||||||
|
Information about the exception will be appended to _FILE_ instead of the
|
||||||
|
standard output stream.
|
||||||
|
|
||||||
|
* **-m**, **--mach-service**=_SERVICE_
|
||||||
|
|
||||||
|
Check in with the bootstrap server under the name _SERVICE_. This service
|
||||||
|
name may already be reserved with the bootstrap server in cases where this
|
||||||
|
tool is started by launchd(8) as a result of a message being sent to a
|
||||||
|
service declared in a job’s `MachServices` dictionary (see launchd.plist(5)).
|
||||||
|
The service name may also be completely unknown to the system.
|
||||||
|
|
||||||
|
* **-p**, **--persistent**
|
||||||
|
|
||||||
|
Continue processing exceptions after the first one. The default mode is
|
||||||
|
one-shot, where this tool exits after processing the first exception.
|
||||||
|
|
||||||
|
* **-t**, **--timeout**=_TIMEOUT_
|
||||||
|
|
||||||
|
Run for a maximum of _TIMEOUT_ seconds. Specify `0` to request non-blocking
|
||||||
|
operation, in which the tool exits immediately if no exception is received.
|
||||||
|
In **--persistent** mode, _TIMEOUT_ applies to the overall duration that this
|
||||||
|
tool will run, not to the processing of individual exceptions. When
|
||||||
|
**--timeout** is not specified, this tool will block indefinitely while
|
||||||
|
waiting for an exception.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.
|
||||||
|
|
||||||
|
* **--version**
|
||||||
|
|
||||||
|
Output version information and exit.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
Run a one-shot blocking exception server registered with the bootstrap server
|
||||||
|
under the name `svc`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ catch_exception_tool --mach-service=svc --file=out &
|
||||||
|
[1] 1233
|
||||||
|
$ exception_port_tool --set-handler=handler=bootstrap:svc crasher
|
||||||
|
Illegal instruction: 4
|
||||||
|
[1]+ Done catch_exception_tool --mach-service=svc --file=out
|
||||||
|
$ cat out
|
||||||
|
catch_exception_tool: behavior EXCEPTION_DEFAULT|MACH_EXCEPTION_CODES, pid 1234, thread 56789, exception EXC_CRASH, codes[2] 0x4200001, 0, original exception EXC_BAD_INSTRUCTION, original code[0] 1, signal SIGILL
|
||||||
|
```
|
||||||
|
|
||||||
|
Run an on-demand exception server started by launchd(5) available via the
|
||||||
|
bootstrap server under the name `svc`:
|
||||||
|
|
||||||
|
```
|
||||||
|
$ `on_demand_service_tool --load --label=catch_exception \
|
||||||
|
--mach-service=svc \
|
||||||
|
$(which catch_exception_tool) --mach-service=svc \
|
||||||
|
--file=/tmp/out --persistent --timeout=0
|
||||||
|
$ exception_port_tool --set-handler=handler=bootstrap:svc crasher
|
||||||
|
Illegal instruction: 4
|
||||||
|
$ on_demand_service_tool --unload --label=catch_exception
|
||||||
|
$ cat /tmp/out
|
||||||
|
catch_exception_tool: behavior EXCEPTION_DEFAULT|MACH_EXCEPTION_CODES, pid 2468, thread 13579, exception EXC_CRASH, codes[2] 0x4200001, 0, original exception EXC_BAD_INSTRUCTION, original code[0] 1, signal SIGILL
|
||||||
|
```
|
||||||
|
|
||||||
|
## Exit Status
|
||||||
|
|
||||||
|
* **0**
|
||||||
|
|
||||||
|
Success. In **--persistent** mode with a **--timeout** set, it is considered
|
||||||
|
successful if at least one exception was caught when the timer expires.
|
||||||
|
|
||||||
|
* **1**
|
||||||
|
|
||||||
|
Failure, with a message printed to the standard error stream.

|
||||||
== Name
|
|
||||||
|
|
||||||
exception_port_tool - Show and change Mach exception ports
|
|
||||||
|
|
||||||
== Synopsis
|
|
||||||
|
|
||||||
[verse]
|
|
||||||
*exception_port_tool* ['OPTION…'] ['COMMAND' ['ARG…']]
|
|
||||||
|
|
||||||
== Description
|
|
||||||
|
|
||||||
Shows Mach exception ports registered for a thread, task, or host target with a
|
|
||||||
*--show-** option, changes Mach exception ports with *--set-handler*, shows
|
|
||||||
changes with a *--show-new-** option, and executes 'COMMAND' along with any
|
|
||||||
arguments specified ('ARG…') with the changed exception ports in effect.
|
|
||||||
|
|
||||||
== Options
|
|
||||||
*-s*, *--set-handler*='DESCRIPTION'::
|
|
||||||
Set an exception port to 'DESCRIPTION'. This option may appear zero, one, or
|
|
||||||
more times.
|
|
||||||
+
|
|
||||||
'DESCRIPTION' is formatted as a comma-separated sequence of tokens, where each
|
|
||||||
token consists of a key and value separated by an equals sign. These keys are
|
|
||||||
recognized:
|
|
||||||
+
|
|
||||||
*target*='TARGET':::
|
|
||||||
'TARGET' defines which target’s exception ports to set: *host*, *task*, or
|
|
||||||
*thread*. The default value of 'TARGET' is *task*. Operations on *host* are
|
|
||||||
restricted to the superuser.
|
|
||||||
+
|
|
||||||
*mask*='MASK':::
|
|
||||||
'MASK' defines the mask of exception types to handle, from
|
|
||||||
+<mach/exception_types.h>+. This can be *BAD_ACCESS*, *BAD_INSTRUCTION*,
|
|
||||||
*ARITHMETIC*, *EMULATION*, *SOFTWARE*, *BREAKPOINT*, *SYSCALL*, *MACH_SYSCALL*,
|
|
||||||
*RPC_ALERT*, *CRASH*, *RESOURCE*, *GUARD*, or *CORPSE_NOTIFY*. Different
|
|
||||||
exception types may be combined by combining them with pipe characters (*|*).
|
|
||||||
The special value *ALL* includes each exception type except for *CRASH*. To
|
|
||||||
truly specify all exception types including *CRASH*, use *ALL|CRASH*. The
|
|
||||||
default value of 'MASK' is *CRASH*.
|
|
||||||
+
|
|
||||||
*behavior*='BEHAVIOR':::
|
|
||||||
'BEHAVIOR' defines the specific exception handler routine to be called when an
|
|
||||||
exception occurs. This can be *DEFAULT*, *STATE*, or *STATE_IDENTITY*. *MACH*
|
|
||||||
may also be specified by combining them with pipe characters (*|*). The most
|
|
||||||
complete set of exception information is provided with *STATE_IDENTITY|MACH*.
|
|
||||||
Not all exception servers implement all possible behaviors. The default value of
|
|
||||||
'BEHAVIOR' is *DEFAULT|MACH*.
|
|
||||||
+
|
|
||||||
*flavor*='FLAVOR':::
|
|
||||||
For state-carrying values of 'BEHAVIOR' (those including *STATE* or
|
|
||||||
*STATE_IDENTITY*), 'FLAVOR' specifies the architecture-specific thread state
|
|
||||||
flavor to be provided to the exception handler. For the x86 family, this can be
|
|
||||||
*THREAD*, *THREAD32*, *THREAD64*, *FLOAT*, *FLOAT32*, *FLOAT64*, *DEBUG*,
|
|
||||||
*DEBUG32*, or *DEBUG64*. The default value of 'FLAVOR' is *NONE*, which is not
|
|
||||||
valid for state-carrying values of 'BEHAVIOR'.
|
|
||||||
+
|
|
||||||
*handler*='HANDLER':::
|
|
||||||
'HANDLER' defines the exception handler. *NULL* indicates that any existing
|
|
||||||
exception port should be cleared. 'HANDLER' may also take the form
|
|
||||||
*bootstrap*:__SERVICE__, which will look 'SERVICE' up with the bootstrap server
|
|
||||||
and set that service as the exception handler. The default value of 'HANDLER' is
|
|
||||||
*NULL*.
|
|
||||||
|
|
||||||
*--show-bootstrap*='SERVICE'::
|
|
||||||
Looks up 'SERVICE' with the bootstrap server and shows it. Normally, the handler
|
|
||||||
port values displayed by the other *--show-** options are meaningless
|
|
||||||
handles, but by comparing them to the port values for known bootstrap services,
|
|
||||||
it is possible to verify that they are set as intended.
|
|
||||||
|
|
||||||
*-p*, *--pid*='PID'::
|
|
||||||
For operations on the task target, including *--set-handler* with 'TARGET' set
|
|
||||||
to *task*, *--show-task*, and *--show-new-task*, operates on the task associated
|
|
||||||
with process id 'PID' instead of the current task associated with the tool. When
|
|
||||||
this option is supplied, 'COMMAND' must not be specified.
|
|
||||||
+
|
|
||||||
This option uses +task_for_pid()+ to access the process’ task port. This
|
|
||||||
operation may be restricted to use by the superuser, executables signed by an
|
|
||||||
authority trusted by the system, and processes otherwise permitted by
|
|
||||||
taskgated(8). Consequently, this program must normally either be signed or be
|
|
||||||
invoked by root to use this option. It is possible to install this program as a
|
|
||||||
setuid root executable to overcome this limitation.
|
|
||||||
|
|
||||||
*-h*, *--show-host*::
|
|
||||||
Shows the original host exception ports before making any changes requested by
|
|
||||||
*--set-handler*. This option is restricted to the superuser.
|
|
||||||
|
|
||||||
*-t*, *--show-task*::
|
|
||||||
Shows the original task exception ports before making any changes requested by
|
|
||||||
*--set-handler*.
|
|
||||||
|
|
||||||
*--show-thread*::
|
|
||||||
Shows the original thread exception ports before making any changes requested by
|
|
||||||
*--set-handler*.
|
|
||||||
|
|
||||||
*-H*, *--show-new-host*::
|
|
||||||
Shows the modified host exception ports after making any changes requested by
|
|
||||||
*--set-handler*. This option is restricted to the superuser.
|
|
||||||
|
|
||||||
*-T*, *--show-new-task*::
|
|
||||||
Shows the modified task exception ports after making any changes requested by
|
|
||||||
*--set-handler*.
|
|
||||||
|
|
||||||
*--show-new-thread*::
|
|
||||||
Shows the modified thread exception ports after making any changes requested by
|
|
||||||
*--set-handler*.
|
|
||||||
|
|
||||||
*-n*, *--numeric*::
|
|
||||||
For *--show-** options, all values will be displayed numerically only. The
|
|
||||||
default is to decode numeric values and display them symbolically as well.
|
|
||||||
|
|
||||||
*--help*::
|
|
||||||
Display help and exit.
|
|
||||||
|
|
||||||
*--version*::
|
|
||||||
Output version information and exit.
|
|
||||||
|
|
||||||
== Examples
|
|
||||||
|
|
||||||
Sets a new task-level exception handler for +EXC_CRASH+-type exceptions to the
|
|
||||||
handler registered with the bootstrap server as +svc+, showing the task-level
|
|
||||||
exception ports before and after the change. The old and new exception handlers
|
|
||||||
are verified by their service names as registered with the bootstrap server.
|
|
||||||
With the new task-level exception ports in effect, a program is run.

# exception_port_tool(1)
|
||||||
|
|
||||||
|
## Name
|
||||||
|
|
||||||
|
exception_port_tool—Show and change Mach exception ports
|
||||||
|
|
||||||
|
## Synopsis
|
||||||
|
|
||||||
|
**exception_port_tool** [_OPTION…_] [_COMMAND_ [_ARG…_]]
|
||||||
|
|
||||||
|
## Description
|
||||||
|
|
||||||
|
Shows Mach exception ports registered for a thread, task, or host target with a
|
||||||
|
__--show-*__ option, changes Mach exception ports with **--set-handler**, shows
|
||||||
|
changes with a __--show-new-*__ option, and executes _COMMAND_ along with any
|
||||||
|
arguments specified (_ARG…_) with the changed exception ports in effect.
|
||||||
|
|
||||||
|
## Options
|
||||||
|
|
||||||
|
* **-s**, **--set-handler**=_DESCRIPTION_
|
||||||
|
|
||||||
|
Set an exception port to _DESCRIPTION_. This option may appear zero, one, or
|
||||||
|
more times.
|
||||||
|
|
||||||
|
_DESCRIPTION_ is formatted as a comma-separated sequence of tokens, where
|
||||||
|
each token consists of a key and value separated by an equals sign. These
|
||||||
|
keys are recognized:
|
||||||
|
|
||||||
|
* **target**=_TARGET_
|
||||||
|
|
||||||
|
_TARGET_ defines which target’s exception ports to set: **host**,
|
||||||
|
**task**, or **thread**. The default value of _TARGET_ is **task**.
|
||||||
|
Operations on **host** are restricted to the superuser.
|
||||||
|
|
||||||
|
* **mask**=_MASK_
|
||||||
|
|
||||||
|
_MASK_ defines the mask of exception types to handle, from
|
||||||
|
`<mach/exception_types.h>`. This can be **BAD_ACCESS**,
|
||||||
|
**BAD_INSTRUCTION**, **ARITHMETIC**, **EMULATION**, **SOFTWARE**,
|
||||||
|
**BREAKPOINT**, **SYSCALL**, **MACH_SYSCALL**, **RPC_ALERT**, **CRASH**,
|
||||||
|
**RESOURCE**, **GUARD**, or **CORPSE_NOTIFY**. Different exception types
|
||||||
|
may be combined by combining them with pipe characters (**|**). The
|
||||||
|
special value **ALL** includes each exception type except for **CRASH**
|
||||||
|
and **CORPSE_NOTIFY**. To truly specify all exception types including
|
||||||
|
these, use **ALL|CRASH|CORPSE_NOTIFY**. The default value of _MASK_ is
|
||||||
|
**CRASH**.
|
||||||
|
|
||||||
|
* **behavior**=_BEHAVIOR_
|
||||||
|
|
||||||
|
_BEHAVIOR_ defines the specific exception handler routine to be called
|
||||||
|
when an exception occurs. This can be **DEFAULT**, **STATE**, or
|
||||||
|
**STATE_IDENTITY**. **MACH** may also be specified by combining them with
|
||||||
|
pipe characters (**|**). The most complete set of exception information is
|
||||||
|
provided with **STATE_IDENTITY|MACH**. Not all exception servers implement
|
||||||
|
all possible behaviors. The default value of _BEHAVIOR_ is
|
||||||
|
**DEFAULT|MACH**.
|
||||||
|
|
||||||
|
* **flavor**=_FLAVOR_
|
||||||
|
|
||||||
|
For state-carrying values of _BEHAVIOR_ (those including **STATE** or
|
||||||
|
**STATE_IDENTITY**), _FLAVOR_ specifies the architecture-specific thread
|
||||||
|
state flavor to be provided to the exception handler. For the x86 family,
|
||||||
|
this can be **THREAD**, **THREAD32**, **THREAD64**, **FLOAT**,
|
||||||
|
**FLOAT32**, **FLOAT64**, **DEBUG**, **DEBUG32**, or **DEBUG64**. The
|
||||||
|
default value of _FLAVOR_ is **NONE**, which is not valid for
|
||||||
|
state-carrying values of _BEHAVIOR_.
|
||||||
|
|
||||||
|
* **handler**=_HANDLER_
|
||||||
|
|
||||||
|
_HANDLER_ defines the exception handler. **NULL** indicates that any
|
||||||
|
existing exception port should be cleared. _HANDLER_ may also take the
|
||||||
|
form **bootstrap**:_SERVICE_, which will look _SERVICE_ up with the
|
||||||
|
bootstrap server and set that service as the exception handler. The
|
||||||
|
default value of _HANDLER_ is **NULL**.
|
||||||
|
|
||||||
|
* **--show-bootstrap**=_SERVICE_
|
||||||
|
|
||||||
|
Looks up _SERVICE_ with the bootstrap server and shows it. Normally, the
|
||||||
|
handler port values displayed by the other __--show-*__ options are
|
||||||
|
meaningless handles, but by comparing them to the port values for known
|
||||||
|
bootstrap services, it is possible to verify that they are set as intended.
|
||||||
|
|
||||||
|
* **-p**, **--pid**=_PID_
|
||||||
|
|
||||||
|
For operations on the task target, including **--set-handler** with _TARGET_
|
||||||
|
set to **task**, **--show-task**, and **--show-new-task**, operates on the
|
||||||
|
task associated with process id _PID_ instead of the current task associated
|
||||||
|
with the tool. When this option is supplied, _COMMAND_ must not be specified.
|
||||||
|
|
||||||
|
This option uses `task_for_pid()` to access the process’ task port. This
|
||||||
|
operation may be restricted to use by the superuser, executables signed by an
|
||||||
|
authority trusted by the system, and processes otherwise permitted by
|
||||||
|
taskgated(8). Consequently, this program must normally either be signed or be
|
||||||
|
invoked by root to use this option. It is possible to install this program as
|
||||||
|
a setuid root executable to overcome this limitation. However, it is not
|
||||||
|
possible to use this option to operate on processes protected by [System
|
||||||
|
Integrity Protection (SIP)](https://support.apple.com/HT204899), including
|
||||||
|
those whose “restrict” codesign(1) option is respected.
|
||||||
|
|
||||||
|
* **-h**, **--show-host**
|
||||||
|
|
||||||
|
Shows the original host exception ports before making any changes requested
|
||||||
|
by **--set-handler**. This option is restricted to the superuser.
|
||||||
|
|
||||||
|
* **-t**, **--show-task**
|
||||||
|
|
||||||
|
Shows the original task exception ports before making any changes requested
|
||||||
|
by **--set-handler**.
|
||||||
|
|
||||||
|
* **--show-thread**
|
||||||
|
|
||||||
|
Shows the original thread exception ports before making any changes requested
|
||||||
|
by **--set-handler**.
|
||||||
|
|
||||||
|
* **-H**, **--show-new-host**
|
||||||
|
|
||||||
|
Shows the modified host exception ports after making any changes requested by
|
||||||
|
**--set-handler**. This option is restricted to the superuser.
|
||||||
|
|
||||||
|
* **-T**, **--show-new-task**
|
||||||
|
|
||||||
|
Shows the modified task exception ports after making any changes requested by
|
||||||
|
**--set-handler**.
|
||||||
|
|
||||||
|
* **--show-new-thread**
|
||||||
|
|
||||||
|
Shows the modified thread exception ports after making any changes requested
|
||||||
|
by **--set-handler**
|
||||||
|
|
||||||
|
* **-n**, **--numeric**
|
||||||
|
|
||||||
|
For __--show-*__ options, all values will be displayed numerically only. The
|
||||||
|
default is to decode numeric values and display them symbolically as well.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.
|
||||||
|
|
||||||
|
* **--version**
|
||||||
|
|
||||||
|
Output version information and exit.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
Sets a new task-level exception handler for `EXC_CRASH`-type exceptions to the
|
||||||
|
handler registered with the bootstrap server as `svc`, showing the task-level
|
||||||
|
exception ports before and after the change. The old and new exception handlers
|
||||||
|
are verified by their service names as registered with the bootstrap server.
|
||||||
|
With the new task-level exception ports in effect, a program is run.
|
||||||
|
|
||||||
|
```
|
||||||
|
$ exception_port_tool --show-task --show-new-task \
|
||||||
|
--show-bootstrap=com.apple.ReportCrash --show-bootstrap=svc \
|
||||||
|
--set-handler=behavior=DEFAULT,handler=bootstrap:svc crash
|
||||||
|
service com.apple.ReportCrash 0xe03
|
||||||
|
service svc 0x1003
|
||||||
|
task exception port 0, mask 0x400 (CRASH), port 0xe03, behavior 0x80000003 (STATE_IDENTITY|MACH), flavor 7 (THREAD)
|
||||||
|
new task exception port 0, mask 0x400 (CRASH), port 0x1003, behavior 0x1 (DEFAULT), flavor 13 (NONE)
|
||||||
|
Illegal instruction: 4
|
||||||
|
```
|
||||||
|
|
||||||
|
Shows the task-level exception ports for the process with PID 1234. This
|
||||||
|
requires superuser permissions or the approval of taskgated(8), and the process
|
||||||
|
must not be SIP-protected.
|
||||||
|
|
||||||
|
```
|
||||||
|
# exception_port_tool --pid=1234 --show-task
|
||||||
|
task exception port 0, mask 0x4e (BAD_ACCESS|BAD_INSTRUCTION|ARITHMETIC|BREAKPOINT), port 0x1503, behavior 0x1 (DEFAULT), flavor 13 (NONE)
|
||||||
|
task exception port 1, mask 0x1c00 (CRASH|RESOURCE|GUARD), port 0x1403, behavior 0x80000003 (STATE_IDENTITY|MACH), flavor 7 (THREAD)
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
== Description
|
|
||||||
|
|
||||||
On-demand services may be registered with launchd(8) by using the *--load* form.
|
|
||||||
One or more service names may be registered with the bootstrap server by
|
|
||||||
specifying *--mach-service*. When a Mach message is sent to any of these
|
|
||||||
services, launchd(8) will invoke 'COMMAND' along with any arguments specified
|
|
||||||
('ARG…'). 'COMMAND' must be an absolute pathname.
|
|
||||||
|
|
||||||
The *--unload* form unregisters jobs registered with launchd(8).
|
|
||||||
|
|
||||||
== Options
|
|
||||||
|
|
||||||
*-L*, *--load*::
|
|
||||||
Registers a job with launchd(8). *--label*='LABEL' and 'COMMAND' are required.
|
|
||||||
This operation may also be referred to as “load” or “submit”.
|
|
||||||
|
|
||||||
*-U*, *--unload*::
|
|
||||||
Unregisters a job with launchd(8). *--label*='LABEL' is required. This operation
|
|
||||||
may also be referred to as “unload” or “remove”.
|
|
||||||
|
|
||||||
*-l*, *--label*='LABEL'::
|
|
||||||
'LABEL' is used as the job label to identify the job to launchd(8). 'LABEL' must
|
|
||||||
be unique within a launchd(8) context.
|
|
||||||
|
|
||||||
*-m*, *--mach-service*='SERVICE'::
|
|
||||||
In conjunction with *--load*, registers 'SERVICE' with the bootstrap server.
|
|
||||||
Clients will be able to obtain a send right by looking up the 'SERVICE' name
|
|
||||||
with the bootstrap server. When a message is sent to such a Mach port,
|
|
||||||
launchd(8) will invoke 'COMMAND' along with any arguments specified ('ARG…') if
|
|
||||||
it is not running. This forms the “on-demand” nature referenced by this tool’s
|
|
||||||
name. This option may appear zero, one, or more times. 'SERVICE' must be unique
|
|
||||||
within a bootstrap context.
|

## Description
|
||||||
|
|
||||||
|
On-demand services may be registered with launchd(8) by using the **--load**
|
||||||
|
form. One or more service names may be registered with the bootstrap server by
|
||||||
|
specifying **--mach-service**. When a Mach message is sent to any of these
|
||||||
|
services, launchd(8) will invoke _COMMAND_ along with any arguments specified
|
||||||
|
(_ARG…_). _COMMAND_ must be an absolute pathname.
|
||||||
|
|
||||||
|
The **--unload** form unregisters jobs registered with launchd(8).
|
||||||
|
|
||||||
|
## Options
|
||||||
|
|
||||||
|
* **-L**, **--load**
|
||||||
|
|
||||||
|
Registers a job with launchd(8). **--label**=_LABEL_ and _COMMAND_ are
|
||||||
|
required. This operation may also be referred to as “load” or “submit”.
|
||||||
|
|
||||||
|
* **-U**, **--unload**
|
||||||
|
|
||||||
|
Unregisters a job with launchd(8). **--label**=_LABEL_ is required. This
|
||||||
|
operation may also be referred to as “unload” or “remove”.
|
||||||
|
|
||||||
|
* **-l**, **--label**=_LABEL_
|
||||||
|
|
||||||
|
_LABEL_ is used as the job label to identify the job to launchd(8). _LABEL_
|
||||||
|
must be unique within a launchd(8) context.
|
||||||
|
|
||||||
|
* **-m**, **--mach-service**=_SERVICE_
|
||||||
|
|
||||||
|
In conjunction with **--load**, registers _SERVICE_ with the bootstrap
|
||||||
|
server. Clients will be able to obtain a send right by looking up the
|
||||||
|
_SERVICE_ name with the bootstrap server. When a message is sent to such a
|
||||||
|
Mach port, launchd(8) will invoke _COMMAND_ along with any arguments
|
||||||
|
specified (_ARG…_) if it is not running. This forms the “on-demand” nature
|
||||||
|
referenced by this tool’s name. This option may appear zero, one, or more
|
||||||
|
times. _SERVICE_ must be unique within a bootstrap context.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.
|
||||||
|
|
||||||
|
* **--version**
|
||||||
|
|
||||||
|
Output version information and exit.
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
Registers an on-demand server that will execute
|
||||||
|

|
|
||||||
|
|
||||||
== Name
|
|
||||||
|
|
||||||
run_with_crashpad - Run a program with a Crashpad exception handler
|
|
||||||
|
|
||||||
== Synopsis
|
|
||||||
|
|
||||||
[verse]
|
|
||||||
*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 option’s 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.

## 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)](../../handler/crashpad_handler.md) 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_

||||||
|
|
||||||
|
* **-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 option’s presence, the handler will always
|
||||||
|
be invoked with the necessary arguments to perform a handshake.
|
||||||
|
|
||||||
|
* **--help**
|
||||||
|
|
||||||
|
Display help and exit.
|
||||||
|
|
||||||
