Phabricator review submission/management tool.
Project description
Wrapper around Phabricator's arc cli to support submission of a series of commits.
Installation
moz-phab can be installed with pip install MozPhab.
For detailed installation instructions please see:
Configuration
moz-phab has an INI style configuration file to control defaults: ~/.moz-phab-config
This file will be created if it doesn't exist.

ui.no_ansi: never use ANSI colours (default: auto-detected).vcs.safe_mode: use only safe VCS settings (default: false). Use--safe-modeoption to switch it on for a one-time usage.git.remote: comma separated string. Default remotes used to find the first unpublished commit. Default, empty string, means that a list of remotes will be read fromgit remotecommand.submit.auto_submit: when true the confirmation prompt will be skipped (default: false).submit.always_blocking: when true reviewers in commit descriptions will be marked as blocking. reviewers specified on the command line override this setting (default: false).submit.warn_untracked: when true show a warning if there are uncommitted or untracked changes in the working directory (default: true)patch.apply_to: [base/here] Where to apply the patches by default. If"base"moz-phabwill look for the SHA1 in the first commit. If"here"- current commit/checkout will be used (default: base).patch.create_bookmark: affects only when patching a Mercurial repository. IfTruemoz-phabwill create a bookmark (based on the last revision number) for the new DAG branch point.patch.always_full_stack: whenFalseand the patched revision has successors, moz-phab will ask if the whole stack should be patched instead. IfTruemoz-phab will do it without without asking.updater.self_last_check: epoch timestamp (local timezone) indicating the last time an update check was performed for this script. set to-1to disable this check.updater.arc_last_check: epoch timestamp (local timezone) indicating the last time an update was performed for arc. set to-1to disable this check.
moz-phab can also be configured via the following environmental variables:
DEBUG: enabled debugging output (default: disabled)UPDATE_FILE: when self-updating write to this file instead of __file__
Execution
To get information about all available commands run
$ moz-phab -h
All commands involving VCS (like submit and patch) might be used with a
--safe-mode switch. It will run the VCS command with only chosen set of extensions.
Submitting commits to the Phabricator
The simplest invocation is
$ moz-phab [start_rev] [end_rev]
If no positional arguments (start_rev/end_rev) are given, the
range of commits is automatically determined, starting with the first
non-public, non-obsolete changeset (for Mercurial) or first unpublished commit
(for Git) and ending with the currently checked-out changeset. If at least one
argument is given moz-phab is following the underlying VCS's log behavior.
The first argument is interpreted differently in Mercurial (as inclusive) and
Git (exclusive). If only one argument is given the end of range is again
interpreted as the currently checked-out changeset. If both arguments are
given - the second one is interpreted as inclusive.
Bug IDs and reviewers are parsed out of commit messages by default.
You can set a reviewer as blocking by appending an exclamation mark to
the reviewer's nick, e.g. r=foo!. If submit.always_blocking is
set to true (see above), reviewers will always be set to blocking
regardless.
A bug ID can also be set for every revision in the series with the
--bug option, which overrides any bug IDs in commit messages.
Similarly, reviewers can be set for every revision in the series
with --reviewer (regular reviewers) and/or --blocker (blocking
reviewers), which again overrides any reviewers in commit messages.
Run moz-phab submit -h for more options for submitting revisions.
To submit updates to a commit series, run moz-phab in the same way
with the same arguments, that is, specifying the full original range
of commits. Note that, while inserting and amending commits should
work fine, reordering commits is not yet supported, and deleting
commits will leave the associated revisions open, which should be
abandoned manually. See
bug 1481539 for
planned fixes. Also note that "fix-up" commits are not yet supported;
see bug 1481542.
moz-phab will periodically check for updates and display a notice
when a new version is available. To update moz-phab, run moz-phab self-update.
Note that if you do not have Python in your path, you will need to run
<path to python>/python <path to moz-phab>/moz-phab instead of moz-phab.
Downloading a patch from the Phabricator
moz-phab patch allows patching an entire stack of revisions. The simplest
invocation is
$ moz-phab patch rev_id
To patch a stack ending with the revision D123 run moz-phab patch D123.
Diffs will be downloaded from the Phabricator and applied using the underlying
VCS (import for Mercurial or apply for Git). A commit for each revision will
be created in a new bookmark (Mercurial) or branch (Git).
This behavior can be modified with few options:
-
--apply-to TARGETDefine the commit to which apply the patch:base(default) find the base commit in the first ancestor of the revision,hereuse the current commit,{NODE}use a commit identified by SHA1 or (in Mecurial) revision number
-
--rawPrint out the diffs of each revision starting from the oldest ancestor instead of applying to the repository. It can be used to patch the working directory with an external tool:$ moz-phab patch D123 --raw | patch -p1. -
--no-commitUse thegit applycommand (also for Mercurial repos) to patch the diffs. No commit or branch is created. -
--no-bookmark: used only when patching a Mercurial repository. If not provided -moz-phabwill create a bookmark (based on the last revision number) for the new DAG branch point. The default behavior is configurable. -
--no-branch: used only when patching a Git repository. If not provided -moz-phabwill create a branch (based on the revision number). Otherwise commits will be added just on top of the base commit which might result in switching the repository to the 'detached HEAD' state. -
--skip-dependencies: patch only one revision, ignore dependencies.
Running arc commands
moz-phab arc allows running Arcanist commands indirectly:
$ moz-phab arc ARG [ARG ...]
arc land --preview will become moz-phab arc land --preview.
Reporting Issues
We use Bugzilla to track development.
File bugs in Bugzilla under Conduit :: moz-phab.
Development
We have strict requirements for moz-phab development:
- must only use standard libraries
- must be a single file for easy deployment
Tests can be executed with pytest.
Integration tests require to have access to git, hg with evolve extension
and patch commands.
All python code must be formatted with black using the default settings.
Pull Requests are not accepted here; please submit changes with Phabricator.
