post

rbt post simplifies both creating and updating review requests. It can look at your source directory, generate a diff, and upload it to a new or existing review request on an associated Review Board server. This saves a lot of time over the web UI, and for some types of code repositories (such as Perforce), it’s actually required in order to produce a compatible diff.

Usage

$ rbt post [options] [revisions]

Posting and Updating Review Requests

Depending on the repository type, rbt post will either require a changeset number, or it will rely on the changes in the current source tree. The end result is that rbt post will build a diff and post it to a Review Board server. The diff and any additional review request information will be saved on the server as a draft, which can then be published.

After posting a new review request or updating an existing one, rbt post will display the URL of the review request. If the -o parameter is passed, the default web browser will be opened to that URL.

The following subsections will explain how rbt post is used with different repository types.

Perforce

Posting Changesets

Perforce has a concept of changesets, which are server-stored descriptions of a change along with an ID number and associated files. For Perforce, Review Board stores changeset numbers of a posted change and can use these to associate particular changes with review requests.

To post a review request for a specific change, or to update an existing review request for that change, type:

$ rbt post CHANGENUM

Where CHANGENUM is a pending or shelved changeset number in Perforce.

Note

When CHANGENUM refers to a shelved changeset which does not have opened files in the client, any moved files within the change will be shown as a deleted file and an added file. This is due to limitations in Perforce’s interface for shelved changesets.

The diff will be generated and uploaded to Review Board, and the review request information will be updated based on the changeset description.

rbt post must be used if you’re using Perforce with Review Board, as the diff generated by p4 diff doesn’t provide the information necessary to properly display a side-by-side diff.

Posting Paths

There are cases where you may want to post individual paths containing files instead of changesets. Take the following cases, for example:

  • You have code or other files that must be checked in before they’re reviewed and have undergone multiple changes.
  • You’re working in a side branch for a while, possibly with other people, and need to review the code before it’s integrated into the main branch.
  • You want to post a really old, previously abandoned change for review that previously went unreviewed.

To post with a path, rbt post should be run with a standard Perforce depot path as a parameter, which may contain revision information. The following paths are supported:

Uploading a file as a “new” file:

//path/to/file

Uploading all files in a directory as “new” files:

//path/to/dir/...

Uploading a file from a revision as a “new” file (not as common):

//path/to/file/[@#]rev

Uploading a diff of a file between two revisions:

//path/to/file[@#]rev,[@#]rev

Uploading a diff of all files between two revisions in a directory:

//path/to/dir/...[#@]rev,[#@]rev

CVS and Subversion

CVS and Subversion don’t have a concept of changesets, so instead the working copy’s uncommitted changes are posted for review. To post a review request with all uncommitted files in a tree, simply run:

$ rbt post

This will create a new review request and post the diff of the uncommitted changes. If you want to update an existing review request with new changes instead, use the -r parameter. For example, to update review request #42, type:

$ rbt post -r 42

If you need to post specific files, leaving other uncommitted files out of the review request, you can include them on the command line, like so:

$ rbt post -I src/foo.c -I data/bar.png

Distributed Version Control Systems

When using a distributed version control system, such as Git or Mercurial, rbt post will by default post the diff between the current branch and the master branch. To post a new review request with the diff between the current branches commit, and the master branch, simply run:

$ rbt post

If you’d like to update an existing review request with new changes instead, use the -r parameter. For example, to update review request #42, type:

$ rbt post -r 42

You can also use the -u parameter to automatically determine the existing review request based on the patch summary and description:

$ rbt post -u

Additionally, rbt post can generate a summary and description for your review request based on the commit messages from the involved commits. This is accomplished using the -g parameter. To post a new review request with a generated summary and description, simply run:

$ rbt post -g

In the case where you are working on code based on a branch that isn’t available to the repository Review Board has configured, you’ll want to take advantage of rbt post‘s parent diff support.

A parent diff is a diff between some known upstream revision that Review Board has access to and the parent of your branch. It’s used to provide a working baseline for your branch’s diff.

For example, in the case of Git, you may be working on the topicB branch, which has an ancestry that looks like:

o master
 \
  o---o topicA
       \
        o---o topicB

If you want to upload a diff of everything between topicA and topicB, you would need to tell rbt post to also generate a parent diff between master and topicA.

This is done by using the --parent parameter with the branch name. For example, in this case you would simply do:

$ rbt post --parent=topicA

That would generate a parent diff between master and topicA, and a normal diff of your changes between topicA and topicB. The changes in the parent diff won’t appear as changed lines in the diff viewer, meaning that users will only see changes made between topicB and topicA.

Tracking Branches

When using Git, rbt post makes the assumption that the closest upstream branch for the diff will be origin/master. This may be wrong if you are working on a feature branch or have a remote named something other than origin.

In this case, you will want to use the --tracking-branch option, which specifies the remote branch name. For example:

$ rbt post --tracking-branch=upstream/master

ClearCase

Changed in version 0.6: ClearCase support used to use the --tracking-branch and --revision-range options for specifying branches and manual changesets, respectively. As of version 0.6, these are just passed in as arguments.

rbt post provides basic support for posting ClearCase reviews. If you want to post a review of all currently checked out files in your view simply run:

rbt post

If you collect changesets, for example, using ClearCase/ClearQuest integration, you can pass the changeset in as arguments. Each argument will be an file@@revision1:file@@revision2 pair:

$ rbt post /vobs/proj/file.c@@/main/0:/vobs/proj/file.c@@/main/1

Multiple files can be posted by adding additional file/revision pairs:

$ rbt post /vobs/proj/file.c@@/main/0:/vobs/proj/file.c@@/main/1 /vobs/proj/file.h@@/main/0:/vobs/proj/file.h@@/main/1

Another way for post-commit review is send changes developed on branch by specifying the branch name with a brtype: prefix:

$ rbt post brtype:my_dev_branch

Note

rbt post tries to match Review Board’s repository based on the VOB’s UUID. If this doesn’t work, the VOB’s name will be used. If you need to override this behavior, you can use the REPOSITORY or REPOSITORY_URL settings in .reviewboardrc or pass the --repository or --repository-url command-line options.

Posting Committed Code

By default, rbt post assumes that you’re posting uncommitted code. This is called a pre-commit review. However, it’s sometimes useful to post code that has already been committed to a repository, such as in an experimental branch. This is a post-commit review.

In order to do this, you can pass in revisions as arguments, which will generate a diff based on a range of committed revisions. This allows a single review request to show a diff representing the entire history of a branch, if desired.

Usage is easy. Simply type:

$ rbt post STARTREV STOPREV

Where STARTREV is the beginning revision in the range, and STOPREV is the ending revision, inclusive. If you only need to post a single revision, you can type:

$ rbt post REVISION

The syntax for revisions and revision ranges is as close to possible as the native syntax for the underlying revision control system. You can therefore pass in ranges either as separate arguments, or using a native range syntax (such as R1:R2 for SVN or R1..R2 for Git).

Posting Existing Diffs

rbt post will generate diffs automatically based on the repository type, but if you need to post a pre-existing diff, you can use the --diff-filename parameter to specify the path to the diff file.

For example:

$ rbt post --diff-filename=mycode.diff

You can also use the special value of - to pipe a diff into STDIN:

$ cat mycode.diff | rbt post --diff-filename=-

Using STDIN will require either a valid cookie, or the --username and --password options.

Auto-Setting Summary and Description

The summary and description of a review request can be automatically set (“guessed”) based on the posted commit by using the -g/--guess-fields, --guess-summary, or --guess-description options.

This saves some time when creating a review request by allowing you to write a thorough summary and description only once in the commit, and reusing it for the review request.

This feature only works for SCMs where you’re posting commits, instead of changes from a working directory. For example, Git, Mercurial and Bazaar.

Tip

-g/--guess-fields implies --guess-summary and --guess-description. Generally, you’ll want to use it instead of the more specific options.

Controlling Guessing Behavior

New in version 0.6.

The guessing options can each take a value to control when guessing is done:

  • yes – Guessing will be used when creating or updating the review request.
  • no – Guessing will not be used. This is useful for overriding a default (see Configuring Defaults).
  • auto – Guessing will be used only if creating a new review request, and not when updating.

You can specify a value when using either short-form or long-form arguments. For example:

$ rbt post --guess-fields=no

By default, if no guessing options are specified, --guess-fields=auto will be implied. This allows you to run the following and have it automatically fill in the summary and description:

$ rbt post

If specifying a guessing argument without a value, yes will be implied instead, forcing the fields to be updated, regardless of the default. For example:

$ rbt post -g

Configuring Defaults

Changed in version 0.6.

Projects that want to change the default guess behavior can set the GUESS_FIELDS, GUESS_SUMMARY, and GUESS_DESCRIPTION settings in .reviewboardrc. These accept 'yes', 'no', and 'auto' values.

On RBTools 0.6 or higher, the default is 'auto'. On older versions, the default was False (equivalent to 'no').

Setting GUESS_FIELDS will imply setting GUESS_SUMMARY and GUESS_DESCRIPTION. Rarely will you need to set anything but GUESS_FIELDS.

For example, to default to guessing fields for review requests that are either newly created or being updated, you can use:

GUESS_FIELDS = 'yes'

Automating rbt post

It’s possible to automate rbt post on a user’s behalf. This can be useful from a repository’s post-commit hook to automatically create or update a review request. This works through a combination of a special Review Board user and the --submit-as option.

To set this up, first register a new user. This user will be specific to your script, and will have special permissions, so make sure the password is protected. You’ll then want to grant the “Can submit as user” Permission and “Can edit review request” Permission to the user. This will give this user to the ability to modify a review request as another user.

You can then invoke rbt post by doing the following:

$ rbt post --username=SPECIAL_USER --password=PASSWORD --submit-as=ANOTHER_USER

Of course, you can pass any other values as you see fit.

This will log in as SPECIAL_USER and perform operations as ANOTHER_USER.

You can set the default for --submit-as by setting SUBMIT_AS in .reviewboardrc.

Options

-d, --debug

Displays debug output.

This information can be valuable when debugging problems running the command.

The default can be set in DEBUG in .reviewboardrc.

Posting Options

-u, --update

Automatically determines the existing review request to update.

New in version 0.5.3.

-r <id>, --review-request-id <id>

Specifies the existing review request ID to update.

-p, --publish

Publishes the review request immediately after posting.

All required fields must already be filled in on the review request or must be provided when posting.

The default can be set in PUBLISH in .reviewboardrc.

-t, --trivial-publish

Publish the review request immediately after posting, but without sending an e-mail notification.

New in version 0.8.0.

-o, --open

Opens a web browser to the review request after posting.

The default can be set in OPEN_BROWSER in .reviewboardrc.

-s, --stamp

Stamps the commit message with the review request URL while posting the review.

The default can be set in STAMP_WHEN_POSTING in .reviewboardrc.

New in version 0.7.3.

--submit-as <username>

The username to use as the author of the review request, instead of the logged in user.

This is useful when used in a repository’s post-commit script to update or create review requests. See Automating rbt post for more information on this use case.

The default can be set in SUBMIT_AS in .reviewboardrc.

--change-only

Updates fields from the change description, but does not upload a new diff (Perforce/Plastic only).

--diff-only

Uploads a new diff, but does not update fields from the change description (Perforce/Plastic only).

Review Board Server Options

Options necessary to communicate and authenticate with a Review Board server.

--server <url>

Specifies the Review Board server to use.

The default can be set in REVIEWBOARD_URL in .reviewboardrc.

--username <username>

The user name to be supplied to the Review Board server.

The default can be set in USERNAME in .reviewboardrc.

--password <password>

The password to be supplied to the Review Board server.

The default can be set in PASSWORD in .reviewboardrc.

--ext-auth-cookies <ext auth cookies>

Use an external cookie store with pre-fetched authentication data. This is useful with servers that require extra web authentication to access Review Board, e.g. on single sign-on enabled sites.

The default can be set in EXT_AUTH_COOKIES in .reviewboardrc.

New in version 0.7.5.

--api-token <token>

The API token to use for authentication, instead of using a username and password.

The default can be set in API_TOKEN in .reviewboardrc.

New in version 0.7.

The default can be set in DISABLE_SSL_VERIFICATION in .reviewboardrc.

New in version 0.7.3.

--disable-cookie-storage

Use an in-memory cookie store instead of writing them to a file. No credentials will be saved or loaded.

The default can be set in SAVE_COOKIES in .reviewboardrc.

New in version 0.7.3.

--disable-cache

Disable the HTTP cache completely. This will result in slower requests.

The default can be set in DISABLE_CACHE in .reviewboardrc.

New in version 0.7.3.

Repository Options

--repository <name>

The name of the repository configured on Review Board that matches the local repository.

The default can be set in REPOSITORY in .reviewboardrc.

--repository-url <url>

The URL for a repository.

When generating diffs, this can be used for creating a diff outside of a working copy (currently only supported by Subversion with specific revisions or --diff-filename, and by ClearCase with relative paths outside the view).

For Git, this specifies the origin URL of the current repository, overriding the origin URL supplied by the client.

The default can be set in REPOSITORY_URL in .reviewboardrc.

Changed in version 0.6: Prior versions used the REPOSITORY setting in .reviewboardrc, and allowed a repository name to be passed to --repository-url. This is no longer supported in 0.6 and higher. You may need to update your configuration and scripts appropriately.

--repository-type <type>

The type of repository in the current directory. In most cases this should be detected automatically, but some directory structures containing multiple repositories require this option to select the proper type. The rbt list-repo-types command can be used to list the supported values.

The default can be set in REPOSITORY_TYPE in .reviewboardrc.

Review Request Field Options

Options for setting the contents of fields in the review request.

-f <field name=value>, --field <field name=value>

Sets custom fields into the extra_data of a review request. Can also be used to set built-in fields like description, summary, testing-done.

-g [auto|yes|no], --guess-fields [auto|yes|no]

Equivalent to setting both --guess-summary and --guess-description.

This can optionally take a value to control the guessing behavior. See Controlling Guessing Behavior for more information.

If not specified, auto is used by default. The default can be changed by setting GUESS_FIELDS in .reviewboardrc.

--guess-summary <auto|yes|no>

Generates the Summary field based on the commit messages (Bazaar/Git/Mercurial only).

This can optionally take a value to control the guessing behavior. See Controlling Guessing Behavior for more information.

The default can be set in GUESS_SUMMARY in .reviewboardrc.

--guess-description <auto|yes|no>

Generates the Description field based on the commit messages (Bazaar/Git/Mercurial only).

This can optionally take a value to control the guessing behavior. See Controlling Guessing Behavior for more information.

The default can be set in GUESS_DESCRIPTION in .reviewboardrc.

-m <text>, --change-description <text>

A description of what changed in this update of the review request. This is ignored for new review requests.

--summary <text>

The new contents for the Summary field.

--description <text>

The new contents for the Description field.

--description-file <filename>

A text file containing the new contents for the Description field.

--testing-done <text>

The new contents for the Testing Done field.

--testing-done-file <filename>

A text file containing the new contents for the Testing Done field.

--branch <branch>

The branch the change will be committed on or affects. This is a free-form field and does not control any behavior.

The default can be set in BRANCH in .reviewboardrc.

--bugs-closed <bug id[,...]>

The comma-separated list of bug IDs closed.

--target-groups <name[,...]>

The names of the groups that should perform the review.

The default can be set in TARGET_GROUPS in .reviewboardrc.

--target-people <username[,...]>

The usernames of the people who should perform the review.

The default can be set in TARGET_PEOPLE in .reviewboardrc.

--depends-on <id[,...]>

A comma-separated list of review request IDs that this review request will depend on.

The default can be set in DEPENDS_ON in .reviewboardrc.

New in version 0.6.1.

--markdown

Specifies if the summary, description, and change description should should be interpreted as Markdown-formatted text.

This is only supported in Review Board 2.0+.

The default can be set in MARKDOWN in .reviewboardrc.

New in version 0.6.

Diff Generation Options

Options for choosing what gets included in a diff, and how the diff is generated.

--revision-range <rev1:rev2>

Generates a diff for the given revision range.

Deprecated since version 0.6.

-I <filename>, --include <filename>

Includes only the specified file in the diff. This can be used multiple times to specify multiple files.

Supported by: Bazaar, CVS, Git, Mercurial, Perforce, and Subversion.

New in version 0.6.

-X <pattern>, --exclude <pattern>

Excludes all files that match the given pattern from the diff. This can be used multiple times to specify multiple patterns. UNIX glob syntax is used for pattern matching.

Supported by: Bazaar, CVS, Git, Mercurial, Perforce, and Subversion.

Patterns that begin with a path separator (/ on Mac OS and Linux, on Windows) will be treated as being relative to the root of the repository. All other patterns are treated as being relative to the current working directory.

For example, to exclude all ”.txt” files from the resulting diff, you would use “-X /’*.txt’”.

When working with Mercurial, the patterns are provided directly to “hg” and are not limited to globs. For more information on advanced pattern syntax in Mercurial, run “hg help patterns”

When working with CVS all diffs are generated relative to the current working directory so patterns beginning with a path separator are treated as relative to the current working directory.

When working with Perforce, an exclude pattern beginning with // will be matched against depot paths; all other patterns will be matched against local paths.

The default can be set in EXCLUDE_PATTERNS in .reviewboardrc.

New in version 0.7.

--parent <branch>

The parent branch this diff should be generated against (Bazaar/Git/Mercurial only).

The default can be set in PARENT_BRANCH in .reviewboardrc.

--diff-filename <filename>

Uploads an existing diff file, instead of generating a new diff.

Branch Options

Options for selecting branches.

--tracking-branch <branch>

The remote tracking branch from which your local branch is derived (Git/Mercurial only).

For Git, the default is origin/master.

For Mercurial, the default is one of: reviewboard, origin, parent, or default.

The default can be set in TRACKING_BRANCH in .reviewboardrc.

Perforce Options

Perforce-specific options for selecting the Perforce client and communicating with the repository.

--p4-client <client name>

The Perforce client name for the repository.

The default can be set in P4_CLIENT in .reviewboardrc.

The IP address for the Perforce server.

The default can be set in P4_PORT in .reviewboardrc.

--p4-passwd <password>

The Perforce password or ticket of the user in the P4USER environment variable.

The default can be set in P4_PASSWD in .reviewboardrc.

Subversion Options

Subversion-specific options for controlling diff generation.

--basedir <path>

The path within the repository where the diff was generated. This overrides the detected path. Often used when passing --diff-filename.

The default can be set in BASEDIR in .reviewboardrc.

--svn-username <username>

The username for the SVN repository.

--svn-password <password>

The password for the SVN repository.

--svn-prompt-password

Prompt for the user’s svn password. This option overrides the password provided by the --svn-password option.

The default can be set in SVN_PROMPT_PASSWORD in .reviewboardrc.

New in version 0.7.3.

--svn-show-copies-as-adds <y|n>

Treat copied or moved files as new files.

This is only supported in Subversion 1.7+.

New in version 0.5.2.

--svn-changelist <id>

Generates the diff for review based on a local changelist.

Deprecated since version 0.6.

TFS Options

Team Foundation Server specific options for communicating with the TFS server.

--tf-cmd <tf cmd>

The full path of where to find the tf command. This overrides any detected path.

The default can be set in TF_CMD in .reviewboardrc.

--tfs-shelveset-owner <tfs shelveset owner>

When posting a shelveset name created by another user (other than the one who owns the current workdir), look for that shelveset using this username.
