&dhfirstname; &dhsurname; gbp-dch &dhsection; gbp-dch Generate the &debian; changelog from git commit messages &gbp-dch; &man.common.options.synopsis; --debian-branch=branch_name --debian-tag=tag-format --upstream-branch=branch_name --upstream-tag=tag-format --ignore-branch -s commitish --since=commitish -S --snapshot -R --release -N version --new-version=version --bpo --nmu --qa --security --team --distribution=name --force-distribution -U level --urgency=level --[no-]full --[no-]meta --meta-closes=bug-close-tags --meta-closes-bugnum=bug-number-format --snapshot-number=expression --id-length=number --git-log=git-log-options --[no-]git-author --[no-]multimaint --[no-]multimaint-merge --spawn-editor=[always|never|snapshot|release] --commit-msg=msg-format -c --commit --customizations=customization-file --postedit=COMMAND --dch-opt=dch-options --verbose path1 path2 &gbp-dch; reads git commit messages and generates the &debian; changelog from it. It starts at a given commit specified by the --since option up to the current HEAD. For each commit found it adds the commit message to the changelog. If --since is not given the commit to start from is determined by the following rules (first one matches): The start commit is read from the snapshot banner (see below for details) If the topmost version of the debian/changelog is alread tagged. Use the commit the tag points to as start commit. The last commit that modified debian/changelog is used as start commit. This is called automatic mode. If the distribution of the topmost section in debian/changelog is UNRELEASED, the changelog entries will be inserted into this section. Otherwise a new section will be created. If one ore more paths are given as arguments &gbp-dch; will only include changes in debian/changelog that affect these paths. E.g. using debian/ is a good choice if upstream uses &git; and you don't want the upstream history to end up in debian/changelog. To restrict the selected changes even further you can use use the --git-log option which is passed on verbatim to git log. E.g. by using --git-log="--author=Foo Bar". The above relies on the --debian-branch option pointing to the current branch and --upstream-branch pointing to the corresponding upstream branch in order to find the right merge points of these branches. Furthermore &gbp-dch; must be able to identify git tags from upstream and Debian version numbers. If you're not using the defaults check the --upstream-tag and --debian-tag options and make sure they match the tags created by e.g. &gbp-import-orig; (when using tarballs) or upstream's tagging pattern (when using upstream's git directly). If not changelog exists yet it is created and the version number is derived from the last upstream tag if found. &man.common.options.description; --debian-branch=branch_name The branch in the Git repository the Debian package is being developed on, default is master. --upstream-branch=branch_name Branch to determine the upstream version from. Default is upstream. --git-upstream-tag=TAG-FORMAT Use this tag format when looking for tags of upstream versions, default is upstream/%(version)s. --ignore-branch Don't check if the current branch matches debian-branch. --debian-tag=tag-format Tag format used, when tagging debian versions, default is debian/%(version)s --since=committish Start reading commit messages at committish. This option can't be set via &gbp.conf;. --auto, -a This option is ignored for compatibility with older versions. It used to trigger automatic mode. --[no-]meta Parse meta tags like Closes:, Thanks: and Gbp-Dch:. See META TAGS below. --meta-closes=bug-close-tags What meta tags to look for to generate bug-closing changelog entries. The default is 'Closes|LP' to support Debian and Launchpad. --meta-closes-bugnum=bug-number-format What regular expression should be used to parse out the bug number. The default is '(?:bug|issue)?\#?\s?\d+'. Note: the regex should suppress all portions of the bug number that are not wanted using "(?:)", see Python regex manual for details. Example: --meta-closes-bugnum="(?:bug)?\s*ex-\d+" would match all of the following: Possible Txt Match? Result ------------ ------ ------ bug EX-12345 Y EX-12345 ex-01273 Y ex-01273 bug ex-1ab Y ex-1 EX--12345 N --[no-]full Include the full commit message in the changelog output. --snapshot, -S Create a snapshot release entry. It uses a snapshot release number which is smaller than the final release number and adds a warning banner to the changelog entry. The version number is being auto incremented with every new snapshot release. The snapshot banner is also used by &gbp-dch; to determine which entries are already in the changelog. This prevents duplicated entries in debian/changelog when you did not commit the changelog yet. --snapshot-number=expression Python expression that gets eval()ed to the new snapshot number. --release, -R Remove any snapshot release banners and version suffixes (if any), set the current distribution to unstable, and open the changelog for final tweaking. This option can't be set via &gbp.conf;. It's usually used to finalize the changelog before making a release. --new-version=version, -N version Add a new changelog section with version newversion. Together with --snapshot, the snapshot number will be appended to newversion. This option can't be set via &gbp.conf;. --team Create a Team upload changelog entry. This option can't be set via &gbp.conf;. --bpo Increment the Debian release number for an upload to backports, and add a backport upload changelog comment. This option can't be set via &gbp.conf;. --nmu Increment the Debian release number for a non-maintainer upload. This option can't be set via &gbp.conf;. --qa Increment the Debian release number for a Debian QA Team upload, and add a QA upload changelog comment. This option can't be set via &gbp.conf;. --security Increment the Debian release number for a Debian Security Team non-maintainer upload, and add a "Security Team upload" changelog comment. This option can't be set via &gbp.conf;. --distribution=name Set the distribution field to name. This option can't be set via &gbp.conf;. --force-distribution Force the distribution specified with --distribution to be used, even if it doesn't match the list of known distributions. This option can't be set via &gbp.conf;. --urgency=level Set the urgency field to level. --git-log=git-log-options Options passed on verbatim to git-log(1). --id-length=N Include N digits of the commit id in the changelog entry. Default is to not include any commit ids at all. --ignore-regex=regex Ignore commit lines matching regex when generating the changelog. --git-author Use user.name and user.email from git-config(1) for changelog trailer. --[no-]multimaint-merge Merge commits by maintainer. --spawn-editor=[always|never|snapshot|release] Whether to spawn an editor: always, never, when doing snapshots or when doing a release. --commit-msg=msg-format Use this format string for the commit message when committing the generated changelog file (when --commit is given). Default is Update changelog for %(version)s release --commit Commit the generated changelog. --customizations=customization-file Load Python code from customization-file. At the moment, the only useful thing the code can do is define a custom format_changelog_entry() function. --postedit=COMMAND RunCOMMAND after changes to the changelog file have been finalized, That is, after dch has been run and possible text editor has been exited, but, before changes are (possibly) committed to git. --dch-opt=dch-option Pass option to &dch; verbatim. Note that &gbp-dch; invokes &dch; multiple times and the option is passed to all invocations so not all &dch; options make sense here. Options may also conflict with options picked by &gbp-dch;. Snapshot mode can be used for quick test and install cycles without having to worry about version numbers or changelog entries. When using --snapshot or -S, &gbp-dch; uses a pseudo header in the Debian changelog to remember the last git commit it added a changelog entry for. It also sets a version number ending in ~<snaspshotnumber>.gbp<commitid>. It automatically increments the snapshot number on subsequent invocations of &gbp-dch; -S so that later snapshots automatically have a higher version number. To leave snapshot mode, invoke &gbp-dch; with the --release option. This removes the pseudo header and unmangles the version number so the released version has a higher version number than the snapshots. Additional to the above options, the formatting of the commit message in debian/changelog can be modified by special tags (called Meta Tags) given in the git commit message. Meta Tag processing can be activated via the --meta option. The tags must start at the first column of a commit message but can appear on any line. They are of the form Tagname: value. Valid Meta Tags are: Gbp-Dch: action Supported actions are: Ignore which will ignore this commit when generating debian/changelog, Short which will only use the description (the first line) of the commit message when generating the changelog entry (useful when --full is given), and Full which will use the full commit message when generating the changelog entry (useful when --full is not given). In addition to Gbp-Dch, the deprecated Git-Dch is still supported. Thanks: msg Add a thanks message after the commit message. Closes: bugnumber Indicate in the debian/changelog that the bug was closed by this commit. See the --meta-closes on how to extend this for other bugtrackers. The following git commit message: Document meta tags so one doesn't have to consult the manual Gbp-Dch: Short Closes: #636088 Thanks: Raphaël Hertzog for the suggestion Results in this debian/changelog entry: * Document meta tags.
