Preparing, checking and sending patches to a mailing list is a tedious and
error-prone process. Dealing with multiple series, each which its own
revision history, CC list, cover letter requires concentation. Mistakes
are easy to make.
This tool aims to help with this. A single command generates the patch
series, runs it through checkpatch, generates the cover letter, adds a
change list to each patch and the cover letter, determines who should
receive the patch and Ccs people on the patch either using maintainer
information or tags in the commit subject. A dry-run mode allows output
to be checked.
This tool makes patch series repeatable, since everything needed to create
and send patches in stored in the git branch containing that series.
When making a change to one commit you can update the change log in that
commit and know that everything will turn out OK.
Specifically this tool is a Python script which (from the README):
- Creates patch directly from your branch
- Cleans them up by removing unwanted tags
- Inserts a cover letter with change lists
- Runs the patches through checkpatch.pl and its own checks
- Optionally emails them out to selected people
It is intended to automate patch creation and make it a less
error-prone process. It is useful for U-Boot and Linux work so far,
since it uses the checkpatch.pl script.
It is configured almost entirely by tags it finds in your commits.
This means that you can work on a number of different branches at
once, and keep the settings with each branch rather than having to
git format-patch, git send-email, etc. with the correct parameters
each time. So for example if you put:
Series-to: [email protected]
in one of your commits, the series will be sent there.
In Linux and U-Boot this will also call get_maintainer.pl on each of your
patches automatically (unless you use -m to disable this).
I am submitting this to LKML to raise awareness, since those who are not
involved in U-Boot probably don't know about it. I could not find a
specific linux-tools list but may have missed something.

+What is this?
+=============
+
+This tool is a Python script which:
+- Creates patch directly from your branch
+- Cleans them up by removing unwanted tags
+- Inserts a cover letter with change lists
+- Runs the patches through checkpatch.pl and its own checks
+- Optionally emails them out to selected people
+
+It is intended to automate patch creation and make it a less
+error-prone process. It is useful for U-Boot and Linux work so far,
+since it uses the checkpatch.pl script.
+
+It is configured almost entirely by tags it finds in your commits.
+This means that you can work on a number of different branches at
+once, and keep the settings with each branch rather than having to
+git format-patch, git send-email, etc. with the correct parameters
+each time. So for example if you put:
+
+Series-to: [email protected]
+
+in one of your commits, the series will be sent there.
+
+In Linux and U-Boot this will also call get_maintainer.pl on each of your
+patches automatically (unless you use -m to disable this).
+
+
+How to use this tool
+====================
+
+This tool requires a certain way of working:
+
+- Maintain a number of branches, one for each patch series you are
+working on
+- Add tags into the commits within each branch to indicate where the
+series should be sent, cover letter, version, etc. Most of these are
+normally in the top commit so it is easy to change them with 'git
+commit --amend'
+- Each branch tracks the upstream branch, so that this script can
+automatically determine the number of commits in it (optional)
+- Check out a branch, and run this script to create and send out your
+patches. Weeks later, change the patches and repeat, knowing that you
+will get a consistent result each time.
+
+
+How to configure it
+===================
+
+For most cases of using patman for U-Boot development, patman can use the
+file 'doc/git-mailrc' in your U-Boot directory to supply the email aliases
+you need. To make this work, tell git where to find the file by typing
+this once:
+
+ git config sendemail.aliasesfile doc/git-mailrc
+
+For both Linux and U-Boot the 'scripts/get_maintainer.pl' handles figuring
+out where to send patches pretty well.
+
+During the first run patman creates a config file for you by taking the default
+user name and email address from the global .gitconfig file.
+
+To add your own, create a file ~/.patman like this:
+
+>>>>
+# patman alias file
+
+[alias]
+me: Simon Glass <[email protected]>
+
+u-boot: U-Boot Mailing List <[email protected]>
+wolfgang: Wolfgang Denk <[email protected]>
+others: Mike Frysinger <[email protected]>, Fred Bloggs <[email protected]>
+
+<<<<
+
+Aliases are recursive.
+
+The checkpatch.pl in the U-Boot tools/ subdirectory will be located and
+used. Failing that you can put it into your path or ~/bin/checkpatch.pl
+
+
+If you want to change the defaults for patman's command-line arguments,
+you can add a [settings] section to your .patman file. This can be used
+for any command line option by referring to the "dest" for the option in
+patman.py. For reference, the useful ones (at the moment) shown below
+(all with the non-default setting):
+
+>>>
+
+[settings]
+ignore_errors: True
+process_tags: False
+verbose: True
+
+<<<
+
+
+If you want to adjust settings (or aliases) that affect just a single
+project you can add a section that looks like [project_settings] or
+[project_alias]. If you want to use tags for your linux work, you could
+do:
+
+>>>
+
+[linux_settings]
+process_tags: True
+
+<<<
+
+
+How to run it
+=============
+
+First do a dry run:
+
+$ ./tools/patman/patman -n
+
+If it can't detect the upstream branch, try telling it how many patches
+there are in your series:
+
+$ ./tools/patman/patman -n -c5
+
+This will create patch files in your current directory and tell you who
+it is thinking of sending them to. Take a look at the patch files.
+
+$ ./tools/patman/patman -n -c5 -s1
+
+Similar to the above, but skip the first commit and take the next 5. This
+is useful if your top commit is for setting up testing.
+
+
+How to add tags
+===============
+
+To make this script useful you must add tags like the following into any
+commit. Most can only appear once in the whole series.
+
+Series-to: email / alias
+ Email address / alias to send patch series to (you can add this
+ multiple times)
+
+Series-cc: email / alias, ...
+ Email address / alias to Cc patch series to (you can add this
+ multiple times)
+
+Series-version: n
+ Sets the version number of this patch series
+
+Series-prefix: prefix
+ Sets the subject prefix. Normally empty but it can be RFC for
+ RFC patches, or RESEND if you are being ignored. The patch subject
+ is like [RFC PATCH] or [RESEND PATCH].
+ In the meantime, git format.subjectprefix option will be added as
+ well. If your format.subjectprefix is set to InternalProject, then
+ the patch shows like: [InternalProject][RFC/RESEND PATCH]
+
+Series-name: name
+ Sets the name of the series. You don't need to have a name, and
+ patman does not yet use it, but it is convenient to put the branch
+ name here to help you keep track of multiple upstreaming efforts.
+
+Cover-letter:
+This is the patch set title
+blah blah
+more blah blah
+END
+ Sets the cover letter contents for the series. The first line
+ will become the subject of the cover letter
+
+Cover-letter-cc: email / alias
+ Additional email addresses / aliases to send cover letter to (you
+ can add this multiple times)
+
+Series-notes:
+blah blah
+blah blah
+more blah blah
+END
+ Sets some notes for the patch series, which you don't want in
+ the commit messages, but do want to send, The notes are joined
+ together and put after the cover letter. Can appear multiple
+ times.
+
+Commit-notes:
+blah blah
+blah blah
+more blah blah
+END
+ Similar, but for a single commit (patch). These notes will appear
+ immediately below the --- cut in the patch file.
+
+ Signed-off-by: Their Name <email>
+ A sign-off is added automatically to your patches (this is
+ probably a bug). If you put this tag in your patches, it will
+ override the default signoff that patman automatically adds.
+ Multiple duplicate signoffs will be removed.
+
+ Tested-by: Their Name <email>
+ Reviewed-by: Their Name <email>
+ Acked-by: Their Name <email>
+ These indicate that someone has tested/reviewed/acked your patch.
+ When you get this reply on the mailing list, you can add this
+ tag to the relevant commit and the script will include it when
+ you send out the next version. If 'Tested-by:' is set to
+ yourself, it will be removed. No one will believe you.
+
+Series-changes: n
+- Guinea pig moved into its cage
+- Other changes ending with a blank line
+<blank line>
+ This can appear in any commit. It lists the changes for a
+ particular version n of that commit. The change list is
+ created based on this information. Each commit gets its own
+ change list and also the whole thing is repeated in the cover
+ letter (where duplicate change lines are merged).
+
+ By adding your change lists into your commits it is easier to
+ keep track of what happened. When you amend a commit, remember
+ to update the log there and then, knowing that the script will
+ do the rest.
+
+Patch-cc: Their Name <email>
+ This copies a single patch to another email address. Note that the
+ Cc: used by git send-email is ignored by patman, but will be
+ interpreted by git send-email if you use it.
+
+Series-process-log: sort, uniq
+ This tells patman to sort and/or uniq the change logs. It is
+ assumed that each change log entry is only a single line long.
+ Use 'sort' to sort the entries, and 'uniq' to include only
+ unique entries. If omitted, no change log processing is done.
+ Separate each tag with a comma.
+
+Various other tags are silently removed, like these Chrome OS and
+Gerrit tags:
+
+BUG=...
+TEST=...
+Change-Id:
+Review URL:
+Reviewed-on:
+Commit-xxxx: (except Commit-notes)
+
+Exercise for the reader: Try adding some tags to one of your current
+patch series and see how the patches turn out.
+
+
+Where Patches Are Sent
+======================
+
+Once the patches are created, patman sends them using git send-email. The
+whole series is sent to the recipients in Series-to: and Series-cc.
+You can Cc individual patches to other people with the Patch-cc: tag. Tags
+in the subject are also picked up to Cc patches. For example, a commit like
+this:
+
+>>>>
+commit 10212537b85ff9b6e09c82045127522c0f0db981
+Author: Mike Frysinger <[email protected]>
+Date: Mon Nov 7 23:18:44 2011 -0500
+
+ x86: arm: add a git mailrc file for maintainers
+
+ This should make sending out e-mails to the right people easier.
+
+ Patch-cc: sandbox, mikef, ag
+ Patch-cc: afleming
+<<<<
+
+will create a patch which is copied to x86, arm, sandbox, mikef, ag and
+afleming.
+
+If you have a cover letter it will get sent to the union of the Patch-cc
+lists of all of the other patches. If you want to sent it to additional
+people you can add a tag:
+
+Cover-letter-cc: <list of addresses>
+
+These people will get the cover letter even if they are not on the To/Cc
+list for any of the patches.
+
+
+Example Work Flow
+=================
+
+The basic workflow is to create your commits, add some tags to the top
+commit, and type 'patman' to check and send them.
+
+Here is an example workflow for a series of 4 patches. Let's say you have
+these rather contrived patches in the following order in branch us-cmd in
+your tree where 'us' means your upstreaming activity (newest to oldest as
+output by git log --oneline):
+
+ 7c7909c wip
+ 89234f5 Don't include standard parser if hush is used
+ 8d640a7 mmc: sparc: Stop using builtin_run_command()
+ 0c859a9 Rename run_command2() to run_command()
+ a74443f sandbox: Rename run_command() to builtin_run_command()
+
+The first patch is some test things that enable your code to be compiled,
+but that you don't want to submit because there is an existing patch for it
+on the list. So you can tell patman to create and check some patches
+(skipping the first patch) with:
+
+ patman -s1 -n
+
+If you want to do all of them including the work-in-progress one, then
+(if you are tracking an upstream branch):
+
+ patman -n
+
+Let's say that patman reports an error in the second patch. Then:
+
+ git rebase -i HEAD~6
+ <change 'pick' to 'edit' in 89234f5>
+ <use editor to make code changes>
+ git add -u
+ git rebase --continue
+
+Now you have an updated patch series. To check it:
+
+ patman -s1 -n
+
+Let's say it is now clean and you want to send it. Now you need to set up
+the destination. So amend the top commit with:
+
+ git commit --amend
+
+Use your editor to add some tags, so that the whole commit message is:
+
+ The current run_command() is really only one of the options, with
+ hush providing the other. It really shouldn't be called directly
+ in case the hush parser is bring used, so rename this function to
+ better explain its purpose.
+
+ Series-to: u-boot
+ Series-cc: bfin, marex
+ Series-prefix: RFC
+ Cover-letter:
+ Unified command execution in one place
+
+ At present two parsers have similar code to execute commands. Also
+ cmd_usage() is called all over the place. This series adds a single
+ function which processes commands called cmd_process().
+ END
+
+ Change-Id: Ica71a14c1f0ecb5650f771a32fecb8d2eb9d8a17
+
+
+You want this to be an RFC and Cc the whole series to the bfin alias and
+to Marek. Two of the patches have tags (those are the bits at the front of
+the subject that say mmc: sparc: and sandbox:), so 8d640a7 will be Cc'd to
+mmc and sparc, and the last one to sandbox.
+
+Now to send the patches, take off the -n flag:
+
+ patman -s1
+
+The patches will be created, shown in your editor, and then sent along with
+the cover letter. Note that patman's tags are automatically removed so that
+people on the list don't see your secret info.
+
+Of course patches often attract comments and you need to make some updates.
+Let's say one person sent comments and you get an Acked-by: on one patch.
+Also, the patch on the list that you were waiting for has been merged,
+so you can drop your wip commit. So you resync with upstream:
+
+ git fetch origin (or whatever upstream is called)
+ git rebase origin/master
+
+and use git rebase -i to edit the commits, dropping the wip one. You add
+the ack tag to one commit:
+
+ Acked-by: Heiko Schocher <[email protected]>
+
+update the Series-cc: in the top commit:
+
+ Series-cc: bfin, marex, Heiko Schocher <[email protected]>
+
+and remove the Series-prefix: tag since it it isn't an RFC any more. The
+series is now version two, so the series info in the top commit looks like
+this:
+
+ Series-to: u-boot
+ Series-cc: bfin, marex, Heiko Schocher <[email protected]>
+ Series-version: 2
+ Cover-letter:
+ ...
+
+Finally, you need to add a change log to the two commits you changed. You
+add change logs to each individual commit where the changes happened, like
+this:
+

+(note the blank line at the end of the list)
+
+When you run patman it will collect all the change logs from the different
+commits and combine them into the cover letter, if you have one. So finally
+you have a new series of commits:
+
+ faeb973 Don't include standard parser if hush is used
+ 1b2f2fe mmc: sparc: Stop using builtin_run_command()
+ cfbe330 Rename run_command2() to run_command()
+ 0682677 sandbox: Rename run_command() to builtin_run_command()
+
+so to send them:
+
+ patman
+
+and it will create and send the version 2 series.
+
+General points:
+
+1. When you change back to the us-cmd branch days or weeks later all your
+information is still there, safely stored in the commits. You don't need
+to remember what version you are up to, who you sent the last lot of patches
+to, or anything about the change logs.
+
+2. If you put tags in the subject, patman will Cc the maintainers
+automatically in many cases.
+
+3. If you want to keep the commits from each series you sent so that you can
+compare change and see what you did, you can either create a new branch for
+each version, or just tag the branch before you start changing it:
+
+ git tag sent/us-cmd-rfc
+ ...later...
+ git tag sent/us-cmd-v2
+
+4. If you want to modify the patches a little before sending, you can do
+this in your editor, but be careful!
+
+5. If you want to run git send-email yourself, use the -n flag which will
+print out the command line patman would have used.
+
+6. It is a good idea to add the change log info as you change the commit,
+not later when you can't remember which patch you changed. You can always
+go back and change or remove logs from commits.
+
+
+Other thoughts
+==============
+
+This script has been split into sensible files but still needs work.
+Most of these are indicated by a TODO in the code.
+
+It would be nice if this could handle the In-reply-to side of things.
+
+The tests are incomplete, as is customary. Use the --test flag to run them,
+and make sure you are in the tools/patman directory first:
+
+ $ cd /path/to/u-boot
+ $ cd tools/patman
+ $ ./patman --test
+
+Error handling doesn't always produce friendly error messages - e.g.
+putting an incorrect tag in a commit may provide a confusing message.
+
+There might be a few other features not mentioned in this README. They
+might be bugs. In particular, tags are case sensitive which is probably
+a bad thing.

Don't get me wrong but is this really worth 3000+ lines of python?
The tasks you describe can be done using a few lines bash.

#!/bin/bash
patman $@
I obviously failed in my attempt to briefly explain what it does.
Please check out the cover letter [1], README [2], or perhaps use it
on a series. With respect to the length, it could be slimmed down a
bit if that is important.

the README file did the trick. ;)
Sounds like a useful tool to manage patch series.
But I don't think it makes much sense to carry it with the Linux kernel tree.
Other projects can also use it and it does not seem to be very Linux kernel
specific.
git, quilt and other great tools also have their own repositories.

My reasoning is that:
- more will find it / use it if it is in-tree
- it avoids installation and old-version problems (e.g. I suppose this
is why the device tree compiler is built-in)
- it is somewhat Linux-specific (e.g. uses get_maintainers,
checkpatch.pl) and can break if checkpatch.pl if the wrong version
(e.g. you check out and send patches from an older tree)
- it could be built into the Linux workflow [1] and might thereby
reduce the amount of confusion and errors (did you run checkpatch?,
your change log is in the wrong place, you forgot to add your
sign-off, etc.)
That said, I could see this having a repo of its own, with the Linux
version a downstream copy, a bit like dtc (and maybe Kbuild/Kconfig -
I don't know). The feature set is probably mature enough to support
that now.

If we'd follow these arguments we'd have to move the whole GNU into the
kernel tree. ;-)
checkpatch.pl and get_maintainers.pl are not really a show-stopper.
Other projects are using them too. You can make them also configurable.
i.e. check_script and get_maintaner_script.

Well maybe the first two.

Understood, I'm just explaining my reasoning for sending this patch.
With U-Boot it has been very convenient to be able to rely on this
being available in the tree. 3000 lines is a drop in the ocean with
Linux's 22m lines.
But I fully understand your point of view. If nothing else, at least
this series provides an easy way for people to try it out.
