Git create patch series

Vitaly: is your patch readable if you open it with a text editor? Otherwise, it looks like an encoding problem. I think it easier to remember. I am new to git and wondered why I got an empty patch everytime — Anonymous. Show 8 more comments. Sometimes it might be useful to create a patch relative to the current directory. To achieve this, use git diff --relative — ejboy. Terse bordering on sarcastic, the answer below is more helpful. Select the Mixed option.

Technically this does require creating a commit which OP asked to avoid, but it's a temporary one and the answer is useful regardless. Ionel Sirbu Ionel Sirbu 4 4 silver badges 3 3 bronze badges. Are they compatible with each other? RakshithRavi afaik, yes they are. UPD For those who did not get the idea of format-patch Add alias: git config --global alias. Patch will contain all the changes and untracked files that are visible to next command: git status.

Eugen Konkov Eugen Konkov There is a simpler way than creating a commit and uncommiting. IgorGanapolsky: Do you notice alias? This site uses Akismet to reduce spam.

Fortunately git could export those commits into patches with this command: git format-patch -x where -x means how many commits back from the current head and it has to be integer.

For example if i want to generate patch for 10 last commits : git format-patch The above example will generate 10 file patches, this will cause a problem for the team leader, because he need to apply the patches one by one. Note: The generated patches also work with subversion svn. Categories: Git Tagged With: git patches , git scm.

Do not output contents of changes in binary files, instead display a notice that those files changed. Patches generated using this option cannot be applied properly, but they are still useful for code review.

Record the base tree information to identify the state the patch series applies to. The --no-base option overrides a format. Note that root commits included in the specified range are always formatted as creation patches, independently of this flag.

You can specify extra mail header lines to be added to each message, defaults for the subject prefix and file suffix, number patches when outputting more than one patch, add "To:" or "Cc:" headers, configure attachments, change the patch output directory, and sign off patches with configuration variables. The patch produced by git format-patch is in UNIX mailbox format, with a fixed "magic" time stamp to indicate that the file is output from format-patch rather than a real mailbox, like so:.

On the receiving end, readers can save interesting patches in a UNIX mailbox and apply them with git-am[1]. When a patch is part of an ongoing discussion, the patch generated by git format-patch can be tweaked to take advantage of the git am --scissors feature.

The patch title is likely to be different from the subject of the discussion the patch is in response to, so it is likely that you would want to keep the Subject: line, like the example above. Many mailers if not set up properly will corrupt whitespace. Here are two common types of corruption:.

Send the patch to yourself, exactly the way you would, except with To: and Cc: lines that do not contain the list and maintainer address. The patch itself does not apply cleanly. That is bad but does not have much to do with your MUA. You might want to rebase the patch with git-rebase[1] before regenerating it in this case. The MUA corrupted your patch; "am" would complain that the patch does not apply. Look in the.

While at it, check the info and final-commit files as well. If what is in final-commit is not exactly what you would want to see in the commit log message, it is very likely that the receiver would end up hand editing the log message when applying your patch. Things like "Hi, this is my first patch. GMail does not have any way to turn off line wrapping in the web interface, so it will mangle any emails that you send. There are three different approaches: use an add-on to turn off line wraps, configure Thunderbird to not mangle patches, or use an external editor to keep Thunderbird from mangling the patches.

In Thunderbird 3: Edit.. Config Editor. Search for "mail. Toggle it to make sure it is set to false. Also, search for "mailnews. Search for "mailnews. To use it, do the steps above and then use the script as the external editor. Back in the compose window: add whatever other text you wish to the message, complete the addressing and subject fields, and press send.

The base tree information block is used for maintainers or third party testers to know the exact state the patch series applies to. It consists of the base commit , which is a well-known commit that is part of the stable part of the project history everybody else works off of, and zero or more prerequisite patches , which are well-known patches in flight that is not yet part of the base commit that need to be applied on top of base commit in topological order before the patches can be applied.

The base commit is shown as "base-commit: " followed by the hex of the commit object name. A prerequisite patch is shown as "prerequisite-patch-id: " followed by the hex patch id , which can be obtained by passing the patch through the git patch-id --stable command.

Imagine that on top of the public commit P, you applied well-known patches X, Y and Z from somebody else, and then built your three-patch series A, B, C, the history would be like:. C instead of -3 C to specify the range , the base tree information block is shown at the end of the first message the command outputs either the first patch, or the cover letter , like this:. For a local branch, you need to make it to track a remote branch by git branch --set-upstream-to before using this option.

Extract commits between revisions R1 and R2, and apply them on top of the current branch using git am to cherry-pick them:. Additionally, it detects and handles renames and complete rewrites intelligently to produce a renaming patch.

A renaming patch reduces the amount of text output, and generally makes it easier to review. Note that format-patch will omit merge commits from the output, even if they are part of the requested range. A simple "patch" does not include enough information for the receiving end to reproduce the same merge commit.

NAME git-format-patch - Prepare patches for e-mail submission. The second and subsequent paragraphs of the commit log message.

The log message and the patch is separated by a line with a three-dash line. Currently, this is the default. Blank lines are ignored, so they can be used as separators for readability. Each other line contains a single pattern.
