In https://github.com/microsoft/git/issues/623, it was reported that the regularly scheduled maintenance stops if one repo in the middle of the list was found to be missing. This is undesirable, and points out a gap in the design of `git for-each-repo`: We need a mode where that command does not stop on an error, but continues to try running the specified command with the other repositories. Imitating the `--keep-going` option of GNU make, this commit teaches `for-each-repo` the same trick: to continue with the operation on all the remaining repositories in case there was a problem with one repository, still setting the exit code to indicate an error occurred.

NAME
|
|
----
|
|
git-for-each-repo - Run a Git command on a list of repositories
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git for-each-repo' --config=<config> [--] <arguments>
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Run a Git command on a list of repositories. The arguments after the
|
|
known options or `--` indicator are used as the arguments for the Git
|
|
subprocess.
|
|
|
|
THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
|
|
|
|
For example, we could run maintenance on each of a list of repositories
|
|
stored in a `maintenance.repo` config variable using
|
|
|
|
-------------
|
|
git for-each-repo --config=maintenance.repo maintenance run
|
|
-------------
|
|
|
|
This will run `git -C <repo> maintenance run` for each value `<repo>`
|
|
in the multi-valued config variable `maintenance.repo`.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
--config=<config>::
|
|
Use the given config variable as a multi-valued list storing
|
|
absolute path names. Iterate on that list of paths to run
|
|
the given arguments.
|
|
+
|
|
These config values are loaded from system, global, and local Git config,
|
|
as available. If `git for-each-repo` is run in a directory that is not a
|
|
Git repository, then only the system and global config is used.
|
|
|
|
--keep-going::
|
|
Continue with the remaining repositories if the command failed
|
|
on a repository. The exit code will still indicate that the
|
|
overall operation was not successful.
|
|
+
|
|
Note that the exact exit code of the failing command is not passed
|
|
through as the exit code of the `for-each-repo` command: If the command
|
|
failed in any of the specified repositories, the overall exit code will
|
|
be 1.
|
|
|
|
SUBPROCESS BEHAVIOR
|
|
-------------------
|
|
|
|
If any `git -C <repo> <arguments>` subprocess returns a non-zero exit code,
|
|
then the `git for-each-repo` process returns that exit code without running
|
|
more subprocesses.
|
|
|
|
Each `git -C <repo> <arguments>` subprocess inherits the standard file
|
|
descriptors `stdin`, `stdout`, and `stderr`.
