# An example hook script to validate a patch (and/or patch series) before
|
||
|
|
# sending it via email.
|
||
|
|
#
|
||
|
|
# The hook should exit with non-zero status after issuing an appropriate
|
||
|
|
# message if it wants to prevent the email(s) from being sent.
|
||
|
|
#
|
||
|
|
# To enable this hook, rename this file to "sendemail-validate".
|
||
|
|
#
|
||
|
|
# By default, it will only check that the patch(es) can be applied on top of
|
||
|
|
# the default upstream branch without conflicts in a secondary worktree. After
|
||
|
|
# validation (successful or not) of the last patch of a series, the worktree
|
||
|
|
# will be deleted.

||
|

|
||
|
|
# remote ref that are used to apply the patches against:
|

#
|

|
|
# sendemail.validateRemote (default: origin)
|
||
|
|
# sendemail.validateRemoteRef (default: HEAD)

# Replace the TODO placeholders with appropriate checks according to your

|
|
# needs.
