How to find pull-request by a commit sha
Lets have a commit E which is in some unknown pull-request.
--ancestry-path option can be used to list all commits between master and E
git log --ancestry-path master ^E
for:
A last commit in master
B Merge pull request #2258 ...
|\
C | some comiit in master
| D onther commit in searched pull-request
| E given commit
it returns:
A last commit in master
B Merge pull request #2258 ...
D onther commit in searched pull-request
If last merge commit from the list is taken we get the merge commit for E with searched pull-request number.
To do that we use options:
git log --reverse --grep=\"Merge pull request\" -n 1 --ancestry-path master ^E
which returns only B Merge pull request #2258 the merge commit with searched pull-request number.
Git Alias
For convenience it can be turned into git alias.
logpr = !sh -c 'git log --reverse --grep=\"Merge pull request\" -n 1 \
--ancestry-path master ^$1 $@' -
Then
$ git logpr 4b6d8f9 --oneline
d2a35bc Merge pull request #2258 from daviddavis/temp_1368456830
Caution
This works only if all pull-requests are merged directly into master.
