I am using git reflog to get information about branches, as i need to know the name of the branch passed to the command.
for example when using git rebase --onto master, I need to know that master branch is used for rebasing. the problem is that reflog does not say which branch was used. Instead it shows the SHA of the commit that this branch was rebased onto.
check the following ref-log output (the branch was rebased onto master)
7f3a5b9 rebase-test/rebase-2@{1}: rebase finished: refs/heads/rebase-test/rebase-2 onto a9d523f1a73fe2cd2857ee3d013463069fe51c3d
5161e07 rebase-test/rebase-2@{2}: commit: adding rebase-file4
c8d0ed0 rebase-test/rebase-2@{3}: commit: adding rebase-file3
6ab1277 rebase-test/rebase-2@{4}: branch: Created from rebase-test/rebase-1
now I need to know which branch this commit SHA a9d523f1a73fe2cd2857ee3d013463069fe51c3d belonged to at the time of rebase. This should work even if master has moved on since that time.
I tried git log with multiple options but it returns the current state of the branches not at specific time.
How can I get this information? If not possible to get the exact reference (master in this case), perhaps it is possible to get all references of this commit at that time?
EDIT
base on @Jubobs commit, may be i can rephrase the question to: Which references were associated with this commit at the time of rebase
