From 0906f6e14e6e9df0c4ea4edb08ebe9f5d16c2391 Mon Sep 17 00:00:00 2001 From: Michael Witten Date: Sun, 7 Aug 2011 02:44:43 +0000 Subject: [PATCH] filter-branch: Export variable `workdir' for --commit-filter According to `git help filter-branch': --commit-filter ... You can use the _map_ convenience function in this filter, and other convenience functions, too... ... However, it turns out that `map' hasn't been usable because it depends on the variable `workdir', which is not propogated to the environment of the shell that runs the commit-filter because the shell is created via a simple-command rather than a compound-command subshell: @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \ $(git write-tree) $parentstr < ../message > ../map/$commit || die "could not write rewritten commit" One solution is simply to export `workdir'. However, it seems rather heavy-handed to export `workdir' to the environments of all commands, so instead this commit exports `workdir' for only the duration of the shell command in question: workdir=$workdir @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \ $(git write-tree) $parentstr < ../message > ../map/$commit || die "could not write rewritten commit" Signed-off-by: Michael Witten Signed-off-by: Junio C Hamano --- git-filter-branch.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/git-filter-branch.sh b/git-filter-branch.sh index 962a93b58..6b5f2251b 100755 --- a/git-filter-branch.sh +++ b/git-filter-branch.sh @@ -363,7 +363,7 @@ while read commit parents; do sed -e '1,/^$/d' <../commit | \ eval "$filter_msg" > ../message || die "msg filter failed: $filter_msg" - @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \ + workdir=$workdir @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \ $(git write-tree) $parentstr < ../message > ../map/$commit || die "could not write rewritten commit" done <../revs -- 2.30.2
