Junio C Hamano	1fe32cb9d0	filter-branch: handle filenames that need quoting The command used a very old fashioned construct to extract filenames out of diff-index and ended up corrupting the output. We can simply use --name-only and pipe into --stdin mode of update-index. It's been like that for the past 2 years or so since `a94d994` (update-index: work with c-quoted name).

Johannes Sixt	fdd7d48d6a	t7003-filter-branch: Fix test of a failing --msg-filter. The test passed for the wrong reason: If the script given to --msg-filter fails, it is expected that git-filter-branch aborts. But the test forgot to tell the branch name to rewrite, and so git-filter-branch failed due to incorrect usage.

Johannes Schindelin	46eb449cbe	filter-branch: update current branch when rewritten Earlier, "git filter-branch --<options> HEAD" would not update the working tree after rewriting the branch. This commit fixes it. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>	17 years ago
Johannes Schindelin	f95eef15f2	filter-branch: introduce convenience function "skip_commit" With this function, a commit filter can leave out unwanted commits (such as temporary commits). It does _not_ undo the changeset corresponding to that commit, but it _skips_ the revision. IOW no tree object is changed by this. If you like to commit early and often, but want to filter out all intermediate commits, marked by "@@@" in the commit message, you can now do this with git filter-branch --commit-filter ' if git cat-file commit $GIT_COMMIT \| grep '@@@' > /dev/null; then skip_commit "$@"; else git commit-tree "$@"; fi' newbranch Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Johannes Schindelin	7e0f1704b8	filter-branch: provide the convenience functions also for commit filters Move the convenience functions to the top of git-filter-branch.sh, and return from the script when the environment variable SOURCE_FUNCTIONS is set. By sourcing git-filter-branch with that variable set automatically, all commit filters may access the convenience functions like "map".

Johannes Schindelin	dfd05e38f0	filter-branch: Big syntax change; support rewriting multiple refs We used to take the first non-option argument as the name for the new branch. This syntax is not extensible to support rewriting more than just HEAD. Instead, we now have the following syntax: git filter-branch [<filter options>...] [<rev-list options>] All positive refs given in <rev-list options> are rewritten. Yes, in-place. If a ref was changed, the original head is stored in refs/original/$ref now, for your inspecting pleasure, in addition to the reflogs (since it is easier to inspect "git show-ref \| grep original" than to inspect all the reflogs). This commit also adds the --force option to remove .git-rewrite/ and all refs from refs/original/ before filtering.

Johannes Schindelin	8c1ce0f46b	filter-branch: fail gracefully when a filter fails A common mistake is to provide a filter which fails unwantedly. For example, this will stop in the middle: git filter-branch --env-filter ' test $GIT_COMMITTER_EMAIL = xyz && export GIT_COMMITTER_EMAIL = abc' rewritten When $GIT_COMMITTER_EMAIL is not "xyz", the test fails, and consequently the whole filter has a non-zero exit status. However, as demonstrated in this example, filter-branch would just stop, and the user would be none the wiser. Also, a failing msg-filter would not have been caught, as was the case with one of the tests. This patch fixes both issues, by paying attention to the exit status of msg-filter, and by saying what failed before exiting.

Johannes Schindelin	f6b78c6eb6	filter-branch: add a test for the commit removal example In the man page, there is an example which describes how to remove single commits (although it keeps the changes which were not reverted in the next non-removed commit). Better make sure that it works as expected. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>	18 years ago

Johannes Sixt	cfabd6eee1	filter-branch: subdirectory filter needs --full-history When two branches are merged that modify a subdirectory (possibly in different intermediate steps) such that both end up identical, then rev-list chooses only one branch. But when we filter history, we want to keep both branches. Therefore, we must use --full-history.

Johannes Schindelin	685ef546b6	Teach filter-branch about subdirectory filtering With git-filter-branch --subdirectory-filter <subdirectory> you can get at the history, as seen by a certain subdirectory. The history of the rewritten branch will only contain commits that touched that subdirectory, and the subdirectory will be rewritten to be the new project root.

Johannes Sixt	2766ce2815	filter-branch: Use rev-list arguments to specify revision ranges. A subset of commits in a branch used to be specified by options (-k, -r) as well as the branch tip itself (-s). It is more natural (for git users) to specify revision ranges like 'master..next' instead. This makes it so. If no range is specified it defaults to 'HEAD'. As a consequence, the new name of the filtered branch must be the first non-option argument. All remaining arguments are passed to 'git rev-list' unmodified. The tip of the branch that gets filtered is implied: It is the first commit that git rev-list would print for the specified range.

Johannes Schindelin	9840906026	filter-branch: fix behaviour of '-k' The option '-k' says that the given commit and _all_ of its ancestors are kept as-is. However, if a to-be-rewritten commit branched from an ancestor of an ancestor of a commit given with '-k', filter-branch would fail. Example: A - B \ C If filter-branch was called with '-k B -s C', it would actually keep B (and A as its parent), but would rewrite C, and its parent. Noticed by Johannes Sixt.

Johannes Schindelin	6f6826c52b	Add git-filter-branch This script is derived from Pasky's cg-admin-rewritehist. In fact, it _is_ the same script, minimally adapted to work without cogito. It _should_ be able to perform the same tasks, even if only relying on core-git programs. All the work is Pasky's, just the adaption is mine.
