Jeff King	8376a70441	branch: clean up commit flags after merge-filter walk When we run `branch --merged`, we use prepare_revision_walk with the merge-filter marked as UNINTERESTING. Any branch tips that are marked UNINTERESTING after it returns must be ancestors of that commit. As we iterate through the list of refs to show, we check item->commit->object.flags to see whether it was marked. This interacts badly with --verbose, which will do a separate walk to find the ahead/behind information for each branch. There are two bad things that can happen: 1. The ahead/behind walk may get the wrong results, because it can see a bogus UNINTERESTING flag leftover from the merge-filter walk. 2. We may omit some branches if their tips are involved in the ahead/behind traversal of a branch shown earlier. The ahead/behind walk carefully cleans up its commit flags, meaning it may also erase the UNINTERESTING flag that we expect to check later. We can solve this by moving the merge-filter state for each ref into its "struct ref_item" as soon as we finish the merge-filter walk. That fixes (2). Then we are free to clear the commit flags we used in the walk, fixing (1). Note that we actually do away with the matches_merge_filter helper entirely here, and inline it between the revision walk and the flag-clearing. This ensures that nobody accidentally calls it at the wrong time (it is only safe to check in that instant between the setting and clearing of the global flag).

Jeff King	d040350813	branch: let branch filters imply --list Currently, a branch filter like `--contains`, `--merged`, or `--no-merged` is ignored when we are not in listing mode. For example: git branch --contains=foo bar will create the branch "bar" from the current HEAD, ignoring the `--contains` argument entirely. This is not very helpful. There are two reasonable behaviors for git here: 1. Flag an error; the arguments do not make sense. 2. Implicitly go into `--list` mode This patch chooses the latter, as it is more convenient, and there should not be any ambiguity with attempting to create a branch; using `--contains` and not wanting to list is nonsensical. That leaves the case where an explicit modification option like `-d` is given. We already catch the case where `--list` is given alongside `-d` and flag an error. With this patch, we will also catch the use of `--contains` and other filter options alongside `-d`.

Jeff King	82ebb0b6ec	add test_cmp function for test scripts Many scripts compare actual and expected output using "diff -u". This is nicer than "cmp" because the output shows how the two differ. However, not all versions of diff understand -u, leading to unnecessary test failure. This adds a test_cmp function to the test scripts and switches all "diff -u" invocations to use it. The function uses the contents of "$GIT_TEST_CMP" to compare its arguments; the default is "diff -u". On systems with a less-capable diff, you can do: GIT_TEST_CMP=cmp make test Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
