2018-07-18Merge branch 'mb/filter-branch-optim'Libravatar Junio C Hamano1-0/+15
"git filter-branch" when used with the "--state-branch" option still attempted to rewrite the commits whose filtered result is known from the previous attempt (which is recorded on the state branch); the command has been corrected not to waste cycles doing so. * mb/filter-branch-optim: filter-branch: skip commits present on --state-branch
2018-07-18Merge branch 'jk/branch-l-0-deprecation'Libravatar Junio C Hamano2-19/+19
The "-l" option in "git branch -l" is an unfortunate short-hand for "--create-reflog", but many users, both old and new, somehow expect it to be something else, perhaps "--list". This step warns when "-l" is used as a short-hand for "--create-reflog" and warns about the future repurposing of the it when it is used. * jk/branch-l-0-deprecation: branch: deprecate "-l" option t: switch "branch -l" to "branch --create-reflog" t3200: unset core.logallrefupdates when testing reflog creation

2018-06-27Fix use of strategy options with interactive rebasesLibravatar Elijah Newren1-1/+1
git-rebase.sh wrote strategy options to .git/rebase/merge/strategy_opts in the following format: '--ours' '--renormalize' Note the double spaces. git-rebase--interactive uses sequencer.c to parse that file, and sequencer.c used split_cmdline() to get the individual strategy options. After splitting, sequencer.c prefixed each "option" with a double dash, so, concatenating all its options would result in: -- --ours -- --renormalize So, when it ended up calling try_merge_strategy(), that in turn would run git merge-$strategy -- --ours -- --renormalize $merge_base -- $head $remote instead of the expected/desired git merge-$strategy --ours --renormalize $merge_base -- $head $remote Remove the extra spaces so that when it goes through split_cmdline() we end up with the desired command line.

2018-06-22t: switch "branch -l" to "branch --create-reflog"Libravatar Jeff King2-19/+19
In preparation for deprecating "-l", let's make sure we're using the recommended option ourselves. This patch just mechanically converts "branch -l" to "branch --create-reflog". Note that with the exception of the actual "--create-reflog" test, we could actually remove "-l" entirely from most of these callers. That's because these days core.logallrefupdates defaults to true in a non-bare repository. I've left them in place, though, since they serve to document the expectation of the test, even if they are technically noops.

2018-06-22t3200: unset core.logallrefupdates when testing reflog creationLibravatar Jeff King1-1/+1
This test checks that the "-l" option creates a reflog. But in fact we'd create one even without it, since the default in a non-bare repository is to do so. Let's unset the config so we can be sure our "-l" option is kicking in. Note that we can't do this with test_config, since that would leave the variable unset after our test finishes, confusing downstream tests (the helper is not not smart enough to restore the previous value, and just always runs test_unconfig).

This makes it possible to teach 'contrib/git-jump/git-jump' how to seek to the first matching position of a grep match in your editor, and allows similar additional scripting capabilities.

2018-06-19format-patch: clear UNINTERESTING flag before prepare_basesLibravatar Xiaolong Ye1-2/+4
When users specify the commit range with 'Z..C' pattern for format-patch, all the parents of Z (including Z) would be marked as UNINTERESTING which would prevent revision walk in prepare_bases from getting the prerequisite commits, thus `git format-patch --base <base_commit_sha> Z..C` won't be able to generate the list of prerequisite patch ids.

2018-06-19sequencer: do not squash 'reword' commits when we hit conflictsLibravatar Phillip Wood2-0/+76
Ever since commit 18633e1a22 ("rebase -i: use the rebase--helper builtin", 2017-02-09), when a commit marked as 'reword' in an interactive rebase has conflicts and fails to apply, when the rebase is resumed that commit will be squashed into its parent with its commit message taken. The issue can be understood better by looking at commit 56dc3ab04b ("sequencer (rebase -i): implement the 'edit' command", 2017-01-02), which introduced error_with_patch() for the edit command. For the edit command, it needs to stop the rebase whether or not the patch applies cleanly. If the patch does apply cleanly, then when it resumes it knows it needs to amend all changes into the previous commit. If it does not apply cleanly, then the changes should not be amended. Thus, it passes !res (success of applying the 'edit' commit) to error_with_patch() for the to_amend flag. The problematic line of code actually came from commit 04efc8b57c ("sequencer (rebase -i): implement the 'reword' command", 2017-01-02). Note that to get to this point in the code: * !!res (i.e. patch application failed) * item->command < TODO_SQUASH * item->command != TODO_EDIT * !is_fixup(item->command) [i.e. not squash or fixup] So that means this can only be a failed patch application that is either a pick, revert, or reword. We only need to amend HEAD when rewording the root commit or a commit that has been fast-forwarded, for any of the other cases we want a new commit, so we should not set the to_amend flag.

2018-06-18ewah_read_mmap: bounds-check mmap readsLibravatar Jeff King1-0/+13
The on-disk ewah format tells us how big the ewah data is, and we blindly read that much from the buffer without considering whether the mmap'd data is long enough, which can lead to out-of-bound reads. Let's make sure we have data available before reading it, both for the ewah header/footer as well as for the bit data itself. In particular: - keep our ptr/len pair in sync as we move through the buffer, and check it before each read - check the size for integer overflow (this should be impossible on 64-bit, as the size is given as a 32-bit count of 8-byte words, but is possible on a 32-bit system) - return the number of bytes read as an ssize_t instead of an int, again to prevent integer overflow - compute the return value using a pointer difference; this should yield the same result as the existing code, but makes it more obvious that we got our computations right The included test is far from comprehensive, as it just picks a static point at which to truncate the generated bitmap. But in practice this will hit in the middle of an ewah and make sure we're at least exercising this code.

2018-06-18t3200: clarify description of --set-upstream testLibravatar Kaartic Sivaraam1-1/+1
Support for the --set-upstream option was removed in 52668846ea (builtin/branch: stop supporting the "--set-upstream" option, 2017-08-17). The change did not completely remove the command due to an issue noted in the commit's log message. So, a test was added to ensure that a command which uses the '--set-upstream' option fails instead of silently acting as an alias for the '--set-upstream-to' option due to option parsing features. To avoid confusion, clarify that the option is disabled intentionally in the corresponding test description. The test is expected to be around as long as we intentionally fail on seeing the '--set-upstream' option which in turn we expect to do for a period of time after which we can be sure that existing users of '--set-upstream' are aware that the option is no longer supported.

2018-06-15tests: clean after SANITY testsLibravatar Junio C Hamano5-9/+6
Some of our tests try to make sure Git behaves sensibly in a read-only directory, by dropping 'w' permission bit before doing a test and then restoring it after it is done. The latter is needed for the test framework to clean after itself without leaving a leftover directory that cannot be removed. Ancient parts of tests however arrange the above with chmod a-w . && ... do the test ... status=$? chmod 775 . (exit $status) which obviously would not work if the test somehow dies before it has the chance to do "chmod 775". Rewrite them by following a more robust pattern recently written tests use, which is test_when_finished "chmod 775 ." && chmod a-w . && ... do the test ...

2018-06-14submodule: unset core.worktree if no working tree is presentLibravatar Stefan Beller1-1/+2
When a submodules work tree is removed, we should unset its core.worktree setting as the worktree is no longer present. This is not just in line with the conceptual view of submodules, but it fixes an inconvenience for looking at submodules that are not checked out: git clone --recurse-submodules git://github.com/git/git && cd git && git checkout --recurse-submodules v2.13.0 git -C .git/modules/sha1collisiondetection log fatal: cannot chdir to '../../../sha1collisiondetection': \ No such file or directory With this patch applied, the final call to git log works instead of dying in its setup, as the checkout will unset the core.worktree setting such that following log will be run in a bare repository. This patch covers all commands that are in the unpack machinery, i.e. checkout, read-tree, reset. A follow up patch will address "git submodule deinit", which will also make use of the new function submodule_unset_core_worktree(), which is why we expose it in this patch.
