2024-11-21t: remove TEST_PASSES_SANITIZE_LEAK annotationsPatrick Steinhardt1-1/+0
Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there is no longer a need to have that variable declared in all of our tests. Drop it. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-11-16rebase: fully ignore rebase.autoSquash without -iAndy Koppe1-12/+0
Setting the rebase.autoSquash config variable to true implies a couple of restrictions: it prevents preemptive fast-forwarding and it triggers conflicts with apply backend options. However, it only actually results in auto-squashing when combined with the --interactive (or -i) option, due to code in run_specific_rebase() that disables auto-squashing unless the REBASE_INTERACTIVE_EXPLICIT flag is set. Doing autosquashing for rebase.autoSquash without --interactive would be problematic in terms of backward compatibility, but conversely, there is no need for the aforementioned restrictions without --interactive. So drop the options.config_autosquash check from the conditions for clearing allow_preemptive_ff, as the case where it is combined with --interactive is already covered by the REBASE_INTERACTIVE_EXPLICIT flag check above it. Also drop the "apply options are incompatible with rebase.autoSquash" error, because it is unreachable if it is restricted to --interactive, as apply options already cause an error when used with --interactive. Drop the tests for the error from t3422-rebase-incompatible-options.sh, which has separate tests for the conflicts of --interactive with apply options. When neither --autosquash nor --no-autosquash are given, only set options.autosquash to true if rebase.autosquash is combined with --interactive. Don't initialize options.config_autosquash to -1, as there is no need to distinguish between rebase.autoSquash being unset or explicitly set to false. Finally, amend the rebase.autoSquash documentation to say it only affects interactive mode. Signed-off-by: Andy Koppe <andy.koppe@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-03-27rebase: add a config option for --rebase-mergesAlex Henrie1-0/+17
The purpose of the new option is to accommodate users who would like --rebase-merges to be on by default and to facilitate turning on --rebase-merges by default without configuration in a future version of Git. Name the new option rebase.rebaseMerges, even though it is a little redundant, for consistency with the name of the command line option and to be clear when scrolling through values in the [rebase] section of .gitconfig. Support setting rebase.rebaseMerges to the nonspecific value "true" for users who don't need to or don't want to learn about the difference between rebase-cousins and no-rebase-cousins. Make --rebase-merges without an argument on the command line override any value of rebase.rebaseMerges in the configuration, for consistency with other command line flags with optional arguments that have an associated config option.

2023-01-25rebase: provide better error message for apply options vs. merge configElijah Newren1-0/+24
When config which selects the merge backend (currently, rebase.autosquash=true or rebase.updateRefs=true) conflicts with other options on the command line (such as --whitespace=fix), make the error message specifically call out the config option and specify how to override that config option on the command line.

2023-01-25rebase: add coverage of other incompatible optionsElijah Newren1-0/+15
The git-rebase manual noted several sets of incompatible options, but we were missing tests for a few of these. Further, we were missing code checks for one of these, which could result in command line options being silently ignored. Also, note that adding a check for autosquash means that using --whitespace=fix together with the config setting rebase.autosquash=true will trigger an error. A subsequent commit will improve the error message. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-01-25rebase: fix incompatiblity checks for --[no-]reapply-cherry-picksElijah Newren1-0/+10
--[no-]reapply-cherry-picks was traditionally only supported by the sequencer. Support was added for the apply backend, when --keep-base is also specified, in commit ce5238a690 ("rebase --keep-base: imply --reapply-cherry-picks", 2022-10-17). Make the code error out when --[no-]reapply-cherry-picks is specified AND the apply backend is used AND --keep-base is not specified. Also, clarify a number of comments surrounding the interaction of these flags.

2023-01-25rebase: fix docs about incompatibilities with --rootElijah Newren1-0/+4
In commit 5dacd4abdd ("git-rebase.txt: document incompatible options", 2018-06-25), I added notes about incompatibilities between options for the apply and merge backends. Unfortunately, I inverted the condition when --root was incompatible with the apply backend. Fix the documentation, and add a testcase that verifies the documentation matches the code. While at it, the documentation for --root also tried to cover some of the backend differences between the apply and merge backends in relation to reapplying cherry picks. The information: * assumed that the apply backend was the default (it isn't anymore) * was written before --reapply-cherry-picks became an option * was written before the detailed information on backend differences All of these factors make the sentence under --root about reapplying cherry picks contradict information that is now available elsewhere in the manual, and the other references are correct. So just strike this sentence. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-01-25rebase: flag --apply and --merge as incompatibleElijah Newren1-0/+3
Previously, we flagged options which implied --apply as being incompatible with options which implied --merge. But if both options were given explicitly, then we didn't flag the incompatibility. The same is true with --apply and --interactive. Add the check, and add some testcases to verify these are also caught.

2023-01-25rebase: mark --update-refs as requiring the merge backendElijah Newren1-5/+10
--update-refs is built in terms of the sequencer, which requires the merge backend. It was already marked as incompatible with the apply backend in the git-rebase manual, but the code didn't check for this incompatibility and warn the user. Check and error now. While at it, fix a typo in t3422...and fix some misleading wording (most options which used to be am-specific have since been implemented in the merge backend as well).

2021-11-18checkout: fix "branch info" memory leaksÆvar Arnfjörð Bjarmason1-0/+2
The "checkout" command is one of the main sources of leaks in the test suite, let's fix the common ones by not leaking from the "struct branch_info". Doing this is rather straightforward, albeit verbose, we need to xstrdup() constant strings going into the struct, and free() the ones we clobber as we go along. This also means that we can delete previous partial leak fixes in this area, i.e. the "path_to_free" accounting added by 96ec7b1e708 (Convert resolve_ref+xstrdup to new resolve_refdup function, 2011-12-13). There was some discussion about whether "we should retain the "const char *" here and cast at free() time, or have it be a "char *". Since this is not a public API with any sort of API boundary let's use "char *", as is already being done for the "refname" member of the same struct. The tests to mark as passing were found with: rm .prove; GIT_SKIP_TESTS=t0027 prove -j8 --state=save t[0-9]*.sh :: --immediate # apply & compile this change prove -j8 --state=failed :: --immediate I.e. the ones that were newly passing when the --state=failed command was run. I left out "t3040-subprojects-basic.sh" and "t4131-apply-fake-ancestor.sh" to to optimization-level related differences similar to the ones noted in[1], except that these would be something the current 'linux-leaks' job would run into. 1. https://lore.kernel.org/git/cover-v3-0.6-00000000000-20211022T175227Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-08-17rebase -i: support --committer-date-is-author-datePhillip Wood1-1/+0
Rebase is implemented with two different backends - 'apply' and 'merge' each of which support a different set of options. In particular the apply backend supports a number of options implemented by 'git am' that are not implemented in the merge backend. This means that the available options are different depending on which backend is used which is confusing. This patch adds support for the --committer-date-is-author-date option to the merge backend. This option uses the author date of the commit that is being rewritten as the committer date when the new commit is created.

2019-07-31rebase -r: support merge strategies other than `recursive`Johannes Schindelin1-10/+0
We already support merge strategies in the sequencer, but only for `pick` commands. With this commit, we now also support them in `merge` commands. The approach is simple: if any merge strategy option is specified, or if any merge strategy other than `recursive` is specified, we simply spawn the `git merge` command. Otherwise, we handle the merge in-process just as before. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-06-27git-rebase: error out when incompatible options passedElijah Newren1-8/+8
git rebase has three different types: am, merge, and interactive, all of which are implemented in terms of separate scripts. am builds on git-am, merge builds on git-merge-recursive, and interactive builds on git-cherry-pick. We make use of features in those lower-level commands in the different rebase types, but those features don't exist in all of the lower level commands so we have a range of incompatibilities. Previously, we just accepted nearly any argument and silently ignored whichever ones weren't implemented for the type of rebase specified. Change this so the incompatibilities are documented, included in the testsuite, and tested for at runtime with an appropriate error message shown. Some exceptions I left out: * --merge and --interactive are technically incompatible since they are supposed to run different underlying scripts, but with a few small changes, --interactive can do everything that --merge can. In fact, I'll shortly be sending another patch to remove git-rebase--merge and reimplement it on top of git-rebase--interactive. * One could argue that --interactive and --quiet are incompatible since --interactive doesn't implement a --quiet mode (perhaps since cherry-pick itself does not implement one). However, the interactive mode is more quiet than the other modes in general with progress messages, so one could argue that it's already quiet.

2018-06-27t3422: new testcases for checking when incompatible options passedElijah Newren1-0/+88
git rebase is split into three types: am, merge, and interactive. Various options imply different types, and which mode we are using determine which sub-script (git-rebase--$type) is executed to finish the work. Not all options work with all types, so add tests for combinations where we expect to receive an error rather than having options be silently ignored.
