2020-11-19t4*: adjust the references to the default branch name "main"Johannes Schindelin
Carefully excluding t4013 and t4015, which see independent development elsewhere at the time of writing, we use `main` as the default branch name in t4*. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t4*.sh t4211/*.export && git checkout HEAD -- t4013\*) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

2020-11-19tests: mark tests relying on the current default for `init.defaultBranch`Johannes Schindelin
In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/ t/ \ t/ \ t/ t/ \ t/ t/ \ t/ \ t/ \ t/ t/ \ t/ t/ \ t/ \ t/ t/ \ t/ t/ \ t/ t/ \ t/ t/ \ t/ \ t/ \ t/ t/ \ t/ \ t/ t/ \ t/ We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch. Manual analysis revealed that only five of these tests actually require a specific default branch name to pass; They were modified thusly: $ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <> Signed-off-by: Junio C Hamano <>

Test cleanup. * ma/test-quote-cleanup: t4104: modernize and simplify quoting t: don't spuriously close and reopen quotes
2020-08-06t: don't spuriously close and reopen quotesMartin Ågren
In the test scripts, the recommended style is, e.g.: test_expect_success 'name' ' do-something somehow && do-some-more testing ' When using this style, any single quote in the multi-line test section is actually closing the lone single quotes that surround it. It can be a non-issue in practice: test_expect_success 'sed a little' ' sed -e 's/hi/lo/' in >out # "ok": no whitespace in s/hi/lo/ ' Or it can be a bug in the test, e.g., because variable interpolation happens before the test even begins executing: v=abc test_expect_success 'variable interpolation' ' v=def && echo '"$v"' # abc ' Change several such in-test single quotes to use double quotes instead or, in a few cases, drop them altogether. These were identified using some crude grepping. We're not fixing any test bugs here, but we're hopefully making these tests slightly easier to grok and to maintain. There are legitimate use cases for closing a quote and opening a new one, e.g., both '\'' and '"'"' can be used to produce a literal single quote. I'm not touching any of those here.

2018-09-11rerere: avoid buffer overrunElijah Newren
check_one_conflict() compares `i` to `active_nr` in two places to avoid buffer overruns, but left out an important third location. The code did used to have a check here comparing i to active_nr, back before commit fb70a06da2f1 ("rerere: fix an off-by-one non-bug", 2015-06-28), however the code at the time used an 'if' rather than a 'while' meaning back then that this loop could not have read past the end of the array, making the check unnecessary and it was removed. Unfortunately, in commit 5eda906b2873 ("rerere: handle conflicts with multiple stage #1 entries", 2015-07-24), the 'if' was changed to a 'while' and the check comparing i and active_nr was not re-instated, leading to this problem.

2018-08-06rerere: recalculate conflict ID when unresolved conflict is committedThomas Gummerer
Currently when a user doesn't resolve a conflict, commits the results, and does an operation which creates another conflict, rerere will use the ID of the previously unresolved conflict for the new conflict. This is because the conflict is kept in the MERGE_RR file, which 'rerere' reads every time it is invoked. After the new conflict is solved, rerere will record the resolution with the ID of the old conflict. So in order to replay the conflict, both merges would have to be re-done, instead of just the last one, in order for rerere to be able to automatically resolve the conflict. Instead of that, assign a new conflict ID if there are still conflicts in a file and the file had conflicts at a previous step. This ID matches the conflict we actually resolved at the corresponding step. Note that there are no backwards compatibility worries here, as rerere would have failed to even normalize the conflict before this patch series.

2018-08-06rerere: teach rerere to handle nested conflictsThomas Gummerer
Currently rerere can't handle nested conflicts and will error out when it encounters such conflicts. Do that by recursively calling the 'handle_conflict' function to normalize the conflict. Note that a conflict like this would only be produced if a user commits a file with conflict markers, and gets a conflict including that in a susbsequent operation. The conflict ID calculation here deserves some explanation: As we are using the same handle_conflict function, the nested conflict is normalized the same way as for non-nested conflicts, which means the ancestor in the diff3 case is stripped out, and the parts of the conflict are ordered alphabetically. The conflict ID is however is only calculated in the top level handle_conflict call, so it will include the markers that 'rerere' adds to the output. e.g. say there's the following conflict: <<<<<<< HEAD 1 ======= <<<<<<< HEAD 3 ======= 2 >>>>>>> branch-2 >>>>>>> branch-3~ it would be recorde as follows in the preimage: <<<<<<< 1 ======= <<<<<<< 2 ======= 3 >>>>>>> >>>>>>> and the conflict ID would be calculated as sha1(1<NUL><<<<<<< 2 ======= 3 >>>>>>><NUL>) Stripping out vs. leaving the conflict markers in place in the inner conflict should have no practical impact, but it simplifies the implementation.

2018-08-06rerere: fix crash with files rerere can't handleThomas Gummerer
Currently when a user does a conflict resolution and ends it (in any way that calls 'git rerere' again) with a file 'rerere' can't handle, subsequent rerere operations that are interested in that path, such as 'rerere clear' or 'rerere forget <path>' will fail, or even worse in the case of 'rerere clear' segfault. Such states include nested conflicts, or a conflict marker that doesn't have any match. This is because 'git rerere' calculates a conflict file and writes it to the MERGE_RR file. When the user then changes the file in any way rerere can't handle, and then calls 'git rerere' on it again to record the conflict resolution, the handle_file function fails, and removes the 'preimage' file in the rr-cache in the process, while leaving the ID in the MERGE_RR file. Now when 'rerere clear' is run, it reads the ID from the MERGE_RR file, however the 'fit_variant' function for the ID is never called as the 'preimage' file does not exist anymore. This means 'collection->status' in 'has_rerere_resolution' is NULL, and the command will crash. To fix this, remove the rerere ID from the MERGE_RR file in the case when we can't handle it, just after the 'preimage' file was removed and remove the corresponding variant from .git/rr-cache/. Removing it unconditionally is fine here, because if the user would have resolved the conflict and ran rerere, the entry would no longer be in the MERGE_RR file, so we wouldn't have this problem in the first place, while if the conflict was not resolved. Currently there is nothing left in this folder, as the 'preimage' was already deleted by the 'handle_file' function, so 'remove_variant' is a no-op. Still call the function, to make sure we clean everything up, in case we add some other files corresponding to a variant in the future. Note that other variants that have the same conflict ID will not be touched. Signed-off-by: Thomas Gummerer <> Signed-off-by: Junio C Hamano <>

2017-08-22rerere: allow approxidate in gc.rerereResolved/gc.rerereUnresolvedJunio C Hamano
These two configuration variables are described in the documentation to take an expiry period expressed in the number of days: gc.rerereResolved:: Records of conflicted merge you resolved earlier are kept for this many days when 'git rerere gc' is run. The default is 60 days. gc.rerereUnresolved:: Records of conflicted merge you have not resolved are kept for this many days when 'git rerere gc' is run. The default is 15 days. There is no strong reason not to allow a more general "approxidate" expiry specification, e.g. "5.days.ago", or "never". Rename the config_get_expiry() helper introduced in the previous step to git_config_get_expiry_in_days() and move it to a more generic place, config.c, and use date.c::parse_expiry_date() to do so. Give it an ability to allow the caller to tell among three cases (i.e. there is no "gc.rerereResolved" config, there is and it is correctly parsed into the *expiry variable, and there was an error in parsing the given value). The current caller can work correctly without using the return value, though. In the future, we may find other variables that only allow an integer that specifies "this many days" or other unit of time, and when it happens we may need to drop "_days" suffix from the name of the function and instead pass the "scale" value as another parameter. But this will do for now. Signed-off-by: Junio C Hamano <>

This won't work if there is no entry in the database when the test begins. Instead, clear the rerere database, and populate it with a few known entries (which are bogus, but for the purpose of testing "garbage collection", it does not matter---we want to make sure we collect old cruft, even if the files are corrupt rerere database entries), and use them for the expiry test.

2016-04-06rerere: adjust 'forget' to multi-variant world orderJunio C Hamano
Because conflicts with the same contents inside conflict blocks enclosed by "<<<<<<<" and ">>>>>>>" can now have multiple variants to help three-way merge to adjust to the differences outside the conflict blocks, "rerere forget $path" needs to be taught that there may be multiple recorded resolutions that share the same conflict hash (which groups the conflicts with "the same contents inside conflict blocks"), among which there are some that would not be relevant to the conflict we are looking at. These "other variants" that happen to share the same conflict hash should not be cleared, and the variant that would apply to the current conflict may not be the zero-th one (which is the only one that is cleared by the current code). After finding the conflict hash, iterate over the existing variants and try to resolve the conflict using each of them to find the one that "cleanly" resolves the current conflict. That is the one we want to forget and record the preimage for, so that the user can record the corrected resolution. Signed-off-by: Junio C Hamano <>

2016-03-15rerere: do use multiple variantsJunio C Hamano
This enables the multiple-variant support for real. Multiple conflicts of the same shape can have differences in contexts where they appear, interfering the replaying of recorded resolution of one conflict to another, and in such a case, their resolutions are recorded as different variants under the same conflict ID. We still need to adjust garbage collection codepaths for this change, but the basic "replay" functionality is functional with this change. Signed-off-by: Junio C Hamano <>

If by some accident there is only $GIT_DIR/rr-cache/$ID directory existed, we wouldn't have recorded a preimage for a conflict that is newly encountered, which would mean after a manual resolution, we wouldn't have recorded it by storing the postimage, because the logic used to be "if there is no rr-cache/$ID directory, then we are the first so record the preimage". Instead, record preimage if we do not have one. In addition, if there is only $GIT_DIR/rr-cache/$ID/postimage without corresponding preimage, we would have tried to call into merge() and punted.

2010-07-14rerere: fix overeager gcSZEDER Gábor
'rerere gc' prunes resolutions of conflicted merges that occurred long time ago, and when doing so it takes the creation time of the conflicted automerge results into account. This can cause the loss of frequently used conflict resolutions (e.g. long-living topic branches are merged into a regularly rebuilt integration branch (think of git's pu)) when they become old enough to exceed 'rerere gc's threshold. To prevent the loss of valuable merge resolutions 'rerere' will (1) update the timestamp of the recorded conflict resolution (i.e. 'postimage') each time when encountering and resolving the same merge conflict, and (2) take this timestamp, i.e. the time of the last usage into account when gc'ing.

If you want to reuse the rerere cache in another repository, and set a symbolic link to it, you do not want to have the two repositories interfer with each other by accessing the _same_ MERGE_RR. For example, if you use contrib/git-new-workdir to set up a second working directory, and you have a conflict in one working directory, but commit in the other working directory first, the wrong "resolution" will be recorded. The easy solution is to move MERGE_RR out of the rr-cache/ directory, which also corresponds with the notion that rr-cache/ contains cached resolutions, not some intermediate temporary states.

This patch enforces parsing rules so that markers match in the right order, and when ambiguous, the command does not autoresolve the conflicted file.

This patch changes all instances of tr using NULs to use "perl -pe 'y///'" instead. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
