2019-09-30Merge branch 'dl/rebase-i-keep-base'Libravatar Junio C Hamano1-1/+1
"git rebase --keep-base <upstream>" tries to find the original base of the topic being rebased and rebase on top of that same base, which is useful when running the "git rebase -i" (and its limited variant "git rebase -x"). The command also has learned to fast-forward in more cases where it can instead of replaying to recreate identical commits. * dl/rebase-i-keep-base: rebase: teach rebase --keep-base rebase tests: test linear branch topology rebase: fast-forward --fork-point in more cases rebase: fast-forward --onto in more cases rebase: refactor can_fast_forward into goto tower t3432: test for --no-ff's interaction with fast-forward t3432: distinguish "noop-same" v.s.

2019-09-09Merge branch 'bc/reread-attributes-during-rebase'Libravatar Junio C Hamano1-0/+36
The "git am" based backend of "git rebase" ignored the result of updating ".gitattributes" done in one step when replaying subsequent steps. * bc/reread-attributes-during-rebase: am: reload .gitattributes after patching it path: add a function to check for path suffix
2019-09-03am: reload .gitattributes after patching itLibravatar brian m. carlson1-0/+36
When applying multiple patches with git am, or when rebasing using the am backend, it's possible that one of our patches has updated a gitattributes file. Currently, we cache this information, so if a file in a subsequent patch has attributes applied, the file will be written out with the attributes in place as of the time we started the rebase or am operation, not with the attributes applied by the previous patch. This problem does not occur when using the -m or -i flags to rebase. To ensure we write the correct data into the working tree, expire the cache after each patch that touches a path ending in ".gitattributes". Since we load these attributes in multiple separate files, we must expire them accordingly. Verify that both the am and rebase code paths work correctly, including the conflict marker size with am -3.

2019-08-27rebase: fast-forward --onto in more casesLibravatar Denton Liu1-1/+1
Before, when we had the following graph, A---B---C (master) \ D (side) running 'git rebase --onto master... master side' would result in D being always rebased, no matter what. However, the desired behavior is that rebase should notice that this is fast-forwardable and do that instead. Add detection to `can_fast_forward` so that this case can be detected and a fast-forward will be performed. First of all, rewrite the function to use gotos which simplifies the logic. Next, since the options.upstream && !oidcmp(&options.upstream->object.oid, &options.onto->object.oid) conditions were removed in `cmd_rebase`, we reintroduce a substitute in `can_fast_forward`. In particular, checking the merge bases of `upstream` and `head` fixes a failing case in t3416. The abbreviated graph for t3416 is as follows: F---G topic / A---B---C---D---E master and the failing command was git rebase --onto master...topic F topic Before, Git would see that there was one merge base (C), and the merge and onto were the same so it would incorrectly return 1, indicating that we could fast-forward. This would cause the rebased graph to be 'ABCFG' when we were expecting 'ABCG'. With the additional logic, we detect that upstream and head's merge base is F. Since onto isn't F, it means we're not rebasing the full set of commits from master..topic. Since we're excluding some commits, a fast-forward cannot be performed and so we correctly return 0. Add '-f' to test cases that failed as a result of this change because they were not expecting a fast-forward so that a rebase is forced.

2019-03-20rebase: remove the rebase.useBuiltin settingLibravatar Ævar Arnfjörð Bjarmason1-0/+16
Remove the rebase.useBuiltin setting, which was added as an escape hatch to disable the builtin version of rebase first released with Git 2.20. See [1] for the initial implementation of rebase.useBuiltin, and [2] and [3] for the documentation and corresponding GIT_TEST_REBASE_USE_BUILTIN option. Carrying the legacy version is a maintenance burden as seen in 7e097e27d3 ("legacy-rebase: backport -C<n> and --whitespace=<option> checks", 2018-11-20) and 9aea5e9286 ("rebase: fix regression in rebase.useBuiltin=false test mode", 2019-02-13). Since the built-in version has been shown to be stable enough let's remove the legacy version. As noted in [3] having use_builtin_rebase() shell out to get its config doesn't make any sense anymore, that was done for the purposes of spawning the legacy rebase without having modified any global state. Let's instead handle this case in rebase_config(). There's still a bunch of references to git-legacy-rebase in po/*.po, but those will be dealt with in time by the i18n effort. Even though this configuration variable only existed two releases let's not entirely delete the entry from the docs, but note its absence. Individual versions of git tend to be around for a while due to distro packaging timelines, so e.g. if we're "lucky" a given version like 2.21 might be installed on say OSX for half a decade. That'll mean some people probably setting this in config, and then when they later wonder if it's needed they can Google search the config option name or check it in git-config. It also allows us to refer to the docs from the warning for details. 1. 55071ea248 ("rebase: start implementing it as a builtin", 2018-08-07) 2. d8d0a546f0 ("rebase doc: document rebase.useBuiltin", 2018-11-14) 3. 62c23938fa ("tests: add a special setup where rebase.useBuiltin is off", 2018-11-14) 3. https://public-inbox.org/git/nycvar.QRO.7.76.6.1903141544110.41@tvgsbejvaqbjf.bet/ Acked-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-04built-in rebase: set ORIG_HEAD just once, before the rebaseLibravatar Johannes Schindelin1-1/+1
Technically, the scripted version set ORIG_HEAD only in two spots (which really could have been one, because it called `git checkout $onto^0` to start the rebase and also if it could take a shortcut, and in both cases it called `git update-ref $orig_head`). Practically, it *implicitly* reset ORIG_HEAD whenever `git reset --hard` was called. However, what we really want is that it is set exactly once, at the beginning of the rebase. So let's do that.

2014-07-16rebase: omit patch-identical commits with --fork-pointLibravatar John Keeping1-0/+23
When the `--fork-point` argument was added to `git rebase`, we changed the value of $upstream to be the fork point instead of the point from which we want to rebase. When $orig_head..$upstream is empty this does not change the behaviour, but when there are new changes in the upstream we are no longer checking if any of them are patch-identical with changes in $upstream..$orig_head. Fix this by introducing a new variable to hold the fork point and using this to restrict the range as an extra (negative) revision argument so that the set of desired revisions becomes (in fork-point mode): git rev-list --cherry-pick --right-only \ $upstream...$orig_head ^$fork_point This allows us to correctly handle the scenario where we have the following topology: C --- D --- E <- dev / B <- master@{1} / o --- B' --- C* --- D* <- master where: - B' is a fixed-up version of B that is not patch-identical with B; - C* and D* are patch-identical to C and D respectively and conflict textually if applied in the wrong order; - E depends textually on D. The correct result of `git rebase master dev` is that B is identified as the fork-point of dev and master, so that C, D, E are the commits that need to be replayed onto master; but C and D are patch-identical with C* and D* and so can be dropped, so that the end result is: o --- B' --- C* --- D* --- E <- dev If the fork-point is not identified, then picking B onto a branch containing B' results in a conflict and if the patch-identical commits are not correctly identified then picking C onto a branch containing D (or equivalently D*) results in a conflict. This change allows us to handle both of these cases, where previously we either identified the fork-point (with `--fork-point`) but not the patch-identical commits *or* (with `--no-fork-point`) identified the patch-identical commits but not the fact that master had been rewritten.

When no arguments are specified, $switch_to is empty so we end up passing the empty string to "git merge-base --fork-point", which causes an error. git-rebase carries on at this point, but in fact we have failed to apply the fork-point operation. It turns out that the test in t3400 that was meant to test this didn't actually need the fork-point behaviour, so enhance it to make sure that the fork-point is applied correctly.

2013-12-10rebase: use reflog to find common base with upstreamLibravatar John Keeping1-2/+4
Commit 15a147e (rebase: use @{upstream} if no upstream specified, 2011-02-09) says: Make it default to 'git rebase @{upstream}'. That is also what 'git pull [--rebase]' defaults to, so it only makes sense that 'git rebase' defaults to the same thing. but that isn't actually the case. Since commit d44e712 (pull: support rebased upstream + fetch + pull --rebase, 2009-07-19), pull has actually chosen the most recent reflog entry which is an ancestor of the current branch if it can find one. Add a '--fork-point' argument to git-rebase that can be used to trigger this behaviour. This option is turned on by default if no non-option arguments are specified on the command line, otherwise we treat an upstream specified on the command-line literally.

2013-04-23rebase: find orig_head unambiguouslyLibravatar Phil Hord1-0/+7
When we 'git rebase $upstream', git uses 'rev-parse --verify $current_branch' to find ORIG_HEAD. But if $current_branch is ambiguous, 'rev-parse --verify' emits a warning and returns a SHA1 anyway. When the wrong ambiguous choice is used, git-rebase fails non-gracefully: it emits a warning about failing to lock $current_branch, an error about being unable to checkout $current_branch again, and it might even decide the rebase is a fast-forward when it is not. In the 'rebase $upstream' case, we already know the unambiguous spelling of $current_branch is "HEAD". Fix git-rebase to find $orig_head unambiguously.

'git rebase' without arguments is currently not supported. Make it default to 'git rebase @{upstream}'. That is also what 'git pull [--rebase]' defaults to, so it only makes sense that 'git rebase' defaults to the same thing. Defaulting to @{upstream} will make it possible to run e.g. 'git rebase -i' without arguments, which is probably a quite common use case. It also improves the scenario where you have multiple branches that rebase against a remote-tracking branch, where you currently have to choose between the extra network delay of 'git pull' or the slightly awkward keys to enter 'git rebase @{u}'. The error reporting when no upstream is configured for the current branch or when no branch is checked out is reused from git-pull.sh.

While at it, fix the usage message to explain that the upstream argument is mandatory.

2010-01-25tests: consolidate CR removal/addition functionsLibravatar Stephen Boyd1-4/+0
append_cr(), remove_cr(), q_to_nul() and q_to_cr() are defined in multiple tests. Consolidate them into test-lib.sh so we can stop redefining them. The use of remove_cr() in t0020 to test for a CR is replaced with a new function has_cr() to accurately reflect what is intended (the output of remove_cr() was being thrown away).

2009-08-05Allow mailsplit (and hence git-am) to handle mails with CRLF line-endingsLibravatar Junio C Hamano1-2/+24
It is not that uncommon to have mails with DOS line-ending, notably Thunderbird and web mailers like Gmail (when saving what they call "original" message). So modify mailsplit to convert CRLF line-endings to just LF. Since git-rebase is built on top of git-am, add an option to mailsplit to be used by git-am when it is acting on behalf of git-rebase, to refrain from doing this conversion. And add a test to make sure that rebase still works. Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-18am, rebase: teach quiet optionLibravatar Stephen Boyd1-6/+13
git-am and git-rebase are talkative scripts. Teach them to be quiet when told, allowing them to speak only when they fail or experience errors. The quiet option is maintained when git-am or git-rebase fails to apply a patch. This means subsequent --resolved, --continue, --skip, --abort invocations will be quiet if the original invocation was quiet. Drop a handful of >&2 redirection; the rest of the program sends all the info messages to stdout, not to stderr.

2009-03-19test-lib: Introduce test_chmod and use it instead of update-index --chmodLibravatar Johannes Sixt1-2/+2
This function replaces sequences of 'chmod +x' and 'git update-index --chmod=+x' in the test suite, whose purpose is to help filesystems that need core.filemode=false. Two places where only 'chmod +x' was used we also use this new function. The function calls 'git update-index --chmod' without checking core.filemode (unlike some of the call sites did). We do this because the call sites *expect* that the executable bit ends up in the index (ie. it is not the purpose of the call sites to *test* whether git treats 'chmod +x' and 'update-index --chmod=+x' correctly). Therefore, on filesystems with core.filemode=true the 'git update-index --chmod' is a no-op. The function uses --add with update-index to help one call site in t6031-merge-recursive. It makes no difference for the other callers. Signed-off-by: Johannes Sixt <j6t@kdbg.org>
