2021-12-22fetch/pull: use the sparse indexLibravatar Derrick Stolee1-0/+2
The 'git fetch' and 'git pull' commands parse the index in order to determine if submodules exist. Without command_requires_full_index=0, this will expand a sparse index, causing slow performance even when there is no new data to fetch. The .gitmodules file will never be inside a sparse directory entry, and even if it was, the index_name_pos() method would expand the sparse index if needed as we search for the path by name. These commands do not iterate over the index, which is the typical thing we are careful about when integrating with the sparse index.

2021-10-29pull: --ff-only should make it a noop when already-up-to-dateLibravatar Junio C Hamano1-1/+28
Earlier, we made sure that "git pull --ff-only" (and "git -c pull.ff=only pull") errors out when our current HEAD is not an ancestor of the tip of the history we are merging, but the condition to trigger the error was implemented incorrectly. Imagine you forked from a remote branch, built your history on top of it, and then attempted to pull from them again. If they have not made any update in the meantime, our current HEAD is obviously not their ancestor, and this new error triggers. Without the --ff-only option, we just report that there is no need to pull; we did the same historically with --ff-only, too. Make sure we do not fail with the recently added check to restore the historical behaviour.

2021-09-09Close object store closer to spawning child processesLibravatar Johannes Schindelin1-2/+1
In many cases where we spawned child processes that _may_ trigger a repack, we explicitly closed the object store first (so that the `repack` process can delete the `.pack` files, which would otherwise not be possible on Windows since files cannot be deleted as long as they as still in use). Wherever possible, we now use the new `close_object_store` bit of the `run_command()` API, to delay closing the object store even further. This makes the code easier to maintain because it is now more obvious that we only release those file handles because of those child processes.

2021-09-08pull: release packs before fetchingLibravatar Johannes Schindelin1-0/+2
On Windows, files cannot be removed nor renamed if there are still handles held by a process. To remedy that, we try to release all open handles to any `.pack` file before e.g. repacking (which would want to remove the original `.pack` file(s) after it is done). Since the `read_cache_unmerged()` and/or the `get_oid()` call in `git pull` can cause `.pack` files to be opened, we need to release the open handles before calling `git fetch`: the latter process might want to spawn an auto-gc, which in turn might want to repack the objects. This commit is similar in spirit to 5bdece0d705 (gc/repack: release packs when needed, 2018-12-15). This fixes https://github.com/git-for-windows/git/issues/3336.

2021-07-22pull: since --ff-only overrides, handle it firstLibravatar Elijah Newren1-8/+8
There are both merge and rebase branches in the logic, and previously both had to handle fast-forwarding. Merge handled that implicitly (because git merge handles it directly), while in rebase it was explicit. Given that the --ff-only flag is meant to override any --rebase or --no-rebase, make the code reflect that by handling --ff-only before the merge-vs-rebase logic. It turns out that this also fixes a bug for submodules. Previously, when --ff-only was given, the code would run `merge --ff-only` on the main module, and then run `submodule update --recursive --rebase` on the submodules. With this change, we still run `merge --ff-only` on the main module, but now run `submodule update --recursive --checkout` on the submodules. I believe this better reflects the intent of --ff-only to have it apply to both the main module and the submodules. (Sidenote: It is somewhat interesting that all merges pass `--checkout` to submodule update, even when `--no-ff` is specified, meaning that it will only do fast-forward merges for submodules. This was discussed in commit a6d7eb2c7a ("pull: optionally rebase submodules (remote submodule changes only)", 2017-06-23). The same limitations apply now as then, so we are not trying to fix this at this time.) Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-06-19pull: cleanup autostash checkLibravatar Felipe Contreras1-9/+7
Currently "git pull --rebase" takes a shortcut in the case a fast-forward merge is possible; run_merge() is called with --ff-only. However, "git merge" didn't have an --autostash option, so, when "git pull --rebase --autostash" was called *and* the fast-forward merge shortcut was taken, then the pull failed. This was fixed in commit f15e7cf5cc (pull: ff --rebase --autostash works in dirty repo, 2017-06-01) by simply skipping the fast-forward merge shortcut. Later on "git merge" learned the --autostash option [a03b55530a (merge: teach --autostash option, 2020-04-07)], and so did "git pull" [d9f15d37f1 (pull: pass --autostash to merge, 2020-04-07)]. Therefore it's not necessary to skip the fast-forward merge shortcut anymore when called with --rebase --autostash. Let's always take the fast-forward merge shortcut by essentially reverting f15e7cf5cc. Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In d18c950a69f (pull: warn if the user didn't say whether to rebase or to merge, 2020-03-09), a new hint was introduced to encourage users to make a conscious decision about whether they want their pull to merge or to rebase by configuring the `pull.rebase` setting. This warning was clearly intended to advise users, but as pointed out in https://lore.kernel.org/git/87ima2rdsm.fsf%40evledraar.gmail.com, it uses `warning()` instead of `advise()`. One consequence is that the advice is not colorized in the same manner as other, similar messages. So let's use `advise()` instead.

2020-11-16pull: check for local submodule modifications with the right rangeLibravatar Philippe Blain1-1/+1
Ever since 'git pull' learned '--recurse-submodules' in a6d7eb2c7a (pull: optionally rebase submodules (remote submodule changes only), 2017-06-23), we check if there are local submodule modifications by checking the revision range 'curr_head --not rebase_fork_point'. The goal of this check is to abort the pull if there are submodule modifications in the local commits being rebased, since this scenario is not supported. However, the actual range of commits being rebased is not 'rebase_fork_point..curr_head', as the logic in 'get_rebase_newbase_and_upstream' reveals, it is 'upstream..curr_head'. If the 'git merge-base --fork-point' invocation in 'get_rebase_fork_point' fails to find a fork point between the current branch and the remote-tracking branch we are pulling from, 'rebase_fork_point' is null and since 4d36f88be7 (submodule: do not pass null OID to setup_revisions, 2018-05-24), 'submodule_touches_in_range' checks 'curr_head' and all its ancestors for submodule modifications. Since it is highly likely that there are submodule modifications in this range (which is in effect the whole history of the current branch), this prevents 'git pull --rebase --recurse-submodules' from succeeding if no fork point exists between the current branch and the remote-tracking branch being pulled. This can happen, for example, when the current branch was forked from a commit which was never recorded in the reflog of the remote-tracking branch we are pulling, as the last two paragraphs of the "Discussion on fork-point mode" section in git-merge-base(1) explain. Fix this bug by passing 'upstream' instead of 'rebase_fork_point' as the 'excl_oid' argument to 'submodule_touches_in_range'.

2020-10-20Documentation: stylistically normalize references to Signed-off-by:Libravatar Bradley M. Kuhn1-1/+1
Ted reported an old typo in the git-commit.txt and merge-options.txt. Namely, the phrase "Signed-off-by line" was used without either a definite nor indefinite article. Upon examination, it seems that the documentation (including items in Documentation/, but also option help strings) have been quite inconsistent on usage when referring to `Signed-off-by`. First, very few places used a definite or indefinite article with the phrase "Signed-off-by line", but that was the initial typo that led to this investigation. So, normalize using either an indefinite or definite article consistently. The original phrasing, in Commit 3f971fc425b (Documentation updates, 2005-08-14), is "Add Signed-off-by line". Commit 6f855371a53 (Add --signoff, --check, and long option-names. 2005-12-09) switched to using "Add `Signed-off-by:` line", but didn't normalize the former commit to match. Later commits seem to have cut and pasted from one or the other, which is likely how the usage became so inconsistent. Junio stated on the git mailing list in <xmqqy2k1dfoh.fsf@gitster.c.googlers.com> a preference to leave off the colon. Thus, prefer `Signed-off-by` (with backticks) for the documentation files and Signed-off-by (without backticks) for option help strings. Additionally, Junio argued that "trailer" is now the standard term to refer to `Signed-off-by`, saying that "becomes plenty clear that we are not talking about any random line in the log message". As such, prefer "trailer" over "line" anywhere the former word fits. However, leave alone those few places in documentation that use Signed-off-by to refer to the process (rather than the specific trailer), or in places where mail headers are generally discussed in comparison with Signed-off-by.

Code which split an argv_array call across multiple lines, like: argv_array_pushl(&args, "one argument", "another argument", "and more", NULL); was recently mechanically renamed to use strvec, which results in mis-matched indentation like: strvec_pushl(&args, "one argument", "another argument", "and more", NULL); Let's fix these up to align the arguments with the opening paren. I did this manually by sifting through the results of: git jump grep 'strvec_.*,$' and liberally applying my editor's auto-format. Most of the changes are of the form shown above, though I also normalized a few that had originally used a single-tab indentation (rather than our usual style of aligning with the open paren). I also rewrapped a couple of obvious cases (e.g., where previously too-long lines became short enough to fit on one), but I wasn't aggressive about it. In cases broken to three or more lines, the grouping of arguments is sometimes meaningful, and it wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec consistently. There's no particular reason we have to do it all at once, or care about interactions between converted and unconverted bits. Because of our preprocessor compat layer, the names are interchangeable to the compiler (so even a definition and declaration using different names is OK). This patch converts all of the files in builtin/ to keep the diff to a manageable size. The conversion was done purely mechanically with: git ls-files '*.c' '*.h' | xargs perl -i -pe ' s/ARGV_ARRAY/STRVEC/g; s/argv_array/strvec/g; ' and then selectively staging files with "git add builtin/".

2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FLibravatar Denton Liu1-4/+4
In the codebase, there are many options which use OPTION_CALLBACK in a plain ol' struct definition. However, we have the OPT_CALLBACK and OPT_CALLBACK_F macros which are meant to abstract these plain struct definitions away. These macros are useful as they semantically signal to developers that these are just normal callback option with nothing fancy happening. Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or OPT_CALLBACK_F where applicable. The heavy lifting was done using the following (disgusting) shell script: #!/bin/sh do_replacement () { tr '\n' '\r' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' | tr '\r' '\n' } for f in $(git ls-files \*.c) do do_replacement <"$f" >"$f.tmp" mv "$f.tmp" "$f" done The result was manually inspected and then reformatted to match the style of the surrounding code. Finally, using `git grep OPTION_CALLBACK \*.c`, leftover results which were not handled by the script were manually transformed.

2020-04-22Merge branch 'en/pull-do-not-rebase-after-fast-forwarding'Libravatar Junio C Hamano1-1/+4
"git pull --rebase" tried to run a rebase even after noticing that the pull results in a fast-forward and no rebase is needed nor sensible, for the past few years due to a mistake nobody noticed. * en/pull-do-not-rebase-after-fast-forwarding: pull: avoid running both merge and rebase
2020-04-22Merge branch 'rs/pull-options-sync-code-and-doc'Libravatar Junio C Hamano1-0/+18
"git pull" shares many options with underlying "git fetch", but some of them were not documented and some of those that would make sense to pass down were not passed down. * rs/pull-options-sync-code-and-doc: pull: pass documented fetch options on pull: remove --update-head-ok from documentation
2020-04-10pull: pass --autostash to mergeLibravatar Denton Liu1-4/+5
Before, `--autostash` only worked with `git pull --rebase`. However, in the last patch, merge learned `--autostash` as well so there's no reason why we should have this restriction anymore. Teach pull to pass `--autostash` to merge, just like it did for rebase. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
