2020-09-02fetch: no FETCH_HEAD display if --no-write-fetch-headLibravatar Jonathan Tan2-10/+15
887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update", 2020-08-18) introduced the ability to disable writing to FETCH_HEAD during fetch, but did not suppress the "<source> -> FETCH_HEAD" message when this ability is used. This message is misleading in this case, because FETCH_HEAD is not written. Also, because "fetch" is used to lazy-fetch missing objects in a partial clone, this significantly clutters up the output in that case since the objects to be fetched are potentially numerous. Therefore, suppress this message when --no-write-fetch-head is passed (but not when --dry-run is set).

2020-08-26revision: set rev_input_given in handle_revision_arg()Libravatar Jeff King2-0/+15
Commit 7ba826290a (revision: add rev_input_given flag, 2017-08-02) added a flag to rev_info to tell whether we got any revision arguments. As explained there, this is necessary because some revision arguments may not produce any pending traversal objects, but should still inhibit default behaviors (e.g., a glob that matches nothing). However, it only set the flag in the globbing code, but not for revisions we get on the command-line or via stdin. This leads to two problems: - the command-line code keeps its own separate got_rev_arg flag; this isn't wrong, but it's confusing and an extra maintenance burden - even specifically-named rev arguments might end up not adding any pending objects: if --ignore-missing is set, then specifying a missing object is a noop rather than an error. And that leads to some user-visible bugs: - when deciding whether a default rev like "HEAD" should kick in, we check both got_rev_arg and rev_input_given. That means that "--ignore-missing $ZERO_OID" works on the command-line (where we set got_rev_arg) but not on --stdin (where we don't) - when rev-list decides whether it should complain that it wasn't given a starting point, it relies on rev_input_given. So it can't even get the command-line "--ignore-missing $ZERO_OID" right Let's consistently set the flag if we got any revision argument. That lets us clean up the redundant got_rev_arg, and fixes both of those bugs (but note there are three new tests: we'll confirm the already working git-log command-line case). A few implementation notes: - conceptually we want to set the flag whenever handle_revision_arg() finds an actual revision arg ("handles" it, you might say). But it covers a ton of cases with early returns. Rather than annotating each one, we just wrap it and use its success exit-code to set the flag in one spot. - the new rev-list test is in t6018, which is titled to cover globs. This isn't exactly a glob, but it made sense to stick it with the other tests that handle the "even though we got a rev, we have no pending objects" case, which are globs. - the tests check for the oid of a missing object, which it's pretty clear --ignore-missing should ignore. You can see the same behavior with "--ignore-missing a-ref-that-does-not-exist", because --ignore-missing treats them both the same. That's perhaps less clearly correct, and we may want to change that in the future. But the way the code and tests here are written, we'd continue to do the right thing even if it does.

2020-08-25refs: remove lookup cache for reference-transaction hookLibravatar Patrick Steinhardt1-3/+10
When adding the reference-transaction hook, there were concerns about the performance impact it may have on setups which do not make use of the new hook at all. After all, it gets executed every time a reftx is prepared, committed or aborted, which linearly scales with the number of reference-transactions created per session. And as there are code paths like `git push` which create a new transaction for each reference to be updated, this may translate to calling `find_hook()` quite a lot. To address this concern, a cache was added with the intention to not repeatedly do negative hook lookups. Turns out this cache caused a regression, which was fixed via e5256c82e5 (refs: fix interleaving hook calls with reference-transaction hook, 2020-08-07). In the process of discussing the fix, we realized that the cache doesn't really help even in the negative-lookup case. While performance tests added to benchmark this did show a slight improvement in the 1% range, this really doesn't warrent having a cache. Furthermore, it's quite flaky, too. E.g. running it twice in succession produces the following results: Test master pks-reftx-hook-remove-cache -------------------------------------------------------------------------- 1400.2: update-ref 2.79(2.16+0.74) 2.73(2.12+0.71) -2.2% 1400.3: update-ref --stdin 0.22(0.08+0.14) 0.21(0.08+0.12) -4.5% Test master pks-reftx-hook-remove-cache -------------------------------------------------------------------------- 1400.2: update-ref 2.70(2.09+0.72) 2.74(2.13+0.71) +1.5% 1400.3: update-ref --stdin 0.21(0.10+0.10) 0.21(0.08+0.13) +0.0% One case notably absent from those benchmarks is a single executable searching for the hook hundreds of times, which is exactly the case for which the negative cache was added. p1400.2 will spawn a new update-ref for each transaction and p1400.3 only has a single reference-transaction for all reference updates. So this commit adds a third benchmark, which performs an non-atomic push of a thousand references. This will create a new reference transaction per reference. But even for this case, the negative cache doesn't consistently improve performance: Test master pks-reftx-hook-remove-cache -------------------------------------------------------------------------- 1400.4: nonatomic push 6.63(6.50+0.13) 6.81(6.67+0.14) +2.7% 1400.4: nonatomic push 6.35(6.21+0.14) 6.39(6.23+0.16) +0.6% 1400.4: nonatomic push 6.43(6.31+0.13) 6.42(6.28+0.15) -0.2% So let's just remove the cache altogether to simplify the code.

2020-08-24fetch-pack: make packfile URIs work with transfer.fsckobjectsLibravatar Jonathan Tan1-0/+53
When fetching with packfile URIs and transfer.fsckobjects=1, use the --fsck-objects instead of the --strict flag when invoking index-pack so that links are not checked, only objects. This is because incomplete links are expected. (A subsequent connectivity check will be done when all the packs have been downloaded regardless of whether transfer.fsckobjects is set.) This is similar to 98a2ea46c2 ("fetch-pack: do not check links for partial fetch", 2018-03-15), but for packfile URIs instead of partial clones.

2020-08-22checkout, restore: make pathspec recursiveLibravatar René Scharfe2-3/+28
The pathspec given to git checkout and git restore is used with both tree_entry_interesting (via read_tree_recursive) and match_pathspec (via ce_path_match). The latter effectively only supports recursive matching regardless of the value of the pathspec flag "recursive", which is unset here. That causes different match results for pathspecs with wildcards, and can lead checkout and restore in no-overlay mode to remove entries instead of modifying them. Enable recursive matching for both checkout and restore to make matching consistent. Setting the flag in checkout_main() technically also affects git switch, but since that command doesn't accept pathspecs at all this has no actual consequence.

2020-08-21diff: index-line: respect --abbrev in object's nameLibravatar Đoàn Trần Công Danh4-0/+90
A handful of Git's commands respect `--abbrev' for customizing length of abbreviation of object names. For diff-family, Git supports 2 different options for 2 different purposes, `--full-index' for showing diff-patch object's name in full, and `--abbrev' to customize the length of object names in diff-raw and diff-tree header lines, without any options to customise the length of object names in diff-patch format. When working with diff-patch format, we only have two options, either full index, or default abbrev length. Although, that behaviour is documented, it doesn't stop users from trying to use `--abbrev' with the hope of customising diff-patch's objects' name's abbreviation. Let's allow the blob object names shown on the "index" line to be abbreviated to arbitrary length given via the "--abbrev" option. To preserve backward compatibility with old script that specify both `--full-index' and `--abbrev', always show full object id if `--full-index' is specified.

From 72f936b1 (t4013: make test hash independent, 2020-02-07), we started to adjust metadata of git-diff's output in order to ignore uninteresting metadata which is dependent of underlying hash algorithm. However, we forgot to special case all-zero object names, which is special for missing objects, in consequence, we could't catch possible future bugs where object names is all-zeros including but not limited to: * show intend-to-add entry * deleted entry * diff between index and working tree with new file We also mistakenly munged file-modes as if they were object names abbreviated to 6 hexadecimal digits. In addition, in the upcoming change, we would like to test for customizing the length of abbreviated blob objects on the index line, which is not supported by current diff-processor logic.

2020-08-21p5302: count up to online-cpus for thread testsLibravatar Jeff King1-23/+24
When PERF_EXTRA is enabled, p5302 checks the performance of index-pack with various numbers of threads. This can be useful for deciding what the default should be (which is currently capped at 3 threads based on the results of this script). However, we only go up to 8 threads, and modern machines may have more. Let's get the number of CPUs from test-tool, and test various numbers of threads between one and that maximum. Note that the current tests aren't all identical, as we have to set GIT_FORCE_THREADS for the --threads=1 test (which measures the overhead of starting a single worker thread versus the "0" case of using the main thread). To keep the loop simple, we'll keep the "0" case out of it, and set GIT_FORCE_THREADS=1 for all of the other cases (it's a noop for all but the "1" case, since numbers higher than 1 would always need threads). Note also that we could skip running "test-tool" if PERF_EXTRA isn't set. However, there's some small value in knowing the number of threads, so that we can mark each test as skipped in the output.

2020-08-21p5302: disable thread-count parameter tests by defaultLibravatar Jeff King3-5/+16
The primary function of the perf suite is to detect regressions (or improvements) between versions of Git. The only numbers we show a direct comparison for are timings between the same test run on two different versions. However, it can sometimes be used to collect other information. For instance, p5302 runs the same index-pack operation with different thread counts. The output doesn't directly compare these, but anybody interested in working on index-pack can manually compare the results. For a normal regression run of the full perf-suite, though, this incurs a significant cost to generate numbers nobody will actually look at; about 25% of the total time of the test suite is spent in p5302. And the low-thread-count runs are the most expensive part of it, since they're (unsurprisingly) not using as many threads. Let's skip these tests by default, but make it possible for people working on index-pack to still run them by setting an environment variable. Rather than make this specific to p5302, let's introduce a generic mechanism. This makes it possible to run the full suite with every possible test if somebody really wants to burn some CPU.

2020-08-20fetch-pack: in partial clone, pass --promisorLibravatar Jonathan Tan1-0/+16
When fetching a pack from a promisor remote, the corresponding .promisor file needs to be created. "fetch-pack" originally did this by passing "--promisor" to "index-pack", but in 5374a290aa ("fetch-pack: write fetched refs to .promisor", 2019-10-16), "fetch-pack" was taught to do this itself instead, because it needed to store ref information in the .promisor file. This causes a problem with superprojects when transfer.fsckobjects is set, because in the current implementation, it is "index-pack" that calls fsck_finish() to check the objects; before 5374a290aa, fsck_finish() would see that .gitmodules is a promisor object and tolerate it being missing, but after, there is no .promisor file (at the time of the invocation of fsck_finish() by "index-pack") to tell it that .gitmodules is a promisor object, so it returns an error. Therefore, teach "fetch-pack" to pass "--promisor" to index pack once again. "fetch-pack" will subsequently overwrite this file with the ref information. An alternative is to instead move object checking to "fetch-pack", and let "index-pack" only index the files. However, since "index-pack" has to inflate objects in order to index them, it seems reasonable to also let it check the objects (which also require inflated files).

2020-08-19diff: teach --stat to ignore uninteresting modificationsLibravatar Matthew Rogers1-2/+36
When options such as --ignore-space-change are in use, files with modifications can have no interesting textual changes worth showing. In such cases, "git diff --stat" shows 0 lines of additions and deletions. Teach "git diff --stat" not to show such a path in its output, which would be more natural. However, we don't want to prevent the display of all files that have 0 effective diffs since they could be the result of a rename, permission change, or other similar operation that may still be of interest so we special case additions and deletions as they are always interesting.

2020-08-19rebase: add --reset-author-dateLibravatar Rohit Ashiwal1-13/+21
The previous commit introduced --ignore-date flag to rebase -i, but the name is rather vague as it does not say whether the author date or the committer date is ignored. Add an alias to convey the precise purpose. Helped-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Rohit Ashiwal <rohit.ashiwal265@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-08-19rebase -i: support --ignore-dateLibravatar Phillip Wood1-0/+56
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 --ignore-date option to the merge backend. This option uses the current time as the author date rather than reusing the original author date when rewriting commits. We take care to handle the combination of --ignore-date and --committer-date-is-author-date in the same way as the apply backend.

2020-08-18promisor-remote: lazy-fetch objects in subprocessLibravatar Jonathan Tan4-7/+7
Teach Git to lazy-fetch missing objects in a subprocess instead of doing it in-process. This allows any fatal errors that occur during the fetch to be isolated and converted into an error return value, instead of causing the current command being run to terminate.
