2022-03-23ls-tree: split up "fast path" callbacksLibravatar Ævar Arnfjörð Bjarmason1-74/+125
Make the various if/else in the callbacks for the "fast path" a lot easier to read by just using common functions for the parts that are common, and have per-format callbacks for those parts that are different.

2022-03-23ls-tree: support --object-only option for "git-ls-tree"Libravatar Teng Long1-1/+12
'--object-only' is an alias for '--format=%(objectname)'. It cannot be used together other format-altering options like '--name-only', '--long' or '--format', they are mutually exclusive. The "--name-only" option outputs <filepath> only. Likewise, <objectName> is another high frequency used field, so implement '--object-only' option will bring intuitive and clear semantics for this scenario. Using '--format=%(objectname)' we can achieve a similar effect, but the former is with a lower learning cost(without knowing the format requirement of '--format' option). Even so, if a user is prefer to use "--format=%(objectname)", this is entirely welcome because they are not only equivalent in function, but also have almost identical performance. The reason is this commit also add the specific of "--format=%(objectname)" to the current fast-pathes (builtin formats) to avoid running unnecessary parsing mechanisms. The following performance benchmarks are based on torvalds/linux.git: When hit the fast-path: Benchmark 1: /opt/git/ls-tree-oid-only/bin/git ls-tree -r --object-only HEAD Time (mean ± σ): 83.6 ms ± 2.0 ms [User: 59.4 ms, System: 24.1 ms] Range (min … max): 80.4 ms … 87.2 ms 35 runs Benchmark 1: /opt/git/ls-tree-oid-only/bin/git ls-tree -r --format='%(objectname)' HEAD Time (mean ± σ): 84.1 ms ± 1.8 ms [User: 61.7 ms, System: 22.3 ms] Range (min … max): 80.9 ms … 87.5 ms 35 runs But for a customized format, it will be slower: Benchmark 1: /opt/git/ls-tree-oid-only/bin/git ls-tree -r --format='oid: %(objectname)' HEAD Time (mean ± σ): 96.5 ms ± 2.5 ms [User: 72.9 ms, System: 23.5 ms] Range (min … max): 93.1 ms … 104.1 ms 31 runs Helped-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Teng Long <dyroneteng@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-03-23ls-tree: introduce "--format" optionLibravatar Ævar Arnfjörð Bjarmason1-3/+150
Add a --format option to ls-tree. It has an existing default output, and then --long and --name-only options to emit the default output along with the objectsize and, or to only emit object paths. Rather than add --type-only, --object-only etc. we can just support a --format using a strbuf_expand() similar to "for-each-ref --format". We might still add such options in the future for convenience. The --format implementation is slower than the existing code, but this change does not cause any performance regressions. We'll leave the existing show_tree() unchanged, and only run show_tree_fmt() in if a --format different than the hardcoded built-in ones corresponding to the existing modes is provided. I.e. something like the "--long" output would be much slower with this, mainly due to how we need to allocate various things to do with quote.c instead of spewing the output directly to stdout. The new option of '--format' comes from Ævar Arnfjörð Bjarmasonn's idea and suggestion, this commit makes modifications in terms of the original discussion on community [1]. In [1] there was a "GIT_TEST_LS_TREE_FORMAT_BACKEND" variable to ensure that we had test coverage for passing tests that would otherwise use show_tree() through show_tree_fmt(), and thus that the formatting mechanism could handle all the same cases as the non-formatting options. Somewhere in subsequent re-rolls of that we seem to have drifted away from what the goal of these tests should be. We're trying to ensure correctness of show_tree_fmt(). We can't tell if we "hit [the] fast-path" here, and instead of having an explicit test for that, we can just add it to something our "test_ls_tree_format" tests for. Here is the statistics about performance tests: 1. Default format (hitten the builtin formats): "git ls-tree <tree-ish>" vs "--format='%(mode) %(type) %(object)%x09%(file)'" $hyperfine --warmup=10 "/opt/git/master/bin/git ls-tree -r HEAD" Benchmark 1: /opt/git/master/bin/git ls-tree -r HEAD Time (mean ± σ): 105.2 ms ± 3.3 ms [User: 84.3 ms, System: 20.8 ms] Range (min … max): 99.2 ms … 113.2 ms 28 runs $hyperfine --warmup=10 "/opt/git/ls-tree-oid-only/bin/git ls-tree -r --format='%(mode) %(type) %(object)%x09%(file)' HEAD" Benchmark 1: /opt/git/ls-tree-oid-only/bin/git ls-tree -r --format='%(mode) %(type) %(object)%x09%(file)' HEAD Time (mean ± σ): 106.4 ms ± 2.7 ms [User: 86.1 ms, System: 20.2 ms] Range (min … max): 100.2 ms … 110.5 ms 29 runs 2.

2022-03-23ls-tree: slightly refactor `show_tree()`Libravatar Teng Long1-37/+61
This is a non-functional change, we introduce an enum "ls_tree_cmdmode" then use it to mark which columns to output. This has the advantage of making the show_tree logic simpler and more readable, as well as making it easier to extend new options (for example, if we want to add a "--object-only" option, we just need to add a similar "short-circuit logic in "show_tree()").

2021-11-11object-file: free(*contents) only in read_loose_object() callerLibravatar Ævar Arnfjörð Bjarmason1-1/+2
In the preceding commit a free() of uninitialized memory regression in 96e41f58fe1 (fsck: report invalid object type-path combinations, 2021-10-01) was fixed, but we'd still have an issue with leaking memory from fsck_loose(). Let's fix that issue too. That issue was introduced in my 31deb28f5e0 (fsck: don't hard die on invalid object types, 2021-10-01). It can be reproduced under SANITIZE=leak with the test I added in 093fffdfbec (fsck tests: add test for fsck-ing an unknown type, 2021-10-01): ./t1450-fsck.sh --run=84 -vixd In some sense it's not a problem, we lost the same amount of memory in terms of things malloc'd and not free'd. It just moved from the "still reachable" to "definitely lost" column in valgrind(1) nomenclature[1], since we'd have die()'d before. But now that we don't hard die() anymore in the library let's properly free() it. Doing so makes this code much easier to follow, since we'll now have one function owning the freeing of the "contents" variable, not two. For context on that memory management pattern the read_loose_object() function was added in f6371f92104 (sha1_file: add read_loose_object() function, 2017-01-13) and subsequently used in c68b489e564 (fsck: parse loose object paths directly, 2017-01-13). The pattern of it being the task of both sides to free() the memory has been there in this form since its inception. 1. https://valgrind.org/docs/manual/mc-manual.html#mc-manual.leaks Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-11-10maintenance: disable cron on macOSLibravatar Derrick Stolee1-6/+21
In eba1ba9 (maintenance: `git maintenance run` learned `--scheduler=<scheduler>`, 2021-09-04), we introduced the ability to specify a scheduler explicitly. This led to some extra checks around whether an alternative scheduler was available. This added the functionality of removing background maintenance from schedulers other than the one selected. On macOS, cron is technically available, but running 'crontab' triggers a UI prompt asking for special permissions. This is the major reason why launchctl is used as the default scheduler. The is_crontab_available() method triggers this UI prompt, causing user disruption. Remove this disruption by using an #ifdef to prevent running crontab this way on macOS. This has the unfortunate downside that if a user manually selects cron via the '--scheduler' option, then adjusting the scheduler later will not remove the schedule from cron. The '--scheduler' option ignores the is_available checks, which is how we can get into this situation. Extract the new check_crontab_process() method to avoid making the 'child' variable unused on macOS. The method is marked MAYBE_UNUSED because it has no callers on macOS.

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.

A refactoring[1] done as part of the recent conversion of 'git submodule add' to builtin, changed the error message shown when a Git directory already exists locally for a submodule name. Before the refactoring, the error used to appear like so: --- START OF OUTPUT --- $ git submodule add ../sub/ subm A git directory for 'subm' is found locally with remote(s): origin /me/git-repos-for-test/sub If you want to reuse this local git directory instead of cloning again from /me/git-repos-for-test/sub use the '--force' option. If the local git directory is not the correct repo or you are unsure what this means choose another name with the '--name' option. --- END OF OUTPUT --- After the refactoring the error started appearing like so: --- START OF OUTPUT --- $ git submodule add ../sub/ subm A git directory for 'subm' is found locally with remote(s): origin /me/git-repos-for-test/sub fatal: If you want to reuse this local git directory instead of cloning again from /me/git-repos-for-test/sub use the '--force' option. If the local git directory is not the correct repo or if you are unsure what this means, choose another name with the '--name' option. --- END OF OUTPUT --- As one could observe the remote information is printed along with the first line rather than on its own line. Also, there's an additional newline following output. Make the error message consistent with the error message that used to be printed before the refactoring. This also moves the 'fatal:' prefix that appears in the middle of the error message to the first line as it would more appropriate to have it in the first line. The output after the change would look like: --- START OF OUTPUT --- $ git submodule add ../sub/ subm fatal: A git directory for 'subm' is found locally with remote(s): origin /me/git-repos-for-test/sub If you want to reuse this local git directory instead of cloning again from /me/git-repos-for-test/sub use the '--force' option.

2021-10-23grep: fix a "path_list" memory leakLibravatar Ævar Arnfjörð Bjarmason1-4/+5
Free the "path_list" used in builtin/grep.c, it was declared as STRING_LIST_INIT_NODUP, let's change it to a STRING_LIST_INIT_DUP since an early user in cmd_grep() appends a string passed via parse-options.c to it, which needs to be duplicated. Let's then convert the remaining callers to use string_list_append_nodup() instead, allowing us to free the list. This makes all the tests in t7811-grep-open.sh pass, 6/10 would fail before this change. The only remaining failure would have been due to a stray "git checkout" (which still leaks memory). In this case we can use a "git reset --hard" instead, so let's do that, and move the test_when_finished() above the code that would modify the relevant file.

Stylistically fix up code added in bfac23d9534 (grep: Fix two memory leaks, 2010-01-30). We usually don't use the "arg" at all once we've casted it to the struct we want, let's not do that here when we're freeing it.

2021-10-20branch: use ref_sorting_release()Libravatar Ævar Arnfjörð Bjarmason1-3/+5
Use a ref_sorting_release() in branch.c to free the memory from the ref_sorting_options(). This plugs the final in-tree memory leak of that API. In the preceding commit the "sorting" variable was left in the cmd_branch() scope, even though that wasn't needed anymore. Move it to the "else if (list)" scope instead. We can also move the "struct string_list" only used for that branch to be declared in that block That "struct ref_sorting" does not need to be "static" (and isn't re-used). The "ref_sorting_options()" will return a valid one, we don't need to make it "static" to have it zero'd out. That it was static was another artifact of the pre-image of the preceding commit.

Change cmd_tag() to free its "struct strbuf"'s instead of using an UNLEAK() pattern. This changes code added in 886e1084d78 (builtin/: add UNLEAKs, 2017-10-01). As shown in the context of the declaration of the "struct msg_arg" (which I'm changing to use a designated initializer while at it, and to show the context in this change), that struct is just a thin wrapper around an int and "struct strbuf".

2021-10-18send-pack: complain about "expecting report" with --helper-statusLibravatar Jeff King1-0/+4
When pushing to a server which erroneously omits the final ref-status report, the client side should complain about the refs for which we didn't receive the status (because we can't just assume they were updated). This works over most transports like ssh, but for http we'll print a very misleading "Everything up-to-date". It works for ssh because send-pack internally sets the status of each ref to REF_STATUS_EXPECTING_REPORT, and then if the server doesn't tell us about a particular ref, it will stay at that value. When we print the final status table, we'll see that we're still on EXPECTING_REPORT and complain then. But for http, we go through remote-curl, which invokes send-pack with "--stateless-rpc --helper-status". The latter option causes send-pack to return a machine-readable list of ref statuses to the remote helper. But ever since its inception in de1a2fdd38 (Smart push over HTTP: client side, 2009-10-30), the send-pack code has simply omitted mention of any ref which ended up in EXPECTING_REPORT. In the remote helper, we then take the absence of any status report from send-pack to mean that the ref was not even something we tried to send, and thus it prints "Everything up-to-date". Fortunately it does detect the eventual non-zero exit from send-pack, and propagates that in its own non-zero exit code. So at least a careful script invoking "git push" would notice the failure. But sending the misleading message on stderr is certainly confusing for humans (not to mention the machine-readable "push --porcelain" output, though again, any careful script should be checking the exit code from push, too). Nobody seems to have noticed because the server in this instance has to be misbehaving: it has promised to support the ref-status capability (otherwise the client will not set EXPECTING_REPORT at all), but didn't send us any. If the connection were simply cut, then send-pack would complain about getting EOF while trying to read the status. But if the server actually sends a flush packet (i.e., saying "now you have all of the ref statuses" without actually sending any), then the client ends up in this confused situation. The fix is simple: we should return an error message from "send-pack --helper-status", just like we would for any other error per-ref error condition (in the test I included, the server simply omits all ref status responses, but a more insidious version of this would skip only some of them).
