The purpose of "git init --separate-git-dir" is to initialize a new project with the repository separate from the working tree, or, in the case of an existing project, to move the repository (the .git/ directory) out of the working tree. It does not make sense to use --separate-git-dir with a bare repository for which there is no working tree, so disallow its use with bare repositories. * es/init-no-separate-git-dir-in-bare: init: disallow --separate-git-dir with bare repository
2020-08-22checkout, restore: make pathspec recursiveLibravatar René Scharfe1-0/+2
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.

2020-08-21index-pack: adjust default threading capLibravatar Jeff King1-3/+16
Commit b8a2486f15 (index-pack: support multithreaded delta resolving, 2012-05-06) describes an experiment that shows that setting the number of threads for index-pack higher than 3 does not help. I repeated that experiment using a more modern version of Git and a more modern CPU and got different results. Here are timings for p5302 against linux.git run on my laptop, a Core i9-9880H with 8 cores plus hyperthreading (so online-cpus returns 16): 5302.3: index-pack 0 threads 256.28(253.41+2.79) 5302.4: index-pack 1 threads 257.03(254.03+2.91) 5302.5: index-pack 2 threads 149.39(268.34+3.06) 5302.6: index-pack 4 threads 94.96(294.10+3.23) 5302.7: index-pack 8 threads 68.12(339.26+3.89) 5302.8: index-pack 16 threads 70.90(655.03+7.21) 5302.9: index-pack default number of threads 116.91(290.05+3.21) You can see that wall-clock times continue to improve dramatically up to the number of cores, but bumping beyond that (into hyperthreading territory) does not help (and in fact hurts a little). Here's the same experiment on a machine with dual Xeon 6230's, totaling 40 cores (80 with hyperthreading): 5302.3: index-pack 0 threads 310.04(302.73+6.90) 5302.4: index-pack 1 threads 310.55(302.68+7.40) 5302.5: index-pack 2 threads 178.17(304.89+8.20) 5302.6: index-pack 5 threads 99.53(315.54+9.56) 5302.7: index-pack 10 threads 72.80(327.37+12.79) 5302.8: index-pack 20 threads 60.68(357.74+21.66) 5302.9: index-pack 40 threads 58.07(454.44+67.96) 5302.10: index-pack 80 threads 59.81(720.45+334.52) 5302.11: index-pack default number of threads 134.18(309.32+7.98) The results are similar; things stop improving at 40 threads. Curiously, going from 20 to 40 really doesn't help much, either (and increases CPU time considerably). So that may represent an actual barrier to parallelism, where we lose out due to context-switching and loss of cache locality, but don't reap the wall-clock benefits due to contention of our coarse-grained locks. So what's a good default value? It's clear that the current cap of 3 is too low; our default values are 42% and 57% slower than the best times on each machine. The results on the 40-core machine imply that 20 threads is an actual barrier regardless of the number of cores, so we'll take that as a maximum. We get the best results on these machines at half of the online-cpus value. That's presumably a result of the hyperthreading. That's common on multi-core Intel processors, but not necessarily elsewhere. But if we take it as an assumption, we can perform optimally on hyperthreaded machines and still do much better than the status quo on other machines, as long as we never half below the current value of 3. So that's what this patch does. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-08-18dir: fix problematic API to avoid memory leaksLibravatar Elijah Newren6-13/+14
The dir structure seemed to have a number of leaks and problems around it. First I noticed that parent_hashmap and recursive_hashmap were being leaked (though Peff noticed and submitted fixes before me). Then I noticed in the previous commit that clear_directory() was only taking responsibility for a subset of fields within dir_struct, despite the fact that entries[] and ignored[] we allocated internally to dir.c. That, of course, resulted in many callers either leaking or haphazardly trying to free these arrays and their contents. Digging further, I found that despite the pretty clear documentation near the top of dir.h that folks were supposed to call clear_directory() when the user no longer needed the dir_struct, there were four callers that didn't bother doing that at all. However, two of them clearly thought about leaks since they had an UNLEAK(dir) directive, which to me suggests that the method to free the data was too unclear. I suspect the non-obviousness of the API and its holes led folks to avoid it, which then snowballed into further problems with the entries[], ignored[], parent_hashmap, and recursive_hashmap problems. Rename clear_directory() to dir_clear() to be more in line with other data structures in git, and introduce a dir_init() to handle the suggested memsetting of dir_struct to all zeroes. I hope that a name like "dir_clear()" is more clear, and that the presence of dir_init() will provide a hint to those looking at the code that they need to look for either a dir_clear() or a dir_free() and lead them to find dir_clear().

2020-08-18dir: make clear_directory() free all relevant memoryLibravatar Elijah Newren2-8/+1
The calling convention for the dir API is supposed to end with a call to clear_directory() to free up no longer needed memory. However, clear_directory() didn't free dir->entries or dir->ignored. I believe this was an oversight, but a number of callers noticed memory leaks and started free'ing these. Unfortunately, they did so somewhat haphazardly (sometimes freeing the entries in the arrays, and sometimes only free'ing the arrays themselves). This suggests the callers weren't trying to make sure any possible memory used might be free'd, but just the memory they noticed their usecase definitely had allocated. Fix this mess by moving all the duplicated free'ing logic into clear_directory(). End by resetting dir to a pristine state so it could be reused if desired.

2020-08-18fetch: optionally allow disabling FETCH_HEAD updateLibravatar Junio C Hamano1-3/+12
If you run fetch but record the result in remote-tracking branches, and either if you do nothing with the fetched refs (e.g. you are merely mirroring) or if you always work from the remote-tracking refs (e.g. you fetch and then merge origin/branchname separately), you can get away with having no FETCH_HEAD at all. Teach "git fetch" a command line option "--[no-]write-fetch-head". The default is to write FETCH_HEAD, and the option is primarily meant to be used with the "--no-" prefix to override this default, because there is no matching fetch.writeFetchHEAD configuration variable to flip the default to off (in which case, the positive form may become necessary to defeat it). Note that under "--dry-run" mode, FETCH_HEAD is never written; otherwise you'd see list of objects in the file that you do not actually have. Passing `--write-fetch-head` does not force `git fetch` to write the file. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-08-17submodule--helper: fix leak of core.worktree valueLibravatar Jeff King1-2/+2
In the ensure_core_worktree() function, we load the core.worktree value of the submodule repository using repo_config_get_string(). This function copies the string, but we never free it, leaking the memory. We can instead use the "tmp" version of that function to avoid the allocation at all. We don't have to worry about lifetime issues, since we never even look at the value (we just want to know if it's set).

2020-08-17refspec: make sure stack refspec_item variables are zeroedLibravatar Jacob Keller1-0/+1
A couple of functions that used struct refspec_item did not zero out the structure memory. This can result in unexpected behavior, especially if additional parameters are ever added to refspec_item in the future. Use memset to ensure that unset structure members are zero. It may make sense to convert most of these uses of struct refspec_item to use either struct initializers or refspec_item_init_or_die. However, other similar code uses memset. Converting all of these uses has been left as a future exercise. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-08-14config: fix leaks from git_config_get_string_const()Libravatar Jeff King2-5/+5
There are two functions to get a single config string: - git_config_get_string() - git_config_get_string_const() One might naively think that the first one allocates a new string and the second one just points us to the internal configset storage. But in fact they both allocate a new copy; the second one exists only to avoid having to cast when using it with a const global which we never intend to free. The documentation for the function explains that clearly, but it seems I'm not alone in being surprised by this. Of 17 calls to the function, 13 of them leak the resulting value. We could obviously fix these by adding the appropriate free(). But it would be simpler still if we actually had a non-allocating way to get the string. There's git_config_get_value() but that doesn't quite do what we want. If the config key is present but is a boolean with no value (e.g., "[foo]bar" in the file), then we'll get NULL (whereas the string versions will print an error and die). So let's introduce a new variant, git_config_get_string_tmp(), that behaves as these callers expect. We need a new name because we have new semantics but the same function signature (so even if we converted the four remaining callers, topics in flight might be surprised). The "tmp" is because this value should only be held onto for a short time. In practice it's rare for us to clear and refresh the configset, invalidating the pointer, but hopefully the "tmp" makes callers think about the lifetime. In each of the converted cases here the value only needs to last within the local function or its immediate caller.

2020-08-14submodule--helper: use strbuf_release() to free strbufsLibravatar Jeff King1-2/+2
The prepare_to_clone_next_submodule() function has a few local-variable strbufs. We use strbuf_reset() throughout the function to reuse the buffers over and over. But at the end of the function we also use strbuf_reset() as they go out of scope, which means we end up leaking their heap buffers. This should be strbuf_release() instead. These were introduced by 48308681b0 (git submodule update: have a dedicated helper for cloning, 2016-02-29), but it doesn't seem to have the same mistake elsewhere.

We UNLEAK() the "sorting" list created by parsing command-line options (which is essentially used until the program exits). But we do so right before leaving the cmd_ls_remote() function, which means we have to hit all of the exits. But the point of UNLEAK() is that it's an annotation which doesn't impact the variable itself. We can mark it as soon as we're done writing its value, and then we only have to do so once.

2020-08-10init: disallow --separate-git-dir with bare repositoryLibravatar Eric Sunshine1-0/+5
The purpose of "git init --separate-git-dir" is to separate the repository from the worktree. This is true even when --separate-git-dir is used on an existing worktree, in which case, it moves the .git/ subdirectory to a new location outside the worktree. However, an outright bare repository (such as one created by "git init --bare"), has no worktree, so using --separate-git-dir to separate it from its non-existent worktree is nonsensical. Therefore, make it an error to use --separate-git-dir on a bare repository. Implementation note: "git init" considers a repository bare if told so explicitly via --bare or if it guesses it to be so based upon heuristics. In the explicit --bare case, a conflict with --separate-git-dir is easy to detect early. In the guessed case, however, the conflict can only be detected once "bareness" is guessed, which happens after "git init" has begun creating the repository. Technically, we can get by with a single late check which would cover both cases, however, erroring out early, when possible, without leaving detritus provides a better user experience.

cmd_bisect__helper() is intended as a temporary shim layer serving as an interface for git-bisect.sh. This function and git-bisect.sh should eventually be replaced by a C implementation, cmd_bisect(), serving as an entrypoint for all "git bisect ..." shell commands: cmd_bisect() will only parse the first token following "git bisect", and dispatch the remaining args to the appropriate function ["bisect_start()", "bisect_next()", etc.]. Thus, cmd_bisect__helper() should not be responsible for parsing flags like --no-checkout. Instead, let the --no-checkout flag remain in the argv array, so it may be evaluated alongside the other options already parsed by bisect_start().

While packing many objects in a repository with a promissor remote, lazily fetching missing objects from the promissor remote one by one may be inefficient---the code now attempts to fetch all the missing objects in batch (obviously this won't work for a lazy clone that lazily fetches tree objects as you cannot even enumerate what blobs are missing until you learn which trees are missing). * jt/pack-objects-prefetch-in-batch: pack-objects: prefetch objects to be packed pack-objects: refactor to oid_object_info_extended

2020-08-03merge: make merge.renormalize work for all uses of merge machineryLibravatar Elijah Newren2-11/+0
The 'merge' command is not the only one that does merges; other commands like checkout -m or rebase do as well. Unfortunately, the only area of the code that checked for the "merge.renormalize" config setting was in builtin/merge.c, meaning it could only affect merges performed by the "merge" command. Move the handling of this config setting to merge_recursive_config() so that other commands can benefit from it as well. Fixes a few tests in t6038.

2020-07-30strvec: rename struct fieldsLibravatar Jeff King21-77/+77
The "argc" and "argv" names made sense when the struct was argv_array, but now they're just confusing. Let's rename them to "nr" (which we use for counts elsewhere) and "v" (which is rather terse, but reads well when combined with typical variable names like "args.v"). Note that we have to update all of the callers immediately. Playing tricks with the preprocessor is hard here, because we wouldn't want to rewrite unrelated tokens.

2020-07-30repository: enable SHA-256 support by defaultLibravatar brian m. carlson1-5/+0
Now that we have a complete SHA-256 implementation in Git, let's enable it so people can use it. Remove the ENABLE_SHA256 define constant everywhere it's used. Add tests for initializing a repository with SHA-256.

2020-07-30bundle: add new version for use with SHA-256Libravatar brian m. carlson1-1/+4
Currently we detect the hash algorithm in use by the length of the object ID. This is inelegant and prevents us from using a different hash algorithm that is also 256 bits in length. Since we cannot extend the v2 format in a backward-compatible way, let's add a v3 format, which is identical, except for the addition of capabilities, which are prefixed by an at sign. We add "object-format" as the only capability and reject unknown capabilities, since we do not have a network connection and therefore cannot negotiate with the other side. For compatibility, default to the v2 format for SHA-1 and require v3 for SHA-256. In t5510, always use format v3 so we can be sure we produce consistent results across hash algorithms. Since head -n N lists the top N lines instead of the Nth line, let's run our output through sed to normalize it and compare it against a fixed value, which will make sure we get exactly what we're expecting.
