* global: mark code units that generate warnings with `-Wsign-compare`Patrick Steinhardt2024-12-061-0/+1
| | | | | | | | | Mark code units that generate warnings with `-Wsign-compare`. This allows for a structured approach to get rid of all such warnings over time in a way that can be easily measured. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* environment: make `get_object_directory()` accept a repositoryPatrick Steinhardt2024-09-121-2/+2
| | | | | | | | | | | The `get_object_directory()` function retrieves the path to the object directory for `the_repository`. Make it accept a `struct repository` such that it can work on arbitrary repositories and make it part of the repository subsystem. This reduces our reliance on `the_repository` and clarifies scope.

| * global: introduce `USE_THE_REPOSITORY_VARIABLE` macroPatrick Steinhardt2024-06-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of the `the_repository` variable is deprecated nowadays, and we slowly but steadily convert the codebase to not use it anymore. Instead, callers should be passing down the repository to work on via parameters. It is hard though to prove that a given code unit does not use this variable anymore. The most trivial case, merely demonstrating that there is no direct use of `the_repository`, is already a bit of a pain during code reviews as the reviewer needs to manually verify claims made by the patch author. The bigger problem though is that we have many interfaces that implicitly rely on `the_repository`. Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code units to opt into usage of `the_repository`. The intent of this macro is to demonstrate that a certain code unit does not use this variable anymore, and to keep it from new dependencies on it in future changes, be it explicit or implicit For now, the macro only guards `the_repository` itself as well as `the_hash_algo`. There are many more known interfaces where we have an implicit dependency on `the_repository`, but those are not guarded at the current point in time. Over time though, we should start to add guards as required (or even better, just remove them). Define the macro as required in our code units. As expected, most of our code still relies on the global variable. Nearly all of our builtins rely on the variable as there is no way yet to pass `the_repository` to their entry point. For now, declare the macro in "biultin.h" to keep the required changes at least a little bit more contained.

* | server-info.c: remove temporary info files on exitTaylor Blau2024-06-071-16/+10
|/ | | | | | | | | | | | | | | | | | | | | | The update_info_file() function within server-info.c is responsible for moving the info/refs and info/packs files around when updating server info. These updates are staged into a temporary file and then moved into place atomically to avoid race conditions when reading those files. However, the temporary file used to stage these changes is managed outside of the tempfile.h API, and thus survives process death. Manage these files instead with the tempfile.h API so that they are automatically cleaned up upon abnormal process death. Unfortunately, and unlike in the previous step, there isn't a straightforward way to inject a failure into the update-server-info step that causes us to die() rather than take the cleanup path in label 'out', hence the lack of a test here.

Make that change now.

* git-compat-util.h: use "UNUSED", not "UNUSED(var)"Ævar Arnfjörð Bjarmason2022-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | As reported in [1] the "UNUSED(var)" macro introduced in 2174b8c75de (Merge branch 'jk/unused-annotation' into next, 2022-08-24) breaks coccinelle's parsing of our sources in files where it occurs. Let's instead partially go with the approach suggested in [2] of making this not take an argument. As noted in [1] "coccinelle" will ignore such tokens in argument lists that it doesn't know about, and it's less of a surprise to syntax highlighters. This undoes the "help us notice when a parameter marked as unused is actually use" part of 9b240347543 (git-compat-util: add UNUSED macro, 2022-08-19), a subsequent commit will further tweak the macro to implement a replacement for that functionality. 1. https://lore.kernel.org/git/220825.86ilmg4mil.gmgdl@evledraar.gmail.com/ 2. https://lore.kernel.org/git/220819.868rnk54ju.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This is intended to preserve mtime and make it easier for dumb HTTP pollers to rely on the If-Modified-Since header. Combined with stdio and kernel buffering; the kernel should be able to avoid block layer writes and reduce wear for small files. As a result, the --force option is no longer needed.

* server-info: drop objdirlen pointer arithmeticJeff King2019-04-161-8/+2
| | | | | | | | | | | | | | | | | | | | | When writing objects/info/packs, we use the basename of each pack (i.e., just the "pack-1234abcd.pack" part). We compute that manually by adding "objdirlen + 6" to the name. This _should_ work consistently, as we do not include non-local packs, meaning everything should be in $objdir/pack/. Before f13d7db4af (server-info.c: use pack_local like everybody else., 2005-12-05), this was definitely true, since we computed "local" based on comparing the objdir string. Since then, we're relying on the code on packfile.c to match our expectations of p->pack_name and p->local. I think our expectations do still hold today, but we can be a bit more defensive by just using pack_basename() to get the base. That future-proofs us, and should hopefully be more obviously safe to somebody reading the code. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* server-info: drop nr_alloc struct memberJeff King2019-04-161-1/+1
| | | | | | | | | | | | | | | | We keep an array of struct pointers, with each one representing a single packfile. But for some reason there is a nr_alloc parameter inside each struct, which has never been used. This is probably cruft left over from development, where we might have wanted a nr_alloc to dynamically grow the list. But as it turns out, we do not dynamically grow the list at all, but rather count up the total number of packs and use that as a maximum size. So while we're thinking of this, let's add an assert() that documents (and checks!) that our allocation and fill loops stay in sync.

* server-info: use strbuf to read old info/packs fileJeff King2019-04-161-10/+8
| | | | | | | | | | | | | | | This old code uses fgets with a fixed-size buffer. Let's use a strbuf instead, so we don't have to wonder if "1000" is big enough, or what happens if we see a long line. This also lets us drop our custom code to trim the newline. Probably nobody actually cares about the 1000-char limit (after all, the lines generally only say "P pack-[0-9a-f]{40}.pack"), so this is mostly just about cleanup/readability.

* server-info: simplify cleanup in parse_pack_def()Jeff King2019-04-161-3/+4
| | | | | | | | | | We have two exits from the function: either we jump to the out_stale label or not. But in both exits we repeat our cleanup, and the only difference is our return value. Let's just use a variable for the return value to avoid repeating ourselves. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* server-info: fix blind pointer arithmeticJeff King2019-04-161-10/+12
| | | | | | | | | | | | | | | | | | | | | | When we're writing out a new objects/info/packs file, we read back the old one to try to keep the ordering the same. When we see a line starting with "P", we expect "P pack-1234..." and blindly jump to "line + 2" to parse the pack name. If we saw a line with _just_ "P" and nothing else, we'd jump past the end of the buffer and start reading arbitrary memory. This shouldn't be a big attack vector, as the files are local to the repository and written by us, but it's clearly worth fixing (we do read remote copies of the file for dumb-http fetches, but using a totally different parser!). Let's instead use skip_prefix() here, which avoids pointer arithmetic altogether. Note that this converts our switch statement to an if/else chain, making it slightly more verbose. But it will also make it easier to do a few follow-on cleanups. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* Convert struct object to object_idbrian m. carlson2015-11-201-1/+1
| | | | | | | | | struct object is one of the major data structures dealing with object IDs. Convert it to use struct object_id instead of an unsigned char array. Convert get_object_hash to refer to the new member as well. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Jeff King <peff@peff.net>

* each_ref_fn: change to take an object_id parameterMichael Haggerty2015-05-251-1/+4
| | | | | | | | | | | | | | | | | | | | | Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

* update-server-info: create info/* with mode 0666Jeff King2015-01-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Prior to d38379e (make update-server-info more robust, 2014-09-13), we used a straight "fopen" to create the info/refs and objects/info/packs files, which creates the file using mode 0666 (less the default umask). In d38379e, we switched to creating the file with mkstemp to get a unique filename. But mkstemp also uses the more restrictive 0600 mode to create the file. This was an unintended side effect that we did not want, and causes problems when the repository is served by a different user than the one running update-server-info (it is not readable by a dumb http server running as `www`, for example). We can fix this by using git_mkstemp_mode and specifying 0666 to make sure that the umask is honored. Note that we could also say "just use core.sharedrepository", as we do call adjust_shared_perm on the result before renaming it into place. But that should not be necessary as long as everybody involved is using permissive umask to allow HTTP server to read necessary files.
