* | update-server-info: avoid needless overwritesEric Wong2019-05-151-24/+116
|/ | | | | | | | | | | | | | | | | | | | Do not change the existing info/refs and objects/info/packs files if they match the existing content on the filesystem. 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. So stop documenting it, but let it remain for compatibility (and debugging, if necessary). v3: perform incremental comparison while generating to avoid OOM with giant files.

* 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>

| | | | | | | | | | | | | | | | | | | | | 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 0666jk/prune-packed-server-infoJeff 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since "git update-server-info" may be called automatically as part of a push or a "gc --auto", we should be robust against two processes trying to update it simultaneously. However, we currently use a fixed tempfile, which means that two simultaneous writers may step on each other's toes and end up renaming junk into place. Let's instead switch to using a unique tempfile via mkstemp. We do not want to use a lockfile here, because it's OK for two writers to simultaneously update (one will "win" the rename race, but that's OK; they should be writing the same information). While we're there, let's clean up a few other things: 1. Detect write errors. Report them and abort the update if any are found. 2. Free path memory rather than leaking it (and clean up the tempfile when necessary). 3. Use the pathdup functions consistently rather than static buffers or manually calculated lengths. This last one fixes a potential overflow of "infofile" in update_info_packs (e.g., by putting large junk into $GIT_OBJECT_DIRECTORY). However, this overflow was probably not an interesting attack vector for two reasons: a. The attacker would need to control the environment to do this, in which case it was already game-over. b. During its setup phase, git checks that the directory actually exists, which means it is probably shorter than PATH_MAX anyway. Because both update_info_refs and update_info_packs share these same failings (and largely duplicate each other), this patch factors out the improved error-checking version into a helper function.

| | | | | | | | | | | | | | | This updates the type-enumeration constants introduced to reduce the memory footprint of "struct object" to match the type bits already used in the packfile format, by removing the former (i.e. TYPE_* constant macros) and using the latter (i.e. enum object_type) throughout the code for consistency. Eventually we can stop passing around the "type strings" entirely, and this will help - no confusion about two different integer enumeration.

* Shrink "struct object" a bitLinus Torvalds2006-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shrinks "struct object" by a small amount, by getting rid of the "struct type *" pointer and replacing it with a 3-bit bitfield instead. In addition, we merge the bitfields and the "flags" field, which incidentally should also remove a useless 4-byte padding from the object when in 64-bit mode. Now, our "struct object" is still too damn large, but it's now less obviously bloated, and of the remaining fields, only the "util" (which is not used by most things) is clearly something that should be eventually discarded. This shrinks the "git-rev-list --all" memory use by about 2.5% on the kernel archive (and, perhaps more importantly, on the larger mozilla archive). That may not sound like much, but I suspect it's more on a 64-bit platform. There are other remaining inefficiencies (the parent lists, for example, probably have horrible malloc overhead), but this was pretty obvious. Most of the patch is just changing the comparison of the "type" pointer from one of the constant string pointers to the appropriate new TYPE_xxx small integer constant.

* objects/info/packs: work around bug in http-fetch.c::fetch_indices()Junio C Hamano2005-12-211-0/+1
| | | | | | | | | The code to fetch pack index files in deployed clients have a bug that causes it to ignore the pack file on the last line of objects/info/packs file, so append an empty line to work it around. Signed-off-by: Junio C Hamano <junkio@cox.net>
* qsort(): ptrdiff_t may be larger than intJunio C Hamano2005-12-081-1/+6
| | | | | | | | | This is a companion patch to e23eff8be92a2a2cb66b53deef020063cff285ed commit. The same logic, the same rationale that a comparison function that returns an int should not just compute a ptrdiff_t and return it. Signed-off-by: Junio C Hamano <junkio@cox.net>
