| | | | | | | | | | | | | | | | | | | | | | | | Extract the read_index_data() function from attr.c and move it to read-cache.c; rename it to read_blob_data_from_index() and update the function signature of it to align better with index/cache API functions. This allows for reusing the function in convert.c later. Signed-off-by: Lukas Fleischer <git@cryptocrack.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * | name-hash.c: fix endless loop with core.ignorecase=trueKarsten Blees2013-02-27

Currently, the existing cache entry structures are added multiple times to the same hashtable (with different name lengths and hash codes). However, there's only one dir_next pointer, which gets completely messed up in case of hash collisions. In the worst case, this causes an endless loop if ce == ce->dir_next (see t7062). Use a separate hashtable and separate structures for the directory index so that each directory entry has its own next pointer. Use reference counting to track which directory entry contains files. There are only slight changes to the name-hash.c API: - new free_name_hash() used by read_cache.c::discard_index() - remove_name_hash() takes an additional index_state parameter - index_name_exists() for a directory (trailing '/') may return a cache entry that has been removed (CE_UNHASHED). This is not a problem as the return value is only used to check if the directory exists (dir.c) or to normalize casing of directory names (read-cache.c). Getting rid of cache_entry.dir_next reduces memory consumption, especially with core.ignorecase=false (which doesn't use that member at all). With core.ignorecase=true, building the directory index is slightly faster as we add / check the parent directory first (instead of going through all directory levels for each file in the index). E.g. with WebKit (~200k files, ~7k dirs), time spent in lazy_init_name_hash is reduced from 176ms to 130ms.

* | Enable minimal stat checkingRobin Rosenberg2013-01-22
|/ | | | | | | | | | | | | | | | | | | Specifically the fields uid, gid, ctime, ino and dev are set to zero by JGit. Other implementations, eg. Git in cygwin are allegedly also somewhat incompatible with Git For Windows and on *nix platforms the resolution of the timestamps may differ. Any stat checking by git will then need to check content, which may be very slow, particularly on Windows. Since mtime and size is typically enough we should allow the user to tell git to avoid checking these fields if they are set to zero in the index. This change introduces a core.checkstat config option where the the user can select to check all fields (default), or just size and the whole second part of mtime (minimal).

If we attempt to do so, it is much more likely that it is a bug, since we use the null sha1 as a sentinel value to mean "not valid". The presence of null sha1s in the index (which can come from, among other things, "update-index --cacheinfo", or by reading a corrupted tree) can cause problems for later readers, because they cannot distinguish the literal null sha1 from its use a sentinel value. For example, "git diff-files" on such an entry would make it appear as if it is stat-dirty, and until recently, the diff code assumed such an entry meant that we should be diffing a working tree file rather than a blob. Ideally, we would stop such entries from entering even our in-core index. However, we do sometimes legitimately add entries with null sha1s in order to represent these sentinel situations; simply forbidding them in add_index_entry breaks a lot of the existing code. However, we can at least make sure that our in-core sentinel representation never makes it to disk. To be thorough, we will test an attempt to add both a blob and a submodule entry. In the former case, we might run into problems anyway because we will be missing the blob object. But in the latter case, we do not enforce connectivity across gitlink entries, making this our only point of enforcement. The current implementation does not care which type of entry we are seeing, but testing both cases helps future-proof the test suite in case that changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These assignments comes from the very first commit e83c516 (Initial revision of "git", the information manager from hell - 2005-04-07). Back then we did not die() when errors happened so correct errno was required. Since 5d1a5c0 ([PATCH] Better error reporting for "git status" - 2005-10-01), read_index_from() learned to die rather than just return -1 and these assignments became irrelevant. Remove them. While at it, move die_errno() next to xmmap() call because it's the mmap's error code that we care about. Otherwise if close(fd); fails, it could overwrite mmap's errno.

It also makes CE_NAMEMASK private, so that users don't mistakenly write the name length in the flags.

It does that by using the file size, the number of entries and the difference of the sizes of the on-disk and in-memory structs -- without having to check the length of the name of each entry, which varies for each entry, but their sums are the same no matter the representation. Except there can be a difference. First of all, the size is really calculated by ce_size and ondisk_ce_size based on offsetof(..., name), not sizeof, which can be different. And entries are padded with 1 to 8 NULs at the end (after the variable name) to make their total length a multiple of eight. So in order to allocate enough memory to hold the index, change the delta calculation to be based on offsetof(..., name) and round up to the next multiple of eight. On a 32-bit Linux, this delta was used before: sizeof(struct cache_entry) == 72 sizeof(struct ondisk_cache_entry) == 64 --- 8 The actual difference for an entry with a filename length of one was, however (find the definitions are in cache.h): offsetof(struct cache_entry, name) == 72 offsetof(struct ondisk_cache_entry, name) == 62 ce_size == (72 + 1 + 8) & ~7 == 80 ondisk_ce_size == (62 + 1 + 8) & ~7 == 64 --- 16 So eight bytes less had been allocated for such entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "format_check" parameter tucked after the existing parameters is too ugly an afterthought to live in any reasonable API. Combine it with the other boolean parameter "write_object" into a single "flags" parameter. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * | | update $GIT_INDEX_FILE when there are racily clean entriesJunio C Hamano2011-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditional "opportunistic index update" done by read-only "diff" and "status" was about updating cached lstat(2) information in the index for the next round. We missed another obvious optimization opportunity: when there are racily clean entries that will cease to be racily clean by updating $GIT_INDEX_FILE. Detect that case and write $GIT_INDEX_FILE out to give it a newer timestamp. Noticed by Lasse Makholm by stracing "git status" in a fresh checkout and counting the number of open(2) calls.

| * | | diff/status: refactor opportunistic index updateJunio C Hamano2011-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we had to refresh the index internally before running diff or status, we opportunistically updated the $GIT_INDEX_FILE so that later invocation of git can use the lstat(2) we already did in this invocation. Make them share a helper function to do so. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commits, trees and tags have structure. Don't let users feed git with malformed ones. Sooner or later git will die() when encountering them. Note that this patch does not check semantics. A tree that points to non-existent objects is perfectly OK (and should be so, users may choose to add commit first, then its associated tree for example).
