The ALLOC_GROW macro will never let us fill the array completely, instead allocating an extra chunk if that would be the case. This is because the 'nr' argument was originally treated as "how much we do have now" instead of "how much do we want". The latter makes much more sense because you can grow by more than one item. This off-by-one never resulted in an error because it meant we were overly conservative about when to allocate. Any callers which passed "how much we have now" need to be updated, or they will fail to allocate enough. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

so that an ugly commit message like this can be handled sanely. Currently, --pretty=oneline and --pretty=email (hence format-patch) take and use only the first line of the commit log message. This changes them to: - Take the first paragraph, where the definition of the first paragraph is "skip all blank lines from the beginning, and then grab everything up to the next empty line". - Replace all line breaks with a whitespace. This change would not affect a well-behaved commit message that adheres to the convention of "single line summary, a blank line, and then body of message", as its first paragraph always consists of a single line. Commit messages from different culture, such as the ones imported from CVS/SVN, can however get chomped with the existing behaviour at the first linebreak in the middle of sentence right now, which would become much easier to see with this change. The Subject: and --pretty=oneline output would become very long and unsightly for non-conforming commits, but their messages are already ugly anyway, and thischange at least avoids the loss of information. The Subject: line from a multi-line paragraph is folded using RFC2822 line folding rules at the places where line breaks were in the original. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

由 Shawn O. Pearce 提交于
In some repository configurations the user may have many packfiles, but all of the recent commits/trees/tags/blobs are likely to be in the most recent packfile (the one with the newest mtime). It is therefore common to be able to complete an entire operation by accessing only one packfile, even if there are 25 packfiles available to the repository. Rather than opening and mmaping the corresponding .idx file for every pack found, we now only open and map the .idx when we suspect there might be an object of interest in there. Of course we cannot known in advance which packfile contains an object, so we still need to scan the entire packed_git list to locate anything. But odds are users want to access objects in the most recently created packfiles first, and that may be all they ever need for the current operation. Junio observed in b867092f that placing recent packfiles before older ones can slightly improve access times for recent objects, without degrading it for historical object access. This change improves upon Junio's observations by trying even harder to avoid the .idx files that we won't need. Signed-off-by: NShawn O.

As noted by Johan Herland, git-archive is a kind of checkout and needs to apply any checkout filters that might be configured. This patch adds the convenience function convert_sha1_file which returns a buffer containing the object's contents, after converting, if necessary (i.e. it's a combination of read_sha1_file and convert_to_working_tree). Direct calls to read_sha1_file in git-archive are then replaced by calls to convert_sha1_file. Since convert_sha1_file expects its path argument to be NUL-terminated -- a convention it inherits from convert_to_working_tree -- the patch also changes the path handling in archive-tar.c to always NUL-terminate the string. It used to solely rely on the len field of struct strbuf before. archive-zip.c already NUL-terminates the path and thus needs no such change.

由 Junio C Hamano 提交于
When we are applying a patch that creates a blob at a path, or when we are switching from a branch that does not have a blob at the path to another branch that has one, we need to make sure that there is nothing at the path in the working tree, as such a file is a local modification made by the user that would be lost by the operation. Normally, lstat() on the path and making sure ENOENT is returned is good enough for that purpose. However there is a twist. We may be creating a regular file arch/x86_64/boot/Makefile, while removing an existing symbolic link at arch/x86_64/boot that points at existing ../i386/boot directory that has Makefile in it. We always first check without touching filesystem and then perform the actual operation, so when we verify the new file, arch/x86_64/boot/Makefile, does not exist, we haven't removed the symbolic link arc/x86_64/boot symbolic link yet. lstat() on the file sees through the symbolic link and reports the file is there, which is not what we want. The function has_symlink_leading_path() function takes a path, and sees if any of the leading directory component is a symbolic link. When files in a new directory are created, we tend to process them together because both index and tree are sorted. The function takes advantage of this and allows the caller to cache and reuse which symbolic link on the filesystem caused the function to return true. The calling sequence would be: char last_symlink[PATH_MAX]; *last_symlink = '\0'; for each index entry { if (!lose) continue; if (lstat(it)) if (errno == ENOENT) ; /* happy */ else error; else if (has_symlink_leading_path(it, last_symlink)) ; /* happy */ else error; /* would lose local changes */ unlink_entry(it, last_symlink); } Signed-off-by: NJunio C Hamano <junkio@cox.net>

Add config variables pack.compression and core.loosecompression , and switch --compression=level to pack-objects. Loose objects will be compressed using core.loosecompression if set, else core.compression if set, else Z_BEST_SPEED. Packed objects will be compressed using --compression=level if seen, else pack.compression if set, else core.compression if set, else Z_DEFAULT_COMPRESSION. This is the "pack compression level". Loose objects added to a pack undeltified will be recompressed to the pack compression level if it is unequal to the current loose compression level by the preceding rules, or if the loose object was written while core.legacyheaders = true. Newly deltified loose objects are always compressed to the current pack compression level. Previously packed objects added to a pack are recompressed to the current pack compression level exactly when their deltification status changes, since the previous pack data cannot be reused. In either case, the --no-reuse-object switch from the first patch below will always force recompression to the current pack compression level, instead of assuming the pack compression level hasn't changed and pack data can be reused when possible. This applies on top of the following patches from Nicolas Pitre: [PATCH] allow for undeltified objects not to be reused [PATCH] make "repack -f" imply "pack-objects --no-reuse-object" Signed-off-by: NDana L.

Now that we encourage and actively preserve objects in a packed form more agressively than we did at the time the new loose object format and core.legacyheaders were introduced, that extra loose object format doesn't appear to be worth it anymore. Because the packing of loose objects has to go through the delta match loop anyway, and since most of them should end up being deltified in most cases, there is really little advantage to have this parallel loose object format as the CPU savings it might provide is rather lost in the noise in the end. This patch gets rid of core.legacyheaders, preserve the legacy format as the only writable loose object format and deprecate the other one to keep things simpler.

The usual process flow is the main process opens and holds the lock to the index, does its thing, perhaps spawning children during the course, and then writes the resulting index out by releaseing the lock. However, the lockfile interface uses atexit(3) to clean it up, without regard to who actually created the lock. This typically leads to a confusing behaviour of lock being released too early when the child exits, and then the parent process when it calls commit_lockfile() finds that it cannot unlock it. This fixes the problem by recording who created and holds the lock, and upon atexit(3) handler, child simply ignores the lockfile the parent created. Signed-off-by: NJunio C Hamano <junkio@cox.net>

We used to use a different allocator scheme for when we didn't know the object type. That meant that objects that were created without any up-front knowledge of the type would not go through the same allocation paths as normal object allocations, and would miss out on the statistics. But perhaps more importantly than the statistics (that are useful when looking at memory usage but not much else), if we want to make the object hash tables use a denser object pointer representation, we need to make sure that they all go through the same blocking allocator.

This adds "attribute macros" (for lack of better name). So far, we have low-level attributes such as crlf and diff, which are defined in operational terms --- setting or unsetting them on a particular path directly affects what is done to the path. For example, in order to decline diffs or crlf conversions on a binary blob, no diffs on PostScript files, and treat all other files normally, you would have something like these: * diff crlf *.ps !diff proprietary.o !diff !crlf That is fine as the operation goes, but gets unwieldy rather rapidly, when we start adding more low-level attributes that are defined in operational terms. A near-term example of such an attribute would be 'merge-3way' which would control if git should attempt the usual 3-way file-level merge internally, or leave merging to a specialized external program of user's choice. When it is added, we do _not_ want to force the users to update the above to: * diff crlf merge-3way *.ps !diff proprietary.o !diff !crlf !merge-3way The way this patch solves this issue is to realize that the attributes the user is assigning to paths are not defined in terms of operations but in terms of what they are. All of the three low-level attributes usually make sense for most of the files that sane SCM users have git operate on (these files are typically called "text'). Only a few cases, such as binary blob, need exception to decline the "usual treatment given to text files" -- and people mark them as "binary". So this allows the $GIT_DIR/info/alternates and .gitattributes at the toplevel of the project to also specify attributes that assigns other attributes. The syntax is '[attr]' followed by an attribute name followed by a list of attribute names: [attr] binary !diff !crlf !merge-3way When "binary" attribute is set to a path, if the path has not got diff/crlf/merge-3way attribute set or unset by other rules, this rule unsets the three low-level attributes. It is expected that the user level .gitattributes will be expressed mostly in terms of attributes based on what the files are, and the above sample would become like this: (built-in attribute configuration) [attr] binary !diff !crlf !merge-3way * diff crlf merge-3way (project specific .gitattributes) proprietary.o binary (user preference $GIT_DIR/info/attributes) *.ps !diff There are a few caveats. * As described above, you can define these macros only in $GIT_DIR/info/attributes and toplevel .gitattributes. * There is no attempt to detect circular definition of macro attributes, and definitions are evaluated from bottom to top as usual to fill in other attributes that have not yet got values. The following would work as expected: [attr] text diff crlf [attr] ps text !diff *.ps ps while this would most likely not (I haven't tried): [attr] ps text !diff [attr] text diff crlf *.ps ps * When a macro says "[attr] A B !C", saying that a path does not have attribute A does not let you tell anything about attributes B or C. That is, given this: [attr] text diff crlf [attr] ps text !diff *.txt !ps path hello.txt, which would match "*.txt" pattern, would have "ps" attribute set to zero, but that does not make text attribute of hello.txt set to false (nor diff attribute set to true).

This adds the basic infrastructure to assign attributes to paths, in a way similar to what the exclusion mechanism does based on $GIT_DIR/info/exclude and .gitignore files. An attribute is just a simple string that does not contain any whitespace. They can be specified in $GIT_DIR/info/attributes file, and .gitattributes file in each directory. Each line in these files defines a pattern matching rule. Similar to the exclusion mechanism, a later match overrides an earlier match in the same file, and entries from .gitattributes file in the same directory takes precedence over the ones from parent directories. Lines in $GIT_DIR/info/attributes file are used as the lowest precedence default rules. A line is either a comment (an empty line, or a line that begins with a '#'), or a rule, which is a whitespace separated list of tokens. The first token on the line is a shell glob pattern. The rest are names of attributes, each of which can optionally be prefixed with '!'. Such a line means "if a path matches this glob, this attribute is set (or unset -- if the attribute name is prefixed with '!'). For glob matching, the same "if the pattern does not have a slash in it, the basename of the path is matched with fnmatch(3) against the pattern, otherwise, the path is matched with the pattern with FNM_PATHNAME" rule as the exclusion mechanism is used. This does not define what an attribute means. Tying an attribute to various effects it has on git operation for paths that have it will be specified separately.

This merge strategy largely piggy-backs on git-merge-recursive. When merging trees A and B, if B corresponds to a subtree of A, B is first adjusted to match the tree structure of A, instead of reading the trees at the same level. This adjustment is also done to the common ancestor tree. If you are pulling updates from git-gui repository into git.git repository, the root level of the former corresponds to git-gui/ subdirectory of the latter. The tree object of git-gui's toplevel is wrapped in a fake tree object, whose sole entry has name 'git-gui' and records object name of the true tree, before being used by the 3-way merge code. If you are merging the other way, only the git-gui/ subtree of git.git is extracted and merged into git-gui's toplevel. The detection of corresponding subtree is done by comparing the pathnames and types in the toplevel of the tree. Heuristics galore! That's the git way ;-).

When defined, this allows plumbing commands that update the index (add, apply, checkout-index, merge-recursive, mv, read-tree, rm, update-index, and write-tree) to write their resulting index to an alternative index file while holding a lock to the original index file. With this, git-commit that jumps the index does not have to make an extra copy of the index file, and more importantly, it can do the update while holding the lock on the index. However, I think the interface to let an environment variable specify the output is a mistake, as shown in the documentation. If a curious user has the environment variable set to something other than the file GIT_INDEX_FILE points at, almost everything will break. This should instead be a command line parameter to tell these plumbing commands to write the result in the named file, to prevent stupid mistakes. Signed-off-by: NJunio C Hamano <junkio@cox.net>

The new configuration variable core.deltaBaseCacheLimit allows the user to control how much memory they are willing to give to Git for caching base objects of deltas. This is not normally meant to be a user tweakable knob; the "out of the box" settings are meant to be suitable for almost all workloads. We default to 16 MiB under the assumption that the cache is not meant to consume all of the user's available memory, and that the cache's main purpose was to cache trees, for faster path limiters during revision traversal. Since trees tend to be relatively small objects, this relatively small limit should still allow a large number of objects. On the other hand we don't want the cache to start storing 200 different versions of a 200 MiB blob, as this could easily blow the entire address space of a 32 bit process. We evict OBJ_BLOB from the cache first (credit goes to Junio) as we want to favor OBJ_TREE within the cache. These are the objects that have the highest inflate() startup penalty, as they tend to be small and thus don't have that much of a chance to ammortize that penalty over the entire data.

Especially with the new index format to come, it is more appropriate to encapsulate more into check_packed_git_idx() and assume less of the index format in struct packed_git. To that effect, the index_base is renamed to index_data with void * type so it is not used directly but other pointers initialized with it. This allows for a couple pointer cast removal, as well as providing a better generic name to grep for when adding support for new index versions or formats.
