This is a micro-optimization that grew out of the mailing list discussion about "strlen()" showing up in profiles. We used to pass regular C strings around to the low-level tree walking routines, and while this worked fine, it meant that we needed to call strlen() on strings that the caller always actually knew the size of anyway. So pass the length of the string down wih the string, and avoid unnecessary calls to strlen(). Also, when extracting a pathname from a tree entry, use "tree_entry_len()" instead of strlen(), since the length of the pathname is directly calculable from the decoded tree entry itself without having to actually do another strlen(). This shaves off another ~5-10% from some loads that are very tree intensive (notably doing commit filtering by a pathspec).

We currently have two parallel notation for dealing with object types in the code: a string and a numerical value. One of them is obviously redundent, and the most used one requires more stack space and a bunch of strcmp() all over the place. This is an initial step for the removal of the version using a char array found in object reading code paths. The patch is unfortunately large but there is no sane way to split it in smaller parts without breaking the system.

This patch on top of 'next' makes built-in git-cherry handle root commits. It moves the static function log-tree.c::diff_root_tree() to tree-diff.c and makes it more similar to diff_tree_sha1() by shuffling around arguments and factoring out the call to log_tree_diff_flush(). Consequently the name is changed to diff_root_tree_sha1(). It is a version of diff_tree_sha1() that compares the empty tree (= root tree) against a single 'real' tree. This function is then used in get_patch_id() to compute patch IDs for initial commits instead of SEGFAULTing, as the current code does if confronted with parentless commits.

Introduces global inline: hashcmp(const unsigned char *sha1, const unsigned char *sha2) Uses memcmp for comparison and returns the result based on the length of the hash name (a future runtime decision).

The way tree-diff was set up assumed we would use only one set of pathspec during the entire life of the program. Move the pathspec related static variables out to diff_options structure so that we can filter commits with one set of paths while show the actual diffs using different set of paths. I suspect this breaks blame.c, and makes "git log paths..." to default to the --full-diff, the latter of which is dealt with the next commit. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This replaces occurences of "blob", "commit", "tag", and "tree", where they're really used as type specifiers, which we already have defined global constants for. Signed-off-by: NPeter Eriksen <s022018@student.dtu.dk> Signed-off-by: NJunio C Hamano <junkio@cox.net>

Introduce tree-walk.[ch] and move "struct tree_desc" and associated functions from various places. Rename DIFF_FILE_CANON_MODE(mode) macro to canon_mode(mode) and move it to cache.h. This macro returns the canonicalized st_mode value in the host byte order for files, symlinks and directories -- to be compared with a tree_desc entry. create_ce_mode(mode) in cache.h is similar but is intended to be used for index entries (so it does not work for directories) and returns the value in the network byte order.

We have operations to "extract" and "update" a "struct tree_desc", but we only used them in tree-diff.c and they were static to that file. But other tree traversal functions can use them to their advantage Signed-off-by: NLinus Torvalds <torvalds@osdl.org> Signed-off-by: NJunio C Hamano <junkio@cox.net>

This makes the tree diff functionality independent of the "git-diff-tree" program, by splitting the core functionality up into a library file. This will be needed for when we teach git-rev-list to only follow a specified set of pathnames, rather than the global revision history. Most of it is a fairly straightforward code move, but it also involves some calling convention cleanup, and moving some of the static variables from diff-tree.c into the options structure. The actual tree change callback routines also become paramterized by the diff_options structure, allowing the library functionality to do something else than just show the diff on stdout. Right now the only user of this functionality remains git-diff-tree itself. Signed-off-by: NLinus Torvalds <torvalds@osdl.org> Signed-off-by: NJunio C Hamano <junkio@cox.net>
