Make git-cherry handle root trees

2006-10-27T01:31:17Z

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.

Do not use memcmp(sha1_1, sha1_2, 20) with hardcoded length.

2006-08-17T21:23:53Z

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). Acked-by: Alex Riesen Signed-off-by: David Rientjes Signed-off-by: Junio C Hamano

tree-diff: do not assume we use only one pathspec

2006-04-10T23:45:19Z

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: Junio C Hamano

Use blob_, commit_, tag_, and tree_type throughout.

2006-04-04T07:11:19Z

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: Peter Eriksen Signed-off-by: Junio C Hamano

tree/diff header cleanup.

2006-03-30T07:54:13Z

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.

Make the "struct tree_desc" operations available to others

2006-02-01T00:07:01Z

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: Linus Torvalds Signed-off-by: Junio C Hamano

avoid asking ?alloc() for zero bytes.

2005-12-27T01:23:59Z

Avoid asking for zero bytes when that change simplifies overall logic. Later we would change the wrapper to ask for 1 byte on platforms that return NULL for zero byte request. Signed-off-by: Junio C Hamano

Split up tree diff functions into tree-diff.c library

2005-10-23T05:49:51Z

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: Linus Torvalds Signed-off-by: Junio C Hamano
