From fdb3034e725ccf2c7be11871fcc374ced436983e Mon Sep 17 00:00:00 2001 From: Russell Belfer Date: Thu, 25 Apr 2013 14:57:13 -0700 Subject: Reorganize diff code into functions In preparation for more changes to the internal diff logic, it seemed wise to split the very large git_diff__from_iterators into separate functions that handle the four main cases (unmatched old item, unmatched new item, unmatched new directory, and matched old and new items). Hopefully this will keep the logic easier to follow even as more cases have to be added to this code. --- src/diff.c | 377 +++++++++++++++++++++++++++++++++---------------------------- 1 file changed, 202 insertions(+), 175 deletions(-) (limited to 'src/diff.c') diff --git a/src/diff.c b/src/diff.c index 6612abf06..58c7eacc6 100644 --- a/src/diff.c +++ b/src/diff.c @@ -530,24 +530,30 @@ cleanup: return result; } +typedef struct { + git_repository *repo; + git_iterator *old_iter; + git_iterator *new_iter; + const git_index_entry *oitem; + const git_index_entry *nitem; + git_buf ignore_prefix; +} diff_in_progress; + #define MODE_BITS_MASK 0000777 static int maybe_modified( - git_iterator *old_iter, - const git_index_entry *oitem, - git_iterator *new_iter, - const git_index_entry *nitem, - git_diff_list *diff) + git_diff_list *diff, + diff_in_progress *info) { git_oid noid, *use_noid = NULL; git_delta_t status = GIT_DELTA_MODIFIED; + const git_index_entry *oitem = info->oitem; + const git_index_entry *nitem = info->nitem; unsigned int omode = oitem->mode; unsigned int nmode = nitem->mode; - bool new_is_workdir = (new_iter->type == GIT_ITERATOR_TYPE_WORKDIR); + bool new_is_workdir = (info->new_iter->type == GIT_ITERATOR_TYPE_WORKDIR); const char *matched_pathspec; - GIT_UNUSED(old_iter); - if (!git_pathspec_match_path( &diff->pathspec, oitem->path, DIFF_FLAG_IS_SET(diff, GIT_DIFF_DISABLE_PATHSPEC_MATCH), @@ -692,6 +698,168 @@ static bool entry_is_prefixed( item->path[pathlen] == '/'); } +static int handle_unmatched_new_directory( + git_diff_list *diff, diff_in_progress *info, git_delta_t *delta) +{ + int error = 0; + const git_index_entry *nitem = info->nitem; + bool contains_oitem = entry_is_prefixed(diff, info->oitem, nitem); + bool recurse_into_dir = + (*delta == GIT_DELTA_UNTRACKED && + DIFF_FLAG_IS_SET(diff, GIT_DIFF_RECURSE_UNTRACKED_DIRS)) || + (*delta == GIT_DELTA_IGNORED && + DIFF_FLAG_IS_SET(diff, GIT_DIFF_RECURSE_IGNORED_DIRS)); + + /* do not advance into directories that contain a .git file */ + if (!contains_oitem && recurse_into_dir) { + git_buf *full = NULL; + if (git_iterator_current_workdir_path(&full, info->new_iter) < 0) + return -1; + if (git_path_contains_dir(full, DOT_GIT)) + recurse_into_dir = false; + } + + /* if directory is ignored, remember ignore_prefix */ + if ((contains_oitem || recurse_into_dir) && + *delta == GIT_DELTA_UNTRACKED && + git_iterator_current_is_ignored(info->new_iter)) + { + git_buf_sets(&info->ignore_prefix, info->nitem->path); + *delta = GIT_DELTA_IGNORED; + + /* skip recursion if we've just learned this is ignored */ + if (DIFF_FLAG_ISNT_SET(diff, GIT_DIFF_RECURSE_IGNORED_DIRS)) + recurse_into_dir = false; + } + + if (contains_oitem || recurse_into_dir) { + /* advance into directory */ + error = git_iterator_advance_into(&info->nitem, info->new_iter); + + /* if directory is empty, can't advance into it, so skip */ + if (error == GIT_ENOTFOUND) { + giterr_clear(); + error = git_iterator_advance(&info->nitem, info->new_iter); + + git_buf_clear(&info->ignore_prefix); + } + + /* return UNMODIFIED to tell caller not to create a new record */ + *delta = GIT_DELTA_UNMODIFIED; + } + + return error; +} + +static int handle_unmatched_new_item( + git_diff_list *diff, diff_in_progress *info) +{ + int error = 0; + const git_index_entry *nitem = info->nitem; + git_delta_t delta_type = GIT_DELTA_UNTRACKED; + + /* check if contained in ignored parent directory */ + if (git_buf_len(&info->ignore_prefix) && + diff->pfxcomp(nitem->path, git_buf_cstr(&info->ignore_prefix)) == 0) + delta_type = GIT_DELTA_IGNORED; + + if (S_ISDIR(nitem->mode)) { + error = handle_unmatched_new_directory(diff, info, &delta_type); + + if (error || delta_type == GIT_DELTA_UNMODIFIED) + return error; + } + + /* In core git, the next two "else if" clauses are effectively + * reversed -- i.e. when an untracked file contained in an + * ignored directory is individually ignored, it shows up as an + * ignored file in the diff list, even though other untracked + * files in the same directory are skipped completely. + * + * To me, this is odd.

This makes the default behavior no longer take that shortcut and instead look inside the untracked directory to see if there are any untracked files within it. If there are not, then the directory is treated as an ignore directory instead of an untracked directory. This has implications for the git_status APIs. --- src/diff.c | 203 +++++++++++++++++++++++++++++++++++++++++++------------------ 1 file changed, 143 insertions(+), 60 deletions(-) (limited to 'src/diff.c') diff --git a/src/diff.c b/src/diff.c index 58c7eacc6..cea3fdb22 100644 --- a/src/diff.c +++ b/src/diff.c @@ -698,56 +698,58 @@ static bool entry_is_prefixed( item->path[pathlen] == '/');
