Nguyễn Thái Ngọc Duy	e721c1544f	checkout: avoid unnecessary match_pathspec calls In checkout_paths() we do this - for all updated items, call match_pathspec - for all items, call match_pathspec (inside unmerge_cache) - for all items, call match_pathspec (for showing "path .. is unmerged) - for updated items, call match_pathspec and update paths That's a lot of duplicate match_pathspec(s) and the function is not exactly cheap to be called so many times, especially on large indexes. This patch makes it call match_pathspec once per updated index entry, save the result in ce_flags and reuse the results in the following loops. The changes in `0a1283b` (checkout $tree $path: do not clobber local changes in $path not in $tree - 2011-09-30) limit the affected paths to ones we read from $tree. We do not do anything to other modified entries in this case, so the "for all items" above could be modified to "for all updated items". But.. The command's behavior now is modified slightly: unmerged entries that match $path, but not updated by $tree, are now NOT touched. Although this should be considered a bug fix, not a regression. A new test is added for this change. And while at there, free ps_matched after use. The following command is tested on webkit, 215k entries. The pattern is chosen mainly to make match_pathspec sweat: git checkout -- "[a-zA-Z][a-zA-Z][a-zA-Z]" before after real 0m3.493s 0m2.737s user 0m2.239s 0m1.586s sys 0m1.252s 0m1.151s Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Alex Riesen	8a57c6e943	Convert the users of for_each_string_list to for_each_string_list_item macro The rule for selecting the candidates for conversion is: if the callback function returns only 0 (the condition for for_each_string_list to exit early), than it can be safely converted to the macro. A notable exception are the callers in builtin/remote.c. If converted, the readability in the file will suffer greately. Besides, the code is not very performance critical (at the moment, at least): it does output formatting of the list of remotes.

Julian Phillips	e8c8b7139c	string_list: Fix argument order for string_list_lookup Update the definition and callers of string_list_lookup to use the string_list as the first argument. This helps make the string_list API easier to use by being more consistent. Signed-off-by: Julian Phillips <julian@quantumfyre.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago

Junio C Hamano	4421a82357	resolve-undo: "checkout -m path" uses resolve-undo information Once you resolved conflicts by "git add path", you cannot recreate the conflicted state with "git checkout -m path", because you lost information from higher stages in the index when you resolved them. Since we record the necessary information in the resolve-undo index extension these days, we can reproduce the unmerged state in the index and check it out.

Junio C Hamano	cfc5789ada	resolve-undo: record resolved conflicts in a new index extension section When resolving a conflict using "git add" to create a stage #0 entry, or "git rm" to remove entries at higher stages, remove_index_entry_at() function is eventually called to remove unmerged (i.e. higher stage) entries from the index. Introduce a "resolve_undo_info" structure and keep track of the removed cache entries, and save it in a new index extension section in the index_state. Operations like "read-tree -m", "merge", "checkout [-m] <branch>" and "reset" are signs that recorded information in the index is no longer necessary. The data is removed from the index extension when operations start; they may leave conflicted entries in the index, and later user actions like "git add" will record their conflicted states afresh.
