2015-01-14standardize usage info string formatAlex Henrie
This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <> Reviewed-by: Matthieu Moy <> Signed-off-by: Junio C Hamano <>

2014-06-13update-index: new options to enable/disable split index modeNguyễn Thái Ngọc Duy
If you have a large work tree but only make changes in a subset, then $GIT_DIR/index's size should be stable after a while. If you change branches that touch something else, $GIT_DIR/index's size may grow large that it becomes as slow as the unified index. Do --split-index again occasionally to force all changes back to the shared index and keep $GIT_DIR/index small. Signed-off-by: Nguyễn Thái Ngọc Duy <> Signed-off-by: Junio C Hamano <>

2014-06-04update-index: fix segfault with missing --cacheinfo argumentJeff King
Running "git update-index --cacheinfo" without any further arguments results in a segfault rather than an error message. Commit ec160ae (update-index: teach --cacheinfo a new syntax "mode,sha1,path", 2014-03-23) added code to examine the format of the argument, but forgot to handle the NULL case. Returning an error from the parser is enough, since we then treat it as an old-style "--cacheinfo <mode> <sha1> <path>", and complain that we have less than 3 arguments to read.

2014-03-24update-index: teach --cacheinfo a new syntax "mode,sha1,path"Junio C Hamano
The "--cacheinfo" option is unusual in that it takes three option parameters. An option with an optional parameter is bad enough. An option with multiple parameters is simply insane. Introduce a new syntax that takes these three things concatenated together with a comma, which makes the command line syntax more uniform across subcommands, while retaining the traditional syntax for backward compatiblity. If we were designing the "update-index" subcommand from scratch today, it may probably have made sense to make this option (and possibly others) a command mode option that does not take any option parameter (hence no need for arg-help). But we do not live in such an ideal world, and as far as I can tell, the command still supports (and must support) mixed command modes in a single invocation, e.g. $ git update-index path1 --add path2 \ --cacheinfo 100644 $(git hash-object --stdin -w <path3) path3 \ path4 must make sure path1 is already in the index and update all of these four paths. So this is probably as far as we can go to fix this issue without risking to break people's existing scripts. Signed-off-by: Junio C Hamano <>

2013-11-18read-cache.c: fix memory leaks caused by removed cache entriesKarsten Blees
When cache_entry structs are removed from index_state.cache, they are not properly freed. Freeing those entries wasn't possible before because we couldn't remove them from index_state.name_hash. Now that we _do_ remove the entries from name_hash, we can also free them. Add 'free(cache_entry)' to all call sites of name-hash.c::remove_name_hash in read-cache.c (we could free() directly in remove_name_hash(), but name-hash.c isn't concerned with cache_entry allocation at all). Accessing a cache_entry after removing it from the index is now no longer allowed, as the memory has been freed. The following functions need minor fixes (typically by copying ce->name before use): - builtin/rm.c::cmd_rm - builtin/update-index.c::do_reupdate - read-cache.c::read_index_unmerged - resolve-undo.c::unmerge_index_entry_at Signed-off-by: Karsten Blees <> Signed-off-by: Junio C Hamano <>
2013-11-18builtin/update-index.c: cleanup update_oneKarsten Blees
do_reupdate calls update_one with a, there's no need for the extra sanitation / normalization that happens in prefix_path. cmd_update_index calls update_one with an already prefixed path, no need to prefix_path twice. Remove the extra prefix_path from update_one. Also remove the now unused 'prefix' and 'prefix_length' parameters. As of d089eba "setup: sanitize absolute and funny paths in get_pathspec()", prefix_path uncoditionally returns a copy, even if the passed in path isn't changed. Lets unconditionally free() the result. Signed-off-by: Karsten Blees <> Signed-off-by: Junio C Hamano <>

2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleNguyễn Thái Ngọc Duy
I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

2012-11-02update-index/diff-index: use core.preloadindex to improve performanceKarsten Blees
'update-index --refresh' and 'diff-index' (without --cached) don't honor the core.preloadindex setting yet. Porcelain commands using these (such as git [svn] rebase) suffer from this, especially on Windows. Use read_cache_preload to improve performance. Additionally, in builtin/diff.c, don't preload index status if we don't access the working copy (--cached).

2012-07-11Strip namelen out of ce_flags into a ce_namelen fieldThomas Gummerer
Strip the name length from the ce_flags field and move it into its own ce_namelen field in struct cache_entry. This will both give us a tiny bit of a performance enhancement when working with long pathnames and is a refactoring for more readability of the code. It enhances readability, by making it more clear what is a flag, and where the length is stored and make it clear which functions use stages in comparisions and which only use the length. It also makes CE_NAMEMASK private, so that users don't mistakenly write the name length in the flags. Signed-off-by: Thomas Gummerer <> Signed-off-by: Junio C Hamano <>

2012-06-11update-index: allow overwriting existing submodule index entriesHeiko Voigt
In commit e01105 Linus introduced gitlinks to update-index. He explains that he thinks it is not the right thing to replace a gitlink with something else. That commit is from the very first beginnings of submodule support. Since then we have gotten a lot closer to being able to remove a submodule without losing its history. This check prevents such a use case, so I think this assumption has changed. Additionally in the git add codepath we do not have such a check, so for consistency reasons I think removing this check is the correct thing to do.

2010-12-07update-index: migrate to parse-options APIJonathan Nieder
--refresh and --really-refresh accept flags (like -q) and modify an error indicator. It might make sense to make the error indicator global, but just pass the flags and a pointer to the error indicator in a struct instead. --cacheinfo wants 3 arguments. Use the OPTION_LOWLEVEL_CALLBACK extension to grab them and PARSE_OPT_NOARG to disallow the "sticked" --cacheinfo=foo form. (The resulting message $ git update-index --cacheinfo=foo error: option `cacheinfo' takes no value is unfortunately incorrect.) --assume-unchanged and --no-assume-unchanged probably should use the OPT_UYN feature; but use a callback for now so the existing MARK_FLAG and UNMARK_FLAG values can be used. --stdin and --index-info are still constrained to be the last argument (implemented using the OPTION_LOWLEVEL_CALLBACK extension). --unresolve and --again consume all arguments that come after them (also using OPTION_LOWLEVEL_CALLBACK). The order of options matters. Each path on the command line is affected only by the options that come before it. A custom argument-parsing loop with parse_options_step() brings that about. In exchange for all the fuss, we get the usual perks: support for un-sticked options, better usage error messages, more useful -h output, and argument parsing code that should be easier to tweak in the future.

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <> Signed-off-by: Junio C Hamano <>
