2013-06-13use logical OR (||) instead of binary OR (|) in logical contextRené Scharfe
The compiler can short-circuit the evaluation of conditions strung together with logical OR operators instead of computing the resulting bitmask with binary ORs. More importantly, this patch makes the intent of the changed code clearer, because the logical context (as opposed to binary context) becomes immediately obvious. While we're at it, simplify the check for patch->is_rename in builtin/apply.c a bit; it can only be 0 or 1, so we don't need a comparison operator.

2013-01-16clean.c, ls-files.c: respect encapsulation of exclude_list_groupsAdam Spiers
Consumers of the dir.c traversal API should avoid assuming knowledge of the internal implementation of exclude_list_groups. Therefore when adding items to an exclude list, it should be accessed via the pointer returned from add_exclude_list(), rather than by referencing a location within dir.exclude_list_groups[EXC_CMDL].

2013-01-06dir.c: keep track of where patterns came fromAdam Spiers
For exclude patterns read in from files, the filename is stored in the exclude list, and the originating line number is stored in the individual exclude (counting starting at 1). For exclude patterns provided on the command line, a string describing the source of the patterns is stored in the exclude list, and the sequence number assigned to each exclude pattern is negative, with counting starting at -1. So for example the 2nd pattern provided via --exclude would be numbered -2. This allows any future consumers of that data to easily distinguish between exclude patterns from files vs. from the CLI.

2013-01-06dir.c: use a single struct exclude_list per source of excludesAdam Spiers
Previously each exclude_list could potentially contain patterns from multiple sources. For example dir->exclude_list[EXC_FILE] would typically contain patterns from .git/info/exclude and core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain patterns from multiple per-directory .gitignore files during directory traversal (i.e. when dir->exclude_stack was more than one item deep). We split these composite exclude_lists up into three groups of exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each exclude_list now contains patterns from a single source. This will allow us to cleanly track the origin of each pattern simply by adding a src field to struct exclude_list, rather than to struct exclude, which would make memory management of the source string tricky in the EXC_DIRS case where its contents are dynamically generated. Similarly, by moving the filebuf member from struct exclude_stack to struct exclude_list, it allows us to track and subsequently free memory buffers allocated during the parsing of all exclude files, rather than only tracking buffers allocated for files in the EXC_DIRS group.

We mark pathspec with wildcards with the field use_wildcard. We could do better by saving the length of the non-wildcard part, which can be used for optimizations such as f9f6e2c (exclude: do strcmp as much as possible before fnmatch - 2012-06-07).

2012-06-06path_excluded(): update API to less cache-entry centricJunio C Hamano
It was stupid of me to make the API too much cache-entry specific; the caller may want to check arbitrary pathname without having a corresponding cache-entry to see if a path is ignored. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-06-03ls-files -i: pay attention to exclusion of leading pathsJunio C Hamano
"git ls-files --exclude=t/ -i" does not show paths in directory t/ that have been added to the index, but it should. The excluded() API was designed for callers who walk the tree from the top, checking each level of the directory hierarchy as it descends if it is excluded, and not even bothering to recurse into an excluded directory. This would allow us optimize for a common case by not having to check if the exclude pattern "foo/" matches when looking at "foo/bar", because the caller should have noticed that "foo" is excluded and did not even bother to read "foo/bar" out of opendir()/readdir() to call it. The code for "ls-files -i" however walks the index linearly, feeding paths without checking if the leading directory is already excluded. Introduce a helper function path_excluded() to let this caller properly call excluded() check for higher hierarchies as necessary. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-09-06remove prefix argument from pathspec_prefixClemens Buchacher
Passing a prefix to a function that is supposed to find the prefix is strange. And it's really only used if the pathspec is NULL. Make the callers handle this case instead. As we are always returning a fresh copy of a string (or NULL), change the type of the returned value to non-const "char *".

* cb/maint-ls-files-error-report: ls-files: fix pathspec display on error
2011-08-11ls-files: fix pathspec display on errorClemens Buchacher
The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.

2011-08-02commit: allow partial commits with relative pathsClemens Buchacher
In order to do partial commits, git-commit overlays a tree on the cache and checks pathspecs against the result. Currently, the overlaying is done using "prefix" which prevents relative pathspecs with ".." and absolute pathspec from matching when they refer to files not under "prefix" and absent from the index, but still in the tree (i.e. files staged for removal). The point of providing a prefix at all is performance optimization. If we say there is no common prefix for the files of interest, then we have to read the entire tree into the index. But even if we cannot use the working directory as a prefix, we can still figure out if there is a common prefix for all given paths, and use that instead. The pathspec_prefix() routine from ls-files.c does exactly that. Any use of global variables is removed from pathspec_prefix() so that it can be called from commit.c.

2011-04-05pathspec: rename per-item field has_wildcard to use_wildcardJunio C Hamano
As the point of the last change is to allow use of strings as literals no matter what characters are in them, "has_wildcard" does not match what we use this field for anymore. It is used to decide if the wildcard matching should be used, so rename it to match the usage better. Signed-off-by: Junio C Hamano <gitster@pobox.com>

This patch changes behavior of the two functions. Previously it does prefix matching only. Now it can also do wildcard matching. All callers are updated. Some gain wildcard matching (archive, checkout), others reset pathspec_item.has_wildcard to retain old behavior (ls-files, ls-tree as they are plumbing).

Part of a campaign to avoid git <command> -h being distracted by access to the repository.

2010-07-05Convert the users of for_each_string_list to for_each_string_list_item macroAlex Riesen
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.

This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities?

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.
