libify git-ls-files directory traversal This moves the core directory traversal and filename exclusion logic into the general git library, making it available for other users directly. If we ever want to do "git commit" or "git add" as a built-in (and we do), we want to be able to handle most of git-ls-files as a library. NOTE! Not all of git-ls-files is libified by this. The index matching and pathspec prefix calculation is still in ls-files.c, but this is a big part of it.

struct dir_entry {
builtin-add: simplify (and increase accuracy of) exclude handling Previously, the code would always set up the excludes, and then manually pick through the pathspec we were given, assuming that non-added but existing paths were just ignored. This was mostly correct, but would erroneously mark a totally empty directory as 'ignored'. Instead, we now use the collect_ignored option of dir_struct, which unambiguously tells us whether a path was ignored. This simplifies the code, and means empty directories are now just not mentioned at all. Furthermore, we now conditionally ask dir_struct to respect excludes, depending on whether the '-f' flag has been set. This means we don't have to pick through the result, checking for an 'ignored' flag; ignored entries were either added or not in the first place. We can safely get rid of the special 'ignored' flags to dir_entry, which were not used anywhere else.

gitignore(5): Allow "foo/" in ignore list to match directory "foo" A pattern "foo/" in the exclude list did not match directory "foo", but a pattern "foo" did. This attempts to extend the exclude mechanism so that it would while not matching a regular file or a symbolic link "foo". In order to differentiate a directory and non directory, this passes down the type of path being checked to excluded() function. A downside is that the recursive directory walk may need to run lstat(2) more often on systems whose "struct dirent" do not give the type of the entry; earlier it did not have to do so for an excluded path, but we now need to figure out if a path is a directory before deciding to exclude it. This is especially bad because an idea similar to the earlier CE_UPTODATE optimization to reduce number of lstat(2) calls would by definition not apply to the codepaths involved, as (1) directories will not be registered in the index, and (2) excluded paths will not be in the index anyway.

Add 'fill_directory()' helper function for directory traversal Most of the users of "read_directory()" actually want a much simpler interface than the whole complex (but rather powerful) one. In fact 'git add' had already largely abstracted out the core interface issues into a private "fill_directory()" function that was largely applicable almost as-is to a number of callers. Yes, 'git add' wants to do some extra work of its own, specific to the add semantics, but we can easily split that out, and use the core as a generic function. This function does exactly that, and now that much simplified 'fill_directory()' function can be shared with a number of callers, while also ensuring that the rather more complex calling conventions of read_directory() are used by fewer call-sites. This also makes the 'common_prefix()' helper function private to dir.c, since all callers are now in that file.

core.excludesfile clean-up There are inconsistencies in the way commands currently handle the core.excludesfile configuration variable. The problem is the variable is too new to be noticed by anything other than git-add and git-status. * git-ls-files does not notice any of the "ignore" files by default, as it predates the standardized set of ignore files. The calling scripts established the convention to use .git/info/exclude, .gitignore, and later core.excludesfile. * git-add and git-status know about it because they call add_excludes_from_file() directly with their own notion of which standard set of ignore files to use. This is just a stupid duplication of code that need to be updated every time the definition of the standard set of ignore files is changed. * git-read-tree takes --exclude-per-directory=<gitignore>, not because the flexibility was needed. Again, this was because the option predates the standardization of the ignore files. * git-merge-recursive uses hardcoded per-directory .gitignore and nothing else. git-clean (scripted version) does not honor core.* because its call to underlying ls-files does not know about it. git-clean in C (parked in 'pu') doesn't either. We probably could change git-ls-files to use the standard set when no excludes are specified on the command line and ignore processing was asked, or something like that, but that will be a change in semantics and might break people's scripts in a subtle way. I am somewhat reluctant to make such a change. On the other hand, I think it makes perfect sense to fix git-read-tree, git-merge-recursive and git-clean to follow the same rule as other commands. I do not think of a valid use case to give an exclude-per-directory that is nonstandard to read-tree command, outside a "negative" test in the t1004 test script. This patch is the first step to untangle this mess. The next step would be to teach read-tree, merge-recursive and clean (in C) to use setup_standard_excludes().

remove_dir_recursively(): Add flag for skipping removal of toplevel dir Add the REMOVE_DIR_KEEP_TOPLEVEL flag to remove_dir_recursively() for deleting everything inside the given directory, but _not_ the given directory itself. Note that this does not pass the REMOVE_DIR_KEEP_NESTED_GIT flag, if set, to the recursive invocations of remove_dir_recursively(). It is likely to be a a bug that has been present since REMOVE_DIR_KEEP_NESTED_GIT was introduced (a0f4afb), but this commit keeps the same behaviour for now.

Introduce remove_dir_recursively() There was a function called remove_empty_dir_recursive() buried in refs.c. Expose a slightly enhanced version in dir.h: it can now optionally remove a non-empty directory.

Add remove_path: a function to remove as much as possible of a path The function has two potential users which both managed to get wrong their implementations (the one in builtin-rm.c one has a memleak, and builtin-merge-recursive.c scribles over its const argument).

Add string comparison functions that respect the ignore_case variable. Multiple locations within this patch series alter a case sensitive string comparison call such as strcmp() to be a call to a string comparison call that selects case comparison based on the global ignore_case variable. Behaviorally, when core.ignorecase=false, the *_icase() versions are functionally equivalent to their C runtime counterparts. When core.ignorecase=true, the *_icase() versions perform a case insensitive comparison. Like Linus' earlier ignorecase patch, these may ignore filename conventions on certain file systems. By isolating filename comparisons to certain functions, support for those filename conventions may be more easily met.

libify git-ls-files directory traversal This moves the core directory traversal and filename exclusion logic into the general git library, making it available for other users directly. If we ever want to do "git commit" or "git add" as a built-in (and we do), we want to be able to handle most of git-ls-files as a library. NOTE! Not all of git-ls-files is libified by this. The index matching and pathspec prefix calculation is still in ls-files.c, but this is a big part of it.
