[PATCH] Make "git-ls-files" work in subdirectories This makes git-ls-files work inside a relative directory, and also adds some rudimentary filename globbing support. For example, in the kernel you can now do cd arch/i386 git-ls-files and it will show all files under that subdirectory (and it will have removed the "arch/i386/" prefix unless you give it the "--full-name" option, so that you can feed the result to "xargs grep" or similar). The filename globbing is kind of strange: it does _not_ follow normal globbing rules, although it does look "almost" like a normal file glob (and it uses the POSIX.2 "fnmatch()" function). The glob pattern (there can be only one) is always split into a "directory part" and a "glob part", where the directory part is defined as any full directory path without any '*' or '?' characters. The "glob" part is whatever is left over. For example, when doing git-ls-files 'arch/i386/p*/*.c' the "directory part" is is "arch/i386/", and the "glob part" is "p*/*.c". The directory part will be added to the prefix, and handled efficiently (ie we will not be searching outside of that subdirectory), while the glob part (if anything is left over) will be used to trigger "fnmatch()" matches. This is efficient and very useful, but can result in somewhat non-intuitive behaviour. For example: git-ls-files 'arch/i386/*.[ch]' will find all .c and .h files under arch/i386/, _including_ things in lower subdirectories (ie it will match "arch/i386/kernel/process.c", because "kernel/process.c" will match the "*.c" specifier). Also, while git-ls-files arch/i386/ will show all files under that subdirectory, doing the same without the final slash would try to show the file "i386" under the "arch/" subdirectory, and since there is no such file (even if there is such a _directory_) it will not match anything at all. These semantics may not seem intuitive, but they are actually very practical. In particular, it makes it very simple to do git-ls-files fs/*.c | xargs grep some_pattern and it does what you want.

quote.c: substitute path_relative with relative_path Substitute the function path_relative in quote.c with the function relative_path. Function relative_path can be treated as an enhanced and more robust version of path_relative. Outputs of path_relative and it's replacement (relative_path) are the same for the following cases: path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a/b/c/ /a/b/ c/ c/ /a/b/c /a/b/ c c /a/ /a/b/ ../ ../ / /a/b/ ../../ ../../ /a/c /a/b/ ../c ../c /x/y /a/b/ ../../x/y ../../x/y a/b/c/ a/b/ c/ c/ a/ a/b/ ../ ../ x/y a/b/ ../../x/y ../../x/y /a/b (empty) /a/b /a/b /a/b (null) /a/b /a/b a/b (empty) a/b a/b a/b (null) a/b a/b But if both of the path and the prefix are the same, or the returned relative path should be the current directory, the outputs of both functions are different. Function relative_path returns "./", while function path_relative returns empty string. path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a/b/ /a/b/ (empty) ./ a/b/ a/b/ (empty) ./ (empty) (null) (empty) ./ (empty) (empty) (empty) ./ But the callers of path_relative can handle such cases, or never encounter this issue at all, because: * In function quote_path_relative, if the output of path_relative is empty, append "./" to it, like: if (!out->len) strbuf_addstr(out, "./"); * Another caller is write_name_quoted_relative, which is only used by builtin/ls-files.c. git-ls-files only show files, so path of files will never be identical with the prefix of a directory. The following differences show that path_relative does not handle extra slashes properly: path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a//b//c/ //a/b// ../../../../a//b//c/ c/ a/b//c a//b ../b//c c And if prefix has no trailing slash, path_relative does not work properly either. But since prefix always has a trailing slash, it's not a problem. path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a/b/c/ /a/b b/c/ c/ /a/b /a/b b ./ /a/b/ /a/b b/ ./ /a /a/b/ ../../a ../ a/b/c/ a/b b/c/ c/ a/b/ a/b b/ ./ a a/b ../a ../ x/y a/b/ ../x/y ../../x/y a/c a/b c ../c /a/ /a/b (empty) ../ (empty) /a/b ../../ ./ One tricky part in this conversion is write_name() function in ls-files.c. It takes a counted string, <name, len>, that is to be made relative to <prefix, prefix_len> and then quoted. Because write_name_quoted_relative() still takes these two parameters as counted string, but ignores the count and treat these two as NUL-terminated strings, this conversion needs to be audited for its callers: - For <name, len>, all three callers of write_name() passes a NUL-terminated string and its true length, so this patch makes "len" unused. - For <prefix, prefix_len>, prefix could be a string that is longer than empty while prefix_len could be 0 when "--full-name" option is used. This is fixed by checking prefix_len in write_name() and calling write_name_quoted_relative() with NULL when prefix_len is set to 0. Again, this makes "prefix_len" given to write_name_quoted_relative() unused, without introducing a bug.

Convert "struct cache_entry *" to "const ..." wherever possible 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.

For example, in the kernel you can now do cd arch/i386 git-ls-files and it will show all files under that subdirectory (and it will have removed the "arch/i386/" prefix unless you give it the "--full-name" option, so that you can feed the result to "xargs grep" or similar).

Convert "struct cache_entry *" to "const ..." wherever possible 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.

[PATCH] git-ls-files: generalized pathspecs This generalizes the git "glob" string to be a lot more like the git-diff-* pathspecs (but there are still differences: the diff family doesn't do any globbing, and because the diff family always generates the full native pathname, it doesn't have the issue with ".."). It does three things: - it allows multiple matching strings, ie you can do things like git-ls-files arch/i386/ include/asm-i386/ | xargs grep pattern - the "matching" criteria is a combination of "exact path component match" (the same as the git-diff-* family), and "fnmatch()". However, you should be careful with the confusion between the git-ls-files internal globbing and the standard shell globbing, ie git-ls-files fs/*.c does globbing in the shell, and does something totally different from git-ls-files 'fs/*.c' which does the globbing inside git-ls-files. The latter has _one_ pathspec with a wildcard, and will match any .c file anywhere under the fs/ directory, while the former has been expanded by the shell into having _lots_ of pathspec entries, all of which are just in the top-level fs/ subdirectory. They will happily be matched exactly, but we will thus miss all the subdirectories under fs/. As a result, the first one will (on the current kernel) match 55 files, while the second one will match 664 files! - it uses the generic path prefixing, so that ".." and friends at the beginning of the path spec work automatically NOTE! When generating relative pathname output (the default), a pathspec that causes the base to be outside the current working directory will be rejected with an error message like: fatal: git-ls-files: cannot generate relative filenames containing '..' because we do not actually generate ".." in the output. However, the ".." format works fine for the --full-name case: cd arch/i386/kernel git-ls-files --full-name ../mm/ results in arch/i386/mm/Makefile arch/i386/mm/boot_ioremap.c arch/i386/mm/discontig.c arch/i386/mm/extable.c arch/i386/mm/fault.c arch/i386/mm/highmem.c arch/i386/mm/hugetlbpage.c arch/i386/mm/init.c arch/i386/mm/ioremap.c arch/i386/mm/mmap.c arch/i386/mm/pageattr.c arch/i386/mm/pgtable.c Perhaps more commonly, the generic path prefixing means that "." and "./" automatically get simplified and work properly.

[PATCH] Make "git-ls-files" work in subdirectories This makes git-ls-files work inside a relative directory, and also adds some rudimentary filename globbing support. For example, in the kernel you can now do cd arch/i386 git-ls-files and it will show all files under that subdirectory (and it will have removed the "arch/i386/" prefix unless you give it the "--full-name" option, so that you can feed the result to "xargs grep" or similar). The filename globbing is kind of strange: it does _not_ follow normal globbing rules, although it does look "almost" like a normal file glob (and it uses the POSIX.2 "fnmatch()" function). The glob pattern (there can be only one) is always split into a "directory part" and a "glob part", where the directory part is defined as any full directory path without any '*' or '?' characters. The "glob" part is whatever is left over. For example, when doing git-ls-files 'arch/i386/p*/*.c' the "directory part" is is "arch/i386/", and the "glob part" is "p*/*.c". The directory part will be added to the prefix, and handled efficiently (ie we will not be searching outside of that subdirectory), while the glob part (if anything is left over) will be used to trigger "fnmatch()" matches. This is efficient and very useful, but can result in somewhat non-intuitive behaviour. For example: git-ls-files 'arch/i386/*.[ch]' will find all .c and .h files under arch/i386/, _including_ things in lower subdirectories (ie it will match "arch/i386/kernel/process.c", because "kernel/process.c" will match the "*.c" specifier). Also, while git-ls-files arch/i386/ will show all files under that subdirectory, doing the same without the final slash would try to show the file "i386" under the "arch/" subdirectory, and since there is no such file (even if there is such a _directory_) it will not match anything at all. These semantics may not seem intuitive, but they are actually very practical. In particular, it makes it very simple to do git-ls-files fs/*.c | xargs grep some_pattern and it does what you want.
