2017-04-18ls-files: fix path used when recursing into submodulesLibravatar Jacob Keller1-1/+4
Don't assume that the current working directory is the root of the repository. Correctly generate the path for the recursing child processes by building it from the work_tree() root instead. Otherwise if we run ls-files using --git-dir or --work-tree it will not work correctly as it attempts to change directory into a potentially invalid location. Best case, it doesn't exist and we produce an error. Worst case we cd into the wrong location and unknown behavior occurs. Add a new test which highlights this possibility.

2017-04-17ls-files: fix recurse-submodules with nested submodulesLibravatar Jacob Keller1-0/+4
Since commit e77aa336f116 ("ls-files: optionally recurse into submodules", 2016-10-07) ls-files has known how to recurse into submodules when displaying files. Unfortunately this fails for certain cases, including when nesting more than one submodule, called from within a submodule that itself has submodules, or when the GIT_DIR environemnt variable is set. Prior to commit b58a68c1c187 ("setup: allow for prefix to be passed to git commands", 2017-03-17) this resulted in an error indicating that --prefix and --super-prefix were incompatible. After this commit, instead, the process loops forever with a GIT_DIR set to the parent and continuously reads the parent submodule files and recursing forever. Fix this by preparing the environment properly for submodules when setting up the child process. This is similar to how other commands such as grep behave. This was not caught by the original tests because the scenario is avoided if the submodules are created separately and not stored as the standard method of putting the submodule git directory under .git/modules/<name>. We can update the test to show the failure by the addition of "git submodule absorbgitdirs" to the test case. However, note that this new test would run forever without the necessary fix in this patch. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-17ls-files: fix bug when recursing with relative pathspecLibravatar Brandon Williams1-12/+13
When using the --recurse-submodules flag with a relative pathspec which includes "..", an error is produced inside the child process spawned for a submodule. When creating the pathspec struct in the child, the ".." is interpreted to mean "go up a directory" which causes an error stating that the path ".." is outside of the repository. While it is true that ".." is outside the scope of the submodule, it is confusing to a user who originally invoked the command where ".." was indeed still inside the scope of the superproject. Since the child process launched for the submodule has some context that it is operating underneath a superproject, this error could be avoided. This patch fixes the bug by passing the 'prefix' to the child process. Now each child process that works on a submodule has two points of reference to the superproject: (1) the 'super_prefix' which is the path from the root of the superproject down to root of the submodule and (2) the 'prefix' which is the path from the root of the superproject down to the directory where the user invoked the git command. With these two pieces of information a child process can correctly interpret the pathspecs provided by the user as well as being able to properly format its output relative to the directory the user invoked the original command from.

2017-02-13ls-files: move only kept cache entries in prune_cache()Libravatar René Scharfe1-5/+4
prune_cache() first identifies those entries at the start of the sorted array that can be discarded. Then it moves the rest of the entries up. Last it identifies the unwanted trailing entries among the moved ones and cuts them off. Change the order: Identify both start *and* end of the range to keep first and then move only those entries to the top. The resulting code is slightly shorter and a bit more efficient.

2016-10-10ls-files: add pathspec matching for submodulesLibravatar Brandon Williams1-6/+21
Pathspecs can be a bit tricky when trying to apply them to submodules. The main challenge is that the pathspecs will be with respect to the superproject and not with respect to paths in the submodule. The approach this patch takes is to pass in the identical pathspec from the superproject to the submodule in addition to the submodule-prefix, which is the path from the root of the superproject to the submodule, and then we can compare an entry in the submodule prepended with the submodule-prefix to the pathspec in order to determine if there is a match. This patch also permits the pathspec logic to perform a prefix match against submodules since a pathspec could refer to a file inside of a submodule. Due to limitations in the wildmatch logic, a prefix match is only done literally. If any wildcard character is encountered we'll simply punt and produce a false positive match. More accurate matching will be done once inside the submodule. This is due to the superproject not knowing what files could exist in the submodule.

2016-01-18ls-files: add eol diagnosticsLibravatar Torsten Bögershausen1-0/+21
When working in a cross-platform environment, a user may want to check if text files are stored normalized in the repository and if .gitattributes are set appropriately. Make it possible to let Git show the line endings in the index and in the working tree and the effective text/eol attributes. The end of line ("eolinfo") are shown like this: "-text" binary (or with bare CR) file "none" text file without any EOL "lf" text file with LF "crlf" text file with CRLF "mixed" text file with mixed line endings. The effective text/eol attribute is one of these: "", "-text", "text", "text=auto", "text eol=lf", "text eol=crlf" git ls-files --eol gives an output like this: i/none w/none attr/text=auto t/t5100/empty i/-text w/-text attr/-text t/test-binary-2.png i/lf w/lf attr/text eol=lf t/t5100/rfc2047-info-0007 i/lf w/crlf attr/text eol=crlf doit.bat i/mixed w/mixed attr/ locale/XX.po to show what eol convention is used in the data in the index ('i'), and in the working tree ('w'), and what attribute is in effect, for each path that is shown.

2015-03-24report_path_error(): move to dir.cLibravatar Junio C Hamano1-43/+0
The expected call sequence is for the caller to use match_pathspec() repeatedly on a set of pathspecs, accumulating the "hits" in a separate array, and then call this function to diagnose a pathspec that never matched anything, as that can indicate a typo from the command line, e.g. "git commit Maekfile". Many builtin commands use this function from builtin/ls-files.c, which is not a very healthy arrangement. ls-files might have been the first command to feel the need for such a helper, but the need is shared by everybody who uses the "match and then report" pattern.

2014-02-24pathspec: pass directory indicator to match_pathspec_item()Libravatar Nguyễn Thái Ngọc Duy1-2/+3
This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce the same output. Previously only the version without trailing slash returns the difference (if any). That's the effect of new ce_path_match(). dir_path_match() is not executed by the new tests. And it should not introduce regressions. Previously if path "dir/" is passed in with pathspec "dir/", they obviously match. With new dir_path_match(), the path becomes _directory_ "dir" vs pathspec "dir/", which is not executed by the old code path in m_p_i(). The new code path is executed and produces the same result. The other case is pathspec "dir" and path "dir/" is now turned to "dir" (with DO_MATCH_DIRECTORY). Still the same result before or after the patch. So why change?

2013-08-15ls-files -k: a directory only can be killed if the index has a non-directoryLibravatar Junio C Hamano1-0/+2
"ls-files -o" and "ls-files -k" both traverse the working tree down to find either all untracked paths or those that will be "killed" (removed from the working tree to make room) when the paths recorded in the index are checked out. It is necessary to traverse the working tree fully when enumerating all the "other" paths, but when we are only interested in "killed" paths, we can take advantage of the fact that paths that do not overlap with entries in the index can never be killed. The treat_one_path() helper function, which is called during the recursive traversal, is the ideal place to implement an optimization. When we are looking at a directory P in the working tree, there are three cases: (1) P exists in the index. Everything inside the directory P in the working tree needs to go when P is checked out from the index. (2) P does not exist in the index, but there is P/Q in the index. We know P will stay a directory when we check out the contents of the index, but we do not know yet if there is a directory P/Q in the working tree to be killed, so we need to recurse. (3) P does not exist in the index, and there is no P/Q in the index to require P to be a directory, either. Only in this case, we know that everything inside P will not be killed without recursing. Note that this helper is called by treat_leading_path() that decides if we need to traverse only subdirectories of a single common leading directory, which is essential for this optimization to be correct. This caller checks each level of the leading path component from shallower directory to deeper ones, and that is what allows us to only check if the path appears in the index. If the call to treat_one_path() weren't there, given a path P/Q/R, the real traversal may start from directory P/Q/R, even when the index records P as a regular file, and we would end up having to check if any leading subpath in P/Q/R, e.g. P, appears in the index.

2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleLibravatar Nguyễn Thái Ngọc Duy1-6/+6
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.

2013-06-26quote.c: substitute path_relative with relative_pathLibravatar Jiang Xin1-2/+7
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.

2013-06-13use logical OR (||) instead of binary OR (|) in logical contextLibravatar René Scharfe1-4/+4
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_groupsLibravatar Adam Spiers1-5/+10
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 fromLibravatar Adam Spiers1-2/+3
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 excludesLibravatar Adam Spiers1-3/+5
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.
