Merge branch 'sl/clean-d-ignored-fix' into maint

2017-06-13T20:27:02Z

"git clean -d" used to clean directories that has ignored files, even though the command should not lose ignored ones without "-x". "git status --ignored" did not list ignored and untracked files without "-uall". These have been corrected. * sl/clean-d-ignored-fix: clean: teach clean -d to preserve ignored paths dir: expose cmp_name() and check_contains() dir: hide untracked contents of untracked dirs dir: recurse into untracked dirs for ignored files t7061: status --ignored should search untracked dirs t7300: clean -d should skip dirs with ignored files

dir: expose cmp_name() and check_contains()

2017-05-22T03:14:13Z

We want to use cmp_name() and check_contains() (which both compare `struct dir_entry`s, the former in terms of the sort order, the latter in terms of whether one lexically contains another) outside of dir.c, so we have to (1) change their linkage and (2) rename them as appropriate for the global namespace. The second is achieved by renaming cmp_name() to cmp_dir_entry() and check_contains() to check_dir_entry_contains(). Signed-off-by: Samuel Lijin Signed-off-by: Junio C Hamano

dir: hide untracked contents of untracked dirs

2017-05-22T03:14:09Z

When we taught read_directory_recursive() to recurse into untracked directories in search of ignored files given DIR_SHOW_IGNORED_TOO, that had the side effect of teaching it to collect the untracked contents of untracked directories. It doesn't always make sense to return these, though (we do need them for `clean -d`), so we introduce a flag (DIR_KEEP_UNTRACKED_CONTENTS) to control whether or not read_directory() strips dir->entries of the untracked contents of untracked dirs. We also introduce check_contains() to check if one dir_entry corresponds to a path which contains the path corresponding to another dir_entry. This also fixes known breakages in t7061, since status --ignored now searches untracked directories for ignored files. Signed-off-by: Samuel Lijin Signed-off-by: Junio C Hamano

dir: recurse into untracked dirs for ignored files

2017-05-22T03:06:52Z

We consider directories containing only untracked and ignored files to be themselves untracked, which in the usual case means we don't have to search these directories. This is problematic when we want to collect ignored files with DIR_SHOW_IGNORED_TOO, though, so we teach read_directory_recursive() to recurse into untracked directories to find the ignored files they contain when DIR_SHOW_IGNORED_TOO is set. This has the side effect of also collecting all untracked files in untracked directories as well. Signed-off-by: Samuel Lijin Signed-off-by: Junio C Hamano

Merge branch 'bw/attr-pathspec'

The pathspec mechanism learned to further limit the paths that match the pattern to those that have specified attributes attached via the gitattributes mechanism. * bw/attr-pathspec: pathspec: allow escaped query values pathspec: allow querying for attributes

connect_work_tree_and_git_dir: safely create leading directories

2017-03-16T01:15:53Z

In a later patch we'll use connect_work_tree_and_git_dir when the directory for the gitlink file doesn't exist yet. This patch makes connect_work_tree_and_git_dir safe to use for both cases of either the git dir or the working dir missing. To do so, we need to call safe_create_leading_directories[_const] on both directories. However this has to happen before we construct the absolute paths as real_pathdup assumes the directories to be there already. So for both the config file in the git dir as well as the .git link file we need to a) construct the name b) call SCLD c) get the absolute path d) once a-c is done for both we can consume the absolute path to compute the relative path to each other and store those relative paths. The implementation provided here puts a) and b) for both cases first, and then performs c and d after. One of the two users of 'connect_work_tree_and_git_dir' already checked for the directory being there, so we can loose that check as connect_work_tree_and_git_dir handles this functionality now.

pathspec: allow querying for attributes

2017-03-13T22:28:54Z

The pathspec mechanism is extended via the new ":(attr:eol=input)pattern/to/match" syntax to filter paths so that it requires paths to not just match the given pattern but also have the specified attrs attached for them to be chosen.

real_pathdup(): fix callsites that wanted it to die on error

2017-03-08T22:38:41Z

In 4ac9006f832 (real_path: have callers use real_pathdup and strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path()) pattern to use real_pathdup() directly. The problem with this change is that real_path() calls strbuf_realpath() with die_on_error = 1 while real_pathdup() calls it with die_on_error = 0. Meaning that in cases where real_path() causes Git to die() with an error message, real_pathdup() is silent and returns NULL instead. The callers, however, are ill-prepared for that change, as they expect the return value to be non-NULL (and otherwise the function died with an appropriate error message). Fix this by extending real_pathdup()'s signature to accept the die_on_error flag and simply pass it through to strbuf_realpath(), and then adjust all callers after a careful audit whether they would handle NULLs well.

dir: avoid allocation in fill_directory()

2017-02-08T21:38:41Z

Pass the match member of the first pathspec item directly to read_directory() instead of using common_prefix() to duplicate it first, thus avoiding memory duplication, strlen(3) and free(3). Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano
