2014-03-14Merge branch 'jc/check-attr-honor-working-tree'Libravatar Junio C Hamano1-22/+40
"git check-attr" when (trying to) work on a repository with a working tree did not work well when the working tree was specified via --work-tree (and obviously with --git-dir). The command also works in a bare repository but it reads from the (possibly stale, irrelevant and/or nonexistent) index, which may need to be fixed to read from HEAD, but that is a completely separate issue. As a related tangent to this separate issue, we may want to also fix "check-ignore", which refuses to work in a bare repository, to also operate in a bare one. * jc/check-attr-honor-working-tree: check-attr: move to the top of working tree when in non-bare repository t0003: do not chdir the whole test process
2014-03-11t0008: skip trailing space test on WindowsLibravatar Johannes Sixt1-1/+1
The Windows API does not preserve file names with trailing spaces (and dots), but rather strips them. Our tools (MSYS bash, git) base the POSIX emulation on the Windows API. As a consequence, it is impossible for bash on Windows to allocate a file whose name has trailing spaces, and for git to stat such a file. Both operate on a file whose name has the spaces stripped. Skip the test that needs such a file name. Note that we do not use (another incarnation of) prerequisite FUNNYNAMES. The reason is that FUNNYNAMES is intended to represent a property of the file system. But the inability to have trailing spaces in a file name is a property of the Windows API. The file system (NTFS) does not have this limitation. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-02-24diff: do not quit early on stat-dirty filesLibravatar Nguyễn Thái Ngọc Duy1-0/+6
When QUICK is set (i.e. with --quiet) we try to do as little work as possible, stopping after seeing the first change. stat-dirty is considered a "change" but it may turn out not, if no actual content is changed. The actual content test is performed too late in the process and the shortcut may be taken prematurely, leading to incorrect return code. Assume we do "git diff --quiet". If we have a stat-dirty file "a" and a really dirty file "b". We break the loop in run_diff_files() and stop after "a" because we have got a "change". Later in diffcore_skip_stat_unmatch() we find out "a" is actually not changed. But there's nothing else in the diff queue, we incorrectly declare "no change", ignoring the fact that "b" is changed. This also happens to "git diff --quiet HEAD" when it hits diff_can_quit_early() in oneway_diff(). This patch does the content test earlier in order to keep going if "a" is unchanged. The test result is cached so that when diffcore_skip_stat_unmatch() is done in the end, we spend no cycles on re-testing "a".

2014-02-24pathspec: pass directory indicator to match_pathspec_item()Libravatar Nguyễn Thái Ngọc Duy1-0/+6
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?

2014-02-24submodule: explicit local branch creation in module_cloneLibravatar W. Trevor King1-1/+38
The previous code only checked out branches in cmd_add. This commit moves the branch-checkout logic into module_clone, where it can be shared by cmd_add and cmd_update. I also update the initial checkout command to use 'reset' to preserve branches setup during module_clone. With this change, folks cloning submodules for the first time via: $ git submodule update ... will get a local branch instead of a detached HEAD, unless they are using the default checkout-mode updates. This is a change from the previous situation where cmd_update always used checkout-mode logic (regardless of the requested update mode) for updates that triggered an initial clone, which always resulted in a detached HEAD. This commit does not change the logic for updates after the initial clone, which will continue to create detached HEADs for checkout-mode updates, and integrate remote work with the local HEAD (detached or not) in other modes. The motivation for the change is that developers doing local work inside the submodule are likely to select a non-checkout-mode for updates so their local work is integrated with upstream work. Developers who are not doing local submodule work stick with checkout-mode updates so any apparently local work is blown away during updates. For example, if upstream rolls back the remote branch or gitlinked commit to an earlier version, the checkout-mode developer wants their old submodule checkout to be rolled back as well, instead of getting a no-op merge/rebase with the rolled-back reference. By using the update mode to distinguish submodule developers from black-box submodule consumers, we can setup local branches for the developers who will want local branches, and stick with detached HEADs for the developers that don't care. Testing ======= In t7406, just-cloned checkouts now update to the gitlinked hash with 'reset', to preserve the local branch for situations where we're not on a detached HEAD. I also added explicit tests to t7406 for HEAD attachement after cloning updates, showing that it depends on their update mode: * Checkout-mode updates get detached HEADs * Everyone else gets a local branch, matching the configured submodule.<name>.branch and defaulting to master. The 'initial-setup' tag makes it easy to reset the superproject to a known state, as several earlier tests commit to submodules and commit the changed gitlinks to the superproject, but don't push the new submodule commits to the upstream subprojects. This makes it impossible to checkout the current super master, because it references submodule commits that don't exist in the upstream subprojects. For a specific example, see the tests that currently generate the 'two_new_submodule_commits' commits. Documentation ============= I updated the docs to describe the 'submodule update' modes in detail. The old documentation did not distinguish between cloning and non-cloning updates and lacked clarity on which operations would lead to detached HEADs, and which would not. The new documentation addresses these issues while updating the docs to reflect the changes introduced by this commit's explicit local branch creation in module_clone. I also add '--checkout' to the usage summary and group the update-mode options into a single set. Signed-off-by: W. Trevor King <wking@tremily.us> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-02-24t3030-merge-recursive: test known breakage with empty work treeLibravatar Brad King1-0/+47
Sometimes when working with a large repository it can be useful to try out a merge and only check out conflicting files to disk (for example as a speed optimization on a server). Until v1.7.7-rc1~28^2~20 (merge-recursive: When we detect we can skip an update, actually skip it, 2011-08-11), it was possible to do so with the following idiom: # Prepare a temporary index and empty work tree. GIT_INDEX_FILE="$PWD/tmp-$$-index" && export GIT_INDEX_FILE && GIT_WORK_TREE="$PWD/tmp-$$-work" && export GIT_WORK_TREE && mkdir "$GIT_WORK_TREE" && # Convince the index that our side is on disk. git read-tree -i -m $ours && git update-index --ignore-missing --refresh && # Merge their side into our side. bases=$(git merge-base --all $ours $theirs) && git merge-recursive $bases -- $ours $theirs && tree=$(git write-tree) Nowadays, that still works and the exit status is the same, but merge-recursive produces a diagnostic if "our" side renamed a file: error: addinfo_cache failed for path 'dst' Add a test to document this regression.

2014-02-24remote: handle pushremote config in any orderLibravatar Jeff King1-0/+13
The remote we push can be defined either by remote.pushdefault or by branch.*.pushremote for the current branch. The order in which they appear in the config file should not matter to precedence (which should be to prefer the branch-specific config). The current code parses the config linearly and uses a single string to store both values, overwriting any previous value. Thus, config like: [branch "master"] pushremote = foo [remote] pushdefault = bar erroneously ends up pushing to "bar" from the master branch. We can fix this by storing both values and resolving the correct value after all config is read. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-02-24log: handle integer overflow in timestampsLibravatar Jeff King1-0/+16
If an ident line has a ridiculous date value like (2^64)+1, we currently just pass ULONG_MAX along to the date code, which can produce nonsensical dates. On systems with a signed long time_t (e.g., 64-bit glibc systems), this actually doesn't end up too bad. The ULONG_MAX is converted to -1, we apply the timezone field to that, and the result ends up somewhere between Dec 31, 1969 and Jan 1, 1970. However, there is still a few good reasons to detect the overflow explicitly: 1. On systems where "unsigned long" is smaller than time_t, we get a nonsensical date in the future. 2. Even where it would produce "Dec 31, 1969", it's easier to recognize "midnight Jan 1" as a consistent sentinel value for "we could not parse this". 3. Values which do not overflow strtoul but do overflow a signed time_t produce nonsensical values in the past. For example, on a 64-bit system with a signed long time_t, a timestamp of 18446744073000000000 produces a date in 1947. We also recognize overflow in the timezone field, which could produce nonsensical results. In this case we show the parsed date, but in UTC.

2014-02-24fsck: report integer overflow in author timestampsLibravatar Jeff King1-0/+14
When we check commit objects, we complain if commit->date is ULONG_MAX, which is an indication that we saw integer overflow when parsing it. However, we do not do any check at all for author lines, which also contain a timestamp. Let's actually check the timestamps on each ident line with strtoul. This catches both author and committer lines, and we can get rid of the now-redundant commit->date check. Note that like the existing check, we compare only against ULONG_MAX. Now that we are calling strtoul at the site of the check, we could be slightly more careful and also check that errno is set to ERANGE. However, this will make further refactoring in future patches a little harder, and it doesn't really matter in practice. For 32-bit systems, one would have to create a commit at the exact wrong second in 2038. But by the time we get close to that, all systems will hopefully have moved to 64-bit (and if they haven't, they have a real problem one second later). For 64-bit systems, by the time we get close to ULONG_MAX, all systems will hopefully have been consumed in the fiery wrath of our expanding Sun.

2014-02-24t4212: test bogus timestamps with git-logLibravatar Jeff King1-0/+21
When t4212 was originally added by 9dbe7c3d (pretty: handle broken commit headers gracefully, 2013-04-17), it tested our handling of commits with broken ident lines in which the timestamps could not be parsed. It does so using a bogus line like "Name <email>-<> 1234 -0000", because that simulates an error that was seen in the wild. Later, 03818a4 (split_ident: parse timestamp from end of line, 2013-10-14) made our parser smart enough to actually find the timestamp on such a line, and t4212 was adjusted to match. While it's nice that we handle this real-world case, this meant that we were not actually testing the bogus-timestamp case anymore. This patch adds a test with a totally incomprehensible timestamp to make sure we are testing the code path. Note that the behavior is slightly different between regular log output and "--format=%ad". In the former case, we produce a sentinel value and in the latter, we produce an empty string. While at first this seems unnecessarily inconsistent, it matches the original behavior given by 9dbe7c3d. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-02-24introduce GIT_INDEX_VERSION environment variableLibravatar Thomas Gummerer1-0/+49
Respect a GIT_INDEX_VERSION environment variable, when a new index is initialized. Setting the environment variable will not cause existing index files to be converted to another format, but will only affect newly written index files. This can be used to initialize repositories with index-v4.

2014-02-20stop using fnmatch (either native or compat)Libravatar Nguyễn Thái Ngọc Duy1-13/+0
Since v1.8.4 (about six months ago) wildmatch is used as default replacement for fnmatch. We have seen only one fix since so wildmatch probably has done a good job as fnmatch replacement. This concludes the fnmatch->wildmatch transition by no longer relying on fnmatch. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-02-20notes: disallow reusing non-blob as a note objectLibravatar Johan Herland1-0/+27
Currently "git notes add -C $object" will read the raw bytes from $object, and then copy those bytes into the note object, which is hardcoded to be of type blob. This means that if the given $object is a non-blob (e.g. tree or commit), the raw bytes from that object is copied into a blob object. This is probably not useful, and certainly not what any sane user would expect. So disallow it, by erroring out if the $object passed to the -C option is not a blob. The fix also applies to the -c option (in which the user is prompted to edit/verify the note contents in a text editor), and also when -c/-C is passed to "git notes append" (which appends the $object contents to an existing note object). In both cases, passing a non-blob $object does not make sense. Also add a couple of tests demonstrating expected behavior.

2014-02-18config: teach "git config --file -" to read from the standard inputLibravatar Kirill A. Shutemov2-3/+30
The patch extends git config --file interface to allow read config from stdin. Editing stdin or setting value in stdin is an error. Include by absolute path is allowed in stdin config, but not by relative path. Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name> Signed-off-by: Junio C Hamano <gitster@pobox.com>
