2012-04-24git p4: fix-up "import/export of labels to/from p4"Libravatar Luke Diamand1-2/+2

2012-04-11git p4: import/export of labels to/from p4Libravatar Luke Diamand1-0/+202
The existing label import code looks at each commit being imported, and then checks for labels at that commit. This doesn't work in the real world though because it will drop labels applied on changelists that have already been imported, a common pattern. This change adds a new --import-labels option. With this option, at the end of the sync, git p4 gets sets of labels in p4 and git, and then creates a git tag for each missing p4 label. This means that tags created on older changelists are still imported. Tags that could not be imported are added to an ignore list. The same sets of git and p4 tags and labels can also be used to derive a list of git tags to export to p4. This is enabled with --export-labels in 'git p4 submit'.

2012-03-16Merge "two fixes for fast-import's 'ls' command" from JonathanLibravatar Junio C Hamano1-0/+39
Andrew Sayers noticed that the svn-fe | git fast-import pipeline mishandles a subversion history that copies the root directory to a sub-directory (e.g. doing `svn cp . trunk` to standardise your layout). As David Barr explained, the bug arises when the following command is sent to git fast-import: 'ls' SP ':1' SP LF Instead of reading back what is at the root of r1, it unconditionally reports the path as missing. After sleeping on it, here are two patches for 'maint'. One plugs a memory leak. The other ensures that trying to pass an empty path to the 'ls' command results in an error message that can help the frontend author instead of the silently broken conversion Andrew found. Then we can carefully add 'ls ""' support in 1.7.11. * commit 'refs/pull-request-tags/jn/maint-fast-import-empty-ls': fast-import: don't allow 'ls' of path with empty components fast-import: leakfix for 'ls' of dirty trees

2012-03-09fast-import: don't allow 'ls' of path with empty componentsLibravatar Jonathan Nieder1-0/+39
As the fast-import manual explains: The value of <path> must be in canonical form. That is it must not: . contain an empty directory component (e.g. foo//bar is invalid), . end with a directory separator (e.g. foo/ is invalid), . start with a directory separator (e.g. /foo is invalid), Unfortunately the "ls" command accepts these invalid syntaxes and responds by declaring that the indicated path is missing. This is too subtle and causes importers to silently misbehave; better to error out so the operator knows what's happening. The C, R, and M commands already error out for such paths.

2012-03-09t0204: clarify the "observe undefined behaviour" testLibravatar Junio C Hamano1-14/+23
This test asks for an impossible conversion to the system by preparing an UTF-8 translation with characters that cannot be expressed in ISO-8859-1, and then asking the message shown in ISO-8859-1. Even though the behaviour against such a request is undefined, it may be interesting to see what the system does, and the purpose of this test is to see if there are platforms that exhibit behaviour that we haven't seen. The original recognized two known modes of behaviour: - the key used to query the message catalog ("TEST: Old English Runes"), saying "I cannot do that i18n". - impossible characters replaced with ASCII "?", saying "I punt". but they were treated totally differently. The test simply issued an informational message "Your system punts on this one" for the first error mode, while it diagnosed the latter as "Your system is good; you pass!". It turns out that Mac OS X exhibits a third mode of error behaviour, to spew out the raw value stored in the message catalog. The test diagnosed this behaviour as "broken", but it is merely trying to do its best to respond to an impossible request by saying "I punt" in a way that is slightly different from the second one. Update the offending test to make it clear what is (and is not) being tested, update the code structure so that newly discovered error mode can easily be added to it later, and reword the message that comes from a failing case to clarify that it is not the system that is broken when it fails, but merely that the behaviour is not something we have seen.

2012-03-04submodules: refactor computation of relative gitdir pathLibravatar Jens Lehmann1-0/+17
In module_clone() the rel_gitdir variable was computed differently when "git rev-parse --git-dir" returned a relative path than when it returned an absolute path. This is not optimal, as different code paths are used depending on the return value of that command. Fix that by reusing the differing path components computed for setting the core.worktree config setting, which leaves a single code path for setting both instead of having three and makes the code much shorter. This also fixes the bug that in the computation of how many directories have to be traversed up to hit the root directory of the submodule the name of the submodule was used where the path should have been used. This lead to problems after renaming submodules into another directory level. Even though the "(cd $somewhere && pwd)" approach breaks the flexibility of symlinks, that is no issue here as we have to have one relative path pointing from the work tree to the gitdir and another pointing back, which will never work anyway when a symlink along one of those paths is changed because the directory it points to was moved. Also add a test moving a submodule into a deeper directory to catch any future breakage here and to document what has to be done when a submodule needs to be moved until git mv learns to do that. Simply moving it to the new location doesn't work, as the core.worktree and possibly the gitfile setting too will be wrong. So it has to be removed from filesystem and index, then the new location has to be added into the index and the .gitmodules file has to be updated. After that a git submodule update will check out the submodule at the new location. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-03-04submodules: always use a relative path from gitdir to work treeLibravatar Jens Lehmann1-0/+20
Since recently a submodule with name <name> has its git directory in the .git/modules/<name> directory of the superproject while the work tree contains a gitfile pointing there. To make that work the git directory has the core.worktree configuration set in its config file to point back to the work tree. That core.worktree is an absolute path set by the initial clone of the submodule. A relative path is preferable here because it allows the superproject to be moved around without invalidating that setting, so compute and set that relative path after cloning or reactivating the submodule. This also fixes a bug when moving a submodule around inside the superproject, as the current code forgot to update the setting to the new submodule work tree location. Enhance t7400 to ensure that future versions won't re-add absolute paths by accident and that moving a superproject won't break submodules.

2012-03-04submodules: always use a relative path to gitdirLibravatar Jens Lehmann1-0/+2
Since recently a submodule with name <name> has its git directory in the .git/modules/<name> directory of the superproject while the work tree contains a gitfile pointing there. When the submodule git directory needs to be cloned because it is not found in .git/modules/<name> the clone command will write an absolute path into the gitfile. When no clone is necessary the git directory will be reactivated by the git-submodule.sh script by writing a relative path into the gitfile. This is inconsistent, as the behavior depends on the submodule having been cloned before into the .git/modules of the superproject. A relative path is preferable here because it allows the superproject to be moved around without invalidating the gitfile. We do that by always writing the relative path into the gitfile, which overwrites the absolute path the clone command may have written there. This is only the first step to make superprojects movable again like they were before the separate-git-dir approach was introduced. The second step is to use a relative path in core.worktree too. Enhance t7400 to ensure that future versions won't re-add absolute paths by accident. While at it also replace an if/else construct evaluating the presence of the 'reference' option with a single line of bash code.

2012-03-02t0300: work around bug in dash 0.5.6Libravatar Michael J Gruber1-1/+4
The construct 'while IFS== read' makes dash 0.5.6 execute read without changing IFS, which results in test breakages all over the place in t0300. Neither dash 0.5.5.1 and older nor dash 0.5.7 and newer are affected: The problem was introduded resp. fixed by the commits 55c46b7 ([BUILTIN] Honor tab as IFS whitespace when splitting fields in readcmd, 2009-08-11) 1d806ac ([VAR] Do not poplocalvars prematurely on regular utilities, 2010-05-27) in http://git.kernel.org/?p=utils/dash/dash.git Putting 'IFS==' before that line makes all versions of dash work. This looks like a dash bug, not a misinterpretation of the standard. However, it's worth working around for two reasons. One, this version of dash was released in Fedora 14-16, so the bug is found in the wild. And two, at least one other shell, Solaris /bin/sh, choked on this by persisting IFS after the read invocation. That is not a shell we usually care about, and I think this use of IFS is acceptable by POSIX (which allows other behavior near "special builtins", but "read" is not one of those). But it seems that this may be a subtle, not-well-tested case for some shells. Given that the workaround is so simple, it's worth just being defensive.

2012-03-01bundle: keep around names passed to add_pending_object()Libravatar Thomas Rast1-0/+15
The 'name' field passed to add_pending_object() is used to later deduplicate in object_array_remove_duplicates(). git-bundle had a bug in this area since 18449ab (git-bundle: avoid packing objects which are in the prerequisites, 2007-03-08): it passed the name of each boundary object in a static buffer. In other words, all that object_array_remove_duplicates() saw was the name of the *last* added boundary object. The recent switch to a strbuf in bc2fed4 (bundle: use a strbuf to scan the log for boundary commits, 2012-02-22) made this slightly worse: we now free the buffer at the end, so it is not even guaranteed that it still points into addressable memory by the time object_array_remove_ duplicates looks at it. On the plus side however, it was now detectable by valgrind. The fix is easy: pass a copy of the string to add_pending_object.

2012-03-01diff -p: squelch "diff --git" header for stat-dirty pathsLibravatar Junio C Hamano1-4/+1
The plumbing "diff" commands look at the working tree files without refreshing the index themselves for performance reasons (the calling script is expected to do that upfront just once, before calling one or more of them). In the early days of git, they showed the "diff --git" header before they actually ask the xdiff machinery to produce patches, and ended up showing only these headers if the real contents are the same and the difference they noticed was only because the stat info cached in the index did not match that of the working tree. It was too late for the implementation to take the header that it already emitted back. But 3e97c7c (No diff -b/-w output for all-whitespace changes, 2009-11-19) introduced necessary logic to keep the meta-information headers in a strbuf and delay their output until the xdiff machinery noticed actual changes. This was primarily in order to generate patches that ignore whitespaces. When operating under "-w" mode, we wouldn't know if the header is needed until we actually look at the resulting patch, so it was a sensible thing to do, but we did not realize that the same reasoning applies to stat-dirty paths. Later, 296c6bb (diff: fix "git show -C -C" output when renaming a binary file, 2010-05-26) generalized this machinery and added must_show_header toggle. This is turned on when the header must be shown even when there is no patch to be produced, e.g. only the mode was changed, or the path was renamed, without changing the contents. However, when it did so, it still kept the special case for the "-w" mode, which meant that the plumbing would keep showing these phantom changes. This corrects this historical inconsistency by allowing the plumbing to omit paths that are only stat-dirty from its output in the same way as it handles whitespace only changes under "-w" option. The change in the behaviour can be seen in the updated test. Signed-off-by: Junio C Hamano <gitster@pobox.com>

The plumbing that looks at the working tree, i.e. "diff-index" and "diff-files", always emit the "diff --git a/path b/path" header lines without anything else for paths that are only stat-dirty (i.e. different only because the cached stat information in the index no longer matches that of the working tree, but the real contents are the same), when these commands are run with "-p" option to produce patches. Illustrate this current behaviour. Also demonstrate that with the "-w" option, we (correctly) hold off showing a "diff --git" header until actual differences have been found. This also suppresses the header for merely stat-dirty files, which is inconsistent. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-03-01t4011: modernise styleLibravatar Junio C Hamano1-86/+82
Match the style to more modern test scripts, namely: - The first line of each test has prereq, title and opening sq for the script body. This makes the test shorter while reducing the need for backslashes. - Be prepared for the case in which the previous test may have failed. If a test wants to start from not having "frotz" that the previous test may have created, write "rm -f frotz", not "rm frotz". - Prepare the expected output inside your own test. - The order of comparison to check the result is "diff expected actual", so that the output will show how the output from the git you just broke is different from what is expected. - Write no SP between redirection '>' (or '<' for that matter) and the filename.
