e509db9 cvsserver: Fix for histories with multiple roots Git histories may have multiple roots, which can cause git merge-base to fail and this caused git cvsserver to die.

3a9f0f4 parse-options: catch likely typo in presense of aggregated options. If options are aggregated, and that the whole token is an exact prefix of a long option that is longer than 2 letters, reject it. This is to prevent a common typo: $ git commit -amend to get interpreted as "commit all with message 'end'". The typo check isn't performed if there is no aggregation, because the stuck form is the recommended one. If we have `-o` being a valid short option that takes an argument, and --option a long one, then we _MUST_ accept -option as "'o' option with argument 'ption'", which is our official recommended form.

81cc66a Makefile: customization for supporting HP-UX Signed-off-by: Robert Schiele <rschiele@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com> 25 January 2008, 05:58:53 UTC
2600973 pre-POSIX.1-2001 systems do not have <sys/select.h> POSIX.1-2001 has declaration of select(2) in <sys/select.h>, but in the previous version of SUS, it was declared in <sys/time.h> (which is already included in git-compat-util.h). This introduces NO_SYS_SELECT_H macro in the Makefile to be set on older systems, to skip inclusion of <sys/select.h> that does not exist on them. We could check _POSIX_VERSION with 200112L and do this automatically, but earlier it was reported that the approach does not work well on some vintage of HP-UX. Other systems may get _POSIX_VERSION itself wrong. At least for now, this manual configuration is safer.

5a9dd39 git-commit: exit non-zero if we fail to commit the index In certain rare cases, the creation of the commit object and update of HEAD can succeed, but then installing the updated index will fail. This is most likely caused by a full disk or exceeded disk quota. When this happens the new index file will be removed, and the repository will be left with the original now-out-of-sync index. The user can recover with a "git reset HEAD" once the disk space issue is resolved. We should detect this failure and offer the user some helpful guidance.

3b8f19a git-gui: Correctly cleanup msgfmt '1 message untranslated' output In the multiple message case we remove the word "messages" from the statistics output of msgfmt as it looks cleaner on the tty when you are watching the build process. However we failed to strip the word "message" when only 1 message was found to be untranslated or fuzzy, as msgfmt does not produce the 's' suffix. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> 23 January 2008, 04:56:15 UTC
2cd9ad2 git-gui: Make the statistics of po2msg match those of msgfmt The strings we were showing from po2msg didn't exactly match those of msgfmt's --statistics output so we didn't show quite the same results when building git-gui's message files. Now we're closer to what msgfmt shows (at least for an en_US locale) so the make output matches. I noticed that the fuzzy translation count is off by one for the current po/zh_cn.po file. Not sure why and I'm not going to try and debug it at this time as the po2msg is strictly a fallback, users building from source really should prefer msgfmt. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> 23 January 2008, 04:52:07 UTC
3470ada git-gui: Fallback to Tcl based po2msg.sh if msgfmt isn't available If msgfmt fails with exit code 127 that typically means the program is not found in the user's PATH and thus cannot be executed by make. In such a case we can try to fallback to the Tcl based po2msg program that we distributed with git-gui, as it does a "good enough" job. We still don't default to po2msg.sh however as it does not perform a lot of the sanity checks that msgfmt does, and quite a few of those are too useful to give up. Signed-off-by: Shawn O.

3ddff72 git-gui: Work around random missing scrollbar in revision list If the horizontal scrollbar isn't currently visible (because it has not been needed) but we get an update to the scroll port we may find the scrollbar window exists but the Tcl command doesn't.

6fc7470 pack-objects: Fix segfault when object count is less than thread count When partitioning the work amongst threads, dividing the number of objects by the number of threads may return 0 when there are less objects than threads; this will cause the subsequent code to segfault when accessing list[sub_size-1].

bb23fdf Teach fast-import to honor pack.compression and pack.depth We now use the configured pack.compression and pack.depth values within fast-import, as like builtin-pack-objects fast-import is generating a packfile for consumption by the Git tools. We use the same behavior as builtin-pack-objects does for these options, allowing core.compression to supply the default value for pack.compression. The default setting for pack.depth within fast-import is still 10 as users will generally repack fast-import generated packfiles by `repack -f`. A large delta depth within the fast-import packfile can significantly slow down such a later repack. Signed-off-by: Shawn O.

a2d93ae git-submodule: add test for the subcommand parser fix This modifies the existing t7400 test to use 'init' as the pathname that a submodule is bound to. Without the earlier subcommand parser fix, this fails. Signed-off-by: Junio C Hamano <gitster@pobox.com> 21 January 2008, 04:57:42 UTC
5c08dbb git-submodule: fix subcommand parser The subcommand parser of "git submodule" made its subcommand names reserved words. As a consequence, a command like this: $ git submodule add init update which is meant to add a submodule called 'init' at path 'update' was misinterpreted as a request to invoke more than one mutually incompatible subcommands and incorrectly rejected. This patch fixes the issue by stopping the subcommand parsing at the first subcommand word, to allow the sample command line above to work as expected. It also introduces the usual -- option disambiguator, so that a submodule at path '-foo' can be updated with $ git submodule update -- -foo without triggering an "unrecognized option -foo" error.

23a485e git-submodule: rename shell functions for consistency This renames the shell functions used in git-submodule that implement top-level subcommands.

6caaf2d git-gui: Correct encoding of glossary/fr.po to UTF-8 Junio noticed this was incorrectly added in ISO-8859-1 but it should be in UTF-8 (as the headers claim UTF-8, and our convention is to use only UTF-8). Signed-off-by: Shawn O. Pearce <spearce@spearce.org> 21 January 2008, 04:03:23 UTC
ed76cb7 git-gui: Consolidate hook execution code into a single function The code we use to test if a hook is executable or not differs on Cygwin from the normal POSIX case. Rather then repeating that for all three hooks we call in our commit code path we can place the common logic into a global procedure and invoke it when necessary. This also lets us get rid of the ugly "|& cat" we were using before as we can now rely on the Tcl 8.4 feature of "2>@1" or fallback to the "|& cat" when necessary. The post-commit hook is now run through the same API, but its outcome does not influence the commit status. As a result we now show any of the errors from the post-commit hook in a dialog window, instead of on the user's tty that was used to launch git-gui. This resolves a long standing bug related to not getting errors out of the post-commit hook when launched under git-gui. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> 21 January 2008, 03:45:38 UTC

fb0ca47 git-gui: Honor the standard commit-msg hook Under core Git the git-commit tool will invoke the commit-msg hook if it exists and is executable to the user running git-commit. As a hook it has some limited value as it cannot alter the commit, but it can modify the message the user is attempting to commit. It is also able to examine the message to ensure it conforms to some local standards/conventions. Since the hook takes the name of a temporary file holding the message as its only parameter we need to move the code that creates the temp file up earlier in our commit code path, and then pass through that file name to the latest stage (where we call git-commit-tree). We let the hook alter the file as it sees fit and we don't bother to look at its content again until the commit succeeded and we need the subject for the reflog update. Signed-off-by: Shawn O.

325ce39 http-push: clarify the reason of error from the initial PROPFIND request The first thing http-push does is a PROPFIND to see if the other end supports locking. The failure message we give is always reported as "no DAV locking support at the remote repository", regardless of the reason why we ended up not finding the locking support on the other end. This moves the code to report "no DAV locking support" down the codepath so that the message is issued only when we successfully get a response to PROPFIND and the other end say it does not support locking. Other failures, such as connectivity glitches and credential mismatches, have their own error message issued and we will not issue "no DAV locking" error (we do not even know if the remote end supports it).

9bdbaba http-push: fail when info/refs exists and is already locked Failing instead of silently not updating remote refs makes the things clearer for the user when trying to push on a repository while another person do (or while a dandling locks are waiting for a 10 minutes timeout).

9116de5 http-push: fix webdav lock leak. Releasing webdav lock even if push fails because of bad (or no) reference on command line. To reproduce the issue that this patch fixes, prepare a test repository availlable over http+webdav, say at http://myhost/myrepo.git/ Then: $ git clone http://myhost/myrepo.git/ $ cd myrepo $ git push http Fetching remote heads... refs/ refs/heads/ refs/tags/ No refs in common and none specified; doing nothing. $ git push http Fetching remote heads... refs/ refs/heads/ refs/tags/ No refs in common and none specified; doing nothing. $ Finally, you look at the web server logs, and will find one LOCK query and no UNLOCK query, of course the second one will be in 423 return code instead of 200: 1.2.3.4 - gb [19/Jan/2008:14:24:56 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 200 465 (...) 1.2.3.4 - gb [19/Jan/2008:14:25:10 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 423 363 With this patch, there would have be two UNLOCKs in addition of the LOCKs From the user's point of view: - If you realize that you should have typed e.g. "git push http master" instead of "git push http", you will have to wait for 10 minutes for the lock to expire by its own. - Furthermore, if somebody else is dumb enough to type "git push http" while you need to push "master" branch, then you'll need too to wait for 10 minutes too.

0a61779 parse_commit_buffer: tighten checks while parsing This tightens the parsing of a commit object in a couple of ways. - The "tree " header must end with a LF (earlier we did not check this condition). - Make sure parsing of timestamp on the "committer " header does not go beyond the buffer, even when (1) the "author " header does not end with a LF (this means that the commit object is malformed and lacks the committer information) or (2) the "committer " header does not have ">" that is the end of the e-mail address, or (3) the "committer " header does not end with a LF. We however still keep the existing behaviour to return a parsed commit object even when non-structural headers such as committer and author are malformed, so that tools that need to look at commits to clean up a history with such broken commits can still get at the structural data (i.e. the parents chain and the tree object).

We were relying on the ability to mmap() 20 bytes beyond the current end of the file, then later fill in those bytes with a future write() call, then read them through the previously obtained mmap() address. This isn't always true with some implementations of NFS, but it is especially not true with our NO_MMAP=YesPlease build time option used on some platforms. If fast-import was built with NO_MMAP=YesPlease we used the malloc()+pread() emulation and the subsequent write() call does not update the trailing 20 bytes of a previously obtained "mmap()" (aka malloc'd) address. Under NO_MMAP that behavior causes unpack_entry() in sha1_file.c to be unable to read an object header (or data) that has been unlucky enough to be written to the packfile at a location such that it is in the trailing 20 bytes of a window previously opened on that same packfile. This bug has gone unnoticed for a very long time as it is highly data dependent. Not only does the object have to be placed at the right position, but it also needs to be positioned behind some other object that has been accessed due to a branch cache invalidation. In other words the stars had to align just right, and if you did run into this bug you probably should also have purchased a lottery ticket. Fortunately the workaround is a lot easier than the bug explanation. Before we allow unpack_entry() to read data from a pack window that has also (possibly) been modified through write() we force all existing windows on that packfile to be closed. By closing the windows we ensure that any new access via the emulated mmap() will reread the packfile, updating to the current file content. This comes at a slight performance degredation as we cannot reuse previously cached windows when we update the packfile. But it is a fairly minor difference as the window closes happen at only two points: - When the packfile is finalized and its .idx is generated: At this stage we are getting ready to update the refs and any data access into the packfile is going to be random, and is going after only the branch tips (to ensure they are valid). Our existing windows (if any) are not likely to be positioned at useful locations to access those final tip commits so we probably were closing them before anyway. - When the branch cache missed and we need to reload: At this point fast-import is getting change commands for the next commit and it needs to go re-read a tree object it previously had written out to the packfile. What windows we had (if any) are not likely to cover the tree in question so we probably were closing them before anyway. We do try to avoid unnecessarily closing windows in the second case by checking to see if the packfile size has increased since the last time we called unpack_entry() on that packfile. If the size has not changed then we have not written additional data, and any existing window is still vaild. This nicely handles the cases where fast-import is going through a branch cache reload and needs to read many trees at once. During such an event we are not likely to be updating the packfile so we do not cycle the windows between reads. With this change in place t9301-fast-export.sh (which was broken by c3b0dec509fe136c5417422f31898b5a4e2d5e02) finally works again. Signed-off-by: Shawn O.

d6cf61b close_lock_file(): new function in the lockfile API The lockfile API is a handy way to obtain a file that is cleaned up if you die(). But sometimes you would need this sequence to work: 1. hold_lock_file_for_update() to get a file descriptor for writing; 2. write the contents out, without being able to decide if the results should be committed or rolled back; 3. do something else that makes the decision --- and this "something else" needs the lockfile not to have an open file descriptor for writing (e.g. Windows do not want a open file to be renamed); 4. call commit_lock_file() or rollback_lock_file() as appropriately. This adds close_lock_file() you can call between step 2 and 3 in the above sequence. Signed-off-by: Junio C Hamano <gitster@pobox.com> 16 January 2008, 23:35:03 UTC

c3b0dec Be more careful about updating refs This makes write_ref_sha1() more careful: it actually checks the SHA1 of the ref it is updating, and refuses to update a ref with an object that it cannot find. Perhaps more importantly, it also refuses to update a branch head with a non-commit object. I don't quite know *how* the stable series maintainers were able to corrupt their repository to have a HEAD that pointed to a tag rather than a commit object, but they did. Which results in a totally broken repository that cannot be cloned or committed on. So make it harder for people to shoot themselves in the foot like that. The test t1400-update-ref.sh is fixed at the same time, as it assumed that the commands involved in the particular test would not care about corrupted repositories whose refs point at nonexistant bogus objects.

2862419 treat any file with NUL as binary There are two heuristics in Git to detect whether a file is binary or text. One in xdiff-interface.c (which is taken from GNU diff) relies on existence of the NUL byte at the beginning. However, convert.c used a different heuristic, which relied on the percent of non-printable symbols (less than 1% for text files). Due to differences in detection whether a file is binary or not, it was possible that a file that diff treats as binary could be treated as text by CRLF conversion. This is very confusing for a user who sees that 'git diff' shows the file as binary expects it to be added as binary. This patch makes is_binary to consider any file that contains at least one NUL character as binary, to ensure that the heuristics used for CRLF conversion is tighter than what is used by diff.

In such cases the core Git tools allow users to initialize a new repository by simply running `git init` at the desired root level directory. We need to allow the same situation in git-gui; if the user is trying to make a new repository we should let them do that to any location they chose. If the directory already exists and already has files contained within it we still should allow the user to create a repository there.

4439751 git-commit: fix double close(2) that can close a wrong file descriptor The codepath to prepare index files for the temporary and next index file was closing file descriptor it obtained from the lockfile API by hand, without letting the API know that the fd should not be doubly closed. This is not usually a problem (except it may get EBADFD) but if we opened another fd for an entirely unrelated purpose (say, an fd used to mmap a packfile) between the time we close the fd to the index file and the time we commit or rollback the lockfile (causing it to also try closing the recorded fd), the lockfile API will close an incorrect file descriptor that is still used for an entirely unrelated purpose. There's four close(fd) calls in prepare_index() and they're all incorrect. The open fd's are cleaned up in rollback_index_files() and shouldn't be closed manually. The patch below gets rid of the extra close() calls and should fix the problem. Signed-off-by: Junio C Hamano <gitster@pobox.com> 16 January 2008, 01:33:53 UTC

e87e22d Revert "builtin-commit.c: remove useless check added by faulty cut and paste" This reverts commit 16335fdd7ace78a8285ba25fd7a81177a48e7c9b. We are calling overlay_tree_on_cache() which does use CE_UPDATE flag to mark duplicated entries, which is the same as the codepath in git-ls-files with its --with-tree option. Because the pathname ce->name is given to path_list_insert() which does not allow duplicates, there is no breakage either way from the correctness point of view in this codepath, unlike the one in ls-files. But avoiding unnecessary processing with a single bit check is certainly better. 14 January 2008, 21:54:24 UTC

98fa5b6 git-svn: handle leading/trailing whitespace from svnsync revprops Repositories generated by svnsync cannot be relied on to have properly set revprops without newlines in UUIDs and URLs. There may be broken versions of svnsync out there that append extra newlines to UUIDs, or the revprops could've been changed by repository administrators at any time, too. At least one repository we've come across has an embedded newline erroneously set in the svnsync-uuid prop. This is bad because the trailing newline is taken as another record by the Git.pm library, and the wantarray detection causes tmp_config() to return an array with an empty-but-existing second element. We will now strip leading and trailing whitespace both before setting and after reading the uuid and url for svnsync values. We will also force tmp_config to return a single scalar when reading existing values. SVN UUIDs should never have whitespace in them, and SVN repository URLs should be URI-escaped, so neither of those values we ever see in git-svn should actually have whitespace in them.
