2009-10-14sha1_file: Fix infinite loop when pack is corruptedLibravatar Shawn O. Pearce2-0/+13
Some types of corruption to a pack may confuse the deflate stream which stores an object. In Andy's reported case a 36 byte region of the pack was overwritten, leading to what appeared to be a valid deflate stream that was trying to produce a result larger than our allocated output buffer could accept. Z_BUF_ERROR is returned from inflate() if either the input buffer needs more input bytes, or the output buffer has run out of space. Previously we only considered the former case, as it meant we needed to move the stream's input buffer to the next window in the pack. We now abort the loop if inflate() returns Z_BUF_ERROR without consuming the entire input buffer it was given, or has filled the entire output buffer but has not yet returned Z_STREAM_END. Either state is a clear indicator that this loop is not working as expected, and should not continue. This problem cannot occur with loose objects as we open the entire loose object as a single buffer and treat Z_BUF_ERROR as an error.

2009-10-14clone: Supply the right commit hash to post-checkout when -b is usedLibravatar Björn Steinbrink2-1/+3
When we use -b <branch>, we may checkout something else than what the remote's HEAD references, but we still used remote_head to supply the new ref value to the post-checkout hook, which is wrong. So instead of using remote_head to find the value to be passed to the post-checkout hook, we have to use our_head_points_at, which is always correctly setup, even if -b is not used. This also fixes a segfault when "clone -b <branch>" is used with a remote repo that doesn't have a valid HEAD, as in such a case remote_head is NULL, but we still tried to access it.

2009-10-12bash completion: complete refs for git-grepLibravatar Thomas Rast1-1/+2
Before the --, always attempt ref completion. This helps with entering the <treeish> arguments to git-grep. As a bonus, you can work around git-grep's current lack of --all by hitting M-*, ugly as the resulting command line may be. Strictly speaking, completing the regular expression argument (or option argument) makes no sense. However, we cannot prevent _all_ completion (it will fall back to filenames), so we dispense with any additional complication to detect whether the user still has to enter a regular expression.

2009-10-09Documentation: clone: clarify discussion of initial branchLibravatar Jonathan Nieder1-2/+3
When saying the initial branch is equal to the currently active remote branch, it is probably intended that the branch heads point to the same commit. Maybe it would be more useful to a new user to emphasize that the tree contents and history are the same. More important, probably, is that this new branch is set up so that "git pull" merges changes from the corresponding remote branch. The next paragraph addresses that directly. What the reader needs to know to begin with is that (1) the initial branch is your own; if you do not pull, it won't get updated, and that (2) the initial branch starts out at the same commit as the upstream.

2009-10-09completion: fix alias listings with newlinesLibravatar Stephen Boyd1-2/+6
Aliases with newlines have been a problem since commit 56fc25f (Bash completion support for remotes in .git/config., 2006-11-05). The chance of the problem occurring has been slim at best, until commit 518ef8f (completion: Replace config --list with --get-regexp, 2009-09-11) removed the case statement introduced by commit 56fc25f. Before removing the case statement, most aliases with newlines would work unless they were specially crafted as follows [alias] foo = "log -1 --pretty='format:%s\nalias.error=broken'" After removing the case statement, a more benign alias like [alias] whowhat = "log -1 --pretty='format:%an <%ae>\n%s'" wont-complete = ... would cause the completion to break badly. For now, revert the removal of the case statement until someone comes up with a better way to get keys from git-config. Signed-off-by: Stephen Boyd <bebarino@gmail.com> Acked-by: Shawn O.

After commit 511a3fc (wrap git's main usage string., 2009-09-12), the bash completion for git commands includes COMMAND and [ARGS] when it shouldn't. Fix this by grepping more strictly for a line with git commands. It's doubtful whether git will ever have commands starting with anything besides numbers and letters so this should be fine.

2009-10-09pull: improve advice for unconfigured error caseLibravatar Jeff King1-4/+12
There are several reasons a git-pull invocation might not have anything marked for merge: 1. We're not on a branch, so there is no branch configuration. 2. We're on a branch, but there is no configuration for this branch. 3. We fetched from the configured remote, but the configured branch to merge didn't get fetched (either it doesn't exist, or wasn't part of the fetch refspec). 4. We fetched from the non-default remote, but didn't specify a branch to merge. We can't use the configured one because it applies to the default remote. 5. We fetched from a specified remote, and a refspec was given, but it ended up not fetching anything (this is actually hard to do; if the refspec points to a remote branch and it doesn't exist, then fetch will fail and we never make it to this code path. But if you provide a wildcard refspec like refs/bogus/*:refs/remotes/origin/* then you can see this failure). We have handled (1) and (2) for some time. Recently, commit a6dbf88 added code to handle case (3). This patch handles cases (4) and (5), which previously just fell under other cases, producing a confusing message. While we're at it, let's rewrap the text for case (3), which looks terribly ugly as it is. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-10-08Makefile: add a note about the NO_MMAP setting on IRIX and IRIX64Libravatar Brandon Casey1-0/+12
When git is compiled with the MIPSpro 7.4.4m compiler, and NO_PTHREADS is set, and NO_MMAP is _not_ set, then git segfaults when trying to access the first entry in a reflog. If NO_PTHREADS is not set (which implies that the pthread library is linked in), or NO_MMAP _is_ set, then the segfault is not encountered. The conservative choice has been made to set NO_MMAP in the Makefile to avoid this flaw. The GNU C compiler does not produce this behavior. The segfault happens in refs.c:read_ref_at(). The mmap succeeds, and the loop is executed properly until rec is rewound into the first line (reflog entry) of the file. The segfault is caught by test 28 of t1400-update-ref.sh which fails when 'git rev-parse --verify "master@{May 25 2005}"' is called. So, add a comment in the Makefile to describe why NO_MMAP is set and as a hint to those who may be interested in unsetting it.

When ls-files was called with -i but no exclude pattern, it was calling fprintf(stderr, "...", NULL) and then exiting. On Solaris, passing NULL into fprintf was causing a segfault. On glibc systems, it was simply producing incorrect output (eg: "(null)": ...). The NULL pointer was a result of argv[0] not being preserved by the option parser. Instead of requesting that the option parser preserve argv[0], use die() with a constant string.

2009-10-08Fix the exit code of MSVC build scripts on cygwinLibravatar Ramsay Jones2-2/+2
During an MSVC build on cygwin, the make program did not notice when the compiler or linker exited with an error. This was caused by the scripts exiting with the value returned by system() directly. On POSIX-like systems, such as cygwin, the return value of system() has the exit code of the executed command encoded in the first byte (ie the value is shifted up by 8 bits). This allows the bottom 7 bits to contain the signal number of a terminated process, while the eighth bit indicates whether a core-dump was produced. (A value of -1 indicates that the command failed to execute.) The make program, however, expects the exit code to be encoded in the bottom byte. Futhermore, it apparently masks off and ignores anything in the upper bytes. However, these scripts are (naturally) intended to be used on the windows platform, where we can not assume POSIX-like semantics from a perl implementation (eg ActiveState). So, in general, we can not assume that shifting the return value right by eight will get us the exit code. In order to improve portability, we assume that a zero return from system() indicates success, whereas anything else indicates failure. Since we don't need to know the exact exit code from the compiler or linker, we simply exit with 0 (success) or 1 (failure).

2009-10-08Fix MSVC build on cygwinLibravatar Ramsay Jones1-1/+1
In the MSVC section of the Makefile, BASIC_CFLAGS is set to a value which contains the string "-DWIN32-D_CONSOLE". This results in a (single) malformed -Define being passed to the compiler. At least on my cygwin installation, the msvc compiler seems to ignore this parameter, without issuing an error or warning, and results in the WIN32 and _CONSOLE macros being undefined. This breaks the build. In order to fix the build, we simply insert a space between the two -Define parameters, "-DWIN32" and "-D_CONSOLE", as originally intended.
