The description of crlf attribute incorrectly said that "-crlf" means binary. It is true that for binary files you would want "-crlf", but that is not the same thing.

2008-08-30git-apply: Loosen "match_beginning" logicLibravatar Junio C Hamano2-4/+16
Even after a handfle attempts, match_beginning logic still has corner cases: 1bf1a85 (apply: treat EOF as proper context., 2006-05-23) 65aadb9 (apply: force matching at the beginning., 2006-05-24) 4be6096 (apply --unidiff-zero: loosen sanity checks ..., 2006-09-17) ee5a317 (Fix "git apply" to correctly enforce "match ..., 2008-04-06) This is a tricky piece of code. We still incorrectly enforce "match_beginning" for -U0 matches. I noticed this while trying out an example sequence from Clemens Buchacher: $ echo a >victim $ git add victim $ echo b >>victim $ git diff -U0 >patch $ cat patch diff --git i/victim w/victim index 7898192..422c2b7 100644 --- i/victim +++ w/victim @@ -1,0 +2 @@ a +b $ git apply --cached --unidiff-zero <patch $ git show :victim b a The change inserts a new line before the second line, but we insist it to be applied at the beginning. As the result, the code refuses to apply it at the original offset, and we end up adding the line at the beginning. Updates to the test script are by Clemens Buchacher.

2008-08-29make git-shell paranoid about closed stdin/stdout/stderrLibravatar Paolo Bonzini1-0/+13
It is in general unsafe to start a program with one or more of file descriptors 0/1/2 closed. Karl Chen for example noticed that stat_command does this in order to rename a pipe file descriptor to 0: dup2(from, 0); close(from); ... but if stdin was closed (for example) from == 0, so that dup2(0, 0); close(0); just ends up closing the pipe. Another extremely rare but nasty problem would occur if an "important" file ends up in file descriptor 2, and is corrupted by a call to die(). Fixing this in git was considered to be overkill, so this patch works around it only for git-shell. The fix is simply to open all the "low" descriptors to /dev/null in main.

2008-08-29Fix '--dirstat' with cross-directory renamingLibravatar Linus Torvalds1-0/+8
The dirstat code depends on the fact that we always generate diffs with the names sorted, since it then just does a single-pass walk-over of the sorted list of names and how many changes there were. The sorting means that all files are nicely grouped by directory. That all works fine. Except when we have rename detection, and suddenly the nicely sorted list of pathnames isn't all that sorted at all. And now the single-pass dirstat walk gets all confused, and you can get results like this: [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5 3.0% arch/powerpc/configs/ 6.8% arch/arm/configs/ 2.7% arch/powerpc/configs/ 4.2% arch/arm/configs/ 5.6% arch/powerpc/configs/ 8.4% arch/arm/configs/ 5.5% arch/powerpc/configs/ 23.3% arch/arm/configs/ 8.6% arch/powerpc/configs/ 4.0% arch/ 4.4% drivers/usb/musb/ 4.0% drivers/watchdog/ 7.6% drivers/ 3.5% fs/ The trivial fix is to add a sorting pass, fixing it to: [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5 43.0% arch/arm/configs/ 25.5% arch/powerpc/configs/ 5.3% arch/ 4.4% drivers/usb/musb/ 4.0% drivers/watchdog/ 7.6% drivers/ 3.5% fs/ Spot the difference. In case anybody wonders: it's because of a ton of renames from {include/asm-blackfin => arch/blackfin/include/asm} that just totally messed up the file ordering in between arch/arm and arch/powerpc.

2008-08-26Suppress some bash redirection error messagesLibravatar Ramsay Jones3-10/+4
In particular, when testing if the filesystem allows tabs in filenames, bash issues an error something like: ./t4016-diff-quote.sh: pathname with HT: No such file or directory which is caused by the failure of the (stdout) redirection, since the file cannot be created. In order to suppress the error message, you must redirect stderr to /dev/null, *before* the stdout redirection on the command-line. Also, remove a redundant filesystem check from the begining of the t3902-quoted.sh test and standardise the "test skipped" message to 'say' on exit.

2008-08-25Makefile: always provide a fallback when hardlinks failLibravatar Andreas Färber1-11/+11
We make hardlinks from "git" to "git-<cmd>" built-ins and have been careful to avoid cross-device links when linking "git-<cmd>" to gitexecdir. However, we were not prepared to deal with a build directory that is incapable of making hard links within itself. This patch corrects it. Instead of temporarily linking "git" to gitexecdir, directly link "git- add", falling back to "cp". Try hardlinking that as "git-<cmd>", falling back to symlinks or "cp" on error. While at it, avoid 100+ error messages from hardlink failures when we are going to fall back to symlinks or "cp" by redirecting the standard error to /dev/null.

2008-08-24Fix "git log -i --grep"Libravatar Jeff King4-24/+38
This has been broken in v1.6.0 due to the reorganization of the revision option parsing code. The "-i" is completely ignored, but works fine in "git log --grep -i". What happens is that the code for "-i" looks for revs->grep_filter; if it is NULL, we do nothing, since there are no grep filters. But that is obviously not correct, since we want it to influence the later --grep option. Doing it the other way around works, since "-i" just impacts the existing grep_filter option. Instead, we now always initialize the grep_filter member and just fill in options and patterns as we get them. This means that we can no longer check grep_filter for NULL, but instead must check the pattern list to see if we have any actual patterns.

2008-08-23merge: fix numerus bugs around "trivial merge" areaLibravatar Junio C Hamano4-8/+32
The "trivial merge" codepath wants to optimize itself by making an internal call to the read-tree machinery, but it does not read the index before doing so, and the codepath is never exercised. Incidentally, this failure to read the index upfront means that the safety to refuse doing anything when the index is unmerged does not kick in, either. These two problem are fixed by using read_cache_unmerged() that does read the index before checking if it is unmerged at the beginning of cmd_merge(). The primary logic of the merge, however, assumes that the process never reads the index in-core, and the call to write_cache_as_tree() it makes from write_tree_trivial() will always read from the on-disk index that is prepared the strategy back-ends. This assumption is now broken by the above fix. To fix this issue, we now call discard_cache() before calling write_tree_trivial() when it wants to write the on-disk index as a tree. When multiple strategies are tried, their results are evaluated by reading the resulting index and inspecting it. The codepath needs to make a call to read_cache() for each successful strategy, and for that to work, they need to discard_cache() the one read by the previous round. Also the "trivial merge" forgot that the current commit is one of the parents of the resulting commit. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-08-23unpack_trees(): protect the handcrafted in-core index from read_cache()Libravatar Junio C Hamano3-2/+6
unpack_trees() rebuilds the in-core index from scratch by allocating a new structure and finishing it off by copying the built one to the final index. The resulting in-core index is Ok for most use, but read_cache() does not recognize it as such. The function is meant to be no-op if you already have loaded the index, until you call discard_cache(). This change the way read_cache() detects an already initialized in-core index, by introducing an extra bit, and marks the handcrafted in-core index as initialized, to avoid this problem. A better fix in the longer term would be to change the read_cache() API so that it will always discard and re-read from the on-disk index to avoid confusion. But there are higher level API that have relied on the current semantics, and they and their users all need to get converted, which is outside the scope of 'maint' track. An example of such a higher level API is write_cache_as_tree(), which is used by git-write-tree as well as later Porcelains like git-merge, revert and cherry-pick. In the longer term, we should remove read_cache() from there and add one to cmd_write_tree(); other callers expect that the in-core index they prepared is what gets written as a tree so no other change is necessary for this particular codepath. The original version of this patch marked the index by pointing an otherwise wasted malloc'ed memory with o->result.alloc, but this version uses Linus's idea to use a new "initialized" bit, which is conceptually much cleaner.

2008-08-21compat/snprintf.c: handle snprintf's that always return the # chars transmittedLibravatar Brandon Casey1-0/+4
Some platforms provide a horribly broken snprintf. More broken than the platforms that return -1 when there is too little space in the target buffer for the formatted string. Some platforms provide an snprintf which _always_ returns the number of characters transmitted to the buffer, regardless of whether there was enough space or not. IRIX 6.5 is such a platform. IRIX does have a working snprintf(), but it is only provided when _NO_XOPEN5 evaluates to zero, and this only happens if _XOPEN_SOURCE is defined, but definition of _XOPEN_SOURCE prevents inclusion of many other common functions and defines. So it must be avoided. Work around these horribly broken snprintf implementations by detecting an snprintf call which results in the number of transmitted characters exactly equal to the length of our buffer and retrying with a larger buffer just to be safe.

Available strategies are: recursive octopus resolve ours subtree. both on their standard error stream. We can use this to learn what strategies are supported. The sed script is written in such a way that it catches both old and new message styles ("Available" vs "available", and the full stop at the end). It also allows future versions of "git merge" to line-wrap the list of strategies, and add extra comments, like this: $ $HOME/git-snap-v1.6.1/bin/git merge -s help Could not find merge strategy 'help'. Available strategies are: blame recursive octopus resolve ours subtree. Also you have custom strategies: theirs Make sure you spell strategy names correctly.
