2009-04-17Fix buffer overflow in config parserLibravatar Thomas Jarosch2-2/+9
When interpreting a config value, the config parser reads in 1+ space character(s) and puts -one- space character in the buffer as soon as the first non-space character is encountered (if not inside quotes). Unfortunately the buffer size check lacks the extra space character which gets inserted at the next non-space character, resulting in a crash with a specially crafted config entry. The unit test now uses Java to compile a platform independent .NET framework to output the test string in C# :o) Read: Thanks to Johannes Sixt for the correct printf call which replaces the perl invocation.

There's another easy 5% or so for the built-in object walker: once we've created the hash from the name, the name isn't interesting any more, and so something trivial like this can help a bit. Does it matter? Probably not on its own. But a few more memory saving tricks and it might all make a difference. Linus Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-08process_{tree,blob}: Remove useless xstrdup callsLibravatar Björn Steinbrink2-3/+0
The name of the processed object was duplicated for passing it to add_object(), but that already calls path_name, which allocates a new string anyway. So the memory allocated by the xstrdup calls just went nowhere, leaking memory.

2009-03-24avoid possible overflow in delta size filtering computationLibravatar Nicolas Pitre1-1/+1
On a 32-bit system, the maximum possible size for an object is less than 4GB, while 64-bit systems may cope with larger objects. Due to this limitation, variables holding object sizes are using an unsigned long type (32 bits on 32-bit systems, or 64 bits on 64-bit systems). When large objects are encountered, and/or people play with large delta depth values, it is possible for the maximum allowed delta size computation to overflow, especially on a 32-bit system. When this occurs, surviving result bits may represent a value much smaller than what it is supposed to be, or even zero. This prevents some objects from being deltified although they do get deltified when a smaller depth limit is used. Fix this by always performing a 64-bit multiplication.

2009-02-27bisect: fix another instance of eval'ed stringLibravatar Christian Couder1-1/+7
When there is nothing to be skipped, the output from rev-list --bisect-vars was eval'ed without first being strung together with &&; this is probably not a problem as it is much less likely to be a bad input than the list handcrafted by the filter_skip function, but it still is a good discipline.

2009-02-27bisect: fix quoting TRIED revs when "bad" commit is also "skip"pedLibravatar Christian Couder2-35/+66
When the "bad" commit was also "skip"ped and when more than one commit was skipped, the "filter_skipped" function would have printed something like: bisect_rev=<hash1>|<hash2> (where <hash1> and <hash2> are hexadecimal sha1 hashes) and this would have been evaled later as piping "bisect_rev=<hash1>" into "<hash2>", which would have failed. So this patch makes the "filter_skipped" function properly quote what it outputs, so that it will print something like: bisect_rev='<hash1>|<hash2>' which will be properly evaled later. The caller was not stopping properly because the scriptlet this function returned to be evaled was not strung together with && and because of this, an error in an earlier part of the output was simply ignored. A test case is added to the test suite. And while at it, we also initialize the VARS, FOUND and TRIED variables, so that we protect ourselves from environment variables the user may have with these names.

2009-02-12Support "\" in non-wildcard exclusion entriesLibravatar Finn Arne Gangstad2-2/+9
"\" was treated differently in exclude rules depending on whether a wildcard match was done. For wildcard rules, "\" was de-escaped in fnmatch, but this was not done for other rules since they used strcmp instead. A file named "#foo" would not be excluded by "\#foo", but would be excluded by "\#foo*". We now treat all rules with "\" as wildcard rules. Another solution could be to de-escape all non-wildcard rules as we read them, but we would have to do the de-escaping exactly as fnmatch does it to avoid inconsistencies.

2009-02-11Make repack less likely to corrupt repositoryLibravatar Junio C Hamano1-20/+67
Some platforms refuse to rename a file that is open. When repacking an already packed repository without adding any new object, the resulting pack will contain the same set of objects as an existing pack, and on such platforms, a newly created packfile cannot replace the existing one. The logic detected this issue but did not try hard enough to recover from it. Especially because the files that needs renaming come in pairs, there potentially are different failure modes that one can be renamed but the others cannot. Asking manual recovery to end users were error prone. This patch tries to make it more robust by first making sure all the existing files that need to be renamed have been renamed before continuing, and attempts to roll back if some failed to rename. This is based on an initial patch by Robin Rosenberg. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-02-11Clear the delta base cache if a pack is rebuiltLibravatar Shawn O. Pearce1-0/+1
There is some risk that re-opening a regenerated pack file with different offsets could leave stale entries within the delta base cache that could be matched up against other objects using the same "struct packed_git*" and pack offset. Throwing away the entire delta base cache in this case is safer, as we don't have to worry about a recycled "struct packed_git*" matching to the wrong base object, resulting in delta apply errors while unpacking an object.

The parameter n of unpack_callback() can have a value of up to MAX_UNPACK_TREES. The check at the top of unpack_trees() (its only (indirect) caller) makes sure it cannot exceed this limit. unpack_callback() passes it and the array src to unpack_nondirectories(), which has this loop: for (i = 0; i < n; i++) { /* ... */ src[i + o->merge] = o->df_conflict_entry; o->merge can be 0 or 1, so unpack_nondirectories() potentially accesses the array src at index MAX_UNPACK_TREES.

2009-01-27diff.c: output correct index lines for a split diffLibravatar Junio C Hamano2-66/+98
A patch that changes the filetype (e.g. regular file to symlink) of a path must be split into a deletion event followed by a creation event, which means that we need to have two independent metainfo lines for each. However, the code reused the single set of metainfo lines. As the blob object names recorded on the index lines are usually not used nor validated on the receiving end, this is not an issue with normal use of the resulting patch. However, when accepting a binary patch to delete a blob, git-apply verified that the postimage blob object name on the index line is 0{40}, hence a patch that deletes a regular file blob that records binary contents to create a blob with different filetype (e.g. a symbolic link) failed to apply. "git am -3" also uses the blob object names recorded on the index line, so it would also misbehave when synthesizing a preimage tree. This moves the code to generate metainfo lines around, so that two independent sets of metainfo lines are used for the split halves. Additional tests by Jeff King.
