The "graph" API used in "git log --graph" miscounted the number of output columns consumed so far when drawing a padding line, which has been fixed; this did not affect any existing code as nobody tried to write anything after the padding on such a line, though. * jk/graph-padding-fix: graph: fix extra spaces in graph_padding_line

2016-10-03ref-filter: strip format option after a field name only once while parsingLibravatar SZEDER Gábor1-11/+11
When parse_ref_filter_atom() iterates over a list of valid atoms to check that a field name is one of them, it has to strip the optional colon-separated format option suffix that might follow the field name. However, it does so inside the loop, i.e. it performs the exact same stripping over and over again. Move stripping the format option suffix out of that loop, so it's only performed once for each parsed field name.

Some codepaths in "git diff" used regexec(3) on a buffer that was mmap(2)ed, which may not have a terminating NUL, leading to a read beyond the end of the mapped region.

"git checkout <word>" does not follow the usual disambiguation rules when the <word> can be both a rev and a path, to allow checking out a branch 'foo' in a project that happens to have a file 'foo' in the working tree without having to disambiguate.

Even when "git pull --rebase=preserve" (and the underlying "git rebase --preserve") can complete without creating any new commit (i.e. fast-forwards), it still insisted on having a usable ident information (read: user.email is set correctly), which was less than nice.

2016-09-29graph: fix extra spaces in graph_padding_lineLibravatar Jeff King1-4/+12
The graph_padding_line() function outputs a series of "|" columns, and then pads with spaces to graph->width by calling graph_pad_horizontally(). However, we tell the latter that we wrote graph->num_columns characters, which is not true; we also needed spaces between the columns. Let's keep a count of how many characters we've written, which is what all the other callers of graph_pad_horizontally() do. Without this, any output that is written at the end of a padding line will be bumped out by at least an extra graph->num_columns spaces. Presumably nobody ever noticed the bug because there's no code path that actually writes to the end of a padding line.

2016-09-25add COPY_ARRAYLibravatar René Scharfe1-0/+8
Add COPY_ARRAY, a safe and convenient helper for copying arrays, complementing ALLOC_ARRAY and REALLOC_ARRAY. Users just specify source, destination and the number of elements; the size of an element is inferred automatically. It checks if the multiplication of size and element count overflows. The inferred size is passed first to st_mult, which allows the division there to be done at compilation time. As a basic type safety check it makes sure the sizes of source and destination elements are the same. That's evaluated at compilation time as well. COPY_ARRAY is safe to use with NULL as source pointer iff 0 elements are to be copied. That convention is used in some cases for initializing arrays. Raw memcpy(3) does not support it -- compilers are allowed to assume that only valid pointers are passed to it and can optimize away NULL checks after such a call.

2016-09-23ident: handle NULL ai_canonnameLibravatar Jeff King1-1/+1
We call getaddrinfo() to try to convert a short hostname into a fully-qualified one (to use it as an email domain). If there isn't a canonical name, getaddrinfo() will generally return either a NULL addrinfo list, or one in which ai->ai_canonname is a copy of the original name. However, if the result of gethostname() looks like an IP address, then getaddrinfo() behaves differently on some systems. On OS X, it will return a "struct addrinfo" with a NULL ai_canonname, and we segfault feeding it to strchr(). This is hard to test reliably because it involves not only a system where we we have to fallback to gethostname() to come up with an ident, but also where the hostname is a number with no dots. But I was able to replicate the bug by faking a hostname, like: diff --git a/ident.c b/ident.c index e20a772..b790d28 100644 --- a/ident.c +++ b/ident.c @@ -128,6 +128,7 @@ static void add_domainname(struct strbuf *out, int *is_bogus) *is_bogus = 1; return; } + xsnprintf(buf, sizeof(buf), "1"); if (strchr(buf, '.')) strbuf_addstr(out, buf); else if (canonical_name(buf, out) < 0) { and running "git var GIT_AUTHOR_IDENT" on an OS X system. Before this patch it segfaults, and after we correctly complain of the bogus "user@1.(none)" address (though this bogus address would be suitable for non-object uses like writing reflogs).

2016-09-21t3700-add: do not check working tree file mode without POSIXPERMLibravatar Johannes Sixt1-4/+2
A recently introduced test checks the result of 'git status' after setting the executable bit on a file. This check does not yield the expected result when the filesystem does not support the executable bit. What we care about is that a file added with "--chmod=+x" has executable bit in the index and that "--chmod=+x" (or any other options for that matter) does not muck with working tree files. The former is tested by other existing tests, so let's check the latter more explicitly and only under POSIXPERM prerequisite.

2016-09-21regex: use regexec_buf()Libravatar Johannes Schindelin5-33/+17
The new regexec_buf() function operates on buffers with an explicitly specified length, rather than NUL-terminated strings. We need to use this function whenever the buffer we want to pass to regexec(3) may have been mmap(2)ed (and is hence not NUL-terminated). Note: the original motivation for this patch was to fix a bug where `git diff -G <regex>` would crash. This patch converts more callers, though, some of which allocated to construct NUL-terminated strings, or worse, modified buffers to temporarily insert NULs while calling regexec(3). By converting them to use regexec_buf(), the code has become much cleaner. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-09-21regex: add regexec_buf() that can work on a non NUL-terminated stringLibravatar Johannes Schindelin2-1/+15
We just introduced a test that demonstrates that our sloppy use of regexec() on a mmap()ed area can result in incorrect results or even hard crashes. So what we need to fix this is a function that calls regexec() on a length-delimited, rather than a NUL-terminated, string. Happily, there is an extension to regexec() introduced by the NetBSD project and present in all major regex implementation including Linux', MacOSX' and the one Git includes in compat/regex/: by using the (non-POSIX) REG_STARTEND flag, it is possible to tell the regexec() function that it should only look at the offsets between pmatch[0].rm_so and pmatch[0].rm_eo. That is exactly what we need. Since support for REG_STARTEND is so widespread by now, let's just introduce a helper function that always uses it, and tell people on a platform whose regex library does not support it to use the one from our compat/regex/ directory.

2016-09-21regex: -G<pattern> feeds a non NUL-terminated string to regexec() and failsLibravatar Johannes Schindelin1-0/+22
When our pickaxe code feeds file contents to regexec(), it implicitly assumes that the file contents are read into implicitly NUL-terminated buffers (i.e. that we overallocate by 1, appending a single '\0'). This is not so. In particular when the file contents are simply mmap()ed, we can be virtually certain that the buffer is preceding uninitialized bytes, or invalid pages. Note that the test we add here is known to be flakey: we simply cannot know whether the byte following the mmap()ed ones is a NUL or not. Typically, on Linux the test passes. On Windows, it fails virtually every time due to an access violation (that's a segmentation fault for you Unix-y people out there). And Windows would be correct: the regexec() call wants to operate on a regular, NUL-terminated string, there is no NUL in the mmap()ed memory range, and it is undefined whether the next byte is even legal to access. When run with --valgrind it demonstrates quite clearly the breakage, of course. Being marked with `test_expect_failure`, this test will sometimes be declare "TODO fixed", even if it only passes by mistake. This test case represents a Minimal, Complete and Verifiable Example of a breakage reported by Chris Sidi.
