2007-09-18fast-import optimization:Libravatar Pierre Habouzit1-32/+20
Now that cmd_data acts on a strbuf, make last_object stashed buffer be a strbuf as well. On new stash, don't free the last stashed buffer, rather swap it with the one you will stash, this way, callers of store_object can act on static strbufs, and at some point, fast-import won't allocate new memory for objects buffers.

2007-09-18Drop strbuf's 'eof' marker, and make read_line a first class citizen.Libravatar Pierre Habouzit7-41/+39
read_line is now strbuf_getline, and is a first class citizen, it returns 0 when reading a line worked, EOF else. The ->eof marker was used non-locally by fast-import.c, mimic the same behaviour using a static int in "read_next_command", that now returns -1 on EOF, and avoids to call strbuf_getline when it's in EOF state. Also no longer automagically strbuf_release the buffer, it's counter intuitive and breaks fast-import in a very subtle way. Note: being at EOF implies that command_buf.len == 0.

2007-09-16Rewrite convert_to_{git,working_tree} to use strbuf's.Libravatar Pierre Habouzit7-317/+240
* Now, those functions take an "out" strbuf argument, where they store their result if any. In that case, it also returns 1, else it returns 0. * those functions support "in place" editing, in the sense that it's OK to call them this way: convert_to_git(path, sb->buf, sb->len, sb); When doable, conversions are done in place for real, else the strbuf content is just replaced with the new one, transparentely for the caller. If you want to create a new filter working this way, being the accumulation of filter1, filter2, ... filtern, then your meta_filter would be: int meta_filter(..., const char *src, size_t len, struct strbuf *sb) { int ret = 0; ret |= filter1(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } ret |= filter2(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } .... return ret | filtern(..., src, len, sb); } That's why subfilters the convert_to_* functions called were also rewritten to work this way.

2007-09-13archive: fix subst file generationLibravatar René Scharfe2-9/+10
Before the strbuf conversion, result was a char pointer. The if statement checked for it being not NULL, which meant that no "$Format:...$" string had been found and no replacement had to be made. format_subst() returned NULL in that case -- the caller then simply kept the original file content, as it was unaffected by the expansion. The length of the string being 0 is not the same as the string being NULL (expansion to an empty string vs. no expansion at all), so checking result.len != 0 is not a full replacement for the old NULL check. However, I doubt the subtle optimization explained above resulted in a notable speed-up anyway. Simplify the code and add the tail of the file to the expanded string unconditionally.

2007-09-10Rework pretty_print_commit to use strbufs instead of custom buffers.Libravatar Pierre Habouzit8-299/+191
Also remove the "len" parameter, as: (1) it was used as a max boundary, and every caller used ~0u (2) we check for final NUL no matter what, so it doesn't help for speed. As a result most of the pp_* function takes 3 arguments less, and we need a lot less local variables, this makes the code way more readable, and easier to extend if needed.

* Add strbuf_rtrim to remove trailing spaces. * Add strbuf_insert to insert data at a given position. * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final \0 so the overflow test for snprintf is the strict comparison. This is not critical as the growth mechanism chosen will always allocate _more_ memory than asked, so the second test will not fail. It's some kind of miracle though. * Add size extension hints for strbuf_init and strbuf_read. If 0, default applies, else: + initial buffer has the given size for strbuf_init. + first growth checks it has at least this size rather than the default 8192.

2007-09-10Make --no-thin the default in git-push to save server resourcesLibravatar Shawn O. Pearce1-1/+1
1) pushes happen less often than fetches, so the bandwidth saving is much less visible in that case overall. 2) thin packs have to be complemented with missing delta bases to be valid, so many received thin packs will take more disk space. 3) the bother of repacking should be distributed amongst "clients" i.e. fetchers and pushers as much as possible, and not the server being fetched or pushed, to keep disk and CPU usage low on the server. This is why a fetch should get thin packs but a push should not. Both Nico and I have been assuming that --no-thin was the default behavior of git-push ever since Nico introduced --fix-thin into the index-pack process, which allowed fetch and receive-pack to avoid exploding packfiles received during transfer. This patch finally makes it so. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-09-09git-tag -s must fail if gpg cannot sign the tag.Libravatar Carlos Rica2-4/+21
Most of this patch code and message was written by Shawn O. Pearce. I made some tests to know what the problem was, and then I changed the code related with the SIGPIPE signal. If the user has misconfigured `user.signingkey` in their .git/config or just doesn't have any secret keys on their keyring and they ask for a signed tag with `git tag -s` we better make sure the resulting tag was actually signed by gpg. Prior versions of builtin git-tag allowed this failure to slip by without error as they were not checking the return value of the finish_command() so they did not notice when gpg exited with an error exit status. They also did not fail if gpg produced an empty output or if read_in_full received an error from the read system call while trying to read the pipe back from gpg. Finally, we did not actually honor any return value from the do_sign function as it returns ssize_t but was being stored into an unsigned long. This caused the compiler to optimize out the die condition, allowing git-tag to continue along and create the tag object. However, when gpg gets a wrong username, it exits before any read was done and then the writing process receives SIGPIPE and program is terminated. By ignoring this signal, anyway, the function write_or_die gets EPIPE from write_in_full and exits returning 0 to the system without a message. Here we better call to write_in_full directly so we can fail printing a message and return safely to the caller. With these issues fixed `git-tag -s` will now fail to create the tag and will report a non-zero exit status to its caller, thereby allowing automated helper scripts to detect (and recover from) failure if gpg is not working properly.

We have a workaround for the reparent function not working correctly on the SVN native protocol servers. This workaround opens a new connection (SVN::Ra object) to the new URL/directory. Since libsvn appears limited to only supporting one connection at a time, this workaround invalidates the Git::SVN::Ra object that is $self inside gs_fetch_loop_common(). So we need to restart that connection once all the fetching is done for each loop iteration to be able to run get_log() successfully.

2007-09-06Rework strbuf API and semantics.Libravatar Pierre Habouzit5-28/+180
The gory details are explained in strbuf.h. The change of semantics this patch enforces is that the embeded buffer has always a '\0' character after its last byte, to always make it a C-string. The offs-by-one changes are all related to that very change. A strbuf can be used to store byte arrays, or as an extended string library. The `buf' member can be passed to any C legacy string function, because strbuf operations always ensure there is a terminating \0 at the end of the buffer, not accounted in the `len' field of the structure. A strbuf can be used to generate a string/buffer whose final size is not really known, and then "strbuf_detach" can be used to get the built buffer, and keep the wrapping "strbuf" structure usable for further work again. Other interesting feature: strbuf_grow(sb, size) ensure that there is enough allocated space in `sb' to put `size' new octets of data in the buffer. It helps avoiding reallocating data for nothing when the problem the strbuf helps to solve has a known typical size.

memmem() is a nice GNU extension for searching a length limited string in another one. This compat version is based on the version found in glibc 2.2 (GPL 2); I only removed the optimization of checking the first char by hand, and generally tried to keep the code simple. We can add it back if memcmp shows up high in a profile, but for now I prefer to keep it (almost trivially) simple. Since I don't really know which platforms beside those with a glibc have their own memmem(), I used a heuristic: if NO_STRCASESTR is set, then NO_MEMMEM is set, too.

Recently I found that doing a sequence like the following: git-new-workdir a b ... git-new-workdir a b by accident will cause a (and now also b) to have an infinite cycle in its refs directory. This is caused by git-new-workdir trying to create the "refs" symlink over again, only during the second time it is being created within a's refs directory and is now also pointing back at a's refs. This causes confusion in git as suddenly branches are named things like "refs/refs/refs/refs/refs/refs/refs/heads/foo" instead of the more commonly accepted "refs/heads/foo". Plenty of commands start to see ambiguous ref names and others just take ages to compute. git-clone has the same safety check, so git-new-workdir should behave just like it. Signed-off-by: Shawn O.

When the preimage we are patching is shorter than what the patch text expects, we tried to match the buffer contents at the "original" line with the fragment in full, without checking we have enough data to match in the preimage. This caused the size of a later memmove() to wrap around and attempt to scribble almost the entire address space. Not good. The code that follows the part this patch touches tries to match the fragment with line offsets. Curiously, that code does not have the problem --- it guards against reading past the end of the preimage. Signed-off-by: Junio C Hamano <gitster@pobox.com>
