* Lift 16kB limit of log message outputJunio C Hamano2007-06-13
| | | | | | | | | | | | | | | | | | | | | Traditionally we had 16kB limit when formatting log messages for output, because it was easier to arrange for the caller to have a reasonably big buffer and pass it down without ever worrying about reallocating. This changes the calling convention of pretty_print_commit() to lift this limit. Instead of the buffer and remaining length, it now takes a pointer to the pointer that points at the allocated buffer, and another pointer to the location that stores the allocated length, and reallocates the buffer as necessary. To support the user format, the error return of interpolate() needed to be changed. It used to return a bool telling "Ok the result fits", or "Sorry, I had to truncate it". Now it returns 0 on success, and returns the size of the buffer it wants in order to fit the whole result. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* General const correctness fixesShawn O. Pearce2007-03-07
| | | | | | | | | | | | | | | | We shouldn't attempt to assign constant strings into char*, as the string is not writable at runtime. Likewise we should always be treating unsigned values as unsigned values, not as signed values. Most of these are very straightforward. The only exception is the (unnecessary) xstrdup/free in builtin-branch.c for the detached head case. Since this is a user-level interactive type program and that particular code path is executed no more than once, I feel that the extra xstrdup call is well worth the easy elimination of this warning.

* prefixcmp(): fix-up leftover strncmp().Junio C Hamano2007-02-20
| | | | | | | | | There were instances of strncmp() that were formatted improperly (e.g. whitespace around parameter before closing parenthesis) that caused the earlier mechanical conversion step to miss them. This step cleans them up. Signed-off-by: Junio C Hamano <junkio@cox.net>
* prefixcmp(): fix-up mechanical conversion.Junio C Hamano2007-02-20
| | | | | | | | | | | | | Previous step converted use of strncmp() with literal string mechanically even when the result is only used as a boolean: if (!strncmp("foo", arg, 3)) ==> if (!(-prefixcmp(arg, "foo"))) This step manually cleans them up to read: if (!prefixcmp(arg, "foo")) Signed-off-by: Junio C Hamano <junkio@cox.net>
* Mechanical conversion to use prefixcmp()Junio C Hamano2007-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>

I first saved them with "format-patch -4", and then did a reset at @{8}. At @{7}, I applied one of them with "am", and then used "git-apply" on the other one, and amended the commit at @{6} (so @{6} and @{7} has the same parent). I did not like the log message, so I amended again at @{5}. Then I cherry-picked @{9}~2 to create @{3} (the log message shows that it needs to learn to set GIT_REFLOG_ACTION -- it uses "git-commit" and the log entry is attributed for it). Another cherry-pick built @{2} out of @{9}, but what I wanted to do was to squash these two into one, so I did a "reset HEAD^" at @{1} and then made the final commit by amending what was at the top.

* simplify inclusion of system header files.Junio C Hamano2006-12-20
| | | | | | | | | | | | | | | | | | | | This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>

* show-branch: mark active branch with a '*' againJohannes Schindelin2006-09-21
| | | | | | | | | | | | | | This was lost in the packed-ref updates. The original test was a bit dubious, so I cleaned that up, too. It fixes the case when the current HEAD is refs/heads/bla/master: the original test was true for both bla/master _and_ master. However, it shares a hard-to-fix bug with the original test: if the current HEAD is refs/heads/master, and there is a branch refs/heads/heads/master, then both are marked active.

* Tell between packed, unpacked and symbolic refs.Junio C Hamano2006-09-20
| | | | | | | | | This adds a "int *flag" parameter to resolve_ref() and makes for_each_ref() family to call callback function with an extra "int flag" parameter. They are used to give two bits of information (REF_ISSYMREF and REF_ISPACKED) about the ref. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Add callback data to for_each_ref() family.Junio C Hamano2006-09-20
| | | | | | | | | | | | | | | | | | | | This is a long overdue fix to the API for for_each_ref() family of functions. It allows the callers to specify a callback data pointer, so that the caller does not have to use static variables to communicate with the callback funciton. The updated for_each_ref() family takes a function of type int (*fn)(const char *, const unsigned char *, void *) and a void pointer as parameters, and calls the function with the name of the ref and its SHA-1 with the caller-supplied void pointer as parameters. The commit updates two callers, builtin-name-rev.c and builtin-pack-refs.c as an example. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Make ref resolution sanerLinus Torvalds2006-09-17
| | | | | | | | | | | | | | | | The old code used to totally mix up the notion of a ref-name and the path that that ref was associated with. That was not only horribly ugly (a number of users got the path, and then wanted to try to turn it back into a ref-name again), but it fundamnetally doesn't work at all once we do any setup where a ref doesn't have a 1:1 relationship with a particular pathname. This fixes things up so that we use the ref-name throughout, and only turn it into a pathname once we actually look it up in the filesystem. That makes a lot of things much clearer and more straightforward. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
* Replace uses of strdup with xstrdup.Shawn Pearce2006-09-02
| | | | | | | | | | | | | | | | Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code.

* show-branch: Fix another performance problem.Alexandre Julliard2006-07-23
| | | | | | | | | | | When naming commits, stop walking the parent chain as soon as we find a commit that already has a name. The parent chain of that commit will be walked later on in any case (or may even have been walked already). This avoids O(n^2) behavior; on a tree where show-branch displays 6800 commits, the total run time drops from 77 seconds to 5 seconds.

* show-branch: fix performance problem.Junio C Hamano2006-07-16
| | | | | | | | | | | | | | | | | | | | The core function used in show-branch, join_revs(), was supposed to be exactly the same algorithm as merge_bases(), except that it was a version enhanced for use with more than two heads. However, it needed to mark and keep a list of all the commits it has seen, because it needed them for its semi-graphical output. The function to implement this list, mark_seen(), stupidly used insert_by_date(), when it did not need to keep the list sorted during its processing. This made "show-branch --merge-base" more than 20x slower compared to "merge-base --all" in some cases (e.g. between b5032a5 and 48ce8b0 in the Linux 2.6 kernel archive). The performance of "show-branch --independent" suffered from the same reason. This patch sorts the resulting list after the list traversal just once to fix these problems.

* Move "void *util" from "struct object" into "struct commit"Linus Torvalds2006-06-17
| | | | | | | | | | | | | | | | | Every single user actually wanted this only for commit objects, and we have no reason to waste space on it for other object types. So just move the structure member from the low-level "struct object" into the "struct commit". This leaves the commit object the same size, and removes one unnecessary pointer from all other object allocations. This shrinks memory usage (still at a fairly hefty half-gig, admittedly) of "git-rev-list --all --objects" on the mozilla repo by another 5% in my tests.

* Shrink "struct object" a bitLinus Torvalds2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shrinks "struct object" by a small amount, by getting rid of the "struct type *" pointer and replacing it with a 3-bit bitfield instead. In addition, we merge the bitfields and the "flags" field, which incidentally should also remove a useless 4-byte padding from the object when in 64-bit mode. Now, our "struct object" is still too damn large, but it's now less obviously bloated, and of the remaining fields, only the "util" (which is not used by most things) is clearly something that should be eventually discarded. This shrinks the "git-rev-list --all" memory use by about 2.5% on the kernel archive (and, perhaps more importantly, on the larger mozilla archive). That may not sound like much, but I suspect it's more on a 64-bit platform. There are other remaining inefficiencies (the parent lists, for example, probably have horrible malloc overhead), but this was pretty obvious. Most of the patch is just changing the comparison of the "type" pointer from one of the constant string pointers to the appropriate new TYPE_xxx small integer constant.
