Junio C Hamano	ef1d9c5aa4	log and diff family: honor config even from subdirectories There currently is an unfortunate circular dependency between what init_revisions (the command line revision specification parser) does and setting up the log and diff options. The function uses setup_git_directory() to find the root of the project relative to the current directory and calls diff_setup() to prepare diff generation. However, some of the things that diff_setup() does needs to depend on the configuration variable, which needs to be read after setup_git_directory() is called. This patch is a low impact workaround. It first lets init_revisions() to run and do its thing, then uses git_config() and diff_setup() after it returns, so that configuration variables that affects the diff operation can be used from subdirectories.

Junio C Hamano	9919f41c91	git-diff A...B to (usually) mean "git-diff `git-merge-base A B` B" This tweaks the argument parser of "git diff" to allow "git-diff A...B" to show diffs leading to B since their merge-base, when there is only one sensible merge base between A and B. Currently nonsense cases are thrown at combined-diff to produce nonsense results, which would eventually need to be fixed. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	1974632c66	Remove TYPE_* constant macros and use object_type enums consistently. This updates the type-enumeration constants introduced to reduce the memory footprint of "struct object" to match the type bits already used in the packfile format, by removing the former (i.e. TYPE_* constant macros) and using the latter (i.e. enum object_type) throughout the code for consistency. Eventually we can stop passing around the "type strings" entirely, and this will help - no confusion about two different integer enumeration.

Pavel Roskin	82e5a82fd7	Fix more typos, primarily in the code The only visible change is that git-blame doesn't understand "--compability" anymore, but it does accept "--compatibility" instead, which is already documented.

Junio C Hamano	83ad63cfeb	diff: do not use configuration magic at the core-level The Porcelainish has become so much usable as the UI that there is not much reason people should be using the core programs by hand anymore. At this point we are better off making the behaviour of the core programs predictable by keeping them unaffected by the configuration variables. Otherwise they will become very hard to use as reliable building blocks. For example, "git-commit -a" internally uses git-diff-files to figure out the set of paths that need to be updated in the index, and we should never allow diff.renames that happens to be in the configuration to interfere (or slow down the process). The UI level configuration such as showing renamed diff and coloring are still honored by the Porcelainish ("git log" family and "git diff"), but not by the core anymore.

Timo Hirvonen	c9b5ef998a	Set default diff output format after parsing command line Initialize output_format to 0 instead of DIFF_FORMAT_RAW so that we can see later if any command line options changed it.

Linus Torvalds	1f1e895fcc	Add "named object array" concept We've had this notion of a "object_list" for a long time, which eventually grew a "name" member because some users (notably git-rev-list) wanted to name each object as it is generated. That object_list is great for some things, but it isn't all that wonderful for others, and the "name" member is generally not used by everybody. This patch splits the users of the object_list array up into two: the traditional list users, who want the list-like format, and who don't actually use or want the name. And another class of users that really used the list as an extensible array, and generally wanted to name the objects. The patch is fairly straightforward, but it's also biggish. Most of it really just cleans things up: switching the revision parsing and listing over to the array makes things like the builtin-diff usage much simpler (we now see exactly how many members the array has, and we don't get the objects reversed from the order they were on the command line). One of the main reasons for doing this at all is that the malloc overhead of the simple object list was actually pretty high, and the array is just a lot denser. So this patch brings down memory usage by git-rev-list by just under 3% (on top of all the other memory use optimizations) on the mozilla archive. It does add more lines than it removes, and more importantly, it adds a whole new infrastructure for maintaining lists of objects, but on the other hand, the new dynamic array code is pretty obvious. The change to builtin-diff-tree.c shows a fairly good example of why an array interface is sometimes more natural, and just much simpler for everybody.

Linus Torvalds	885a86abe2	Shrink "struct object" a bit 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.

Junio C Hamano	0fe7c1de16	built-in diff: assorted updates. "git diff(n)" without --base, --ours, etc. defaults to --cc, which usually is the same as -p unless you are in the middle of a conflicted merge, just like the shell script version. "git diff(n) blobA blobB path" complains and dies. "git diff(n) tree0 tree1 tree2...treeN" does combined diff that shows a merge of tree1..treeN to result in tree0. Giving "-c" option to any command that defaults to "--cc" turns off dense-combined flag. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
