* Initialize tree descriptors with a helper function rather than by hand.Linus Torvalds2007-03-21
| | | | | | | | | | | | | This removes slightly more lines than it adds, but the real reason for doing this is that future optimizations will require more setup of the tree descriptor, and so we want to do it in one place. Also renamed the "desc.buf" field to "desc.buffer" just to trigger compiler errors for old-style manual initializations, making sure I didn't miss anything.

* | convert object type handling from a string to a numberNicolas Pitre2007-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently have two parallel notation for dealing with object types in the code: a string and a numerical value. One of them is obviously redundent, and the most used one requires more stack space and a bunch of strcmp() all over the place. This is an initial step for the removal of the version using a char array found in object reading code paths. The patch is unfortunately large but there is no sane way to split it in smaller parts without breaking the system.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Don't force everybody to call setup_ident().Junio C Hamano2007-01-28
| | | | | | | | | | | | Back when only handful commands that created commit and tag were the only users of committer identity information, it made sense to explicitly call setup_ident() to pre-fill the default value from the gecos information. But it is much simpler for programs to make the call automatic when get_ident() is called these days, since many more programs want to use the information when updating the reflog.

* Don't die in git-http-fetch when fetching packs.Shawn O. Pearce2007-01-09
| | | | | | | | | | | | | | | | My sp/mmap changes to pack-check.c modified the function such that it expects packed_git.pack_size to be populated with the total bytecount of the packfile by the caller. But that isn't the case for packs obtained by git-http-fetch as pack_size was not initialized before being accessed. This caused verify_pack to think it had 2^32-21 bytes available when the downloaded pack perhaps was only 305 bytes in length. The use_pack function then later dies with "offset beyond end of packfile" when computing the overall file checksum. Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | Any git command that expects to work in a subdirectory of a project, and that reads the git config files (which is just about all of them) needs to make sure that it does the "setup_git_directory()" call before it tries to read the config file. This means, among other things, that we need to move the call out of "init_revisions()", and into the caller. This does the mostly trivial conversion to do that.

The speed difference is even more noticeable when committing large files, which is now up to 8 times faster.

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.

* 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.

* tree_entry(): new tree-walking helper functionLinus Torvalds2006-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a "tree_entry()" function that combines the common operation of doing a "tree_entry_extract()" + "update_tree_entry()". It also has a simplified calling convention, designed for simple loops that traverse over a whole tree: the arguments are pointers to the tree descriptor and a name_entry structure to fill in, and it returns a boolean "true" if there was an entry left to be gotten in the tree. This allows tree traversal with struct tree_desc desc; struct name_entry entry; desc.buf = tree->buffer; desc.size = tree->size; while (tree_entry(&desc, &entry) { ... use "entry.{path, sha1, mode, pathlen}" ... } which is not only shorter than writing it out in full, it's hopefully less error prone too. [ It's actually a tad faster too - we don't need to recalculate the entry pathlength in both extract and update, but need to do it only once. Also, some callers can avoid doing a "strlen()" on the result, since it's returned as part of the name_entry structure. However, by now we're talking just 1% speedup on "git-rev-list --objects --all", and we're definitely at the point where tree walking is no longer the issue any more. ] NOTE! Not everybody wants to use this new helper function, since some of the tree walkers very much on purpose do the descriptor update separately from the entry extraction. So the "extract + update" sequence still remains as the core sequence, this is just a simplified interface. We should probably add a silly two-line inline helper function for initializing the descriptor from the "struct tree" too, just to cut down on the noise from that common "desc" initializer.

The tree-walk infrastructure is generally no harder to use than following a linked list, and allows us to do most tree parsing in-place.

* Make "--parents" logs also be incrementalLinus Torvalds2006-04-08
| | | | | | | | | | | | | | | | | | | The parent rewriting feature caused us to create the whole history in one go, and then simplify it later, because of how rewrite_parents() had been written. However, with a little tweaking, it's perfectly possible to do even that one incrementally. Right now, this doesn't really much matter, because every user of "--parents" will probably generally _also_ use "--topo-order", which will cause the old non-incremental behaviour anyway. However, I'm hopeful that we could make even the topological sort incremental, or at least _partially_ so (for example, make it incremental up to the first merge). In the meantime, this at least moves things in the right direction, and removes a strange special case.
