2006-06-19Don't use empty structure initializers.Florian Forster
Empty initializers for structures are not allowed in ANSI C99. This patch removes such an initializer from `builtin-read-tree.c'. Since the struct was static (and is therefore implicitely initialized to zero anyway) it wasn't actually needed.

2006-06-06Make index file locking code reusable to others.Junio C Hamano
The framework to create lockfiles that are removed at exit is first used to reliably write the index file, but it is applicable to other things, so stop calling it "cache_file". This also rewords a few remaining error message that called the index file "cache file". Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-06-05read-tree: fix eye-candy.Linus Torvalds
Anton Blanchard spotted that watching checkout stage of a clone on a slow terminal takes ages because it forgot to clear the "once a second happened" flag, so instead of updates the percentage output for every file it checks out after the first second has passed.

2006-06-04read-tree --reset: update working tree file for conflicted paths.Junio C Hamano
The earlier "git reset --hard" simplification stopped removing leftover working tree files from a failed automerge, when switching back to the HEAD version that does not have the paths. This patch, instead of removing the unmerged paths from the index, drops them down to stage#0 but marks them with mode=0 (the same "to be deleted" marker we internally use for paths deleted by the merge). one_way_merge() function and the functions it calls already know what to do with them -- if the tree we are reading has the path the working tree file is overwritten, and if it doesn't the working tree file is removed.

2006-05-31tree_entry(): new tree-walking helper functionLinus Torvalds
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.

2006-05-30Remove last vestiges of generic tree_entry_listLinus Torvalds
The old tree_entry_list is dead, long live the unified single tree parser. Yes, we now still have a compatibility function to create a bogus tree_entry_list in builtin-read-tree.c, but that is now entirely local to that very messy piece of code. I'd love to clean read-tree.c up too, but I'm too scared right now, so the best I can do is to just contain the damage, and try to make sure that no new users of the tree_entry_list sprout up by not having it as an exported interface any more.

2006-05-30Remove "tree->entries" tree-entry list from tree parserLinus Torvalds
Instead, just use the tree buffer directly, and use the tree-walk infrastructure to walk the buffers instead of the tree-entry list. The tree-entry list is inefficient, and generates tons of small allocations for no good reason. 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. Some programs still use the old tree-entry lists, and are a bit painful to convert without major surgery. For them we have a helper function that creates a temporary tree-entry list on demand.

2006-05-30Make "tree_entry" have a SHA1 instead of a union of object pointersLinus Torvalds

2006-05-30Make "struct tree" contain the pointer to the tree bufferLinus Torvalds
This allows us to avoid allocating information for names etc, because we can just use the information from the tree buffer directly. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
