2007-05-11read-tree -m -u: avoid getting confused by intermediate symlinks.Libravatar Junio C Hamano1-4/+10
When switching from a branch with both x86_64/boot/Makefile and i386/boot/Makefile to another branch that has x86_64/boot as a symlink pointing at ../i386/boot, the code incorrectly removed i386/boot/Makefile. This was because we first removed everything under x86_64/boot to make room to create a symbolic link x86_64/boot, then removed x86_64/boot/Makefile which no longer exists but now is pointing at i386/boot/Makefile, thanks to the symlink we just created. This fixes it by using the has_symlink_leading_path() function introduced previously for git-apply in the checkout codepath. Earlier, "git checkout" was broken in t4122 test due to this bug, and the test had an extra "git reset --hard" as a workaround, which is removed because it is not needed anymore.

2007-04-22delay progress display when checking out filesLibravatar Nicolas Pitre1-7/+2
Let's start displaying progress only if more than 50% of total number of files remains to be checked out after 2 seconds. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

If the progress bar ends up in a box, better provide a title for it too. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-22common progress display supportLibravatar Nicolas Pitre1-45/+9
Instead of having this code duplicated in multiple places, let's have a common interface for progress display. If someday someone wishes to display a cheezy progress bar instead then only one file will have to be changed. Note: I left merge-recursive.c out since it has a strange notion of progress as it apparently increase the expected total number as it goes. Someone with more intimate knowledge of what that is supposed to mean might look at converting it to the common progress interface.

2007-04-10Treat D/F conflict entry more carefully in unpack-trees.c::threeway_merge()Libravatar Junio C Hamano1-14/+20
This fixes three buglets in threeway_merge() regarding D/F conflict entries. * After finishing with path D and handling path D/F, some stages have D/F conflict entry which are obviously non-NULL. For the purpose of determining if the path D/F is missing in the ancestor, they should not be taken into account. * D/F conflict entry is a marker to say "this stage does _not_ have the path", so do not send them to keep_entry().

2007-04-10t1000: fix case table.Libravatar Junio C Hamano1-1/+1
Case #10 is not handled with unpack-trees.c:threeway_merge() internally, unless under the agressive rule, and it is not a bug. As the test expects, ND (one side did not do anything, other side deleted) case was meant to be handled by the caller's policy (e.g. git-merge-one-file or git-merge-recursive).

2007-04-04Fix switching to a branch with D/F when current branch has file D.Libravatar Junio C Hamano1-1/+112
This loosens the over-eager verify_absent() check that gets upset to find directory D in the current working tree when switching to a branch that has a file there. The check needs to make sure that we do not lose precious working tree files as a result of removing directory D and replacing it with the file from the other branch, which is a tad expensive but this is a less common case.

2007-04-04Fix twoway_merge that passed d/f conflict marker to merged_entry().Libravatar Junio C Hamano1-2/+8
When switching from one tree to another, we should not send a marker that says "this file does not exist in the new tree -- I am a placeholder to tell you that, and not a real blob" down to merged_entry() as the result of the merge.
2007-04-04unpack-trees: get rid of *indpos parameter.Libravatar Junio C Hamano1-9/+7
This variable keeps track of which entry in the original index the traversal is looking at, and belongs to the unpack_trees_options structure along with other traversal status information. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-04unpack_trees.c: pass unpack_trees_options structure to keep_entry() as well.Libravatar Junio C Hamano1-7/+7
Other decision functions, deleted_entry() and merged_entry() take one as their parameter, and this function should. I'll be introducing a separate index to build the result in, and am planning to pass it as the part of the structure. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-21Initialize tree descriptors with a helper function rather than by hand.Libravatar Linus Torvalds1-2/+1
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.

2006-12-20simplify inclusion of system header files.Libravatar Junio C Hamano1-2/+0
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>

2006-12-05read-tree: further loosen "working file will be lost" check.Libravatar Junio C Hamano1-5/+19
This follows up commit ed93b449 where we removed overcautious "working file will be lost" check. A new option "--exclude-per-directory=.gitignore" can be used to tell the "git-read-tree" command that the user does not mind losing contents in untracked files in the working tree, if they need to be overwritten by a merge (either a two-way "switch branches" merge, or a three-way merge).

2006-12-04unpack-trees: make sure "df_conflict_entry.name" is NUL terminated.Libravatar Junio C Hamano1-3/+5
The structure that ends with a flexible array member (or 0 length array with older GCC) "char name[FLEX_ARRAY]" is allocated on the stack and we use it after clearing its entire size with memset. That does not guarantee that "name" is properly NUL terminated as we intended on platforms with more forgiving structure alignment requirements. Reported breakage on m68k by Roman Zippel.

2006-10-27merge: loosen overcautious "working file will be lost" check.Libravatar Junio C Hamano1-3/+1
The three-way merge complained unconditionally when a path that does not exist in the index is involved in a merge when it existed in the working tree. If we are merging an old version that had that path tracked, but the path is not tracked anymore, and if we are merging that old version in, the result will be that the path is not tracked. In that case we should not complain. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-08-23Convert memcpy(a,b,20) to hashcpy(a,b).Libravatar Shawn Pearce1-1/+1
This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

Introduces global inline: hashcmp(const unsigned char *sha1, const unsigned char *sha2) Uses memcmp for comparison and returns the result based on the length of the hash name (a future runtime decision).
