Linus Torvalds 01796b0e91 Make "revision.h" slightly better to use.
- mark_reachable() can be more generic, marking the reachable revisions
   with an arbitrary mask.
 - date parsing will parse to a date of 0 rather than ULONG_MAX for the
   bad old case, sorting the dates correctly.

Linus Torvalds 89d21f4b64 Move "parse_commit()" into common revision.h file.
This also drops the old-style date parsing. We just don't care
enough, since we dropped that format pretty early.

Yes, this could do with some cleanup, and a common library file.
Some day.

Junio C Hamano c747fc6fac [PATCH] Remove unused arguments from index_fd()
The function index_fd() in update-cache.c takes 5 arguments, but
two is not necessary and one that is a pointer to a structure
really needs to be a pointer to one member of that structure.
This patch cleans it up.

Also it removes printf() apparently left after initial

Junio C Hamano 9fec8b26ef [PATCH] Do not run useless show-diff on unmerged paths repeatedly.
When run on unmerged dircache, show-diff compares the working
file with each non-empty stage for that path.  Two out of three
times, this is not very helpful.  This patch makes it report the
unmergedness only once per each path and avoids running the
actual diff.

Upper layer SCMs like Cogito are expected to find out mode/SHA1
for each stage by using "show-files --stage" and run the diff
itself.  This would result in more sensible diffs.

Junio C Hamano 9bd94cafdf [PATCH] show-diff shell safety
The command line for running "diff" command is built without
taking shell metacharacters into account.  A malicious dircache
entry "foo 2>bar" (yes, a filename with space) would result in
creating a file called "bar" with the error message "diff: foo:
No such file or directory" in it.

This is not just a user screwing over himself.  Such a dircache
can be created as a result of a merge with tree from others.

Here is a fix.

Linus Torvalds d99082e0e3 Make "read-tree" merge the trees it reads by giving them consecutive states.
Normally you'd use state 0 for the "merged" state, and start out with
state 1 being "origin", state 2 being "first tree" and state 3 being
"second tree".

Once all the index entries are back in state 0, we have a successful
merge and can write the result tree back.

Junio C Hamano aa1c48df81 [PATCH] ls-tree enhancements
This adds '-r' (recursive) option and '-z' (NUL terminated)
option to ls-tree.  I need it so that the merge-trees (formerly
known as git-merge.perl) script does not need to create any
temporary dircache while merging.  It used to use show-files on
a temporary dircache to get the list of files in the ancestor
tree, and also used the dircache to store the result of its
automerge.  I probably still need it for the latter reason, but
with this patch not for the former reason anymore.
