This is my bad. I added #include <ctype.h> to the file,
which I ended up not using and failed to remove it.

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.

This fixes some stylistic problems introduced by my previous set
of patches. I'll be sending my last patch to show-diff next,
which depends on this cleanup.

The show-diff command uses a variable "new" but it is always
used to point at the original data recorded in the dircache
before the user started editing in the working file. Rename it
to "old" to avoid confusion.

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.

This patch adds the -z option to the show-diff command,
primarily for use by scripts. The information emitted is
similar to that of -q option, but in a more machine readable
form. Records are terminated with NUL instead of LF, so that
the scripts can deal with pathnames with embedded newlines.

SCMs have ways to say "I want diff only this particular file",
or "I want diff files under this directory". This patch teaches
show-diff to do something similar. Without command line
arguments, it still examines everything in the dircache as
before.

The cache-entry names are all proper strings, no need to worry about
their length.

This adds the '-q' option for show-diff.c to squelch complaints for
missing files.
It is handy if you want to run it in the merge temporary directory after
running merge-trees with its minimum checkout mode, which is the
default, because you would not find any files other than the ones that
needs human validation after the merge there.
It also fixes the argument parsing bug Paul Mackerras noticed in
<16991.42305.118284.139777@cargo.ozlabs.ibm.com> but slightly
differently.

This allows using a git tree over NFS with different byte order, and
makes it possible to just copy a fully populated repository and have
the end result immediately usable (needing just a refresh to update
the stat information).

My convention is that contrary to files trimmed to zero size,
deleted files always go to /dev/null. This patch turns show-diff
to abide this.

This patch adds a -s flag for show-diff, which will surpress the
actual diffing. This is useful for my scripts when they just want
to see what needs to be updated in the cache.

The ideas is that using the show-diff to generate the
patch including deleted and new file (in the next patch).
So we don't have to do the temp new file diff dance on the
script.
The cache index now contain enough information to generate
the whole patch. So the GIT SCM don't need separate command
for check out file to edit or delete. Just do the edit and
remove and GIT will generate the correct patch.
It still require tell GIT to add new files.

It used to be useful before I wrote "show-files", so that
show-diff would also tell what the cached files were. Now
it's just annoying.
|
|
Like the cache filename finder, it's a generically useful function,
rather than something specific to the current "show-diff" thing.
|
|
And fix up the warnings that it pointed out. Let's keep the tree
clean from early on.
Not that the code is very beautiful anyway ;)

The tool interface sucks (especially "committing" information, which is just
me doing everything by hand from the command line), but I think this is in
theory actually a viable way of describing the world. So copyright it.
