And various cleanups that makes it able to not care.

Linus Torvalds e99d59ff0b sparse cleanup
Fix various things that sparse complains about:
 - use NULL instead of 0
 - make sure we declare everything properly, or mark it static
 - use proper function declarations ("fn(void)" instead of "fn()")

Sparse is always right.

Petr Baudis 06cd3b94b2 rev-tree now handles commit problems better
This fixes possible crashes in case of broken commit tree, and makes
rev-tree die in case it cannot parse a given commit.

Linus Torvalds 3c249c9506 Add "get_sha1()" helper function.
This allows the programs to use various simplified versions of
the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by
the .git/HEAD file etc.

For example, this commit has been done with

	git-commit-tree $(git-write-tree) -p HEAD

instead of the traditional "$(cat .git/HEAD)" syntax.

Linus Torvalds 5e7921e7c1 rev-tree.c: don't include unnecessary header files
We used to have all these time-related issues, long gone now.

Linus Torvalds 94dfb7f2e3 Fix NSEC compile problem, and properly parse the rev-tree cmd line.
The rev-tree thing just happened to work. It shouldn't have.

Linus Torvalds 3b7d368f34 Don't parse commit objects more than once.
Yes, the "parse_commit()" already checks for this condition, but
we need to check for it in rev-tree too, so that we don't start
walking the parent chain unnecessarily.

Daniel Barkalow 5873b67eef [PATCH] Port rev-tree to parsing functions
This ports rev-tree to use the parsing functions introduced in the
previous patches.

Linus Torvalds 15000d7899 Make "rev-tree.c" use the new-and-improved "mark_reachable()"
It used to have its own specialized version for marking the
sub-reachability bits.

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.

David Woodhouse 27de946d0e [PATCH] Simplify date handling and make it more reliable
This make all dates be stores as seconds since UTC epoch, with the
author's or committer's timezone as auxiliary data so that dates can be
pretty-printed in the original timezone later if anyone cares.  I left
the date parsing in rev-tree.c for backward compatibility but it can be
dropped when we change to base64 :)

commit-tree now eats RFC2822 dates as AUTHOR_DATE because that's
what you're going to want to feed it.

Yes, glibc sucks and strptime is a pile of crap. We have to parse it
ourselves.

Linus Torvalds 458754a9fe Use common "revision.h" header for both fsck and rev-tree.
It's really a very generic thing: the notion of one sha1 revision
referring to another one. "fsck" uses it for all nodes, and "rev-tree"
only tracks commit-node relationships, but the code was already
the same - now we just make that explicit by moving it to a common
header file.

Petr Baudis 2de381f919 [PATCH] Consolidate the error handling
Now there is error() for "library" errors and die() for fatal "application"
errors. usage() is now used strictly only for usage errors.

Linus Torvalds 40e88b95cd Make "rev-tree" able to read its own output again from the cache.
Also, add "date" information to the output so that you can do something
like this:

	rev-tree `cat .git/HEAD` | sort -nr | cut -d' ' -f2 | while read i; do cat-file commit $i; done

which basically becomes a "git log" (aka "git changes") where things are
sorted by time.

David Woodhouse 727ff27787 [PATCH] rev-tree support for "in X but not in Y".
To do the automated commit-mailing I need to be able to answer the
question "which commits are here today but weren't yesterday"...  i.e. 
given two commit-ids $HEAD and $YESTERDAY I want to be able to do:

	rev-tree $HEAD ^$YESTERDAY

to list those commits which are in the tree now but weren't
ancestors of yesterday's head.

Yes, I could probably do this with 
	rev-tree $HEAD $YESTERDAY | egrep -v ^[a-z0-9]*:3
but I prefer not to.

Linus Torvalds 771364af0e Make the rev-tree output more regular. This is the last
change. Promise.

It now always outputs all the revisions as <sha1>:<reachability>, where the
reachability is the bitmask of how that revision was reachable from the
commits in the argument list.

Trivially, if there is only one commit, the reachability will always be
(1 << 0) == 1 for all reachable revisions, and there won't be any edges
(so the "--edges" flag only makes sense with multiple commit keys).
2005-04-11 17:40:58 -07:00
Linus Torvalds 28258afe91 Make "rev-tree" capable of showing the difference in reachability between two
or more commit points.

This is important both to know what the difference between two commit
points is, but also to figure out where to try to merge from.

Linus Torvalds 97d9c3cdea Make "rev-tree" more efficient and more useful.
Slight change of output format: it now lists all parents on the same line.

This allows it to work on initial commits too (which have no parents), and
also makes the output format a lot more intuitive.
2005-04-11 16:42:13 -07:00
Linus Torvalds 84fe972055 Add a "rev-tree" helper, which calculates the revision
tree graph.

It's quite fast when the commit-objects are cached, but since
it has to walk every single commit-object, it also allows you
to cache an old state and just add on top of that.
