I needed to add one more flag. --file <filename> to update, so that I
could get the update status quickly for a single file. The changes to
the function as below. I had to make the corresponding changes to
vc-fossil.el as well. I'm done for now, I have the "minimal"
frequently used functions working satisfactorily for vc mode to be
usable with fossil.

Subject: Re: [fossil-users] Finding out whether a file needs an update in C
This was probably a stupid question. What I really wanted to know was
- will the file change if I do a "fossil update". I now have a
newer version of emacs integration done.
Much thanks to drh for the finfo changes in the tree. My zip from
last time doesn't seem to have made it. I'm attaching files inline.
Here are the fossil related changes:
1. fossil finfo -b|--brief <filename> gives a brief
(one line per revision, and it prints revision numbers). The revision
numbers are checkin-numbers.
2. fossil finfo -s|--status <filename> prints the
edited state and the (checkin) revision numbers.
3. fossil finfo -p|--print -r|--revision <rev> <filename>. Prints the
file from the specified (checkin) revision number.
4. fossil update --local, does a local update without an autosync, even if
autosync was turned on.
5. fossil update -n|--nochange, goes through the update process (syncing if
--local
was not specified), but does not change any checked out file. It prints
out the actions it would do if -n was not specified
6. fossil update -v|--verbose, prints messages to stdout for unchanged/edited
files
The vc-fossil.el included here uses
fossil finfo -l -b
fossil finfo -s
fossil finfo -p -r
fossil update --local -n -v
fossil diff -r
first below is fossil diff of my clone, after 3.6.20 sqlite3 upgrade.
I have merged in drh's changes from this weekend. second is the
current vc-fossil.el. There must be a better way to submit patches,
but I don't know about it yet.
If it makes sense, I'd suggest adding vc-fossil.el as a new file to
the repository.
Thanks
- Venkat
