Is there a command line option that will find this artifact? I thought
perhaps the root:trunk symbolic name would find it, but I was wrong. It
finds c06edd231fc15d145a1c96c39b8fecdb79b33523 which is apparently where
the current trunk began from a branch.
Of course the following works, but I have to guess at the number of
artifacts:
fossil timeline -n 10 | tail
actually, you don't need to guess any more since `n 0' now yields so whole
timeline. so
fossil timeline -n 0 |tail -2 | awk -F[][] 'NR == 1 {print $2}'
should yield the SHA1 hash of initial checkin (for recent versions of
`fossil' emitting the trailing `+++ end of timeline (10587) +++' message).
but I just think (repeat it until it sticks ;-):
http://en.wikipedia.org/wiki/Carthago_delenda_est) this is another
instance where fossil would profit from supporting incremental revision
numbers in the respective local repo so that one could just update to
revision no. 0.

Re: [fossil-users] Parent of the very first checkin?
How is what you are looking for different from checking out the very first node in your tree, the "initial empty check-in"? I used to do what you are describing quite extensively when I used monotone. But with monotone it was easy to sync a subset of branches or revision trees from one repo to another. In fossil this is not possible. Once the multiple revision trees are in the same repo they cannot be separated using native tools. You could conceivably export and separate in some other tool I suppose. Anyhow, this factor made it impractical for me to keep different trees in the same repo. I'd be curious to hear a description of your methodology. On Fri, Dec 20, 2013 at 4:23 PM, David Given wrote: > hg has a concept of the changeset with uuid > .

If I understand what you're looking for (first empty commit?), when I asked this question some time ago, somebody suggested I just tag it myself. Simple solution, Just Works.

Every repository as an initial check-in which is empty. But it always has a different SHA1 hash, since it also includes the timestamp from when the repository was created.

[fossil-users] Parent of the very first checkin?
hg has a concept of the changeset with uuid . This is the empty changeset, and is equivalent to the parent of the very first checkin. Checking out this changeset will give you an empty repository; checking in with this as the parent will give you a new tree, not connected to the old one. I find myself needing to do this in Fossil: both as something I can check out to remove all files from the working directory, and something I can use as a parent so I can create multiple revision trees. AFAIK there's nothing in the Fossil architecture to forbid it --- is there any way I can do this? -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ─ http://www.cowlark.com ─ │ "There does not now, nor will there ever, exist a programming │ language in which it is the least bit hard to write bad programs." --- │ Flon's Axiom signature.asc Description: OpenPGP digital signature ___ fossil-users mailing list fossil-users@lists.fossil-scm.org http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users
