A list of requirements for a possible replacement for CVS as repo software for NetBSD and pkgsrc so we don't keep starting over listing these (and forgetting half) all of the time:

Please add/correct.

Experiences in using the software

Experiences with Fossil

Aleksej Saushev (asau)

I started using it before conversion tool were available (basically it isn't available yet, to my knowledge Joerg is working on it), in addition I wanted to start as soon as possible and to try operation with no conversion tool available. Thus I've tried to simulate working with "vendor branches".

For now Fossil lacks some essential features and has other severe problems:

  1. Many operations require javascript-capable web browser.
  2. No support for vendor branches.
  3. Redundant to "There's no support for importing vendor source"?
  4. No, it is different. I would import manually, if only some support were there.
  5. It is impossible to merge between trees growing from the very root. The initial commit is too special, this prevents using these trees for vendor branches.
  6. Fixed in [4e3cd6ce4e].
  7. 2010-11-08, not in pkgsrc.
  8. There's no support for importing vendor source, even "addremove" command isn't in trunk at the time of writing.
  9. It has been merged to trunk and is part of the pkgsrc version.
  10. No, it isn't part of pkgsrc version at the moment, TIAS.
  11. Sorry, you are right. Merged to trunk in [ceab53718f].
  12. Merge state sticks. You can't undo it.
  13. Not sure what you mean, but "revert" resets the merge state since [d13054ce84].
  14. This is quite recent (late October) fix, I didn't check it.
  15. You can't amend your source when you've just merged, you are forced to commit after merge.
  16. To clarify, the merge has to be committed first, no separate commits are possible from the checkout before that.
  17. In practice this makes critical defect in combination of "fossil diff" inability to generate difference for added files.
  18. You can't tune diff command to ignore RCS keywords.
  19. Since RCS keywords are not really a native command, it is no surprise. An external diff program can be used for this purpose though.
  20. Since there's no external diff program that supports it, it is really not quite easy.
  21. You can't diff single file between two given versions.
  22. diff --from version1 --to version2 path/to/file
  23. That didn't work, and I'm not sure it works now. It used to ignore path-to-file argument. (It used to bail out when both "--from" and "--to" were used.)
  24. There's no way to change commit messages.
  25. easily done via ui: select a commit and under "Other Links" you can find "Edit" (given the necessary permissions).
  26. How? It should be possible via command line nevertheless.
  27. There's no documented way to select commit messages of current branch, or branch by given commit id. Or there's a bug preventing it.
  28. fossil info
  29. This isn't about "info" command, it is about "timeline" --> Please clarify what you mean.
  30. BTW, this command doesn't support "-R" flag, perhaps you have to check the source out to use it.
  31. Commands are under-documented, usage messages don't list many available options. This applies to trunk at least, there's a branch that states documentation as its goal.
  32. There's no convenient way to look at commit contents: files affected, diff.
  33. fossil ui and use a web browser
  34. We don't have web browser in base system, this information should be accessible with command line.

Some of above problems are reported.

Note, all problems above are usability problems, I didn't explore e.g. scalability, Joerg did and had problems, but this is another story.

We use bzr at work (MySQL), and while it has a number of problems, it does make dev work easy.

The Good

The Bad:

The Ugly:

A basic example workflow

# create a local shared repository. all objects are held in a .bzr sub-directory, with branches essentially a lightweight checkout
$ bzr init-repo bzr
$ cd bzr

# fetch HEAD, will take a long time, depending on connectivity
$ bzr branch bzr+ssh://

# fetch netbsd-5, as we already have the majority of the code in netbsd-trunk (and therefore .bzr), this takes a fraction of the time
$ bzr branch bzr+ssh://

# ok, let's do some dev work
$ bzr branch netbsd-trunk netbsd-trunk-sketch-fix-msk
$ cd netbsd-trunk-sketch-fix-msk; hack hack hack

# the usual cycle of hack/commit/merge
$ bzr diff # show uncommitted diffs
$ bzr commit # commit to local clone
$ bzr merge ../netbsd-trunk # update clone to latest local trunk, OR
$ bzr merge bzr+ssh:// # merge directly from upstream

# publish our tree for others to review/hack on
$ bzr push bzr+ssh://

# got reviewed/tested, let's push it
$ bzr merge bzr+ssh://
$ bzr missing bzr+ssh:// # show changeset differences
$ bzr push bzr+ssh://

I personally find this approach a lot more natural than git's way of managing branches itself inside a single working directory.



We have a successful conversion from cvs to fossil since ~mid 2011, mostly thanks to the work of Jörg Sonnenberger. See github for more details.


We have a successful conversion to git via the fossil conversion; also, probably now a successful direct conversion via the tools by Eric S. Raymond. See github for more details.


A conversion to hg has also been done, ask agc@
