Listing branches in bzr

Listing branches in bzr

[Nick Roberts]

We've now got bzr which allows easier branching but all I've done is commit to
trunk. BzrForEmacsDevs appears to describe creating local branches but how
about branches on bzr.savannah.gnu.org?  Are there any?  

With git I think you can find out with "git branch -r".  I've tried bzr
branches "http://bzr.savannah.gnu.org/r/emacs" and "bzr branches
sftp://nickrob@bzr.savannah.gnu.org/srv/bzr/emacs/" but it just seems to hang.

No, it's just very slow. 5 minutes or more.

I checked out Emacs from Launchpad instead. I tried the branch command:

  bzr branches lp:emacs
  bzr: ERROR: http://bazaar.launchpad.net/~vcs-imports/emacs/trunk/
    is permanently redirected to /~vcs-imports/emacs/trunk/changes

What is the error message trying to tell me?

First, it is unlikely (although not impossible) that

http://bazaar.launchpad.net/~vcs-imports/emacs/trunk/

contains several branches. It *is* a branch.

bzr branches http://bazaar.launchpad.net/~vcs-imports/emacs/

returns an empty list. Given the special setup that Launchpad uses, it
is possible that the `branches' command does not work on it.

That said, the error report is quite cryptic, although it seems like
coming from the some deep API and may be difficult to interpret on the
outer layer were the plugin operates. If you are curious, file a bug
report on the Bazaar `bzrtools' plugin home:

I've just tried it for twenty minutes, or more, then given up.

time bzr branches http://bzr.savannah.gnu.org/r/emacs

returned the list of branches after 4m50s  (6Mbp/s ADSL, bzr 2.0.1)

OK, Now I see:

bzr branches http://bzr.savannah.gnu.org/r/emacs

real	6m42.968s
user	0m1.868s
sys	0m0.104s

and:

bzr branches sftp://nickrob@bzr.savannah.gnu.org/srv/bzr/emacs/

real	15m6.515s
user	0m2.236s
sys	0m0.100s

with the output below.  But using a web browser as Glenn describes, is
immediate.

Here it is

    real    00h10m08.281s
    user    00h00m08.031s
    sys     00h00m01.078s

(Windows XP SP2, 3.5Mbps cable, bzr 2.0.3)

I think the large discrepancy between `real' and `user'+`sys' means
that most of the time is spent waiting for the network.

As a comparison, doing bzr branches against a local rsymc mirror of the
repo on an old laptop with a slow drive and a cold cache took:

 3.23user 0.37system 0:16.70elapsed 21%CPU (0avgtext+0avgdata 56944maxresident)k
 22440inputs+8outputs (48major+4199minor)pagefaults 0swaps

So bzr branch is a /lot/ slower than it needs to be over http or sftp.

Yet another reason to demand bzr+ssh, yes?

You can just visit http://bzr.savannah.gnu.org/r/emacs/ with a web
browser to see what branches there are.

That does exactly what I want and it's immediate.

Thanks.

You can also visit sftp://bzr.sv.gnu.org/srv/bzr/emacs (via some SFTP
client), of course,

Not yet, but Real Soon Now.  (Stefan and I have more or less hashed our
plans out, but I'll let him explain the details...)

You are probably talking about post-23 branches.  Because older
branches inherited from CVS are already there, and there are quite a
few of them.

That's good to hear, thanks.
