GIT mirror of BZR repo

GIT mirror of BZR repo

[KESHAV P.R.]

Is it possible to update the GIT repo git://repo.or.cz/grub2.git to be
in sync with BZR repo. Since grub2 changed from svn to bzr it has not
been updated. BZR is very, very slow to update. It downloads about 3
MB for very few changes.

These are the changes that bzr did, for which it downloaded 3 MB of
data (for what?).

I connect to net using GPRS and I get only about 3-5 kbps speed. It
took 20 mins to just update from rev 2249 to 2250. What exactly is bzr
downloading for such a small patch? I used "bzr pull" . Git is much
faster, it wouldn't take 30 seconds for git to update download and
update the above patch if grub2 was git repo. I request you guys to
re-enable the above mentioned git repo, or tell me some way to make
bzr faster like git (for GPRS speeds). Thank you.

The git repository was only used before we switched to bzr.  To my
knowledge, it has not been used since.

This is a bug in the Savannah hosting service, not in bzr.  A fix for it
appears to be in progress:

  https://savannah.gnu.org/support/?107077

Until this is fixed, if you have difficulty with the download size of
updates, you can use the bzr mirror on Launchpad, which is updated
several times a day:

  https://code.launchpad.net/~vcs-imports/grub/grub2-bzr
  bzr get lp:grub/grub2

It would if git were artificially limited to an inferior transport
mechanism the way that bzr currently is on Savannah.  Right now, you are
not comparing like with like.  With sftp, bzr basically ends up forced
to redownload much of the branch metadata for every operation; it can do
much, much better with bzr+ssh.

Hi,

AFAIK, Roland Mas from FusionForge is currently working on bzr-git,
which would provide access to a bzr repo via git transports.

FWIW, I'm quite impressed with mksh interactively. I thought it was much
*much* more bare bones. But it turns out it beats the living hell out of
ksh93 in that respect. I'd even consider it for my daily use if I hadn't
wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh

Thanks for the commands. It works faster now. Please include
grub-extras also ( http://bzr.savannah.gnu.org/r/grub-extras/ ) in
launchpad.

Actually, forget that, since that requires authentication.  Run this
command instead of editing .bzr/branch/branch.conf by hand:

  bzr pull --remember lp:grub/grub2

If you have further queries about file transfer sizes, please ask a
mailing list or IRC channel specific to Bazaar; it is free software, and
like all software no doubt it can and should be improved.  This is not
the right place to ask about the fine details.

Yes, please provide an uptodate GIT mirrot of the grub
sources.

I've simply stopped trying to work on grub after the
transition to bzr, using it is just too painful.

Mandating bzr for the master repository is fine, but
not providing alternatives for people who just want
to keep up with the tree is not.

Re: GIT mirror of BZR repo

[KESHAV P.R.]

I changed .bzr/branch/branch.conf

parent_location = http://bzr.savannah.gnu.org/r/grub/trunk/grub/

to

parent_location = https://code.launchpad.net/~vcs-imports/grub/grub2-bzr

Response time is faster but the amount of data downloaded is way too
much for the size of the patch, downloaded 2100 KB for updating from
rev 2250 to 2251. I use bzr only for grub2 repo. If u guys have any
plans for a git repo (or mirror) , I will be glad to change over to
it.

What exactly is bzr downloading in this 2100 KB apart from this patch ?
