bzr: ERROR: curl connection error (Connection timed out)

[Bob Tanner]

cygwin
cygwin python 2.4.3
bzr 0.9.0dev0 revision 1890

Getting connection time outs under bzr and cygwin. And only this combination.
Using ActiveState's python I do not get these time outs (same repo).
Using linux I do not get these time outs.

Seems specific to cygwin.

bzr: ERROR: curl connection error (Connection timed out) on http://bazaar-ng.org/bzr/bzr.dev/.bzr/repository/knits/[randomly different]/XXXX.kndx

It would seem to be more of a bug in the specific version of pycurl that you have installed, rather than a bug in bzr.

Can you try the same action with:

bzr command http+urllib://url

And see if urllib under cygwin is having the same problem?

Also, I believe bazaar-vcs.org was down for a couple of hours last night due to hardware failure. So make sure the problem still exists.

This just seems like you are getting a real connection error. It doesn't seem to be a problem with pycurl or bzr. Just that your connection to bazaar-ng.org is timing out.

By the way, the real site is now 'bazaar-vcs.org', and bazaar-ng.org is just a redirect to bazaar-vcs.org. (If you use the bazaar-ng url, every request is going to be a redirect, and will be a lot slower bug 36004 is about fixing that, though).

The request it is timing out on isn't even all that big (only 800 or so bytes).

You might try using 'http://bazaar-vcs.org' and see if you have fewer timeouts.

Hmm, reboot this laptop into Linux and the bzr pull never times out. Same url,
but I'll try switching to the new url and see what happens.

Can this bug be reproduced while using the http://bazaar.launchpad.net/~bzr/bzr/bzr.urllib.keepalive branch ?

[Bob Tanner (tanner)]

Using http://bazaar.launchpad.net/~bzr/bzr/bzr.urllib.keepalive cygwin+bzr works fine.

[Bob Tanner (tanner)]

I'd like to add it seems much faster as well.

[Vincent Ladeuil (vila)]

That should be even better handled with the new redirection implementation.
