Using r4842 of bzr.dev, running bzr selftest, I get a lot of errors along the following lines:

I can reproduce this in a clean checkout with no C extensions built.

John, I think I just found the bug, see my patch in <lp:~spiv/bzr/static-tuple-pure-python-bug-490600>

[Russel Winder (russel)]

OK guys, this has moved from "extremely serious" to "beyond a $$$$$$$ joke". I can't even get Bazaar with Bazaar now.

There followsa number of crash files from this evening attempt to update various Bazaar branches. Sadly Launchpad requires that I submit them individually, which $$$$$.

Option 1: Compile your extensions. (make)

Option 2: update to the latest bzr.dev. It has 1 fix, I've already
proposed a second fix which seems to handle the rest of the cases.

Option 3: Use lp:~jameinel/bzr/2.1.0b4-490600-no-extensions until it
lands in bzr.dev. (Probably by tomorrow.)

Note that this has only been broken in bzr.dev since rev 4842, which
landed on Nov-30th, and we have one fix in rev 4846 on 12-01, and
another by 12-02. So it isn't like there has been a huge window of time
where not compiling the extensions was causing failures.

John,

Thanks for the prompt reply, much appreciated.

Can't do that cleanly as far as I know (and Martin tells me) as I have
my bzr.dev shared by Ubuntu 32-bit and 64-bit, Mac OS X and Solaris.
NFS mounts -- but you probably knew this given my loud irritation at
Linux and mmap and TDB and bzr-svn/bzr-git (not anything that
bzr-svn/bzr-git can do about it though :-(

This is what set me off, I am trying to update Bazaar bzr.dev and it is
not able to update because of the problem.

Interestingly I only get the StaticTuple problem when I update (I use
bound branches) If I try and pull I get:

        |> bzr pull
        Using saved parent location: http://bazaar-vcs.org/bzr/bzr.dev/
        bzr: ERROR: Cannot lock LockDir(lp-46125584:///~bzr-pqm/bzr/bzr.dev/.bzr/branchlock): Transport operation not possible: readonly transport

Hummm... I think something drastic may be needed, even
using /usr/bin/bzr to update or pull gives the same problems so I have
no version of Bazaar that is going to allow me to update my Bazaar
mirror. Looks like I'll have to ditch it and create a new shared
repository, mirror and working branch when the problem is fixed.

Though I may just not be thinking straight!

I had been trying to keep my bzr.dev updated at least once per day, so
far it has never been a problem, just now it seems this is a bad
policy :-( Anyway I am confident everything will become OK, so no
long-term problem, just a short-term panic as I need to use Bazaar in my
Python training course tomorrow!

If you run 'setup.py install --home ~' then I think it will install
the extensions into per-architecture directories under ~/lib, so they
will stay up to date. You will need to re-run this after each update
of bzr.dev. If it doesn't work, please either ask or file a bug as
appropriate.

Can you revert to a working revision? "bzr revert -r 4841", according to
what jam said.

That's right. Since you're using a bound branch, you're trying to pull
*to* http://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev/ (from
http://bazaar-vcs.org/bzr/bzr.dev/, its parent branch), which is
obviously not possible, since HTTP is read-only.

Martin,

Thanks for chipping in on this, I really appreciate it.

OK, that would solve the "technical" issue of having the checkout of
bzr.dev shared by many different architectures and yet still compiled.
However, the problem that remains is a "management" one, in that every
time I updated I would then have to login to each machine and run the
compilation (though I guess I could script such a compilation for all
the permanently connected machines). The huge advantage of not
compiling is that it works on all architectures just by updating on the
server and (I think this is the real "killer" point) I can Unison
synchronize the server copy to the laptops and back again in the full
knowledge that Bazaar will Just Work (tm) on all my machines.

NB I appreciate I get a performance hit by not compiling but the ease of
management across 7 machines outweighs this.

PS Matt's suggestion coming up prompted me to "do the right thing" and
I am now up to date with revision 4850.

Thanks.

As far as I can tell, I am not having any of the earlier problems with any of the repositories that were problematic, so I think this released fix is successful.

Thanks.
