[9fans] troubleshooting pull from sources

[9fans] troubleshooting pull from sources

[James Chapman]

Hi,

When I run 'pull' it just produces no output and just sits there
apparently for ever. I can run '9fs sources' and navigate around in
/n/sources/. Is there a lock file or something I should delete? Any
suggestions for debugging?

Thanks,

James

I was going to raise the alarm before, but too many other priorities
put Plan 9 on backburner.

That said, I abandoned a "pull -v" to its own devices and I see that
it actually overcame obstacles and proceeded past the blocking point.
I left it running when it reached:

	...

	d 386/ld.com 775 sys sys 1252805896

	c sys/src/9/omap/fpiarm.c
	c sys/src/9/bitsy/fpiarm.c

and sat, and sat, and sat.

But I see now that it got going again, no idea when or how long after
the above:

	c sys/src/9/bitsy/mmu.c
	c sys/src/9/kw/fpiarm.c
	! sys/lib/man/lookman/index: locally modified; will not overwrite

	a sys/src/cmd/unix/drawterm/posix-arm/md5block.c 664 sys sys 1341726493
	...

so maybe patience is the critical issue here?  Or an error somewhere?

I'm going to try again.  Yep, it seems to jam somewhere, if it unjams
I'll let the list know.

It seems so!

I left it for several hours yesterday afternoon and it eventually
sprung to life.

Thanks for the responses,

can you mount the same channel in another window and still use it,
or is the connection dead?  if the latter, it's likely an mtu problem.
see ip(3) on how to set.

if that's not it, i've also seen the replica commands deadlock.
backtraces would be helpful.
