[Openstack] Glance unit test failing on SID, bad state for Nova in SID

2011-09-25 Thread Thomas Goirand
Hi, During the build process, I could see: test_add_image_with_image_data_as_file ERROR Any idea why it's doing this? Apart form that single unit test which is failing, Swift and Glance seems to build with no issue in SID. I didn't actually ran and test them *yet* on my test

It looks like you need to update python-novaclient to a newer version. Nova depends on python-novaclient for some tests, but it is shipped separately. Vish On Sep 25, 2011, at 3:48 AM, Thomas Goirand wrote: > Hi, > > During the build process, I could see: > test_add_image_with_image_data_as_fi

[Openstack] Nova DB Connection Pooling

2011-09-25 Thread Vishvananda Ishaya
Hey everyone, I'm a bit concerned with the connection pooling in the db. It seems that things are not getting cleaned up properly. I have a repro-case that causes failures that we have seen before. if I revert the nova/db/sqlalchemy/session.py to before the eventlet db pool was added I get n

What was the intent of the connection pooling? That is, what was it trying to fix? Running the script a single time caused 16 connection threads to be spawned. This seems a bit excessive. When I tried spawning five copies at the same time, I wound up with 60 connected threads, plus some connect t

Whoops! Ok- turns out I was running against system installed libs instead of trunk. doh. I can now not reproduce your issues with trunk. I spawned off 10 concurrent copies of that program. Now, some of them weren't able to get ips any more (since it's only configured for a pool of five of them.)

Hrm. It's not piling on with the locking like I originally thought - from the db's perspective there's not a whole hell of a lot going on, actually - even two copies of this script run concurrently cause them to totally get in to some app-level spinning that ends up with at least one script errorin

Because I'm just going to spam the list all afternoon... Out of curiousity, I ramped up the numbers in the script to get a most sustained attack on the db. With the old db code (pre pool) - running 10 concurrent copies of dbrepro.py gave me 10 db connections (as you'd expect) and a consistent sust

Hey Monty/All, The original goal of my eventlet connection pooling patch was to increase overall throughput of the OpenStack API. By itself, SQLAlchemy provides a lot of nifty features such as connection pooling and connection timeout limits, but all of these were being lost on us because of ou

Great stuff Stefano. These are going to be very valuable metrics. To start with, I'd draw your "commits per month" graph with a 1 year x-axis. This is a reasonable baseline for historical stats, and has the particular advantage in this case that it trims off the start-up phase of the project,
