searchTasks with hardware_is_linked_to_bug parameter times out regularly

[Brian Murray]

When trying to search for bug tasks related to a particular bit of hardware it is always timing out for me. Consider the following search:

ubuntu = launchpad.distributions['ubuntu']
ubuntu.searchTasks(hardware_bus='PCI',hardware_vendor_id='0x8086',hardware_product_id='0x293a',hardware_is_linked_to_bug=False)

gave me OOPS-1522EC1058. Ubuntu has a lot of bug reports so I thought I'd try a package (simple-scan) with a small number of bug reports.

package = ubuntu.getSourcePackage(name='simple-scan')
tasks = package.searchTasks(hardware_bus='PCI',hardware_vendor_id='0x8086',hardware_product_id='0x293e',hardware_is_linked_to_bug=True)

This also returned OOPS-1522ED995.

I also tried some variations of this query link hardware_is_linked_to_bug=False and hardware_owner_is_bug_reporter=True and that also OOPSes.

Most of these happened using Edge but I tried switching to Production and that resulted in an OOPS also.

Oh, and I did link bug 521070 about simple-scan to a hardware profile that contains the searched for device.

[Brian Murray (brian-murray)]

Well it started working now but I still wonder what is causing this and if it is likely to happen again.

[Brian Murray (brian-murray)]

An oops from today - OOPS-1530EB842.

Actually in the description I said to use this:

ubuntu.searchTasks(hardware_bus='PCI',hardware_vendor_id='0x8086',hardware_product_id='0x293a',hardware_is_linked_to_bug=False)

However, if using False it doesn't oops but with hardware_is_linked_to_bug=True it does.

OOPS-1530EA891

The fix for this could be involved, and Brian has some work arounds he can explore. If it continues to be a problem and the suggested work arounds don't work as hoped, we can mark this a higher priority and see that the work is done.

@Brian, I hate to ask for noddy retests, but I'm wondering if this still occurs - and if so can you please attach a new OOPS? We've made lots of changes to searchTasks...

[Brian Murray (brian-murray)]

The same queries no longer cause an OOPS.

Ok, I'm going to close this optimistically. Thanks for retesting.
