634217 - Change the crash signature max size from 255 characters to 244 characters

Status: RESOLVED DUPLICATE of bug 587142

(Socorro :: General, task)

Description

[Scoobidiver (away)]

Currently the crash signature max size in Socorro and the summary max size in Bugzilla are 255 characters.
We are unable to write correctly syntaxed summary in Bugzilla for long crash signatures.
In order to be able to write in the summary: crash [@ signature ], the crash signature size must be limited to 244 characters.

I don't see how we can do this without losing useful information. I think we really ought to get a larger field to use in Bugzilla. :-/

The useful information is in the stack trace.
Without doing that, we see in Socorro crash signatures with no associated bug even if there is one.
For instance:
nsTArray<mozilla::DOMSVGPathSegList::ItemProxy, nsTArrayDefaultAllocator>::Clear() | nsTArray<mozilla::widget::WindowHook::CallbackData, nsTArrayDefaultAllocator>::~nsTArray<mozilla::widget::WindowHook::CallbackData, nsTArrayDefaultAllocator>() | gfxDW...

I'd rather not truncate the Socorro information, that seems short sighted.

Would changing the bugzilla associator script solve the problem?

I don't think so. Indeed, if I have:
* bug X: crash [ @A ]
* 2 crash signatures: Aa, Ab
These 2 crash signatures will be associated to bug X even if they musn't.
If A has 244 characters, there won't be a problem.

If it is easier to extend the Bugzilla summary size to 266 characters, I take.

There are several bugs open already on facets of the signature-length problem, like bug 567012, bug 502820, and bug 587142 (of which this is a direct dupe).
