The Reporter in @qa told me as steps to reproduce:
09:16 < satdav> I was on bubbleshooter.net playing the game and on irc vie chatzilla and it just crashed

we get about 100k \N signatures a day.
we could turn this into a bug about bubbleshooter null signature crashes
awk -F\t '$1 ~ /\N/ {print $2}' 201004* | grep bubbleshoot | sort | uniq -c | sort -nr

or we could start trying to figure out the url's most frequently associated with null signatures, or we could do both ;-)
Here are overall top sites with null sigs

the last big chunk of null crashes the we diagnosed was anti-virus stuff IIRC. This time it might turn up something more flash related. We could also look at null crash differences between OOPP builds and non-OOPP to ensure we haven't tweaked the crash reporting system in a way that creates more null sigs.
which way should we take this bug or bugs?

the reporter in this case had a outdated flash version and the boubleshooter site/game is a flash game, fwiw
I think Bubbleshooter is way too specific. Let's see if we can find a reproducible test case for generating a null crash sig with Flash (in windows I assume). It looks like facebook/farmville or chatroulette may be a good place to start and if so, we can see if OOPP can help with it.

We've had plenty of Flash crashes in the past that corrupt the heap so badly that we can't write out a valid minidump. I don't think there's much we can do about that aside from ship OOPP.

From CrashKill meeting: make it easy to search for these and see user comments associated as they are often telling.

In the current UI for search results and top crashers, we use a special code out of band with the signature parameter to control this.
This extra param is missing_sig... so something like:
missing_sig=None
missing_sig=Empty
I think these constants are in http://code.google.com/p/socorro/source/browse/trunk/webapp-php/application/libraries/crash.php (code.google is down right now)

This might help a little - Bug 552088 - crash reports with email addresses but no comment don't all bubble up to the top of the "comments" tab.
Depends on: 552088

bp-0f7fbce5-30af-4309-8e5c-53ce92100520 has a processor note of "value too long for type character varying(255)" and signature

for some odd reason a few hangs appear in https://crash-stats.mozilla.com/report/list?version=Firefox%3A3.6.9pre&build_id=&query_search=signature&query_type=exact&query=&date=2010-08-12%2004%3A00%3A00&range_value=30&range_unit=days&hang_type=any&process_type=any&plugin_field=&plugin_query_type=&plugin_query=&do_query=&signature=&missing_sig=NULL&page=1 ... for example

Austin, Laura is this tracked in socorro ?

Comment 12•15 years ago

I think I might be able to guess why this is happening. That signature is 332 characters long and therefore won't fit in the column (signature character varying(255)).
Lars, do we want to do something like truncate excessively long signatures? Will the problem go away when we hook the front end up to HBase anyway?
Comment 13•15 years ago
|
||
hbase itself doesn't have a character limit on the values, so it wouldn't be a problem on that side.
Comment 14•15 years ago
|
||
Bug 564196 was supposed to have truncated signatures to fit in the database.
Comment 15•15 years ago
|
||
The code fix for truncating signatures was targeted for 1.7. I've verified that the code exists in that release. I can see that 1.7 was pushed to production on June 10th (Bug 571228). The offending crash has a date of May 20th.

This is still something we should do, I think, but it might make sense to create a separate, clearly described bug for that.
