Saving to Request.prof_file raises DataError for paths longer than 251 characters

[smcoll]

The decorator is raising a DataError when it tries to store the path of a .prof for any path greater than 251 characters, since the Request.prof_file is 100 300 characters by default, and the filename itself is 41 or 49 characters.

django.db.utils.DataError: value too long for type character varying(300)

In my case, the project path for local development was more than 60 characters at a time the column was 100 chars, which meant the file was saving to disk, but no profile data was being saved to the database. We probably want to at least save the other profile data and log an error, otherwise a long file path breaks profiling altogether.

@smcoll If my memory serves me correct I think you can specify a path to store the .prof files.

One suggestion is to create an symbolic link in your environment to get around the 100 character limit.

@avelis that will do for now, but it'd be reasonable to increase the column length, right? i'm making a PR now.

this issue can be closed since #203 is merged

@srinivasreddy no, #203 increased the limit by 200 characters, but the underlying issue is still the same. It needs to be determined how silk will handle a case where a binary cannot be saved.
