Bug #: 7172
Summary: Data Persistency
Classification: Unclassified
Change sponsored?: ---
Product: Koha
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: P1 - high
Component: Architecture, internals, and plumbing

We need to fix up the code throughout the system to be able to handle data
faster-than-CGI processors like Plack, FastCGI or mod_perl. At this time, most
of Koha can run okay, but when errors happen, they crash HARD. Some issues
than need attention:
nested subroutines: mod_perl, and I think other systems, turn each script into
a subroutine. If you have subroutines in subroutines (as we do in C4 and some
of the scripts), and an inner subroutine modifies a variable declared outside
in the outer subroutine, you will get an error "variable will not stay shared".
This can sometimes (always?) be fixed by using "our" instead of "my". Or
using better coding practices :)
memory leaks: some memory may not be released, so a persistent engine could
bloat over time.
other issues may come up, as well.
