Bug#877720: libdbd-firebird-perl: bad conversion of numerics between -1 and 0

[Damyan Ivanov]

Package: libdbd-firebird-perl
Version: 0.50
Severity: grave
Tags: upstream patch fixed-upstream
Justification: causes non-serious data loss

When fetching numeric data bwtween -1 and 0, DBD::Firebird messes with 
the conversion from the format the firebird uses to the string that is 
passed to upper layers causing data loss.

This was fixed upstream in https://github.com/mariuz/perl-dbd-firebird/commit/b4fad5d264abafeb26e1333b74f6a5c2f75f4869

It seems to me the non-working code was first released in version 0.50 
upstream, so every Debian release is affected.

An updated test at 
https://github.com/mariuz/perl-dbd-firebird/blob/master/t/92-bigdecimal_read.t 
demonstrates the issue.

I plan to fix this in unstable by upgrading the package to the newest 
upstream release, and probably stable by backporting the fix.


Cheers,
