[DRE-maint] Bug#941707: ruby-odbc: [RubyODBC]Cannot allocate SQLHENV (ODBC::Error)

[Martin Dorey]

Package: ruby-odbc
Version: 0.99998-1+b1
Severity: normal
Tags: patch

Dear Maintainer,

ruby-odbc does this, at least for me, on Buster:

martind at neutrino:~$ ruby -we 'require "odbc"; ODBC.drivers()'
Traceback (most recent call last):
	1: from -e:1:in `<main>'
-e:1:in `drivers': INTERN (0) [RubyODBC]Cannot allocate SQLHENV (ODBC::Error)
martind at neutrino:~$

The same test on the same configuration on Stretch is silent:

martind at scoot:~$ ruby -we 'require "odbc"; ODBC.drivers()'
martind at scoot:~$

I do have non-default /etc/odbc{,inst}.ini files but removing them doesn't affect this test.

Buoyed by a mention of Stretch here:

https://bugs.launchpad.net/raspbian/+bug/1832778

... I thought that maybe this blast from the past could have come back:

http://opensysblog.directorioc.net/2013/07/rubyodbccannot-allocate-sqlhenv.html

The change log in:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=889025

... included:

   * Refresh 001extconf_dlopen.patch

Reverting that fixed the problem.
These are the steps I took:

aptitude source ruby-odbc
sudo aptitude install gem2deb
tar --xz -xf ruby-odbc_0.99998-1.debian.tar.xz
debian/patches/ext_enable_dlopen.patch
cd ruby-odbc-0.99998/
patch -p1 -R < ../debian/patches/ext_enable_dlopen.patch
dpkg-buildpackage -b -nc -uc
sudo dpkg -i ../ruby-odbc_0.99998-1_amd64.deb

I can't say I understand why Debian would have to disable dlopen here.
But the package appears unusuable without that, for me.
