Hello Sébastien,

sage calls GLPK as a library. So in general it does not depend on parsing output.

If some tests in sage make invalid assumptions about terminal output, they should be fixed in sage.

The GLPK output is not meant to be a stable API.

Please, close the Debian bug as invalid.

Regards

Heinrich

Dear GLPK maintainer,

I received the attached bug report and patch for the glpk package in Debian.

What’s your take on this? Should I apply the patch, or is this something that
should better be fixed at the sagemath level?

Best,

P.S.: please keep all addresses in CC when replying.

sagemath tests

Source: glpk
Version: 4.65-1
Severity: normal
Tags: patch

Hi there,

since version 4.65 glpk started to frequently print the message "Long-step dual simplex will be used", leading to many failed tests for sagemath and sagemath failing to build. Not sure if it's a bug in glpk but it seems to me it shouldn't print this. Could you maybe deactivate the messages to allow sagemath to build?

Best,
Tobias
