Certification Report for patch 3281, 3285 and 3286

• Certifier: Alejandro Álvarez Ayllón
• SA3 Partner: CERN

General Background

The patch 3286 fixes the reported bug #37572 about lcg-infosites. However, the same bug existed in the 64 bits version of gLite 3.1, and in gLite 3.2, so the patches 3285 and 3281 fix it respectively.

I reproduced the bug, and tested the patch in:

• vtb-generic-112 gLite 3.1 SL4 32 bits (Patch 3286)
• vtb-generic-113 gLite 3.2 SL5 64 bits (Patch 3281)
• vtb-generic-115 gLite 3.1 SL4 64 bits (Patch 3285)

For all of them the procedure has been the same:

1. Set the value of $LCG_GFAL_INFOSYS to lxbra2305.cern.ch:2170,lxbra2306.cern.ch:2170 (two servers separated by a comma)
2. Run lcg-infosites ce --vo dteam to reproduce the bug
3. Install the patch: ./AE_getpatch.sh 328*
4. Run again lcg-infosites ce --vo dteam and check if works

In all the cases, lcg-infosites before the update didn't add an end-of-line after the error message.

As suggested by Andrew, I have also checked what happen when the first server, or both, fail.

First fails

Again, the error messages are written in the standard error stream, and the exit code is 0.
