Merl added a comment to T121094: Throttling linkwatcher tool user as it is consuming 100% CPU.

Because my bot (dbuser s51826) also runs queries on linkwatcher_linklog if have checked statistics of my script. Mainly to exclude a deadlock problem or table locks caused by my script.

Btw: i am running funtoo/gentoo on my two year old laptop and emerging jdk8 with a clean compile cache uses about 6GB of ram, 7 GB temp space, but completes within 40 minutes and not 3.5 hours as mentioned in T121020#1870527

Are there any plans to support ubuntu 16.04 as sge execution nodes next year? If so the easiest solution would be to keep the ssl force exception for labs until this is available at tools.

Merl added a comment to T110994: SGE queues all overloaded / jobs not submitting although load averages are low.
np_load_avg=1.810000 (= 0.060000 + 0.50 * 14.000000 with nproc=4) >= 1.75
= np_load_avg +  job_load_adjustments * [weight number of jobs started in the last 7,5 Minutes]

0,5 is job_load_adjustments shown in "qconf -ssconf"
14 is the sum of a new job number factor. If a new job is started is increased by 1. This value will decrease within 7.5 minutes (load_adjustment_decay_time) to 0 for each job. The sum of all these [0..1] values for jobs started in the last 7,5 Minutes is 14 in this case.

Merl added a comment to T105794: Insecure POST traffic.

I am a java expert. And i am using a libary which normally needs java 1.8. I rewrote some parts, so that i can use the libary with java 1.7 on labs.
Problem is that this library in this limited rewrite version does not know ssl protocol, but i have added a trigger which adds ssl support when getting a redirect answer from server.
This was quite simply the implement, but rewriting the whole code the have full ssl support with java 1.7 is imo too much unnecessary work.
The first http request of my bot is always a sitematrix request on meta and then a http siteinfo request on local wikis. While doing these first requests the bot changes to https. So when doing the login action later my bot is already using https.
