Hera Try Server Administration

Try Server (Front node)

• To connect to the tryserver do it through ssh to hera.senecac.on.ca
• The folders "cgi-bin", "html" and "patches" are aliased to show to the public
• The folders "patches_test" and "builds" are not yet available

Master (Front node)

• The basedir of the buildbot is the home directory, therefore "buildobt restart ."
• Run "perl process_changes_test.pl" to read the patches from the "tryserver" and notify of changes to the master. Every 2 minutes a cronjob takes care of running this command. Patches get copied to "patches" or "patches_test" (this may be unified later on)

Slaves

NOTE: For any account credentials talk with Dave Humphrey
NOTE2: The Mac slave has the slave in /opt/slave and it is owned by armenzg account, shall we create a "buildslave" account to own it?

Connecting

• LINUX
  • You have to connect first to the front node and the "ssh buildslave@vmlinux1"
  • You can also connect with VMware to hera.senecac.on.ca:1904
• MAC
  • You connect directly with ssh to a specific IP (to be added) and with your individual account
• WINDOWS
  • Use "Remote Desktop Connection" (comes with Windows) to connect to hera.senecac.on.ca:31389 with buildslave account

Creation

• LINUX
  • buildbot create-slave slave hera:12345 lin1 lin1
• MAC
  • /usr/local/bin/buildbot create-slave /tmp/slave hera:12345 mac1 mac1 (right not the slave is on /Users/adam.delyea/buildbot/slave -- Is /tmp/slave a good place??)
• WINDOWS
  • Run c:\mozilla-build\start-msvc8.bat to start
  • /c/Python24/scripts/buildbot create-slave /c/slave/ hera:12345 win1 win1

Start

• LINUX
  • buildbot start ~/slave
• MAC
  • /usr/local/bin/buildbot start /Users/adam.delyea/buildbot/slave (the location should be changed)
• WINDOWS ("twistd.pid" does not get created)
  • /c/Python24/scripts/buildbot start /c/slave/ //make note of the ampersand symbol, it puts the task in the background

Restart

• LINUX
  • buildbot restart ~/slave
• MAC
  • /usr/local/bin/buildbot restart /Users/adam.delyea/buildbot/slave
• WINDOWS - Kill it and then start it again since twistd.pid has not been generated
  • ps aux
  • Look for the ID for /c/Python24/scr <--- The column does not reach to show the complete path
  • kill 34567 //Put the correct ID
  • Check the section before to start the slave

Left to be implemented

• Install Windows Vista SDK on the windows machine - [1]
• Use incron instead cronjob to run "perl proccesschanges_test.pl" in the buildmaster machine
• Add the ssh keys to the tryserver account

News

• Created universal patch for testing purposes since it "always" gets applied

Known Errors/Issues

• In the WINDOWS machines be sure to do not create a slave in a path that has spaces or will fail client.mk#427
• Builbot Bug 155 and Builbot Bug 85 - You have to restart the master if you see in the waterfall view machines that are IDLE but with pending builds

Fixed

• Fixed in Windows machine - client.mk:427: *** The mozilla directory cannot be located in a path with spaces.. Stop. [2]
• Fixed in Mac machine - We have added to buildbotcustom/env.py the PATH environment value because it was missing /opt/local/bin checking for GLIB - version >= 1.2.0... no [3]
