Sysadmin/DeveloperAccessForRuleWriting

Writing rules for the conversion from svn to git requires you to download the whole svn repository. The size of that is 65GB. This is a problem for a lot of our developers. Hence we have setup 3 servers which can be used for the rule writing.

The 3 servers are identical in setup. Every registered KDE developers has access to all 3 servers with the keys you have setup on identity.kde.org.

This document assumes you are familiar with the rule writing. A good document to learn more about that can be found at http://techbase.kde.org/Projects/MoveToGit/UsingSvn2Git

Info about the servers

huey.kde.org

 Dual core AMD Opteron(tm) Processor 248, 4GB internal memory
 ssh [email protected]
 

dewey.kde.org

 Hexa core, 6GB internal memory
 ssh [email protected]

louie.kde.org

 Quad core, 512MB internal memory (can be expanded as we need it)
 ssh [email protected] -p22308

Remarks

• The ssh account name is git. Login with ssh [email protected]
• You share the account with all developers, for example don't install your favorite .vimrc as that affects all developers.
• Don't run any applications because you want to. IRC Bouncers for example.
• Use it for the rule writing. Everything else is wrong.
• Create a folder named after your identity.kde.org username and only work in there.
• We have made agreements about all this with the donors. If you violate the intended usage, we risk losing the machine.

The setup

• svn-all-fast-export is installed into the distro and is from Oct 18th. If a bug is fixed and you need it, drop sysadmin a note and we will start the sequence to update it. Example usage:

 svn-all-fast-export --add-metadata --identity-map /home/gitmaster/kde-ruleset/account-map \
 --rules /home/gitmaster/kde-ruleset/soprano-rules /home/gitmaster/svn/

• the svn repo can be queried in the gitmaster home directory. For example:

svn log -v --stop-on-copy file:///home/gitmaster/svn/trunk/extragear/utils/rsibreak 

(please note that there is no physical file on the disk located at /home/gitmaster/svn/trunk/extragear/utils/rsibreak, svn automatically recognizes it is a repository).

• the svn repo is updated every 4 hours.
• if you need rules, you can find them in: /home/gitmaster/kde-ruleset, this is read-only, so copy them over to your personal folder and work on them. When done, scp your personal folder to your own computer and commit to git from there.
• the rules are updated every 4 hours.

Tip

Be aware that "-P 22308" only applied to louie but not the other two servers which use the default ssh port.

• You can scp your personal folder to your computer with the following command executed from your own computer:

 scp -P 22308 -r [email protected]:username folder-from-louie
 -P 22308 is only needed for louie, otherwise leave it out
 replace 'username' with your svn username (the folder you created on the server)
 replace 'folder-from-louie' with folder name you like on your computer.

• You can also scp your personal folder from your computer to the server with the following command executed from your own computer:

 scp -P 22308 -r folder-to-louie [email protected]:username
 -P 22308 is only needed for louie, otherwise leave it out
 replace 'username' with your svn username (the folder you created on the server)
 replace 'folder-to-louie' with folder name you have on your computer.
