Its full size is currently 65GB, which is a problem for a lot of our developers. Hence we have setup a server which can be used for the rule writing (used to be three). |

| 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.

| ==Remarks==
| |
| | |
| *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==
| | * 23 May 2011: huey has been decommissioned from svn2git duties. It's now used for other tasks within KDE. |
| * 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: | | * 23 June 2012: louie has been returned to the hoster. |
| svn-all-fast-export --add-metadata --identity-map /home/gitmaster/kde-ruleset/account-map \
| | * 2015: dewey has been returned to the hoster. No machines now provide this service as the conversion from SVN to Git is essentially complete. |
| --rules /home/gitmaster/kde-ruleset/soprano-rules /home/gitmaster/svn/
| |
| | |
| * If anything doesn't work and you are unable to figure out how try rerunning the conversion with the "--debug-rules" option.
| |
| svn-all-fast-export --add-metadata --identity-map /home/gitmaster/kde-ruleset/account-map \
| |
| --rules /home/gitmaster/kde-ruleset/soprano-rules --debug-rules /home/gitmaster/svn/
| |
| This will print information about what rule matched for each matched file/directory.
| |
| | |
| * 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 couple minutes. | |
| * 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.
| |
| * before starting a conversion, '''please''' check <tt>top</tt> to see if there is one already running. If two conversions run at the same time, both take more than twice to finish.
| |
| | |
| ==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:
| |
| | |
| -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:
| |
| | |
| -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.
