A repository is exactly like a file system, but a file system that keeps all modifications.
Everybody can make a copy of the repository on his hard disk by using the following command:
$ svn checkout https://gambas.svn.sourceforge.net/svnroot/gambas/2.0/trunk/
But if you want to do development or translations for Gambas, then you need a write access to the repository.
To get that, just create a user account on sourceforge.net, and ask me to grant a write access to the user you just have created.
Each time anything is changed in the repository, the revision number is incremented, and a revision log is attached to it. The revision log is edited by the person doing the modification.
All is done with the svn command.
When you commit, you must specify the editor used for editing the revision log in the $EDITOR environment variable. For example:
$ EDITOR=gedit svn commit
![]() | Note that you cannot modify a revision log after the commit. It seems that sourceforge has disabled this feature. So, be careful! |
I want to have a standard way to write commit messages, so that ChangeLog can be almost automatically generated.
The format is the following:
Slots are the name of the component in uppercase, or one of the following:
If a changelog modification is more than one line, you must use a two space indent.
Void lines are ignored.
All other lines won't go into the changelog.
I did this thing, and this won't go into the changelog. [GB.QT] * BUG: I fixed this bug. * NEW: I made this very long modification.... and it takes more than one line to write it. This won't go into the chanlog too. [GB.SDL] * BUG: What an awful bug! [GB.GTK] * NEW: I finally finished the component :-)
Please follow this scheme. It would be cool...
There is a mailing-list that gets a mail each time somebody (usually me) commits a new revision. So this way you always know if you have the last revision on your hardisk or not.
To subscribe to this mailing-list, go to the mailing-list page on the web site.
To get the state of your repository copy, run the svn status command.
Each state is described with one or more letter:
You must tell subversion if you add, delete, rename or move a file. You do that with the commands:
![]() | Forgetting to use svn add is a common mistake. I know what I'm talking about :-) |
Somebody can modify a file in the repository, while you have modified the same file on your hardisk. This is a conflict, and svn will tell you when running svn update, or the svn status command.
Each time there is conflict, svn tries to solve it automatically, by merging your own changes with the changes made by other people.
If the merge succeed, your will get a file with a 'G' state character.
If the merge didn't succeed, your will get a file with a 'C' state character. Then you will have to solve the conflict by hand:
Normally there is no risk, as everything is archived, and so you can always go back in time.
Moreover, if you work on a Gambas project inside the repository, the development environment can deal with all svn command for you. Go to the versioning tab in the project property dialog, and you will find buttons that allow you to update the project, commit it, and cancel your modifications.
If you have made something weird, you can use the svn revert command. It will revert you local copy to the state of the last checkout or update.
