RabbitVCS on Ubuntu GNOME 14.04 Trusty Tahr

Filed under: Linux — Tags: , , , , , , , , , — Christopher Kramer @ 11:38

I installed RabbtVCS on Ubuntu GNOME 14.04 Trusty Tahr from the Ubuntu repositories (rabbitvcs-nautilus) and it did not integrate into Nautilus. It also seemed to cause other strange effects (mouse wheel not working any more, …?).

Installing the latest version from the RabbitVCS PPA fixed all this:

sudo add-apt-repository ppa:rabbitvcs/ppa
sudo apt-get update
sudo apt-get install rabbitvcs-nautilus3

Hope this saves somebody half an hour figuring out how to solve this 😉

Recommendation

Try my Open Source PHP visitor analytics script CrazyStat.

TortoiseSVN painfully slow (Log)

Filed under: Windows — Tags: , , , , , , — Christopher Kramer @ 21:14

I had a problem with TortoiseSVN: Sometimes it behaved painfully slow. Especially when I wanted to view the log of CrazyStat’s svn repository, it took about 10 minutes (!) to show it. First I thought the problem was caused by the Sourceforge servers, but then I realized that other svn clients did not have the same problem. I tried several things and the solution finally was quite simple and even listed the the TortoiseSVN FAQ:

Browsing very slow in explorer and file/open dialog.

If you have mapped network drives which are not resolved, either because the drive is inaccessible, or you have not logged in, file browsing may become unresponsive while Windows tries unsuccessfully to access the drive. Either unmap the drive or ensure that it can be accessed

 

I first did not think that this was my problem as I did not experience slow browsing in explorer or file/open dialog. But after I unmapped all unresolved network drives, it worked great again.

By the way, I’d recommend TortoiseSVN to anybody who is searching for a windows svn client. I have not seen any other client that powerful yet simple.

I hope this might be helpful for somebody who has the same problem.

Public SVN for CrazyStat

Filed under: CrazyStat — Tags: , , , — Christopher Kramer @ 23:12

Finally, CrazyStat’s SVN has gone public!

CrazyStat uses Sourceforge for SVN hosting. You can browse it here:

https://sourceforge.net/p/crazystat/code/

To checkout the current development version of CrazyStat, use one of these:

  • SVN over HTTP protocol:
    svn checkout http://svn.code.sf.net/p/crazystat/code/trunk crazystat-code
  • SVN protocol:
    svn checkout svn://svn.code.sf.net/p/crazystat/code/trunk crazystat-code

In the SVN repository, you can find the current CrazyStat 1.71 development version (in the trunk) along with 1.71 beta1 and beta2.

You can also read the commit logs to see what is going on with CrazyStat development.

In case you want to test the upcoming CrazyStat version 1.71, I’d recommend checking out the current development version from the trunk. Please let me know if you find any bugs or issues with the current development version (which will soon become RC1…).

This is part of my plans to make development of CrazyStat more open.

Greetings!

Subversion (SVN): Permanently remove files from repository (history)

Filed under: Linux,Server Administration — Tags: , , , , , , — Christopher Kramer @ 20:02

As I am about to make CrazyStat’s subversion repository public, I checked whether there is anything in there that is not suitable to be made public. I stumbled upon some logfiles which I had once used for testing and accidentally commited to the repo. These logfiles contained private data and therefore, I needed to remove them from the history before making the repository public.

And that is how it can be done:

As SVN has no ‘obliterate’ command yet (see feature request here), you need to perform the following steps:

  1. Make sure nobody else uses the repo at the time
  2. Dump your repository to a dumpfile
  3. Filter the dumpfile (remove the files you do not want to be in there anymore)
  4. Create a new repository
  5. Import the dumpfile in the new repository
  6. Replace the old with the new repository
  7. Check it
  8. Clean up

These steps in detail:

Step 1: Make sure nobody else uses the repo at the time

I think the easiest way would be to remove write-permissions from the repository-folder. E.g. if you access your svn through apache, just chown it from www-data to root and nobody should be able to write anymore:

chown -R root:root /var/svn/REPOSITORY

Step 2: Dump your repository to a dumpfile

svnadmin dump /var/svn/REPOSITORY > dumpfile

Step 3: Filter the dumpfile

svndumpfilter exclude /path/of/file/to/remove < dumpfile > newdumpfile

This will remove the file “/path/of/file/to/remove”. You can remove multiple files at a time like this:

svndumpfilter exclude file1 file2 < dumpfile > newdumpfile

I did not find any way to use wildcards, though. Let me know in case you find anything.

Update: Thanks to the comment by Florian! Here is the way to use wildcards:

svndumpfilter exclude –pattern "*.OLD" < dumpfile > newdumpfile

Florian also pointed us to a documentation of svndumpfilter which might be helpful for some of you.

Step 4: Create a new repository

svnadmin create /var/svn/REPOSITORY_NEW

Familiar, right? 😉

Step 5: Import the dumpfile in the new repository

svnadmin load /var/svn/REPOSITORY_NEW < newdumpfile

Step 6: Replace the old with the new repository

chown -R www-data:www-data /var/svn/REPOSITORY_NEW
mv /var/svn/REPOSITORY /var/svn/REPOSITORY_OLD
mv /var/svn/REPOSITORY_NEW /var/svn/REPOSITORY

In the first line I also changed the file owner and group to www-data to make the new repository accessible for apache. In case you do not use apache (e.g. svnserve), skip the line or change the file owner and group to your needs (see what the owner of the old repo was using “ls -l /var/svn” ).

Step 7: Check it

You update your working copy (shouldn’t change anything). But when you browse your history and want to see one of the files you removed, you will get an error that the file could not be found.
You might want to make a fresh checkout and a commit to see whether everything still works as expected…

Step 8: Clean up

In case everything went well, you can delete a couple of things:

rm -R dumpfile newdumpfile /var/svn/REPOSITORY_OLD

 

Deleting old revisions

I also found a useful blog post on how to delete old revisions and only keep new ones. Some users might prefer this option if it is not a single file they want to get rid of but complete old revisions.

 

By the way, the CrazyStat SVN repository will be publicly available soon…

Hope somebody finds anything of this useful.

CrazyStat development to get more open (Bugtracker, Wiki, FAQ, SVN)

Filed under: CrazyStat — Tags: , , , , , , — Christopher Kramer @ 15:17

Bug Tracker

I plan to start a public bug tracker for CrazyStat. I think this makes it easier for you to report bugs and feature requests and easier for me to manage those. I also plan a way so you can vote for new features.

Please let me know what your favourite bug tracker is. At the moment I favor redmine, but I’m not sure yet. Redmine also includes a nice wiki and project planning capabilities.

FAQ Script

Another idea of mine is to use a FAQ-script for CrazyStat. This makes asking and answering questions a lot easier. Some scripts can also handle translations which would be a great help to create FAQ in multiple languages. At the moment I think phpMyFAQ is the best solution for CrazyStat as it

  • supports multiple languages
  • supports community asking, answering and translation but also moderation and anti-spam
  • can export the FAQ into PDF/XHTML so it can be shipped in static format with CrazyStat as it is at the moment

If you have any good/bad experience with any FAQ script please let me know.

Of course it would be perfect if bug tracker, wiki and FAQ would be nicely integrated.

Public SVN

At the moment I develop CrazyStat in a SVN which is private only, but I think to make the development of CrazyStat more open, it will be necessary to open the SVN. Somebody proposed to use git, but I think at the moment git does not offer much that CrazyStat development needs compared to what SVN offers. Let me know if you disagree.

Bulletin Board / Forum

Some discussion around open-source software like user support might be more suitable to be done on a forum instead of a bugtracker or wiki. Of course phpBB is classic here, I would also consider something that is tightly integrated with the other software (bugtracker etc.).

Sourceforge project?

Somebody also proposed that I should open a sourceforge project for CrazyStat. I really like sourceforge and I think that might be a good idea, although I also love having full control over all the systems I use. But I think by opening a sourcforge project, I might get all those tools I discuss here quite easily and well integrated.

Update: I opened a sourforge project for CrazyStat now. Not much on there up to now, though. I think I will use Sourceforge for SVN, but I am not sure about the other tools. Although they are integrated nicely, they are also very limited in functionality.

Your feedback

Please let me know what tools you think an open source project like CrazyStat needs, which ones you favour and so on.
