Posting SVN commits to an IRC channel

Everybody may be aware of svn mailers that post commit logs to a mailing list or several email address. I found more useful to have a notification on my favourite IRC channel.

For people interested in IRC notification of SVN commits, here is a python script that will do the trick.


#!/usr/bin/python
import sys
from irclib import *

 class SVNBot(SimpleIRCClient):
    def __init__(self, server, port, target, repo, rev,
author, log):
        SimpleIRCClient.__init__(self)

         self.target = target
        self.repo = repo
        self.rev = rev
        self.author = author
        self.log = log
        self.msg = 'new commit on ' + repo + ' r' + rev + '
by ' + author + ': ' + log
        self.connect(server, port, 'svnbot')

     def on_nicknameinuse(self, c, e):
        c.nick(c.get_nickname() + '_')
    
    def on_welcome(self, c, e):
        if (is_channel(self.target)):
            self.connection.join(self.target)
        else:
            self.connection.notice(self.target, self.msg)
            self.connection.quit()

     def on_join(self, c, e):
        nick = nm_to_n(e.source())
        if nick == c.get_nickname():
            self.connection.notice(self.target, self.msg)
        self.connection.quit()

     def on_quit(self, c, e):
        nick = nm_to_n(e.source())
        if nick == c.get_nickname():
            self.connection.disconnect()
            sys.exit(0)

 def main():
    if len(sys.argv) != 7:
        print 'Usage: ' + sys.argv[0] + ' <server[:port]>
<target> <repo> <revnum> <author> <log>'
        sys.exit(1)

     s = sys.argv[1].split(':', 1)
    server = s[0]
    if len(s) == 2:
        try:
            port = int(s[1])
        except ValueError:
            print 'Error: Erroneous port.'
            sys.exit(1)
    
    else:
        port = 6667
    target = sys.argv[2]
    repo = sys.argv[3]
    revnum = sys.argv[4]
    author = sys.argv[5]
    log = sys.argv[6]
    bot = SVNBot(server, port, target, repo, revnum, author,
log)
    bot.start()

 if __name__ == '__main__':
    main()

This script should be callable from the hooks/post-commit file as follow:


REPOS="$1"
REV="$2"
AUTHOR=`/usr/bin/svnlook author "$REPOS"`
LOG=`/usr/bin/svnlook log "$REPOS"`
/usr/local/bin/svnbot.py "irc.server" "#irc.chan" "$REPOS"
"$REV" "$AUTHOR" "$LOG"

Now, happy commits!

nall! notify almost everything on the system tray

I finally released a decent tarball of nall, a tool i use for several months, and i noticed that some people really waited for such a tool to monitor various networked resources a simple way. However, nall's current spawn'n'reap model is not very smart,so i may improve it in the future.

python is cool: chapter 0

I finally rewrote a program (previously wrote in C) in the python language. I like it, mainly for it's well documented API and the way we can have both the functionnal and object language style. I took to me less than 12 hours to complete the program i made in 3 days of C, having not any knowledge of Python but a book. I'ts really cool.

vala tutorial: chapter 0

after about 8 years of C and bourne, i finally decided to learn a descent language. and by learn, i mean learn from the beginning, as a baby. making things clean, trying to forget crappy things i made in the past. So, i decided to choose vala for testing my fresh baby brain. This first post on vala is be the beginning of a step by step introduction to this language for people who know C or C++.

first, read This Hello World in Vala

Here is a variant, which goal is to demonstrate how to use program's arguments, and how to get an array's length:

using GLib; public class Tutorial.CommandLineArgs : GLib.Object { public static void main(string[] args) { for (uint i=1; i< args.length; i++) stdout.printf("Hello, %s. ",args[i]); stdout.printf("My name is %s\n", args[0]); } }

Here you see the declaration of an array of strings which i called args, another declaration: an unsigned integer variable named i. Then you see the length member of the array type. Finally you see how to acces to an array's cell.

Question from the baby: how to get the real basename of args[0], having knowledge of basename() from <libgen.h> or g_path_get_basename() from GLib ? Reply: to acces g_path_get_basename() from GLib, Vala has this naming convetion: GLib.Path.get_basename(). Now it's up to you to make a better hello people program.

vps experience

After the succcessful vserver experience for virtualizing asterisks and freepbx, i am now switching to the VPS technology provided by Positive software. The advantage is mainly that they provide a web interface to generete guest OSes. The cons is that it is not free for commercial purposes. see you later for more infos.

why just not extending HTML ?

After playing whith GLADE for Gtk+ apps i still think xhtml is the easyest way to set up a quick form based graphial interface. So i am looking for a HTML to Glade converter or somthing like that. years ago I heard the XFroms would appear in several years since it is an W3C proposal. But anyway... we are still waiting. So, why just not simply extend xhtml for form based apps ? you know, many new widgets would be useful, like:


<date>01/01/1970</date>
<knob start="0" end="100"></>
<slider pos="vertical" start="0", end="100"></>
<menu class="main">
<item action="edit.php" target="new" >Edit</entry>
<item action="prefs.php"
target="new">Preferences</entry>
</menu>

virtualizing asterisk

i'm on making asterisk boxes inside linux virtual servers. Frank told about the linux vserver patch and.. wow this is really nice and simple to use. I installed a fresh etch into my old p500 and installed the vserver kernel from etch.. simple. now here are the commands to create a full-featured vserver guest having a debian etch:


# uname -a
linux-image-vserver-686 blah...
# apt-get install util-vserver
[...]
# vserver server1 build -m debootstrap -- -d etch
[coffe men...]
# vserver server1 start
[see init process]
# vserver server1 enter
#_

and voilà!

Sourceforge is really bad to me

Well, i decided to abandon releases on sourceforge.net since their release manager is really a crap. Also, i can't login anymore to sourceforge.net since they don't have correct no-cache meta tags on their login pages. So i switched to nongnu.org and yes, it is far better! You can see libspopc on nongnu.org's savannah.

awffull color patch

i patched awffull to give it ability to read user's personal colors in awffull.conf and draw personalized charts. The patch has been made on awffull-3.02-beta2 but Steve McInerney have just released the 3.02 version today (not beta).
He told me he will include the patch for the next release (3.03). If you can't wait, you can get my patch here (applies on 3.02-beta2).

Update: this early patch gave not full color customization, the next official awffull will handle it better.

webalizer : the contribs

several years ago, i patched the well known webalizer (2.01-10) in order to give it user defined colors capabilities. I recently found it on Brad Barrett's ftp site and discovered there are many unknown other useful contribs that extends the webalizer: check the webalizer contrib subdir on Brad Barrett's ftp site.
