Subversion client hangs after post-commit

I had been hit by this problem since I setup Subversion on Ubuntu in January. The svnserve was properly invoked on Ubuntu server but whenever any svn client was trying to commit something back to the server, the client would hang for hours before it prompted an error: “Connection reset by peers.”

I searched all the Subversion and Ubuntu forums but could not find any solution to my problem. In the past months, I tried to identify the source of the problem and even tried many solutions suggested by people on these forums but the problem persisted. I had been committing to svn server with post commit email notification turned off and lost quite a number of post commit message. I used to keep track of changes by these email notification.

Yesterdat, I was trying my luck again and I accidentally noticed sendmail and sendmail-mta were called after commit. A look into syslog confirmed that sendmail process was put into sleep by some unknown reason. Failing to identify the cause, I removed sendmail and related packages from my Ubuntu server and installed Exim4. It is claimed to be easier to installed and configured than sendmail. The problem diminished after I got exim4 up and running. Now I am able to receive post commit email notification after every svn commit. Every commit takes a few seconds to complete after this. Problem resolved.

SVN setup

I’ve finally found time to setup svn at my home net after so many months. My svn server was down when my previous Linux box was down with a dead hard disk last year. The setup was quite a brisk. I had everything installed and configured last night. The test for remote access using a url was successful. I could import, checkout and check in. Because it was already late, about 1AM, I felt rather tire and went to bed.

This morning, I hacked some codes to provide a rather informative post commit email notification. All are done except the check in will stall. It takes a long time (and possibly hang!). I have yet to fully test before I begin my development project again.

Ubuntu Feisty Fawn

A few months ago, when fornax‘s hard disk was dead, I upgraded it from 40GB to 160GB and installed Debian Etch. Debian Etch has once again boosted my confidence about Linux. The graphical desktop was working up to my expectation. It could support up to 1280 x 1024 resolution! Upgrading Debian is easier compared to other Linux distros like SuSE, RedHat and etc. Actually, I quite like Debian to power fornax as an alternative development platform and also for some general purpose computing and testing purposes. I did not blog about my Debian installation a few months ago. I should blog about Ubuntu installation to record my experience.

Today, after some months, reinstalled fornax again with Ubuntu 7.04, code named Feisty Fawn. The UI is even more superb than Debian. Everything has been nicely done and packaged. To my surprised, I can run KDE applications from Gnome’s menu. This could not be done in Debian and some other Linux. How nice!

As the matter of fact, I did not like Gnome very much because KDE applications would not appear in Gome’s menu. Ubuntu has changed my perceptual experience about Gnome and once again Linux!

I find Ubuntu has more human touch than any other Linux distros. I also find that Ubuntu is very closely competitive with Mac OS X!

Really, I have download Ubuntu’s alternate install CD in June but I had never had a good reason to install Ubuntu over Debian. This morning, I had to install and configure many software, for instance, Subversion, apache and many other software development tools; it gave me a good reason to install Ubuntu. Not because Debian did not have all these software packages (Ubuntu is based on Debian), it was because I had to do most of the tasks which were almost like installing a fresh system.

Ubuntu’s installation is easier than Debian and faster. I had it up and running in less than 20 minutes!

Now, fornax has once again become my Linux development platform as well as SCM (Source Code Management) server. Oh! I run ktorrent for downloading movies as well. It really flies and sucking all the bandwidth. I have to stopped ktorrent whenever I want to work on Internet.
