Software


I decided that it really was time I upgraded my installation of WordPress from version 2.2.1. This is normally a really simple porcess, but not this time.

Rather than overwriting the existing installation, I always start afresh. I backed up the databases as usual, disabled all plugins, downloaded the latest version (2.9.2) and then proceeded to incoroprate my edits into the new version. I also copied across the theme and plugins.

However, when I tried to run the upgrade script, I got the following error logged in Apache’s error_log [notice] child pid 19836 exit signal Segmentation fault (11)

After speaking to my Hosting company, they advised that they had had a lot of compatibility problems with PHP 5.3.0 and advised downgrading to PHP 5.2.12 instead.

All is OK now

I have been asked to layout a newsletter for the local civic society as the usual person was too busy. Although I have an uninstalled copy of Microsoft Publisher somewhere, I had never used it before and wanted to find an open source alternative. Enter Scribus and GhostScript. In order to get this to work on Windows 2000, I also needed to download the GDI+ SDK.

Getting started was fairly simple, but in order to run the tutorials at docs.scribus.net I needed to download various ICC profiles and fonts

Simply extract the contents of the two ICC files into the /libs/profiles subdirectory of Scribus and extract the .ttf files from the Luxi fonts into your Fonts folder (Start>Settings>Control Panel>Fonts)

I was recently playing with Google’s webmaster tools and ran into a problem with my custom error page. Although I have had it set up for some time, it was apparently incorrectly configured. Google complained ‘We’ve detected that your 404 file (file not found) error page returns a status of 200 (Success) in the header. ” which means that the page was found and they’re not happy.

In order to troubleshoot this, I connected to my web server using telnet. This enabled me to see the exact data that Apache is delivering in reply to the request. This is what you need to do

  1. Open a Command prompt window (run cmd.exe on a PC)
  2. Connect to the web server (Apache) using telnet. If your web server does not run on port 80, then use the correct value. telnet mydomain.com 80
  3. Ask for the header of a non existent page by typing HEAD invalidpage.html HTTP/1.0. Although the cursor moves, NO TEXT WILL APPEAR ON THE SCREEN.
  4. Press the Enter key twice and wait for a reply

The reply you get should look something like this

HTTP/1.1 404 Not Found
Date: Fri, 30 Mar 2007 11:30:22 GMT

When I tested my site, I found that it was responding

HTTP/1.1 302 Found
Date: Fri, 30 Mar 2007 11:33:22 GMT
Server: Apache/1.3.27 (Unix) (Red-Hat/Linux) mod_ssl/2.8.12 OpenSSL/0.9.6b PHP/4.4.2
Location: http://xxx.xxx.xxx.xxx/404.html
Connection: close
Content-Type: text/html; charset=iso-8859-1

Connection to host lost.

So my server was returning a status code of 302 which is a temporary redirect. When Google followed this to the new location, it received the 200 status code as the ultimate file exists. I tried adding the line
<meta http-equiv="Status" content="404 Condition Intercepted" />
in the head section of my error file as suggested on another site, but it made no difference. The real problem was that I had failed to notice the comments in the Apache manual

Note that when you specify an ErrorDocument that points to a remote URL (ie. anything with a method such as http in front of it), Apache will send a redirect to the client to tell it where to find the document, even if the document ends up being on the same server. This has several implications, the most important being that the client will not receive the original error status code, but instead will receive a redirect status code. This in turn can confuse web robots and other clients which try to determine if a URL is valid using the status code.

I wanted to use the same error page for multiple domains hosted on my VPS and so had hardcoded the IP Address into the URL. The line in my Apache configuration file read ErrorDocument 404 http://xxx.xxx.xxx.xxx/404.html. I therefore changed it to ErrorDocument 404 /errorp/404.html and created an alias for /errorp/ Alias /errorp/ “/path/to/custom_errors/”. My custom error page now responds correctly :)

If you have to use http: in your Custom Error Page's definition, then you are better off using a redirect in a local file. This will preserve the error status code. Your local error file should look something like this

<HTML><HEAD>
<META http-equiv="refresh" content="0; URL=http://www.example.com">
</HEAD>
<div style="visibility:hidden">
;Lets insert some random text here in order to keep Microsoft Internet
;Explorer happy. In their wisdom, Microsoft have decided that any custom
;error page with less than five hundred and twelve characters of text
;in it will be totally ignored and they will display their Friendly HTTP Error
;message instead. This is detailed in knowledge base article Q294807
;at http://support.microsoft.com/default.aspx?scid=kb;en-us;Q294807
;Well, I think that that is enough from me for now or maybe I should
;just type a little bit more to make sure that I have typed enough...

gnulib is a collection of approximately 590 routines which allow programs to be built on a cross platform basis. These are files intended to be shared at the source level rather than being a library meant to be installed and linked against so, unlike most projects, Gnulib does not normally generate a source tarball distribution; instead, developers should just grab modules directly from the repository. (The full list of modules and their description can be found here.) If you are missing one of the modules, you will get an error along the lines of

./configure: gl_XALLOC: command not found

when running ./configure

There are several ways to get hold of a copy of the repository:

  1. If you have git installed, then use the command git clone git://git.sv.gnu.org/gnulib
  2. If you prefer the CVS-like frontend of ‘cogitocg clone git://git.sv.gnu.org/gnulib
  3. If you have tightly limited disk space and a fast network connection, then CVS checkouts are also supported:
    $ cvs -d :pserver:anoncvs@cvs.gnu.org:/cvsroot/gnulib login
    (Just hit Enter or Return when prompted for a password)
    $ cvs -d :pserver:anoncvs@cvs.gnu.org:/cvsroot/gnulib checkout gnulib
  4. Download a snapshot from GNU’s Savannah server using wget

Since Westhost’s platform has none of git, cogito or cvs installed by default, I used the final option to obtain a copy of gnulib.git-HEAD.tar.gz
In order to use gnulib, you will need to download the gnulib-tool script and then use this to install the required modules. Don’t forget that you will need to give gnulib-tool execution rights (chmod u+x gnulib-tool).

Glib is available from GTK by FTP. At the time of writing, the current version is 2.12.12

Download the source code

  • Connect to your server using PuTTY or some other SSH client
  • Connect to GTK’s FTP server by typing the command ftp ftp.gtk.org
  • Login using the username anonymous and password anon@
  • Change to the directory where the source code is stored cd /pub/glib/2.12/
  • Change the mode to binary by entering the command binary
  • Download the file using the command get glib-2.12.12.tar.gz
  • Also download the md5 checksum to verify the veracity of your download get glib-2.12.12.tar.gz.md5
  • Close your FTP session by typing quit
  • Having downloaded the source code, extract the files into a new directory by entering the command gunzip -c glib-2.12.12.tar.gz|tar x

Install dependencies

We need to download and install the libiconv and gettext libraries before we can build GLib. Also, since we do not have root access at Westhost, we need to tell all Linux packages to install to a different directory other than /usr/local. We do this by specifying

./configure --prefix=/usr/mylocal
NOTE: Create the directory /usr/mylocal if it does not already exist

Library Command Download Location
libiconv wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz
libiconv wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz.sig
gettext ftp ftp://mirrors.usc.edu/pub/gnu/gettext/gettext-0.16.tar.gz
gettext ftp ftp://mirrors.usc.edu/pub/gnu/gettext/gettext-0.16.tar.gz.sig

libiconv and gettext depend on each other, so we need to build libiconv then gettext and the rebuild libiconv.

Build libiconv

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz.sig
gunzip -c libiconv-1.11.tar.gz | tar x
cd libiconv-1.11
./configure --prefix=/usr/mylocal >log.config 2>err.config
Check err.config for errors
make >log.make 2>err.make
This will build with errors, so do not check err.make for errors
make install >log.install 2>err.install
cd ..

Build gettext

ftp mirrors.usc.edu
anonymous
anon@
cd pub/gnu/gettext
mode image
passive
get gettext-0.16.tar.gz
get gettext-0.16.tar.gz.sig
quit
gunzip -c gettext-0.16.tar.gz |tar x
cd gettext-0.16
./configure --prefix=/usr/mylocal >log.config 2>err.config
Check err.config for errors
make>log.make 2>err.make
Check err.make for errors
make install> log.install 2>err.install
Check err.install for errors

Rebuild libiconv

cd ../libiconv-1.11
make distclean
./configure --prefix=/usr/mylocal >log.config 2>err.config
Check err.config for errors
make>log.make 2>err.make
Check err.make for errors
make install> log.install 2>err.install
Check err.install for errors
libtool --dry-run --finish /usr/mylocal/lib
libtool --finish /usr/mylocal/lib
cd ..

Build the GLib library

  • Change into the new directory cd glib-2.12.12
  • Run autoconfigure to determine the build parameters ./configure --with-libiconv --prefix=/usr/mylocal >log.config 2>err.config
  • Check the err.config file for any errors
  • Build the library make >log.make 2>err.make
  • Check err.make for errors
  • Install the library make install >log.install 2>err.install

Errors we encountered

#error GNU libiconv not in use but included iconv.h is from libiconv

Added --with-libiconv to ./configure

warning: passing arg 2 of `g_async_queue_push’ discards qualifiers from pointer target type

This is only a warning and so can be ignored
