installing Postgis 2.0 under Debian wheezy

2013-03-01T19:24:00Z

We’ll be using Postgis2.0 from UbuntuGIS, which has packages for a number of recent Ubuntu releases. Since Ubuntu precise has libc6 2.14 and Debian wheezy only 2.13 we fall back on Ubuntu oneiric for packages, which also has libc6 2.13.

However Postgis 2.0 in UbuntuGIS depends on a lot of llibraries which were in squeeze but live in wheezy under a higher version. Therefore we’ll install a lot of packages from Debian squeeze. Fortunately the libraries are versioned themselves and thus can be installed along the libraries from Debian wheezy.

Let’s go. Add the Debian squeeze sources:

# SRC="deb http://ftp.ch.debian.org/debian/ wheezy main"
# echo "$SRC" >> /etc/apt/sources.list

We’ll also add the security source, in case Debian releases a security update.

# SRC="deb http://ftp.ch.debian.org/debian/ wheezy main"
# echo "$SRC" >> /etc/apt/sources.list

You may want to replace ftp.ch.debian.org by a debian mirror nearer to you.

Now add the UbuntuGIS sources:

# SRC="deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu oneiric main"
# echo "$SRC" > /etc/apt/sources.list.d/ubuntugis.list

Now update and try to install postgis:

# apt-get update
# apt-get install postgresql-9.1-postgis

Create your database:

# sudo su
# su - postgres
$ psql postgres
postgres=# CREATE DATABASE your_db OWNER your_preferred_user:

Now add the postgis features to that database:

$ psql -d your_db -f /usr/share/postgresql/9.1/contrib/postgis-2.0/
$ psql -d your_db -f /usr/share/postgresql/9.1/contrib/postgis-2.0/spatial_ref_sys.sql

That should be it. Let’s hope it works.

A final warning: you are mixing multiple distributions here. This can lead to problems. Due to version conflicts upgrading packages can become very difficult.

Serving multiple WFS-T with TinyOWS

2013-02-25T20:16:00Z

Our favorite WFS-T server complement of UMN Mapserver is TinyOWS. We like the simplicity of it so much, that we packaged it for Ubuntu and added it to OSGeoLive. Installation is easy:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install tinyows

The simplicity is a little bit too much, when it comes to serve multiple WFS-T on the same server. There is only one configuration file, but we want a configuration for each service. There are solutions for that, but I never saw a documentation of the most elegant solution we found. It uses Apache rewrite capabilities to set the TINYOWS_CONFIG_FILE environment variable according to the called URL:

# URL rewriting
RewriteEngine On

# Forbid direct access
RewriteRule ^/cgi-bin/.*$ - [F]

# Rewrite /xxx to /cgi-bin/tinyows with TINYOWS_CONFIG_FILE=/etc/tinyows/xxx.xml
RewriteRule ^/(.+)$ /cgi-bin/tinyows [QSA,PT,L,E=TINYOWS_CONFIG_FILE:/etc/tinyows/$1.xml]

This configuration included in a virtual host declaration (wfs.example.com) serves your WFS-T on wfs.example.com/servicename.

The state of QGIS Globe

2012-12-15T20:36:00Z

The Region of Umbria, Italy, sponsored 4 days of work to update QGIS Globe for current QGIS versions. Most of the functionality is working again and the globe is now compatible with osgEarth 1.0 up to 1.3. The bad news is, that the globe plugin is not working on Windows with OSGeo4W. It seems that one of the OSGeo4W libraries (GDAL?) is compiled with an incompatible MS compiler version. Christmas holidays are coming…

At least it gives Linux users the possibility to play with the globe using the current development version and do exciting stuff like Oslandia does:

Imagine someone would sponsor four weeks of QGIS Globe work!

New configuration options in QGIS server

2012-10-30T15:54:00Z

In QGIS server, it is now possible to selectively exclude layers from WMS publication. These layers will be available only on the desktop and hidden from WMS clients. Similarly, print layouts can be excluded from WMS publication. Of course, these settings are conveniently accessible from the project properties dialog of QGIS (but you need to have a nightly build or a recent compile):

Additionally, attributes per layer can be excluded from WMS or WFS publication in the vector properties dialog:

There is also a new request type called ‘GetProjectSettings’. The output of this request is similar to the GetCapabilities output, but with more details and more specific to QGIS:

Initial visibility of layers
Information about vector attributes and their edit types
Information about layer order and drawing order
List of layers published in WFS

These new features have been developed in collaboration and with funding from the city of Uster. More details are available on the QGIS server / webclient wiki page

Creating png8 images with QGIS server

2012-10-02T07:21:00Z

For providing maps via WMS over the internet, it is important to generate image files with a small size. Because normally, most of the perceived WMS delay comes from transfering large images files over the internet (and not from map rendering itself). Therefore, QGIS server supports the conversion of png24 and png32 images into png8, therefore generating a file with only 1/3 resp. 1/4 of the original size (but with lower quality). However, until recently, QGIS server was using the default algorithm from the Qt library for conversion to png8, resulting in very ugly png8 images if used with a transparent background and sometimes with shifted colors. Therefore, I decided to implement a better conversion algorithm: the median cut algorithm, which was first described by Heckbert in 1982 ( Paul S. Heckbert, Color Image Quantization for Frame Buffer Display. ACM SIGGRAPH ‘82 Proceedings). This algorithm creates color boxes in 4-dimensional colour space and subdivides at the mean of the largest dimension. It stops if the number of boxes equals the requested number of colors (256 in the case of png8 conversion). First tests show the quality of the converted images are quite good for vector maps. So a performant configuration for a webmap means probably to fetch background rasters as jpg and to overlay vectors as png8 with transparent background.

Let’s see with an example what the conversion from png24 to png8 means in terms of image quality. The first file is a png24 image, 590 KB size:

And this one is the conversion to png8, only 190 KB size.

To test the png8 conversion, you need to have the latest QGIS version from git (or a nightly build tomorrow). Then simply replace the FORMAT paramter in the url with ‘&FORMAT=image/png; mode=8bit’.

Howto shrink a remote root ext3 filesystem on Debian wheezy

2012-09-11T17:49:00Z

This howto describes how to resize a root ext3 filesystem on a remote Debian wheezy server.

This howto is not an original work but only an update of an older howto by Stefan @ https://thunked.org/. This version is specifically adapted to a server running Debian wheezy.

DISCLAIMER:

THERE IS A DECENT CHANCE THAT IF YOU FUCK THIS UP YOUR
REMOTE SYSTEM SIMPLY WONT BOOT AT ALL.  I URGE YOU TO TEST
THIS LOCALLY BEFORE USING THIS METHOD ON A PRODUCTION
SYSTEM. ESPECIALLY IF YOUR SYSTEM IS NOT DEBIAN WHEEZY,
SINCE THAT'S THE ONLY ONE I HAVE TESTED.

THE QUICK WAY:

If you don't want to read the whole thing you can only
execute the commands I run and probably skip the
explanations.

I’ve only done this on Debian Wheezy. If you’re using another distro the initrd layout and init scripts may be a bit different. However, I suspect it looks very similar on almost every distro out there. On Debian my root partition is an ext3 partition.

The general idea is pretty simple: you can’t shrink a mounted partition and it’s impossible to unmount or replace your root partition in a live system, so we have to resize the partition before it is mounted. What we’ll do to accomplish this is change the initrd image to make the init scripts resize the root partition before mounting it. This is by far the most flexible and easy method to resize your root partition I could think of. Most suggestions I found on google required you to create separate OS on a new root partition and boot into that, but I did not have any space to create a new root partition on my remote machine.

Unpacking the initrd image is fairly straight forward:

$ mkdir ~/initrd; cd ~/initrd
$ gunzip -c /boot/initrd.img-3.2.0-3-amd64 | cpio -i --make-directories
62631 blocks
$ ls -l
total 40
drwxr-xr-x 2 root root 4096 Sep 11 20:23 bin
drwxr-xr-x 3 root root 4096 Sep 11 20:23 conf
drwxr-xr-x 6 root root 4096 Sep 11 20:23 etc
-rwxr-xr-x 1 root root 6797 Sep 11 20:23 init
drwxr-xr-x 7 root root 4096 Sep 11 20:23 lib
drwxr-xr-x 2 root root 4096 Sep 11 20:23 lib64
drwxr-xr-x 2 root root 4096 Sep 11 20:23 run
drwxr-xr-x 2 root root 4096 Sep 11 20:23 sbin
drwxr-xr-x 6 root root 4096 Sep 11 20:23 scripts

First, we have to copy all the programs we need to resize our partition onto the initial ram disk. For my ext3 file system I need e2fsck and resize2fs. The programs are depending on a few libraries, so you’ll need to copy those to the new initrd image too. Libraries can also depend on other libraries, make sure you recursively check dependencies until you don’t have any missing dependencies anymore.

$ ldd /sbin/e2fsck
    linux-vdso.so.1 =>  (0x00007fff3594c000)
    libext2fs.so.2 => /lib/x86_64-linux-gnu/libext2fs.so.2 (0x00007f7cdddd5000)
    libcom_err.so.2 => /lib/x86_64-linux-gnu/libcom_err.so.2 (0x00007f7cddbd1000)
    libblkid.so.1 => /lib/x86_64-linux-gnu/libblkid.so.1 (0x00007f7cdd9a9000)
    libuuid.so.1 => /lib/x86_64-linux-gnu/libuuid.so.1 (0x00007f7cdd7a4000)
    libe2p.so.2 => /lib/x86_64-linux-gnu/libe2p.so.2 (0x00007f7cdd59c000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7cdd214000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7cdcff8000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f7cde01e000)
$ ldd /sbin/resize2fs
    linux-vdso.so.1 =>  (0x00007fffa216a000)
    libe2p.so.2 => /lib/x86_64-linux-gnu/libe2p.so.2 (0x00007fa01f7a2000)
    libext2fs.so.2 => /lib/x86_64-linux-gnu/libext2fs.so.2 (0x00007fa01f55f000)
    libcom_err.so.2 => /lib/x86_64-linux-gnu/libcom_err.so.2 (0x00007fa01f35a000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa01efd3000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa01edb7000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fa01f9b0000)

We only copy the libraries that are not yet present in the initramfs. Fortunately in our case there are no recursive dependencies of those libraries.

$ for i in libext2fs.so.2.4 libcom_err.so.2.1 libe2p.so.2.3; do \
     cp -i /lib/x86_64-linux-gnu/$i lib/x86_64-linux-gnu/; \
  done
$ cd lib/x86_64-linux-gnu/
$ ln -s libcom_err.so.2.1 libcom_err.so.2
$ ln -s libext2fs.so.2.4 libext2fs.so.2
$ ln -s libe2p.so.2.3 libe2p.so.2
$ cd ~/initrd/

$ cp /sbin/e2fsck ~/initrd/bin/
$ cp /sbin/resize2fs ~/initrd/bin/

Next, we need to edit the init script. Debian uses busybox in its initrd image so the init script will be interpreted by a bourne shell. If you look through the init script file you’ll find the moment where the script mounts the root file system:

$ cat scripts/local
...
    # FIXME This has no error checking
    # Mount root
    if [ "${FSTYPE}" != "unknown" ]; then
            mount ${roflag} -t ${FSTYPE} ${ROOTFLAGS} ${ROOT} ${rootmnt}
    else
            mount ${roflag} ${ROOTFLAGS} ${ROOT} ${rootmnt}
    fi
...

Simply add in the commands to resize the file system right before the the file system is mounted. Resize2fs in Debian does not want to resize the file system before it is forcefully checked. It may be wise to add the -p or -y flag to e2fsck. -y will answer yes to all questions, this could prevent a hung system but may cause more damage to your files or filesystem. The -p flag will only automatically answer yes to safe operations. resize2fs takes two parameters, the first is the block device that has the ext2 or ext3 file system and the second is the new size you want to give it. By default the size is in blocks, but you can append a unit to change that. ‘K’ for kilobytes, ‘M’ for megabytes, ‘G’ for gigabytes and ‘T’ for terabytes. If you don’t specify a size, it will enlarge the file system to the total size of the partition or logical volume. After adding the commands the init script will look something like this:

    #RESIZEROOTFS MODIFIED!!! DONT RUN MORE THAN ONCE
    _log_msg "Starting e2fsck"
    /bin/e2fsck -p -f -C 0 /dev/sda4 || true
    _log_msg "Starting resize2fs"
    /bin/resize2fs /dev/sda4 100G || true

    # FIXME This has no error checking
    # Mount root
    if [ "${FSTYPE}" != "unknown" ]; then
            mount ${roflag} -t ${FSTYPE} ${ROOTFLAGS} ${ROOT} ${rootmnt}
    else
            mount ${roflag} ${ROOTFLAGS} ${ROOT} ${rootmnt}
    fi

If you have access to the system’s console, you might want to add a “-C 0” to e2fsck’s parameters. That will show you the progress of the fscheck.

There’s one last thing we have to do before re-packing the initrd image. e2fsck and resize2fs will fail if there is no /etc/mtab file available so we’ll have to make sure /etc/mtab exists.

$ touch ~/initrd/etc/mtab
$ cd ~/initrd/
$ find ./ | cpio -H newc -o > /tmp/initrd.cpio
64097 blocks
$ gzip -c /tmp/initrd.cpio > /boot/initrd-resize.img

And lastly, we need to add a new default boot option in grub. In Debian grub’s configuration file is constructed from various bits under /etc/grub.d. The resulting total configuration file is put under /boot/grub/grub.cfg. Open up the grub.cfg file in your favorite text editor and look for the default entry. It’s usually the first one, but may vary. Add a copy of the original entry to /etc/grub.d/40_custom and change the initrd image to the one we just created.

$ cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry 'resize' --class debian --class gnu-linux --class gnu --class os {
        insmod gzio
        insmod part_gpt
        insmod ext2
        set root='(hd0,gpt1)'
        search --no-floppy --fs-uuid --set=root 0aa8bc27-17e3-4ae2-a9cf-497ab444970b
        echo    'Loading Linux 3.2.0-3-amd64 ...'
        linux   /vmlinuz-3.2.0-3-amd64 root=UUID=660f79dc-c152-4e15-ad61-7075b42de609 ro  quiet
        echo    'Loading initial ramdisk ...'
        initrd  /initrd-resize.img
}

Now make sure that it’s this entry that will be booted into by default. Set GRUB_DEFAULT in /etc/default/grub to the name of the entry you’ve just created:

$ cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

#GRUB_DEFAULT=0
GRUB_DEFAULT="resize"
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""
...

Finally, you can reboot the system. When it comes back online (if it comes back grin) your file system will be resized. Be aware that e2fsck and resizefs take a long time on big disks. On my system the two took 2 hours for a 1.5T filesystem. Thus don’t prematurely reboot your system if it doesn’t come up again quickly.

Don’t forget to remove the new grub entry, so your file system doesn’t get resized every time you boot.

Microsoft blocking emails to you

2012-06-20T14:36:00Z

It’s now a month, that we can’t send email to any Microsoft owned mail domain - for example to hotmail.com or to live.com.

Microsoft is blocking us. We can actually communicate with their first level support staff responsible for the mail servers, however they will neither tell us why we are blocked, nor what we have to do to get unblocked, nor when the block would get lifted.

They propose a whole laundry list of things for us to do - registering with them and constantly maintaining and monitoring our status at some service of theirs. We’d certainly spend half a week to implement those measures and then spend ongoing time to maintain them. But none of that is guaranteed to be of any help.

So if you need to email us then please do not use any of your hotmail accounts for the communication - we unfortunately can not reach you any more.

And it seems we’re not the only ones receiving that treatment by Microsoft.

Generating state machines with Dia

2012-06-07T15:10:00Z

Dia is a nice cross platform application for diagram drawing. It can be scripted via Python, which opens the possibility to generate code from Dia diagrams.

Below we’ll create a python plugin that generates C code from UML state machine diagrams. Doing the same for other languages should be trivial.

The first thing you need is Unai Estébanez Sevilla’s nice finite state machine code generator. The version that we are using here has been abstracted in order to be able to produce code in various languages.

This python plugin implements an exporter to C code. To use it, you need to put it, along with the base exporter into your local plugins directory under ~/.dia/python.

Let’s have a quick look at the code.

First we import the dia python module and the exporter base functionality:

import dia
import uml_stm_export

Then we create our C exporter class that inherits from the generic exporter:

class CDiagramRenderer(uml_stm_export.SimpleSTM):

Next we define how the beginning of our generated code file should look like. That could include general infrastructure independent of the state machine diagram at hand. In our case, we want to encapsulate the generated state machine code within a function:

CODE_PREAMBLE="void config_stm(STM_t* stm) {"

We also define the postamble to close the function. After that come generic functions that implement the class constructor init(self) and functions responsible for calling the dia object parser begin_render(self,data,filename).

Now we define our output generator end_render(self). We first traverse dia’s objects in order to find the state machine’s initial state:

for transition in self.transitions:
   if(transition.source == "INITIAL_STATE"):

The initial state state gets a special treatment: we have a special function call generated for it:

f.write("    add_initial_state( stm, %s, %s );\n" %
    (initial_state.name, initial_state.doaction))

Next we traverse all states and output code that will create them, along with functions to be called within that state to decide on where to transition next:

for key in self.states.keys():
    f.write("    add_state( stm, %s, %s );\n"
        % (state.name, state.doaction))

And finally we output all the transitions between states:

for transition in self.transitions:
    f.write("    add_transition( stm, %s, %s, %s );\n" %
        (transition.source, transition.trigger, transition.target))

and that’s nearly it. At the end of our generator we make sure to register it with dia:

dia.register_export("State Machine Cstma Dump", "c", CDiagramRenderer())

Done! Simple, isn’t it?

Finally please permit me to thank all the people that created such a powerful tool free for us to use:

Unai Estébanez Sevilla for the original STM generator
Steffen Macke and Hans Breuer, Dia’s current busy maintaners
Alexander Larsson, Dia’s original author
all the other contributors to Dia and free software
Panter for inviting me to their fabulous work week in Greece where most of the hacking on the generator was done and Combitool who supported this work by needing a state machine generator in their current project.

PS: Unai’s original text generator is now also “just” a “simple” addon

Automatically restarting services after upgrades on Debian and Ubuntu

2012-06-07T14:38:00Z

There are various tools to automatically keep a Debian/Ubuntu system security wise up to date, among others the unattended-upgrades package.

Also, there’s the checkrestart script from the debian-goodies package, that scans all the open files on a system and tries to determine to what service they belong and how that service might be restarted.

The last piece that’d tie all those scripts together and would automatically restart all services that are using stale libraries or files was missing.

With the help of Michal Fiala there however is now the restart-services script, that does just that.

The script has not seen much real world usage and as such should be regarded as experimental (f.ex. by restarting /etc/init.d/screen it will as of the time of writing terminate existing screen sessions).

The script currently lives on Github. If you encounter any problem with the script then we’ll very much wellcome a patch that fixes it…

Tomáš Pospíšek

Update 18.6.2012: The most recent checkrestart (from debian-goodies 0.61) now excludes screen from beeing listed among the services to be restarted.
