container-images's Introduction

Kiwix

Kiwix is an offline reader for Web content. It's especially thought to make Wikipedia available offline. This is done by reading the content of the project stored in a file format ZIM, a high compressed open format with additional meta-data.

COMPILATION INSTRUCTIONS

Take care, the paragraphs are about the target platforms. If you want to build Kiwix for Android on a GNU/Linux system, you should follow the instructions of the "Android" paragraph.

GNU/Linux

Install pre-requisties in your distro, eg, in Debian based:

sudo apt-get install zip pkg-config aptitude
sudo apt-get install libmagic-dev
sudo aptitude install libtool automake

Static (Probably what you need to do if you don't know)

Kiwix uses shared libraries only. A static build of Kiwix is a build which packages the dependencies. Command line tools (indexer, server, etc) are compiled statically.

Run automake

./autogen.sh

Run autoconf

./configure --enable-compileall --enable-staticbins --disable-android;

Download all dependencies

cd src/dependencies;
make;
cd ../..;

Reconfigure with dependencies (Gecko version)

./configure --enable-compileall --enable-staticbins --disable-android;

Compile

make;

Creates tarbal suitable for distribution (no deps)

make diststatic
  • If you want to be able to run directly from your dev repository copy the "xulrunner" directory in the distributation tarball to the "kiwix" sub-directory of your developement tree.

  • Don't try to install with "make install", if you want to have kiwix install on your system just copy the directory in a /usr/local/bin directory.

Dynamic

GNU/Linux build uses shared libraries by default. You will need the following dependencies (also -dev packages) to compile Kiwix for Linux (this list can vary a little bit depending of the GNU/Linux distribution):

  • g++
  • gcc
  • autoconf
  • automake
  • libtool
  • pkg-config
  • liblzma
  • libicu
  • libmicrohttpd
  • zlib
  • libcrypto++
  • cmake
  • wget
  • aria2
  • libuuid
  • libssl
  • libzim
  • libpugixml
  • libctpp2
  • xulrunner

Debian is the only distribution providing natively all these packages. Ubuntu provides most of them, excluding xulrunner and zimlib. You will have to download and install them separatly or run configure --with-static-dep=SELF. Then run the following commands:

Run automake

./autogen.sh;

Configure the compilation check --help for options. Most dependencies accept --with-dep=XX and with-static-dep=XX.a. Static version of libraries are used for building static binaries (server, indexer, etc) Use --with-dep=SELF or --with-static-dep=SELF to trigger fetch and build for the dependency.

./configure;

Compile

make;

Optionaly install on the filesystem

sudo make install;

Mac OSX Universal

WARNING: To build the Mac OS version you will have to install proprietary software which are free of charge. You will also need to build on an Apple Mac computer.

Configure Macports

Install the following tools and libraries

sudo port install autogen +universal pkgconfig +universal wget +universal gmake +universal coreutils +universal libidl +universal autoconf213 +universal icu +universal;

NOTE: the following commands seem to work better on OS X Yosemite, apparently 'universal' is less relevant and various packages are no longer available as universal options.

sudo port  install autogen pkgconfig  wget  gmake  coreutils  libidl  autoconf213  icu;
sudo port -v install aclocal automake libtool autoconf cmake imagemagick
./autogen.sh alt && ./configure --enable-compileall;
cd src/dependencies && make;
make clean;
./autogen.sh alt && ./configure --enable-compileall --enable-compileall --disable-dependency-tracking --with-target-arch=i386;
make;
make distmac;
make clean;
./autogen.sh alt && ./configure --enable-compileall --enable-compileall --disable-dependency-tracking --with-target-arch=x86_64;
make;
make distmac;
make universal;
Debugging tips:
  • components file type can be either Mach-O dynamically linked shared library or Mach-O bundle but above instructions will create dynamic libraries.
  • Shared Object (.so files on Linux) have .dylib extension on OSX.
  • use dtruss to inspect program execution like strace.
  • dyldinfo -lazy_bind | dyldinfo -bind components/zimAccessor.dylib |grep zim
  • nm -gm components/zimAccessor.dylib | nm -u | nm -g
  • otool -L libzim.dylib
  • install_name_tool -change @executable_path/../libicuuc.dylib libicuuc.dylib kiwix-serve
  • lldb

container-images's Issues

download.kiwix.org alwys computing hash from files with "mb"

As we are almost not adding files, this is wrong. I suspect that (part of) the problem comes from the the fact that the hash are not store in the DB but in /usr/share/mirrorbrain which is not part of any volume. This should be at least fixed.

`manageContentRepository.pl` is called in none of the docker images

It should run one time a day, here is how the cron looks like on the old server:

30   2   *   *   *    cd /var/www/kiwix/tools/tools/scripts ; ./manageContentRepository.pl --wikiPassword=42 --writeWiki --writeHtaccess --writeLibrary --deleteOutdatedFiles

This should be introduced in the library Dockerfile.

docker rsync container keeps restarting

`robots.txt` has not being migrated in library image and more

In the original Nginx vhost:

  location /robots.txt {
    alias /var/www/library.kiwix.org/robots.txt;
  }

with robots.txt is

User-agent: *
Crawl-delay: 3

On the top it is also really important to threshold the number of request to library.kiwix.org. Our old Nginx configuration had:

limit_req_zone $binary_remote_addr zone=limit:10m rate=3r/s;

This should be migrated too

[URGENT] Download server with a load > 3

Something goes wrong and I strongly suspect something is wrong around Matomo import_logs.py... or something is wrong with kiwix-serve which is really high on the IO too, maybe a consequence that the library.kiwix.org throttling does not work well?

We need a zimquarantine-docker

ZIM files which are uploaded to download.kiwix.org should be checked before being made fully available to download. We have a tool called zimcheck (part of the zim-tools) aimed to do that checks. This task is about making a Docker container able to use that tool.

This Docker image should:

  • Have an input directory (volume)
  • Have an output directory (volume)
  • Monitor the input directory for ZIM files, check them if zim-check and if OK them move them to output directory (keeping the subdirectory hierarchy).
  • How the system should behave if an error occurs is a bit unclear so far to me: ideally it should inform the zimfarm if possible (transmit the log), but would prefer to keep that Docker image AFAP independent of the zimfarm. Maybe both requirements are mutually exclusive!?!

Remarks:

  • We should check that the move operation (if successful is immediate), otherwise the rest of the toolchain might have problem with incomplete ZIM files

This task depends on openzim/zim-tools#26

Weaknesses in library-docker

library.kiwix.org.xml is not generated. This is how it is on the old serveur:

/var/www/kiwix/tools/tools/scripts/manageLibraryKiwixOrg.pl --source=/var/www/download.kiwix.org/library/library_zim.xml > library.kiwix.org.xml

This should be synced one time a day automatically

On the top of that, the kiwix-serve should be run in a while true loop, to avoid the whole service to dies if there is a bug in kiwix-serve causing a crash. Currently we run:

 while [ 42 ] ; do kiwix-serve --port=4242 --library --interface=lo --threads=16 --verbose library.kiwix.org.xml ; sleep 1 ; done

Library kiwix-serve is not restarted one time a day

I see in the process that it runs for more than 24h. One time a day, the library.kiwix.org.xml should be newly generated and kiwix-serve restarted to take in account the new library.kiwix.org.xml file.

Prepare letsencrypt and reverse-proxy to welcome stats.kiwix.org

Unfortunately we can not really host that in the cloud, would be to expensive. So we will have to put it on that box two, that should be able to work without problem. I will create the docker-compose and take care of the migration, but we should also update the other dockers.

HTTP should be a redirect to HTTPS

Update mirrors.hml

It seems there is no code migrated to docker to update https://mirror.download.kiwix.org/mirrors.html.

This code is in the cron on the old server and looks like following:

 mb mirrorlist -f xhtml | grep -v "href=\"\"" > /var/www/download.kiwix.org/mirrors.html

It should be put IMO in the mirrorbrain-update container.

Are the mwoffliner scripts really the scripts used to generate Kiwix files?

Underlying goal: When debugging, I sometimes want to determine the real commands used for a failing build.

I ask because mwmatrixoffliner has a miscapitalized parameter --mwURL, while mwoffliner and these scripts use --mwUrl.
I'm about to change mwmatrixoffliner to match.

But as I understand it, these commands should not even work with mwmatrixoffliner due to the difference. It doesn't work on my command line when I try to use --mwUrl as these scripts do.

Are these the real scripts used?

Kiwix & openZIM wikis are very slow

Need more RAM :

$ sloppy stats openzim 
CONTAINER 		 CPU % 	 MEM / LIMIT 		 MEM % 	 NET I/O Extern 	 NET I/O Intern
openzim/wiki-ad4ada 	 0.4% 	 960 MiB / 960 MiB 	 100.0%  410 B / 2.39 KiB 	 10.9 B / 0 B

[URGENT] library.kiwix.org SSL certificate wrong

$ curl https://library.kiwix.org/
curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

And all of this should work automatically, so I don't understand why we have this kind of problem.

zim directory in zim directory

$ pwd
/data/download/zim
$ ls -lad zim 
lrwxrwxrwx 1 root root 32 Dec  2 16:37 zim -> /var/www/download.kiwix.org/zim/

@florentk I suspect you have added it, but of course this is wrong and I have removed it. Any reason why we have this link here?

Can we give the mwoffliner scripts more descriptive names?

While debugging, I sometimes try to find the command for a particular build. For example, to determine whether a particular Kiwix file is built in mobile mode or not.

The existing script names give me no clue which file will have a particular build. I just have to search them all.

In particular, the endings _dump, _shm, and _zim don't appear to be different as far as I can tell. The files just seem to have different wikis and languages. Do those suffixes mean anything?
And of course 1, 2, 3, 4, 5 don't give any insight.

[URGENT] Cronjobs run should be protected to avoid overlapping

To avoid cronjobs scripts to run in parallel, they should be "protected" by the usage of flock. All of this is properly configured on the current download server but has been removed in the Docker images/containers.

The overall server stability is put currently in danger because of this bug.

All visitors have a same IP on Sloppy

When I receive mail confirmation, the IP adresse is always the same : 192.168.18.27. Then the limite of 99 account creation is reacheable in 24 hours, and nobody can create a new account. Maybe a bot creates accounts.

Create a super-seeder docker image/container

Looks like still not all BitTorrent clients can deal properly with our Web seeds. Having a complete and always running super-seeder would help to solve that problem. We could run it on a mirror (files already there). Additionally this Docker image might be interesting to a few Kiwix supporters who have that way a solution to support the project by easily sharing a bit of there bandwidth.

Using rsync, see https://download.kiwix.org/README, and rtorrent, that should not be too complicated.

MWOffliner for Ted.com

I would love to create a new Ted.com zim file, that latest one is from 2016-06. I read the Wiki (http://wiki.kiwix.org/wiki/TED) but I couldn't find any source code.

Is anyone aware of some code that works (or used to work). I may update/fix it so we have an uptodate archive.

Library is regularly down

The monitoring of the https service tells me:
The monitor Library (https://library.kiwix.org) is currently DOWN (HTTP 502 - Bad Gateway).

I had a brief look to the error log and it seems the limit is not configured properly.

Nighlies should be removed periodicaly

Here are the cron entries on the old download server:

0 0 * * * find /var/www/download.kiwix.org/nightly/ -mindepth 1 -maxdepth 1 -type d -mtime +30 -exec rm -rf {} \;
0 0 * * * find /var/www/download.openzim.org/nightly/ -mindepth 1 -maxdepth 1 -type d -mtime +30 -exec rm -rf {} \;
