wikiteam3

Dynamic JSON Badge PyPI version

Countless MediaWikis are still waiting to be archived.

wikiteam3 is a fork of mediawiki-scraper.

## Why we fork mediawiki-scraper Originally, mediawiki-scraper was named wikiteam3, but wikiteam upstream (py2 version) suggested that the name should be changed to avoid confusion with the original wikiteam. Half a year later, we didn't see any py3 porting progress in the original wikiteam, and mediawiki-scraper lacks "code" reviewers. So, we decided to break that suggestion, fork and named it back to wikiteam3, put the code here, and release it to pypi wildly. Everything still under GPLv3 license.

For webmaster

We archive every MediaWiki site yearly and upload to the Internet Archive. We crawl sites with 1.5s crawl-delay by default, and we respect Retry-After header. If you don’t want your wiki to be archived, add the following to your <domain>/robots.txt:

User-agent: wikiteam3
Disallow: /

Installation/Upgrade

pip install wikiteam3 --upgrade

[!NOTE] For public MediaWiki, you don't need to install wikiteam3 locally. You can send an archive request (include the reason for the archive request, e.g. wiki is about to shutdown, need a wikidump to migrate to another wikifarm, etc.) to the wikiteam IRC channel. An online member will run a wikibot job for your request.

Even more, we also accept DokuWiki and PukiWiki archive requests.

Downloading a wiki with complete XML history and images

wikiteam3dumpgenerator http://wiki.domain.org --xml --images

[!WARNING]

NTFS/Windows users please note: When using --images, because NTFS does not allow characters such as :*?"<>| in filenames, some files may not be downloaded, please pay attention to the XXXXX could not be created by OS error in your errors.log. We will not make special treatment for NTFS/EncFS "path too long/illegal filename", highly recommend you to use ext4/xfs/btrfs, etc.

- Introducing the "illegal filename rename" mechanism will bring complexity. WikiTeam(python2) had this before, but it caused more problems, so it was removed in WikiTeam3. - It will cause confusion to the final user of wikidump (usually the Wiki site administrator). - NTFS is not suitable for large-scale image dump with millions of files in a single directory.(Windows background service will occasionally scan the whole disk, we think there should be no users using WIN/NTFS to do large-scale MediaWiki archive) - Using other file systems can solve all problems.

Manually specifying api.php and/or index.php

If the script can't find itself the api.php and/or index.php paths, then you can provide them:

wikiteam3dumpgenerator --api http://wiki.domain.org/w/api.php --xml --images
wikiteam3dumpgenerator --api http://wiki.domain.org/w/api.php --index http://wiki.domain.org/w/index.php \
    --xml --images

If you only want the XML histories, just use --xml. For only the images, just --images. For only the current version of every page, --xml --curonly.

Resuming an incomplete dump

```bash wikiteam3dumpgenerator \ --api http://wiki.domain.org/w/api.php --xml --images --resume --path /path/to/incomplete-dump ``` In the above example, `--path` is only necessary if the download path (wikidump dir) is not the default. >[!NOTE] > > en: When resuming an incomplete dump, the configuration in `config.json` will override the CLI parameters. (But not all CLI parameters will be ignored, check `config.json` for details) `wikiteam3dumpgenerator` will also ask you if you want to resume if it finds an incomplete dump in the path where it is downloading.

Using wikiteam3uploader

```bash usage: Upload wikidump to the Internet Archive. [-h] [-kf KEYS_FILE] [-c {opensource,test_collection,wikiteam}] [--dry-run] [-u] [--bin-zstd BIN_ZSTD] [--zstd-level {17,18,19,20,21,22}] [--rezstd] [--rezstd-endpoint URL] [--bin-7z BIN_7Z] [--parallel] wikidump_dir positional arguments: wikidump_dir options: -h, --help show this help message and exit -kf, --keys_file KEYS_FILE Path to the IA S3 keys file. (first line: access key, second line: secret key) [default: ~/.wikiteam3_ia_keys.txt] -c, --collection {opensource,test_collection,wikiteam} --dry-run Dry run, do not upload anything. -u, --update Update existing item. [!! not implemented yet !!] --bin-zstd BIN_ZSTD Path to zstd binary. [default: zstd] --zstd-level {17,18,19,20,21,22} Zstd compression level. [default: 17] If you have a lot of RAM, recommend to use max level (22). --rezstd [server-side recompression] Upload pre-compressed zstd files to rezstd server for recompression with best settings (which may eat 10GB+ RAM), then download back. (This feature saves your lowend machine, lol) --rezstd-endpoint URL Rezstd server endpoint. [default: http://pool- rezstd.saveweb.org/rezstd/] (source code: https://github.com/yzqzss/rezstd) --bin-7z BIN_7Z Path to 7z binary. [default: 7z] --parallel Parallelize compression tasks ```

Requirements

[!NOTE]

Please make sure you have the following requirements before using wikiteam3uploader, and you don't need to install them if you don't wanna upload the dump to IA.

Uploader usage

[!NOTE]

Read wikiteam3uploader --help and do not forget ~/.wikiteam3_ia_keys.txt before using wikiteam3uploader.

wikiteam3uploader {YOUR_WIKI_DUMP_PATH}

Checking dump integrity

TODO: xml2titles.py

If you want to check the XML dump integrity, type this into your command line to count title, page and revision XML tags:

grep -E '<title(.*?)>' *.xml -c; grep -E '<page(.*?)>' *.xml -c; grep \
    "</page>" *.xml -c;grep -E '<revision(.*?)>' *.xml -c;grep "</revision>" *.xml -c

You should see something similar to this (not the actual numbers) - the first three numbers should be the same and the last two should be the same as each other:

580
580
580
5677
5677

If your first three numbers or your last two numbers are different, then, your XML dump is corrupt (it contains one or more unfinished </page> or </revision>). This is not common in small wikis, but large or very large wikis may fail at this due to truncated XML pages while exporting and merging. The solution is to remove the XML dump and re-download, a bit boring, and it can fail again.

[!IMPORTANT]

In the article name, spaces and underscores are treated as equivalent and each is converted to the other in the appropriate context (underscore in URL and database keys, spaces in plain text). https://www.mediawiki.org/wiki/Manual:Title.php#Article_name

[!NOTE]

WikiTeam3 uses zstd to compress .xml and .txt files, and 7z to pack images (media files).
zstd is a very fast stream compression algorithm, you can use zstd -d to decompress .zst file/steam.
