CloudFlare suffered a massive security issue affecting all of its customers, including Rosetta Code. All passwords not changed since February 19th 2017 have been expired, and session cookie longevity will be reduced until late March.--Michael Mol (talk) 05:15, 25 February 2017 (UTC)

Rosetta Code/List authors of task descriptions

From Rosetta Code
Rosetta Code/List authors of task descriptions is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
In this task, the goal is to compile an authorship list for task descriptions. A pseudocode example (in imperative style) that should accomplish this is as follows:
for each task page
grab page source, discard everything after the first ==section==.
Cache as $previous. Note $author.
for each revision
grab page source, discard everything after first ==section==.
Cache as $previous2. Note $author2
compare $previous2 to $previous. If different, record $author to $list.
replace $previous with $previous2
replace $author with $author2

The following resources for HTTP interface information for MediaWiki may prove to be useful:

Conversely, some languages have libraries which abstract these interfaces into language-native idioms. Use of these abstractions is perfectly fine.
