This page contains notes produced while updating Opasnet server systems during the summer of 2017.

RTools server

CentOS 6.4: full support ended, but still get maintenance updates.

Key software, upgrade paths and related issues:

• apache 2.2.15 -> 2.2.32 or 2.4.25
  • newer branch not particularly important
• PHP 5.3.3 -> 5.6.x or 7.1.x
  • incompatibilities in mysql functions
    • "mysql" -> "mysqli" (5.5)
  • should upgrade to latest version
• MySQL 5.1 -> 5.7
• mongoDB 2.4 -> 3.2
  • should be relatively easy as we are not using sharding etc.
• rtools_server PHP application
  • starts on test server after minor changes
  • further testing needed
• opasnet_base2

Opasnet-wiki server

CentOS 6.5: full support ended, but still get maintenance updates.

Key software, upgrade paths and related issues:

• apache 2.2.15 -> 2.2.32 or 2.4.25
• PHP 5.4.28 -> 5.6.x or 7.1.x
  • 5.5.9+ required by currently supported mediawiki releases
  • latest php also supported
  • incompatibilities likely to occur in 5.4->5.5, hence might as well upgrade to latest
• MySQL 5.5.37 -> 5.5.56 or 5.7.x
• MediaWiki 1.20.0 -> 1.27 (LTS) or 1.28.2 (latest)
  • need to check supported extensions
  • MyExtension.php no longer supported, need extension.json for registering extensions
  • Composer might be useful for managing PHP dependencies

RTools MediaWiki extension

• RTools special page class (now named SpecialRtools)
  • Creates instance of rtools_client
  • separate config file, which is included by SpecialRTools instead of rtools_client for some reason
  • fixed: "mysql" to "mysqli"
  • fixed: "wfMsg" to "wfMessage->text()"
• <rcode> tag
  • Detected by parser hooks
  • RToolsParser class
    • fixed: "wfMsg" to "wfMessage->text()"
    • fixed: class instead of global functions
      • create class instance in parser given by hook in order to retain variable values
    • fixed: added "wgOut->addModules( 'ext.RTools.parser' );" which enables the on-page UI
    • fixed: changed efRCodeMBInArray to a static function and changed reference in templates/inputs/checkbox.php
• rtools_client
  • handles connections and job submissions etc. to server
  • xml-rpc library
    • communicates with rtools_server API
• javascripts
  • script.aculo.us + prototype
    • UI
    • ajax
    • old versions, probably still acceptable
  • loaded by mediawiki resource loader
    • now set up in extension.json
• wiki database
  • rtools_inputs
    • added schema update hook to create the necessary table if missing
• Current issues:
  • Show code button does not work
  • Run page throws: Didn't receive 200 OK from remote server. (HTTP/1.0 500 Internal Server Error), which is a xml-rpc related error
  • Runs and shows outputs (oprint and cat), but code is not visible, embed also does not work
  • Input forms are slightly broken: conditional categories do not work, checkboxes crash the whole page
  • Rtools page does not update, shows error until refreshed once the run is over. Error on page: "jQuery is not defined", but it is loaded by mediawiki by default. Caused by some linking problem between the special page and mediawiki.
    • SpecialRTools-class problem with include of "template/index.php" in method "output" not scoping as expected. Including javascript dependencies separately resolves the first issue, but results in "mw not defined" indicating no access to mediawiki.
    • Special page includes javascript for both parser and special page, which does not happen on the current server. It is loaded as part of parser initialization on every page.
