Opasnet update 2017

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

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->mysqli
  - fixed: wfMsg->wfMessage
- <rcode> tag
  - Detected by parser hooks
  - RToolsParser class
    - fixed: wfMsg->wfMessage
    - fixed: class instead of global functions
      - create class instance in parser given by hook in order to retain variable values
- rtools_client
  - handles connections and job submissions etc. to server
  - xml-rpc library
    - communicates with rtools_server API
- javascripts
  - UI?
  - ajax?
- livecode?
- 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
