Editing TEHCC Wiki:Maintenance

{{#arraydefine:phpcommand|php}}<!-- Load with any special directory specifying required to access desired version of php -->
{{#arraydefine:mwInstallVersion|mediawiki-1.38.7}}<!-- Use to update examples to be useful -->
'''Note!''' Current host doesn't have issue with calling old versions of php. So, when instructions call for <kbd>php</kbd> you can just use <kbd>{{#arrayprint:phpcommand}}</kbd>. The variable code left in, in the event that ever changes again.

==Installed Extensions Reference==
The following extensions are used for the listed purposes. '''GetUserName''' is left installed but not enabled in LocalSettings. MyVariables is throwing on error in debugging.
* Composer based extensions
** [https://getcomposer.org/download/ Composer] - per [https://www.mediawiki.org/wiki/Composer/For_extensions Mediawiki] site in wiki root folder. Used to install Composer packages and dependencies
** [https://www.semantic-mediawiki.org/wiki/Help:Installation/Quick_guide Semantic MediaWiki] - whole site revolves around it
** [https://github.com/JeroenDeDauw/Maps/blob/master/INSTALL.md Maps] - For the embedded interactive maps
** [https://www.semantic-mediawiki.org/wiki/Semantic_Result_Formats Semantic result formats] - permits semantic queries to other formats, I know array type is used by complex templates but I'm sure others have been used as well
** [https://www.mediawiki.org/wiki/Extension:Semantic_Compound_Queries Semantic Compound Queries] - permits advanced queries notably used in complex map templates
** [https://github.com/ProfessionalWiki/ModernTimeline Modern Timeline Result Format] - Permits a more actively supported and better looking timeline for hike logs
* Manually installed extensions
** [https://www.mediawiki.org/wiki/Extension:NumberFormat NumberFormat] - Used to format numbers. SMW sum'd results are not natively able to be formatted. 
** [https://www.mediawiki.org/wiki/Extension:Page_Forms/Download_and_installation Page Forms] - Makes the form editing of pages possible
** [https://www.mediawiki.org/wiki/Extension:Arrays Arrays] - Used for array creation and manipulation, including this page
** [https://www.mediawiki.org/wiki/Extension:Header_Tabs Header Tabs] - Allows turning form pages (or really any page) into tabbed pages
** [https://www.mediawiki.org/wiki/Extension:MyVariables MyVariables] - Allows referencing logged in user for form automation used for links and forms to hike logs and lists
** [https://www.mediawiki.org/wiki/Extension:GetUserName GetUserName] - Alternative for MyVariables but doesn't have a "blank if not logged in" option or feature
** [https://www.mediawiki.org/wiki/Extension:SimpleTable SimpleTable] - Allows simple table definition, specifically easily working with a CSV list
** [https://www.mediawiki.org/wiki/Extension:UrlGetParameters UrlGetParameters] - Allows use of a GET parameter in a link to be used by the page code. Used for Hike Logs.
** [https://www.mediawiki.org/wiki/Extension:MediaFunctions MediaFunctions] - Can retrieve location from photo EXIF (and other information). Planned use for map charting photos including maintenance needs.

==System Maintenance==

===Upgrade/Reinstall===
Use to upgrade across major versions or to reinstall after a borked update.
<p>General wisdom is to wait for the x.1 release before upgrading.
<p>'''Note!''' The example commands below are using a page array variable. Edit the page to update the variable for your target installation to ease copy-n-paste of commands. Examples currently using <kbd>{{#arrayprint:mwInstallVersion}}</kbd>.
# Precheck!
## These steps have worked for upgrades in the past, but a reality check with any new versions and [https://www.mediawiki.org/wiki/Manual:Upgrading MediaWiki's Upgrade Procedure] is always prudent.
## Check requirements vs. what the current [[Special:Version|Version Page]] is showing! 
### Primarily PHP as the host's slow version updating and PHP's aggressive deprecation have been a problem.
### Verify used extensions are compatible with the MediaWiki version you are moving to. SMW and Maps are two that hook deep and seemingly subject to version requirements. (SMW v4.0.2 supports up through MW 1.37).
## Run the [[#Update extensions|Update extensions]] procedure below to ensure everything is up to date prior to upgrade. We will copy Composer and manual extensions from the current installation for ease of upgrade.
## Include running the maintenance update and runJobs.
# Get MediaWiki (per [https://www.mediawiki.org/wiki/Manual:Upgrading MediaWiki site])
## Download desired version from the [https://www.mediawiki.org/wiki/Download MediaWiki Site] using <kbd>wget</kbd> to the home directory
## Unpack using <kbd>tar -xvzf</kbd> (''e.g.'', <code>tar -xvzf ''{{#arrayprint:mwInstallVersion}}.tar.gz''</code>)
## Delete zipped tarball (''e.g.'', <code>rm ''{{#arrayprint:mwInstallVersion}}.tar.gz''</code>)
# Copy customized files to new install (per [https://www.mediawiki.org/wiki/Manual:Upgrading MediaWiki site])
## Copy Localsettings.php (''e.g.'', <code>cp ~/public_html/clubwiki/LocalSettings.php ''{{#arrayprint:mwInstallVersion}}''/</code>)
## Copy kml folder (''e.g.'', <code>cp -R ~/public_html/clubwiki/kml/ ''{{#arrayprint:mwInstallVersion}}''/</code>)
## Copy Images folder (''e.g.'', <code>cp -R ~/public_html/clubwiki/images/ ''{{#arrayprint:mwInstallVersion}}''/</code>)
# Migrate manual extensions (Confirm this list is still accurate with the more actively used update procedure below)
## Copy Arrays (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/Arrays/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy HeaderTabs (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/HeaderTabs/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy MyVariables (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/MyVariables/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy GetUserName (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/GetUserName/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy NumberFormat (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/NumberFormat/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy PageForms (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/PageForms/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy SimpleTabs (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/SimpleTable/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy UrlGetParameters (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/UrlGetParameters/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
## Copy MediaFunctions (''e.g.'', <code>cp -R ~/public_html/clubwiki/extensions/MediaFunctions/ {{#arrayprint:mwInstallVersion}}/extensions/</code>)
# Migrate Composer (can also follow Mediawiki recommendations, but if you updated extensions first, this should be fine)
## Copy composer.local.json (''e.g.'', <code>cp ~/public_html/clubwiki/composer.local.json ''{{#arrayprint:mwInstallVersion}}''/</code>)
## Copy composer.phar (''e.g.'', <code>cp ~/public_html/clubwiki/composer.phar ''{{#arrayprint:mwInstallVersion}}''/</code>)
# Move over to new install (per [https://www.mediawiki.org/wiki/Manual:Upgrading MediaWiki site])
##Move the existing installation to a temporary backup folder <code>mv ~/public_html/clubwiki/ OLD.yyyymmdd.clubwiki</code>
## Move the new installation to the public folder <code>mv ''{{#arrayprint:mwInstallVersion}}/'' ~/public_html/clubwiki</code>
# Finish by repeating [[#Update extensions|Update extensions]] again. This will force composer to install composer packages and needed dependencies. Again include running the maintenance update and runJobs to complete the upgrade (instead of the web based upgrade).
# Check [[Special:Version]] and a page or two to confirm things are still working.
# Lessons of the past...
## If upgrade stalls to white screen, likely a specified extension is not installed, check list and add as needed
## May need to ctrl-shift-R to force reload pages to avoid seeing errors
## Maps may instead display "Your browser is not compatible with Google Maps v3." but I think it goes away after a few minutes to hours.
# Done!

===Update MediaWiki===
Patch - Available for point releases. Details on the [https://www.mediawiki.org/wiki/Manual:Upgrading#Using_patch MediaWiki site]
# Download patch from the [http://dumps.wikimedia.org/mediawiki/ dumps site]
# <kbd>cd</kbd> to <code>cd ~/public_html/clubwiki/</code> directory (the one with LocalSettings.php).
# Download (<kbd>wget</kbd>) the patch file from the [http://dumps.wikimedia.org/mediawiki/ dumps site] and <kbd>gunzip</kbd> it <code>gunzip ''{{#arrayprint:mwInstallVersion}}.patch''.gz</code>.
# Use <code>patch -p1 --dry-run</code> to check what will be changed (''e.g.'', <code>patch -p1 --dry-run -i ''{{#arrayprint:mwInstallVersion}}.patch''</code>)
# If all is well, run <kbd>patch</kbd> again without <code>--dry-run</code> (''e.g.'', <code>patch -p1 -i ''{{#arrayprint:mwInstallVersion}}.patch''</code>).
# Check [[Special:Version]] and you should see the new version number in place.
# Delete patch files <code>rm ''{{#arrayprint:mwInstallVersion}}.patch''*</code>

===Update extensions===
'''NOTE''': I have often got errors or configuration screens from the site after updating extensions. These are typically resolved by running the maintenance routine below. Sometimes a single browser temporarily refused to work, yet a different browser behaved normally.
