Finish renaming Piwik to Matomo everywhere

[mattab]

In January 2018 we announced that Piwik is now Matomo 🎉

As part of the renaming efforts we're updating all our websites, tools, core app, plugins, ie. everything!

Renaming checklist left to do:

• make the build files matomo.zip and matomo.tar.gz, as well as the directory inside the builds should be called matomo
• plugin CustomPiwikJs to be renamed eg. CustomJsTracker --> see Rename CustomPiwikJs plugin to CustomMatomoJs (or CustomTrackerJs) #13604
• plugin AnonymousPiwikUsageMeasurement to be renamed (out of scope for Matomo 4)
• HTTP Tracking API endpoints: piwik.js and piwik.php
• JavaScript tracking sdk with objects like Piwik and window.Piwik and methods like getPiwikUrl
• Plugin developers, core platform uses namespace Piwik + some objects called "Piwik"
• Rename events eg Piwik.getJavascriptCode
• cookie names eg piwik_auth
• URL parameter like piwik_campaign to also support matomo_campaign --> done with Allow using matomo prefixed parameters for campaigns such as matomo_campaig/mtm_campaign #15957
• HTTP API methods eg. ExampleAPI.getPiwikVersion -> 3.3.0
• DB prefix like piwik_ -> 3.3.0
• Remove --piwik-domain console parameter (see Renames console to Matomo #13192) - Will be done with Removes deprecated console param --piwik-domain #15503
• After a successful auto-update, the screen shows Piwik is now Matomo and a big image. Be good to remove both. --> Will be done with Removes Piwik is now Matomo from update screen #15504
• Marketplace URL parameters like "piwik_version"
• plugin.json parameters like require "piwik"
• CSS classes etc (out of scope for Matomo 4)
• angular directives like piwik-foobar (out of scope for Matomo 4)
• Remove Piwik font (already "renamed" to Matomo in Renames piwik font to matomo #12489)
• Tracker proxy: Add matomo.php with keeping BC + Update [faq])https://matomo.org/faq/how-to/faq_132/) Update file names to matomo.* + FAQ tracker-proxy#55
• update all doc blocks with new name / url --> Update codebase doc blocks with new name Matomo #15857
• ... and more

In the case of Matomo core platform we want to keep things backward compatible for users including HTTP APIs users or users of the JavaScript SDKs.

Assigning to Matomo 4.0.0 but hopefully we can tackle a few of the list, and make progress on the others, during Matomo 3.x 🚀

Hey there,
not sure if there's a separate repo for the website (matomo.org, didn't found one), but I think it will fit in here.

On the main page, there's this animation:

On the truck it say's Piwik, so that should be changed at one point in the future. :-)

Cheers!

As part of this issue it be important to look at which ones are easy and quick to do. The rest we'll do as part of Matomo 5.

[tsteur]

for tracker created matomo-org/tracker-proxy#61

I reckon we can move the rest to Matomo 5? The only question would be wether we want to release another Matomo 2 and Matomo 3 update with the legacy auto loader: https://github.com/matomo-org/matomo/blob/4.x-dev/LegacyAutoloader.php#L17

This way should we ever change the namespace then it would cause less upgrade issues.

@sgiehl @mattab I reckon it could make sense to add the autoloader and release new version also for Matomo 2.* users

[sgiehl]

@tsteur Yes. Guess it makes sense to release new versions for 2.x and 3.x with the autoloader, so we have smoother updates later...

[tsteur]

@sgiehl created this for 3.x-dev: https://github.com/matomo-org/matomo/compare/3.x-dev...legacyautoloader?expand=1 would create the same for 2.x-dev... do you reckon this would help?

Generally thinking the autloader needs to work both ways Piwik -> Matomo and Matomo -> Piwik

• Core updater runs with 3.x, all files from Matomo are being updated
• Now it tries to request \Piwik\Http class in https://github.com/matomo-org/matomo/blob/3.13.6/plugins/CoreUpdater/Updater.php#L131
• Because the file core/Http was replaced this file will contain \Matomo\Http... and no longer \Piwik\Http...
• The error would not be solved by this legacy autoloader unless we add alias as needed both ways (which I now did in the updated code base)

On another note noticed there is also interface_exists. Hoping we won't run into any issues around interfaces but luckily we don't use them much :)

[sgiehl]

Aren't we running most of the update process on the new code base? 🤔
But guess it makes sense to have the autoloader in both ways, to be sure there can't be any renamed class missing...

[tsteur]

FYI we basically need to release a Matomo 2 release and then we can move this issue into Matomo 5 milestone.

I just updated to Matomo 5.0.1 and post-update "Matomo Changelog" panel says "See the latest changes in Piwik.". Doing a quick scan of the Web tree, I found the HTML code in /tmp/cache/tracker/matomocache_RSS_d88870a6de03bc454328f6b17452cb70.php so I'm guessing this is supplied by matomo.org and then cached locally. I think this might be the first time I've seen an incorrect visible textual reference to Piwik after logging in to our local Matomo instance.
