The [Wayback/Archive] Embarcadero/IDERA Documentation Wiki has been mostly down since March 3rd, 2022 (not the main page, but almost all other pages are).

I modified [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring to show the actual status of a deeper page as the (mostly static) top page is up, so monitoring that is useless as the deeper pages are down.

The deeper pages are dynamic and require a functioning MySQL database connection. That connection is mostly down (the error message is not clear, so this could be a network or a database server problem, or maybe even a loadbalancer gradually entering bit heaven).

Since it had been down for like 6 days in February*, I’d expect Idera to keep an eye on it and prepare for more downtime. Apparently that’s either not a 24×7 thing for them or they missed the “pre” in preparation as it is dead-silent on .

It also runs on an unsupported version of Mediawiki 1.31** which by itself does not explain the outage, but does indicate that their idea of handling their internal lifetime management is different than what they advocate to clients in their software subscription model, see [Wayback/Archive] Delphi – Embarcadero store, [Wayback/Archive] Update Subscription – Embarcadero and [Wayback/Archive] Special Offers on RAD Studio, Delphi & C++Builder – Embarcadero:

Can I obtain updates and hotfixes without a subscription?

An active update subscription is the only way to obtain updates and hotfixes.

Back in the days Embarcadero were keen in advocating life cycle management. Maybe time to show they indeed still understand what that means.

The original 7 day outage from 20220217-20220224 was reported at [Wayback/Archive] docwiki.embarcadero.com is not working – General Help – Delphi-PRAXiS [en].

I amended some information at [Wayback/Archive] docwiki.embarcadero.com is not working – Page 2 – General Help – Delphi-PRAXiS [en] and redirected a [Wayback/Archive] UptimeRobot | Free Website Monitoring link at [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring.

A few hours later it sort of looked to be operational again, but in the monitor actually showed it was having outages every few minutes for intervals of 5-45 minutes: [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring.

The source of the docwiki home page at [Wayback] docwiki.embarcadero.com/ shows this:
   <meta name="generator" content="MediaWiki 1.31.1">
Mediawiki 1.31.1 is not even the most recent LTS version 1.31.16 (see [Wayback/Archive] Release notes/1.31 – MediaWiki), so here might even be CVE vulnerabilities.

When choosing for LTS, then they should go to the latest of 1.35 (at the time of writing 1.35.5), see [Wayback/Archive] Release notes/1.35 – MediaWiki and [Wayback/Archive] Version lifecycle – MediaWiki:

Blue: Alpha development

Grey: Release development

Green: Stable release

Orange: Long-term support release

…

A major release will be made every six months.

A long-term support release (LTS) will be made every two years. There will be a one-year overlap in LTS support. For example, 1.23 was supported until May 2017. 1.27 was released the year before, so that people have it available as an LTS to move to and a year to make the transition.

Older Mediawiki versions can be vulnerable to attacks, even LTS ones when you do not stay on the most recent build inside an LTS branch.

Some related tweets and sites:

Failing method is called by the class starting at [Wayback/Archive] …/mediawiki/blob/1.31.1/includes/cache/localisation/LCStoreDB.php – Line 28.

The selectField method is at [Wayback/Archive] mediawiki/Database.php at 1.31.1 · wikimedia/mediawiki – Line 1446.

Related class documentation (with diagrams how they related to the rest of the Mediawiki system) is at:

Based on these and some of the requests succeeding, there seemed to be three possibilities:

Sometimes the load balancer cannot get a database connection at all
Sometimes the load balancer gets a valid connection and that connection then fails returning a query
Sometimes the load balancer gets a valid connection and that connection succeeds returning a query

But then [Wayback/Archive] Remy Lebeau (of Indy fame) kicked in with another backtrace at [Wayback/Archive] docwiki.embarcadero.com is not working – Page 3 – General Help – Delphi-PRAXiS [en]:

It is not just the load balancer that is having issues. For example, trying to access several pages today, I’m running into a new kind of error:

Look at the table names:

lib_sydney_en_l10n_cache
rad_xe8_en_l10n_cache
cde_alexandria_en_l10n_cache

They have three different prefixes (lib, rad and cde) and three different product codes (sydney, xe8 and alexandria).

This looks like a a setup with each product version having at least three different Wikimedia databases each having an l10n_cache table. Searching for [Wayback/Archive] l10n_cache – Google Search resulted in [Wayback/Archive] Manual:l10n_cache table – MediaWiki (which describes the table for all ranges of Mediawiki versions) and a whole load of pages with various circumstances in which people bump into missing this table.

Then I looked into the current status monitor to see is anything substantial had changed since yesterday. And it did.

Current status

At [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring – docwiki https it looks someone started working on it almost 15 hours ago:

5012.65ms / 10372.00ms / 214.00ms

I really really hope they know what they are doing, as right now the databases don’t look well and things have not improved for more than 15 hours (I was interrupted while writing this reply).

Opinion

That their largest and most important site is still failing and there is no communication from Embarcadero on social media or 3rd party forums (they do not even have their own [Wayback/Archive] Embarcadero Discussion Forums and direct to 3rd parties at [Wayback/Archive] Community | Embarcadero RAD Studio, Delphi, & C++Builder Blogs) is inexcusable.

I searched social media. The only query returning anything useful was [Wayback/Archive] docwiki – Twitter Search / Twitter which only this Embarcadero response:

[Wayback/Archive] MarcoCantu on Twitter: “Yes, there is a technical issue with docwiki server our IT team is looking into” / Twitter (20220216)

The only forum response was on the German Delphi Praxis forum: [Wayback/Archive] Delphi-PRAXiS – Einzelnen Beitrag anzeigen – Delphi Dokumentation down?

[Wayback/Archive] Check What Version of MediaWiki You Are Running – White Fir Design
In the source code of the website’s pages the version number is listed in the following line:
```
<meta name="generator" content="MediaWiki 1.25.1">
```
- The JavaScript to grab this from a page is document.querySelector('meta[name="generator"]')?.content
- A Bookmarklet to show it is this: javascript:{v=document.querySelector('meta[name="generator"]')?.content; prompt("Mediawiki version",v)}

PS

Based on the above small list of database names, I am saving as much error information I could get below.

Permutations table

Delphi version
version nnemonic
Documentation part
Documentation mnemonic
Languages

Not sure if Delphi XE4 originally was intended to be XE 3.5 (I remember it adding support for iOS and dropping support for .NET), but the name part xe35 in the Mediawiki database names is certainly is odd.

Not sure about the xe5p name: I can’t imagine they wanted to release only Professional versions or bring this out as a patch for XE4.

Lists of used `wikidb.*_l10n_cache` database names

Note that the more recent product version names are stored inside l10_cache, whereas for older they are part of either the page markup or configuration so they end up in the link title.

Odd

An URL like https://docwiki.embarcadero.com/CodeExamples/Sydney/de/Special:Search/Main%20Page redirects to https://docwiki.embarcadero.com/CodeExamples/Sydney/e/Special:Search/Main%20Page which uses e as language code (which un turn is not a valid language).
[Archive] Internal error – RAD Studio XE Code Examples: 2010 cde_xe_en_l10n_cache (the 2020 URL returns an XE page with an XE database)
[Archive] FMX – RAD Studio API Documentation: FMX

The revision #734832 of the page named “FMX” does not exist.This is usually caused by following an outdated history link to a page that has been deleted. Details can be found in the deletion log.
Another old Mediawiki version found in a 20190305 archived version of [Archive] RAD Studio API Documentation Rio Libraries

/var/www/html/shared/BaseWiki27/skins/DuoBook2/DuoBook2.php: Too few arguments to function DuoBook2Template::displayPrefs(), 0 passed in
- It also got archived that day in the WayBack machine as web.archive.org/web/20190305081418/https://docwiki.embarcadero.com/Libraries/Rio/en/Main_Page and to no surprise contained
```
<meta name="generator" content="MediaWiki 1.27.4"/>
```
  which at the time of use was an older unsupported version of the LTS 1.27 branch (see [Wayback/Archive] Release notes/1.27 – MediaWiki: at that time 1.27.7 was current) which back then was vulnerable to [Wayback/Archive] CVE-2018-0505 – OpenCVE.
  Between web.archive.org/web/20190505083825/http://docwiki.embarcadero.com:80/Libraries/Rio/en/Main_Page and web.archive.org/web/20190601083408/http://docwiki.embarcadero.com:80/Libraries/Rio/en/Main_Page they upgraded to the LTS version 1.31.1 (which got released at 20180613 and made 1.27.7 unsupported at 20190613 as Mediawiki has a 1-year overlap of LTS versions)
```
<meta name="generator" content="MediaWiki 1.31.1"/>
```

There is also a main Wiki site (of which I do not have the database name yet) which has pages like
