Revisiting ActivePerl… Part Two!

In our previous article, we took an in-depth look at ActivePerl.

ActivePerl is a way of installing a Perl environment under Windows, and Perl is the underlaying programming language that our MIDAS software is written in.

In essence, we felt we could no longer recommend ActivePerl to our self-hosted customers looking to install our room booking software on their Windows servers.

Well, ActiveState (the developers of ActivePerl) took notice of our article and have quickly reached out to us…

ActiveState’s Response

Pete Garcin, Director of Product at ActiveState reached out to us:

I saw your blog post about revisiting ActivePerl — it was great to see the engagement you had with the platform and the process you went through trying to get your build to work. It’s unfortunate that you ran into issues during that process though!

One of the goals of the platform is to provide a simple, reproducible process for generating builds from an expansive catalog. While it’s not always possible to keep 100% of the catalog building 100% of the time, we do our best to keep critical packages running.

Since the time you attempted your build, DBD::MySql and the maria-db-connector have been fixed (they were transiently broken) and one of our build engineers bumped the timestamp on your project so that now all of your projects for later versions should work. If you use 5.32 or newer, it ships with the mysql client DLL by default! In the future, making any change to a project will move the timestamp forward so that you pick up new changes to the catalog.

Also, you are free to use 5.32.1 or 5.34.0 — as both are now classified as out of beta (website might lag behind slightly). In fact, we highly recommend using one of the newer versions as the build experience is much faster and they also include the mysql DLL.

Also, if you’re distributing to your end users, our CLI provides a super simple way for anyone to set up the environment without needing to distribute a full installer — and they can also receive updates and stay sync’d. For modern versions of Perl (5.32+) you’ll see the instructions on how to install the CLI and the build on the platform dashboard in the Downloads tab.

Again — sorry to hear you had a rough experience creating your build, we’d love for you to try again with the updated projects and always happy to help work through any issues with you! Feel free to reach out any time.

– Pete Garcin, Director of Product, ActiveState

ActiveState’s CTO, Scott Robertson, also reached out:

Thanks for the amazing write up, really sorry you had a bad first impression. Even though ultimately we didn’t win you on the first shot I took heart that you’re starting to see the vision to our ambition when you say “We admit, we were actually a little excited – we appeared to have a custom Windows distribution of..”.. That’s the goal!

You’ve noted the number of packages we now support is over 100k! We’re coming pretty close to our goal now of being able to build 100% of CPAN in a secure reproducible way including all native dependencies. Something Strawberry perl can not claim. Unfortunately we’re still experiencing some growing pains going from 500 packages to over 100k and supporting every version the night it’s dropped. Looks like when you tried this project MariaDB updates entered our catalog and were broken. We have since fixed them. The post you found in our community forum was way out of date. We’re working on producing better support materials, but in the meantime know we’re here to help.

– Scott Robertson, CTO, ActiveState

Analysis

First of all, we have to give credit to ActiveState for reaching out to us so quickly. We certainly weren’t expecting that, but it’s encouraging to see their engagement.

Secondly, it would appear – at first glance at least – that ActivePerl 5.32 and 5.34 do now successfully build on the ActiveState platform.

So let’s take a look…

Missing stand-alone installers

Here’s what the “Download Builds” tab on the ActiveState platform looks like for our ActivePerl 5.28.3 build:

.exe and .msi Windows installers are available for ActivePerl 5.28.3
.exe and .msi Windows installers are available for ActivePerl 5.28.3

Notice that there are two install methods offered; “Download Installer” and “Install via Command Line”.

The “Download Installer” section contains download links for standalone Windows installers for our ActivePerl 5.28.3 build.

The “Install via Command Line” section allows the build to be installed from the command line using Windows PowerShell and ActiveState’s “State Tool“.

Now, let’s be realistic; the average non-tech savvy user will always opt for a familiar Windows Installer over having to use Windows PowerShell to execute arbitrary commands.

So it’s strange and very disappointing that no stand-alone installers appear to be provided for our 5.32/5.34 builds:

No stand-alone installers for Windows are provided for ActivePerl 5.34
No stand-alone installers for Windows are provided for ActivePerl 5.34

Thinking this may be a glitch, we triggered a re-build of our ActivePerl 5.34 package on the ActiveState platform. This appeared to successfully build, but again no standalone Windows installers were generated.

We questioned this with ActiveState’s CTO who told us:

Installers vs State tool: It will be State tool only going forward for free versions. The service and command client is meant for developers. Installers are a paid option.

Scott Robertson, CTO, ActiveState

This is clearly a very recent decision which isn’t made clear on their website. In fact, the automated email notification the platform sent us when the re-building of 5.34 was complete, still asserts that you can “download the installer”:

Email notification from ActiveState indicating that a stand-alone installer is available
Email notification from ActiveState indicating that a stand-alone installer is available

Sadly, the lack of any standalone .exe/.msi installers for ActivePerl being made freely available going forward is a major block for us to recommence recommending ActivePerl again to our self-hosted MIDAS customers.

However, we were still curious ourselves as to whether the previous issues with lack of MySQL/MariaDB support had indeed been fixed in this 5.34 build, so we decided to try a test installing using Windows PowerShell to install ActivePerl’s “State Tool” and configure our 5.34 build.

Here’s how we got on:

Installing via Windows PowerShell

We opened a Windows command prompt and then pasted in the command ActiveState provided to “Install via Command Line”.

The result was a spiel of console output that would baffle most:

Console output from installing ActivePerl via the command line
Console output from installing ActivePerl via the command line

…to be honest, we’re not even sure if we understand all of that… and we’re seasoned Perl developers!

Anyway, the console output ended by informing us that we were “Activated”.

So Perl 5.34 was now installed… right?(!)

We weren’t sure, so to test, we created a very simple .pl script that would print the words “Hello World!” in the browser, and saved this to our test Apache web server’s htdocs.

This very simple .pl script contained just two lines:

#!/usr/bin/perl

print "content-type:text/html\n\nHello World!";

Trying to locate Perl

Now, let’s talk shebangs (no, not the 2000 hit by Ricky Martin!).

In Perl, the “shebang” refers to the very first line of any Perl script. It informs the web server as to the whereabouts of the perl installation to use.

On Linux servers, Perl may typically be located at /usr/bin/perl, therefore, the first line of any Perl script (known as the “shebang” line) should read:

#!/usr/bin/perl

On Windows servers, Perl was traditionally located at C:\Perl\bin, C:\Perl64\bin, or C:\Strawberry\perl\bin, and so the shebang could read something like:

#!C:\Strawberry\perl\bin\perl.exe

However, Apache servers support a really cool configuration option called “ScriptInterpreterSource Registry“. What this does is instruct Apache to simply ignore the “shebang” line, and instead determine the location of Perl based upon a Windows registry value (which should be set when Perl is installed).

That has the advantage that user’s don’t then need to set/change, or indeed care about the “shebang” line in Perl scripts, they should just work regardless!

That’s why we recommend enabling this config option when installing and configuring Apache on a Windows server.

So we tried accessing our simple “hello world” Perl script in our browser. This resulted in an Internal Server Error:

Internal Server Error when executing a .pl script
Internal Server Error when executing a .pl script

Upon investigation, it would appear that during install of ActivePerl, no registry value was set to allow Apache’s “ScriptInterpreterSource” directive to determine where Perl was located.

So we then had to find the location of the perl.exe executable on our test server and manually update the shebang line of our “hello world” script.

There was no obvious C:\Perl, or C:\Perl64 or even C:\ActivePerl directories present, so we had to search the entire C:\ drive on our test server for “perl.exe”. We eventually found perl located under:

C:\users\wdagutilityaccount\appdata\local\activestate\052e8766\bin\perl.exe

So the “shebang” line we needed to add to our “hello world” perl script was the instantly forgettable(!): #!C:\users\wdagutilityaccount\appdata\local\activestate\052e8766\bin\perl.exe

Anyway, this at least allowed our hello world script to execute and correctly print “Hello World” to the browser.

The next stage was to try running our Server Readiness Tool.

Running our Server Readiness Tool

Our Server Readiness Tool is a perl script that our customers can freely download and access (via their browser), and which checks that their server is correctly configured in order to install MIDAS.

As part of these checks, the tool identifies any missing Perl modules which MIDAS requires.

To our surprise, running this tool indicated a number of missing modules, which we thought had been included in our custom ActivePerl build:

Perl modules apparently "missing"
Perl modules apparently “missing”

We double-checked back on the ActiveState platform, and sure enough these modules appear to have been successfully included in our build:

DBD::MariaDb and DBD::mysql appear to have been included in the build
DBD::MariaDb and DBD::mysql appear to have been included in the build

So what was going on?

Digging a little deeper in Apache’s error logs revealed the following errors:

Can't load 'C:/Users/wdagutilityaccount/AppData/Local/activestate/052e8766/site/lib/auto/DBD/mysql/mysql.dll' for module DBD::mysql: load_file:The specified module could not be found at C:/Users/wdagutilityaccount/AppData/Local/activestate/052e8766/lib/DynaLoader.pm line 193.\r: C:/Apache24/htdocs/servercheck.pl

Can't load 'C:/Users/wdagutilityaccount/AppData/Local/activestate/052e8766/site/lib/auto/DBD/MariaDB/MariaDB.dll' for module DBD::MariaDB: load_file:The specified module could not be found at C:/Users/wdagutilityaccount/AppData/Local/activestate/052e8766/lib/DynaLoader.pm line 193.\r: C:/Apache24/htdocs/servercheck.pl

Can't load 'C:/Users/wdagutilityaccount/AppData/Local/activestate/052e8766/site/lib/auto/Net/SSLeay/SSLeay.dll' for module Net::SSLeay: load_file:The specified module could not be found at C:/Users/wdagutilityaccount/AppData/Local/activestate/052e8766/lib/DynaLoader.pm line 193.\r: C:/Apache24/htdocs/servercheck.pl

We checked, and verified that “mysql.dll”, “MariaDB.dll” and “SSLeay.dll” files were all present at the locations indicated.

Digging into line 193 of “DynaLoader.pm”, this section of code included the comment “Many dynamic extension loading problems will appear to come from this section of the code … often these errors are actually occurring in the initialisation C code of the extension XS file. Perl reports the error as being in this perl code simply because this was the last perl code it executed“.

So whilst ActivePerl appears to have technically installed the modules as part of the installation process, right now they’re broken and don’t work on Windows under ActivePerl 5.34!

…and the previous “workaround” of grabbing the “libmysql__.dll” file from a Strawberry perl installation and placing that within the ActivePerl installation also didn’t resolve the issue.

Once again, we have a broken and unusable ActivePerl installation.

In conclusion…

ActiveState’s prompt engagement with us is very welcome and demonstrates that there is still at least some interest there with regards to Perl.

However, we’re sad that they still don’t have an up-to-date version of perl for Windows users that works with MySQL/MariaDB.

It was extremely disappointing when ActiveState abandoned their popular free “Community Edition”.

That disappointment has been further compounded now by the knowledge that going forward ActiveState have made the commercial decision to discontinue being able to build Windows .exe/.msi standalone installers, unless you pay.

This makes ActivePerl a far less attractive option to us.

Why would we want to spend thousands of dollars a year in order to “build” a user-friendly ActivePerl Windows installer for our self-hosted customers to use, when our customers can simply grab and use Strawberry Perl’s free Windows installer.. (and in doing so end up with a Perl installation that actually works on Windows!)

Even if a tech-savvy customer was willing to go down the route of installing ActivePerl on their Windows server via the command line script – as things stand right now, they would have a broken installation that wasn’t capable of interacting with a MySQL/MariaDB database. Therefore, they wouldn’t be able to install and run a self-hosted MIDAS booking system.

Now, if ActiveState are committed to resolving these issues, then we’d be happy to take another look…. however, for us to be won over, ActiveState would also have to reconsider the decision to put standalone Windows installers behind a paywall!

Right now, we can’t see how we can recommend ActivePerl to our Windows-based customers going forward… which is sad, as for years we’d been big advocates of ActivePerl.

For any prospective customers who are interested in MIDAS and considering a self-hosted installation in a Windows environment, we recommend installing Strawberry Perl. Alternatively, you could consider our no-hassle cloud-hosted offering instead.

Revisiting ActivePerl

Perl is the underlaying coding language that our MIDAS booking software is written in.

When it comes to developing with Perl on Windows-based systems, there are broadly two options, as Windows doesn’t natively come with Perl installed (unlike Linux/Mac systems)

These two options are:

Installing either of these products on Windows provides a Perl environment.

Here at MIDAS HQ, as we primarily develop using Windows-based machines, we need a Perl environment to develop under.

For many years, we opted for ActivePerl, but at the start of 2020 we made the switch to Strawberry Perl. You can read more about this in our earlier Strawberry Perl vs ActivePerl post.

A year and a half on, and we’re still very happy with our decision to move to Strawberry Perl.

But in some spare time recently, we thought we’d take a look at what ActiveState have been doing with their ActivePerl product since we moved away from it….

ActivePerl Icon

It’s all about the packages…

There are over 100,000 additional Perl “modules” (or “packages”) available to enhance the “core” functionality of Perl.

Our MIDAS software requires a handful of these additional modules in order to function.

We originally loved ActivePerl as it made it really easy for our customers (and us!) to install these modules via the “Perl Package Manager” tool (or PPM) for short.

This unique feature of ActivePerl was sadly retired by the vendor (ActiveState) by ActivePerl 5.28.

From ActivePerl 5.28 onwards, if users wanted to install additional Perl modules they were encouraged to instead sign up for an ActiveState account. They could then “build” their own custom-build of ActivePerl containing the additional packages/modules they require.

This was a far less user-friendly to install Perl modules than it was to use PPM, where modules could be installed at any time with just a couple of clicks.

Anyway, we thought we’d try using ActiveState’s platform to generate a custom-build of Perl containing all the additional modules/packages which MIDAS requires.

Here’s how we got on…

Signing up for an ActiveState account

Signing up for an ActiveState account is required if you wish to “custom build” ActivePerl with the specific modules/packages you require. That is unless you have a GitHub account (which let’s face it, most of our customers likely won’t have) in which case you can just sign-in.

In order to download ActivePerl, you now need to sign up/in to ActiveState
In order to download ActivePerl, you now need to sign up/in to ActiveState

Having to sign-up and create an account to build/download Perl is a bit unnecessary in our view. You can, for instance, download Strawberry Perl without any of the hassle of having to create an account first.

Anyway, we created an account and logged in…

Configuring a new ActiveState build

Creating a new ActivePerl build was relatively straight forward – there was a big “Create a New Project” button.

Creating a new project on the ActiveState platform
Creating a new project on the ActiveState platform

This then allowed us to select a language – in our case, this was Perl and a Perl version.

Creating a new Perl project on the ActiveState platform
Creating a new Perl project on the ActiveState platform

The two most recent options (5.34.0 and 5.32.1) were flagged as “Beta”.

Perl 5.34 and 5.32.1 are currently classed as "Beta" by ActiveState
Perl 5.34 and 5.32.1 are currently classed as “Beta” by ActiveState

We therefore chose the highest version that wasn’t flagged as “in Beta”. This was 5.32.0.

Next, we could “Add package bundles”. We didn’t want this, as we wanted to add individual packages, so we unselected all package bundles at this stage.

We then selected the operating system we wanted our custom Perl build to be for (in our case, Windows).

Selecting a target OS for ActivePerl
Selecting a target OS for ActivePerl

Next up was “Project visibility” settings:

All projects on ActiveState are "Public" unless you have a "paid" plan
All projects on ActiveState are “Public” unless you have a “paid” plan

The “Project visibility” could only be set as “Public” (unless you opt for one of ActiveState’s paid plans). Finally, we gave our project a name and hit “Create Runtime”.

Adding packages

Once the project was created, we then needed to add the 24 additional Perl modules (packages) that MIDAS requires. These could either be added one at a time via the “Add Packages” button, or imported as a list via the “Import” button.

Adding "Packages" to Perl on the ActiveState Platform
Adding “Packages” to Perl on the ActiveState Platform

The platform then automatically resolved additional dependencies of the 24 packages we’d added, which was useful.

One other useful feature was that the platform indicated any CVE’s (Common Vulnerabilities and Exposures) for each package we were including.

Building the new build

Once all the packages MIDAS required had been added, it was then time to “build” our custom ActivePerl environment. Building indicated that it would take up to 20 minutes to complete, and the platform displayed build progress in real-time throughout.

Sadly though, our build failed!

Building ActivePerl 5.32.0 failed
Building ActivePerl 5.32.0 failed

The packages that failed related to Perl support for MariaDB databases. MIDAS supports both MySQL and MariaDB databases, so it was kinda crucial that our Perl distribution fully supported MariaDB. Anyway, the provided build logs shed no useful light on the root cause of the build failure, nor did ActiveState’s community forums.

Trying again…

We decided to try again. We created a new project, but this time selected an earlier version of Perl (5.28.3), and added in all our required packages.

This time the build completed in 23 minutes and 35 seconds, and provided us with .exe and .msi installer links.

Testing the build

We admit, we were actually a little excited – we appeared to have a custom Windows distribution of Perl that our self-hosted customers could install on their servers, and all the modules MIDAS requires would be there right “out of the box”. Our customers wouldn’t need to separately manually install any Perl modules.

So we proceeded to install this custom distribution on a test Windows server, and all seemed to initially go ok.

Once Perl was installed, we ran our handy Server Readiness Tool. This is a free tool we provide to those interested in running MIDAS on their own server. Amongst other things, the tool checks that all necessary Perl modules are available.

To our surprise, this indicated that two modules; DBD::mysql and DBD::MariaDB appeared not to be installed. These modules allow MIDAS to communicate with its back-end database.

Running our Server Readiness Tool under our custom ActivePerl 5.28.3 distribution
Running our Server Readiness Tool under our custom ActivePerl 5.28.3 distribution indicates problems with DBD::mysql and DBD::MariaDB

Trying other versions

Wondering if it may have been an issue with the .msi installer, we completely uninstalled Perl and tried again with the .exe installer link instead. This produced the same results.

We also then spent time and built identical packages on the ActiveState platform under both Perl 5.26.3 and also Perl 5.34.0.

The 5.26.3 build produced the same results as the 5.28.3 build. The 5.34.0 build just failed to build (just like the original 5.32.0 build).

We looked a little deeper into our test server’s error logs and discovered that a key component needed by the MySQL and MaraDB drivers was actually missing and hadn’t been included within the distribution.

The “workaround”

It seems like we’re not the only ones having issues using recent builds of ActivePerl built on the ActiveState platform with MySQL / MariaDB packages included. A number of people have posted with similar issues in ActiveState’s forums (like in this thread, and this thread).

The issue appears to be related to a missing MySQL “client library” .dll file that doesn’t get included with builds of ActivePerl.

Their best solution… install Strawberry Perl, grab the required “libmysql__.dll” file that gets installed with that, and copy the file over to your ActivePerl install!

So we tried this, and it did indeed resolve the issue. But just to be clear – right now…

In order for ActivePerl to work with MySQL / MariaDB databases you need to install Strawberry Perl!

Yes – seriously!!

Why would anyone want to do this? – it would just be easier to install and use Strawberry Perl and not even bother with ActivePerl!

Conclusions

We’re really saddened by the recent direction that ActiveState have moved in with ActivePerl, and their apparent lack of enthusiasm for and commitment to ensuring that it actually works with popular databases!

For over a decade, we used to exclusively recommend ActivePerl to our Windows-based customers. Last year we changed to recommending either ActivePerl or Strawberry Perl.

However, in August 2021, as things stand at the moment, we can no longer recommend ActivePerl (we’ve even now removed this recommendation from our website).

In summary…

  • ActivePerl 5.32 and ActivePerl 5.34 fail to correctly build at this time, so can’t be used for MIDAS.
  • ActivePerl 5.28 and 5.26 do build, but are missing a required MySQL client library. In order to use either of these builds, you’d also need to grab a .dll file from an install of Strawberry Perl.
  • The last known “working” version of ActivePerl is 5.24. ActivePerl 5.24 is now 5 years old, and is no longer available for download from ActiveState’s website.

So for any self-hosted customer wishing to use install our MIDAS scheduling software on their Windows server, we suggest you avoid ActivePerl and use Strawberry Perl instead.

Alternatively, you may wish to consider our cloud-hosted solution.

UPDATE: Since originally publishing this article, ActiveState have reached out. Read more in Revisiting Active Perl… Part Two!

MariaDB vs MySQL

Any software application that “stores” data in some way shape or form, needs a reliable and efficient way to do so. That’s where a database comes in!

MIDAS – our web based room booking and resource scheduling software – is no exception. Since 2012, for its database, MIDAS has supported MySQL. More recently we started supporting MariaDB too.

Last week we announced that we’d migrated all our cloud hosted customers to MariaDB.

In this post we thought we’d look a little bit closer as to the differences between MySQL and MariaDB.

MySQL What is MySQL?

MySQL is a database engine released under a GNU General Public License, and also available under a variety of proprietary licenses.

MySQL was originally owned and sponsored by the Swedish company MySQL AB, which was subsequently bought by Sun Microsystems, and which then went on to be ultimately acquired by Oracle Corporation.

In 2009, when it was announced that Oracle was to acquire Sun, the founder of MySQL wasn’t happy and so “forked” the MySQL project and created MariaDB… more on that later.

Today, MySQL is the second most popular database engine in the world.

Prominent users of MySQL include Facebook, Pinterest, Airbnb, Sony, BBC, Symantec, GitHub, and booking.com.

MariaDB What is MariaDB?

MariaDB is a community-developed fork of MySQL. One of its key attractions is that it is intended to always remain free under a GNU General Public License.

It was created by one of the founders of MySQL, who forked it due to concerns over MySQL’s acquisition by Oracle Corporation in 2009. The concerns centered around rumors that Oracle (who already developed a competing self-titled database product) wanted to kill off MySQL in order to let their own “Oracle” database thrive. In the end, that didn’t actually happen, but that fear was the initial main driving factor behind MariaDB initially.

MariaDB intended to maintain high compatibility with MySQL, ensuring it would be a “drop-in replacement” for MySQL. Whilst that’s still broadly true today, since its inception, the features of the two database engines have slowly diverged more.

MariaDB version numbers initially followed MySQL’s numbering scheme up to version 5.5. As such, MariaDB 5.5 for example offers all of the features that MySQL 5.5 offers.

Specific new features have since been developed in MariaDB, so its developers decided that a major version number change was necessary. MariaDB 10.0 was released in November 2012, whilst MySQL at that time remained at version 5.

New features are added more frequently to MariaDB than to MySQL. MariaDB development is also led by some of the original developers of MySQL, with many other contributors. MySQL on the other hand is now developed almost exclusively by Oracle’s own in-house team.

Prominent users of MariaDB include Google, Mozilla, and Wikipedia.

Popularity of MySQL and MariaDB

Whilst today MySQL is still the second most popular database engine in the world, its popularity has been slowly declining over the years. At the same time, interest in MariaDB (currently the 11th most popular database) has been steadily increasing.

A brief history of database evolution in MIDAS

Our web based room booking and resource scheduling software, MIDAS, has been in active development for over 15 years now.

To help ensure maximum server compatibility, in the early days of our software, data was stored in simple CSV (Comma Separated Value) files.

In 2010, we migrated data storage from CSV to XML (Extensible Markup Language) files.

Two years later, in 2012 – and to coincide with the release of MIDAS v4 – we made the switch to a MySQL database.

MIDAS Database Evolution
MIDAS Database Evolution

Read more: MIDAS v4 – Why the database change?

Between 2012 to 2019 we continued to develop MIDAS exclusively using MySQL as its back-end database.

In 2019 we started receiving queries from a couple of customers asking if we’d consider supporting other database engines, as they weren’t big fans of MySQL.

By this time, MariaDB was gaining in popularity, and as it was billed as a “drop in replacement” for MySQL, it seemed a logical choice to explore.

In 2020, we released MIDAS v4.24, with preliminary and experimental support for MariaDB.

In our own development environment here at MIDAS HQ, we ran both MySQL and MariaDB in parallel during 2020. During this time, MySQL remained as the “preferred” database engine we use for development and testing of our software.

At the beginning of 2021, we made the decision to switch our “preferred” development database engine over to MariaDB. (We still continue to run MySQL, but this is mainly just for testing purposes these days).

Why we moved to MariaDB?

MariaDB has a number of advantages over MySQL, including:

  • MariaDB offers improved performance in many scenarios.
  • MariaDB is community-driven.
  • MariaDB has 268 contributors vs 83 contributors to MySQL *
  • MariaDB is in more active development (MariaDB has 193,330 code commits – the latest was today, MySQL has 163,534 – the latest was 3 months ago *).
  • MariaDB is gaining in popularity.

* correct at time of writing

All these factors led us to decide to migrate our development environment over to MariaDB in 2021.

In July 2021, we also seamlessly migrated our cloud-hosted customers over to MariaDB.

Should I choose MySQL or MariaDB?

If you’re considering a self-hosted edition of MIDAS (remember that we also offer a cloud-hosted edition too!), our software currently supports both MySQL and MariaDB databases.

At the end of the day, it will come down to personal preference, but we like to give self-hosted customers a choice. So if you’re looking for a room booking system that’s compatible with either MySQL or MariaDB, choose MIDAS!

Migrating to MariaDB

Migrating to MariaBD

As of 4th July 2021, all our cloud-hosted customer’s MIDAS databases have been migrated across from MySQL to MariaDB.

MariaDB What is MariaDB?

MariaDB is a community-developed “fork” of the popular MySQL database engine.

It was created by one of the original founders of MySQL, who forked it over concerns surrounding MySQL’s acquisition by Oracle Corporation in 2009. These concerns centered around rumors that Oracle were considering killing off MySQL to prevent competition with their own “Oracle” database. In the end, that didn’t actually happen and MySQL continues to remain available. But MariaDB continues to gain in popularity year on year, and has a number of advantages over MySQL.

Why the move from MySQL to MariaDB?

  • MariaDB offers improved performance over MySQL in many scenarios.
  • MariaDB is community-driven, whereas MySQL is owned and developed by Oracle Corporation.
  • MariaDB has 268 contributors vs 83 contributors to MySQL *
  • MariaDB is arguably in more active development. (MariaDB has 193,318 code commits – the latest was today, MySQL has 163,534 – the latest was 3 months ago *)
  • MariaDB continues to gain in popularity.

* correct at time of writing

Now, we’ve been thoroughly testing MariaDB in our MIDAS development environment for well over a year now. In fact, it’s now become our “preferred” database engine over MySQL. We now only use MySQL for testing purposes. Because we now develop primarily using MariaDB, it made sense to move cloud-hosted customers over to this database engine too.

Will I notice any difference?

Our cloud-hosted customers may notice small performance improvements when performing certain operations in their online booking system. Other than that customers shouldn’t notice any other obvious changes.

That doesn’t mean that there aren’t any additional benefits to MariaDB though! One of the things we’ve now been able to do in to MariaDB is implement “data-at-rest” encryption.

Data-at-rest encryption

When it comes to encrypting data send over the internet, there are broadly two different types of encryption; encryption in transit, and encryption at rest.

Encryption in transit deals with the secure transmission of data between your browser and a server. For example, if you submit a form on a web page, the data you entered needs to be transmitted (or “sent”) to a server. If the form was on a web page severed from a URL beginning “http://”, the data is transmitted unencrypted to the sever. This means that they data you’re submitting could potentially be intercepted and read during transit.

A form submitted on a website accessed over httpS, with correctly configured security certificates, will mean than the data will be encrypted in transit to the server.

All of our cloud-hosted MIDAS systems are accessible over secure https only. We support the latest standards and protocols (including TLS 1.3), and disallow older/obsolete/insecure protocols (like SSL 2/3, and TLS 1.0/1.1). If you’re interested, you can view our A+ rating on SSL Labs.

Encryption at rest on the other hand deals with how data is actually stored on a server (i.e. on a physical disk). Data may be encrypted in transit, yet not encrypted at rest, or vice versa.

The most secure systems are those which encrypt data both in transit AND at rest.

As of 4th July 2021, we’re pleased to announce that all our cloud hosted customer’s databases are also now encrypted at rest too!

What about self-hosted customers?

This month’s migration from MySQL to MariaDB affects cloud-hosted customers only.

Self-hosted customers have a choice between either using MySQL or MariaDB for their MIDAS database.

We have no plans to discontinue support for MySQL in the foreseeable future, and will continue to provide support to customers who are using MySQL for their MIDAS booking systems.
