Wordpress Sitemap Plugin Update (2.0.2)
Thursday, 19 August 2021
We've finally got around to updating our WordPress plugin addressing a number of bugs which have prevented some people from upgrading without workarounds.
Again, we're sorry it has taken so long, this is due to juggling various priorities and personal issues.
In early 2021 we made one of the biggest updates to our plugin re-architecting much of it and adding new features and flexibility including :
- Support for sitemap index files
- Support for image sitemaps
- Support for news sitemaps
- Support for larger sitemaps
A patch release (2.0.1) addressed some bugs but others since came to light requiring manual patching or rolling back to a previous version which has been an issue.
We are hopeful that this 2.0.2 patch release has addressed the outstanding issues to enable more people to upgrade. Key issues addressed include:
- PHP debug / log errors xmlRenderer.php when images disabled.
- Post settings not updating.
- News sitemap missing language tag.
- News not working due to bad database upgrade script.
- Outstanding activation issues on network installs.
You can download the latest version from wordpress.

Overdue online update
Saturday, 14 August 2021
We've been working on an update for some time to address some bugs and performance issues since our last release. This lead to some pretty big rabbit holes and major reworks of code and re-architecting how we use Microsoft Azure infrastructure, which has consumed many evenings and weekends, but finally there is light at the end of the tunnel.
Most of the changes in this release were technical under the hood issues that many users wont appreciate although the service is running more smoothly and faster, not withstanding their may be teething issues as we migrate users on to the new release.
Key fixes and changes include
- Prioritization of sitemap jobs for contributors.
- Contributor can configure more concurrent requests for faster processing.
- Longer timeout periods for larger sitemaps.
- "My sitemaps" page performance improved.
- Fixed the transient download link issues.
Technical stuff.
Most of the time went in to key technical changes which aren't worth writing up in huge detail but for interest :
- Re-writing of the spider HTTP stack, in particular, moving to the new .Net SocketsHttpHandler to improve the performance of requests.
- Changing from exclusively in memory processing to streaming spider results disk, which allows for more concurrent processing and larger sitemaps without running in to memory issues.
- Migrating the entire spider process to Azure Functions to allow spider sessions to run for longer without timing out and dropping pages.
External link checker
One issue we have not been able to resolve is the performance of external link validation. We lost a lot of time to this one and despite re-writing our HTTP stack we were unable to resolve it. After many hours we discovered that the problem relates to an issue (feature) of Microsoft Azure. Microsoft is throttling DNS requests and so no matter how performant our code their DNS server is a serious bottle neck.
We have a number of strategies we are looking at to resolve this however it may take some time and unfortunately in the meantime we have disabled this feature to prevent it impacting on other areas of the service.
We haven't forgotten G-Mapper and Wordpress.
In better news, we will be adding a few new features and at some point hope to migrate this code over to G-Mapper so that our Windows users can benefit from these improvements. In the meantime, we're aware that our Wordpress users have been waiting on some bug fixes for some time and so this will be our next priority.
