Intermittent issue with generating mirrors list for older releases

Hi, there seems to be an intermittent issue when generating a list of mirrors for older releases that started around the 3rd of November. The following URL produced a list or mirrors yesterday:

https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2020-06/R/eclipse-jee-2020-06-R-macosx-cocoa-x86_64.dmg&format=xml

But today it's returning the following (truncated):

<?xml version="1.0" encoding="ISO-8859-1"?>
<mirrors>
...
<mirror url="/technology/epp/downloads/release/2020-06/R/eclipse-jee-2020-06-R-macosx-cocoa-x86_64.dmg" label="[]  ()" />
<mirror url="/technology/epp/downloads/release/2020-06/R/eclipse-jee-2020-06-R-macosx-cocoa-x86_64.dmg" label="[]  ()" />
<mirror url="/technology/epp/downloads/release/2020-06/R/eclipse-jee-2020-06-R-macosx-cocoa-x86_64.dmg" label="[]  ()" />
...
</mirrors>

For the 2020-09 release a list is returned but the 2020-09 content isn't there with the handful of mirrors i tested (those mirrors do have 2021-06, 2021-09 & 2021-12 releases) https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2020-09/R/eclipse-java-2020-09-R-macosx-cocoa-x86_64.dmg&format=xml

2020-12 also returns broken mirror urls https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2020-12/R/eclipse-java-2020-12-R-macosx-cocoa-x86_64.dmg&format=xml

And 2021-03 does as well https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2021-03/R/eclipse-java-2021-03-R-macosx-cocoa-x86_64.tar.gz&format=xml

Is this a known issue? Looks related to 'Download.e.o size too big for mirrors' #78 (closed) ?

Thanks, Shane

changed the description

Seems the mirror system is ignoring format=xml and, realizing there are no mirrors, proceeds to send the file. This is not likely a regression, but rather a newly discovered bug. I'll look at the code.

Indeed, this is a use case that hasn't surfaced yet.

@sclarke please try now. You should have an empty mirrors list.

Thank you @droy All good.

Hi @droy this request is now returning an empty list which is unexpected https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2021-09/R/eclipse-java-2021-09-R-macosx-cocoa-x86_64.dmg&format=xml

Oh snap. I made a boo boo.

@sclarke thanks for reaching out. I pushed a regression about 2 hours ago, effectively disabling all mirrors. And here I wondered where all our bandwidth went to.

Mirrors list is back. Amazing what one space can do.
