mod_http2 1.8.3 issue with Option index +

[nono303]

I've just upgraded my version of apache from 2.4.23 to 2.4.25 (vc14 x64) and I've noticed a bug relating to mod_http2.
According to changelog https://www.apachelounge.com/Changelog-2.4.html nghttp2 had been upgraded to 1.17.0 from 1.12.0

=> [http2:info] AH03090: mod_http2 (v1.8.3, feats=, nghttp2 1.17.0), initializing...

In my case, I've multiple ssl vhost with 'H2Direct on' & 'Protocols h2 http/1.1' directives (all working fine with 2.4.23) but since upgrade, all (but only) location with 'Options +Indexes' directive fail to work (unable to connect from browser or curl)
Downgrading only mod_http2.so with the 2.4.23 one (on a 2.4.25 httpd binary) solve the issue.

WORKING : mod_http2.so (nghttp2 1.12.0 from 2.4.23 vc14 x64 distrib)

FAILING : mod_http2.so (nghttp2 1.17.0 from 2.4.25 vc14 x64 distrib)

Do you mean

  Options +Indexing

? With that I am not able to reproduce. Can you try to make a minimal vhost config where the problem occurs?

<Location />Options +Indexes</Location> exactly.
Effectively, with from scratch configuration I am not able to reproduce too...
So according to my configuration I (difficultly...) found which directive fails with new mod_http2.

Here is:

• Keep Options +Indexes in server conf or in any vhost
• Add directive HeaderName /HEADER.html according to https://httpd.apache.org/docs/2.4/mod/mod_autoindex.html#headername
• Create HEADER.html in the Document root with or without any content
• The issue appear for me, only with mod_http2 1.8.3

Can you reproduce?

Thanks! Yes, I can reproduce the error now. Will add that too my tests and see what I can do...

Hi,
I've just build mod_h2 1.8.5-git with httpd 2.4.25 (MSVC15 RC x64) and all works fine ;)
Thank's a lot!!
