Description Luca Olivetti 2017-10-25 13:08:33 CEST

The guest portal in unifi (java server with built-in tomcat) doesn't work with this version of zlib (it gives an ERR_CONTENT_DECODING_FAILED or en equivalent message both in chromium and firefox).

The same upstream commit that fixes it in ubuntu also fixes it in mageia 6 (tested with a locally build rpm)

Thanks for the test.

You might want to consider becoming a Mageia packager, so that you can push such fixes to 6/updates_testing :-)

Our zlib maintainer maintains way too many packages, I think he'd be happy to get a hand.

uploaded to 6/updates_testing ad subrel 1 / rel 4. Please test.

Comment 3 Luca Olivetti 2017-10-26 17:28:28 CEST

I can confirm that lib64zlib1-1.2.11-4.1.mga6.x86_64.rpm fixes the issue.
@Marja, sorry, I cannot commit to be a packager

Comment 4 David Walser 2017-10-26 18:27:19 CEST

Luca, maybe you can write an update advisory explaining what just got fixed and assign this bug to qa-bugs@ml.mageia.org, so the update can be released.

Updated packages:
libzlib1-1.2.11-4.1.mga6
libzlib-devel-1.2.11-4.1.mga6
libminizip1-1.2.11-4.1.mga6
libminizip-devel-1.2.11-4.1.mga6

from zlib-1.2.11-4.1.mga6.src.rpm

Whiteboard: (none) => MGA6-64-OK

Comment 5 Luca Olivetti 2017-10-26 19:31:10 CEST

I'll try:

zlib 1.2.11 breaks the gzip content compression in UniFi guest portal (tomcat server) and probably other java tools that rely on zlib.

This package applies a patch from upstream that fixes the issue.

Comment 8 Lewis Smith 2017-12-21 14:57:20 CET

Validating as it already has a 64-bit OK, and is obscure.
