zlib.output_compression should be disabled in php53.ini and php53-cli.ini

Possibly relevant is that we have the private directory outside the webroot, with the setting enforced via local.settings.php

Do we need to make some changes to the nginx config to account for this?

Have tested this using the default private filesystem settings and locations of Barracuda/Aegir and swf files are still not getting sent properly

Diffed example in this image:
https://www.evernote.com/shard/s2/sh/59caa1d6-f32e-42cb-a21b-add74faba95...

This appears to be caused by gzip compression on the swf files, if I comment out the following line in /var/aegir/config/server_master/nginx.conf then the swf files are served and display properly:

#  gzip_types        text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

Tipped off via http://patrickmcd.com/2009/04/20/flash-preloading-errors-turn-off-gzip/

Is there a way we can only disable gzip on swf files?

This is private filesystem on Drupal 6 so the files do get sent via Drupal.

We haven't created any module that does it.. just vanilla private filesystem in D6.

Interestingly, since disabling gzip, the files being received by FF, Chrome, and Safari are alll different sizes for the exact same file.

FF is the only browser displaying the file in full, Chrome and Safari downloads incomplete versions of the file.

output from Live HTTP extension shows that it is still being gzipped :/

Had to change the following setting to "off" in /etc/php/fpm/php.ini to resolve this:

zlib.output_compression = Off

has this made it to stable yet?

is there any way to see when the last stable was pushed?

Or ideally something that we can subscribe to via RSS..?

thanks
