[Fusioninventory-devel] Fusioninventory agent 2.3.4 - 2.3.6 cannot download deploy files when GLPI+FI lies on IIS 8.0 server

[Ozy de Jong]

Hello,

I've struggled a lot with my GLPI+FusionInventory 2.1 installation which is hosted on a IIS 8.0 platform.
When trying to deploy files, if the files are big (let's say more than 1M), and there are is some routing / DSL equipment between the server and the client, i get SHA512 failure errors.
I tracked down the issue by enabling HTTP answer logging in FusionInventory::Agent::Task::Deploy::File by adding $self->{logger}->debug($response->dump); on line 107.

When i tried to deploy files, i got this HTTP answer from the server:

After searching i found there is a problem with libwww-perl since they changed the way binary files are encoded (see here htps://rt.cpan.org/Public/Bug/Display.html?id=91643 et htp://perlguru.com/gforum.cgi?do=post_view_flat;post=76109;page=1;sb=post_latest_reply;so=ASC;mh=25 )

I've replaced the libwww-perl files from my fusioninventory client with libwww-perl 5.834, and suddently everything worked out right.

The issue with libwww-perl isn't silll resolved in the latest strawberry-perl release 5.18.2.1 (i've tried the included libwww-perl too).
Is there any chance you may downgrade libwww-perl in the next FI agent until this bug gets resolved by perl people ?

If not, and as LWP is also a real headache for SSL connections, would it be possible to replace the file download process by curl instead of LWP ?

Thank you for advice,

Orsiris de Jong.
