Conan: Downloading fails with Python 3.4, succeeds with 2.7

[mikedld]

I've seen #235 and #349 but my issue isn't connected to file size. I've created a package for SNMP++ and the source tarball for version 3.3.5 there is just 657493 bytes in size. When installing and using Conan with Python 3.4.5, I'm getting this error:

Using Python 2.7.12 the package builds just fine.

I'm using Conan 0.12.0 on Gentoo Linux x86_64 (installed with pip). Tell me if you need more information on this.

Thanks for telling, no indeed it doesn't seem related to those issues. We are just in the process of changing all downloads and uploads to streaming from/to disk, but it is not related, as the tools.download() is separate functionality. Yes, seems a bug with Py3, will look, thanks!

[memsharded]

Issue fixed, but not released yet. Can run from develop branch from sources.
Will be released in conan 0.13.

[memsharded]

Released in conan 0.13.1

[levon-vardevanyan-solarwinds]

seems like this one is broken again somehow.
reproduced with 0.28.0 on ubuntu 17.10 and centos7 (python2.7).
installing 0.27.0 from source fixed the issue.
Let me know if you need more info.

[memsharded]

It is not exactly the same error, it seems. A minor release is open to fix this: https://github.com/conan-io/conan/tree/release/0.28.1

Can you please tell me which zip_name file are you trying to download, to check?
We might release it today or tomorrow, I will do an extra check with your info, thanks!

[memsharded]

I have tried with a couple of files from that domain, and not able to make it fail yet.

[levon-vardevanyan-solarwinds]

have u tried that topicstarter's tarball? even size in log is the same 657493.
now i'm trying to dive a little bit deeper into the package creation domain to understand the problem better and to be able to help u :)

[memsharded]

Link please? I am checking http://www.agentpp.com/download.html, but cannot see that topicstarter tarball. Thanks!

[levon-vardevanyan-solarwinds]

http://www.agentpp.com/download/snmp++-3.3.5.tar.gz and a link from the first message works for me.

[memsharded]

Confirmed. I have added 2 extra tests, this should be fixed in next 0.28.1 (tomorrow)

[levon-vardevanyan-solarwinds]

Cool! That was fast :) Thanks.

[memsharded]

@levon-vardevanyan-solarwinds Released 0.28.1 fixing this, please try!

[levon-vardevanyan-solarwinds]

tried version installed by pip install conan = 0.28.1, looks great so far.
seems like u fixed that, thank you.
