could not release a new package with zest.releaser 6.8

[faassen]

I tried to release a new package to PyPI today (i.e. register it), but zest.releaser crashed. It crashed somewhere in requests-toolbelt trying to parse some JSON. Nothing appeared in PyPI. In the end I manually upload it using twine.

Do you still have some console output you could copy/paste?

(@mauritsvanrees, see https://twitter.com/faassen/status/819909529898979329 btw)

[faassen]

Nope, I'm afraid I don't, I am afraid I lost that terminal history.

Uploading a new package to testpypi works for me. But to PyPI I get a traceback:

Let me see what I can dig up with a pdb.

@mauritsvanrees: I suspect the json decoder gets a html error page instead of readable json. Somewhere in twitter @faassen mentioned a "this is deprecated" output from one of the URLs.

[mauritsvanrees]

I am trying to upload new package mauritstestpackage2. zest.releaser calls package_is_uploaded from twine, which downloads the url https://pypi.python.org/pypi/mauritstestpackage2/json, which gives a 404, which cannot be parsed as json.

Ah, it is basically this twine bug which I reported a while ago.

[mauritsvanrees]

I am preparing a pull request for zest.releaser to work around it.

[reinout]

@faassen: @mauritsvanrees fixes github issues faster than I react on twitter mentions :-)

[mauritsvanrees]

Huh, I thought I had created a pull request, but I only created a branch. The Travis tests pass. I will merge and release.

[reinout]

Ok

[mauritsvanrees]

I have release 6.8.1 with a fix.

[reinout]

Hurray!

[tkimnguyen]

Interestingly I had to specify 6.8.1 explicitly, otherwise buildout pulled down 6.8... but I confirm 6.8.1 fixes said problem! Thx @mauritsvanrees
