problem with redirect

[boutil]

Hi,

when trying to run the "stupid" example, I encounter the following problem. It was working before. Is it related with a change on the ietf.org website? Does it have to be reflected somewhere in the code of kramdown-rfc2629?

It may be related to the following mail on the xml2rfc mailing list about a browser problem similar to the error message:

Hi Cédric,

Indeed, there is discussion today on the tools mailing list about a redirection problem, exacerbated by a certificate problem. I have to think about ways of making kramdown-rfc more robust to this kind of situation.

Grüße, Carsten

This appears to be a bug in the open-uri library, though.

Workaround at the moment:

XML_RESOURCE_ORG_PREFIX=https://xml2rfc.tools.ietf.org/public/rfc kramdown-rfc2629

(i.e., set the environment variable XML_RESOURCE_ORG_PREFIX to the value https://xml2rfc.tools.ietf.org/public/rfc before calling kramdown-rfc2629)

Grüße, Carsten

I pushed a 1.0.34 with a workaround installed. Please update:

gem update

[cabo]

Leaving this open, as the workaround still needs to be moved to the proper stable base URI.

[jaimejim]

I can confirm that gem update to kramdown-rfc2629-1.0.34.gem fixes the bug for me.

[boutil]

I tried 1.0.36, and the problem is fixed for me too. Thanks!

[josephlhall]

Heya, after updating to a newer kramdown-rfc2629 I get a message "Occasionally run certified-update" but I had to hunt around to figure out that was the executable provided by the following gem: https://github.com/stevegraham/certified

Would be good to make that a bit easier to figure out.
