Subject: 24.4;
 eww-mode error in process sentinel 'Invalid date' when receiving a
 valid date
Date: Fri, 06 Feb 2015 23:49:18 -0500

When running eww-mode and visiting a site using a cookie expiration date
set to "Mon, 06 Mar 2130 20:55:03 GMT" eww-mode will fail to load
subsequent URLs on the domain (in this case http://ahungry.com) and
instead simply print the following message in the echo area:

error in process sentinel: Invalid date: Mon, 06 Mar 2130 20:55:03 GMT

According to Wikipedia and other sources I can find online regarding the
HTTP cookie expires field, this date format is valid
(https://en.wikipedia.org/wiki/HTTP_cookie) and should not be causing 
an error in the process sentinel (and even if some site sent an invalid
date, I don't think it should halt further site interaction, but either
ignore the invalid date, or ignore the cookie).

Steps to reproduce under emacs -Q:

eww
ahungry.com
RET
TAB
TAB
RET

You'll then see the error pop up (instead of visiting the Blog link on
the site).

Is your Emacs a 32-bit executable?

[Message part 1 (text/plain, inline)]

It is and I did, but the emacs with the issue is not configured for gnus/mail yet so I was reporting from my 64bit emacs instead .  After seeing it includes by default a lot of personal information such as the last few things I typed and my home paths I just deleted the info it auto added as it was not relevant to the bug.

It seems to be a year 2038 bug in the encode - time function, but eww should gracefully handle vs just failing when it happens.

Can you get a Lisp backtrace as of when the error occurs?

The *Backtrace* buffer remains empty, but this is what gets printed to
*Messages* when you do the following:

1) M-x eww
2) ahungry.com
3) TAB TAB (you'll now be on Blog link)
4) RET
5) Failure to load next page

I reproduced this bug on Fedora 21 i686.  I looked at the current master and 
fixed some relevant issues, in commit fd6f7d1449c8496ab5c019d2aad7ca5e2980713a 
dated today.  I then attempted to reproduce the bug but failed, so it appears 
that the bug is fixed now in the current master (either by the recent fixes, or 
by earlier fixes in the master).  Please give it a try.

Thanks for checking, and so I'm closing Bug#19798 too.
