[Live System User]

Hi,

        I am getting an "Invalid date" error when starting
        Gnus (see attachment).

        I don't get this error and Gnus starts up normally
        with Emacs 26.1.

        Thanks.

More information was requested some weeks back, but no response was
given, so I'm closing this bug report.  If you're still seeing this
problem, please reopen.

bug#32443: 27.0.50; encode-time bug

[Live System User]

Hi,

        A closer look seems to show this bug is rooted in
        a regression in (ultimately) 'parse-time-string':

           M-: (date-to-time "Tue, 06 Mar 2018 11:17:02 -0500")
           Invalid date: Tue, 06 Mar 2018 11:17:02 -0500

        When the date/time is being parsed, you erroneously get:

           M-: (parse-time-string "Tue, 06 Mar 2018 11:17:02 -0500")
           (nil nil nil 6 3 2018 2 nil nil)

        With Emacs 26.1, you get:

           (2 17 11 6 3 2018 2 nil -18000)

        Thanks.

I can't reproduce this.

I see that distribution is EOL for one year now.
(And Fedora 25 and 26 are EOL too.)

Iʼve seen this, but only once with a time string of "Tue, 28 Aug 2018 13:16:54
+0200". Iʼve not been able to reproduce in 'emacs -Q'.

  I get the same erroreous output with "emacs -Q" with your date
  as well:


(parse-time-string "Tue, 14 Aug 2018 09:14:11 +0400")
(nil nil nil 14 8 2018 2 nil nil)


(parse-time-string "Tue, 28 Aug 2018 13:16:54 +0200")
(nil nil nil 28 8 2018 2 nil nil)

(parse-time-string "Wed, 29 Aug 2018 11:15:22 -0400")
(nil nil nil 29 8 2018 3 nil nil)



  Thanks.

None of those fail for me. Could you tell us which revision youʼre
currently using? Perhaps this got fixed as a side effect of some other
change, in which case I can bisect it.

Otherwise, since youʼre the only one who can reproduce it, could you
do 'edebug-defun' on 'parse-time-string' and step through it? That
might give us a better idea of what's going wrong.

Thanks

Robert

  I just tried it using:

Repository revision: d8bef4b519624de20baa1428dd103f61dfb220fa

   and got the same errpneous results.

  I've never used `edebug' before so I will have to get up to speed.

And thatʼs more recent than my version, so the bug is still lurking
somewhere.

SPC single steps. You can use 'e' to evaluate arbitrary expressions in
the context of the function youʼre debugging. Since single stepping
can be tedious, you can move point and use 'h' to run until you reach
point.

  I'm still trying to discover where the bug is using edebug,

  Stepping through with edebug everything appears to go fine
  with going through all the rules and assigning all of its
  resultant values (such as "Tue' equals 2 gleen from
  `parse-time-weekdays '), until you get to the following:

        (rplaca (nthcdr (pop slots) time) new-val))))))))


  Once I execute `rplaca' -- "tike" and "new-val" are incorrect.
  
 FWIW, with thw recwnt update to parse-time.el (Git 0bec064), I now
 get

(parse-time-string "Tue, 21 Feb 2017 17:17:56 -0500")
 (nil nil nil 21 2 2017 2 -1 nil)


`Before this update, the "-1" was nil.

 I believe the "-1" means that DST is not known to be in effect.

 DST *is* in effect here.

`Thanks.
