Subject: bug#30738: Invalid timezone (tzalloc failure) treated as out-of-memory
Date: Wed, 7 Mar 2018 01:53:46 +0300 [thread overview]
Message-ID: <20180306225346.GA22072@pony.stderr.spb.ru> (raw)
Emacs 25 treats tzalloc(3) failure as out-of-memory condition.
E.g. when an invalid timezone is specified, it fails to start with:
$ TZ=FOOBAR emacs -nw
emacs: Memory exhausted--use M-x save-some-buffers then exit and restart Emacs
The code in tzlookup() also assumes that tzalloc(3) understands the
direct zone specification in the name/offset format. I haven't
checked tzcode history, but this support is only a few years old
(around 2014, I'd estimate). E.g. NetBSD-6 has older tzcode(3) that
doesn't support this feature. This leads to a lot of "Memory
exhausted" errors when trying to use e.g. vc.el
"encode-time" (0xffffa2d4)
"apply" (0xffffa3fc)
"vc-cvs-parse-entry" (0xffffa718)
