I'm ready to make a new release, so here's a pre-release snapshot.
Please build and test wherever you can.

Thank you!

Here's the NEWS-to-be:

** Bug fixes

  When decompressing data in 'pack' format, gzip no longer mishandles
  leading zeros in the end-of-block code.  [bug introduced in gzip-1.6]

  When converting timestamps to gzip file format (32-bit unsigned) or
  to time_t format (system-dependent), gzip now ignores out-of-range
  values instead of shoehorning them into the destination format,
  sometimes with undefined behavior.  This affects timestamps before
  1970 and after 2106, and timestamps after 2038 on platforms with
  32-bit signed time_t.  [bug present since the beginning]

  Support for VMS and Amiga has been removed.  It was not working anyway,
  and it reportedly caused file name glitches on MS-Windowsish platforms.

And indeed gzip exits with code 0, not 2, for some of the values:

$ export TZ=UTC0
$ rm -f in in.gz; touch -t 190101010000 in; ../../gzip in; echo $?
0
$ rm -f in in.gz; touch -t 190101010000 in; ls -l --full-time in

I'm using touch 8.25. The file system is ext4.

make[4]: *** [test-suite.log] Error 1


The 'touch' program that rejects distant timestamps is:

$ touch --version
touch (GNU coreutils) 8.24.161-1204d
...

I think the problem is this comment:
# On platforms that fail to support timestamps within gzip's range,
# test that gzip warns when converting them from gzip format.

Gzip's behaviour depends on libc, and what the 'touch' program is doing
is a different thing. It's incorrect to assume that libc's behaviour and
touch's behaviour are consistent.

Perhaps we should also fix Bug#29006, assuming it's indeed a bug? I'm a 
bit short on time right now and do not have time to check; maybe tomorrow.

Thanks a lot. This appears to have afflicted a few other types of systems, too.

This test used `printf '\x1f\x1e...' >test.z` to create a test input,
but some versions of printf fail to handle hexadecimal escapes in the
format string. Here's the fix I've pushed:

This is due to a bug in the Linux kernel, when it emulates 32-bit Linux atop a 
64-bit kernel. See:

https://bugzilla.redhat.com/show_bug.cgi?id=1419736

I see that Assaf reported the same bug against gzip here:

https://bugs.gnu.org/25636#8

I don't see an easy way of working around the bug in gzip proper. It will become 
a bigger deal when the year 2038 rolls around....

I suppose we could skip the test when running in 32-bit mode atop Linux x86-64, 
though that sort of misses the point of doing the test.

The concept of "expected failure" fits here, I think. If the test suite would flag
this as an XFAIL rather than a FAIL, people would not report it.

AFAIU from the doc [1], the way to turn a FAIL into an XFAIL is to add something
like this in the Makefile.am:

  XFAIL_TESTS =
  if $host is x86_64-*-linux* and $HOST_CPU_C_ABI is i386
  XFAIL_TESTS += timestamp
  fi

Thanks to both of you.
FYI, the timestamp test also fails on e.g., the Solaris 5.11 i386 platform.

Instead of suppressing the test, how about if we tell builders not to build with 
-m32 on platforms supporting 64-bit time_t? That way, they won't run into a 
problem where gzip mishandles file timestamps due to OS screwups or 
errno==EOVERFLOW problems that cannot happen with 64-bit time_t. In the 
not-too-distant future we're going to have to insist on 64-bit time_t anyway, 
and in the meantime we can strongly suggest 64-bit time_t by installing the 
first attached patch to gzip (which I've done), by installing the attached 
proposed patch to Gnulib (which I have not done yet, pending your comments), and 
by syncing gzip to gnulib.

The testcase doesn't assume that. It merely assumes that standard utilities 
support a superset of the timestamps that libc supports. This should be a 
reasonable assumption for the -m32 case that you describe (and which I'm trying 
to discourage with the abovementioned patches).

The assumption would not be reasonable for platforms where standard utilities 
are worse than libc, but this should be uncommon. If it is a problem, perhaps we 
can get by, by simply telling users to ignore the tests in that case.

CC'ing to bug-gnulib since the 2nd patch is for Gnulib.

Two of the three we've already discussed. In the third one, apparently this sort 
of /bin/sh script:

#!/bin/sh
exec printf '%s\n' "a long string"

improperly exits with status 0 when standard output is /dev/full. It might be 
helpful to see what system calls the shell is executing, possibly in preparation 
for sending a bug report to the FreeBSD maintainers. However, this is low 
priority, as we're talking only about incorrect exit status when zmore's 
diagnostics are discarded.

I'm having a bit of trouble figuring out what happened. Perhaps put "set -x" 
into the script, so that we can get a trace?

On second thought, never mind, this is probably the printf issue that 
Jim already fixed:

No further comment, and it seems like a good idea regardless of the test failure 
since the year 2038 will arrive sooner than we'd like, so I installed the patch 
into Gnulib and synced it into gzip.

In the newest gzip git, the 'unpack-valid' test now succeeds on
FreeBSD 11/x86 (32-bit), as well as on all other platforms that I have tested.
Probably due to Jim's 2 fixes.

As reported in https://lists.gnu.org/archive/html/bug-gzip/2017-11/msg00014.html
this change indeed fixes the failure on Hurd/i386.
