Hi,

The gcli package has a testsuite with post-2038 dates, which fail on Hurd.

We explicitly set -D_TIME_BITS=64 in CFLAGS, which solves the problem
everywhere else (even i386), but on Hurd, this is silently ignored.

In /usr/include/features-time64.h there is only a comment that it is
unsupported, not even a warning.

Hello,

Ah, indeed, that's the generic version.  We'd need to at least support
the redirection way, indeed.

reassign 1145140 libc0.3-dev
thanks

Hi,

The Hurd's libc SOVERSION is 0.3, so reassigning to the (hopefully)
correct package.

I have looked at the uses of time_t in the hurd part of glibc:

- We'd need a stat64_time64 variant of stat64.
- We'd need a 64b variant of msqid_ds.
- We'd need a 64b variant of shmid_ds.
- We'd need _time64 variants of various functions, probably something like:

Not sure it's worth the hassle for i386, while for other 32bit archs we
could define time_t as 64b already.

Samuel Thibault, le dim. 23 août 2026 11:53:34 +0200, a ecrit:

But it's actually a lot of work (introducing compatibility stat64_time64
and timespec64 structures, adding about a 100 compatibility functions)
only for the hurd-i386 port which is probably going to fade out exactly
like the i386 port anyway.

I have thus rather added a compilation warning on hurd-i386.

Samuel

I think we expect the i386 port to live on, however with broken
time_t values. For hurd-i386 IIRC it was said that the port will
cease before 2038, so it doesn't need this support?

Best,
Chris

Chris Hofstaedtler, le mar. 25 août 2026 21:41:06 +0200, a ecrit:

Will it really live, with completely broken time, beyond 2038?

That's the idea, yes.

Samuel

Hi,

26 Aug 2026 04:41:06 Chris Hofstaedtler <zeha@debian.org>:

i386 has working 64-bit time_t if a program asks for it, though, and
gcli's post-2038 tests pass there.

Also, it seems hurd-amd64 has the same issue (although that's unverified,
there doesn't appear to be a hurd-amd64 porterbox).

Simon Richter, le mer. 26 août 2026 10:54:01 +0900, a ecrit:

Yes, because a lot of effort was spent to get it.

No, the buildd log says otherwise.

Samuel

That is the current project position, as far as I know.

Personally I think when 2038 comes closer or has passed, it will
become more clear what will happen.

Chris

We believe that the bug you reported is fixed in the latest version of
glibc, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1145140@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
