enum_default test fails on ppc64 #3714

Open thesamesam opened 2 years ago

Originally reported downstream in Gentoo. Please let me know if I can provide some more useful information!

From 3.0.13 (but it's the same with 3.0.16):

That's weird... and I have no immediate insight as to why that might be happening in an architecture-specific manner.

I'm not real familiar with Gentoo -- does Gentoo packaging include its own patches? If so are they viewable anywhere? Does anything change if you build directly from one of our release tarballs? (Please use a "cyrus-imapd-x.y.z.tar.gz" file, not the "Source code" files that github provides automatically.)

Do you have hardware you can re-run this on to collect some deeper diagnostics, or are you just passing on the report from downstream?

That's weird... and I have no immediate insight as to why that might be happening in an architecture-specific manner.

Especially since broadly the same configure options should be used on other architectures (see below). The exceptions would be for where certain dependencies for optional features may not be available on a certain architecture where we might disable it. I'll look for the difference between a machine which passes (amd64) and this one now.

Okay, so I tried building outside and it passed! But I wasn't using the same ./configure options as the Gentoo packaging (ebuilds). You can see our current packaging here (no patches applied atm).

When I do use the same, it fails outside (built manually):

./configure --prefix=/usr --build=powerpc64-unknown-linux-gnu --host=powerpc64-unknown-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/cyrus-imapd-3.4.2-r1  --htmldir=/usr/share/doc/cyrus-imapd-3.4.2-r1/html --with-sysroot=/ --libdir=/usr/lib64 --enable-murder --enable-idled --enable-autocreate --enable-pcre --with-com_err --with-cyrus-user=cyrus --with-sasl --with-sphinx-build=no --without-krb --without-krbdes --enable-squat --with-zlib --disable-afs --disable-krb5afspts --disable-backup --disable-calalarmd --without-libcap --without-clamav --disable-nntp --disable-http --without-nghttp2 --disable-replication  --disable-gssapi --without-ldap --without-mysql --without-pgsql --without-perl --without-sqlite --with-openssl --enable-server --disable-sieve --disable-static --with-libwrap --disable-xapian --enable-unit-tests

I've not yet narrowed down to what though. Will try...

This is good though in that it would rule out weird sandbox issues.

Do you have hardware you can re-run this on to collect some deeper diagnostics, or are you just passing on the report from downstream?

I do! I've managed to reproduce this myself and am happy to run and try debug as much as possible with guidance, but if it comes to it, I should be able to arrange for access if it's needed.

EDIT:

Good on amd64:

./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/cyrus-imapd-3.4.2-r1 --htmldir=/usr/share/doc/cyrus-imapd-3.4.2-r1/html --with-sysroot=/ --libdir=/usr/lib64 --enable-murder --enable-idled --enable-autocreate --enable-pcre --with-com_err --with-cyrus-user=cyrus --with-sasl --with-sphinx-build=no --without-krb --without-krbdes --enable-squat --with-zlib --disable-afs --disable-krb5afspts --disable-backup --disable-calalarmd --with-libcap --without-clamav --disable-nntp --disable-http --without-nghttp2 --disable-replication --disable-gssapi --without-ldap --without-mysql --without-pgsql --without-perl --without-sqlite --with-openssl --enable-server --disable-sieve --disable-static --without-libwrap --disable-xapian --enable-unit-tests

Bad on ppc64:

./configure --prefix=/usr --build=powerpc64-unknown-linux-gnu --host=powerpc64-unknown-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/cyrus-imapd-3.4.2-r1  --htmldir=/usr/share/doc/cyrus-imapd-3.4.2-r1/html --with-sysroot=/ --libdir=/usr/lib64 --enable-murder --enable-idled --enable-autocreate --enable-pcre --with-com_err --with-cyrus-user=cyrus --with-sasl --with-sphinx-build=no --without-krb --without-krbdes --enable-squat --with-zlib --disable-afs --disable-krb5afspts --disable-backup --disable-calalarmd --without-libcap --without-clamav --disable-nntp --disable-http --without-nghttp2 --disable-replication  --disable-gssapi --without-ldap --without-mysql --without-pgsql --without-perl --without-sqlite --with-openssl --enable-server --disable-sieve --disable-static --with-libwrap --disable-xapian --enable-unit-tests

But using the 'good'-from-amd64 command line on ppc64 fails. If I copy/paste the amd64 one (including the incorrect --host and such), it surprisingly does pass, but I have no idea why. Probably just a distraction.

--without-perl is an interesting choice. What happens if you omit this (and let it find and use some system perl)? (Heads up: it'll also install some Cyrus:: perl modules, which is probably what the use of --without-perl was trying to avoid.)

We know --with-perl=/some/other/perl is weird/broken in various ways (#2887), so I wonder if --without-perl (aka --with-perl=no) is similarly affected.

Though it would be strange if this affects only one unit test... but this was already pretty strange, so I'm not ruling out things that seem unrelated

Are you fluent in gdb? There might be a few things interesting to look at while stepping through the failing test -- let me know your skill level, and I'll think about what I want to ask you to try!

For what it's worth, GitHub doesn't send a new email notification for comment edits, so if it makes no difference to you, I'd prefer if you added new information by just adding a new comment. There's no stigma against double posting here. :)

For whatever it's worth, looks like Debian's ppc64 build works okay: https://buildd.debian.org/status/fetch.php?pkg=cyrus-imapd&arch=ppc64&ver=3.4.2-2&stamp=1631513029&raw=0

I thought it might be some endianness thing we'd missed, but if that were the case I'd expect it to fail for Debian too.

I've just tried building locally with --without-perl and it worked fine for me, but that's unsurprising since I'm also on amd64, where it also worked for you.

Let me try that. It looks like we provide it optionally ("USE flags") but that flag is off by default for our cyrus-imapd package.

I'm not a ninja but I should be able to poke well enough given a few hints. I'd say suggest what you want, and if it's too hard, I'll let you know?

Got it, thank you! I'll do that :)

I thought it might be some endianness thing we'd missed, but if that were the case I'd expect it to fail for Debian too.

Interestingly, it seems to pass on my little-endian ppc64 machine (it should be as identical as possible to the big-endian environment).

thesamesam commented 2 years ago

OK, fails with Perl too.

dilyanpalauzov commented 2 years ago

--enable-pcre used in the past to lead to failing tests. In the 'good' command line, pcre is not used. You can grep the archives on ‘pcre’ to find more.

elliefm commented 2 years ago

It's present in both...

But, PCRE is known to be a nuisance. Debian patches it, but I don't know if Gentoo does. And maybe there's an endianness problem or platform-specific quirk.

Very interested to hear what results you get from removing --enable-pcre, on both good- and bad- systems. Or you might need to --disable-pcre, I don't remember whether it will be automatically used if it's found installed...
