Dear maintainer:

During a rebuild of all packages in bookworm, this package failed to build.

[ Note: The bug is marked as fixed with the version in trixie/forky/sid, but
  packages in bookworm must still build in bookworm ].

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/bookworm/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:crystal, so that this is still
visible in the BTS web page for this package.

Thanks.

notfixed 1137045 1.14.0+dfsg-1
thanks

Note: A similar failure happens when building the package in unstable
using the old schroot backend (which was the default in bookworm).

Given that this usually happens when the package attempts to use
Internet during build, which is considered RC, I'm marking
this bug as not really fixed in the unstable version.

Thanks.

retitle 1137045 crystal: Tries to access Internet during build
thanks

Hi. One of the tests tries to resolve "doesnotexist.example.org", which
is a DNS resolution and therefore does count as Internet access.

Thanks.

Hello. It seems that the package itself already has a framework to
skip network tests.

The attached patch works for me.

Try building the package with sbuild using the old schroot backend,
with and without the patch, to see the difference.

Thanks.

Hi,

I gave Santiago's patch a try on crystal 1.18.2+dfsg-1, and it works for
me.

I could not use schroot on this machine, so I tested it with sbuild's
unshare backend, with networking disabled. The full build completed
successfully:

  compiler_spec:   13306 examples, 0 failures, 0 errors, 18 pending
  std_spec:        17491 examples, 0 failures, 0 errors, 28 pending
  primitives_spec:   717 examples, 0 failures, 0 errors, 0 pending

For comparison, the unpatched std_spec ran 17563 examples, with 33
pending. The difference is exactly 72 examples and 5 pending examples,
matching all the examples tagged "network" in the five socket spec
files. The compiler and primitives counts did not change.

One slightly confusing detail is that the unpatched build also passed
with the unshare backend. This is because the resolver error from its
isolated network namespace is accepted by the current tests. To check
the actual network activity, I also ran those five socket spec files
under strace in a network-enabled environment. Without the filter,
strace recorded five connect(2) calls to DNS port 53 (15 system calls
involving port 53 in total). With "--tag '~network'", no examples were
selected and strace recorded no DNS or connect calls.

So the patch appears to do exactly what we want: it skips only the 72
network-tagged examples, and the rest of the test suite still passes.

As of today, crystal 1.18.2+dfsg-1 and its reverse dependency shards are
still scheduled for autoremoval from testing on 22 August because of
this bug. Could you please apply the patch and upload a fixed version
before then?
