Message #26 received at 50346 <at> debbugs.gnu.org (full text, mbox):

From: Simon South <simon <at> simonsouth.net>
To: 50346 <at> debbugs.gnu.org
Subject: [PATCH core-updates-frozen] gnu: strace: Allow readlink,
 readlinkat tests to pass.
Date: Sat,  4 Sep 2021 15:58:21 -0400

Modify the invocation of strace's "readlink" and "readlinkat" tests to prevent
them from failing due to an additional system call made by Guix's patched
version of glibc.

* gnu/packages/linux.scm (strace)[source]: Add patch.
[arguments]<#:phases>: Do not disable the "readlink" test now that it can
succeed.
* gnu/packages/patches/strace-fix-readlink-readlinkat-tests.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.

+Prevent strace's "readlink" and "readlinkat" tests from failing due to the

+applied (introduced in commit 52564e9).
+
+These changes cause strace to report during these tests only system calls on
+files contained in the test directory, effectively filtering out the
+additional readlink/readlinkat call on "/proc/self/exe" and allowing the tests
+to complete as normal.
