Description Jerry James 2025-01-30 23:31:17 UTC

Koschei reports that several packages I maintain have started failing to build in the last few days.  Each of these packages invokes which at some point during the build.  The latest version of which behaves oddly.  For example, the 4ti2 package has a subdirectory named doc.  During the build, the current directory is changed to doc, and the command `../src/zsolve/hilbert --help` is invoked to get the help text for the hilbert command.

The hilbert command is a script that starts with:

SCRIPT=`which "$0"`
SCRIPTDIR=`dirname "$SCRIPT"`

With which 2.21, the values were:

SCRIPT=/builddir/build/BUILD/4ti2-1.6.10-build/4ti2-1.6.10/doc/../src/zsolve/hilbert
SCRIPTDIR=/builddir/build/BUILD/4ti2-1.6.10-build/4ti2-1.6.10/doc/../src/zsolve

With which 2.22, they are instead:

SCRIPT=/builddir/build/BUILD/4ti2-1.6.10-build/4ti2-1.6.10/docsrc/zsolve/hilbert
SCRIPTDIR=/builddir/build/BUILD/4ti2-1.6.10-build/4ti2-1.6.10/docsrc/zsolve

That SCRIPTDIR doesn't exist, causing the build to fail.  What happened to the "/../" between "doc" and "src"?

Reproducible: Always

Steps to Reproduce:
1. fedpkg clone 4ti2
2. cd 4ti2
3. fedpkg srpm
4. mock -r fedora-rawhide-x86_64 --rebuild 4ti2-1.6.10-15.fc42.src.rpm
Actual Results:  
The build fails due to the which command returning a bogus value.

Expected Results:  
The which command should continue to return correct values, as it did in prior versions.
