Bug#1094270: std::filesystem::weakly_canonical throws if the file disappears during its execution
Package: libstdc++-14-dev
Version: 14.2.0-12
Severity: normal
Hello,
thank you for maintaining libstdc++.
The function std::filesystem::weakly_canonical is defined as working
even if the path points to a file that does not exist.
If however the path disappears while weakly_canonical does its thing, we
surprisingly get an exception.
I'm attaching a reproducer:
$ g++ weakly_canonical.cc -o weakly_canonical
$ ./weakly_canonical
Canonicalized path for missing file: "…/tmp/does-not-exist"
weakly_canonical failed at iteration 36: filesystem error: cannot make
canonical path: No such file or directory [tmp/test]
