Bug ID: 1650041
Summary: Perl 5.28.0 in-place edit broken
Product: Fedora
Version: 29
Component: perl
Severity: high
Assignee: jples...@redhat.com
Reporter: m.schwa...@javatrend.de
QA Contact: extras...@fedoraproject.org
CC: caillon+fedoraproj...@gmail.com, iarn...@gmail.com,

Description of problem:
It seems the inplace edit is broken in perl 5.28.0: in some circumstances the
file is not updated with the output from STDOUT. In the example below the -i
script reads the complete input and then writes the output. This works for all
perl versions I have tested so far, but not with 5.28.0
Version-Release number of selected component (if applicable):
5.28.0
How reproducible:
The problem can be easily reproduced, find below a short test script.
Steps to Reproduce:
$ perl -e 'print "Perl $^V: FAILED\n"' > testfile
$ perl -i -e 'local $/; my $s=<>; $s=~s/FAILED/OK/; print $s;' testfile
$ cat testfile
Actual results:
Perl v5.28.0: FAILED
Expected results:
Perl v5.28.0: OK
Additional info:
I have tested with a few older versions, which deliver the expected output:
Perl v5.26.1: OK
Perl v5.24.1: OK
Perl v5.16.3: OK
Per: OK # v5.8.8 without $^V
