Dear all, I receive validation errors of my config file after changes to the (global) config in the web interface. Consequently, BackupPC terminates.
I'm absolutely sure that this worked before; my last (host) config change dates
back to Feb 2022, the last global config change happened mid 2020.
Unfortunately, I can't pinpoint a specific culprit (system) update anymore.
Normal operation is not affected, so I didn't spot the issue earlier; just
undoing the most recent perl-related updates from today's regular update does
not help.
The issue is that upon changing the main config or, e.g., adding a host, HASH
or ARRAY entries in the config file are written with parentheses rather than
braces or brackets, as expected. In turn, I receive
> Software error:
>
> Not an ARRAY reference at /usr/share/backuppc/lib/BackupPC/CGI/Lib.pm line
> 468.
or similar messages on operations that re-read the config, accompanied by
crashes of the server. Attached is a diff of the config folder, with entries
like
2431c2431
< $Conf{ClientShareName2Path} = {};
---
> $Conf{ClientShareName2Path} = ();
2433c2433
< $Conf{RsyncIncrArgsExtra} = [];
---
> $Conf{RsyncIncrArgsExtra} = ();
I can fix the config manually and the server starts again; however, I'm not
100% confident whether some log/configuration data is written periodically,
e.g. on nightlies, and more dragons hide behind the scenes.
Did anyone experience a similar problem? Any know incompatibilities with one of
the more recent perl packages? Any clues what might be the problem?
For context, I'm on Arch, pretty much up-to-date; relevant versions of
BackupPC, web server and dependencies are
backuppc 4.4.0-5
lighttpd 1.4.67-1
glibc 2.36-6
popt 1.18-3
perl 5.36.0-1
par2cmdline 0.8.1-2
perl-archive-zip 1.68-7
perl-io-dirent 0.05-15
perl-file-listing 6.15-2
perl-time-modules 2013.0912-8
perl-cgi 4.54-2
perl-xml-rss 1.62-1
perl-json-xs 4.03-3

Thanks and cheers,
