Und anderem Code-Schnipsel (irrelevant Codes weggelassen) unten ist für Parameter-Analyse:
our $file_name = $cgi->param('f');
our $hash = $cgi->param('h');
our $hash_parent = $cgi->param('hp');
our $hash_base = $cgi->param('hb');
our $hash_parent_base = $cgi->param('hpb');
Deshalb ist die folgende falsch:
defined $hash_base
Leider sind das alles, was ich habe.
Von diesen Codes wird die Ausnahme nicht erwartet.
Allerdings ist Ihr Gitweb möglicherweise nicht das neueste. Ich schlage vor, Sie überprüfen Ihre Quellen.
@student Sie könnten gitweb aktualisieren, um zu sehen, ob das Problem weiterhin besteht –
