"{DIR}" caused some problems. - Changed the names of some error messages: nocopy -> no_copy noedit -> no_edit noview -> no_view --- diff --git a/devedit.pl b/devedit.pl index aa7a3ca..3ec92df 100644 --- a/devedit.pl +++ b/devedit.pl @@ -6,7 +6,7 @@ # Dev-Editor's main program # # Author: Patrick Canterino -# Last modified: 2004-11-13 +# Last modified: 2004-11-26 # use strict; @@ -82,6 +82,14 @@ if($newfile ne '' && $newfile !~ /^\s+$/) abort($config->{'errors'}->{'create_ar'},"/"); } + # Check if we have enough permissions to create a file + # in this directory + + unless(-r $new_physical && -w $new_physical && -x $new_physical) + { + abort($config->{'errors'}->{'dir_no_create'},"/",{DIR => $new_virtual}); + } + # Create the physical and the virtual path $new_physical = File::Spec->canonpath($new_physical."/".$file); diff --git a/errors.dat b/errors.dat index b09148f..995e5f8 100644 --- a/errors.dat +++ b/errors.dat @@ -7,6 +7,7 @@ copy_failed = Could not copy '{FILE}' to '{NEW_FILE}'. create_ar = You aren't allowed to create files and directories above the virtual root directory. delete_failed = Could not delete file '{FILE}'. dircopy = This editor is not able to copy directories. +dir_no_create = You have not enough permissions to create a file in the directory '{DIRECTORY}'. dir_not_exist = The directory where you want to create this file or directory doesn't exist. dir_read_fail = Reading of directory '{DIR}' failed. dir_replace = You are not allowed to replace a directory. @@ -21,14 +22,16 @@ invalid_group = '{GROUP}' seems to be an invalid group name.
