Saving my work on Bug #4127 - still having problems with "Invalid access"

After recently changing resource version for a course, &symbverify fails
in spite of both the URL and the given symb being correct.

Not sure what else needs to be reset.

This is the 55: invocation by F<loncapa_apache.conf>: 56: 57: <Location /adm/publish> 58: PerlAccessHandler Apache::lonacc 59: SetHandler perl-script 60: PerlHandler Apache::lonpublisher 61: ErrorDocument 403 /adm/login 62: ErrorDocument 404 /adm/notfound.html 63: ErrorDocument 406 /adm/unauthorized.html 64: ErrorDocument 500 /adm/errorhandler 65: </Location> 66: 67: =head1 OVERVIEW 68: 69: Authors can only write-access the C</~authorname/> space. They can 70: copy resources into the resource area through the publication step, 71: and move them back through a recover step. Authors do not have direct 72: write-access to their resource space. 73: 74: During the publication step, several events will be 75: triggered. Metadata is gathered, where a wizard manages default 76: entries on a hierarchical per-directory base: The wizard imports the 77: metadata (including access privileges and royalty information) from 78: the most recent published resource in the current directory, and if 79: that is not available, from the next directory above, etc. The Network 80: keeps all previous versions of a resource and makes them available by 81: an explicit version number, which is inserted between the file name 82: and extension, for example C<foo.2.html>, while the most recent 83: version does not carry a version number (C<foo.html>). Servers 84: subscribing to a changed resource are notified that a new version is 85: available. 86: 87: =head1 DESCRIPTION 88: 89: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA 90: digital library. This includes updating the metadata table in the 91: LON-CAPA database. 92: 93: B<lonpublisher> is many things to many people. 94: 95: This module publishes a file. This involves gathering metadata, 96: versioning the file, copying file from construction space to 97: publication space, and copying metadata from construction space 98: to publication space. 99: 100: =head2 SUBROUTINES 101: 102: Many of the undocumented subroutines implement various magical 103: parsing shortcuts. 104: 105: =over 4 106: 107: =cut 108: 109: ###################################################################### 110: ###################################################################### 111: 112: 113: package Apache::lonpublisher; 114: 115: # ------------------------------------------------- modules used by this module 116: use strict; 117: use Apache::File; 118: use File::Copy; 119: use Apache::Constants qw(:common :http :methods); 120: use HTML::LCParser; 121: use Apache::lonxml; 122: use Apache::loncacc; 123: use DBI; 124: use Apache::lonnet; 125: use Apache::loncommon(); 126: use Apache::lonmysql; 127: use Apache::lonlocal; 128: use Apache::loncfile; 129: use LONCAPA::lonmetadata; 130: use Apache::lonmsg; 131: use vars qw(%metadatafields %metadatakeys); 132: 133: my %addid; 134: my %nokey; 135: 136: my $docroot; 137: 138: my $cuname; 139: my $cudom; 140: 141: my $registered_cleanup; 142: my $modified_urls; 143: 144: =pod 145: 146: =item B<metaeval> 147: 148: Evaluates a string that contains metadata.
