Avoid errors from selecting "no selection" on multilink (issue2550722).
As discussed in issue 2550722 there are various cases where selecting
"no selection" on a multilink can result in inappropriate errors from
Roundup:
* If selecting "no selection" produces a null edit (a value was set in
the multilink in an edit with an error, then removed again, along
with all other changes, in the next form submission), so the page is
rendered from the form contents including the "-<id>" value for "no
selection" for the multilink.
* If creating an item with a nonempty value for a multilink has an
error, and the resubmission changes that multilink to "no selection"
(and this in turn has subcases, according to whether the creation
then succeeds or fails on the resubmission, which need fixes in
different places in the Roundup code).
All of these cases have in common that it is expected and OK to have a
"-<id>" value for a submission for a multilink when <id> is not set in
that multilink in the database (because the original attempt to set
<id> in that multilink had an error), so the hyperdb.py logic to give
an error in that case is thus removed. In the subcase of the second
case where the resubmission with "no selection" has an error, the
templating code tries to produce a menu entry for the "-<id>"
multilink value, which also results in an error, hence the
templating.py change to ignore such values in the list for a
multilink.

.TH ROUNDUP-SERVER 1 "27 July 2004" .SH NAME roundup-server \- start roundup web server .SH SYNOPSIS \fBroundup-server\fP [\fIoptions\fP] [\fBname=\fP\fItracker home\fP]* .SH OPTIONS .TP \fB-C\fP \fIfile\fP Use options read from the configuration file (see below). .TP \fB-n\fP \fIhostname\fP Sets the host name or IP address to listen on. Default is localhost (127.0.0.1). Use 0.0.0.0 to listen on all interfaces on the system. .TP \fB-p\fP \fIport\fP Sets the port to listen on (default: 8080). .TP \fB-d\fP \fIfile\fP Daemonize, and write the server's PID to the nominated file. .TP \fB-l\fP \fIfile\fP Sets a filename to log to (instead of stdout). This is required if the -d option is used. .TP \fB-i\fP \fIfile\fP Sets a filename to use as a template for generating the tracker index page. The variable "trackers" is available to the template and is a dict of all configured trackers. .TP \fB-s\fP Enables to use of SSL. .TP \fB-e\fP \fIfile\fP Sets a filename containing the PEM file to use for SSL. If left blank, a temporary self-signed certificate will be used. .TP \fB-N\fP Log client machine names instead of IP addresses (much slower). .TP \fB-u\fP \fIUID\fP Runs the Roundup web server as this UID. .TP \fB-g\fP \fIGID\fP Runs the Roundup web server as this GID. .TP \fB-d\fP \fIPIDfile\fP Run the server in the background and write the server's PID to the file indicated by PIDfile. The -l option \fBmust\fP be specified if -d is used. .TP \fB-v\fP Print version and exit. .TP \fB-h\fP Print help and exit. .TP \fBname=\fP\fItracker home\fP Sets the tracker home(s) to use. The \fBname\fP variable is how the tracker is identified in the URL (it's the first part of the URL path). The \fItracker home\fP variable is the directory that was identified when you did "roundup-admin init". You may specify any number of these name=home pairs on the command-line. For convenience, you may edit the TRACKER_HOMES variable in the roundup-server file instead. Make sure the name part doesn't include any url-unsafe characters like spaces, as these confuse the cookie handling in browsers like IE. .SH EXAMPLES .TP .B roundup-server -p 9000 bugs=/var/tracker reqs=/home/roundup/group1 Start the server on port \fB9000\fP serving two trackers; one under \fB/bugs\fP and one under \fB/reqs\fP. .SH CONFIGURATION FILE See the "admin_guide" in the Roundup "doc" directory. .SH AUTHOR This manpage was written by Bastian Kleineidam <calvin@debian.org> for the Debian distribution of roundup. The main author of roundup is Richard Jones <richard@users.sourceforge.net>.
