Resolution: Fixed
> Reservations which alter default imagemeta values may affect other

> Key: VCL-573
> URL: https://issues.apache.org/jira/browse/VCL-573
> Project: VCL
> Issue Type: Bug
> Components: vcld (backend)
> Affects Versions: 2.2.1
> Reporter: Andy Kurth
> Assignee: Andy Kurth
> Fix For: 2.3
>
>
> There is a bug involving the hash reference containing the default imagemeta
> values. utils.pm::get_default_imagemeta_info will retrieve the default
> values from the database and then save a cached copy in
> $ENV{imagemeta_info}{default}. This cached hash reference is returned for
> subsequent calls to get_default_imagemeta_info. This data is retrieved
> before vcld forks a process for each reservation. As a result, multiple
> reservation processes share the same hash reference. If one process changes
> anything in this hash, it affects other processes.
> This is occurring with the checkuser value. This value is being changed to 0
> for server requests. Once changed by one reservation, all subsequent
> reservations which use the default imagemeta data have the value set to 0.
> The code must be updated so that reservations can't affect each other.
