$priv is the privilege being checked. |

$uri contains additional information about what is being checked for access (e.g., |

$symb is the unique resource instance identifier in a course; if needed, |

but not provided, it will be retrieved via a call to &symbread(). |
|
$role is the role for which a priv is being checked (only used if priv is evb). |
|
$clientip is the user's IP address (only used when checking for access to portfolio |

$noblockcheck, if true, skips calls to &has_comm_blocking() for the bre priv. This |

users' roles.db to check for a dc or su role in any domain. This can be |
|
time consuming if &privileged is called repeatedly (e.g., when displaying a |
|
classlist), so in such cases, supplying a $possdomains array is preferred, as |

this then allows &privileged_by_domain() to be used, which caches the identity |

of privileged users, eliminating the need for repeated calls to &dump(). |

for active or future "privileged" users with that role in that domain. To avoid |

repeated dumps of domain roles -- via &get_domain_roles() -- contents of the |

In cases where a domain coordinator has never used the "Set Domain Configuration" |
|
utility to create a configuration.db file on a domain's primary library server |
|
only the following domain defaults: auth_def, auth_arg_def, lang_def |
|
-- corresponding values are authentication type (internal, krb4, krb5, |
|
or localauth), initial password or a kerberos realm, language (e.g., en-us) -- |
|
will be available. Values are retrieved from cache (if current), unless the |
|
optional $ignore_cache arg is true, or from domain's configuration.db (if available), |
|
or lastly from values in lonTabs/dns_domain,tab, or lonTabs/domain.tab. |
|
|
|
Typical usage: |
|
|
|
%domdefaults = &get_domain_defaults($target_domain); |

get_timebased_id(): |
|
|
|
Attempts to get a unique timestamp-based suffix for use with items added to a |
|
course via the Course Editor (e.g., folders, composite pages, |
|
group bulletin boards). |
|
|
|
Args: (first three required; six others optional) |
|
|
|
1. prefix (alphanumeric): of keys in hash, e.g., suppsequence, docspage, |
|
docssequence, or name of group |
|
|
|
2. keyid (alphanumeric): name of temporary locking key in hash, |
|
e.g., num, boardids |
|
|
|
3. namespace: name of gdbm file used to store suffixes already assigned; |
|
file will be named nohist_namespace.db |
|
|
|
4. cdom: domain of course; default is current course domain from %env |
|
|
|
5. cnum: course number; default is current course number from %env |
|
|
|
6. idtype: set to concat if an additional digit is to be appended to the |
|
unix timestamp to form the suffix, if the plain timestamp is already |
|
in use. Default is to not do this, but simply increment the unix |
|
timestamp by 1 until a unique key is obtained. |
|
|
|
7. who: holder of locking key; defaults to user:domain for user. |
|
|
|
8. locktries: number of attempts to obtain a lock (sleep of 1s before |
|
retrying); default is 3. |
|
|
|
9. maxtries: number of attempts to obtain a unique suffix; default is 20. |
|
|
|
Returns: |
|
|
|
1. suffix obtained (numeric) |
|
|
|
2. result of deleting locking key (ok if deleted, or lock never obtained) |
|
|
|
3. error: contains (localized) error message if an error occurred. |
