| # Functions for use by content handlers: |
=pod |
| # |
|
| # metadata_query(sql-query-string,custom-metadata-regex) : |
=head1 NAME |
| # returns file handle of where sql and |
|
| # regex results will be stored for query |
Apache::lonnet.pm |
| # plaintext(short) : plain text explanation of short term |
|
| # fileembstyle(ext) : embed style in page for file extension |
=head1 SYNOPSIS |
| # filedescription(ext) : descriptor text for file extension |
|
| # allowed(short,url) : returns codes for allowed actions |
This file is an interface to the lonc processes of |
| # F: full access |
the LON-CAPA network as well as set of elaborated functions for handling information |
| # U,I,K: authentication modes (cxx only) |
necessary for navigating through a given cluster of LON-CAPA machines within a |
| # '': forbidden |
domain. There are over 40 specialized functions in this module which handle the |
| # 1: user needs to choose course |
reading and transmission of metadata, user information (ids, names, environments, roles, |
| # 2: browse allowed |
logs), file information (storage, reading, directories, extensions, replication, embedded |
| # definerole(rolename,sys,dom,cou) : define a custom role rolename |
styles and descriptors), educational resources (course descriptions, section names and |
| # set privileges in format of lonTabs/roles.tab for |
numbers), url hashing (to assign roles on a url basis), and translating abbreviated symbols to |
| # system, domain and course level, |
and from more descriptive phrases or explanations. |
| # assignrole(udom,uname,url,role,end,start) : give a role to a user for the |
|
| # level given by url. Optional start and end dates |
This is part of the LearningOnline Network with CAPA project |
| # (leave empty string or zero for "no date") |
described at http://www.lon-capa.org. |
| # assigncustomrole (udom,uname,url,rdom,rnam,rolename,end,start) : give a |
|
| # custom role to a user for the level given by url. |
=head1 Package Variables |
| # Specify name and domain of role author, and role name |
|
| # revokerole (udom,uname,url,role) : Revoke a role for url |
These are largely undocumented, so if you decipher one please note it here. |
| # revokecustomrole (udom,uname,url,rdom,rnam,rolename) : Revoke a custom role |
|
| # appenv(hash) : adds hash to session environment |
=over 4 |
| # delenv(varname) : deletes all environment entries starting with varname |
|
| # store(hashref,symb,courseid,udom,uname) |
=item $processmarker |
| # : stores hash permanently for this url |
|
| # hashref needs to be given, and should be a \%hashname |
Contains the time this process was started and this servers host id. |
| # the remaining args aren't required and if they aren't |
|
| # passed or are '' they will be derived from the ENV |
=item $dumpcount |
| # cstore(hashref,symb,courseid,udom,uname) |
|
| # : same as store but uses the critical interface to |
Counts the number of times a message log flush has been attempted (regardless |
| # guarentee a store |
of success) by this process. Used as part of the filename when messages are |
| # restore(symb,courseid,udom,uname) |
delayed. |
| # : returns hash for this symb, all args are optional |
|
| # if they aren't given they will be derived from the |
=back |
| # current enviroment |
|
| # |
=cut |
| # |
|
| # for the next 6 functions udom and uname are optional |
|
| # if supplied they use udom as the domain and uname |
|
| # as the username for the function (supply a courseid |
|
| # for the uname if you want a course database) |
|
| # if not supplied it uses %ENV and looks at |
|
| # user. attribute for the values |
|
| # |
|
| # eget(namesp,arrayref,udom,uname) |
|
| # : returns hash with keys from array reference filled |
|
| # in from namesp (encrypts the return communication) |
|
| # get(namesp,arrayref,udom,uname) |
|
| # : returns hash with keys from array reference filled |
|
| # in from namesp |
|
| # dump(namesp,udom,uname) : dumps the complete namespace into a hash |
|
| # del(namesp,array,udom,uname) : deletes keys out of array from namesp |
|
| # put(namesp,hash,udom,uname) : stores hash in namesp |
|
| # cput(namesp,hash,udom,uname) : critical put |
|
| # |
|
| # |
|
| # ssi(url,hash) : does a complete request cycle on url to localhost, posts |
|
| # hash |
|
| # coursedescription(id) : returns and caches course description for id |
|
| # repcopy(filename) : replicate file |
|
| # dirlist(url) : gets a directory listing |
|
| # directcondval(index) : reading condition value of single condition from |
|
| # state string |
|
| # condval(index) : value of condition index based on state |
|
| # EXT(name) : value of a variable |
|
| # symblist(map,hash) : Updates symbolic storage links |
|
| # symbread([filename]) : returns the data handle (filename optional) |
|
| # rndseed([symb,courseid,domain,uname]) |
|
| # : returns a random seed, all arguments are optional, |
|
| # if they aren't sent it use the environment to derive |
|
| # them |
|
| # Note: if symb isn't sent and it can't get one from |
|
| # &symbread it will use the current time as it's return |
|
| # receipt() : returns a receipt to be given out to users |
|
| # getfile(filename) : returns the contents of filename, or a -1 if it can't |
|
| # be found, replicates and subscribes to the file |
|
| # filelocation(dir,file) : returns a fairly clean absolute reference to file |
|
| # from the directory dir |
|
| # hreflocation(dir,file) : same as filelocation, but for hrefs |
|
| # log(domain,user,home,msg) : write to permanent log for user |
|

|
| |
=head1 OVERVIEW |
| |
|
| |
lonnet provides subroutines which interact with the |
| |
lonc/lond (TCP) network layer of LON-CAPA. They can be used to ask |
| |
about classes, users, and resources. |
| |
|
| |
For many of these objects you can also use this to store data about |
| |
them or modify them in various ways. |
| |
|
| |
=head2 Symbs |
| |
|
| |
To identify a specific instance of a resource, LON-CAPA uses symbols |
| |
or "symbs"X<symb>. These identifiers are built from the URL of the |
| |
map, the resource number of the resource in the map, and the URL of |
| |
the resource itself. The latter is somewhat redundant, but might help |
| |
if maps change. |
| |
|
| |
An example is |
| |
|
| |
msu/korte/parts/part1.sequence___19___msu/korte/tests/part12.problem |
| |
|
| |
The respective map entry is |
| |
|
| |
<resource id="19" src="/res/msu/korte/tests/part12.problem" |
| |
title="Problem 2"> |
| |
</resource> |
| |
|
| |
Symbs are used by the random number generator, as well as to store and |
| |
restore data specific to a certain instance of for example a problem. |
| |
|
| |
=head2 Storing And Retrieving Data |
| |
|
| |
X<store()>X<cstore()>X<restore()>Three of the most important functions |
| |
in C<lonnet.pm> are C<&Apache::lonnet::cstore()>, |
| |
C<&Apache::lonnet:restore()>, and C<&Apache::lonnet::store()>, which |
| |
is is the non-critical message twin of cstore. These functions are for |
| |
handlers to store a perl hash to a user's permanent data space in an |
| |
easy manner, and to retrieve it again on another call. It is expected |
| |
that a handler would use this once at the beginning to retrieve data, |
| |
and then again once at the end to send only the new data back. |
| |
|
| |
The data is stored in the user's data directory on the user's |
| |
homeserver under the ID of the course. |
| |
|
| |
The hash that is returned by restore will have all of the previous |
| |
value for all of the elements of the hash. |
| |
|
| |
Example: |
| |
|
| |
#creating a hash |
| |
my %hash; |
| |
$hash{'foo'}='bar'; |
| |
|
| |
#storing it |
| |
&Apache::lonnet::cstore(\%hash); |
| |
|
| |
#changing a value |
| |
$hash{'foo'}='notbar'; |
| |
|
| |
#adding a new value |
| |
$hash{'bar'}='foo'; |
| |
&Apache::lonnet::cstore(\%hash); |
| |
|
| |
#retrieving the hash |
| |
my %history=&Apache::lonnet::restore(); |
| |
|
| |
#print the hash |
| |
foreach my $key (sort(keys(%history))) { |
| |
print("\%history{$key} = $history{$key}"); |
| |
} |
| |
|
| |
Will print out: |
| |
|
| |
%history{1:foo} = bar |
| |
%history{1:keys} = foo:timestamp |
| |
%history{1:timestamp} = 990455579 |
| |
%history{2:bar} = foo |
| |
%history{2:foo} = notbar |
| |
%history{2:keys} = foo:bar:timestamp |
| |
%history{2:timestamp} = 990455580 |
| |
%history{bar} = foo |
| |
%history{foo} = notbar |
| |
%history{timestamp} = 990455580 |
| |
%history{version} = 2 |
| |
|
| |
Note that the special hash entries C<keys>, C<version> and |
| |
C<timestamp> were added to the hash. C<version> will be equal to the |
| |
total number of versions of the data that have been stored. The |
| |
C<timestamp> attribute will be the UNIX time the hash was |
| |
stored. C<keys> is available in every historical section to list which |
| |
keys were added or changed at a specific historical revision of a |
| |
hash. |
| |
|
| |
B<Warning>: do not store the hash that restore returns directly. This |
| |
will cause a mess since it will restore the historical keys as if the |
| |
were new keys. I.E. 1:foo will become 1:1:foo etc. |
| |
|
| |
Calling convention: |
| |
|
| |
my %record=&Apache::lonnet::restore($symb,$courseid,$domain,$uname); |
| |
&Apache::lonnet::cstore(\%newrecord,$symb,$courseid,$domain,$uname); |
| |
|

key -> path to file/file_name\0uniqueID:scope_end_start |
| |
where scope -> public,guest,course,group,domains or users. |
| |
end -> UNIX time for end of access (0 -> no end date) |
| |
start -> UNIX time for start of access |
| |
|
| |
value -> XML description of access control |
| |

Access data is also aggregated for each file in an additional key=value pair: |
| |
key -> path to file/file_name\0accesscontrol |
| |
value -> reference to hash |
| |
hash contains key = value pairs |
| |
where key = uniqueID:scope_end_start |
| |
value = UNIX time record was last updated |
| |
|
| |
Used to improve speed of look-ups of access controls for each file. |
| |
|
| |
Locks on files (resulting from submission of portfolio file to a homework problem stored in array of arrays. |

modify_access_controls(): |
| |
|
| |
Modifies access controls for a portfolio file |
| |
Args |
| |
1. file name |
| |
2. reference to hash of required changes, |
| |
3. domain |
| |
4. username |
| |
where domain,username are the domain of the portfolio owner |
| |
(either a user or a course) |
| |
|
| |
Returns: |
| |
1. result of additions or updates ('ok' or 'error', with error message). |
| |
2. result of deletions ('ok' or 'error', with error message). |
| |
3. reference to hash of any new or updated access controls. |

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. |
