|
|
|
Collects lastname, generation, middlename, firstname, PID, and section for each |
|
student from their environment database. The section data is also download, though |
|
it is in a rough format, and is processed later. The list of students is built from |
|
collecting a classlist for the course that is to be displayed. Once the classlist |
|
has been downloaded, its date stamp is recorded. Unless the datestamp for the |
|
class database is reset or is modified, this data will not be downloaded again. |
|
Also, there was talk about putting the fullname and section |
|
and perhaps other pieces of data into the classlist file. This would |
|
reduce the number of different file accesses and reduce the amount of |
|
processing on this side. |

$c: The connection class that can determine if the browser has aborted. It |

is used to short circuit this function so that it does not continue to |

get information when there is no need. |

\%classlist: A pointer to a hash containing the following data: |

|
|
-A list of student name:domain (as keys) (known below as $name) |

-A hash pointer for each student containing lastname, generation, firstname, |

middlename, and PID : Key is $name.studentInformation |

-A hash pointer to each students section data : Key is $name.section |
|

-If there was an error in dump, it will be returned in the hash. See |

the error codes for dump in lonnet. Also, an error key will be |

generated if an abort occurs. |

HISTORY: This function originally existed in every statistics module, |
|
and performed different tasks, the had some overlap. Due to the need |
|
for the data from the different modules, they were combined into |
|
a single function. |
|
|
|
This function now extracts all the necessary course data for a student |
|
from what was downloaded from their homeserver. There is some extra |
|
time overhead compared to the ProcessStudentInformation function, but |
|
it would have had to occurred at some point anyways. This is now |
|
typically called while downloading the data it will process. It is |
|
the brother function to ProcessStudentInformation. |

Determine if the cache database can be accessed with a tie. It waits up to |

ten seconds before returning failure. This function exists to help with |

the problems with stopping the data download. When an abort occurs and the |

user quickly presses a form button and httpd child is created. This |

|
|
|
Does a lonnet::dump on a student to populate the courses tables. |
|
|
|
Input: $sname, $sdom, $courseid |
|
|
|
Output: $returnstatus |
|
|
|
$returnstatus is a string describing any errors that occured. 'okay' is the |
|
default. |
|
|
|
This subroutine loads a students data using lonnet::dump and inserts |
|
it into the MySQL database. The inserts are done on three tables, |
|
$fulldump_response_table, $fulldump_part_table, and $fulldump_timestamp_table. |
|
The INSERT calls are made directly by this subroutine, not through lonmysql |
|
because we do a 'bulk'insert which takes advantage of MySQLs non-SQL |
|
compliant INSERT command to insert multiple rows at a time. |
|
If anything has gone wrong during this process, $returnstatus is updated with |
|
a description of the error. |
|
|
|
Once the "fulldump" tables are updated, the tables used for chart and |
|
spreadsheet (which hold only the current state of the student on their |
|
homework, not historical data) are updated. If all updates have occured |
|
successfully, $student_table is updated to reflect the time of the update. |
|
|
|
Notice we do not insert the data and immediately query it. This means it |
|
is possible for there to be data returned this first time that is not |
|
available the second time. CYA. |
