Amaya/PICS

Amaya/PICS Technical Details

The following changes were made to the source code of the standard Amaya distribution:

C

/amaya/EDITORActions.c

new procedures:
RootCall -- Called when the Rootmode button of the UI is clicked.
UserCall -- Called when the Usermode button of the UI is clicked.
GetRoot -- When called, will return a structure containing the encrypted root password, and the cryptographic salt used by the system, both of which are read out of /etc/passwd

/amaya/javaamaya.c

new procedures:
PopUpPICSDialog -- Displays a dialog box that asks for the root password.
GetRootMode -- Checks whether Amaya is in root mode or user mode.
SetRootMode -- Puts Amaya into either root mode or user mode.

/amaya/init.c

Existing procedures were modified to support the two new buttons on the button bar, and to support the new dialog type for PopUpPICSDialog

/amaya/R.xpm
/amaya/U.xpm

The two new icons for the two new buttons on the button bar.

Java

/classes/w3c/amaya/APIJavaAmaya.java

Contains the Java native declarations for the new procedures in javaamaya.c listed above.

/classes/w3c/amaya/HTTPRequest.java

new procedures:
invalidUser -- Produces an error page when the user enters an incorrect password, when attempted to change a profile.
HostileMode -- Produces error pages for other error-causing conditions, such as a modified .thotrc file. (See the user documentation of Amaya/PICS for details on the error conditions).

changes:
The Get method was changed significantly to support filters. See the user documentation for details of how filters behave.

New package:
The PICS Standard library has been included (package w3c.pics.parser). It performs all the profile and label parsing, and all filter evaluation. It has its own documentation online.
