sl@0: // @SYMTestCaseID				KBASE-DP_FUNC_ATTRIBUTES-0303
sl@0: // @SYMTestCaseDesc			Symbian OS Toolchain's Paging Override and the
sl@0: // Paging Policy settings
sl@0: // @SYMREQ						REQ6808
sl@0: // @SYMPREQ					PREQ1110
sl@0: // @SYMTestPriority			High
sl@0: // @SYMTestActions
sl@0: // 1.	Load executables with the RProcess API and run them. Each executable has a
sl@0: // different set of attributes:
sl@0: // "	Paging attribute: paged, unpaged or no paging attribute in MMP and/or
sl@0: // OBY files
sl@0: // "	Compression mode: specified or not
sl@0: // "	Executable built in ROM as 'data' or 'file'
sl@0: // "	Solid binaries or aliases
sl@0: // Retrieve and analyse the demand paging activity trace caused by the preceding
sl@0: // action, in order to determine whether this binary is paged on demand or not.
sl@0: // 2.	Repeat the preceding action by loading DLLs with the RLibrary API and
sl@0: // making calls to them.
sl@0: // @SYMTestExpectedResults
sl@0: // 1.	Process complete without error. If, according to the trace data gathered,
sl@0: // the main thread newly created process causes the executable to be paged in,
sl@0: // then it is a proof that the executable is paged. Depending on the Paging
sl@0: // Override setting and the Loader Paging Policy specified at the time the ROM was
sl@0: // built, the Loader makes a decision as to whether page the binary or not,
sl@0: // according to the rules listed in the Design Sketch. This is how we determine
sl@0: // this, in this order:
sl@0: // a.	If ROM paging is disabled: not paged
sl@0: // b.	If executable was built in ROM as 'data': not paged
sl@0: // c.	If the a file compression scheme was specified at ROM build time: not paged
sl@0: // d.	If the Loader Paging policy is 'NOT PAGED': not paged
sl@0: // e.	If the Loader Paging policy is 'ALWAYS PAGE': paged
sl@0: // f.	If the Paging Override is 'NOT PAGED': not paged
sl@0: // g.	If the Paging Override is 'ALWAYS PAGE': paged
sl@0: // h.	If the OBY paging keyword for this executable is 'PAGED': paged
sl@0: // i.	If the OBY paging keyword for this executable is 'NOT PAGED': unpaged
sl@0: // j.	If the MMP paging keyword for this executable is 'PAGED': paged
sl@0: // k.	If the MMP paging keyword for this executable is 'NOT PAGED': not paged
sl@0: // l.	If the Paging Override is 'DEFAULT UNPAGED': not paged
sl@0: // m.	If the Paging Override is 'DEFAULT PAGED': paged
sl@0: // n.	If the Paging Policy is 'DEFAULT UNPAGED': not paged
sl@0: // o.	The executable must be paged
sl@0: // 2.	DLL is loaded. Functions are called and complete without errors. The rules
sl@0: // to determine whether the binary should be paged or not are the same as in the
sl@0: // preceding action.
