Log:
[NTDLL]
- Add parameter annotations.
- Improve CSR buffer allocation with 4-byte align.
- Simplify the capture-buffer pointers settings.
[CSRSRV]
- Remove last console structure from csrsrv.h (in next commits it will be placed in a
proper header).
- Enable global CSR debugging (for debugging purposes... ;-) ).
- api.c: Enable debugging.
- api.c/.h: Remove old code and deprecated unused definitions.
- Use the Win2k3-compliant version of CsrCreateThread (code from subsystems/csr/csrsrv)
(TODO: correct its usage in basesrv:BaseSrvCreateThread).
- init.c: Implement a helper routine, CsrInitCsrRootProcess, in order to initialize the
per-process server data (see CSR_PROCESS structure) in the Root CSR process. New process
inherit it from this Root process.
- server.c - Add a DPRINT. Remove a hack. Correct a parameter passing.
- session.c - Remove a hack (it will go to the new process initialization in consrv)
- Disable the code of CsrConnectToUser while user32:ClientThreadSetup doesn't work.
- Correct the implementation of CsrValidateMessageBuffer.
- Basic implementation of CsrValidateMessageString using CsrValidateMessageBuffer.
TODO:
- Compare CsrpHandleConnectionRequest with the other one function in api.c.
- Compare CsrValidateMessageBuffer with Win32CsrValidateBuffer ?
