I cannot remember the exact workings of the id values and the local_table. I might have changed the nature from the pre-unlimited change.

A static local variable `null_local_table' has been added. This variable is always set to NULL. The `**local_table' element of the information structure is set to point to this variable earily in the initialisation. If the object type has more than 0 elements the `local_table' element is updated. All object types which have 0 elements reference `null_local_table'. This change fixes the problem sp09 found yet does not add any extra processing to the critical `_Objects_Get_local_object' function. ---- CVS log ----
* Unlimited objects patch from Chris Johns <ccj@acm.org>. Email follows:Joel Sherrill1999-03-171-81/+483
| | | | | | | | | | | | | | | | | | | | | | | | | First, the unlimited patch. I have compiled the unlmited patch for the Linux posix BSP only and it seems to work cleanly. I would like a really major application run on this change before commiting as the changes are very core and significant. I am currently building all the tests to run. I have no targets suitable to test on at the moment. I have tested the patch for inline functions and macros. Turning macros on has found some core bugs. I have fixed these but have not run all the tests. Please review the patch for these changes. They are: 1) The conditional compilation for MP support broke the core messages code. You cannot embed a conditional macro in another macro. The Send and Urgent Send calls are macros. 2) User extensions handler initialisation now has two parameters. I have updated the macros to support the extra parameter. The patch also contains the gcc-target-default.cfg fix required to build the kernel. More of a by product than a fix for you.

* Patch from Eric Norum <eric@skatter.usask.ca>:Joel Sherrill1998-11-191-0/+8
| | | | | | | | | | | | | | | 1) Socket timeout field changed from `short' to `long'. This makes longer timeouts possible. With a 1 kHz system clock the old system allowed timeouts only up to a little over 30 seconds! This change is a slightly cleaned-up version of the patch proposed by Ian Lance Taylor. 2) Major changes to BOOTP/DHCP reply handling. Now supports much of RFC2132. These changes were done at the request of, and with the assistance of, Erik Ivanenko. If you're making changes, you might want to change the network supplement Essentially just do a global search and replace of BOOTP with BOOTP/DHCP.

| | | | | | | | | argument indicates whether the task is to be placed at the head or tail of its priority fifo when it is lowering its own priority. POSIX normally follows the RTEMS API conventions but GNAT expects that all lowering of a task's priority by the task itself will result in being placed at the head of the priority FIFO. Normally, this would only occur as the result of lose of inherited priority.

| | | | | | | | | | the thread handler (IDLE), MPCI object (SYSI now MP Receive) and initialize_executive_early (IO initialization). The SYSI task no longer exists in a single processor configuration. This reduces single processor Workspace requirements by a TCB and a stack which is often larger than the minimum stack size. Moving the IO initialization plus accompanying BSP hooks eliminated an initialization ordering problem in which a global task could be created before the MPCI was initialized.
