* POSIX message queues now include complete functionality includingJoel Sherrill2000-01-132-69/+96
| | | | | | | | | | | | | | | | blocking sends when the queue is full. The SuperCore was enhanced to support blocking on send. The existing POSIX API was debugged and numerous test cases were added to psxmsgq01 by Jennifer Averett. SuperCore enhancements and resulting modifications to other APIs were done by Joel. There is one significant point of interpretation for the POSIX API. What happens to threads already blocked on a message queue when the mode of that same message queue is changed from blocking to non-blocking? We decided to unblock all waiting tasks with an EAGAIN error just as if a non-blocking version of the same operation had returned unsatisfied. This case is not discussed in the POSIX standard and other implementations may have chosen differently.

* Added support for simple binary semaphores in addition to the highJoel Sherrill2000-01-053-32/+42
| | | | | | | | | | | | power binary/mutex style semaphores already supported by RTEMS. This was done at the request of Eric Norum <eric@cls.usask.ca> in support of his effort to port EPICS to RTEMS. This change consisted of changing the nesting_allowed boolean into a lock_nesting_behavior enumerated value as well as allowing the core mutex object to optionally support ensuring that the holder of a binary semaphore released it. Finally, a more subtle enhancement was to allow the non-holder to release a priority inheritance/ceiling mutex and still allow the holding task to return to its original priority.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: a posix thread which is created by pthread_attr_init(&tattr); pthread_attr_setinheritsched(&tattr, PTHREAD_EXPLICIT_SCHED); pthread_attr_setschedpolicy(&tattr, SCHED_RR); pthread_create(&th, &tattr, func, arg); has a first timeslice of 2^32 ticks (changing a running thread to SCHED_RR id ok). I use RTEMS-4.0.0. I am not sure if the problem exists in the current CVS head revision. If it's not fixed, the patch at the end should do it.

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.
