This is release 1.108.1, made on 2007-12-21.

Changes from release 1.108.0:

|
||||
Functional changes to MPS code:
|
||||
|
||||
<http://www.ravenbrook.com/project/mps/issue/job001737/>
|
||||
Limitation:
|
||||
- if a VM arena (of mps_arena_class_vm) needed to be extended,
|
||||
and the attempt to extend it was refused by the OS (usually
|
||||
because the requested address-space was not available), MPS
|
||||
would not try a smaller extension.
|
||||
Fixed: MPS now tries to extend the arena by successively smaller
|
||||
amounts, until the extension succeeds.
|
||||
|
||||
<http://www.ravenbrook.com/project/mps/issue/job001706/>
|
||||
Defect discovered:
|
||||
- internal memory-protection state in AMC pools (mps_class_amc)
|
||||
was incorrect for a brief period of time during a collection,
|
||||
which could (theoretically) have caused an assert and failure.
|
||||
However:
|
||||
- during this brief period, the MPS protection cache masks the
|
||||
defect. As a result, we believe this defect is unlikely to be
|
||||
observed in practice (and we have no evidence that it has
|
||||
ever occurred in practice).
|
||||
Fixed: maintain memory-protection state correctly in AMC pools.
|
||||
|
||||
Other changes:
|
||||
|
||||
<http://www.ravenbrook.com/project/mps/issue/job001714/>
|
||||
- in the Mac OS X (PowerPC) build, remove outdated compiler flags.
|
||||
|
||||
The MPS diagnostic system -- which produces diagnostic output for the
|
||||
purpose of helping MPS programmers and client-code programmers -- is
|
||||
undergoing improvement. Some early documentation is at
|
||||
<http://www.ravenbrook.com/project/mps/master/design/diag>
|
||||
There is a new build variety "di" that emits diagnostics.
