Short: Fixes for patch.library (V4.134)
Author: snfuchs@sokrates.franken.de
Uploader: snfuchs@sokrates.franken.de
Type: util/libs
This release of patch.library (V4.134) fixes the following bugs:
- Under rare conditions, patch.library would cause crashes.
- Patches that used PATT_SaveRegisters, crashed, if they were disabled.
Note: This tag will be dropped in V5.
- The low-memory handler now always tries to free memory, not only,
if not enough chip-ram is available.
- After temporarily detaching a patch in RemovePatchTags, reattaching
the patch did not work as it should, causing various problems
including recoverable alerts with PatchSetFunc.
(This bug was introduced with patch.library v4.112)
- PATT_AddTaskName and PATT_AddTaskID now install the same name/ID as
documented only once (removes possible enforcer hit).
- Patch.library uses the timer.device instead of dos.library Delay()
This fixes possible problems, when removing patches in a task context
(problems never seen)
- Some functions no longer block the semaphore in exclusive mode.
Shared mode is used on Kick V39+. This helps multitasking.
- Patch.library now ignores the usage-counter for dos.library/exit() and
exec.library/RemTask() functions, as these functions do not return
to the calling task.
- With the implementation of the low-memory handler (in V4.107) the Expunge
code could crash the machine
- The above bug however was hidden by another bug, which made it impossible to
remove all patches (One (deactivated) patch always remained in the lists)
- Patch.library could cause some (harmless) enforcer hits, when installing
patches
- New feature: On Kick 3.0 and above patch.library now installs
a low-memory handler
- Using the TaskList feature caused the patch to crash
(My Assembler was optimizing a jsr to bsr)
This fix makes PatchWBPens work again.
- patch.library, in conjunction with the support program PatchSetFunc,
was unable to remove patches, which replaced a whole function.
This also fixes crashes with LoadResource.
- patch.library did not work correctly with PatchControl:
It no longer writes directly into the jump-table, if the
support program PatchSetFunc is not installed.
It uses exec/SetFunction() instead.
- A possible deadlock problem, when waiting for a patch to finish has
been removed
- The task/taskname filtering system broke in early V4
