2009-06-12 Massimiliano Mantione <massi@ximian.com>
* ObjectModel.cs: added method execution time accounting on
individual stack frames in the call tree.
2009-06-09 Mike Kestner <mkestner@novell.com>
* ObjectModel.cs: commit Massi's calls StackTrace logging.
2009-05-21 Mike Kestner <mkestner@novell.com>
* *: replace MD 1.0 solution files with 2.0 msbuild files, and turn
on makefile synchronization instead of generated makefiles.
2009-04-06 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs, Decoder.cs, ObjectModel.cs, EventProcessor.cs:
Added support for monitor profiling.
2009-03-17 Massimiliano Mantione <massi@ximian.com>
* ObjectModel.cs: In "IHeapItemSetStatisticsSubject.Description"
implementations return the full method name.
2009-03-16 Massimiliano Mantione <massi@ximian.com>
* ObjectModel.cs: fixed description string of "referenced by" subset.
2009-01-17 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs: Added "Region" property to IExecutableMemoryRegion, so
that it is possible to set the region when we load the elf file, and
use it in "BaseExecutableMemoryRegion.NewFunction".
* Decoder.cs, ObjectModel.cs, NativeLibraryReader.cs: Likewise.
2008-12-29 Massimiliano Mantione <massi@ximian.com>
* ObjectModel.cs: fixed call stack array resize condition.
2008-12-01 Massimiliano Mantione <massi@ximian.com>
* ObjectModel.cs:
- Added interface IHeapItemSetStatisticsSubject to represents criteria
by which heap item sets can be examined, implemented by LoadedClass,
StackTrace and LoadedMethod.
- Added methods to IHeapItem (and implementations) to get the item
allocator method and call stack.
- Added filter classes (FilterHeapItemByAllocatorMethod,
HeapItemWasAllocatedByMethod, FilterHeapItemByAllocationCallStack...)
to filter by those criteria.
- Added abstract class HeapItemSetStatisticsBySubject to factor the
building of statistics (implemented by HeapItemSetClassStatistics,
HeapItemSetMethodStatistics and HeapItemSetCallStackStatistics).
- Inside HeapItemSet added the BuildStatistics generic method (which
works with the previous classes).
- Inside HeapItemSet added the FindObjectAllocations functionality.
2008-11-03 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs: Added "header start time" property to the event
handler, so that there is always a "context" of when the event block
happened diring the execution. Added also this time as a parameter to
the heap snapshot factory and constructor.
* Decoder.cs: Likewise.
* Reader.cs: Likewise.
* EventProcessor.cs: Likewise. Moreover, fixed case of public
properties and added ability to record each allocation individually
(up to now the data was only aggregated, see "AllocatedObject").
* ObjectModel.cs: Massive refactory of "HeapObjectSet", making it
generic so that it can be a set of IHeapItem (which in turn can be a
HeapObject or an AllocatedObject).
This enables exploring heap snapshots and relating each objectg to its
allocation event.
Also added filtering based on "references objects in another set".
2008-10-13 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs: Turn HeapObject class into generic BaseHeapObject class,
and add a new IAllocatedObject interface (this will give more freedom
when implementing HeapObject and AllocatedObject separately).
* ObjectModel.cs: Derive HeapObject from BaseHeapObject.
* EventProcessor.cs: Likewise.
2008-10-12 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs: Added support for object ids in allocation events.
* ObjectModel.cs: Likewise.
* EventProcessor.cs: Likewise.
2008-10-10 Massimiliano Mantione <massi@ximian.com>

- Added support for handling the stack trace of each allocation event.
- Added a DebugProfilerEventHandler which helps detecting decoder bugs.
* ObjectModel.cs: Likewise.
* EventProcessor.cs: Likewise.
* Decoder.cs: Likewise.
2008-09-17 Massimiliano Mantione <massi@ximian.com>

which happened at JIT time.
* ObjectModel.cs: Likewise.
* Decoder.cs: Likewise.
* EventProcessor.cs: Likewise.
2008-08-20 Massimiliano Mantione <massi@ximian.com>

2008-08-05 Massimiliano Mantione <massi@ximian.com>
* Reader.cs: If the file is truncated "cleanly" do not throw exceptions.
2008-08-04 Massimiliano Mantione <massi@ximian.com>
Removed .pc file generation.
2008-08-01 Massimiliano Mantione <massi@ximian.com>
* Makefile.am, profiler-decoder-library.mdp: renamed output assembly.
2008-08-01 Massimiliano Mantione <massi@ximian.com>

2008-05-12 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs: Added a flag to ILoadedElementFactory and
IHeapSnapshot to specify if the snapshot objects must be created
in memory or not, so that memory is not wasted if the user is only
interested in the other profiling info.
* Decoder.cs: Likewise.
* ObjectModel.cs: Likewise, and cleaned up "heap-desc" functionality.
* EventProcessor.cs: Likewise.
2008-05-12 Massimiliano Mantione <massi@ximian.com>
* BaseTypes.cs: Added support for garbage collection counter.

* BaseTypes.cs: Changed FIXME comment.
2008-05-02 Massimiliano Mantione <massi@ximian.com>

symbols (statistical hits not found on symbol tables).
* ObjectModel.cs: Similar changes to handle unmanaged symbols.
* BaseTypes.cs: Likewise.
2008-04-16 Massimiliano Mantione <massi@ximian.com>
* ObjectModel.cs: Added heap object set comparison operation.
2008-04-16 Massimiliano Mantione <massi@ximian.com>

* ObjectModel.cs: Initial implementation of heap object sets.
2008-04-11 Massimiliano Mantione <massi@ximian.com>
