2001-06-20  Jonathan Larmour  <jlarmour@redhat.com>

	* include/mvarimpl.inl (get_status): Correct calculation of maxfree
	by taking into account metadata.

2001-06-18  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/memalloc.cdl: Add heaptest test.

	* tests/heaptest.c: New test to do a memory check of all of heap.

	* src/dlmalloc.cxx (get_status): Correct maxfree and totalfree
	by accounting for block headers.

	* tests/realloc.c (cyg_start): Remove warning from declaration.
	* tests/malloc1.c (cyg_start): Ditto.
	* tests/malloc2.c (cyg_start): Ditto.
	* tests/malloc3.c (cyg_start): Ditto.
	* tests/malloc4.cxx (cyg_start): Ditto. Also add DEBUGTEST define
	and fix comment.

	* tests/testaux.hxx (STACKSIZE): Double.

2001-05-02  Hugo Tyson  <hmt@redhat.com>

	* src/dlmalloc.cxx (Cyg_Mempool_dlmalloc_Implementation): Fix
	previous change; "top" is a pseudo variable via a NULL pointer if
	the heap is not initialized, so you can't use it as a flag for "no
	mem here"; and a typo, the comparison was reversed.  The two hid
	each other, so the check for "no mem here" usually said "OK".

2001-05-01  Jonathan Larmour  <jlarmour@redhat.com>

	* include/mvarimpl.inl (try_alloc): Allow zero sized heaps.
	(Cyg_Mempool_Variable_Implementation): Ditto.
	* src/dlmalloc.cxx (try_alloc): Ditto.
	(Cyg_Mempool_dlmalloc_Implementation): Ditto.

2001-04-12  Hugo Tyson  <hmt@redhat.com>

	* include/memjoin.inl (resize_alloc): Fix typo so it compiles.
	This only applies if you configure multiple heaps.

2001-03-21  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/memalloc.cdl: Specify explicit output file when preprocessing
	heapgen.cpp. Improves portability.

2001-02-01  Jonathan Larmour  <jlarmour@redhat.com>

	* tests/malloc4.cxx: Use semaphores to sync startup order.

2000-11-28  Jonathan Larmour  <jlarmour@redhat.com>

	* src/heapgen.tcl: Don't use cygpath -s for now as not all cygwins
	have it yet.

2000-11-25  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/memalloc.cdl: Make sure PWD variable doesn't clash with bash PWD
	by renaming to XPWD

2000-11-24  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/memalloc.cdl: Invoke heapgen.tcl with build directory
	surrounded by quotes (and do so in a portable way).

	* src/heapgen.tcl: recurse back in on cygwin with correct quoting
	to allow directories containing spaces. Also in a Solaris shell
	compatible way.

2000-11-21  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/memalloc.cdl (CYGSEM_MEMALLOC_MALLOC_ZERO_RETURNS_NULL): 
	New option.
	* src/malloc.cxx (malloc): Use above option to decide if NULL should
	be returned on malloc(0).

2000-11-01  Jesper Skov  <jskov@redhat.com>

	* tests/realloc.c (main): Use reasonable factor when making too
	large realloc (targets with 64MB would cause an overflow).

2000-10-31  Jonathan Larmour  <jlarmour@redhat.com>

	* tests/testaux.hxx: Prototype cyg_hal_invoke_constructors()
	[ Forgot to check this in at the same time as below ]

2000-10-20  Jonathan Larmour  <jlarmour@redhat.com>

	* tests/dlmalloc1.cxx:
	* tests/dlmalloc2.cxx:
	* tests/malloc4.cxx:
	* tests/memfix1.cxx:
	* tests/memfix2.cxx:
	* tests/memvar1.cxx:
	* tests/memvar2.cxx:
	Make sure default priority constructors have been invoked.

2000-09-14  Jesper Skov  <jskov@redhat.com>

	* tests/realloc.c (main): fix warning.
	* tests/malloc1.c (main): Same.
	* tests/malloc2.c (main): Same.
	* tests/malloc3.c (main): Same.

2000-08-31  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/memalloc.cdl: Make dlmalloc the default malloc implementation now.
	Also add info to the variable block and dlmalloc descriptions to
	describe the pros and cons of these allocators.

2000-08-09  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* tests/malloc4.cxx (thrfree): Don't yield at loop end - actually delay
	(thrrealloc): Ditto
	(thrcalloc): Ditto
	(thrmalloc): Ditto

2000-08-08  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* tests/malloc4.cxx: Make output more frequent

2000-08-04  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* tests/dlmalloc1.cxx (STACKSIZE): Define larger than default.

2000-08-03  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/dlmallocimpl.hxx (class Cyg_Mempool_dlmalloc_Implementation):
	Ensure typedefs are public so dlmalloc.cxx can use them at outer level.

2000-08-02  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* src/heapgen.tcl: Fix tclsh invocation quoting problems

2000-07-31  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* src/heapgen.tcl: Allow builddir to be specified on command-line
	* cdl/memalloc.cdl: Work around NT cygtclsh80 bug by cd'ing into
	heapgen.tcl's directory before running it

2000-07-26  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* tests/malloc4.cxx: Call rand_r() rather than rand, and use a seed
	var in each thread.

2000-07-25  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* tests/malloc4.cxx (thrfree): Get mem size here. Tidy output.
	(thrmalloc): Get mem size in thrfree instead

	* src/heapgen.tcl: Refine search for user-defined name to cope with
	use of CYG_LABEL_DEFN macro

2000-07-19  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* cdl/memalloc.cdl (CYGIMP_MEMALLOC_ALLOCATOR_DLMALLOC_SAFE_MULTIPLE):
	Default to 1

	* include/mvarimpl.inl (resize_alloc): Remember to adjust other
	freelist entries when extending block

2000-07-04  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* CYGPKG_MEMALLOC:

	Created as new package, merging existing memory allocator related stuff
	from the kernel and libc. Many bug fixes to existing stuff, as
	well as performance improvements, and extra features such as
	a port of dlmalloc, and the ability to support multiple disjoint
	heaps, possibly with run-time configurable size.
	There's even a bit of documentation, and some new tests
