2007-10-24  Jonathan Larmour  <jifl@eCosCentric.com>

	* src/malloc.cxx: Init priority for pool initialization is now
	CYG_INIT_MEMALLOC instead of before CYG_INIT_LIBC

	* src/heapgen.tcl: Ditto.

2006-05-17  Andrew Lunn  <andrew.lunn@ascom.ch>

	* doc/memalloc.sgml: Fix parameters for calloc. Reported by
	Andy Jackson.

2005-09-30  Alexander Neundorf <neundorf@kde.org>

        * doc/memalloc.sgml: two minor fixes

2005-07-30  Andrew Lunn  <andrew.lunn@ascom.ch>

	* tests/heaptest.c (test_pat): Casts to prevent compiler warnings.
	* tests/testaux.hxx: new cannot be both global and static.

2005-07-22  Andrew Lunn  <andrew.lunn@ascom.ch>

	* cdl/memalloc.cdl: Use the CXXFLAGS for the native compiler to
	avoid passing it flags only valid for C.

2005-03-27  Andrew Lunn  <andrew.lunn@ascom.ch>

	* cdl/memalloc.cdl: Added reference to documentation
	* doc/memalloc.sgml: Basic user documentation.
	* tests/heaptest.c (test_pat): Fix compiler error with 
	  diag_printf.

2004-10-04  Oyvind Harboe  <oyvind.harboe@zylin.com>

	* src/dlmalloc.cxx (resize_alloc): No longer invoke
	 cyg_memalloc_alloc_fail() on failure to resize. It is not an out
	 of memory condition, it just means the current memory allocation
	 could not be expanded. realloc() will try allocating a completely
	 new block of memory and only if that fails do we have an out of
	 memory condition.

2004-10-01  Oyvind Harboe  <oyvind.harboe@zylin.com>

	* heapgen.tcl: place the CYGBLD_ATTRIB_INIT_PRI such that it
	compiles for gcc 3.4.2 which is more picky about its placement.

2004-06-24  Oyvind Harboe  <oyvind.harboe@zylin.com>

	* Added cyg_memalloc_alloc_fail() fn which is invoked before 
	return NULL from failed allocations. Useful breakpoint site.
	Andrew Lunn wrote some of the code and pointed out various
	wrinkles to be ironed out.

2004-02-15  Jonathan Larmour  <jifl@eCosCentric.com>

	* include/kapi.h: Add throw specifications throughout.
	* src/kapi.cxx: Ditto.

2003-10-06  Andrew Lunn  <andrew.lunn@ascom.ch>

	* src/dlmalloc.cxx (Cyg_Mempool_dlmalloc_Implementation): Fixed
	compiler warning added by previous patch.

2003-09-30  Eric Doenges <Eric.Doengea@DynaPel.com>

	* cdl/memalloc.cdl, src/dlmalloc.cxx: Make the minimum memory
	alignment a configuration option for Doug Lea's memory allocator.

2003-02-05  Jonathan Larmour  <jifl@eCosCentric.com>

	(tclsh83.exe)

	* tests/heaptest.c (test_pat): Make failure messages clearer.
	(cyg_start): Output what failures mean.

2002-04-24  Yoshinori Sato  <qzb04471@nifty.ne.jp>

	* src/memfixed.cxx (resize_alloc): Don't set default args in func
	definition.

2002-01-30  Bart Veer  <bartv@redhat.com>

	* tests/malloc4.cxx:
	Never call realloc() with a new size of 0, which frees the buffer.
	Fix the volatility of ptr.p

2002-01-23  Jesper Skov  <jskov@redhat.com>

	* tests/malloc4.cxx (myrand): Fix overflow.

2002-01-15  Jonathan Larmour  <jlarmour@redhat.com>

	* tests/malloc4.cxx (myrand): Fix so that it really treats the limit
	as a limit.

2001-10-17  Jesper Skov  <jskov@redhat.com>

	* include/sepmetaimpl.inl: CYGINT_ISO_STRING_MEMFUNCS checks
	changed to ifdef.

2001-10-11  Jesper Skov  <jskov@redhat.com>

	* tests/testaux.hxx (new_thread): Fixed allocation: increase
	counter before starting threads which have been allocated
	resources.

2001-10-08  Jonathan Larmour  <jlarmour@redhat.com>

	* tests/heaptest.c: Added some extra output on failures.

2001-08-01  Jonathan Larmour  <jlarmour@redhat.com>

	* include/sepmetaimpl.inl: Define check_free_memdq and
	check_alloced_memdq as inlines.

	* cdl/memalloc.cdl: Add new allocator supporting separate metadata,
	and the associated config options, and build sepmeta.cxx and tests.
	Build heapgeninc.tcl with macros that work with both gcc2 and gcc3.
	Ditto for heaps.o.
	Add CYGBLD_MEMALLOC_MALLOC_EXTERNAL_HEAP_H to allow external entities
	to define the heap.
	* src/malloc.cxx: Include CYGBLD_MEMALLOC_MALLOC_EXTERNAL_HEAP_H if
	defined instead of default heap definition.
	* include/sepmeta.hxx, include/sepmetaimpl.hxx, include/sepmetaimpl.inl,
	src/sepmeta.cxx, tests/sepmeta1.cxx, tests/sepmeta2.cxx:
	New files for seperated metadata allocator.

2001-07-18  Jonathan Larmour  <jlarmour@redhat.com>

	* src/heapgen.tcl: Use constructor priority of CYG_INIT_MEMALLOC
	for heap objects in generated heaps.cxx.

2001-07-12  Jonathan Larmour  <jlarmour@redhat.com>

	* tests/malloc1.c (main): Accoutn for allocators that do allocate
	space for allocs of 0.
	Test that allocating all space works.

	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.

	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.

	* 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>

	describe the pros and cons of these allocators.

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

	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>

	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
