2012-03-06  Grant Edwards <grant.b.edwards@gmail.com>

        * src/malloc.cxx (free):
        * src/kapi.cxx (cyg_mempool_var_free, cyg_mempool_fix_free): Fix
        compiler warnings about variables that are set but never
        referenced. [ Bugzilla 1001511 ]

2009-09-01  Bart Veer  <bartv@ecoscentric.com>

        * src/heapgen.tcl (tcl_path): use the makefile's HOST instead of
        tcl_platform() to figure out host details.

2009-06-24  Nick Garnett  <nickg@ecoscentric.com>

        * src/malloc.cxx (cyg_memalloc_heap_reinit): Added this function
        to reinitialize the heap to a new arena. This should be done
        during system startup and is present mainly for the use of
        RedBoot.
        Permit configurations with multi-region heaps to build.
        [Imported from eCosPro sources, mainly to support use of
        filesystems in RedBoot].
        
2009-02-03  Simon Kallweit  <simon.kallweit@intefo.ch>

        * include/mvarimpl.inl:
        * include/sepmetaimpl.inl:
        Fixed a few compiler warnings.

2009-01-09  John Dallaway  <john@dallaway.org.uk>

        * cdl/memalloc.cdl: Invoke tclsh explicitly to avoid the need for
        execute permission on heapgen.tcl.

2009-01-08  John Dallaway  <john@dallaway.org.uk>

        * src/heapgen.tcl: Specify script interpreter via /usr/bin/env.
        * cdl/memalloc.cdl: Simplify heaps.cxx make rule - cygtclsh80 is
        no-longer supported.

2008-12-19  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/dlmalloc.cxx (MALLOC_COPY): Reinstate fix of 2008-01-06
        (reverting change of 2008-11-03).
        * cdl/memalloc.cdl (CYGIMP_MEMALLOC_ALLOCATOR_DLMALLOC_USE_MEMCPY):
        Make explicit dependency on isoinfra functionality block which
        includes memmove(), and set default_value accordingly.

2008-11-03  Nick Garnett  <nickg@ecoscentric.com>

        * src/dlmalloc.cxx (MALLOC_COPY): Replace memmove() with memcpy().

        * include/dlmallocimpl.hxx (class Cyg_Mempool_dlmalloc_Implementation):
        Remove spurious typedef in definition of struct malloc_chunk.

2008-01-06  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/dlmalloc.cxx (MALLOC_COPY): 
        * cdl/memalloc.cdl: Use memmove instead of memcpy which can go
        wrong in realloc() when the new and old block overlaps.
        CYGIMP_MEMALLOC_ALLOCATOR_DLMALLOC_USE_MEMCPY has been retained
        instead of being renamed to ..._MEMMOVE to help backward
        compatibility with older configurations. Thanks to Oyvind Harboe
        and Dave Lawrence.

2007-11-05  Oyvind Harboe <oyvind.harboe@zylin.com>
        
        * cdl/memalloc.cdl: Added option CYGBLD_MEMALLOC_MALLOC_EXTERNAL_JOIN_H
        to let applications implement a way to pick the pool to allocate memory
        from based on an application specific heuristic.
        * src/malloc.cxx: Use it.
        
2007-10-24  Oyvind Harboe <oyvind.harboe@zylin.com>
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>

        * include/memjoin.inl: Don't use default arg in definition.

2003-02-04  John Dallaway  <jld@ecoscentric.com>

        * src/heapgen.tcl: Accommodate POSIX-style arguments
        under Cygwin.

2003-01-29  John Dallaway  <jld@ecoscentric.com>

        * src/heapgen.tcl: Accommodate latest Cygwin Tcl shell

        * 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>

        * 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.
        * src/dlmalloc.cxx (get_status): Correct again calculation of maxfree

2001-06-28  Jonathan Larmour  <jlarmour@redhat.com>

        * include/memjoin.inl (~Cyg_Mempool_Joined): free even when asserts
        disabled.

        * include/memvar.hxx (class Cyg_Mempool_Variable): Comment out argument
        names for consistency.
        * include/memfixed.hxx (class Cyg_Mempool_Fixed): Ditto.
        * include/memjoin.hxx (class Cyg_Mempool_Joined): Ditto.

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

        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/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

        * 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
