146
1472001-05-02  Hugo Tyson  <hmt@redhat.com>
148
149        * src/dlmalloc.cxx (Cyg_Mempool_dlmalloc_Implementation): Fix
150        previous change; "top" is a pseudo variable via a NULL pointer if
151        the heap is not initialized, so you can't use it as a flag for "no
152        mem here"; and a typo, the comparison was reversed.  The two hid
153        each other, so the check for "no mem here" usually said "OK".
154

156
157        * include/mvarimpl.inl (try_alloc): Allow zero sized heaps.

161
1622001-04-12  Hugo Tyson  <hmt@redhat.com>
163

165        This only applies if you configure multiple heaps.
166
1672001-03-21  Jonathan Larmour  <jlarmour@redhat.com>
168
169        * cdl/memalloc.cdl: Specify explicit output file when preprocessing
170        heapgen.cpp. Improves portability.
171
1722001-02-01  Jonathan Larmour  <jlarmour@redhat.com>
173
174        * tests/malloc4.cxx: Use semaphores to sync startup order.
175
1762000-11-28  Jonathan Larmour  <jlarmour@redhat.com>
177
178        * src/heapgen.tcl: Don't use cygpath -s for now as not all cygwins

180
1812000-11-25  Jonathan Larmour  <jlarmour@redhat.com>
182
183        * cdl/memalloc.cdl: Make sure PWD variable doesn't clash with bash PWD
184        by renaming to XPWD

189        surrounded by quotes (and do so in a portable way).
190
191        * src/heapgen.tcl: recurse back in on cygwin with correct quoting
192        to allow directories containing spaces. Also in a Solaris shell
193        compatible way.
194
1952000-11-21  Jonathan Larmour  <jlarmour@redhat.com>
196
197        * cdl/memalloc.cdl (CYGSEM_MEMALLOC_MALLOC_ZERO_RETURNS_NULL):
198        New option.
199        * src/malloc.cxx (malloc): Use above option to decide if NULL should
200        be returned on malloc(0).
201
2022000-11-01  Jesper Skov  <jskov@redhat.com>
203
204        * tests/realloc.c (main): Use reasonable factor when making too
205        large realloc (targets with 64MB would cause an overflow).
206
2072000-10-31  Jonathan Larmour  <jlarmour@redhat.com>
208
209        * tests/testaux.hxx: Prototype cyg_hal_invoke_constructors()

229
2302000-08-31  Jonathan Larmour  <jlarmour@redhat.com>
231
232        * cdl/memalloc.cdl: Make dlmalloc the default malloc implementation now.

254        Ensure typedefs are public so dlmalloc.cxx can use them at outer level.
255
2562000-08-02  Jonathan Larmour  <jlarmour@redhat.co.uk>
257
258        * src/heapgen.tcl: Fix tclsh invocation quoting problems
259
2602000-07-31  Jonathan Larmour  <jlarmour@redhat.co.uk>
261
262        * src/heapgen.tcl: Allow builddir to be specified on command-line
263        * cdl/memalloc.cdl: Work around NT cygtclsh80 bug by cd'ing into

282        Default to 1
283

285        freelist entries when extending block
286
2872000-07-04  Jonathan Larmour  <jlarmour@redhat.co.uk>
288
289        * CYGPKG_MEMALLOC:
290
291        Created as new package, merging existing memory allocator related stuff
292        from the kernel and libc. Many bug fixes to existing stuff, as
293        well as performance improvements, and extra features such as
294        a port of dlmalloc, and the ability to support multiple disjoint
295        heaps, possibly with run-time configurable size.
296        There's even a bit of documentation, and some new tests
