Problem reported by Wolfgang Jenkner in: http://bugs.gnu.org/22086#118
* src/gmalloc.c (__malloc_initialize_hook, __after_morecore_hook)
(__morecore) [HYBRID_MALLOC]: Define in this case too.
* doc/misc/Makefile.in (${buildinfodir}/tramp.info tramp.html):
No EXTRA_OPTS needed.
* doc/misc/tramp.texi: Merge changes from Emacsemacs-25
branch, especially for @trampfn{}.
(Top): Move @ifnottex down.
(History): XEmacs support has been removed.
(GVFS based methods, Remote processes): Do not use emacsgvfs flag.
(Auto-save and Backup): Use both syntax versions.
(File name Syntax): Remark on IPv6 adresses is valid for
unified syntax only.
* doc/misc/trampver.texi: Do not set emacsgvfs flag.
* src/sheap.h: Include lisp.h, for Lisp_Object.
(STATIC_HEAP_SIZE): Now an enum constant, not a macro.
Make it 2 MiB * sizeof (Lisp_Object), which is a bit more
conservative than the old value.
(Bug#22086)
* src/alloc.c: Always include <signal.h>.
(malloc_warning) [!SIGDANGER && (SYSTEM_MALLOC || HYBRID_MALLOC)]:
Do not define; unused.
* src/emacs.c, src/lisp.h (might_dump) [!DOUG_LEA_MALLOC]: Now static.
* src/gmalloc.c (gdefault_morecore): Rename from __default_morecore,
to avoid collision with glibc. Now static. All uses changed.
* src/lastfile.c (my_edata): Define only if
((!defined SYSTEM_MALLOC && !defined HYBRID_MALLOC && !defined
WINDOWSNT) \ || defined CYGWIN || defined DARWIN_OS).
(Bug#22086)
* configure.ac (hybrid malloc): Simplify configuration.
(SHEAP_OBJ): Remove; no longer needed.
(HYBRID_MALLOC): New var. Subst it.
(HYBRID_MALLOC_LIB): New Automake conditional.
* lib/Makefile.am (noinst_LIBRARIES): Add libegnu.a only if
HYBRID_MALLOC_LIB.
(libegnu_a_CPPFLAGS): Omit AM_CPPFLAGS; not needed.
(MOSTLYCLEANFILES): Add libegnu.a.
* src/Makefile.in (SHEAP_OBJ): Remove.
(HYBRID_MALLOC): New macro.
(base_obj): Use it to conditionally add sheap.o.
(LIBEGNU_ARCHIVE): New macro.
($(LIBEGNU_ARCHIVE)): New rule, replacing $(lib)/libegnu.a.
All uses of the latter replaced by the former.
* src/alloc.c (USE_ALIGNED_ALLOC): Simplify configuration.
Correct misspelling ALIGNED_ALLOC to HAVE_ALIGNED_ALLOC.
* src/gmalloc.c: Update comment.
* src/lisp.h (aligned_alloc)
[!DOUG_LEA_MALLOC && !HYBRID_MALLOC && !SYSTEM_MALLOC]:
New decl.
(Bug#22086)
This should help insulate us better from future glibc changes.
It is good hygiene to include .h files for APIs that Emacs uses.
Fix type clashes between Emacs and GNU <malloc.h> (Bug#22086).
* configure.ac: Check for malloc.h.
* src/alloc.c: Include <malloc.h> depending on HAVE_MALLOC_H,
not on DOUG_LEA_MALLOC.
* src/emacs.c, src/gmalloc.c (malloc_enable_thread):
Remove decl (now in lisp.h).
* src/gmalloc.c: Include stddef.h earlier, for ptrdiff_t.
[emacs]: Include lisp.h.
[HAVE_MALLOC_H]: Include <malloc.h>.
(__MALLOC_HOOK_VOLATILE): New macro, if not already defined.
(__after_morecore_hook, __malloc_initialize_hook, __morecore)
(__default_morecore):
[!HAVE_MALLOC_H]: New decls near non-inclusion of <malloc.h>.
(calloc): Make it clear that the macro should not be used.
Remove unused decl.
(malloc_info): New macro, to avoid clash with glibc <malloc.h>.
(__morecore, __default_morecore, __after_morecore_hook)
(__malloc_extra_blocks, __malloc_initialize_hook, __free_hook)
(__malloc_hook, __realloc_hook, __memalign_hook, memory_warnings):
Remove later decls.
(gmalloc_hook, gfree_hook, grealloc_hook):
Rename from __malloc_hook, __free_hook, __realloc_hook to
avoid type collision with glibc <malloc.h>. All uses changed.
(gmalloc_hook):
(__malloc_extra_blocks) [DOUG_LEA_MALLOC||HYBRID_MALLOC||SYSTEM_MALLOC]:
Now static.
(gmalloc_hook, __malloc_extra_blocks): Define even if [!HYBRID_MALLOC].
(__malloc_initialize_hook, __after_morecore_hook):
Declare with types compatible with glibc.
(__memalign_hook, hybrid_calloc) [HYBRID_MALLOC]:
Remove. All uses removed.
* src/lisp.h (__malloc_extra_blocks, malloc_enable_thread): New decls.
* src/ralloc.c, src/vm-limit.c:
Simplify includes and include <malloc.h> if available.
(alloc_unexec_pre, alloc_unexec_post) [HYBRID_MALLOC]:
Set and clear bss_sbrk_did_unexec, on all platforms not just Cygwin.
* src/lisp.h (alloc_unexec_pre, alloc_unexec_post) [!DOUG_LEA_MALLOC]:
Declare unconditionally.
* src/unexcw.c, src/unexelf.c (bss_sbrk_did_unexec): Remove decl.
(unexec): Don’t set or clear bss_sbrk_did_unexec;
the caller now does this.
(Bug#22086)
* src/buffer.c (init_buffer):
* src/emacs.c (main):
* src/xsmfns.c (smc_save_yourself_CB, x_session_initialize):
Use emacs_get_current_dir_name, not get_current_dir_name.
* src/conf_post.h (aligned_alloc) [HYBRID_MALLOC && emacs]: New macro.
(HYBRID_GET_CURRENT_DIR_NAME, get_current_dir_name): Remove.
* src/emacs.c: Include "sheap.h".
(report_sheap_usage): Remove decl.
(Fdump_emacs) [HYBRID_MALLOC]: Report usage directly.
Don't assume ptrdiff_t can be printed as int.
* src/gmalloc.c [HYBRID_MALLOC]:
Include "sheap.h" rather than declaring its contents by hand.
(get_current_dir_name, gget_current_dir_name)
(hybrid_get_current_dir_name): Remove.
(emacs_abort): Remove duplicate decl.
(aligned_alloc): Undef, like malloc etc.
(ALLOCATED_BEFORE_DUMPING): Now a static function, not a macro.
Make it a bit more efficient.
(malloc_find_object_address): Remove unused decl.
(enum mcheck_status, mcheck, mprobe, mtrace, muntrace, struct mstats)
(mstats, memory_warnings): Declare only if GC_MCHECK.
* src/lisp.h (emacs_get_current_dir_name):
New decl, replacing get_current_dir_name.
* src/sheap.c: Include sheap.h first.
(STATIC_HEAP_SIZE): Remove; now in sheap.h.
(debug_sheap): Now static.
(bss_sbrk_buffer_end): Remove; no longer used.
(bss_sbrk_ptr): Now static and private.
(bss_sbrk_did_unexec): Now bool.
(BLOCKSIZE): Remove, to avoid GCC warning about its not being used.
(bss_sbrk): Don't treat request_size 0 as special, since the code
works without this being a special case.
Avoid overflow if request size exceeds INT_MAX.
(report_sheap_usage): Remove; now done in emacs.c.
* src/sheap.h: New file.
* src/sysdep.c (get_current_dir_name): Remove macro.
Include "sheap.h".
(emacs_get_current_dir_name): Rename function from
get_current_dir_name. Handle HYBRID_MALLOC here;
this is simpler.
(Bug#22086)
* src/emacs.c (Fdump_emacs) [HYBRID_MALLOC]: Report sheap usage here ...
* src/unexcw.c (unexec): ... instead of here, since sheap can be used
on platforms other than Cygwin (Bug#22086).
* src/gmalloc.c: Adjust for HYBRID_MALLOC in the non CYGWIN case.
(__default_morecore): Here, in particular.
* configure.ac: Define HYBRID_MALLOC when unexelf.o is used.
New variable SHEAP_OBJ.
* src/Makefile.in: Use it.
(Bug#22086)
This is done to support HYBRID_MALLOC, since some static variables
(e.g., last_environ in putenv.c) hold pointers to memory malloced
before dumping (Bug#22086).
* lib/Makefile.am: Add incantation to install libegnu.a.
* src/Makefile.in ($(lib)/libgnu.a): Replace with libegnu.a
(temacs$(EXEEXT)): Use it.
This avoids clashes with symbols if the after-dump malloc is
derived from Doug Lea's implementation (Bug#22086).
* src/gmalloc.c (emacs_abort, __morecore, __default_morecore):
Move declarations up. For HYBRID_MALLOC, turn all `extern'
declarations below to `static' ones.
(aligned_alloc): Declare for !MSDOS as well.
(heapsize, _fraghead): Move resp. copy declaration downwards.
For HYBRID_MALLOC, conditionalize out the other definitions,
since the previous `static' declarations double as tentative
definitions, anyway.
(_malloc, _free, _realloc, __free_hook, _aligned_blocks)
(__realloc_hook, __memalign_hook): Conditionalize out.
(cfree, memalign, valloc): Ditto.
