2012-07-24Simplify copy_overlay.Dmitry Antipov
* buffer.c (copy_overlay): Simplify, use build_marker. * lisp.h (struct Lisp_Overlay): Restore comment with minor tweaks.
2012-07-23Cleanup miscellaneous objects allocation and initialization.Dmitry Antipov
* alloc.c (allocate_misc): Change to static. Add argument to specify the subtype. Adjust comment and users. (build_overlay): New function. * buffer.c (copy_overlays, Fmake_overlay): Use it. * lisp.h (struct Lisp_Overlay): Remove obsolete comment. (allocate_misc): Remove prototype. (build_overlay): Add prototype.
2012-07-23Swap buffer text indirection counters in Fbuffer_swap_text.Dmitry Antipov
* buffer.c (Fbuffer_swap_text): Swap indirections too. This avoids crash reported by Christoph Scholtes at http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2012-07-20Add indirection counting to speed up Fkill_buffer.Dmitry Antipov
* buffer.h (struct buffer): New member. * buffer.c (Fget_buffer_create): Set indirection counter to 0. (Fmake_indirect_buffer): Set indirection counter to -1, increment base buffer indirection counter. (compact_buffer): If ENABLE_CHECKING, verify indirection counters. (Fkill_buffer): Adjust indirection counters as needed, don't walk through buffer list if indirection counter is 0.
2012-07-20Extend the value returned by Fgarbage_collect with heap statistics.Dmitry Antipov
* alloc.c (Qheap): New symbol. (syms_of_alloc): DEFSYM it. (Fgarbage_collect): If DOUG_LEA_MALLOC, add mallinfo data. (Fmemory_free): Remove. (syms_of_alloc): Don't defsubr it. * buffer.c (Fcompact_buffer): Remove. (syms_of_buffer): Don't defsubr it.
2012-07-19* buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.Paul Eggert
(FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from 'for_each_per_buffer_object_at'. All uses changed. It's better to use upper-case for macros that cannot be implemented as functions, to give the reader a clue that they're special.

2012-07-10EMACS_TIME simplification (Bug#11875).Paul Eggert
This replaces macros (which typically do not work in GDB) with functions, typedefs and enums, making the code easier to debug. The functional style also makes code easier to read and maintain. * lib-src/profile.c (TV2): Remove no-longer-needed static var. * src/systime.h: Include <sys/time.h> on all hosts, not just if WINDOWSNT, since 'struct timeval' is needed in general. (EMACS_TIME): Now a typedef, not a macro. (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants, not macros. (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P) (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ) (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT) (EMACS_TIME_LE): Now functions, not macros. (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS) (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros, which are not functions. All uses rewritten to use: (make_emacs_time): New function. (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME) (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are not functions. All uses rewritten to use the following, respectively: (emacs_secs_addr, invalid_emacs_time, get_emacs_time) (add_emacs_time, sub_emacs_time): New functions. * src/atimer.c: Don't include <sys/time.h>, as "systime.h" does this. * src/fileio.c (Fcopy_file): * src/xterm.c (XTflash): Get the current time closer to when it's used. * src/makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
2012-07-10Optimize pure C strings initialization.Dmitry Antipov
* lisp.h (make_pure_string): Fix prototype. (build_pure_c_string): New function, defined as static inline. This provides a better opportunity to optimize away calls to strlen when the function is called with compile-time constant argument. * alloc.c (make_pure_c_string): Fix comment. Change to add nchars argument, adjust users accordingly. Use build_pure_c_string where appropriate. * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c, * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c, * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

2012-05-23Fix bug #11519 with relocation of buffer text during regex search.Eli Zaretskii
src/lisp.h [REL_ALLOC]: Add prototypes for external functions defined on ralloc.c. src/buffer.c [REL_ALLOC]: Remove prototypes of r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free, they are now on lisp.h. src/ralloc.c (r_alloc_inhibit_buffer_relocation): New function. src/search.c (search_buffer): Use it to inhibit relocation of buffer text while re_search_2 is doing its job, because re_search_2 is passed C pointers to buffer text.

2012-04-28Do not avoid creating empty evaporating overlays (Bug#9642).Paul Eggert
* buffer.c (Fmove_overlay): Revert the change of 2012-04-23. That is, do not delete an evaporating overlay if it becomes empty after its bounds are adjusted to fit within its buffer. This fix caused other problems, and I'm reverting it until we get to the bottom of them.
2012-04-23Do not create empty overlays with the evaporate property (Bug#9642).Paul Eggert
* buffer.c (Fmove_overlay): Delete an evaporating overlay if it becomes empty after its bounds are adjusted to fit within its buffer. Without this fix, in a nonempty buffer (let ((o (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1)) yields an empty overlay that has the evaporate property, which is not supposed to happen.
