* gc.c (register_for_finalization):
* gc.c (mark_object):
* gc.h:
* lisp.h:
* profile.c:
* profile.c (mark_profiling_info_maphash):
Clean up KKCC code related to DEBUG_XEMACS. Rename
kkcc_backtrace() to kkcc_backtrace_1() and add two params: a
`size' arg to control how many stack elements to print and a
`detailed' arg to control whether Lisp objects are printed using
`debug_print()'. Create front-ends to kkcc_backtrace_1() --
kkcc_detailed_backtrace(), kkcc_short_backtrace(),
kkcc_detailed_backtrace_full(), kkcc_short_backtrace_full(), as
well as shortened versions kbt(), kbts(), kbtf(), kbtsf() -- to
call it with various parameter values. Add an `is_lisp' field to
the stack and backtrace structures and use it to keep track of
whether an object pushed onto the stack is a Lisp object or a
non-Lisp structure; in kkcc_backtrace_1(), don't try to print a
non-Lisp structure as a Lisp object.
* elhash.c:
* extents.c:
* file-coding.c:
* lrecord.h:
* lrecord.h (IF_NEW_GC):
* marker.c:
* marker.c (Fmarker_buffer):
* mule-coding.c:
* number.c:
* rangetab.c:
* specifier.c:
New macros IF_OLD_GC(), IF_NEW_GC() to simplify declaration of
Lisp objects when a finalizer may exist in one but not the other.
Use them appropriately.
* extents.c (finalize_extent_info):
Don't zero out data->soe and data->extents before trying to free,
else we get memory leaks.
* lrecord.h (enum lrecord_type):
Make the first lrecord type have value 1 not 0 so that 0 remains
without implementation and attempts to interpret zeroed memory
as a Lisp object will be more obvious.
* array.c (Dynarr_free):
* device-msw.c (msprinter_delete_device):
* device-tty.c (free_tty_device_struct):
* device-tty.c (tty_delete_device):
* dialog-msw.c (handle_directory_dialog_box):
* dialog-x.c:
* emacs.c (free_argc_argv):
* emodules.c (attempt_module_delete):
* file-coding.c (chain_finalize_coding_stream_1):
* file-coding.c (chain_finalize_coding_stream):
* glyphs-eimage.c:
* glyphs-eimage.c (jpeg_instantiate_unwind):
* glyphs-eimage.c (gif_instantiate_unwind):
* glyphs-eimage.c (png_instantiate_unwind):
* glyphs-eimage.c (tiff_instantiate_unwind):
* imgproc.c:
* imgproc.c (build_EImage_quantable):
* insdel.c (uninit_buffer_text):
* mule-coding.c (iso2022_finalize_detection_state):
* objects-tty.c (tty_finalize_color_instance):
* objects-tty.c (tty_finalize_font_instance):
* objects-tty.c (tty_font_list):
* process.c:
* process.c (finalize_process):
* redisplay.c (add_propagation_runes):
* scrollbar-gtk.c:
* scrollbar-gtk.c (gtk_free_scrollbar_instance):
* scrollbar-gtk.c (gtk_release_scrollbar_instance):
* scrollbar-msw.c:
* scrollbar-msw.c (mswindows_free_scrollbar_instance):
* scrollbar-msw.c (unshow_that_mofo):
* scrollbar-x.c (x_free_scrollbar_instance):
* scrollbar-x.c (x_release_scrollbar_instance):
* select-x.c:
* select-x.c (x_handle_selection_request):
* syntax.c:
* syntax.c (uninit_buffer_syntax_cache):
* text.h (eifree):
If possible, whenever we call xfree() on a field in a structure,
set the field to 0 afterwards. A lot of code is written so that
it checks the value being freed to see if it is non-zero before
freeing it -- doing this and setting the value to 0 afterwards
ensures (a) we won't try to free twice if the cleanup code is
called twice; (b) if the object itself stays around, KKCC won't
crash when attempting to mark the freed field.
* rangetab.c:
Add a finalization method when not NEW_GC to avoid memory leaks.
(#### We still get memory leaks when NEW_GC; need to convert gap
array to Lisp object).

| 37 -- A time line for Lucid Emacs/XEmacs is | |
| 38 | |
| 2517 | 39 Version 19.0 shipped with Energize 1.0, April 1992. |
| 40 Version 19.1 released June 4, 1992. | |
| 41 Version 19.2 released June 19, 1992. | |
| 42 Version 19.3 released September 9, 1992. | |
| 43 Version 19.4 released January 21, 1993. | |
| 44 Version 19.5 released February 5, 1993. This was a repackaging of 19.4 with a | |
| 45 few bug fixes and shipped with Energize 2.0. It was a trade-show giveaway | |
| 46 and never released to the net. | |
| 47 Version 19.6 released April 9, 1993. | |
| 48 Version 19.7 was a repackaging of 19.6 with a few bug fixes and | |
| 442 | 49 shipped with Energize 2.1. Never released to the net. |
| 2517 | 50 Version 19.8 released September 6, 1993. (Epoch merger, preliminary I18N |
| 51 support) | |
| 52 Version 19.9 released January 12, 1994. (Scrollbars, Athena.) | |
| 53 Version 19.10 released May 27, 1994. Known as "Lucid Emacs" when | |
| 54 shipped by Lucid, and as "XEmacs" when shipped by Sun; but Lucid | |
| 55 went out of business a few days later and it's unclear very many | |
| 56 copies of 19.10 were released by Lucid. (Last release by Jamie Zawinski.) | |
| 57 Version 19.11 (first XEmacs) released September 13, 1994. | |
| 58 Version 19.12 released June 23, 1995. | |
| 59 Version 19.13 released September 1, 1995. | |
| 60 Version 19.14 released June 23, 1996. | |
| 61 Version 20.0 released February 9, 1997. | |
| 62 Version 19.15 released March 28, 1997. | |
| 63 Version 20.1 (not released to the net) April 15, 1997. | |
| 64 Version 20.2 released May 16, 1997. | |
| 65 Version 19.16 released October 31, 1997; retiring of v19 series. | |
| 66 Version 20.3 (the first stable version of XEmacs 20.x) released November 30, | |
| 67 1997. | |
| 68 Version 20.4 released February 28, 1998. (Jamie claims this version is the | |
| 69 "first reasonably stable release with MULE support" and says that "XEmacs | |
| 70 'core' and 'packages' now packaged separately.") | |
| 71 Version 21.0-pre5 released July 18, 1998. (Jamie says "Numbering scheme goes | |
| 72 wonky due to switch to stable + unstable branches.") | |
| 73 Version 21.0.60 released December 10, 1998. (The version naming scheme was | |
| 74 changed at this point: [a] the second version number is odd for stable | |
| 75 versions, even for beta versions; [b] a third version number is added, | |
| 76 replacing the "beta xxx" ending for beta versions and allowing for | |
| 77 periodic maintenance releases for stable versions. Therefore, 21.0 was | |
| 78 never "officially" released; similarly for 21.2, etc.) | |
| 79 Version 21.0.61 released January 4, 1999. | |
| 80 Version 21.0.63 released February 3, 1999. | |
| 81 Version 21.0.64 released March 1, 1999. | |
| 82 Version 21.0.65 released March 5, 1999. | |
| 83 Version 21.0.66 released March 12, 1999. | |
| 84 Version 21.0.67 released March 25, 1999. | |
| 85 Version 21.1.2 released May 14, 1999; on comp.emacs, May 28. (This is | |
| 788 | 86 the followup to 21.0.67. The second version number was bumped to indicate |
| 87 the beginning of the "stable" series.) | |
| 2517 | 88 Version 21.1.3 released June 26, 1999. |
| 89 Version 21.1.4 released July 8, 1999. | |
| 90 Version 21.1.6 released August 14, 1999. (There was no 21.1.5.) | |
| 91 Version 21.1.7 released September 26, 1999. | |

| 222 GNU Emacs version 15 (15.34) was released sometime in 1984 or 1985 and | |
| 223 shared some code with a version of Emacs written by James Gosling (the | |
| 224 same James Gosling who later created the Java language). | |
| 225 GNU Emacs version 16 (first released version was 16.56) was released on | |
| 226 July 15, 1985. All Gosling code was removed due to potential copyright | |
| 227 problems with the code. | |
| 228 version 16.57: released on September 16, 1985. | |
| 229 versions 16.58, 16.59: released on September 17, 1985. | |
| 230 version 16.60: released on September 19, 1985. These later version 16's | |
| 231 incorporated patches from the net, esp. for getting Emacs to work under | |
| 232 System V. | |
| 233 version 17.36 (first official v17 release) released on December 20, 1985. | |
| 234 Included a TeX-able user manual. First official unpatched version that | |

| 3957 The line above is original. Unfortunately, when an error is tripped | |
| 3958 inside of the handler (e.g. during Fbacktrace()), and the handler for | |
| 3959 the handler is invoked, it correctly notices that something is amiss | |
| 3960 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH, | |
| 3961 which causes the debugger to be invoked debugging the handler code in | |
| 3962 this function -- and WITH THE STACK UNWOUND so that you see main() | |
| 3963 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(), | |
| 3964 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH! | |
| 3965 | |
| 3966 There's some real weirdness going on in the stack handling -- unlike | |
| 3967 in Unix, where further crashes just keep adding to the stack, it seems | |
| 3968 that under the structured-exception-handling, the stack can actually | |
| 3969 bounce back and forth between the full stack at the location of the | |
| 3970 exception and the unwound stack at the place where the __try clause was | |
| 3971 established. I don't completely understand it. What I do know is that | |
| 3972 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of | |
| 3973 aborting execution of the handler and going back to the outer filter | |
| 3974 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is | |
| 3975 hunky-dorey -- your debugger sees a crash at the right location with | |
| 3976 the right stack. | |
| 3977 | |
| 3978 I'm leaving in the trickier Unix-like code in the handler; someone who | |
| 3979 understands better than me how the stack works in these handlers could | |
| 3980 fix it up more. As it is, it works pretty well, so I'm not likely to | |
| 3981 touch it more. --ben | |
