Redo memory-usage mechanism, make it general; add way of dynamically
initializing Lisp object types -- OBJECT_HAS_METHOD(), similar to
CONSOLE_HAS_METHOD().
(1) Create OBJECT_HAS_METHOD(), OBJECT_HAS_PROPERTY() etc. for
specifying that a Lisp object type has a particular method or
property. Call such methods with OBJECT_METH, MAYBE_OBJECT_METH,
OBJECT_METH_OR_GIVEN; retrieve properties with OBJECT_PROPERTY.
Methods that formerly required a DEFINE_*GENERAL_LISP_OBJECT() to
specify them (getprop, putprop, remprop, plist, disksave) now
instead use the dynamic-method mechanism. The main benefit of
this is that new methods or properties can be added without
requiring that the declaration statements of all existing methods
be modified. We have to make the `struct lrecord_implementation'
non-const, but I don't think this should have any effect on speed --
the only possible method that's really speed-critical is the
mark method, and we already extract those out into a separate
(non-const) array for increased cache locality.
Object methods need to be reinitialized after pdump, so we put
them in separate functions such as face_objects_create(),
extent_objects_create() and call them appropriately from emacs.c
The only current object property (`memusage_stats_list') that
objects can specify is a Lisp object and gets staticpro()ed so it
only needs to be set during dump time, but because it references
symbols that might not exist in a syms_of_() function, we
initialize it in vars_of_(). There is also an object property
(`num_extra_memusage_stats') that is automatically initialized based
on `memusage_stats_list'; we do that in reinit_vars_of_alloc(),
which is called after all vars_of_() functions are called.
`disksaver' method was renamed `disksave' to correspond with the
name normally given to the function (e.g. disksave_lstream()).
(2) Generalize the memory-usage mechanism in `buffer-memory-usage',
`window-memory-usage', `charset-memory-usage' into an object-type-
specific mechanism called by a single function
`object-memory-usage'. (Former function `object-memory-usage'
renamed to `total-object-memory-usage'). Generalize the mechanism
of different "slices" so that we can have different "classes" of
memory described and different "slices" onto each class; `t'
separates classes, `nil' separates slices. Currently we have
three classes defined: the memory of an object itself,
non-Lisp-object memory associated with the object (e.g. arrays or
dynarrs stored as fields in the object), and Lisp-object memory
associated with the object (other internal Lisp objects stored in
the object). This isn't completely finished yet and we might need
to further separate the "other internal Lisp objects" class into
two classes.
The memory-usage mechanism uses a `struct usage_stats' (renamed
from `struct overhead_stats') to describe a malloc-view onto a set
of allocated memory (listing how much was requested and various
types of overhead) and a more general `struct generic_usage_stats'
(with a `struct usage_stats' in it) to hold all statistics about
object memory. `struct generic_usage_stats' contains an array of
32 Bytecounts, which are statistics of unspecified semantics. The
intention is that individual types declare a corresponding struct
(e.g. `struct window_stats') with the same structure but with
specific fields in place of the array, corresponding to specific
statistics. The number of such statistics is an object property
computed from the list of tags (Lisp symbols describing the
statistics) stored in `memusage_stats_list'. The idea here is to
allow particular object types to customize the number and
semantics of the statistics where completely avoiding consing.
This doesn't matter so much yet, but the intention is to have the
memory usage of all objects computed at the end of GC, at the same
time as other statistics are currently computed. The values for
all statistics for a single type would be added up to compute
aggregate values for all objects of a specific type. To make this
efficient, we can't allow any memory allocation at all.
(3) Create some additional functions for creating lists that
specify the elements directly as args rather than indirectly through
an array: listn() (number of args given), listu() (list terminated
by Qunbound).
(4) Delete a bit of remaining unused C window_config stuff, also
unused lrecord_type_popup_data.

| 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.) | |

| 225 GNU Emacs version 16 (first released version was 16.56) was released on | |

| 3950 The line above is original. Unfortunately, when an error is tripped | |
| 3951 inside of the handler (e.g. during Fbacktrace()), and the handler for | |
| 3952 the handler is invoked, it correctly notices that something is amiss | |
| 3953 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH, | |
| 3954 which causes the debugger to be invoked debugging the handler code in | |
| 3955 this function -- and WITH THE STACK UNWOUND so that you see main() | |
| 3956 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(), | |
| 3957 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH! | |
| 3958 | |
| 3959 There's some real weirdness going on in the stack handling -- unlike | |
| 3960 in Unix, where further crashes just keep adding to the stack, it seems | |
| 3961 that under the structured-exception-handling, the stack can actually | |
| 3962 bounce back and forth between the full stack at the location of the | |
| 3963 exception and the unwound stack at the place where the __try clause was | |
| 3964 established. I don't completely understand it. What I do know is that | |
| 3965 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of | |
| 3966 aborting execution of the handler and going back to the outer filter | |
| 3967 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is | |
| 3968 hunky-dorey -- your debugger sees a crash at the right location with | |
| 3969 the right stack. | |
| 3970 | |
| 3971 I'm leaving in the trickier Unix-like code in the handler; someone who | |
| 3972 understands better than me how the stack works in these handlers could | |
| 3973 fix it up more. As it is, it works pretty well, so I'm not likely to | |
| 3974 touch it more. --ben | |
