annotate src/emacs.c @ 4792:95b04754ea8c
Make #'equalp more compatible with CL; add a compiler macro, test & doc it.
lisp/ChangeLog addition:
2009-11-08 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (cl-string-vector-equalp)
(cl-bit-vector-vector-equalp, cl-vector-array-equalp)
(cl-hash-table-contents-equalp): New functions, to implement
equalp treating arrays with identical contents as equivalent, as
specified by Common Lisp.
(equalp): Revise this function to implement array equivalence,
and the hash-table equalp behaviour specified by CL.
* cl-macs.el (equalp): Add a compiler macro for this function,
used when one of the arguments is constant, and as such, its type
is known at compile time.
man/ChangeLog addition:
2009-11-08 Aidan Kehoe <kehoea@parhasard.net>
* lispref/objects.texi (Equality Predicates):
Document #'equalp here, as well as #'equal and #'eq.
tests/ChangeLog addition:
2009-12-31 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test much of the functionality of equalp; add a pointer to Paul
Dietz' ANSI test suite for this function, converted to Emacs
Lisp. Not including the tests themselves in XEmacs because who
owns the copyright on the files is unclear and the GCL people
didn't respond to my queries.

| 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. | |

| 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. | |

| 3868 The line above is original. Unfortunately, when an error is tripped | |
| 3869 inside of the handler (e.g. during Fbacktrace()), and the handler for | |
| 3870 the handler is invoked, it correctly notices that something is amiss | |
| 3871 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH, | |
| 3872 which causes the debugger to be invoked debugging the handler code in | |
| 3873 this function -- and WITH THE STACK UNWOUND so that you see main() | |
| 3874 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(), | |
| 3875 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH! | |
| 3876 | |
| 3877 There's some real weirdness going on in the stack handling -- unlike | |
| 3878 in Unix, where further crashes just keep adding to the stack, it seems | |
| 3879 that under the structured-exception-handling, the stack can actually | |
| 3880 bounce back and forth between the full stack at the location of the | |
| 3881 exception and the unwound stack at the place where the __try clause was | |
| 3882 established. I don't completely understand it. What I do know is that | |
| 3883 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of | |
| 3884 aborting execution of the handler and going back to the outer filter | |
| 3885 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is | |
| 3886 hunky-dorey -- your debugger sees a crash at the right location with | |
| 3887 the right stack. | |
| 3888 | |
| 3889 I'm leaving in the trickier Unix-like code in the handler; someone who | |
| 3890 understands better than me how the stack works in these handlers could | |
| 3891 fix it up more. As it is, it works pretty well, so I'm not likely to | |
