-------------------- ChangeLog entries follow: --------------------
lisp/ChangeLog addition:
2010-02-01 Ben Wing <ben@xemacs.org>
* cl-extra.el:
* cl-extra.el (cl-string-vector-equalp): Removed.
* cl-extra.el (cl-bit-vector-vector-equalp): Removed.
* cl-extra.el (cl-vector-array-equalp): Removed.
* cl-extra.el (cl-hash-table-contents-equalp): Removed.
* cl-extra.el (equalp): Removed.
* cl-extra.el (cl-mapcar-many):
Comment out the whole `equalp' implementation for the moment;
remove once we're sure the C implementation works.
* cl-macs.el:
* cl-macs.el (equalp):
Simplify the compiler-macro for `equalp' -- once it's in C,
we don't need to try so hard to expand it.

* opaque.c (equal_opaque):
* opaque.c (equal_opaque_ptr):
* rangetab.c (range_table_equal):
* specifier.c (specifier_equal):
Add a `foldcase' param to the equal() method and use it to implement
`equalp' comparisons. Also add to plists_differ(), although we
don't currently use it here.
Rewrite internal_equalp(). Implement cross-type vector comparisons.
Don't implement our own handling of numeric promotion -- just use
the `=' primitive.
Add internal_equal_0(), which takes a `foldcase' param and calls
either internal_equal() or internal_equalp().
* buffer.h:
When given a 0 for buffer (which is the norm when functions don't
have a specific buffer available), use the current buffer's table,
not `standard-case-table'; otherwise the current settings are
ignored.
* casetab.c:
* casetab.c (set_case_table):
When handling old-style vectors of 256 in `set-case-table' don't
overwrite the existing table! Instead create a new table and
populate.
* device-msw.c (sync_printer_with_devmode):
* lisp.h:
* text.c (lisp_strcasecmp_ascii):
Rename lisp_strcasecmp to lisp_strcasecmp_ascii and use
lisp_strcasecmp_i18n for caseless comparisons in some places.

Delete unused lisp_string_hash and lisp_string_equal().
* events.h:
* keymap-buttons.h:

* keymap.c (INCLUDE_BUTTON_ZERO):
New file keymap-buttons.h; use to handle buttons 1-26 in place of
duplicating code 26 times.
* frame-gtk.c (allocate_gtk_frame_struct):
* frame-msw.c (mswindows_init_frame_1):
Fix some comments about internal_equal() in redisplay that don't
apply any more.
* keymap-slots.h:
* keymap.c:
New file keymap-slots.h. Use it to notate the slots in a keymap
structure, similar to frameslots.h or coding-system-slots.h.
* keymap.c (MARKED_SLOT):
* keymap.c (keymap_equal):
* keymap.c (keymap_hash):
Implement.
tests/ChangeLog addition:
2010-02-01 Ben Wing <ben@xemacs.org>
* automated/case-tests.el:
* automated/case-tests.el (uni-mappings):
* automated/search-tests.el:
Delete old pristine-case-table code. Rewrite the Unicode torture
test to take into account whether overlapping mappings exist for
more than one character, and not doing the upcase/downcase
comparisons in such cases.
* automated/lisp-tests.el (foo):
* automated/lisp-tests.el (string-variable):
* automated/lisp-tests.el (featurep):
Replace Assert (equal ... with Assert-equal; same for other types
of equality. Replace some awkward equivalents of Assert-equalp
with Assert-equalp. Add lots of equalp tests.
* automated/case-tests.el:
* automated/regexp-tests.el:
* automated/search-tests.el:
Fix up the comments at the top of the files. Move rules about where
to put tests into case-tests.el.
* automated/test-harness.el:
* automated/test-harness.el (test-harness-aborted-summary-template): New.
* automated/test-harness.el (test-harness-from-buffer):
* automated/test-harness.el (batch-test-emacs):
Fix Assert-test-not. Create Assert-not-equal and variants.
Delete the doc strings from all these convenience functions to avoid
excessive repetition; instead use one copy in a comment.

| 428 | 1 This directory contains the source files for the C component of XEmacs. |
| 2 Nothing in this directory is needed for using XEmacs once it is built | |
| 3 and installed, if the dumped Emacs is copied elsewhere. | |
| 4 | |
| 5 See the files ../README and then ../INSTALL for installation instructions. | |
| 6 | |
| 7 Under Unix, the file `Makefile.in.in' is used as a template by the script | |
| 8 `../configure' to produce `Makefile.in'. The same script then uses `cpp' | |
| 9 to produce the machine-dependent `Makefile' from `Makefile.in'; | |
| 10 `Makefile' is the file which actually controls the compilation of | |
| 11 Emacs. Most of this should work transparently to the user; you should | |
| 12 only need to run `../configure', and then type `make'. | |
| 13 | |
| 14 General changes for XEmacs: | |
| 15 --------------------------- | |
| 16 1. Lisp objects. | |
| 17 | |
| 18 -- XFASTINT has been eliminated. Use of this expression as an lvalue | |
| 19 is incompatible with the union form of Lisp objects, and use as | |
| 20 an rvalue is likely to lead to errors and doesn't really save much | |
| 21 time. Expressions of the form `XFASTINT (obj) = num;' get replaced | |
| 22 by `obj = make_int (num);' or `XSETINT (obj, num);' and | |
| 23 expressions of the form `num = XFASTINT (obj);' get replaced by | |
| 24 `num = XINT (obj);'. Use Qzero in place of `make_int (0)'. | |
| 25 | |
| 26 -- Use of XTYPE gets replaced by the appropriate predicate. Using | |
| 27 XTYPE only works for the small number of types that are not stored | |
| 28 using the Lisp_Record type (int, cons, string, and vector). For | |
| 29 example, `(XTYPE (foo) == Lisp_Buffer)' gets replaced by | |
| 30 `(BUFFERP (foo))'. | |
| 31 | |
| 32 -- `XSET (obj, Lisp_Int, num)' gets replaced by `XSETINT (obj, num)', | |
| 33 for consistency. | |
| 34 | |
| 35 -- Some occurrences of XSET need to get replaced by XSETR -- | |
| 36 specifically, those where the type is not a primitive type | |
| 37 (primitive types are int, cons, string, and vector). | |
| 38 | |
| 39 -- References to `XSTRING (obj)->size' get replaced with | |
| 40 `XSTRING_LENGTH (obj)'. This is currently for cosmetic reasons | |
| 41 but there may be other reasons in the future. (This change is | |
| 42 currently incomplete in the source files.) | |
| 43 | |
| 44 | |
| 45 2. Storage classes: | |
| 46 | |
| 47 -- All occurrences of `register' should be replaced by `REGISTER'. | |
| 48 It interferes with backtraces so we disable it if DEBUG_XEMACS | |
| 49 is defined. | |
| 50 | |
| 51 | |
| 52 3. Errors, messages, I18N3 snarfing: | |
| 53 | |
| 54 -- Errors are continuable in XEmacs but are not in FSF Emacs. | |
| 55 Therefore, it's important that functions do something reasonable | |
| 56 if an error gets continued. If you want to signal a non- | |
| 57 continuable error, the call to Fsignal() gets put inside a | |
| 58 `while (1)' loop. To facilitate this, and also for proper I18N3 | |
| 59 message snarfing, most calls to Fsignal() have been replaced by | |
| 60 calls to signal_error(), signal_simple_error(), etc. Look at | |
| 61 eval.c for a classification of various error functions. | |
| 62 | |
| 63 -- Constant strings occurring in source files need to get wrapped | |
| 64 in a call to GETTEXT (or if inside of a call to `build_string', | |
| 65 change that function to `build_translated_string') if they don't | |
| 66 occur in certain places where the I18N3 message snarfer will see | |
| 67 them. For a complete discussion of this, see the file | |
| 68 lib-src/make-msgfile.lex. | |
| 69 | |
| 70 NOTE: I18N3 support is not currently working, so the above may | |
| 71 or may not apply. Thus it is not a good idea to add random | |
| 72 GETTEXTs, unless you really know what you are doing. | |
| 73 | |
| 74 -- Calls to `fprintf (stderr, ...)' and `printf (...)' get replaced | |
| 75 with calls to `stderr_out' and `stdout_out'. This is for I18N3 | |
| 76 message snarfing. | |
| 77 | |
| 78 4. Initialization: | |
| 79 | |
| 80 -- FSF constructs like `obj = intern ("string"); staticpro (&obj);' | |
| 81 get replaced by `defsymbol (&obj);'. This is for code cleanness | |
| 82 and better purespace usage. | |
| 83 -- FSF constructs like | |
| 84 obj = intern ("error"); | |
| 85 Fput (obj, Qerror_message, "message"); | |
| 86 Fput (obj, Qerror_conditions, some list); | |
| 87 get replaced by calls to deferror(). See the definition of | |
| 88 deferror() for how the correct arguments to pass. This is for | |
| 89 code cleanness and I18N3 message snarfing. | |
| 90 -- Code in keys_of_foo() functions has been moved into Lisp. |
