[xemacs-hg @ 2004-11-04 23:05:23 by ben] commit mega-patch configure.in: Turn off -Winline and -Wchar-subscripts. Use the right set of cflags when compiling modules. Rewrite ldap configuration to separate the inclusion of lber (needed in recent Cygwin) from the basic checks for the needed libraries. add a function for MAKE_JUNK_C; initially code was added to generate xemacs.def using this, but it will need to be rewritten. add an rm -f for junk.c to avoid weird Cygwin bug with cp -f onto an existing file. Sort list of auto-detected functions and eliminate unused checks for stpcpy, setlocale and getwd. Add autodetection of Cygwin scanf problems BETA: Rewrite section on configure to indicate what flags are important and what not. digest-doc.c, make-dump-id.c, profile.c, sorted-doc.c: Add proper decls for main(). make-msgfile.c: Document that this is old junk. Move proposal to text.c. make-msgfile.lex: Move proposal to text.c. make-mswin-unicode.pl: Convert error-generating code so that the entire message will be seen as a single unrecognized token. mule/mule-ccl.el: Update docs. lispref/mule.texi: Update CCL docs. ldap/eldap.c: Mule-ize. Use EXTERNAL_LIST_LOOP_2 instead of deleted EXTERNAL_LIST_LOOP. * XEmacs 21.5.18 "chestnut" is released. --------------------------------------------------------------- MULE-RELATED WORK: --------------------------------------------------------------- --------------------------- byte-char conversion --------------------------- buffer.c, buffer.h, insdel.c, text.c: Port FSF algorithm for byte-char conversion, replacing broken previous version. Track the char position of the gap. Add functions to do char-byte conversion downwards as well as upwards. Move comments about algorithm workings to internals manual. --------------------------- work on types --------------------------- alloc.c, console-x-impl.h, dump-data.c, dump-data.h, dumper.c, dialog-msw.c, dired-msw.c, doc.c, editfns.c, esd.c, event-gtk.h, event-msw.c, events.c, file-coding.c, file-coding.h, fns.c, glyphs-eimage.c, glyphs-gtk.c, glyphs-msw.c, glyphs-shared.c, glyphs-x.c, glyphs.c, glyphs.h, gui.c, hpplay.c, imgproc.c, intl-win32.c, lrecord.h, lstream.c, keymap.c, lisp.h, libsst.c, linuxplay.c, miscplay.c, miscplay.h, mule-coding.c, nas.c, nt.c, ntheap.c, ntplay.c, objects-msw.c, objects-tty.c, objects-x.c, print.c, process-nt.c, process.c, redisplay.h, select-common.h, select-gtk.c, select-x.c, sgiplay.c, sound.c, sound.h, sunplay.c, sysfile.h, sysdep.c, syswindows.h, text.c, unexnt.c, win32.c, xgccache.c: Further work on types. This creates a full set of types for all the basic semantics of `char' that I have so far identified, so that its semantics can always be identified for the purposes of proper Mule-safe code, and the raw use of `char' always avoided. (1) More type renaming, for consistency of naming. Char_ASCII -> Ascbyte UChar_ASCII -> UAscbyte Char_Binary -> CBinbyte UChar_Binary -> Binbyte SChar_Binary -> SBinbyte (2) Introduce Rawbyte, CRawbyte, Boolbyte, Chbyte, UChbyte, and Bitbyte and use them. (3) New types Itext, Wexttext and Textcount for separating out the concepts of bytes and textual units (different under UTF-16 and UTF-32, which are potential internal encodings). (4) qxestr*_c -> qxestr*_ascii. lisp.h: New; goes with other qxe() functions. #### Maybe goes in a different section. lisp.h: Group generic int-type defs together with EMACS_INT defs. lisp.h: * lisp.h (WEXTTEXT_IS_WIDE) New defns. lisp.h: New type to replace places where int occurs as a boolean. It's signed because occasionally people may want to use -1 as an error value, and because unsigned ints are viral -- see comments in the internals manual against using them. dynarr.c: int -> Bytecount. --------------------------- Mule-izing --------------------------- device-x.c: Partially Mule-ize. dumper.c, dumper.h: Mule-ize. Use Rawbyte. Use stderr_out not printf. Use wext_*(). sysdep.c, syswindows.h, text.c: New Wexttext API for manipulation of external text that may be Unicode (e.g. startup code under Windows). emacs.c: Mule-ize. Properly deal with argv in external encoding. Use wext_*() and Wexttext. Use Rawbyte. #if 0 some old junk on SCO that is unlikely to be correct. Rewrite allocation code in run-temacs. emacs.c, symsinit.h, win32.c: Rename win32 init function and call it even earlier, to initialize mswindows_9x_p even earlier, for use in startup code (XEUNICODE_P). process.c: Use _wenviron not environ under Windows, to get Unicode environment variables. event-Xt.c: Mule-ize drag-n-drop related stuff. dragdrop.c, dragdrop.h, frame-x.c: Mule-ize. text.h: Add some more stand-in defines for particular kinds of conversion; use in Mule-ization work in frame-x.c etc. --------------------------- Freshening --------------------------- intl-auto-encap-win32.c, intl-auto-encap-win32.h: Regenerate. --------------------------- Unicode-work --------------------------- intl-win32.c, syswindows.h: Factor out common options to MultiByteToWideChar and WideCharToMultiByte. Add convert_unicode_to_multibyte_malloc() and convert_unicode_to_multibyte_dynarr() and use. Add stuff for alloca() conversion of multibyte/unicode. alloc.c: Use dfc_external_data_len() in case of unicode coding system. alloc.c, mule-charset.c: Don't zero out and reinit charset Unicode tables. This fucks up dump-time loading. Anyway, either we load them at dump time or run time, never both. unicode.c: Dump the blank tables as well. --------------------------------------------------------------- DOCUMENTATION, MOSTLY MULE-RELATED: --------------------------------------------------------------- EmacsFrame.c, emodules.c, event-Xt.c, fileio.c, input-method-xlib.c, mule-wnnfns.c, redisplay-gtk.c, redisplay-tty.c, redisplay-x.c, regex.c, sysdep.c: Add comment about Mule work needed. text.h: Add more documentation describing why DFC routines were not written to return their value. Add some other DFC documentation. console-msw.c, console-msw.h: Add pointer to docs in win32.c. emacs.c: Add comments on sources of doc info. text.c, charset.h, unicode.c, intl-win32.c, intl-encap-win32.c, text.h, file-coding.c, mule-coding.c: Collect background comments and related to text matters and internationalization, and proposals for work to be done, in text.c or Internals manual, stuff related to specific textual API's in text.h, and stuff related to internal implementation of Unicode conversion in unicode.c. Put lots of pointers to the comments to make them easier to find. s/mingw32.h, s/win32-common.h, s/win32-native.h, s/windowsnt.h, win32.c: Add bunches of new documentation on the different kinds of builds and environments under Windows and how they work. Collect this info in win32.c. Add pointers to these docs in the relevant s/* files. emacs.c: Document places with long comments. Remove comment about exiting, move to internals manual, put in pointer. event-stream.c: Move docs about event queues and focus to internals manual, put in pointer. events.h: Move docs about event stream callbacks to internals manual, put in pointer. profile.c, redisplay.c, signal.c: Move documentation to the Internals manual. process-nt.c: Add pointer to comment in win32-native.el. lisp.h: Add comments about some comment conventions. lisp.h: Add comment about the second argument. device-msw.c, redisplay-msw.c: @@#### comments are out-of-date. --------------------------------------------------------------- PDUMP WORK (MOTIVATED BY UNICODE CHANGES) --------------------------------------------------------------- alloc.c, buffer.c, bytecode.c, console-impl.h, console.c, device.c, dumper.c, lrecord.h, elhash.c, emodules.h, events.c, extents.c, frame.c, glyphs.c, glyphs.h, mule-charset.c, mule-coding.c, objects.c, profile.c, rangetab.c, redisplay.c, specifier.c, specifier.h, window.c, lstream.c, file-coding.h, file-coding.c: PDUMP: Properly implement dump_add_root_block(), which never worked before, and is necessary for dumping Unicode tables. Pdump name changes for accuracy: XD_STRUCT_PTR -> XD_BLOCK_PTR. XD_STRUCT_ARRAY -> XD_BLOCK_ARRAY. XD_C_STRING -> XD_ASCII_STRING. *_structure_* -> *_block_*. lrecord.h: some comments added about dump_add_root_block() vs dump_add_root_block_ptr(). extents.c: remove incorrect comment about pdump problems with gap array. --------------------------------------------------------------- ALLOCATION --------------------------------------------------------------- abbrev.c, alloc.c, bytecode.c, casefiddle.c, device-msw.c, device-x.c, dired-msw.c, doc.c, doprnt.c, dragdrop.c, editfns.c, emodules.c, file-coding.c, fileio.c, filelock.c, fns.c, glyphs-eimage.c, glyphs-gtk.c, glyphs-msw.c, glyphs-x.c, gui-msw.c, gui-x.c, imgproc.c, intl-win32.c, lread.c, menubar-gtk.c, menubar.c, nt.c, objects-msw.c, objects-x.c, print.c, process-nt.c, process-unix.c, process.c, realpath.c, redisplay.c, search.c, select-common.c, symbols.c, sysdep.c, syswindows.h, text.c, text.h, ui-byhand.c: New macros {alloca,xnew}_{itext,{i,ext,raw,bin,asc}bytes} for more convenient allocation of these commonly requested items.

 #include "systime.h"
 
-/* There is one object called an event_stream.  This object contains
-   callback functions for doing the window-system-dependent operations
-   that XEmacs requires.
-
-   If XEmacs is compiled with support for X11 and the X Toolkit, then this
-   event_stream structure will contain functions that can cope with input
-   on XEmacs windows on multiple displays, as well as input from dumb tty
-   frames.
-
-   If it is desired to have XEmacs able to open frames on the displays of
-   multiple heterogeneous machines, X11 and SunView, or X11 and NeXT, for
-   example, then it will be necessary to construct an event_stream structure
-   that can cope with the given types.  Currently, the only implemented
-   event_streams are for dumb-ttys, and for X11 plus dumb-ttys,
-   and for mswindows.
-
-   To implement this for one window system is relatively simple.
-   To implement this for multiple window systems is trickier and may
-   not be possible in all situations, but it's been done for X and TTY.
-
-   Note that these callbacks are *NOT* console methods; that's because
-   the routines are not specific to a particular console type but must
-   be able to simultaneously cope with all allowable console types.
-
-  The slots of the event_stream structure:
-
- next_event_cb		A function which fills in an XEmacs_event structure
-			with the next event available.  If there is no event
-			available, then this should block.
-
-			IMPORTANT: timer events and especially process
-			events *must not* be returned if there are
-			events of other types available; otherwise you
-			can end up with an infinite loop in Fdiscard_input().
+/*
 
- event_pending_cb	A function which says whether there are events to be
-			read.  If called with an argument of 0, then this
-			should say whether calling the next_event_cb will
-			block.  If called with a non-zero argument, then this
-			should say whether there are that many user-generated
-			events pending (that is, keypresses, mouse-clicks,
-			dialog-box selection events, etc.). (This is used for
-			redisplay optimization, among other things.)  The
-			difference is that the former includes process events
-			and timer events, but the latter doesn't.
-
-			If this function is not sure whether there are events
-			to be read, it *must* return 0.  Otherwise various
-			undesirable effects will occur, such as redisplay
-			not occurring until the next event occurs.
-
- handle_magic_event_cb	XEmacs calls this with an event structure which
-  			contains window-system dependent information that
-			XEmacs doesn't need to know about, but which must
-			happen in order.  If the next_event_cb never returns
-			an event of type "magic", this will never be used.
-
- format_magic_event_cb  Called with a magic event; print a representation of
-                        the innards of the event to PSTREAM.
-                        
- compare_magic_event_cb Called with two magic events; return non-zero if
-                        the innards of the two are equal, zero otherwise.
-
- hash_magic_event_cb    Called with a magic event; return a hash of the
-                        innards of the event.
-
- add_timeout_cb		Called with an EMACS_TIME, the absolute time at
-			which a wakeup event should be generated; and a
-			void *, which is an arbitrary value that will be
-			returned in the timeout event.  The timeouts
-			generated by this function should be one-shots:
-			they fire once and then disappear.  This callback
-			should return an int id-number which uniquely
-			identifies this wakeup.  If an implementation
-			doesn't have microseconds or millisecond
-			granularity, it should round up to the closest
-			value it can deal with.
+See also
 
- remove_timeout_cb	Called with an int, the id number of a wakeup to
- 			discard.  This id number must have been returned by
-			the add_timeout_cb.  If the given wakeup has
-			already expired, this should do nothing.
-
- select_process_cb	These callbacks tell the underlying implementation to
- unselect_process_cb	add or remove a file descriptor from the list of fds
-  			which are polled for inferior-process input.  When
-			input becomes available on the given process
-			connection, an event of type "process" should be
-			generated.
-
- select_console_cb	These callbacks tell the underlying implementation
- unselect_console_cb	to add or remove a console from the list of consoles
-                        which are polled for user-input.
-
- select_device_cb	These callbacks are used by Unixoid event loops
- unselect_device_cb	(those that use select() and file descriptors and
-			have a separate input fd per device).
-
- create_io_streams_cb   These callbacks are called by process code to
- delete_io_streams_cb   create the input and output lstreams which are used
-                        for subprocess I/O.
-
- quitp_cb		A handler function called from the `QUIT' macro which
-			should check whether the quit character has been
-			typed.  On systems with SIGIO, this will not be called
-			unless the `sigio_happened' flag is true (it is set
-			from the SIGIO handler).
-
- XEmacs has its own event structures, which are distinct from the event
- structures used by X or any other window system.  It is the job of the
- event_stream layer to translate to this format.

-  Stream pairs description
-  ------------------------
+  (Info-goto-node "(internals)Event Stream Callback Routines")
+  (Info-goto-node "(internals)Stream Pairs")
 
-  Since there are many possible processes/event loop combinations, the
-  event code is responsible for creating an appropriate lstream type. The
-  process implementation does not care about that implementation.
-
-  The Create stream pair function is passed two void* values, which
-  identify process-dependent 'handles'. The process implementation uses
-  these handles to communicate with child processes. The function must be
-  prepared to receive handle types of any process implementation. Since
-  only one process implementation exists in a particular XEmacs
-  configuration, preprocessing is a means of compiling in the support for
-  the code which deals with particular handle types.
-
-  For example, a unixoid type loop, which relies on file descriptors, may be
-  asked to create a pair of streams by a unix-style process implementation.
-  In this case, the handles passed are unix file descriptors, and the code
-  may deal with these directly. Although, the same code may be used on Win32
-  system with X-Windows. In this case, Win32 process implementation passes
-  handles of type HANDLE, and the create_io_streams function must call
-  appropriate function to get file descriptors given HANDLEs, so that these
-  descriptors may be passed to XtAddInput.
-
-  The handle given may have special denying value, in which case the
-  corresponding lstream should not be created.
-
-  The return value of the function is a unique stream identifier. It is used
-  by processes implementation, in its  platform-independent part. There is
-  the get_process_from_usid function, which returns process object given its
-  USID. The event stream is responsible for converting its internal handle
-  type into USID.
-
-  Example is the TTY event stream. When a file descriptor signals input, the
-  event loop must determine process to which the input is destined. Thus,
-  the implementation uses process input stream file descriptor as USID, by
-  simply casting the fd value to USID type.
-
-  There are two special USID values. One, USID_ERROR, indicates that the stream
-  pair cannot be created. The second, USID_DONTHASH, indicates that streams are
-  created, but the event stream does not wish to be able to find the process
-  by its USID. Specifically, if an event stream implementation never calls
-  get_process_from_usid, this value should always be returned, to prevent
-  accumulating useless information on USID to process relationship.
