cleanups to debug-print, try harder to make it work during GC
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-08 Ben Wing <ben@xemacs.org>
* emacs.c:
* emacs.c (assert_failed):
Fix comments about when inhibit_non_essential_printing_operations
is set and how used. Increment/decrement in assert_failed rather
than just setting/resetting to avoid hosing things in case we're
called when the value is already non-zero. Similarly increment/
decrement in_assert_failed.
* gc.c (gc_prepare):
* gc.c (gc_finish):
Increment/decrement inhibit_non_essential_printing_operations
rather than setting/resetting.
* print.c:
* print.c (debug_out):
* print.c (write_string_to_alternate_debugging_output):
* print.c (restore_inhibit_non_essential_conversion_operations):
* print.c (debug_print_exit):
* print.c (debug_print_enter):
* print.c (debug_prin1):
* print.c (debug_p4):
* print.c (ext_print_begin):
* print.c (ext_print_end):
* print.c (external_debug_print):
* print.c (debug_p3):
* print.c (debug_backtrace):
* print.c (debug_short_backtrace):
* print.c (vars_of_print):
Lots of cleanup. Fix debug_out() so it binds
inhibit_non_essential_printing_operations around it to ensure no
conversion. Remove many other places that set the same var since
the lower-level functions now all do it. A few other places, add
inhibit_non_essential_printing_operations bindings.Extract the
code out that sets up and resets lots of bindings in debug_prin1()
so that debug_backtrace() can use it, and rewrite it to use the
new STORE_VOID_IN_LISP() rather than having to have a single
static opaque structure holding all the bindings (and not handling
reentrancy). Fix raw `char' to be `CIbyte' in the declaration of
`alternate_do_string'.
* signal.c (check_what_happened):
Fix bug: Don't try to check for QUIT when
inhibit_non_essential_printing_operations or we may screw things
up if QUIT happens during debug printing.

This file exists only because VC++ lacks pragmas that let you change the default calling convention in the middle of a file. With optimization, we compile XEmacs using fastcall as the default convention; but libraries are not compiled this way, and thus need __cdecl in their declaration. Without the pragma, we either (a) depend on libraries that declare their external functions with suitable preprocessor definitions that we can change; (b) force the user to recompile the library with fastcall (not reasonable); (c) hack the headers manually (not reasonable); (d) put all calls to the library in a separate file where the default calling convention is __cdecl (hence, this file). In fact, some libraries do make (a) feasible. This is the case with PNG and ZLIB. JPEG almost does so, since all externs are wrapped with EXTERN(); but they fail to wrap their definition of EXTERN with #ifndef EXTERN, so we can't override it. XPM is similar, wrapping their externs with FUNC() -- again, not overridable. With PNG, we define PNG_EXPORT; with ZLIB, we define ZEXPORT and ZEXPORTVA. */ #ifdef HAVE_XPM void qxe_XpmFreeXpmImage (XpmImage *image) { XpmFreeXpmImage (image); } void qxe_XpmFreeXpmInfo (XpmInfo *info) { XpmFreeXpmInfo (info); } int qxe_XpmCreateXpmImageFromBuffer (char *buffer, XpmImage *image, XpmInfo *info) { return XpmCreateXpmImageFromBuffer (buffer, image, info); } void qxe_XpmFree (void *ptr) { XpmFree (ptr); } int qxe_XpmReadFileToData (char *filename, char ***data_return) { return XpmReadFileToData (filename, data_return); } #endif /* HAVE_XPM */ #ifdef HAVE_JPEG boolean qxe_jpeg_finish_decompress (j_decompress_ptr cinfo) { return jpeg_finish_decompress (cinfo); } boolean qxe_jpeg_start_decompress (j_decompress_ptr cinfo) { return jpeg_start_decompress (cinfo); } JDIMENSION qxe_jpeg_read_scanlines (j_decompress_ptr cinfo, JSAMPARRAY scanlines, JDIMENSION max_lines) { return jpeg_read_scanlines (cinfo, scanlines, max_lines); } int qxe_jpeg_read_header (j_decompress_ptr cinfo, boolean require_image) { return jpeg_read_header (cinfo, require_image); } void qxe_jpeg_CreateDecompress (j_decompress_ptr cinfo, int version, size_t structsize) { jpeg_CreateDecompress (cinfo, version, structsize); } struct jpeg_error_mgr * qxe_jpeg_std_error (struct jpeg_error_mgr *err) { return jpeg_std_error (err); } void qxe_jpeg_destroy_decompress (j_decompress_ptr cinfo) { jpeg_destroy_decompress (cinfo); } boolean qxe_jpeg_resync_to_restart (j_decompress_ptr cinfo, int desired) { return jpeg_resync_to_restart (cinfo, desired); } #endif /* HAVE_JPEG */ #ifdef HAVE_TIFF tdata_t qxe_TIFFmalloc (tsize_t x1) { return _TIFFmalloc (x1); } void qxe_TIFFfree (tdata_t x1) { _TIFFfree (x1); } void qxe_TIFFClose (TIFF *x1) { TIFFClose (x1); } int qxe_TIFFGetField (TIFF *x1, ttag_t x2, uint32 *x3) { return TIFFGetField (x1, x2, x3); } TIFF * qxe_TIFFClientOpen (const char *x1, const char *x2, thandle_t x3, TIFFReadWriteProc x4, TIFFReadWriteProc x5, TIFFSeekProc x6, TIFFCloseProc x7, TIFFSizeProc x8, TIFFMapFileProc x9, TIFFUnmapFileProc x10) { return TIFFClientOpen (x1, x2, x3, x4, x5, x6, x7, x8, x9, x10); } TIFFErrorHandler qxe_TIFFSetErrorHandler (TIFFErrorHandler x1) { return TIFFSetErrorHandler (x1); } TIFFErrorHandler qxe_TIFFSetWarningHandler (TIFFErrorHandler x1) { return TIFFSetWarningHandler (x1); } int qxe_TIFFReadRGBAImage (TIFF *x1, uint32 x2, uint32 x3, uint32 *x4, int x5) { return TIFFReadRGBAImage (x1, x2, x3, x4, x5); } #endif /* HAVE_TIFF */
