Changes to make gdk-pixbuf threadsafe (#157310, #157306,
Colin Walters):
* gdk-pixbuf-io.h (enum GdkPixbufFormatFlags): Add
GDK_PIXBUF_FORMAT_THREADSAFE to indicate that an image loader
is threadsafe.
* gdk-pixbuf-io.c (get_file_formats, _gdk_pixbuf_load_module):
Use a lock to make initialization of global data structures
threadsafe.
* gdk-pixbuf-private.h:
* gdk-pixbuf-io.c (_gdk_pixbuf_lock, _gdk_pixbuf_unlock):
Auxiliary functions which use another lock to protect
threadunsafe image loaders.
* gdk-pixbuf-io.c (gdk_pixbuf_real_save):
(save_to_callback_with_tmp_file):
(gdk_pixbuf_real_save_to_callback):
(gdk_pixbuf_new_from_xpm_data):
(_gdk_pixbuf_generic_image_load):
* gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
* gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module):
(gdk_pixbuf_loader_close):
(gdk_pixbuf_loader_finalize):
Use _gdk_pixbuf_lock() and _gdk_pixbuf_unlock().
* io-ani.c, io-bmp.c, io-gif.c, io-ico.c:
* io-jpeg.c, io-pcx.c, io-png.c, io-pnm.c:
* io-ras.c, io-tga.c, io-wbmp.c, io-xbm.c:
* io-xpm.c: Mark as threadsafe.
* io-tiff.c: Remove pointless locking, mark as
threadunsafe.

* io-gif.c, io-pnm.c, io-tga.c, io-xpm.c: Don't use
contractions like "don't" or "isn't" in error messages.
It isn't nice to use them in log entries either...

* gdk-pixbuf-loader.c (gdk_pixbuf_loader_size_func):
* gdk-pixbuf-loader.c (gdk_pixbuf_loader_set_size):
* gdk-pixbuf-loader.c (gdk_pixbuf_loader_init): Make it possible
to call gdk_pixbuf_loader_set_size (loader, 0, 0) by changing
the initial values of priv->width/height to -1.
* io-tiff.c (tiff_image_parse):
* io-ras.c (RAS2State):
* io-pnm.c (gdk_pixbuf__pnm_image_load_increment):
* io-pcx.c (gdk_pixbuf__pcx_load_increment):
* io-jpeg.c (gdk_pixbuf__jpeg_image_load_increment):
* io-png.c (png_info_callback):
* io-ico.c (DecodeHeader):
* io-bmp.c (DecodeHeader): Call size_func once the size is known,
even if the module can't make use of the scaling information. If
size_func returns 0, don't allocate a pixbuf and return, if
necessary with an error.
* gdk-pixbuf.h:
* gdk-pixbuf-io.c (gdk_pixbuf_get_file_info): A new function
to determine the type and size of an image file without loading
it completely. (#53725)
2003-02-18 Matthias Clasen <maclas@gmx.de>
* io-tga.c (pixbuf_flip_row):
(pixbuf_flip_vertically): Auxiliary functions used to implement
support for arbitrary origins.
(parse_data_for_row_pseudocolor):
(parse_data_for_row_truecolor):
(parse_data_for_row_grayscale):
(parse_data_for_row):
(fill_in_context): Remove the check for upper-left origin.
(parse_rle_data): Support arbitrary origins. (#105912)
* io-tga.c (fread_check):
(fseek_check):
(get_header_from_file):
(get_colormap_from_file):
(get_image_pseudocolor):
(swap_channels_pixbuf):
(get_image_truecolor):
(get_image_grayscale):
(gdk_pixbuf__tga_load): Remove the non-incremental load
implementation, since we have generic_image_load () now.
(gdk_pixbuf__tga_stop_load): Fix a potential crash discovered by
pixbuf-lowmem.
2003-02-14 Matthias Clasen <maclas@gmx.de>
* io-tga.c (try_preload):
(gdk_pixbuf__tga_load): Actually reject images with origin
not in the upper-left corner. (#105912)
* io-tga.c (get_contiguous_pixbuf): Helper function to create
a pixbuf with a contiguous pixel array while being careful about
overflow.
* io-tga.c (fill_in_context, get_image_pseudocolor,
get_image_truecolor, get_image_grayscale): Use
get_contiguous_pixbuf instead of manually allocating image
storage.
* io-xpm.c (pixbuf_create_from_xpm):
* io-pnm.c (gdk_pixbuf__pnm_image_load):
* io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
instead of manually allocating image storage.
* io-tga.c (try_colormap, gdk_pixbuf__tga_stop_load): Avoid a
double free error if reading the colormap fails.
* io-tiff.c (tiff_image_parse): Make TIFFReadRGBAImage stop on
errors, since it may otherwise segfault on certain bad TIFFs.
* io-tga.c: Fix assumptions on rowstride by manually allocating a
contiguous pixel buffer. Catch buffer overruns in RLE-modi.
Support grayscale + alpha (which can be written, but not read (!)
by the Gimp).
* test-images.h (tiff1_test_3), test-loaders.c (main): Add a
(#ifdef 0'ed) test provoking a segfault in TIFFReadDirectory().
* io-ico.c (DecodeHeader): Check that pixbuf could be allocated.
* test-images.h (ico_test_2), test-loaders.c (main): Test the
previous change.
* io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment): Don't write
beyond the end of buffer if width % 8 != 0.
* io-tga.c (try_preload): Enforce that ctx->hdr->type is one of
the supported types, otherwise parse_data_for_row () will not make
any progress, leading to an infinite loop.

* gdk-pixbuf-animation.c, gdk-pixbuf-loader.c, gdk-pixpuf.c,
io-gif-animation.c, io-gif.c, io-tiff.c, test-loaders.c: Remove
assorted G_OBJECT casts where unnecessary.
* gdk-pixbuf-loader.c: Call g_object_ref and g_object_unref
instead of gdk_pixbuf_animation_ref and gdk_pixbuf_animation_unref
resp.
* gdk-pixbuf-csource.c, io-bmp.c, io-gif-animation.c, io-ico.c,
io-jpeg.c, io-png.c, io-pnm.c, io-ras.c, io-tga.c, io-wbmp.c,
io-xbm.c, io-xpm.c, test-gdk-pixbuf.c: Dito for gdk_pixbuf_ref and
gdk_pixbuf_unref.
* Makefile.am, pixops/Makefile.am: Compile everything with
-DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED
* gdk-pixdata.c: Use g_ascii_strup() instead of g_strup().
* io-xpm.c: Use g_ascii_strcasecmp() instead of g_strcasecmp().
* demos/testpixbuf-drawable.c, demos/testpixbuf-save.c,
demos/testpixbuf-scale.c, demos/testpixbuf.c: Call g_object_ref
and g_object_unref instead of gdk_pixbuf_ref and gdk_pixbuf_unref
resp.
