... non-latin unicode path.
g_win32_locale_filename_from_utf8() was sometimes returning NULL for
some paths on Windows. Then the call to gexiv2_metadata_open_path() with
a NULL value was crashing plug-ins.
This commit only prevents from crashing by simply failing to load
metadata when this occurs, which means losing metadata support on
Windows depending on filenames. A proper solution will have to be
implemented.
It seems old blend tool (from GIMP 2.8) was using manhattan distance,
whereas the new one uses euclidean. I guess there must be use cases for
both. In any case, it is a good idea to simply propose the option since
the property exists in the "gegl:distance-transform" operation.

Reap the child *after* we're done reading its output, so that we
can disable ptracing after reading, but before reaping. This
avoids a window during which the child is gone, but ptracing using
its PID is still allowed.
Clear the ptrace permission given to the child after it terminates,
so that a future process that happens to have the same PID the
child had can't ptrace us.
On Linux, when /proc/sys/kernel/yama/ptrace_scope is 1, a process
may only ptrace its descendants by default, which prevents the GDB
process spawned by gimp_stack_trace_print() from attaching to, and
producing a backtrace for, the calling process.
Use prctl() with PR_SET_PTRACER, when available, in the parent
process, to allow the child process to ptrace it.
It seems that older GDB (under version 7) are not handling very well
some common debug information format, in particular DWARF > 3. Such
version of GDB is usually not a problem since it is quite old (more than
10 years old, it would seem) so you don't see it anymore on any modern
GNU/Linux distribution. On FreeBSD on the other hand, it is still
available (probably for license reasons) and even installed by default!
As a consequence, it makes debugging fail, even though LLDB is also
installed by default.
That is even more of a problem because it would seem that GIMP is killed
(most likely by FreeBSD kernel according to the reporter tests) as a
side-effect of GDB failing, which is seriously bad, in particular since
we also use the debug dialog for non-fatal errors (which could therefore
end up killing GIMP as side effect of a bad GDB!).
So I add some GDB version check. I implement this without any dynamic
memory management, as usual, since this needs to happen also during
crash handling where the state is unstable and prone to memory
allocation failure.
I also add gimp_utils_backtrace_available() public API which can be used
by the Preferences.
The only debugger command which uses this value currently is gdb. And
even there, it doesn't look mandatory. The alternative call using "-p"
option does not require the program name. The manual doesn't say if
calling with the program name has any advantage (but I don't see why it
would, the PID is enough to find a process). Just in case, I leave the
prog_name parameter (because it's easier to make a parameter useless
than changing a libgimp* API) but simply allows setting it to NULL.
... backtrace_symbols() when possible.
When we allocate a new string, anyway we have memory allocation. But
when we just print to a file descriptor, this version of the API is
guaranteed without any memory allocation and therefore should always
work. This is important since allocations may fail in particular after
memory errors.
The value descriptions of GimpGradientColor,
GimpGradientSegmentColor, and GimpGradientSegmentType enums appear
in the on-canvas gradient editor UI, as combo-box items in the tool
GUI overlay. Since we want to keep the overlay as small as
possible, we previously used abbreviations for these descriptions
(e.g., "FG (t)", instead of "Foreground (transparent)").
Replace the abbreviated descriptions with unabbreviated ones, and
move the abbreviations to the "abbrev" parameter. This way we get
the abbreviated version in the combo-box, and the full version in
the combo-box's menu.
Update the dprod production of generated enum files to include
abbreviated value descriptions, as per the previous commits.
Add a comment for translators above the abbreviated descriptions,
specifying the full description they abbreviate.
Add support for specifying an abbreviated description for enum/
flags values, which can be used in contexts where the full
description is too long.
Since the exact layout and size of Gimp{Enum,Flags}Desc is part of
the ABI, we can't simply add a field to these structs to hold the
abbreviated description. Instead, we use the fact that entries
with a repeated value in the value descriptions array are ignored,
and that the array is NULL terminated (in particular, that all non-
NULL entries are followed by at least one additional entry), and
specify the abbreviation in the "value_desc" field of the entry
that immediately follows the initial entry for a given value,
setting the "value" field of both entries to the same value.
Right now this behavior is undocumented, so there is no proper way
to specify abbreviated descriptions in the API, and is only meant
to be used in generated enum files.
to gimp_base_compat_enums_init() and move its prototype from
gimputils.h to gimpbase-private.h; it's not supposed to be
public API even though it's callable from the outside.
Allows setting the midpoint's position, blending function, and
coloring type.
The midpoint can be converted to a stop, and centered, through
editor buttons.
...protocol calls.
Some calls are waiting for answers, for instance plugin procedures, and
tiles which expects data and acknoledgement.
This would result in error messages such as:
"expected tile ack and received: 5" (5 is GP_PROC_RUN)
Typically because a thread would run a procedure while another would
receive tiles.
...on macOS (with macports)
Changed gimp_metadata_get_guid() to use a GRand that automatically
seeds itself from /dev/urandom (if available) or the current time.
...resources to be loaded and shown multiple times
Change gimp_path_parse() to filter out duplicate paths. This is the
function at the bottom which is used by everything else, so should
generically catch all duplicates.
Commit 1e6acbd4e1 modified the
generated enum recipes to run gimp-mkenums from the source
directory, instead of the build directory, so that only the
basenames of the corresponding header files would appear in
the comment at the top of the generated files. This was a
mistake -- $(GIMP_MKENUMS) is expecting to be invoked from the
build directory.
Switch back to running gimp-mkenums from the build directory. To
avoid including the relative path from the build directory to the
source directory in the generated file, add a @basename@ production
variable to gimp-mkenums, which exapnds to the basename of the
input file, and use it instead of @filename@ in the recipes for the
generated enum files.
When regenerating an enum file, don't copy it back to the source
directory if it hasn't actually changed. This allows using a read-
only source directory where the enum header is newer than the
generated file, as long as they're not really out of sync.
OTOH, *do* touch the generated source-dir file even when unchanged,
in order to avoid re-running its recipe on the next build, however,
allow this to silently fail (which is harmless).
Add the additional enum values to enum GimpSelectCriterion, and
the few needed lines to gimppickable-contiguous-region.c.
It's horribly slow, but works.
We check them into git, so this makes it easier to keep them in
sync when using a separate build directory.
Case in point -- this commit also syncs a few enum files that went
out-of-sync with their headers.
It was agreed that we should write "plug-in" consistently. Only possibly
user-visible strings were updated.
Thanks to scootergrisen for a first patch which could not make it
after changing decision on the canonical writing.
which unlike HSL Lightness is actually physically meaningful and
also generally speaking much more useful than HSL Lightness.
Change "Lightness" to "Lightness (HSL)" to make it clear that
the "Lightness" in the Colors/Desaturate/Desaturate menu is not the
same as "Lightness" in LAB/LCH.
For completeness add the option to desaturate to "Value (HSV)".
Add links in app/operations/gimpoperationdesaturate.c
to the Wikipedia article with definitions of L/I/V in HSL/HSI/HSV.
being exported to libgimp, and having a non-exported value, this is a
horrible mess like with GimpLayerMode, but at least the cruft value
names are deprecated now.
C++ won't allow us to use GimpLayerMode in the API where we used to
have GimpLayerModeEffects.
Move GimpLayerModeEffects to libgimpbase/gimpcompatenums.h so it's
not in the API any longer, and instead typedef and define stuff in
libgimp/gimptypes.h, and adapt the compat enum registering code
accordingly.
Which are entirely private (not installed). They contain compat values
for enums where values have been renamed in gimpbaseenums.h. The old
names get the old nicks generated so the new values in gimpbaseenums.h
can have proper new nicks. Register them as compat enums using
mechanism introduced for the GimpLayerMode change.
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
Add property "color-tag" of type enum GimpColorTag to GimpItem so all
layers, channels and paths can be tagged with a color.
For interoperability, use the color list from Krita which is a
superset of Photoshop's colors.
Features a "Color Tag" submenu in the layers, channels and paths
menus, a row of color radio buttons in the properties dialogs,
undo and PDB API.
As a side effect, some common code is now factores out into
items-actions.[ch] and items-commands.[ch] which adds visible, linked
and lock actions for layers and channels.
Don't skip the first 10 bytes. That code was there to skip the magic
"GIMP_XMP_1" of the old "gimp-metadata" parasite. Instead, properly
check for that magic in xcf_load_image() and pass only the actual XMP
to gimp_metadata_set_from_xmp(). Also remove the +10 hack in file-exr.
"exif-data" parasite
To migrate old "exif-data" parasites to GimpMetadata
an exif-only jpeg file is generated in memory, but its
APP1 marker length was 2 bytes short resulting in a
CRITICAL warning:
** (gimp-2.9:9): CRITICAL **: Directory Photo: IFD exceeds data buffer, cannot read next pointer.
Properly terminating the jpeg with an EOI marker also
gets rid of the WARNING:
** (gimp-2.9:9): WARNING **: JPEG format error, rc = 5
Since we have many themes now, this new name better indicates that it
is meant to follow your desktop theme settings.
Also it will likely not remain the default theme.
Add GIMP_DESATURATE_LUMINANCE to enum GimpDesaturateMode and rename
GIMP_DESATURATE_LUMINOSITY to GIMP_DESATURATE_LUMA.
Keep GIMP_DESATURATE_LUMINOSITY as deprecated compat value and add it
to the script-fo and pygimp compat constants.
Change GimpOperationDesaturate to process GIMP_DESATURATE_LUMINANCE
with linear "RGBA float".
Change the logic in gimp_metadata_get_colorspace() to be like in the
respective KExiv2 function, which looks pretty well done. No guarantee
of correctness, this just looks more logical than before :)
Some refactoring: add gimp_metadata_get,set_colorspace() and a new
enum GimpMetadataColorspace which so far can be one of { UNSPECIFIED,
UNCALIBRATED, SRGB, ADOBERGB }. The setter is untested and I don't
know if it's doing the right thing, please review. Use the getter in
gimp_image_metadata_load_finish(), so complex metadata logic and
profile creation/setting are separated.
Add flag GIMP_METADATA_LOAD_COLORSPACE which defaults to TRUE, and in
gimp_image_metadata_load_finish(), assign AdobeRGB to the image if
Exif.Iop.InteroperabilityIndex says "R03". This is most likely very
incomplete because there are quite some other colorspace tags in
various parts of the image metadata.
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.
gimp_param_unit_value_validate() set a value to itself to not
change the value, which was strange though not particularly wrong.
Found by Coverity Scan.
Add gimp_file_show_in_file_manager() to libgimpbase and a menu item
in app which shows the image's file (if any) in the file manager.
Implemented calling the org.freedesktop.FileManager1 interface
and dropped snippets found on stackoverflow for somebody to
turn into working code for OSX and Windows.
