The code was basically leaking memory everywhere, and apparently on
purpose (according to a top comment). Even on short-lived process, not
properly managing memory is not a good habit, especially if we plan to
maintain a program for the long run.
So here are some fixes. I'm sure I must have missed some places (code
was a mess), and hopefully I broke nothing. But that's good for now. At
least it is somewhat sane code now.
Since commit 58fa382001, gimptool would accept source files with
non-standard extensions when using known C or C++ compilers. This would
include source with no extensions at all.
When this happens, do not try to set a pointer to a non-existing dot
separator to '\0'. That obviously segfaults.
Last commit caused -xobjective-c to be passed during linking on
Mac, causing object files to be treated as source files. Add a
-xnone flag to AM_LDFLAGS, canceling the effect of -xobjective-c.
Additinally, add a -xobjective-c++ flag to AM_CXXFLAGS, so that we
can use Objective-C in C++ files on Mac, if we ever need to.
On Mac, pass -xobjective-c to the compiler through AM_CFLAGS, not
AM_CPPFLAGS, so that it's only used for C sources, and not C++
sources. In the latter case, it clashes with the -std=... flag,
spewing an error. Thanks, Partha :)
Move gimp-debug-tools.c from tools/ to a new app-tools/ subdir,
which should contain external tools needed by app/, and which is
built *after* app/ (unlinke tools/). This allows gimp-debug-tool
to depend on libapp and libappwidgets, instead of on actual source
files from app/. Building sources from app/ in another subdir
screws with the distclean rules, and breaks distcheck.
... stacktrace into a file on non-Win32 systems.
This has a few advantages:
- First, we don't need to duplicate stacktrace code inside the
independent gimp-debug-tool (I even noticed that the version in the
tool was gdb-only and not updated for lldb fallback; proof that code
duplication is evil!). Instead, even on a crash, we can create the
stacktrace from the main binary and simply pass it as a file.
- Secondly, that allows to fallback to the backtrace() API even for
crashes (this was not possible if the backtrace was done from a
completely different process). That's nice because this makes that we
will always get backtraces in Linux (even though backtrace() API is
not as nice as gdb/lldb, it's better than nothing).
- Finally this makes the code smaller (i.e. easier to maintain), more
consistent and similar on all platforms.
Since commit 9fdf35550b, I removed the GIMP_APP_GLUE_COMPILATION check
because we need to have the whole versioning info from the new debug
widget. It just makes sense to go further and just make this a proper
internal API to get version information.
AFAIK this means on all platforms but Win32 and macOS which would rather
need relative path and therefore cannot make use of build-time
LIBEXECDIR. Anyway on these platforms, leaving the binary in BINDIR is
not likely to "pollute" too much as it would on Linux or BSD where
people often use terminal.
* Type pid_t is not cross-platform. Just use int instead, and convert it
to respective type on each platform.
* Get rid of several useless include which should have been removed a
few commits ago, when I reimplemented the backtrace function.
* Better handle the various macros in gimp_eek() (between G_OS_WIN32,
HAVE_EXCHNDL and GIMP_CONSOLE_COMPILATION, but also no_interface and
generate_backtrace options, that was a bit messy).
* Make gimpdebug now always built, whatever the platform.
The feature already exists in our code and produces backtraces upon a
crash into a file. The only difference is that we are now getting the
file contents and showing it in our new debug dialog, so that it works
similarly on all platform (and therefore making the debug info visible
to people, otherwise they would never report, even though the data is
generated).
The difference with gdb/lldb is that it doesn't allow backtraces at
random points (for debugging non-fatal yet bad errors). Also the API has
just 2 functions and in particular an ExcHndlInit() but no way to unload
the feature. So we don't need the debugging page in Preferences because
the switch option would not work. On Windows, the feature will be
decided at build time only.
Last point: the code is untested on Windows so far. I assume it would
work, but there is at least one point I am unsure of: will ExcHndl have
already generated the backtrace file when gimpdebug runs? If not, I will
have to let gimp die first to be able to get the backtrace.
This is just a bit more consistent with existing code. Also build the
gimpdebug tool only when GIMP_CONSOLE_COMPILATION is not set and run
when --no-interface CLI option is not set since it is a GUI tool.
This was a bit harder since even though we handle fatal signals,
allowing us to do any last action before GIMP crashes, it seems more
memory allocation is not allowed at this time. So creating a dialog or
simply getting the return output of gdb into the main process is not
allowed. What I do instead is running a separate program (gimpdebug)
which will take care of creating the new dialog and running a debugger.
I still use GimpCriticalDialog code from this separate binary, while I
continue to use this widget also within GIMP for non-fatal errors. The
reason why we still want to use it within GIMP is that we can bundle
several non-fatal errors and backtrace this way (fatal errors don't
return anyway) and it's easier to do so when created from the main
process.
It never belonged inside "tools". Also rename its "pdb" subdirectory
to "groups". This had to happen before 2.10 so cherry-picking between
branches doesn't become a nightmare in the future.
Add an "@if (<cond>)@ <text> @endif@" conditional-inclusion
construct to all productions, which expands to <text> if <cond> (a
perl condition) is true, or to nothing otherwise.
Allow enum files to specify abbreviated value descriptions, using
an 'abbrev="foo"' comment, and add a @valueabbrev@ substitution for
vprod and dprod, which expands to the corresponding abbreviation
(or to NULL, if no abbreviation is specified for the value).
Make internal data objects non-renamable, even if they're writable,
through gimp_data_is_name_editable(). Currently, the only such
object is the custom gradient.
Prevent changing the name of non-renamable data by making the name
entry of GimpDataEditor non-editable whenever
gimp_viewable_is_name_editable() is FALSE, even if the data is
otherwise editable.
Prevent the vairous PDB -rename() functions from renaming non-
renamable data, by adding a GimpPDBDataAccess flags type,
specifying the desired access mode for the data -- any combination
of READ, WRITE, and RENAME -- and replacing the 'writable'
parameter of the gimp_pdb_get_foo() functions with an 'access'
parameter. Change the various .pdb files to use READ where they'd
used FALSE, and WRITE where they'd used TRUE; use RENAME, isntead
of WRITE, in the -rename() functions.
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.
Remove the invert-linear and invert-non-linear variants and simply add
"gboolean linear" to gimp-drawable-invert. This should actually be an
enum but I didn't find a good name right now...
and add gimp_drawable_invert_linear(). Also, finally deprecate
gimp_invert() and port all its uses in plug-ins and scripts to
gimp_drawable_invert_non_linear() so the result is the same.
...in both the core and libgimp.
Images now know what the default mode for new layers is:
- NORMAL for empty images
- NORMAL for images with any non-legacy layer
- NORMAL_LEGAVY for images with only legacy layers
This changes behavior when layers are created from the UI, but *also*
when created by plug-ins (yes there is a compat issue here):
- Most (all?) single-layer file importers now create NORMAL layers
- Screenshot, Webpage etc also create NORMAL layers
Scripts that create images from scratch (logos etc) should not be
affected because they usually have NORMAL_LEGACY hardcoded.
3rd party plug-ins and scripts will also behave old-style unless they
get ported to gimp_image_get_default_new_layer_mode().
this commit changes just those which make no difference to
functionality: property and object member defaults that get overridden
anyway, return values of g_return_val_if_fail(), some other stuff.
Add "gboolean with_filters" to gimp_drawable_calculate_histogram(),
which is passed as FALSE in almost all places, except the histogram
dockable where we want to see both the drawable's unmodified histogram
*and* the histogram after filters are applied.
Fedora hardens its packages by default since Fedora 23 and the home-made
CC call to build invert-svg needs position-independent code. The flag
-fPIC is apparently harmless in basic cases since it still builds when
non-hardened and the doc implies that it would just be ignored if not
supported by the target machine. As far as I could search, adding it
should not break other people's builds.
So what the heck. That's just a temporary build tool, let's add this
flag and see if others complain!
Similarly to what I did for CFLAGS and LDFLAGS in commit 20fdb8d, the
preprocessor flags for build tools should also be correctly defaulted
and used when building invert-svg.
... because LDFLAGS is ignored.
Firstly let's make sure that invert-svg build uses LDFLAGS_FOR_BUILD and
CFLAGS_FOR_BUILD; secondly, default these to LDFLAGS and CFLAGS
respectively when not-cross-compiling, unless values are explicitly set.
Allow NONE(0) for "wrapmode" (which translates to GEGL_ABYSS_NONE) in
the plug-in-edge PDB compat wrapper. The old plug-in accepted this
(undocumented) value and used a GimpPixelFetches in NONE mode.
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.
Add the additional enum values to enum GimpSelectCriterion, and
the few needed lines to gimppickable-contiguous-region.c.
It's horribly slow, but works.
Add "import-raw-plug-in" to gimprc, and a new procedure
gimp_register_file_handler_raw(). On startup, remove all load
procedures that are marked as "handles raw" but are not implemented by
the configured plug-in. Add the list of available plug-ins to prefs ->
import/export. Register all file-darktable procedures as handling raw.
and use them for the new image in "Paste as new image". We were using
the resolution and unit of the image the paste command was invoked
from, which is entirely random and useless.
Fix the edit-paste and edit-paste-as-new-image PDB wrappers to use
gimp_get_clipboard_object(), not just clipboard_buffer(), and deal
correctly with entire images in the clipboard.
Add a debug procedure group, living in 'debug.pdb', which would host
useful debug helper functions. Functions in this group are not part
of the stable API, and may be changed at any point.
All procedures added to 'debug.pdb' should have a 'debug_' prefix,
and use the new std_pdb_debug() macro, which adds the proper "here be
dragons" warning to their description.
Add two debug procedures: gimp-debug-timer-start() and
gimp-debug-timer-end(), which measure elapsed time, a la
GIMP_TIMER_{START,END}, and can be used to profile script-fu
commands.
We don't support subpixel source sampling, so there's no use in
pretending that we do. Demoting everything to int as soon as
possible helps guarantee that these values are at least rounded
properly and in fewer places.
Make sure we always round coordinates down, and not toward zero.
Keep using floats only in the signatures of the relevant PDB
functions.
Otherwise the file won't be included in the tarball (another consequence
is that `make distcheck` will fail) since this binary is not made the
common automake way on purpose.
Partially reverts commit 84439a8748.
The fact that tools/invert-svg was kind of manually compiled was on
purpose. Using the automake syntax with any of the *_PROGRAMS compiles
for the host OS, but this tool is only for compile-time.
This fixes cross-compilation.
As for compute_svg_viewbox, let's not build it for now because its
purpose was to help proper extraction of SVG icons from a single SVG
file. Unfortunately librsvg was not providing acceptable results anyway
so right now all SVG icons are manually exported. We keep the code for
future use when the library will improve.
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.
... since that's the color space it actually works in.
Keep the legacy "Color (HSV)" mode's name as is, wrong as it is,
since, well, that's what it used to be called...
Merge mode lays the source layer on top of the destination, same as
normal mode, however, it assumes the source and destination are two
parts of an original whole, and are therefore mutually exclusive.
This is useful for blending cut & pasted content without artifacts,
or for replacing erased content in general.
Calculates the dot product of the two input colors, and uses that
as the value for all the output color's components. Basically,
a per-pixel mono mixer.
Useful for custom desaturation, component extraction, and crazier
stuff (bump mapping!)
Include erase mode in the menu for layers and general paint tools.
This makes the eraser tool somewhat unnecessary, but allows for
interesting use cases (e.g., airbrush eraser, etc.)
... and get rid of the dedicated op. This gives us support for all
the blend/composite options for this mode.
Rename COLOR_ERASE to COLOR_ERASE_LEGACY, with perceptual blending/
compositing and immutable everything, and add a new COLOR_ERASE
mode, defaulting to linear blending/compositing, with mutable
everything. Modify affected code.
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.
A bitmask, specifying in which contexts a layer mode is applicable.
Can be a combination of:
- LAYER: usable as a layer mode for actual layers.
- GROUP: usable as a layer mode for layer groups. Currently, all
modes that specify LAYER also specify GROUP, and vice versa,
but the planned pass-through mode will be GROUP only.
- PAINT: can be used as a paint mode.
- FADE: can be used for fading.
Add a 'context' field to _GimpLayerModeInfo, and provide context
masks to all the modes.
Use the context mask for validation when setting a layer's mode.
The next commit will use the mask when populating the layer mode
menus.
and to operations/layer-modes/, respectively.
Add gimp_layer_modes_init() which asserts on the correct order of the
GimpLayerModeInfo array, and switch to accessing the array directly in
gimp_layer_mode_info().
Similar to the Photoshop mode of the same name. Assigns
either 0 or 1 to each of the channels, depending on whether the
sum of source and destination channel values is less than, or
greater than (or equals to), one, respectively.
This is equivalent to inverting the source, and using it to perform
per-pixel, per-channel threshold against the destination, which is
useful for various effects.
Largely based on a patch by Ell, with the enum type renamed and
various small changes. Adds another axis of configurability to the
existing layer mode madness, and is WIP too.
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.
For operations needing to override default behavior sub-classes should still be
used.
This commit also enables pinligh, vividlight and linearlight blend mode modes
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.
Change GimpHistogram to take a "gboolean linear" parameter and always
honor that parameter, so both kinds of histograms can now be created
for all drawables.
Add a horrible "Linear" toggle to the histogram dockable which always
defaults to the active layer's actual pixel format, but can be
switched at any time. This UI is ugly and needs to change.
On the PDB, default to gamma-corrected if the plug-in is unaware of
higher precision, and to the drawable's native pixel format otherwise.
Other places using histograms (e.g. levels, curves) are unchanged.
so the threshold can now be based on the GimpHistogramChannel enum.
Add a channel menu to the threshold dialog and a channel argument to
the PDB procedure (which is new in 2.10).
If I hadn't forgotten what the "RGB" channel is supposed to do I would
have implemented the RGB mode in GimpOperationThreshold correctly.
Right now I'm just guessing. Anyone?
They used to be 0..255, inherited from the old gimp_histogram() and
gimp_threshold() procedures. This commit deprecates these old
procedures and changes the ranges in the new gimp_drawable_histogram()
and gimp_drawable_threshold() to double with a 0.0..1.0 range.
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.
Add a GimpFillType argument to GimpItem::resize() and fill type
widgets to the canvas and layer resize dialogs. Fill the new parts of
the drawable according to fill type in gimp_drawable_resize(). Make
sure places that need the old behavior get GIMP_FILL_TRANSPARENT
passed by hardcoding it in the GimpItem::resize() implemetations of
channel, mask, selection etc.
and use gimp_file_new_for_config_path() and _get_config_path() when
dealing with them. We used a weird mix of config paths and plain
(filesystem encoded) paths, waiting to to break on umlauts or
whatever. The code in gimpcolorconfig.c was particularly bad.
Use the newly added clipboard for entire images to copy/paste layers
(we only create single-layer clipboard images, and use only the first
layer of any recieved image, the layers can be arbitrarily complex
though):
- change gimp_edit_copy,cut,paste() to return/take a GimpObject
that can be a GimpImage or GimpBuffer
- cut/copy the whole layer if there is no selection
- always paste layers as new layers, not floating selections
- always paste news layers on top of the active layer, where
we would attach a floating selection
- add enum GimpPasteType { FLOATING, FLOATING_INTO, NEW_LAYER }
- add GimpPasteType parameter to gimp_edit_paste() and handle all
three cases there because there is now a lot of common code
involved
- change all callers accordingly, use only legacy buffer pasting
from the PDB for now
librsvg has too many bugs and is not reliable for vectorial icon
extraction. I keep the code around for when it changes, but right now,
it is dead code.
isntead of the feather parameter, and pass it to
gimp_gegl_apply_border().
Make the necessary changes to the rest of the code to maintain the
current behavior.
Mass parameter alignment changes to gimpchannel.h. Sigh #2...
