Add a "markers" page to the performance-log viewer, which lists
the event markers contained in the log, and allows navigating
between them.
Update docs accordingly.
In the perofmance-log viewer, add header-bar buttons to clear and
invert the selection, and allow inverting the selection by ctrl-
right-clicking on the sample-selection area.
Update the docs.
In sample-search predicates, remove the "exclusive" parameter of
the "function()" function, and replace it with optional "id" and
"state" parameters, which limit the match to the call-stacks of
matching threads, as per the "thread()" function.
Sort the backtrace thread-list by thread ID.
In the performance-log viewer's profile view, allow sorting the
call-graph tree-views by function name, in addition to the
inclusive/exclusive frequencies.
In the performance-log viewer's profile view, displasy in-line bar-
chart-like visualization of function and source-line sample
percentages, as part of the corresponding tree-view cells.
In performance-log-viewer.py, fix thread-state toggling in the
profile-view thread-filter popover, when not all threads are
included in the current selection.
Add a new performance-log-coalesce.py tool, which groups together
performance-log address-map entries belonging to the same function
into a single symbol, by filling-in missing base symbol addresses.
The addresses are grouped such that each set of addresses
corresponding to a symbol of the same name, in the same source
file, are given the same (unique, but arbitrary) base address.
See the previous commit for why this is necessary.
This should work fine in most cases, however, for logs produced on
Windows, it can over-coalesce addresses belonging to different C++
lambda-functions in the same source file, since they all seem to be
given the same _FUN symbol name.
Use the new tool as part of the pipeline in performance-log-viewer.
Add an annotated source view to the performance-log viewer's
profile view. When selecting the [Self] entry of a function's
profile, for which source information is available and whose source
is found locally, a new column opens, showing the function's
source, annotated with sample statistics. Header-bar buttons allow
navigation through the annotated lines, selection of all the
samples corresponding to a given line, and opening the text editor
at the current line.
... when selecting a function's samples
Since we now preserve the call-graph path across state changes,
there's no need to explictly set the path after selecting a
function's samples in the profile view.
... in backtraces
In the performance-log viewer's backtrace viewer, show a document
icon next to stack frames with source-location information, whose
source file is found locally. Clicking the icon opens the source
file in a text editor at the relevant line.
Two environment variables control this feature:
- PERFORMANCE_LOG_VIEWER_PATH is a list of colon-separated
directories in which to look for source files. If this
variable is undefined, the current directory is used.
- PERFORMANCE_LOG_VIEWER_EDITOR is the command to use to launch
the text editor, for editing a specific file at a specific
line. The special strings "{file}" and "{line}" are replaced
with the filename and line-number, respectively. If this
variable is undefined, "xdg-open {file}" is used.
Don't take infinite values into account when calculating the
vertical scale of sample graphs, and rather display infinite values
as dashed lines at the top of the graph.
Fix int-ratio variable formatting when the input is NaN, which can
happen when calculating the standard deviation, if all the values
are infinite.
Fix keyboard sample-range selection.
Deselect all samples when right-clicking a sample graph.
In the performance-log viewer, add an option to filter which
threads, and which states of each thread, are included in the
profile. By default, all threads in the RUNNING state are
included.
In the performance-log viewer, defer updates to the various UI
elements when the selection changes until they're actually shown.
This improves responsiveness when changing the selection.
Use the less-ambiguous, if just as clumsy,
"format-indent-more/less" icons, to stand for the
caller -> callee, and callee -> caller, directions, respectively.
Fix searching for samples by thread name, in particular, when there
are unnamed threads.
Use GtkMenuButton, instead of GtkButton, for the find-samples
header button.
Add mnemonics to the find-samples popover.
performance-log-viewer.py is a viewer for GIMP performance logs.
The viewer is made up of two parts: a sample-selection area at the
top, and an information area at the bottom.
The sample-selection area visualizes the sampled variables and
markers using a simultaneous set of plots, and displays the
currently selected samples. Samples can be selected directly
through the sample-selection area, or by other means, such as
searching for all samples satisfying a certain condition, or
containing a certain function.
The information area shows global information stored in the log, as
well as information specific to the currently selected samples,
including variable listing and statistics, full backtrace, and
profile/call-graph information.
Note that performance-log-viewer.py takes its input from STDIN,
like the rest of the performance-log tools, and is therefore
suitable for use as part of a pipeline. For standalone use, the
performance-log-viewer driver is also included, which takes the log
file as a command-line argument, and processes it through an
appropriate pipeline before feeding it to the viewer.
The "running" attribute (readable through
gimp_backtrace_is_thread_running(), and recorded in the performance
log) specifies if the thread was in a running or suspended state at
the time the backtrace was taken. It is accurate on Linux, but
only approximated on Windows.
Adapt the performance-log-expand.py tool to maintain this attribute
(and any future thread attributes we might add).
performance-log-expand.py decodes a delta-encoded performance log
by expanding the deltas, producing a log where each sample (and
other relevant elements) contain complete information. Note that
the structure of expanded logs is identical to that of delta-
encoded logs, the expanded log simply has no deltas.
performance-log-resolve.py resolves symbol information in
backtraces. The logs produced by GIMP only specify the program
counter at each stack frame, providing an address-map to map
program-counter addresses to actual symbols separately. This tool
looks up each program-counter address in the address map,
incorporating the relevant symbol information directly into the
backtrace.
Both tools read their input from STDIN, and write their output to
STDOUT, and can be chained in a pipeline (with
gimp-performance-log-expand.py appearing first).
Note that these tools require Python 3.
This tool has been outdated for some time now as we don't generate an
"inverted icons" theme anymore. This is all done through CSS from a
single symbolic icon theme.
Though no error was raised during a native build, a cross-build was
choking on this missing link to libgimpbase and failing.
The error returned by the linker though was a bit amiss.
Fixes:
> gimp-test-clipboard.o: In function `test_clipboard_copy_callback':
> tools/gimp-test-clipboard.c:419: undefined reference to `g_file_get_contents'
> collect2: error: ld returned 1 exit status
(cherry picked from commit 0865e9db1f)
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.
