* Make SkGLContext lifetime more well-definedGravatar kkinnunen2016-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove refcounting from SkGLContext. SkGLContext is expected to behave like GrContextFactory would own it, as implied by the GrContextFactory function. If it is refcounted, this does not hold. Also other use sites, such as in SkOSWindow_win (command buffer gl object), confirm the behavior. The object is explicitly owned and destroyed, not shared. Also fixes potential crashes from using GL context of an abandoned context. Also fixes potential crashes in DM/nanobench, if the GrContext lives longer than GLContext through internal refing of GrContext. Moves the non-trivial implementations from GrContextFactory.h to .cpp, just for consistency sake. Changes pathops_unittest.gyp. The pathops_unittest uses GrContextFactory, but did not link to its implementation. The reason they worked was that the implementation used (constructors, destructors) happened to be in the .h file. This works towards being able to use command buffer and NVPR from the SampleApp. BUG=skia:2992 GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1511773005 Committed: https://skia.googlesource.com/skia/+/830e012187f951d49d7e46e196ac8d1e653a25da Review URL: https://codereview.chromium.org/1511773005

* cumulative pathops patchGravatar caryclark2015-03-26
| | | | | | | | | | | | | | | | | | | | | Replace the implicit curve intersection with a geometric curve intersection. The implicit intersection proved mathematically unstable and took a long time to zero in on an answer. Use pointers instead of indices to refer to parts of curves. Indices required awkward renumbering. Unify t and point values so that small intervals can be eliminated in one pass. Break cubics up front to eliminate loops and cusps. Make the Simplify and Op code more regular and eliminate arbitrary differences. Add a builder that takes an array of paths and operators. Delete unused code.

* SkThreadPool ~~> SkTaskGroupGravatar mtklein2014-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SkTaskGroup is like SkThreadPool except the threads stay in one global pool. Each SkTaskGroup itself is tiny (4 bytes) and its wait() method applies only to tasks add()ed to that instance, not the whole thread pool. This means we don't need to bring up new thread pools when tests themselves want to use multithreading (e.g. pathops, quilt). We just create a new SkTaskGroup and wait for that to complete. This should be more efficient, and allow us to expand where we use threads to really latency sensitive places. E.g. we can probably now use these in nanobench for CPU .skp rendering. Now that all threads are sharing the same pool, I think we can remove most of the custom mechanism pathops tests use to control threading. They'll just ride on the global pool with all other tests now. This (temporarily?) removes the GPU multithreading feature from DM, which we don't use. On my desktop, DM runs a little faster (57s -> 55s) in Debug, and a lot faster in Release (36s -> 24s). The bots show speedups of similar proportions, cutting more than a minute off the N4/Release and Win7/Debug runtimes.

* share dm and command flagsGravatar caryclark2014-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Share command flags between dm and unit tests. Also, allow dm's core to be included by itself and iOSShell. Command line flags that are the same (or nearly the same) in DM and in skia_tests have been moved to common_flags. Authors, please check to see that the shared common flag is correct for the tool. For iOS, the 'tool_main' entry point has a wrapper to allow multiple tools to be statically linked in the iOSShell. Since SkCommandLineFlags::Parse can only be called once, these calls are disabled in the IOS build. Since the iOS app directory is dynamically assigned a name, use '@' to select it. (This is the same convention chosen by the Mobile Harness iOS file system utilities.) Move the heart of dm.gyp into dm.gypi so that it can be included by itself and iOSShell.gyp. Add tools/flags/SkCommonFlags.* to define and declare common command line flags. Add support for dm to iOSShell.

| | | | | | | | | | | | | | | | | | | | | | | | Mike K: please sanity check Test.cpp and skia_test.cpp Feel free to look at the rest, but I don't expect any in depth review of path ops innards. Path Ops first iteration used QuickSort to order segments radiating from an intersection to compute the winding rule. This revision uses a circular sort instead. Breaking out the circular sort into its own long-lived structure (SkOpAngle) allows doing less work and provides a home for caching additional sorting data. The circle sort is more stable than the former sort, has a robust ordering and fewer exceptions. It finds unsortable ordering less often. It is less reliant on the initial curve tangent, using convex hulls instead whenever it can. Additional debug validation makes sure that the computed structures are self-consistent. A new visualization tool helps verify that the angle ordering is correct. The 70+M tests pass with this change on Windows, Mac, Linux 32 and Linux 64 in debug and release.

* Add implementation of path opsGravatar caryclark@google.com2013-04-08
This CL depends on https://codereview.chromium.org/12880016/ "Add intersections for path ops" Given a path, iterate through its contour, and construct an array of segments containing its curves. Intersect each curve with every other curve, and for cubics, with itself. Given the set of intersections, find one with the smallest y and sort the curves eminating from the intersection. Assign each curve a winding value. Operate on the curves, keeping and discarding them according to the current operation and the sum of the winding values. Assemble the kept curves into an output path. Review URL: https://codereview.chromium.org/13094010 git-svn-id: http://skia.googlecode.com/svn/trunk@8553 2bbb7eff-a529-9590-31e7-b0007b416f81
