* pathops coincidence and security rewriteGravatar caryclark2016-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most changes stem from working on an examples bracketed by #if DEBUG_UNDER_DEVELOPMENT // tiger These exposed many problems with coincident curves, as well as errors throughout the code. Fixing these errors also fixed a number of fuzzer-inspired bug reports. * Line/Curve Intersections Check to see if the end of the line nearly intersects the curve. This was a FIXME in the old code. * Performance Use a central chunk allocator. Plumb the allocator into the global variable state so that it can be shared. (Note that 'SkGlobalState' is allocated on the stack and is visible to children functions but not other threads.) * Refactor Let SkOpAngle grow up from a structure to a class. Let SkCoincidentSpans grow up from a structure to a class. Rename enum Alias to AliasMatch. * Coincidence Rewrite Add more debugging to coincidence detection. Parallel debugging routines have read-only logic to report the current coincidence state so that steps through the logic can expose whether things got better or worse. More functions can error-out and cause the pathops engine to non-destructively exit. * Accuracy Remove code that adjusted point locations. Instead, offset the curve part so that sorted curves all use the same origin. Reduce the size (and influence) of magic numbers. * Testing The debug suite with verify and the full release suite ./out/Debug/pathops_unittest -v -V ./out/Release/pathops_unittest -v -V -x expose one error. That error is captured as cubics_d3. This error exists in the checked in code as well.

* fix pathops fuzz bugsGravatar caryclark2016-06-08
| | | | | | | | | | | | | | | | | | | Fail out in a couple of new places when the input data is very large and exceeds the limits of the pathops machinery. Most of the change here plumbs in a way to exclude an assert in one of these exceptional cases. The current SkAddIntersection implementation and the inner functions it calls has no way to report an error to the root caller for an early exit, so rather than add that in, exclude the assert when the test that would trigger it runs (allowing the test to otherwise ensure that it properly fails).

* fix security bugGravatar caryclark2016-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix is a tradeoff. It changes intersection to treat a case where one coincident run is intersected at one point and the other edge is not as continuing to be a span. The old code tried to treat this as a single point. The old code is probably right, but this change alone made the data structures inconsistent. Later, extending the coincident runs would fail by incorrectly discarding the single point intersection. As a result, this fixes the security test and one other, but makes a different test fail. Isolating the failure uncovered a reduced case that fails with and without the change, so there are more serious problems here. Those problems are addressed in a separate CL. Many of the test edits below remove ill-thought out debugging messaging that fire off global state, which isn't usable in a multi-threaded test environment. In the end, with this fix, all existing tests (modulo one new failure and one new non-failure) pass in debug and in the extended release test suites.

* Enabling clip stack flattening exercises path ops.Gravatar caryclark2015-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Iterating through the 903K skps that represent the imagable 1M top web pages triggers a number of bugs, some of which are addressed here. Some web pages trigger intersecting cubic representations of arc with their conic counterparts. This exposed a flaw in coincident detection that caused an infinite loop. The loop alternatively extended the coincident section and, determining the that the bounds of the curve pairs did not overlap, deleted the extension. Track the number of times the coincident detection is called, and if it exceeds an empirically found limit, assume that the curves are coincident and force it to be so. The loop count limit can be determined by enabling DEBUG_T_SECT_LOOP_COUNT and running all tests. The largest count is reported on completion. Another class of bugs was caused by concident detection duplicating nearly identical points that had been merged earlier. To track these bugs, the 'handle coincidence' code was duplicated as a const debug variety that reported if one of a dozen or so irregularities are present; then it is easier to see when a block of code that fixes one irregularity regresses another. Creating the debug const code version exposed some non-debug code that could be const, and some that was experimental and could be removed. Set DEBUG_COINCIDENCE to track coincidence health and handling. For running on Chrome, DEBUG_VERIFY checks the result of pathops against the same operation using SkRegion to verify that the results are nearly the same. When visualizing the pathops work using tools/pathops_visualizer.htm, set DEBUG_DUMP_ALIGNMENT to see the curves after they've been aligned for coincidence. Other bugs fixed include detecting when a section of a pair of curves have devolved into lines and are coincident. TBR=reed@google.com Review URL: https://codereview.chromium.org/1394503003

| | | | | | | | | | | | | | | | | | | | | | | | This should be a drop-in replacement for most for-loops to make them run in parallel: for (int i = 0; i < N; i++) { code... } ~~~> sk_parallel_for(N, [&](int i) { code... }); This is just syntax sugar over SkTaskGroup to make this use case really easy to write. There's no more overhead that we weren't already forced to add using an interface like batch(), and no extra heap allocations. I've replaced 3 uses of SkTaskGroup with sk_parallel_for: 1) My unit tests for SkOnce. 2) Cary's path fuzzer. 3) SkMultiPictureDraw. Performance should be the same.

This replacement shoots axis-aligned rays through all intersecting edges to find the outermost one either horizontally or vertically. The resulting code is smaller and twice as fast. To support this, most of the horizontal / vertical intersection code was rewritten and standardized, and old code supporting the top-directed winding was deleted. Contours were pointed to by an SkTDArray. Instead, put them in a linked list, and designate the list head with its own class to ensure that methods that take lists of contours start at the top. This change removed a large percentage of memory allocations used by path ops. TBR=reed@google.com BUG=skia:3588 Review URL: https://codereview.chromium.org/1111333002

| | | | | | | | | | | | | | | | | | | | | 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.
