2016-09-29Remove FX_BOOL from font_int.hnpm
It is not necessary. For some methods, bool can be used instead. For some other methods, the returned boolean is never used, so they can be void. Review-Url: https://codereview.chromium.org/2382803002

2016-09-22Rename CPDF_CountedObject to CFX_WeakPtr::Handlechromium/2869tsepez
This better describes its purpose, and reduces confusion with the CFX_CountRef class, which is unrelated. The WeakPtr class itself that manipulates handles is NYI. Review-Url: https://codereview.chromium.org/2366673003

2016-09-21Remove some objnum locals with AddIndirectObjecttsepez
Also, it's idempotent, so simplify some logic in callers to not care if objnum is zero. The alternate forms are rarely used, using the objnum form makes it clear that SetReferenceFor() can't possibly register the object as a side-effect. Review-Url: https://codereview.chromium.org/2361713002

2016-09-20Fix memory leaking on ClosePage.art-snake
BUG=79367, 48791 The fonts was not cleared after unloading pages. Test pdf: http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf For this file, we have ~5 fonts per page, which equal ~1 Mb per page. In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory. Memory usage of PDF Plugin: before this CL: ~660 Mb after this CL: ~100 Mb This is last part of reverted CL: Original CL: https://codereview.chromium.org/2158023002 Revert reason: BUG=647612 Fix bug CL: https://codereview.chromium.org/2350193003 Previous CL: https://codereview.chromium.org/2350243002 Review-Url: https://codereview.chromium.org/2351193002
2016-09-20Assert that dictionary can own the objects it is given.tsepez
Upon indirect object holder destruction, all indirect objects are destroyed -- currently by order of increasing object number -- but ideally without ordering constraints. So currently, we can get away with a dictionary pointing directly at an indirect object with a higher number. It gets destroyed first, invoking Release() on its subordinates, which skips destroying them if they are indirect objects. But we don't want to rely on this artifact of destruction order. Should it happen to be reversed, the dictionary would invoke Release() on freed memory. Interestingly, CPDF_Array skirts the issue by replacing any indirect objects it is given with references. Not clear whether we should do the same thing for dictionaries, or remove it from arrays. The technique certainly complicates understanding ownership. The one violation found is in the unittest that broke the previous CL which tried to use unique_ptrs in indirect object holder. Review-Url: https://codereview.chromium.org/2353093002
2016-09-20Refactor CFX_FontCache to have only one in GE Module.art-snake

2016-09-19Clean up CPDF_Stream.tsepez
Replace the CPDF_Stream(nullptr, 0, nullptr) pattern with a default ctor. Remove unused parameters from CPDF_Stream::SetData(). Both are always passed as FALSE. CPDF_Stream declared its own m_GenNum, which shadowed the one in CPDF_Object. It was used only to distinguish file/memory streams, so add a bool explicitly for this purpose. Remove the union, it would be sad if we confused user data with a C++ object with virtual function calls. Use unique_ptrs with appropriate deleters to manage memory.
