CFX_FontCache refactoring: after this CL: Only one global CFX_FontCache used. Any cached items from it, are released, when its are not used. 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 Review-Url: https://codereview.chromium.org/2158023002
2016-09-13Sort include entries.dsinclair
This CL updates all of the includes to be correctly sorted. A PRESUBMIT warning is added (from chromium) that will warn if the includes are in the wrong order on upload. Review-Url: https://codereview.chromium.org/2337293002
2016-08-29Move CFX_SubstFont and CTTFontDesc into their own filesnpm
Review-Url: https://codereview.chromium.org/2292503002
2016-08-17Split fx_font into multiple files, part 1.npm
Moved classes CFX_FontCache and CFX_AutoFontCache into a separate file. Review-Url: https://codereview.chromium.org/2246223002
2016-08-11Remove fgas_system files.dsinclair
The two methods in fgas_system also exist in core/fxcrt/include/fx_ext with the FXSYS_ prefix instead of FX_. Remove the fgas_system files and use the fx_ext versions instead. Review-Url: https://codereview.chromium.org/2233133002
2016-08-11Guard against undefined shift.dsinclair
This Cl fixes the CFDE_XMLSyntaxParser::ParseTextChar() to handle entities where the value goes negative. Currently this could cause an undefined-shift as due to the (ch << 4) calls. Instead, detect if the value has gone negative and return a space character. BUG=chromium:603489 Review-Url: https://codereview.chromium.org/2223823003
2016-08-10Move CFX_RenderDevice, CFX_FxgeDevice, and CFX_GraphStateData into their own ↵npm
files. This is the third CL to separate fx_ge into classes, one per file. All fx_ge.h includes had to be replaced with new includes The method definitions for CFX_FxgeDevice were not moved to a single file. These methods are defined in two folders different from fxge/ge, so they were left untouched for now. Review-Url: https://codereview.chromium.org/2223213002
2016-08-08Move CFX_ClipRgn and CFX_PathData into their own files.npm
This is the second CL in an attempt to split up the classes in fxge/include/fx_ge.h into their own files. CFX_ClipRgn is moved to core/fxge/ge because it is only used in core/fxge. The header for CFX_PathData is left in core/fxge/include since it is used elsewhere. Review-Url: https://codereview.chromium.org/2216853004
2016-08-04Move CFX_GEModule into its own filenpm
This is the first CL in an attempt to split up the classes in fxge/include/fx_ge.h into their own files. Review-Url: https://codereview.chromium.org/2217663002
2016-08-04Use smart pointers for class owned pointers under xfa/fdeweili
Use smart pointer to replace raw pointer type for class owned member variables so that memory management will be easier. BUG=pdfium:518 Review-Url: https://codereview.chromium.org/2208423002
2016-07-25Use smart pointers for CFX_Font and CFX_Type3Font classesweili
For the class owned member variables, use std::unique_ptr or std::vector for memory management. BUG=pdfium:518 Review-Url: https://codereview.chromium.org/2169793002
2016-07-20Move CSSRuleCollection class to its own filenpm

2016-07-18Cleanup fgas/crt.dsinclair
This CL removes unused methods and default parameters from the fgas/crt code. Review-Url: https://codereview.chromium.org/2162503003
2016-07-11Cleanup ownership of parser membersdsinclair
Change m_pXMLDoc and m_pStream in CXFA_SimpleParser to be a unique_ptr. This allows removing the CloseParser() call from CXFA_DocumentParser as the items will get cleaned up automatically. Review-Url: https://codereview.chromium.org/2131653002
2016-06-23Remove NULL in xfa/dsinclair
This CL converts all NULL's to nullptr. All instances of comparison to nullptr have been removed. Review-Url: https://codereview.chromium.org/2095653002

2016-06-20Another round of fx_ge cleanup.thestig
- Clean up CFX_GEModule. - Remove duplicate #defines in fx_ge.h - Remove IsFontStyleFromCharCode() that always returns true. - Mark a FXTEXT_CHARPOS field as Mac only. Review-Url: https://codereview.chromium.org/2075333002
2016-06-18Make code compile with clang_use_chrome_plugin (final)weili
This change mainly contains files in xfa/ and fxjse/ directories which were not covered by previous changes. This is part of the efforts to make PDFium code compilable by Clang chromium style plugins. After this change, PDFium can be compiled with "clang_use_chrome_plugin=true" for GN build. Since clang_use_chrome_plugin is true by default, we no longer need to set this parameter explicitly. The changes are mainly the following: -- move inline constructor/destructor of complex class/struct out-of-line; -- add constructor/destructor of complex class/struct if not explicitly defined; -- add explicit out-of-line copy constructor when needed; -- move inline virtual functions out-of-line; -- Properly mark virtual functions with 'override'; -- some minor cleanups; BUG=pdfium:469 Review-Url: https://codereview.chromium.org/2072803002
2016-06-16Cleanup XML parser code.dsinclair
This Cl removes the CFDE_XMLSAXParser and CFDE_XMLDOMParser along with the ::LoadXML() method which would create them, it was never called. It also cleans up the use of virtual in the various XML classes. Review-Url: https://codereview.chromium.org/2067253002
2016-06-10Remove redundant casts, part 9.tsepez
Make CFDE_TxtEdtParag::m_lpData a int32_t*, not void*, since it is cast to int32_t everywhere it is used. Many fxbarcode casts are redundant, likely the result of previous generic PtrArray replacement with templated type. Review-Url: https://codereview.chromium.org/2059953002

2016-06-07Remove FDE_HVISUALOBJ.dsinclair
This CL removes the FDE_HVISUALOBJ in favour of the concrete FDE_TEXTEDITPIECE class. The parameter was removed from any method which didn't use it and the non-implemented methods were removed. Review-Url: https://codereview.chromium.org/2047693002
2016-06-06Remove unused CFDE_TxtEdtEngine::SetBufChunkSize().tsepez

2016-06-06Remove FDE_HDEVICESTATE.dsinclair

2016-06-06Make GetDevFont() return a CFX_Font* instead of void*tsepez
Then we can remove a bunch of casts. Review-Url: https://codereview.chromium.org/2033243004
2016-06-03Rename IFX_FontMgr to IFGAS_FontMgrtsepez
Avoid confusion with CFX_FontMgr, which does not inherit from IFX_FontMgr, and lives in a different layer of code. Do the same CFX_ -> CFGAS_ transformation for the concrete classes that implement IFGAS_FontMgr. Review-Url: https://codereview.chromium.org/2039463003
2016-06-03Rename IFX_Font to IFGAS_Fonttsepez
Avoid confusion with CFX_Font, which is defined in fxcrt, and does not inherit from nor bear any resemblence to IFX_Font. Review-Url: https://codereview.chromium.org/2036173003

2016-06-02Fix all the code which has duplicate variable declarationsweili
When there are duplicate variable declarations, the inner names shadow the outter ones. This is error prone and harder to read. Remove all the instances found by /analyze. BUG=chromium:613623, chromium:427616 Review-Url: https://codereview.chromium.org/2027273002
2016-05-27Avoid two C-style FX_WCHAR* casts in pdfiumbrucedawson
FX_WCHAR* casts were hiding a number of misuses of narrow strings in pdfium, which /analyze identified. Now that those are fixed I did a search for other instances of (FX_WCHAR*) to see if any other bugs were lurking. No bugs were found but one unnecessary cast and one that should be a const_cast were identified. This change fixes those. No behavioral change. Review-Url: https://codereview.chromium.org/2024463002

2016-05-20Clean up XFA code which causes warningsweili
This is part of efforts to bring XFA to chromium_code standard. The warnings are from unreachable code, or using potentially uninitialized variables, or using assignment within a condition.
