2016-09-28Implement weak pointerschromium/2876chromium/2875tsepez
These will be a replacement for CFX_CountRef in future CLs, since CFX_CountRef is manually incremented and error-prone. Review-Url: https://codereview.chromium.org/2377143002
2016-09-28Revert "Rename CPDF_CountedObject to CFX_WeakPtr::Handle"tsepez
This reverts commit fe0179ded8202939ea4f2b92a879b8dede7821ea. This is blocking incremental revision, will try again. Review-Url: https://codereview.chromium.org/2377033003
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
2016-09-22Null CPDF_CountedObj::m_pObj prior to deletiontsepez
This gives additional protection in case of re-entry. Also make CFX_CountRef more robust in face of errors. BUG=649229 Review-Url: https://codereview.chromium.org/2364673002
2016-09-15Add string pools to save storage.tsepez
Adds string hashes so CFX strings will interoperate with STL unordered containers. These will be employed per-document in a subsequent cl. BUG=pdfium:597 Review-Url: https://codereview.chromium.org/2341683005
2016-09-15Add short-cut in CFX_{Byte,Wide}String::Operator<()tsepez
Strings are never less than themselves, and this will occur given the shared CoW nature of these strings. Review-Url: https://codereview.chromium.org/2347433004
2016-09-14Cleanup CPDFXFA_Document.dsinclair
Remove unused params and methods. Cleanup formatting. Review-Url: https://codereview.chromium.org/2322003002
2016-09-13Add check for trivial string equalitytsepez
BUG= Review-Url: https://codereview.chromium.org/2338623005

Review-Url: https://codereview.chromium.org/2341453002
2016-09-12Make CFX_Obeservable::Observer into a pointer-ish type;tsepez
This may be a better design because it avoids having a level of indirection that the Observer required. Review-Url: https://codereview.chromium.org/2326763002
2016-09-08explicit operator bool for CFX_RetainPtr and CFX_CountRefchromium/2855tsepez
Review-Url: https://codereview.chromium.org/2324733003
2016-09-08Replace CJS_Runtime::Observer with CFX_Runtime<CJS_Runtime>::Observertsepez
Previously, the observer set a flag which conditionalized a null pointer return. Now, we just clear the pointer. Destruction order matters, so add a method to trigger notifications. Review-Url: https://codereview.chromium.org/2322743002
2016-09-07Make Observers into a templated classtsepez
Review-Url: https://codereview.chromium.org/2311343003
2016-09-02Make CPDF_ClipPath have a CPDF_ClipPathData rather than inheriting.tsepez
Make Data private to the ClipPath class which manages it transparently for its callers. This prevents the callers from having to remember to make a copy before dirtying the shared data, since the operations that modify state will do this under the covers for us. Review-Url: https://codereview.chromium.org/2301263003
2016-09-02Remove CFX_Matrix::Copy() in favor of assignmenttsepez
The default assignment operator will suffice and allows us to write matrix1 = matrix2; Review-Url: https://codereview.chromium.org/2307953003
2016-08-30Make CPDF_TextState have a CPDF_TextStateData rather than inheriting one.tsepez
Review-Url: https://codereview.chromium.org/2287313004
2016-08-30More better const-ness in CFX_CountRef<>tsepez
There are a couple of places where code is calling GetObject() that should be calling GetPrivateCopy(), but works because the value may not be shared at the time. This just makes it safer. Review-Url: https://codereview.chromium.org/2290863002
2016-08-29Revert "Add -> operators to CFX_CountRef."tsepez
This reverts commit c10c23a2b1999b1cb0354fd4db9837dc63a3d833. TBR=dsinclair@chromium.org Review-Url: https://codereview.chromium.org/2285283003
2016-08-26Add -> operators to CFX_CountRef.chromium/2842tsepez
Allows CFX_CountRefs to behave more like pointers. Rename SetNull() to Clear() for consistency with other ptrs. Change GetPrivateCopy() into MakePrivateCopy() with no return, since the -> operators are clearer than getting an object pointer. Review-Url: https://codereview.chromium.org/2283113002
2016-08-26Make CFX_CountRef<>::m_pObject private, add accessors, fix const-ness.tsepez
Hide the CountedObj class from the rest of the code. Rename GetModify() to GetPrivateCopy(), since it turns out there are places where we modify a potentially-shared copy. Add non-const version of GetObject() to permit these. Review-Url: https://codereview.chromium.org/2287633002
2016-08-26Remove CFX_CountRef::IsNull in favor of operator booltsepez
Review-Url: https://codereview.chromium.org/2285513002
2016-08-26Rework CFX_CountRef in terms of CFX_RetainPtr.tsepez
Make use of existing ref count work rather than re-inventing it. Review-Url: https://codereview.chromium.org/2281683002

2016-07-27Fixup integer conversion logic.chromium/2813chromium/2812chromium/2811dsinclair
In bc8a64029f898286c3dcad3a6cecdc98ef30b139 we updated the FX_atonum logic to correctly handle integer overflow. This causes issues when parsing the Permissions flag of encrypted documents as that flag isn't encoded like other numbers. The Permissions flag is a unsigned value, and has to be treated as such since the sign bit is always set. The current logic will detect an overflow of the int value and return 0. The old logic would have detected the overflow and returned the negative result regardless. This CL updates the logic to do the string to int conversion as a uint32_t and then verifies the uint32_t value, if a sign was provided, fits within the int range, otherwise it converts it to an int and lets it be positive or negative as needed.

2016-07-24Remove CFX_Deletableweili
Change the last use of CFX_Deletable to its actual type and remove the use of CFX_Deletable. Review-Url: https://codereview.chromium.org/2178613002
2016-07-21Use smart pointers for graphics device classesweili
Use unique_ptr for class owned member variables. Also clean up some style issues such as removing unused functions and casting to raw pointer. BUG=pdfium:518 Review-Url: https://codereview.chromium.org/2163103002
2016-06-23Improve hint table validation checks.thestig
Check required hint table dictionary entries and make sure they: - Exist. - Are of the right type. Along the way: - Fix FX_atonum() to not have a non-const pass-by-ref param. - Simplify code in CPDF_StreamContentParser. - Make CPDF_Number::IsInteger() a const method. BUG=610555 Review-Url: https://codereview.chromium.org/2095763003
2016-06-23Use some FXSYS methods instead of duplicatingdsinclair
This CL uses the FXSYS_isDecimalDigit in place of a few custom IsDigit methods. It also creates an iswspace and some fractional math helper methods to share some code. Review-Url: https://codereview.chromium.org/2094453004
2016-06-20Change func(void) to func()weili
Since PDFium is compiled as C++ code, the void keyword is not needed. BUG=pdfium:519 Review-Url: https://codereview.chromium.org/2084603003
2016-06-14Make code compile with clang_use_chrome_plugin (part II)weili
This change contains files in core directory which were not covered in part I. This is part of the efforts to make PDFium code compilable by Clang chromium style plugins. 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/2060913003

Review-Url: https://codereview.chromium.org/2053513002
2016-06-08Remove implicit CFX_CountedRef::operator T*()tsepez
Explicitly invoke GetObject() method instead. This avoids having code where it looks like non-pointers are assigned to pointers but works due to the cast operator. Review-Url: https://codereview.chromium.org/2045083003

2016-06-07Fix more code which has shadow variablesweili
The code has local variables that shadow struct or class member variables. Also, when this happens, different variable names should be used instead of namespaces. These were discovered by /Wshadow warning flag in Clang. Review-Url: https://codereview.chromium.org/2034253003

2016-05-25Banish CFX_PrivateData to the XFA sidetsepez
Remove an unused inheritance. The remaining usages are a little more intricate. Review-Url: https://codereview.chromium.org/2015743002
2016-05-24Remove CFX_PrivateData from CPDF_ModuleMgrtsepez
Its only used to store one object, so replace it with a unique_ptr to a class with a virtual dtor. Rename the prototypical class with virtual dtor from CFX_DestructObject to CFX_Deletable. Rename the fx_basic_module.cpp to cfx_modulemgr.cpp to match the one class in it. Review-Url: https://codereview.chromium.org/2013483003
2016-05-23Rename IFX_Unknown to IFX_Retainable.tsepez
Rename addRef() method to Retain() to match Release(). This CL does not convert to CFX_RetainPtrs, which will happen in a follow-on. Review-Url: https://codereview.chromium.org/2005933002
2016-05-20Use enum type for char type variablesweili
