2016-08-30[Merge to M53] Fixup integer conversion logic.chromium/2785Dan Sinclair
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. Merge clean TBRing.

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.

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

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

2016-05-24Remove 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

2016-05-18Pass objects instead of strings for undo/redo records.dsinclair
Currently the Undo/Redo records are serialized as byte strings and stored into a CFX_ByteStringArray. They are deserialized when used. This CL removes the serialization and stores the objects in a deque of unique pointers. Review-Url: https://codereview.chromium.org/1980293004

2016-05-13Make CFX_ByteString(const CFX_ByteStringC&) explicit.tsepez
Add missing helper function to CFX_ByteTextBuf to avoid the anti-pattern CFX_ByteString(sBuf.AsStringC()), using the name "Make" to indicate there's an allocation going on in this case. Change some method arguments to take pre-existing ByteStrings where possible. Review-Url: https://codereview.chromium.org/1977093002

2016-05-12Add CFX_ByteStringC::CharAt() to avoid c_str() and casts.tsepez
Most of the time, we want to operate on chars as if they were unsigned, but there are a few places where we need the default (questionably signed) values. Consolidate the casting in a single place rather than forcing callers to get a char* ptr. BUG=pdfium:493 Review-Url: https://codereview.chromium.org/1972053003
2016-05-12Fix comment in fx_string.htsepez
Previous CLs have removed or marked explicit the constructors which allowed bad constructs to compile. I now get an error: candidate constructor not viable: expects an l-value for 1st argument when called as indicated in the comment. Review-Url: https://codereview.chromium.org/1975983002

2016-04-27Standardize on ASSERT.dsinclair
There are currently three ways to assert in the code (ASSERT, FXSYS_assert and assert). This CL standardizes on ASSERT. The benefit of ASSERT is that it can be overridden if the platform requies and we can pickup the Chromium version if it has already been defined in the build. This does change behaviour. Currently FXSYS_assert is always defined but ASSERT is only defined in debug builds. So, the FXSYS_assert's would fire in Release builds. That will no longer happen. BUG=pdfium:219 Review-Url: https://codereview.chromium.org/1914303003
2016-04-26CFX_ByteString::Reserve(), ReleaseBuffer() fixes.tsepez
Also identical fixes for CFX_WideString. Reserve() on an empty string would not actually reserve a buffer. Currently unused, but there are places where this would really help. ReleaseBuffer() would rarely return memory to the system, since it would short-circuit thinking it could operate in place. Tune the algorithm slightly so that we hold on when the savings is small. Bounds check release buffer args rather than just asserting. Add tests for all of these. Review URL: https://codereview.chromium.org/1916303004
2016-04-25Pass CFX_*StringCs to FX_HashCode_GETA and _GETW hash functions.tsepez
Too many calls were of the form fn(x.c_str(), x.GetLength()) which is an anti-pattern given the StringC classes which tie these together. There are a few places where explicit CFX_*StringCs are constructed, but this can be avoided by changing the args to these functions in the same manner. Removed String_ from name of functions since it added little value. Also removed default argument. Review URL: https://codereview.chromium.org/1919563002
2016-04-22Change the code to avoid three unit test failures on release buildweili
We have three failed unit tests -- FX_AllocOverflow(), FX_AllocOverflow2D(), and FX_TryAllocOverflow() on Linux and Mac release builds, because Clang aggressively optimizes the code. Adding some usage of the return value of a function can avoid the function being optimized away by Clang. Review URL: https://codereview.chromium.org/1915693002
2016-04-21Replace CFX_RectArray with std::vector<CFX_FloatRect>tsepez

2016-04-21Make CFX_BasicArray non-copyable.tsepez
Its implicit copy constructor is unsafe, since it ends up sharing the underlying data. Fix one place where it was being unintentionally invoked. Review URL: https://codereview.chromium.org/1908073003
2016-04-21Assert that CFX_ strings are pointer-size.tsepez

2016-04-20Standalone GN build.dsinclair
This CL setups up a standalone GN build. You'll need to set gn args similar to: use_goma = true clang_use_chrome_plugins = false pdf_enable_xfa = true pdf_enable_v8 = true pdf_is_standalone = true The third_party/pymock files are needed to make git cl upload work correctly.

2016-04-19Remove a few more char* members from structs/classes.tsepez
This is a result of looking for the anti-paterns /char\*\sm_/ and /m_.*=.*\.c_str/ which indicate that a class may be using the contents of a string without extending the lifetime of the underlying storage. Along the way, change to uint8_t in fx_dib; this is unrelated but avoids grep hits (it is binary, not chars anyways). Also remove two string operators that make it easy to assign in a manner that does not extend contents lifetime. Review URL: https://codereview.chromium.org/1902953002

2016-04-14Rename CFX_ByteTextBuf::GetByteString() to AsStringC().tsepez
Do the same for CFX_WideTextBuf as well. The name is confusing because these return CFX_ByteStringC, not CFX_ByteString. The AsStringC naming gives parallelism with the string types themselves, and may help to indicate that the result is only good for the lifetime of the object being operated upon.
