2016-05-03Revert of Relax a couple checks to allow certain non-standard PDF files. ↵weili
(patchset #1 id:1 of https://codereview.chromium.org/1926823002/ ) Reason for revert: Speculatively revert due to high volume of crashes on Chromium.

- CPVT_Size is the same as CFX_PointF - CPVT_FloatRange is unused. - CPVT_ArrayTemplate is just a wrapper for CFX_ArrayTemplate. Review-Url: https://codereview.chromium.org/1919283008

2016-04-29Relax a couple checks to allow certain non-standard PDF files.weili
Some non-standard PDF files misuse the size of cross reference table, and reuse some object number which the old one is still in use. PDFium can relax the reusing of xref objects only since it is not referred in the pdf document. When the size of cross reference table is larger than defined, PDFium will try to continue other than abort. BUG=chromium:596947 Review-Url: https://codereview.chromium.org/1926823002

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.

Review URL: https://codereview.chromium.org/1925453002
2016-04-26Remove several IPDF_ interfaces and CPDF_RenderModule.dsinclair
This CL removes the interfaces: * IPDF_ObjectRenderer * IPDF_OCContext * IPDF_RenderModule * IPDF_PageModule The CPDF_RenderModule was just wrapping new and delete calls. This Cl moves those up to the callers and removes the CPDF_RenderModule class. Review URL: https://codereview.chromium.org/1918323003
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
2016-04-26Clean up CPDF_Page.thestig
- Merge CPDF_Page::Load() into ctor. - Remove always nullptr param for CPDF_Page::ParseContent(). - Remove unneeded indirection in IPDF_RenderModule. - Delete CPDF_ParseOptions. - Fix up CPDF_Pattern. Review URL: https://codereview.chromium.org/1918113002
2016-04-25Fix incorrect offset computation.etienneb
This issue was found by clang-tidy linter. BUG=589955 Review URL: https://codereview.chromium.org/1921713003
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
2016-04-22Add a simple check for V4 cross reference tableweili
Some unknown software generates cross reference table with the claimed object numbers are all off by one. Add a simple verification function to detect this scenario, thus have a chance to rebuild the correct cross reference table. To avoid unnecessary checks and potiential performance hit, we only check for the very first non free entry. BUG=602650 Review URL: https://codereview.chromium.org/1910063004
2016-04-22Remove #ifdef platform which is always true.tsepez

2016-04-21Remove one warning from PDFium compilation in Crosweili
The original code caused an optimization warning when gcc tries to get rid of 'count > m_Length - index' in CFX_ByteStringC::Mid() while assuming there is no signed integer overflow. This could also be avoided once FX_STRSIZE is no longer a signed integer type. Review URL: https://codereview.chromium.org/1906213002

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

2016-04-21Only call shading code with streams.dsinclair
There are 4 types of meshes that attempt to convert the shading object into a stream. According to spec (section 8.7.4.1 table 76), the shading object can be a stream or a dictionary. All of this shading code assumes it can load the mesh from a stream. The original code just early exited if it was not a stream. We skip the call if it is not a stream.

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.

Remove one left warning from GN Release build. Review URL: https://codereview.chromium.org/1904473003
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
2016-04-19Remove IPDF_TextPage, IPDF_TextPageFind and IPDF_LinkExtract interfaces.dsinclair

2016-04-14Avoid string allocs for CMap_GetString() return value.tsepez

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.

2016-04-14Make CPDF_ApSettings take CFX_ByteString args.tsepez
These are immediately used to access a dictionary, so the use of static CFX_ByteStringCs may force duplicate allocations. BUG= Review URL: https://codereview.chromium.org/1888893002
2016-04-14Make CPDF_Dictionary methods take CFX_ByteString argumentstsepez
This will help avoid duplicate allocation of CFX_ByteStrings when the caller already has one. It may seem counter-intuitive that requiring the caller to pass an allocated CFX_ByteString rather than a static CFX_ByteStringC would improve the situation, but due to the idiosyncrasies of std::map, the CPDF_Dictionary methods must always do an allocation under the covers which can't be avoided. The changed callers in this CL are places where we would previously demote to CFX_ByteStringC and then allocate a a duplicate CFX_ByteString in the dictionary method.
