2016-06-27Double AdobeCMYK_to_sRGB speed with faster roundingbrucedawson
FXSYS_round is painfully slow on Windows. It does range checking and then calls an extremely expensive function. It ends up consuming half the CPU time when decoding the images in PDFs such as this one: https://www.ets.org/Media/Tests/GRE/pdf/gre_research_validity_data.pdf SSE can be used to optimize this: __m128 cmyk = {c * 255, m * 255, y * 255, k * 255}; uint32_t output[4]; _mm_storeu_si128((__m128i*)output, _mm_cvtps_epi32(cmyk)); but is cryptic, only works for x86/x64, and gives basically identical performance to this solution - int(c * 255 + 0.5f); The rounding behavior is not identical but in practice this rarely matters, and in this specific case it does not matter because the edge cases that vary are not hit. The three divisions at the end were changed to multiplies because profiling showed they were a significant cost. This change reduces the image-decode stalls in the PDF listed above by about 40%, making for a noticeably better experience. Further optimizations are possible but would require significantly more time and testing. BUG=617365 Review-Url: https://codereview.chromium.org/2096723003

See https://codereview.chromium.org/2076483002 for a lengthy reasoning. The two mysterious files called out there were in boringssl and nacl, so for pdfium this should be a complete no-op. BUG=chromium:592745 Review-Url: https://codereview.chromium.org/2096143002

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
2016-06-23Pass needed value to CXFA_Node constructordsinclair
Currently the CXFA_Node constructor will call out to lookup the object type for a given element type. There is only one called of this constructor and it already has the object type so just pass it through instead of getting the element data a second time. Review-Url: https://codereview.chromium.org/2092853002

This CL converts all NULL's to nullptr. All instances of comparison to nullptr have been removed. Review-Url: https://codereview.chromium.org/2095653002
2016-06-23Change XFA_GetElementByName to XFA_GetElementTypeForNamedsinclair
This method was only ever used to get the XFA_Element type for the given element name. Changed to make the signature match the usage. Review-Url: https://codereview.chromium.org/2095733002

2016-06-23Load font maps in XFA.dsinclair
When XFA is enabled documents using some unicode fonts will render incorrectly as seen in the example attached to chromium:617490. This CL enables the loading of the font map files in XFA so we can correctly identify the character sets as unicode and map the glyphs correctly.

2016-06-23Remove FPDFAPI_LoadCID2UnicodeMap.dsinclair

2016-06-23Remove IsOrdinaryList; rename to OrdinaryList to Listdsinclair
IsOrdinaryList is no longer used, removed. Rename list item as Ordinary doesn't hold any meaning. Review-Url: https://codereview.chromium.org/2079393006
2016-06-23Remove CXFA_OrdinaryObject classdsinclair
The CXFA_OrdinaryObject class no longer has any functionality but is just wraps CXFA_Object and sets the object type for the sub classes. This Cl removes the class and has the subclass set the object type themselves. This CL also renames the OrdinaryObject type to just Object. Review-Url: https://codereview.chromium.org/2082343003
2016-06-22Update GetClassID to GetElementTypedsinclair
The GetClassID method actually returns the XFA_Element, change the name of the method to be more suggestive of the return value. The GetClassID was sort-of polymorphich and would call down to subclasses. This CL changes the data to be stored on the CXFA_Object class and just returns what is set. The values are set in the constructor as needed. Review-Url: https://codereview.chromium.org/2082573007

2016-06-21Update the documentation: no longer needs to set clang_use_chrome_pluginsweili
PDFium can be compiled with clang_use_chrome_plugins=true, which is the default setting. So we no longer need to set the variable. BUG=pdfium:469 Review-Url: https://codereview.chromium.org/2085803003

2016-06-20Split the XFA_OBJECTTYPE enum into two parts.dsinclair
Currently the object type and the node flags are both mixed into the single XFA_OBJECTTYPE_* enum. These two things are un-related and should not share a single type. This Cl creates an XFA_ObjectType enum class and a XFA_NodeFlag enum to hold the two types. Accessors are added to determine if the flags are set (or called where they already existed.

2016-06-20Fixup LoadImageInfo type checking.dsinclair
The ::DetectImageType method does more then just detecting the image type, it also sets up various needed structures to handle the decoding. Instead of skipping the ::DetectImageType call this CL changes the code to return early if the image check fails. This should allow us to stop working on images which do not match the required data format. BUG=chromium:621094 Review-Url: https://codereview.chromium.org/2085493002
2016-06-20Speculative fix for FXJS_InitializeRuntime crash.dsinclair
The call to GetGlobalObjectTemplate() in FXJS_InitializeRuntime() will call into CFXJS_ObjDefinition::MaxID() which will call FXJS_PerIsolateData() on the provided isolate. We, currently, create the isolate data after we make this call which seems like it would lead to bad things. This CL moves the PerIsolate data creation earlier in the process.

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
