2015-01-05Fix an array size mismatch.Lei Zhang
The g_UnicodeData_Normalization_Map2 array is initialized with a size of 1724 in core\src\fpdftext\unicodenormalizationdata.cpp but its size is 1734 (+10) in core\src\fpdftext\unicodenormalization.cpp, 1724 seems to be the real size (i.e. there's 1724 values in the initialization list).

2014-12-29Create pdfium_unittests binary.Tom Sepez
PDFium has not yet had a unit-tests binary, so introduce one based on the typical gtest framework. Also provide a small initial test fragment for fxcrt strings for instructional purposes. Naturally, doing so kicked out one corner case that isn't handled, we'll fix that in a separate patch. This is a small part of the testing strategy tracking bug.

2014-12-19Update freetype to 2.5.4.Bo Xu
Put freetype into third_party directory, cleaning up header files. Previously freetype header files are in core/src/fxge/freetype and core/include/thirdparties. There were also multiple fx_freetype.h. This patch removes the additional Foxit wrapper to make further update easier. Notice, for original freetype source code, the following files are modified and need to be updated accordingly in future update: third_party/freetype/include/config/ftmodule.h third_party/freetype/include/config/ftoption.h BUG=407341 R=thestig@chromium.org Review URL: https://codereview.chromium.org/815103002

This reduces rendering time on my test document by over 10 seconds.

2014-12-12Avoid duplicate definitions of JSCONST_n*Hash and QeTable variables.Bruce Dawson
QeTable is a 752 byte array that was defined in a header file. This caused it to be instantiated by the VC++ compiler 12 times, wasting 8,272 bytes of space in the data segment. Because 'const' implies 'static' this did not cause any duplicate symbol errors. JSCONST_n*HASH are a set of eight variables that are defined in a header file. This causes them to be replicated 15 times. The variables themselves are tiny but they are dynamically initialized and this dynamic initialization code is replicated 15 times. When tested on pdfium_test.exe the effect of this change is to: Reduce the .text (code) segment by 3,616 bytes. Reduce the .rdata section by 8,656 bytes. Reduce the total binary file size by 13312 bytes. These are the worst offenders for pdf.dll as shown in: https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0 This will also drastically simplify the list of work to be done for bug 441899 (getting rid of initializers).

2014-12-08Getting rid of more (FX_LPCWSTR) casts and fixing two bugs revealed by this.Bruce Dawson
Since casts to FX_LPCWSTR have been shown to hide bugs I tried removing more of them, targeting those places where a cast was used to force a conversion from CFX_WideString to FX_LPCWSTR, replacing these casts with calls to the newly added .c_str() function. This revealed two places where the cast was hiding a bug -- where ->c_str() was required instead! This removes ~33 FX_LPCWSTR casts and there are ~31 left, many of which will go away in some future change. Also includes this change: Removing unnecessary casts from wchar_t* to wchar_t*, by various names.

Before this fix, PDF parser aborts the parsering process when detecting an error. For this case, PDF parser just gives up parsering when it detects that the length of image stream is incorrect. The solution to this case is to find the tag "endstream" and "endobj" to calculate the length rather than aborting the parsering process.

2014-11-17Removing unnecessary casts from wchar_t* to wchar_t*, by various names.Bruce Dawson
Remove casts that merely cast from wchar_t* to wchar_t*. Sometimes the types or casts are FX_LPCWSTR but the idea is the same. Excess casts can (and have) hidden bugs so removing these may prevent future problems.
