2015-01-09XFA: merge patch from CL 839163002 to only request C++ 11 for C++Bruce Dawson
Only request C++11 when compiling C++ code. Linux pdfium builds have 215 warnings of this form: command line option -std=gnu++11 is valid for C++/ObjC++ but not for C The obvious fix is to not request C++11 for C compilations. The only complication was the the switch we are using is actually gnu++0x, not gnu++11.

2015-01-08XFA: merge patch from CL 792953005, fix most warningsBruce Dawson
Includes fixes to XFA specific warnings -- benign truncations. Bug https://code.google.com/p/pdfium/issues/detail?id=104 was filed to track changing types to avoid some truncations. Resolve all but two VC++ build warnings in pdfium. pdfium builds on Win32 have about 85 warnings (250 in the XFA branch, totaling over 480 lines!), mostly from four lines in a header file and a warning that should be disabled. This change resolves all but two of them and turns on warning-as-errors. Bugs have been filed for the two remaining warnings: https://code.google.com/p/pdfium/issues/detail?id=100 the 64-bit warnings: https://code.google.com/p/pdfium/issues/detail?id=101 and the Linux warnings: https://code.google.com/p/pdfium/issues/detail?id=102 The fix to the double->float truncation bugs will also improve code-generation.

2015-01-05XFA: merge patch from CL 832703003, remove g_timeMap globalBruce Dawson

2015-01-05XFA: merge patch from CL 792043005, run-time hashing.Bruce Dawson
Remove run-time calculation of hash constants in pdfium. PDFium static initializers must go. Static initializers are prohibited by the style guide. They have negative consequences including increased startup time (from pulling in additional code pages) and reduced sharing of data pages (since the variables can't go in the read-only data segment). This change uses a template struct and typed enums to reproduce JS_CalcHash at run-time. An unsigned long long constant and masking with 0xFFFFFFFF are used to avoid compile errors due to integer overflow of compile-time constants. The HashVerify class is used to check the results, necessary since none of the functions in global.cpp are called when pdfium_test.exe runs. const_expr would be a much cleaner way to implement this change but it is not yet widely supported. On the Windows release build this reduces the code size (.text virtual size) by 0x240 (576) bytes, the .data section by 0x20 bytes (for eight unsigned globals), and the .rdata section by 0x20 bytes (the unneeded string savings, minus the eight unsigned globals now being there).

2015-01-05XFA: merge patch from CL 831903002, m_sTimeMap fixesBruce Dawson
Get rid of fifteen copies of m_sTimeMap and their initializers. m_sTimeMap is a global variable with a constructor and destructor, which is not allowed. This change moves it to a function with a static pointer so that it is constructed on demand and then leaked, thus avoiding having startup and shutdown code. This also fixes a worrisome bug caused by having m_sTimeMap defined in a header file. Because m_sTimeMap was defined (and marked as static) in a header file there were fifteen separate copies of it, one for each source file which included the header file. This could easily lead to bugs because a timer that was added from one source file would be invisible to other source files. Each instance of m_sTimeMap added four entries to the dump-static-initializers.py report, for a total of sixty, so this fix significantly cleans up that report.

2015-01-05XFA: merge patch from CL 729293003, use FX_ArraySize for safetyBruce Dawson
Note that the merge of this fix to XFA found six bugs. Five were fixed in https://codereview.chromium.org/826573003 and one was fixed in https://codereview.chromium.org/831293002. These bugs are now impossible to compile. Replace manual/error-prone/hard-to-verify arraysize calculations with safe FX_ArraySize macro. pdfium has numerous places where the number of elements in an array is calculated with expressions like: sizeof(cFormats)/sizeof(FX_LPCWSTR) This is suboptimal because it is verbose, it is easy to get wrong, and it cannot be determined through casual inspection whether the code is correct. It will give incorrect results if cFormats is a pointer instead of an array and it will give incorrect results if FX_LPCWSTR is not the type of the array elements. The FX_WSTRC macro in fx_string.h which I fixed was particularly scary because it would silently misbehave if passed a pointer. The FX_ArraySize macro which I have added and started using (taken from arraysize in v8's macros.h) is easier to use and will always give correct results. If passed a pointer it will fail to compile. For this change I only fixed instances of sizeof(FX_LPCWSTR). There appear to be about 150 other places in the pdfium code that could benefit from using FX_ArraySize.

2015-01-05Fix one remaining misuse of FX_WSTRC on FX_WCHAR* vars.Bruce Dawson
FX_WSTRC is only valid on arrays, not pointers. In this code it was being passed a pointer to a URL. This was found when integrating a change to FX_WSTRC that disallows pointer arguments. The consequence of this bug is that the URL will end up with incorrect lengths. It will be one character long in 32-bit builds, and three characters long in 64-bit builds (sizeof(WCHAR*)-1).

In windows printing, convert src bitmap to dest bitmap using CompositeBitmap. When dealing with transparency, the printing procedure will generate a bitmap first, then draw this bitmap in windows DC. The format of source bitmap is argb, but the destination bitmap is rgb. Simply doing memcpy will lose the alpha channel information, so CompositeBitmap function is needed.

2015-01-05Fixed incorrect use of FX_WSTRC on FX_WCHAR* vars.Bruce Dawson
FX_WSTRC is only valid on arrays, not pointers. In five places it was being passed a pointer, which leads to incorrect string objects being created. This was found when integrating a change to FX_WSTRC that disallows pointer arguments. The consequence of this bug is that five XML strings (quot, amp, apos, lt, and gt) will all end up with incorrect lengths. They will all be one character long in 32-bit builds, and three characters long in 64-bit builds (sizeof(WCHAR*)-1). Also removed some unneeded casts and marked some arrays as const. Fixing this is necessary in order to allow landing of https://codereview.chromium.org/818193004/ Testing this was attempted by using the xfa branch of pdfium in Chrome: cd third_party\pdfium git checkout xfa However even without these changes this caused a CHECK failure in V8::InitializePlatform due to double initialization, so the fix has not been tested, but is clearly an improvement.

2014-12-23XFA: merge patch from CL 733693003, getting rid of more castsBruce Dawson
Getting rid of more (FX_LPCWSTR) casts and fixing two bugs revealed by this. 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.

2014-12-19XFA: merge patch from CL 441988Bruce Dawson
Avoid duplicate definitions of JSCONST_n*Hash and QeTable variables. 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).
