2015-03-10Kill remaining sprintfsTom Sepez
I thought I had done this already, apart from the third-party libraries, but there were a couple remaining (the third-party libraries will still call this, they should be tweaked upstream as needed). R=thestig@chromium.org Review URL: https://codereview.chromium.org/999543002
2015-03-06Make conversions for CPDF_Link explicit.Tom Sepez
Precursor to taking a second shot at cleaning up the FPDF_* APIs. A FPDF_LINK is a CPDF_Dictionary, and a CPDF_Link is a structure holding a FPDF_LINK. This goes against the convention that FPDF_ types get cast to CPDF_* types, so we want to make it clear where objects are getting constructed.

2015-03-06Make conversion between CPDF_Dest and its object explicit.Tom Sepez
Precursor to taking a second shot at cleaning up the FPDF_* APIs. A FPDF_Dest is a CPDF_Array, and a CPDF_Dest is a structure holding a FPDF_Dest. This goes against the convention that FPDF_ types get cast to CPDF_* types, so we want to make it clear where objects are getting constructed, etc. R=thestig@chromium.org Review URL: https://codereview.chromium.org/984703004
2015-03-05Make conversion between CPDF_Action and its dictionary explicit.Tom Sepez
Precursor to taking a second shot at cleaning up the FPDF_* APIs. A FPDF_Action is a CPDF_Dictionary, and a CPDF_Action is a structure holding a FPDF_Action. This goes against the convention that FPDF_ types get cast to CPDF_* types, so we want to make it clear where objects are getting constructed, etc. Also tidy fpdf_actionhandler.cpp because it bugs me.

2015-03-02Kill off JS_ErrorString type.Tom Sepez
This provides no benefit, and reduces transparency. Along the way: Kill off some unused/commented-out code. Return void where a bool return doesn't make sense. Remove a pointless template type. Remove now unused constants and types. R=thestig@chromium.org Review URL: https://codereview.chromium.org/971033002
2015-03-02Return error information from pdfium to JS.Tom Sepez
This implements the previously unimplemented JS_Error() function. Along the way: - fix some IWYU when the include order in global.cpp was perturbed. - remove some uses of JS_ErrorString, to increase transparency. - use vp.IsSetting() in place of !vp.IsGetting() for clarity. - specify an error string on several error return paths. - add an error string for writing readonly properties. - rename an error string constant to reflect the actual message. - replace calls to variadic Format() with a function doing string appends. - remove unused JS_GetClassName() R=thestig@chromium.org Review URL: https://codereview.chromium.org/963193003
2015-02-27Remove unused IDS_ constants from pdfium.Tom Sepez
Along the way, I noticed that one of these is used in a header file that isn't included anywhere and describes no actual code (JS_Console.h). Also add missing header guards, and IWYU to resources.h Also move a static function from a header to the new resources.cpp file. Also fix the grammar on some of the error messages. Most of these appear to be JS error messages destined for a JS error handler or (someday) a console (which can remain in english), and oddly, some appear to be about failed form validation, which smells user-facing. Also check that the message makes sense for the point the C++ code wants to use it, and reword accordingly. As it turns out, these currently don't make it back to JS due to the unimplemented JS_Error() function; this is an enabling step towards implementing it.

2015-02-27Pull in gmock for standalone pdfium builds.Tom Sepez

2015-02-25Kill off unused IFXJS interface methods.Tom Sepez
Re-work of original CL at: https://codereview.chromium.org/933043002/ Much of the IFXJS interface appears completely unused, so Kill off unused IFXJS interface methods. The code itself appears incomplete against all of the objects present in the paths that actually do register objects with JS.

2015-02-17Tidy up JS_Defines.hTom Sepez
This is a purely mechanical change, no new functionality. - Expand some macros which were merely a short-cut to save typing but reduced transparency. - Put GET_VALUE_TYPE() implementation into a .cpp file.

2015-02-05Fix segv in CPDF_DataAvail::CheckRoot() when /Root object is a string.Tom Sepez
Handles the case of this malformed PDF without crashing. Note that to get a reproducible test case, a small fix is applied to our .py script which results in some whitespace/numbering difs across the resources (down the road, we ought to generate them on the fly in an intermediate directory).

2015-02-05Add namespace and-re-arrange PDFium's local copy of chromium /base.Tom Sepez
Any projects DEPS'd into chromium and requiring a /base subset should have a local copy of that subset in a separate namespace. This will avoid future naming conflicts. Re-arrange the directory structure to better identify what came from chromium's base, and to make drop-in replacement easier for files that contain hard-coded "base/" in their #include directives.

2015-01-26Fix infinite recursion in CPDF_Parser::ParseIndirectObjectAt().Tom Sepez
A suitably corrupted file can cause the parser(s) to repeatedly re-read sections of the file at increasing parser recursion depth until the stack is exhausted. There is supposed to be a check for this based upon the parser "level", but not all call paths pass or update the level as required. Much as I hate per-class statics, this introduces one to track the depth so that the check is enforced no matter how screwy the call path might be that leads the parser to re-enter itself. This is more palatable than trying to find all these paths and fix them. We know this is OK since there is only one thread in here modifying the static.

2015-01-22Use IPDF_DataAvail interface to hide CPDF_DataAvail.Tom Sepez
Currently, no callers go through the Interface, which makes having a separate interface class kind of pointless.

This is done by explicitly adding a virtual dtor to interface classes, since the cost is small given that there are already virtual functions.

2015-01-05Remove run-time calculation of hash constants in pdfium.Bruce Dawson
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). BUG=441899 R=tsepez@chromium.org Review URL: https://codereview.chromium.org/792043005
2015-01-05Get rid of fifteen copies of m_sTimeMap and their initializers.Bruce Dawson
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.

2015-01-05In windows printing, convert src bitmap to dest bitmap using CompositeBitmap.Bo Xu
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. BUG=412908 R=vitalybuka@chromium.org Review URL: https://codereview.chromium.org/826633002
2015-01-02Remove g_NaN global variable and its constructor.Bruce Dawson
Doing the type conversion on demand is just as efficient as doing it at startup time, and makes for more efficient startup.

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).

2014-12-08Replace manual/error-prone/hard-to-verify arraysize calculations with safe ↵Bruce Dawson
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.

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.
