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.

2015-01-22Fix build of pdfium_embeddertest under V8_USE_EXTERNAL_STARTUP_DATA.Tom Sepez
Currently, this is a difference between the standalone pdfium environment vs. pdfium as part of a chromium checkout. Locating the external data files is a nusiance when you don't have the binary's argv[0] line, so we create a new main that preserves this for us.

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. After converting callers away from using the CPDF_DataAvail concrete class, it can be moved from the header to the .cpp file.

Follow-on work from patch at https://codereview.chromium.org/845643008. This incorporates that patch, plus adds tests for it and similar conditions. A few changes are introduced to correct expected behaviour. This also incoprorates Deepak's fix in https://codereview.chromium.org/845643008/ This incorporates a formerly unlanded tool to generate small valid PDF files from template input, which is needed to cover all the error cases here.

This was somehow lost along the way to creating embedder tests. Presumably this silently leaks in origin/master, but triggers an assert under XFA.

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.

2015-01-09Fix -Wnon-virtual-dtor compiler warnings.Tom Sepez
This is done by explicitly adding a virtual dtor to interface classes, since the cost is small given that there are already virtual functions. The exceptions are for classes that have a Release() or Delete() method, in which case it is non-virtual and protected to indicate that the virtual class is never the deletion point.

2015-01-06Resolve all but two VC++ build warnings in pdfium.Bruce Dawson
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.

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.

2015-01-05Remove 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).

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.
