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.

2015-01-05Get 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.

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.

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.

2014-11-06Adding constructor to _FX_SYSTEMTIME to resolve uninitialized read bugs ↵Tom Sepez
found by /analyze on some error paths Warning from /analyze was: src\third_party\pdfium\fpdfsdk\include\fsdk_mgr.h(96) : warning C6001: Using uninitialized memory 'fxtime'. Other error paths can also lead to reading from an uninitialized _FX_SYSTEMTIME object. Code-gen for the constructor is small enough (four writes of zeroed EAX with VC++, less with gcc) to make putting the constructor in a .cc file unnecessary. Approval of in-class member initialization would make this fix simpler but that has not quite been approved yet.

Should there be cases where this fails to compile, it indicates a mistake, either an incorrectly declared overrriden virtual method, or a method that should be declared non-virtual.

2014-07-30Speculative fix for uninitialized value in CFX_ByteString().Tom Sepez
If somehow different length values could be obtained by two successive calls to Doc_getFilePath() (and FieldBrowse() for that matter), and the method is true to the API documentation that says "The return value always indicated number of bytes required for the buffer, even when there is no buffer specified, or the buffer size is less then required", then it is possible to get a returned length describing memory beyond the current buffer. We can make the corresponding JS_docGetFilePath() method more robust against this case by applying better checks to the returned value. This probably is unrelated since ASAN seems to be flagging the corresponding bug as UAF, but doesn't hurt to make things more robust.

2014-07-18pdfium: Fix all -Wdelete-non-virtual-dtor violations on Mac.Nico Weber
Calling `delete` on an object of a type that has virtual functions but not a virtual destructor is questionable: Since the object has virtual functions, it likely has subclasses, so if it's deleted through the base pointer and the destructor isn't virtual, the subclass destructor won't be called. In most cases, the classes getting deleted can just be marked final to tell the compiler that it can't possibly have subclasses (this also enables the compiler to generate better code). Two classes didn't have any sub- or superclasses but virtual functions - this doesn't make sense, so make all methods of these classes non-virtual. (Also delete an unused function on one of the two classes.) In one case, a class actually did have a subclass that needs to be deleted virtually, so mark one destructor as virtual.
