2015-06-09Use stdint.h types throughout PDFium.Tom Sepez
It's redundant nowadays to provide our own equivalents, now that this is done for us by the system header. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1177483002
2015-06-02Fix heap use after free in Document::DoFieldDelay and Document::delayTom Sepez
This fix removes CJS_DelayData object from m_DelayData array and copies them to a new array, before processing them. So contents of m_DelayData array cannot be used after they get freed. BUG=487928 R=tsepez@chromium.org TEST= Chrome pdf plugin should not crash when poc_stable,testuafdocument1.pdf and testuafdocument2.pdf are viewed. see crbug.com/487928 and crbug.com/487928#c18 for more details.

In most cases, we just CHECK() that no exception was thrown. Previously, we'd just crash. Ideally, this should all be fixed and the system should cope with those exceptions, but that's beyond this CL. R=tsepez@chromium.org BUG= Review URL: https://codereview.chromium.org/1126203010

2015-05-14Use phantom handles instead of weak handlesJochen Eisinger
Phantom handles allow for freeing objects with one pass of GC. However, this means that by the time the callback is invoked, the v8 object already does no longer exist. To avoid accidential access to the dead object, there are now two callbacks, where the first must only reset the handle, and the second does the clean-up work.

This allows PDFium to work with current V8, so unpin v8 in the pdfium DEPS file. (I also re-ordered one field in CJS_Runtime, just to put two bools together (may pack tighter), and to put all the v8 stuff together).

2015-04-27Reduce usage of operator LPCWSTR from CFX_WideString().Tom Sepez
This involves adding some explicit c_str() calls. Doing so flagged PDF_EncodeText() and FindOptionValue() as having suboptimal signatures, in that we are often throwing away a perfectly fine length and recomputing it. There are still some platform-specific code that needs the operator. R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1101933003
2015-04-27Revert "Kill operator LPCWSTR from CFX_WideString()."Tom Sepez
This reverts commit 15a62973b9b89c3e229cc0ab501c45967f91b325. Reason for revert: broke build on windows, mac. I must have missed some platform-specific conversions. TBR=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1108883002

2015-04-23Remove unused nParamNum values from JS method tables.Tom Sepez
The code to validate the number of parameters happens inside each particular method, rather than prior to method dispatch. As such, there's no point in having this number take up space in the table. Add some test to cover at least some of the per-method validations, and update error messages to be more useful. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1084183008
2015-04-23Kill overloaded cast operators in CJS_Value.Tom Sepez
The red-flag here is the explicit invocation of things like params[1].operator CFX_WideString() rather than static_cast<CFX_WideString>(params[1]) to invoke the conversion. Turns out the above won't compile due to ambiguity given the number of implicit constructors for widestrings. CJS_Value has both constructors and assignment operators for the primitive types, which means that conversions can take place unexpectedly in both directions, a second red flag. We don't want the compiler invoking these at will since it may hide bugs. In fact, when they are removed, three such places were discovered. Also rename ToJSValue to ToV8Value to match the other ToV8xxxxx functions added. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1096813008

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.

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.

2015-02-05Add 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.

2015-01-05Remove 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.

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.

2014-11-14Change from 'this' to L'this' and remove the cast that was hiding this mismatch.Bo Xu
Found by VC++'s /analyze. Warning was: fpdfsdk\src\javascript\js_runtime.cpp(352) : warning C6276: Cast between semantically different string types: char * to wchar_t *. Use of invalid string can lead to undefined behavior. This mismatch has been there as far back as the history goes (to May of this year). It looks like a real bug to me. However I don't know the implications of this bug and why it would not have been noticed at run-time. The code has been this way as far back as the git history goes, but that is only to May 2014.
