2015-02-05Merge to master: Kill off some dodgy JS callbacksTom Sepez
Note that this work was done opposite the usual branch order, because I didn't want to kill things in master that turned out to be in use in XFA. Original Review URL: https://codereview.chromium.org/883393007 TBR=jam@chromium.org Review URL: https://codereview.chromium.org/903893002
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.

2015-02-04Prevent base::CheckedNumeric from leaking outside of pdfium.Tom Sepez
Headers in /include directories should be free of implementation details from third_party. Put the types into a new header outside of /include.

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

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.

Before this fix, PDF parser aborts the parsering process when detecting an error. For this case, PDF parser just gives up parsering when it detects that the length of image stream is incorrect. The solution to this case is to find the tag "endstream" and "endobj" to calculate the length rather than aborting the parsering process.
