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

2015-04-14Kill CFX_Object.Tom Sepez
CFX_Object is a type that implements its own new operators that return NULL on error. There's no need for this given the |new (std::nothrow)| syntax; in fact, the current code can only work if there is no activity in the constructors. This may explain the pervasive lack of constructors and reliance on Init() methods throughout the codebase. The activity takes place in fx_memory.h, where FX_NEW is mapped onto the std::nothrow syntax. The rest is just cleanup. Down the road, we will simply throw and remove all the error-checking paths for new objects. Landing this patch first will at least show a simple path back to the old behaviour without having to re-introduce CFX_Object should someone want to do so in their own fork.

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.

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.

2014-10-14Store the address of the page data map's value for proper referencing.Bo Xu
CPDF_Pattern objects are counted and maintained in m_PatternedMap. When a CPDF_Pattern object "pattern" is deleted, it's address is marked as NULL in m_PatternMap. This patch stores the address of CPDF_Pattern's adderss in all objects that references "pattern", to ensure valid referencing after deletion.

2014-08-13Add FX_OVERRIDE and use it for virtual functions of FX_FINAL classes.Tom Sepez
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. The only issues were with CPDF_CustomAccess::GetBlock(), CPDF_CustomAccess::GetByte(), and CPDF_CustomAccess::GetFullPath(). These don't appear to be used anywhere, and are removed. Two members are removed that are no longer needed once those methods are removed. R=jam@chromium.org, jun_fang@foxitsoftware.com Review URL: https://codereview.chromium.org/454983003

Patterns are managed in CPDF_DocPageData. When a document is closed, all patterns will be released in the deconstruction of CPDF_DocPageData. However, some patterns which are referenced in CPDF_Color can't get the notification from the destroy of CPDF_DocPageData. It will cause use-after-free in CPDF_Color::~CPDF_Color.

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.
