2017-08-23Convert string Find methods to return an OptionalRyan Harrison
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.

2017-08-01Replace raw value for constant error value in string operationsRyan Harrison
Currently Find() and other methods that return a FX_STRSIZE return -1 to indicate error/failure. This means that there is a lot of magic numbers and magic checks floating around. The standard library for similar operations uses a npos constant. This CL implements FX_STRNPOS, and replaces usages of magic number checking. It also does some type cleanup along the way where it was obvious that FX_STRSIZE should be being used. Removing the magic numbers should make eventually changing FX_STRSIZE to be unsigned easier in the future.

2017-05-20Use observed ptrs from CFGAS_GEFont back to its font mgrs.chromium/3106Tom Sepez
CFGAS_GEFonts are ref counted, and its a good thing since they are managed by at least three different font managers: CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these have a clear claim to ownership of the CFGAS_GEFont. CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and CXFA_PDFFontMgr, and they could each outlive the other. Thus the font needs to watch for destruction of either of its managers, so as to stop using it after its gone.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.

2017-01-17Avoid endless loop deleting CFGAS_GEFont.tsepez
It's a ref-counted class, so if we're in the destructor, the ref count has hit zero. We can't make a new ref pointer to itself here, as it will re-invoke the destructor when it goes out of scope. This should have been an obvious anti-pattern in hindsight. The object in question can't be in the m_pFontManager, since the font manager retains a reference, and we wouldn't get to this destructor while that is present. So the cleanup isn't required. Fixing this revealed a free-delete mismatch in cxfa_textlayout.cpp. I also converted to use unique_ptrs in a few places near this issue. Fixing this revealed a UAF in CFGAS_GEFont, memcpy'ing a RetainPtr is not a good idea as it doesn't bump the ref count. Also protect and friend the CFGAS_GEFont destructor, to make sure random deletes don't happen. Also kill off a const cast, and remove unnecessary conversion to retain_ptr when we already have one. TEST=look for absence of -11 in XFA corpus test logs, bots not currently noticing the segv. Argh. Review-Url: https://codereview.chromium.org/2631703003
