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

2016-09-08Reland of Fix leaked internal fontweili
Reland of Fix leaked internal font (patchset #2 id:60001 of https://codereview.chromium.org/2297303004/ ) In CFGAS_FontMgrImp::LoadFont(), a new internal font is created which is never released. It needs to be correctly marked as internal font to be released. Fix this by adding a new method to take the ownership of the font and mark it as internal font properly.

2016-08-23[XFA] Force destruction order of font managers.chromium/2838dsinclair
The GEFont points to the font manager which creates it and tries to unregister itself. Currently the GEFont can be created by the default mapper and then stored in a different mapper. If the default mapper is destroyed first, when the second mapper cleans up the font there will be a call to unregister on the default mapper causing a use-after-free. The long term fix is to fixup the GEFont so it points to the correct mapper to unregister from. This CL forces the destruction order in CXFA_FFApp to cleanup the non-default mapper first.
