2018-06-01GCC6: workaround bug with external class template linking.José Dapena Paz
In the case of ByteStringView and WideStringView, non official build fails to link in GCC 6.3 or older. But it works in GCC 7.2. A workaround for this problem is avoiding declaring in same file extern and explicit class template for them. It seems to be related to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57728 though that bug is supposed to be already fixed in 6.3.0.

2018-05-25Make CPDF_Page retainable.Tom Sepez
Small step to reducing the differences between XFA and non-XFA. We still use the RetainPtr pretty much as if it were an unique_ptr, in that we're not yet caching pages and handing out multiple pointers to the same page in the non-XFA case. The one change is in page view cleanup, where we no longer need a boolean and can take (sufficient) page ownership with a RetainPtr. Tidy up some document.h -> page.h -> document.h circular inclusion while we're at it. NOTE: Wait for imminent branch to pass before landing. We'll want this to bake a while.

2018-05-17Expose CJBig2_Image::ComposeTo() as a public method.Lei Zhang
CJBig2_Image::ComposeFrom() wraps a call to ComposeTo() and does an extra validity check. In tight loops where the validity check will always succeed, this is wasteful. Change existing callers of ComposeFrom() to ComposeTo() when the validity check has already been done.
