Author: Lei Zhang <thestig@chromium.org>

Make memory usage in CJBig2_HTRDProc::DecodeImage() O(1).

Instead of allocating an N-pixel array to store some temporary values,
just use a single integer.

ClusterFuzz testcase 4971629319553024 is still reproducing on tip-of-tree build (trunk).

Please re-test your fix against this testcase and if the fix was incorrect or incomplete, please re-open the bug. Otherwise, ignore this notification and add ClusterFuzz-Wrong label.

CF has gone from OOM in CJBig2_HTRDProc::DecodeImage() to timing out further inside CJBig2_HTRDProc::DecodeImage().

The test case runs in ~9 seconds locally, but on the bot it times out after 25.

commit 3689975377feb92a84488cd51b1cb30c818e3d55
Author: Lei Zhang <thestig@chromium.org>
Date: Thu May 17 17:21:22 2018

Expose CJBig2_Image::ComposeTo() as a public method.

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.

Oh, CF is running ASAN + debug build. This is going to be super slow. (135 seconds locally)

mmoroz: Any advice on how to proceed here? I can keep trying to optimize the code, but I'm not sure I'll ever get it down to under 25 seconds.

I think it's fine to WontFix performance related issues reported with ASan + Debug build.

Closing as Fixed since the original OOM has been fixed, and CF then noticed the same test case is too slow.
