@xpader It'd be great to get a binary dump of the received / sent bytes to find the bug in our HPackNative implementation. Note that sharing these headers could contain sensitive values.

Which OS / distro do you use that has these paths?

from hpack.

@kelunik OS is Ubuntu 20.04.5 LTS x64, and how to get a binary dump with received / sent bytes?

from hpack.

After change to HPackNgHttp2, some error appeared: Cannot instantiate FFI\CData of zero size.
Tough..

from hpack.

@xpader don't worry about the binary dump, I did some fuzzing yesterday and discovered several strange cases I need to investigate further.

from hpack.

I fixed the Cannot instantiate FFI\CData of zero size issue in the current branch. I'll tag a bugfix release for that change while we find some time to investigate the other issue.

I have a http request example to reproducer this error (still exists in version 3.1.3), but the example include some sensitive infomation, how could I send this to you?

from hpack.

FFI memory leak very exaggerated, and memory is leak outer of PHP memory manager.
The memory info from memory_get_usage() is very normal, but in system, php process memory is now 4G after running 2 days. Even set memory_limit for php, process still not exit after memory exceed.

Mail has been sent to you, any updates?

from hpack.

@xpader Do you use the proxy-authenticate header?

from hpack.

@kelunik No.
Did you received the mail? I have sent the simple request example can reproduce this issue.

from hpack.

@xpader Yes, I received it, I should have had another look at it before writing that comment. Anyway, I could reproduce the issue and have fixed it now. Thanks for reporting!
