Cpu consume 100% when \copy

Open peresun opened this issue 4 years ago • 4 comments

When I run '\copy ... from ...', odyssey consume 100% CPU. Writev will always retry forever even if no buffer left when NON_BLOCK is set. But I think close NON_BLOCK is not a good idea.

Another question: Does Odyssey correctly handle the problem of successful writing of partial data of writev?

I think mm_iov_advance handle the problem, thanks

Thanks for reaching out. Sorry, i did not have time yet to reproduce the problem. Did you find out that COPY works OK?

Copy works OK, but cpu consume 100%.

This seems like a bug which we would have to address. Though I still did not reproduce it :(
