Sort answer: no. Re issue 28: I will look into this more today. I was able to generate a segfault on connection shutdown on Friday and work on a fix.
Longer version re buckets: - even though buckets for a request are created inside a single worker thread, they are mutated/split/placed on free list upon processing down the main connection. Which then all affects their bucket_alloc_t from several threads. Especially on longer response bodies, - since there are no function pointers for bucket_alloc_t, it is not obvious to me how one would replace them with another implementation. - what can be added are, of course, new bucket implementations. Maybe there is an approach to move the data itself without copying more than once. With a clever handling of file buckets, maybe no copying at all. Otherwise, I am open to ideas. //Stefan > Am 21.06.2015 um 17:07 schrieb Eric Covener <cove...@gmail.com>: > > re: https://github.com/icing/mod_h2/issues/28 has this design further evolved? > > Is there a way to make the deep copy un-necessary by injecting your > own bucket_alloc created with a pool with a threadsafe allocator very > early?
