Hi kefu, Even we use seastar::thread, I think we still need #ifdef macro to build these code together, am I right? The same binary still contain both blocking code and unblocking code. Let's discuss it in the meeting. -Chunmei > -----Original Message----- > From: kefu chai [mailto:tchaikov@xxxxxxxxx] > Sent: Monday, July 22, 2019 7:37 AM > To: Liu, Chunmei <chunmei.liu@xxxxxxxxx>; dev@xxxxxxx > Subject: [crimson] bluestore in an alien world > > hi Chunmei, > > i am reviewing your change of > https://github.com/ceph/ceph/compare/master...liu- > chunmei:ceph_seastar_alien_store. > it looks good in general. i think the simplest way to co-locate different versions > of alien-common, ceph-common and crimson-common is to introduce different > namespaces. because we need to have alien-common and crimson-common in > the same binary, and to have all of these three versions in the same repository. > > but this divergence concerns me, as it introduces yet another condition in the > shared infrastructure in our code base. and in the long run, this #ifdef won't go > away if we want to go this way, so i need to at least give it a try. what is "it"? to > port rocksdb to seastar. as seastar offers "seastar::thread" which makes it > relative simpler to wrap the blocking calls with ucontext. and rocksdb offers a > abstraction machinery allowing one to port it to a new platform. and seastar is a > "platform" to some degree, i'd say. > > will update you guys with my progress and findings. > > > -- > Regards > Kefu Chai _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
