logging - How is poxos keep replication logs in sync practically -

-

i read paxos can used keep replications in sync syncing operation logs replications.

to understanding each paxos instance define log id operation

ideally log on each nodes, therefore apply operation log in order of log id keep data consistent each other

  1. delete ....
  2. add ...
  3. remove ...

to understanding log id not increased 1 one , log should :

1.delete ....

3.add ...

5.remove ...

i guess questions how work practically if 1 node down, during paxos instance?

because node miss 1 log entry, how node knows missed entry after recovered ?

according wiki

https://en.wikipedia.org/wiki/paxos_(computer_science)#multi-paxos

multiple-paxos seems implemented in way of make sure log id increase no gap.

that's said, understanding, each replicate still need periodically talk make sure on latest change.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
