* nstore: rename public xenstore headersIan Campbell2012-05-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | The xenstore header xs.h is producing conflicts with other software[1]. xs is a too short identifier and does not matche the library. Renaming the headers to xenstore.h and xenstore_lib.h is the easiest way to make them easy recognizable and prevent furthe problems.

* xenstored now supports multiple concurrent transactions perkaf24@firebug.cl.cam.ac.uk2005-10-101-14/+45
| | | | | | | | | | | | | | | | | | | | connection, plus interleaving of transactional and non-transactional accesses. A transaction identifier is added to the xsd_sockmsg header structure (0 means 'not in context of a transaction'). The user and kernel xs interfaces accept a pointer to a transaction handle where appropriate -- currently this is directly cast to an integer identifier in the client library / kernel driver, but will allow for keeping extra dynamic client-side state in future if we need to. The transaction mutex has now gone. It's replaced with a read-write mutex, but this is only acquired for exclusive access during suspend/resume, to ensure there are no in-progress transactions.

* Make xenstored use tdb, transactions can soft-fail (EAGAIN)Rusty Russell2005-09-231-206/+46
| | | | | | | | | | | | | | Transactions no longer take root dir, no longer lock & block: commit can fail spuriously with EAGAIN, not ETIMEDOUT. Speeds up transactions by over 1000 times, should be NFS safe. New program: xs_tdb_dump to dump raw TDB contents. Don't do failure testing: we are no longer robust against all ENOMEM 8( Introduce "struct node" which contains perms, children and data. Make struct xs_permissions unpadded, so we can write to tdb w/o valgrind complaints. Gently modify TDB to use talloc, not do alloc on tdb_delete. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| | | | | | | | | | | | | connection which did write/mkdir/rm/setperm etc. This causes deadlocks in real life, and I can't see a sane way of avoiding them: it is reasonable for someone to ignore watch notifications while doing other actions, and that means that we can do other writes. These writes can block pending other watchers; if one of these is the process blocked awaiting our ack, we deadlock.
