* mds: be more careful about decoding LogEventswip-4221Greg Farnum2013-09-111-4/+10
| | | | | | | We need to wrap the full decode section or we can abort the process if there's an issue (which we may want to just skip by). Signed-off-by: Greg Farnum <greg@inktank.com>

| | | | | | | | | | | | | | | | Right now these are very basic and aren't as sophisticated as we want them to end up, but we have a skeleton for where to put the decision-making logic. Signed-off-by: Greg Farnum <greg@inktank.com>
| * Objecter: follow redirect replies from the OSDGreg Farnum2013-09-101-8/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | If we get back a redirect reply, we clean up the Op's external references and re-send using the target_oloc and target_oid. To facilitate this, recalc_op_target() now only fills them in and overrides them with pool cache semantics if they're empty. Keep in mind that this is a pretty simple redirect formula -- the Objecter will keep following redirects forever if that's what the OSDs send back. The client is not providing any synchronization right now. Signed-off-by: Greg Farnum <greg@inktank.com>
| * Objecter: write a helper function to clean up ops that need to be retriedGreg Farnum2013-09-102-4/+11
| | | | | | | | | | | | | | | | We have a little block to clean them up if we get back EAGAIN, but it's actually leaking map references; we will also use this for redirects from the OSDs. Signed-off-by: Greg Farnum <greg@inktank.com>
| * MOSDOpReply: add a redirect memberGreg Farnum2013-09-101-1/+13
| | | | | | | | | | | | | | | | | | | | | | When present, clients must send the request to the location specified by the redirect (by using the combine_with_locator() function on request_redirect_t). A separate mechanism must be used to ensure that clients see and respect the redirect, as we do not bump up the minimum required version to decode. Signed-off-by: Greg Farnum <greg@inktank.com>

| | | | | | | | | | | | | | For now it's just a copy of base_oid, but soon we will allow it to be overwritten for OSD-driven redirects. Signed-off-by: Greg Farnum <greg@inktank.com>
| * Objecter: rename Op::oid -> Op::base_oidGreg Farnum2013-09-102-8/+8
| | | | | | | | | | | | | | | | | | Analagous to the oloc->base_oloc rename we did in e2fcad09d94d965867147627b73e99da9454436f, we may specify a different target name for a redirect. Rename the existing oid to base_oid to avoid any confusion. Signed-off-by: Greg Farnum <greg@inktank.com>

| * ReplicatedPG: do not meaninglessly fill in the reqid on make_writeable() cloningGreg Farnum2013-09-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reqid is used to fill in a map that is used for giving clients the correct version on replayed ops, unless the reqid is blank (in which case it doesn't go into the map). Indirect clones are not ops that the client wants to observe and the version is incorrect right now, so don't fill it in. Note that this should not have actually caused any buggy behavior, because the map would have simply been overwritten by the real requested event a short time later (while still protected by locks and things). But it's very confusing. Signed-off-by: Greg Farnum <greg@inktank.com>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the introduction of the erasure code pool, arguments to be interpreted depending on the pool type must be introduced. For instance the erasure code pool loads a plugin at run time will use easure-code-k=10 to split each object in 10. The arguments are described as name=properties,type=CephString,n=N,req=false,goodchars=[A-Za-z0-9-_.=] If key=value it is stored in the new properties data member of pg_pool_t as properties[key] = value, otherwise the value is the empty string. The pg_pool_t version is bumped to 10 and the encode/decode methods modified to take the properties into account. The generate_test_instances method creates a two entries map, one of which is the empty string to cover the case when no value is specified. http://tracker.ceph.com/issues/6113 refs #6113 Signed-off-by: Loic Dachary <loic@dachary.org>

The registry has a single entry point ( method factory ) and should be used as follows: map<std::string,std::string> parameters; parameters["directory"] = "/usr/lib/ceph/erasure-code"; ErasureCodeInterfaceRef erasure_code; ErasureCodePluginRegistry &instance = ErasureCodePluginRegistry::instance(); instance.factory("jerasure", parameters, &erasure_code)); If the plugin requested ( "jerasure" in the example above ) is not found in the *plugins* data member, the load method is called and will: * dlopen(parameters["erasure-code-directory"] + "jerasure") * f = dlsym("__erasure_code_init") * f("jerasure") * check that it registered "jerasure" The plugin is expected to do something like instance.add(plugin_name, new ErasureCodePluginJerasure()); to register itself. The factory method is protected with a Mutex to avoid race conditions when using the same plugin from two threads.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An erasure code implementation designed for tests. Although it is fully functional and could be used on actual data, it is mainly provided for testing purposes. It splits data in two, computes an XOR parity and can sustain the loss of one chunk. The constructor will usleep(3) for parameters["usleep"] microseconds so that the caller can create race conditions. http://tracker.ceph.com/issues/5878 refs #5878 Signed-off-by: Loic Dachary <loic@dachary.org>
