* | common/ceph_common: add heartbeat perf counters unconditionallySage Weil2018-10-291-18/+23
|/ | | | | | | | | | | | | rgw and rbd_mirror were enabling a perfcounter monitoring the heartbeatmap. Enable this unconditionally for all ccts. This is simpler and more useful! Add a CINIT_FLAG to avoid starting them up. This is only used by the unit tests which do not expect all the cct crap and we don't want to break every time we add a new cct counter. That means removing the CephContextPerfCounters test. Signed-off-by: Sage Weil <sage@redhat.com>

* common: move ConfigValues out of md_config_tKefu Chai2018-07-101-8/+6
| | | | | | | | | | | | by moving ConfigValues out of md_config_t, we are able to point md_config_t to a new ConfigValues instance at runtime, without destroying the old one. also remove ConfigReader, because all md_config_obs_t will be updated with ConfigProxy now. as md_config_t is not able to offer the *data* anymore. Signed-off-by: Kefu Chai <kchai@redhat.com>
* common,rbd,rgw,osd: extract config values into ConfigValuesKefu Chai2018-07-101-31/+31
| | | | | | | | | | | | | | | | | | | | | | | | | this change introduce three classes: ConfigValues, ConfigProxy and ConfigReader. in seastar port of OSD, each CPU shard will hold its own reference of configuration, and upon changes of settings, each shard will be updated with the new setting in async. so this forces us to be able to keep two set of configuration at the same time. so we need to extract the changeable part of md_config_t out. so we can replace the old one with new one on demand, and let different shards share the same unchanged part, amon the other things, the Options map and the lookup tables. that's why we need ConfigValues. we will add a policy template for this class, so we can specialize for Seastar implementation to allow different ConfigProxy instances to point md_config_impl<> to different ConfigValues. because the observer interface is still using md_config_t, to minimise the impact of this change, handle_conf_change() and handle_subsys_change() are not changed. but as it accepts a `const md_config_t`, which cannot be used to create/reference the ConfigProxy holding it, we need to introduce ConfigReader for reading the updated setting from md_config_t in a simpler way, without exposing the internal "values" member variable.

* common: add LockPolicy to md_config_tKefu Chai2018-06-271-0/+2
| | | | | | | | | before this change, we guard all read/write access to md_config_t with a lock. after this change, this policy is optional. and is controled by a enum named `LockPolicy`. we will use `md_config_impl<LockPolicy::SINGLE>` to implement the lockless config used by crimson/osd.

* common/config: rewrite (╯°□°)╯︵ ┻━┻Sage Weil2018-03-061-56/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is too complete a rewrite to reasonably break down into small steps, and even if I could, it would be harder to review that way than to simply review the new implementation. The semantics of the old one were so weird that it's harder to reason about the change in behavior than to simply review the new behavior. That's my story, at least, and I'm sticking to it! So, here are the highlights: - $foo meta expansions are evaluated at get_val() time. This means the weird bool arguments to set_val specifying whether things were expanded are removed (they didn't make any sense unless you were thinking about the old implementation). - for every option, we track values from any inputs (config, mon, override). At get_val() time, we pick the highest priority one. - diff() is rewritten to be simple and to show you all of the above. - internal interfaces are simplified, and in terms of Option::value_t whenever possible. - unit tests simplified somewhat based on the above. Known issues: - legacy values get pushed out in select cases. Notably if foo=$bar and bar is updated, we do not update $foo (there is no dependency tracking to do this efficiently).

* | common/admin_socket: Copy fewer stringsAdam C. Emerson2018-02-161-10/+10
|/ | | | | | | | | | | | | | | | Pass std::string_view to call, rather than passing strings by value. Change cmdmap_t and the maps in admin_socket to use the std::less<> transparent comparator, so we can compare string_views to strings. (Or anything else with an equality operator with strings.) Pass the cmdmap_t in to call by const reference, not reference. The change to cmdmap_t requires changing some of the users of cmdmap_t. (That is, make them actually use cmdmap_t explicitly, not the open-coed map type.) Signed-off-by: Adam C. Emerson <aemerson@redhat.com>
