* MonClient: pass function parameter by referenceDanny Al-Gaaf2014-02-191-1/+1
| | | | | | | | | | [src/mon/MonClient.h:412]: (performance) Function parameter 'mon_name' should be passed by reference. Changed also parameter name in function implementation to match name in declaration. Signed-off-by: Danny Al-Gaaf <danny.al-gaaf@bisect.de>

| * monc: backoff the timeout period when reconnectingGreg Farnum2014-02-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | If the monitors are systematically slowing down, we don't want to spam them with reconnect attempts every three seconds. Instead, every time we issue a reconnect, multiply our timeout period by a configurable; when we complete the connection, reduce that multipler by 50%. This should let us respond to monitor load. Of course, we don't want to do that for initial startup in the case of a couple down monitors, so don't apply the backoff until we've successfully connected to a monitor at least once.

| * monc: let users specify a callback when they reopen their monitor sessionGreg Farnum2014-02-131-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | Then the callback is triggered when a new session is established, and the daemon can do whatever it likes. There are no guarantees about how long it might take to trigger, though. In particular we call the provided callback while not holding our own lock in order to avoid deadlock. This could lead to some funny ordering from the user's perspective if they call reopen_session() again before getting the callback, but there's no way around that, so they just have to use it appropriately.

| * msgr: use ConnectionRef throughoutSage Weil2013-06-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Make RefCountedObject a private parent of Connection so that users are forced to use ConnectionRef whenever references are taken. Many methods can still take a raw Connection* when they are using the caller's reference but not taking their own; this is cheaper than twiddling the reference count, and the lifetime is still well defined. Local variables generally use ConnectionRef, though. Signed-off-by: Sage Weil <sage@inktank.com>

* monc: only warn about missing keyring if we fail to authenticateSage Weil2012-12-211-0/+1
| | | | | | | | | This avoids the situation where a librados or other user with the default of 'cephx,none' and no keyring is authenticating against a cluster with required of 'none' and an annoying warning is generated every time.

* monclient: add an initialized bool to guard shutdown.Greg Farnum2011-10-051-0/+1
| | | | | | | | | | | | | The addition of a Finisher in 9c56070bc20878e87fcb4715b0a3559dd1aaf9ff broke shutdown in the case where MonClient::init() was never called, so add a guard variable to keep track. I'm not sure this is actually the best solution (Timer guard itself, for instance; maybe Finisher should too?), but I don't want to change the Finisher interface without looking at it more carefully than I'm going to right now.

| | | | | | | | | | | | | | | | | MonClient should contain a KeyRing and a RotatingKeyRing. All the MonClient users, except possibly csyn, don't want to manage those objects themselves. Don't chdir until after we have opened the KeyRing. If the KeyRing is at a relative path, a chdir may make it inaccessible. Separate the chdir function from the daemonize function. Refactor the cmds argument parsing a little bit. Separate the special actions from the normal operations of the daemon. This should allow librados and libceph to support CephX finally! yay!

* Timer: fix timer shutdown, efficiency issuesColin Patrick McCabe2010-11-041-1/+2
| | | | | | | | | | | | | | | | | Rework Timer and SafeTimer to be more efficient and to handle shutdown correctly. Document the API, especially what locks need to held where. The destructor for both Timer and SafeTimer now joins the timer thread safely. The shutdown() function is available to callers who want to join it before the Timer is destroyed. To make things more efficient, don't create a new std::set every time we insert a Context. Use multimap instead. Don't signal the condition variable unless the event we have insert comes before all the other events in the scheduled map. Don't allocate an extra Context in SafeTimer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, we would provide "have" and a bool "onetime" flag. The struct was also screwed up with an extra __le64. Then have=0 was a special case that meant "give me the latest". The problem is this is ambiguous between the usual "give me everything since X" and "give me your latest", because you might actually have 0 and want 1..current. Changes protocol and cleans up the struct: - now "start" and "flags", where only 1 flag (ONETIME) is defined - clean up sub_want_* methods throughout - fix all sub_want callers to ask for _start_ (not have) epoch, or 0 for any/latest - add a feature bit; talks old clients w/o that bit Signed-off-by: Sage Weil <sage@newdream.net>
