| * Add conditional exception reraiseBen Nemec2013-07-021-11/+27
| | | | | | | | | | | | | | | | | | | | In some cases we need to save an exception and reraise it only under certain conditions. As written, the save_and_reraise_exception context always reraises, which means it can't always be used. This change adds a flag that allows conditional reraising to address the limitation.

| * Improve usability when backdoor_port is nonzeroRaymond Pekowski2013-06-231-3/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users who may not know that configuring a backdoor_port with 0 allows multiple services to be enabled for the eventlet backdoor or who simply want a more predictable port assignment might like this patch. If the specified port is in use, it is incremented until a free port is found. This is a backdoor_port collision recovery scheme as opposed to the collision failure scheme that exists today. This related to I95fdb5ca: Add support for backdoor_port to be returned with a rpc call. Change-Id: I7ec346db3575995fa15483b617eea34c1e003bb0

There are unprotected holes in the thread kicked off by RPC consume_in_thread such that an exception will kill the thread. This exists for both the service (TopicConsumer) and the new reply proxy (DirectConsumer) consumers. This patch plugs those holes as close to the base of the consumer thread as possible by catching all non-caught exceptions and retrying with sleeps between retries and some pacing of the log output to prevent log flooding.

IpNetnsExecFilter has been restricted to ensure that the filter chains have all matching filters run as the same user. EnvFilter is a new filter derived from CommandFilter that allows a Command to be optionally prefixed by "env" and a specific list of environment variables. This is intended to replace the specific DnsmasqFilter and DnsmasqNetnsFilter in the future when all consumers have been updated.

So all places like: except SomeException as e: raise e should be replaced by except SomeException: raise If we are doing some other actions before reraising we should store information about exception then do all actions and then reraise it. This is caused by eventlet bug. It lost information about exception if it switch threads. fixes bug 1191730 Change-Id: I7bce659591c4c3e4bc41e12d7d8390128c30e2e4

The framework basically allows a way for a single plugin to register API extensions and notification hooks. Both of these can be done by directly using config opts like osapi_compute_extension and notification_driver so this framework really only helps if we expected to (and wanted to) lots of these plugins in the wild. Nova is the only project using this and we don't have an active maintainer listed in the MAINTAINERS file, so it seems like it's time to remove it from the incubator.

AggregateNotFound) was raised in the bottom layer, the next layer up would turn it into a special exception ( AggregateNotFound_Remote ), then in the final layer, it would see this as an unrecognizable exception and raise RemoteException. After this patch, at each layer where the expeption is deserialized, it'll recognize exceptions with the _Remote postfix, and leave them as they are, instead of turning them into RemoteExceptions. It also preserves the exception's original __module__ now. Change-Id: I158a80f1cec20d3e1805b565ffddaffd7a15295b
