bitbake: xmlrpc: Show a better error message for connection failures

2013-10-07T08:37:34+00:00

Showing a traceback when unable to connect to a bitbake server is rather ugly. This change allows us to show a sensible error message. (Bitbake rev: 26913202f83fbbecdce95da59515af102bcde4a7) Signed-off-by: Richard Purdie

bitbake: bitbake: cooker,xmlrpc,servers: implement CookerFeatures

2013-09-22T11:19:43+00:00

Implementing feature set selection that allows a client to enable specific features in the server at connection time. Only enabling of features is supported, as there is no way to safely remove data loaded into the cooker. Once enabled, a feature will remain enabled for the life of the cooker. Client-server connection now supports specifying the feature set required by the client. This is implemented in the Process server using a managed proxy list, so the server cooker will now load dynamically needed features based on what client connects to it. In the XMLRPC server the feature set is requested by using a parameter for registerUIHandler function. This allows observer-only clients to also specify features for the server. The server code configuration now is completly separated from the client code. All hardcoding of client knowledge is removed from the server. The extra_caches is removed as the client can now specify the caches it needs using the feature. The UI modules now need to specify the desired featureSet. HOB is modified to conform to the featureSet specification. The only feature available is CookerFeatures.HOB_EXTRA_CACHES which forces loading the bb.cache_extra:HobRecipeInfo class.

bitbake: bitbake: xmlrpc: delete unused code BitBakeUIEventServer

2013-09-13T16:45:22+00:00

BitBakeUIEventServer is an unused class that pushes UI events over a separate thread. The current version of XMLRPC server works just fine with the classic UI event handlers, so this class is not needed.

bitbake: server/xmlrpc: stop server on client exit

2013-09-01T14:51:11+00:00

If the server only expects a single client to connect (i.e. no bind parameter set, so there is no way for the clients to get the server port), stop the server after the first client exits.

bitbake: server/process, server/xmlrpc, runqueue: Use select.select() on fds, not time.sleep()

2013-09-01T14:51:10+00:00

The existing backend server implementations were inefficient since they were sleeping for the full length of the timeouts rather than being woken when there was data ready for them. It was assumed they would wake and perhaps did when we forked processes directory but that is no longer the case. This updates both the process and xmlrpc backends to wait using select(). This does mean we need to pass the file descriptors to wait on from the internals who know which these file descriptors are but this is a logical improvement. Tests of a pathaolgical load on the process server of ~420 rapid tasks executed on a server with BB_NUMBER_THREAD=48 went from a wall clock measurement of the overall command execution time of 75s to a much more reasonable 24s.

bitbake: server/xmlrpc: Increase timeout to 60s

2013-08-30T16:42:39+00:00

This is a better value that the earlier infinite timeout yet still allows for servers with high loads. It does mean the bitbake process can hang at exit for the timeout period but that should never happen and only happened for me in some test cases which wouldn't happen in normal use.

bitbake: bitbake: Add ui event handlers filtering

2013-08-26T10:29:46+00:00

Add functionality to allow UIs to update and change the types of events they recieve. To do this we need to add a new command and also need to be able to obtain the current event hander ID. In the case of xmlrpc, this is straightforward, in the case of the process server we need to save the result in a multiprocessing.Value() so we can retrive it. An excplit command was added to the server API to facilitate this. The same function can also be used to mask or unmask specific log messages, allowing the UI to optionally differ from the standard set of message filtering.

bitbake: server/xmlrpc/prserv: Add sane timeout to default xmlrpc server

2013-08-26T10:29:46+00:00

The standard python socket connect has long timouts which make sense for remote connections but not local things like the PR Service. This adds a timeout parameter to the common xmlrpc server creation function and sets it to a more reasonable 5 seconds. Making the PR server instantly exit is a good way to test the effect of this on bitbake. We can remove the bodged timeout in the PRServer terminate function which has the side effect of affecting global scope.

bitbake: knotty, xmlrpc: add observer-only mode

2013-06-17T15:09:10+00:00

I add an observer only mode for the knotty UI and the XMLRPC server that will allow the UI to register a callback with a server in order to receive events. The observer-UI is able to send read-only commands to the server, and also is able to register as an event handler. Read-only commands are the commands that do not change the state of the server and have been marked as such in the command module. The observer can switch to a full client if it calls addClient at any time, and the server has no other client running.

bitbake: compat/server/utils: Jettison pre python 2.7.3 workarounds

2013-06-14T16:26:30+00:00

Now we've moved to require python 2.7.3, we can jettison the compatibility workarounds/hacks for older python versions. (Bitbake rev: a51c402304f2080a76720f9b31d6dfdbed393bba) Signed-off-by: Richard Purdie
