bitbake: build/msg: Cleanup verbose option handling

2020-08-25T17:14:53+00:00

The levels of indirection to set these verbose logging options is rather crazy. This attempts to turn things into two specific options with much more specific meanings. For now its all still controlled by the commandline verbose option and should funciton as previously, with the addition that the BB_VERBOSE_LOGS option can now be task specific.

bitbake: bitbake-worker: Remove unnecessary addDefaultLogFilter

2020-03-13T11:29:23+00:00

Adding the default log filter here is unnecessary because there are no defined logging domains when it is called, which means it does no actual filtering. (Bitbake rev: dcdb8f2c14f09ce34d0a1facc33a441570912c05) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

bitbake: lib/bb/msg: Use log level instead of debug count

2020-03-13T11:29:23+00:00

Passes around the actual logging level as the default log level variable instead of the debug count. This makes it easier to deal with logging levels since the conversion from debug count and verbose flag only has to occur once when logging is initialized and after that actual log levels can be used (Bitbake rev: 41bd155faf7f65cb0727fcce972715769b26ca89) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

bitbake: bitbake-worker child process create group before registering SIGTERM handler

2019-11-07T15:12:29+00:00

The bitbake-worker child on the SIGTERM signal handling send the SIGTERM to all processes in it's process group. In cases when the bitbake-worker child got SIGTERM after registering own SIGTERM handler and before the os.setsid() call it can send SIGTERM to unwanted processes. In the worst case during SIGTERM processing the bitbake-worker child can be in the group of the process that started BitBake itself. As a result it can kill processes that not related to BitBake at all. (Bitbake rev: b97b1ef0b1b00848a4a44b34eca123ccf33188f4) Signed-off-by: Ivan Efimov Signed-off-by: Richard Purdie

bitbake: bitbake: Rework hash equivalence

2019-09-18T16:52:01+00:00

Reworks the hash equivalence server to address performance issues that were encountered with the REST mechanism used previously, particularly during the heavy request load encountered during signature generation. Notable changes are: 1) The server protocol is no longer HTTP based. Instead, it uses a simpler JSON over a streaming protocol link. This protocol has much lower overhead than HTTP since it eliminates the HTTP headers. 2) The hash equivalence server can either bind to a TCP port, or a Unix domain socket. Unix domain sockets are more efficient for local communication, and so are preferred if the user enables hash equivalence only for the local build. The arguments to the 'bitbake-hashserve' command have been updated accordingly. 3) The value to which BB_HASHSERVE should be set to enable a local hash equivalence server is changed to "auto" instead of "localhost:0". The latter didn't make sense when the local server was using a Unix domain socket. 4) Clients are expected to keep a persistent connection to the server instead of creating a new connection each time a request is made for optimal performance. 5) Most of the client logic has been moved to the hashserve module in bitbake. This makes it easier to share the client code. 6) A new bitbake command has been added called 'bitbake-hashclient'. This command can be used to query a hash equivalence server, including fetching the statistics and running a performance stress test. 7) The table indexes in the SQLite database have been updated to optimize hash lookups. This change is backward compatible, as the database will delete the old indexes first if they exist. 8) The server has been reworked to use python async to maximize performance with persistently connected clients. This requires Python 3.5 or later. (Bitbake rev: 2124eec3a5830afe8e07ffb6f2a0df6a417ac973) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

bitbake: cooker/hashserv: Allow autostarting of a local hash server using BB_HASHSERVE

2019-08-06T10:21:31+00:00

Its useful, particularly in the local developer model of usage, for bitbake to start and stop a hash equivalence server on local port, rather than relying on one being started by the user before the build. The new BB_HASHSERVE variable supports this. The database handling is moved internally into the hashserv code so that different threads/processes can be used for the server without errors.

bitbake: runqueue: Enable dynamic task adjustment to hash equivalency

2019-08-06T10:21:31+00:00

There is a compelling usecase for tasks being able to notify runqueue that their "unihash" has changed. When this is recieved, the hashes of all subsequent tasks should be recomputed and their new hashes checked against existing setscene validity. Any newly available setscene tasks should then be executed. Making this work effectively needs several pieces. An event is added which the cooker listen for. If a new hash becomes available it can send an event to notify of this. When such an event is seen, hash recomputations are made. A setscene task can't be run until all the tasks it "covers" are stopped. The notion of "holdoff" tasks is therefore added, these are removed from the buildable list with the assumption that some setscene task will run and cover them. The workers need to be notified when taskhashes change to update their own internal siggen data stores. A new worker command is added to do this which will affect all newly spawned worker processes from that worker. An example workflow which tests this code is: Configuration: BB_SIGNATURE_HANDLER = "OEEquivHash" SSTATE_HASHEQUIV_SERVER = "http://localhost:8686" $ bitbake-hashserv & $ bitbake automake-native $ bitbake autoconf-native automake-native -c clean $ bitbake m4-native -c install -f $ bitbake automake-native with the test being whether automake-native is installed from sstate.

bitbake: bitbake: Add initial pass of SPDX license headers to source code

2019-05-04T09:44:04+00:00

This adds the SPDX-License-Identifier license headers to the majority of our source files to make it clearer exactly which license files are under. The bulk of the files are under GPL v2.0 with one found to be under V2.0 or later, some under MIT and some have dual license. There are some files which are potentially harder to classify where we've imported upstream code and those can be handled specifically in later commits. The COPYING file is replaced with LICENSE.X files which contain the full license texts. (Bitbake rev: ff237c33337f4da2ca06c3a2c49699bc26608a6b) Signed-off-by: Richard Purdie

bitbake: runqueue: Pass unique hash to task

bitbake: bitbake-worker: Pass taskhash as runtask parameter

2018-12-07T12:38:58+00:00

Pass the task hash as a parameter to the 'runtask' message instead of passing the entire dictionary of hashes when the worker is setup. This is possible less efficient, but prevents the worker taskhashes from being out of sync with the runqueue in the event that the taskhashes in the runqueue change.
