* bitbake: bitbake-worker: add header with length of messageEtienne Cordonnier2023-11-061-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | The IPC mechanism between runqueue.py and bitbake-worker is currently not scalable: The data is sent with the format <tag>pickled-data</tag>, and bitbake-worker has no information about the size of the message. Therefore, the bitbake-worker is calling select() and read() in a loop, and then calling "self.queue.find(b"</" + item + b">")" for each chunk received. This does not scale, because queue.find has a linear complexity relative to the size of the queue, and workerdata messages get very big e.g. for builds which reference a lot of files in SRC_URI. The number of chunks varies, but on my test system a lot of chunks of 65536 bytes are sent, and each iteration takes 0.1 seconds, making the transfer of the "workerdata" data very slow (on my test setup 35 seconds before this fix, and 1.5 seconds after this fix). This commit adds a 4 bytes header after <tag>, so that bitbake-worker knows how many bytes need to be received, and does not need to constantly search the whole queue for </tag>.

* bitbake: bitbake-worker/runqueue: Avoid unnecessary bytes object copiesEtienne Cordonnier2023-09-221-7/+7
| | | | | | | | | | | | | | | | | | declaring queue=b"" creates an object of types bytes(). bytes() is an immutable object, and therefore doing "self.queue = self.queue + r" creates a new object containing "self.queue" concatenated with "r". On my test setup, we are passing 180MB of data of "workerdata" to the bitbake-worker, so those copies significantly slow down the initialization of the bitbake-worker. Rather use bytearray() which a mutable type, and use extend() to avoid copies. In my test setup, byterray.extend() is 10.000 times faster than copying the queue, for a queue size of 180MB.

* bitbake: cooker: Add FILE_LAYERNAME variable containing the layername for a ↵Richard Purdie2023-05-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | recipe There are times when it would be useful for code to know which layer (or collection in old bitbake terms) it is contained within. Add support for FILE_LAYERNAME to be set by bitbake when parsing a recipe so that it is possible to determine this. To do it, we need to pass data from the cooker into the recipe endpoints, since only the top level cooker information knows about the layer structure which makes the patch a bit painful. The idea is that this would make layer overrides possible: OVERRIDES .= ":layer-${FILE_LAYERNAME}" which then opens possibilities like: WARN_QA:append:layer-core = " patch-fuzz" as an example where OE-Core could enable specific QA tests only for that specific layer.

* bitbake: data: Evaluate the value of export/unexport/network flagsRichard Purdie2023-02-171-1/+1
| | | | | | | | | | | | | | | | | | | Currently the export/unexport/network flags are acted on only by presence or lack of in the data store. This is deliberate due to performance reasons since a given recipe shell task might export ~80-90 variables and this means expanding flags for every one of them. This does catch users unaware since values which expand to nothing don't work e.g. ${@""} and setting values to "0" wouldn't work either. The downside to this patch is slow down in parsing speed of around 4%. The network flag is easier to change and doesn't affect performance, it was made to operate the same as export/unexport for consitency reasons.

* bitbake: lib/bb: Update thread/process locks to use a timeoutRichard Purdie2023-01-051-5/+4
| | | | | | | | | | | | | | | | | | | | | The thread/process locks we use translate to futexes in Linux. If a process dies holding the lock, anything else trying to take the lock will hang indefinitely. An example would be the OOM killer taking out a parser process. To avoid bitbake processes just hanging indefinitely, add a timeout to our lock calls using a context manager. If we can't obtain the lock after waiting 5 minutes, hard exit out using os._exit(1). Use _exit() to avoid locking in any other places trying to write error messages to event handler queues (which also need locks). Whilst a bit harsh, this should mean we stop having lots of long running processes in cases where things are never going to work out and also avoids hanging builds on the autobuilder.

* bitbake: siggen: Add dummy dataCaches from task context/datastoreRichard Purdie2022-12-171-0/+1
| | | | | | | | | | | | | | | One of the challenges in maintaining the code is that it sometimes uses a datacaches structure and sometimes a datastore. Rather than continue the current dual API madness, have the worker contexts create a dummy datacaches structure with the entries we need. Whilst this does need to be kept in sync with the real structure, that doesn't change and this allows the code to be simplified. With this new approach, we can unify the stamps dependency code again.

* bitbake: worker/runqueue: Reduce initial data transfer in workerdataRichard Purdie2022-11-201-10/+22
| | | | | | | | | | | | | | | | | When setting up the worker we were transfering large amounts of data which aren't needed until task execution time. Defer the fakeroot and taskdeps data until they're needed for a specific task. This will duplicate some information when executing different tasks for a given recipe but as is is spread over the build run, it shouldn't be an issue overall. Also take the opportunity to clean up the silly length argument lists that were being passed around at the expense of extra dictionary keys.

* bitbake: BBHandler/cooker: Implement recipe and global classesRichard Purdie2022-08-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | We have some confusion for users since some classes are meant to work in the configuration space (or "globally") and some are meant to be selected by recipes individually. The cleanest way I could find to clarify this is to create "classes-global" and "classes-recipe" directories which contain the approproate classes and have bitbake switch scope between them at the appropriate point during parsing. The existing "classes" directory is always searched as a fallback. Once a class is moved to a specific directory, it will no longer be found in the incorrect context. A good example from OE is that INHERIT += "testimage" will no longer work but IMAGE_CLASSES += "testimage" will, which makes the global scope cleaner by only including it where it is useful and intended to be used (images).

* bitbake: fetch2/cooker: Fix source revision handling with floating upstreamsRichard Purdie2022-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Where a git url uses a tag instead of a full source revision, breakage can currently occur in builds. Issues include: * the revision being looked up in multiple tasks (fetch and unpack) * the risk a different revision may be obtained in those tasks * that some tasks may not be allowed to access the network * that a revision may not be consistent throughout a given build * rerunning a specific task may given inconsistent results To fix this, stop the workers from cleaning out the source revision store. This should only be done in the cooker itself (based on current policy). Also, where the code "sees" an upstream access, mark the recipe as not to be cached. The reparse re-triggers the upstream lookup by the server. Add a test to ensure that if get_srcrev isn't called, the user is told they're using a configuration that is known to break.

Add a "network" task specific flag which then triggers networking to be enabled for this task, it is otherwise disabled. This needs to happen before we enter the fakeroot environment of the task due to the need for the real uid/gid which we save in the parent process.

* bitbake: bitbake: Rework hash equivalenceJoshua Watt2019-09-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: runqueue: Enable dynamic task adjustment to hash equivalencyRichard Purdie2019-08-061-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: runqueue: dry-run real tasks when BB_SETSCENE_ENFORCE is setPaul Eggleton2016-12-201-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | For the purposes BB_SETSCENE_ENFORCE is designed for (in OE, it is used by the installation process for the extensible SDK), we don't actually need the whitelisted real tasks to execute - we just need to have them in the dependency tree so that we get all of the setscene tasks they depend on to run. Therefore we can actually dry-run those real tasks i.e. they won't be run (and thus we won't waste a significant amount of time doing so) and won't be stamped as having run either. We do already have a dry-run mode in BitBake (activated by the -n or --dry-run command line option), but it dry-runs the setscene tasks as well which we don't want here. Note that this has no effect on the checking we are doing with BB_SETSCENE_ENFORCE to ensure that only whitelisted real tasks are scheduled to run - that's handled separately. Fixes [YOCTO #10369].

* bitbake: bitbake-worker: Handle cooker/worker IO deadlockingRichard Purdie2016-11-291-16/+36
| | | | | | | | | | | | | | | | | | | | | | | | I noiced builds where tasks seemed to be taking a surprisingly long time. When I looked at the output of top/pstree, these tasks were no longer running despite being listed in knotty. Some were in D/Z state waiting for their exit code to be collected, others were simply not present at all. strace showed communication problems between the worker and cooker, each was trying to write to the other and nearly deadlocking. Eventually, timeouts would allow them to echange 64kb of data but this was only happening every few seconds. Whilst this particularly affected builds on machines with large numbers of cores (and hence highly parallal task execution) and in cases where I had a lot of debug enabled, this situation is clearly bad in general. This patch introduces a thread to the worker which is used to write data back to cooker. This means that the deadlock can't occur and data flows much more freely and effectively.

* bitbake: bitbake: Initial multi-config supportRichard Purdie2016-08-181-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the notion of supporting multiple configurations within a single build. To enable it, set a line in local.conf like: BBMULTICONFIG = "configA configB configC" This would tell bitbake that before it parses the base configuration, it should load conf/configA.conf and so on for each different configuration. These would contain lines like: MACHINE = "A" or other variables which can be set which can be built in the same build directory (or change TMPDIR not to conflict). One downside I've already discovered is that if we want to inherit this file right at the start of parsing, the only place you can put the configurations is in "cwd", since BBPATH isn't constructed until the layers are parsed and therefore using it as a preconf file isn't possible unless its located there. Execution of these targets takes the form "bitbake multiconfig:configA:core-image-minimal core-image-sato" so similar to our virtclass approach for native/nativesdk/multilib using BBCLASSEXTEND. Implementation wise, the implication is that instead of tasks being uniquely referenced with "recipename/fn:task" it now needs to be "configuration:recipename:task". We already started using "virtual" filenames for recipes when we implemented BBCLASSEXTEND and this patch adds a new prefix to these, "multiconfig:<configname>:" and hence avoid changes to a large part of the codebase thanks to this. databuilder has an internal array of data stores and uses the right one depending on the supplied virtual filename. That trick allows us to use the existing parsing code including the multithreading mostly unchanged as well as most of the cache code. For recipecache, we end up with a dict of these accessed by multiconfig (mc). taskdata and runqueue can only cope with one recipecache so for taskdata, we pass in each recipecache and have it compute the result and end up with an array of taskdatas. We can only have one runqueue so there extensive changes there. This initial implementation has some drawbacks: a) There are no inter-multi-configuration dependencies as yet b) There are no sstate optimisations. This means if the build uses the same object twice in say two different TMPDIRs, it will either load from an existing sstate cache at the start or build it twice. We can then in due course look at ways in which it would only build it once and then reuse it. This will likely need significant changes to the way sstate currently works to make that possible.

* bitbake: bitbake-worker: don't reassign sys.stdoutEd Bartosh2016-07-081-2/+1
| | | | | | | | | | | | | | | | | | | | | | Worker needs input stream in binary mode as it reads binary content from it. Current code does it by detaching a buffer from sys.stdin and assigning it back to sys.stdin. Detached buffer is io.BufferedReader in binary mode. This operation is implicit as its purpose is not easily understandable from the code. Replacing it with fdopen(sys.stdin.fileno(), 'rb') should make the code more understandable. Assigning the buffer to sys.stdin is not needed as worker doesn't use sys.stdin. Moreover, it leads to difficult to debug issues down the stack. For example, devpyshell doesn't work without reopening sys.stdin in text mode. This is not needed anymore after this fix as sys.stdin is not changed in worker code and remains in text mode.
