* bitbake: hashserv: let asyncio discover the running loopJustin Bronder2021-11-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | >From 3.10 documentation [1]: Deprecated since version 3.8, removed in version 3.10: The loop parameter. This function has been implicitly getting the current running loop since 3.7 This is fixed in master as a side-effect of cf9bc0310b0092bf52b61057405aeb51c86ba137 which is more intrusive but likewise drops the loop parameter. 1. https://docs.python.org/3/library/asyncio-stream.html#asyncio.open_connection (Bitbake rev: 573968cb3e04567559d400a753f0be8d5a0da0b8) Signed-off-by: Justin Bronder <jsbronder@cold-front.org> Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> (cherry picked from commit 74a1e71b1e677a482fdedc685a71a1798ad63920) Signed-off-by: Anuj Mittal <anuj.mittal@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* bitbake: hashserv: Add get-outhash messagePaul Barker2021-02-101-14/+32
| | | | | | | | | | | | | | | The get-outhash message can be sent via the get_outhash client method. This works in a similar way to the get message but looks up a db entry by outhash rather than by taskhash. It is intended to be used as a read-only form of the report message. As both handle_get_outhash and handle_report use the same query string we can factor this out.

* bitbake: hashserv: server: Support searching upstream for outhashPaul Barker2021-02-101-0/+20
| | | | | | | | | | | | | Use the new get-outhash message to perform a read-only query against an upstream server (if present) when a reported taskhash/outhash combination is not found in the current database. If a matching entry is found upstream it is copied into the current database so it can be found by future queries.

* bitbake: hashserv: Support read-only serverPaul Barker2021-02-101-7/+18
| | | | | | | | | | | | | | | | | | The -r/--readonly argument is added to the bitbake-hashserv app. If this argument is given then clients may only perform read operations against the server. The read-only mode is implemented by simply not installing handlers for write operations, this keeps the permission model simple and reduces the risk of accidentally allowing write operations. As a sqlite database can be safely opened by multiple processes in parallel, it's possible to start two hashserv instances against a single database if you wish to export both a read-only port and a read-write port.

* bitbake: bitbake: hashserve: Add support for readonly upstreamJoshua Watt2020-11-241-30/+119
| | | | | | | | | | | | | | | | Adds support for an upstream server to be specified. The upstream server will be queried for equivalent hashes whenever a miss is found in the local server. If the server returns a match, it is merged into the local database. In order to keep the get stream queries as fast as possible since they are the critical path when bitbake is preparing the run queue, missing tasks provided by the server are not immediately pulled from the upstream server, but instead are put into a queue to be backfilled by a worker task later.

* bitbake: hashserv: Chunkify large messagesJoshua Watt2020-06-281-33/+72
| | | | | | | | | | | | | | | | The hash equivalence client and server can occasionally send messages that are too large for the server to fit in the receive buffer (64 KB). To prevent this, support is added to the protocol to "chunkify" the stream and break it up into manageable pieces that the server can each side can back together. Ideally, this would be negotiated by the client and server, but it's currently hard coded to 32 KB to prevent the round-trip delay.

* bitbake: hashserv: Add support for equivalent hash reportingRichard Purdie2019-12-041-0/+36
| | | | | | | | | | | | | | | | | | | | | | | The reason for this should be recorded in the commit logs. Imagine you have a target recipe (e.g. meta-extsdk-toolchain) which depends on gdb-cross. sstate in OE-Core allows gdb-cross to have the same hash regardless of whether its built on x86 or arm. The outhash will be different. We need hashequiv to be able to adapt to the prescence of sstate artefacts for meta-extsdk-toolchain and allow the hashes to re-intersect, rather than trying to force a rebuild of meta-extsdk-toolchain. By this point in the build, it would have already been installed from sstate so the build needs to adapt. Equivalent hashes should be reported to the server as a taskhash that needs to map to an specific unihash. This patch adds API to the hashserv client/server to allow this.

* bitbake: bitbake: Rework hash equivalenceJoshua Watt2019-09-181-0/+414
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.
