classes: Update classes to match new bitbake class scope functionality

2022-08-12T14:27:17+00:00

Move classes to classes-global or classes-recipe as appropriate to take advantage of new bitbake functionality to check class scope/usage. (From OE-Core rev: f5c128008365e141082c129417eb72d2751e8045) Signed-off-by: Richard Purdie

classes: Add SPDX license identifiers

2022-08-12T10:58:01+00:00

As stated in our top level license files, the license is MIT unless otherwise stated. Add SPDX identifers accordingly. Replace older license statementa with the standardised syntax. Also drop "All Rights Reserved" expression as it isn't used now, doesn't mean anything and is confusing. (From OE-Core rev: 081a391fe09a21265881e39a2a496e4e10b4f80b) Signed-off-by: Richard Purdie

classes: Add copyright statements to files without one

2022-08-12T10:58:01+00:00

Where there isn't a copyright statement, add one to make it explicit. Also drop editor config lines where they were present. (From OE-Core rev: 880c1ea3edc8edef974e65b2d424fc36809ea034) Signed-off-by: Richard Purdie

buildstats.bbclass: correct sampling of system stats

2022-06-29T15:16:56+00:00

The last time of sampling would be updated within the SystemStats class but not re-recorded into the datastore, leading to multiple samples being collected in the same second in the sample function of buildstats.py. Fix this to collect and store only one sample per second within a certain tolerance to deal with variation in the arrival time. This fix elimates the spikiness of sampled data, in cases where the difference between the current and the last sample is taken. Previously, since many samples per second were recorded, certain types of data would result in a very small elapsed time and hence a small numerical difference. For example, the CPU usage from /proc/stat is a running total of usage and taking the difference between data collected 0.1 seconds apart would result in usage appearing lower than it actually was.

buildstats.bbclass: log host data on failure to task specific file

2021-07-10T21:42:22+00:00

host data, for both interval and failure, was previously logged into the same file which was difficult to read as the files file were usually large. host data is now logged into separate files, for each type of logging (failure and interval) and also for each failed task making it easier to read/parse.

buildstats.bbclass: collect data in the same file.

2021-04-27T22:43:57+00:00

Previously "at interval" and "on failure" logs were collected in separate files. Collect both types of logging in the same file for better analysis. Introduced new variable which allows different set of commands to be run by the different logging, interval or failure. The variables are BB_LOG_HOST_STAT_CMDS_INTERVAL and BB_LOG_HOST_STAT_CMDS_FAILURE respecteviely.

buildstats.bbclass: improve timeout handling

2021-03-11T14:00:36+00:00

The subprocess that runs the commands periodically times out prematurely even when there is sufficient time available within the given interval for the commands to run. This change improves timeout handling and give all the commands equal time to run.

buildstats.bbclass: add functionality to collect build system stats

2021-01-17T11:28:13+00:00

There are a number of timeout and hang defects where it would be useful to collect statistics about what is running on a build host when that condition occurs. This adds functionality to collect build system stats on a regular interval and/or on task failure. Both features are disabled by default. To enable logging on a regular interval, set: BB_HEARTBEAT_EVENT = "" BB_LOG_HOST_STAT_ON_INTERVAL = Logs are stored in ${BUILDSTATS_BASE}//host_stats To enable logging on a task failure, set: BB_LOG_HOST_STAT_ON_FAILURE = "" Logs are stored in ${BUILDSTATS_BASE}//build_stats The list of commands, along with the desired options, need to be specified in the BB_LOG_HOST_STAT_CMDS variable delimited by ; as such: BB_LOG_HOST_STAT_CMDS = "command1 ; command2 ;... ;" (From OE-Core rev: edb7098e9e0a8978568a45057c1c3ad2c6cacd67) Signed-off-by: Sakib Sajal Signed-off-by: Richard Purdie

buildstats.bbclass: Do not recalculate build start time

2020-06-04T12:27:32+00:00

The build start time is recorded in __timedata_build, which we should use rather than recalculating it. (From OE-Core rev: b723e9a4de67f33f61f2e7fe36ea451a46840b3e) Signed-off-by: Junling Zheng Signed-off-by: Richard Purdie
