buildman: Use git worktrees instead of git clones when possible

2020-09-22T18:50:43Z

This patch makes buildman create linked working trees instead of clones of the source repository, but keeps updating the older clones of the repository that might already exist. These worktrees share "everything except working directory specific files such as HEAD, index, etc." with the source repository. See the git-worktree(1) manual page for more information. If git-worktree isn't available, silently falls back to cloning the repository. Signed-off-by: Alper Nebi Yasak Reviewed-by: Simon Glass Tested-by: Simon Glass

buildman: Show the build rate at the end

2020-07-29T01:30:39Z

It is interesting to note the number of builds completed per second to track machine performance and build speed. Add a 'rate' value at the end of the build to show this. Signed-off-by: Simon Glass

buildman: Remove _of_#_ from results directory paths

2020-06-12T02:52:11Z

Currently, the following scenario will rebuild the first commit even though it is not really necessary - the commit sha or the position in the patchset did not change: $ git am $ tools/buildman/buildman -P -E -W -b master mx6 $ git am $ tools/buildman/buildman -P -E -W -b master mx6 <- will rebuild the first commit as well, even though nothing has changed about it. This is due to the fact that previous results directories get removed when the number of commits change. By removing the _of_#_ part of the directory path, the commits will be rebuilt only if the commit sha or the position in the patchset changes. Also, update the testcase to reflect this change.

patman: Move to absolute imports

2020-04-26T20:25:21Z

At present patman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move patman to use absolute imports. This requires changes in tools which use the patman libraries (which is most of them). Signed-off-by: Simon Glass

buildman: Move to absolute imports

2020-04-26T20:25:21Z

At present buildman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move buildman to use absolute imports. Also adjust moveconfig.py too since it uses some buildman modules and cannot work without this. Signed-off-by: Simon Glass

buildman: Write output files when using -w

2020-04-26T20:24:08Z

At present buildman does not write its own output files (err, done, the environment) when using -w. However this is useful for when the build is run with -s to check it. In fact ProduceResultSummary() reads the result from those files rather than using the 'result' info directly. So ProcessResult() does not work with -w at present. It does not print any output. Fix this by writing output files even when -w is used. Signed-off-by: Simon Glass

buildman: Add an option to ignore migration warnings

2020-04-21T12:33:47Z

These are becoming more common now. They cause boards to show warnings which can be mistaking for compiler warnings. Add a buildman option to ignore them. This option works only with the summary option (-s). It does not affect the build process. Signed-off-by: Simon Glass

buildman: Add an option to ignore device-tree warnings

2020-04-21T12:33:47Z

Unfortunately the plague of device-tree warnings has not lifted. These warnings infiltrate almost every build, adding noise and confusion. Add a buildman option to ignore them. This option works only with the summary option (-s). It does not affect the build process. Signed-off-by: Simon Glass

buildman: Make -I the default

2020-04-21T12:33:47Z

At present buildman defaults to running 'mrproper' on every thread before it starts building commits for each board. This can add a delay of about 5 seconds to the start of the process, since the tools and other invariants must be rebuilt. In particular, a build without '-b', to build current source, runs much slower without -I, since any existing build is removed, thus losing the possibility of an incremental build. Partly this behaviour was to avoid strange build-system problems caused by running 'make defconfig' for one board and then one with a different architecture. But these problems were fixed quite a while ago. The -I option (which disabled mrproper) was introduced four years ago and does not seem to cause any problems with builds. So make -I the default and deprecate the option. To allow use of 'mrproper', add a new -m flag. Signed-off-by: Simon Glass

buildman: Show a summary of the build result

2020-04-21T12:33:47Z

When buildman finishes it leaves the last summary line visible, which shows the number of successful builds, builds with warnings and builds with errors. It is useful also to see how many builds were done in total along with the time taken. Show these on a separate line before buildman finishes. Signed-off-by: Simon Glass
