From: Simon Glass <simon.glass@canonical.com> After a few weeks of using this tool a couple of things have come to light, mostly in a recent attempt to cherry-pick ~260 commits. Firstly, it is hard to manually check a cherry-pick against the original. The GitLab GUI allows you to click on both, but it does not give a sense of the detail. Secondly, commits have sometimes already been applied to the tree, but in this case effort is still paid to cherry pick it, sometimes with unfortunate results. Thirdly, building once at the end does not catch every problems. In the case in question, about five commits were mangled, three of which would have been caught by doing a build. This series introduces a new 'check' command which provides a simple check of the diff delta between an original commit and its cherry pick., thus providing a list of suspect cherry-picks, e.g. (omitting some long lines): Cherry-pick Delta% Original Subject ----------- ------ ---------- ------- aaea489b2a 100 9bab7d2a7c net: wget: let wget_with_dns work with e557daec17 100 f0315babfb hash: Plumb crc8 into the hash functions 08a86f1769 40 6acada5daa configs: j7*: Enable TI_COMMON_CMD_OPTIONS de37f6abb6 100 fc37a73e66 fdt: Swap the signature for d1437b065a 100 e2cc9b4fc1 tools: binman: add 'fit, encrypt' property 09b800b0df 100 12d7be498a Docker/CI: Only test Xtensa on amd64 hosts 0256d8140c 100 ece1631f5e test/cmd/wget: replace bogus response with e005799d8f 33 15e0c5e390 lmb: Remove lmb_alloc_addr_flags() eaba5aae8f 79 99afa58e6d sandbox: Correct guard around readq/writeq c347fb4b1a 41 99145eec2d x86: select CONFIG_64BIT for X86_64 14192a60e0 89 60a684e0a9 trace: add support for 'trace wipe' 8f58cfe76d 66 905204ddcf test: test_trace.py: test 'trace wipe' 12 problem commit(s) found The -d option shows a diff of the patch diffs, which can aid a fast review. This series also includes some updates to the agent prompt to build after each commit, some refactoring and tidy-ups to remove pylint warnings and a way to tell the agent about possible already-applied commits. Further refinements will likely be needed as time goes on.
