Great job.
I feel the first commit looks good and sufficient, and the subsequent changes can be discarded.

Thanks @hongzhidao ! |
Both clang-analyzer and coverity flagged an issue in nxt_term_parse() that we set 'state = st_letter' but then set it to 'state = st_space' before using it. While we could simply remove the first assignment and placate the analyzers, upon further analysis it seems that there is some more cleanup that could be done in this function. This commit addresses the above issue, subsequent commits will continue the cleanup. To solve the unused assignment issue we can get rid of the 'state == st_letter' assignment and unconditionally execute the code that was behind the if (state != st_letter) { guard. If we're not handling a space then we should have either a digit or letter. Also, perhaps more importantly, this if () statement would never be false at this point as state would never == st_letter. We may as well also remove the st_letter enum value. The src/test/nxt_term_parse_test.c still passes tests: [notice] term parse test passed NOTE: Although this function is not currently used in Unit (only by src/test/nxt_term_parse_test.c), it is probably worth cleaning it up and solving one of the open clang-analyzer (and coverity) issues.

The function nxt_term_parse() is able to take strings with trailing whitespace e.g. "1w1d ", add a test case to cover such things. Signed-off-by: Andrew Clayton <[email protected]>
