Add DaikonGetopt, a Getopt subclass that throws a UserError describing an unrecognized, ambiguous, or malformed option and handles -h and --help. Use it in Daikon and in the other tools that use Getopt. Remove Diff's -u and -z options, which had no effect. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…per call Report a UserError for missing or non-integer num_reps and sample_size and for a malformed -SEED. Pass every argument that is not a TraceSelect option to Daikon rather than silently dropping some. mainHelper resets its static state on each call.

…menter argument errors on stderr, simplify ambiguity check

…enter -h to runtimechecker-options DaikonGetopt again provides nonOptionArgs, argsAfterLeadingOptions, a Supplier-based constructor, and setUsageHint, which codespecs#885-codespecs#888 use. The instrumenter's -h and --help handling belongs to codespecs#888.

- Line 171: Update the output capture in BadOptionTest to use the Java
8-compatible PrintStream constructor and replace the
ByteArrayOutputStream.toString(Charset) call with toString() for the
nonempty-output assertion.
Review comments at @java/daikon/tools/TraceSelect.java:
- Line 65: Update the usage example in TraceSelect to remove the extra .dtrace
filenames so the documented command uses only one trace file and can run
successfully.
- Around line 169-170: Update the TraceSelect option-parsing branches to run
only while `knowArgStart` is false, so once `--config` begins the Daikon
arguments, its filename is passed through unchanged even if it starts with a
dash. Preserve the existing handling of TraceSelect switches before that
boundary.

TraceSelect reports a
UserErrorfor missing or non-integernum_reps/sample_size, for a malformed-SEED, for a misspelled TraceSelect option, and for a compressed trace file. It checks all its arguments (and handles-hand--help) before sampling. It passes every argument that is not a TraceSelect option to Daikon rather than silently dropping some, and it keeps its state in local variables, somainHelpercan be called repeatedly.-SEEDnow takes effect, and a sample file left over from an earlier-NOCLEANrun is overwritten rather than partially overwritten.New method
DaikonGetopt.argsAfterLeadingOptionshandles the-hand--helpoptions that precede TraceSelect's other arguments. #888 adds the same method.🤖 Generated with Claude Code
