After socket.setEncoding(enc), socket.pipe(destination) wrote the raw
bytes it read to the destination. It now writes the decoded strings, as
Node's pipe writes each string chunk: the destination receives their
UTF-8 bytes, and a partial character the decoder holds at EOF is written
before the destination ends.
tests/node-parallel/run.mjs runs each job's files with its own
TEST_THREAD_ID, as Node's test runner does, so test/common/tmpdir gives
concurrent files different directories instead of one shared .tmp.0.
process.emitWarning checks its arguments in Node's order: an options
object replaces type with `options.type || "Warning"` and code with
`options.code`, type and code are checked before the warning and for
Error warnings too, an empty type names the warning "Warning", and a
DeprecationWarning type returns at once under process.noDeprecation.
Wrong kinds throw ERR_INVALID_ARG_TYPE with Node's "Received ..." tail.
An instance of an Error subclass is an Error warning, and a typed record
in the options position is read as the options object. The default
report reads the warning's message, code and detail as property reads
do, so an Error subclass's own code is reported. A deprecation thrown
under process.throwDeprecation is thrown as the Error it encodes, so the
uncaught report names it.
process.kill throws ERR_UNKNOWN_SIGNAL for an unknown signal name, as
subprocess.kill does, and a failed kill(2) is Node's errnoException with
errno, code and syscall. A failed process.chdir names the working
directory as path and the target as dest.
os.userInfo() reads the passwd entry of the effective uid: uid and gid
are the entry's pw_uid and pw_gid (-1 on Windows), not the process ids.
os.homedir() answers $HOME whenever it is set, an empty value included.
The minimal test/common for Node's test/parallel files gains isAIX,
isIBMi and isSunOS.
A run that a signal ends has a null exit code, so the runner recorded a
pass when Node and the executable ended by different signals, or when one
ended by a signal and the other with an exit code compared as null. The
verdict now compares both the exit code and the signal (verdict.mjs), and
records Node's signal in nodeExit as it does for the executable.
A relative --node path also made the minimal lane's fixtures symlink
relative to the copied tree, where it does not resolve. The checkout path
is now resolved first.
tests/harness/node-parallel-runner.test.ts covers both: the termination
comparison, and a relative --node path whose fixtures resolve from the
minimal tree.
tests/node-parallel/run.mjs builds files from a Node.js checkout's
test/parallel with scriptc, runs each executable in that directory, and
compares its exit status with Node's, writing a pass, fail or refused
verdict and the first error line per file (results.json, results.md).
--common minimal (the default) runs the files against a minimal
test/common (common/index.cjs, common/wpt.cjs) whose helpers keep Node's
semantics, so a verdict measures the module under test; --common node
uses Node's own test/common.
