This is an incredibly useful thing to know about, and it
will likely never change. I can't remember why we
didn't ever document it, and people keep suggesting we
do so.
Regarding discussion in #3198. Passing the worker as an argument
to an event emitted on the worker is redundant, and an unnecessary
break in consistency vs the events on the ChildProcess objects.
It was removed from 'exit', but 'listening' and others were
overlooked. This corrects that oversight.
test: fixes due to new cluster api.
- changed worker `death` to `exit`.
- corrected argument type expected by worker `exit` handler.
test: more tests of cluster.worker death
cluster: fixed arguments on worker 'exit' event
worker 'exit' event now emits arguments consistent with the
corresponding event in child_process module.
This is a squashed commit of the main work done on the domains-wip branch.
The original commit messages are preserved for posterity:
* Implicitly add EventEmitters to active domain
* Implicitly add timers to active domain
* domain: add members, remove ctor cb
* Don't hijack bound callbacks for Domain error events
* Add dispose method
* Add domain.remove(ee) method
* A test of multiple domains in process at once
* Put the active domain on the process object
* Only intercept error arg if explicitly requested
* Typo
* Don't auto-add new domains to the current domain
While an automatic parent/child relationship is sort of neat,
and leads to some nice error-bubbling characteristics, it also
results in keeping a reference to every EE and timer created,
unless domains are explicitly disposed of.
* Explicitly adding one domain to another is still fine, of course.
* Don't allow circular domain->domain memberships
* Disposing of a domain removes it from its parent
* Domain disposal turns functions into no-ops
* More documentation of domains
* More thorough dispose() semantics
* An example using domains in an HTTP server
* Don't handle errors on a disposed domain
* Need to push, even if the same domain is entered multiple times
* Array.push is too slow for the EE Ctor
* lint domain
* domain: docs
* Also call abort and destroySoon to clean up event emitters
* domain: Wrap destroy methods in a try/catch
* Attach tick callbacks to active domain
* domain: Only implicitly bind timers, not explicitly
* domain: Don't fire timers when disposed.
* domain: Simplify naming so that MakeCallback works on Timers
* Add setInterval and nextTick to domain test
* domain: Make stack private
* Update npm to 1.1.16
* Show licenses in binary installers.
* unix: add uv_fs_read64, uv_fs_write64 and uv_fs_ftruncate64 (Ben Noordhuis)
* add 64bit offset fs functions (Igor Zinkovsky)
* windows: don't report ENOTSOCK when attempting to bind an udp handle twice (Bert Belder)
* windows: backport pipe-connect-to-file fixes from master (Bert Belder)
* windows: never call fs event callbacks after closing the watcher (Bert Belder)
* fs.readFile: don't make the callback before the fd is closed (Bert Belder)
* windows: use 64bit offsets for uv_fs apis (Igor Zinkovsky)
* Fix#2061: segmentation fault on OS X due to stat size mismatch (Ben Noordhuis)
Technically saying `tty.ReadStream#setRawMode()` is correct,
but since a typical use cannot instantiate `tty.ReadStream` themselves,
and 99% of the time the only instance is `process.stdin`,
then a little clarification seemed necessary.
