In case a worker would spawn a new subprocess with process.env, NODE_UNIQUE_ID
would have been a part of the env. Making the new subprocess believe it is a
worker, this would result in some confusion if the subprocess where to listen to
a port, since the server handle request would then be relayed to the worker.
This patch removes the NODE_UNIQUE_ID flag from process.env on startup so any
subprocess spawned by a worker is a normal process with no cluster stuff.
request.end() would sometimes try to write a zero-length buffer to the socket.
Don't do that, it triggers an unnecessary EPIPE when the other end has closed
the connection.
Fixes#3257.
* process._getActiveHandles() returns a list containing all active handles
(timers, sockets, etc.) that have not been unref'd.
* process._getActiveRequests() returns a list of active requests (in-flight
actions like connecting to a remote host, writing data to a socket, etc.).
child_process.fork() support sending native hander object, this patch add support for sending
net.Server and net.Socket object by converting the object to a native handle object and back
to a useful object again.
Note when sending a Socket there was emitted by a net Server object, the server.connections
property becomes null, because it is no longer possible to known when it is destroyed.
Prevents accidental inheritance by child processes. If the child process is a
node process, it would try to set up a channel with the parent and consequently
never quit because the channel kept the event loop alive.
Fixes#3240.
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.
* Calling fs.ReadStream.destroy() or fs.WriteStream.destroy() twice would close
the file descriptor twice. That's bad because the file descriptor may have
been repurposed in the mean time.
* A bad value check in fs.ReadStream.prototype.destroy() would prevent a stream
created with fs.createReadStream({fd:0}) from getting closed.
Upon "normal" exiting of Node (i.e. the event loop completes naturally),
the "code" parameter was not being passed to the "exit" event listeners.
Be consistent. Tests included.
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
