When there is an error that is thrown in a nextTick function, which is
then handled by a domain or other process.on('uncaughtException')
handler, if the error handler *also* adds a nextTick and triggers
multiple MakeCallback events (ie, by doing some I/O), then it would
skip over the tickDepth check, resulting in an infinite spin.
Solution: Check the tickDepth at the start of the tick processing, and
preserve it when we are cleaning up in the error case or exiting early
in the re-entry case.
In order to make sure that tick callbacks are *eventually* handled, any
callback triggered by the underlying spinner in libuv will be processed
as if starting from a tick depth of 0.
* When the process is already dead, but the `exit` signal wasn't raised
yet, the ESRCH error should be ignored.
* When an invalid signal is specified, kill() should throw.
* Like process.kill(), child_process.kill() now preserves a `0` signal
which can be used to check the liveliness of the child process.
* process.kill() and child_process.kill() will now return true if the
signal was actually delivered, and false otherwise.
* When an `exec`-ed process is automatically killed because a time or
buffer limit is exceeded, and the kill() fails, this error should be
reported through the `exec` callback.
Fixes: #3409
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.
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.
This patch now reports the proper throw call site for exceptions
triggered within process.nextTick. So instead of this:
node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
^
You will now see:
mydir/myscript.js:15
throw new Error('My Error');
^
From my testing this patch causes no performance regressions, but does
greatly simplify processing the nextTickQueue.
Reusing the same logic for both places for the behavior is consistent.
For example:
$ ./node -p -e "'Hello World'"
Hello World
$ echo "'Hello World'" | ./node -p
Hello World
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
This should only be minimally used, since the `terminal` value will usually be
what you are expecting. This option is specifically for the case where `terminal`
is false, but you still want colors to be output (or vice-versa).
The overall goal here is to make readline more interoperable with other node
Streams like say a net.Socket instance, in "terminal" mode.
See #2922 for all the details.
Closes#2922.
This is the JS representation of the `config.gypi` file that was used when
compiling node. With this information, you can tell whether the current node
binary has shared or static dependencies, or any other configuration options
that may have been used.
This reverts commit b0c1541227.
Reverted commit introduced a regression causing `process.argv[0]` to be
invalid in node processes spawned from `PATH` (without explicit path to
executable file - for example when using global node installation).
Instead of finding a correct path to the executable, `process.cwd()`
would be prepended to `process.argv[0]`.
These methods were removed a long time ago. Keeping these notices here
makes no sense anymore.
Also, removing this part of code slightly speeds up the startup.
It was decided that the performance benefits that isolates offer (faster spin-up
times for worker processes, faster inter-worker communication, possibly a lower
memory footprint) are not actual bottlenecks for most people and do not outweigh
the potential stability issues and intrusive changes to the code base that
first-class support for isolates requires.
Hence, this commit backs out all isolates-related changes.
Good bye, isolates. We hardly knew ye.
Also, if an error is already provided, then raise the provided
error, rather than throwing it with a less helpful 'stdout cannot
be closed' message.
This is important for properly handling EPIPEs.
