Don't emit the 'disconnect' event until all workers have gone away.
Before this commit, the event was emitted when all open handles were
closed, which usually - but not always - amounts to the same thing.
Fixes#6346.
Because it's possible for the data within a Buffer instance to be
altered after instantiation, or in case a user attempts to do something
like the following:
Buffer.prototype.fill.call({}, 10, 0, 10);
It doesn't result in a segfault.
This change makes several improvements to the ustack helper and MDB
support:
- ustack helper and MDB: add support for two-byte strings
(necessary to print many filenames in stacktraces in 0.10 and later).
- ustack helper: fix position numbers, which were off by a factor of two
- ustack helper: fix frames with undefined Scripts (e.g., "RegExp")
- ustack helper: add stub frames
- MDB: add support for sliced strings
- MDB: sync up with changes from the illumos version of the module
Fixes#6309Closes#6318
Mea culpa, I didn't properly resolve a merge conflict in the last two
commits. The resulting segmentation fault only happened on Linux and
only sometimes.
Fixes#6306.
The previous commit changes the profiler idle notifier so that it only
gets started when a --prof or --prof_lazy argument is specified on the
command line.
This commit adds two internal methods to the process object that allows
one to start and stop the idle notifier programmatically.
The previous commit adds a notifier that tells the V8 profiler when
node.js is idle, i.e. when it's about to start sleeping in the
platform's equivalent of epoll_wait().
This commit adds a heuristic that only starts the notifier when the
V8 profiler is started from the command line.
Inform V8's CPU profiler when we're idle. The profiler is
sampling-based but not all samples are created equal; mark the wall
clock time spent in epoll_wait() and friends so profiling tools can
filter it out. The samples still end up in v8.log but with state=IDLE
rather than state=EXTERNAL.
I haven't actually tested this code, but was reading it due to a
post that linked to the code here:
http://dailyjs.com/2013/09/26/libuv/
As I was reading through the code, I noticed a path that can't
be reached.
I didn't strictly follow the contributing guide:
https://github.com/joyent/node/wiki/Contributing
but the change seems safe.
Feel free to close this out. I'm not sure if it was just an oversight
or what.
Drop the ObjectWrap dependency in favor of an internal WeakObject class.
Let's us stop worrying about API and ABI compatibility when making
changes to the way node.js deals with weakly persistent handles
internally.
After the upgrade from 3.20.17.7 to 3.20.17.11, we've begun hitting
random assertions in V8 in memory-constrained / GC-heavy situations.
The assertions all seem to be related to heap allocations and garbage
collection but apart from that, they're all over the place.
This reverts commit 970bdccc38.
The default entropy source is /dev/urandom on UNIX platforms, which is
okay but we can do better by seeding it from OpenSSL's entropy pool.
On Windows we can certainly do better; on that platform, V8 seeds the
random number generator using only the current system time.
Fixes#6250.
The test case from the previous commit exposed a regression in the way
that c-ares errors are reported to JS land. Said regression was
introduced in commit 756b622 ("src: add multi-context support").
Fixes the following test failure:
$ out/Release/node test/simple/test-dns-regress-6244
util.js:675
var errname = uv.errname(err);
^
Error: err >= 0
at Object.exports._errnoException (util.js:675:20)
at errnoException (dns.js:43:15)
at Object.onresolve [as oncomplete] (dns.js:145:19)
lib/dns.js erroneously assumed that the error code was a libuv error
code when it's really a c-ares status code. Libuv handles getaddrinfo()
style lookups (which is by far the most common type of lookup), that's
why this bug wasn't discovered earlier.
Don't forget to initialize the c-ares task tree head when creating a
new Environment. Oversight from the multi-context work that landed
in commit 756b622.
Fixes#6244.
Fix "Assertion failed" when trying to connect to non-int ports:
Assertion failed: (args[2]->Uint32Value()), function Connect,
file ../src/tcp_wrap.cc, line 379.
Abort trap: 6
