Add a short explanation of what the load average is and why it's
unavailable on Windows.
Also sneak in a fix for a typo that I introduced in commit 56c5806.
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.
* Extend examples to show how to handle non-constructor invocation in
constructor callback functions.
* Fix up examples to initialize member variables at object construction.
* Fix up a few naming inconsistencies.
Fixes#5701.
Destroying the TLS session implies destroying the underlying socket but
before this commit, that was done with net.Socket#destroy() rather than
net.Socket#destroySoon(). The former closes the connection right away,
even when there is still data to write. In other words, sometimes the
final TLS record got truncated.
Fixes#6107.
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
fs.truncate() and its synchronous sibling are implemented in terms of
open() + ftruncate(). Unfortunately, it opened the target file with
mode 'w' a.k.a. 'write-only and create or truncate at open'.
The subsequent call to ftruncate() then moved the end-of-file pointer
from zero to the requested offset with the net result of a file that's
neatly truncated at the right offset and filled with zero bytes only.
This bug was introduced in commit 168a5557 but in fairness, before that
commit fs.truncate() worked like fs.ftruncate() so it seems we've never
had a working fs.truncate() until now.
Fixes#6233.
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.
