Move the implementation to C++ land. This is similar to commit 3f65916
but this time for the write() function and the Buffer(s, 'hex')
constructor.
Speeds up the benchmark below about 24x (2.6s vs 1:02m).
var s = 'f';
for (var i = 0; i < 26; ++i) s += s; // 64 MB
Buffer(s, 'hex');
If the NODE_DEBUGGER_TIMEOUT environment variable is set, then use
that as the number of ms to wait for the debugger to start.
This is primarily to work around a race condition that almost never
happens in real usage with the debugger, but happens EVERY FRACKING
TIME when the debugger tests run as part of 'make test'.
Move the implementation to C++ land. The old JS implementation used
string concatenation, was dog slow and consumed copious amounts of
memory for large buffers. Example:
var buf = Buffer(0x1000000); // 16 MB
buf.toString('hex') // Used 3+ GB of memory.
The new implementation operates in O(n) time and space.
Fixes#4700.
Those values, if passed to the _read() cb, will not signal an EOF. Only
null or undefined will mark the end of data, and trigger the end event.
However, great care must be taken if you are returning an empty string
or buffer! There must be some other thing somewhere that will trigger
a read() call, because there will never be a readable event fired later.
This is in preparation for CryptoStreams being ported to streams2, where
it is safe to simply stop reading, because the crypto cycle process will
cause it to read(0) again at some future date.
Make lines ending \r\n emit one 'line' event, not two (where the second
one is an empty string).
This adds a new keypress name: 'return' (as in: 'carriage return').
Fixes#3305.
This commit breaks simple/test-stream2-stderr-sync. Need to figure out
a better way, or just accept that `(function W(){stream.write(b,W)})()`
is going to be noisy. People should really be using the `'drain'` event
for this use-case anyway.
This reverts commit 02f7d1bfd8.
Always defer the _write callback. The optimization here was only
relevant in some oddball edge cases that we don't actually care about.
Our benchmarks confirm that just always deferring the Socket._write cb
is perfectly fine to do, and in some cases, even slightly more
performant.
When a datagram socket hasn't been bound yet, node will defer `send()`
operations until binding has completed. Before this patch a `listening`
listener would be installed every time `send` was called. This triggered
an EventEmitter leak warning when more than 10 packets were sent in a
tight loop. Therefore switch to using a single `listening` listener, and
use an array to enqueue outbound packets.
The refactor in b43e544140 to use
stream.push() in Transform inadvertently caused it to immediately
consume all the written data, regardless of whether or not the readable
side was being consumed.
Only pull data through the _transform() process when the readable side
is being consumed.
Fix#4667
TCPWrap::Initialize() and PipeWrap::Initialize() should be called before
any data will be read from received socket. But, because of lazy
initialization of these bindings, Initialize() method isn't called.
Init bindings manually upon socket receiving.
See #4669
Fix the following OOM error in pummel/test-net-connect-memleak
and pummel/test-tls-connect-memleak:
FATAL ERROR: CALL_AND_RETRY_0 Allocation failed - process out of
memory
Commit v8/v8@91afd39 increases the size of the deoptimization table
to the extent that a 64M float array pushes it over the brink. Switch
to SMIs so it stays below the limit.
pummel/test-net-connect-memleak is still failing albeit with a different
error this time. Needs further investigation.

If the end argument is omitted or not a number, make it default to
the end of the buffer, not zero.
Ideally, it should not matter what it defaults to because the JS shim
in lib/buffer.js should handle that but there are still several places
in node.js core that secrete SlowBuffers, hence Buffer::Copy() gets
called without going through Buffer.prototype.copy() first.
It's segfaulting in release mode and asserting in debug mode:
#
# Fatal error in ../../deps/v8/src/api.h, line 297
# CHECK(allow_empty_handle || that != __null) failed
#
This reverts commit 99f0b022d5.
Before sending handle to another process using uv_write2(), it should be
referenced to prevent it from being GCed before AfterWrite() will be
called.

Init functions now receive exports as the first argument, like
before, but also the module object as the second argument, if they
support it.

* Omit ToObject() call. Buffer::Data() and Buffer::Length() know how
to deal with Values.
* Don't check if the argument is undefined because it realistically
never is and undefined->integer coercion achieves the same thing.
Fix issue where SlowBuffers couldn't be passed as target to Buffer
copy().
Also included checks to see if Argument parameters are defined before
assigning their values. This offered ~3x's performance gain.
Backport of 16bbecc from master branch. Closes#4633.
Changed types of errors thrown to be more indicative of what the error
represents. Also removed a few unnecessary uses of the v8 fully
quantified typename.
Argument checks were simplified by setting all undefined/NaN or out of
bounds values equal to their defaults.
Also copy() tests had a flaw that each buffer had the same bit pattern at
the same offset. So even if the copy failed, the bit-by-bit comparison
would have still been true. This was fixed by filling each buffer with a
unique value before copy operations.

This adds a proxy for bytesWritten to the tls.CryptoStream. This
change makes the connection object more similar between HTTP and
HTTPS requests in an effort to avoid confusion.
