When building custom `node` versions (e.g., floating features/fixes from
different versions) it's often useful to specify a custom tag which
easily identifies build when invoking `node -v`.
Introduce a way to specify this tag in `node_version.h` file or by
running `./configure --tag="<tag>"`. Insert it right after the patch
version (and before `-pre`, if build is not a release).
Closes#4452.
Fixes#3226.
Consider a production server that uses a REPL to debug. Creating the instance
would wipe out the global cache of modules, and subsequent "require" calls in
the server would be reloaded from disk. The REPL should observe only, without
altering, its environment.
Starting a line with `**bold**` text makes it think that it's a link,
and get confused.
This should really be fixed properly in the doc generator, but for now,
it's not a major issue. It's probably just a matter of updating marked.
When perlasm generates MASM code it sets the assembler target to 468.
In this mode MASM refuses to assemble a couple of instructions. Bumping
the target to 686 solves this problem.
This patch brings the openssl library that is built with gyp closer
to what the standard build system produces.
All opensslconf.h versions are now merged into a single file, which
makes it easier for compiled addons to locate this file.
Apply the same optimization to res.end(buf) that is applied to res.end(str).
Speeds up `node benchmark/http_simple_auto -k -c 1 -n 25000 buffer/1`
(non-chunked response body) by about 750x. That's not a typo.
Chunked responses:
$ cat tmp/http-chunked-client.js
// Run `node benchmark/http_simple` in another terminal.
var http = require('http'), url = require('url');
var options = url.parse('http://127.0.0.1:8000/buffer/1/1');
options.agent = new http.Agent({ maxSockets: 1 });
for (var i = 0; i < 25000; ++i) http.get(options);
Before:
$ time out/Release/node tmp/http-chunked-client.js
real 16m40.411s
user 0m9.184s
sys 0m0.604s
After:
$ time out/Release/node tmp/http-chunked-client.js
real 0m5.386s
user 0m2.768s
sys 0m0.728s
That's still a 185x speed-up.
Fixes#4415.
This is very similar to http.sh, but generates a flamegraph
with dtrace, pruning off the single-hit stacks so that we can
more easily see the places where relevant amounts of time are
spent.
Remove the idle garbage collector. Its purpose was to run the garbage collector
when the application is idle but it never worked quite right. Many people have
complained over the years that with heaps > 128 MB, a node.js process never
sleeps anymore; instead, it spends nearly 100% of its CPU time trying to
collect garbage.
Back in the old days, idle GC probably was a good idea. But with V8's current
incremental collector, idle gc appears to offer no time or space benefits
whatsoever and indeed seems actively harmful. Remove it.
Fixes#3870.
Although it is not used externally by node, it is needed by upstream and Plask.
This effectively reverts:

typed arrays: unexport SizeOfArrayElementForType()
It isn't used anywhere else, so made it an implementation detail in
v8_typed_array.cc.
