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.
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
Apparently, context->Global() won't be destroyed if the context itself
isn't marked as weak and independent.
Also, the weakness flag should be cleared once the weak callback is
executed, otherwise we'll get crashes in Debug builds.
fix#6115 and #6201
The `options` that were being passed in before here are specific to a
single request, which kinda defeats the purpose of using an Agent in the
first place.
On a worse note, these `options` have not yet been "processed" by the
`http.ClientRequest` class, so if `port: null` is set (like it is as the
result of a `url.parse()` call), then they take preference over the
processed values since the agent's "options" get mixed in last in the
`createSocket()` function.
Fixes#6197.
Fixes#6199.
Closes#6231.
Otherwise the data ends up "on the wire" twice, and
switching between consuming the stream using `ondata`
vs. `read()` would yield duplicate data, which was bad.
Functions created using: `vm.runInNewContext('(function() { })')` will
reference only `proxy_global_` object and not `sandbox_`. Thus in case,
where there're no references to sandbox (such as in example above),
`ContextifyContext` will be destroyed and use-after-free might happen.
The NPN protocols was set on `require('tls')` or `global` object instead
of being a local property. This fact lead to strange persistence of NPN
protocols, and sometimes incorrect protocol selection (when no NPN
protocols were passed in client options).
fix#6168
Slowness being somewhat subjective but determined by running the
test suite a few times and picking off everything that consistently
clocks in at 2 seconds or more.
Honorable mention for simple/test-tls-server-large-request, it often
runs for 10 (!) seconds or more.
Since it is Unix tradition to use exit code 1 for general-purpose script
bail-out, and the way of doing that in Node is to throw an exception and
not catch it, it makes the most sense to exit with 1 when an exception
goes uncaught.
Move the `Invalid Argument` exit to 9, so that it's something specific,
and clear that it's a node internal error.
Also, document the exit codes that we use.
From commit 756ae2c all the WRAP/UNWRAP were moved to a single location
for ease of use. In a single location NO_ABORT should have been used but
wasn't. This caused HandleWrap::Close to abort. Below is the applicable
code change as demonstration there was no abort specified when
unwrapping the object.
void HandleWrap::Close(const FunctionCallbackInfo<Value>& args) {
HandleScope scope(node_isolate);
- HandleWrap *wrap = static_cast<HandleWrap*>(
- args.This()->GetAlignedPointerFromInternalField(0));
+ HandleWrap* wrap;
+ UNWRAP(args.This(), HandleWrap, wrap);
Also included a test that will reproduce the abort.
In cases where the Agent has maxSockets=Infinity, and
keepAlive=false, there's no case where we won't immediately close the
connection after the response is completed.
Since we're going to close it anyway, send a `connection:close` header
rather than a `connection:keep-alive` header. Still send the
`connection:keep-alive` if the agent will actually reuse the socket,
however.
Closes#5838
Adding a new `repl-harmony` test file here because adding the
`--use_strict --harmony` flags on the main repl test file was causing
lots of unrelated failures, due to global variable assignments and
things like that. This new test file is based off of the original
repl.js test file, but has a lot of the tests stripped out. A test case
for this commit is included though.
Fixes#6132.
Replace the growing list of 'isSyntaxError' whackamole conditions with a
smarter approach. This creates a vm Script object *first*, which will
parse the code and raise a SyntaxError right away.
We still do need the test function, but only because strict mode syntax
errors are not recoverable, and should be raised right away. Really, we
should probably *only* continue on "unexpected end of input" SyntaxErrors.
Also fixes a very difficult-to-test nit where the '...' indentation is
not properly cleared when you ^C out of a syntax error.
Closes#6093
This is useful when we need to push some debugging messages out to
stderr, without going through the Writable class, or triggering any kind
of nextTick or callback behavior.
* Exit with an error message when the option is not a node or V8 option.
* Remove the option_end_index global. Needs to happen anyway for
the multi-context work, might as well land it in master now.
* Add a smidgen of const-correctness.
* Pay off a few years of accrued technical debt.
Don't wait a full second before starting the watcher, 10 ms ought to be

This change is not entirely ready for prime time: it's making ~50 tests
fail on Windows, mostly due to timeouts. It's up for debate who is
at fault here: node.js or libuv.
It does however expose a libuv bug on OS X, where the event loop
sometimes gets stuck in uv__io_poll() when there is a single
UV_SHUTDOWN request left in the queue. Needs further investigation.
This reverts commit 4915884da6.
Commit 556b890 added a call to uv_loop_delete() with the intent of
catching handle lifecycle bugs. It worked because it exposed one:
process.on('exit', function() {
console.log('bye'); // Asserts.
});
When run, it asserts with the following message:
Assertion failed: (!uv__has_active_reqs(loop)), function
uv__loop_delete, file ../deps/uv/src/unix/loop.c, line 150.
That's because libuv as of joyent/libuv@3f2d4d5 checks that there are
no in-flight requests when the event loop is destroyed. In the test
case above, the write request for the string hasn't completed yet by
the time node.js exits: the string itself has most likely been written
but libuv hasn't had the opportunity to return the write request to
node.js.
That's why this commit adds a cleanup step right before exit where it
explicitly closes all open handles, then waits until the event loop
exits naturally.
Named pipes (UNIX domain sockets) are shut down first in order to flush
pending write requests. Should go some way towards fixing the Windows
issue where output on stdout/stderr sometimes gets truncated.
Fixesjoyent/libuv#911.
Passing a filename is still supported in place of certain options
arguments, for backward-compatibility, but timeout and display-errors
are not translated since those were undocumented.
Also managed to eliminate an extra stack trace line by not calling
through the `createScript` export.
Added a few message tests to show how `displayErrors` works.
In `Timer.now` always update the loop time by calling uv_update_time.
Previously we were trying to cache the loop time to prevent extra
syscalls. While a noble goal, it can cause timers to fire early in
certain circumstances. Especially seen in cpu bound work loads or work
loads with synchronous file operations.
Previously, calling `vm.createContext(o)` repeatedly on the same `o`
would cause new C++ `ContextifyContext`s to be created and stored on
`o`, while the previous resident went off into leaked-memory limbo.
Now, repeatedly trying to contextify a sandbox will do nothing after
the first time.
To detect this, an independently-useful `vm.isContext(sandbox)` export
was added.
Since the encoding is no longer relevant once it is decoded to a Buffer,
it is confusing and incorrect to pass the encoding as 'utf8' or whatever
in those cases.
Closes#6119
This is an important part of the repl use-case.
TODO: The arg parsing in vm.runIn*Context() is rather wonky.
It would be good to move more of that into the Script class,
and/or an options object.
As documented in #3042 and in [1], the existing vm implementation has
many problems. All of these are solved by @brianmcd's [contextify][2]
package. This commit uses contextify as a conceptual base and its code
core to overhaul the vm module and fix its many edge cases and caveats.
Functionally, this fixes#3042. In particular:
- A context is now indistinguishable from the object it is based on
(the "sandbox"). A context is simply a sandbox that has been marked
by the vm module, via `vm.createContext`, with special internal
information that allows scripts to be run inside of it.
- Consequently, items added to the context from anywhere are
immediately visible to all code that can access that context, both
inside and outside the virtual machine.
This commit also smooths over the API very slightly:
- Parameter defaults are now uniformly triggered via `undefined`, per
ES6 semantics and previous discussion at [3].
- Several undocumented and problematic features have been removed, e.g.
the conflation of `vm.Script` with `vm` itself, and the fact that
`Script` instances also had all static `vm` methods. The API is now
exactly as documented (although arguably the existence of the
`vm.Script` export is not yet documented, just the `Script` class
itself).
In terms of implementation, this replaces node_script.cc with
node_contextify.cc, which is derived originally from [4] (see [5]) but
has since undergone extensive modifications and iterations to expose
the most useful C++ API and use the coding conventions and utilities of
Node core.
The bindings exposed by `process.binding('contextify')`
(node_contextify.cc) replace those formerly exposed by
`process.binding('evals')` (node_script.cc). They are:
- ContextifyScript(code, [filename]), with methods:
- runInThisContext()
- runInContext(sandbox, [timeout])
- makeContext(sandbox)
From this, the vm.js file builds the entire documented vm module API.
node.js and module.js were modified to use this new native binding, or
the vm module itself where possible. This introduces an extra line or
two into the stack traces of module compilation (and thus into most
stack traces), explaining the changed tests.
The tests were also updated slightly, with all vm-related simple tests
consolidated as test/simple/test-vm-* (some of them were formerly
test/simple/test-script-*). At the same time they switched from
`common.debug` to `console.error` and were updated to use
`assert.throws` instead of rolling their own error-testing methods.
New tests were also added, of course, demonstrating the new
capabilities and fixes.

`dns.lookup` defaults to selecting IPv4 record even if IPv6 is available
for the desired zone. Generally, this approach works, but if IPv4
address is unavailable - there'll be no other way to opt-out and connect using
IPv6 address than calling `dns.lookup` and passing it to `.connect()`
directly.
This commit adds `family` option to `net.connect` method to figure out
this issue.
