Remove the need to call start/stop the uv_idle spinner between
MakeCallbacks. The one place where the tick processor needs to be kicked
is where a user catches uncaughtException. For that we'll now use
setImmediate, which accomplishes the same task.
maxTickDepth checks have been removed for domains and replaced with a
flag that checks if the last callback threw. If it did then execution of
the remaining tickQueue is deferred to the spinner.
This is to prevent domains from entering a continuous loop when an error
callback also throws an error.
Removes the check for maxTickDepth for non-domain callbacks. So a user
can starve I/O by setting a recursive nextTick.
The domain case is more complex and will be addressed in another commit.
Previous code was calling uv_loop_delete() directly on a running loop,
which led to race condition aborts/segfaults within libuv. This change
changes the watchdog thread to call uv_run() with UV_RUN_ONCE so that
the call exits after either the timer times out or uv_async_send() is
called from the main thread in Watchdog::Destroy(). The timer/async
handles are then closed and uv_run() with UV_RUN_DEFAULT is called so
that libuv has a chance to cleanup before the thread exits. The main
thread meanwhile calls uv_thread_join() and then uv_loop_delete() to
complete the cleanup.
Quote from SSL_shutdown man page:
The output of SSL_get_error(3) may be misleading,
as an erroneous SSL_ERROR_SYSCALL may be flagged even though
no error occurred.
Also, handle all other errors to prevent assertion in `ClearError()`.
This saves a few calls to gettimeofday which can be expensive, and
potentially subject to clock drift. Instead use the loop time which
uses hrtime internally.
fixes#5497
Because of variations in different base64 implementation, it's been
decided to strip all padding from the end of a base64 string and
calculate its size from that.
Instead of String::New every time, use a Persistent sym. This can be
accomplished in two ways:
1) Local<String> str = *persistent_str_sym;
2) Handle<String> str = persistent_str_sym;
I've chosen to use the latter method for simplicity's sake.
Other small changes include creating syms on Initialize and removing
unnecessary Local casting on return values.
The default encoding is 'buffer'. When the input is a string, treat it
as 'binary'. Fixes the following assertion:
node: ../src/string_bytes.cc:309: static size_t
node::StringBytes::StorageSize(v8::Handle<v8::Value>, node::encoding):
Assertion `0 && "buffer encoding specified but string provided"'
failed.
Introduced in 64fc34b2.
Fixes#5482.
getServers returns an array of ips that are currently being used for
resolution
setServers takes an array of ips that are to be used for resolution,
this will throw if there's invalid input but preserve the original
configuration
This also templatizes the Buffer::*Slice functions, and the template
function probably cannot be safely used outside of Node. However, it
also SHOULD not be used outside of Node, so this is arguably a feature
as well as a caveat.
