Make `fs.createReadStream({ end: 42 })` work.
Before this commit, it worked only when used like this:
`fs.createReadStream({ start: 0, end: 42 })` - only when `start` was specified
by the caller.
Fixes#4423.
Enable long stacktraces if NODE_DEBUG=fs is set in the environment. Only
applies to the default rethrow callback; it's to help you find places where
you forgot to pass in a callback.
Use a default callback if the user omitted one. Avoids errors like the one
below:
fs.js:777
if (err) return callback(err);
^
TypeError: object is not a function
at fs.appendFile (fs.js:777:21)
at Object.oncomplete (fs.js:297:15)
This commit fixes the behavior of fs.lchmod(), fs.lchown() and fs.readFile()
when the callback is omitted. Before, they silently swallowed errors.
Fixes#4352.
Make sure the deletion event gets reported in the following scenario:
1. Watch a file.
2. The initial stat() goes okay.
3. Something deletes the watched file.
4. The second stat() fails with ENOENT.
The second stat() translates into the first 'change' event but a logic error
stopped it from getting emitted.
Fixes#4027.
Fixes a minor oversight introduced in 168a555, resulting in the following error:
fs.js:467
return fs.ftruncateSync(path, len, callback);
^
ReferenceError: callback is not defined
at Object.fs.truncateSync (fs.js:467:40)
The destroy() method of fs.ReadStream and fs.WriteStream takes a callback.
It's a leftover from the node 0.1 days, undocumented and not part of the
streams API. Remove it.
Before this commit, `fs.unwatchFile(path)` removed *all* listeners for `path`.
The function is overloaded now: `fs.unwatchFile(path)` still removes all
listeners, but `fs.unwatchFile(path, cb)` lets you remove a specific listener.
Fixes#3660.
There is no need for fs.readFile() to be using pread rather than read.
The default semantics of read() are such that subsequent reads are where
we want them anyway.
Also, in the process, fix a bug in fs.realpath on Windows.
If the user has permission to create symlinks, then use symlinks. If
not, then skip over all the tests that cannot be run using Junctions
instead.
Callbacks that were passed to the binding layer ran in the context of the
(internal) binding object. Make sure they run in the global context.
Before:
fs.symlink('a', 'b', function() {
console.log(this); // prints "{ oncomplete: [Function] }"
});
After:
fs.symlink('a', 'b', function() {
console.log(this); // prints "{ <global object> }"
});
In case a fd option is given to fs.createReadStream a read will instantly
happen. But in the edge case where fd point to an empty file and .pause()
was executed instantly, the end event would emit since no async wait was
between fs.createReadStream and the file read there emits end.
