streamroller
============
node.js file streams that roll over when they reach a maximum size, or a date/time.
npm install streamroller
## usage
var rollers = require('streamroller');
var stream = new rollers.RollingFileStream('myfile', 1024, 3);
stream.write("stuff");
stream.end();
The streams behave the same as standard node.js streams, except that when certain conditions are met they will rename the current file to a backup and start writing to a new file.
### new RollingFileStream(filename [, maxSize, numBackups, options])
* `filename` (String)
* `maxSize` - the size in bytes to trigger a rollover, if not provided this defaults to MAX_SAFE_INTEGER and the stream will not roll.
* `numBackups` - the number of old files to keep
* `options` - Object
* `encoding` - defaults to 'utf8'
* `mode` - defaults to 0644
* `flags` - defaults to 'a'
* `compress` - (boolean) defaults to `false` - compress the backup files using gzip (files will have `.gz` extension).
This returns a `WritableStream`. When the current file being written to (given by `filename`) gets up to or larger than `maxSize`, then the current file will be renamed to `filename.1` and a new file will start being written to. Up to `numBackups` of old files are maintained, so if `numBackups` is 3 then there will be 4 files:
<pre>
filename
filename.1
filename.2
filename.3
</pre>
When filename size >= maxSize then:
<pre>
filename -> filename.1
filename.1 -> filename.2
filename.2 -> filename.3
filename.3 gets overwritten
filename is a new file
</pre>
### new DateRollingFileStream(filename, pattern, options)
* `filename` (String)
* `pattern` (String) - the date pattern to trigger rolling (see below)
* `options` - Object
* `encoding` - defaults to 'utf8'
* `mode` defaults to 0644
* `flags` defaults to 'a'
* `compress` - (boolean) compress the backup files, defaults to false
* `alwaysIncludePattern` - (boolean) extend the initial file with the pattern, defaults to false
This returns a `WritableStream`. When the current time, formatted as `pattern`, changes then the current file will be renamed to `filename.formattedDate` where `formattedDate` is the result of processing the date through the pattern, and a new file will begin to be written. Streamroller uses [date-format](http://github.com/nomiddlename/date-format) to format dates, and the `pattern` should use the date-format format. e.g. with a `pattern` of `"yyyy-MM-dd"`, and assuming today is August 29, 2013 then writing to the stream today will just write to `filename`. At midnight, `filename` will be renamed to `filename.2013-08-29` and a new `filename` will be created. If `options.alwaysIncludePattern` is true, then the initial file will be `filename.2013-08-29` and no renaming will occur at midnight, but a new file will be written to with the name `filename.2013-08-30`.

# readable-stream
***Node-core streams for userland***
[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
[![NPM](https://nodei.co/npm-dl/readable-stream.png&months=6&height=3)](https://nodei.co/npm/readable-stream/)
This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
