reject-osfile
=============
Rejects calls into ``OS.File`` and ``OS.Path``. This is configured as a warning.
You should use |IOUtils|_ and |PathUtils|_ respectively for new code. If
modifying old code, please consider swapping it in if possible; if this is
tricky please ensure a bug is on file.
.. |IOUtils| replace:: ``IOUtils``
.. _IOUtils: https://searchfox.org/mozilla-central/source/dom/chrome-webidl/IOUtils.webidl
.. |PathUtils| replace:: ``PathUtils``
.. _PathUtils: https://searchfox.org/mozilla-central/source/dom/chrome-webidl/PathUtils.webidl

* migrate both |compressFileContent| and |decompressFileContent| to this file
* format. For backwards-compatibility, |decompressFileContent| will however
* keep the ability to decompress files provided with older versions of
* |compressFileContent|.
*
* Compressed files have the following layout:
*
* | MAGIC_NUMBER (8 bytes) | content size (uint32_t, little endian) | content, as obtained from lz4_compress |
*
* @param {TypedArray|void*} buffer The buffer to write to the disk.
* @param {object=} options An object that may contain the following fields:
* - {number} bytes The number of bytes to read from |buffer|. If |buffer|
* is an |ArrayBuffer|, |bytes| defaults to |buffer.byteLength|. If
* |buffer| is a |void*|, |bytes| MUST be provided.
* @return {Uint8Array} An array of bytes suitable for being written to the

* corrupted. If your data is user-critical (e.g. preferences,

* detailed below. Note that no combination of options can be
* guaranteed to totally eliminate the risk of corruption.
*
* @param {string} path The path of the file to modify.
* @param {Typed Array | C pointer} buffer A buffer containing the bytes to write.
* @param {*=} options Optionally, an object determining the behavior
* of this function. This object may contain the following fields:
* - {number} bytes The number of bytes to write. If unspecified,
* |buffer.byteLength|. Required if |buffer| is a C pointer.
* - {string} tmpPath If |null| or unspecified, write all data directly
* to |path|. If specified, write all data to a temporary file called
* |tmpPath| and, once this write is complete, rename the file to
* replace |path|. Performing this additional operation is a little
* slower but also a little safer.
* - {bool} noOverwrite - If set, this function will fail if a file already
* exists at |path|.
* - {bool} flush - If |false| or unspecified, return immediately once the
* write is complete. If |true|, before writing, force the operating system
* to write its internal disk buffers to the disk. This is considerably slower
* (not just for the application but for the whole system) but also safer:
* if the system shuts down improperly (typically due to a kernel freeze
* or a power failure) or if the device is disconnected before the buffer
* is flushed, the file has more chances of not being corrupted.
* - {string} compression - If empty or unspecified, do not compress the file.
* If "lz4", compress the contents of the file atomically using lz4. For the
* time being, the container format is specific to Mozilla and cannot be read
* by means other than OS.File.read(..., { compression: "lz4"})
* - {string} backupTo - If specified, backup the destination file as |backupTo|.
* Note that this function renames the destination file before overwriting it.
* If the process or the operating system freezes or crashes
* during the short window between these operations,
* the destination file will have been moved to its backup.
*
* @return {number} The number of bytes actually written.

/**
* Verify that Scheduler.kill() interacts with other OS.File requests correctly,
* and that no requests are lost. This is relevant because on B2G we
* auto-kill the worker periodically, making it very possible for valid requests
* to be interleaved with the automatic kill().
*
* This test is being created with the fix for Bug 1125989 where `kill` queue
* management was found to be buggy. It is a glass-box test that explicitly
* re-creates the observed failure situation; it is not guaranteed to prevent
* all future regressions. The following is a detailed explanation of the test
* for your benefit if this test ever breaks or you are wondering what was the
* point of all this. You might want to skim the code below first.
*
* OS.File maintains a `queue` of operations to be performed. This queue is
* nominally implemented as a chain of promises. Every time a new job is
* OS.File.push()ed, it effectively becomes the new `queue` promise. (An
* extra promise is interposed with a rejection handler to avoid the rejection
* cascading, but that does not matter for our purposes.)
*
* The flaw in `kill` was that it would wait for the `queue` to complete before
* replacing `queue`. As a result, another OS.File operation could use `push`
* (by way of OS.File.post()) to also use .then() on the same `queue` promise.
* Accordingly, assuming that promise was not yet resolved (due to a pending
* OS.File request), when it was resolved, both the task scheduled in `kill`
* and in `post` would be triggered. Both of those tasks would run until
* encountering a call to worker.post().
*
* Re-creating this race is not entirely trivial because of the large number of
* promises used by the code causing control flow to repeatedly be deferred. In
* a slightly simpler world we could run the follwing in the same turn of the
* event loop and trigger the problem.
* - any OS.File request
* - Scheduler.kill()
* - any OS.File request
*
* However, we need the Scheduler.kill task to reach the point where it is
* waiting on the same `queue` that another task has been scheduled against.
* Since the `kill` task yields on the `killQueue` promise prior to yielding
* on `queue`, however, some turns of the event loop are required. Happily,
* for us, as discussed above, the problem triggers when we have two promises
* scheduled on the `queue`, so we can just wait to schedule the second OS.File
* request on the queue. (Note that because of the additional then() added to
* eat rejections, there is an important difference between the value of
* `queue` and the value returned by the first OS.File request.)
*/
