Browser's don't always refer to the **localStorage** feature by its actual name, either. For example, in
Chrome, the setting that enables/disables **localStorage** is hidden under "Advanced Settings" => "Privacy" =>
"Content Settings" => "Cookies" => "Allow local data to be set (recommended)". Which is a little misleading
and annoying, because **localStorage** != **cookie**.
"Content Settings" => "Cookies" => "Allow local data to be set (recommended)". Which is somewhat misleading

PCjs *never* sets any cookies. Cookies are bits of data that your browser saves and then automatically sends
off to the server every time you make a request. **localStorage** is nothing more than local storage. Granted,
a JavaScript application could certainly abuse it and send it around like a cookie, but PCjs doesn't do that.
The only exception is when PCjs detects a problem, and even then, you must first agree to submit your machine's

* Client/Server Disk I/O
*
*
* To support large disks without consuming large amounts of client-side memory, and to push
* client-side disk changes back the server, we need a DiskIO API that can be used in place of
* the DiskDump API.
*
*
* Use of the DiskIO API and any associated disk images must be tightly coupled to per-user
* storage and specific machine configurations, to prevent the disk images from being corrupted
* by inconsistent I/O operations. Our basic User API (userapi.js) already provides some
* per-user storage that we can use to get the design rolling.
*
*
* The DiskIO API must also provide the ability to create new (empty) hard disk images in per-user
* storage and automatically associate them with the machine configurations that requested them.
*
*
* Principles
* ---
* Originally, when the Disk class was given a disk image to load and mount, it would request the

* for larger disks -- let's just say anything stored on the server as an IMG file -- we'd prefer
* to interact with that disk using "On-Demand I/O". Any IMG file on the same server as the PCjs
* application should be a candidate for on-demand access.
*
*
* On-Demand I/O means that nothing is initially transferred from the server. As sectors are
* requested by the PCjs machine, PCjs requests them from the server, and maintains an MRU cache
* of sectors, periodically discarding the least-used clean sectors above a certain memory limit.
* Dirty sectors (ie, those that the PCjs machine has written to) must be periodically sent
* back to the server and then marked as clean, so that they can be discarded like any other
* sector.
*
*
* We also support "local" init-only disk images, which means that dirty sectors are never sent
* back to the server and are instead retained by the client for the lifetime of the app; such
* images are "read-only" as far as the server is concerned, but "read-write" as far as the client
* is concerned. Reloading/restarting an app with an "local" disk will return the disk to its
* initial state.
*
* initial state.
*
* Practice
* ---
* Let's first look at what we *already* do for the HDC component:
*
*
* 1) Creating new (empty) disk images
* 2) Pre-loading pre-built JSON-encoded disk images (converting them to JSON on the fly as needed)
*
*
* An example of #1 is in /configs/pc/machines/5160/cga/256kb/demo/machine.xml:
*
*
* <hdc id="hdcXT" drives='[{name:"10Mb Hard Disk",type:3}]'/>
*
*
* and an example of #2 is in /configs/pc/disks/fixed/win101.xml:
*
*
* <hdc id="hdcXT" drives='[{name:"10Mb Hard Disk",path:"/disks/pc/fixed/win101/10mb.json",type:3}]'/>
*
* The HDC component expects an array of drive entries. Array position determines drive numbering
* (the first entry is drive 0, the second is drive 1, etc), and each entry contains the following
* properties:
*
*
* 'name': user-friendly name for the disk, if any
* 'path': URL of the disk image, if any
* 'type': a drive type
*
*
* Of those properties, only 'type' is required, which provides an index into an HDC "Drive Type"
* table that determines disk geometry and therefore disk size. As we add support for larger disks and
* newer disk controllers, the 'type' parameter will be superseded by either a user-defined 'geometry'
* parameter that will define number of heads, cylinders, tracks, sectors per track, and (max) bytes per
* sector, or perhaps a generic 'size' parameter that leaves geometry choices to the HDC component,
* which will then pass those decisions on to the Disk component.
*
*
* We will enable on-demand I/O for a disk image with a new 'mode' parameter that looks like:
*
*
* 'mode': one of "local", "preload", "demandrw", "demandro"
*
*
* "preload" means the disk image will be completely preloaded, exactly as before; "demandrw" enables
* full on-demand I/O support; and "demandro" enables on-demand I/O for reads only (all writes are retained
* and never written back to the server).
*
*
* "ro" will be the fallback for "rw" unless TWO other important criteria are met: 1) the user has a
* private user key, and therefore per-user storage; and 2) the disk image 'path' contains an asterisk (*)
* that the server can internally remap to a directory in the user's storage; eg:
*
*
* 'path': <asterisk>/10mb.img (path components following the asterisk are optional)
*
*
* If the disk image does not already exist, it will be created (but not formatted).
*
*
* This preserves the promise that EVERYTHING a user does within a PCjs machine is private (ie, not
* visible to any other PCjs users). I don't want to be in the business of saving any user machine
* states or disk changes, but at least those operations are limited to users who have asked for (and
* received) a private user key.
*
*
* Another important consideration at this stage is dealing with multiple machines writing to the same
* disk image; even though we're limiting the "demandrw" mode to per-user images, a single user may still
* inadvertently start up multiple machines that refer to the same disk image.
*
*
* So, every PCjs machine needs to generate a unique token and include that token with every Disk I/O API
* operation, so that the server can revoke a previous machine's "rw" access to a disk image when a new
* machine requests "rw" access to the same disk image.
*
*
* From the client's perspective, revocation can be quietly dealt with by reverting to "demandro" mode;
* that client becomes stuck with all their dirty sectors until they can reclaim "rw" access, which should
* only happen if no intervening writes to the disk image on the server have occurred (if I bother allowing
* reclamation at all).
*
*
* The real challenge here is avoiding revocation of a machine that still has critical changes to commit,
* but since we can't even solve the problem of a user closing their browser at an inopportune time
* and potentially leaving a disk image in an inconsistent state, premature revocation is the least of
