+// We have a feature where volumes can be locked when mounted. This
+// is used to prevent a volume from being shared with the PC while
+// it is actively being used (say for storing an update image)
+//
+// We use WakeLocks (a poor choice of name, but it does what we want)
+// from the PowerManagerService to determine when we're locked.
+// In particular we'll create a wakelock called volume-NAME-GENERATION
+// (where NAME is the volume name, and GENERATION is its generation
+// number), and if this wakelock is locked, then we'll prevent a volume
+// from being shared.
+//
+// Implementation Details:
+//
+// Since the AutoMounter can only control when something gets mounted
+// and not when it gets unmounted (for example: a user pulls the SDCard)
+// and because Volume and nsVolume data structures are maintained on
+// separate threads, we have the potential for some race conditions.
+// We eliminate the race conditions by introducing the concept of a
+// generation number. Every time a volume transitions to the Mounted
+// state, it gets assigned a new generation number. Whenever the state
+// of a Volume changes, we send the updated state and current generation
+// number to the main thread where it gets updated in the nsVolume.
+//
+// Since WakeLocks can only be queried from the main-thread, the
+// nsVolumeService looks for WakeLock status changes, and forwards
+// the results to the IOThread.
+//
+// If the Volume (IOThread) receives a volume update where the generation
+// number mismatches, then the update is simply ignored.
+//
+// When a Volume (IOThread) initially becomes mounted, we assume it to
+// be locked until we get our first update from nsVolume (MainThread).

+

+//        effect_command_t command;
+//    };
+
+
+// effect_interface_t: Effect control interface handle.
+// The effect_interface_t serves two purposes regarding the implementation of the effect engine:
+// - 1 it is the address of a pointer to an effect_interface_s structure where the functions
+// of the effect control API for a particular effect are located.
+// - 2 it is the address of the context of a particular effect instance.
+// A typical implementation in the effect library would define a structure as follows:
+// struct effect_module_s {
+//        const struct effect_interface_s *itfe;
+//        effect_config_t config;
+//        effect_context_t context;

+// type and return its address as effect_interface_t

+ Uploads will happen only when the file is one day old.
+ The purpose of these decisions is to have very simple rate-limiting
+ on the writes, as well as the uploads.
+
+ There is only one file active; it is either being used for writing,
+ or for uploading. If the file is ready for uploading, no further
+ writes will take place until this file has been uploaded.
+ This can mean writing might not take place for days until the uploaded
+ file is processed. This is correct by-design.
+
+ A notable limitation is that the upload is triggered by a location event,
+ this is used as an arbitrary and simple trigger. In future, there are
+ better events that can be used, such as detecting network activity.

+ * Signed integer types, yay team! A reminder on how two's complement actually
+ * works. The first bit is the signed bit, i.e. tells us whether or not the
+ * number should be positive or negative. If the two's complement value is
+ * positive, then we're done, as it's equivalent to the unsigned representation.
+ *
+ * Now if the number is positive, you're pretty much done, you can just leverage
+ * the unsigned translations and return those. Unfortunately, negative numbers
+ * aren't quite that straightforward.
+ *
+ * At first glance, one might be inclined to use the traditional formula to
+ * translate binary numbers between the positive and negative values in two's
+ * complement. (Though it doesn't quite work for the most negative value)
+ * Mainly:
+ *  - invert all the bits
+ *  - add one to the result
+ *
+ * Of course, this doesn't quite work in Javascript. Take for example the value
+ * of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of
+ * course, Javascript will do the following:
+ *
+ * > ~0xff80
+ * -65409
+ *
+ * Whoh there, Javascript, that's not quite right. But wait, according to
+ * Javascript that's perfectly correct. When Javascript ends up seeing the
+ * constant 0xff80, it has no notion that it is actually a signed number. It
+ * assumes that we've input the unsigned value 0xff80. Thus, when it does the
+ * binary negation, it casts it into a signed value, (positive 0xff80). Then
+ * when you perform binary negation on that, it turns it into a negative number.
+ *
+ * Instead, we're going to have to use the following general formula, that works
+ * in a rather Javascript friendly way. I'm glad we don't support this kind of
+ * weird numbering scheme in the kernel.
+ *
+ * (BIT-MAX - (unsigned)val + 1) * -1
+ *
+ * The astute observer, may think that this doesn't make sense for 8-bit numbers
+ * (really it isn't necessary for them). However, when you get 16-bit numbers,
+ * you do. Let's go back to our prior example and see how this will look:
+ *
+ * (0xffff - 0xff80 + 1) * -1
+ * (0x007f + 1) * -1

+ * We now move onto our friends in the signed number category. Unlike unsigned
+ * numbers, we're going to have to worry a bit more about how we put values into
+ * arrays. Since we are only worrying about signed 32-bit values, we're in
+ * slightly better shape. Unfortunately, we really can't do our favorite binary
+ * & in this system. It really seems to do the wrong thing. For example:
+ *
+ * > -32 & 0xff
+ * 224
+ *
+ * What's happening above is really: 0xe0 & 0xff = 0xe0. However, the results of
+ * this aren't treated as a signed number. Ultimately a bad thing.
+ *
+ * What we're going to want to do is basically create the unsigned equivalent of
+ * our representation and pass that off to the wuint* functions. To do that
+ * we're going to do the following:
+ *
+ *  - if the value is positive
+ *      we can pass it directly off to the equivalent wuint
+ *  - if the value is negative
+ *      we do the following computation:
+ *         mb + val + 1, where
+ *         mb   is the maximum unsigned value in that byte size
+ *         val  is the Javascript negative integer
+ *
+ *
+ * As a concrete value, take -128. In signed 16 bits this would be 0xff80. If
+ * you do out the computations:
+ *
+ * 0xffff - 128 + 1
+ * 0xffff - 127
+ * 0xff80
+ *
+ * You can then encode this value as the signed version. This is really rather
+ * hacky, but it should work and get the job done which is our goal here.

+--------------------------------
+
+Script A (ril_worker.js) runs global strict mode.
