DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.

On a minor realization note, I realize that I will need to protect access to stuff based on class inheritance in a very reflective manner. I just thought that it could be abused by using lambdas and such, but an object method would be in the context of the original location it came from. That is the normal way things are accessed in Java. Reflective invocation will always be slower because it delves outside of the pre-compilation bounds and is done at runtime so it must be secure. Although, after the first lookup since all reflective calls are known, there can be a cache called in the context of. The initial setup will be slower however calls following would be fast. I would have to manage this stuff specially for each class instance, but not the object instance. This is because reflective property stuff (such as permitting calls) is done based on class access and not the actual instance of the object. So the class would get an attached "in the context of" which identifies the source class automatically (it is known by its own table), then of various remote targets. So this is essentially just a cache of remote calls being cached. It would have to be done correctly so that exploits using reflection could not be performed.

I made a class that just flags any IOException on a close(), I know it is a bad idea though. After cleaning up the hairball script which invokes roughbld to make hairball (eventually when I get to it) was using my old tool temporary directory that existed in other, so it should be rather out of tree now. I also thought of another idea as I write this blog for timeline purposes, if I even keep this up. build target instead of the old in-tree other temporary directory.}

Actually, that is the most descriptive commit message in recent times and the most longest. Will be writing the CacheHashMap now, although I really wish there were auto boxing and unboxing for SoftReferences. User supplied boxing, although possibly abusive could be very handy. Also will be making a bunch of changes to the main documentation. than previously before.}

Have not touched the new hash map code, just still touching up the documentation. Personally I will not do the commit line on every single commit just ones of real work done for them. I make many small commits since that is better than one giant commit.


Actually, I will use something I call an estimated time index or sorts to imply an estimate of the current time. Using commits would be neat but after only doing two, I can tell it will be rather difficult and mess with my work flow. So mostly just a small tag to show the estimated start time that I actually started writing. However it could extend for hours and hours, but it is all relative anyway.


I realized that it is actually a good idea to have unsynchronized collections and synchronized wrapper collections. There is added indirection, however a good enough compiler can remove that. The thoughts of how I am going to support extending off classes and interfaces in an implementation independent manner lingers in my mind. I could do some sort of hash based lookup when doing stuff with a random object.


Before I was going crazy and implementing all of Map but now I am only extending AbstractMap, just hope that it works out well enough. For now most of the SoftValueHashMap will remain in TODO until further work is needed for it.


Currently working on dependency walking so that package and class dependencies may be resolved. I also shortened HbStandardClassDep down to HbClassPathDep and matches the usage better.


Still working on it, will have to note to handle infinite recursion later to prevent it from happening by simply checking if it is already in the output list before going through the dependencies.


A thought has been lingering on my mind and that thought is that I must handle escaped Unicode characters in the source, luckily I have already written that for my older tokenizer I wrote.


Although others might not like it, using an Object oriented language so far has made things much easier. Mostly because it relies heavily on re-use of existing code to make things easier.


Thought about not supporting annotations in class files when decoding them but having annotations would be very helpful. I would have to split off the package parsing code, since that is virtually just annotations. Luckily the way I wrote it will only be slightly trivial to split off.


All of the annotation stuff is now moved over to TagParser which was nice, so now classes may use annotations just like packages. Also going to shorten the annotation keys to their shortest form to remove all the prefixed dots so that packages and classes are treated the same. There may be some conflict but the ones I am interested in are rather unique. This means that classes can now have build dependencies not specified in imports and such. This could be used to force a dependency in the case of reflection.


Since I added a base class for the parsers I can now have a simple method which handles dependency handling of both of these. Now also the info classes have it since dependency walking between the both of them is exactly the same.


Been fooling around for a bit rather than coding. What I need to do is work on the class parsing, but now I also realize that I've been using the pair for the dependency info. I can just use String here.
