<li>Cosmos.Debug.Common - new DebugInfo(xOutputFilename + ".mdf", true) - Takes
|

longer than Id like. But its SQL... not sure if we can do much. Maybe could do a

copy of raw file? Or is the problem SQL local startup time? If so would using

express solve this?</li>

</ul>

</li>
|

<li>ExtractMapFromElfFile - SQL is slow on inserts. Only store GUID labels. Add .asm

file position and when we need a label in between, parse just those parts of ASM
|

to get them. Also if we do this, probably dont need to store actual label name

<h3>
|
||||
Next Release + 1</h3>
|
||||
<ul>
|
||||
<li>Throw exception on null ref...</li>
|
||||
<li>Plugs - warn if plugging something that doesnt exists... caused the x08 bug?</li>
|
||||
</ul>
|
||||
<ul>
|
||||
<li>(joint with Kudzu) - Move all critical plugs out of old asms and remove building
|
||||
of old asms.<ul>
|
||||
<li>And the plugs also from CustomImplementations in IL2CPU?</li>
|
||||
</ul>
|
||||
</li>
|
||||
<li>Exceptions dont work. Try int.parse("asdf"). It runs but when the exception is
|
||||
hit we get garbage back instead. (ie exceptions through plug proxy dont work)</li>
|
||||
</ul>
|
||||
<ul>
|
||||
<li>IL2CPU.AlwaysCompile attribute and get rid of IDT.Dummy</li>
|
||||
<li>int j = Array.IndexOf(Digits, s[i]);<ul>
|
||||
<li>When Digits is a char array, we get a plug needed error.</li>
|
||||
</ul>
|
||||
</li>
|
||||
<li>cxdb contains full asm path and filenames over and over... cant we write them
|
||||
out once and use a byte/word index to identify them? This will make it smaller
|
||||
and make reading faster.</li>
|
||||
<li>Plugs
|
||||
<ul>
|
||||
<li>Source Plugs - Leave as they are</li>
|
||||
<li>Assembly Plugs - Change to have attribute on the TARGET instead of the
|
||||
implementation and only allow assembly.. this cuts out the "proxy" class and
|
||||
makes it easier to find plug impls. See Rings.html for more info. The assembly
|
||||
level plugs can even go in the same assembly, source file and if we can the same
|
||||
class? That is currently these assembly plugs require 3 classes to implement.
|
||||
its ugly and messy... we can get it down to 2 - 1 + assembly (X# only!). Current
|
||||
way is such a mess we even comment them as plugged, but then have to go guessing
|
||||
where the impl is... See example down below....</li>
|
||||
<li>Convert all source plugs and disable old attributes...so for new ones use new
|
||||
names</li>
|
||||
</ul>
|
||||
</li>
|
||||
<li>We need to dynamically
|
||||
load the plugs etc so we can just rebuild and run and even trace them without
|
||||
rerunnig the bat for each change</li>
|
||||
</li>
|
||||
</ul>
|
||||
<ul>
|
||||
<li>Ring attributes and enforcement<ul>
|
||||
<li>Also allow restriction of assembly references</li>
|
||||
<li>Only allow core to be /unsafe, no others</li>
|
||||
</ul>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>
|
||||
Even later</h3>
|
||||
<ul>
|
||||
<li>localloc - int.parse needs plug for now because of this.</li>

</li>

<li>UDP</li>
|

<li>TCP</li>

<li>Cosmos.Debug.Common - much in here is not common and should be moved to

VSDebug.. Add Readme.html that NASM and VSDebug use whats left</li>
