Collections-topa.565 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.160

When a stream is created on a collection, it tries to keep
using that collection instead of copying, even in the case
of mutation of the original collection.

The code removed prevented this.

Add a flush to WriteStream>>nextChunkPut:

This is a workaround for a bug in the runtime library of some versions of Ubuntu. The symptom is that creation of a class comment for a class that previously had no comment leads to a file size error in the new RemoteStream that points to the class comment. Actual file size and contents of the changes file are not affected by this bug, and the error occurs when reading contents of the changes file immediately following the initial save, Flushing the stream after writing a chunk to the changes file prevents the problem.

Let asUppercase and asLowercase use the unicode tables for wide strings/characters.

Avoid using #reciprocalFloorLog:
#reciprocalFloorLog: does the same as #floorLog: just with more noise.
Once upon a time it was required, but it is not anymore and should be deprecated.

Note that floorLog: already cumulates 3 rounding errors via (self ln / base ln)

(-1 to: (Float fminDenormalized floorLog: 10) + 1 by: -1)
        count: [:i |
                | pow |
                pow := 10 raisedTo: i.
                (pow asFloat floorLog: 10) < i and: [pow asFloat >= pow]].
89

But reciprocalFloorLog: is even worse:

(-1 to: (Float fminDenormalized floorLog: 10) + 1 by: -1)
        count: [:i |
                | pow |
                pow := 10 raisedTo: i.
                (pow asFloat reciprocalFloorLog: 10) < i and: [pow asFloat >= pow]].

Kernel-nice.843 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.160

Correct the bug I introduced for large integer sqrtFloor.

If receiver was of the form 2^2n*u
we did answer 2^n *E(sqrt(u))

But sqrt(u) = E(sqrt(u)) + residue
where 0<=residue&lt;1
And result is rather
        E(2^n*sqrt(u))
        = E( 2^n*(E(sqrt(u)) + residue))
        = 2^n*E(sqrt(u)) + E(2^n*residue)

As 2^n * residue can be big (superior to 1), we miss the correct value by default.

If we want to correct this, an approximation of residue is (u-E(sqrt(u))^2) / 2 E(sqrt(u))
This is more or less like super Newton-Raphson inner loop...
It would be possible to duplicate super work, but I feel like it's adding too much complexity for small reward, so I prefer to remove offending code for now

- #flush after printing error information, and before image immediately exits, otherwise it won't always get written.
- Add accessor for #negativeInfinity so I don't have to create new Float via Float infinity negated when all I want to do is compare.
- #asBytesDescription for Float too because this is a very useful printing method for even things other than byte counts (and we should think of a better name for it too).

(Issue http://bugs.squeak.org/view.php?id=7755)

Note that if other letters follow the s, then s is not interpreted as a scale, because it could be a message.
For example, (25sin) is interpreted as (25 sin) like in Pharo rather than (25s0 in) like in VW.
This way, the chances of ambiguous interpretation of existing code base is limited to the sole message #s.

Introduce an isAnExactFloat test, which is true when a Number can be converted as Float exactly.

Fix inconsistent image state as reported on squeak-dev:

Subject: [squeak-dev] Class subclasses
 
I think this is an old bug, presumably since ProtoObject was introduced (and presumably because ObjectTracer was used in the process).
 
If you ask Class for its subclasses (or if you inspect it) you see that ObjectTracer class is listed along with ProtoObject class, although ObjectTracer's superclass is ProtoObject. This can lead to some funny bugs if you try to write some hierarchy traversing code.

Make the debuggber process faithful.

"Process>>effectiveProcess is a mechanism to allow process-
faithful debugging. The debugger executes code on behalf of
processes, so unless some effort is made the identity of
Processor activeProcess is not correctly maintained when
debugging code. The debugger uses evaluate:onBehalfOf: to
assign the debugged process as the effectiveProcess of the
process executing the code, preserving process identity."
