Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours:

http://lists.squeakfoundation.org/pipermail/packages/2015-July/008772.html

Name: Morphic-eem.990
Ancestors: Morphic-cmm.989

Update the CurvierMorph's drawCurvier preference
to the recommended style., eliminating the only send of addPreference:category:default:balloonHelp:
in trunk outside of Preferences.

=============================================

http://lists.squeakfoundation.org/pipermail/packages/2015-July/008773.html

Name: Kernel-eem.930
Ancestors: Kernel-eem.929

Fix the bug with the Debugger's through such that the Debugger would appear to freeze when encountering an MNU.  The example is Debug It on:

        Object flushDependents do: [ : e | ]

followed by Over, Through.  But in fact one can see the same issue doing Debug It and then Through on

        nil zork

What was happening is that Through was stepping through the uncaught and looping MNUs (of do: or zork in the above examples) since the Debugger did not catch unhandled errors during Through, and sicne doesNotUnderstand:'s default if uncaught is to resend.  The fix is merely to catch unhandled errors when doing Through to the same effect as runUntilErrorOrReturnFrom: caching errors for Over.

Also speed up Through.  The changes made in Kernel-eem.857 through Kernel-eem.896 to provide process-faithful debugging slowed down Process>>step a lot.  These changes restore the performance by using evaluate:onBehalfOf: once for each Through, rather than once for each step within Through.

=============================================

http://lists.squeakfoundation.org/pipermail/packages/2015-July/008774.html

Name: System-eem.750

System-eem.745 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.270

Rewrite Preferences to eliminate the AccessProtect.
Use a copy, update copy, assign scheme to update
the preferences dictionary atomically.

Change Preferences access method compilation to
use Object>>#value to eliminate a block creation.

Change Preference initialization to eliminate the
isKindOf: Symbol.

This is step 1.  Given SystemPreferences it is clear
that the preferences dictionary should be stored in
a class inst var, so that SystemPreferences and
Preferences can share methods but access different
dictionaries.  The dictionaryOfProferences[:] accessors
are dubious as they break encapsulatiopn.  For example,
the reportPreferences: method, which is the only external
access, could insateaqd be moved into Preferences class.

System-ul.748 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.270

- Iterate over pragmas once per method instead of once per pragma in Preferences class>>prefEvent:.
- There's no need to copy preferencesDictionary in Preferences class>>storePreferencesIn:, because it's a read-only data structure.
- Ensure the durability of the changes of preferencesDictionary in Preferences class>>atomicUpdatePreferences: by checking for changes before overwriting it.
