While I was working towards implementing
DosFileDirectory>>preferencesFolder & >>preferencesGeneralFolder
I was stepping through: SmalltalkImage>>snapshot:andQuit:
did a: <Restart>
and then stepped down to: Cursor write show
at which point the debugger hung the image.
Now I guess theres an equal chance this is not really an issue as
something "special" might be happening here straddling the save point.
Just thought I would report it for review.
To reproduce on non-Windows you could probably set preferencesFolder &
preferencesGeneralFolder on your platform to self shouldBeImplemented
and proceed from the debugger that comes up.
SmalltalkImage>>snapshot: save andQuit: quit
| snapshotResult resuming startupErrors |
Object flushDependents.
Object flushEvents.
self addSnapshotRecord: save andQuit: quit.
self processShutDownList: quit.
Cursor write show. <--------Image Hangs Here after a <Restart> of
the method while debugging following a resume..

One snag: I'm still getting strangely broken images (won't open
process browser or debugger) after trying to download some things. I
have mirrored squeak source, BUT, some things (SIXX, ODBC) don't
appear to have working configs, so I'm trying to grab the latest
packages, and *that* might not be mirrored. I might need to specify
the mirror server in my code to make them work.
Still, I don't get how simply asking MC to download something will
permanently mar the image w/o my doing an explicit save. Does MC
snapshot before/during an attempted load? It seems very misguided
that an innocent attempt to load something can hobble an image??
One other crazy possibility: is killing a vm from the (Ubunutu)
system monitor somehow not sufficient to clear what is running? Dumb
question? Maybe, but I'm stumped. Any ideas?

Subject: Re: [Pharo-project] 1.4 - better from Jenkins
I just downloaded the latest CogWin and Pharo 1.4 image and I got
"WARNING: Manufactured file handle detected!" at the bottom, and popup
full of startup errors.
A couple of days ago tried Pharo-1.4-14315 and with cogwin_r2522. I
had the same warning, with a debugger showing "Error: Got startup errors"
in method SmalltalkImage snapshot:andQuit: " at line:
startupErrors isEmpty
ifFalse: [ self error: 'Got startup errors ' ].
where startupErrors = an OrderedCollection(ShouldBeImplemented:
#preferencesFolder should have been implemented in DosFileDirectory
class)
So I thought I may as well try implementing
DosFileDirectory>>preferencesFolder - which I've left as a comment on
ISSUE 5255. <http://code.google.com/p/pharo/issues/detail?id=5255>
A nice side effect of this was that all the "WARNING: Manufactured
file handle detected!" went away. Reverting this change reintroduces
the warnings.
