[BUG] SqueakMap not working in a new image.

Hello,

when opening the lates Trunk image, an old (I had this already a year ago) hit me:

One cannot open the  SqueakMap Browser.
Stack trace attached. (dnu: select:)

It used to be fixed by "SMSqueakMap bootStrap"
Yet, this produces another Stack Trace (dnu: do:)
It gets stuck when loding updates (

"Make sure map is updated"
map loadUpdates.

) in the Install-file.

I tracked it down to
        arrayOfRoots := self loadSegmentFrom: segment outPointers: outPointers.
in ImageSegment>>comeFullyUpOnReload: is returning nil, i.e., failing to load
the Image segment.
It seems, map.4718.sgz is no more compatible with trunk.

So Long,
        -Tobias

I think it is very important for SqueakMap to work in the trunk image.

SqueakMap is one of the greatest things ever for Squeak.  I see it as
a presentation tool, an opportunity for authors to provide, unlike
with Monticello, one-click installs of rich code AND content.

It supports SAR's, so dependencies are not needed.  The only thing
that's needed is a tool to help people build SAR files (which I've
done, by the way, MaSarPackage, on SqueakMap.

OTOH, I would like to know why we still have the Universe Browser
button still prominently on the desktop.  Isn't the menu accessible
enough, or is Universes the new standard for where 3.11 is going?

Universes also is dead.

See my proposal on http://wiki.squeak.org/squeak/6148

None should be in the image.

Hi Edgar, what about Monticello itself, should that be in the image?
If so, I'm interested to know why it should be included and not
SqueakMap.

To me, we should make an exception SqueakMap in the base image and
SMLoader should be in the core.

For just a few lines of code, a base / core image can be taken from
nothing to unlimited cosmos of possibilities without the user having
to, first thing, load the package-loading system.  In this case, don't
you think a few K of memory is worth that?

That is interesting. Does this work you mean:

SMSqueakMap default reload

...and it fails on the current map? What VM/OS are you on?

SMSqueakMap default reload works OK (map.3291.sgz).
Requesting an internet update (map.4719.sgz) does not work => Error
occured when updating map

I only have to click once on a button in my development image to release
muO as a sar archive, complete with all dependencies and external
documentation files and other resources. I can then add it to the
SqueakMap server within minutes.

I would hate to have to stop thinking about more interesting and musical
things just to fix what is not broken, only because SqueakMap becomes
deprecated.
