You can try out previous versions to check. It could simply be that we
don't normally work with features this size?
Still we should assemble what we know into a bug report.

@Marco, nice catch, thanks.
I was able to arrive at the same out of memory issue (in the debugger,
following your instructions).
Solution? Hold on to previous geometry using a weak reference, and allow
the "undo command" to disable itself if the geometry is no longer available?
So you think that the freeze come from the OOM? That would be interesting.
Is this something that changed recently or did we just never notice? I can't
imagine that.
Ciao,
Andrea

I tested your workflow with 10m_admin_0_countries.shp from data_1_3.zip
testdata and, still, cannot reproduce the deadlock.
I tested it on the USA pacific coast area, near the boundary with Canada
and I successfully edited the horizontal boundary between the two states
(the line belonging to the USA polygon) many times, always cycling through
unselect polygon (cycling in the Pacific).
Just one silly doubt: to perform the test I am using the "Edit geometries"
Tool. Is it right? You did not specify this but it seems to me the only one
suitable for the task.

..but before sending it, I reverted to uDig for a "last look" and...
..whoop! It frozed!
In the picture you can(n't) see the Canada polygon on which I just
clicked.. ..so something happened AFTER the original polygon was removed and
BEFORE the higlighted one was drawn.
So I made this little test: I just started switching selection from Canada
to Alaska by clicking first on one polygon than on the ather and back
again.. ..keeping an eye on javaw.exe memoy print.
Here the result.
150mb : uDig Just started
168mb: new empty map created
205mb: 10m_admin_0_countries.shp added to map
260mb: click on Canada with "Edit Geometry" Tool
315mb: click on Alaska with "Edit Geometry" Tool
383mb: click back on Canada with "Edit Geometry" Tool
395mb: click back on Alaska with "Edit Geometry" Tool
432mb: click back on Canada with "Edit Geometry" Tool
441mb: click back on Alaska with "Edit Geometry" Tool
504mb: click back on Canada with "Edit Geometry" Tool
510mb: click back on Alaska with "Edit Geometry" Tool
514mb: click back on Canada with "Edit Geometry" Tool
514mb: click back on Alaska with "Edit Geometry" Tool -> uDig frozes!!
So my idea is that "highlighted" polygons objects get in memory an there
they get stacked.
This stuff never gets garbage collected.. ..so we might have some serious
memory leak problem here!
Also this might be the real cause of the issue: not actually anything to
do with editing itself.

Hi Marco,
could you please test with the uDig testdata set, which is how it happens
to me?
I am using the countries admin 10m layer.
Thanks,
Andrea
While using
on a Win 7 64bit machine
on the america_singlepart SHP, and doing the testing across the NORT
AMERICA - SOUTH AMERICA boundary (to involve switching between to large
polygons)
I could NOT reproduce the lock!
Marco
Hi Jody,
I tried to reproduce the deadlock Andrea reported while using a debugger
(in order to create my own better bug report). But was unable to catch it
out ...
Do you have any further tips for reproducing this Andrea?
I am afraid not... let's summarize:
- select USA polygon
- move a node
- unselect (click outside)
- select another polygon
- go back to the first
Here I already am in freeze. Try to do it more and more.
Is anyone else experiencing this deadlock?
Ciao,
Andrea
