Re: [josm-dev] how does the transition to tested work ?

Now if I upload a per-object upload and it fails partway the objects that were uploaded up until that point will be counted as uploaded and won't be re-uploaded. But like I said I don't know if this issue in particular was what was causing some of the duplicates I was seeing initially. Thanks for clearing this up.

Re: [josm-dev] Function to select or download a sequence of ways?
Hi Marko To the best of my knowlege there is no such function yet ... As a further development, it could be useful to create a selective download function (follow this way until reaching a branch or a given bounding box). ... except for this function which sounds like what the waydownloader plugin provides. Selection is a core thing. You can use it from plugins in three ways. (1) you can influence the current selection. See setSelected() on DataSet. Invoke it on the current data layer (Main.main.getEditLayer()) (2) you can get the current selection. See getSelected() on DataSet. Invoke it on the current data layer (Main.main.getEditLayer()) (3) you can listen to the current selection. See org.openstreetmap.josm.data.osm.event.SelectionEventManager Regards Karl Am 09.03.2010 10:07, schrieb Marko Mäkelä: Before I start reinventing the wheel in JOSM, I would like to know if there is a function or plugin that allows to select a non-branching sequence of ways. It would be nice if the selection function could optionally be restricted to the current selection, just like the search dialog, and if some predicates could be assigned to the ways, say, highway=tertiary or natural=coastline, so that any branches where the predicate does not hold would be ignored. With such a selection function, it would be easy to select the coastline of an area within a natural=coastline extract of the planet extract, or to select a section of highway or railway for defining a route relation, for instance. Last, some questions to help getting me started, in case this does not exist yet. Is the selection a core thing, or can this be done in a plugin? Where should I start looking first?

Re: [josm-dev] Painting
Jiri Klement wrote: One of the reason why painting appears slow is the fact that it's done in EDT thread. I think there should be special thread for painting. Disagreed (with both sentences). EDT will only send request to repaint and copy offscreen buffer to screen when it's ready. Painting thread will wait for repaint requests. When request arrives it will start painting immediately. If another request arrives during painting, it will wait. If there are multiple repaint request after painting is finished, only the last one will be processed. This is exactly what RepaintManager in Java does for you. User events (mouse gestures, ...) and posted tasks are processed and the repaint requests they caused are buffered and a repaint request is posted at the end of the event queue. Once the queue drains, the repaint happens, only once. If you think of coleascing paints across more user gestures (like continuous dragging), you'll face two problems: 1) the trade-off between UI responsivity and the amount of coalesced events. Too short delay before painting and you paint on every event anyway. Too long delay and the UI will feel slow most of the time. 2) Loss of feedback in the cases where the painting already takes considerable amount of time. Separate thread won't help you neither on multicores, as you'll keep the problem serialized. Everything else but painting is fast enough, so you'll have AWT thread idle happily waiting for next event while the painting thread will fully load one core. Well, there will be the benefit of having the rest of the UI responsive, but we're not here to solve multisecond painting of zoom-to-fit of large datasets this time, are we? As for the initial comment regarding full repaint just to do rubber-band: There's no problem with full repaint as long as you do it fast enough. And this is doable. Proved. Moreover, I fear the increased code complexity necessary for partial, maybe filtered, repaints may slow down the general painting so the net result will be worse. For the record, I've tried current JOSM and must say that the rendering speed improved a lot. What might help, IMO, is to disable painting plain points over given zoom level. JOSM already paints large datasets when zoomed in and slight simplification, when zoomed out can only improve the situation. (You don't need to see individual nodes when looking at half the Germany, do you?) Regards, Nenik ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
Re: [josm-dev] Plugins not working with 3094 and Linux ?

Perhaps it has been postponed by another month or two in the meantime. Plugins should probably wait to compile for Java 6 until the JOSM core is available for Java 6. I think it is quite clear: The final decision on the Java 6 switch will be made after the stabilization bugfixing phase.
