Thanks guille and pablo for the explanation. One day we will have to work on a fuel solution for binary code loading.

Re: [Pharo-dev] Epicea: Revert the removal of a class

tinchodias wrote > However, I can say the Epicea changes browser is prepared > to this scenario because it delays its UI refresh some milliseconds after > a > change announcement happened. Can verify this really helps, having loaded large batches in a 6.1 image (with no other browsers open, for obvious reasons...) Though, it would be nice if the UI/change flushing updates were sent by signals to corresponding threads, instead of being forked off each time. That way, they doesn't clutter up a "start profiling all processes" with 5 - 20 ms entries for 999 different processes, so finding other slowdowns is less of a hassle... I assume its done the current way to avoid requiring explicit closing in order to not leak memory (running deferrer process referencing receiver, etc), but that can be avoided using a WeakMessageSend, see attached for example changes: OmDeferrerThreaded.cs <http://forum.world.st/file/n4958297/OmDeferrerThreaded.cs> Cheers, Henry -- View this message in context: http://forum.world.st/Epicea-Revert-the-removal-of-a-class-tp4957466p495829… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] Creating the smallest server runtime footprint

by Tim Mackinnon

Ah, I think Iâm starting to get closer to what I needâ¦ So if I want to load in that last piece to enable more general remote loading - how do I figure out how to do that? Iâm trying to work out where the build steps for building up the image (can I see them in Jenkins? It wasnât clear to me if I can look it up? Or the BaselineOfIDE was mentioned - looking there I can see a few metacello and gofer packages - but then I guess Iâm looking for an easy Mcz I can use with the example below? Or do I just load Metacello as a git submodule and then it will be on my local filesystem to then bootstrap up? I guess Iâm trying to work out the best sustainable approach to getting to a good server based image that has minimal tools and the ability to easily load remote code for pre-req projects.

OR is there something simple I can checkin and load locally to return that behaviour?

Thanks Denis for the fixes and new release. A pleasure to be using this browser.

The main point of my message was that I was able to do some successfull testing (as requested), and which version was tested. :-) Cheers, Alistair > I did some ad hoc testing with my current Pharo 7 code and it worked > without any problems.

I did some ad hoc testing with my current Pharo 7 code and it worked without any problems. (but this is only a small test) P.S. It would be great if the archive name included something that would allow us to easily guess which is a newer version, e.g. git rev-list --count HEAD Thanks, Alistair
