Hi cyrille I published a read to be tested version of UpdateStreamer. Please have a look this is in PharoTaskForces/Updater I'm a little class inspired heavily from Utilities that download update.list and launch update. you can tell me to update throw a given number of update or to be verbose. UpdateStreamer new beVerbose; updateFromServer This will update all the updates available and show up dialogs UpdateStreamer new beSilent; upToNumber: 13000; updateFromServer let me know if this is working. I tested it and it seems so. Once we are a bit more confident :), we can use it in pharo and nuke (yeah) Utilities. Stef

I am working on 1.0-beta.27.4 right now and you could end up with code that I am attempting to debug which could lead to unexpected results for you:) If you load in a version of OmniBrowser that is compatible with 1.2, before loading the Metacello UI that should work ... A safer course of action would be to do this...load the latest packages from OmniBrowser and then the latest _released_ version of Metacello: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOmniBrowser'; package: 'ConfigurationOfMetacello'; load. then: (ConfigurationOfOmniBrowser project version: '1.1-baseline') load. (ConfigurationOfMetacello project latestVersion) load: 'UI'. You'll get an OmniBrowser that runs in 1.2 and the OB-Metacello tools. I've tried this and it appears to work fine... Dale

Re: [Pharo-project] Linux vm default plugins directory

by Schwab,Wilhelm K

Bert, Eliot, FWIW, I have had terrible results with LD_LIBRARY_PATH on Ubuntu - maybe I'm just missing something. I probably should let the squeak script handle it, but it seems silly to use a script to call a script, so I've typically gone straight to the vm; that appears to be getting harder to do with time. About plugins not loading, my big point is that we should not have to guess about what is or is not happening. The vm does not provide enough information to reliably fix problems.

WebClient is a perfectly good external package and for the time being I prefer it should stay that way.

On both of these issues I feel very strongly; I will not make the code substantially worse only to deal with shortcomings of Pharo. So if you cannot come to a reasonable resolution for these, you'll need the extension methods.

Re: [Pharo-project] Serial ports on Linux

by Schwab,Wilhelm K

Markus, If you have some experience with serial I/O on Linux, I would appreciate your giving it a quick shakedown; if it is just plain broken or is still known to work, it would be nice to confirm either way. I would like to use the binary distribution, but it does not report enough of what it is trying to do (so no clues when things fail) and I end up hacking to add tracing with possible installation troubles as a result. That said, this time around, I find myself in serialPortOpenByName() and puzzled by the failure being allegedly detected by: /* save the old state */ if (tcgetattr(sp->spDescriptor, &sp->spTermios)) My question: is there old state to save on the first pass? errno is not helpful; it is set to 5 aka I/O error :( I find myself wondering whether this should be conditional on the internal state of the descriptor, and the failure to open simply being that it gives up too easily? Then again, it could be detecting a true error condition and preventing certain disaster in the lines that would follow. Any ideas? I can't get /dev/ttyS0 to open by name or number. 'COM1' worked nicely on Windows. Bill Markus Lampert markuslampert at yahoo.com Wed Sep 1 15:28:38 UTC 2010 Hi Bill, haven't used the serial interface with the new VMs (yet), but previously under Linux I had to use the vm option '-notimer'. I did not find any negative side effects with that option. Hope this helps, Markus

Re: [Pharo-project] Please help!! Error: There is no free space in this set!'

I am talking that it just raise that error. What I do particulary in SqueakDBX (it is optional thus) is that when a Connection is created, it is added to WeakRegistry default so that I can implement #finalize and this method releases the database connection if it was not already done. This is for possible bugs or developers where they don't cal correctly yhe#disconnect method. Of course, if you use the pool you won't have this problem (depending how many connections you define in the pool as max). Anyway, while running tests, I create a lot of connections, thus, I get the error "There is no free space in this set!'" when the code tries to add the connection to the WeakRegistry.
