Re: [Pharo-users] OSProcess seems to fail on my macos

by Dimitris Chloupis

yes , git runs fine from command line. And yes I accepted the license. I use filetree and git from command line to work with that repo now without any issues.

Thanks. My medium-term plan is to run my Smalltalk app from a Pi - this was encouraging! -- View this message in context: http://forum.world.st/ANN-Working-with-Pharo-on-the-Raspberry-Pi-tp4857895p… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] VM crash on Ubuntu 14.04

by Johan Fabry

Ah those wonderful memory leaks â¦ :-/ I will try to narrow down the possible source, but that is not going to be easy â¦ Itâs really a very specific setup that always crashes on me, so It must be a freaky combination of factors that triggers the issue. Running a Roassal visualization certainly is needed to crash, but apparently itâs not the only thing. I will keep trying to remove elements from the setup to see what the required combination is. > On Oct 31, 2015, at 07:38, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > > not so badâ¦ that actually means that you are running out of heap, badly :P > and since I see a primitiveNativeCall there, most probably your (athens?) program is leaking somewhere. > > Esteban > >> On 30 Oct 2015, at 18:01, Johan Fabry <jfabry(a)dcc.uchile.cl <mailto:jfabry@dcc.uchile.cl>> wrote: >> >> >> More bad luck Iâm afraid.

Re: [Pharo-users] OSProcess seems to fail on my macos

by Johan Fabry

Hi, Did you try running the Xcode command line tools in a terminal? Sometimes when you do an upgrade you need to accept the license that pops up when you run these tools, and that causes this kind of issues. It happened to me a long time ago. > On Oct 30, 2015, at 18:14, Dimitris Chloupis <kilon.alios(a)gmail.com> wrote: > > I have several issues using gitfiletree, which in turn has issues with metacello trying to fetch git info about my git branch locally which I tracked back to OSProcess not executing on my macos. > > This started to happen as soon as I updated to latest XCODE and installed its latest command tools, anyone else with same issue ?

Re: [Pharo-users] fast subclassing/class creation in tests

Yesâ¦ I make a note here and have a look sometimes the next weeks. e) is really a problem: that both source-storage and change log is the same makes things complex (but of course for the time that it was done the solution is amazingly efficient) Marcus > On 29 Oct 2015, at 19:14, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > > yes, I already felt that test runs involving unlogged code generation is very slowâ¦ can you add an entry on the issue tracker? > > I can, but I am not sure for what. :) > > a) speed up regular class operations (class creation, removal, compilation) > b) speed up unlogged class ops > c) modify code generation tests in Pharo (ClassTest, possibly others) to use unlogged/suspendAllWhile > d) all of the above (as separate issues) > > plus bonus > e) create classes/methods without polluting the environment (.changes file) (because only removal is unlogged, not creation) (if this is even possible) > > Peter

Re: [Pharo-users] VM crash on Ubuntu 14.04

by Esteban Lorenzano

not so badâ¦ that actually means that you are running out of heap, badly :P and since I see a primitiveNativeCall there, most probably your (athens?) program is leaking somewhere.

OSProcess seems to fail on my macos

by Dimitris Chloupis

I have several issues using gitfiletree, which in turn has issues with metacello trying to fetch git info about my git branch locally which I tracked back to OSProcess not executing on my macos. This started to happen as soon as I updated to latest XCODE and installed its latest command tools, anyone else with same issue ? I tried several OSProcess commands but they all return empty strings even though they complete with no errors. An expert help would be of great assistance, thanks ! I have reverted back to using filetree and doing my git commits manually via command line.
