I also prepared hooks and a backdoor script execution via web, so that we can investigate the image even if input is blocked. So next time this will happen, you can inspect and debug my image even from your machine :) Best regards Janko > > Stef > > On Oct 23, 2011, at 7:36 PM, Janko MivÅ¡ek wrote: > >> Hi guys, >> >> My 1.3 #13299 image is blocked again, but just UI not responding to any >> input events, while Aida web app server is running smoothly in backrgound. >> >> From Transcript I can see that last action was a new image backup >> procedure, which is done simply by : >> >> OSProcess waitForCommand: 'cp some.image some-bck.image'. >> >> This procedure is called from a background process and report to >> Transcript its start and end.

So, the best thing which you can do is to write error to log and quit. This is because startup manager knows what to start-up and in what order, but it doesn't knows, how critical a given service for properly running the whole image. Therefore, if you don't handle startup errors in your service code, a startup manager has no other choice , but just leave to OS. > Or what's the state of the email below? > > Andrea > > > Camillo Bruni schrieb: >> >> While working on Coral we encountered a rather annoying behavior of pharo >> images when starting up. >> >> We wanted to check if we can debug the CoralScriptLoader, but of corse >> since this happens at image startup time this is not a good ideaâ¦ HOWEVER we >> were no longer able to run the image as it immediately crashes during the >> startup. >> >> Now I wonder if it would make sense to add a couple of on:do: in >> SmalltalkImage >> snapshot:anQuit: to collect the errors of all the startup >> scripts and then only show them after all other startupListItems are >> processed. >> >> All in all the behavior would not much differ from what is going on right >> now, but would prevent stupid users like me from losing a whole image. >> >> camillo >> > > -- Best regards, Igor Stasenko.

Re: [Pharo-project] Marking methods

by Schwab,Wilhelm K

A long-standing wish-list item for me is the ability to apply multiple categories to any given method. From there, one could "borrow" Dolphin's idea of virtual categories and/or associating icons w/ categories. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Bernat Romagosa [tibabenfortlapalanca(a)gmail.com] Sent: Tuesday, October 25, 2011 5:18 AM To: An open mailing list to discuss any topics related to an open-source Smalltalk Subject: [Pharo-project] Marking methods Hi list, I've been thinking for a while that it'd be great if we could somehow graphically mark methods in the browser. Like adding an icon next to their name or highlighting them in different colors. When reviewing code, I find myself going through methods and would love to be able to mark them once they've been reviewed, to prevent me from going through them again. Does anyone else have the same needs? How do you guys manage this? I thought about flagging methods, but that'd mean I'd have to read through all my methods again to remove the flags once I'm done with the revision. Cheers, -- Bernat Romagosa.

[Pharo-project] Marking methods

by Torsten Bergmann

>you replace in the MethodDictionary, the original CompiledMethod >with a proxy Yes - OBBreakpoint uses this "object as methods trick" in its #install method. But what if already a proxy is installed (one for breakpoint) and you want to have another proxy ... BTW: Attached is a short MCZ to add an own OB command. Note that there is an extension to OBCommandBrowser to get it to work. You should see a 'Toggle ToDo' after installing it and opening a new browser in Pharo 1.3. This can help you to get started. bye T. -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

Re: [Pharo-project] Marking methods

Yes, I think you can reuse the idea of OBBreakpoint, which is using "objects as methods" (kind of proxies for method executions). That way you don't modify the original source, but instead you replace in the MethodDictionary, the original CompiledMethod with a proxy. You could create an abstract class OBMethodProxy or something like that, and then just subclass and say which literal to add (#halt, #todo, #revised, etc) Cheers On Tue, Oct 25, 2011 at 1:34 PM, Bernat Romagosa < tibabenfortlapalanca(a)gmail.com> wrote: > Thanks, I'll take a look at OBCmdBreakpoint :) > > > 2011/10/25 Torsten Bergmann <astares(a)gmx.de> > >> >The problem with flagging is that you are modifying the source code, I'd >> >prefer something provided by the IDE... >> >> Yes I know that it modifies the source code.

>The problem with flagging is that you are modifying the source code, I'd >prefer something provided by the IDE... Yes I know that it modifies the source code. It was more a pointer to how you can influence the icons. Currently AFAIK the IDE has no "to do list" - but you can implement one. You could provide an own OBCommand subclass to implement a "toggle TODO" command for the OmniBrowser. Look at "OBCmdBreakpoint" for an example. If you dont want to modify the source/keep the info on the methods itself you have to manage the todo list elsewhere - e.g. implement a ToDoList class with a default instance. Depending on the entries you can show a different icon, ...
