With two runs of the following script... Smalltalk garbageCollect. Transcript open. "close after each run" [ Transcript crShow: ( [ | string | string := '-'. 1 to: 2000 do: [ :n | string := string , '-', n printString. Transcript show: string. ]. (Delay forMilliseconds: 10) wait. ]) timeToRun. ] forkAt: 41. Build 40162 reports timeToRun of 0:00:00:02.483 & 0:00:00:02.451 Build 40165 reports timeToRun of 0:00:00:00.037 & 0:00:00:00.099 Now I had meant to ask... I notice that FLFuelCommandLineHandler installs ThreadSafeTranscript, so I wonder it is affected by this change. Can some Fuel experts comment? Also I am looking for some advice for a minor downside I just noticed. The whole script above can complete between steps, so the entire output ends up in the PluggableTextMorph its size without being culled, which causes making a selection become really slow. Normally the excess text shown by Transcript is culled in half [1] by PluggableTextMorph>>appendEntry each time #changed: is called. PluggabletextMorph>>appendEntry "Append the text in the model's writeStream to the editable text. " textMorph asText size > model characterLimit ifTrue: "<---[0]" ["Knock off first half of text" self selectInvisiblyFrom: 1 to: textMorph asText size // 2. "<---[1]" self replaceSelectionWith: Text new]. self selectInvisiblyFrom: textMorph asText size + 1 to: textMorph asText size. self replaceSelectionWith: model contents asText. "<----[2]" self selectInvisiblyFrom: textMorph asText size + 1 to: textMorph asText size That works fine when #appendEntry is being called with lots of small changes, but for a single large change the entire change ends up in PluggableTextMorph via [2]. In this case model characterLimit "--> 20,000" [0] model contents size "--> 5,671,343" [2] where model == Transcript. So what is the behaviour you'd like to when too much is sent to Transcript? a. Show all content however briefly. b. Only the last 20,000 characters are put into the PluggableTextMorph, and the earlier data thrown away. I see a few ways to deal with this: 1. Limit the stream inside Transcript to a maximum 20,000 characters by basing it on some circular buffer. 2. Have "Transcript conents" return only the last 20,000 characters of its stream. 3. Limit to text sent to #replaceSelectionWith: [2] to 20,000 characters. Thoughts anyone? cheers -ben |

IMO 20,000 characters is way too little. I routinely set my limit to 200,000. So b) but with a higher limit. a) is pointlessly slow. In your implementation list, surely 2. is the only thing that makes sense? If the limit can remain soft then anyone that wants to see more simply raises their limit. 1. & 3. are implementation details left up to you. As long as the transcript is reasonably fast and has the same protocol as WriteStream (it needs to support printOn: and storeOn: et al) implement it as you will. BTW, the Squeak transcript is appallingly slow.

HI Ben
This is really cool that you spend time on it! Thanks thanks thanks! Really thanks! if you need a circularList I'm coding one for the systemLogger. Just ask. (I'm about to change the API of the new linked list I wrote (I never like the Link and ValueLink that we have in the system) but Link for a linkedList is as good as Cell (if I do not like Link :)) so I'm about to stop thinking that I prefer Cell and I will make sure that both classes use the same vocabulary as our ancient linkedList. :) May be I'm becoming wise after all :) Stef |

Hi Ben I tried to figure this out with Mariano. Apparently the Transcript parts come from an improvement that was suggested by Pavel Krivanek (see this issue: http://code.google.com/p/pharo/issues/detail?id=6428). The code presumably was tailored to the needs that Hazel (today called Seed http://smalltalkhub.com/#!/~Guille/Seed) had. We couldn’t find any other reason why we would do *anything* Transcript related, especially since the command line handlers print to stdout anyway. Mariano suggested I CC Ben and Guille, so I’m doing that. Maybe one of the two can shed some light on that method. From my point of view I don’t see why we should keep that part of the code. Cheers, Max

Well, I have no idea why that line is there :). It's old (so I do not remember), a tweak (read ´hack´) I probably did to make the bootstrap work at the time, and I don't think it's correct that line is there, so maybe we should remove it? :)

Thanks Eliot. Its good to know what is expected from Transcript.
I agree, (2.) would be efficient. It just would have been precluded if (a) was required.
Do you mean you'd like Transcript characterLimit to be a Preference ?
I can do (1.) with Steph's new circular list. Doing (2.) means (3.) wont be required for this, but its probably beneficial so I'll log it as separate Issue.

This would be useful to limit the size of the underlying stream if high priority thread should fill too much before the UI thread can clear it. Can you point me at it. Will I be able to do something like... stream := WriteSteam on: CircularList new. cheers -ben > > (I'm about to change the API of the new linked list I wrote (I never > like the Link and ValueLink that we have in the system) > but Link for a linkedList is as good as Cell (if I do not like Link > :)) so I'm about to stop thinking that I prefer Cell and I will make > sure that both classes use the > same vocabulary as our ancient linkedList. :) > May be I'm becoming wise after all :) > > Stef > > > |

I'm not sure. If it was a preference I'd use it, but few others may find it useful. As I say, I need at east 20,000 chars on the transcript to effectively develop Cog; the VM simulator produces lots of output and realistically a transcript is the only convenient place to view it. So whether it was a preference ofr not I'd make sure the limit was >= 20k.

I opened a case for removing ThreadSafeTranscript from the FLCommandlineHandler. Proposed slice is in inbox.
