P8 regression
by Hilaire July 24, 2019

July 24, 2019

Hi, We have been hit in DrGeo by another regression in Pharo8 (it is not present in DrGeo versions based on previous Pharo). When loading a Sketch with accentuated Latin characters (same occurs with Chinese but I have so far not enough information to assert it is the same error) there is a ZnInvalidUTF8 error. Attached Pharo8 See details https://bugs.launchpad.net/drgeo/+bug/1837745 For the record the stream passed to the XML parser (an old version but I don't think it is the problem) is from readStream message send to FileReference. Do you want a bug ticket? Hilaire -- Dr. Geo http://drgeo.eu

Save the date: October 22nd in Ghent for a Smalltalk WebCamp
by Johan Brichau July 24, 2019

July 24, 2019

Hi Seaside users, We are organising a Smalltalk WebCamp day in the Yesplan offices in Ghent on October 22nd. The idea originated in the Seaside channel of the Pharo discord group. However, itâs not supposed to be Seaside only. All Smalltalkers doing web development, possibly involving other technologies on top of Smalltalk, are encouraged to join. Letâs meet and exchange ideas. The topics are to be determined, following the idea of an unconference [1], except that, for practical reasons, we will ask you to confirm your attendance beforehand. More info to follow asap. Save the date and respond already to the group if you are interested to attend. Cheers Johan [1] https://en.wikipedia.org/wiki/Unconference <https://en.wikipedia.org/wiki/Unconference>

Transcript had a 1.25GB WriteStream - maybe a bug with clearing the Transcript?
by PAUL DEBRUICKER July 23, 2019

July 23, 2019

Hi - On Pharo 7.1 64bit mac mojave. My images grew to 1.4GB, so I ran ImageCleaner cleanUpForRelease. Smalltalk cleanUp. Smalltalk reportCPUAndRAM. to begin to track down why & I found that I had 1.3 GB of ByteStrings. (ByteString allInstances select:[:ea | ea size >1000]) sorted:[:a :c | a size > c size] gave me a list of 1174 strings. running self collect:[:ea | ea size] showed me that the first one in the list is 1245704483 characters long. And the next biggest one is 520714 (that one is the highchartsJS library stored in a MCMethodDefinition) John Brant's ReferenceFinder & the "Open pointers to" shows that the very long String is the collection of the Transcript's stream. The only thing that got rid of the big string was running Transcript initialize. 10 timesRepeat:[Smalltalk garbageCollect]. Then saving/closing/reopening the image. I had always assumed that when you delete the contents of the Transcript, by selecting everything in it and deleting it ,it was all deleted. Or when running Transcript clear Or one of the "clean up" methods like those above. Anyway. It seems like the stream should clear more often than it does (looks like it may never empty itself? I don't think there is code in the image that does that though. WriteStream>>#reset & WriteStream>>#close do not empty the #collection or #stepContents inst vars. And it doesn't look like there is a method to empty/re-initailze those inst vars defined in the Stream hierarchy in 7.1 or 8.0. I made an issue https://github.com/pharo-project/pharo/issues/4074

where are system settings stored?
by Dale Henrichs July 22, 2019

July 22, 2019

I am currently using Pharo 7.0 and I've just discovered that my "local directory" is /home/dhenrich/rogue/_homes/rogue/_home/dev/clients/gci_70_tst/pharo-local: This file has to date back to the beginning of the year and i had deleted that directory structure a week or so ago before starting on my (totally unrelated work) and didn't discover the problem until i tried to run an image created locally up on traivs[1], where this bug[2] manifested itself and I eventually tracked the source of problem to the "local directory" setting ... Now I would like to know where the pharo settings file is hiding, so that I can avoid running into this problem in the future ... ... I've poked around in the Settings Browser looking for the default location of the settings file. There's "Store Settings" and "Load Settings", but nothing that allows me to find out/control the location of the settings file itself ... ... I only got to this point by tracing back from allinstances of OmSessionStore to a class var where the "directory" was stored and then got the settings browser by looking at senders ... but now I've run out of ideas. I assume that this is common knowledge, but not quite common enough for me:) Thanks in advance for the help.

Playground auto-save?
by Hilaire July 22, 2019

July 22, 2019

Hi, I have to admit it is working randomly in P7 with Dr.Geo. (19.06 rel) Sometime script can be retrieved with the playpage button other time no: executed script can not be retrieved. Its behavior is not predictable and it is a problem for me and the kids playing code. Hilaire -- Dr. Geo http://drgeo.eu

.package directory tree
by ian July 22, 2019

July 22, 2019

All, Newbie Question: I filed out a whole package by right clicking on the system browser package name and got a directory structure similar to the following: packagename.package -> monicello meta -> categories.st -> initializer.st -> package -> version -> properties.json -> Class.class -> class -> some.st -> another.st -> instance -> some.st -> another.st -> methodProperties.json -> properties.json -> AnotherClass.class -> same as Class.class directory structure above Issue: How do I file this all back in? There seems no way to do this in any easy fassion. Trying to file the .st's by themselves creates dependancy nightmares. If I can file this out in one singe click does it not make sense that I should be able to do the reverse in on single click or am I manually forced to recreate all my code? Thanks!
