Was it something like one of these error messages?

Google found me a way to list large objects... ``` git rev-list --objects --all \ | git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' \ | sed -n 's/^blob //p' \ | sort --numeric-sort --key=2 \ | cut -c 1-12,41- \ | $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest \ > ../list.txt ``` The largest file entry was... e0c5f0885bac 432KiB src/Roassal2/ RTRoassalExample.class.st That file is no longer in the repo, but... $ grep RTRoassalExample.class.st ../list.txt | wc -l ==> 158 and 158 * 432K ==> 68M Found the commit with that blob to examine... $ git log --all --pretty=format:%H -- src/Roassal2/RTRoassalExample.class.st | xargs -n1 -I% sh -c "git ls-tree % -- src/Roassal2/ RTRoassalExample.class.st | grep -q e0c5f0885bac && echo %" ==> a7753aef2a9f14cf5c84da83b8ebff7e4e35f0e9 $ git checkout a7753aef2a9f14cf5c84da83b8ebff7e4e35f0e9 $ vi src/Roassal2/RTRoassalExample.class.st and I see the culprit is icons being encoded directly in the class... { #category : #icons } RTRoassalExample >> exampleAligningGroupsIcon [ ^ 'iVBORw0KGgoAAAANSUhEUgAAAGQAAABkCAYAAABw4pVUAAAICElEQVR4XuWaWWhUVxjHI27Q 1oJttfjUusQHQdE+uIFUJYIVBC1VrDv6oKDUd5fGKK3RRgkRFfelaKvR1rpS7YbGFrUWcaHF msYsNMaJSWa9SWbmf3v+9/YmM5M7zj5J/P4wzGQyc+855/edbzuTo+vy1ZWUI38J5AORL/lA 5AORL/lA5AORL/lA5AORL/lA5AORL/lA5Es+EPlA5Es+EPlA5Es+EPlA5Es+EPlA5Es+EPmS D0Q+EPmSD0Q+EPmSD0Q+EPmSD0Q+EPmSD0S+5AORD0S+5AORD0S+5AORD6QratMmoLkZCH3v ...etc One way to reduce those historical file sizes would be running git-filter with an automated way to extract those icons to separate files and add code to load them. Seems hard. Following another path of investigation led me first to to "Git Compression of Blobs and Packfiles" https://gist.github.com/matthewmccullough/2695758 So trying... $ git gc --aggressive $ du -sh . ==> 18M https://stackoverflow.com/questions/28720151/git-gc-aggressive-vs-git-repack led me to the same job being done by... $ git repack -a -d -f --depth=10 --window=250 $ du -sh . ==> 18M My understanding is that this is safe and doesn't affect the commit history. However its just a local result. A few things I read gives the feeling that pushing from that repacked repo won't change anything on the server since it only sends a diff to the server, which then repacks in its own time. Perhaps the only way is ask GIthub Support if they can repack it. https://help.github.com/en/github/working-with-github-support/submitting-a-… cheers -ben

Was there some force push to Roassal?
by Cyril Ferlicot D. Nov. 10, 2019

Nov. 10, 2019

Hi, Since there is no release for roassal I have projects referencing a SHA of a stable Roassal 2 version. I see in my projects that the roassal SHA targeted was c1da8614c951008ea501f126ef3ccf25d73580ac but now I cannot find it in the history of roassal and my projects are failing. So I am wondering if someone forced pushed on Roassal 2? And if yes, what is the reason? Because of this, all the released of the projects depending on this version of roassal will never work again. Please, please, do not use destructive operations on projects that are intended to be used :( -- Cyril Ferlicot https://ferlicot.fr

https://jrmpc.ca/2019/11/07/green-light-for-jrmpc/ I'm on track to make this one of the greatest events in Smalltalk history! ;-) Yeah, I know, who gives a rat's ass about Canada? But there are ways to spin this that make it interesting for the rest of the world.

Script to download specific Pharo version
by BrunoBB Nov. 4, 2019

Nov. 4, 2019

Hi, We have a Linux script to build our image and was working well until recently. It seems that the failure is related (not confirmed yet) to https://github.com/pharo-project/pharo/issues/4764 Becuase it fail to load Seaside into the Pharo image. Is there any way to download a specific build or version like ? wget -q -O- https://get.pharo.org/64/703 | bash In this case to download Pharo 7.03 We want to try our script with different Pharo versions, because "wget -O- https://get.pharo.org/64 | bash" it download the latest. regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
