Re: [Pharo-dev] A taste of bootstrap

by Mariano Martinez Peck

Hi Pavel, Congrats for your hard work! You know me well, so don't take my next question as negative. You have been working in minimal images since years. Guille has also done quite some work, and many other people as well. My question is.... have we decreased the effort to keep it working as Pharo evolves? Previously, there were always problems with the dependencies: a single commit to Pharo would add or break a dependency and so we cannot bootstrap anymore. In other words...there was still a lot of human action needed to check and fix dependencies. Is this still the case?

If you installed it with gitfiletree/remote git repo, then you can follow what you've just posted, because it's the same. However if you installed it via the github:// protocol (or it was automatically pulled in via some other project's BaselineOf or ConfigurationOf), then it's a bit of pain, because you can't just pull in another project with the same baseline (Metacello it thinks it's a different project). Luckily, you should be able to explicitly permit the conflict: Metacello new baseline: 'MyProject'; repository: 'gitfiletree://wherever'; onConflict: [:ex | ex allow ]; load We should be documenting these things somewhereâ¦ Peter

Bootstrapping Pharo must be a nightmare on elm street.

Re: [Pharo-dev] git feature request

by Dimitris Chloupis

First you open a bug report , then you do what Peter said and you attach your pull request to that bug report. Github will do most of this for you , the only tricky part is to add the remote so each time you do git pull you pull also from the original repo. Generally you should use as much as you can of the github GUI , it will make your life much easier. If all you want is provide a bug fix , pull requests are tailor made for such scenario. Is there a particular problem you have with this ?
