CI Hickups ...

by Torsten Bergmann

While our general build from Pharo 7 is (more or less often) green https://ci.inria.fr/pharo-ci-jenkins2/job/Test%20pending%20pull%20request%2… I've noticed more and more that the CI builds for the PR's to Pharo 7 even for trivial changes are often broken and not green https://github.com/pharo-project/pharo/pulls which is annoying and one still has the feeling to break the builds. As always I think getting a more stable CI is dependent on time, resources and priorities. But does anyone know if this is a general issue or something that is already worked on? Thx T.

Re: [Pharo-dev] Iceberg Loading issue

Hi Vincent, Every time I've seen this question asked, the answer has been to checkout the branch that you want and then "Reload All" from the list of packages.

Hi Myroslava, some infos: Â Initially for Squeak there was "eCompletion" written by Ruben Bakker.

Re: [Pharo-dev] How to get rid of empty XML nodes?

by monty

See #removeAllFormattingNodes and its comment in the latest version. And instances of SAXHandler and subclasses are meant to be created with #on: (or another "instance creation" message), _not #new_, otherwise they won't be properly initialized. The class comment is clear about this, but I should have overridden #new to raise an error like Stream does. Your misuse was helpful in bringing this to my attention, and I added a Stream-like #new implementation to SAXHandler. > Sent: Friday, December 08, 2017 at 9:21 AM > From: "Stephane Ducasse" <stepharo.self(a)gmail.com> > To: "Pharo Development List" <pharo-dev(a)lists.pharo.org> > Subject: Re: [Pharo-dev] How to get rid of empty XML nodes? > > Hi monty > > > On Fri, Dec 8, 2017 at 9:03 AM, monty <monty2(a)programmer.net> wrote: > > By "empty XML nodes," do you mean whitespace-only string nodes? > > Yes > > > Those are included because all in-element whitespace is assumed significant by the spec: https://www.w3.org/TR/xml/#sec-white-space > > I know.

Re: [Pharo-dev] Iceberg Loading issue

by Vincent BLONDEAU

Hi Max, Yes, I tried that too: pulling the branch outside Pharo, set it to the 21124 branch head, then launch Pharo and run the pull of incoming commits from Pharo. Also, loading one commit at the time works, but you cannot do it for a lot of commits, the list of commits is very slow to refresh (at least under Windows).
