[ANN] VM for Pharo 6.1 updated

Hello,

I backported stable VM from Pharo 7 to Pharo 6.1.
It should fix some issues (not listed, because I really don’t know them).

Let me know if something is wrong.

Cheers,
Esteban

Iceberg 1.0.0

Hi all,

Time for a new Iceberg update, that will be available in the next Pharo
build. This time, there are lots of cleanups and enhancements. On the big
highlights:

- Tonel migration plugin is available in the "Other menu item"
- Tests are green on 64 bits! (meaning iceberg can be safely used in 64
bits).

Thanks to everybody that participated in reviewing, opening/closing issues
or even fixing a typo!

Pharo got 10 years!

Hi

While browsing an old folder, I found the first commit of Pharo.

‘From Sapphire0.1 of 16 March 2008 [latest update: #10018] on 24 April 2008 at 10:22:48 pm’!
“Change Set: 00-classcleaning
Date: 24 April 2008
Author: stephane.ducasse
adding hasSharedPools instaed of sharedPools > 0″!
There is one import symbol in this first commit! It was about improving the system.
Pharo is a much better name 🙂 because it protects boats lost in the tempest and show the way!

[Ann] New iceberg videos!

Hi all,

This time (just before releasing a new version of iceberg) I wanted to share some videos with you. Feedback is welcome.

!! How to contribute to Iceberg
https://youtu.be/yGr5HvVWM0M

This video shows how to contribute to iceberg.
For this, you should update your iceberg installation and then just do a pull request.
This means that you need to start by forking
https://github.com/pharo-vcs/iceberg

- Path 1: Clone and pull (easy)
  - Clone your fork
  - Checkout the latest development branch (e.g., dev-0.7)
  - Pull from pharo-vcs/iceberg

  This path does not always work, as this is kind of self-brain surgery. Iceberg is updating itself. If this does not work, go to path 2

- Path 2: Install from scratch (if Path 1 does not work)
  - Use the script in the README file to unload and reinstall iceberg
  - Make sure you use the latest development branch in the Metacello script (e.g., dev-0.7)
  - Clone your fork and checkout the development branch

Once you have the correct version, you can load the tests by loading the development group of the baseline.


!! Basic Branching and Merging
https://youtu.be/c0IgIT2s6Js

This video shows in a simple example how to branch, merge and checkout different commits. In this video we first create a new class with a method, then we create another branch and force a conflict. We resolve the conflict during merge.

In the middle, bonus feature, we checked out a commit and stayed in
Detached HEAD for a while ;)

!! Loading a baseline from your repository
https://youtu.be/brUHEOr-p_E

This video shows how to load a baseline from Iceberg's UI.
We clone an existing project, see it is "Not loaded" and use Metacello plugin to load the default group.

Enjoy,
Guille

PS: Tomorrow I'll answer the threads about Iceberg that were going around
here in the mailing list. I was running today.

PharoContributor videos

Pharo contributor is a simple tool to help you contributing to Pharo.


https://github.com/astares/pharo-contributor

Call for new GC testers

Hi all.

We’ve been working on a GC with lower pause time recently and we are looking for people working with images over 2 Gb to tune it (Deployed applications, not interested in quick hacks). We can sign NDAs if required.

Companies and people helping us will be guaranteed that the GC about to be deployed will be fine-tuned for the use-cases they provided. To evaluate and tune it properly, we need three kind of use-cases (>2 Gb):

– an image growing from a small size to a large size

– an image performing random accesses on objects on a large heap

– an image decreasing memory

The best would be for us 3 DoIts performing the 3 examples with low dependencies aside from the image so we can reproduce easily.

[Ann] OSSubprocess 1.0.0

Hi all,

News from the OSSubprocess side. For those who do not know it, OSSubprocess is the library to call external processes from Pharo.

These are the main points of this release.

- 64bits support
- Issues Working on both Pharo 6 and 7
- Issue #34: Adding tests to validate that the return code is correctly handled
- Issue #27: Cleanup: remove OSSubprocess-Tests package
- PR #26: Add stress tests

This version works for Pharo >=6. Users of Pharo5 will need to stick with v0.2.5, because of non-compatible changes in uFFI (required mostly for 64 bits).

Additionally:
- We moved the repository to pharo-contribution to remove pressure from Mariano for releases and integrations
- We updated the configuration in the catalog
- We decided to move to a 1.0.0 versioning schema because 0.* does look like the library is not stable and it actually is (We have been using it in pillar and iceberg for quite some time).

You can load this version from the catalog or using with:

Metacello new
   baseline: 'OSSubprocess';
   repository: 'github://pharo-contributions/OSSubprocess:v1.0.0/repository';
   load.

Detailed changes log in
- https://github.com/pharo-contributions/OSSubprocess/releases/tag/v1.0.0
- https://github.com/pharo-contributions/OSSubprocess/compare/v0.2.5...v1.0.0

If you have any issues (or PR!), we wait for your issue entry in
https://github.com/pharo-contributions/OSSubprocess/issues

Have a nice weekend,
