Re: [Pharo-dev] Pharo7 and full block closures
by Clément Bera
I totally agree with you on this.
For a while I had a CI job that was trying to execute Sista on the latest
version of Pharo and VM, and sent me a mail when something had gone wrong.
I disabled it when there was problems on the CI, I will make it work again.
This way I am notified and I can update the Sista code as Pharo 7 is
developed. That helps a lot.
On the Pharo CI the time to run tests matters hence I will try to find
another solution to test full block and the other bytecode set. I did not
do that because I hope I can change Pharo to use full block by default
soon, but since they're broken...

thank you for your response. I didn't expect it to work (after all you label it "Alpha" and I ran into issues already) but my intention for the mail was a bit different. Let me try to briefly explain my motivation. In my experience:
(1) Software not executed stops to work (or never "worked")
(2) The earlier breakage is detected the less expensive it is to fix.
My assumption is that Opal is part of Pharo and that we look at a regression of the Opal compiler and/or how it interacts with the rest of the image. As it might be easier to understand/fix it now than later I brought it up. From my point of view I wonder if we want to add ~50s to the CI process to execute:
CompilationContext bytecodeBackend: OpalEncoderForSistaV1.
CompilationContext usesFullBlockClosure: true.
OpalCompiler recompileAll.
Is there any value in doing so?
cheers

(2) The intuitive explanation is that the cost of analysis is a lot lower the earlier the problem is detected. There are fewer potential changes that lead to the breakage and the people involved will remember what/why they did reducing the cost of fixing. Ideally things are found to be broken and fixed before integration.
Maybe an analogy is old-school aviation navigation.. the earlier a mistake is found in navigation the closer to the original course...

yes, then you fetch and update⦠again, whatâs the problem? there is something Iâm missing about your reasoning :(

why?
you can compare branches inside same image⦠and even switch to them and reload. This will not work for pharo itself (because of initialisation order), but it will work on other projects.
one thing I want to add is a âreload on baseline orderâ option on baseline plugin⦠so you can update your system following a baseline.

Yes, so that makes pattern 2 practically impossible?
Where am I going wrong?
I create an image with a certain repo, checkout a branch.
6 months later I reopen the image and need to bring it up to date.
For that I need to look at a few other images, having different
versions/branches. I then need to create as many clones of the repo as I
have images I need to compare, open them, switch their repos to the
right clone and switch to the right branch and version.

btwâ¦
- metacello #lock function should work to âlockâ projects to other directions than url in baseline. I just donât know exactly how it works since I never did it myself.
- iceberg itself should not re-clone a project you already have in your registry. That means if you have project A who depends on project B, and you are working on a branch of B, if you load B first, iceberg will take that version instead the one declared in baseline (I made this at ESUG, because seaside development requires it).

yes you can.
shared repo is a suggestion, you can always chose to add a project from another place.

Re: [Pharo-dev] Pharo7 and full block closures
by Clément Bera
Hi Holger,
Nobody can guarantee any framework to be stable on Pharo alpha (Currently
Pharo 7) since deep changes can happen every day during alpha. So the
answer is yes, having any framework *not* working on the alpha version is
to be expected.
The instructions to use the Sista runtime are detailed here
<https://clementbera.wordpress.com/2017/07/19/sista-open-alpha-release/> in
the How to get/build a Sista image and VM section and are very clear in
step 1 about using Pharo 6 (the stable Pharo version). They also work with
Pharo 6.1.
Sista will work for the release of Pharo 7 as it did for Pharo 6 and 6.1
but it won't work every day during the alpha of Pharo 7 and no sane
framework developer can guarantee that. Sista does not work currently in
Pharo 7 due to some changes breaking the full block closures, I am going to
fix it but even then in the incoming months there is a high chance that
another change in Pharo 7 breaks it again, so I would never recommend to
use it with the alpha.

Pharo7 and full block closures
by Holger Freyther
Hi,
I kind of missed the open alpha of "Scorch" and to make up for it I tried to follow the instructions on Pharo7 but I do crash the VM. Is that to be expected?
"Add special selector for trap instruction"
Smalltalk specialObjectsArray at: 60 put: #trapTripped.
"Disable hot spot detection (to load the Scorch code)"
Smalltalk specialObjectsArray at: 59 put: nil.
"Recompile the fetch mourner primitive which has strange side-effect with alternate bytecode set and closures"
WeakArray class compile: 'primitiveFetchMourner ^ nil' classified: #patch.
"Enable FullBlockClosure and alternate bytecode set"
CompilationContext bytecodeBackend: OpalEncoderForSistaV1.
CompilationContext usesFullBlockClosure: true.
OpalCompiler recompileAll.
If I only execute the last three lines it is crashing as well but at a different point in the VM?
