Ehm, all the pharo builds are failing. Is this my fault?

Concerning Pharo, you did not break anything. External libraries are precompiled on the CI in some cache. When version number of those libraries are update, the cache is not automatically cleared. Therefore, the failure is postponed until the cache is cleared, which happens on a regular schedule apparently.

Concerning sq, we did not want to change each and every prefix to osvm when we switched squeak vm to osvm. It would have touched each and every file and the VMMaker and all plugin repositories, for not much added value. Who knows how many regressions could have been un-noticed. So do not consider sq* as Squeak only.

Concerning DND, it's beyond my skill, I've never studied its logic nor particular sequence of events. What you say sounds logical, and consistent VM behavior is desirable though. So if you say that you compiled, used the VM and saw no regression in an official release (say drop a .png in Squeak 5.3), I can do the merge (and squash).

Ideally we should do it on an old version of pharo too (7?), but at one moment, pharo people shall help us to help them, and this is not the trend. The INRIA team forked, and when I request community help on Opensmalltalk-vm-dev ML, I ear nothing but a big silence, I guess no one is interested. Newspeak sounds less like a problem, because they use their own form of FFI for windows system integration rather than plugin.

Thank you for the detailed explanations, @nicolas-cellier-aka-nice!

Yes, I confirm that.

What is about Cuis?

consistent VM behavior is desirable though

Hm, please don't merge yet. I just found further small inconsistencies in this implementation I would like to fix within this PR. I will update the description when I am done and mention you again. :-)

@codefrau This is very interesting to hear! For starters, my goal is to translate every incoming drag into a transfer morph that can be handled natively by any morph. However, reviving the full potential of DnD will be a very interesting follow-up project. If you have further information on how this could break all without anyone noticing, please tell me. :-) Do you know whether all platforms already supported this?

Which VM version is that? On Windows, DnD works as well as in the latest OSVM. Unfortunately, I cannot find a 64 bit version for Linux, so I cannot test Etoys To Go on Linux ...

@tom95 The message only I'm seeing is: ```terminal $ ./etoys.sh ./etoys.sh: line 107: ./Contents/Linux-i686/etoys: cannot execute binary file: Exec format error ``` `ldd` gives me `not a dynamic executable`. Does native Linux support more backward compatibility in terms of architecture than a virtualized Linux? I am using Ubuntu in Windows Subsystem for Linux.

@tom95 Great to know that WSL2 supports this. I still have to set up this, thank you :)

Thanks for all the hints, I will try that soon! However, reviving the full DnD potential will surely happen in separate threads and PRs. This one is ready now, again, at least from my side. Please see the updated description above. I hereby confirm that the latest version again does not show any regressions in an up to date Squeak image. @nicolas-cellier-aka-nice Would you mind to review/squash-merge again as soon as the checks have completed? :-)

I tested compiling this branch 'sqUnixXdnd' on Solaris;

the sqUnixXdnd code seems to compiles but how can I test please ?

In order to compile I have to apply a small patch, but that is always the case. (see PR #496)

It is an interesting topic, to hear and read about the history of the Unix VM and X11 support, which obviously is very much relevant to Solaris.

However when you write "this does not show any regressions in an up to date Squeak image",

what exactly did you test please ?

Currently it seems I can drag a file into Squeak, and this creates as PluggableSystemWindow object.

I don't seem to be able to drag anything out of Squeak.

Hi David,

thanks for your interest and sorry for the delay, I was on holiday!

what exactly did you test please ?

As you wrote, you can drag a file into the image and an external drop handler will handle it (or a dialog window will appear if there are multiple handlers). You can also drag multiple files into the image and they will be processed sequentially. So this is the only "acceptance test" I did so far.

From a lower-level perspective, you can manipulate `HandMorph >> #generateDropFilesEvent:` and insert a `Transcript showln: {dragType. numFiles}.` somewhere to watch the exact events generated by the VM. This PR removes duplicate/wrong events from the recorded list. You can also make sure that the following works:

- drag a file over the image, but do not drop it, then drag it away - does the image still work? - after that, drag another file into the image and drop it - is the correct file displayed? - try to drag some text into the image - this attempt should be rejected but the image should still accept other files after that

But essentially I wonder (from the discussion) so far, what you are trying, to change with this dnd PR and how I could try to test it.

In the first step, I only cleaned up the list of DND events generated by the X11 OSVM as described in the PR message. Depending on this PR, I am extending `#generateDropFilesEvent:` to also process the `DragMove` and `DragLeave` events. This allows it not only to drag files into the world itself but wrap them into a Squeak-like TransferMorph that can be dropped into morph or tool by reusing the existing `#acceptDroppingMorph:` interface. For example, you can drop a file directly into the Workspace without any other modifications. Marcel's idea! :-)

I don't seem to be able to drag anything out of Squeak.

That's right, it might have worked on some platform in some ancient past, but nowadays it does not appear to work. But this would be interesting next steps, as well as dragging non-file stuff such as text or images into the image. Stay tuned! :-)

Best, Christoph

Hi,

I tested the following, with a VM compiled from the sqUnixXdnd branch:

# git remote -v origin https://github.com/LinqLover/opensmalltalk-vm.git (fetch) origin https://github.com/LinqLover/opensmalltalk-vm.git (push) # git branch Cog * sqUnixXdnd

Tested:

1. drag a file over the image, but do not drop it, then drag it away - does the image still work?

Yes it works , the cursor temporarily changes to a 'drag with +' sign when, I drag the file1 over the VM display, and drag it away (without drop), and the Squeak VM continues to function.

2. after that, drag another file into the image and drop it - is the correct file displayed?

Yes, I think so. I have files file1 and file2 and first drag file1 without drop, and then I drag file2, when I drop file2 it displays the file2 path.

3. try to drag some text into the image - this attempt should be rejected but the image should still accept other files after that

The cursor changes again to a drag with "+" sign but when I drop the text, which I drag out of an external text editor, nothing seems to happen in Squeak.

The image continues to accept other files after that.

What also seems to work for me is to drag a folder (directory) into Squeak. I get some sort of Unix file browser for the files/directories in that folder (in Squeak).

I think it is an interesting PR (pull request).

But basically I don't understand what you are trying to fix.

But obviously there must exist bugs in there ...

However basically you seem to be "cleaning up" while I don't understand what effective bug you are trying to fix.

By the way I did the same 3 tests with a VM which I compiled from the OpenSmalltalk Cog branch (not from the PR).

I seem to be having the same results.

First of all, sorry if you receive this multiple times, most likely this is because I click the "Comment" button multiple times.

OK, I modified the HandMorph -> private events -> generateDropFilesEvent: as you indicated, from the Squeak6.0alpha-19793-64bit.image for the tests.

I also tried with Squeak 4, I have the same result when I try with the Squeak4.6-15012 (Squeak 4 VM).

When I drag and drop a file "myfile" into the Squeak window, the Transcript shows:

1 2 2 ... 2 2 3 4 3

and the object for "myfile" is created.

If I drag "myfile" into the Squeak window and then out of it (without drop):

1 2 2 ... 2 2 3

On the other hand if I use the VM, with this pull request, compiled :

First when drag and drop "myfile" :

1 2 2 ... 2 2 4

Then when dragging "myfile" without drop :

1 2 2 ... 2 2 3

So this confirms what you described ...

However to really test this pull request I think it is required to test the code (changeset) which you are planning to put into the "inbox".

Maybe I missed something but in the description of this pull request, you could give a pointer to the changeset you are developing.

Maybe if I can download it from some place, I can test it.

I now realise that you are actually talking about a combination of 2 things.

1. a change in the VM 2. a changeset of some Squeak code that depends on that the VM change

Correct ?

If so, I'd certainly would be interested in trying out the changeset.

Hi,

I'm just commenting on this out of interest, I cannot say anything on whether this PR is going to be merged, as I have nothing to do with that.

As far as I can see this looks a reasonable change, but we don't know, how the original author(s) think about it, whether they had a reason for their implementation.

But the context of your work is a little bit clearer now to me.

Basically you have dropFiles-examples.13.cs dropFiles3.14.cs changesets.

In my image I can "fileIn" those changesets by Tools->FileList and then clicking "fileIn".

My understanding is now that you need some VM changes/support for the dropFiles3.14.cs changeset, i.e. the underlying VM has some behavior, that you want to change for the dropFiles changes.

If it's useful I can do further testing on this X11 platform, as from what I understand this change is relevant to the Solaris X11 support.

For the moment - this may be a Solaris specific problem - when I test, drag and drop after fileIn of the dropFiles changeset I get the following, in a debugger:

- --- The full stack --- FileDirectory class>>requestDropDirectory: [] in HandMorph>>collectDropFilesAndDirectories: Interval>>collect: HandMorph>>collectDropFilesAndDirectories: HandMorph>>generateDropFilesEvent: HandMorph>>processEvents [] in WorldState>>doOneCycleNowFor: Array(SequenceableCollection)>>do: WorldState>>handsDo: WorldState>>doOneCycleNowFor: WorldState>>doOneCycleFor: PasteUpMorph>>doOneCycle [] in MorphicProject>>spawnNewProcess [] in FullBlockClosure(BlockClosure)>>newProcess

There may be Solaris specific issues with the FileDirectory I don't know.

David Stes

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

Hi,

I compiled the VM from your repository branch "sqUnixXdnd" (I applied one small patch the patch from PR #496 required on Solaris)

It's possible that there is some issue with the Solaris support, as this has not been used for a long time I think, and I'm only recently using it , but it's quite usable.

So when I use that VM and I use the Tools -> File List , I can "fileIn" the changesets that you posted.

Then after that when I drag a file "myfile" into the Squeak desktop, I get into a debugger.

When I right click on the debugger I can select "copy bug report to clipboard".

However it's possible that the changeset is using some functionality, that is somehow not working well on Solaris, so perhaps it can be independently tested (unrelated to the changes to the VM or the changeset for dropFile).

That's possible ...
