Re: [Pharo-users] Configuring iceberg on Windows

[Andrei Stebakov]

I was trying debug it a little to see if how iceberg uses the path to
private and public keys. When I mangle the path to something non-existant I
got no error saying that the path is wrong. What would be a way to verify
that iceberg actually uses the keys?

[Pharo-users] Configuring iceberg on Windows

[Andrei Stebakov]

I followed the tutorial and provided IceCredentialProvider with ssh
settings, also put the same settings in Settings-Tools-Software
Configuration Management.
It seems not to have any effect since when I try to create a repo using SSH
it gives the error "Failed to connect to github.com".
I need to get past that error since I get it even when I install Moose via
Metacello.
Do I need to add ssh-agent as well? If yes, why do we need to provide
public/private key paths with IceCredentialProvider?

[Pharo-users] Secure socket timeouts on Windows

[Andrei Stebakov]

This issue has been bugging me for a while now, but I hesitated to post it
since I can't explain what's going on.
Every time I do any operation in Pharo related to secure socket connection
I have strange socket timeout even though I can connect to the URL using
web browser.
This time I was trying to install latest pharo 7.0 via pharo installer and
I got ZdcSecureSocketStream waitForDataFor: hang over trying to download
https://files.pharo.org/get-files/70/pharo-win-stable.zip
I can paste that link in Chrome and it can download it for me no problem
also I can download it using curl.

This issue only happens to me at work, when I do the same from home I don't
see this issue.
Anyway, I am at a loss here and wonder how can I debug and fix this issue.
Wondering if something like that happened for you guys.

Thanks, Kilon for such an insightful answer. Lots of stuff to think about.
I guess what I was waiting for is some success stories (which we already
have on the website), but coming from you guys as consultants saying
something like: "oh, this year I have more projects than last year" or "now

I know, it's hard to measure the success level in numbers (other than the
example you gave with github stats), more like the word of mouth kind of
thing.
Another metrix could be the subscription rate for this mailing list, since
chances are that most of new Pharo users would be on it and the
acceleration of that rate would definitely say something about Pharo
success. Wondering if we have access to that data.
Thanks for your insight!

Re: [Pharo-users] Microservices using Pharo

[Andrei Stebakov]

Thank you guys for your insiteful answers. I wish we could have some kind
of article summarizing those approaches so that next devs wouldn't have to
reinvent the wheel but start with some tried approach and maybe improve it.
As I only scratched the surface learning Pharo, I may have some naive
questions.
Does the fact (fact?) that Pharo uses green threads (not native os threads)
impact the performance?
With two Pharo images running in parallel on two core system, how does it
handle multiple requests at a time? There must always be some unblocked
thread waiting for connections and delegating requests to request handlers
in different green threads (using fork operation). Is my understanding
correct?
So even if one of those threads has to wait on a long IO operation (say
from DB2) that shouldn't impact the performance of other handlers?
I think that in most cases the CPU time for request processing is minal as
the bottleneck is in lengthy IO operations , DB waits and calling external
REST-ful services. So two images on two cores should be enough to handle
hundreds of simultaneous requests since most of the times the threads will
wait on external operations, not using the local CPU.
Please let me know if this summary that I got from this thread makes sense.
Yes, I fully agree that using docker pharo containers under some load
balancing is the way to go.

I guess for multiple images on the same server we need to spawn off images
listening on different ports.

What would be an example for load balancer for Pharo images? Can we run
multiple images on the same server or for the sake of balancing
configuration we can only run one image per server?

[Pharo-users] Microservices using Pharo

[Andrei Stebakov]

Does anyone use Pharo for Miro services? I heard about Seaside and Teapot,
just was wondering if Pharo can handle multiple simultaneous requests and
if it can, where it reaches the limit.

[Pharo-users] Some facts and figures about pharo gaining momentum?

[Andrei Stebakov]

Hi!

Do we as a community have some proofs in numbers that the popularity of
smalltalk grows?
I saw some articles that have some proofs that smalltalk is on the rise,
but for my presentation I'd like to back it up with some numbers if
possible.
You know, it's one thing when you preach to the choir but quite another
when you talk to some die-hard Java or JavaScript devs!
Any ideas about some great convincing material is also very welcome!

[Pharo-users] Nice catchy video for covering Pharo capability

[Andrei Stebakov]

Could you suggest a nice video for a presentation to showcase Pharo as a
nice language for data visualization?

Thanks,

[Pharo-users] Nice Pharo teaser in English?

[Andrei Stebakov]

I remember there used to be a nice Pharo teaser video at the top of
pharo.org which had some catchy images for data visualization etc.
Now all I can see is this link https://www.dailymotion.com/video/x3qedvo
and it's in French.
Could someone point me to the old teaser I am referring to?

Thanks!
Andrei

Re: [Pharo-users] [ANN] Iceberg v1.0.0

[Andrei Stebakov]

Hi Esteban

The reason I was asking how to update from 0.7.? is because if I take the
same script and execute it after plugging in the 1.0.1 version my Pharo
image freezes. I can try from a fresh Pharo 6.1 image and see if I get the
same problem.

Re: [Pharo-users] [ANN] Iceberg v1.0.0

[Andrei Stebakov]

On Pharo 7.0, Windows 10 when I try to clone from pillar-markup/pillar on
Windows 10, it gives me an error "the filename or extension is too long"
Also I got a couple of questions:
- How do I check the version of Iceberg
- How can I update from Iceberg 0.7.1 on Pharo 6.1 (installed using
instructions from https://github.com/pharo-vcs/iceberg) to latest Iceberg
1.0.1?

Thanks!
Andrei

Is there support for HTTPS on Windows (or any plans to get it to work)?

Re: [Pharo-users] Where do we go now ?

[Andrei Stebakov]

That would definitely help if Pharo shed some of its elitism with fancy
names.
Then it would have much more appeal for the masses (and definitely increase
popularity of Smalltalk) but it is the intent of the community, that's the
question.

[Pharo-users] Dynamic shapes for RTEdgeBuilder

[Andrei Stebakov]

If I want to select edge shape (solid vs dashed line) based on the property
of the "to" element, what technique can I use?
Currently it looks like #shape method of RTEdgeBuilder only allows to
specify a singe shape for all edges.

[Pharo-users] Quick way to switch from playground to system browser

[Andrei Stebakov]

I wonder if there is a best practice for modifying code in you class in
system browser and testing the behavior in the playground.
The way I do it, I have to type the code, use the mouse to find and switch
to the playground and then execute some code in it.
Is there a more ergonomic way to modify/test the new code?

[Pharo-users] Keeping packages up to date

[Andrei Stebakov]

I wonder if there is a generic solution to keeping certain Pharo project in
sync with development tree.
For example when I want to get latest Roassal I execute
Gofer it
smalltalkhubUser: 'ObjectProfile' project: 'Roassal2';
package: 'Roassal2';
package: 'Roassal2GT';
package: 'Trachel';
load.

Also I wouldn't know this unless the maintainers (thanks Alexandre!) of the
project told me what script to execute to get the latest version.
If I went to Project Catalog I can only get the stable version and if I go
and find Roassal2 it won't give me information how to get its latest
version.

How would I get info about how to update, say Roassal given the script
above from some Roassal project public page?
Talking about Roassal, if I go to
http://smalltalkhub.com/#!/~ObjectProfile/Roassal2/ page, it offers the
following script:
Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2';
configurationOf: 'Roassal2'; loadDevelopment

Which is probably not exactly equal to the script above (or is it?).

So, is there a generic way to get a latest version of some XYZ package?
What do I need to learn to be able to get that information about any Pharo
project (other than asking the community)? Something similar to "git pull"
when you know the repository.

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

[Andrei Stebakov]

Thanks, Alexandre
Looks like RTResizeableViewContextInteraction has no effect for the tree
that goes beyond the page.
On the other hand RTEmptyViewContextInteraction makes the tree that used to
be shrunk to fit in the page go beyond the page, as expected I guess.
So the RTResizeableViewContextInteraction doesn't work as expected (since
the expectation is to fit in the page as I understand)

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

[Andrei Stebakov]

Hi Alexandre

Thank you for your suggestion!
I also stumbled upon RTHorizontalTreeLayout that works much better in terms
of having more compact representation.
What I found out though is that when I inspect the view sometimes it
displays all the ellipses with their specified sizes and sometimes it
shrinks the view to fit in the viewable area. Can't put my finger on what
triggers the view be rendered with normal sized (doesn't fit the page) vs
zoomed out (fits the page)

[Pharo-users] RTLegendBuilder onDemand doesn't popup in html

[Andrei Stebakov]

Just wanted to report that when I add a legend to RTView, it works as
expected when I ispect the view.
When I export it to HTML, it shows the node, but neither mouse clicking nor
hovering bring up the popup.
Could you take a look?

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

[Andrei Stebakov]

Alexandre, is there a way to display RTTreeLayout so that it would try to
fit elements in a more vertical fashion.
Let's say even if the parent node has 8 children it would try to arrange
them not in one long horizontal line (which depending on the width of
elements can be really wide),
but spread them more vertically, so they would be viewable on one page.
Or maybe I need to try another layout to reach that goal?

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

[Andrei Stebakov]

Thanks, Alexandre, it works!
Also since I use RTView and RTEdgeBuilder I can use
view @ RTDraggableView to achieve the "draggability"

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

[Andrei Stebakov]

Hi Alexandre

I don't see how I can do without the scroll bars in HTML since the node
tree that I tender using RTTreeLayout has a big width and only 1/4 of it
fits in one page view.
Since I am building a web service I rely on rendering and serving the view
in HTML and without the scroll bars there is no way for me to view all
elements of the model in Chrome.

[Pharo-users] RTDoubleScrollBar is not rendered properly in html

[Andrei Stebakov]

When I do
v @ RTDoubleScrollBar.
and then export to HTML
the bars are rendered in the middle of HTML page and they don't actually
scroll.
I checked in in Chrome and IE on windows. Could you guys take a look?

Re: [Pharo-users] From Roassal RTView to html

[Andrei Stebakov]

Now it takes me to the right page, thanks!
One small glitch though, looks like after mouse click the UI element gets
grabbed by the mouse as if I pressed "click and hold".
So the only way to dis-engage the mouse from the element is to refresh the
html page.

Re: [Pharo-users] From Roassal RTView to html

[Andrei Stebakov]

Updated roassal via:
Gofer new smalltalkhubUser: 'ObjectProfile'
project: 'Roassal';
package: 'ConfigurationOfRoassal';
load.
(Smalltalk at: #ConfigurationOfRoassal) load

The problems is still the same: added ".html" suffix.

I'll try to find if there is a way to embed a clickable interaction.
Looks like since there is no response to the topic, I was wondering if it's
a non-pharo/roassal way to do it or it's just not so many people tried it.

[Pharo-users] From Roassal RTView to html

[Andrei Stebakov]

I was wondering if it's a good idea to expose some of the Roassal models
via web (say Seaside) using the ability of Roassal to generate HTML for the
view.
In this case how could I "spice up" the HTML making for example those
ellipces or lablels clickabe so the click could take me to some web page
bases on the data in the model?

How do you handle forked operations from TestCase point of view, when the
test expects a value to assert from an asynchronous operation?

[Pharo-users] Lengthy operations block UI

[Andrei Stebakov]

I have written some code that has a deep nested loop of calling
ZnClient>>get.
In the loop I also execute Transcript>>show but I can only see the
transcript output after a few seconds when the loop is finished. During all
that time while the loop is busy the UI is also unresponsive.
Is there a way to execute code in some sort of asynchronous way?

[Pharo-users] Unresponsive/frozen Gui

[Andrei Stebakov]

I experience that issue once in a while when I leave the pharo 6.1 on
windows and when I come back to it the UI is frozen.
Now I download pharo with moose image and it started to happen again (BTW I
couldn't install Moose in my pharo 6.1 using Metacello command)
I wonder if it's something that happens to many users and I have to get
used to it (ui freezes) or there ways to avoid it.
Again, maybe it's a windows specific problem and most of the pharo users
are either on Mac or Linux.

Re: [Pharo-users] Examples of Garage for DB2

I tried before to install odbc.
Gofer new
  squeaksource: 'ODBC';
  package: 'ConfigurationOfODBC'; load.
  (Smalltalk at: #ConfigurationOfODBC) load.

When I execute the code above I got an exception doesNotUnderstand:
#selector in RBParser>>externalFunctionDeclaration. Looks like currentScope
variable is not defined.
Also if I install ODBC from the catalog it also fails.
I still don't see how postgres can help but I'll give it another try.

Re: [Pharo-users] Examples of Garage for DB2

Pierce, I couldn't find any smalltalk framework to work with DB2 at this
point. I couldn't also find any Pharo odbc library. That's why at this
point I am looking for any ideas how to connect to DB2 from Pharo.

[Pharo-users] Examples of Garage for DB2

[Andrei Stebakov]

I need to be able to navigate DB2 connection.
As we discussed it a few days ago on the mailing list, the suggestion was
to use Garage.
I downloaded Garage to my Pharo 6.1 on windows. But in Garage I only see
drivers for MySql, Postgres and Sqlite3.
Does it mean that for DB2 I should look somewhere else or there is a way to
create a connection for DB2 using existing Garage functionality?
If there is a way, could you send some example?

Thanks!
Andrei

Pierce, I tried all of those "no display" options, the result is the same

Denis, I tried both. Running pharoconsole makes no difference. Same result
as running Pharo.exe

[Pharo-users] Running headless on Windows

[Andrei Stebakov]

When I run Pharo 6.1 with -- headless option on Windows, it executes the
eval command as expected but during the execution (which lasts 4 sec) it
opens the Pharo GUI.
Is it expected? I thought headless means that the whole execution would
happen in the background

Re: [Pharo-users] How to connect to DB2

[Andrei Stebakov]

Thank you for the answers! I thought ODBC was deprecated from Garage, I'll
give it another look.

[Pharo-users] Breakpoints in Pharo

[Andrei Stebakov]

Can I expect that break points in Pharo work in the same way as in Visual
Works?
When I set a break point in Pharo (6.1 on Windows), it displays a red dot
with an exclamation mark and when I send this message to an object, the
debugger doesn't get invoked.

Re: [Pharo-users] How to connect to DB2

[Andrei Stebakov]

Hi Stef

I already checked Garage, it doesn't have support for DB2. It used to have
support for odbc, but now it's deprecated.

Re: [Pharo-users] How to connect to DB2

[Andrei Stebakov]

Hi Stef

Gofer new
  squeaksource: 'ODBC';
  package: 'ConfigurationOfODBC'; load.
  (Smalltalk at: #ConfigurationOfODBC) load.

When I execute the code above I got an exception doesNotUnderstand:
#selector in RBParser>>externalFunctionDeclaration. Looks like currentScope
variable is not defined.
Also if I install ODBC from the catalog it also fails.

[Pharo-users] How to connect to DB2

[Andrei Stebakov]

Looks like ODBC is broken in Pharo 6.1.
What's the best way to get access to DB2 in Pharo?
