Re: [Pharo-users] Glamour: update presenter with new text

[Hilaire]

Thanks Doru, it works as a charm!

I don't think I could find it by myself, or I will have to become a
Glamour expert.

To make it perfect, there is still a fix needed for the DrGeo script
browser:

The class method 'scriptName' of each Dr. Geo script class returns a
string, it used in the browser (and other place) to list meaningfully
the script (and not use the generic class name).

Therefore, when the user edit this method, the script name listed in the
left panel should be updated accordingly. I edit the code as bellow:

scriptsIn: constructor

constructor fastList

title: 'Scripts' translated;

display: [ :organiser |  organiser ];

format: #scriptName.

*constructor  updateOn: MethodModified from: [ SystemAnnouncer
uniqueInstance ].*


It gives the expected behaviour. Is it the right way to do it?

Thanks

Hilaire

[Pharo-users] Creating the smallest server runtime footprint

[Tim Mackinnon]

Hi - buoyed by the success of a minimal image (thanks Pavel), I'm wondering if 
I can get even smaller.

There are lots of .so's in the vm which wouldn't make sense on a server once 
deployed - sound, maybe libgit ...

Is there a list of the essential ones, or tips on what I can strip out of the 
Linux deployment? I also recall that i can leave out .sources and .changes as 
well right?

Re: [Pharo-users] Creating the smallest server runtime footprint

[Tim Mackinnon]

Related to this question - in the Linux vm there are several .so files that 
have numerical extensions as well as the same named .so file. Are these merge 
conflicts or platform variations of the same files?

E.g.

libSDL2-2.0.so.0.4.1 & libSDL2-2.0.so & libSDL2.so 

Are all in there?

Great.

Actually, this is not really related to Glamour, but to how CompiledMethods are 
dealt with by the system. A CompiledMethod is immutable, so every time you 
change a method, a new CompiledMethod object gets created. So, if the browser 
shows CompiledMethods, you will always see the old version. This would have 
been the same without Glamour as well. That is why you need to show a 
RingMethodDefinition which only holds a reference made by the name of the 
method that is resolved dynamically.

constructor fastList creates a CompositePresentation that holds a 
ListPresentation. Think of a CompositePresentation as a morphic pane: it is a 
holder without much logic. The data you want to update is dealt with by 
ListPresentation. Thus, what you want to update is the list, not the whole 
composite.

scriptsIn: constructor
constructor fastList
title: 'Scripts' translated;
display: [ :organiser |  organiser ];
format: #scriptName;
updateOn: MethodModified from: [ SystemAnnouncer uniqueInstance 
].

Doru

[Pharo-users] VoyageMongo not working in Pharo 6?

[kmo]

I just had a quick tryout of VoyageMongo in Pharo 6 and
VOMongoRepository>>save:anObject fails because UUIDGenerator does not have
the method makeSeed.

UUIDGenerator >> makeSeed was present in pharo 5. It's not there in pharo 6.

I installed from the Catalog browser where VoyageMongo is listed as being OK
for pharo 6.

Re: [Pharo-users] Is there a 64bit minimal image for either 6.0 or 7.0?

[Guillermo Polito]

Two different things:

1) yes, the minimal image is indeed minimal. Actually, the minimal image is
around 20% of the full image. Two working directions that are looking for
active contributions are:
 - reduce that 20% so bootstrap times are smaller
 - modularise the other 80% so that we can easily load new stuff.
 About this last point, there are already there in the repository a
couple of metacello configurations made by Pavel that allow us to reload
the 80% into the 20% image. But we should modularise them because so far
they are too big.

2) About the second point. You should not need to recompile everything. In
the image there is the Undeclared mechanism that should rebind new classes
as soon as they are loaded. Can you provide more insight on the bug? Why do
you need to recompile?

Tx,
Guille

yes, this should not happen. 
can you share which version of VoyageMongo are you installing?

(is on ConfigurationOfVoyageMongo>>stable: method)

Re: [Pharo-users] Is there a 64bit minimal image for either 6.0 or 7.0?

[Tim Mackinnon]

Hi Guille - thanks for replying and giving me some insight into all of this.

I have managed to get something working but there are definitely some issues 
that may need a bug report?

As I initially mentioned - if I download the Linux 64bit VM (curl 
get.pharo.org/64/ | bash) and then use the minimal image suggested by Pavel 
(https://ci.inria.fr/pharo/job/Pharo-6.0-Update-Step-3.2-Minimal/lastSuccessfulBuild/artifact/Pharo-minimal-64.zip
 
)
 I immediately hit a problem:

This minimal image supports Metacello, and the ST command line handler - 
however it us unable to process a script like the following (which is 
attempting to load a local filetree git package)

Metacello new
repository: 'filetree://../src';
baseline: 'Lambda';
load.

It fails because Metacello wants to use STON class>>readFromStream (in its 
#repositoryProperties method)- this minimal image does not contain STON (which 
is an error? Too much has been removed).

If I try to workaround this by loading STON as follows using the CONFIG command 
line handler:

./pharo Pharo.image config http://ss3.gemstone.com/ss/STON ConfigurationOfSton 
--install=stable —save

 this then highlights several other issues:

1) ConfigurationOfSton doesn’t have a group load will load it without Tests, 
and so loading it provides a series of errors due to TestCase not being in the 
min image (and there doesn’t appear to be a Configuration for loading SUnit by 
itelsf?) - I think this should be solved by either keeping STON in the image 
and/or having a config of Ston that loads without tests

2) Having loaded STON into that min image (albeit with broken Test cases), the 
minimal image doesn’t seem to use the Undeclared mechanism you describe and so 
the following classes (which have references to STON) - all need to be force 
recompiled like this:

{ MCFileTreeRepository. MCFileTreeStCypressReader. MCFileTreeAbstractReader } 
do: [:c | c compileAll ].

Otherwise I get an Undefined talkback when I try my metacello load, which I do 
using the ST command handler. 

Having dealt with 1 & 2, I am then able to run my Metacello load (as shown at 
the top). So it appears that there are a few related problems here.

I have a running example of this in Gitlab that demonstrates this - and can be 
used to replicate this problem if that helps (although the description is 
pretty clear I think).

Re: [Pharo-users] Seamless - send collections by value

[Denis Kudriashov]

Hi Petr.

There are few solutions to your problem.

1) You can specify #value strategy for any collections for your network
instance:


network transferByValue: (Kind of: Collection)

For your example you need to apply this strategy on server side. In that
case client will continue send collections by reference but it will receive
collections by value from server.

2) You can specify value strategy for BlockClosure. It will perform
#select: (for example) on server side without requests to client.

network transferByValue: (Instance of: BlockClosure)


Here you will need to apply strategy on client because blocks will be sent
from client to server.

3) You can explicitly pass objects with value strategy:

YourService>>getPersons

"on server side"

^retrievePersons asTransferredByValue


4) If persons collection is instance variable of other transferred by value
object then you can specify what value means for this container:

PersonContainer>>prepareValueTransferBy: aSeamlessObjectTransporter

aSeamlessObjectTransporter transferByValue: contents


5) You can ask any proxy to load local copy of remote object:

proxy asLocalObject.


Important notice:
- Seamless has no distributed garbage collection. So if you will transfer
by reference temporary objects they will be not collected as garbage. For
example server could  compute something and return it by reference. Nobody
will kill it.
But if you share only long lived service then it is not problem for you.
- there is no security in the level of Seamless. You should organize secure
channel by external tools like VPN.

These features are in todo.

Best regards,
Denis

[Pharo-users] Understanding DateTime and Locale and formatting times in a locale?

[Tim Mackinnon]

Hi - I’m really confused about DateAndTime support in Pharo?

If I have a server app running in the EU, and a user makes a request from 
Canada, and I want to format the time they see to be in their timezone - how do 
I do that with the classes in Pharo?

I can ask for a DataAndTime nowUTC, and if I know the user is in en-CA, I can 
create a Locale for them - but then how do I get the correct time offset, or 
how to I format that UTC date in their locale?

[Pharo-users] Pharacloud Seaside Rest exception when opening the application

[Lionel Akue]

Hello everyone,

I have a fully working Seaside MDL application in locale.

But when I load the image (pharo 6) to ephemeric cloud and try to open the
application, I get:

WAArgumentNotFoundError: argument "aPhonenumberString" was not found in
#(#arg1 #arg2)
Debug Full Stack

thisContext
WAFullPlaceholderPathMatch class(WAMatch class)>>argument:notFoundInd:
self
WAFullPlaceholderPathMatch

isZero ifTrue: [ ...etc...
self
WAFullPlaceholderPathMatch
thisContext
ByteString(SequenceableCollection)>>do:
self
'aPhonenumberString'

When I use an Pharo 5 image, the Seaside welcome page doesn't show up. And
I get a '500 internal server error'.

Could you help fixing this?

thanks,

Lionel

Re: [Pharo-users] Understanding DateTime and Locale and formatting times in a locale?

[Tim Mackinnon]

Thanks for chipping in - but its the other way around that I’m after.

I am looking at ZTimestamp now -but again I don’t quite get it?

ZTimestamp now gives me a timestamp in UTC (great) but how do I format it to 
show it in say Canadian time?

I thought it would be something like:

ZTimestamp now printOn: stream timezone: (ZTimezone id: 'America/Halifax’) but 
it doesn’t seem to be that?

I must be missing something.

[Pharo-users] [ANN] PharoLambda a demo of Pharo running on AWS Lambda

[Tim Mackinnon]

Hi - I’ve been playing around with getting Pharo to run well on AWS Lambda. 
It’s early days, but I though it might be interesting to share what I’ve 
learned so far.

Usage examples and code at https://gitlab.com/macta/PharoLambda 


With help from many of the folks here, I’ve been able to get a simple example 
to run in 500ms-1200ms with a minimal Pharo 6 image. You can easily try it out 
yourself. This seems slightly better than what the GoLang folks have been able 
to do.

Classic - the moment you write something, it suddenly dawns on you… its the 
other way around.

(ZTimezone id: 'America/Halifax’) gmtToLocal: ZTimestamp now…

They are the same files, typically sym-links.

Can you share a script to reproduce the steps to build a minimal image?

Is it reproducible under Windows?

Cheers,
