[Pharo-users] bug in debugger?

2016-09-28 Thread Usman Bhatti

Hello,

I have a strange error in my image that results in image start taking up
system memory and crashes when it attains the max. the VM can provide on my
machine (2Gb). I am working on Pharo 4.0 + Spec debugger.

After some digging in the image, I know that the error comes from an
assignment operation (below in bold). And the bug only occurs when the
method initialize is executed as inherited method.
The strange part is that that it does not crash when the value assigned is
slightly different e.g. "nosignature1" instead of "nosignature".

FAMIXInvocation>>initialize
super initialize.
sender := nil.
receiver := nil.
receiverSourceCode := nil.
*signature := 'nosignature'.*
candidates := FMMultiMultivalueLink on: self opposite: #incomingInvocations.

The crash doesn't happen when I override initialize in the subclass without
sending initialize message to the superclass. So this report is about a
very very specific case, but it is there. I tried to analyze further in the
debugger but with announcements, etc. I wasn't able to achieve anything.

So, if someone's interested to have a look, I can provide the image.

regards.

Usman

[Pharo-users] Spur problem?

2016-09-07 Thread Usman Bhatti

Hi,

While working on a Pharo 5 image for 3-4 hours, I got an image crash and I
was no more able to start the image from the UI interface. When starting
the image from the command line I got the following error:

Pharo(50871,0xa02c91a8) malloc: *** error for object 0x1af7a04: incorrect
checksum for freed object - object was probably modified after being freed.

*** set a breakpoint in malloc_error_break to debug

fish: '/Users/ubhatti/temp/vm-spur/Pha…' terminated by signal SIGBUS
(Misaligned address error).

The image is about 973 Mb (Moose + seaside + a model for a big industrial
software). This message might not go beyond reporting an error that I do
not know how to produce neither can I share the image (it contains client
proprietary software model and hence we are restricted).

Just to let you know that there was a problem and n ask if someone has
encountered it before?

In the versions prior to Pharo4, the directive showed me all the packages

Tx for looking.

I did:

Here is the difference in the output. And the first (with Pharo3) is much

hence one has to see the list of the individual configurations to

[Pharo-users] load directive

2015-09-10 Thread Usman Bhatti

Hi,

I'm trying to see packages loaded by Metacello. So, in the past, I used to
do:

(ConfigurationOfXXX project version: #stable) record loadDirective

to see the  list of packages resolved and loaded. But in Pharo 4.0, the
list of packages is empty.

How can I obtain the list of packages with the loadDirective?

tx in advance.
usman

P.S: I know GT-Inspector provides a map and a list of packages resolved
"statically". I'm looking to see how the loaded packages are resolved by
Metacello at "runtime".

[Pharo-users] customizing SystemWindow menu

[Pharo-users] Glamour: opening paths in tree with filters

2015-06-30 Thread Usman Bhatti

Hi,

I am having trouble with opening a specific path in tree presentation
(using MorphTreeMorph) when filtering nodes.

What I am trying to achieve is that if a node is searched in a tree at
level 4, all the parent nodes are opened to show the node searched (hence
the user the does not need to open the nodes manually).

In Glamour, when combined with filtering, expanding up to the root of the
search node works when the parent node is already expanded, otherwise the
nodes are not expanded. At the end of the mail, there are two snippets to
reproduce the behavior.

MorphTreeMorphaddMorphsTo: from: withExpandedItems: atLevel: is the
method responsible for this behavior in Glamour and it seems that nodes are
only expanded (to show their children) if they were expanded beforehand. Is
there a way to do otherwise in MorphTreeMorph (open paths with non-expanded
nodes)?

tx.

Usman

Code snippets in Glamour (Pharo 4.0):

| tabulator |
tabulator := GLMTabulator new column: [ :c | c row: #one ]; yourself.
tabulator transmit to: #one; andShow: [:a |
a tree
title: 'Show filter paths';
rootsExpanded;
children: [:item :x : level |
 (item  5 and: [ level  6 ])
ifTrue: [ {item + 1}]
ifFalse:[#() ]];
filterOn: [:text :each | text = each asString]].
tabulator openOn: (1 to: 1) searching for 3 does not open the path to 3
?!?!?!

| tabulator | tabulator := GLMTabulator new column: [ :c | c row: #one ];
yourself. tabulator transmit to: #one; andShow: [:a | a tree title: 'Show
filter paths'; rootsExpanded; children: [:item :x : level | (item  3 and:
[ level  5 ]) to stop adding infinite children ifTrue: [ level = 4 plug
a node 5 deep down and see if we can find the path ifTrue: [(1 to: 5)]
ifFalse: [ (1 to: item * 2) ] ] ifFalse:[#() ]]; filterOn: [:text :each |

[Pharo-users] case-insensitive regexp

2015-06-04 Thread Usman Bhatti

Hi,

Some regular expression engines include support for /i flag that makes the
regexp case-insensitive.

In Pharo, regexp matcher can be setup to be case-insensitive (e.g.
'mypattern' asRegexIgnoringCase). But once a matcher is setup as
case-senstive, can we provide a pattern to make its search case-insensitive
using the /i (or a similar flag) in Pharo?

regards.

On Thu, Jun 4, 2015 at 1:51 PM, Peter Uhnák i.uh...@gmail.com wrote:

 I do not think this is possible. The problem is that the Regex compiles
 (parses) the pattern so once it's created you would have to reparse it.
 Theoretically speaking you could add ignoreCase accessors to RxMatcher but
 it is likely it would break things; or add method to RxMatcher that would
 return a new RxMatcher object with the proper settings.

 Also note that regular expressions in Pharo are not the extended versions,
 where these things are usually available (alongside lookahead/lookbehind
 and other).
 And personally I find the Regex library so awkward to use that I always
 opt for PetitParser.

 
 myParser := 'hello' asParser.
 myParser matches: 'Hello'. false
 myParser caseInsensitive matches: 'Hello'. true
 

 on the other hand there is no option to turn it back again. So if you
 regularly need to switch it back and forth it wouldn't be solution either.

 A few easily fixed Type/pointers to Types mixups, and a slipup where two
 different classes are confused for the same aside, the real show stopper,
 if I haven't missed something entirely, is that the struct parser/NB in
 general does not handle const sized arrays*, which is used in a few of the
 required structs.

 Extending the parser should be relatively straight forward, along the
 lines of adding
 stream peek: #'[' ifTrue: [stream next.
type := SizedExternalArrayType type: type size: stream next.
stream next = #']' ifFalse: [self error: 'Missing closing bracket for

 to NBExtenralStructureFields  #parseFields:... after the name is read.

 Coding SizedExternalArrayType is a bit more work though...

 *The end goal would be to be able to generate accessors/read/write for a
 simple test-struct such as
 #fieldsDesc
 ^#(
   char   ip[MyClassVar +2];

 Yes, a parser for this would be great.

 I tried it with a little hack

 NBExternalStructure subclass: #Char_260 ...

 Char_260 class#fieldDesc
 ^ #(char data)

 Char_260 classinstanceSize
 ^ 260

 You need another accessor for accessing the data, otherwise you'll only
 get the first char. AND I don't know how
 the external memory is handle, probably it is never freed :)

 Now a complete example (attached code) call it with
 GetMacWin32 getMacAddress



 Code loads fine on my 3.0


same here.



 But hiccup on:


 resolveType: aTypeName
  a type name could be
  - a class variable name
 - a class name
 - a type name
 - a type name, followed by arbitrary number pointer chars - $*

 | name newName resolver binding ptrArity |
  newName := aTypeName.
 ptrArity := 0.
 resolve aliases and pointers
 [
 name := newName trimRight. --- HERE - as newName is a
 subclass of NBExternalStructure, so no trimRight
 newName := self aliasForType: name.
 newName last = $* ifTrue: [
 ptrArity := ptrArity + 1.
 newName := newName allButLast ].
 name = newName ] whileFalse.

 I changed to name := newName asString trimRight.


this worked for me.



 Call worked then but output gives this:

 GetMacWin32 getMacAddress 'BYTE_8 (
 data: $¼  -- some weird string here
 )'


It worked for me, I didn't encounter the problem of strange characters.
I get:
000c29ab7096
The last 4 trailing zeros are not the part of the mac address and I am not
sure why these are getting added. I'll have a look at your code.

thanks again.

 Now, we should all have a look at:

 But the plugins wont load because it requires the

 the VMMaker. Is there any recent config for VMMaker in Pharo because this
 one looks outdated:

I would like someone knowledgable to have a look at my nativeboost code
 because the nativeboost approach is more simple (everything's in the

Re: [Pharo-users] mac address on windows

2015-05-05 Thread Usman Bhatti

I succeeded to do it by encapsulating the C routine as a DLL and doing an
FFI call from my image (as suggested by Guille).

I also tried to perform the nativeboost call by creating my structures in
Pharo. The function in Windows that can be used to retrieve mac address in
Windows: GetAdaptersInfo
https://msdn.microsoft.com/en-us/library/windows/desktop/aa365917%28v=vs.85%29.aspx
that
accepts a PIP_ADAPTER_INFO
https://msdn.microsoft.com/en-us/library/windows/desktop/aa366062(v=vs.85).aspx
structure.
I subclassed NBExternalStructure to define this struct and the other used
by it in the image but my NB call returned with 87 code (Invalid parameter)
and it was impossible to debug. However, I would like to make this thing
work to understand what went wrong.

With ProcessWrapper, I could not load the classes essential for making the
plugin work.

[Pharo-users] mac address on windows

2015-05-02 Thread Usman Bhatti

Hello,

Has anyone tried to retrieve MAC address(es) of a windows machine using
Pharo? I have tried two options thus far without any success:

1/ OSProcess: I tried  (PipeableOSProcess command: 'ipconfig /all') output.
This opens a command prompt on windows machine without anything happening
inside it. Although when I try it on Linux/Mac (with ifconfig), I retrieve
the output of the command. Another option is to do OSProcess command:
'ipconfig' but I wasn't able to find a way to retrieve the output of the
command.

2/ Nativeboost comes with a set of built-in command to interact with
Windows (class NBWin32Shell). One can get environment variables, etc. But I
wasn't able to find a way to execute a command on the line and get the
results.


Would someone know of a way to retrieve the MAC addresses in Windows
through the way listed above or any other form from the Pharo image?

thanks in advance,

Usman

 use: MyPackage-Core and MyPackage-Ext or

  It looks to me that the downgrade command is not working. Whenever I
 point to the version preceding the one loaded, the packages are not fetched.

  I am attaching here two files.

  The first (Transcript-PP151) is the output of the transcript as you
 asked. You can see that PetitParser packages as defined by the version 1.51
 are not fetched. All that is loaded is Glamour because the version 1.51 of
 PetitParser loads the latest packages of Glamour. The load works because it
 is an upgrade from the current version of Glamour which is a stable.

  When I saw that only Glamour packages are loaded, I thought of testing
 Glamour downgrade too to see if the problem is specific to PetitParser. You
 can see the result in the second file (Transcript-downgrade-glamour). No
 packages of Glamour are fetched because the configuration tries to
 downgrade it (stable is more recent than 3.0.0 which I try to load).

  In my opinion, downgrade is not working as required. If you want I can
 share my image thru dropbox so that you can have a look to see what might
 be wrong.

 Can you provide a link that describes the use cases for both: ConfigOf

 My elevator pitch for the script api goes like this:

   making #currentVersion obsolete. #currentVersion is bad because it
 does a calculation of
   the current version that can be very slow and sometimes completely

 newer projects always win) and
there is no mechanism for altering those rules. The scripting api
 provides mechanisms for
for bending those rules to fit your needs ... like allowing a
 downgrade of a project.

 Part of the reason that people haven't changed has to do with how
 incredibly difficult it is to change the existing inertia. Another part of
 it is that I continue to support the old way of doing things, so there is

Usman,

With classic Metacello (using the `(ConfigurationOfxxx project version:
'xxx') load` pattern) you can only downgrade via an explicit load of a
particular version of the project. When loading projects indirectly via a
project reference from another project Metacello is biased towards upgrade.

With the Metacello Scripting API[1], you may include an
#onDowngradeUseIncoming: clause to selectively permit downgrades:

Metacello new
configuration: 'DummyParser';
version: '1.0';
repository: '???';
onDowngradeUseIncoming: #('PetitParser');
load.

For additional downgrade options see[2].

Since you are interested in using a specific version of a project you may
also be interested in locking the project[3][4]. With a `lock` Metacello
will not upgrade or downgrade the project but always `honor` the lock
unless an #onLock: clause is used ...

Note that for `locking` to work, you must use the Metacello Scripting API
to do all of your project loads ...

A Moose image comes with the latest development version of PetitParser. So,

(ConfigurationOfPetitParser project version: '1.51') load

But when I try to load the same version within my ConfigOf the expected

I also tried creating a version but it didn't help.

I also had a look at the package the configuration tries to load and
the list shows correct packages to be loaded (see screenshot).

Thanks for your detailed explanations.

Metacello class in my image does not seem to define the messages described
in the documentation for handling downgrading and upgrading conflicts:
https://github.com/dalehenrich/metacello-work/blob/master/docs/MetacelloUserGuide.md#downgrade

I am using Pharo 3.0 with Moose.

Did I miss something?

Usman,

With the Metacello Scripting API[1], you may include an
#onDowngradeUseIncoming: clause to selectively permit downgrades:

Metacello new
configuration: 'DummyParser';
version: '1.0';
repository: '???';
onDowngradeUseIncoming: #('PetitParser');
load.

For additional downgrade options see[2].

Note that for `locking` to work, you must use the Metacello Scripting API
to do all of your project loads ...

Hi all,

But when I try to load the same version within my ConfigOf the expected
packages are not loaded and list of the PetitParser packages loaded remains
unchanged. Here is how my baseline looks like:

ConfigurationOfDummyParserbaseline01: spec
version: '0.1-baseline'

I also tried creating a version but it didn't help.

ConfigurationOfDummyParserversion10: spec
version: '1.0' imports: #('0.1-baseline' )

spec for: #'common' do: [
spec blessing: #'stable'.
spec description: 'version 1.0'.
spec author: 'usmanbhatti'.
spec timestamp: '12/19/2014 16:35'.
spec project: 'PetitParser' with: '1.51'. ].

I also had a look at the package the configuration tries to load and the
list shows correct packages to be loaded (see screenshot).

Does anyone have an idea what may be problematic in my code or that of
Metacello? I am attaching the code of my ConfigOf for a Moose image.

Thanks in advance.

[Pharo-users] STON - new release?

2014-12-08 Thread Usman Bhatti

Hi Sven,

I have used STON to serialize some of my objects and it is really simple
and cool to work with STON. For my project, I loaded the stable version.
When I tried to customize the names of my classes for serialization using
stonName, I got errors of MetaClass DNU. I saw that you already fixed this
problem a few months back. I loaded recent changes and the problem was
resolved.

I would like to load a newer version of STON with this bug fix. Do you plan
to update ConfigOf with a latest release because I would like to avoid
loading a baseline?

thanks.

[Pharo-users] UI testing

2014-09-30 Thread Usman Bhatti

Hi all,

Is there anything in Pharo that supports UI testing?
What I would like to achieve is to be able to simulate a click, select a
menu item, input some text in text fields, Ok/Cancel button click, and some
other basic task for the automation of my tests.

With Glamour, I can simulate transmissions programatically and then test
for the display values in the presentations or dig the resulting morph
structure to test for specific information. The problem with dialog boxes
is that once launched, I cannot perform anything in the system because my
test code is active only when dialog boxes get their intended input and are
validated.

So, if there is anything for simulating testing scenarios (click on
second button - select third menu item - fill up text field - select
color - ok button - test fourth PanelMorph in the window ), it would be
really helpful and make my testing much more productive.

regards,

usman

 There is UITestCase (see the subclasses), e.g.

 testSimulateClick
 self run: #testSimulateClick

 morph := TextMorph new contents: ''; openInWorld.
 morph simulateClick.
 self assert: morph hasKeyboardFocus.


 But it definitely needs more e.g. for pressing buttons and things like

Hi Peter,

For my application needs (English - French), I normally use the gettext

 pharo3 and then seaside via configuration browser.

 But then I had to realize that the seaside-gettext package was not
 installed; and also no gettext package. I found a gettext package in
 the repository http://smalltalkhub.com/mc/PharoExtras/Gettext.

 I installed the package ConfigurationOfGettext, but the
 configuraitonof-browser does not show it. So I installed the package
 Gettext via monticello.

 Then I found the seaside-gettext packages in the repository
 http://smalltalkhub.com/mc/Seaside/Seaside30Addons and installed via
 monticello the packages Seaside-Gettext-Core and
 Seaside-Gettext-Examples.

 Then I open a webbrowser to watch the gettext example. But there I only
 see:

 fontsize

* locale
* locale
* locale
* locale
* locale

 That looks for me like gettext is not working with pharo3 and seaside
 3.1.2

 Any help is welcome - best a mini howto for gettext with pharo3 and
 seaside 3.1.2

Re: [Pharo-users] Updatable trees in Moose browsers (It was Re: Rephrasing my question on Stackoverflow ...)

2014-08-13 Thread Usman Bhatti

Hi Offray,

As Doru mentioned, without a complete example it is difficult to reproduce
and analyze your problem.

For the tree to get updated on node addition or removal, you need to use
GLMAnnouncingCollection to group your nodes. Hence, when you add a new node
in your announcing collection object, this code comes into effect:

updateOn: GLMItemAdded from: #yourself;

So, make sure you are using appropriate collection object.

 I would like to know, what I'm missing.

 An UbakyeNode is a simple data structure with a header (text), a body
 (text) and a list of children, wich are also Ubakye nodes.

 Any advice is welcomed, as always,

 I'm not able to reproduce it again. But as soon as I can catch it again,
 I will be doing it.

  Also, the code you provide depends on the data you have. This makes it
 difficult
 for us to reproduce the issue. If you want to have quicker answers you
 could try
 providing an example that works with simpler objects, or at least
 provide a
 script to setup the data as you need it.


 That's why I was asking (in other thread) how to point to my code
 online. I'm using SmalltalkHub to share this learning project here:

 http://smalltalkhub.com/#!/~Offray/Ubakye/

 but would be nice to point to a published snippets of code about this
 questions. May be I just don't understand how to point to specific code
 online like usually happens with DVCS like fossil or git.

 Anyway if you can load my code from this repository you can then open a
 Playground and run:

 UbakyeBrowser open.

 to see the context I'm talking about.

 Meanwhile, let me illustrate my next question with a image. I have
 already a browser with three panels, as shown here:

 http://www.enlightenment.org/ss/e-53ea868b320b20.66100223.jpg

 - The tree panel, at the left for showing node titles (headers).
 - The content panel, at the top right for showing node content (bodies).
 - The code panel, at the bottom right for writing Smalltalk code.

 I'm able to send message from code panel to another external objects,
 like the usual Transcript, but I would like to be able to send messages
 from the code panel to the tree that is being shown in the browser. I
 would like to start with adding nodes to the current tree, and changing
 its values. How can be this done?


 Thanks for Glamorous Toolkit. I'm really enjoying being able to
 prototype new tools as fast, despite of being  a newbie (¡Power to the
 (newbie) user! --also).

Grease overrides two methods in Collections-Abstract

For the curious ones: in moose loading glamour makes collections-abstract

 I have to little information to say anything. I doubt that it is related
 to Zn logging on itself, but who knows, anything is possible. It seems you
 can reproduce it quite easily. Is there more in PharoDebug.log ?

 In most cases I use #logToTranscript, but with something like

   Hi,
  
   When turning on ZincFileLogger on a Zinc server, after some time (1h
 or so) I get the FileWrite error (see screenshot). I browsed through the
 bugs related to Zinc in the Fogbugz but couldn't find any bug related to my
 problem. I get the problem both on Mac (local machine) and Ubuntu
 (DigitalOcean instance) on Pharo 3.0 (release).
  
   This is my code to register logging on the server events:
  
   server := ZnMultiThreadedServer startOn: 4001.
   logger := ZnFileLogger onFileNamed: 'server-log.txt'.
   server log addListener: logger.
  
   Any pointers?
 
  That is really weird: in the code above the file is named
 'server-log.txt' while in the screenshot the file is named
 'License-log.txt', how is that possible ?
 
  The error is that the file is closed, probably 'underneath' the logging
 code, so the question is, how is that possible, who did that ?
 
  Oops. I renamed the log file name in my mail. I should have had a closer
 look at the screenshot before sending it :((. So, my code should have
 looked like it to match the error in the screenshot:
 
   server := ZnMultiThreadedServer startOn: 4001.
  logger := ZnFileLogger onFileNamed: 'License-log.txt'.
  server log addListener: logger.

 OK.

  Can it be that two file (descriptors) got swapped ?
 
  Did you save the image, move it around, across machines ?
 
  I had this doubt of moving my development image to the cloud instance so
 I created a script on the cloud instance to prepare my server from a

[Pharo-users] changes and sources file availability

2014-04-02 Thread Usman Bhatti

Hello,

In Pharo 2.0, we could enforce the image not to look for sources and
changes file at the startup with:

SmalltalkImage
   checkChangesFileAvailability: false;
   checkSourcesFileAvailability: false.

I could not found these selectors anymore in my Pharo 3.0 image.

Clement mentioned to me a while ago that it was due to the change of
compiler (Opal) and it might not be safe to remove these files (if I
remember correctly). So, my question:

1/ Can I remove these two files safely from my production image?
2/ If the answer to 1/ is yes, how can I tell my image not to look for
these files at image startup?

Re: [Pharo-users] [gsoc-mentors] GSoC: call for ideas

2014-02-13 Thread Usman Bhatti

[Anne Etien could not post this msg on the mentors list I m forwarding it
on her behalf].

Title: FAST JavaScript model

Level: advanced

Possible mentor: Anne Etien

Possible second mentor: Nicolas Anquetil or Yuriy Tymchuk

Description:
For in depth source code analysis a support of abstract syntax trees is
required. FAST is an abstract syntax tree extension for FAMIX meta-model
that is used by Moose technology. The goal of this project is to create
a JavaScript version of FAST.

Technical Details:
As programming languages are different, their AST representations are
different too. FAST model aims for creation of as generic as possible
core that can be extended for different languages. Also the structure of
a model allows creation of generic algorithms like symbol resolution,
metrics calculation and rule checking that will work for any language.
Prototypes of FAST for Smalltalk and Java are already implemented.
During the project a student will implement the JavaScript model. More
detailed information about FAST is provided in the Moose day
presentation: http://youtu.be/dRr3WHOD3x4

Benefits to the Student:
The student will gain a deep understanding of a JavaScript syntax and
abstract syntax tree model. He will also learn about PetitParser
framework, and gain knowledge about software modeling and analysis.

Benefits to the Community:
Community will get a FAST model for JavaScript that can be used for
software assessment with Moose. Also this model can be used later in PhD
projects such as automation of source code translation. With this third
model, the community will have raw material to real think and improve
generic algorithms based on AST.

 I know nothing about the (extra) limitations of the Windows VM.
 But on Linux you can allocate close to 1GB (see mailing list).
 On Mac you seem to be able to get pretty close to that (see Phil's
 answers).
 So switching hardware/OS is an option too ;-)


I would be surprised if the client agrees to it :). So that I can't (SAS
will take some time to come).
So, may be currently, we'll have to resort to some optimizations through
serialization and de-serialization, but memory limitation is going to be a
recurrent problem for us.
