Oh, I forgot that problem happens in Pharo 7 stable and any Pharo 8
(dev). Sorry for the late info. It seems to be related to git
implementation/interface with windows 10 system.

Currently I'm developing a  deep learning tool to detect stolen cars. It
interfaces python stuff (Keras/Theano via Atlas stuff) using Pharo and
seaside foregrounds... Have fiddled a little with the NeuralNetworks
package, but decided that Keras/Theano are better an if things go bad I
can always turn back to python. Last project using Pharo was a
certification system, but due to the signed NDA I couldn't publish
anything (pain...). This one is easier to explain: detect cars passing
through checkpoints, snapshot car, identify plate, identify windshield
in order to capture faces inside the car. If plate indicates problem,
notify authorities and try to identify faces. Depending on results (on
faces) notify police regarding danger of armed reaction. High resolution
cameras.

Best regards,


Casimiro

[Pharo-dev] PLZ fix it for Pharo8...

[Casimiro de Almeida Barreto]

In the last builds of Pharo8, CatalogBrowser comes with an easily
fixable glitch... Please could someone take a look? My humble suggestion is:

===

createRepositoryURLtoNameMappings
    "Return a mapping between repositories URLs and their user names"

    
    |repos|
    repos := Dictionary new.   
    3 to: SystemVersion current major do: [:v |
        repos    
            at:
('http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo{1}0/main' format:
(Array with: v))
            put: ('Pharo{1}.0' format: (Array with: v)].
    repos at: 'http://www.squeaksource.com/MetacelloRepository' put:
'Unsorted'.       
    ^repos

[Pharo-dev] Doubts on Garage (1st use)

[Casimiro de Almeida Barreto]

Good evening,


I was trying to sanitize statements, but something went awkward. The 
following non sanitized codelet works ok:


    str := 'INSERT INTO chaves_de_encriptacao (
                    numero_funcional,
                    chave_privada,
                    chave_publica) VALUES (''',
                    self personId leaId asString,''', ''',
                    self keyPair privateKey asAsn1DerBytes asByteArray 
hex,''', ''',
                    self keyPair publicKey asAsn1DerBytes asByteArray 
hex,''')'.


    [ dbConnection execute: str ] on: Exception do: [ ^ false ].


But sanitized one:

    str := dbConnection createStatement: 'INSERT INTO 
chaves_de_encriptacao (

numero_funcional,
chave_privada,
chave_publica) VALUES (''?'', ''?'', ''?'')'.

    str prepare.

    str at: 1 bind: self personId leaId asString.
    str at: 2 bind: self keyPair privateKey asAsn1DerBytes asByteArray hex.
    str at: 3 bind: self keyPair publicKey asAsn1DerBytes asByteArray hex.


    str execute.


returns exception mysqld_stmt_send_long_data (obviously same thing 
happens with the shorthand


str := dbConnection prepare: ...

And I inspect most things but could not understand what's going bad.

As SQL is not my field, I wonder if someone could help to elucidate 
what's going on.



Best regards,

Good evening,

 

Is there a implementation of PGP signature/encryption protocols in pharo?

I have a feeling that you are working on the wrong level, consider:

file := FileReference newTempFilePrefix: 'data' suffix: '.txt'.
file writeStreamDo: [ :out | out << 'Casimiro de Almeida Barreto' ].
file contents.
file ensureDelete.
file exists.

The #newTempFilePrefix:suffix: method uses 'FileLocator temp' as target 
directory, which will be different on different platforms.

The trick is to use these FileLocator locations, try 'FileLocator 
supportedOrigins', to have an abstract, cross platform starting point (except 
for the Windows drives, obviously). Then you construct directories using 
messages.

Remember, the whole image, file browser, file dialogs, they all work cross 
platform, so you can do so too.

Complete transparency is not possible because the concepts of file system in 
Windows and Unix are different. While in Unix you have a continuous tree, in 
Windows you have the concept of drive or 'disk unity' (C: D: E: ...) and 
disjunct trees. Also in Unix you can have complex file names that include 
almost all characters while in Unix some characters cannot be used (like : )... 
Not to mention that file properties in Unix and Windows are not exactly the 
same, links are not the same, so on and so forth.

It seems that FileSystem does not convert / into \ .
((FileSystem root) / 'c:\temp\tempfile.txt')  writeStream won´t work but...
FileStream fileNamed: 'C:\temp\tempfile.txt' works ok.

So... I could make it work for getting a stream both for Unix and Windows:

OSPlatform currentPlatformName = 'unix'
ifTrue: [
[ str := (fs / fn) writeStream ] on: Exception do: [ ^ nil ] ]
ifFalse: [
[ str := FileStream fileNamed: fn ] on: Exception do: [ ^ nil ] 
].

And to delete:

OSPlatform currentPlatformName = 'unix'
ifTrue: [
(FileSystem root / aFileName) delete ]
ifFalse: [
rgx := RxMatcher forString: '^[A-Z]\:'.
drive := rgx matchesIn: aFileName.
drive := (drive at: 1) copyWithRegex: '\:' matchesReplacedWith: 
''.
((FileLocator driveNamed: drive)  / (aFileName copyWithRegex: 
'^[A-Z]\:' matchesReplacedWith: '')) delete ]

Not good, nor elegant nor anything close to good transparent code but... works 
:'(

There is also the following option:

    FileLocator C / 'temp' / 'e8720bb4-b90a-0d00-9b1f-008709e5552b.txt'

[Pharo-dev] Problem with FileSystem in WIndows

[Casimiro de Almeida Barreto]

Good night all.



I´ve had trouble in windows concerning FileSystem.



((FileSystem disk root) / ‘C:\temp\e8720bb4-b90a-0d00-9b1f-008709e5552b.txt’) 
delete



Fails as if the file didn´t exist. Message:



FileDoesNotExist: Path / ‘C:\temp\e8720bb4-b90a-0d00-9b1f-008709e5552b.txt’



And I wonder what´s wrong. Because it works in linux and MacOS.



Trasncript show: ((FileSYstem disk root) / 
‘C:\temp\e8720bb4-b90a-0d00-9b1f-008709e5552b.txt’)



Returns:



File @ C:\temp\e8720bb4-b90a-0d00-9b1f-008709e5552b.txt\



And I wonder where the last \ came from and if is it that is messing all and 
how to fix things.

There are some troubles with ssl in Fedora (didn't test it in Ubuntu).
While loading Woden (for instance) there's a crash (exception) because
ZdcPluginSSLSession fails.

BTW, the threaded version requires to be run as super user because it
tries to do a pthread_setschedparam(). I tried to fiddle with
/etc/security/limits.conf... but it's not something fancy to do...
