[Pharo-users] Usage of String and FileLocator to reference files in ZipArchive (and probably other places)

[Hans-Martin]

Hi, I've stumbled upon a 7.0 incompatibility with regards to how file names
are treated.
In 6.1, I can use Strings and FileLocators interchangeably to create and
read Zip archives. That's because StandardFileStream does the magic behind
the screnes.
In 7.0, StandardFileStream has been deprecated, and "File
openForReadFileNamed:" is used instead. That method does not handle
FileLocators, so code that uses FileLocators to open Zip archives ceased to
work.

What's the preferred solution? It strikes me as illogical that objects which
were made to reference files can't be used to reference files in these
contexts. However, there may be a conscious design decision behind this
change that's just not obvious to me.

Cheers,
Hans-Martin

Could you give a code example ? What API/methods are you talking about ?

What worked before and does not work anymore ?

*NO* you should not use File directly.

Just use FileReference instances (however you create them) and work from there. 
If you got a string path, use #asFileReference.

  FileLocator desktop / 'foo.txt readStreamDo: [ :in | in upToEnd ]

MyObject>>#readFromFile: file
  ^ file asFileReference readStreamDo: [ :in | self readFromStream: in ]

Re: [Pharo-users] Usage of String and FileLocator to reference files in ZipArchive (and probably other places)

[Hans-Martin]

Ok here's an example:

ZipArchive isZipArchive: FileLocator temp / 'nonexist.zip'

In 6.1, this brings up the nonexistant file dialog if the file does not
exist, otherwise it returns true or false depending on whether the file is a
zip archive.
In 7.0, you get an error "Instance of FileLocator did not understand
#utf8Encoded" independent of whether the file exists, is a zip archive or
not :-)

Hans-Martin

Do you think there is anyway we could run one of these virtually? I would love 
to have been involved, but finding time to travel is tricky. A virtual (or 
blended) event would be much easier. If it helps, I have a corporate Zoom 
account thst would support up to 500 participants - gotta think big :-)

Re: [Pharo-users] Usage of String and FileLocator to reference files in ZipArchive (and probably other places)

[Sven Van Caekenberghe]






ok, I had a quick look.

the whole ZIP archive code has quite close ties with File (and vice versa: a 
lot of methods on File are only used by that code), while I don't think this is 
strictly necessary.

I know that this has historical reasons.

some more work needs to be done here.

[Pharo-users] Pharo on Linux

[Richard Kenneth Eng]

I'm running Debian. At http://files.pharo.org, I download

   - platform/Pharo6.0-64-linux.zip
   - sources/PharoV60.sources.zip
   - wget -O- get.pharo.org/60 | bash

Then I try: ./pharo Pharo.image &

I'm always getting "This interpreter (vers. 68021) cannot read image file
(vers. 6521)."

What's wrong?

Re: [Pharo-users] Pharo on Linux

[Alistair Grant]

Hi Richard,

You're mixing 32 bit and 64 bit installations.  I'd just use the
zero-conf install.  In an empty directory:

curl get.pharo.org/64/61+vm | bash

or

wget -O - get.pharo.org/64/61+vm | bash

HTH,
Alistair

How do I run pharo?

./pharo Pharo.image &

Re: [Pharo-users] Pharo on Linux

[horrido]

Thanks.

The last time I used Pharo for Linux was over a year ago, and ./pharo
Pharo.image worked then. Every time usage convention changes, it breaks
documentation and causes confusion. Having more than one way to do something
always invites confusion.

Such is life as a programmer.

./pharo Pharo.image never launched an UI for me for images I got from
zeroconf on linux.

It will launch an image, but the image will close immediately after
because it has nothing to do while pharo-ui will stay open because it
has the ui process to interact with the user.

./pharo Pharo.image --eval "10 second wait" will keep the image open 10
sec for example.

[Pharo-users] External module not found

[Richard Kenneth Eng]

I have a most peculiar problem. I've been using Pierce Ng’s PasswordCrypt
 encryption
package with Pharo 5. Now that I'm using Pharo 6, it doesn't seem to work
anymore. The ffiCall:module: message always gives me "External module
not found".

So my question is, what alternative package can I use to replace the it for
Pharo 6?

Should I go back to Pharo 5?

Re: [Pharo-users] External module not found

[Bernardo Ezequiel Contreras]

i've seen that error when i forgot to put a link to sqlite3 (libsqlite3.so)
near the VM. are you sure that the VM have access to the external library?

Re: [Pharo-users] External module not found

[horrido]

That's what I'm trying to determine. This used to work before with Pharo 5.

With the latest Pharo setup, it's not clear where I'm supposed to place the
libshacrypt.so file. It has to be located where the Pharo VM can find it, I
presume.

This may be a 32 vs 64 bit issue. I am investigating...

[Pharo-users] Issue with starting 32-bit Pharo under Linux

[Richard Kenneth Eng]

I'm running 32-bit Debian.

I installed 32-bit Pharo 6.1 using:
*wget -O- https://get.pharo.org  | bash*

When I try to run Pharo with:
*./pharo-ui Pharo.image &*

I get this error:

PrimitiveFailed: primitive #createDirectory: in UnixStore failed

And when I try to close the image, I get this error:

PrimitiveFailed: primitive #primSize: in MultiByteFileStream failed

What's going on???

[Pharo-users] Loading ZincHTTPComponents iget stuck in Pharo 7.0.0.RC1-32 bit in Win 10

[Sanjay Minni]

Hi I am trying to load one of our packages which is up and running in Pharo
6.1 in Pharo-7.0.0.RC1
(Pharo 7.0.0.RC1 32bit in Win 10)

It gets stuck at Loading Zinc-Character-Encoding-Tests-Sven43, 
the environment freezes no further messages.
I tried loading only ConfigurationOfZincHTTPComponents in a fresh image -
same result (loading 2.9.2 of Conf...ZincHTTP...)

how to get around this

Your old 32 bit .so will definitely not work with 64 bit. And does it work
with Pharo 6.1?

For Pharo 7 you need to load #bleedingEdge

Or better still, the baseline in https://github.com/svenvc/zinc

See the Travis CI build there
