Related to my previous post, here is the 'out of the box' experience
of a newbie. The image was downloaded from the Web site and untouched.
The 'How To' seems to be out of sync with the software.
Configuring for Magma.
Why does it have to be
configured for Magma? What is the default
persistency system?
In application 'pier' configuration.
This is the Pier > configure link on the Pier home page.
1. Add WAMagmaConfiguration to configurations.
I
am assuming that this is in the 'Configuration Ancestors' area?
2. Switch sessionClass to WAMagmaSharedSession
There is now a General > sessionClass with an override link.
I am assuming that we have to press Save at this point...
3. Return to the config app and click the new
'magma'.
There is no direct link, so I pressed Done and clicked again on
the
configure from the Home page.
In the General section there is a override link next to Location > Magma
4. Create RepositoryRoot selecting PRMagmaRepository
(create)
No such thing... The choices for Magma > Locations are
- MagmaRemoteLocation, and
- MagmaLocalLocation.
Not sure what to do, I selected MagmaLocalLocation and left 'magma' in
the path field. Then pressed Saved.
5. Return to config app and click the 'pier'
link.
There is no Pier link. Only a Pier section header.
6. Switch the kernel to the persistency scheme of your
choice.
For the Kernel the choices are:
- "None", or
- "a Pier kernel named: 'Pier'"

Configuring
for Magma.
Why does it have to be configured for Magma? What is the default
persistency system?
The default is PRNullPersistency, the data is all in the image. If you
save the image you save the data. There is an option PRImagePersistency
which does a periodic image save for you.
If you switch to PRMagmaPersistency it is likely to tell you that it has
not yet been configured. Hence the explanation for this 'non-trivial'
case in the How-to.
In application
'pier' configuration.
This is the Pier > configure link on the Pier home page.
1. Add WAMagmaConfiguration to configurations.
I am assuming that this is in the 'Configuration Ancestors' area?
2. Switch
sessionClass to WAMagmaSharedSession
There is now a General > sessionClass with an override link.

'magma'.

At this point you are missing a vital piece of seaside information.
The config app refered to is again /seaside/config
username: seaside password: admin
where before you would have seen
pier 'configure' 'remove' 'pier'
you should now see
pier 'configure' remove' 'pier' 'magma'
There is no direct link, so I pressed Done and clicked
again on the
configure from the Home page.
In the General section there is a override link next to Location > Magma
> 4. Create RepositoryRoot selecting PRMagmaRepository (create)
>
If you clock on 'magma' you will be taken to an entirely new page that
you have not yet seen which has the Create Button on it.
No such thing... The choices for Magma > Locations
are
- MagmaRemoteLocation, and
- MagmaLocalLocation.
Not sure what to do, I selected MagmaLocalLocation and left 'magma' in
the path field. Then pressed Saved.
thats fine.
5. Return to
config app and click the 'pier' link.
There is no Pier link. Only a Pier section header.
6. Switch the
kernel to the persistency scheme of your choice.
For the Kernel the choices are:
- "None", or

Thanks Keith.
I gave it another try following your hints. Here are more notes, again
from a newbie approach. I found many issues:
1- Minor: Default port
The default proposed port is 8080. This conflict with usual Tomcat
installation. Changing the text to 9090 does not seem to change the
underlying hot link. Being new to Squeak, I do not know how to change
that. I had to do the classic highlight+do it. I would recommend
changing the default port or let the user choose themselves (remove
the hot link).
2- Major: Froze Squeak clicking 'Over' in the debugger
Going to seaside/config then Pier>Magma I got an error about a
filestream (more about that below). I clicked debugged. Inspected the
variables in Squeak. I found that a directory was set to c:/tmp/magma.
I thought that maybe the issue was with the Windows path (\ vs. /). I
changed a variable and clicked Over. Oops... Squeak would not respond
anymore to any click. The web site still worked. How does one unfreeze
Squeak in such situation? Crtl-C did nothing.
3- Critical: Magma error following instructions
I removed every thing and started over: fresh 3.9 Squeak + fresh SMP
image. Following the How To I clicked on PRMagmaRepository > create. I
got an error:
Repository Path Setting: magma
c:\dev\Squeak\SMP\magma\objects not found
The above file and directory do exist...
Further clicking brings an error page. Here is the top of the stack:

Squeak uses ctrl '.' as a user interrupt, as in ctrl 'stop'. Its
an
apple thing, or at least it was an apple thing.
I have had this problem or very similar to what you describe. Sometimes
using the website unfreezes the squeak ui. I am using (knoppix) linux,
and I solved it once and for all by going back to vm version 3.6-3,
which predates some newer IO code.
3- Critical: Magma error following instructions
I removed every thing and started over: fresh 3.9 Squeak + fresh SMP
image. Following the How To I clicked on PRMagmaRepository > create. I
got an error:

they should be created when you click on 'create', it can take some time
to complete.
I dont think that you need to manually create the 'magma' directory.
Other than that I dont know.
I admire your persistence, if you pardon the pun,
It sure worked more easily for me.
I am planning to release an updated SMP image later this week.

10:46 p.m.
Trying again from the beginning.
I re-dowloaded the files from
http://ftp.squeak.org/various_images/Seaside-Magma-Pier/
and
http://ftp.squeak.org/current_stable/win/Squeak3.9-win32.zip
But I got stuck again at the same place:
4. Create RepositoryRoot selecting PRMagmaRepository
(create)
There is a magma direectory created, and it contains for files:
applied.images, commitPackages, objects, objects.idx.
Ignoring the error message:
Repository Path Setting: magma
c:\dev\Squeak\SMP\magma\objects not found
I clicked on 'create'. I got:
Outage occurred while writing system-definitions! Will
now attempt to repair.
Clicking on Ok I get again:
MaUserError: fileStream required
The top of the stack is included below.
The generated error is at:
.....................
MATransactionalFileStream class
fileStream: aFileStream
aFileStream ifNil: [ MaUserError signal: 'fileStream required' ].
^ self new
setFileStream: aFileStream ;
yourself
.....................
aFileStream is nil.
The calling method is:
......................
openFile: unqualifiedName
| answer |
answer _ MaTransactionalFileStream fileStream: (directory fileNamed:
unqualifiedName).
answer
ifNil: [ MagmaEnvironmentError signal: 'Could not open files in ',
directory pathName ]
ifNotNil: [ answer binary ].
^ answer
......................
I inspected 'directory fileNamed: unqualifiedName'. It indeed returned nil...
directory is set to DosFileDirectory on 'C:\dev\Squeak\SMP\magma'. As
far as I can see this is correct.
unqualifiedName is set to 'objects'. This also seems correct, and the
file exists.
I attempted to follow the issue with the debugger:
The method MultipleByteStream
open: fileName forWrite: writeMode
fails at:
fileID := StandardFileStream retryWithGC:[self primOpen: f writable:
writeMode]
until:[:id| id notNil]
forFileNamed: fileName.
fileName looks ok but fileID is nil.
Of course at this point the file might be locked from the previous failure...

I started to wonder if the problem could be with Windows. So I did a
full install on Fedora (C5, under colinux). I do not have a Mac for
trying that.
Same problem...

Quite a lot of problems with the Squeak environment...
Because of the previous issues, I decided to try updating Magma and
other Packages.
I must say that I am underwhelmed with the SqueakMap system. Few days
ago I was using YumEx for Fedora. I found the dependency management
more clear.
Anyhow, I first tried to update Magma. localhost:9090/seaside/pier
refused to work... I tried updating other packages. Still no luck.
Then I tried opening a fresh 3.9 image and running the Pier
installation script. Again many not very clear messages about loading
older versions of some MA * packages. The choices are yes and no.
That's not clear what the implications are. I picked yes for all of
them. I then got an error message about a missing MATestCase class...
My perception as a newbie is that there is quite some version
management issues here. The whole process stopped because of a syntax
error (probably due to a different class schema version).
I am not sure what to do next...
