[Glass] Moving data from Pharo with SIXX

[Dale K. Henrichs]

Mariano, 

I haven't actually used SIXX in years so it will take some time for me to blow the dust off my SIXX SKILLZ:) 

The LargeInteger class is new in 3.x so that one is not a surprise ... Having to map True and False is not surprising since they are classes that don't exist in GemStone ... I almost think that perhaps True and False being required might be indicative of a bug on the pharo side, since I seem to recall that SIXX has the notion of Booleans builtin so the True and False classes should be masked on the creation side ... then again I could be remembering this wrong:) 

I assume that a set of standard mappings for classes could be created, and I'm curious if any of the folks that use SIXX have done so?

| Thanks Dale for the links.
| So, I installed SIXX in Pharo with:

| Gofer new
| squeaksource: 'MetacelloRepository';
| package: 'ConfigurationOfSIXX';
| load.
| (Smalltalk at:#ConfigurationOfSIXX) load.

| And I serialized into a text file sending #sixxString.

| In GemStone I installed SIXX with:

| Metacello new baseline: 'SIXX'; repository:
| 'github://glassdb/SIXX:master/repository'; load .

| and tried to materialize with #readSixxFrom:

| Now...the problem is that first, it barked because the class
| LargePositiveInteger didn't exist. So I found a workaound doing:

| srs := SixxShapeChangeReadStream on: (FileStream oldFileNamed:
| 'myFile.xml'). srs shapeChangers at: #LargePositiveInteger put:
| LargeInteger.
| srs next.

| Cool. I continue and now it barks because it doesn't find the class
| False.....
| So.....I thought the SIXX serialization between Pharo and GemStone
| managed this stuff. Am I doing something wrong or I need to manually
| map all these classes?

| Thanks!

| | | Hi guys,
| | 
| 

| | | I want to start testing my app in GemStone and one of the things
| | | I
| | | would need to do first is to move some that. I understand that
| | | most
| | | of the people use SIXX.
| | 
| 
| | | So..what things should I be careful while serializing? sorted
| | | collections? closures?
| | 
| 
| | | Floats? DateAndTimes? ScaledDecimal ...
| | 
| 
| | | In other words...is there any known type of object that I should
| | | not
| | | move with SIXX to GemStone?
| | 
| 

| | | Any blog post or something about
| | | using/installing/serializing/materializing SIXX for this task?
| | 
| 

| | | Thanks in advance!!
