Re: [Pharo-users] Fuel version

by Mariano Martinez Peck

Johannes, The simples approach is that you materialize your object in 3.0, then load the same version as fuel from pharo 4.0 and then serialize again in 3.0. After that, you can materialize in 4.0. The other alternative is that in 4.0 you load older version of Fuel (the one in 3.0), then import, the expert, then load new fuel again. I have been doing this since Pharo 1.4 until 4.0 since my client's app also uses Fuel. And the process was always quite simple and only once per release. Migration is something we miss in Fuel..and even if we have promised to keep format unchanged, sometimes the evolution of Pharo itself (not the internal Fuel format representation) makes the format to be broken from one version to the other. So until we have a better automagic migration tool, the above trick should work. Also...see this link: http://rmod.inria.fr/web/software/Fuel/Version1.9/Documentation/FormatMigra… Btw...here is the scrip I used to migrate from 1.8 to 1.9... this is just an EXAMPLE of how you can do it..but do not copy it becuase it uses old version of the code repositories, etc... | oldVersion newVersion fileNames objectsByFileName materializerClass | oldVersion := '1.8'. newVersion := '1.9'. fileNames := #( '/Users/mariano/XXX/aaaaDB.fdb' '/Users/mariano/XXX/bbbbDB.fdb' '/Users/mariano/XXX/ccccDB.fdb' '/Users/mariano/XXX/ddddDB.fdb' '/Users/mariano/XXX/eeeeDB.fdb' '/Users/mariano/XXX/ffffDB.fdb' ). objectsByFileName := Dictionary new. materializerClass := Smalltalk at: #FLMaterializer. fileNames do: [ :fileName | objectsByFileName at: fileName put: (materializerClass materializeFromFileNamed: fileName).

So he didn't find http://pharo.org/documentation ? It is the first hit if you search for 'Pharo Documentation' ! Of course, one on one mentoring is way better than any documentation for anything. > On 30 Apr 2015, at 13:40, Sergio Fedi <sergio.fedi(a)gmail.com> wrote: > > Note: I haven't read the reddit link above) > > I recently (2 weeks) begun working with a total neophite to St and there is a lack of proper Tutorial/Documentation to get you started doing something. > > When I say that there is a lack, I mean that this person (who is well versed in looking up stuff on the internet) couldn't find proper material for getting started. > (whether this material does not exist or exists but is difficult to find, I don > t know) > > âAnd it's not have been the first time this happened to me. > > So far, my best (fluid, straightforward) experiences learning St has been when someone else taught me. >

Re: [Pharo-users] Reading rows in a database table (select * from ...)

by Sergio Fedi

I don't know if this is your case, but I remember our team having a problem in SQL selects. Th rows it retrieved where very volatile; after the first read they dissappeared. So the first step was to save them/copy them into a ST object and then process them. (this was due to the memory of each record been in a temporary memory buffer) âAs I mentioned before, I don't know if this is your case.

Note: I haven't read the reddit link above) I recently (2 weeks) begun working with a total neophite to St and there is a lack of proper Tutorial/Documentation to get you started doing something. When I say that there is a lack, I mean that this person (who is well versed in looking up stuff on the internet) couldn't find proper material for getting started. (whether this material does not exist or exists but is difficult to find, I don t know) âAnd it's not have been the first time this happened to me.
