Re: [Pharo-users] Generate class hierarchy from JSON Schema

Hi, To feed a Pharo app I need to read from an old MDB file, via ODBC. So I tested PharoADO and, after adding a missing Variant Type [1], I got my query working (at least read only). However the time of ADOClient to return a query with 10K rows of 5 columns each is extremely slow (+65000ms) comp

Re: [Pharo-users] Generate class hierarchy from JSON Schema

As an additional reference, I attach the profile tally for the query I'm mentioning. The culprit seems to be the calculation of the ADOField properties that might be calculated on every call. Regards, Esteban A. Maringolo On Wed, Mar 11, 2020 at 2:13 PM Esteban Maringolo wrote: > Hi, > > To

Re: [Pharo-users] Generate class hierarchy from JSON Schema

Hi Esteban, Thanks for reporting this issue. I haven't made any "stress" tests yet for ADOClient. Could you please try to use ADORecordset as described in the readme? There you have a direct access to each record at a time, and then you can create your own "loop" to process the query result. I

--- Begin Message --- Hi again Apparently, the issue is on the VM side. I unpack the 9.0 VM into the 8.0 folder, and everything went fine. Looks like there is an issue on windows when getting the latest 8.0 VM. Looking the the dev mailing list, I can see a similar issue has been raised, when yo

Re: [Pharo-users] Generate class hierarchy from JSON Schema

The profiling using the recordset was even worst. I changed the iteration [1] to add everything to a collection, but most of the time is spent in #calculateMethods and #calculateProperties. Which is performed everytime for each ADOField. I wouldn't consider this a stress test, but maybe the method

Re: [Pharo-users] Generate class hierarchy from JSON Schema

I did a small change in ADORecordset to have the fields as an instVar and also in ADOFields to have each ADOField in an `items` instVar. It is still slow compared to an ODBC API, but I got a 20x speedup (~1000ms), that is spent mostly on the actual call to the dispatcher to fetch each cell value.

Re: [Pharo-users] Generate class hierarchy from JSON Schema

Follow up. Seems that playing with these COM/ADO objects in the playground messes with the VM; so I'm getting weird image crashes, where the image closes without any notice. Do you experience the same? Esteban A. Maringolo On Wed, Mar 11, 2020 at 4:11 PM Esteban Maringolo wrote: > I did a s

Re: [Pharo-users] Generate class hierarchy from JSON Schema

Thanks for the PR! Maybe something can be done also on the PharoCOM level within calculateMethods and calculateProperties. I didn't experience any crashes, although I developed PharoADO on 32bits in Pharo 7 and Pablo upgraded PharoCOM to 64bit after Pharo 8 was released. Besides, I haven't man

[Pharo-users] How to get a list of package versions?

Hi there, I would like to compare two Pharo deployed images. Specifically, get a list/tree of the installed packages with their version number each one, so I can compare if there were updates between both deployments. I started by doing IceRepository registry collect: #workingCopy Then discover
