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

by Esteban Maringolo

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.

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

by Esteban Maringolo

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) compared, e.g., with Dolphin Smalltalk via ODBC (62ms). The time of the execute call to return is instantaneous, so I think the issue might be in the creation of the result set. Is this a known issue? Should I check something else? Thanks in advance, [1] https://github.com/tesonep/pharo-com/pull/10 Esteban A.

Re: [Pharo-users] evaluation of the expression 7 factorial

by hogoww

Hi, It's just that the printing buffer cannot contain all the characters (the last digit is most probably justÂ a line down !) This happens often when using a size that is not small because the GUi object is not getting bigger :) (which is still not good) Pierre On 10/03/2020 17:47, Rene Paul Mages (ramix) wrote: > Hello, > > As you can see : > > http://ramix.org/pharo/version-8.0/7-factorial.png > > the result of the following evaluation is not 5040 : > > 7 factorial > > Nota Bene : my linux laptop is running the 64 bits version of Pharo 8.0.0 >

Re: [Pharo-users] evaluation of the expression 7 factorial

by Esteban Maringolo

Try inspecting the result (Cmd+i) instead of printing it. The print result is breaking the number (5040) in two lines, but you only see the first three characters. Regards! Esteban A.

Re: [Pharo-users] Pharo 8 stability and large images

by Vince Refiti

I am very happy to hear this as stability is something I worry about all the time. Pharo is the fastest way for me to get from thought to working code, and it is good to know that I can also depend on it for serious deployments. I have to ask though - how does one get to an image size that is ~1gb in size? By saving working data in the image itself instead of in a database perhaps? Vince
