Muiltple images / FFI

by recursive68＠gmail.com

Hi, I have an app (seaside) that is configured with multiple pharo (1.3) images behind an apache proxy, using a FFI wrapper to a OCI native library to connect to Oracle. It works fine with one image but with multiple images it crashes with a seg fault/memory error when under user load. The error appears to happen when the wrapper code closes an OCI statement/connection. It appears with multiple images that they are allocating/de-allocating memory via the wrapper/OCI and over-writing each over. Is that possible ? Thanks

You probably want to do something similar to what we have done in Deltawerken-Framework. (on ss3) Stephan

Re: [Pharo-users] XSD handling in Pharo

by Brenda Larcom

I have some partly-finished Squeak code that creates a schema-specific validating XML parser & generator (well, data objects that do this) given an XSD. My motivating use case is to enable quick support of new XML-based file formats. So, you would design your objects as usual, then run my schema parser, which would stub out objects to parse & generate the new format. Then you would write tiny conversion methods between your objects and the new ones. Poof! Support for a new file format. Partway through I found an enormous Java library that did something similar; it may be the one Phil mentions below. The one I recall was pretty big (13 namespaces) and I decided not to just port it because it seemed more complex than I thought was needed. On the other hand, it is finished, whereas.. I have been too busy to work on mine for several years now :( . So, I will hunt for it tonight & put the latest version somewhere other people can get & work on it. I don't remember what state it is in, but I never do so I think/hope it has lots of comments & tests for how I intended it to work. The other catch (besides it being half-finished) is, if/when I eventually start working on it again, I will turn it into a completely pedantic validating parser/emitter, because I want it to e.g. prevent XML injection without conscious thought from the developer using it. I am happy to help/advise anyone who wants this same goal to meet it, but if you want to add direct accessors or anything else that routes around the validation, please do so in a package that extends mine (in the same classes is fine) so that I can still meet my original intent when I eventually get back to it.

Re: [Pharo-users] Morphic text filed plus autocompetion

Hi all, also notice that the default text entry widget has already an autocompletion feature. see WidgetExamples>>exampleTextEntryWithCompletionDialog You can find several uses of it. See EditorFindReplaceDialogWindow>>newFindTextEntryMorph as another example.

Re: [Pharo-users] XSD handling in Pharo

I mean that XSD is XML indeed but the usage is for defining structures, and crafting all kinds of artifacts from there. I was involved with a project where a ton of XSDs were used to define business message structures. Reading XML is not giving us reading XML with XSD schema validation nor Classes generated from XSD files (as does Java JAXB). https://jaxb.java.net/2.2.7/docs/ Phil On Tue, Oct 1, 2013 at 10:10 AM, Norbert Hartl <norbert(a)hartl.name> wrote: > > Am 30.09.2013 um 19:35 schrieb phil(a)highoctane.be: > > > XSD is not the same. > > > What do you mean? > > Norbert > > > Guess you want to do something like JAXB or schema validation.
