Encoding problems with web application
by Erwin Sistinger 31 Oct '05

31 Oct '05

Hello, since 1 year i have had a small xotcl web application running on a server with Redhat Linux (don´t know the version, changed since), xotcl 1.1 (i´m using the actiweb packages), mysql 3.23 and mysqltcl installed on it. A few weeks ago the admin of the server upgraded to a new redhat version and also to mysql 4.1.14. Since then the encoding of the web pages my application delivered was not correct anymore - characters like ü or ä weren´t displayed. I changed the charset-information in the html-header to utf8, converted my old database (which was in iso88591) to utf8 and upgraded to mysqltcl 3.0.1 - still no utf8-characters in the html-pages. I tried to find a solution within the actiweb code but although i found some lines with "encoding" in I it don´t really know what is happening in there - could anybody please give me a small hint? Thanks a lot, Erwin the server´s configuration: Redhat Linux 3.0ES xotcl 1.1 (i´m using the actiweb packages) mysqltcl 3.0.1 mysql 4.1.14 -- Lust, ein paar Euro nebenbei zu verdienen?

Extending nonposArgs in XOTcl
by Shawn Jury 26 Oct '05

26 Oct '05

Hello, I am trying to extend nonposArgs to include more checks and I am having a hard time. I have gotten basic checks working, but I am not able to get some of the more complicated checks working. The tutorial shows that the syntax for extending nonposArgs is: *someobject|someclass* *proc|instproc* methodName {?optional arguments? argName args} { ... } I have not been able to get the ?optional arguments? to work. Example: I am trying to get some checks done that will check for specific values of the Arg. I would like to be able to pass those values into the check. xotcl::nonposArgs proc RANGE {allowedRange argName args} { .....code to verify the range } The syntax to use this would be similar to: Class Foo Foo instproc setMtu {{-mtu:RANGE 54-65535 "1500"}} {} { .... } This is similar to what Giovannni Cristelli asked in the post titled XOTcl extending nonPosArgs class from November 2004. Is there any way to do this currently? I am trying to replace a bloated package that is currently being used which has many of these checks available. I have tried many combinations of syntax to get this to work and have not been able to figure it out. Thanks, Shawn

Well, the subject says it all. That Tcl option seems to be missing from the XOTcl equivalent. / http://www.fishpool.com/~setok/

If something is leaking memory it is most likely more complicated than just object creation and destruction. At least on my system the following script runs without any leaks. for {set i 1} {$i < 10000000} {incr i} { set o [Object create obj-$i] $o destroy } can it be that you are somewhere building a table (assoc. array) with object names? xotcl has a bunch of compile flags to report memory usage, one can compile tcl with a flag that enables a command for memory checking. -gustaf > > Thanks, > > Ben > > -- > You know you have reached perfection of design not when you have > nothing more to add, but when you have nothing more to take away. > --Antoine de Saint Exupéry > >------------------------------------------------------------------------ > >_______________________________________________ >Xotcl mailing list >Xotcl(a)alice.wu-wien.ac.at >http://alice.wu-wien.ac.at/mailman/listinfo/xotcl > >
