Description: |
Tcl Version: 8.5a4 OS Version: Windows XP SP2 Once an extension is unloaded with -keeplibrary I'm unable to load the extension again. This happens with any extension, but I'll use the bundled registry one to demonstrate. Actual output: LoadA: registry {registry tcl::tommath Tcl} Unload: {} {tcl::tommath Tcl} LoadB: {} {tcl::tommath Tcl} Expected output: LoadA: registry {registry tcl::tommath Tcl} Unload: {} {tcl::tommath Tcl} LoadB: registry {registry tcl::tommath Tcl} When the load command is invoked afterwards (LoadB), it seems Tcl does not call the package's Init() procedure. | |||

Logged In: YES user_id=1119750 My mistake, this is a duplicate of 1111134. I searched for "-keeplibrary" and no results were returned, so I assumed this issue had never been mentioned. dgp added on 2006-03-23 10:39:44: Logged In: YES user_id=80530 how is this related to 1111134 ? neoxed added on 2006-03-20 12:23:29: Logged In: YES user_id=1119750 After further investigation, the problem occurs at lines ~255-260 in tclLoad.c. The load command will search through a list of loaded packages, and if the package is already loaded it returns. Since the package is unloaded with -keeplibrary, it's entry remains in the package list. neoxed added on 2006-03-17 15:19:59: File Added - 171235: unload.tcl |
