@Josua, agreed and as mentioned on comment #13 the package has been made to use tcl again now, in an ideal world we would prefer to have one less interpreter on the default installation to maintain but in practice the cost is low so it will do -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: Device validation failing when connected to an usb hub Status in usb-modeswitch package in Ubuntu: Fix Released Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop.

Sebastien, I understand your concerns with regard to jimtcl. However, the tcl package seems to be well maintained, with very few bugs (2) in the current version, one of low urgency and one undecided. Anyway, it's not my decision to make obviously.

@Jakub, pulling it an extra interpreter in a stable update is probably not something we want to do so we are going to either fix the issue in the C code or let <= focal versions have issues in some cases. I do agree that starting doing changes to the logic might be something we want to avoid, there is probably an easier way to restore the previous behaviour but in a way that avoid the segfault right? Also not that Jim is currently in Universe and not something Canonical has commited to maintain, which is why we are using tcl (which is in Ubuntu main) @Josua, the problem there isn't the language or startup performance but having to maintain one extra language/interpreter for us (Canonical/Ubuntu), it means we have to keep someone on team familiar with tcl and to commit to fix any security problem find in the tclsh (or jimtcl if we decide to promote this one) which is adding maintenance load of a small team already having lot to do -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: Device validation failing when connected to an usb hub Status in usb-modeswitch package in Ubuntu: Fix Released Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop.

[Desktop-packages] [Bug 1866926] Re: Device validation failing when connected to an usb hub
Let me just explain shortly why I'm sticking with Tcl for the dispatcher. That script language is perfectly fitted for string and file parsing. At the same time, it's much better human-readable than a Bash or Perl script. I had people adding fixes to the wrapper script who weren't even familiar with the language. Execution time is not really relevant regarding the mode-switching process, because its duration predominantly depends on the device's internal workings until it 'reappears' in the new mode. Both the bare interpreter tclsh *and* the 'pocket version' (jimtcl) have everything on board for the task. No loading of additional extensions or modules required. Besides, I somehow can't warm up to Python but that's my personal issue :-) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: Device validation failing when connected to an usb hub Status in usb-modeswitch package in Ubuntu: Fix Released Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop.

Hmmm, the Ubuntu version does depend on Tcl.

[Desktop-packages] [Bug 1866926] Re: Device validation failing when connected to an usb hub
I'm starting to feel that trying to fix the C rewrite is futile. On line 392 of usb_modeswitch_dispatcher.c, the iface variable is overwritten. Unfortunately the value being assigned is not an interface number, it is rather a USB class number. Fixing this might help with some part of this, but it also might break something else. I was also trying to map between the C rewrite and the 2.2.5 version of the tcl script (as stated in the header of the C version), but it seems that there are functional differences (for example the if_chk mode seems to trigger on different ocassions). I'd vote for going with the Tcl version for Focal as well (I'm ignoring any existing SRU rules through). The dependency isn't a full Tcl interpreter, only a small library-based variant of it called Jim (http://jim.tcl.tk/index.html/doc/www/www/index.html). According to the package description, the library size is only 100-200 kB, which seems negligible compared to the current ISO sizes. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: Device validation failing when connected to an usb hub Status in usb-modeswitch package in Ubuntu: Fix Released Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop.
