I had mged -c up in valgrind and it didn't squawk about anything when that happened...
starseeker (Dec 19 2020 at 16:15):Could libtermio be out of sync with modern terminals somehow?
Sean (Dec 22 2020 at 21:21):Yep, that looks like the corruption. It wasn't libtermio the last time this happened (last winter), but it could be. It could be lots of things. The thing to do is attach a debugger when it happens, see what's messed up. It usually prints the version info, which is held in global static vars, so that's a strong indication its memory corruption.
starseeker (Jul 24 2023 at 20:22):A quick debugging session suggests that brlcad_ident isn't being called when the version string is appearing in the output.
starseeker (Jul 24 2023 at 20:26):There's an interesting note in src/mged/cmd.c around line 1029 warning that the input string needs to be saved because f_mouse is "notorious for adding things to the input string" and indicating the non-copied input shouldn't be fed to Tcl_Eval... are we perhaps Tcl_Evaling something we shouldn't either here or elsewhere in MGED and getting corrupted input that way?
Sean (Jul 24 2023 at 20:31):What happens if you put “global version” and “set version something” in your .mgedrc? That’ll indicate whether it’s the tcl bar or not.
starseeker (Jul 24 2023 at 22:37):Grr. Now it doesn't want to repeat - the instance of corruption I'm getting now pulled part of a previous command's text in as I middle click pasted, but not the version string specifically:
mged> 1;2A1;2A1;2A1;2A
result: invalid command name "1"
invalid command name "1"
mged> ls
result: LIGHT cone.r/R light.r/R tor.r/R
all.g/ cone.s platform.r/R
box.r/R ellipse.r/R platform.s
box.s ellipse.s tor
LIGHT cone.r/R light.r/R tor.r/R
all.g/ cone.s platform.r/R
box.r/R ellipse.r/R platform.s
box.s ellipse.s tor
mged> ve1;rsion2A1;2A1;2A
result: invalid command name "ve1"
invalid command name "ve1"
(The corrupted 'version' command was generated from a middle-mouse-buttion paste selection that had both a clean 'version' text command and additional lines of text from the history selected, btw) Looks like the previous history text apparently started to get inserted after just two characters of the paste had landed...
Sean (Jul 25 2023 at 22:45):I've seen it be things other than the version string too, which is also why I think version is probably just one of the last commands to get run. (there is a "set version [brlcad_ident "..."]" in the initialization.)
