Even if we have to ask bash for CWD (pwd) when possible it still could be done isn't it? Are you sure it can't be implemented reliably? > - this is fixing the problem at the wrong place, aka a workaround. there > is no way in hell that simple processing of a string with a few tens > of utf8 characters could legitimately require billions of cpu cycles. > my suspicion is that some utterly inefficient shell functions are > being invoked via $PS1 or so - that would also explain why there are > problems reproducing it. First of all there is no problem reproducing it with bash subshell. I clearly described how. It's not "few tens" but rather a several hundred utf8 characters we're pushing to bash every time we change directory. Even though travelling through deep long trees may become very uncomfortable comparing to "-u" mode it wouldn't be so bad if it were merely an inconvenience of slowness. To me much bigger problem is that MC hangs or crashes in this situation. If the problem is due to bash limitation for max path length then we have either legitimate case for workaround or a bug to file against bash. What do you think would be the best to do about it?
