No. I have added this as self-defense of Tramp. The error was triggered, when I have opened a file on a NAS via Tramp. I have mounted the emacs source directory there, and I have tried to open a file in that directory. Due to the existence of .../emacs/.bzr, there was a call (process-file "bzr" nil t nil "status" "--no-classify" "README") bzr is not installed on that machine, so this call failed. The real cause of the problem is a design deficiency, I believe. vc-bzr should check, whether bzr is installed. Unfortunately, we have only `executable-find', which works on the local machine. We would need a counterpart of this function for remote machines, like the pairs `call-process'/`process-file' and `start-process'/`start-file-process'. > Stefan Best regards, Michael. ^ permalink raw reply [flat|nested] 5+ messages in thread

So an error here indicates an error in some code somewhere. In this case, with-demoted-errors is preferable. > The error was triggered, when I have opened a file on a NAS via Tramp. > I have mounted the emacs source directory there, and I have tried to > open a file in that directory. > Due to the existence of .../emacs/.bzr, there was a call > (process-file "bzr" nil t nil "status" "--no-classify" "README") > bzr is not installed on that machine, so this call failed. Sounds like a bug in vc-bzr-register. Could you either try and fix it there (catching the error right there), or file a bug report for it?

It took almost 4 years, but now I've fixed this. >> The error was triggered, when I have opened a file on a NAS via Tramp. >> I have mounted the emacs source directory there, and I have tried to >> open a file in that directory. >> Due to the existence of .../emacs/.bzr, there was a call >> (process-file "bzr" nil t nil "status" "--no-classify" "README") >> bzr is not installed on that machine, so this call failed. > > Sounds like a bug in vc-bzr-register.

I don't remember whether I've filed a bug report, but it is fixed now. > Stefan Best regards, Michael (proud, 'cos I've shortened my todo list). ^ permalink raw reply [flat|nested] 5+ messages in thread
