[ECB-list] Error when activating ECB

[Arne Schmitz]

With the new-cedet branch of ECB I sometimes get the following error when trying to do ecb-activate:

ecb-clean-up-after-activation-failure: ECB 2.40: Errors during the layout setup of ECB. (error-type: file-error, error-data: ("Opening directory" "permission denied" "/home/someuser"))

If I wait for a minute or two and try again, ECB will activate. The directory in question is indeed not readable by me, but I am not even consciously trying to access it.

Best regards,

Arne

Hi

Please, update from repo - I added backtrace generation when error is
caught. When you'll reproduce this error once again, please send
backtrace here

Ok, thank you, although it's not so much useful information... I'll
look (hopefully today) onto error-handling code & will do more changes
there, and will notify you

[Arne Schmitz]

Hi Alex,

did you get any chance to look at this issue? I am getting this error more and more often. Only sometimes I can now activate ECB.

Best regards,

Arne

[Arne Schmitz]

For your information: with only the *scratch* buffer in existence, I get a different error:

ecb-clean-up-after-activation-failure: ECB 2.40: Errors during the layout setup of ECB. (error-type: wrong-type-argument, error-data: (stringp nil))

Regards,

Arne

[Alex Ott]

Hadn't looked, sorry - not so much free time

[Alex Ott]

Can you send me backtrace for this error (enable Debug on Error before
activating ECB)

I have just gotten a new Emacs version at work, and can't reproduce the problem currently anymore! If it comes back, I will do that. But maybe the new Emacs version fixed it!

Best regards,

Arne

I've got the error again. The backtrace I get after toggle-debug-on-error is:
 
Debugger entered--Lisp error: (error "ECB 2.40: Errors during the layout setup of ECB. (error-type: wrong-type-argument, error-data: (stringp nil))")
  signal(error ("ECB 2.40: Errors during the layout setup of ECB. (error-type: wrong-type-argument, error-data: (stringp nil))"))
  error("ECB %s: %s (error-type: %S, error-data: %S)" "2.40" "Errors during the layout setup of ECB." wrong-type-argument (stringp nil))
  ecb-clean-up-after-activation-failure("Errors during the layout setup of ECB." (wrong-type-argument stringp nil))

ok, thank you - I'll try to debug it

[Rob Reid]

I have started getting this error too after a recent reboot. Another user
on the system has their ~/ non world readable, and I guess they didn't
before.

I was able to get around it by switching to a buffer that was *NOT* in
/home, running ecb-activate, and then changing the ecb window layout to
"left11". That layout does not have the directory tree window. I find I
prefer it anyway, but I was surprised that the directory tree window would
care whether directories were readable if I was not trying to read them.

Best regards,

Rob

Hi Rob

Can you check the fresh snapshot - I've checked in the some changes yesterday that should prevent this error...

Thanks, but it didn't work.

The ECB 2.40 version might be wrong, but it is the ecb from the zip file of
https://github.com/alexott/ecb - which is the only ecb I left in my
~/site-lisp/, as ecb-snap. It seems to be finding the new version - C-h f
on ecb-directory-files goes to ~/site-lisp/ecb-common-browser.el, and the
help string says "Wrapper for directory-files that fixes the file name &
catch file errors".

Also, I had to remove the require ecb-autoloads from my ~/.emacs.el. This
is with GNU Emacs 23.1.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.18.9) of
2012-03-01 on c6b18n3.bsys.dev.centos.org (CentOS 6)

Here's the error message:
