Write with sudo not taking place with sudo:*

[ronin13]

http://sprunge.us/IIDa is the output of :verbose autocmd BufWriteCmd

http://sprunge.us/jccZ is the output of :verbose autocmd FileWriteCmd

For instance for

vim sudo:/etc/rc.conf

while writing I get

File permissions of "rc.conf" are read-only.                                                                                                                                                                                                                                      
It may still be possible to write it.                                                                                                                                                                                                                                             
Do you wish to try?

How do you write the file? What are the permissions of the file?

I can't reproduce the issue currently.

[ronin13]

I am writing the file with regular :w

Shouldn't this autocmd --

au BufWriteCmd,FileWriteCmd sudo:/*,sudo:* SudoWrite <afile>   

-- being working ?

However, when I do :doautocmd Sudo FileWriteCmd

it says 'no matching autocommands'

Interestingly, SudoRead autocmd seems to be working fine (tested on a 0600 file)

Also, manually calling SudoWrite works but autocmd is the issue.

It looks like vim doesn't apply sudo:* match for the write autocmd

Is there a reason, you need to do the :doautocmd instead of simply using
:SudoWrite?

Yes, I did doautocmd to test the autocmd functionality (which is
the main issue of this bug).

I will investigate more and let you know. Also, I tested this
latest vim built from git and it is same.

Christian

ok, this happens, because the plugin removes the sudo:// protocoll handler when reading files. Therefore the pattern from the autocommand does not match anymore and writing won't happen. However, the last commit I pushed, should make it possible.

Thanks for looking into it and fixing it. I will pull, test it and let

you know.

I pulled and used it, however it was still failing for me in something like -- vim sudo:/etc/wgetrc (full path)

Then I noticed that code is looking for sudo:// whereas the autocmd is looking for sudo:/* and sudo:*

So I modified the code to following and it works fine for me now:
