read-only buffer

read-only buffer

[jirka.senkyr]

Hello.
In my emacs when I open a file which under a version control (SVN) the buffer is read-only. I do not want it. It's pretty annoying especially when using tags-query-replace. Then I need to make each buffer that opens by the tags-query-replace command writable by hitting C-x C-q. But by doing so tags-query-replace is terminated and I need to run it again and again and again....

I have searched emacs help and internet but haven't found a clue.

Does anybody know, how can I make emacs to open version controlled files in writable buffer?

Thanks,
Jiri

That's definitely not the standard behavior.  Is it possible that you
don't have write permissions for the files in that SVN checkout?  In
that case, emacs would find the file read-only.

Hi, Tassilo.
I do have a write permissions for these files.
I might have mentioned then I'm using Cygwin under Windows. Don't know if
it's a clue.

Thanks,
Jiri

Ok, too bad.  That would have been a likely cause.

I don't have neither here to test but I guess others would have
complained much earlier if that would always happen.

Did you try opening such a file with "emacs -Q" just to rule out the
problem is caused by your init files or third-party packages?

Which parts are from Cygwin?  Emacs and SVN, only Emacs, only SVN,
something else?

Hi, Tassilo.
When I run emacs with -Q option it does the same, all buffers with SVN
files are read-only by default.

Thanks,
Jiri

Emacs is cygwin, SVN is windows.

OK. It looks like the problem is in mismatch of file permissions between Windows and Cygwin. After I ran chmod +w emacs opens files in writable buffer.

Right, it figures: Cygwin implements Posix permission bits in a way
that native Windows programs (in this case SVN) don't understand, and
vice versa.
