[horde] [PATCH] Bug in lib/VFS/ssh2.php and ingo/lib/Driver/vfs.php?

[Lawrence Stewart]

Hi All,

Updating and reading of my .procmailrc file via Ingo stopped working 
after a recent system update to Horde 3.3.5/Ingo 1.2.2. After realising 
the "vfs_path" param was now required in Ingo's config/backends.php file 
(used to work without it), there were still issues retrieving the active 
script.

I tracked the problem to the 2 files mentioned in the subject. The 
attached "ingo_fixread.diff" patch updates the vfs->read() call Ingo 
makes to try and retrieve the active script file. The patch makes the 
read() call pass parameters in the way the VFS code seems to expect them 
(gleaned from observing how the write code path works). I believe things 
may work without this patch but it seems to be more correct this way to me.

The attached "horde_sshfilesizefix.diff" patch addresses the fact that 
even though the active script file was being successfully pulled via ssh 
and created as a local tmpfile, the filesize() check on the local 
tmpfile would always return 0, even though the tmpfile actually 
contained data (verified by hacking source code to dump contents of 
tmpfile into a separate file). It seems some prior calls to PHP 
functions that call the underlying OS stat() routine were caching the 
filesize at 0 (before it had been populated), and this in turn meant the 
script would not be successfully displayed to the user. Clearing the 
stat cache fully mitigates the issue for me.

With these two patches applied, everything is peachy again. For 
posterity's sake, my working Ingo backends.php config is included at the 
end of the email.

Cheers,
Lawrence
