Log of failed write by MS-Visio

[Georg Lehner]

Hello!

Following you find a log from a ninefs-session, where i tried to save a diagram opened
in Microsoft-Visio to N:\usr\leg\tmp, N: beeing the mounted drive. ninefs options: -dDU

Visio fails to write the file (with something like: 'could not open the file the way i wanted').
After this, i closed Visio and unmounted N:

At a first glance it appears to me, that the |DesiredAccess and |CreationDisposition are combined
in such a way, that ninefs' _CreateFile is not interpreting as "create" but rather as "open".
The 'CreateFile status = -2' means 'ERROR_FILE_NOT_FOUND'.

Best Regards,

Jorge-Le�n

Hello!

Today i found out, that np_rerror sometimes returns -1 when a file is
not found, where it sould
return 2 instead (NOENT). Patching the cvtError() function in ninefs.c
to return ERROR_FILE_NOT_FOUND
in both cases allows me now to create OpenOffice documents.
The np_rerrror strings differ also:
-1 .. file does not exist
2 .. file not found

I downloaded a Microsoft Visio trial version on my home computer to test
the Visio problem, and can
create visio files with it, however it chokes on some sharing
conflicts... Interestingly, when i want to copy
a 44KB Visio file from the Desktop to the ninefs drive it takes about a
minute (with otherwise very fast
access), and i get also an error message:
- - -
N:\usr\jorge\Drawing1.vsd
This file is open for modifications in another instance of Visio
- - -

A ninefs.c and its binary ninefs4.exe can be found at:

http://www.magma.com.ni/sw/ninefs/

The ninefs.c file does extensive logging in the _CreateFile() function
with the -d flag and is by
default very chatty in the cvtError() funtion.

I'm not surprised. I've been putting off working through the error codes for a while

and I think I really should go and set that right.  Also I havent been using ninefs

too much, so I haven't tripped across some of these issues.  I'll try to set something

up soon to make more use of it locally.  That'll probably inspire me to look at

performance a little, too.

Thanks for the analysis and patches.

N:\usr\jorge\Drawing1.vsd
This file is open for modifications in another instance of Visio

Hmm.. Interesting.  I wonder if other common programs suffer from this as well

Hello!

With the new tracing facilities ninefs5.exe it is possible to look
closer at what Visio wants from "us".

I have copied a working Visio file (Drawing1.vsd) to a ninefs drive,
(re)started a ninefs5 -ddU session
and run 'N:\usr\jorge\Drawing1.vsd'. The resulting trace can be found at:

http://www.magma.com.ni/sw/ninefs/visio.log

In ninefs5.exe i allow _LockFile() and _UnlockFile() to return success
for any input parameter, since
on the contrary Visio stalls for quite some time. The _LockFile()
parameters used by Visio can be
observed in the visio.log file, they seem complete rubbish to me. Maybe
some enlightened beeing
can explain their meaning, tell me they are moot anyways, or correct my
fprintf() format string to show
what is really going on :)

Also i hope, that publishing ninefs5.exe inspires more people to run
tests of commonly used Windows
Software on ninefs. I found it useful to run the following two
commandline variations:

ninefs5 -dUp <password> -u <user> <host> <driveletter>

ninefs5 -ddUp <password> -u <user> <host> <driveletter> 2>ninefs.log

The first for a quick glance, and the second one for heavy duty tracing.
