Mongrel users - Nov 2007 - file access with mongrel running as windows service

i have an archive of documents (word, excel, jpeg, png, gif...)  
residing on a network share that is accessed via send_file.

when running mongrel on the command line the files are properly  
delivered.
with mongrel running as a service they don''t.

now normally i would think that should be fixable by configuring the  
service to run under a user that can read the files....

but i''ve already tried that without success.

running the service as system or administrator or the user i''m using  
for development (the same user i run the mongrel on command line) does  
_NOT_ help. so i can''t figure out how to get this to work.

development or production mode also doesn''t make a difference.

from what i''ve seen so far this generally applies to any File IO
access.

could this be a bug in the mongrel service implementation?

Try running "net use" inside the process to see if the network share
is
mounted at all.  This sounds like the typical Windows/web problem where the
operator assumes that everybody sees the same shares that she sees in her
session.  In reality, network shares are mounted per login session.  Two
users can be logged in on the the same Windows server and have different
shares available on Z:, which is clever, but also sort of confusing.  What
is even more confusing is that you may be logged on as "user1" and
have
something mapped to Z:, but the service running as user1 has nothing on Z: ?
it needs to create its own mappings.

Let us know if this helps.

Unless you''re running the mongrel service as the same user, the mapped
network drives are not available.

Either you use the full network path (\\SERVER\PATH) or you run the
service as the user that defines the mapped network drives.

You will need to access the Services definition and under properties
select Run as user. You will need to provide the password too. (all
this under administrative tools, things may vary between windows
versions).

No, I''m saying that you need to run your service under a user account
that defines those mapped network drives. Since network mappings (Z:,
W:, etc) are dependent of the user, needs to be run as that particular
user.

You need to change those settings for that particular service under
the "Services" manager in Administrative Tools (control panel).

I''m having problems understanding your english.

Mapped network drives do not start with //, they are normal network letters:

C:\Users\Luis>net view
Server Name            Remark

-------------------------------------------------------------------------------
\\KEORE

C:\Users\Luis>net view \\KEORE
Shared resources at \\KEORE

Share name  Type  Used as  Comment
-------------------------------------------------------------------------------
Users       Disk

C:\Users\Luis>net use * \\KEORE\Users
Drive Z: is now connected to \\KEORE\Users.

The command completed successfully.

C:\Users\Luis>irb

It is clear I don''t have permission to do that, but:

irb(main):003:0> FileUtils.touch "Z://Luis/foo.txt"
=> ["Z://Luis/foo.txt"]

I do.

Also:

irb(main):004:0> FileUtils.touch "//Z://Luis/bar.txt"

`touch''
        from (irb):4

it is clear that // should not prepend the drive letter, but instead:

irb(main):005:0> FileUtils.touch "//KEORE/Users/Luis/bar.txt"
=> ["//KEORE/Users/Luis/bar.txt"]

I hope this explains a bit better what I''m talking about.

I have no idea where are you receiving the ''invalid argument''
error.

It is extrematelly important than when you report an error, provide
enough details and precision about it, more precisely, the full error
messages and backtraces.

We can''t replicate or provide you help if you skim it and provide
vague information.

Help us help you.
