Indeed it doesn't, so the safe way is to lock/unlock files that might
be accessable over a network. There is no problem with
locking/unlocking files if they are only accessed on a stand-alone PC,
and there is no delay (well, maybe a few nanoseconds), so why risk
data corruption?

 Therefore the (unsatisfying and to what I've read about it not 100%
 working) The Bat! Server mode is implemented. This way it knows
 about sharing and can handle concurrent accesses.

TB's server mode has something to do with a center downloading the
mail and the clients only connecting to the center rather than to the
internet. Of course, they also share files (I don't even know whether
they are locked, but they should be). But I am not talking about the
server mode.

Hello Jernejcic,

On Monday, March 10, 2003 at 8:17:06 PM you [JA]wrote (at least in
part):

P No ... but were in The Bat! you've seen shared folders?

JA what a sophisticated question.

That's what I'm known for ;-)

JA I am talking abount the folders, that are called common folders in
JA The Bat! .

Not just called ... _named_ :-) A sophisticated, but important,
difference.

JA imho, to use common folders could sometimes, in very special
JA situations, mean, that they are shared - got it?

As every other folder could, in very special situations of course, be
shared. They're named Common folders not because the can be shared
without hassle between different people, but only because they don't
belong to an account.
Sharing folders requires lock and sync actions being implemented.
As these common folders are only belonging to a virtual but
non-existent account I don't think special file handling, taking care
of locking and syncing, was implemented. So how should they update
automatically? The Bat!s speed comes from semi intelligent use of
indices and keep in memory as long as you can. If The Bat! would
need to lock and sync every operation if would _slow down_
significantly. So your best bet is: Create a Wishlist item (follow the
URL in list footer) for _Shared folders_. RIT could this way create a
special kind of folders, marked as sharable which makes use of lock
and sync (with all slowing down effects), while all other folders are
unaffected and kept fast.
Current implementation is only designed to be thread-safe, not
share-safe, you're expecting something that ain't programmed. Like if
you'd expect a Fiat Uno being able to drag your mobile home, to spare
the costs of a truck :-)

Well, it's been a while since I programmed on networks. On a 40-user
network, all data files were shared. It didn't slow down the system to
just lock and, after successfull transaction, release the files. Of
course, if one user opened the file, nobody else could access it, but
the data integrity was preserved; so if user's access to a file is the
delay you are talking about, there is certainly a delay, but it is
necessary for data integrity.

You could refine it by limiting the lock to write access, so if any
user was only reading the file, others would still have access - to
both read and write. If someone else writes to the file, you could
still not update the file on the user's screen who only reads it,
until the next time he opens it. In small networks, this could be
sufficient. Otherwise, if the client has to check regularly for
updates, I agree it may slow down the program.

In any case, I think the current version of not locking files at all
is dangerous if two users write to it at the same time. Any
application that is networkable should you file locks. This is true
for message files as well as for address books.

Sure - we've been round about this before.

Works fine for me with about a dozen users. But I thought your last

Re: Shared Folders

2000-07-20 Thread Ming-Li

Hi Thomas,

 I am the one still using an IMAP server. (It is still working
 fine). Is it possible to set something up in order to access
 shared folders (on the IMAP server its no problem) or to have
 incoming mails visualized to more then on users? (that do not have
 necessarily configured the same pop or imap user)

Ehhh, I have no experience with IMAP at all, and frankly I can't
figure out what your questions mean. So pardon me to try the most
obvious answer: have you tried the Sorting Office/Filters?

I know this isn't any real help. It serves more as a reminder to the
veterans here (who're probably consumed by the recent S/MIME beta
issues on another list) that there's a unanswered question from a
(presumed) new user here.

TM (on the IMAP server its no problem) or to have incoming mails

If I catch your drift, I would imagine that such a configuration would
be only possible from the IMAP server itself, that is, show these two
different groups of email (public-to-everyone and private-for-user,
say) to each user as one "block" of messages?  Dunno about IMAP
myself, but this sounds like what you're trying to do (in which case
you need to ask on an IMAP list!).
