Re: [Evolution] Integration with syncevolution

[Hamzeh Nasajpour]

Hi Milan,

Thank you for your quick reply.

In fact, I want to sync my online contacts (ex: Gmail contacts or ...) to 
local. Then I want to access to the local store for add/remove/edit/get 
contacts in local and again sync them. I need to do these acts 
(add/remove/edit/get) in my C++ applications.

So my components:
* syncevolution for syncing the remote data to the local store
* A middle layer for access to the local store (ex: read/write contacts)
* C++ Applications: they have access via this middle layer. 

And now: what's the middle layer? evolution-data-service? `libsyncevolution`? 
or any other library for access to local store?

Regards.
Hamzeh

Hi,
what do you mean with 'integrate', please? That's important, because
syncevolution synchronizes remote data to local store, which is way
different from accessing the data it synchronized.

> Is there any document about them? How to? Where? Example? 

Again, it depends on your use case. What kind of data do you want to
access? Being it calendar related or address book related? Apart of
reading developer documentation for EBookClient and/or ECalClient, you
may find these links eventually helpful too:

Hi,
the above means that the IMAPx told the server to move message with UID
969 to the Archiv folder and the server confirmed the move, telling
that the added message in the Archiv folder has UID 21295 there.

This is downloading message with UID 970, which means it's a new
message (the previous was 969). I do not see anything in the log
snippet what Evolution would do to move the message back (supposing you
did not remove that part), thus it's something else returning the
message back to the original folder. Could it be any (server side)
filters do that? Or maybe filters from another client, in case you
access the account from multiple clients.

If you cannot find anything, then I'd ask the server admins. They might
be able to explain this. I do not see any faulty thing from the log
snippet.
Bye,
Milan

Thanks for the detailed answer!

I did as you told.

* select message, click archive.
evolution tells me this:

{now the message is printed that I am trying to archive}

Re-selecting the folder makes the message to show up again.

Fine. It means that the message is either copied & deleted or straight
moved to the other folder, depending whether the server supports the
MOVE extension.

Is the message stored both in the archive folder and in the source
folder after it re-appears, or it's not in the archive folder at all?
Some servers (notably Gmail) have pretty aggressive "de-duplication",
based on the Message-ID header, not allowing to store the same message
(well, not really the same, just two messages with the same Message-ID)
in two folders, though I doubt it has any impact here.

You can see what is happening in the background when you run Evolution
from a terminal like this:

   $ CAMEL_DEBUG=imapx:io evolution

It'll print raw communication between the server and the client for all
your IMAP accounts. It's not suitable to be shared in public, due to it
containing a lot of private information, but you can check whether the
message had been copied to the archive folder by searching for the
archive folder name in the log (or for UID COPY/UID MOVE, which should
mention the archive folder name). You can also add "UID" column into
the message list [1] and check whether the UID of the message changed
or not. You can search the captured log for the UID to see what had
been done with it (if I recall correctly, multiple folders can have the
same UID, thus it can be tricky). The log itself can be confusing, I
just mention it as a way to see what is done in the background, between
the Evolution and the server.

Re: [Evolution] Cannot Archive Messages Keep Showing Up

[Alexander Kerner via evolution-list]

Hi,
many thanks for the fast reply!

* Version is 3.34.1-2.
* Yes, I mean the "Archive" button, and I configured also a folder for
that. "normally/ mostly" it works well and messages are moved to the folder.
* The archive folder and the source folder (subfolder of Inbox) are both on
the same IMAP server.

I just ran evolution from the terminal and was able to reproduce the error
but no such messages printed to the terminal.

Best,
Alex

Hi,
let me start with some basic questions:

What is your Evolution version, please?

With Archive, I suppose you mean Message->Archive feature, right?

I suppose you've set the messages to be moved to some folder.

What is the account type you archive messages from?

What is the account type you archive messages to?

Could you try to run Evolution from a terminal, to see whether any
error message is shown there, please? I guess there would not be much
related shown, unless a big failure would happen.

Bye,
Milan

[Evolution] Cannot Archive Messages Keep Showing Up

[Alexander Kerner via evolution-list]

Hi all,

I have a problem properly archiving messages. Some are "resistent" to this
operation and keep showing up.
At first, I thought this is related to the "group by thread" feature, but
also when I disable this, some messages fail to archive.
Anyone can help?

Thanks!

I would start by looking at the Folks library/API - which is what GNOME
Contacts uses

[Evolution] Basically question

[Hamzeh Nasajpour]

Hi guys,

I have a requirement like this:
* There are some applications (developed by myself) that need to store/retrieve 
the contacts.
* I need to sync these contacts with my online accounts, for example, Gmail or 
...
* I also should access to them locally as offline.

So I think `syncevolution` is a good solution for me. I can set-up it on my 
system for syncing the local DB with Gmail. But I want to know how can I 
interact with local DB for read/write/modify the contacts on my device. In 
fact, my applications should have access to DB for read/write/modify. Should I 
use the `evolution-data-server` or `libsyncevolution`? Which is better? or any 
help on this issue. Is there any document about this issue?

Regards,
Hamzeh
