Hi,
aha, I see, it's only in the `evolution --help`. I may add it, I guess.
Thanks and bye,

Hi,
out of interest, did you want to delete it from the local cache, while
it was not shown in the GUI at all (even with View->Show Deleted/Junk
Messages checked)? The file will be removed from the local cache after
some time period, depending on your local cache policy from the
Receiving Options tab, but, for deleted/moved messages, the local cache
message should be removed/moved as well.

In this particular case (and no where else), that being cached mail
messages, those can be removed also when having Evolution running, even
when viewing the message in the Preview panel. The next time the
message is selected it is downloaded again (by a very simple logic:
cache file doesn't contain requested file => download it first).

Nonetheless, I agree it's always safer to close the application, which
can access the files, to avoid unexpected issues.
Bye,
Milan

$ /usr/libexec/evolution/killev

or just:

$ pkill evolution
(after exiting the main GUI)

Yeah, right. I know for a fact that these Evolution data server bits
will access data when you least expect it. I just haven't looked
recently to see what particular data is used.

Then I'm even more surprised that you don't seem to know the difference
between Evolution and Evolution-Data-Server. The original topic was
about mail cache and making sure Evolution is not running, while you
posted about unrelated Evolution-Data-Server daemons (plus Evolution-
Data-Server has no background daemons for mail parts anyway, AFAIK).

I think I understood and acceptably summarized the problem in the
previous paragraph of this message. :)

That is quite a caveat to add on there.

Evolution has so many small daemon pieces that it is almost impossible
to tell if it is "running" and nearly impossible to prevent it from running.

No. It's easily possible not to run Evolution: Just don't start it.


Yeah, right. I know for a fact that these Evolution data server bits

You seem to mix up two very different things:
Evolution and evolution-data-server.

I don't use Evolution on this Ubuntu machine. I've never configured it.

Then I wonder what brings you to this mailing list...


I have used Evolution in the past. I've even done development on it. 
Mostly bug fixes and attempts at bug fixes. Trying to make Evolution 
work for a linux-kernel virtual folder without becoming completely 
confused or crashing with a 3 GB memory leak, for example.


Or trying to batch edit a bunch of downloaded email using Perl scripts.



And yet there are four /usr/libexec/evolution-* processes running. If
you kill one DBUS semi-randomly restarts it.

First there were "so many small daemon pieces". Now there are only four?
I can't make much sense out of this conversation so far.


Yeah I think I recognize your name from past conversations and you never 
have been willing to understand other people's problems.


If you actually know for a fact that the cache files will only by 
touched by the Evolution GUI client then just say so.

I don't know if those cache files are ever touched by 
evolution-data-server but it is something to keep in mind.

It's always safe to remove cached files. Evo will just recreate them if
needed. Just be sure that Evo isn't running when you do it.

Please explain what you mean by this. Are you trying to do this from
within Evo or from the command line or file manager? What happens if
you try to delete the folder?

[Evolution] Safety of removing .cache files

2020-12-30 Thread Dr. John H. Lauterbach

Mail/cur/09/419787 ?

Above directory refers to the "Bulk Mail" account on an IMAP email account from 
bellsouth.net.  I
cannot delete such a folder on my evolution email account.  My evolution 
version is 3.38.1-1.

I have other PC's (Win 10 -- Outlook 365) with the same email account  and 
folders and have no
problem deleting undesired email in the Bulk Mail account.

Thank you,

John
