Re: [Evolution] troublesome cache

[Richard Bown <richard g8jvm com>]

Hi Pete it really is driving me nuts

the offending file is the one with 5050 in the name

richard@richard-Inspiron-3580:~/.cache/evolution/mail$ ls -ls

total 12

4 drwx------ 3 richard richard 4096 Feb  5 08:54 0656774d545ea2bb57c9be746823f7d3f567198c

I can shut down evo , delete that  directory, and as soon as evo is restarted it reappears.

I have tried deleting the account, from within evo

and 

running sudo apt purge evolution

that should remove evo and all its config files, 

then deleted .cache/evolution

but when I re install evo , everything that was deleted just reappeared

Now I suspect that as when a file is deleted the space it used still contains the data, until overwritten

some mechanism may be recovering what was deleted.

there is an ultimate way way of doing it which I dont want to have to get to

My home dir is on a separate partition, last resort would be to back up all the non-hidden files

boot up on the last listed partition which is a very earl version of LM17.3 for apps that still use KDE3

run gparted and format /dev/nvme0n1p2   , the /home directory

But that is last resort., which I dont want to have to do.

There must be a simple way of flushing the cache so it can start as a virgin install

or getting rid of that mail directory.

apologies for using html, the reason was line wrapping

There is a backup copy of the cache that evo uses to restore the cache

should it be deleted.

No, because it's not a cache then.  The cache just contains local

copies of data downloaded from the server (plus a few oddities).

I need to delete that back up so the cache can be flushed.

There is nothing in the help file anywhere , thats why I'm asking

There are corrupted files in the cache and they need to be removed

That cache needs to flushed

Deleting .cache/evolution is *the* way to do it - but make sure all

evolution components are not running before you do it.

Certainly evolution will create the cache when it starts, but that's

not copied from anywhere. What I suspect you are seeing is information

that isn't stored in the cache. Have you tried simply deleting the

account in evolution and re-creating it?  If it's 7 years since you've

used the account data, then it definitely needs to be deleted and

reconfigured - removing the cache will not do that.
