[Bug 653623] Re: gvfs-gphoto2 eating 100% CPU and no I/O operations

2011-01-25 Thread Carl Friis-Hansen
This is not only 100% CPU usage, it is also a memory problem. It looks like the 
copy operation wants to acquire the whole file in memory during the copy. This 
is not a serous problem for normal pictures under 20MB, but I just gave up 
copying a 2GB MOV file from a Canon 7D to Ubuntus 10.04 using USB cable. The 
following path was shown in Nautilus:
gphoto2://[usb:001,006]/DCIM/100EOS7D

Related to this bug is that the limitation in when to show preview. When
you disable preview for files over 50MB, this setting is ignores for
files on the digi cam. This is a problem because the transfer rate is
not fast, it takes 100% CPU and takes just as much memory as the size of
the file processed for preview. The only way I found to avoid this, is
to disable preview of other media altogether.

Workaround appears to be to take out the CF anf stuff it directly into
the computer.

If I use the GUI help on Ubuntu 10.04 (upgrade to), then you see the  
problem in the attached image.

[Bug 13983] Re: Evolution virtual trash / "real" trash on IMAP server

2009-12-01 Thread Carl Friis-Hansen
A note about the directory structure.
As you can see on the picture, the INBOX.Trash is not iconized as trash, but is 
actually showing the contents of the trash folder on the server.  The Trash 
folder on the other hand, is icinized as trash, but is outside the structure of 
the INBOX and is not represented on the server and is the folder where Evu. 
presents the deleted mail.

Delete in non Evu. client:
INBOX.friends --->  INBOX.Trash

Delete in Evu. client:
INBOX.friends --->  local-machine.Trash

[Bug 13983] Re: Evolution virtual trash / "real" trash on IMAP server

2009-12-01 Thread Carl Friis-Hansen
It is possible that I have misunderstood how Evu works, but one thing is
for certain, you misunderstood the main point and I will tell this from
a more practical point of view, something reproductive.  If anyone wants
to try it out, I will gladly open an email account just for the
research, if we kan find some way of getting in direct contact with each
other, like cfriisha at jabber dot org.

Main point:  After deleting mail in a sub folder, this mail appears in
the Evu. Trash folder and not in the server side Trash folder.

Behavior: Of all the mail clients I have used, only Evu. does deletion
tis way.

Reproduction scenario:
IMAP server = courier on Ubuntu 9.04
IMAP client = Evolution 2.28.1 on Ubuntu 9.10
IMAP account = INBOX, INBOX.Drafts, INBOX.Sent, INBOX.Trash, INBOX.friends

There are a lot more folders on the actual account, but the first four
are the standard ones and then I included one of my extra folders.

The steps:
I receive a mail in my INBOX from f...@example.com which I read, close and drag 
to the INBOX.friends folder.
Later I highlight the email from f...@example.com in the INBOX.friends and hit 
the Del key.

The actual result:
f...@example.com does not appear in INBOX.Trash but rather in Trash. 

My problem with this is that the folder Trash is not anywhere to find on
the server, which suggests to me that Trash is a local folder.  If I
want to undelete f...@example.com I will have to do it from that
particular Evu. client.

The expected result:  (As with any other client I have ever tried)
f...@example.com appear in INBOX.Trash.

and I can later recover that email from any client, anywhere, at any
time.

Why the difference:
>From what I see Sebastien and Paul write, it appears that Evu. really does 
>mark the mail on the server as deleted, so could it be that things doesn't 
>work for me and the OP because of strange behavior of the Courier IMAP server, 
>which I would have thought was a rather common server?

[Bug 13983] Re: Evolution virtual trash / "real" trash on IMAP server

2009-11-24 Thread Carl Friis-Hansen
For Delete message Evolution is using:
  IMAPv4 EXPUNGE Command
instead of
  \Deleted flag set

For search message Evolution is using:
  fetch all mail, inclusive body where apply, and do a local search (The POP3 
way)
instead of
  IMAPv4 SEARCH Command

Here is a fresh example why it is a problem:
--
Just lost over 800 deleted emails.  I had borrowed a laptop with Ubuntu 9.10, 
configured my usual IMAP email account in Evolution.  There where practical 
reasons for me not to use my Squirrel mail to the same IMAP account.
After deleting some 800 messages and giving the laptop back, I found that the 
deleted messages where nowhere on the IMAP server.
--

Using many different clients over the last 10 years, this is the first time I 
encounter an IMAP client that totally missed the Idea with Internet Message 
Access Protocol.  Evolution should display a clear warning, that the 
application does not follow the standard of the IMAP protocol or they should 
correct the client ASAP.
This disrespect has gone on since 2005 and has been deemed wishful thinking by 
the otherwise so great Evolution team.

We can all have different ideas about how an email client should work,
but to ignore the whole purpose of the IMAP protocol is not the best way
and the proprietary delete and search implementation is also a security
concern and massive misuse of Internet bandwidth.

In todays IMAP the "Deleted" flag and the Search command are is to be used.
Flags defined in the IMAP4 protocol serves to tell weather an email is deleted 
or not.  The IMAP server will take care of presenting a deleted email as being 
in the Trash folder and the server will normally also take care of expunging 
deleted emails after for example 7 days or so.  These flags are stored on the 
server, so different clients accessing the same mailbox at different times can 
detect state changes made by other clients.

Sadly it is the same issue with *Server-side searches* that is *not*
offered by Evolution.  Some of us have more that 10,000 emails and need
at times to search through the text body of *all* the messages.  Such a
search takes  about 5 seconds when issuing a Server-side search and the
only download are the headers of the result - perfect.  Such a search is
impossible in Evolution, which only provide a locally implemented
search.  Theoretically one could wait a day or too for Evolution to
download all the email bodies, but how complicated can it be to
implement a real Server-side search?

Most other IMAP clients use the correct way of Deleting (and Searching).
I think (guess) that the problem, seen from Evolutions' standpoint, is
that everything is done correctly with respect to POP3 and that the
different architecture need for full blown IMAP4rev1 functionality is
problematic.

So my recommendations is to clearly state, in the account definition, something 
like this:
Server type:IMAP (Partly implemented)   
Description:For reading and storing mail on IMAP servers. Delete and Search 
act in POP3 style.

Until such time the RFC 3501 is implemented regarding Delete and Search.

[Bug 50318] Re: manpage rendered wrong

2008-08-13 Thread Carl Friis-Hansen
yelp man:convert is not rendered so nicely. All the options are listed in one 
long stream, thus no line breaks.
A snip:
Image Settings:
  -adjoin  join images into a single multi-image file
  -affine matrix   affine transform matrix
  -antialias   remove pixel-aliasing
  -authenticate value  decrypt image with this password
which looks almost okay here, but not in yelp.
