Tasks with lots of logbook entries are very slow

Tasks with lots of logbook entries are very slow

[Pere Quintana Seguí]

I log most of my work with org-mode. Some of my tasks are repetitive,
this is, I do them weekly or daily (i.e. empty mail inbox). After many
years, the logs are very long. As a consequence, marking these tasks as
done is *very* slow.

Is there a workaround that does not involver deleting the logs?

Example:

**** PNDT Processar la bústia d'entrada
SCHEDULED: <2014-03-25 dt ++1d>
:LOGBOOK:
CLOCK: [2014-03-25 dt 15:31]
- State "DONE"       from "PNDT"       [2014-03-25 dt 15:20]
CLOCK: [2014-03-24 dl 13:21]--[2014-03-24 dl 13:36] =>  0:15
- State "DONE"       from "PNDT"       [2014-03-21 dv 16:18]
CLOCK: [2014-03-21 dv 15:42]--[2014-03-21 dv 16:18] =>  0:36
- State "DONE"       from "PNDT"       [2014-03-20 dj 16:25]

(very long list with log entries since 2009).
:END:

I use org-mode 7.8.11 with Emacs 23.4.1.

Thanks,

Archiving?

I've long resorted to using two drawers back-to-back:

:LOGBOOK:
 …stuff…
:END:
:CLOSED:
 …old stuff…
:END:

Now whenever you need to shorten the logbook drawer, just move the

:END:
:CLOSED:

up by however many lines you think it should.

Achim.

No, archiving would'nt work, as I need the task every day.

Thanks for the tip.

That seems to be the most straightforward solution. I'll do that.

Maybe org-mode could do this automatically. A variable would determine
when log entries should be archived in the second drawer.

I would write a patch if I could program in elisp, but I can't. :'(

Thanks,

Pere

Perhaps this will help:

Standard method for log maintenance outside of org is to rotate logs into  
archive. The current log is only for the current day (or month, week, or  
year). Other criteria, such as log size, can be used to trigger rotation.  
Rotation cuts off the current log, archives it, possibly deletes truly  
ancient logs, and starts a new current log. Look up the Linux logrotate  
command for further info. Here's one description:

Thanks for this.  Very simple yet elegant solution.

I didn't understand your message. I thought you meant archiving the
task, but in fact you meant archiving the logs. That's what I've done.

thanks :-)

The solution has been configuring org-drawers to create a new drawer
called :LOGBOOKARCHIVE" I will put the old logs there, as Achim Gratza
suggested.

Thanks for your tips,

Pere

Take a look at the senders: *I* did mean archiving the task, and
*Peter* meant archiving the logs.
