** About

Pimki is my modified Instiki[1], aimed at being a Personal Information
Manager. Current version is based on latest Instiki (0.9.2).

There are some features added to Instiki, features that only make sense
when you view it as a personal application and not as a group oriented
application. Some Instiki features were suppressed. See below for a
full list.

Please feel free to try it to organize your thoughts, email me if you
have any problems (assaph at gmail). Get it at:

http://pimki.rubyforge.org/

** Features

Besides all the regular Instiki goodness, Pimki adds:

* Mind Map: a graph of wiki connections (made with GraphViz).
All graphs can be laid-out with the 4 GraphViz engines. Graph
contents can be arranged as:
o Page → linked pages
o Authors → pages
o Categories → pages
Requires that GraphViz be installed and on the PATH to be
enabled.
* Bliki: a blog integrated with the wiki. Blog entries are simply
wiki-pages in a special space. Can link from an entry to wiki
pages.
* Todo Items & List:
o ‘todo:’ items are highlighted on each page.
o Added a capacity to pull and list todo items from all
pages.
o On main list, items are highlighted & sorted according to date
(if there is one).
o Todo items can have (multiple) context and the display can be fltered
based on that context.
* Added capacity to delete & rename pages through
the ‘All Pages’ list.
* Added Left-Side Menu. Content options are:
o Only pages that reference other pages (default)
o All pages: by name
o All pages: recently revised
o All pages: recently visited
o All pages: most often visited
o User definable wiki-text
* Expanded Search:
o Search also tries to match the page names (not just
contents).
o Now showing part of sentence around match in search-results
page.
* Changed the nav-bar: added links to the Mind Map, Bliki and ToDo.
Moved less relevant links to the bottom of Home Page: RSS,
authors
and export.

** Installation

Download it from the RubyForge project page or go the gem way and
simply run:
gem install pimki

To enable the Mind Map feature, GraphViz[2] must be installed and the
bin directory on the system path.

Run it with the command 'pimki' or install it as a service (see home
page for details).

Hi Assaph,

I've just downloaded Pimki 1.4 (the tgz, not gem or anything). I was using
1.2 and was pretty happy with it.

I guessed that simply copying the "storage" directory from the old
"installation" would work, but it seems not. I can view content, but it seems
they're all old versions of the pages. Any idea?

Regards,

 

[Assaph Mehr]

Copying the storage directory should work (specifically, the <port>
directory within the storage, e.g. 2500).

There should be two sets of files: snapshots and command_logs (which
are incremental changes from the latest snapshot). Make sure you got
all files.
Is it possible that you've grabbed an old directory? or that perhaps
the latest snapshot/command_log file was open by a running instance of
pimki when you copied and wasn't copied properly?

HTH,
Assaph

Hi Assaph,

Thanks for the quick reply.

Copying the storage directory should work (specifically, the <port>
directory within the storage, e.g. 2500).

Yes, I did just that.

There should be two sets of files: snapshots and command_logs (which
are incremental changes from the latest snapshot). Make sure you got
all files.

No snapshots? After that, I did:

zoso@velutha:~/src/pimki-1.4.092$ mv storage{,~}

---------------------------------- >8 ----------------------------------

Is it possible that you've grabbed an old directory?

Hmmm... I don't think so, I only have one pimki directory and no backups,
AFAIK...

or that perhaps
the latest snapshot/command_log file was open by a running instance of
pimki when you copied and wasn't copied properly?

Yes, I thought that, but killed pimki, tried to copy again and didn't work
either :-? BTW, the HomePage version was from December 10th, and I have
updated almost daily for the last several weeks.

Oh, and I forgot to say that I get some errors at startup, I don't know if
it can be related:

After killing the pimki (1.2) process:

z...@velutha:~/src/pimki-1.2.092$ ls -a storage/2500/
total 568
[snip]

No snapshots? After that, I did:

Indeed strange. Has the process been running without interruptions for
several days? It should generate one snapshot per day (after each 24
hours of operation).

Looks like you have the inceremental command_logs, but it only picks up
the first, not all of them. I'll look into it.
Maybe someone who knows madeleine listens in and can help me with
pointers? much appreciated

as for the errors - they're all OK.
- You don't have rubygems, so that's the first error message. It'll
pick the required libraries from the pimki/libraries directory.
- The pdf stuff is from pdflatex which is used in exporting.
- The last 3 errors are caused by somehow reloading the wiki.rb file
twice. I'll get rid of them as soon as I find where it's happening
Cheers,
Assaph

I am getting this

Internal Server Error
undefined method `revisions' for "":WEBrick::HTTPUtils::FormData
WEBrick/1.3.1 (Ruby/1.8.2/2004-11-03) at localhost:2500

My storage directory contains both commands and snapshot files.

Any hints?

Thanks

Oooh... that's the problem, then, I guess I only have it up and

You can change the time between snapshots. I will try to make this a
configurable property, but for the time being you can edit
pimki/libraries/madeleine_service.rb and change SNAPSHOT_INTERVAL to
each hour. You will need to restart Pimki.
I am not sure that this will help with the missing data though

My storage directory contains both commands and snapshot files.

This isn't the problem. The problem is in one of the template filles
(.rhtml) trying to access a wrong object.

Hi Assaph,

I am trying to get the homepage of one of my two wikis:

http://localhost:2500/wikiweblogpim/show/HomePage

I didn't mention in my previous mail that I am migrating from version 1.2.

The root page for the wiki shows ok, as does the other wiki.

I have tried accessing other page of the wiki (shows in the browser
history) but they all give the same error in that wiki.

Thanks in advance.

I changed SNAPSHOT_INTERVAL to one hour, copied the data and all of that,
and it seems to work fine.

BTW, when I only had command logs, it seemed to lose revisions (in the
sense that should be more revisions available, but the available ones seem to
be right).

Thank you, Assaph,

I've been fiddling with MadeleineService in Instiki - it is somewhat
smarter now.
See http://dev.instiki.org/changeset/7 and
http://dev.instiki.org/changeset/22

Madeleine people: please tell me if I'm doing something wrong in those
changesets, especially the first one.
If not, maybe you should use that code as an example of what a real-life
thread for snapshot taking should look like?

There still one potentially big story missing - namely, a signal handler
for graceful shutdown. I expect there must be moments during
snapshot-taking when that thread is in critical state (in the sense that
killing it would result in snapshot corruption). But I haven't looked at
that aspect seriously yet.

BTW, when I only had command logs, it seemed to lose revisions (in the
sense that should be more revisions available, but the available ones seem to
be right).

Thank you, Assaph,

There was a trivial bug in Instiki that does it, especially on a page
that is edited many times by the same person. See
http://dev.instiki.org/changeset/19

I guess that's me!

The changesets look fine. We should probably add a method to Madeleine
to allow querying about status things like that, so you aren't forced to
check for files.

I think Instiki's snapshot management is the most complete we've seen so
far, we may even merge it into Madeleine itself.

There still one potentially big story missing - namely, a signal handler
for graceful shutdown. I expect there must be moments during
snapshot-taking when that thread is in critical state (in the sense that
killing it would result in snapshot corruption). But I haven't looked at
that aspect seriously yet.

Madeleine writes snapshots into a ".snapshot.tmp"-file, forces a disk
write and only after that renames it to ".snapshot". So killing it
during the write won't break anything.
