icon4.gif   text display of ascii files not a good idea, posted by Heiko Scheit on Mon Aug 23 13:43:58 2004 
I think the text display of ASCII files, which is new in version
2.5.4, is not a good idea.  E.g. I had a large ps file attached
to one entry and it took a long time display this entry (over DSL).
Then I saw that the ps-file is displayed as text, which is not really 
useful.  

Probably it is fine to display only files ending in '.txt' per default.
In addition a file that has more than say 1000 lines should probably 
also not be displayed (as default, optional OK).  

Cheers, Heiko

elogd does not exit if there is an 'unprocessed' HUP.  So when you do 

kill -HUP <pid>
kill <pid> 

elogd will only exit after it was accessed.

Even though I can't test this right now, I assume you have to wait a little
so that elogd jumps out of the 'select()' statement between the kill
commands.  Try: 

kill -HUP <pid>; sleep 2; kill <pid>

(I think the 'select()' timeout was 1 second.?)

I think there should be size limit.  Imagine a multi MB text file (whatever it is;
elogd.c is already more than 1/2 MB and is likely to increase due to your
excellent support).  A client on an ISDN line would have to wait
several minutes and during this time elogd is busy and no other client can connect
(correct?).  Of course, if somebody really wants to see this file then there is
nothing to be done, but likely someone is flipping throught the messages using
to arrows on top to find the right entry....
So a configurable size limit seems appropriate, from which on 
only 'Display attachment' is displayed.  And/Or, for files
exceeding this limit, the first N (new config option) lines could be displayed.

But this should only influence ASCII files.  E.g. the behaviour for jpeg files
should not change, which is controlled by 'Hide default'.  Maybe a 'Display/Hide
defaut extension' option, where the extensions are listed that are to be displayed
is another idea, in addition to a 'Max Display ASCII inline size' option,
which can be set to zero to disable it altogether.

In any case, whatever you think is best.

It seems that the quick filter searches are now (2.5.4-6) case sensitive.
Could you add an option to specify this in the config file?  Or does it
exist already?
icon5.gif   compiling elog on AMD64, posted by Heiko Scheit on Wed Nov 17 18:52:40 2004 
When compiling elogd on AMD64 (in 64 bit mode) there are many 
warnings like these:

src/regex.c:3769: warning: cast from pointer to integer of different size
src/regex.c:3769: warning: cast from pointer to integer of different size
src/regex.c:3775: warning: cast to pointer from integer of different size

The reason is the (int) cast, which (I think) is not necessary.

  elogd.c shows the same warnings.

  This works OK.
 
icon5.gif   implement 'hide attribute' and 'sort attribute', posted by Heiko Scheit on Thu Dec 2 14:39:50 2004 
Could you implement a 'hide attribute' and 'sort attribute' config option?
While sort is probably not so easy to do the hide option would already 
be very useful.  What I want to do is to use elog to collect bibtex entries
which are then used to generate a bibtex file.  So, e.g. if the entry 
type 'Article' is selected I would like that all fields that do not make
sense are hidden.  Currently I just lock them.  The config looks like
this:

Attributes                  = Login, Bibtex Key, Entry Type, Address,
Annote, Author, Booktitle, Chapter, Crossref, Edition, Editor, Howpublished,
Institution, Journal, Key, Month, Note, Number, Organization, Pages,
Publisher, School, Series, Title, Type, Volume, Year, URL, Short Comment
Options Entry Type          = Article{1}, Book{2}, Booklet{3}, InBook{4},
InCollection{5}, InProceedings{6}, Manual{7}, MastersThesis{8}, Misc{9},
PhDThesis{a}, Proceedings{b}, TechReport{c}, Unpublished{d}
Required Attributes         = Entry Type
; ARTICLE
{1} Comment Author          = [required]
{1} Comment Journal         = [required]
{1} Comment Title           = [required]
{1} Comment Year            = [required]
{1} Locked Attributes       = Address, Annote, Booktitle, Chapter, Crossref,
Edition, Editor, Howpublished, Institution, Key, Organization, Publisher,
School, Series, Type


Instead of Locking the attributes, hiding them altogether would make the
entry form look much nicer.  
A further improvement would be to sort the attributes, e.g. for author I
would sort the like this, i.e. the more important entries first:

{1} Sort Attributes    = Author, Title, Journal, Volume, Pages, Year, Month,
Number, Note

Attributes not mentioned in the sort line could then be displayed 
in any order.
