Apologies if these are known bugs, I'm very busy at the moment but I wanted to post this before I forget:

I'm using Safari on a Mac to make Elog entries.

1) The preview of some pdf attachments in edit mode displays huge areas of white space around each page. I can send examples if you'd like - please email me directly, for some reason I never get email notifications from this forum (and they aren't being tagged as spam, so I don't know where they go).

2) When that happens, the text entry area for ELcode format expands horizontally to match the huge pdf file width. Text without line feeds then doesn't wrap until the huge window width is filled, so I have to scroll horizontally all the time while editing to see what I've written.

3) So I turned off attachment previewing as a workaround (Preview attachments = 0 ). That worked fine by not expanding the entry area, but I noticed some odd behavior. The list of attachments below the text entry area is badly formatted. Here's a screen shot:

I tried to reproduce this with a new entry but the text was formatted properly for that entry.

P.S. While editing this entry, I see that the text area width is again being set by the width of the picture I've attached - try it yourself; if you try to resize your browser window smaller while editing, the text will only wrap until the width of the attachment is reached - the text no longer wraps at smaller widths than the attachment.

Your problem 1) is probably caused by ImageMagick. I use that package to convert PDFs to images. If this package estimates the paper size from the PDF incorrectly, you're screwed. You can go and actually locate the thumbnail pictures in the ELOG directory (should be named xxxxxx_yyyyyy_<name>-0.png). If you check these pictures, they are probably already huge.

Problem 3) indeed is a small bug in elogd, which I fixed in revision #2178. If you can download the SVN version and recompile elogd, you should be fine:

Thanks for the bug fix, we'll get our installation updated ASAP. And I will look into why some of my pdf file image sizes are interpreted incorrectly by ImageMagick, it might having something to do with how I've generated them.

Is it possible to set the default image size to always scale to fit the browser window? For example, this entry has a png attachment, but it still suffers from the fact that the text window size is set by the width of the png image.

If I'm forgetting something, sorry, I'm writing in a hurry!

Create a list of elog cookies, and store only these as parameters. Examplef:

int process_http_request(const char *request, int i_conn)

{

const char *cookie_list[] = { "upwd", "unm", "elmode", "urem", "wpwd", "apwd", "uname", NULL };
...
...
...
         /* store cookie as parameter */
         for(i=0; cookie_list[i]; i++) {
            if(strcmp(cookie_list[i], str) == 0) {
               setparam(str, cookie);
               break;
            }
         }

...

I'm not sure if this works, since your test

i < (int) sizeof(cookie)

still will stop parsing cookies if there is one which is too long. So I added your test plus changed the parsing to:

for (i = 0; *p && *p != ';' && *p != '\r' && *p != '\n' ; )

if (i < (int) sizeof(cookie)-1)

cookie[i++] = *p++;

cookie[i] = 0;

The modification is in the curren SVN revision (# 2162). So have a look and check that it works.

Tried 2178 and I seem to hit some endless loop when I have big cookies. The loop seems to be in this for-loop (from gdb).

I perhaps you should have:

for (i = 0; *p && *p != ';' && *p != '\r' && *p != '\n' ; )

if (i < (int) sizeof(cookie)-1)

cookie[i++] = *p++;

else
break;

cookie[i] = 0;

... Seems to be working for me =)

Yepp, you're right. I applied your change to the distribution code.

Hello,

Please could you help me.

We have 2 elog servers synchronized every minute via Elog mirroring function.

2 or 3 times a week, the slave crashes and we have to restart Elogd. I have found in /var/log/messages the same message every time elogd crash :

xmalloc: not enough memory

Thanks.

Dominique Bolla.

Attachment not downloaded when elog is mirrored ?

Hello,

I just mirrored a logbook and noticed attachments are missed.

On another similar note, when an email notification is sent and the post has attachment, the attachment show up in the email BUT there is nothing in them.

Anything special I should know about those attachments ?

Thank you,

F.Sabatié

Missing icons when running trough Apache proxy, elogd version 2.75

Tested this using the 2.6.1 version which comes packed with ubuntu-dapper and a 2.7.5 version I've compiled from source.

If I compile the 2.7.5 version from source and start it using

sudo /usr/local/sbin/elogd -c /usr/local/elog/elogd.cfg

config snippets below

---------------------------------

/usr/local/elog/elogd.cfg:

[global]
port = 8080
;url = http://solsikker.dmi.dk/elog/

[demo]
Theme = default
Comment = General linux tips & tricks

Options Category = General, Hardware, Software, Network, Other
Extendable Options = Category
Required Attributes = Author, Type
Page Title = ELOG - $subject
Reverse sort = 1
Quick filter = Date, Type
------------------------------------

The icons show up !!

If I go through an apache proxy (config snippets below)

----------------------------------------

/usr/local/elog/elogd.cfg:

ProxyPassReverse /elog/ http://solsikker.dmi.dk:8080/
<Proxy *>
Order deny,allow
allow from all
</Proxy>

Actually your combination of "bottom text" with "protect selection page" caused the trouble. If fixed the bug in revision 2189.
