Currently this is defined as a maximum of 100 literals in the cfg file. I would like to see the option to reference an external text file as input for this. 

I will put this on the wish list.

As a side question, I would also like to increase the max to a greater value, for example, even 5000. I assume I can change the source (I recall var was something like "List_Option_Max") and see if that would still work, but would you know offhand if that would cause a problem anywhere else?

 

I limited this to 100 entries because it will be hard to handle it. Imagine a drop-down list box with 5000 entries. It would fill your complete screen and you still won't see all 5000 entries. In that case it might be better to use a free text field and enter the attribute value as free text.

You can increase MAX_N_LIST in elogd.c, but at some point you will get a stack overflow and elogd will just crash.

Ok, that makes sense, so I changed it to

Sort Attribute Options Status = 1

as you suggested.

excuse my butting in ...  I've found the exports useful in the past - however, is is possible to run the export from a script in order to produce reports?  Utilities like wget won't work as the export process doesn't return the data as html.

That's not true. wget does work. Try that one:

wget --no-check-certificate -O export.csv https://midas.psi.ch/elogs/linux+demo/?mode=CSV1

actaully wget doesn't care if the return is HTML or a GIF image or anything else, it just saves it into the output file.

Hello

Just a few fckeditor related questions. How do elog versions and fckeditor versions relate. ?

Can I just drop another version of the fckeditor over an other version?  What things should I consider when doing so ?

thanks for you're time.

The relation is not very "stong". In the past I updated between major version of fckeditor without chaning any elog code, so just give it a try.

Dear Sirs,

searching for keywords regular expression becomes very long. Are there any other type easy multiple keyword search supported. For example a keyword search like keyword1 & keyword2 results in different output than a keyword search like keyword2 & keyword1. A simple keyword search like "keyword1 & keyword2 and keyword2 &keyword1 should find all documents in a database containing both keywords resulting in the same output. 

I had this request already several times. Indeed I myself am not very happy with regular expressions. If anybody knows of any other convenient search method, together with freely available C code, I'm more than happy to include this into elog.

To be honest I'm not an expert on SSL. I just use following code inside ELOG to initialize the SSL connection:

SSL_CTX *init_ssl(void)
{
   char str[256];
   SSL_METHOD *meth;
   SSL_CTX *ctx;

   SSL_library_init();
   SSL_load_error_strings();

   meth = SSLv23_method();
   ctx = SSL_CTX_new(meth);

   strlcpy(str, resource_dir, sizeof(str));
   strlcat(str, "ssl/server.crt", sizeof(str));
   if (!file_exist(str)) {
      eprintf("Cerificate file \"%s\" not found, aborting\n", str);
      return NULL;
   }
   if (SSL_CTX_use_certificate_file(ctx, str, SSL_FILETYPE_PEM) < 0)
      return NULL;

   strlcpy(str, resource_dir, sizeof(str));
   strlcat(str, "ssl/server.key", sizeof(str));
   if (!file_exist(str)) {
      eprintf("Key file \"%s\" not found, aborting\n", str);
      return NULL;
   }
   if (SSL_CTX_use_PrivateKey_file(ctx, str, SSL_FILETYPE_PEM) < 0)
      return NULL;
   if (SSL_CTX_check_private_key(ctx) < 0)
      return NULL;

   strlcpy(str, resource_dir, sizeof(str));
   strlcat(str, "ssl/chain.crt", sizeof(str));
   if (file_exist(str))
      SSL_CTX_use_certificate_chain_file(ctx, str);

   return ctx;
}

Maybe I need something different for chain certificates, but I don't know. I just copied these calls from the 
example which comes with the libssl library which I'm using. Maybe somebody has an idea how this could be 
improved. Actually looking at the code I see that the 'chain.crt' file is used. If you send me your files 
privately I could try them and see if I get a specific error code from the SSL library.

Allen wrote:

When we set Fix text = 1, according to the syntax, this should prevent users from modifying the text field during an edit, but it looks like it is blocking access at both time of edit and creation, meaning you can never add anything to it.  Is that the intended functionality?

Thanks for reporting that bug. I realized that this was not working at all since a long time. I fixed it in SVN revision 2245.

Maybe there is a simple way.
If I understand it correctly, the entries are accepted/rejected for inclusion in the search result list based on one call to regexec. In order to search for N keywords, you could replace this by a loop of N calls to regexec, and only accept the entry if all of them find a match.


That's right, but some people want something like

(NOT "House" and "Car") OR "Tree"

Using regex'es is a bit exotic for most users. So I hope there is some source code which implements a Google type search more or less 1:1. And Google does not use regex'es (is that right?). Here is the syntax for the Google search:
