icon5.gif   How to access PSI Elog data from other web clients , posted by Lin Wang on Wed Oct 13 02:38:34 2021 

We want to develop separate mobile web pages for the web applications deployed at CSNS accelerator, including the PSI Elog.

In Elog, is there RESTful API or HTTP/JSON or HTTP/XML interface for other web clients to access?

Or is there any workaround?

icon5.gif   Too many open files - issue?, posted by Rob Calkins on Fri Oct 15 23:57:38 2021 

Has anyone had issues with having too many files open? I'll setup my server and let it go but after a while, I end up with a lot of "cannot create socket: Too many open files" errors being reported.  I have a sync to another e-log going which I suspect is part of the cause since that e-log server hasn't had this issue. I suspect that there are files being opened, going into some return loop code and then never getting closed. I'm not a C programmer but I see lines like :

fh = open(tmp_filename, O_RDONLY);
      if (fh > 0) {
         read(fh, result, size - 1);
         close(fh);
      }

      /* remove temporary file */
      remove(tmp_filename);

This looks like it opens the file but unless the remove function closes the file, it will remain open even through the file has been deleted. Maybe this isn't the correct behaviour of 'remove' and I am mistaken?

There are also parts like :

 fh = open(textfile, O_RDONLY | O_BINARY);
      if (fh < 0) {
         printf("Message file \"%s\" does not exist.\n", textfile);
         return 1;
      }

      size = (INT) lseek(fh, 0, SEEK_END);
      lseek(fh, 0, SEEK_SET);

      if (size > (INT) (sizeof(text) - 1)) {
         printf("Message file \"%s\" is too long (%zd bytes max).\n", textfile, sizeof(text));
         return 1;
      }

This looks like for the second error, it will complain that the file is too long, return an error message but not close the file and would leave it open. Is this a reasonable avenue to pursue or am I mis-reading the code?   Thanks.

icon5.gif   wrong server HTTP status code when login failed, posted by Chris Körner on Thu Oct 21 15:17:52 2021 

Hi,

I am trying to access elog through a python client (https://github.com/paulscherrerinstitute/py_elog) and found a strage strange behavior which may be related server side problem. The python script generates get/post messages via the python requests library. This works fine so far and I can view and post messages. However, if a wrong user/password is provided, the server still returns HTTP status code "200 OK", although login failed. Instead, it should return something like "401 Unauthorized". This behavior later causes problems since the python client thinks login was successful. After experimenting around I think this could be caused by a server side misconfiguration. Any ideas?

I am not sure if this imformation is important: We use LDAP as user/password provider for elog.

Hi again!
I have one question concerning the logbook configuration. Normally, clicking on "List" takes me to the first page of the list view. Is it possible to configure the logbook so that "List" takes me to the last page instead?
