Very good idea! I changed that in ELOG V2.7.5-2139. The fix will be contained in the next release.

elog -v -h my.apache-proxy.server -d elog -l Accelerator -p 443 -s -u johndoe xxxxx -a Category=LN -a Subject=Test -a Author=IDoNotExist -n 1 -m entry.txt 
(johndoe is an existing user)

 

The entry is created with "IDoNotExist" as the Author name, instead of the correct name for the user johndoe,
and the Author Email attribute is blank.

Is there a way to enforce preset and locked attributes in the elogd server? (As a client could connect
with any arbitrary software, not just elog.)

Indeed "preset" and "locked" attributes are not obeyed if entries are submitted via the elog tool. The is because if you use a browser, the input form is created by elogd. If you use a locked attribute, the input filed for that attribute is not shown for example. If you use the elog tool, it directly submits an entry not knowing anything about the input form. To make this work, elog would first have to request the input form, then interprete all the HTML, figure out if an attribute is locked or not, then display an error if you try to submit that attribute. Since parsing of HTML is not implemented in elog, this is currently not possible. 

Originally I thought that this is not such a problem. Mostly elog is used to produce some automatic entries, where the authorship is of minor interest. But I guess you are afraid that one use could submit an entry under another user's name, right? Well, I hoped that in scientific collaborations nobody is that evil ;-)

Well, I will try to do something here in order to fix this. Will come back to you.

Actually I found a way around. The "Subst xxx" is evaluated after you submit an entry, so it also works for the elog tool. So all you need in your config file is:

Subst Author = $long_name

and it will do the job.

 This problem has been fixed in revision 2.7.5-2143. Please upgrade.

Hi,

elogd sometimes crashes when there are large cookies. Or I'd guess it has something to do with the cookies, elogd crashed over and over again until I cleaned out cookies and authenticated sessions in firefox, then it stopped.

When I run "elogd -v" in gdb, and someone does:

 Stefan,

perhaps there should be something like the bold text below in elogd.c:

int process_http_request(const char *request, int i_conn)^M
...

   /* extract cookies */^M
   if ((p = strstr(request, "Cookie:")) != NULL) {^M
      p += 6;^M
      do {^M
         p++;^M
         while (*p && *p == ' ')^M
            p++;^M
         strlcpy(str, p, sizeof(str));^M
         for (i = 0; i < (int) strlen(str); i++)^M
            if (str[i] == '=' || str[i] == ';')^M
               break;^M
         if (str[i] == '=') {^M
            str[i] = 0;^M
            p += i + 1;^M
            for (i = 0; *p && *p != ';' && *p != '\r' && *p != '\n' && i < (int) sizeof(cookie); i++)
                      cookie[i] = *p++;

...

[demo]
Attributes = Author, Type, Subject, Old/New
Options Old/New = Old, New
Quick filter = Type, Old/New

 Thanks for the advice!

I've just had time to set up a test for this using both empty and populated logbooks (which don't have Hardware/Software in every entry as the field was added recently) and newly created logbooks (which have consistent attributes) and saw the problem on . 

The control ("Hardware/Software") causing the problem has three options "Hardware Only", "Software Only" and "Both".  The problem happens every time you click on the "-- Hardware/Software --" (i.e. All) option in the Quick Filter after having previously selected one (or more) of the options as a filter.  This produces the error:

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
*   This problem can sometimes be caused by disabling or refusing to accept cookies.

I ran elog with a trace (attached) which shows lots of:

select(1024, [5], NULL, NULL, {1, 0})   = 1 (in [5], left {1, 0})
recv(5, "GET /Change_Log/?Hardware%2FSoftware=_all_ HTTP/1.1\r\nHost: localhost:8080\r\nUser-"..., 100000, 0) = 619
stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=1323, ...}) = 0
time(NULL)                              = 1227528904
send(5, "HTTP/1.1 302 Found\r\nServer: ELOG HTTP 2.7.5-2130\r\nConnection: Keep-Alive\r\nKeep-A"..., 199, 0) = 199
send(5, "<html>redir</html>\r\n", 20, 0) = 20

messages after selecting "-- Hardware/Software --"

The only difference between today's test and last week's is that today the browser is on the local machine.

I also attach my (anonymised) elogd.cfg

Hope this helps

regards

Steve

Thanks to your detailed description I could reproduce and fix the problem. Please download SVN revision #2144 and give it a try.
