Converting from elog 2.9.something to new elog 3.1.0 elogd refuses to start, instructs running elconv in one logbook.

When I do so, elconv converts a existing mhttpd-style elog entries to the new format (the corresponding new-format entries already exist)
and deletes everything else - this is very bad.

So there are 2 bugs:
- elogd should not tell us to run elconv when both old-style and corresponding new-style elog entries exist
- elconv should not delete all existing new-style elog entries.

I confirm that elconv *does* delete all new-style elog entries - with strace, I see it issue "unlink" on every elog entry.

What a disaster!

this elog gives errors sending mail through PSI email server. (did not capture the error messages, sorry). K.O.

this elog offers me to edit a draft message, then yells at me "only some other user can edit this draft!!!".
methinks I should only be offered to edit draft messages that I own or I can edit. K.O.

elogd 3.1.0 moves all elog entries into year-named subdirectories. this feature makes it incompatible with older elogs and so should be clearly mentioned in the documentation,
in the release announcement and in the release and migration notes. K.O.

I am one of those users. The elog for the ALPHA experiment at CERN goes back to 2006 or so,
with large volume of messages and huge number of attachments. The MIDAS forum elog goes back to 2003.
The TRIUMF DAQ internal elog goes back to 2001.

I think the new organization is an improvement.

No, go. The MidasWikiUserName cookie will log me out of the MidasWiki, etc.

But why are MidasWiki cookies sent to the elog? Ah, yes, they all run from the same https://midas.triumf.ca.

This explains why elog complains about unexpected cookies - elogd does not expect to receive
mediawiki cookies - it does not expect to share the https:// connection with somebody else.

This is good to know for the future. (I.e. if mediawiki is confused by elogd cookies).

The text should read:

the first time you run the new elogd against old elog data,
all existing entries will be moved into by-year subdirectories
and the old elogd will not work anymore.

Older versions of elogd have a problem with sending long attachements - the send() syscall is not protected against interrupt by SIGALARM. This seems to be fixed in non-SSL builds of current elog (version 3+), 
but for SSL builds, the error handling for the SSL_write() function looks incorrect. In addition, from OpenSSL documentation it is not clear if SSL_write() can handle signal interrupts at all.
