*******************************************************************************
**
** This file contains code used to implement the Fossil chatroom.
**
** Initial design goals:
**
**    *   Keep it simple.  This chatroom is not intended as a competitor
**        or replacement for IRC, Discord, Telegram, Slack, etc.  The goal
**        is zero- or near-zero-configuration, not an abundance of features.
**
**    *   Intended as a place for insiders to have ephemeral conversations
**        about a project.  This is not a public gather place.  Think
**        "boardroom", not "corner pub".
**
**    *   One chatroom per repository.
**
**    *   Chat content lives in a single repository.  It is never synced.
**        Content expires and is deleted after a set interval (a week or so).
**
** Notification is accomplished using the "hanging GET" or "long poll" design
** in which a GET request is issued but the server does not send a reply until
** new content arrives.  Newer Web Sockets and Server Sent Event protocols are
** more elegant, but are not compatible with CGI, and would thus complicate
** configuration.

** WEBPAGE: chat-poll
**
** The chat page generated by /chat using a XHR to this page in order
** to ask for new chat content.  The "name" argument should begin with
** an integer which is the largest "msgid" that the chat page currently
** holds.  If newer content is available, this routine returns that
** content straight away.  If no new content is available, this webpage
** blocks until the new content becomes available.  In this way, the
** system implements "hanging-GET" or "long-poll" style event notification.
**
**      /chat-poll/N
**
** If N is negative, then the return value is the N most recent messages.
** Hence a request like /chat-poll/-100 can be used to initialize a new
** chat session to just the most recent messages.
**
** Some webservers (althttpd) do not allow a term of the URL path to
** begin with "-".  Then /chat-poll/-100 cannot be used.  Instead you
** have to say "/chat-poll?name=-100".
**
** The reply from this webpage is JSON that describes the new content.
** Format of the json:
**
** |    {
** |      "msg":[
** |        {
** |           "msgid": integer // message id
** |           "mtime": text    // When sent:  YYYY-MM-DD HH:MM:SS UTC
** |           "xfrom": text    // Login name of sender
** |           "uclr":  text    // Color string associated with the user
** |           "xmsg":  text    // HTML text of the message
** |           "fsize": integer // file attachment size in bytes
** |           "fname": text    // Name of file attachment
** |           "fmime": text    // MIME-type of file attachment
** |           "mdel":  integer // message id of prior message to delete
** |        }
** |      ]
** |    }
**
** The "fname" and "fmime" fields are only present if "fsize" is greater
** than zero.  The "xmsg" field may be an empty string if "fsize" is zero.
**
** The "msgid" values will be in increasing order.
**
** The "mdel" will only exist if "xmsg" is an empty string and "fsize" is zero.
