Another, possibly better, option occurred to me. If the webserver supports
it, configure it to "pass through" to Fossil and run Fossil in server mode.
Essentially, the webserver would be acting as a proxy server for the base
URL for Fossil. ( I recall seeing something about how to configure Fossil
to operate from behind a proxy)

Well, I was actually wrong. fcgiwrap actually *can* wrap bash cgi scripts (and 
also, perl, etc.)
So, the problem is solved and I can recommend using fcgiwrap tool for hosting 
fossil repositories
on high performance web servers without CGI support, like nginx and rwasa.

I'm trying to come with documentation to better explain how that
works.  My *first draft* is currently up at
https://www.fossil-scm.org/fossil/doc/trunk/www/aboutcgi.wiki and let
me know if it helps any.  Remember that the document is a
work-in-progress.

But how to make web server run fossil with command line arguments? 
Some wrapper is still needed, or I am missing something?

Simply run "fossil cgi FILE" where FILE is the name of a configuration
file.  FILE should look like this:

 repository: /home/of/your/repository.fossil

Other lines are possible, but the above is sufficient to get you
started.  Probably this deserves to be better documented

So, is it possible to use fossil in CGI mode without wrapping it with bash CGI 
script?

Indeed, I found very similar tool "fcgiwrap": https://github.com/gnosek/fcgiwrap
Will try to use it to wrap fossil in CGI mode, as long as the SCGI mode of 
fossil 
is very similar wrapper, only built-in. One layer less is always good IMHO.

OpenBSD's [httpd][1] is another FastCGI-only serer.

[1]: http://man.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man8/httpd.8

They use a FastCGI to CGI wrapper server (named [slowcgi][2]) that
translates FastCGI requests to the CGI protocol.

SCGI works the same way - it opens a socket to a persistent process
and sends multiple requests over to the process.

Fossil handles this the same way it handles the "fossil server"
command.  There is one persistent process that does nothing but accept
SCGI requests.  For each request, that process forks a separate child
to service that request.

You can see this better by noting that there is no "fossil scgi"
command, but rather a "--scgi" switch on the "fossil server" command.
The same logic that deals with HTTP requests also deals with SCGI
requests - it just understands a different protocol.

Were we to add FastCGI capabilities to Fossil, no doubt there would be
yet another "--fastcgi" option on the "fossil server" command.

As i recall (but it's been 6 or 8 years), FastCGI works by starting a
single app instance and piping CGI data through it multiple times (for
multiple requests). If that's the case... Fossil relies on the app shutting
down to free memory, and would be incompatible with such a mechanism. Also,
IIRC, FastCGI provides drop-in "replacements" of the read() and write()
calls via macros, but use the wrong signature for (IIRC) the write()
routine (they use a non-const pointer for the source memory, whereas the
real API uses a const one).

Recently I implemented FastCGI framework in assembly language (after long 
wandering about SCGI and FastCGI). Yes, it is more complex, but is more 
flexible as well.

Fossil only support CGI and SCGI.  What web server are you running
that has only FastCGI support.

When I was looking into alternatives to plain old CGI, I found that
the FastCGI protocol was very complex and hard to implement, whereas
SCGI was quite simple.  So I took the simpler approach.  Are there
some advantages to FastCGI that I am unaware of?
