Hi all!
What is the current status/progress on mod_ftp? I haven't seen much on
[EMAIL PROTECTED] about it since the graduation...
In any case, we'd really like to get mod_ftp in a usable state so we
can use it on our anonftp frontends. We currently use vsftpd and are
really happy with it, but we would REALLY want to have the cache
handled by mod_cache used by FTP too. We have already convinced rsync
into using the cache by a LD_PRELOAD hack, unfortunately this doesn't
work too well with ftpd's since they rely on chroot() to work.
So, how close is mod_ftp to handle this for us? I'll list the
requirements we have and comment, and hopefully the Really Clued Ones
will chime in with additional comments/status/etc:
In order to use mod_ftp on ftp.acc.umu.se (which runs httpd 2.2.4 with
our mod_disk_cache jumbopatch) we need it to:
* Play well with mod_cache, if a file has been requested with HTTP a
FTP request should reuse the cached copy. Last time I checked
mod_ftp only did subrequests which mod_cache didn't act on. Of
course files requested with FTP and thus cached should cause a HTTP
request to use the cached copy (although with a revalidation to get
current headers I guess). I think this won't work too well with
vanilla mod_disk_cache, however our mod_disk_cache jumbo patch
caches the body in a hash based on r->filename to solve the
name-space issues.
* Only anonyomous read-only-access is required. I think this is
working today.
* Download-related items like file listings, continuation, etc MUST
work.
* Both passive and active mode MUST work. I think there was some
issues causing it to always use 0.0.0.0 in passive mode last time I
checked.
* Large file support MUST work (we serve DVD images). Last time I
checked there was a whole slew of LFS issues with the mod_ftp
globbing code which was simply broken since it didn't use the information
gathered by configure and didn't use APR - it should be ripped out
and replaced with APR stuff instead IMHO. It makes no sense to keep
that mess just o keep httpd 2.0 compatibility...
* IPv6 MUST work. I think this is being addressed.
* Probably something that I forgot so it can't be that important ;)
I (and other fellow computer club people) would be happy to hack on
small bugs and issues, but the more hairy things like the
mod_ftp/mod_cache interaction and the globbing mess really needs a
Clued Httpd Developer sorting out the various odds and ends.
