 ( - todo, x - done)

 x change subst_run/str to return error (different from not found)
 x change subst_user as on serdev
 x tm : fake_env: fake also bind_address (else the default will be used

  in the failure route)

 - [core] parse_uri support for new uri params

 x [core] on sig_child, kill the processes if they don't exit in a 

   reasonable time

 - [doc] document force_rport()

 - [fifo] fix fgets error handling (it does not set errno always,
    , right now kills all ser if interrupted by a signal on ?solaris?)

 - [mem] make shm_realloc be fragmentation friendly: call shm_compact_frags
    for the small frags?, don't produce smaller frags -- be wastefull?

 - [mem] qm_compact_frags (compacts frags if possible), keep a 
         fragment count/bucket and if too much mem. is blocked in one bucket
         de-frag.

 x [mem] investigate: don't produce frag if frag size < request

       (should reduce the unrequested fragments number)

 x [mem] investigate: keep an used/unused flag per fragment, on free

       check if neighboring frags were not used and if so defragment

 - [timer] multiple timers? at least ticks should no be affected by the amount
    of work done in the timer handlers

 - [tcp] ser intiated tcp connections use INADDR_ANY (they should be bound first
   to some ip/port ?function of the dest?)

 - [tcp] need to confirm fd receipt after send_fd, before closing it (this might

  happen in tcp_send new conn.) (see FreeBSD send BUGS for more info)

 x [tcp] make send_all, send  non-blocking ready ?
 x [tcp] tcp_send w/ timeout (to avoid waiting forever to send DOS)

 - forward port fixes from testing

 - [udp] use recvmsg to get the dst ip address in udp_rcv_loop

  (it won't work on solaris, but...)

 x nathelper: extract_body broken-> uses content_length value form the 

  message instead of recalculating it + duplicate code for get_body()

 - fix check_sel_op -- add proto for uri proto checks

 - [tcp] add setting for infinite tcp conn life?

 - fix 2 different fixups for diff. no of parameter

  (add no of params to struct action?) -- linked to var. no. of params
 x alias support fot tcp/tls port numbers

 - warning builder set_advertised address support

 - grep parse_uri & replace with parse_sip_msg_uri (e.g do_action!)

 x update AUTHORS, debian/copyright, ser.8, ser.cfg.5 from stable
 x update Makefile*  from stable
 x update all package specs from stable

 - [tcp] add BUG checks for  fd > 0 && fd <= maxfd to all selects?

 - [tcp] switch to poll if HAVE_POLL defined (it's unifix so  everybody 
    should have it, but it would be slower on systems emulating it, like
    older linuxes)
 - [tcp] switch to epoll if HAVE_EPOLL defined (linux 2.6.*)

 - [tcp] switch to SIGIO if no epoll (linux only, better than poll)

 x tcp_main_loop: BUG cases should "conitnue;"

 x change len_gt into and expr (e.g msg:len).

 x sipit: uri == myself doesn't match tls port = 5061 
   -- updated: new socket_info list code should fix it
 x sipit: fix check_self & *_alias to work with tcp & tls
   -- updated: new socket_info list code should fix it

 x sipit: fix ipv6 references in check_self

 x regex subst on uris?

 x port receive.c pre_script_cb fix from stable

 x extend alias to include port numbers :

     something like alias= foo1.bar:5080 foo2.bar foo3.bar:*

 x extend listen and alias to include port numbers and protocol:

        tcp foo.bar:5063, udp foo.bar:5062, foo2.bar

 x added set_advertised_{address,port} -- was: add force_via, force_srcip a.s.o
 (the advertised addresses should be overwritable from the script).

 x ? add force_outbound_socket(ip)? (choose an apropriate socket from the

  listen list for sending the msg; works on udp only)

 release:

 - unlink_timer_lists -- unsafe ???

 x print_cseq_num max. size fix.

 x backport: tcp conn id fix to stable + destroy_tcp 
 x backport: acc mem. leak fixes
 x backport: dns mem. leak fixes (resolve.[ch])
 x backport: id_builder receive_msg mem. leak (msg_translator.c)
 x backport: check_self ipv6/case fixes (forward.c)
 x change tcp timeouts to 2 or 3 min?

 x check via ipv6 fixes and backport to stable

 x fix kill(0, SIGTERM) on startup error (will kill also the launching shell

  if non-interactive)
 - fix modules destroy (some modules will try to free uninitialized resources
    if modules_init was not called first)

 x fix CC_VER bug in newer Makefile (move DEFS after CC?)

 x openbsd 3.2 packages -> doc in share/doc (and not in doc)

 - openbsd 3.2 -> add jabber and mysql to the package

 x fix modules makefiles (so that cd modules/foo; make will also link the proper

    libs)

 x fix -march=..., or compile w/ i386 for the release

 x resolver should resolve [ipv6]

 x remove parse_uri debugging info

 - fix DBG("<%.*s>", len, _null_)

 x add -t, -w, -u -g equivalents to the config file

 x force add rport : force_rport()
 - kill all the fprintf
 see also tcp & tm
 
 
 
 not so critical:

 x replace  remaining mallocs/frees at least in msg_translator.c

 - add $(INCLUDES) to the Makefiles

 x make ser suncc ready

 - fix parse_cseq!!! (it doesnt parse 1234\n INVITE a.s.o)

 x fix 0 parameter module f. call
 x better Via parsing (handle ' ' in uri, eg: foo.bar : 1234 ; received=) and

  ipv6 addresses ([fec0:aa::01]).

 - fix format string vulnerability in log()

 - fix alignment access problems (warning on Sun)

 x (different way) add request header bitmap field for the modules

 - introduce variables & function in the script language (cfg. file)

 - ? variable number of params functions in script (no longer limited to 2)?

 - kill bind_idx

 x fix bind_address for tcp (in some  way)

 x add conflict in debs/rpms/etc (conflict w/ older ser-mysql, ser-jabber)
 x new packages ser-radius etc

 x tcp_destroy (called on ser exit)

 - BUG:?? ipv6 only and try to send to ipv4 => getsendsocket=>0 (send_ipv6=0)
   the reverse is also true

 - SUBST lumps for replies (involves setting the send_socket in forward_reply, 
   before build_res_from_res, & adding it to buid_res_from_res).

 
 High priority:

 x- parse_uri should not copy anymore the uri members (and it should not 0

  terminate them anylonger).

 x fix/replace T_REF/T_UNREF
 x review all the tm locking

 x if () {} else {}

 x plugin interface

 x ipv6 support

 x reply ("response line")
 x drop ACKs for our replies
 x add To-tag (for the replies)
 x add User-Agent (for the replies)

 
 Low priority:

 - icmp error handling

 x fix via address someday

 - fix listen=0.0.0.0 case (see [udp] use recvmsg...)

 x forward to received= if present

 - make it easier to register a statically linkable module.

 x add support for -u user and -g group (not only -u uid, -g uid)

 x change uid/gid after opening the sockets

 - exec improvments (add format strings to it)

 x command line switch for checking the config file syntax

 - config file version (a la sendmail)

 0 loop detection

 - cfg. file reload
 - flags for using names or ip adresses in Via ?

 - escape char injection/printing fix (verify all log/printed messages
  for terminal escapes and remove them)

 x handle SIGCHLD, SIGHUP

 - use a  standard lex compatible .lex format (instead of flex)

 x try & use native compiler & ld if possible

 x make install

 x init.d scripts (and rc.local? for *BSD or Slackware)

 x man page

 - autoconf scripts

 x Debian package build files
 x the same for rpm

 x the same for *BSD

 x jku: branch hash computation over canonical values
 0 jku: loop checking

 - jku: try CRC as opposed to MD5

 x freopen stdin, stdout, stderr to /dev/null

 - add a section on building ser & configuring it for maximum performance
  (-DF_MALLOC, -DNO_DBG, ... sip_warning=0, a.s.o)

 x add src_port, dst_port, proto to cfg.{y,lex}

 x generic locking lib

 x convert tm to use new locking lib

 optimizations:
 - better timer interface with hashes (a la openbsd)

 - change lumps (flags for malloc type, recursive? see COND lumps )

 - atomic ops?
 - assembly for some very common used function
 - getsock* cache
 - fd cache for tcp_send

 - dns cache? (see DNS)

 - make option to use openssl MD5 (HMAC_Init(hmac_ctx, (void*)key, 16, md5_md))
  [ 0.9.7 version is really fast ]

 
 
 tcp stuff:

 x timeout on long sends

 x tcp disable nagle 

 x set TOS to minimize delay

 x tcp locking/atomic ops review

 - tcp fix simultaneous connects (ser process is blocked until connect timeouts
  => possible DOS)

 tm optimizations:
 

 - inline/macro/drop for: get_tm_table, set_kr, lock_hash, unlock_hash,
   set_t, get_t

 - replace snprintfs int build_uac_request, *_dlg
 - fix the huge param no. in this functions (use structs if neccessary):
   build_uac_request, build_uac_request_dlg, t_uac, t_uac_dlg

 - uri2proxy - t_uac_dlg => extra malloc/free (no �roxy needed here)

 dns stuff:
  - dns cache
  - support for NAPTR (naptr(domain, pref_proto)=> srv_rec + proto => srv(srv_rec, proto) => A or AAAA => A/AAAA(name))
  - support for fallback (inside the same A/AAAA record, other ip; if fails => other SRV ; if it fails too other NAPTR
