-------------------------------=| HISTORY |=-------------------------------

Bump : 1.00
Date : 20-08-2010
Dude : megacz

Stat : NO
0001 : Although idea was taken from  SWLoader, code  will be  written  from
0001 : scratch  to eliminate certain limitations. At the moment  there is a
0001 : packet skeleton  and some helper functions. Work will resume as soon
0001 : as  the device make/kill and  enhanced packet related functions will
0001 : be ready.



Bump : 1.01
Date : 27-11-2010
Dude : megacz

Stat : FA
0001 : Packet handling was established. It is possible to interrupt in-loop
0001 : handler, so that immediate termination is possible.

Stat : FA
0002 : File handling was implemented in  '___dos_addclient()'. For now only
0002 : filenames are accepted.



Bump : 1.02
Date : 28-11-2010
Dude : megacz

Stat : FA
0001 : Basic  channel handling was  implemented. Now merged  with file I/O.

Stat : BF
0002 : From  now on all files will be opened in  MODE_OLDFILE  for  maximum
0002 : security. This way appending is also possible.

Stat : BF
0003 : Window requests: CONSOLE, * are now satisified using user's process.



Bump : 1.03
Date : 29-11-2010
Dude : megacz

Stat : FA
0001 : Caller  signaling was implemented  so user can  now be notified when
0001 : FDR goes down for some reason.

Stat : BF
0002 : Client  allocation was reworked  due to design  flaw that would make
0002 : it unable to switch to clustered memory in the future.

Stat : BF
0003 : Channel and file name truncation is now being performed before going
0003 : to search. This makes sure that too long names are always matched.



Bump : 1.04
Date : 13-12-2010
Dude : megacz

Stat : FA
0001 : Dead channel removal was added using access counter. It is now up to
0001 : FDR  to cleanup the channel. This makes it possible to have some I/O
0001 : treshold so clients can init channel, leave it and come back later.

Stat : FA
0002 : Buffered and non-buffered writes are now possible using two distinct
0002 : functions.



Bump : 1.05
Date : 21-12-2010
Dude : megacz

Stat : FA
0001 : Fast  ANSI  filtration option was added upon relay attempt per file.

Stat : FA
0002 : Text to be  relayed can now contain  prefixes per line. This will be
0002 : useful  to match weird  behaviour  based on timestamps  and addesses
0002 : that can be inserted before actual program output.



Bump : 1.06
Date : 23-12-2010
Dude : megacz

Stat : FA
0001 : Default  channel can now be set so all  'CONSOLE:' requestes will be
0001 : routed to it.

Stat : BF
0002 : ANSI  stripping is now being done just once using cache. So there is
0002 : no need to repeat this per file in the chain.

Stat : BF
0003 : Client  signaling and auto. file closing are now mutually exclusive!
0003 : This is because  if you do not care about FileHandle then you cannot
0003 : receive the signal and vice versa.



Bump : 1.07
Date : 25-12-2010
Dude : megacz

Stat : FA
0001 : FileHandle address as input was implemented. Can now relay purely by
0001 : address. Random inputs are checked  against OS constant to make sure
0001 : it is really FH.

Stat : FA
0002 : Implemented  symbolic password  protection per channel using weakest
0002 : hash routine.

Stat : BF
0003 : Workaround in prefix stuffer was added so that  CRLF does not messup
0003 : the resulting line.



Bump : 1.08
Date : 26-12-2010
Dude : megacz

Stat : BF
0001 : Channel  can only be automatically  deallocated when it is not being
0001 : protected  with symbolic password. This  ensures user  intention  no
0001 : matter global settings.

Stat : BF
0002 : Channel  that is the default  and password  protected  was alterable
0002 : without providing a password!

Stat : BD
0003 : Relay  loop causes packets to hog the CPU  for too  long before they
0003 : arrive  at the corresponding  ports. Output  is not  in sync  on all
0003 : console windows... Maybe harmless, but possible trouble maker.



Bump : 1.09
Date : 07-01-2011
Dude : megacz

Stat : FA
0001 : Virtual  rollover files support was added. Now channels can memorise
0001 : the traffic using private file that can be read by the user.

Stat : FA
0002 : Channels are  now date/time stamped to have a clue how long they are
0002 : up.



Bump : 1.10
Date : 11-01-2011
Dude : megacz

Stat : BF
0001 : ANSI  is  no longer being  stripped for  virtual files. From  now on
0001 : virtual files  memorise everything  without alterations and the user
0001 : can request data without ANSI when needed.



Bump : 1.11
Date : 13-01-2011
Dude : kowalsky

Stat : BF
0001 : There was a bug in  `___dos_remdeadchans()'  that trashed  memory on
0001 : potential channel removal. Node was not buffered before `Remove()'.

Stat : BF
0002 : Potential illegal memory read in formatted text export was found and
0002 : is now fixed.

Stat : BF
0003 : Missing error codes were added to the client initialization routine.



Bump : 1.12
Date : 15-01-2011
Dude : megacz

Stat : NO
0001 : Major  code cleanup before  next phase. Lets  hope there  is no more
0001 : nasty bugs.

Stat : BF
0002 : Inconvinience detected in 1.08/0004 was fixed by switching loop into
0002 : cooperative mode. This helps when FDR runs at priority below CON.



Bump : 1.13
Date : 01-02-2011
Dude : megacz

Stat : FA
0001 : Extensive status generation was implemented so one can 'type <FDR>:'
0001 : and see what is where. The  very same formatting options can also be
0001 : used in prefix addon.

Stat : BF
0002 : Structures  were cleaned up from  old, now obsolete variables. Did i
0002 : miss something?



Bump : 1.14
Date : 02-02-2011
Dude : megacz

Stat : BF
0001 : Switched to  clustered client allocation so  that device access will
0001 : be faster and guaranteed for up to 256 clients. 

Stat : BF
0002 : ANSI in fmt is now being filtered upon expansion so that overhead is
0002 : greatly reduced when relaying.



Bump : 1.15
Date : 05-01-2011
Dude : kowalsky

Stat : BF
0001 : Each  read from virtual files must be tracked independently(!) Added
0001 : new variables to client structure that are attached upon request.

Stat : BF
0002 : Virtual  files have not been  reallocated properly on request. There 
0002 : could be situation where unallocated file was valid.



Bump : 1.16
Date : 09-02-2011
Dude : megacz

Stat : FA
0001 : Added a  bunch of new formatting  options to the  parser. Status was
0001 : expanded too.

Stat : BD
0002 : Sometimes  packets arrive in wrong order. What the hell is going on?



Bump : 1.17
Date : 12-02-2011
Dude : kowalsky

Stat : BF
0001 : Circular  reference was eliminated. You  cannot relay  over the same
0001 : device with own channels since it is single tasking(!)



Bump : 1.18
Date : 15-02-2011
Dude : kowalsky

Stat : BF
0001 : Checked  few things  and it looks  that the routine  responsible for
0001 : packet fetching is broken. This would explain  1.16/0002. I reworked
0001 : it.

Stat : BF
0002 : Virtual  file removal code lacked  direct pointer comparison so that
0002 : it would be the other file that could have been removed(!)

Stat : BF
0003 : Client slots have been reused silently  due to commented  `Remove()'
0003 : in deallocation routine(!) Enforcer  was silent  because  memory was
0003 : already allocated.



Bump : 1.19
Date : 19-02-2011
Dude : megacz

Stat : FA
0001 : Added  a channel option that allows  to terminate all files if there
0001 : are no clients. Flush is now more effective.

Stat : NO
0002 : Code cleanup before next phase:  Single tasking pipe implementation.



Bump : 1.20
Date : 20-02-2011
Dude : kowalsky

Stat : BF
0001 : ANSI  filtering switches were  recognized wrongly  in relay routine.
0001 : Fixed.



Bump : 1.21
Date : 01-03-2011
Dude : megacz

Stat : FA
0001 : After  many attempts finally introducing  first single  tasking pipe
0001 : implementation that sort of works :-) .



Bump : 1.22
Date : 02-03-2011
Dude : megacz

Stat : BF
0001 : Added  special code that kicks all pipe  callers who  wait for reply
0001 : if channel is to be removed. Otherwise they would block forever!



Bump : 1.23
Date : 03-03-2011
Dude : kowalsky

Stat : BF
0001 : Added pipe  sanity check before read/write op so that no blockage is
0001 : possible if user removed pipe facility from channel between packets.

Stat : BF
0001 : Added small flagset that allows to cause intentional IO failure when
0001 : required.



Bump : 1.24
Date : 05-03-2011
Dude : megacz

Stat : FA
0001 : Added  no-EOF option so that multiple  writers can output to channel
0001 : and the last one can generate end-of-input.

Stat : FA
0002 : Added  CON query support so  that the  very first console handler on
0002 : the  list will be used  to communicate in  RAW mode. This  allows to
0002 : send  private CSI  sequences and read  the answer.  This is not pipe
0002 : related.



Bump : 1.25
Date : 08-03-2011
Dude : megacz

Stat : FA
0001 : Implemented  ACTION_DISK_INFO that  allows to forward this packet to
0001 : first  console on the channel  so that programs will  get what  they
0001 : expect. In case  there is no console  handler default values will be
0001 : returned.



Bump : 1.26
Date : 09-03-2011
Dude : kowalsky

Stat : BF
0001 : Fixed  CSI query mode  to work aside  virtual files.  Now  both  are 
0001 : possible. User has to use  `SetMode()' to decide what source to read
0001 : from.



Bump : 1.27
Date : 12-03-2011
Dude : megacz

Stat : FA
0001 : Implemented  path-finder that user  can install on a  channel  which
0001 : will  be able to find primary  path as established  earlier by first
0001 : caller  within -this- task. The  idea is to follow  default  channel
0001 : as  it changes per task. So  each time user 'Open()'s  this  channel
0001 : it  will  find  the  default  route  automatically. This  will  work 
0001 : regardless of if channel is requestable through 'CONSOLE:'.



Bump : 1.28
Date : 13-03-2011
Dude : megacz

Stat : BF
0001 : Added router support for  relays and pipes so that both can be found
0001 : with two or more channels.

Stat : NO
0002 : Next phase is to implement ACTION_WAIT_CHAR that works with pipes in
0002 : a single process!



Bump : 1.29
Date : 17-03-2011
Dude : kowalsky

Stat : BF
0001 : Code  responsibe for CSI queries  was reworked. Consider direct mode
0001 : switches  rather than forwarding which  may not be what is needed at
0001 : the moment.



Bump : 1.30
Date : 18-03-2011
Dude : kowalsky

Stat : BF
0001 : A bug  in pipe writer code that did not care about outstanding reads
0001 : was fixed. Now all these readers will receive EOF.

Stat : BD
0002 : Flushed  channels counter does not  remember peek value. Not  really
0002 : important but this should be fixed at some point.

Stat : BD
0003 : Sometimes FDR crashes when successful ACTION_DIE  was sent. It seems
0003 : there is a bug in device kill function. Will investigate later.



Bump : 1.31
Date : 24-03-2011
Dude : kowalsky

Stat : BF
0001 : File status  line was produced with  wrong formating options. Number
0001 : of clients was displayed as a number of flushed channels(!)



Bump : 1.32
Date : 25-03-2011
Dude : megacz

Stat : FA
0001 : Added low level structure access to it is possible to alter  FDR own
0001 : settings from outside. For now ACTION_LOCK_RECORD/ACTION_FREE_RECORD
0001 : are used.



Bump : 1.33
Date : 01-04-2011
Dude : megacz

Stat : FA
0001 : Implemented wait char packet using packet synchroniser as taken from
0001 : experimental  branch. It  is possible  to use single  timer  request
0001 : which is renewed periodically at decent rate and enqueue dos packets
0001 : by sniffing on message port.

Stat : FA
0002 : Added  interrupt driven packet  forwarder so that it is  possible to
0002 : glue  client pointer to dp_Res2. The  drawback is that  clients must
0002 : now use private message ports.



Bump : 1.34
Date : 05-04-2011
Dude : kowalsky

Stat : BF
0001 : Fixed  packet prediction in packet synchroniser so all writes are to
0001 : be replied in the right order.

Stat : BD
0002 : It is not safe to forcibly unmount  FDR  now due to packet forwarder
0002 : that sits in the main code segment(!)

Stat : BD
0003 : Treshold is too unstable in `WaitForChar()' when using single FDR in
0003 : many processes. The CPU load is enormous(!)

Stat : NO
0004 : Ahhh, cramp! Did  not take that into account. The CPU load is indeed
0004 : way too high. -- megacz



Bump : 1.35
Date : 09-04-2011
Dude : megacz

Stat : BF
0001 : Fixed  a bug in pipe  handling where  read request  was possibly not
0001 : satisified in whole.

Stat : BD
0002 : Weird  deadlocks have been  observed when  there is  too many  WFC()
0002 : requests. Looks like packet synchroniser is to blame...



Bump : 1.36
Date : 01-05-2011
Dude : megacz

Stat : BF
0001 : Packet  synchroniser  was  dropped. I  do  not want  anyone  to have 
0001 : anything to do with this code. Todays episode: Sortcuts cost more.



Bump : 1.37
Date : 03-05-2011
Dude : megacz

Stat : FA
0001 : Now clients have their  own timer request spaces that they attach to
0001 : the  wait list. Special  timer packet  was added  to  poll completed
0001 : requests. Considering 1.34/0003 fixed. Considering  ACTION_WAIT_CHAR
0001 : implemented.

Stat : NO
0002 : What  a relief(!) This  code is superrior compared to friggin packet
0002 : predictor. I  see that the  `moonbuggy'  keeps up with the  timmings
0002 : while I browse with `lynx'. Well done(!) -- kowalsky



Bump : 1.38
Date : 04-05-2011
Dude : kowalsky

Stat : BD
0001 : Too soon victory was celebrated(!) I receive random crashes when two
0001 : instances of `lynx' are running in `amiscreen'.

Stat : BF
0002 : Requests must be intially sorted out when writer cannot do the op at
0002 : this time or callers that are now waiting will never resume(!)



Bump : 1.39
Date : 06-05-2011
Dude : megacz

Stat : NO
0001 : 1.38/0001: Crash here too! Spent quite  a time but still cannot find
0001 : the cause of this :-( .

Stat : BF
0002 : Timer  request skeleton is now  being created on init and copied per
0002 : caller instead of setting all from scratch on each call.



Bump : 1.40
Date : 13-05-2011
Dude : kowalsky

Stat : BF
0001 : Found the problem of 1.38/0001. In  `___dos_checkperiod()'  node was
0001 : removed  after it  could have  already  been removed by the timer or
0001 : when requests were about to be sorted out(!)



Bump : 1.41
Date : 20-05-2011
Dude : megacz

Stat : NO
0001 : Code cleanup time. Removing  all dirt permanently. Copy of  1.40 can
0001 : be found in garbages.



Bump : 1.42
Date : 29-03-2012
Dude : megacz

Stat : BF
0001 : Packet  forwarder is now a modular  segment that gets  loaded on FDR
0001 : startup. This fixes 1.34/0002.



Bump : 1.43
Date : 09-04-2012
Dude : megacz

Stat : FA
0001 : Implemented  VCR support  which allows to  track packet delays using 
0001 : high precision timer. This allows to record console interaction with
0001 : real intervals.



Bump : 1.44
Date : 10-04-2012
Dude : megacz

Stat : BF
0001 : Delays are being computed using 'GetSysTime()' instead of taking the
0001 : time from E-Clock. Overall playback feeling is better.



Bump : 1.45
Date : 11-04-2012
Dude : megacz

Stat : BF
0001 : ESC  sequence tracker was added to  VCR to detect when it is safe to
0001 : output delay sequence.

Stat : BF
0002 : Export  function  '___dos_vcrexport()' uses now temporary packets to
0002 : deal with pre and post data chunks.



Bump : 1.46
Date : 18-04-2012
Dude : megacz

Stat : BF
0001 : Delays  are now to be NULLed when channel is going to be cleaned up.
0001 : This prevents extreme delays on new VCRs.

Stat : FA
0002 : Added special VCR macros to private header to easily deal with sync.
0002 : Now delay sequence is of:  'ESC[#p'(delay in micros) which should be
0002 : ignored by most terminals since it lacks second param. Clip sync is:
0002 : 'ESC[0000p'.



Bump : 1.47
Date : 01-04-2013
Dude : megacz

Stat : FA
0001 : Added kludgy ACTION_WRITE  packet defragmenter that can be activated
0001 : by sending ACTION_INHIBIT (dp_Arg1 == 1) - On, (dp_Arg1 == 0) - Off.
0001 : This is temporary!



Bump : 1.48
Date : 12-10-2013
Dude : megacz

Stat : BD
0001 : Disabled  ACTION_DISK_INFO completly due to bad implementation which
0001 : caused hits. The code was unusable anyway by most programs. This bug
0001 : showed up first in  Directory Opus 5 II  after device  list request.
0001 : This bug was found thanks to Stellan Pistoor who submitted  Enforcer
0001 : output.



Bump : 1.49
Date : 01-11-2013
Dude : megacz

Stat : BF
0001 : Fixed  FH  address checking. Please  note that  fm_fdcheck  does not 
0001 : point at fh_Func1 anymore, but instead at an array of 2  LONGs where
0001 : fh_Func1 of buffered and unbuffered FH live.

Stat : FA
0002 : Added  data-flush-per-write mode. This way buffered data will always
0002 : reach the destination without being stored until next write happens.
0002 : Activate with 'BF 2' on the command line.
