ep TODO list
------------

Nepto [23/6/2002]
-----------------
- fix these program behaviours:
  - ep anything
  - ep anything --
  - ep anything -- anything

Nepto [27/5/2002]
-----------------
- cleanify support and contrib files in doc/ and test/
- config.h is created twice during ./configure script
- fix variables colision during compilation
  - global variable `index' is declared in string.h; it is function with same
    purpose as strchr() function)
  - global variable `link' is declared in unistd,h; type `man link' for more
    information about this function
- fix behaviour when non-existent binary to run name is specified; than will
  execvp() fails and returns (it is the same as ./ep -ii -oo -ee find ./)
+ 'make clean' does not clean objects in src/libcfg+/str/ subdirectory
  - Rajo, check if it is good

Nepto [9/4/2002]
----------------
+ proctable_wait2() seems to be the right function for child exit
  detection, but it needs testing and optimalization (variable scope,
  more clear code, ...)
+ write unblock implementation
  - resizing buffer from 5000 to 50 will work at least for few
    examples from file doc/problems.txt
* fix select(): bad filedescriptor in multiple cats
  - fixed, works fine; there was a really ugly bug in proctable_read() when
    process removing links to/from closed filedescriptor
- implement global configuration reloading and parsing

Wolcano [28/2/2002]
-------------------
* add '--help' command-line parameter

Nepto [28/2/2002]
-----------------
- ability to redirect whole config file input/output/errput

Nepto [21/2/2002]
-----------------
- solve case (un)sensitivy of process names ans make changes
  on appropriate places
- multiple config files and cooperation with command lien testing
- declaration & definition synchornization
- #include stuff synchronization
- conf.c: check if command (iow. what to run) is specified
- conf.c: structures freeing
- conf.c: check processes if they does not contain the same name before
  integration with proctable
- main.c: structures freeing on failures

Nepto [11/2/2002]
-----------------
- fix behaviour with empty process table
* make fd_str in fd.c static and add appropriate functions

Nepto [6/2/2002]
----------------
- handle Ctrl+C signal and terminate all processes than
- config file parsing via libcfg
- remove this cmdline parsing bug:
  ./ep -ii -o 2.i cat -- cat -o 0.i
- this will not properly exit on Ctrl+D (problem is with 0.e in process 2):
  ./ep -ii -o 2.i,0.o -e 2.i cat -- -o 0.e,3.i rev -- -o 0.o rev -- -o 1.i ps xf
  - sometimes it gets "Bad filedescriptor" failure
* time to go to sleep: Wed Feb  6 05:28:50 CET 2002 ;-)
* and this will exit only two childs (a little tip: there is probably a little
  problem in process destroying): ./ep -ii -o 2.i cat
                                   -- -o 3.i cat -- -o 4.i cat
                                   -- -o 5.i cat -- -o 6.i cat
                                   -- -o 7.i cat -- -o 8.i cat
                                   -- -o 9.i cat -- -o 0.o cat
  - tip was wrong: there is problem with synchronous I/O multiplexing; probably
    usage of exceptions flags should do the job
  - mistake was in the place of filedescriptors closing by my_close() function

Nepto [4/12/2001]
-----------------
* fix streamed programs bug (programs which are using C streams to access
  standart input/outputs doesn't work correctly)
  - finally, it is not a bug, but the feature (try in bash: rev | cat)
- allow to choose if n_link == 0 pipes will be only created and dup()-ed,
  or also than closed, or not closed but not fd_set-s, or fd_sets and ignored
* since now write all notes, comments, TODO items, etc. in english language

Nepto [3/12/2001]
-----------------
- Rajo sa zaviazal, ze do 5. februara popreraba vsetky ./configure skripty
  a Makefile subory, tak aby sa cely proces konfigurovania, kompilovania a
  linkovania viac stransparentnil a sprehladnil
* dalej by sa patrilo zistit, preco ked napisem './ep -i i -o o -e e cat'
  tak sa to sprava divne, tzn. niektore riadky mi to nevrati - pricom by mal,
  pretoze 'cat' to tak robi a my sme len medzi to postavili './ep' pri zachovani
  vsetkych filedescriptorov (fixed; Nepto)

Nepto [19/6/2001]
-----------------
- dlho sem nikto nic nedopisal

Wol [30/4/2001]
---------------
- bolo by vhodne keby vyvojari informovali help-writera, aby mohli byt
  helpy synchronne so sucasnym stavom (konkretne mam na srdci implementaciu
  konfiguraku)

Nepto [13/4/20001]
-----------------
- Wol nam jedol vtipnu kasu ;)
- je presne 01:56 am a ja idem implemetovat uplne novy command line parsing
  a config file parsing - z casti to uz mam urobene, ale bude to dlha noc...

Wol [11/4/2001]
---------------
- odstranit vsetky bugy (haha)

Nepto [4/4/2001]
----------------
- ked sa nejaky process neda vykonat (napr. chybajuca binarka, atd...), 
  tzn. ze zlyha execvp(), tak sa ukonci len potomok a svoju chybovu spravu 
  napise na svoj stderr a nie stderr ep, kam by to malo ist - treba fixnut,
  ale nemam potuchy, ze ako...

Wol [4/4/2001]
--------------
+ premysliet ako sa budu 'odfajkovavat' hotove veci v TODO (this document)
  (ten rajov sposob nieje moc pekny - neprehladny je)
  (Wol - 11/4/2001 - snad dostatocne - v kazdom pripade - mne sa to takto paci)
- premysliet dodatocne parametre k ep (--debug --version --help --no-menu)
  a ich skratene verzie a to neak VELMI rozumne

Wol [29/3/2001]
---------------
- navrhnut a realizovat koncepciu .eprc (heh)

Wol [28/3/2001]
---------------
- TOTO JE NEDOLEZITE :)) - koli rovnovahe s dolezitymi vecami :)) 
  (toto mozes zmazat)

Nepto [28/3/2001]
-----------------
- ked je vypnute menu, nelikovat s libncurses (DOLEZITE!)
- ked je vypnute menu, nekompilovat menu.c a m_*.c (TIEZ DOLEZITE!)

Wol [27/3/2001]
---------------
- spravanie sa EP pri zdochnuti niektoreho childu - minimalne tri urvovne:
	- 1. ignoruje a vsetky procesy bezia dalej
	- 2. spusti znova dany proces (a korektne napoji rury ! :) tak ako mali byt
	     predtym)
	- 3. bude mat zadany subor (napriklad) z ktoreho bude inkrementalne (a
	     cyklicky) citat prikazy ktore ma vykonat ak sa vykonavanie
         predchadzajuceho prikazu skoncilo ...)
	+ 4. posle SIGTERM (?) vsetkym procesom a ukonci svoju cinnost (s nejakou
	     hlaskou kde popise co ako preco a za kolko) (rajo, ?/3/2001)

Nepto [20/3/2001]
-----------------
+ zalohovaci skript
  (rajo, 3/4/2001) 

Nepto [15/3/2001]
-----------------
* menu musi podliehat podmienenej kompilacii, pretoze nie kazdy si ho bude
  chciet prilinkovat; zvlast potom, co som zistil, ze vysledna binarka s tym
  menu je trosku dost velka; sprav na to nejaku konstantu
  (rajo, 21/3/2001)
* na zdrojaky vytvorit samostatny adresar src/
  (rajo, 21/3/2001)

Nepto [13/3/2001]
-----------------
- spravit poriadne make menu
- zosynchronizovat Makefile na sirku 80 znakov (mala priorita) oddelit v
  zdrojakoch cast, ktora sa bude distribuovat, a oddelit cast ktora je pre nase
  interne potreby (napr. make backup, make menu, atd...)
- ked si skompilujem menu, stale mi to rozhasi terminal, takze by sa zislo
  make menu take, aby mi to terminal nesundavalo
* komentare sa pisu NAD funkciu... prosim Ta, nemyslim si, ze by to mal byt az
  taky problem dodrziavat a pis ich ako vetu. Zaciatok velkym pismenom a
  ukoncis bodkou. (rajo, ?/3/2001 - precitanuo)

Nepto [8/3/2001]
----------------
* zosynchronizovat menu.c tzn. spavit zdrojaky citatelne ale co je dolezitejsie
  a hlavne, aby funkcie mali nejaky system (napr. prefix)
  (rajo, 22/3/2001, pozn.: ved to uz bolo davno nie?? :-)
