Commit 968b981b 968b981b080a2c84445de6bd0df67b265c5fdf28 by Sergey Poznyakoff
Options

Improve command line and error handling in pop3d. 

* pop3d/pop3d.h: Remove unused includes.
(ABORT): New state.
(pop3d_command_handler_t, struct pop3d_command): New types.
(pop3d_find_command): New function.
(pop3d_stat,pop3d_top,pop3d_uidl,pop3d_user,pop3d_apop)
(pop3d_auth,pop3d_capa,pop3d_dele,pop3d_list,pop3d_noop)
(pop3d_quit,pop3d_retr,pop3d_rset): Remove const from
the arguments. Functions are free to modify it.
(pop3d_parse_command): New function.

* pop3d/cmd.c: New file.
* pop3d/Makefile.am: Link in cmd.o
* pop3d/apop.c: Use pop3d_parse_command to parse commands
* pop3d/auth.c: Likewise.
* pop3d/extra.c (pop3d_args, pop3d_cmd): Remove.
(pop3d_parse_command): New function.
(pop3d_abquit): use pop3d_error_string to convert error numbers to
messages.
* pop3d/pop3d.c (cb_bulletin_db): Protect by #ifdef USE_DBM
(pop3d_mainloop): Change loop condition.
Use pop3d_parse_command to parse commands,
pop3d_find_command to lookup handlers in the command table
and pop3d_error_string to convert error numbers to
messages.
(main): Call enable_stls if necessary.

* pop3d/capa.c, pop3d/dele.c, pop3d/list.c,
pop3d/noop.c, pop3d/quit.c, pop3d/retr.c,
pop3d/rset.c, pop3d/stat.c, pop3d/stls.c,
pop3d/top.c, pop3d/uidl.c, pop3d/user.c: Remove const
qualifier from the command handler argument.
