The guts of this function doesn't need to be in server.c - it only uses extern server functions so it
makes sense just to move it into the body of function_servers(), the only caller.
That means it's no longer accessible for loadable modules, but it isn't much use for them anyway. They
can always directly access the server list if they need that info.
(Requires rolling the module table version).
When $myservers() is called with an argument of 1 it is supposed to only return the refnums of servers
that are registered (ie. those which it is legal to send a command to). This is the way EPIC works, and
it was always intended to work this way in BX too.
Also fix the warning about a NULL itsname - we use our name for the server if it isn't registered yet.
Remove the slightly bogus use of strncat() while we're here, by removing the temporary stack buffer and
just directly creating the result string with m_s3cat().
Remove the 'resend_only' flag option to fudge_nickname(). The only caller passing it was the CHANGE_NICK_ON_KILL
feature, and in that case it was the wrong thing too (and stopped that function from working at all).
Some other minor cleanups in fudge_nickname() while we're there.
Unset MSGLOG_FILE or CTOOLZ_DIR could cause a null pointer dereference.
If stat() failed it dereferenced the bogus 'struct stat', and in the directory case
just silently failed. Now it falls through to the "error opening" path.
This uses another bit in the existing flags argument in place of the command argument, and avoids
having to re-compare against fixed strings ("PRIVMSG", "NOTICE").
This allows building against recent libtcl versions.
A fallback definition of Tcl_GetStringResult() is included so that building against libtcl 7 still works.
This means the calling code in commands.c no longer needs to take a copy before calling the function.
Also remove code testing result of of ctcp_quote_it() and ctcp_unquote_it() - these functions never fail.
These functions are really specific to parsing and creating CTCP SED messages, which means they belong
in ctcp.c with the other CTCP code.
Also remove unnecessary inclusions of encrypt.h and ctcp.h.
Use size_t for passing buffer lengths, and const char * for encryption keys and other non-modified buffer
arguments.
Remove pointless helper function do_crypt().
Remove the inclusion of color.h from config.h, which is included by every file via irc.h, and instead
include it only in debug.c, fset.c and vars.c which are the only files that use it.
This minimises the number of files that need to be rebuilt when changing default format strings.
Encrypted messages to a channel need to use their own format. This also fixes the use of ENCRYPTED_PRIVMSG
and ENCRYPTED_NOTICE - they were being called with too many arguments so the destination nick was being prepended
to the message text.
Actual encryped messages and notices are now printed directly from do_sed() / do_reply_sed().
Inline CTCP replacement is only done if the message cannot be decrypted (for the [ENCRYPTED MESSAGE]
placeholder).
This removes the need for the global flag 'sed' to alter the NOTICE and PRIVMSG handling.
A side-effect of this is that SED PRIVMSGs now do not go through the usual PRIVMSG ignore
and flood handling. This is acceptable because messages can only go through this path if
the sender has actually been added as a SED peer with /ENCRYPT, and it still goes through
the CTCP ignore and flood handling.
When a SED-encrypted NOTICE is scanned for CTCPs within the decrypted portion, they should be
handled with do_notice_ctcp() so they are treated as CTCP replies.
kickcount is for counting KICKs sent by the user to detect KICK floods.
The userlist and isme() tests are already done prior to calling handle_nickflood() so they are
not needed here.
This flag is for tracking if we've sent a KICK for a nick. It means we can avoid
sending duplicate KICKs (eg for floods, channel protection etc).
MODULE_VERSION is bumped because NickList is a struct exported to modules.
This test is done quite a bit across the tree, and the open-coded variants make it easy to have an
accidental mismatch between the length of the prefix being tested and the length actually passed to
strncmp().
This fixes an issue of that type comparing the server version against the prefix "u2.10", where the old
code used an incorrect length of 4.
This table isn't modified or referenced outside of term.c, so it can be const static.
The 'const' moves ~20K from the data segment to the text segment (on 64 bit), reducing the total size of
the BitchX data segment by 10%.
Tokens that begin with two underscores __* or an underscore and an uppercase letter _X* are reserved,
so we should avoid those for our own include guards. The standard I'm settling on for foo.h is FOO_H_.
Also define STERM_C and include modval.h in scr-bx.c.
This allows us to remove the slightly bogus dummy definition of enum VAR_TYPES from modval.h, and use a simple
macro to redirect the declaration and use of get_int_var() to BX_get_int_var().
