A fractional-second timeout was already supported for the initial timeout of a /TIMER, but
if the timer was recurring then the interval was rounded to a whole number of seconds for
the subsequent timeouts.
Change the type of interval from long to double to fix this.
These globals were used to store the original terminal dimesions from the terminal database (or
in the case of reattaching, supplied by scr-bx) to be applied if the current terminal dimensions
could not be determined.
Instead, we leave the original terminal dimensions in current_term->TI_lines and current_term->TI_cols,
and create current_term->li and current_term->co to store the current terminal dimensions (as eg.
supplied by scr-bx).
With this change, the signal handler signature is defined in only one place.
Also make most signal handler functions static (those that are only referred to in irc.c).
CLOSING_SERVER was never referenced outside of server.h where it's defined, and CLOSE_PENDING was cleared
but never set by any code.
Rename LOGGED_IN to namespace it (in anticipation of other flag variables in the server struct being
consolidated into a set of server flags).
Also put correct parantheses around the definition of SF_LOGGED_IN.
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).
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.
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.
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.
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().
irc_std.h is where these belong - it's where the normal declarations (via the system headers) come from on
systems which don't need the compat functions.
This change means that struct.h no longer needs to include alist.h, so it will be indirectly included in a lot
fewer other files.
As a consequence, server.h needs to include notify.h to get the definitions of those data types.
init_socketpath() was building a sprintf() format string intended to be used by /DETACH to create the socket
file name. This included the actual socket path, plus a %d for the port, plus the sanitised tty name and
hostname.
Only one caller needed all this though - the /DETACH command - and the other callers (in scr-bx.c) just
wanted to truncate it to the actual socket path. The format string also wasn't safe - if the home directory
path, hostname or ttyname contained % characters these werent being escaped.
It simplifies things to have init_socketpath() just return the actual socket path, after creating the 'screens'
directory if necessary. This lets the code in scr-bx.c use it as-is, and removes the need for the global
socket_path variable. The code to include the sanitised tty name and hostname in the socket file name can
be moved to the create_ipc_socket() function.
There's no need to check access() for the socket path before trying to create it - just call mkdir() regardless,
since it will fail if the path already exists, which is fine.
This commit also adds error handling to the create_ipc_socket() function for the case where creation of the
socket file fails, and switches the chmod() and chown() for the opened file to the more appropriate fchmod()
and fchown().
The function provided (either by #define to the module table or directly in the case of scr-bx.c)
is called my_ltoa(), and the #define in irc_std.h aliases this to ltoa().
remove_channel() is only called in direct response to a message from a server,
so it always acts on from_server - remove the unnecessary server argument.
The channel argument is always non-NULL - remove the dead code that removed all
channels if a NULL channel was passed.
The declaration of dcc_dllcommands in modules.c was wrong - add it to dcc.h so it's checked against the definition in dcc.c
and include it from there.
The DCC_dllcommands structure isn't structured like a "List2" so remove_module() doesn't work - use remove_from_list_ext().
Using sequential constants for *_FLOOD constants means that we can use a simple lookup table to convert them
into text for display and IGNORE_* constants.
