As reported by Ancient, this is how it is documented to work. It's also how shitlist level 2 works, so
it's consistent this way.
Some other cleanups in check_auto() while we're here.
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).
Separate out the justification step of make_status() into a new function, so it can be wired in to
stat_convert_format() as well. This makes $statsparse() work correctly with right-justified status
formats.
Minimise the amount of copying around that is done during the justification - instead, we can just
remember pointers into the buffer returned by strip_ansi() for the left-hand-side, right-hand-side and
padding character.
Don't keep concatenating onto the same buffer with strlcat() when generating the padding - that gives
n^2 behaviour. Instead keep a pointer to the current end and concatenate there.
Ensure buffer is null-terminated before calling strlcat() on it, in stat_convert_format().
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).
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().
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.
Neither compat.c nor ircsig.c are compiled different for wserv or scr-bx, so there's no reason these
binaries can't just link to the same .o files as the main BitchX binary.
This also cleans up the build rules around wserv and scr-bx a little.
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().
The test for p != NULL is pointless, it has already been dereferenced and modified.
The argument to tolower() and toupper() must be in the range of unsigned char.
Fix some spelling errors in user-visible messages.
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().
Previously these codepaths were dead because it was passing an argument like "+HOST" to check_whowas_nick_buffer()
in place of the channel name, so it would never find anything.
Now that function supports a NULL channel to mean "any channel", so we can use that. The actual code itself needed to be
fixed as well, it's now similar to the way userhost_unban() is written.
The use of the whowas cache in userhost_unban() would never work, because it was passing 'args' as the channel
name which also included the window number.
Rework this substantially, including using lookup_channel() and set_display_target() in place of prepare_command().
