This also makes the "forced nick change" message a bit more
generic, leaving out the "by services" or "due to Services",
since it is now possible to do it via JSON-RPC.
not a format string (eg ":%s LUSERS %s"). It now simply concats all parv[]'s.
That is, up to parc count. And it automatically does the :stuff for the
last parameter if it contains spaces or starts with a : etc.
This gets rid of a bit sketchy code with an arbitrary maximum etc.
Now it's just:
if (hunt_server(client, NULL, "REHASH", 1, parc, parv) != HUNTED_ISME)
return;
This has one side effect, though:
Previously we used the format string, so it may be possible for S2S
traffic to now have more arguments then before here and there.
Eg:
* It could be that the caller was using a format string to
intentionally cut off an extra parameter at the end.
You can still do that if you call with eg parc-1 instead of parc.
I don't think there were any such cases though, but hard to rule out.
* Extranous parameters may show up in S2S traffic where it was
previously unexpected.
It means you can no longer modify eg parv[1] in-place with strtoken and such.
The main reason for this is that as a command handler you have no idea
where the arguments may come from. It could be from a do_cmd() with
read-only storage (eg a string literal) and so on.
It started with an experiment of how far I could get and how annoying the
side-effects would be, but they seem to be quite managable, so I'm
committing this stuff.
Hopefully this catches/solves some stupid bugs somewhere :)
I forgot to include message tags earlier, so this is a breaking change:
-int hooktype_local_nickchange(Client *client, char *newnick);
-int hooktype_remote_nickchange(Client *client, char *newnick);
+int hooktype_local_nickchange(Client *client, MessageTag *mtags, char *newnick);
+int hooktype_remote_nickchange(Client *client, MessageTag *mtags, char *newnick);
Be sure to update your hooks!
You can use something like: #if UNREAL_VERSION_TIME>=202115
Eg with anope with the KILL option turned ON, a minute after taking
a registered a nick.
Very similar to c9b88343e2 which was
fixed in 5.0.0-beta1 for non-forced nick changes.
This so I - and others - don't constantly have to wonder whether the client
is called sptr, cptr or acptr in a simple routine.
Insane --> 212 files changed, 6814 insertions(+), 6945 deletions(-)
Couldn't just mass-replace of course since there are places where there
are multiple clients involved. So had to check each function.
Also renamed some 'acptr' to 'target' and such.
I will write a page with new style rules later.. but in short if there is
only 1 client involved it will now be called 'client'.
code changes in UnrealIRCd itself:
1) Clients are no longer freed directly by exit_client. Most fields
are freed, but 'sptr' itself is not, so you can use IsDead() on it.
2) exit_client now returns void rather than int
3) ALL command functions return void rather than int.
Of course this also affects do_cmd, command overrides, etc.
This is a direct consequence of the removal of 'cptr' earlier, as that
was used to signal certain things that are now no longer possible
(and it raises the question if things were always correctly signaled
in the first place, so may fix some bugs).
It also makes the code more resillient against cases where you forgot
to check if the client was freed. Still, you are encouraged to do an
IsDead(sptr) if you are calling functions that may kill clients,
such as command functions or things that may use spamfilter.
More changes will follow, such as the removal of FLUSH_BUFFER.
** Exit this IRC client, and all the dependents (users, servers) if this is a server.
* @param sptr The client to exit.
* @param recv_mtags Message tags to use as a base (if any).
* @param comment The (s)quit message
* @returns FLUSH_BUFFER is returned if a local client disconnects,
* otherwise 0 is returned. This so it can be used from
* command functions like: return exit_client(sptr, ....);
'sptr' is sufficient and in most cases the only one you should care about.
Should you need it, you can access sptr->direction in cases where you
need the old information (usually only for some sendto_* functions
and some protoctl checks), so 'cptr' was redundant too.
[!] This change likely introduces some bugs. This was many hours of work.
I only cut some corners in 4 functions, which will be fixed at a later
stage..... yes, more major changes to come.
On the plus side, I likely fixed some bugs in the process. Situations
where cptr vs sptr usage was incorrect. Eg using cptr->name (near server)
when sptr->name should be used (the actual source server), etc....
MOD_UNLOAD. And MOD_HEADER(xyz) is now MOD_HEADER even without ()
since this isn't a function, really.
To make things understandable I added the following to the
developer section of the release notes:
* The module header is now as follows:
ModuleHeader MOD_HEADER
= {
"nameofmodule",
"5.0",
"Some description",
"Name of Author",
"unrealircd-5",
};
There's a new author field, the version must start with a digit,
and also the name of the module must match the loadmodule name.
So for example third/funmod must also be named third/funmod.
* The MOD_TEST, MOD_INIT, MOD_LOAD and MOD_UNLOAD functions no longer
take a name argument. So: MOD_INIT(mymod) is now MOD_INIT()
aChannel to Channel, and some more. Third party module coders will
love this. But.. it makes things more logical and the doxygen output
will look more clean and logical as well.
(More changes will follow)
and remove old dependency field (never used, was always NULL,
broken since 3.2.x)
I'll add some constraints later on things like names and versions.
IOTW: more changes to follow, don't mass update your own mods yet.
So rename src/modules/m_*.c to src/modules/*.c and update makefiles
and modules.default.conf. Also remove m_ at various places in the
source files, but not the CMD_FUNC(), just the module name.
