From 4a455cfeea2decf9e979405f52c085593d50c18a Mon Sep 17 00:00:00 2001 From: aquanight Date: Sun, 21 Sep 2008 01:51:29 +0000 Subject: Make regex providers load correctly. Move m_rline to use the regex providers, and also move m_rline out of extras/. Document provider modules, and particularly the uselessness of . git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@10573 e03df62e-2008-0410-955e-edbf42e46eb7 --- src/modules/m_rline.cpp | 315 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 315 insertions(+) create mode 100644 src/modules/m_rline.cpp (limited to 'src/modules/m_rline.cpp') diff --git a/src/modules/m_rline.cpp b/src/modules/m_rline.cpp new file mode 100644 index 000000000..e6340cc0f --- /dev/null +++ b/src/modules/m_rline.cpp @@ -0,0 +1,315 @@ +/* +------------------------------------+ + * | Inspire Internet Relay Chat Daemon | + * +------------------------------------+ + * + * InspIRCd: (C) 2002-2008 InspIRCd Development Team + * See: http://www.inspircd.org/wiki/index.php/Credits + * + * This program is free but copyrighted software; see + * the file COPYING for details. + * + * --------------------------------------------------- + */ + +#include "inspircd.h" +#include "m_regex.h" +#include "xline.h" + +static Module* rxengine = 0; +static Module* mymodule = 0; /* Needed to let RLine send request! */ + +/* $ModDesc: RLINE: Regexp user banning. */ + +class CoreExport RLine : public XLine +{ + public: + + /** Create a R-Line. + * @param s_time The set time + * @param d The duration of the xline + * @param src The sender of the xline + * @param re The reason of the xline + * @param regex Pattern to match with + * @ + */ + RLine(InspIRCd* Instance, time_t s_time, long d, const char* src, const char* re, const char* regexs) : XLine(Instance, s_time, d, src, re, "R") + { + matchtext = regexs; + + if (!rxengine) + { + ServerInstance->SNO->WriteToSnoMask('x', "Cannot create regexes until engine is set to a loaded provider!"); + throw ModuleException("Regex engine not set or loaded!"); + } + + try { + regex = RegexFactoryRequest(mymodule, rxengine, regexs).Create(); + } catch (ModuleException& ex) { + ServerInstance->SNO->WriteToSnoMask('x', "Bad regex: %s", ex.GetReason()); + throw; + } + } + + /** Destructor + */ + ~RLine() + { + delete regex; + } + + bool Matches(User *u) + { + std::string compare = std::string(u->nick) + "!" + u->ident + "@" + u->host + " " + u->fullname; + + ServerInstance->Logs->Log("m_rline",DEBUG, "Matching " + matchtext + " against string " + compare); + + if (regex->Matches(compare)) + { + // Bang. :D + return true; + } + + return false; + } + + bool Matches(const std::string &compare) + { + if (regex->Matches(compare)) + { + // Bang. :D + return true; + } + + return false; + } + + void Apply(User* u) + { + DefaultApply(u, "R", true); + } + + void DisplayExpiry() + { + ServerInstance->SNO->WriteToSnoMask('x',"Expiring timed R-Line %s (set by %s %ld seconds ago)", this->matchtext.c_str(), this->source, this->duration); + } + + const char* Displayable() + { + return matchtext.c_str(); + } + + std::string matchtext; + + Regex *regex; +}; + + +/** An XLineFactory specialized to generate RLine* pointers + */ +class CoreExport RLineFactory : public XLineFactory +{ + public: + RLineFactory(InspIRCd* Instance) : XLineFactory(Instance, "R") { } + + /** Generate a RLine + */ + XLine* Generate(time_t set_time, long duration, const char* source, const char* reason, const char* xline_specific_mask) + { + return new RLine(ServerInstance, set_time, duration, source, reason, xline_specific_mask); + } +}; + +/** Handle /RLINE + * Syntax is same as other lines: RLINE regex_goes_here 1d :reason + */ +class CommandRLine : public Command +{ + std::string rxengine; + + public: + CommandRLine (InspIRCd* Instance) : Command(Instance,"RLINE", "o", 1) + { + this->source = "m_rline.so"; + } + + CmdResult Handle (const std::vector& parameters, User *user) + { + + if (parameters.size() >= 3) + { + // Adding - XXX todo make this respect tag perhaps.. + + long duration = ServerInstance->Duration(parameters[1]); + RLine *r = NULL; + + try + { + r = new RLine(ServerInstance, ServerInstance->Time(), duration, user->nick.c_str(), parameters[2].c_str(), parameters[0].c_str()); + } + catch (...) + { + ; // Do nothing.
