It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the `--target=TYPE' option to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/kopete/protocols/jabber/jingle/libjingle/Makefile.am b/kopete/protocols/jabber/jingle/libjingle/Makefile.am new file mode 100644 index 00000000..164f7058 --- /dev/null +++ b/kopete/protocols/jabber/jingle/libjingle/Makefile.am @@ -0,0 +1,4 @@ +SUBDIRS=talk + +dist-hook: + sed -i -f talk/sanitize.sed `find $(distdir) -type f`

+
+Libjingle is a set of components provided by Google to interoperate with Google
+Talk's peer-to-peer and voice capabilities. This package will create several
+static libraries you may link to your project as needed.
+
+-talk - No source files in talk/, just these subdirectories
+|-base - Contains basic low-level portable utility functions for
+| things like threads and sockets
+|-p2p - The P2P stack
+ |-base - Base p2p functionality
+ |-client - Hooks to tie it into XMPP
+|-session - Signaling
+ |-phone - Signaling code specific to making phone calls
+|-third_party - Components that aren't ours
+ |-mediastreamer - Media components for dealing with sound hardware and
+ | voice codecs
+|-xmllite - XML parser
+|-xmpp - XMPP engine
+
+In addition, this package contains two examples in talk/examples which
+illustrate the basic concepts of how the provided classes work.
+
+The xmllite component of libjingle depends on expat. You can download expat
+from http://expat.sourceforge.net/.
+
+mediastreamer, the media components used by the example applications depend on
+the oRTP and iLBC components from linphone, which can be found at
+http://www.linphone.org. Linphone, in turn depends on GLib, which can be found
+at http://www.gtk.org. This GLib dependency should be removed in future
+releases.
+
+Building Libjingle
+
+Once the dependencies are installed, run ./configure. ./configure will return
+an error if it failed to locate the proper dependencies. If ./configure
+succeeds, run 'make' to build the components and examples.
+
+When the build is complete, you can run the call example from
+talk/examples/call. This will ask you for your GMail username and your GMail
+auth cookie. Your GMail auth cookie is the GX cookie from mail.google.com
+found in your web browser.
+
+Relay Server
+
+Libjingle will also build a relay server that may be used to relay traffic
+when a direct peer-to-peer connection could not be established. The relay
+server will build in talk/p2p/base/relayserver and will listen on UDP
+ports 5000 and 5001. See the Libjingle Developer Guide at
+http://code.google.com/apis/talk/index.html for information about configuring
+a client to use this relay server.
+
+STUN Server
+
+Lastly, Libjingle builds a STUN server which implements the STUN protocol for
+Simple Traversal of UDP over NAT. The STUN server is built as
+talk/p2p/base/stunserver and listens on UDP port 7000. See the Libjingle
+Developer Guide at http://code.google.com/apis/talk/index.html for information
+about configuring a client to use this STUN server.

Behaviour if objects are +// destroyed concurrently is undefined (i.e. you'll get the occasional +// segmentation fault/memory exception). +// +// multi_threaded_global - Your program is assumed to be multi threaded. Objects using signals and +// slots can be safely created and destroyed from any thread, even when +// connections exist. In multi_threaded_global mode, this is achieved by a +// single global mutex (actually a critical section on Windows because they +// are faster). This option uses less OS resources, but results in more +// opportunities for contention, possibly resulting in more context switches +// than are strictly necessary. +// +// multi_threaded_local - Behaviour in this mode is essentially the same as multi_threaded_global, +// except that each signal, and each object that inherits has_slots, all +// have their own mutex/critical section. In practice, this means that +// mutex collisions (and hence context switches) only happen if they are +// absolutely essential.

States are pushed forward by +// pushing forwards a TaskRunner that holds on to all Tasks. The purpose +// of Task is threefold: +// +// (1) It manages ongoing work on the UI thread. Multitasking without +// threads, keeping it easy, keeping it real. :-) It does this by +// organizing a set of states for each task. When you return from your +// Process*() function, you return an integer for the next state. You do +// not go onto the next state yourself. Every time you enter a state, +// you check to see if you can do anything yet. If not, you return +// STATE_BLOCKED. If you _could_ do anything, do not return +// STATE_BLOCKED - even if you end up in the same state, return +// STATE_mysamestate. When you are done, return STATE_DONE and then the +// task will self-delete sometimea afterwards. +// +// (2) It helps you avoid all those reentrancy problems when you chain +// too many triggers on one thread. Basically if you want to tell a task +// to process something for you, you feed your task some information and +// then you Wake() it. Don't tell it to process it right away. If it +// might be working on something as you send it infomration, you may want +// to have a queue in the task. +// +// (3) Finally it helps manage parent tasks and children. If a parent +// task gets aborted, all the children tasks are too. The nice thing +// about this, for example, is if you have one parent task that +// represents, say, and Xmpp connection, then you can spawn a whole bunch +// of infinite lifetime child tasks and now worry about cleaning them up. +// When the parent task goes to STATE_DONE, the task engine will make +// sure all those children are aborted and get deleted. +// +// Notice that Task has a few built-in states, e.g., +// +// STATE_INIT - the task isn't running yet +// STATE_START - the task is in its first state +// STATE_RESPONSE - the task is in its second state +// STATE_DONE - the task is done +// +// STATE_ERROR - indicates an error - we should audit the error code in +// light of any usage of it to see if it should be improved. When I +// first put down the task stuff I didn't have a good sense of what was +// needed for Abort and Error, and now the subclasses of Task will ground +// the design in a stronger way. +// +// STATE_NEXT - the first undefined state number. (like WM_USER) - you +// can start defining more task states there. +// +// When you define more task states, just override Process(int state) and +// add your own switch statement. If you want to delegate to +// Task::Process, you can effectively delegate to its switch statement. +// No fancy method pointers or such - this is all just pretty low tech, +// easy to debug, and fast. +// + +namespace buzz { + +class TaskRunner; + +// A task executes a sequence of steps + +class Task; +class RootTask; + +class Task { +public: + Task(Task * parent); + virtual ~Task() {} + + void Start(); + void Step(); + int GetState() const { return state_; } + bool HasError() const { return (GetState() == STATE_ERROR); } + bool Blocked() const { return blocked_; } + bool IsDone() const { return done_; } + unsigned long long ElapsedTime(); + virtual void Poll() {} + + Task * GetParent() { return parent_; } + TaskRunner * GetRunner() { return runner_; } + virtual Task * GetParent(int code) { return parent_->GetParent(code); } + + // Called from outside to stop task without any more callbacks + void Abort(bool nowake = false); + + // For managing children + bool AllChildrenDone(); + bool AnyChildError(); + + +protected: + + enum { + STATE_BLOCKED = -1, + STATE_INIT = 0, + STATE_START = 1, + STATE_DONE = 2, + STATE_ERROR = 3, + STATE_RESPONSE = 4, + STATE_NEXT = 5, // Subclasses which need more states start here and higher + }; + + // Called inside the task to signal that the task may be unblocked + void Wake(); + + // Called inside to advise that the task should wake and signal an error + void Error(); + + unsigned long long CurrentTime(); + + virtual std::string GetStateName(int state) const; + virtual int Process(int state); + virtual void Stop(); + virtual int ProcessStart() = 0; + virtual int ProcessResponse() { return STATE_DONE; } + + // for managing children (if any) + void AddChild(Task * child); + void AbortAllChildren(); + +private: + void Done(); + void OnChildStopped(Task * child); + + int state_; + Task * parent_; + TaskRunner * runner_; + bool blocked_; + bool done_; + bool aborted_; + bool busy_; + bool error_; + bool child_error_; + unsigned long long start_time_; + + // for managing children + typedef std::set<Task *> ChildSet; + ChildSet children_; + +}; + + + + +} + +#endif diff --git a/kopete/protocols/jabber/jingle/libjingle/talk/base/taskrunner.cc b/kopete/protocols/jabber/jingle/libjingle/talk/base/taskrunner.cc new file mode 100644 index 00000000..b5ecc55e --- /dev/null +++ b/kopete/protocols/jabber/jingle/libjingle/talk/base/taskrunner.cc @@ -0,0 +1,92 @@ +/* + * libjingle + * Copyright 2004--2005, Google Inc. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * 1.
