The ZThread package is an advanced object-oriented, cross-platform, C++ threading and synchronization library that has been designed and implemented by the author and released under the MIT license. It provides a high level abstraction of the native threading mechanisms to offer a great deal of flexibility and control. This software features interruptible Thread and Runnable objects for C++, control objects and implementations of concurrency design patterns. This includes semaphores, mutexes, condition variabes as well as other more complex components. Existing threading APIs do not provide a consistent and portable means for exercising control over concurrently executing software. Thread cancellation and termination is one example of this complexity. ZThreads includes an elegant method of safely terminating threads without the complications of using cancellation handlers or other similar constructs. This is a platform independent architecture that was designed by the author. Implementations have been provided for POSIX and Win32 platforms. Building this library was quite different for POSIX than it was for Win32 due to the nature of the functionality each platform naturally provides; each platform had strong and weak points. They were used to create the most flexible and efficent abstraction possible. The result is an excellent software layer on which to build mutlithreaded code. LICENSE: This source has been released under the MIT license. See MIT.TXT for details regarding the license. You can you use this in closed source projects, contact me if you need to discuss a different licencing. COMPILING: ZT_POSIX, ZT_WIN32 should be defined to specific what platofrm your building on this. This is mainly so the right modifiers can be placed on class and function definitions to export things from a DLL properly if your using the WIN32 implementation. If you leave these flags out ZThreads will try to guess. See BUILDING for more details. NOTES: Please report bugs to me via email, I don't monitor the bug tracker or the forums on sf. HISTORY: So far, this library has been tested on MacOS X, Linux, Tru64 Unix, Win95, Win98, WinNT, Win2k, WinXP, SunOS, and FreeBSD.

(Caused hanging in some cases and general trouble with CountedPtr) Added configuration option to prefer vanilla implementation where possible. Fix to Barrier (by Michael Doppler) Fix to Thread joining implementation Fix to BiasedReadWriteLock VERSION 2.3.1: Bug with PoolExecutor/ConcurrentExecutor not automatically canceling themselves properly. VERSION 2.3.0: I've been working on some updates after working with Bruce Eckle and Chuck Allison; who've provided quite a bit of valuable feedback VERSION 2.2.11: Adjusted some of the include files that were missing #include's that were left out (Barrier.h, ZThread.h, posix/FastMutex.h) Fixed some of the Time class's math. FairReadWriteLock should properly release waiters. DeferredCancelationScope defers cancelation correctly now as it should. Started updating the autoconf files, detects asm/atomic.h and bits/atomicity.h correctly now. VERSION 2.2.10: Rolled up most of the small changes that were available in CVS. BlockingQueue was out of date; there was some deadlock potential in the Monitor classes that was removed, the AtomicCount needed the dll export decoration, and a few other miscellaneous updates. VERSION 2.2.9: Updated ThreadQueue which mistakenly was not removing joined daemon threads. Updated Win32 SwitchToThread code. VERSION 2.2.8: Added MacOS support. This has been tested with MacOS X only Updated BoundedQueue.h Updated the vannila primatives VERSION 2.2.7: Apply user submitted patch to remove non-nothrow exception specifications. The patch can be found (and reversed if desired) in the contrib/ directory included in Singleton Enabled CVS Updated read-write lock interface. - Dropped RWLock, moved to ReadWriteLock - Adjusted implementation of the two concrete subclasses. VERSION 2.2.6: Type in FastLock.h fixed. VERSION 2.2.5: Added an AtomicCount class that will use as lightwieght a locking mechanism as possible. This class is used for limited reference counting and is typically not under high contention. VERSION 2.2.4: Added mutex implementation for Win32 that will use a normal Mutex object; this will perform better under high contention. Added a smarter yield function for Win32 implementations; this will kick in on NT (or better) and will operate a bit more intelligently than Sleep(0) Fixed a typo in LockedQueue Made Thread::Reference public, most compilers did not complain - gcc 3.0+ didn't like it private. Renamed ZTHREAD_USE_NATIVE_LOCKS to ZTHREAD_USE_SPIN_LOCKS since that is more descriptive of whats going on when that is defined. VERSION 2.2.3: Added a ThreadedExecutor. Added a template to create Futures. Suggestions to improve the syntax welcome Fixed some of the compiling errors in the tests & examples I had not updated since I made some changes to the library during this last week. updated. If you have good examples, or test programs of your own please send them to me. I'd like to add some decent examples for using ZThreads but I don't have much free time right now. VERSION 2.2.2: Added Handle that removes ownership concerns for Runnable objects. Thread changed to support it. VERSION 2.2.1: Added correct destructor to Queue. Changes to the Thread class, this should help eliminate confusion about interruption. (See guide) Killing removed, replace with Cancelable semantics that are based on interruption. (See guide) Added a guide for using threads, runnables & interruption Finished CancelableTask Added a guide for using Threads and Runnables to the Thread documentation Documentation Updates: - Thread - CancelableTask Removing Future, letting the other changes settle down for a little while, while I take time to explore that a little more. Hopefully, the additional documentation is helpful. VERSION 2.2.0: *knock, knock, knock* Housekeeping! - Code cleanup, test cases and more documentation. The goal here is to make the basic parts of the library independant from the rest, helping to make a more concrete code based to build some new abstractions on. Cleaning up the dependancies between the various sources, added better detection for the implementation selection and simplified whats required to build the library in general. This will make it easier to expand on the library as a whole, and it will make it easier for others to use in different make utilites. Decoupled alot of the implementation specific code from the wrappers for the library. Added several FastLock implementations and a VannilaRecursiveLock. People adding support for (MacOS for example) should have an easy time creating a FastLock, each lock uses a different strategy to serialize access, so they should server as a nice template. Added test cases for the various primatives ZThreads uses. This helps debugging and should help people creating primatives for new platforms. Adding support for new platforms should be _very_ easy. I will include a guide for how to do this. I've had many requests for MacOS support and for BeOS support, unfortuneatly I don't have a Mac & I don't have time to play with BeOS or Darwin. I hope the guide will help some kind soul to contribute the few small classes that are required to extend this library to support a few more platforms. OR if you would like to contribute an actual Mac and save yourself some work, that'll work for me too - I promise I'll add support to a platform if you give me one :) Simplified exception classes, helps support error reporting from Futures (new feature discussed below) Cleaned up autoconf scripts, I will probably still maintain VS6 project files (eventaully VS7 when I get a computer that handle it, my 2K box is old) but I'm trying to move mainly to autoconf. * autoconf should be able to use vc to compile & link. I've had moderate success (I can compile using msvc with autoconf & cygwin, but have trouble linking) it would be nice to have autoconf handle that. I'm looking for help getting that fixed & for getting autoconf to build on cygwin with gcc as well. I don't have enough free time to really invesitage that myself. Changed the semantics of the Condition to make its correct usage clearer. Documentation will discuss the changes. The library can also be configure through the zthread/Config.h file. Remvoed the need for certain objects to be static ----------------------------------------------------------------------------------- New things, * PriorityMutex, PriorityInheritanceMutex * PrioritySemaphore * PriorityCondition * Barrier (revised) * Time * Futures * ThreadFactories * CancelableTasks * Enhanced Executor framework * Enhanced ThreadLocals * Waitables Exposed the Time class, which offers relative time values with millsecond resolution. Added destroyValue() to AbstractThreadLocal, called when a thread that has set values on a ThreadLocal is about to exit. Improved daemon thread handling. Daemon threads that have compelted can be removed sooner. Daemon threads creating other daemon threads will not cause an error. Added template methods to Condition that allow a wait on predicate. Guard template greatly refined. Quite versitle, I hope to write a short article to explain more fully. The syntax is the same, so code using the Guard from previous versions should not be affected. Synchronization policies deemed uncessarry and removed. It's much better to simply parametize the locks, allowing the user specified lock to be the policy. Policies are much more awkward than a parametized template for that purpose. This change only affects 2 templates. TypedLockables not really neccessary w/o syhcronization policies, replaced with the more useful ClassLock that can be used as a parametized type to create a class-wide lock. LockableAdpater also removed. Scraped Observable and Timer classes. Moved the Observable class to the contrib/ directory. It was interesting, but it was not very flexible and surprizingly less useful that it seemed. Introduction of the Time class should make it far more effective for people to create thier own Observable classes that will be more robust.. Thread priorities now on by default, and there new PriorityXXX classes that take advantage of priorities. Dropped SharedInstance support in favor of the SmartPtr. The SmartPointer is really just an example of how something like that can be made with ZThreads. Revised the Barrier class to act more like a Barrier should. Futures introduced. Future act as a placeholder for a value that may not be available yet. NullMutex renamed NullLockable to reflect its purpose better. SimpleQueue removed, a LockedQueue with a NullLockable is equivalent Killed_Exception replaced Unexpected_Exception Removed SmartPtr, reverted back just the IntrusivePtr and CountedPtr. Those are simple and are all the library requires. I don't want repeat the work that has been done by groups, such as boost, to try and provide a set of smart pointers that works across all compilers. Executor greatly improved. ----------------------------------------------------------------------------------- Documentation Updates: - Cancelable - Waitable - Lockable - Time - Queues - FastMutex, Mutex, PriorityMutex, PriorityInheritanceMutex - FastRecursiveMutex, RecursiveMutex - Condition, PriorityCondition - Semaphore, PrioritySemaphore - ThreadLocal - Barrier - Executor Added Design Overview Added Porting Guide Added Executor Pattern (pending) Futures almost complete, still need to update the interruption hooks - I made so many changes I wanted to put the new release out and get some feedback. VERSION 2.1.6: Maintence to the Mutex, Semaphore & Monitor classes. VERSION 2.1.5: Eliminated race condition when starting daemon threads. Removed dllexport/dllimport decorator from some policy classes to avoid unresolved symbol errors when exporting some classes from dll on Win32 Adjusted order of constructors in StaticSingleton so the cleanup function doesn't need to be registered with atexit. Changed the IntrusivePtr so it works with the Synchronization policies provided. Added throw() to the destructors of example classes that required it. void* _dispatch(void*) moved into namespace ZThread in POSIX_ThreadOps.cc explicit typenames added to Observable where required VERSION 2.1.4: Refined the Guard template to allow policy to control its behavior keeping the interface compatible with the previous Guard implementation. Removed const-ness of the notify method for Observable objects. Applied new Guard and policies to Observable, restoring the serialization of the 2 argument notify method (fixing the Timer) Added policies to Singleton VERSION 2.1.3: Minor update for win32 build. Just a few adjustments so it build correctly under MSVC. VERSION 2.1.2: Unused daemon threads no longer cause assertion failure. LOCK templates renamed to LockType to avoid collisions with LOCK symbols defined in some linux headers. Added a TypedLock Added ClassLock policy for SmartPtr. Updated Timer. VERSION 2.1.1: Fixed a race condtion in the ConditionImpl. VERSION 2.1.0: Updated the autoconf configuration to allow windows or posix version to be be selected. Documented all the build flags, see BUILDING Changes to the implementation to make things more general, robust and easier to maintain. Exploring a more tightly synchronized implementation whose logic is simpler than the loosely synchronized versions in 2.0.X. VERSION 2.0.5: There was an error in the way threads were being started, the parent thread was waiting on the childs monitor, which shouldn't happen, and if the child's yeild() didn't return control to the parent before the child continued, then deadlock could occur. Updated tryAcquire()'s & join() with timeout, to help account for phantom signals that could be sent in some circumstances. Update the timed wait on ConditionImpl which was erroneously returning true. My next task is to reevaulate the monitor solution once again and see if there is a way to improve the monitor itself to reduce the complexity of the synchronization objects. Probably, using more traditional monitors will be more helpful - the main purpose of the new implementation was to join together the logic for the synch objects so that future changes could be made more easily. VERSION 2.0.4: Added a random stress option that is used to assist in testing the library and ensure the 3 basic synchronization objects are correct. It works by inserting random sleeps wherever there is a lack of atomicity. Fixed the errors made in the synchronization logic in the last release. Fixed a typo resulting from my notoriously bad spelling in Timer. VERSION 2.0.3: Updates to Timer. Updates to ConditionImpl. VERSION 2.0.2: Updates to the some of the #defines for Windows platforms Updates to the synchronization objects implementation. Updated executors docs somewhat, I didn't realize how unclear the documents were I wrote them two years ago :) SynchExecutors will consume tasks now by default, unless you specify otherwise using the template parameter. This makes all the Executors behave similarly. VERSION 2.0.1: Settled on all the changes for the 2.0.X series, this will be the first stable 2.0.X release. Removed CheckedMutex, Mutex now throws Deadlock_Exception in order to increase usability. The newer monitor implementation for to control the threads & interruption allowed me to merge alot more of the code together for the POSIX & WIN32 implementations; which makes this much easier to maintain. Gradually, I'll probably begin to do this will the thread & threadlocal implementations as well. This newer implementation also deals with some of the subtle synchronization errors in the 1.0.X version. After having learned Win95 does not support the InterlockedComparExchange() function an alternate spin lock implementation was added for people who need support on that platform (FastMutex classes). VERSION 2.0.0d: Removed the overlapped locks in release(), eliminating that potential deadlock. VERSION 2.0.0c: Timeouts of 0 are now correctly treated as 0 instead of infinite waits. Updates for Conditions. Fixed all tryAcquire()'s VERSION 2.0.0b: Small fix in the Win32 kill(), notify() instead of interrupt(). Custom spin lock was added for the FastMutex & RecursiveFastMutex Win32 implementations - apparently, TryEnterCriticalSection() does not work at all on some windows platforms. Misc project adjustments, (defines etc). VERSION 2.0.0a: POSIX & WIN32 implementations now function quite similarly and will simpler to maintain. Revised the primatives for both Win32 & POSIX implementations, check the docs for changes in Mutexes, Conditions & Semaphores. These updates address subtle synchronization problems in the original implementation as well as usability in general. Timer values relative to time library loaded, to avoid overflows. Reimplemented Threads join() is interruptable & has optional timeout - see docs kill() is more reliable - see docs misc updates that address previous implementations subtle errors Fixed BlockingQueue cancel() method. Fixed ThreadManager sending interrupt() to threads no longer running when wantNotify() was true. Reimplemented ThreadLocals More detailed documentation. VERSION 1.5.4: Fixed a bug in Win32_MutexImpl.cxx, and Win32_RecursiveMutexImpl.cxx. The waiter lists were erroneously decremented in some cases, which caused some mutexes to never unlock. Fixed the subtle race condition in the POSIX_FastRecursiveMutex implementation. The power went out for 48 hrs so I was un-busy enough and came up with something I think will fix it. Updated a documentation error. Updated Timer.cxx so that Timer::now() returns more accurate millisecond timing. Updated Win32_ThreadManager to be more stlport friendly. VERSION 1.5.3: Fixed a bug in WIN32_ThreadImpl.cxx that caused Thread::sleep() to throw Synchronization_Exception instead of Interrupted_Exception. Fixed a bug in MonitoredQueue that threq NoSuchElement_Exception rather than Timeout_Exception. Fixed POSIX_ThreadImpl.cxx, ThreadImpl::wait(...) The timing for the POSIX implementation should be better now. It now spends far less time playing with time values so it is more acurate. VERSION 1.5.2: Updated executor templates to allow for a little more flexibilty. You can now just plugin a new queue or lock implementation rather than having to subclass the AbstractExecutor and reimplementing an Exector when all you really neede to change was the queue. Updated templates to help compilers that were having trouble generating default values for static members. Updated time-math in the thread implementation - nanoseconds are measured in billionths now as they should be instead of in millionths. Added EXTRA_CXXFLAGS and EXTRA_LDFLAGS to the build files so that users can customize the build. For example, make "EXTRA_CXXFLAGS=-my-compilers-flags", etc. Removed unneccessary 'using namespace std' statements. More friendly for people using various STL implementations which have std::fatal & std::abort defined. That overlap caused ambiguity errors when the using statements were present. VERSION 1.5.1: Updates to misc. throw() specification errors that some compilers caught Small update to Win32 project files VERSION 1.5.0: Simplified templates (Executors, etc) avoids multiple definition error when linking Timer error fixed Misc bugs (minor) in Win32 implementation repaired. Moved old Mutex to PlainMutex, replace with a Mutex that can be interrupted which is more useful in general. For most cases the FastMutexes can be used in thier place when the user desires no interruption Added a couple contributed header for disabling warning with VC, you can use them to disable warnings in general for visual c's handling of stl symbols. (optional - vc specific) VERSION 1.4.4: Fixed bad throw clauses in the examples that gcc 3.0 choked on. Updated templates to include a default template with a specialzation for daemon threads, resolves alot of problems with compilers generating the code for those tempalte multiple times. VERSION 1.4.4: Fixed bad throw clauses in the examples that gcc 3.0 choked on. Fixed typo with #ifndef/#define in Win32_FastRecursiveMutex.h Corrected documentation for AutoPtr Improved the GNU autoconf/automake builds (again). - Added '--enable-examples' option to configuration - Updated configuration files to with libtool 1.4, the older ltconfig cause some problems with some systems. - Fixed the 'distcheck' rule. VERSION 1.4.3: Moved the headers to a more standandard directory, everyone asked me for it. Fixed a timeout oversight the ThreadImpl. - Blocking with a timeout was not responding correctly. - Added one more thread state, JOINING. Prevents multiple joins, while allowing the rest of the logic to function correctly. Improved the GNU autoconf/automake builds. - Added 'make rpm' - Added 'make docs' - Fixed 'make dist'; previously, I had intended ppl only to use 'make' & and 'make install' - You learn more about autoconf every time you have to update this stuff. Good tool, big learning curve :) VERSION 1.4.2: Fixed a typo in the AutoPtr class template VERSION 1.4.1: Added a pthread.m4 macro, Updaed other misc build files Fixed some errors with the throw clauses on Worker & InheritableThreadLocal Fixed the Timer class which has been overlooked since the improvements to managing static object were made VERSION 1.4.0: Make more distinct the change in kill() and other behavoir in the last few version. VERSION 1.3.5: Enchanced the ThreadLocal variables. Updated & simplified FastMutexs. VERSION 1.3.4: Revised the implementation classes a bit. Revised the Worker class so it can be canceled/killed without having effects on executing tasks. Added new/better support for killing threads Added more comments to the implementation classes VERSION 1.3.3: Non-realtime thread priorties, prelimary support VERSION 1.3.2: Updated subtle bug with threads starting up on some posix systems. Updated errors in the Win32 semaphore classes. Updated redudancy is in the POSIX semaphore classes. Converted Barrier & Latch to more appropriate template classes VERSION 1.3.1: Updated errors in Win32 build files Updated the Observable template to be friendly with more compilers VERSION 1.3.0: Updated compilation bug in Win32 dynamic build. That build will compiler correctly again and the dll version will have the same behavior as all other builds, making things more predictable. Updated executor classes to make room for reusable task objects and a little more flexibility VERSION 1.2.4: Fixed an oversight in the documentation configuration file and the Timer.cxx, I released 1.2.3 just a little too hastily :) VERSION 1.2.3: Updated WIN32 & POSIX Thread management Bug fix in WIN32 thread wait() routines Added daemon thread support for static objects VERSION 1.2.2: Factory template added Added support for handling static destruction problems VERSION 1.2.1: Fixed subtle bug in POSIX_ConditionImpl Upated all classes - misc changes VERSION 1.2.0: Updated much of the implementation classes for the synchronization objects. Much faster, and reduced contention. Updated the Cancelation interface Updated all classes using the Cancalation interface VERSION 1.1.3: Spell checked the documents (tedius) Bug fix in Barrier.cxx Bug fix in WIN32_FastRecursiveMutex.cxx Bug fix in WIN32_ConditionImpl.cxx Cleaned up the System & ThreadImpl interactions Cleaned up POSIX & WIN32 ThreadImpl classes Updated Documentation (noticable change) Updated ThreadLocal classes Updated ThreadImpl classes Miscellaneuos updates to make some class definitions for formal (addition of needed throw() clauses, etc) Had some testing on Tru64 unix that was posative VERSION 1.1.2: Bug fixes in the Thread class. I had overlooked that reference Thread objects (eg from Thread::current()) were deleting the thread implementations mistakenly Added a very usful Observable template Added timer classes There might be several other bug fixes I forgot to document completely, most of this work was done because I was using Zthreads in creating another application so I just fixed and enhanced the library as was appropriate Also, there are now static & shared library builds for all supported platforms VERSION 1.1.1: StaticSingletion template was added This is another build update, the library will now install so it is much easier to use way. Versioned shared libraries were also added using libtool. You can link against the shared library, or your can link against the .la file in build directory A 'zthread-config' script was also added to help other write configure scripts that look for various versions of the library Some very useful information for the autoconf tools that helped can be found at the following URL http://www.murrayc.com/learning/linux/building_libraries/building_libraries.shtml#RecommendedReading VERSION 1.1.0-2: This release basically include some packaging fixes. The autoconf scripts generate Makefiles now that link with -pthread instead of -lpthread on FreeBSD VERSION 1.1.0-1: Someone used BoundsChecker and caught a small memory leak that was fixed. There was an '==' where a '!=' was needed. I wish I could include thier name, but when my university email account was closed it ate all my old email so I ended up losing that corespondance VERSION 1.1.0: This release has many changes. For one, I have tightened up the exception classes. This makes the exceptions easier to handle, the code in general, easer to read. The exceptions can carry useful information now where as before they were just objects of different types being thrown Some exceptions have been removed because they were reduntant Thread priorites have been remove because I don't feel there is a good reason to have them. Thread priorities act differently across all machines, and my goal in creating this library was to build a usable archtechure for controlled predicatable multithreading. Thread priorites don't fit in. Runnable objects return void now. There is no need to a runnable object to return a value. I felt this was an uneeded complexity. Enough has been provided in this library to have the results of task run by other threads commincated in a number of better ways than a return value. A ThreadLocal object was added to provided access to local thread storage. This is very much like Java' ThreadLocal object. All of the basic synchronization objects have been improved. Several new ones have been added whose purposes are straitforward. The implementation of the this package was revised and refactored. There is no longer a need for a SyncFactory, and a whole layer of virtual function calls was also removed. This increased the speed and elegance of the code. The ThreadImpl classes were also better encapsulated. The Thread class is now extendable and you can use pretty much just a like a Java Thread. The queue classes have all been updated. I think there may even be one more than before. I have refined these queue classes as the executor pattern I was using improved. I added a 'Cancelable' interface to these objects hopefully I will have the time to write a small paper on the pattern to fully explain it. Most of the executor pattern I improved in java and I just recently updated zthreads to reflect this. I may relese a java supplement to the library shortly. I find that java is very useful when expirementing with different types of patterns. ZThread-2.3.2/INSTALL0000644000175000001440000001744307507342257011051 00000000000000Super Basic Installation ======================== ./configure && make and through the power of automagic everything should compile fine. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. 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, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). 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 at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' 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. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure 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 supports 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' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM 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 host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. 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. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--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. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options.

Want to simplify keeping a reference to threads outside the scope of the function requesting one. 06-01-2002: The only thing that I' planning on finding a better solution for is that passing of Runnable objects. I have some strict rules about ownership, right now - but even that seems a little too awkward. I'd like to make this automatic, perhaps using a kind of reference counting. I just haven't had time to fully evalute things yet. 05-27-2002: Possibly revise ThreadOps to act as an identifier for a native thread. 05-26-2002: Cleanup dependancies 05-14-2002: Consider making Singleton return references instead of pointers. 05-13-2002: Re-evaluate the policy templates. Update to make more usable, remove the template method work around if possible. Consider making ThreadLocals clear()able - removing all mapped values to simplify the task of those using the PoolExecutor. (keeping stale values from interfering with tasks) Consider adding Futures as described by Doug Lea. Possibly make the Observable class have some paramatized type that controls weather the listeners should be copied and notified, or if the lock should just be held throughout notification - weather this is helpful or not depends on how long the listeners usually take. Executors could be a good candiate for policies. 04-26-2002: Explore some of the updates to Doug Lea's concurrent package. Find someone familar with mingw32/cygwin to help adjust whatever details are needed to compile correctly there, I've gotten the autoconf scripts setup but there are a few things that still need to be worked out. 04-24-2002: - Possible Timer enhancements - Add a small allocator for tiny obejcts, like TimerEvents - Make Timer use const TimerEvent pointers instead of id's. - Replace the used key set added to the timer with a user supplied id generator. 02-20-2002: Possibly add a cleanup thread that joins daemon threads sooner. 02-07-2002: Add a test suite, should have done this a long time ago - but have been busy :) At least for some common problem situations. *DONE* Consider using an InstanceLock for the IntrusivePtr extended by Thread to aliviate contention. *DONE* I need to start using a real make for windows that will work with ms compilers. DevStudio is next to useless. *DONE* Had to make the Event used to block threads have a non-recursvie lock due to that type of lock not being 100% reliable on some POSIX system. Should update the WIN32 implementation to also no rely on the recsiveness of the CRITICAL_SECTION it uses to ease maintenece. *DONE* Find some better Win32 build method for Visual Studio. - Suggestions very welcome for this Check cygwin & mingw32 builds *DONE* Fix the 'distcheck' rule Update 'dist' rule to remove junk from visual studio builds. *DONE* 12-31-2000: Go outside sometime :) *DONE* perhaps create some VC templates and autoconf tempalates for new projects using this package *DONE* 6-20-2000: Project configuration: create a include/ directory off project root and move all the headers that clients should use there - keep the system dependant headers & all sources in the src/ directory ZThread-2.3.2/aclocal.m40000644000175000001440000100110510215006207011623 00000000000000# generated automatically by aclocal 1.7.9 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002 # Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. # Do all the work for Automake. -*- Autoconf -*- # This macro actually does too much some checks are only needed if # your package does certain things.

I can only actively maintain one method for compiling and configuring the source. ./configure --help will provide a list of options detailing this method. * Any other method is up to you. There are simply too many compilers, too many versions and too many platforms to maintain separate build files for. BUT, this doesn't mean you are out of luck. I have structured the code so that it is very simple to compile the library however suits your needs best. All you need to do is include the .cxx files in the src/ directory (not the subdirectories) in your build rule, and add the include directory to your compilers include/ path. Anything else you need to do is specific to your compiler and I leave the details up to you. Anything you want to tweak configuration-wise can be done by editing include/zthread/Config.h ZThread-2.3.2/LICENSE0000644000175000001440000000204110214715064010776 00000000000000Copyright (c) 2005, Eric Crahen Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Since version 2.2.11, the ZThreads library has undergone some revisions. Part of that was a thorough updating of the documentation.

Browse the doxygen-generated documentation online:

Some of the older documents on the site with regard to porting the library, or the structure of things were rendered obsolete and so they were removed. If you are interested in porting the library to another platform, please contact the author directly.

If any updates to the documentation need to be made for this release, they will appear here and in the CVS.

Examples

* - Launching a task * - Waiting for a task * - Sharing a task * *

Launching a task

* * A thread is started simply by constructing a thread object and giving * it a task to perform. The thread will continue to run its task, even * after the Thread object used to launch the thread has gone out of scope. * * @code * #include "zthread/Thread.h" * #include * * using namespace ZThread; * * class aRunnable : public Runnable { * * void run() { * * Thread::sleep(1000); * std::cout << "Hello from another thread" << std::endl; * * } * * }; * * int main() { * * try { * * // Implictly constructs a Task * Thread t(new aRunnable); * * } catch(Synchronization_Exception& e) { * std::cerr << e.what() << std::endl; * } * * std::cout << "Hello from the main thread" << std::endl; * * // Output: * * // Hello from the main thread * // Hello from another thread * * return 0; * * } * * @endcode * *

Waiting for a task

* * A user can exercise some simple synchronization by waiting for a thread * to complete running its task. * * @code * #include "zthread/Thread.h" * #include * * using namespace ZThread; * * class aRunnable : public Runnable { * public: * * void run() { * * Thread::sleep(1000); * std::cout << "Hello from another thread" << std::endl; * * } * * }; * * int main() { * * try { * * // Implictly constructs a Task * Thread t(new aRunnable); * t.wait(); * * } catch(Synchronization_Exception& e) { * std::cerr << e.what() << std::endl; * } * * std::cout << "Hello from the main thread" << std::endl; * * // Output: * * // Hello from another thread * // Hello from the main thread * * return 0; * * } * * @endcode * *

Sharing a task

* * The same task can be shared by more than one thread. A Task is constructed * from a Runnable, and that Task object is copied by value and handed off to * each thread. * * @code * #include "zthread/Thread.h" * #include * * using namespace ZThread; * * class aRunnable : public Runnable { * * void run() { * * Thread::sleep(1000); * std::cout << "Hello from another thread" << std::endl; * * } * * }; * * int main() { * * try { * * // Explictly constructs a Task * Task task(new aRunnable); * * // Two threads created to run the same Task * Thread t1(task); * Thread t2(task); * * } catch(Synchronization_Exception& e) { * std::cerr << e.what() << std::endl; * } * * std::cout << "Hello from the main thread" << std::endl; * * // Output: * * // Hello from the main thread * // Hello from another thread * // Hello from another thread * * return 0; * * } * * @endcode */ class ZTHREAD_API Thread : public Cancelable, public Waitable, public NonCopyable { //!

Examples

* * - Default initial value * - User-specified initial value * - User-specified inherited value * *

Default initial value

* A ThreadLocal that does not inherit, and uses the default value * for an int as its initial value. * * @code * * #include "zthread/ThreadLocal.h" * #include "zthread/Thread.h" * #include * * using namespace ZThread; * * class aRunnable : public Runnable { * ThreadLocal localValue; * public: * void run() { * std::cout << localValue.get() << std::endl; * } * }; * * int main() { * * // Create a shared task to display ThreadLocal values * Task task(new aRunnable); * * Thread t0(task); t0.wait(); * Thread t1(task); t1.wait(); * Thread t2(task); t2.wait(); * * // Output: * * // 0 * // 0 * // 0 * * return 0; * * } * * @endcode * *

User-specified initial value

* A ThreadLocal that does not inherit, and uses a custom initial value. * * @code * * #include "zthread/ThreadLocal.h" * #include "zthread/Thread.h" * #include * * using namespace ZThread; * * struct anInitialValueFn { * int operator()() { * static int next = 100; * int val = next; next += 100; * return val; * } * }; * * class aRunnable : public Runnable { * ThreadLocal localValue; * public: * void run() { * std::cout << localValue.get() << std::endl; * } * }; * * int main() { * * // Create a shared task to display ThreadLocal values * Task task(new aRunnable); * * Thread t0(task); t0.wait(); * Thread t1(task); t1.wait(); * Thread t2(task); t2.wait(); * * // Output: * * // 100 * // 200 * // 300 * * return 0; * * } * * @endcode * *

User-specified inherited value
