+
+The OMNI thread abstraction is designed to provide a common set of
+thread operations for use in programs written in C++. Programs
+written using the abstraction should be much easier to port between
+different architectures with different underlying threads primitives.<BR>
+<BR>
+The programming interface is designed to be similar to the C language
+interface to POSIX threads (IEEE draft standard 1003.1c --- previously
+1003.4a, often known as ``pthreads'' [<A HREF="#pthreads"><CITE>POSIX94</CITE></A>]).<BR>
+<BR>
+Much of the abstraction consists of simple C++ object wrappers around
+pthread calls. However for some features such as thread-specific
+data, a better interface can be offered because of the use of C++.<BR>
+<BR>
+Some of the more complex features of pthreads are not supported
+because of the difficulty of ensuring the same features can be offered
+on top of other thread systems. Such features include thread
+cancellation and complex scheduling control (though simple thread
+priorities are supported).<BR>
+<BR>
+The abstraction layer is currently implemented for the following
+architectures / thread systems:
+<UL><LI>Solaris 2.x using pthreads draft 10
+<LI>Solaris 2.x using solaris threads (but pthreads version is now standard)
+<LI>Alpha OSF1 using pthreads draft 4
+<LI>Windows NT using NT threads
+<LI>Linux 2.x using Linuxthread 0.5 (which is based on pthreads draft 10)
+<LI>Linux 2.x using MIT pthreads (which is based on draft 8)
+<LI>ATMos using pthreads draft 6 (but not Virata ATMos)</UL>
+See the <TT>omnithread.h</TT> header file for full details of the API.
+The descriptions below assume you have some previous knowledge of
+threads, mutexes, condition variables and semaphores. Also refer to
+other documentation ([<A HREF="#birrell"><CITE>Birrell89</CITE></A>], [<A HREF="#pthreads"><CITE>POSIX94</CITE></A>]) for further
+explanation of these ideas (particularly condition variables, the use
+of which may not be particularly intuitive when first encountered).<BR>
+<BR>
+<!--TOC section Synchronisation objects-->
+
+<H2><A NAME="htoc2">2</A>&nbsp;&nbsp;Synchronisation objects</H2><!--SEC END -->
+
+Synchronisation objects are used to synchronise threads within the
+same process. There is no inter-process synchronisation provided.
+The synchronisation objects provided are mutexes, condition variables
+and counting semaphores.<BR>
+<BR>
+<!--TOC subsection Mutex-->
+
+<H3><A NAME="htoc3">2.1</A>&nbsp;&nbsp;Mutex</H3><!--SEC END -->
+
+An object of type <TT>omni_mutex</TT> is used for mutual exclusion.
+It provides two operations, <TT>lock()</TT> and <TT>unlock()</TT>.
+The alternative names <TT>acquire()</TT> and <TT>release()</TT> can be
+used if preferred. Behaviour is undefined when a thread attempts to
+lock the same mutex again or when a mutex is locked by one thread and
+unlocked by a different thread.<BR>
+<BR>
+<!--TOC subsection Condition Variable-->
+
+<H3><A NAME="htoc4">2.2</A>&nbsp;&nbsp;Condition Variable</H3><!--SEC END -->
+
+A condition variable is represented by an <TT>omni_condition</TT> and
+is used for signalling between threads. A call to <TT>wait()</TT>
+causes a thread to wait on the condition variable. A call to
+<TT>signal()</TT> wakes up at least one thread if any are waiting. A
+call to <TT>broadcast()</TT> wakes up all threads waiting on the
+condition variable.<BR>
+<BR>
+When constructed, a pointer to an <TT>omni_mutex</TT> must be given.
+A condition variable <TT>wait()</TT> has an implicit mutex
+<TT>unlock()</TT> and <TT>lock()</TT> around it. The link between
+condition variable and mutex lasts for the lifetime of the condition
+variable (unlike pthreads where the link is only for the duration of
+the wait). The same mutex may be used with several condition
+variables.<BR>
+<BR>
+A wait with a timeout can be achieved by calling
+<TT>timed_wait()</TT>. This is given an absolute time to wait until.
+The routine <TT>omni_thread::get_time()</TT> can be used to turn a
+relative time into an absolute time. <TT>timed_wait()</TT> returns
+<TT>true</TT> if the condition was signalled, <TT>false</TT> if the
+time expired before the condition variable was signalled.<BR>
+<BR>
+<!--TOC subsection Counting semaphores-->
+
+<H3><A NAME="htoc5">2.3</A>&nbsp;&nbsp;Counting semaphores</H3><!--SEC END -->
+
+An <TT>omni_semaphore</TT> is a counting semaphore. When created it
+is given an initial unsigned integer value. When <TT>wait()</TT> is
+called, the value is decremented if non-zero. If the value is zero
+then the thread blocks instead. When <TT>post()</TT> is called, if
+any threads are blocked in <TT>wait()</TT>, exactly one thread is
+woken. If no threads were blocked then the value of the semaphore is
+incremented.<BR>
+<BR>
+If a thread calls <TT>try_wait()</TT>, then the thread won't block if
+the semaphore's value is 0, returning <TT>false</TT> instead.<BR>
+<BR>
+There is no way of querying the value of the semaphore.<BR>
+<BR>
+<!--TOC section Thread object-->
+
+<H2><A NAME="htoc6">3</A>&nbsp;&nbsp;Thread object</H2><!--SEC END -->
+
+A thread is represented by an <TT>omni_thread</TT> object. There are
+broadly two different ways in which it can be used.<BR>
+<BR>
+The first way is simply to create an <TT>omni_thread</TT> object,
+giving a particular function which the thread should execute. This is
+like the POSIX (or any other) C language interface.<BR>
+<BR>
+The second method of use is to create a new class which inherits from
+<TT>omni_thread</TT>. In this case the thread will execute the
+<TT>run()</TT> member function of the new class. One advantage of
+this scheme is that thread-specific data can be implemented simply by
+having data members of the new class.<BR>
+<BR>
+When constructed a thread is in the "new" state and has not actually
+started. A call to <TT>start()</TT> causes the thread to begin
+executing. A static member function <TT>create()</TT> is provided to
+construct and start a thread in a single call. A thread exits by
+calling <TT>exit()</TT> or by returning from the thread function.<BR>
+<BR>
+Threads can be either detached or undetached. Detached threads are
+threads for which all state will be lost upon exit. Other threads
+cannot determine when a detached thread will disappear, and therefore
+should not attempt to access the thread object unless some explicit
+synchronisation with the detached thread guarantees that it still
+exists.<BR>
+<BR>
+Undetached threads are threads for which storage is not reclaimed
+until another thread waits for its termination by calling
+<TT>join()</TT>. An exit value can be passed from an undetached
+thread to the thread which joins it.<BR>
+<BR>
+Detached / undetached threads are distinguished on creation by the
+type of function they execute. Undetached threads execute a function
+which has a <TT>void*</TT> return type, whereas detached threads
+execute a function which has a <TT>void</TT> return type.
+Unfortunately C++ member functions are not allowed to be distinguished
+simply by their return type. Thus in the case of a derived class of
+<TT>omni_thread</TT> which needs an undetached thread, the member
+function executed by the thread is called <TT>run_undetached()</TT>
+rather than <TT>run()</TT>, and it is started by calling
+<TT>start_undetached()</TT> instead of <TT>start()</TT>.<BR>
+<BR>
+The abstraction currently supports three priorities of thread, but no
+guarantee is made of how this will affect underlying thread
+scheduling. The three priorities are <TT>PRIORITY_LOW</TT>,
+<TT>PRIORITY_NORMAL</TT> and <TT>PRIORITY_HIGH</TT>. By default all
+threads run at <TT>PRIORITY_NORMAL</TT>. A different priority can be
+specified on thread creation, or while the thread is running using
+<TT>set_priority().</TT> A thread's current priority is returned by
+<TT>priority()</TT>.<BR>
+<BR>
+Other functions provided are <TT>self()</TT> which returns the calling
+thread's <TT>omni_thread</TT> object, <TT>yield()</TT> which
+requests that other threads be allowed to run, <TT>id()</TT> which
+returns an integer id for the thread for use in debugging,
+<TT>state()</TT>, <TT>sleep()</TT> and <TT>get_time()</TT>.<BR>
+<BR>
+<!--TOC section Per-thread data-->
+
+<H2><A NAME="htoc7">4</A>&nbsp;&nbsp;Per-thread data</H2><!--SEC END -->
+
+omnithread supports per-thread data, via member functions of the
+<TT>omni_thread</TT> object.<BR>
+<BR>
+First, you must allocate a key for with the
+<TT>omni_thread::allocate_key()</TT> function. Then, any object
+whose class is derived from <TT>omni_thread::value_t</TT> can be
+stored using the <TT>set_value()</TT> function. Values are retrieved
+or removed with <TT>get_value()</TT> and <TT>remove_value()</TT>
+respectively.<BR>
+<BR>
+When the thread exits, all per-thread data is deleted (hence the base
+class with virtual destructor).<BR>
+<BR>
+Note that the per-thread data functions are <B>not</B> thread safe,
+so although you can access one thread's storage from another thread,
+there is no concurrency control. Unless you really know what you are
+doing, it is best to only access per-thread data from the thread it is
+attached to.<BR>
+<BR>

+
+Obviously you need to include the <TT>omnithread.h</TT> header file in
+your source code, and link in the omnithread library with your
+executable. Because there is a single <TT>omnithread.h</TT> for all
+platforms, certain preprocessor defines must be given as compiler

+<H2><A NAME="htoc9">6</A>&nbsp;&nbsp;Threaded I/O shutdown for Unix</H2><!--SEC END -->
+
+or, how one thread should tell another thread to shut down when it
+might be doing a blocking call on a socket.<BR>
+<BR>
+<B>If you are using omniORB, you don't need to worry about all
+this, since omniORB does it for you.</B> This section is only relevant
+if you are using omnithread in your own socket-based programming. It
+is also seriously out of date.<BR>
+<BR>
+Unfortunately there doesn't seem to be a standard way of doing this
+which works across all Unix systems. I have investigated the
+behaviour of Solaris 2.5 and Digital Unix 3.2. On Digital Unix
+everything is fine, as the obvious method using shutdown() seems to
+work OK. Unfortunately on Solaris shutdown can only be used on a
+connected socket, so we need devious means to get around this
+limitation. The details are summarised below:<BR>
+<BR>
+<!--TOC subsection read()-->
+
+<H3><A NAME="htoc10">6.1</A>&nbsp;&nbsp;read()</H3><!--SEC END -->
+
+Thread A is in a loop, doing <CODE>read(sock)</CODE>, processing the data,
+then going back into the read.<BR>
+<BR>
+Thread B comes along and wants to shut it down --- it can't cancel
+thread A since (i) working out how to clean up according to where A is
+in its loop is a nightmare, and (ii) this isn't available in
+omnithread anyway.<BR>
+<BR>
+On Solaris 2.5 and Digital Unix 3.2 the following strategy works:<BR>
+<BR>
+Thread B does <CODE>shutdown(sock,2)</CODE>.<BR>
+<BR>
+At this point thread A is either blocked inside <CODE>read(sock)</CODE>, or
+is elsewhere in the loop. If the former then read will return 0,
+indicating that the socket is closed. If the latter then eventually
+thread A will call <CODE>read(sock)</CODE> and then this will return 0.
+Thread A should <CODE>close(sock)</CODE>, do any other tidying up, and exit.<BR>
+<BR>
+If there is another point in the loop that thread A can block then
+obviously thread B needs to be aware of this and be able to wake it up
+in the appropriate way from that point.<BR>
+<BR>
+<!--TOC subsection accept()-->
+
+<H3><A NAME="htoc11">6.2</A>&nbsp;&nbsp;accept()</H3><!--SEC END -->
+
+Again thread A is in a loop, this time doing an accept on listenSock,
+dealing with a new connection and going back into accept. Thread B
+wants to cancel it.<BR>
+<BR>
+On Digital Unix 3.2 the strategy is identical to that for read:<BR>
+<BR>
+Thread B does <CODE>shutdown(listenSock,2)</CODE>. Wherever thread A is in
+the loop, eventually it will return <CODE>ECONNABORTED</CODE> from the
+accept call. It should <CODE>close(listenSock)</CODE>, tidy up as necessary
+and exit.<BR>
+<BR>
+On Solaris 2.5 thread B can't do <CODE>shutdown(listenSock,2)</CODE> ---
+this returns <CODE>ENOTCONN</CODE>. Instead the following strategy can be
+used:<BR>
+<BR>
+First thread B sets some sort of "shutdown flag" associated with
+listenSock. Then it does <CODE>getsockaddr(listenSock)</CODE> to find out
+which port listenSock is on (or knows already), sets up a socket
+dummySock, does <CODE>connect(dummySock,</CODE> <CODE>this host, port)</CODE> and
+finally does <CODE>close(dummySock)</CODE>.<BR>
+<BR>
+Wherever thread A is in the loop, eventually it will call
+<CODE>accept(listenSock)</CODE>. This will return successfully with a new
+socket, say connSock. Thread A then checks to see if the "shutdown
+flag" is set. If not, then it's a normal connection. If it is set,
+then thread A closes listenSock and connSock, tidies up and exits.<BR>
+<BR>
+<!--TOC subsection write()-->
+
+<H3><A NAME="htoc12">6.3</A>&nbsp;&nbsp;write()</H3><!--SEC END -->
+
+Thread A may be blocked in write, or about to go in to a
+potentially-blocking write. Thread B wants to shut it down.<BR>
+<BR>
+On Solaris 2.5:<BR>
+<BR>
+Thread B does <CODE>shutdown(sock,2)</CODE>.<BR>
+<BR>
+If thread A is already in <CODE>write(sock)</CODE> then it will return with
+<CODE>ENXIO</CODE>. If thread A calls write after thread B calls shutdown
+this will return <CODE>EIO</CODE>.<BR>
+<BR>
+On Digital Unix 3.2:<BR>
+<BR>
+Thread B does <CODE>shutdown(sock,2)</CODE>.<BR>
+<BR>
+If thread A is already in <CODE>write(sock)</CODE> then it will return the
+number of bytes written before it became blocked. A subsequent call
+to write will then generate <CODE>SIGPIPE</CODE> (or <CODE>EPIPE</CODE> will be
+returned if <CODE>SIGPIPE</CODE> is ignored by the thread).<BR>
+<BR>
+<!--TOC subsection connect()-->
+
+<H3><A NAME="htoc13">6.4</A>&nbsp;&nbsp;connect()</H3><!--SEC END -->
+
+Thread A may be blocked in connect, or about to go in to a
+potentially-blocking connect. Thread B wants to shut it down.<BR>
+<BR>
+On Digital Unix 3.2:<BR>
+<BR>
+Thread B does <CODE>shutdown(sock,2)</CODE>.<BR>
+<BR>
+If thread A is already in <CODE>connect(sock)</CODE> then it will return a
+successful connection. Subsequent reading or writing will show that
+the socket has been shut down (i.e. read returns 0, write generates
+<CODE>SIGPIPE</CODE> or returns <CODE>EPIPE</CODE>). If thread A calls connect
+after thread B calls shutdown this will return <CODE>EINVAL</CODE>.<BR>
+<BR>
+On Solaris 2.5:<BR>
+<BR>
+There is no way to wake up a thread which is blocked in connect.
+Instead Solaris forces us through a ridiculous procedure whichever way
+we try it. One way is this:<BR>
+<BR>
+First thread A creates a pipe in addition to the socket. Instead of
+shutting down the socket, thread B simply writes a byte to the pipe.<BR>
+<BR>
+Thread A meanwhile sets the socket to non-blocking mode using
+<CODE>fcntl(sock,</CODE> <CODE>F_SETFL, O_NONBLOCK)</CODE>. Then it calls connect
+on the socket --- this will return <CODE>EINPROGRESS</CODE>. Then it must
+call <CODE>select()</CODE>, waiting for either sock to become writable or
+for the pipe to become readable. If select returns that just sock is
+writable then the connection has succeeded. It then needs to set the
+socket back to blocking mode using <CODE>fcntl(sock, F_SETFL, 0)</CODE>. If
+instead select returns that the pipe is readable, thread A closes the
+socket, tidies up and exits.<BR>
+<BR>
+An alternative method is similar but to use polling instead of the
+pipe. Thread B justs sets a flag and thread A calls select with a
+timeout, periodically waking up to see if the flag has been set.<BR>

+% 
+% Idea is to have all the characters normally included in Type 1 fonts
+% available for typesetting. This is effectively the characters in Adobe
+% Standard Encoding + ISO Latin 1 + extra characters from Lucida.
+% 
+% Character code assignments were made as follows:
+% 
+% (1) the Windows ANSI characters are almost all in their Windows ANSI
+% positions, because some Windows users cannot easily reencode the
+% fonts, and it makes no difference on other systems. The only Windows
+% ANSI characters not available are those that make no sense for
+% typesetting -- rubout (127 decimal), nobreakspace (160), softhyphen
+% (173). quotesingle and grave are moved just because it's such an
+% irritation not having them in TeX positions.
+% 
+% (2) Remaining characters are assigned arbitrarily to the lower part
+% of the range, avoiding 0, 10 and 13 in case we meet dumb software.
+% 
+% (3) Y&Y Lucida Bright includes some extra text characters; in the
+% hopes that other PostScript fonts, perhaps created for public
+% consumption, will include them, they are included starting at 0x12.
+% 
+% (4) Remaining positions left undefined are for use in (hopefully)
+% upward-compatible revisions, if someday more characters are generally
+% available.
+% 
+% (5) hyphen appears twice for compatibility with both 
+% ASCII and Windows.

+# Generating Python docstrings from C++ code using doxygen
+#
+
+There are at least two strategies for this:
+  - use xsltproc as described below
+  - use doxy2swig.py (included in this directory)
+
+FIXME: get one of these working (probably doxy2swig since it doesn't
+add any additional dependencies).
+
+----------------------------------------------------------------
+
+Note: Robin's patch is in SWIG >= 1.3.23
+
+--------------------------------------------------------------------------------
+From: http://mailman.cs.uchicago.edu/pipermail/swig/2004-October/010604.html
+
+> I applied the docstring patch. '%feature("autodoc",1");' is working as 
+> expected ...
+
+[problem solved. ...]
+
+> I can not agree more with the doxygen idea. I am using doxygen for 
+> documentation and I have been trying to put doxygen output to the 
+> python interface. Automatic generation of %feature("docstring") lines 
+> from doxygen output is the closest solution I can think of but the 
+> workload is still pretty big. How I wish this feature can be 
+> implemented in the near future.
+
+I have successfully extracted function/class description from doxygen 
+generated xml files, using an xslt script. To add doxygen generated 
+description to each class/function, you will need to (tested under 
+linux, note that this works only for Python, using Robin's docstring 
+patch)
+
+1. download swig source, apply Robin's docstring patch from
+   https://sourceforge.net/tracker/index.php?func=detail&aid=1023309&group_id=1645&atid=301645
+   compile and install
+
+2. generate doxygen document with option "GENERATE_XML = YES"
+
+3. copy the attached script (save as swig.xsl) to the doc/xml directory 
+   and run
+
+     > xsltproc swig.xsl index.xml > temp_doc.i
+     > cat temp_doc.i | sed 's/"/\\"/g' | sed 's/__QuOtE__/"/g' > swig_doc.i
+
+   you will get an interface file with lines like
+     %feature("docstring") class "class description";
+     %feature("docstring") class::function "member function 
+         description";
+
+   the second step is necessary since there might be " in descriptions 
+   and I need to backquote them before I replace __QuOtE__ by real 
+   quotes. (xslt experts may know how to post-process <xsl:value-of> and 
+   make the script easier to use.)
+
+4. in your interface file, add
+     %include "siwg_doc.i"
+     %feature("autodoc","1") ;
+
+Hope this helps.
