-Notes on the OpenBSD threaded C library  (-lc_r)
-================================================
-
-Sources
-
-  The main bulk of this library came from:
-   . FreeBSD's libc_r (John Birrell)
-     - The scheduler and locking code in the uthread directory.
-     - Some of the manual pages in the man directory.
-     - <pthreads.h>
-   . MIT pthreads (Chris Provenzano)
-     - The test code in the regress/lib/libc_r directory
-
-  I'm mainly tracking changes in FreeBSD's libc_r and integrating
-  them as I can. The major changes are outlined at the end of this
-  file.
-
-Standards
-
-  This implementation has also been mindful of:
-   . Posix Threads[1]
-   . Single Unix Specification[2]
-
-Conformance
-
-  Only the absolutely required re-entrant functions have been added
-  to the C library interface headers (in /usr/src/include).
-
-  The conformance goals used were: minimal implementation; strict
-  conformance with standard; provide reasonable utility when standards
-  are spineless (e.g., our asynchronous cancel is eager even though
-  POSIX says async cancels may be acted upon at any time -- ie
-  never.)
-
-  The widely used, but non-standard, gethostbyname_r() has been
-  half-heartily added (but not prototyped in a header - see source
-  for details).  Please contact me if you have pointers to
-  standards/comments about this function.
-
-  Re-entrant functions added for the standards have also been made 
-  available to libc (i.e. without the need to define _POSIX_THREADS).
-
-Change strategy in libc
-
-  The approach taken in making the libc functions re-entrant was to
-  develop some macros that handle:
-	. file locking
-	. monitors (thread-shared data structure locking)
-	. per-thread private data structure allocation
-
-  These macros were used to avoid copious amounts of #ifdef
-  statements[3].
-
-  In the non-threaded libc, file locking and the monitors are no-ops;
-  the per-thread private data structures were previously declared
-  static and the macros maintain this.
-
-  In the threaded libc_r, file locking is as per the FreeBSD file
-  descriptor locking, and the monitors are pthread_mutex operations.
-  Per-thread private data structures use the pthread_specific
-  functions to dynamically allocate memory on their first use,
-  initialising them from the static (and hidden) per-compilation-unit
-  data structures.  In this way, each thread appears to have its
-  very own private libc state.
-
-Errno
-
-  Unlike the FreeBSD and MIT pthreads package, errno is not a macro
-  like __error(); instead it is part of the per-thread context:
-  saved and restored like a register. This has several advantages
-  over the errno-as-a-macro method:
-
-    - The syscall/cerror code does not have to be re-written
-    - Libraries compiled without thread support will still work
-    - Easier to port old packages that use errno, but don't include
-      <errno.h> to get the macro
-    - No need to go through all sources and find where errno is
-      used as a field name or formal parameter name.
-
-  The overhead of saving and restoring an integer was considered
-  too tiny to worry about in comparison to the huge penalty hit of
-  handling a signal and restoring the rest of a thread's context.
-
-  It has been pointed out that this technique will not work in a
-  mutiprocessor environment, and this is quite true. However the
-  following reasons are quite persuasive:
-
-    - OpenBSD does not do MP (yet)
-    - This (FreeBSD uthread) implementation will not work in an MP
-      environment anyway because _thread_run is not a cpu-local
-      variable.
-    - There is a lot of coupling between binary ports, the 'old'
-      libc and other standard libraries. It is predicted that it
-      will be a huge headache to come up with a scheme that when
-      someone tries to upgrade, everything won't break in a spectacular
-      fashion, leaving bits of crippled ports, executables and
-      shattered libraries everywhere.
-
-Compiler support
-
-  The in-tree gcc had its config/openbsd.h modified to support a
-  `-pthread' switch. Using this switch defines _POSIX_THREADS for
-  cpp, and replaces the normal -lc linker option with -lc_r.
-
-  The objective-C component was also made aware of posix threads,
-  via the configure switch --enable-threads=posix. {This has not
-  been well tested though.}
-
-Debugger support
-
-  The in-tree gdb has been augmented to recognise when a executable
-  linked with -lc_r is being debugged. All the documented gdb threads
-  commands will then work. (Except you can't resume/step execution
-  in a thread other than the 'current' one.)
-
-  To get detailed state information, issue:
-
-	(gdb) call _thread_dump_info()
-
-  This will show what mutexes, condvars or file locks each process
-  is waiting on. If you use _flockfile_debug() instead of flockfile()
-  in your programs, source code references will appear in here too.
-  (see <stdio.h>)
-
-Changes to FreeBSD uthreads
-
-  Although this implementation tracks the FreeBSD libc_r tree to
-  a large extent, the following significant changes have been made 
-  to John Birrell's uthreads implementation that have yet to appear
-  (or may never appear) in FreeBSD's implementation:
-
-    - architecture independent code generalised and moved out of
-      #ifdef's[3] (now support for sparc, mips, m68k, powerpc added
-      to i386, alpha)
-    - the SIGINFO handler generates much more friendly/useful output
-    - an implementation of poll() {probably bogus, but X11 seems to
-      work}
-    - an implementation of pthread_cancel()
-    - an implementation of pthread_[gs]etscope() {bogus}
-    - removal of the freebsd's support for init(8) {i.e., pid == 1}
-
-Caveats
-
-  This library is not 100% standards compliant - yet. It is certainly
-  moving in that direction though. There are still some unresolved
-  isseues, and the interested reader is directed towards the TODO
-  file.

-
-This is a list of things that still need to be done:
-
-* fix the signal handling re-entrancy bug that FreeBSD have left in :(
-
-* wrap vfork (basically the same as fork())
-
-* wrap itimer() syscalls so that the _ITIMER_SCHED_TIMER can't be trashed
-
-* Move the md include stuff so that it appears in /usr/include/<arch>/
-  That way, gdb's thread stuff can be built sanely and maybe other
-  uthread-aware stuff can make use of it?
-
-* Move to using -lpthread. Needs weak symbol support in all as and ld.so
-  implementations.
-  [espie@ looking at unifying toolchain]
-  [weak symbols put into libc. libpthread built. everything works on i386]
-
-* Add 
-      pthread_condattr_[gs]etpshared()	-- and add warn_references
-      pthread_mutexattr_[gs]etpshared()
-      sched_setparam()
-      sched_setscheduler()
-
-* Add _warn_references to the schedprio stuff
-
-* shouldn't pthread_yield() be marked depreciated?
-  [it is draft 4.]
-
-* Add thread stuff to the other archs in libc/arch/; ie change
-  some usages of ENTRY to SYSENTRY in some .S files and add
-  the new macros to their SYS.h. 
-  [wip]
-
-* Test that thread_init is automatically called on every arch, regardless
-  of whether the exe is statically linked or not.
-  [problems with new egcs?]
-
-* Add UNIX98's pthread_attr_[sg]etguardsize(). This would probably be
-  straightforward.
-
-* Keep a handle on how netbsd are going with their kernel threads
-  [argument is that openbsd is not multi-processor, so user threads will
-   retain stability and still give reasonable performance. talked to mwp@]
-
-* Look into how asynchronous I/O can help us. In particular, the
-  (unimplemented) aio*() functions.
-  [doesn't help very much for 1003.1c.]
-
-* Update the libc manual pages to describe the posix re-entrant functions.
-  Although this is actually trivial to do, I have to decide on a
-  consistent way of adding them - maybe `.Sh THREAD-SAFE FUNCTIONS' ?
-  Should look into standards to see what they suggest/did..
-  May also need to document "This is not thread-safe" for some library
-  functions (yet to be identified).
-  [Need to ask aaron@ for his opinion.]
-
-* Find out where freebsd/netbsd use pread() and pwrite().. i think
-  its in the database routines mostly.
-
-* Figure out what to do with the configuration system variables (_SC_*)
-  that are defined by POSIX 1003.1c (at least update sysconf(3))
-
-* Compare with PTL (http://www.media.osaka-cu.ac.jp/~k-abe/PTL/)
-  [snarfed some sparc md stuff]
-
-* Verify that threads work with:
-	- perl (in-tree) [almost]
-	- objc (in-tree gcc)
-	- ssl (in-tree) [triv]
-	- gdb
-	- ports
-		- audio/xmms
-		- bechmarks/iozone
-		- databases/mysql
-		- devel/glib [yes]
-		- devel/sdl [yes]
-		- graphics/ggi
-		- graphics/gii

-* Fix ufs_select and nfs_select in the kernel to give REAL answers. [ha!]
-
-* Clean up the way that signals are delivered to threads. Yuk.
-
-* Make getaddrinfo(3) thread-safe.
-
-* What to do with gethostby*_r(3)?
-
-* Look into getpw*_r(3).

-.Dt FLOCKFILE 3
-.Os
-.Sh NAME
-.Nm flockfile ,
-.Nm ftrylockfile ,
-.Nm funlockfile
-.Nd application level locking of stdio files
-.Sh SYNOPSIS
-.Fd #include <stdio.h>
-.Ft void
-.Fn flockfile "FILE *file"
-.Ft int
-.Fn ftrylockfile "FILE *file"
-.Ft void
-.Fn funlockfile "FILE *file"
-.Sh DESCRIPTION
-The
-.Fn flockfile ,
-.Fn ftrylockfile ,
-and
-.Fn funlockfile
-functions provide for explicit application-level locking of stdio
-.Ft "FILE *"
-objects.
-These functions can be used by a thread to delineate a sequence
-of I/O statements that are to be executed as a unit.
-.Pp
-The
-.Fn flockfile
-function is used by a thread to acquire ownership of a
-.Ft "FILE *"
-object.
-.Pp
-The
-.Fn ftrylockfile
-function is used by a thread to acquire ownership of a
-.Ft "FILE *"
-object if the object is available;
-.Fn ftrylockfile
-is a non-blocking version of
-.Fn flockfile .
-.Pp
-The
-.Fn funlockfile
-function is used to relinquish the ownership granted to the thread.
-The behaviour is undefined if a thread other than the current owner calls the
-.Fn funlockfile
-function.
-.Pp
-Logically, there is a lock count associated with each
-.Ft "FILE *"
-object.
-This count is implicitly intialized to zero when the
-.Ft "FILE *"
-object is created.
-The
-.Ft "FILE *"
-object is unlocked when the count is zero.
-When the count is positive, a single thread owns the
-.Ft "FILE *"
-object.
-When the
-.Fn flockfile
-function is called, if the count is zero or if the count is positive and
-the caller owns the
-.Ft "FILE *"
-object, the count is incremented.
-Otherwise, the calling thread is suspended, waiting for the count to
-return to zero.
-Each call to
-.Fn funlockfile
-decrements the count.
-This allows matching calls to
-.Fn flockfile
-(or successful calls to
-.Fn ftrylockfile )
-and
-.Fn funlockfile
-to be nested.
-.Pp
-Library functions that reference
-.Ft "FILE *"
-behave as if they use
-.Fn flockfile
-and
-.Fn funlockfile
-internally to obtain ownership of these
-.Ft "FILE *"
-objects.
-.Sh RETURN VALUES
-None for
-.Fn flockfile
-and
-.Fn funlockfile .
-The function
-.Fn ftrylock
-returns zero for success and non-zero to indicate that the lock cannot
-be acquired.
-.Sh ERRORS
-None.

-.Sh DESCRIPTION
-The

-be cancelled.
-The target thread's cancelability state and type determines
-when the cancellation takes effect.
-When the cancellation is acted on, the cancellation cleanup handlers for

-When the last cancellation cleanup handler returns,
-the thread-specific data destructor functions will be called for
-.Fa thread .
-When the last destructor function returns,

-will be terminated.
-.Pp
-The cancellation processing in the target thread runs asynchronously with
-respect to the calling thread returning from
-.Fn pthread_cancel .
-.Pp
-A status of
-.Dv PTHREAD_CANCELED
-is made available to any threads joining with the target.
-The symbolic constant
-.Dv PTHREAD_CANCELED
-expands to a constant expression of type
-.Ft "(void *)"
-whose value matches no pointer to an object in memory nor the value
-.Dv NULL .

-.Ft void
-.Fn pthread_exit "void *value_ptr"
-.Sh DESCRIPTION
-The
-.Fn pthread_exit
-function terminates the calling thread and makes the value
-.Fa value_ptr
-available to any successful join with the terminating thread.
-Any
-cancellation cleanup handlers that have been pushed and are not yet popped
-are popped in the reverse order that they were pushed and then executed.
-After all cancellation handlers have been executed, if the thread has any
-thread-specific data, appropriate destructor functions are called in an
-unspecified order.
-Thread termination does not release any application
-visible process resources, including, but not limited to, mutexes and
-file descriptors, nor does it perform any process level cleanup
-actions, including, but not limited to, calling
-.Fn atexit
-routines that may exist.
-.Pp
-An implicit call to
-.Fn pthread_exit
-is made when a thread other than the thread in which
-.Fn main
-was first invoked returns from the start routine that was used to create
-it. The function's return value serves as the thread's exit status.
-.Pp
-The behavior of
-.Fn pthread_exit
-is undefined if called from a cancellation handler or destructor function
-that was invoked as the result of an implicit or explicit call to
-.Fn pthread_exit .
-.Pp
-After a thread has terminated, the result of access to local (auto)
-variables of the thread is undefined.
-Thus, references to local variables
-of the exiting thread should not be used for the
-.Fn pthread_exit
-.Fa value_ptr
-parameter value.
-.Pp
-The process will exit with an exit status of 0 after the last thread has
-been terminated.
-The behavior is as if the implementation called
-.Fn exit
-with a zero argument at thread termination time.
-.Sh RETURN VALUES
-The
-.Fn pthread_exit
-function cannot return to its caller.
-.Sh ERRORS
-None.

-.Sh SYNOPSIS
-.Fd #include <pthread.h>
-.Ft int
-.Fn pthread_key_create "pthread_key_t *key" "void (*destructor)(void *)"
-.Sh DESCRIPTION
-The
-.Fn pthread_key_create
-function creates a thread-specific data key visible to all threads in the
-process.
-Key values provided by
-.Fn pthread_key_create
-are opaque objects used to locate thread-specific data.
-Although the same
-key value may be used by different threads, the values bound to the key
-by
-.Fn pthread_setspecific
-are maintained on a per-thread basis and persist for the life of the calling
-thread.
-.Pp
-Upon key creation, the value NULL is associated with the new key in all
-active threads.
-Upon thread creation, the value NULL is associated with all
-defined keys in the new thread.
-.Pp
-An optional destructor function may be associated with each key value.
-At thread exit, if a key value has a non-NULL destructor pointer, and the
-thread has a non-NULL value associated with the key, the function pointed
-to is called with the current associated value as its sole argument.
-The order of destructor calls is unspecified if more than one destructor exists
-for a thread when it exits.
-.Pp
-If, after all the destructors have been called for all non-NULL values
-with associated destructors, there are still some non-NULL values with
-associated destructors, then the process is repeated.
-If, after at least
-[PTHREAD_DESTRUCTOR_ITERATIONS] iterations of destructor calls for
-outstanding non-NULL values, there are still some non-NULL values with
-associated destructors, the implementation stops calling destructors.
-.Sh RETURN VALUES
-If successful, the
-.Fn pthread_key_create
-function will store the newly created key value at the location specified by
-.Fa key
-and returns zero.
-Otherwise an error number will be returned to indicate the error.
-.Sh ERRORS
-.Fn pthread_key_create
-will fail if:
-.Bl -tag -width Er
-.It Bq Er EAGAIN
-The system lacked the necessary resources to create another thread-specific

-.Pp
-The
-.Fn pthread_testcancel
-function creates a cancellation point in the calling thread.
-The
-.Fn pthread_testcancel
-function has no effect if cancelability is disabled.
-.Ss Cancelability States
-The cancelability state of a thread determines the action taken upon
-receipt of a cancellation request.
-The thread may control cancellation in a number of ways.
-.Pp
-Each thread maintains its own
-.Dq cancelability state
-which may be encoded in two bits:
-.Bl -hang
-.It Em Cancelability Enable
-When cancelability is
-.Dv PTHREAD_CANCEL_DISABLE ,
-cancellation requests against the target thread are held pending.
-.It Em Cancelability Type
-When cancelability is enabled and the cancelability type is
-.Dv PTHREAD_CANCEL_ASYNCHRONOUS ,
-new or pending cancellation requests may be acted upon at any time.
-When cancelability is enabled and the cancelability type is
-.Dv PTHREAD_CANCEL_DEFERRED ,
-cancellation requests are held pending until a cancellation point (see
-below) is reached.
-If cancelability is disabled, the setting of the
-cancelability type has no immediate effect as all cancellation requests
-are held pending; however, once cancelability is enabled again the new
-type will be in effect.
-.El
-.Ss Cancellation Points
-Cancellation points will occur when a thread is executing the following
-functions:
-.Fn close ,
-.Fn creat ,
-.Fn fcntl ,
-.Fn fsync ,
-.Fn msync ,
-.Fn nanosleep ,
-.Fn open ,
-.Fn pause ,
-.Fn pthread_cond_timedwait ,
-.Fn pthread_cond_wait ,

-.Fn pthread_testcancel ,
-.Fn read ,
-.Fn sigwaitinfo ,
-.Fn sigsuspend ,
-.Fn sigwait ,
-.Fn sleep ,
-.Fn system ,
-.Fn tcdrain ,
-.Fn wait ,
-.Fn waitpid ,
-.Fn write .
-.Sh RETURN VALUES
-If successful, the
-.Fn pthread_setcancelstate
-and
-.Fn pthread_setcanceltype
-functions will return zero.
-Otherwise, an error number shall be returned to indicate the error.
-.Pp
-The
-.Fn pthread_setcancelstate
-and
-.Fn pthread_setcanceltype
-functions are used to control the points at which a thread may be
-asynchronously cancelled.
-For cancellation control to be usable in modular
-fashion, some rules must be followed.
-.Pp
-For purposes of this discussion, consider an object to be a generalization
-of a procedure. It is a set of procedures and global variables written as
-a unit and called by clients not known by the object.
-Objects may depend on other objects.
-.Pp
-First, cancelability should only be disabled on entry to an object, never
-explicitly enabled.
-On exit from an object, the cancelability state should
-always be restored to its value on entry to the object.
-.Pp
-This follows from a modularity argument: if the client of an object (or the
-client of an object that uses that object) has disabled cancelability, it is
-because the client doesn't want to have to worry about how to clean up if the
-thread is cancelled while executing some sequence of actions.
-If an object
-is called in such a state and it enables cancelability and a cancellation
-request is pending for that thread, then the thread will be cancelled,
-contrary to the wish of the client that disabled.
-.Pp
-Second, the cancelability type may be explicitly set to either
-.Em deferred
-or
-.Em asynchronous
-upon entry to an object.
-But as with the cancelability state, on exit from
-an object that cancelability type should always be restored to its value on
-entry to the object.
-.Pp
-Finally, only functions that are cancel-safe may be called from a thread that
-is asynchronously cancelable.
-.Sh ERRORS
-The function
-.Fn pthread_setcancelstate
-may fail with:
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The specified state is not
-.Dv PTHREAD_CANCEL_ENABLE

-.Sh NAME
-.Nm pthreads
-.Nd POSIX 1003.1c thread interface
-.Sh DESCRIPTION
-A thread is a flow of control within a process.
-Each thread represents a minimal amount of state;
-normally just the cpu state and a signal mask.
-All other process state (such as memory, file descriptors)
-is shared among all of the threads in the process.
-.Pp
-In
-.Ox ,
-threads are implemented in a user-level library.
-A program using these routines must be linked with the
-.Fl pthread
-option.
-.Pp
-The
-.Dv SIGINFO
-signal can be sent to a threaded process to have the library show the state of
-all of its threads.
-The information is sent to the process'
-controlling tty and describes each thread's
-ID,
-state (see
-.Sx Thread states ) ,
-current priority,
-flags (see
-.Sx Thread flags ) ,
-signal mask, and name (as set by
-.Xr pthread_set_name_np 3 ) .
-If the environment variable
-.Ev PTHREAD_DEBUG
-is defined additional information is displayed.
-.Ss Thread states
-Threads can be in one of these states:
-.Bl -tag -offset indent -width Dv -compact
-.It cond_wait
-Executing
-.Xr pthread_cond_wait 3
-or
-.Xr pthread_cond_timedwait 3 .
-.It dead
-Waiting for resource deallocation by the thread garbage collector.
-.It deadlock
-Waiting for a resource held by the thread itself.
-.It fdlr_wait
-File descriptor read lock wait.
-.It fdlw_wait
-File descriptor write lock wait.
-.It fdr_wait
-Executing one of
-.Xr accept 2 ,
-.Xr read 2 ,
-.Xr readv 2 ,
-.Xr recvfrom 2 ,
-.Xr recvmsg 2 .
-.It fdw_wait
-Executing one of
-.Xr connect 2 ,
-.Xr sendmsg 2 ,
-.Xr sendto 2 ,
-.Xr write 2 ,
-.Xr writev 2 .
-.It file_wait
-Executing
-.Xr flockfile 3
-or similar.
-.It join
-Executing
-.Xr pthread_join 3 .
-.It mutex_wait
-Executing
-.Xr pthread_mutex_lock 3 .
-.It poll_wait
-Executing
-.Xr poll 2 .
-.It running
-Scheduled for, or engaged in, program execution.
-.It select_wait
-Executing
-.Xr select 2 .
-.It sigsuspend
-Executing
-.Xr sigsuspend 2 .
-.It sigwait
-Executing
-.Xr sigwait 3 .
-.It sleep_wait
-Executing
-.Xr sleep 3
-or
-.Xr nanosleep 2 .
-.It spinblock
-Waiting for a machine-level atomic lock.
-.It suspended
-Suspended with
-.Xr pthread_suspend_np 3 .
-.It wait_wait
-Executing
-.Xr wait4 2
-or similar.
-.El
-.Ss Thread flags
-The first three flags are one of:
-.Bl -tag -offset indent -width 3en -compact
-.It "p"
-Private, system thread (e.g., the garbage collector).
-.It "E, C, or c"
-Thread is exiting (E), has a cancellation pending (C) (see
-.Xr pthread_cancel 3 ) ,
-or is at a cancellation point (c).
-.It "t"
-Thread is being traced.
-.El
-The next 7 flags refer to thread attributes:
-.Bl -tag -offset indent -width 3en -compact
-.It "C"
-Thread is in the
-.Dv CONDQ .
-.It "R"
-Thread is in the
-.Dv WORKQ .
-.It "W"
-Thread is in the
-.Dv WAITQ .
-.It "P"
-Thread is in the
-.Dv PRIOQ .
-.It "d"
-Thread has been detached (see
-.Xr pthread_detach 3 ) .
-.It "i"
-Thread inherits scheduler properties.
-.It "f"
-Thread will save floating point context.
-.El
-.Ss Scheduling algorithm
-The scheduling algorithm used by the user-level thread library is
-roughly as follows:
-.Bl -enum -compact
-.It
-Threads each have a time slice credit which is debited
-by the actual time the thread spends in running.
-Freshly scheduled threads are given a time slice credit of 100000 usec.
-.It
-Give an incremental priority update to run-enabled threads that
-have not run since the last time that an incremental priority update
-was given to them.
-.It
-Choose the next run-enabled thread with the highest priority,
-that became inactive least recently, and has
-the largest remaining time slice.
-.El
-.Pp
-When all threads are blocked, the process also blocks.
-When there are no threads remaining,
-the process terminates with an exit code of zero.
-.Ss Thread stacks
-Each thread has (or should have) a different stack, whether it be provided by a
-user attribute, or provided automatically by the system.

-.Sh AUTHORS
-John Birrell
-.Pa ( jb@freebsd.org )
-wrote the majority of the user level thread library.
-.\" David Leonard did a fair bit too, but is far too modest.
-.Sh BUGS
-The library contains a scheduler that uses the

-This means that using
-.Xr setitimer 2
-to alter the process virtual timer will have undefined effects.
-The

-will never be delivered to threads in a process.

-Some pthread functions fail to work correctly when linked using the

-option to
-.Xr cc 1
-or
-.Xr gcc 1 .
-The problems do not occur when linked using the
-.Fl ggdb
-option.
