+Nunc Stans Job Safety
+=====================
+
+Nunc Stans 0.2.0 comes with many improvements for job safety. Most consumers of
+this framework will not notice the difference if they are using it
"correctly",
+but in other cases, you may find you have error conditions.
+
+Jobs now flow through a set of states in their lifetime.
+
+States
+------
+
+* WAITING: This represents a job that is idle, and not owned by a worker or event thread.
Any thread can alter this job.
+* NEEDS_DELETE: This represents a job that is marked for deletion. It cannot be accessed
again!
+* DELETED: This represents a job that is deleted. In theory, you can never access a job
in this state.
+* NEEDS_ARM: This is a job that is about to be placed into the event or work queue for
arming, but has not yet been queued.
+* ARMED: This is a job that is currently in the event queue or work queue waiting to be
executed.
+* RUNNING: This is a job that is in the process of executing it's callback right
now.
+
+Diagram
+-------
+
+
+
+WAITING
+-------
+
+All jobs start in the WAITING state. At this point, the job can have two transitions. It
is sent to ns_job_done, and marked as NEEDS_DELETE, or it can be sent to ns_job_rearm, and
marked as NEEDS_ARM. A job that is WAITING can be safely modify with ns_job_set_* and
accessed with ns_job_get_* from any thread.
+
+NEEDS_ARM
+---------
+
+Once a job is in the NEEDS_ARM state, it can not be altered by ns_job_set_*. It can be
read from with ns_job_get_*. It can be sent to ns_job_done (which moves to NEEDS_DELETE),
but generally this is only from within the job callback, with code like the following.
+
+ callback(ns_job_t *job) {
+ ns_job_rearm(job);
+ ns_job_done(job);
+ }
+
+
+NEEDS_ARM in most cases will quickly move to the next state, ARMED
+
+ARMED
+-----
+
+In the ARMED state, this means that the job has been sucessfully queued into the event
*or* work queue. In the ARMED state, the job can be read from with ns_job_get_*, but it
cannot be altered with ns_job_set_*. If a job could be altered while queued, this could
cause issues with the intent of what the job should do (set_data, set_cb, set_done_cb)
etc.
+
+A job that is ARMED and queued can NOT be removed from the queue, or stopped from
running. This is a point of no return!
+
+RUNNING
+-------
+
+In the RUNNING state, the job is in the process of executing the callback that the job
contains. While RUNNING, the thread that is executing the callback may call ns_job_done,
ns_job_rearm, ns_job_get_* and ns_job_set_* upon the job. Note, that calling both
ns_job_done and ns_job_rearm from the callback, as the 'done' is a
'stronger' action we will delete the job even though rearm was also called.
+
+While RUNNING other threads (ie, not the worker thread executing the callback) may only
call ns_job_get_* upon the job. Due to the design of the synchronisation underneath, this
will block until the execution of the callback, so for all intents and purposes by the
time the external thread is able to call ns_job_get_*, the job will have moved to
NEEDS_DELETE, NEEDS_ARM or WAITING.
+
+NEEDS_DELETE
+------------
+
+When you call ns_job_done, this marks the job as NEEDS_DELETE. The deletion actually
occurs at "some later point". When a job is set to NEEDS_DELETE, you may *not*
call any of the ns_job_get_* and ns_job_set_* functions on the job.
+
+DELETED
+-------
+
+This state only exists on the job briefly. This means we are in the process of deleting
the job internally. We execute the ns_job_done_cb at this point, so that the user may
clean up and free any data as required. Only the ns_job_done_cb thread may access the job
at this point.
+
+
+Putting it all together
+-----------------------
+
+This state machine encourages certain types of work flows with jobs. This is because the
current states are opaque to the caller, and are enforced inside of nunc-stans. The most
obviously side effect of a state machine violation is a ASSERT failure with -DDEBUG, or
PR_FAILURE from get()/set(). This encourages certain practices:
+
+* Only single threads should be accessing jobs. This prevents races and sync issues.
+* Data and variables should exist in a single job. Avoid shared (heap) memory locations!
+* Changing jobs should only happen from within the callback, as you can guarantee a
consistent state without needing to spin/block on ns_job_set_*.
+* You may not need mutexes on your data or thread locals, as the job provides the correct
cpu synchronisation guarantees. Consider that each job takes a "root" data node,
then all other allocated variables are referenced there only by the single thread. You can
now dispose of mutexes, as the job will guarantee the synchronisation of this data.
+* Jobs work well if stack variables are used inside the callback functions, rather than
heap.
+
+Some work flows that don't work well here:
+
+* Having threads alter in-flight jobs. This causes race conditions and inconsistencies.
+* Sharing heap data via pointers in jobs. This means you need a mutex on the data, which
causes a serialisation point: Why bother with thread pools if you are just going to
serialise on some data points anyway!
+* Modifying jobs and what they handle. Don't do it! Just ns_job_done on the job, and
create a new one that matches what you want to do.
+* Map reduce: Nunc-Stans doesn't provide a good way to aggregate data on the return,
IE reduce. You may need to provide a queue or some other method to reduce if you were
interested in this.
+
+Examples
+--------
+
+Inside of the nunc-stans project, the tests/cmocka/stress_test.c code is a good example
of a socket server and socket client using nunc-stans that adheres to these principles.

+Libsds {#mainpage}
+======
+
+
+Libsds is the Slapi Data Structures Library. This encapsulates a queue, b+tree
+and set, a copy-on-write b+tree for parallelism.
+
+In the future it will contain a copy-on-write LRU cache as well.
+
+This abstraction exists so that we can reuse this library with Nunc-Stans. The
+queue detects if we are on an x86_64 capable CPU and will build a lock free
+variant if possible.
+
+This library has thorough and complete tests of various complex states to
+assure correct behaviour. It has been tested against NSPR Hashmaps and the
+slapi AVL tree for performance.
+
+Building
+--------
+
+ autoreconf -fiv
+ ./configure [--enable-tests]
+ make
+ [make test]
+ make install

+The Windows kernel build environment is primitive and has a number
+of severe limitations; in particular, all source files must be in
+one directory and it is not possible to choose the output binary type
+(static or dynamic library) from the build command line; rather,
+a string has to be modified in a text file used by the build (!)
+
+To deal with these limitations, it is necessary for a Windows kernel
+build to run a batch file prior to building.
+
+There are two batch files, one for static library builds and the other
+for dynamic library builds.
+
+They are both idempotent; you can run them as often as you like and
+switch between them as often as you want. It's all fine; whenever
+you run one of them, it will take you from whatever state you were
+previously in, into the state you want to be in.
+
+Both batch files copy all the sources file into a single directory,
+"/src/single_dir_for_windows_kernel/".
+
+The static library batch file will then copy "/sources.static" into
+"/src/single_dir_for_windows_kernel/", which will cause a static
+library to be built.
+
+The dynamic library batch file will then copy "/sources.dynamic" into
+"/src/single_dir_for_windows_kernel/", which will cause a dynamic
+library to be built. It will also copy "src/driver_entry.c" into
+"/src/single_dir_for_windows_kernel/", since the linker requires
+the DriverEntry function to exist for dynamic libraries, even
+though it's not used.

+
+ in this queue, there are a fixed number of elements
+ we have a read index and a write index
+ when we write, and thre is space to write, we increment the write index
+ (if no space to write, we just return)
+ when we read, and there are elements to be read, we after reading increment
the read index
+ (if no elements to read, we just return)
+ the problem is - how do we handle wrap around?
+ e.g. when I write, but my write index is now equal to the number of elements
+ the usual solution is to modulus the write index by the nunmber of elements
+ problem is modulus is slow
+ there is a better way
+ first, we restrict the number of elements to be a power of two
+ so imagine we have a 64-bit system and we set the number of elements to be
2^64
+ this gives us a bit pattern of 1000 0000 0000 0000 (...etc, lots of zeros)
+ now (just roll with this for a bit) subtract one from this
+ this gives us a mask (on a two's compliment machine)
+ 0111 1111 1111 1111 (...etc, lots of ones)
+ so what we do now, when we increment an index (think of the write index as the
example)
+ we bitwise and it with the mask
+ now think about thwt happens
+ all the numbers up to 2^64 will be unchanged - their MSB is never set, and we
and with all the other bits
+ but when we finally hit 2^64 and need to roll over... bingo!
+ we drop MSB (which we finally have) and have the value 0!
+ this is exactly what we want
+ bitwise and is much faster than modulus

+/**
+ * \defgroup sds_bptree_cow SDS Copy on Write B+Tree
+ * Thread safe Copy of Write B+Tree. Supports parallel read transactions and serialised
writes with ref counted members.
+ *
+ * This is a very important structure, and is the primary reason to consume this library.
There are a number of important properties
+ * that this tree provides.
+ *
+ * A key concept of this structure is that all values and keys contained have their
lifetimes bound to the life of the tree and it's
+ * nodes. This is due to the transactional nature of the structure. Consider a value that
has been inserted into the tree. We take a
+ * read transaction of the tree in thread A. Thread B now deletes the value that was
inserted. Because A still refers to the value,
+ * it is not freed until thread A closes it's read transaction. This guarantees that
all read transactions are always valid, while
+ * also maintaining that memory can be freed correctly. This has many applications
including the Directory Server plugin subsystem.
+ * We can use this property to guarantee a plugin exists for the life of an operation,
and we only free it once all consumers have
+ * completed their operations with it.
+ *
+ * Another key aspect of this tree is that write transactions *do not* block read
transactions. Reads can be completed in parallel
+ * to writes with complete safety. Write operations are serialised in this structure.
This makes the structure extremely effective
+ * for long read operations with many queries, without interrupting other threads.
+ *
+ * Along with the value and key ownership properties, we can guarantee that the content
of the tree within a read transaction
+ * will *not* be removed or added and will be consistent within the tree (however, we
can't guarantee a user doesn't change the value.)
+ *
+ * As a comparison, the single thread tree is on paper, much faster than the COW version
due to less memory operations. However in a
+ * multi thread use case, the COW version is signifigantly faster *and* safer than a
mutex protected single thread tree.
+ *
+ * This tree can be used as a form of object manager for C, as well as a way to allow
async operations between threads while maintaining,
+ * thread safety across an application. This assumes that the operations are largely
parallel and batch read oriented over write heavy small
+ * transactions.

+ * The copy on write tree instance. This stores the current active reading

+ * b+tree.
+ *
+ * This instance is the most important part of the tree and provides us with memory
safety. Once we
+ * have memory safety, individual transactions are free to garbage collect on their own.
Garbage collection
+ * is coordinated from the instance.
+ *
+ * ## MEMORY SAFTEY
+ *
+ * Within the transaction, we have a small number of important fields. These are:
+ *
+ * - read_lock
+ * - write_lock
+ * - tail_txn
+ * - vacuum_lock
+ *
+ * ### Read Transaction Begin
+ *
+ * At the beginning of a read transaction, we take a rolock on read_lock. This ensures
that on
+ * our working thread, that the correct sequence of barriers for memory consistency of
the tree
+ * is issued.
+ *
+ * Within the read_lock, we use cpu atomics to increment the transaction reference count
by 1.
+ * We then release the read_lock.
+ *
+ * In this way, we allow multiple read transactions to be initiated at the same time,
with the
+ * only serialisation point being the atomic increment.
+ *
+ * While the read transaction is "active" (IE the transaction that is listed in
binst, where new
+ * transactions will reference), the reference count will never go below 1.
+ *
+ * ### Write Transaction
+ *
+ * At the beginning of a write transaction, we take the write_lock mutex. This guarantees
we are
+ * the only writer in the tree at a point in time. Due to the way mutexes work, this
guarantees
+ * our memory barries of the tree are issued, so we see all other writes that have
occured.
+ *
+ * During a write, we store a list of all nodes that were cloned: Both so that we know
who we cloned
+ * *from* but aso what nodes we *created*.
+ *
+ * ### Write Abort
+ *
+ * During a write abort, we release the write lock immediately. We then use the created
node list, and
+ * free all contents as they were never made active.
+ *
+ * ### Write commit
+ *
+ * During a commit, we prepare the transaction by changing it's state flags, and
setting it's reference
+ * count atomically. We relinquish the created list, because we have no need to free the
nodes that are
+ * about to become part of the tree. However, we update the previous transaction with the
"owned" list,
+ * as these are nodes we cloned from: IE these are nodes that serve no *future* role in
the tree, so the
+ * previous transaction is the last point where they are valid and needed - The last
transaction now must
+ * clean up after itself when it's ready to GC!
+ *
+ * We now take the write variant of the rw read_lock. This waits for all in progress read
transactions to
+ * begin, and we take exclusive access of this lock. We then pivot the older transaction
out with our
+ * transaction. The read_lock is released, and read transactions may now resume.
+ *
+ * At this point, we release the write_lock, and a new write may begin.
+ *
+ * We decrement the reference count of the previous transaction which may cause it to
drop to 0. This is
+ * the equivalent of a read transaction close. After this point, the previous
transactions reference
+ * count will only decrement, as previous holders close their transactions. Increment
only occurs from the
+ * active transaction!
+ *
+ * ### Read transaction close.
+ *
+ * When we close a read transaction, we require no locks. We use cpu atomic to set and
fetch the
+ * reference count.
+ *
+ * If the reference count remains positive, we complete, and continue.
+ *
+ * If the reference count drops to 0, we take the vacuum lock. If our reference count is
0 *and*
+ * we are the oldest generation of transaction (ie tail_txn), then we free our
transaction, and all
+ * associated owned nodes, values and keys. We update the tail_txn to be the next oldest
transaction
+ * in the chain and repeat the check.
+ *
+ * While the tail transaction reference count is 0, and the oldest transaction, we
continue to garbage
+ * collect until we find a live transaction. At this point, we release the vacuum lock
and are complete.
+ *
+ * NOTE: Due to this design, if a reference count is dropped to 0 of the tail_txn, while
someone else
+ * is vacuuming there are two states. Either, the other thread does not ees the reference
count drop, and will
+ * release the vacuum lock, allowing us to take it and contine the garbage collection.
Alternately, the other
+ * thread *does* see the reference count drop, and garbage collects the transaction. In
this case, we are blocked
+ * on the vacuum lock, but because the ref count is 0, and the tail_txn pointer is now a
newer generation than
+ * our transaction id, we do *not* attempt the double free.
+ *
+ * ### Usage of the memory safe properties.
+ *
+ * Due to the way the barriers are issued, when you have a read transaction or a write
transaction, you can
+ * guarantee that the tree memory is consistent and correct, and that all values will
remain alive until
+ * you close the transaction. This means you can use this to allow parallel tasks in
complex cases. Directory
+ * Server has such a case with the plugin subsystem. Consider every operation needs a
consistent list of plugins.
+ *
+ * You build a tree of the plugin references (dlopen pointers, reference count, pblock)
and store them.
+ *
+ * When you begin the operation you take a read transaction of this. This means every
plugin in the operation is
+ * guaranteed to be in the tree and held open for the duration of this operation. During
the read, if another thread
+ * commits the delete on a plugin, this drops the ref count, but not below 0 - the
operation can continue safely.
+ *
+ * Once the operation is complete, the transaction is closed. At this point, the vacuum
runs during close, which would
+ * trigger the value free function. This would now actually close the plugin pointers,
values. Additionally, the correct use
+ * of the transaction guarantees the memory content of the plugin is correct due to the
barriers inside of the transaction.

+ * AddressSanitizer: heap-use-after-free on address 0x60300006cc58
+ * ...
+ * #4 0x7fcf7e00bfc4 in job_queue_dequeue
/home/william/development/389ds/nunc-stans/ns_thrpool.c:248
+ *
+ * We have the following issue.
+ * Thread A will attempt to dequeue the pointer at HEAD. Thread B is *also*
+ * about to attempt the same dequeue. When Thread B issues the load barrier
+ * Thread A has not yet dequeue, so element E1 is still the HEAD.
+ *
+ * Thread A now atomically dequeues the item E1. However, Thread B *still*
+ * has not checked the value. Thread A now frees E1. Thread B in umpmc at line
+ * 99 now does the check of next -> value. This causes the heap use after free
+ *
+ * This means that lfds isn't quite safe for this!
+ *
+ * The queue itself is stable and correct, the element isn't dequeued twice,
it's
+ * just that it's possible for a dequeued and freed value to be reffered to by
+ * another thread. The solution I have for this issue is somewhat inspired by
+ * https://aturon.github.io/blog/2015/08/27/epoch/
+ *
+ * In thread local storage, we keep the last few elements we have dequeued
+ * with a flag to point between A/B. This gives us a small generation
+ * ring buffer in essence. When we dequeue an element E1, we store the ptr
+ * into the TLS. Then, we dequeue E2, and store it also into TLS. When we dequeue
+ * E3, we now free E1, and store E3 in the TLS. E4 will free E2 and store E4.
+ *
+ * The benefit of this is that when we go to free E1, we can *guarantee* that
+ * Nothing should still be using it, or reffering to it, since we have taken
+ * The next element out of the queue also!

+# nunc-stans
+
+Nunc Stans is an event framework wrapper that provides a thread pool for event callback
execution. It provides thread safety to event frameworks by isolating and protecting the
thread safe parts from the non-thread safe parts, and allows multi-threaded applications
to use event frameworks that are not thread safe.
+
+It has been primarily developed using http://libevent.org .
+
+# Documentation
+
+Nunc Stans uses doxygen to generate docs from the source. The generated docs are here:
https://firstyear.fedorapeople.org/nunc-stans/index.html .

New subject: [389-ds-base] 02/04: Ticket 49139 - Update makefile and rpm for import
This is an automated email from the git hooks/post-receive script.
firstyear pushed a commit to branch master
in repository 389-ds-base.
commit 617c61e81c9cc3561f3910697fbd3c3be821ded8
Author: William Brown <firstyear(a)redhat.com>
Date: Wed Feb 22 09:48:18 2017 +1000
Ticket 49139 - Update makefile and rpm for import
Fix Description: As we just imported two libraries this changes our
makefile and configure process. We need to correct configure the system
for this, and add these targets to the makefile.
Additionally, because sds and nunc-stans support doxygen we add
this to the build to not lose functionality.

+# revision
+#
+# The implementation number of the current interface.

+#
+# Start with version information of ‘0:0:0’ for each libtool library.
+# Update the version information only immediately before a public release of your
software. More frequent updates are unnecessary, and only guarantee that the current
interface number gets larger faster.
+# If the library source code has changed at all since the last update, then increment
revision (‘c:r:a’ becomes ‘c:r+1:a’).
+# If any interfaces have been added, removed, or changed since the last update,
increment current, and set revision to 0.

age.

Ticket 49142 - bytes vs unicode in plugin tests
Bug Description: In some cases on RHEL7 the plugin_tests can fail
due to the diff with bytes and unicode.This is because the test
uses the legacy backend manager that is not updated for modern
python
Fix Description: Swap the test to the new backend manager that does
handle this.

New subject: [389-ds-base] 04/04: Ticket 49141 - Enable tcmalloc
This is an automated email from the git hooks/post-receive script.
firstyear pushed a commit to branch master
in repository 389-ds-base.
commit f9351cfcb2b9fd9dc6b4c347730207c441215d31
Author: William Brown <firstyear(a)redhat.com>
Date: Wed Feb 22 16:41:07 2017 +1000
Ticket 49141 - Enable tcmalloc
Bug Description: tcmallon conflicts with asan. Additionally,
tcmalloc needs to use -lpthread, so we should guarantee this with
the use of the pkg-config file.
Fix Description: Fix the rpm to use asan *or* tcmalloc. Fix
configure to explode if you try and use both. Fix m4/tcmalloc to
use pkg-config file. Update bundled tcmalloc link to apply to all
binaries to ensure proper behaviour of the server. This also limits
tcmalloc to supported arches (IE exclude s390)
