- * page.h contains a detailed description of the page format.
- *
- * Normally, keys and data are accessed from offset tables in the top of
- * each page which point to the beginning of the key and data.  There are
- * four flag values which may be stored in these offset tables which indicate
- * the following:
- *
- *
- * OVFLPAGE	Rather than a key data pair, this pair contains
- *		the address of an overflow page.  The format of
- *		the pair is:
- *		    OVERFLOW_PAGE_NUMBER OVFLPAGE
- *
- * PARTIAL_KEY	This must be the first key/data pair on a page
- *		and implies that page contains only a partial key.
- *		That is, the key is too big to fit on a single page
- *		so it starts on this page and continues on the next.
- *		The format of the page is:
- *		    KEY_OFF PARTIAL_KEY OVFL_PAGENO OVFLPAGE
- *
- *		    KEY_OFF -- offset of the beginning of the key
- *		    PARTIAL_KEY -- 1
- *		    OVFL_PAGENO - page number of the next overflow page
- *		    OVFLPAGE -- 0
- *
- * FULL_KEY	This must be the first key/data pair on the page.  It
- *		is used in two cases.
- *
- *		Case 1:
- *		    There is a complete key on the page but no data
- *		    (because it wouldn't fit).  The next page contains
- *		    the data.
- *
- *		    Page format it:
- *		    KEY_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
- *
- *		    KEY_OFF -- offset of the beginning of the key
- *		    FULL_KEY -- 2
- *		    OVFL_PAGENO - page number of the next overflow page
- *		    OVFLPAGE -- 0
- *
- *		Case 2:
- *		    This page contains no key, but part of a large
- *		    data field, which is continued on the next page.
- *
- *		    Page format it:
- *		    DATA_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
- *
- *		    KEY_OFF -- offset of the beginning of the data on
- *				this page
- *		    FULL_KEY -- 2
- *		    OVFL_PAGENO - page number of the next overflow page
- *		    OVFLPAGE -- 0
- *
- * FULL_KEY_DATA
- *		This must be the first key/data pair on the page.
- *		There are two cases:
- *
- *		Case 1:
- *		    This page contains a key and the beginning of the
- *		    data field, but the data field is continued on the
- *		    next page.
- *
- *		    Page format is:
- *		    KEY_OFF FULL_KEY_DATA OVFL_PAGENO DATA_OFF
- *
- *		    KEY_OFF -- offset of the beginning of the key
- *		    FULL_KEY_DATA -- 3
- *		    OVFL_PAGENO - page number of the next overflow page
- *		    DATA_OFF -- offset of the beginning of the data
- *
- *		Case 2:
- *		    This page contains the last page of a big data pair.
- *		    There is no key, only the  tail end of the data
- *		    on this page.
- *
- *		    Page format is:

- * In recno, there are two meanings to the on-page "deleted" flag.  If we're

- * return DB_KEYEMPTY if they're explicitly requested..  If not re-numbering
- * records, it means that the record was implicitly created, or was deleted.
- * We skip over implicitly created or deleted records if doing a cursor "next"
- * or "prev", and return DB_KEYEMPTY if they're explicitly requested.
- *
- * If we're re-numbering records, then we have to detect in the cursor that
- * a record was deleted, and adjust the cursor as necessary on the next get.
- * If we're not re-numbering records, then we can detect that a record has
- * been deleted by looking at the actual on-page record, so we completely
- * ignore the cursor's delete flag.  This is different from the B+tree code.
- * It also maintains whether the cursor references a deleted record in the
- * cursor, and it doesn't always check the on-page value.

- *
- * BEGIN	<RECORD_TYPE>
- * ARG|STRING|POINTER	<variable name>	<variable type> <printf format>
- * ...
- * END
- * ARG the argument is a simple parameter of the type *	specified.
- * DBT the argument is a DBT (db.h) containing a length and pointer.
- * PTR the argument is a pointer to the data type specified; the entire
- *     type should be logged.
- *
- * There are a set of shell scripts of the form xxx.sh that generate c
- * code and or h files to process these.  (This is probably better done
- * in a single PERL script, but for now, this works.)
- *
- * The DB recovery system requires the following three fields appear in
- * every record, and will assign them to the per-record-type structures
- * as well as making them the first parameters to the appropriate logging

- * The basis of the hash algorithm was taken from an idea sent by email to the
- * IEEE Posix P1003.2 mailing list from Phong Vo (kpv@research.att.com) and
- * Glenn Fowler (gsf@research.att.com).  Landon Curt Noll (chongo@toad.com)
- * later improved on their algorithm.
- *
- * The magic is in the interesting relationship between the special prime
- * 16777619 (2^24 + 403) and 2^32 and 2^8.
- *
- * This hash produces the fewest collisions of any function that we've seen so
- * far, and works well on both numbers and strings.

-//
-// C++ assumptions:
-//
-// To ensure portability to many platforms, both new and old, we make
-// few assumptions about the C++ compiler and library.  For example,
-// we do not expect STL, templates or namespaces to be available.  The
-// "newest" C++ feature used is exceptions, which are used liberally
-// to transmit error information.  Even the use of exceptions can be
-// disabled at runtime, see setErrorModel().
-//
-// C++ naming conventions:
-//
-//  - All top level class names start with Db.
-//  - All class members start with lower case letter.
-//  - All private data members are suffixed with underscore.
-//  - Use underscores to divide names into multiple words.
-//  - Simple data accessors are named with get_ or set_ prefix.
-//  - All method names are taken from names of functions in the C
-//    layer of db (usually by dropping a prefix like "db_").
-//    These methods have the same argument types and order,
-//    other than dropping the explicit arg that acts as "this".
-//
-// As a rule, each DbFoo object has exactly one underlying DB_FOO struct
-// (defined in db.h) associated with it.  In many cases, we inherit directly
-// from the DB_FOO structure to make this relationship explicit.  Often,
-// the underlying C layer allocates and deallocates these structures, so
-// there is no easy way to add any data to the DbFoo class.  When you see
-// a comment about whether data is permitted to be added, this is what
-// is going on.  Of course, if we need to add data to such C++ classes
-// in the future, we will arrange to have an indirect pointer to the
-// DB_FOO struct (as some of the classes already have).

-// Since these defines use "private/public" labels, and leave the access

- * There are three ways we do locking in the mpool code:
- *
- * Locking a handle mutex to provide concurrency for DB_THREAD operations.
- * Locking the region mutex to provide mutual exclusion while reading and
- *    writing structures in the shared region.
- * Locking buffer header mutexes during I/O.
- *
- * The first will not be further described here.  We use the shared mpool
- * region lock to provide mutual exclusion while reading/modifying all of
- * the data structures, including the buffer headers.  We use a per-buffer
- * header lock to wait on buffer I/O.  The order of locking is as follows:
- *
- * Searching for a buffer:
- *	Acquire the region lock.
- *	Find the buffer header.
- *	Increment the reference count (guarantee the buffer stays).
- *	While the BH_LOCKED flag is set (I/O is going on) {
- *	    Release the region lock.
- *		Explicitly yield the processor if it's not the first pass
- *		through this loop, otherwise, we can simply spin because
- *		we'll be simply switching between the two locks.
- *	    Request the buffer lock.
- *	    The I/O will complete...
- *	    Acquire the buffer lock.
- *	    Release the buffer lock.
- *	    Acquire the region lock.
- *	}
- *	Return the buffer.
- *
- * Reading/writing a buffer:
- *	Acquire the region lock.
- *	Find/create the buffer header.
- *	If reading, increment the reference count (guarantee the buffer stays).
- *	Set the BH_LOCKED flag.
- *	Acquire the buffer lock (guaranteed not to block).
- *	Release the region lock.
- *	Do the I/O and/or initialize the buffer contents.
- *	Release the buffer lock.
- *	    At this point, the buffer lock is available, but the logical
- *	    operation (flagged by BH_LOCKED) is not yet completed.  For
- *	    this reason, among others, threads checking the BH_LOCKED flag
- *	    must loop around their test.
- *	Acquire the region lock.
- *	Clear the BH_LOCKED flag.
- *	Release the region lock.
- *	Return/discard the buffer.
- *
- * Pointers to DB_MPOOL, MPOOL, DB_MPOOLFILE and MPOOLFILE structures are not
- * reacquired when a region lock is reacquired because they couldn't have been
- * closed/discarded and because they never move in memory.

- * This file defines three types of data structures: lists, tail queues,
- * and circular queues.
- *
- * A list is headed by a single forward pointer (or an array of forward
- * pointers for a hash table header). The elements are doubly linked
- * so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before
- * or after an existing element or at the head of the list. A list
- * may only be traversed in the forward direction.
- *
- * A tail queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or
- * after an existing element, at the head of the list, or at the end of
- * the list. A tail queue may only be traversed in the forward direction.
- *
- * A circle queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or after
- * an existing element, at the head of the list, or at the end of the list.
- * A circle queue may be traversed in either direction, but has a more
- * complex end of list detection.

-# @(#)README	10.2 (Sleepycat) 11/25/97
-
-Resource locking routines: lock based on a db_mutex_t.  All this gunk
-(including trying to make assembly code portable), is necessary because
-System V semaphores require system calls for uncontested locks and we
-don't want to make two system calls per resource lock.
-
-First, this is how it works.  The db_mutex_t structure contains a resource
-test-and-set lock (tsl), a file offset, a pid for debugging and statistics
-information.
-
-If HAVE_SPINLOCKS is defined (i.e. we know how to do test-and-sets for
-this compiler/architecture combination), we try and lock the resource tsl
-__db_tsl_spins times.  If we can't acquire the lock that way, we use a
-system call to sleep for 10ms, 20ms, 40ms, etc.  (The time is bounded at
-1 second, just in case.)  Using the timer backoff means that there are
-two assumptions: that locks are held for brief periods (never over system
-calls or I/O) and that locks are not hotly contested.
-
-If HAVE_SPINLOCKS is not defined, i.e. we can't do test-and-sets, we use
-a file descriptor to do byte locking on a file at a specified offset.  In
-this case, ALL of the locking is done in the kernel.  Because file
-descriptors are allocated per process, we have to provide the file
-descriptor as part of the lock/unlock call.  We still have to do timer
-backoff because we need to be able to block ourselves, i.e. the lock
-manager causes processes to wait by having the process acquire a mutex
-and then attempting to re-acquire the mutex.  There's no way to use kernel
-locking to block yourself, i.e. if you hold a lock and attempt to
-re-acquire it, the attempt will succeed.
-
-Next, let's talk about why it doesn't work the way a reasonable person
-would think it should work.
-
-Ideally, we'd have the ability to try to lock the resource tsl, and if
-that fails, increment a counter of waiting processes, then block in the
-kernel until the tsl is released.  The process holding the resource tsl
-would see the wait counter when it went to release the resource tsl, and
-would wake any waiting processes up after releasing the lock.  This would
-actually require both another tsl (call it the mutex tsl) and
-synchronization between the call that blocks in the kernel and the actual
-resource tsl.  The mutex tsl would be used to protect accesses to the
-db_mutex_t itself.  Locking the mutex tsl would be done by a busy loop,
-which is safe because processes would never block holding that tsl (all
-they would do is try to obtain the resource tsl and set/check the wait
-count).  The problem in this model is that the blocking call into the
-kernel requires a blocking semaphore, i.e. one whose normal state is
-locked.
-
-The only portable forms of locking under UNIX are fcntl(2) on a file
-descriptor/offset, and System V semaphores.  Neither of these locking
-methods are sufficient to solve the problem.
-
-The problem with fcntl locking is that only the process that obtained the
-lock can release it.  Remember, we want the normal state of the kernel
-semaphore to be locked.  So, if the creator of the db_mutex_t were to
-initialize the lock to "locked", then a second process locks the resource
-tsl, and then a third process needs to block, waiting for the resource
-tsl, when the second process wants to wake up the third process, it can't
-because it's not the holder of the lock!  For the second process to be
-the holder of the lock, we would have to make a system call per
-uncontested lock, which is what we were trying to get away from in the
-first place.
-
-There are some hybrid schemes, such as signaling the holder of the lock,
-or using a different blocking offset depending on which process is
-holding the lock, but it gets complicated fairly quickly.  I'm open to
-suggestions, but I'm not holding my breath.
-
-Regardless, we use this form of locking when HAVE_SPINLOCKS is not
-defined, (i.e. we're locking in the kernel) because it doesn't have the
-limitations found in System V semaphores, and because the normal state of
-the kernel object in that case is unlocked, so the process releasing the
-lock is also the holder of the lock.
-
-The System V semaphore design has a number of other limitations that make
-it inappropriate for this task.  Namely:
-
-First, the semaphore key name space is separate from the file system name
-space (although there exist methods for using file names to create
-semaphore keys).  If we use a well-known key, there's no reason to believe
-that any particular key will not already be in use, either by another
-instance of the DB application or some other application, in which case
-the DB application will fail.  If we create a key, then we have to use a
-file system name to rendezvous and pass around the key.
-
-Second, System V semaphores traditionally have compile-time, system-wide
-limits on the number of semaphore keys that you can have.  Typically, that
-number is far too low for any practical purpose.  Since the semaphores
-permit more than a single slot per semaphore key, we could try and get
-around that limit by using multiple slots, but that means that the file
-that we're using for rendezvous is going to have to contain slot
-information as well as semaphore key information, and we're going to be
-reading/writing it on every db_mutex_t init or destroy operation.  Anyhow,
-similar compile-time, system-wide limits on the numbers of slots per
-semaphore key kick in, and you're right back where you started.
-
-My fantasy is that once POSIX.1 standard mutexes are in wide-spread use,
-we can switch to them.  My guess is that it won't happen, because the
-POSIX semaphores are only required to work for threads within a process,
-and not independent processes.
-
-Note: there are races in the statistics code, but since it's just that,
-I didn't bother fixing them.  (The fix requires a mutex tsl, so, when/if
-this code is fixed to do rational locking (see above), then change the
-statistics update code to acquire/release the mutex tsl.

-Berkeley DB log dump utility.  This utility dumps out a DB log in human
-readable form, a record at a time, to assist in recovery and transaction
-abort debugging.
-
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
-commit.awk	Output transaction ID of committed transactions.
-
-count.awk	Print out the number of log records for transactions
-		that we encountered.
-
-pgno.awk	Take a comma-separated list of page numbers and spit
-		out all the log records that affect those page numbers.
-
-range.awk	Print out a range of the log.
-
-status.awk	Read through db_printlog output and list the transactions
-		encountered, and whether they commited or aborted.
-
-txn.awk		Print out all the records for a comma-separated list of
-		transaction IDs.
