-
-3) Wait until -
-a) The precident answers CM_REGCONF
-b) All nodes has answered and I'm the candidate -> election won
-c) 30s has passed and I'm the candidate -> election won
-d) TimeToWaitAlive has passed -> Failure to start
-
-When receiving CM_REGCONF
-4) Send CM_NODEINFOREQ to all connected(and connecting) nodes
- reported in CM_REGCONF
-
-5) Wait until -
-a) All CM_NODEINFO_CONF has arrived
-b) TimeToWaitAlive has passed -> Failure to start
-
-6) Send CM_ACKADD to president
-
-7) Wait until -
-a) Receive CM_ADD(CommitNew) from president -> I'm in the qmgr cluster
-b) TimeToWaitAlive has passed -> Failure to start
-
-NOTE:
-30s is hardcoded in 3c.
-TimeToWaitAlive should be atleast X sec greater than 30s. i.e. 30+X sec
-to support "partial starts"
-
-NOTE:
-In 3b, a more correct number (instead of all) would be
-N-NG+1 where N is #nodes and NG is #node groups = (N/R where R is # replicas)
-But Qmgr has no notion about node groups or replicas
-
---- Start phase X - Qmgr -------------------------------------------
-
-President - When accepting a CM_REGREQ
-1) Send CM_REGCONF to starting node
-2) Send CM_ADD(Prepare) to all started nodes + starting node
-3) Send CM_ADD(AddCommit) to all started nodes
-4) Send CM_ADD(CommitNew) to starting node

-- Use same TimeToWaitAliveTimer
-
-1) Check sysfile (DIH_RESTART_REQ)
-2) Read nodes (from Qmgr) P = qmgr president
-
-3) Send CNTR_MASTER_REQ to cntr(P)
- including info in DIH_RESTART_REF/CONF
-
-4) Wait until -
-b) Receiving CNTR_START_CONF -> continue
-b) Receiving CNTR_START_REF -> P = node specified in REF, goto 3
-c) TimeToWaitAlive has passed -> Failure to start

--- Define Backup Req --
-
-1) Get backup definition
- Which tables (all)
-
-2) Open files
- Write table list to CTL - file
-
-3) Get definitions for all tables in backup
-
-4) Get Fragment info
-
-5) Define Backup Conf
-
--- Define Backup Req --
-
--- Abort Backup Req --
-
-1) Report to others
-
-2) Stop logging
-3) Stop file(s)
-4) Stop scan
-
-5) If failure/abort
- Remove files
-
-6) If XXX
- Report to user
-7) Clean up records/stuff
-
--- Abort Backup --
-
-Reasons for aborting:
-
-1a) client abort
-
-1b) slave failure
-
-1c) node failure
-
-Resources to be cleaned up:
-
-Slave responsability:
-
-2a) Close and remove files
-
-2b) Free allocated resources
-
-Master responsability:
-
-2c) Drop triggers

-Unique Hash Index
-=================
-
-unique hash index X on T(A1,...,An) becomes:
-table X with primary key A1,...,An and extra attribute NDB$PK
-
-NDB$PK is primary key of T concatenated at 4-byte boundaries
-
-Protocols:
-
-U - user, initiator of protocol
-C - coordinator
-P - participants, including coordinator node
-
-RT_ - request type, current state
-
-P always replies to C with current RT_ (initially RT_DICT_PREPARE)
-C replies to U at the end

-Ordered Index << under work >>
-=============
-
-created as DICT table, as before, to reuse the code
-
-keep NDB$PK as last attribute (not used but logically correct)
-
-create fragments and attributes must be modified
-
-global metadata? implemented but will use signals anyway
-
-create (after-) insert/update/delete triggers as DICT objects, as before
-
-skip following:
-- create index in TC
-- create triggers in TC
-- read-only constraint on NDB$PK
-
-create (before-) commit trigger in TUP
-
-alter online (in TUX, instead of TC) is needed

-DROP TABLE DESCRIPTION
-----------------------
-
-Drop table is controlled by DICT.
-
-Drop table is used in the following cases in some sort.
- - Drop Table
- - Abort Add Table
- - Drop table in node restart
- - Drop table in system restart
-
-Sequence of Drop Table:
------------------------
-
-1) PREP_DROP_TAB_REQ -> all DICT
- Update schema files on disk
- Table status = DROPPING
-
-2) Controlling DICT only
- Report Table Dropped secured but not yet completed.
-
------- PREP DROP
-
-4) PREP_DROP_TAB_REQ -> all LQHs
-
-5) PREP_DROP_TAB_REQ -> all TCs
-
-6) PREP_DROP_TAB_REQ -> all DIHs
-
-
---- LQH::PREP_DROP_TAB_REQ
-
-*) Mark the table so that no new operations will start
-*) Mark all fragments so that new LCP_FRAG_ORD gets replied directly
- w.o actually checkpointing the fragment
-2) Start waiting for completion
-3) Reply PREP_DROP_TAB_CONF
-
-- After this LQH accepts WAIT_DROP_TAB_REQ
-
---- TC::PREP_DROP_TAB_REQ
-
-1) Mark the table so that no new transactions will start on the table
-2) Send WAIT_DROP_TAB_REQ -> all connected LQH's
-3) Wait for CONF (including NF-handling) from LQH:s
-4) Reply PREP_DROP_TAB_CONF
-
---- DIH::PREP_DROP_TAB_REQ
-
-1) Mark the table so that no new LCP will start on the table
-2) If master (unlink any queued LCP_FRAG_ORD)
-3) Send WAIT_DROP_TAB_REQ -> all connected LQH's
-4) Wait for CONF (including NF-handling) from LQH:s
-5) Reply PREP_DROP_TAB_CONF
-
---- LQH::WAIT_DROP_TAB_REQ
-
-1) Wait for running operations
- Wait for running LCP
-
-2) Reply
-
------- PREP_DROP
-
-7) DROP_TAB_REQ -> all DICT's
- *) DROP_TAB_REQ -> TC
- *) DROP_TAB_REQ -> ACC
- *) DROP_TAB_REQ -> TUP
- *) DROP_TAB_REQ -> DIH
- *) DROP_TAB_REQ -> LQH
- *) Update schema files on disk DROPPED
-
-8) DICT_SCHEMAREQ -> all DICT
- Table status = DROPPED
-
----------------------------------
-
-Sequence of Drop table in node/system restart
----------------------------------------------
-
-In both node and system restart the node receives the schema information from
-the master. If the table is in a state where it needs to complete the drop
-table activity then DBACC, DBTUP, DBDIH, DBDICT is contacted to drop all files
-related to the table. After this the schema information is updated with the new
-state. Since all nodes receive the same schema information there is no risk of
-different behaviour in the various NDB nodes.
-
-API Requirements for Drop Table
--------------------------------
-Definition:
-
- Two tables are NOT the same if they were created with two create
- tables at different points in time, even if the two create tables
- had exactly the same definition.
-
-Requirements:
-
-1. Each operation in a transaction refering to a table (by name or by id)
- should operate on the same table. (This is probably necessary.)
-
-2. Each operation in a transaction refering to a table (by name or by
- id) should operate on the same table as were defined at the
- startTransaction timepoint. (This is not strictly necessary for
- API consistency.)
-
- Example 1:
-
- startTransaction()
-
- drop("TableName1")
- create("TableName1")
-
- getNdbOperation("TableName1")
-
- execute(commit)
-
- - If both requirements 1 and 2 are fulfilled, then this should lead
- to "Error: Invalid Schema Version" or similar error
-
- - If only requirement 1 is fulfilled, then this may be executed
- without any errors.
-
-
- Example 2:
-
- startTransaction()
-
- getNdbOperation("TableName1")
- execute(NoCommit)
-
- drop("TableName1")
- create("TableName1")
-
- getNdbOperation("TableName1")
-
- execute(commit)
-
- - This should always lead to "Error: Invalid Schema Version" or
- similar error.

- * @class dblqh
- *
- * @section secIntro Introduction
- *
- * Dblqh is the coordinator of the LDM. Dblqh is responsible for
- * performing operations on tuples. It does this job with help of
- * Dbacc block (that manages the index structures) and Dbtup
- * (that manages the tuples).
- *
- * Dblqh also keeps track of the participants and acts as a coordinator of
- * 2-phase commits. Logical redo logging is also handled by the Dblqh
- * block.
- *
- * @section secModules Modules
- *
- * The code is partitioned into the following modules:
- * - START / RESTART
- * - Start phase 1: Load our block reference and our processor id
- * - Start phase 2: Initiate all records within the block
- * Connect LQH with ACC and TUP.
- * - Start phase 4: Connect LQH with LQH. Connect every LQH with
- * every LQH in the database system.
- * If initial start, then create the fragment log files.
- * If system restart or node restart,
- * then open the fragment log files and
- * find the end of the log files.
- * - ADD / DELETE FRAGMENT<br>
- * Used by dictionary to create new fragments and delete old fragments.
- * - EXECUTION<br>
- * handles the reception of lqhkeyreq and all processing
- * of operations on behalf of this request.
- * This does also involve reception of various types of attrinfo
- * and keyinfo.
- * It also involves communication with ACC and TUP.
- * - LOG<br>
- * The log module handles the reading and writing of the log.
- * It is also responsible for handling system restart.
- * It controls the system restart in TUP and ACC as well.
- * - TRANSACTION<br>
- * This module handles the commit and the complete phases.
- * - MODULE TO HANDLE TC FAILURE<br>
- * - SCAN<br>
- * This module contains the code that handles a scan of a particular
- * fragment.
- * It operates under the control of TC and orders ACC to
- * perform a scan of all tuples in the fragment.
- * TUP performs the necessary search conditions
- * to ensure that only valid tuples are returned to the application.
- * - NODE RECOVERY<br>
- * Used when a node has failed.
- * It performs a copy of a fragment to a new replica of the fragment.
- * It does also shut down all connections to the failed node.
- * - LOCAL CHECKPOINT<br>
- * Handles execution and control of LCPs
- * It controls the LCPs in TUP and ACC.
- * It also interacts with DIH to control which GCPs are recoverable.
- * - GLOBAL CHECKPOINT<br>
- * Helps DIH in discovering when GCPs are recoverable.
- * It handles the request gcp_savereq that requests LQH to
- * save a particular GCP to disk and respond when completed.
- * - FILE HANDLING<br>
- * With submodules:
- * - SIGNAL RECEPTION
- * - NORMAL OPERATION
- * - FILE CHANGE
- * - INITIAL START
- * - SYSTEM RESTART PHASE ONE
- * - SYSTEM RESTART PHASE TWO,
- * - SYSTEM RESTART PHASE THREE
- * - SYSTEM RESTART PHASE FOUR
- * - ERROR
- * - TEST
- * - LOG

- * - NEXT MBYTE RECORD This log record specifies that there
- * are no more log records in this mbyte.
- *
- *
- * A FILE DESCRIPTOR log record continues as follows:
- * - WORD 1: NO_LOG_DESCRIPTORS This defines the number of
- * descriptors of log files that
- * will follow hereafter (max 32).
- * the log descriptor will describe
- * information about
- * max_gci_completed,
- * max_gci_started and log_lap at
- * every 1 mbyte of the log file
- * since a log file is 16 mbyte
- * always, i need 16 entries in the

- * max_gci_started and log_lap. thus
- * 32 entries per log file
- * descriptor (max 32*48 = 1536,
- * always fits in page 0).
- * - WORD 2: LAST LOG FILE The number of the log file currently
- * open. This is only valid in file 0.
- * - WORD 3 - WORD 18: MAX_GCI_COMPLETED for every 1 mbyte
- * in this log file.

- *
- * Then it continues for NO_LOG_DESCRIPTORS until all subsequent
- * log files (max 32) have been properly described.

- *

- * - WORD 2: HASH VALUE
- * - WORD 3: SCHEMA VERSION
- * - WORD 4: OPERATION TYPE
- * = 0 READ,
- * = 1 UPDATE,

- * - (WORD 7 + KEY_LENGTH) -
- * (WORD 7 + KEY_LENGTH + ATTRINFO_LENGTH - 1) The attrinfo
- *
- * A log record can be spread in several pages in some cases.
- * The next log record always starts immediately after this log record.
- * A log record does however never traverse a 1 mbyte boundary.
- * This is used to ensure that we can always come back if something
- * strange occurs in the log file.
- * To ensure this we also have log records which only records
- * the next log record.
- *
- *

- * - WORD 2: TRANSACTION ID PART 2
- * - WORD 3: FRAGMENT ID OF THE OPERATION
- * - WORD 4: TABLE ID OF THE OPERATION
- * - WORD 5: THE FILE NUMBER OF THE PREPARE RECORD

- * - WORD 8: THE STOP PAGE NUMBER OF THE PREPARE RECORD
- * - WORD 9: GLOBAL CHECKPOINT OF THE TRANSACTION
- *
- *
- * An ABORT TRANSACTION log record continues as follows:

- * - WORD 2: TRANSACTION ID PART 2
- *
- *

- *
- *
- * A NEXT LOG RECORD log record continues as follows:
- * - There is no more information needed.
- * The next log record will always refer to the start of the next page.

-/* ######################################################################### *
- * ####### SCAN MODULE ####### *
- * ######################################################################### *
-
- The application orders a scan of a table. We divide the scan into a scan on
- each fragment. The scan uses the primary replicas since the scan might be
- used for an update in a separate transaction.
-
- Scans are always done as a separate transaction. Locks from the scan
- can be overtaken by another transaction. Scans can never lock the entire
- table. Locks are released immediately after the read has been verified
- by the application. There is not even an option to leave the locks.
- The reason is that this would hurt real-time behaviour too much.
-
- -# The first step in handling a scan of a table is to receive all signals
- defining the scan. If failures occur during this step we release all
- resource and reply with SCAN_TABREF providing the error code.
- If system load is too high, the request will not be allowed.
-
- -# The second step retrieves the number of fragments that exist in the
- table. It also ensures that the table actually exist. After this,
- the scan is ready to be parallelised. The idea is that the receiving
- process (hereafter called delivery process) will start up a number
- of scan processes. Each of these scan processes will
- independently scan one fragment at a time. The delivery
- process object is the scan record and the scan process object is
- the scan fragment record plus the scan operation record.
-
- -# The third step is thus performed in parallel. In the third step each
- scan process retrieves the primary replica of the fragment it will
- scan. Then it starts the scan as soon as the load on that node permits.
-
- The LQH returns either when it retrieved the maximum number of tuples or
- when it has retrived at least one tuple and is hindered by a lock to
- retrieve the next tuple. This is to ensure that a scan process never
- can be involved in a deadlock situation.
-
- When the scan process receives a number of tuples to report to the
- application it checks the state of the delivery process. Only one delivery
- at a time is handled by the application. Thus if the delivery process
- has already sent a number of tuples to the application this set of tuples
- are queued.
-
- When the application requests the next set of tuples it is immediately
- delivered if any are queued, otherwise it waits for the next scan
- process that is ready to deliver.
-
-
- ERROR HANDLING
-
- As already mentioned it is rather easy to handle errors before the scan
- processes have started. In this case it is enough to release the resources
- and send SCAN_TAB_REF.
-
- If an error occurs in any of the scan processes then we have to stop all
- scan processes. We do however only stop the delivery process and ask
- the api to order us to close the scan. The reason is that we can easily
- enter into difficult timing problems since the application and this
- block is out of synch we will thus always start by report the error to
- the application and wait for a close request. This error report uses the
- SCAN_TABREF signal with a special error code that the api must check for.
-
-
- CLOSING AN ACTIVE SCAN
-
- The application can close a scan for several reasons before it is completed.
- One reason was mentioned above where an error in a scan process led to a
- request to close the scan. Another reason could simply be that the
- application found what it looked for and is thus not interested in the
- rest of the scan.
-
- IT COULD ALSO BE DEPENDENT ON INTERNAL ERRORS IN THE API.
-
- When a close scan request is received, all scan processes are stopped and all
- resources belonging to those scan processes are released. Stopping the scan
- processes most often includes communication with an LQH where the local scan
- is controlled. Finally all resources belonging to the scan is released and
- the SCAN_TABCONF is sent with an indication of that the scan is closed.
-
-
- CLOSING A COMPLETED SCAN
-
- When all scan processes are completed then a report is sent to the
- application which indicates that no more tuples can be fetched.
- The application will send a close scan and the same action as when
- closing an active scan is performed.
- In this case it will of course not find any active scan processes.
- It will even find all scan processes already released.
-
- The reason for requiring the api to close the scan is the same as above.
- It is to avoid any timing problems due to that the api and this block
- is out of synch.

-// Methods to handle execution of TUPKEYREQ + ATTRINFO.
-//
-// Module Execution Manager
-//
-// The TUPKEYREQ signal is central to this block. This signal is used
-// by everybody that needs to read data residing in DBTUP. The data is
-// read using an interpreter approach.
-//
-// Operations only needing to read execute a simplified version of the
-// interpreter where the only instruction is read Attribute to send.
-// Operations only needing to update the record (insert or update)
-// execute a simplified version of the interpreter where the only
-// instruction is write Attribute.
-//
-// Currently TUPKEYREQ is used in the following situations.
-// 1) Normal transaction execution. Can be any of the types described
-// below.
-// 2) Execution of fragment redo log during system restart.
-// In this situation there will only be normal updates, inserts
-// and deletes performed.
-// 3) A special type of normal transaction execution is to write the
-// records arriving from the primary replica in the node restart
-// processing. This will always be normal write operations which
-// are translated to inserts or updates before arriving to TUP.
-// 4) Scan processing. The scan processing will use normal reads or
-// interpreted reads in their execution. There will be one TUPKEYREQ
-// signal for each record processed.
-// 5) Copy fragment processing. This is a special type of scan used in the
-// primary replica at system restart. It reads the entire reads and
-// converts those to writes to the starting node. In this special case
-// LQH acts as an API node and receives also the ATTRINFO sent in the
-// TRANSID_AI signals.
-//
-// Signal Diagram:
-//
-// In Signals:
-// -----------
-//
-// Logically there is one request TUPKEYREQ which requests to read/write data
-// of one tuple in the database. Since the definition of what to read and write
-// can be bigger than the maximum signal size we segment the signal. The definition
-// of what to read/write/interpreted program is sent before the TUPKEYREQ signal.
-//
-// ---> ATTRINFO
-// ...
-// ---> ATTRINFO
-// ---> TUPKEYREQ
-// The number of ATTRINFO signals can be anything between 0 and upwards.
-// The total size of the ATTRINFO is not allowed to be more than 16384 words.
-// There is always one and only one TUPKEYREQ.
-//
-// Response Signals (successful case):
-//
-// Simple/Dirty Read Operation
-// ---------------------------
-//
-// <---- TRANSID_AI (to API)
-// ...
-// <---- TRANSID_AI (to API)
-// <---- READCONF (to API)
-// <---- TUPKEYCONF (to LQH)
-// There is always exactly one READCONF25 sent last. The number of
-// TRANSID_AI is dependent on how much that was read. The maximum size
-// of the ATTRINFO sent back is 16384 words. The signals are sent
-// directly to the application with an address provided by the
-// TUPKEYREQ signal.
-// A positive response signal is also sent to LQH.
-//
-// Normal Read Operation
-// ---------------------
-//
-// <---- TRANSID_AI (to API)
-// ...
-// <---- TRANSID_AI (to API)
-// <---- TUPKEYCONF (to LQH)
-// The number of TRANSID_AI is dependent on how much that was read.
-// The maximum size of the ATTRINFO sent back is 16384 words. The
-// signals are sent directly to the application with an address
-// provided by the TUPKEYREQ signal.
-// A positive response signal is also sent to LQH.
-//
-// Normal update/insert/delete operation
-// -------------------------------------
-//
-// <---- TUPKEYCONF
-// After successful updating of the tuple LQH is informed of this.
-//
-// Delete with read
-// ----------------
-//
-// Will behave as a normal read although it also prepares the
-// deletion of the tuple.
-//
-// Interpreted Update
-// ------------------
-//
-// <---- TRANSID_AI (to API)
-// ...
-// <---- TRANSID_AI (to API)
-// <---- TUP_ATTRINFO (to LQH)
-// ...
-// <---- TUP_ATTRINFO (to LQH)
-// <---- TUPKEYCONF (to LQH)
-//
-// The interpreted Update contains five sections:
-// The first section performs read Attribute operations
-// that send results back to the API.
-//
-// The second section executes the interpreted program
-// where data from attributes can be updated and it
-// can also read attribute values into the registers.
-//
-// The third section performs unconditional updates of
-// attributes.
-//
-// The fourth section can read the attributes to be sent to the
-// API after updating the record.
-//
-// The fifth section contains subroutines used by the interpreter
-// in the second section.
-//
-// All types of interpreted programs contains the same five sections.
-// The only difference is that only interpreted updates can update
-// attributes. Interpreted inserts are not allowed.
-//
-// Interpreted Updates have to send back the information about the
-// attributes they have updated. This information will be shipped to
-// the log and also to any other replicas. Thus interpreted updates
-// are only performed in the primary replica. The fragment redo log
-// in LQH will contain information so that normal update/inserts/deletes
-// can be performed using TUPKEYREQ.
-//
-// Interpreted Read
-// ----------------
-//
-// From a signalling point of view the Interpreted Read behaves as
-// as a Normal Read. The interpreted Read is often used by Scan's.
-//
-// Interpreted Delete
-// ------------------
-//
-// <---- TUPKEYCONF
-// After successful prepartion to delete the tuple LQH is informed
-// of this.
-//
-// Interpreted Delete with Read
-// ----------------------------
-//
-// From a signalling point of view an interpreted delete with read
-// behaves as a normal read.
-//
-// Continuation after successful case:
-//
-// After a read of any kind the operation record is ready to be used
-// again by a new operation.
-//
-// Any updates, inserts or deletes waits for either of two messages.
-// A commit specifying that the operation is to be performed for real
-// or an abort specifying that the operation is to be rolled back and
-// the record to be restored in its original format.
-//
-// This is handled by the module Transaction Manager.
-//
-// Response Signals (unsuccessful case):
-//
-// <---- TUPKEYREF (to LQH)
-// A signal is sent back to LQH informing about the unsuccessful
-// operation. In this case TUP waits for an abort signal to arrive
-// before the operation record is ready for the next operation.
-// This is handled by the Transaction Manager.

-// Module Transaction Manager
-//
-// The Transaction Manager module is responsible for the commit

-//
-// Commit Operation:
-// ----------------
-//
-// Failures in commit processing is not allowed since that would
-// leave the database in an unreliable state. Thus the only way
-// to handle failures in commit processing is to crash the node.
-//
-// TUP_COMMITREQ can only be received in the wait state after a

-//
-// Commit of Delete:
-// -----------------
-//
-// This will actually perform the deletion of the record unless
-// other operations also are connected to the record. In this case
-// we will set the delete state on the record that becomes the owner
-// of the record.
-//
-// Commit of Update:
-// ----------------
-//
-// We will release the copy record where the original record was kept.
-// Also here we will take special care if more operations are updating
-// the record simultaneously.

-// Signal Diagram:
-// ---> TUP_ABORTREQ (from LQH)
-// <---- TUP_ABORTCONF (to LQH)

-// Failures in abort processing is not allowed since that would
-// leave the database in an unreliable state. Thus the only way
-// to handle failures in abort processing is to crash the node.
-//
-// Abort messages can arrive at any time. It can arrive even before
-// anything at all have arrived of the operation. It can arrive after
-// receiving a number of ATTRINFO but before TUPKEYREQ has been received.
-// It must arrive after that we sent TUPKEYREF in response to TUPKEYREQ
-// and finally it can arrive after successfully performing the TUPKEYREQ
-// in all cases including the read case.

-// 4) Page Memory Manager (buddy algorithm)
-//
-// The following data structures in Dbtup is used by the Page Memory
-// Manager.
-//
-// cfreepageList[16]
-// Pages with a header
-//
-// The cfreepageList is 16 free lists. Free list 0 contains chunks of
-// pages with 2^0 (=1) pages in each chunk. Free list 1 chunks of 2^1
-// (=2) pages in each chunk and so forth upto free list 15 which
-// contains chunks of 2^15 (=32768) pages in each chunk.
-// The cfreepageList array contains the pointer to the first chunk
-// in each of those lists. The lists are doubly linked where the
-// first page in each chunk contains the next and previous references
-// in position ZPAGE_NEXT_CLUST_POS and ZPAGE_PREV_CLUST_POS in the
-// page header.
-// In addition the leading page and the last page in each chunk is marked
-// with a state (=ZFREE_COMMON) in position ZPAGE_STATE_POS in page
-// header. This state indicates that the page is the leading or last page
-// in a chunk of free pages. Furthermore the leading and last page is
-// also marked with a reference to the leading (=ZPAGE_FIRST_CLUST_POS)
-// and the last page (=ZPAGE_LAST_CLUST_POS) in the chunk.
-//
-// The aim of these data structures is to enable a free area handling of
-// free pages based on a buddy algorithm. When allocating pages it is
-// performed in chunks of pages and the algorithm tries to make the
-// chunks as large as possible.
-// This manager is invoked when fragments lack internal page space to
-// accomodate all the data they are requested to store. It is also
-// invoked when fragments deallocate page space back to the free area.
-//
-// The following routines are part of the external interface:
-// void
-// allocConsPages(Uint32 noOfPagesToAllocate, #In
-// Uint32& noOfPagesAllocated, #Out
-// Uint32& retPageRef) #Out
-// void
-// returnCommonArea(Uint32 retPageRef, #In
-// Uint32 retNoPages) #In
-//
-// allocConsPages tries to allocate noOfPagesToAllocate pages in one chunk.
-// If this fails it delivers a chunk as large as possible. It returns the
-// i-value of the first page in the chunk delivered, if zero pages returned
-// this i-value is undefined. It also returns the size of the chunk actually
-// delivered.
-//
-// returnCommonArea is used when somebody is returning pages to the free area.
-// It is used both from internal routines and external routines.
-//
-// The following routines are private routines used to support the
-// above external interface:
-// removeCommonArea()
-// insertCommonArea()
-// findFreeLeftNeighbours()
-// findFreeRightNeighbours()
-// Uint32
-// nextHigherTwoLog(Uint32 input)
-//
-// nextHigherTwoLog is a support routine which is a mathematical function with
-// an integer as input and an integer as output. It calculates the 2-log of
-// (input + 1). If the 2-log of (input + 1) is larger than 15 then the routine
-// will return 15. It is part of the external interface since it is also used
-// by other similar memory management algorithms.
-//
-// External dependencies:
-// None.
-//
-// Side Effects:
-// Apart from the above mentioned data structures there are no more
-// side effects other than through the subroutine parameters in the
-// external interface.

-Operations, tuples, versions
-============================
-
-Operation types.
-
-INSERT insert new original tuple, or insert after delete
-UPDATE update
-DELETE delete
-
-Following need not be considered here.
-
-READ does not change tuples or versions
-WRITE turns into INSERT or UPDATE in LQH
-
-We use more specific names in some cases:
-
-first/INSERT initial insert of new tuple
-delete/INSERT INSERT preceded by DELETE
-DELETE/last DELETE as last operation
-DELETE/insert DELETE followed by INSERT
-
-Tuple + op Can be followed by
--------------- ------------------
-does not exist first/INSERT
-tuple exists UPDATE DELETE
-INSERT UPDATE DELETE
-UPDATE UPDATE DELETE
-DELETE delete/INSERT
-
-Operations on same tuple are kept in doubly linked list until
-commit or abort. The links at both ends are RNIL i.e. the list
-is not circular. The links are:
-
-nextActiveOp the operation BEFORE this one, in event order
-prevActiveOp the operation AFTER this one, in event order
-
-Operations are done on the "original tuple" i.e. the tuple is
-modified in place. If an operation is about to write over data
-in original tuple, it first copies the tuple to a "copy tuple".
-
-Operation Copy tuple
---------- ----------
-first/INSERT no
-delete/INSERT yes (this is in effect an update)
-UPDATE yes
-DELETE no
-
-The operation points to the tuples via:
-
-realPageId page i-value of original tuple
-pageOffset word offset of original tuple on the page
-realPageIdC page i-value of copy tuple or RNIL is no copy exists
-pageOffsetC word offset of copy tuple on the page
-
-The original tuple and the copy tuple (if any) point back to
-the operation via word 0. In copy tuple this pointer is never
-changed. In original tuple however it always points to the LATEST
-existing operation i.e. the one with prevActiveOp == RNIL.
-Thus word 0 of original tuple is changed on 2 occasions:
-
-- when a new operation is added to the list
-- when commit or abort removes the latest operation
-
-Note that commit/abort of operations occurs in random order.
-The list is adjusted accordingly.
-
-Versions
---------
-
-Tuple version is stored in tuple word 1. A new original tuple
-gets version 0. The version is incremented by each new operation
-which makes a copy tuple. Version number wraps around at 15 bits.
-
-When a copy tuple is made, the version in original tuple is copied
-to copy tuple as part of tuple data. This takes place before
-the version in original tuple is updated.
-
-Each operation record contains tuple version called tupVersion.
-
-- at insert of new original tuple, tupVersion is set to 0
-
-- if tuple already exists, the FIRST operation (in event order)
- reads tupVersion from tuple word 1. If the operation is
- not DELETE, the version is incremented
-
-- subsequent operation reads tupVersion from the operation
- BEFORE it (nextActiveOp). If this subsequent operation is
- not DELETE, the version is incremented
-
-When the operation writes the tuple it sets word 1 to tupVersion.
-In detail, per operation type, where INSERT is divided into
-insert of new original tuple and insert after delete:
-
-Operation Copy Increment Set version in original
---------- ---- --------- -----------------------
-first/INSERT no no yes, to 0
-delete/INSERT yes yes yes
-UPDATE yes yes yes
-DELETE no no no
-
-Thus an existing version is incremented if and only if
-a copy tuple is made.
-
-Ordered index maintenance
--------------------------
-
-Each index entry has logical tuple address and tuple version.
-Index entries are added during prepare phase (when each operation
-is executed) and removed during commit or abort phase.
-
-Access to correct tuple version (original or copy) is required
-in TUX which reads index key values 1) to check that at least one
-is not null 2) to do tree search 3) to set min/max prefixes.
-See "Read attributes" below.
-
-An additional complication is that commit/abort of operations
-arrives in random order. So we cannot check for, for example,
-DELETE/insert by looking at prevActiveOp.
-
-Phase Op Action Version in
------ -- ------ ----------
-prepare INSERT add op and original
-prepare UPDATE add op and original
-prepare DELETE none -
-
-commit first/INSERT none -
-commit delete/INSERT remove copy tuple 1)
-commit UPDATE remove copy tuple 1)
-commit DELETE/last remove op and original
-commit DELETE/insert none -
-
-abort INSERT remove op
-abort UPDATE remove op
-abort DELETE none -
-
-1) alternatively, store prevTupVersion in operation record.
-
-Read attributes, query status
------------------------------
-
-TUP_READ_ATTRS signal (or equivalent direct call) reads attribute
-values. Input is logical address of original tuple and tuple
-version. The steps are:
-
-- Translate logical address to physical address of original tuple.
-
-- If version of original tuple in word 1 is right, stop.
-
-- Otherwise word 0 points to LATEST not yet deleted operation.
- Walk through operation list via nextActiveOp.
-
-- If an operation on the list has realPageIdC == RNIL, skip it.
-
-- Otherwise find copy tuple via realPageIdC, pageOffsetC.
- If the version of the copy tuple in word 1 is right, stop.
-
-- Call readAttributes() on the tuple found (original or copy).
-
-In short, the version must exist in some not yet deleted tuple,
-either in original or in some copy.
-
-Note that this must work during all phases since index code
-needs to read index key attributes from correct tuple version in
-each add/remove operation.
-
-TUP_QUERY_TH signal (or equivalent direct call) does same search
-for tuple version. It is called from index scan and returns info
-used to decide if the scan can see the tuple.
-
-This signal may also be called during any phase since commit/abort
-of all operations is not done in one time-slice.
-
-Commit and abort
-----------------
-
-[ hairy stuff ]
-
-Problems
---------
-
-Current abort code can destroy a tuple version too early. This
-happens in test case "ticuur" (insert-commit-update-update-rollback),
-if abort of first update arrives before abort of second update.

- * In this change 6, 2 and 4 must be there, all others are optional.
- * We will start by proving a Lemma.
- * Lemma:
- * The height of the sub-trees 1 and 7 and the maximum height of the
- * threes from 3 and 5 are all the same.
- * Proof:
- * maxheight(3,5) is defined as the maximum height of 3 and 5.
- * If height(7) > maxheight(3,5) then the AVL condition is ok and we
- * don't need to perform a rotation.
- * If height(7) < maxheight(3,5) then the balance of 6 would be at least
- * -3 which cannot happen in an AVL tree even before a rotation.
- * Thus we conclude that height(7) == maxheight(3,5)
- *
- * The next step is to prove that the height of 1 is equal to maxheight(3,5).
- * If height(1) - 1 > maxheight(3,5) then we would have
- * balance in 6 equal to -3 at least which cannot happen in an AVL-tree.
- * If height(1) - 1 = maxheight(3,5) then we should have solved the
- * unbalance with a single rotate and not with a double rotate.
- * If height(1) + 1 = maxheight(3,5) then we would be doing a rotate
- * with node 2 as the root of the rotation.
- * If height(1) + k = maxheight(3,5) where k >= 2 then the tree could not have
- * been an AVL-tree before the insert or delete.
- * Thus we conclude that height(1) = maxheight(3,5)
- *
- * Thus we conclude that height(1) = maxheight(3,5) = height(7).
- *
- * Observation:
- * The balance of node 4 before the rotation can be any (-1, 0, +1).
- *
- * The following changes are needed:
- * Node 6:
- * 1) Changes parent from 0 -> 4
- * 2) 1 - i link stays the same
- * 3) i side link is derived from 1 - i side link from 4
- * 4) Side is set to 1 - i
- * 5) Balance change:
- * If balance(4) == 0 then balance(6) = 0
- * since height(3) = height(5) = maxheight(3,5) = height(7)
- * If balance(4) == +1 then balance(6) = 0
- * since height(5) = maxheight(3,5) = height(7)
- * If balance(4) == -1 then balance(6) = 1
- * since height(5) + 1 = maxheight(3,5) = height(7)
- *
- * Node 2:
- * 1) Changes parent from 6 -> 4
- * 2) i side link stays the same
- * 3) 1 - i side link is derived from i side link of 4
- * 4) Side is set to i (thus not changed)
- * 5) Balance change:
- * If balance(4) == 0 then balance(2) = 0
- * since height(3) = height(5) = maxheight(3,5) = height(1)
- * If balance(4) == -1 then balance(2) = 0
- * since height(3) = maxheight(3,5) = height(1)
- * If balance(4) == +1 then balance(6) = 1
- * since height(3) + 1 = maxheight(3,5) = height(1)
- *
- * Node 4:
- * 1) Inherits parent from 6
- * 2) i side link is 2
- * 3) 1 - i side link is 6
- * 4) Side is inherited from 6
- * 5) Balance(4) = 0 independent of previous balance
- * Proof:
- * If height(1) = 0 then only 2, 4 and 6 are involved and then it is
- * trivially true.
- * If height(1) >= 1 then we are sure that 1 and 7 exist with the same
- * height and that if 3 and 5 exist they are of the same height as 1 and
- * 7 and thus we know that 4 is balanced since newheight(2) = newheight(6).
- *
- * If Node 3 exists:
- * 1) Change parent from 4 to 2
- * 2) Change side from i to 1 - i
- *
- * If Node 5 exists:
- * 1) Change parent from 4 to 6
- * 2) Change side from 1 - i to i
- *
- * If Node 0 exists:
- * 1) previous link to 6 is replaced by link to 4 on proper side
- *
- * Node 1 and 7 needs no changes at all.
- *
- * Some additional requires are that balance(2) = - balance(6) = -1/+1 since
- * otherwise we would do a single rotate.
- *
- * The balance(6) is -1 if i == 0 and 1 if i == 1

-<h2>NDB Ordered Index Status</h2>
-<p>
-<h3>Alpha release Jan 30, 2004</h3>
-<p>
-<ul>
- <li>
- Up to 32 index attributes of any type, possibly nullable.
- <li>
- Index build i.e. table need not be empty.
- <li>
- Logging NOT done, index rebuilt at system restart.
- <li>
- Single range scan with lower and upper bounds.
- <li>
- Scan with locking: read latest, read for update.
- <li>
- LIMITED number of parallel scans.
- <li>
- Total result set NOT in index key order.
- <li>
- NDB ODBC optimizer to use ordered index for equality but NOT for ranges.
- <li>
- MySQL optimizer to use ordered index for equality and ranges.
-</ul>
-<p>
-As an example, consider following index on integer attributes.
-<p>
-<tt>SQL&gt;create index X on T (A, B, C) nologging;</tt>
-<p>
-Single range scan means that bounds are set on
-an initial sequence of index keys, and all but last is an equality.
-<br>
-For example following scans are supported (the last 2 not via NDB ODBC).
-<p>
-<tt>SQL&gt;select * from T where A = 1;</tt>
-<br>
-<tt>SQL&gt;select * from T where A = 1 and B = 10 and C = 20;</tt>
-<br>
-<tt>SQL&gt;select * from T where A &lt; 10;</tt>
-<br>
-<tt>SQL&gt;select * from T where A = 1 and 10 &lt; B and B &lt; 20;</tt>
-<p>
-Following scans are NOT supported:
-<p>
-<tt>SQL&gt;select * from T where B = 1;</tt>
-<br>
-<tt>SQL&gt;select * from T where A &lt; 10 and B &lt; 20;</tt>

-<p>
-1) No locking and bounds must be on non-nullable key attributes.
-<br>
-2) Currently table must be empty when index is created.
-<br>
-3) Currently limited to 11 simultaneous per fragment.

-UTIL Protocols
---------------
-Transactions are executed in two phases:
-1) PREPARE
-2) EXECUTE
-
-
-PREPARE PHASE
--------------
-1) ** REQUEST **
- Client (any block) requests prepare service from Util:
-
- Client --UTIL_PREPARE_REQ--> Util
- ...
- Client --UTIL_PREPARE_REQ--> Util
-
-2) ** DICTINFO **
- Util requests Dict for information about table:
-
- Util --GET_TABINFOREQ--> Dict
-
- Util <--DICTTABINFO-- Dict
- ...
- Util <--DICTTABINFO-- Dict
-
-3) ** PREPARE **
- Operation (= transaction) is prepared (DbUtil::prepareOperation)
-
- a) AttrMapping is created (a map used to read of the
- actual execute request attribute values and put them in KEYINFO)
-
- b) TC Signal train is prepared
-
-4) ** CONFIRM **
- Request is confirmed
-
- Client <--UTIL_PREPARE_CONF-- Util
-
-
-EXECUTE PHASE
--------------
-1) Client (any block) requests execute service from Util:
- (Execute can be INSERT, DELETE,...)
-
- Client --UTIL_EXECUTE_REQ--> Util (Multi-signals not yet implemented)
- ...
- Client --UTIL_EXECUTE_REQ--> Util
-
-2) Util --TCKEYREQ--> tc
-
- Util --KEYINFO--> tc (sometimes) (Not yet implemented)
- ...
- Util --KEYINFO--> tc
-
- Util --ATTRINFO--> tc (sometimes)
- ...
- Util --ATTRINFO--> tc
-
-3) Util <--TCKEYCONF-- tc
-
- Util --TC_COMMIT_ACK-->tc (sometimes)
-
- (in parallel with)
-
- Util <--TRANSID_AI-- tc (sometimes)
- ...
- Util <--TRANSID_AI-- tc
