+
+Begin Concurrent
+================
+
+## Overview
+
+Usually, SQLite allows at most one writer to proceed concurrently. The
+BEGIN CONCURRENT enhancement allows multiple writers to process write
+transactions simultanously if the database is in "wal" or "wal2" mode,
+although the system still serializes COMMIT commands.
+
+When a write-transaction is opened with "BEGIN CONCURRENT", actually 
+locking the database is deferred until a COMMIT is executed. This means
+that any number of transactions started with BEGIN CONCURRENT may proceed
+concurrently. The system uses optimistic page-level-locking to prevent
+conflicting concurrent transactions from being committed.
+
+When a BEGIN CONCURRENT transaction is committed, the system checks whether 
+or not any of the database pages that the transaction has read have been
+modified since the BEGIN CONCURRENT was opened. In other words - it asks 
+if the transaction being committed operates on a different set of data than
+all other concurrently executing transactions. If the answer is "yes, this
+transaction did not read or modify any data modified by any concurrent
+transaction", then the transaction is committed as normal. Otherwise, if the
+transaction does conflict, it cannot be committed and an SQLITE&#95;BUSY&#95;SNAPSHOT
+error is returned. At this point, all the client can do is ROLLBACK the
+transaction.
+
+If SQLITE&#95;BUSY&#95;SNAPSHOT is returned, messages are output via the sqlite3&#95;log
+mechanism indicating the page and table or index on which the conflict
+occurred. This can be useful when optimizing concurrency.
+
+## Application Programming Notes
+
+In order to serialize COMMIT processing, SQLite takes a lock on the database
+as part of each COMMIT command and releases it before returning. At most one
+writer may hold this lock at any one time. If a writer cannot obtain the lock,
+it uses SQLite's busy-handler to pause and retry for a while:
+
+  <a href=https://www.sqlite.org/c3ref/busy_handler.html>
+      https://www.sqlite.org/c3ref/busy_handler.html
+  </a>
+
+If there is significant contention for the writer lock, this mechanism can be
+inefficient. In this case it is better for the application to use a mutex or
+some other mechanism that supports blocking to ensure that at most one writer
+is attempting to COMMIT a BEGIN CONCURRENT transaction at a time. This is
+usually easier if all writers are part of the same operating system process.
+
+If all database clients (readers and writers) are located in the same OS
+process, and if that OS is a Unix variant, then it can be more efficient to
+the built-in VFS "unix-excl" instead of the default "unix". This is because it
+uses more efficient locking primitives.
+
+The key to maximizing concurrency using BEGIN CONCURRENT is to ensure that
+there are a large number of non-conflicting transactions. In SQLite, each
+table and each index is stored as a separate b-tree, each of which is
+distributed over a discrete set of database pages. This means that:
+
+  * Two transactions that write to different sets of tables never 
+    conflict, and that
+
+  * Two transactions that write to the same tables or indexes only 
+    conflict if the values of the keys (either primary keys or indexed 
+    rows) are fairly close together. For example, given a large 
+    table with the schema:
+
+      <pre>     CREATE TABLE t1(a INTEGER PRIMARY KEY, b BLOB);</pre>
+
+    writing two rows with adjacent values for "a" probably will cause a
+    conflict (as the two keys are stored on the same page), but writing two
+    rows with vastly different values for "a" will not (as the keys will likly
+    be stored on different pages).
+
+Note that, in SQLite, if values are not explicitly supplied for an INTEGER
+PRIMARY KEY, as for example in:
+
+>
+     INSERT INTO t1(b) VALUES(<blob-value>);
+
+then monotonically increasing values are assigned automatically. This is
+terrible for concurrency, as it all but ensures that all new rows are 
+added to the same database page. In such situations, it is better to
+explicitly assign random values to INTEGER PRIMARY KEY fields.
+
+This problem also comes up for non-WITHOUT ROWID tables that do not have an
+explicit INTEGER PRIMARY KEY column. In these cases each table has an implicit
+INTEGER PRIMARY KEY column that is assigned increasing values, leading to the
+same problem as omitting to assign a value to an explicit INTEGER PRIMARY KEY
+column.
+
+For both explicit and implicit INTEGER PRIMARY KEYs, it is possible to have
+SQLite assign values at random (instead of the monotonically increasing
+values) by writing a row with a rowid equal to the largest possible signed
+64-bit integer to the table. For example:
+
+     INSERT INTO t1(a) VALUES(9223372036854775807);
+
+Applications should take care not to malfunction due to the presence of such
+rows.
+
+The nature of some types of indexes, for example indexes on timestamp fields,
+can also cause problems (as concurrent transactions may assign similar
+timestamps that will be stored on the same db page to new records). In these
+cases the database schema may need to be rethought to increase the concurrency
+provided by page-level-locking.

-
-## Statically Linking The TCL Library
-
-Some utility programs associated with SQLite need to be linked
-with TCL in order to function.  The [sqlite3_analyzer.exe program](https://sqlite.org/sqlanalyze.html)
-is an example.  You can build as described above, and then
-enter:
-
-> ~~~~
-nmake /f Makefile.msc sqlite3_analyzer.exe
-~~~~
-
-And you will end up with a working executable.  However, that executable
-will depend on having the "tcl86.dll" library somewhere on your %PATH%.
-Use the following steps to build an executable that has the TCL library
-statically linked so that it does not depend on separate DLL:
-
-  1.  Use the appropriate "Command Prompt" window - either x86 or
-      x64, depending on whether you want a 32-bit or 64-bit executable.
-
-  2.  Untar the TCL source tarball into a fresh directory.  CD into
-      the "win/" subfolder.
-
-  3.  Run: `nmake /f makefile.vc OPTS=nothreads,static shell`
-
-
-  4.  CD into the "Release*" subfolder that is created (note the
-      wildcard - the full name of the directory might vary).  There
-      you will find the "tcl86s.lib" file.  Copy this file into the
-      same directory that you put the "tcl86.lib" on your initial
-      installation.  (In this document, that directory is
-      "`C:\Tcl32\lib`" for 32-bit builds and
-      "`C:\Tcl\lib`" for 64-bit builds.)
-
-  5.  CD into your SQLite source code directory and build the desired
-      utility program, but add the following extra arguments to the
-      nmake command line:
-      <blockquote><pre>
-      CCOPTS="-DSTATIC_BUILD" LIBTCL="tcl86s.lib netapi32.lib user32.lib"
-      </pre></blockquote>
-      <p>So, for example, to build a statically linked version of
-      sqlite3_analyzer.exe, you might type:
-      <blockquote><pre>
-      nmake /f Makefile.msc CCOPTS="-DSTATIC_BUILD" LIBTCL="tcl86s.lib netapi32.lib user32.lib" sqlite3_analyzer.exe
-      </pre></blockquote>
-
-  6.  After your executable is built, you can verify that it does not
-      depend on the TCL DLL by running:
-      <blockquote><pre>
-      dumpbin /dependents sqlite3_analyzer.exe

-# 1. Overview
-
-testrunner.tcl is a Tcl script used to run multiple SQLite tests using 
-multiple jobs. It supports the following types of tests:
-
-  *  Tcl test scripts.
-
-  *  Tests run with [make] commands. Specifically, at time of writing, 
-     [make fuzztest], [make mptest], [make sourcetest] and [make threadtest].
-
-testrunner.tcl pipes the output of all tests and builds run into log file
-**testrunner.log**, created in the cwd directory. Searching this file for
-"failed" is a good way to find the output of a failed test.
-
-testrunner.tcl also populates SQLite database **testrunner.db**. This database
-contains details of all tests run, running and to be run. A useful query
-might be:
-
-```
-  SELECT * FROM script WHERE state='failed'
-```
-
-Running the command:
-
-```
-  ./testfixture $(TESTDIR)/testrunner.tcl status
-```
-
-in the directory containing the testrunner.db database runs various queries
-to produce a succinct report on the state of a running testrunner.tcl script.
-Running:
-
-```
-  watch ./testfixture $(TESTDIR)/testrunner.tcl status
-```
-
-in another terminal is a good way to keep an eye on a long running test.
-
-Sometimes testrunner.tcl uses the [testfixture] binary that it is run with
-to run tests (see "Binary Tests" below). Sometimes it builds testfixture and
-other binaries in specific configurations to test (see "Source Tests").
-
-<a name=binary_tests></a>
-# 2. Binary Tests
-
-The commands described in this section all run various combinations of the Tcl
-test scripts using the [testfixture] binary used to run the testrunner.tcl
-script (i.e. they do not invoke the compiler to build new binaries, or the
-[make] command to run tests that are not Tcl scripts). The procedure to run
-these tests is therefore:
-
-  1. Build the "testfixture" (or "testfixture.exe" for windows) binary using
-     whatever method seems convenient.
-
-  2. Test the binary built in step 1 by running testrunner.tcl with it, 
-     perhaps with various options.
-
-The following sub-sections describe the various options that can be
-passed to testrunner.tcl to test binary testfixture builds.
-
-<a name=organization_tests></a>
-## 2.1. Organization of Tcl Tests
-
-Tcl tests are stored in files that match the pattern *\*.test*. They are
-found in both the $TOP/test/ directory, and in the various sub-directories
-of the $TOP/ext/ directory of the source tree. Not all *\*.test* files
-contain Tcl tests - a handful are Tcl scripts designed to invoke other
-*\*.test* files.
-
-The **veryquick** set of tests is a subset of all Tcl test scripts in the
-source tree. In includes most tests, but excludes some that are very slow.
-Almost all fault-injection tests (those that test the response of the library
-to OOM or IO errors) are excluded. It is defined in source file 
-*test/permutations.test*.
-
-The **full** set of tests includes all Tcl test scripts in the source tree.
-To run a "full" test is to run all Tcl test scripts that can be found in the
-source tree.
-
-File *permutations.test* defines various test "permutations". A permutation
-consists of:
-
-  *  A subset of Tcl test scripts, and 
-
-  *  Runtime configuration to apply before running each test script 
-     (e.g. enabling auto-vacuum, or disable lookaside).
-
-Running **all** tests is to run all tests in the full test set, plus a dozen
-or so permutations. The specific permutations that are run as part of "all"
-are defined in file *testrunner_data.tcl*.
-
-<a name=run_tests></a>
-## 2.2. Commands to Run Tests
-
-To run the "veryquick" test set, use either of the following:
-
-```
-  ./testfixture $TESTDIR/testrunner.tcl
-  ./testfixture $TESTDIR/testrunner.tcl veryquick
-```
-
-To run the "full" test suite:
-
-```
-  ./testfixture $TESTDIR/testrunner.tcl full
-```
-
-To run the subset of the "full" test suite for which the test file name matches
-a specified pattern (e.g. all tests that start with "fts5"), either of:
-
-```
-  ./testfixture $TESTDIR/testrunner.tcl fts5%
-  ./testfixture $TESTDIR/testrunner.tcl 'fts5*'
-```
-
-Strictly speaking, for a test to be run the pattern must match the script
-filename, not including the directory, using the rules of Tcl's 
-\[string match\] command. Except that before the matching is done, any "%"
-characters specified as part of the pattern are transformed to "\*".
-
-
-To run "all" tests (full + permutations):
-
-```
-  ./testfixture $TESTDIR/testrunner.tcl all
-```
-
-<a name=binary_test_failures></a>
-## 2.3. Investigating Binary Test Failures
-
-If a test fails, testrunner.tcl reports name of the Tcl test script and, if
-applicable, the name of the permutation, to stdout. This information can also
-be retrieved from either *testrunner.log* or *testrunner.db*.
-
-If there is no permutation, the individual test script may be run with:
-
-```
-  ./testfixture $PATH_TO_SCRIPT
-```
-
-Or, if the failure occured as part of a permutation:
-
-```
-  ./testfixture $TESTDIR/testrunner.tcl $PERMUTATION $PATH_TO_SCRIPT
-```
-
-TODO: An example instead of "$PERMUTATION" and $PATH\_TO\_SCRIPT?
-
-<a name=source_code_tests></a>
-# 3. Source Code Tests
-
-The commands described in this section invoke the C compiler to build 
-binaries from the source tree, then use those binaries to run Tcl and
-other tests. The advantages of this are that:
-
-  *  it is possible to test multiple build configurations with a single
-     command, and 
-
-  *  it ensures that tests are always run using binaries created with the
-     same set of compiler options.
-
-The testrunner.tcl commands described in this section may be run using
-either a *testfixture* (or testfixture.exe) build, or with any other Tcl
-shell that supports SQLite 3.31.1 or newer via "package require sqlite3".
-
-TODO: ./configure + Makefile.msc build systems.
-
-<a name=commands_to_run_tests></a>
-## 3.1. Commands to Run SQLite Tests
-
-The **mdevtest** command is equivalent to running the veryquick tests and
-the [make fuzztest] target once for each of two --enable-all builds - one 
-with debugging enabled and one without:
-
-```
-  tclsh $TESTDIR/testrunner.tcl mdevtest
-```
-
-In other words, it is equivalent to running:
-
-```
-  $TOP/configure --enable-all --enable-debug
-  make fuzztest
-  make testfixture
-  ./testfixture $TOP/test/testrunner.tcl veryquick
-
-  # Then, after removing files created by the tests above:
-  $TOP/configure --enable-all OPTS="-O0"
-  make fuzztest
-  make testfixture
-  ./testfixture $TOP/test/testrunner.tcl veryquick
-```
-
-The **sdevtest** command is identical to the mdevtest command, except that the
-second of the two builds is a sanitizer build. Specifically, this means that
-OPTS="-fsanitize=address,undefined" is specified instead of OPTS="-O0":
-
-```
-  tclsh $TESTDIR/testrunner.tcl sdevtest
-```
-
-The **release** command runs lots of tests under lots of builds. It runs
-different combinations of builds and tests depending on whether it is run
-on Linux, Windows or OSX. Refer to *testrunner\_data.tcl* for the details
-of the specific tests run.
-
-```
-  tclsh $TESTDIR/testrunner.tcl release
-```
-
-As with <a href=#source code tests>source code tests</a>, one or more patterns
-may be appended to any of the above commands (mdevtest, sdevtest or release).
-In that case only Tcl tests (no fuzz or other tests) that match the specified
-pattern are run. For example, to run the just the Tcl rtree tests in all 
-builds and configurations supported by "release":
-
-```
-  tclsh $TESTDIR/testrunner.tcl release rtree%
-```
-
-<a name=zipvfs_tests></a>
-## 3.2. Running ZipVFS Tests
-
-testrunner.tcl can build a zipvfs-enabled testfixture and use it to run
-tests from the Zipvfs project with the following command:
-
-```
-  tclsh $TESTDIR/testrunner.tcl --zipvfs $PATH_TO_ZIPVFS
-```
-
-This can be combined with any of "mdevtest", "sdevtest" or "release" to
-test both SQLite and Zipvfs with a single command:
-
-```
-  tclsh $TESTDIR/testrunner.tcl --zipvfs $PATH_TO_ZIPVFS mdevtest
-```
-
-<a name=source_code_test_failures></a>
-## 3.3. Investigating Source Code Test Failures
-
-Investigating a test failure that occurs during source code testing is a
-two step process:
-
-  1. Recreating the build configuration in which the test failed, and
-
-  2. Re-running the actual test.
-
-To recreate a build configuration, use the testrunner.tcl **script** command
-to create a build script. A build script is a bash script on Linux or OSX, or
-a dos \*.bat file on windows. For example:
-
-```
-  # Create a script that recreates build configuration "Device-One" on 
-  # Linux or OSX:
-  tclsh $TESTDIR/testrunner.tcl script Device-One > make.sh 
-
-  # Create a script that recreates build configuration "Have-Not" on Windows:
-  tclsh $TESTDIR/testrunner.tcl script Have-Not > make.bat 
-```
-
-The generated bash or \*.bat file script accepts a single argument - a makefile
-target to build. This may be used either to run a [make] command test directly,
-or else to build a testfixture (or testfixture.exe) binary with which to
-run a Tcl test script, as <a href=#binary_test_failures>described above</a>.
-
-<a name=testrunner_options></a>
-# 4. Extra testrunner.tcl Options
-
-The testrunner.tcl script options in this section may be used with both source
-code and binary tests.
-
-The **--buildonly** option instructs testrunner.tcl just to build the binaries
-required by a test, not to run any actual tests. For example:
-
-```
-  # Build binaries required by release test.
-  tclsh $TESTDIR/testrunner.tcl --buildonly release"
-```
-
-The **--dryrun** option prevents testrunner.tcl from building any binaries
-or running any tests. Instead, it just writes the shell commands that it
-would normally execute into the testrunner.log file. Example:
-
-```
-  # Log the shell commmands that make up the mdevtest test.
-  tclsh $TESTDIR/testrunner.tcl --dryrun mdevtest"
-```
-
-<a name=cpu_cores></a>
-# 5. Controlling CPU Core Utilization
-
-When running either binary or source code tests, testrunner.tcl reports the
-number of jobs it intends to use to stdout. e.g.
-
-```
-  $ ./testfixture $TESTDIR/testrunner.tcl
-  splitting work across 16 jobs
-  ... more output ...
-```
-
-By default, testfixture.tcl attempts to set the number of jobs to the number 
-of real cores on the machine. This can be overridden using the "--jobs" (or -j)
-switch:
-
-```
-  $ ./testfixture $TESTDIR/testrunner.tcl --jobs 8
-  splitting work across 8 jobs
-  ... more output ...
-```
-
-The number of jobs may also be changed while an instance of testrunner.tcl is
-running by exucuting the following command from the directory containing the
-testrunner.log and testrunner.db files:
-
-```
-  $ ./testfixture $TESTDIR/testrunner.tcl njob $NEW_NUMBER_OF_JOBS
-```

 One-to-One(-ish) Mapping to C

 This JNI binding aims to provide as close to a 1-to-1 experience with
-the C API as cross-language semantics allow. Interface changes are
+the C API as cross-language semantics allow. Exceptions are
 necessarily made where cross-language semantics do not allow a 1-to-1,
 and judiciously made where a 1-to-1 mapping would be unduly cumbersome
-to use in Java. In all cases, this binding makes every effort to
-provide semantics compatible with the C API documentation even if the
-interface to those semantics is slightly different.  Any cases which
-deviate from those semantics (either removing or adding semantics) are
-clearly documented.
+to use in Java.

-Where it makes sense to do so for usability, Java-side overloads are
-provided which accept or return data in alternative forms or provide
-sensible default argument values. In all such cases they are thin
-proxies around the corresponding C APIs and do not introduce new
-semantics.
-
-In a few cases, Java-specific capabilities have been added in
-new APIs, all of which have "_java" somewhere in their names.
-Examples include:
-
- `sqlite3_result_java_object()`
- `sqlite3_column_java_object()`
- `sqlite3_value_java_object()`
-
-which, as one might surmise, collectively enable the passing of
-arbitrary Java objects from user-defined SQL functions through to the
-caller.

-Golden Rule: Garbage Collection Cannot Free SQLite Resources
+Golden Rule: _Never_ Throw from Callbacks
 ------------------------------------------------------------------------

-It is important that all databases and prepared statement handles get
-cleaned up by client code. A database cannot be closed if it has open
-statement handles. `sqlite3_close()` fails if the db cannot be closed
-whereas `sqlite3_close_v2()` recognizes that case and marks the db as
-a "zombie," pending finalization when the library detects that all
-pending statements have been closed. Be aware that Java garbage
-collection _cannot_ close a database or finalize a prepared statement.
-Those things require explicit API calls.
+JNI bindings which accept client-defined functions _must never throw
+exceptions_ unless _very explicitly documented_ as being
+throw-safe. Exceptions are generally reserved for higher-level
+bindings which are constructed to specifically deal with them and
+ensure that they do not leak C-level resources. Some of the JNI
+bindings are provided as Java functions which expect this rule to
+always hold.

-Classes for which it is sensible support Java's `AutoCloseable`
-interface so can be used with try-with-resources constructs.
-
-
-Golden Rule #2: _Never_ Throw from Callbacks (Unless...)
+UTF-8(-ish)
 ------------------------------------------------------------------------

-All routines in this API, barring explicitly documented exceptions,
-retain C-like semantics. For example, they are not permitted to throw
-or propagate exceptions and must return error information (if any) via
-result codes or `null`. The only cases where the C-style APIs may
-throw is through client-side misuse, e.g. passing in a null where it
-may cause a `NullPointerException`. The APIs clearly mark function
-parameters which should not be null, but does not generally actively
-defend itself against such misuse. Some C-style APIs explicitly accept
-`null` as a no-op for usability's sake, and some of the JNI APIs
-deliberately return an error code, instead of segfaulting, when passed
-a `null`.
+SQLite internally uses UTF-8 encoding, whereas Java natively uses
+UTF-16.  Java JNI has routines for converting to and from UTF-8, _but_
+Java uses what its docs call "[modified UTF-8][modutf8]." Care must be
+taken when converting Java strings to UTF-8 to ensure that the proper
+conversion is performed. In short,
+`String.getBytes(StandardCharsets.UTF_8)` performs the proper
+conversion in Java, and there is no JNI C API for that conversion
+(JNI's `NewStringUTF()` returns MUTF-8).

-Client-defined callbacks _must never throw exceptions_ unless _very
-explitly documented_ as being throw-safe. Exceptions are generally
-reserved for higher-level bindings which are constructed to
-specifically deal with them and ensure that they do not leak C-level
-resources. In some cases, callback handlers are permitted to throw, in
-which cases they get translated to C-level result codes and/or
-messages. If a callback which is not permitted to throw throws, its
-exception may trigger debug output but will otherwise be suppressed.
+Known consequences and limitations of this discrepancy include:

-The reason some callbacks are permitted to throw and others not is
-because all such callbacks act as proxies for C function callback
-interfaces and some of those interfaces have no error-reporting
-mechanism. Those which are capable of propagating errors back through
-the library convert exceptions from callbacks into corresponding
-C-level error information. Those which cannot propagate errors
-necessarily suppress any exceptions in order to maintain the C-style
-semantics of the APIs.
+- Names of databases, tables, and collations must not contain
+  characters which differ in MUTF-8 and UTF-8, or certain APIs will
+  mis-translate them on their way between languages. APIs which
+  transfer other client-side data to Java take extra care to
+  convert the data at the cost of performance.

+     Achtung: this interface is subject to change because the current
+     approach to mapping the passed-in natives back to Java is
+     uncomfortably quirky.
+
+     Called by sqlite3 for various tracing operations, as per
+     sqlite3_trace_v2(). Note that this interface elides the 2nd
+     argument to the native trace callback, as that role is better
+     filled by instance-local state.
+
+     The 2nd argument to this function, if non-0, will be a native
+     pointer to either an sqlite3 or sqlite3_stmt object, depending on
+     the first argument (see below). Client code can pass it to the
+     sqlite3 resp. sqlite3_stmt constructor to create a wrapping
+     object, if necessary. This API does not do so by default because
+     tracing can be called frequently, creating such a wrapper for
+     each call is comparatively expensive, and the objects are
+     probably only seldom useful.
+
+     The final argument to this function is the "X" argument
+     documented for sqlite3_trace() and sqlite3_trace_v2(). Its type
+     depends on value of the first argument:
+
+     - SQLITE_TRACE_STMT: pNative is a sqlite3_stmt. pX is a string
+       containing the prepared SQL, with one caveat: JNI only provides
+       us with the ability to convert that string to MUTF-8, as
+       opposed to standard UTF-8, and is cannot be ruled out that that
+       difference may be significant for certain inputs. The

-   org.sqlite.jni.capi.sqlite3_stmt}, and {@link

-
-   <p>When used in the context of Java interfaces which are called
-   from the C APIs, this annotation communicates that the C API will
-   never pass a null value to the callback for that parameter.</p>
-
-   <p>Passing a null, for this annotation's definition of null, for

-

-
-   <p><b>Undefined behaviour:</b> the JNI build uses the {@code
-   SQLITE_ENABLE_API_ARMOR} build flag, meaning that the C code
-   invoked with invalid NULL pointers and the like will not invoke
-   undefined behavior in the conventional C sense, but may, for
-   example, return result codes which are not documented for the
-   affected APIs or may otherwise behave unpredictably. In no known
-   cases will such arguments result in C-level code dereferencing a

-   memory. In other words, they may cause unexpected behavior but
-   should never cause an outright crash or security issue.</p>
-
-   <p>Note that the C-style API does not throw any exceptions on its

-   semantics, but it may trigger NullPointerExceptions (or similar) if
-   passed a null for a parameter flagged with this annotation.</p>
