Improvements to FORDELETE processing, including bug fixes and adding assert() statements to help verify correct operation. Closed-Leaf check-in: 46080b04 user: drh tags: btree-fordelete-flag
2016-01-27
15:49
Add assert() statements on the nExtraDelete variable in vdbe.c to try to verify that the FORDELETE and IDXDELETE flags are being generated correctly. Those flags are not currently generated correctly, and so the assert()s trip on this check-in. check-in: dde1db0d user: drh tags: fordelete-assert

Merge all recent trunk enhancements. check-in: 9a71d56d user: drh tags: btree-fordelete-flag

Performance improvements for fts5, particularly detail=col mode. check-in: a3d7b8ac user: dan tags: trunk
2016-01-21
17:06
Add a new hint bit on the flags parameter of sqlite3BtreeDelete(). The new BTREE_IDXDELETE bit indicates that the call is to delete an index entry corresponding to a table row that has already been deleted. check-in: ac2cbadd user: drh tags: btree-fordelete-flag

This package contains:

 * the SQLite library amalgamation (single file) source code distribution,
 * the shell.c file used to build the sqlite3 shell too, and
 * the sqlite3.h and sqlite3ext.h header files required to link programs
   and sqlite extensions against the installed libary.
 * autoconf/automake installation infrastucture.













The generic installation instructions for autoconf/automake are found
in the INSTALL file.

The following SQLite specific boolean options are supported:

  --enable-readline           use readline in shell tool   [default=yes]
  --enable-threadsafe         build a thread-safe library  [default=yes]
  --enable-dynamic-extensions support loadable extensions  [default=yes]

The default value for the CFLAGS variable (options passed to the C 
compiler) includes debugging symbols in the build, resulting in larger
binaries than are necessary. Override it on the configure command
line like this:

  $ CFLAGS="-Os" ./configure

to produce a smaller installation footprint.

Other SQLite compilation parameters can also be set using CFLAGS. For
example:

  $ CFLAGS="-Os -DSQLITE_OMIT_TRIGGERS" ./configure

 * the shell.c file used to build the sqlite3 shell too, and
 * the sqlite3.h and sqlite3ext.h header files required to link programs

   Windows.

SUMMARY OF HOW TO BUILD
=======================

  Unix:      ./configure; make
  Windows:   nmake /f Makefile.msc

BUILDING ON POSIX
=================

The generic installation instructions for autoconf/automake are found
in the INSTALL file.

The following SQLite specific boolean options are supported:

  --enable-readline           use readline in shell tool   [default=yes]
  --enable-threadsafe         build a thread-safe library  [default=yes]
  --enable-dynamic-extensions support loadable extensions  [default=yes]

The default value for the CFLAGS variable (options passed to the C
compiler) includes debugging symbols in the build, resulting in larger
binaries than are necessary. Override it on the configure command
line like this:

  $ CFLAGS="-Os" ./configure

to produce a smaller installation footprint.

Other SQLite compilation parameters can also be set using CFLAGS. For
example:

  $ CFLAGS="-Os -DSQLITE_OMIT_TRIGGERS" ./configure


BUILDING WITH MICROSOFT VISUAL C++
==================================

To compile for Windows using Microsoft Visual C++:

  $ nmake /f Makefile.msc

Using Microsoft Visual C++ 2005 (or later) is recommended.  Several Windows
platform variants may be built by adding additional macros to the NMAKE
command line.

Building for WinRT 8.0
----------------------

  FOR_WINRT=1

Using Microsoft Visual C++ 2012 (or later) is required.  When using the
above, something like the following macro will need to be added to the
NMAKE command line as well:

  "NSDKLIBPATH=%WindowsSdkDir%\..\8.0\lib\win8\um\x86"

Building for WinRT 8.1
----------------------

  FOR_WINRT=1

Using Microsoft Visual C++ 2013 (or later) is required.  When using the
above, something like the following macro will need to be added to the
NMAKE command line as well:

  "NSDKLIBPATH=%WindowsSdkDir%\..\8.1\lib\winv6.3\um\x86"

Building for UAP 10.0
---------------------

  FOR_WINRT=1 FOR_UAP=1

Using Microsoft Visual C++ 2015 (or later) is required.  When using the
above, something like the following macros will need to be added to the
NMAKE command line as well:

  "NSDKLIBPATH=%WindowsSdkDir%\..\10\lib\10.0.10586.0\um\x86"
  "PSDKLIBPATH=%WindowsSdkDir%\..\10\lib\10.0.10586.0\um\x86"
  "NUCRTLIBPATH=%UniversalCRTSdkDir%\..\10\lib\10.0.10586.0\ucrt\x86"

Building for the Windows 10 SDK
-------------------------------

  FOR_WIN10=1

Using Microsoft Visual C++ 2015 (or later) is required.  When using the
above, no other macros should be needed on the NMAKE command line.

Other preprocessor defines
--------------------------

Additionally, preprocessor defines may be specified by using the OPTS macro
on the NMAKE command line.  However, not all possible preprocessor defines
may be specified in this manner as some require the amalgamation to be built
with them enabled (see http://www.sqlite.org/compile.html). For example, the
following will work:

  "OPTS=-DSQLITE_ENABLE_STAT4=1 -DSQLITE_ENABLE_JSON1=1"

However, the following will not compile unless the amalgamation was built
with it enabled:

  "OPTS=-DSQLITE_ENABLE_UPDATE_DELETE_LIMIT=1"

This script is designed to create fts4/5 tables with more than one column.
The -colsize option should be set to a Tcl list of integer values, one for
each column in the table. Each value is the number of tokens that will be
inserted into the column value for each row. For example, setting the -colsize
option to "5 10" creates an FTS table with 2 columns, with roughly 5 and 10
tokens per row in each, respectively.

................................................................................
Each "FILE" argument should be a text file. The contents of these text files is
split on whitespace characters to form a list of tokens. The first N1 tokens
are used for the first column of the first row, where N1 is the first element
of the -colsize list. The next N2 are used for the second column of the first
row, and so on. Rows are added to the table until the entire list of tokens
is exhausted.

This script is designed to create fts4/5 tables with more than one column.
The -colsize option should be set to a Tcl list of integer values, one for
each column in the table. Each value is the number of tokens that will be
inserted into the column value for each row. For example, setting the -colsize
option to "5 10" creates an FTS table with 2 columns, with roughly 5 and 10
tokens per row in each, respectively.

................................................................................
Each "FILE" argument should be a text file. The contents of these text files is
split on whitespace characters to form a list of tokens. The first N1 tokens
are used for the first column of the first row, where N1 is the first element
of the -colsize list. The next N2 are used for the second column of the first
row, and so on. Rows are added to the table until the entire list of tokens
is exhausted.
