+This directory contains components use to build an autoconf-ready package
+of the SQLite amalgamation:  sqlite-autoconf-30XXXXXX.tar.gz

-This file describes how to use the files in this directory to create a new
-version of the "autoconf-amalgamation" package.
-
-1. The following files should have executable permission:
-
-  chmod 755 install-sh 
-  chmod 755 missing 
-  chmod 755 depcomp
-  chmod 755 config.sub
-  chmod 755 config.guess
-
-2. Copy new versions of the following SQLite files into this directory:
-
-  sqlite3.c
-  sqlite3.h
-  sqlite3ext.h
-  sqlite3.1
-  sqlite3.pc.in
-  shell.c
-
-3. Update the SQLite version number in the AC_INIT macro in file 
-   configure.ac:
-
-     AC_INIT(sqlite, 3.6.3, http://www.sqlite.org)
-
-4. Run the following commands to push the version number change through
-   to the generated files.
-
-  aclocal
-  autoconf
-  automake
-
-5. Create the tclsqlite3.c file in the tea/generic directory. As follows:
-
-  mkdir -p tea/generic
-  echo "#ifdef USE_SYSTEM_SQLITE"      > tea/generic/tclsqlite3.c 
-  echo "# include <sqlite3.h>"        >> tea/generic/tclsqlite3.c
-  echo "#else"                        >> tea/generic/tclsqlite3.c
-  echo "#include \"../../sqlite3.c\"" >> tea/generic/tclsqlite3.c
-  echo "#endif"                       >> tea/generic/tclsqlite3.c
-  cat  ../src/tclsqlite.c             >> tea/generic/tclsqlite3.c
-
-6. Update the SQLite version in the AC_INIT macro in file tea/configure.in:
-
-  AC_INIT([sqlite], [3.6.3])
-
-7. From the 'tea' directory, run the following commands:
-
-  autoconf
-  rm -rf autom4te.cache
-
-8. Run "./configure && make dist". This builds a distribution package
-   named something like "sqlite-3.6.3.tar.gz". Rename to 
-   "sqlite-amalgamation-3.6.3.tar.gz" and use.
+To build the autoconf amalgamation, run from the top-level:

+   ./configure
+   make amalgamation-tarball

+The amalgamation-tarball target (also available in "main.mk") runs the
+script tool/mkautoconfamal.sh which does the work.  Refer to that script
+for details.

drh	59b1b58b66	There are asserts in place now that will prevent a recurrence of ticket [f97c4637102a3ae7]. Nevertheless, it is good to add some test cases as well. FossilOrigin-Name: e02959b9a0e1bacdd3939548d4434c042aacc2e6	2015-01-19 21:10:53 +00:00

drh	e1bb802c54	An alternative way of implementing the assert() that verifies the relative values of KeyInfo.nField+KeyInfo.nXField and the number of columns in a record. This version of the assert() only fires when the high-speed comparison routines are used - which is to say it only fires when the constraint actually matters.

(3) Update the README.first file in autoconf/ (4) The TOP macro in Makefile.in is now an absolute rather than a relative path.
