## Verifying Code Authenticity

If you obtained an SQLite source tree from a secondary source, such as a
GitHub mirror, and you want to verify that it has not been altered, there
are a couple of ways to do that.

If you have a release version of SQLite, and you are using the
`sqlite3.c` amalgamation, then SHA3-256 hashes for the amalgamation are
available in the [change log](https://www.sqlite.org/changes.html) on
the official website.  After building the `sqlite3.c` file, you can check
that it is authentic by comparing the hash.  This does not ensure that the
test scripts are unaltered, but it does validate the deliverable part of
the code and the verification process only involves computing and
comparing a single hash.

For versions other than an official release, or if you are building the
`sqlite3.c` amalgamation using non-standard build options, the verification
process is a little more involved.  The `manifest` file at the root directory
of the source tree
contains either a SHA3-256 hash (for newer files) or a SHA1 hash (for 
older files) for every source file in the repository.  You can write a script
to extracts hashes from `manifest` and verifies the hashes against the 
corresponding files in the source tree.  The SHA3-256 hash of the `manifest`
file itself is the official name of the version of the source tree that you
have.  The `manifest.uuid` file should contain the SHA3-256 hash of the
`manifest` file.  If all of the above hash comparisons are correct, then
you can be confident that your source tree is authentic and unadulterated.

The format of the `manifest` file should be mostly self-explanatory, but
if you want details, they are available
[here](https://fossil-scm.org/fossil/doc/trunk/www/fileformat.wiki#manifest).

# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support.  The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.

# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.

#***********************************************************************
#
# This file implements a program that produces scripts (either shell scripts
# or batch files) to implement a particular test that is part of the SQLite
# release testing procedure. For example, to run veryquick.test with a 
# specified set of -D compiler switches.
#
# A "configuration" is a set of options passed to [./configure] and [make]
# to build the SQLite library in a particular fashion. A "platform" is a
# list of tests; most platforms are named after the hardware/OS platform
# that the tests will be run on as part of the release procedure. Each 
# "test" is a combination of a configuration and a makefile target (e.g.
# "fulltest"). The program may be invoked as follows:
#
set USAGE {
$argv0 platforms
    List available platforms.

$argv0 tests ?-nodebug? PLATFORM
    List tests in a specified platform. If the -nodebug switch is 
    specified, synthetic debug/ndebug configurations are omitted. Each
    test is a combination of a configuration and a makefile target.

$argv0 script ?-msvc? CONFIGURATION TARGET
    Given a configuration and make target, return a bash (or, if -msvc
    is specified, batch) script to execute the test. The first argument
    passed to the script must be a directory containing SQLite source code.

$argv0 configurations
    List available configurations.
}

# Omit comments (text between # and \n) in a long multi-line string.

# This is a test case from content taken "from the wild".  In this
# particular instance, the query was provided with permission by
# Elan Feingold on 2013-06-27.  His message on the SQLite mailing list
# on that date reads:
#
#------------------------------------------------------------------------------
# > Can you send (1) the schema (2) the query that is giving problems, and (3)
# > the content of the sqlite_stat1 table after you have run ANALYZE?   If you
# > can combine all of the above into a script, that would be great!
# >
# > If you send (1..3) above and you give us written permission to include the
# > query in our test suite, that would be off-the-chain terrific.
#
# Please find items 1..3 in this file: http://www.plexapp.com/elan/sqlite_bug.txt
# 
# You have our permission to include the query in your test suite.
# 
# Thanks for an amazing product.
#-----------------------------------------------------------------------------
#
# This test case merely creates the schema and populates SQLITE_STAT1 and
# SQLITE_STAT3 then runs an EXPLAIN QUERY PLAN to ensure that the right plan
# is discovered.  This test case may need to be adjusted for future revisions
# of the query planner manage to select a better query plan.  The query plan
# shown here is known to be very fast with the original data.
#
# This test should work the same with and without SQLITE_ENABLE_STAT3

# https://www.sqlite.org/src/info/1be72aab9) introduced a new problem
# if the LHS of a BETWEEN operator is a WINDOW function.  The problem
# was found by (the recently enhanced) dbsqlfuzz.
