2020-06-07 drh Fix minor OOM problems.
2020-06-07 drh AggInfo objects might be referenced even after the sqlite3Select() function that created them has exited.  So AggInfo cannot be a stack variable.  And it must not be freed until the Parse object is destroyed.
2020-06-07 drh Alternative fix to ticket [c8d3b9f0a750a529]:  Prior to deleting or modifying an Expr not that is referenced by an AggInfo, modify the AggInfo to get its own copy of the original Expr.

2020-06-05 drh Always use ?...? to indicate optional arguments in the output of ".help" in the CLI.  Change ".mode column" so that it automatically activates ".headers on" if headers have not been previously turned on or off.
2020-06-04 drh Add support for "box" mode in the CLI:  Like "table" except that it uses unicode box-drawing characters instead of ascii-art.
2020-06-04 drh Improved display of ".mode table" output for empty result sets.
2020-06-04 dan Use __has_extension(c_atomic) instead of __has_feature(c_atomic) to detect support for atomic load and store operations with clang.

2020-05-30 drh Draw the dashes below the headers in "explain" mode in the CLI.
2020-05-30 drh Improved VDBE comments on the ANALYZE code generator.  This change also fixes a harmless use of an uninitialized integer variable as an input to the %d format on a VDBE comment.

2020-05-29 drh Fix a memory leak in the CLI when an unknown or unrecognized argument is given to the ".dump" command.
2020-05-29 drh Improvements to columnar output in the CLI.  Columns automatically expand to contain the largest row.
2020-05-29 drh Space to hold the ".width" of columns in the CLI is now obtained from malloc() and hence is not limited in the number of columns supported.
2020-05-29 drh Incremental improvements to tabular output modes in the CLI.  The "markdown" and "table" modes no have headers turned on by default.
2020-05-29 dan Expand upon a comment in os_unix.c. No changes to code.
2020-05-29 drh In the json output mode of the CLI, do correct quoting of escape characters. Also, show BLOBs as JSON strings, possibly with embedded \u0000 bytes.
2020-05-28 drh Progress toward adding new output modes to the CLI:  json, table, and markdown.
2020-05-28 drh Enhance the ".quote" mode in the shell so that it honors .separator.
2020-05-28 drh When the sqlite_stat1 data is missing for some indexes of a table but is present for the table itself or for other indexes in the same table, then do not let the estimated number of rows in that table get too small, as doing so can deceive the query planner into ignoring a perfectly good index.
2020-05-27 drh Small performance improvement and size reduction in the expression code generator.
2020-05-27 drh Change a datatype from i16 to int to appease Converity and help eliminate a false-positive.

This is the top folder for Chromium's SQLite. The actual SQLite source is not in this repository, but instead cloned into the src directory from

The directory structure is as follows. Files common to all third_party projects (BUILD.GN, OWNERS, LICENSE) are omitted.

  • src/ The Chromium fork of SQLite (cloned via top level DEPS file).
  • scripts/ Scripts that generate the files in the amalgamations in src/.
  • sqlite.h The header used by the rest of Chromium to include SQLite. This forwards to src/amalgamation/sqlite3.h
  • fuzz/ Google OSS-Fuzz (ClusterFuzz) testing for Chromium's SQLite build This directory contains:

The SQLite amalgamation is committed to the SQLite Chromium repository (in src), but it is created by a script that lives in the Chromium repository. This is because the configuration variables for building and amalgamation generation are shared.

There are two amalgamations. The one in //third_party/sqlite/src/amalgamation is used by Chromium. A second, located at //third_party/sqlite/src/amalgamation_dev is used for some Chromium developer tools and is not distributed.

Upgrade to a new SQLite release.

Note SQLite tags all releases version-<release number>, e.g. version-3.33.0. The Chromium project prefixes all tags/branches with “chromium-”, e.g. chromium-version-3.33.0.

  1. Create new release branch

    Use the SQLite commit ID when creating a branch. For example “562fd18b9dc27216191c0a6477bba9b175f7f0d2” corresponds to the 3.33.0 release. The commit is used, instead of the tag name, because we do not mirror the SQLite tags along with the commits. The correct commit ID can be found at sqlite/releases.

    Create the branch at Gerrit/branches.

  2. Checkout the new Chromium release branch.

    cd //third_party/sqlite/src
    git fetch origin
    export VERSION=3.33.0
    git checkout -b chromium-version-$VERSION \
        --track origin/chromum-version-$VERSION
  3. Generate and commit the SQLite amalgamations.

    git add amalgamation
    git add amalgamation_dev
    git commit -m "Amalgamations for release $VERSION"
  4. Run local tests.

    Follow steps in Running Tests below to execute all verifications and tests.

  5. Upload the new release branch for review.

    git cl upload
  6. Roll the Chromium DEPS file.

    Once review above has merged:

    1. Roll the chromium/src/DEPS file to reference that new commit ID.
      roll-dep src/third_party/sqlite/src --roll-to <git hash of merged CL>
    2. Update the version in //third_party/sqlite/README.chromium. Append the commit created by roll-dep above.

Cherry-pick unreleased commit from SQLite.

Sometimes critical fixes land in SQLite's master, but are not yet in a release. If these need to be brought into the current release branch do the following:

  1. Checkout the current release branch.

    export VERSION=3.33.0
    cd //third_party/sqlite/src
    git checkout -b chromium-version-$VERSION \
      --track origin/chromium-version-$VERSION
  2. Cherry-pick the change

    Git can be used to cherry pick upstream changes into a release branch but the script is preferred. This script automates a few tasks such as:

    • Identifying the correct Git commit ID to use if given the Fossil commit ID.
    • Automatically calculating Fossil manifest hashes.
    • Skipping conflicted binary files.
    • Generating the amalgamations.

    Cherry-pick the commit:

    ../scripts/ <full git or fossil commit id>

    If there is a conflict that the script cannot resolve then, like git-cherry-pick, the script will exit and leave you to resolve the conflicts. Once resolved run the script a second time:

    ../scripts/ --continue
  3. Run local tests.

    Follow steps in Running Tests below to execute all verifications and tests.

  4. Upload cherry-picked change (with amalgamations) for review.

    git cl upload
  5. Update the Chromium DEPS file.

    Once review above has merged, roll the chromium/src/DEPS file to reference that new commit ID.

    roll-dep src/third_party/sqlite/src --roll-to <git hash of merged CL>

Running Tests

Build all desktop targets:

Check that added “chrome_” to all exported symbols. Only “_fini” and “_init” should be unprefixed, but are conditionally exported by the linker and may be omitted.

autoninja -C out/Default
nm -B out/Default/ | cut -c 18- | sort | grep '^T'

Running unit tests


Running web tests

third_party/blink/tools/ -t Default storage/websql/

Running SQLite's TCL test suite within the Chromium checkout.

This is one of the SQLite test suites. They take approximately 3 minutes to build and run on a fast workstation.

cd //third_party/sqlite
./scripts/ --testing
make --directory=src test | tee /tmp/test.log

Note: Tests may fail on Chromium release branches. This is because some tests rely on SQLite databases (binary files) which are committed to the source and are likely not merged down when cherry picked. It is safe to ignore these errors which should be reasonably easy to identify based on the cherry picked upstream changes.

Show error'ed tests:

egrep 'errors out of' /tmp/test.log

Show broken tests:

egrep 'Failures on these tests:' /tmp/test.log

Broken tests will also show lines ending in “...” instead of “... Ok”.

When done cleanup the SQLite repository:

cd src
make clean
git clean -i  # and delete everything
rm -rf testdir
git checkout amalgamation/sqlite3.c
git checkout amalgamation_dev/sqlite3.c
