This TIP proposes the packages sqlite3 and tdbc::sqlite3 be re-distributed as part of the Tcl source code distribution.
Starting with the 8.6.* releases of Tcl, a collection of third party packages are being redistributed as part of the Tcl source code distribution under the directory tcl/pkgs/. This is partial fulfillment of the long-awaited batteries included vision for Tcl releases. The current collection of redistributed packages is Itcl TIP #50, Thread TIP #364, and tdbc TIP #308.
The sqlite3 package is perhaps the most striking example of a Tcl extension that has grown to eclipse Tcl itself. Created and maintained by TCT emeritus D. Richard Hipp, it should require little explanation here.
The tdbc::sqlite3 package provides the driver functionality to use the facilities provided by sqlite3 as the backend of tdbc operations. Created and maintained by Kevin Kenny of the TCT, it should also be familiar to Tcl insiders.
Adapt release operations as needed so that the latest releases of the sqlite3 and tdbc::sqlite3 packages are included in releases of Tcl 8.6.*.
Distribution of the tdbc package without any backend drivers has quite limited utility. Adding these two packages to the distributed set provides at least one fully working backend with no third-party dependencies. This permits testing and demonstrating the capabilities of tdbc everywhere it goes.
By including sqlite3 in the Tcl source code distribution, Tcl can take a place alongside PHP and Python on the list of famous users of SQLite . Since SQLite is now easily more broadly esteemed than Tcl itself, this can only help our public image.
The package tdbc::sqlite3 is itself written entirely in Tcl. Unlike the packages so far chosen for redistribution under tcl/pkgs/, it contains no C code. The tcl/pkgs/ harness and the TEA or tclconfig systems it descends from have so far not paid sufficient attention to this case. Including this package will force those systems over time to better support that common implementation case. This can only make package support tools better for more package authors. Also, as support for such packages under tcl/pkgs/ matures, the large collection of packages that have been distributed with Tcl on a more ad hoc basis, including tcltest, msgcat, http, platform, and platform::shell, may be able to migrate to new places under the tcl/pkgs/ framework. This may eventually lead to the ability to selectively take packages from tcllib for redistribution with Tcl.
