Copyright Attributions for RepoDB #1299

[mikependon]

Summary

Adds copyright attribution headers to every .cs file across all RepoDb solutions (source and tests), derived from git commit history rather than a blanket assumption.

Method

For each file, walked its full history with git log --follow (a single bulk history pass was tried first but discarded — this repo has 15+ structurally-similar provider packages, which makes git's content-similarity rename detection prone to false cross-project matches when run in bulk). Based on the earliest commit and the full set of contributors, each file got one of:

#region Copyright Attributions

// Copyright (c) 20XX Michael Camara Pendon.
// Licensed under the Apache License, Version 2.0.
// See the LICENSE file in the project root for full license information.

#endregion

• Solo — created and only ever touched by mikependon (as above).
• Co-authored — created by mikependon, later touched by others: adds // Portions copyright their respective RepoDB contributors.
• Created by another contributor: // Copyright (c) 20XX {Contributor} and Michael Camara Pendon.

Scope

• 2,530 .cs files repo-wide: RepoDb/RepoDb.Core, RepoDb.Extensions, every DB provider package, RepoDb.Benchmarks, and RepoDb.Telemetry.* — 1,510 solo, 943 co-authored, 77 created by another contributor (SergerGood, Bert Huijben, Tommaso Bertoni, fredliex, Mauro Cardillo, Paolo Bassi, orthoxerox, David Rothmann, Nabil Gardon, Rodel Dagumampan).
• 919 of those files — the newer provider packages (Oracle, ClickHouse, Db2, MariaDb, MariaDbConnector, Vertica, Firebird, EnterpriseDb, and their *.BulkOperations counterparts, plus MySql/MySqlConnector.BulkOperations) — were normalized to a single flat line, // Copyright (c) 2026 Michael Camara Pendon., regardless of co-authorship history.

Contributor breakdown

Of the files not covered by the 919-file flat-date normalization above, 685 still carry a "Portions copyright..." line (created by Michael, modified by someone else) and 75 were created entirely by another contributor. By contributor:

("Modified" counts a file once per contributor who touched it, so files with several contributors are counted more than once — 685 files produce 1,046 modification credits.)

Testing

Header-only change (comments), verified programmatically: every targeted file has exactly one attribution block, no duplicates, no gaps, and no other lines touched.
