@bors r+ p=1000 It would be nice to get a tidy check that looks for the header in the future, but that doesn't need to be included in this PR. Thanks Mark! 🎉 |

Could've sworn I had tested these test failures... @bors r=pietroalbini |

@Mark-Simulacrum What was the motivation for this change? How does it bear on e.g. #25664? |
|
No bearing, to my knowledge. The code is still licensed as before (MIT/Apache), just is cleaner by skipping the ~10 lines of boilerplate code in every file. |
|
@Mark-Simulacrum: I agree about it looking cleaner. But I remember past discussion on GitHub where, if I recall correctly, Mozilla was said to have found the license header at the top of every source file legally necessary. What do you think about adding SPDX comments to every file instead? See https://spdx.org/sites/cpstandard/files/pages/files/using_spdx_license_list_short_identifiers.pdf . Within a project of mine, this was required. |
|
@Mark-Simulacrum, @pietroalbini, was there previous discussion of this change somewhere? Not that I’m opposed to it, but I’m curious of the arguments. Do the reasons these headers were added in the first place no longer hold? Why? |
|
@SimonSapin the discussion was in #43498. |
The Rust project determined these were unnecessary a while back[1,2,3] and we follow suite. [1] - rust-lang/rust@0565653 [2] - rust-lang/rust#43498 [3] - rust-lang/rust#57108
This performs the relicensing to MIT/Apache-2.0 as discussed in tiny-http#161 (archived link: http://web.archive.org/web/20191009143715/https://github.com/tiny-http/tiny-http/issues/161) Instead of updating the file headers, I just removed them, as the rustc compiler has done the same: rust-lang/rust#57108
Everything is replaced by a more explicit message in the COPYRIGHT file. Inspired by rust-lang/rust#43498 and rust-lang/rust#57108.

Dual-licensing the project under either the MIT or Apache 2.0 licenses provides for maximum compatibility within the Rust ecosystem and is recommended by the upstream API guidelines. The Rust project no longer feels that per-file license headers are required, but it's widely debated elsewhere. To simplify those headers, I'll follow the lead of the Linux kernel project and utilize the Software Package Data Exchange (SPDX) short-form identifiers. Copyrights in the project are retained by their contributors and no copyright assignment is required to contribute. Authorship information can be found in the version control history.

The license was removed from `binary_heap.rs` in rust-lang/rust#57108 after it was determined that the per-file license headers were not necessary. See also discussion in rust-lang/rust PRs #53654, #53617, and #43498.
These were all removed a while ago in rust-lang/rust#57108
This pull request removes the header licenses from files across the Rust repository.
I've attempted to check for any remaining headers and removed all of them -- any we've missed can be removed in the future; there's nothing blocking that.
Unfortunately, not all of the changes are as basic as "removing a header" because some of them required test file updates or otherwise. However, I am fairly confident that the changes in this pull request, while wide-sweeping, are unlikely to actually make any tests fail to properly test the code; any non-script based changes were manual and carefully verified.
