buffer_diff: Fix panic when staging hunks with stale buffer snapshot (#51641)
When the buffer is edited after the diff is computed but before staging,
anchor positions shift while diff_base_byte_range values don't. If the
primary (HEAD) hunk extends past the unstaged (index) hunk, an edit in
the extension region causes the overshoot calculation to produce an
index_end that exceeds index_text.len(), panicking in
rope::Cursor::suffix.

Fix by clamping index_end to index_text.len(). This is safe because the
computed index text is an optimistic approximation — the real staging
happens at the filesystem level via git add/git reset.

Closes ZED-5R2

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
