Problem:
Coverity reports use after free:
*** CID 352784: Memory - illegal accesses (USE_AFTER_FREE)
/src/nvim/buffer.c: 1508 in set_curbuf()
1502 if (old_tw != curbuf->b_p_tw) {
1503 check_colorcolumn(curwin);
1504 }
1505 }
1506
1507 if (bufref_valid(&prevbufref) && prevbuf->terminal != NULL) {
>>> CID 352784: Memory - illegal accesses (USE_AFTER_FREE)
>>> Calling "terminal_check_size" dereferences freed pointer "prevbuf->terminal".
1508 terminal_check_size(prevbuf->terminal);
1509 }
1510 }
1511
1512 /// Enter a new current buffer.
1513 /// Old curbuf must have been abandoned already! This also means "curbuf" may
Solution:
Change terminal_destroy and terminal_close to set caller storage to NULL,
similar to XFREE_CLEAR. This aligns with the pattern found already in:
terminal_destroy

Neovim is a project that seeks to aggressively refactor Vim in order to:
- Simplify maintenance and encourage contributions
- Split the work between multiple developers
- Enable advanced UIs without modifications to the core
- Maximize extensibility
See the Introduction wiki page and Roadmap for more information.
Features
- Modern GUIs
- API access from any language including C/C++, C#, Clojure, D, Elixir, Go, Haskell, Java, JavaScript/Node.js, Julia, Lisp, Lua, Perl, Python, Racket, Ruby, Rust
- Embedded, scriptable terminal emulator
- Asynchronous job control
- Shared data (shada) among multiple editor instances
- XDG base directories support
- Compatible with most Vim plugins, including Ruby and Python plugins
See :help nvim-features for the full list!
Install from package
Pre-built packages for Windows, macOS, and Linux are found on the Releases page.
Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Void Linux, Gentoo, and more!
Install from source
See the Building Neovim wiki page for details.
The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
CMake hints for inspecting the build:
cmake --build build --target helplists all build targets.build/CMakeCache.txt(orcmake -LAH build/) contains the resolved values of all CMake variables.build/compile_commands.jsonshows the full compiler invocations for each translation unit.
Transitioning from Vim
See :help nvim-from-vim for instructions.
