* Set JEMALLOC_NO_DEMANGLE to be able to use `je_*` functions,
regardless of how jemalloc was compiled (--with-jemalloc-prefix)
* Show jemalloc information in Neovim's version output.
Resolve#2449.
Jemalloc will be used if the cmake option `USE_JEMALLOC` is enabled(which is the
default). To avoid trouble with clang's ASAN, it is disabled by default if the
`SANITIZE` option is enabled.
Since jemalloc has thread cache for small objects, it fills the gap created by
removing klib memory pools.
The `xstrdup` funciton(memory.c) had to be reimplemented on top of `xmalloc` to
make it work with a custom allocator.
We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
- Removed term.c, term.h and term_defs.h
- Tests for T_* values were removed. screen.c was simplified as a
consequence(the best strategy for drawing is implemented in the UI layer)
- Redraw functions now call ui.c functions directly. Updates are flushed with
`ui_flush()`
- Removed all termcap options(they now return empty strings for compatibility)
- &term/&ttybuiltin options return a constant value(nvim)
- &t_Co is still available, but it mirrors t_colors directly
- Remove cursor tracking from screen.c and the `screen_start` function. Now the
UI is expected to maintain cursor state across any call, and reset it when
resized.
- Remove unused code
Problem: In some situations, when setting up an environment to trigger an
autocommand, the environment is not properly restored.
Solution: Check the return value of switch_win() and call restore_win()
always. (Daniel Hahler)

Regarding dict_lookup() in eval.c: both definitions are the same, the
only difference being the spacing between the indirection operator and
the indentation level.
`try_malloc` was changed in 8bb2c2c074 to
avoid a warning when size is 0. Then, this improves some things on that:
- Use local vars instead of changing parameters.
- Homogenize style for other related functions.
Problem : Undefined allocation of 0 bytes (CERT MEM04-C; CWE-131)
@ 148.
Diagnostic : Cautionary warning.
Rationale : Reported circumstance (calling calloc with requesting 0
size allocation) can occur, and it's not an issue. It's
perfectly legal doing so, though result is implementation
dependant. A given implementation can return NULL or a
valid pointer, so that free() can be called on it later the
same as if it was a real pointer. Such a pointer should not
be dereferenced, though.
Now, for some reason I can't explain, compiler is warning
us in the case of calloc, but not in the case of malloc,
which is doing the same.
Resolution : Refactor memory functions to avoid using implementation
dependant behaviour.
Proposed code is neater to read, and it avoids calling
system memory functions with size 0, thus behaving the same
everywhere.
Note that semantics for xmalloc/xcalloc is slightly
changed:
- Previously, an implementation that returns a valid
pointer on malloc/calloc with 0 size, would return that
pointer to xmalloc/xcalloc caller.
- Currently, a regular pointer is always returned.
They're unnecessary for the rest of the file, and they're only there at
all to help implement `free_all_mem` for use with Clang's Address
Sanitizer. So let's move them to avoid any confusion about why they are
there.
`-Wstrict-prototypes` warn if a function is declared or defined without
specifying the argument types.
This warning disallow function prototypes with empty parameter list.
In C, a function declared with an empty parameter list accepts an
arbitrary number of arguments when being called. This is for historic
reasons; originally, C functions didn't have prototypes, as C evolved
from B, a typeless language. When prototypes were added, the original
typeless declarations were left in the language for backwards
compatibility.
Instead we should provide `void` in argument list to state
that function doesn't have arguments.
Also this warning disallow declaring type of the parameters after the
parentheses because Neovim header generator produce no declarations for
old-stlyle prototypes: it expects to find `{` after prototype.
- The 'stripdecls.py' script replaces declarations in all headers by includes to
generated headers.
`ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'`
was used for this.
- Add and integrate gendeclarations.lua into the build system to generate the
required includes.
- Add -Wno-unused-function
- Made a bunch of old-style definitions ANSI
This adds a requirement: all type and structure definitions must be present
before INCLUDE_GENERATED_DECLARATIONS-protected include.
Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is
the only exception.
Less "blow a hole in your foot" than strncpy. As also indicated by coverity.
Implementation inspired by the linux kernel (very similar to OSX's Libc
implementation as well).
As discussed in #694, vim encryption uses old,
obsolete algorithms that are poorly implemented.
Since insecure cryptography is worse than no
cryptgraphy, the community voted in favor of
removing all crypto.
Various alternatives to the old crypto is
being discussed in #701.
Closes#694.
Move files from src/ to src/nvim/.
- src/nvim/ becomes the new root dir for nvim executable sources.
- src/libnvim/ is planned to become root dir of the neovim library.
