"Always use `find_package` with `REQUIRED`."
- We make an exception for LuaJit (not REQUIRED): the `nvim-test` target
is included only if we can find LuaJit.
This is partially a cargo-cult (reference below), but it uncovered at
least one problem: `find_package(LibIntl REQUIRED)` fails on my vanilla
ubuntu 16.04 system.

Prior to CMake 2.8.12, generator expressions could only be used in
custom commands so the path to libnvim-test in test/config/paths.lua was
set by inspecting the target's LOCATION property. Post 2.8.12, the
file(GENERATE) command exists to handle this, but it can't interpolate
normal CMake variables.
In order to bridge the gap while < 2.8.12 is supported, use
configure_file() to create paths.lua.gen with the
$<TARGET_FILE:nvim-test> generator expression and then generate the
final paths.lua file.
Closes#7077
New logging is guarded by cmake LOG_LIST_ACTIONS define. To make it more
efficient it is allocated as a linked list with chunks of length
2^(7+chunk_num); that uses basically the same idea as behind increasing kvec
length (make appending O(1) (amortized)), but reduces constant by not bothering
to move memory around what realloc() would surely do: it is not like we need
random access to log entries here to justify usage of a single continuous memory
block.
closes#7283
regression by 42d892913d
- Don't need to explicitly put "-O2 -g" in RelWithDebInfo; CMake does
that already. That was left-over from 42d892913d which removed the
"Dev" custom build-type, but repurposed the logic for RelWithDebInfo.
- `if(DEFINED MIN_LOG_LEVEL)` doesn't work.
- `if(${MIN_LOG_LEVEL} MATCHES "^$")` doesn't work if -DMIN_LOG_LEVEL is
omitted.
- `if(MIN_LOG_LEVEL)` also isn't what we want: it would be true if
MIN_LOG_LEVEL=0.
As of unibilium 1.2.1, directly manipulating unibi_var_t is deprecated.
../src/nvim/tui/tui.c: In function 'update_attrs':
../src/nvim/tui/tui.c:321:7: warning: 'i' is deprecated: use unibi_var_from_num or unibi_num_from_var instead [-Wdeprecated-declarations]
data->params[0].i = (fg >> 16) & 0xff; // red
^~~~
In file included from ../src/nvim/tui/tui.c:12:0:
/usr/include/unibilium.h:632:9: note: declared here
int i UNIBI_DEPRECATED("use unibi_var_from_num or unibi_num_from_var instead");
^
All use should go through unibi_{num,str}_from_var and
unibi_var_from_{num,str}. Wrap access of unibi_var_t behind a new
UNIBI_SET_NUM_VAR macro which uses the new functions when they're
available.
Handling of process exit is still broken. It detects the moment when the
child process exits, then quickly stops polling for process output. It
should continue polling for output until the agent has scraped all of the
process' output. This problem is easy to notice by running a command like
"dir && exit", but even typing "exit<ENTER>" can manifest the problem --
the "t" might not appear.
winpty's Cygwin adapter handles shutdown by waiting for the agent to close
the CONOUT pipe, which it does after it has scraped the child's last
output. AFAIK, neovim doesn't do anything interesting when winpty closes
the CONOUT pipe.
The main purpose of this build-type was to avoid unwanted ~/.nvimlog
files (which could get really big, and also affects performance) for
non-devs. But that is no longer necessary since the log system now
avoids non-critical logging by default (#6827).
This essentially reverts 87e5a41316
- Establish ERROR log level as "critical". Such errors are rare and will
be valuable when users encounter unusual circumstances.
- Set -DMIN_LOG_LEVEL=3 for release-type builds
Compile `nvim` executable against Lua if PREFER_LUA=ON.
As the testing library `nvim-test` requires LuaJIT, it is
still compiled against LuaJIT. If LuaJIT is not available,
`nvim-test` is not built.
For CI builds unibilium is provided through msys2 packages, and
libtermkey is built from source in third-party from equalsraf/libtermkey.
In Windows we cannot read terminal input from the stdin file descriptor,
instead use libuv's uv_tty API. It should handle key input and encoding.
The UI suspend is not implemented for Windows, because the
SIGSTP/SIGCONT do not exist in windows. Currently this is a NOOP.

Reasoning: luajit is not being compiled with sanitizers, lua is. Given that
linking with sanitized libraries requires sanitizers enabled, it is needed to
either compile libnvim-test with sanitizers or link it with lua compiled without
sanitizers. Most easy way to do the latter is just use luajit which is compiled
without sanitizers (as they do not work well with luajit).
No tests yet, no documentation update, no :lua* stuff, no vim module.
converter.c should also work with typval_T, not Object.
Known problem: luaeval("1", {}) results in
PANIC: unprotected error in call to Lua API (attempt to index a nil value)
Ref #3823
- Add support for TEST_FILE to the `oldtest` target, for consistency
with the busted/lua tests.
Caveat: with the busted/lua tests TEST_FILE takes a full path, whereas
for `oldtest` it must be "test_foo.res".
- Add support for NVIM_PRG, again so that all test-related targets are
consistent.
- Use consistent name for NVIM_PRG. But still need to support NVIM_PROG
for QuickBuild CI.
Note: The `oldtest` target is driven by the top-level Makefile, because
it requires a TTY. CMake 3.2 added a USES_TERMINAL flag to
add_custom_target(). But we support CMake 2.8...

API level is disconnected from NVIM version. The API metadata holds the
current API level, and the lowest backwards-compatible level supported
by this instance.
Release 0.1.6 is the first release that reports the Nvim version and API
level.
metadata['version'] = {
major: 0,
minor: 1,
patch: 6,
api_level: 1,
api_compatible: 0,
api_prerelease: false,
}
The API level may remain unchanged across Nvim releases if the API has
not changed.
When changing the API,
- set NVIM_API_PRERELEASE to true
- increment NVIM_API_LEVEL (at most once per Nvim version)
- adjust NVIM_API_LEVEL_COMPAT if backwards-compatibility was broken
api_level_0.mpack was generated from Nvim 0.1.5 with:

The API level may remain unchanged across Neovim releases if the API has
not changed.
When changing the API the CMake variable NVIM_API_PRERELEASE is set to
true, and NVIM_API_CURRENT/NVIM_API_COMPATIBILITY are incremented
accordingly.
The functional tests check the API table against fixtures of past
versions of Neovim. It compares all the functions in the old table with
the new one, it does ignore some metadata attributes that do not alter
the function signature or were removed since 0.1.5. Currently the only
fixture is 0.mpack, generated from Neovim 0.1.5 with nvim --api-info.
Since C leaves whether char is signed or unsigned up to the implementer,
there are different defaults on different architectures.
Forcing unsigned char for one of our CI builds should help catch these
issues moving forward.
In Windows Lua's os.tmpname() returns relative paths starting with \s,
prepend them with $TEMP to generate a valid path.
In OS X os.tmpname() returns paths in '/tmp' but they should be in
'/private/tmp'. We cannot use os_name() for platform detection because
some tests use tempname() before nvim is spawned, instead use one of the
following:
1. Set SYSTEM_NAME environment variable before calling the tests, it
is set from CMAKE_SYSTEM_NAME(i.e. uname -s or 'Windows')
2. Call uname -s
3. Assume windows

Otherwise, busted may run a different interpreter than the one we
detected, without the capabilities we expect. (For instance, we might
have detected the luajit interpreter, but busted might run the lua
interpreter, without the ffi module.)
The TUI can be enabled/disabled at build time with -DFEAT_TUI, default is ON for
UNIX, and OFF for non UNIX. When off, Neovim prints a message to stderr, along
with a list of the server endpoints.
By default Neovim searched a Luajit instalation and linked against
the luajit library.
In practice Neovim only requires luajit to run the unit tests. All other
targets only require lua and the correct lua modules. This commit:
1. Remove the strict dependency on Luajit
2. Makes the unittest target depend on the lua 'ffi' module.
If the module is not available the target is not enabled
and a message is displayed.
This is needed as long as we support cmake older than 2.8.12. When we
bump the minimum version to 2.8.12, we can use target_compile_options()
and add_compile_options() instead.

In 33bc332, version constraints were added to pkg_search_module(), but
that only affects the set of directories searched by

Once the header directory is found, parse the version from
version_master.h so it can be checked by the find_package() call in the
root CMakeLists.txt.
When using the Visual Studio generator don't use get_target_property for
custom command, because it returns unexpanded VS variables (e.g.
$(Configuration)) within the result as part of the LOCATION path.
The single case where this is a problem is for getting the output path for
nvim-test, instead we use a path here.
The Visual Studio cmake generator creates subdirectories inside
the build path for different build configuration. But this breaks some of our
cmake scripts, like the help tags installer, that assume the targets are
built in that location. Updated CMakeLists.txt to remove extra paths.

We use `git describe` to stamp pre-release versions (dev builds). But
`git describe` uses the result of the most-recent tag (the current
_release_ version)--so we must munge it with the _next_ (i.e.
unreleased) version.
Also fix non-git builds: do not invoke git_describe(NVIM_VERSION_MEDIUM)
if we're not in a git tree, else it gets the dummy value
"HEAD-HASH-NOTFOUND".
Example :version output in non-git build:
NVIM 0.1.2-dev
Example :version output in git build:
NVIM v0.1.2-176-g9c3c2b5
Without this compilation fails due to a missing symbol: SRWLOCK in libuv
headers. _WIN32_WINNT defines the Windows header version that is to be used,
and it seems libuv requires this version. See
b471b33da8
If nvim is built from a non-tagged commit, the truncated commit hash is
already appended to the main version string (e.g., "NVIM v0.1.0-83-g959f260 ..."),
making the "Commit:" field redundant.
Regarding the truncated hash length: we don't have nearly enough commits
to worry about collisions, and probably won't ever, so the default
length should be fine.
When building in a git repo:
- If HEAD corresponds to an annotated tag, (i.e. git_get_exact_tag()
returns truthy) the current build is considered a "release" build:
NVIM_VERSION_MEDIUM is directly assigned the tagged version name,
and NVIM_VERSION_* defines are ignored.
- If HEAD is not a tagged release, then NVIM_VERSION_MEDIUM is
directly assigned the result of `git describe`.
If git (or the repo) is not available:
- The NVIM_VERSION_* defines are used to define NVIM_VERSION_MEDIUM.
Sample outputs for `nvim --version` and `nvim +version`:

Before this change, building Neovim would recursively search parent
directories for a .git directory. If Neovim was downloaded as a tarball
(i.e. without a .git directory), but placed in a subdirectory of
a Git repository, this caused a CMake error. Such a situation could
occur when packaging Neovim, for example.
Unfortunately, the previous attempt in #3317 did not fix this problem.
* Hide commit information from --version if we can't find any (e.g. when
building from tarball).
To define a release in CMake, set NVIM_VERSION_PRERELEASE to "".
This will modify --version output to:
* Show annotated Git tag instead of commit hash (NVIM_VERSION_COMMIT).
* Hide commit date (NVIM_VERSION_BUILD).
Introduce new build type Dev that replaces RelWithDebInfo for development
builds off master and has optimizations, debug info, and logging enabled.
Keep assertions enabled for RelWithDebInfo.
If downloading Neovim as a tarball (i.e. without Git data),
building Neovim will search parent directories for a .git directory.
Explicitly set GIT_DIR to the project directory to avoid that.

The non-english manuals are completely outdated and still written in

seems to be that it won't, at least in the form of an executable
installed alongside `$(PREFIX)/bin/nvim` (see #2700).
In `nvim.1`, the argument to the `.Os` macro was removed. This was done
because its only purpose was to signify that nvim and nvimtutor
were part of the "Neovim" distribution, i.e., one and the same, which
isn't applicable anymore because `nvimtutor.1` is being removed.
From the `.Os` documentation in `man mdoc`:
Os
Operating system version for display in the page footer. This is the
mandatory third macro of any mdoc file. Its syntax is as follows:
.Os [system [version]]
The optional system parameter specifies the relevant operating system or
environment. It is suggested to leave it unspecified, in which case
mandoc(1) uses its -Ios argument or, if that isn't specified either,
sysname and release as returned by uname(3).
Examples:
.Os
.Os KTH/CSC/TCS
.Os BSD 4.3

When checking code with check_c_source_compiles, the "check variable"
(for the _FORTIFY_SOURCE detection: previously _FORTIFY_SOURCE_ACCEPTABLE, now
HAS_ACCEPTABLE_FORTIFY) is passed to the compiler like
-D_FORTIFY_SOURCE_ACCEPTABLE. This throws off hardening-wrapper [1],
which then NOT sets _FORTIFY_SOURCE=2 for the check, assuming it had already
been set manually as it detected -D_FORTIFY_SOURCE*. Renaming the "check
variable" to not match this pattern works around this problem.

Resolves#2632. This is done so C helper modules don't generate unexpected
coverage output.

For now, only install man pages matching "nvim*.1": we don't want to
install xxd.1 as it might conflict with that of a user's Vim
installation.

This will help make sure that we build all the right prereqs before
manually running tests under QuickBuild.
Notice that shell-test has been added as a prereq for the functional
tests, since it's a requirement for testing the terminal features.
Old behaviour: termopen('cmd') would run `&shell &shcf "cmd"`, which
caused the functional tests to fail on some systems due to the process
not "owning" the terminal. Also, it is inconsistent with jobstart().
Modify termopen() so that &shell is not invoked, but maintain the old
behaviour with :terminal. Factor the common code for building the
argument vector from jobstart() and modify the functional tests to call
termopen() instead of :terminal (fixes#2354).
Also:
* Add a 'name' option for termopen() so that `:terminal {cmd}` produces
a buffer named "term//{cwd}/{cmd}" and termopen() users can customize
the name.
* Update the documentation.
* Add functional tests for `:terminal` sinse its behaviour now differs
from termopen(). Add "test/functional/fixtures/shell-test.c" and move
"test/functional/job/tty-test.c" there, too.

* 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.
For built-in dependencies, shared libraries are removed and static
linking is always used.
For systemwide dependencies, static linking should not be used.
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.
Problem: With some regexp patterns the NFA engine uses many states and
becomes very slow. To the user it looks like Vim freezes.
Solution: When the number of states reaches a limit fall back to the old
engine. (Christian Brabandt)
