It turns out that CMake always canonicalizes `CMAKE_INSTALL_PREFIX` to
an absolute path--if it's a relative path, it canonicalizes it relative
to the build directory. As a result, the only thing the DESTDIR and
relative directory check prevents is an installation into the root
directory since CMake strips the trailing slash, turning "/" into an
empty string. Let's just remove the check all together, since it cannot
accomplish what we intended.
Commit a1d411f9c9 just assumes that gcc
will support the `-Og` option, but gcc that comes with Ubuntu 12.04 does
not. Let's check to see if the flag is supported, and then decide
whether to enable it or not.
It turns out that `file(INSTALL ...)` already accounts for `DESTDIR`, so
this wasn't creating the directory structure in the correct location.
Instead, we need to do our existence check with `DESTDIR`, but leave it
off when doing the install step.
While we're at it, add a check to make sure `ENV{DESTDIR}` is not being
used with a relative path, as that construct doesn't make much sense.
This fixes issue #1387 discovered while trying to make helptag
generation work correctly in #1381.
Unfortunately, we can't force the specific inclusion of a header file.
So if anything add /opt/local/include to the include path--such as
libintl--then other dependencies might be drawn from /opt/local at
compile time, even though we detected them elsewhere at configure time.
This, in turn, causes issues with mixed versions, such as the iconv.h
header being pulled from /opt/local/include, but linked against the
library in /usr/lib--which can be mismatched versions.
So, despite CMake's best effort to treat /sw and /opt/local as just
another system area, we really need to give them preferential treatment.
To do this, we add them to CMAKE_PREFIX_PATH.
This fixes an issue discovered while re-enabling iconv in #1370.
When building under Homebrew, we want to let Homebrew manage
downloading and extracting the tarballs. See PR #1411.
Also make sure to skip only if directory is not empty. Fix#1433.
Use save_tv_as_string(), same as vimL system(). This also makes
jobsend() more liberal in what it can accept. For example,
`jobsend(j, 123)` is now valid.
Closes#1176
Factor out string_to_list() from f_system()'s implementation
and use that to set job_data. This has the technical advantage of
preserving NULs, and may be more convenient for users.
Required for #1176.
The -O3 optimization level can often lead to dangerous (and sometimes
incorrect) optimizations being performed. So let's use a level that's
more stable.
During test setup, we used to call a vimscript function(BeforeEachTest) that
attempted to restore Nvim to it's initial state as much as possible in order to
provide a clean environment for running new tests. This approach has proven to
be unreliable, as some tests leave state that can affect other tests, eventually
causing failures that are difficult to debug.
This commit changes the 'clear' function so it will restart Nvim every time it
is called, which is a slower, but more reliable solution that will simplify
spotting bugs in the future.
Some other improvements/fixes were also performed:
- Whenever an error is detected in a handler passed to "run()", the event loop
will be stopped and the error will be propagated to the main thread.
- Errors and the "cleanup()" function will always send a quit command to the
current Nvim instance. This should prevent memory starvation when running
tests under valgrind(where each Nvim instance can consume a lot of memory).
- Fixed a wrong assertion in server_requests_spec.lua. Previously the failure
was undetected in a notification handler.
- Fixed some tests to expect fully clean registers. The deleted cleanup function
used to put an empty string in every register, but that resulted in a extra
line being added.
