It turns out that Busted started cleaning the environment in 2.0rc5 as a
result of Olivine-Labs/busted#62. This, in turn, caused the ffi module
to be reloaded for each spec file, and LuaJIT doesn't appreciate it.
The net effect is an assertion error in LuaJIT.
By using the --helper feature of Busted, we can pre-load some modules
ahead of Busted and prevent it from reloading them--making LuaJIT happy
again.
This is necessary for newer versions of Busted, otherwise assert will be
nil and the tests will die.
Note: this does not mean the tests now work with the latest Busted.
There are still several issues preventing that from happening.
It turns out the FreeBSD 10 VM has a symlink for the home directory to
/usr/home. Unfortunately, this breaks the test as arg[0] may not have
the symlink resolved, but the path returned from the exe() call will.
As a result, the comparison fails, even though the result is correct.
Let's fix this by running the absolute path through exe() too, and then
comparing the results.
The primitive C canonicalizer we use to strip out duplicate header
declarations and keep luajit's ffi happy, didn't work properly in this case.
What happened is this (in /usr/include/ctype.h):
__DARWIN_CTYPE_TOP_inline int
isspecial(int _c)
{
return (__istype(_c, _CTYPE_T));
}
Gets preprocessed to something like:
__inline int
isspecial(int _c)
{
return (__istype(_c, _CTYPE_T));
}
On OSX/gcc. The formatter wasn't recognizing this entire function as
something to put on a single line because it naively just checks for
"static" or "inline" for that, but not "__inline".
This error doesn't occur on OSX/clang. Without looking further into it, I
guess that __DARWIN_CTYPE_TOP_inline gets defined to inline on clang, but
__inline on gcc, for some reason.
This helps issue #1572 along.
The second argument to lfs.attributes() serves only to select a specific
part of the normally returned table. It's not a file open flag (e.g.: as for
fopen() in C). Also made the (n)eq checks a bit more idiomatic.
Fixes#1831
Add section `before_install` in `.travis.yml` to create test group and
add current user to this group.
It is needed because by default user on Travis-CI belongs only to one
primary group derived from that user. So we have no alternative to
change group of the file.
Move tests of path_full_dir_name to path_spec. It is only defined in path.h.
Not sure why this works most of the time (I can only trigger a failure when
running under lldb).
It's a more logical place to have the test as well.
