The reference manual says that filename:join(A,B) is equivalent to
filename:join([A,B]). In some rare cases this turns out not to be
true:
1> filename:join("/a/.","b").
"/a/./b"
2> filename:join(["/a/.","b"]).
"/a/b"
In general, filename:join/1,2 removes single dots from the resulting
path, except dots that occur at the beginning or end of the path. The
problem above occurs when the first argument to join/2 ends with a
dot, then it is not removed even if the second argument differs from
an empty string and thus the dot ends up in "the middle" of the path.
This commit corrects this problem. A single dot is now only kept if it
occurs at the very beginning or the very end of the resulting path.
Test of filename:join/1,2 are added in filename_SUITE. In addition,
filelib_SUITE is updated with more tests of filelib:wildcard/2 since
this failed when the given current directory (second argument) ended
with a dot.

This commit complements 769996c0cd4cb68c157e39de725642f209ed7423 and
adds tests for the following problems introduced by
f11aabdc9fec593c31e6c4f3fa25c1707e9c35df:
Given the symlink 'dirlink' pointing to an existing dir, then
- filelib:is_regular("dirlink") -> false
- filelib:is_dir("dirlink") -> false
Given the symlink 'filelink' pointing to an existing file, then
- filelib:is_regular("filelink") -> false
- filelib:is_file("filelink") -> false
- filelib:last_modified("filelink") and filelib:filesize("filelink")
return the info of the link and not the file
Given the symlink "broken_symlink" pointing to a non-existing file, then
- filelib:wildcard("broken_symlink",File) -> []

This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where
filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never
follow symlinks. This fixed wildcard/1 but broke every other function using
eval_read_file_info/2.

This is a partial revert of 05c4d31b2c5c5f6ade7d91b55c598fe7fa58e509 in
which a new macro `?STR()` was introduced. This macro shouldn't be used in
scan_number/6 and scan_based_int/6 because the length of the string is
needed when computing column numbers through tok3/8.

This function now uses proc_lib:stop, which guarantees that the
process is terminated before the function return.
|
|
The functions utilize proc_lib:stop, which in turn utilizes
sys:terminate.
|
|
The new function utilizes sys:terminate.
|
|
This is to be used when implementing synchronous stop of generic
behaviours and other 'sys special processes'.

Values for which the precision or field width were too small in io_lib_format
could trigger an infinite loop or crash in term/5.

The POSIX standard for tar says that there must be at least
two 512-bytes zero blocks at the end of the tar archive file.
Our implementation would only emit a single 512-byte zero block if the
size of the last file was in the range 18*512 through 19*512-1 (modulo
20*512). GNU tar would correctly unpack such tar archive file, but
would emit a warning:
tar: A lone zero block at 20

This code was related to an old implementation of sys:get_state and
sys:replace_state. sys_sp2.erl is now more like sys_sp1.erl - in order
to avoid confusion.

When redefining and exporting the type map() erl_lint erroneously
