When getting the properties of a DatePeriod instance we have to retain
the proper classes, and when restoring a DatePeriod instance we have to
cater to DateTimeImmutable instances as well.
The ext/date/lib is bundled library and also includes additional
timelib.m4 macros and checks specific for PHP.
All the checks in the timelib.m4 are already done in the PHP's
configure.ac:
- headers except for io.h and strings.h
- two functions checked strftime and gettimeofday
- if size of longint is 8
- if size of int is 4
- int32_t and uint32_t types using the PHP_CHECK_STDINT_TYPES
Macro `AC_TIMELIB_C_BIGENDIAN` defined in timelib.m4 is not used.
The two checkings for strtoll and atoll have been moved to date extension's
config0.m4 file.
Additional check for headers <io.h> and <strings.h> has been added to
config0.m4 of the date extension.
Therefore the timelib.m4 can be simplified and removed from the bundled
library to have easier maintenance in the later branches and also
upstream library.
get_properties() constructs these as fresh objects with no relation
to the internals, there is no need to clone them again. Additionally
the current implementation leaks memory, because the original objects
are never freed (see PR #3121).
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines in all
*.phpt sections.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.
