- HAVE_RANDOM is not checked at all.
- HAVE_STRERROR is not checked in code built using the defines from the main
configure.
- HAVE_LCHOWN is only checked in nsinstall.c, which means the test is also wrong
since it's checking for the target instead of the host. Also, lchown is only
used of the -o and -g options of nsinstall, which, as far as I know, we don't
use (and if we were, that would fail with nsinstall.py, which explicitly rejects
them).
- HAVE_FCHMOD is only checked in nsinstall.c, so same as above about the
correctness of the check. If it's not available, nsinstall.c falls back to
chmod, which is fine enough for our use.
- HAVE_SNPRINTF is not checked.
- HAVE_MEMMOVE is checked in parser/expat/lib/xmlparse.c, but it's also
unconditionally defined in expat_config.h which is included from that file.
- HAVE_SETBUF is checked in a couple files, but setbuf is C89 and C99, I think
it's safe to assume all compilers we support are C89 and C99. Interestingly,
windows does have it, but since we skip this check on windows, we don't use it.
- HAVE_ISATTY, same as HAVE_SETBUF, except it's POSIX instead of C89/C99.
- HAVE_FLOCKFILE is not checked at all.
- HAVE_STRTOK_R is not checked.
- HAVE_FT_SELECT_SIZE is not checked.
- HAVE_DLADDR is not checked under js/src.
- HAVE_GETPAGESIZE is not checked under js/src (it is in libffi, but ffi uses
its own configure)
- HAVE_LSTAT64, HAVE_STAT64, HAVE_STATVFS, HAVE_STATVFS64, HAVE_TRUNCATE64 are
not checked under js/src.
- HAVE_SBRK is not checked under js/src. Moreover,
js/src/assembler/wtf/Platform.h defines it depending on the platform.
- HAVE_SNPRINTF is not checked under js/src.
- HAVE_HYPOT is not checked under js/src.
- HAVE__UNWIND_BACKTRACE is not checked under js/src.
UnixSocketImpl, which mostly runs on the I/O thread, doesn't control
its reference to UnixSocketConsumer. If the connection status is
stored in UnixSocketConsumer, the I/O thread can't read it safely.
This patch duplicates the connection status in UnixSocketImpl, where
reading from the I/O thread is safe. Methods of UnixSocketImpl don't
need to access mConsumer any longer to obtain the connection status.
This is where the magic starts to happen. We move includes from the base
protocol header (${NAME}.h) to the parent and child headers (${NAME}Parent.h
and ${NAME}Child.h) to follow good include hygiene.
For the base protocol header, we examine the set of types used by struct and
union definitions to determine which headers we need to include.
For parent and child headers, we forward declare what we can and include
appropriate headers otherwise. For forward-declared types, we include the
appropriate headers in the parent and child source files.
When computing what set of includes a header file needs, we need to know
about all types that protocol-defined types use, not just qualified
ones: both global-scope names and same-namespace-as-protocol names are
valid to use without any sort of qualification. This flag would normally
not be used in generating actual C++ code and therefore defaults to False.
