cygwin : ChangeLog dcrt0.cc mount.cc ntdll.h shared.cc
shared_info.h spinlock.h syscalls.cc
Log message:
* shared_info.h (user_info): Add dll_crt0_1 as a friend.
(user_info::version): Make LONG to accommodate spinlock use.
(user_info::create): New static function renamed from user_info_create.
(user_info::initialize): New private function renamed from
user_info_initialize.
(SHARED_VERSION): Delete.
(SHARED_VERSION_MAGIC): Ditto.
(USER_VERSION_MAGIC): Ditto.
(SHARED_INFO_CB): Ditto.
(USER_VERSION): Ditto.
(USER_VERSION_MAGIC): Ditto.
(CURR_SHARED_MAGIC): Update.
(CURR_USER_MAGIC): Ditto.
(shared_info::version): Make LONG to accommodate spinlock use.
(shared_info::create): New static function mirroring user_info::create.
(dll_crt0_1): Accommodate change to user_info::initialize.
* spinlock.h (spinlock::setto): New variable member.
(spinlock::done): New function.
(spinlock::spinlock): Generalize to allow arbitrary values and
timeouts. Call
done() when lock is not needed.
* ntdll.h: Make multiple-inclusion safe.
(NtQuerySystemTime): Declare.
* shared.cc (installation_root_inited): Rename from shared_mem_inited.
(init_installation_root): Make inline. Use a spinlock to ensure that
this is
initialized only once per session.
(user_info::initialize): Rename from user_shared_initialize. Protect
with
spinlock on sversion and remove other spinlock-like things. Remove
reference
to user_shared since it is now implicit. Refer to spinlock version of
multiple_cygwin_problem to ensure that any spinlock is released.
(user_info::create): Rename from user_shared_create. Accommodate
change from
user_shared_initialize to user_info::initialize.
(shared_info::create): New inline function.
(shared_info::initialize): Protect with spinlock on sversion. Move
heap_init
back under specific control of shared_info spinlock. Remove reference
to
SHARED_INFO_CB and just use sizeof(*this).
(memory_init): Move all locking into respective functions where it is
needed.
Accommodate name changes. Remove call to heap_init().
* syscalls.cc (seteuid32): Accommodate name change to
user_info::create().
* mount.cc (mount_info::create_root_entry): Report on errors from
add_item
since they should be nonexistent.
(mount_info::init): Don't initialize nmounts. It should already be
zero. Give
more verbose error when root_idx < 0. Implicitly use this pointer
rather than
explicitly referencing mount_table->.
(mount_info::add_item): Minor whitespace fix.
