2009-02-16 Yong Sun <yong.sun@sun.com>
	* src/LEMgr.{hh, cpp}:
	Fixed CR 6801571, iiimd sometime crashes in first gdm login.
	Added lock in LEMgr::initialize_ledata(), to avoid racing conditions.

2007-09-12 Osamu Sayama <osamu.sayama@sun.com>
	* src/{IMProtocol.hh,IMProtocol.cpp}
	Add lock for immap variable. Without this, immap variable was 
	modified by add_imstate [] when being accessed by remove_imstate() 
	erase(). Since immap map variable in IMProtocol is shared between 
	threads, immap must be updated with using an exclusive control.

2006-09-20 Osamu Sayama <osamu.sayama@sun.com>
	* src/{LE.cpp, LE.hh}
	Add lock for iml_if_context_ref_count variable.
	Without this, iml_if_context_ref_count is counted by two threads 
	if openif() is called by two threads at the almost same time. 
	So this variable must be locked before changing the value.

2006-06-14 Osamu Sayama <osamu.sayama@sun.com>
	* src/{IIIMP_IMState.hh,IIIMP_IMState.cpp}
	IIIMP_IMState::user_imstate_map is defined as static member
	variable in IIIMP_IMState so that this value is shared between threads.
	This means that the exclusive access control like lock must be used to 
	access this variable whenever it needs update, otherwise the state of
	user_imstate_map is broken. So added IMLock before using it.

2006-06-02 Osamu Sayama <osamu.sayama@sun.com>
	* src/IIIMP_ICState.cpp
	iiimd sometimes crash when switching language engine because
	uninitialized data is sometimes sent. Add initial value of
	preply.

2006-05-30 Osamu Sayama <osamu.sayama@sun.com>
	* src/{IMSvrArg.cpp,main.cpp,IMDesktop.cpp}
	Save parent pid when iiimd starts and use it instead of pid 1
	for checking whether SIGTERM should be called. This is
	because some system returns the values other than one.

2006-05-12 Osamu Sayama <osamu.sayama@sun.com>
	* src/{IIIMP_ICState.cpp,LEMgr.cpp,IMInputContext.cpp} :
	Add error check for LEContext creation error.
	If failed to create LEContext, remove it from lemap,
	otherwise, a server tries to reconnect whenever creating
	LEcontext and this causes performance problem.

2006-04-12 Yong Sun <yong.sun@sun.com>

	* src/IIIMP_ICState.cpp:
	Gcc thought "goto error" may jump out the initialization of following local variables:
	  IIIMP_string *pstrh = NULL, *pstr = NULL, *pcur = NULL, *pimname = NULL;
	  IIIMP_card32_list *pilist = NULL;
	So, move them up.

2006-04-11 Osamu Sayama <osamu.sayama@sun.com>
	* src/IIIMP_ICState.cpp : Since aux_event.toaux is sometimes
	not updated and this causes iiimd to be crashed, add the
	error check for send_event_getvalues().

2006-04-06 Osamu Sayama <osamu.sayama@sun.com>
	* src/{LE.cpp,IMDesktop.cpp,IMDesktop.hh} : Revised lock
	in LEContext::initialize() and LEContext::~LEContext().
	Without this, a broken iml_desktop is inserted at
	add_session_to_desktop() if an another thread calls
	release_iml_desktop() between request_iml_desktop() and 
	add_session_to_desktop().

2006-03-23 Osamu Sayama <osamu.sayama@sun.com>
	* src/{IMDesktop.cpp,LE.cpp,LE.hh} : When login/logout, 
	a few threads call request_iml_desktop/release_iml_desktop
	functions at the almost same time. However, there is no lock 
	mechanism, the problem like two iml_desktop is created or 
	iml_desktop is freed twice occurs and this causes iiimd crash. 
	So the lock is needed before handling these functions.

2006-03-07 Osamu Sayama <osamu.sayama@sun.com>
	* src/LEMgr.cpp: Add num pointer check for preq_imdesc->get_string()
	Without this, iiimd sometimes crash on DEBUG mode.

2005-02-02  Naoyuki Ishimura  <Naoyuki.Ishimura@Sun.COM>
	
	* src/IIIMP_IMState.cpp: send_hotkeys()
	fixed SEGV if curr_input_lang.get_chrstr() is NULL

	desktops (with same username, same hostname and different 
	display_id).

2005-04-22  Jens Petersen  <petersen@redhat.com>

	* sys/RedHat/iiimd: Define NAME for name of server, USER for
	user/group name and SOCKETDIR for unix socket directory and use them.
	Make sure USER owns SOCKETDIR and its contents to prevent iiimd
	not starting if for example root should own the unix domain socket.

	* lib/iml/SunIM.c
	* src/IIIMP_ICState.cpp
	* src/IIIMP_ICState.hh
	* src/IIIMP_IMState.cpp

	- Modified Server to use the new protocols (IM_FILE_OPERATION
	  and IM_FILE_OPERATION_REPLY). These two protocols will 
	  replace all the protocols previously added to support the 
	  namespace based I/O related operations.

	- Removed the namespace listener protocol related modifications.

2005-03-25  Sriram Swaminathan  <sriram.swaminathan@sun.com>

	* lib/iml/SunIM.c

	The namespace based I/O APIs were returing the wrong return
