field. (class lockf_t): Add lf_ver field. (lockf_t::lockf_t): Initialize lf_ver to 0. (class inode_t): Change i_wait to i_cnt. Change comment to explain change in usage. (inode_t:use): Rename from wait. Make private. (inode_t::unuse): Rename from unwait. Make private. (inode_t::inuse): Rename from waiting. Make private. (inode_t::notused): New public method to set use count to 0. (inode_t::unlock_and_remove): New method to unlock node and to delete it if it's unused in current process. (fhandler_base::del_my_locks): Drop global list lock. Drop variable no_locks_left. Simpify unlocking and removing node by just calling unlock_and_remove. (fixup_lockf_after_exec): Call notused method for each node. (inode_t::get): Call use method. Lock node only if outside of list lock. (inode_t::get_all_locks_list): Accommodate additional lf_ver field when creating lockf_t structure from object name. (lockf_t::create_lock_obj_attr): Accommodate additional lf_ver field when creating object name from lockf_t structure. Handle STATUS_OBJECT_NAME_COLLISION gracefully in F_POSIX case as well. Change comment accordingly. Increment lf_ver field rather than high byte of lf_wid field. Simplify comment. (fhandler_disk_file::lock): Always call unlock_and_remove rather than just UNLOCK on node. (lf_setlock): Move ret definition where it's used. Drop unneeded tests for obj being not NULL. Only check for deadlock condition if the lock we're trying to establish is a POSIX lock. Revamp object collecting and wait code to cover all cases. Don't return with EDEADLK if blocking process can't be opened for synchronization in F_POSIX case, rather just wait like in F_FLOCK case. Change system_printf to debug_printf in that case. Only run WaitForMultipleObjects with high priority. Close obj and process handles prior to locking node. |

README
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
