To avoid the need for each process to check the filesystem to detect that hardlink creation is impossible or disabled, cache this fact in shared memory. Removing cygfork directory while in use does disable hardlinks creation. To (re-)enable hardlinks creation, the cygfork directory has to exist before the first cygwin process does fork. * forkable.cc (dll_list::forkable_ntnamesize): Short cut forkables needs to impossible when disabled via shared memory. (dll_list::update_forkables_needs): When detecting hardlink creation as impossible (not on NTFS) while still (we are the first one checking) enabled via shared memory, disable the shared memory value. (dll_list::request_forkables): Disable the shared memory value when hardlinks creation became disabled, that is when the cygfork directory was removed. * include/cygwin/version.h: Bump CYGWIN_VERSION_SHARED_DATA 6. * shared_info.h (struct shared_info): Add member prefer_forkable_hardlinks. Update CURR_SHARED_MAGIC. * shared.cc (shared_info::initialize): Initialize prefer_forkable_hardlinks to 1 (Yes).
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.
