* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-3/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Do not treat the command line or environment like pathsJohannes Schindelin2016-01-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | * dcrt0.cc (dll_crt0_1), environ.cc (environ_init, getwinenveq, build_env), strfuncs.cc (sys_wcstombs, sys_wcstombs_alloc), wchar.c (sys_wcstombs, sys_wcstombs_alloc): avoid mis-conversions of text that does not, actually, refer to a path or file name Detailed explanation: Our WCS -> UTF conversion handles the private Unicode page specially to allow for otherwise invalid file names. However, this handling makes no sense for command-lines, nor environment variables, which we would rather convert verbatim. As a stop-gap solution, let's just introduce a version of the sys_wcstombs() function that specifically excludes that file name conversion magic. The proper solution is to change sys_wcstombs() to assume that it is not a path that wants to be converted, and introduce sys_wcstombs_path() that does, but that is a bigger task which we leave for another patch.

* Always allocate main thread stack from pthread stack area on x86_64.Corinna Vinschen2015-12-071-36/+48
| | | | | | | | | | | | | | | | | | | | | | | | | * dcrt0.cc: Semi-revert commit 12743c2d5d2721f3a80b4d7671a349be03c1f520. (dll_crt0_0): Drop setting wow64_needs_stack_adjustment on 64 bit. (_dll_crt0): Split out 64 bit code again and always create new main thread stack, unless forked off from the non main thread in the parent. Call create_new_main_thread_stack with parent stack commitsize if started from the parent's main thread. Only call child_info_fork::alloc_stack for the latter case on 64 bit. Slightly rearrange moving rsp and rbp to new stack and document how. Revert 32 bit wow64 handling to its former self. * miscfunc.cc (create_new_main_thread_stack): Take a commitsize parameter and use it if it's not 0. Don't set _main_tls here, it's done in the caller _dll_crt0 anyway. Return stackbase - 16 bytes, rather than stacklimit (which was very wrong anyway). * miscfuncs.h (create_new_main_thread_stack): Accommodate declaration to aforementioned change. * wincap.h (wincaps::has_3264_stack_broken): Remove element. * wincap.cc: Ditto, throughout. * wow64.cc: Semi-revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520 but keep architecture-agnostic type changes intact.
