* strace: Fix "over-optimization" flaw in strace.Daniel Santos2017-04-191-1/+1
| | | | | | | | Recent versions of gcc are optimizing away the TLS buffer allocated in main, so we need to tell gcc that it's really used. RtlSecureZeroMemory accomplishes this while also inlining the memset. Signed-off-by: Daniel Santos <daniel.santos@pobox.com>
* Generate output with Unix line endings even from Mingw64 utilsCorinna Vinschen2017-02-241-0/+4
| | | | | | This affects cygcheck and strace. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* strace: Don't print exception info for SetThreadName exceptionCorinna Vinschen2016-08-311-2/+6
| | | | | | | | | | The new functionality to set the thread name for debugging purposes creates exception debugging events. These are printed out when running strace. Since these exceptions have nothing to do with real exceptions but are, like breakpoint execptions, expected and non-fatal, don't print exception info for them.

* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-4/+1
| | | | | | | | | | | | | | 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>

* Improve strace to log most Windows debug eventsJon TURNEY2015-06-111-2/+73
| | | | | | | | | | | | | | | | | | | | Not sure if this is wanted, but on a couple of occasions recently I have been presented with strace output which contains an exception at an address in an unknown module (i.e. not in the cygwin DLL or the main executable), so here is a patch which adds some more information, including DLL load addresses, to help interpret such straces. v2: Use NtQueryObject() for HANDLE -> filename conversion Add new '-e' option to toggle this additional logging 2015-06-07 Jon Turney <jon.turney@dronecode.org.uk> * strace.cc (proc_child): Log process and thread create and exit, and DLL load and unload. (GetFileNameFromHandle): New function. Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk>
