These errors look like the following: Failed to run "['/home/buildbot/WebKit/Tools/Scripts/webkit-patch', '--status-host=webkit-queues.appspot.com', '--bot-id=ews204', 'clean', '--port=win']" exit_code: 1 cwd: /home/buildbot/WebKit 0 [main] python2.7 716 child_info_fork::abort: address space needed by 'cygffi-6.dll' (0x3F0000) is already occupied Traceback (most recent call last): File "/home/buildbot/WebKit/Tools/Scripts/webkit-patch", line 84, in <module> main() File "/home/buildbot/WebKit/Tools/Scripts/webkit-patch", line 79, in main WebKitPatch(os.path.abspath(__file__)).main() File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/tool/multicommandtool.py", line 296, in main self.handle_global_options(options) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/tool/main.py", line 94, in handle_global_options self.initialize_scm(options.patch_directories) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/host.py", line 81, in initialize_scm self._checkout = Checkout(detector.default_scm(patch_directories)) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/detection.py", line 55, in default_scm scm_system = self.detect_scm_system(cwd, patch_directories) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/detection.py", line 72, in detect_scm_system return SVN(cwd=absolute_path, patch_directories=patch_directories, filesystem=self._filesystem, executive=self._executive) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/svn.py", line 81, in __init__ SCM.__init__(self, cwd, **kwargs) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/scm.py", line 67, in __init__ self.checkout_root = self.find_checkout_root(self.cwd) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/svn.py", line 125, in find_checkout_root if uuid != self.find_uuid(path): File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/svn.py", line 103, in find_uuid if not self.in_working_directory(path): File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/checkout/scm/svn.py", line 99, in in_working_directory exit_code = executive.run_command(svn_info_args, cwd=path, return_exit_code=True) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/system/executive.py", line 435, in run_command close_fds=self._should_close_fds()) File "/home/buildbot/WebKit/Tools/Scripts/webkitpy/common/system/executive.py", line 506, in popen return subprocess.Popen(string_args, **kwargs) File "/usr/lib/python2.7/subprocess.py", line 710, in __init__ errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1223, in _execute_child self.pid = os.fork() OSError: [Errno 11] Resource temporarily unavailable It seems like moving away from running Windows EWS on top of Cygwin would provide a significant boost in reliability. 1062042 1 bfulgham 2015-01-16 16:49:28 -0800 It might also be possible to somehow work the Cygwin 'rebaseall' script into our cycle. 1064324 2 webkit-bug-importer 2015-01-26 18:08:27 -0800 <rdar://problem/19609012> 2018861 3 fujii 2024-03-05 12:56:39 -0800 AppleWin was removed.
