This is achieved by creating a temporary socket with the same family and type as the 'sock' parameter (default is AF_INET, SOCK_STREAM), and binding it to the specified host address (defaults to 0.0.0.0) with the port set to 0, eliciting an unused ephemeral port from the OS. The temporary socket is then closed and deleted, and the ephemeral port is returned. Either this method or bind_port() should be used for any tests where a server socket needs to be bound to a particular port for the duration of the test. Which one to use depends on whether the calling code is creating a python socket, or if an unused port needs to be provided in a constructor or passed to an external program (i.e. the -accept argument to openssl's s_server mode). Always prefer bind_port() over find_unused_port() where possible. Hard coded ports should *NEVER* be used. As soon as a server socket is bound to a hard coded port, the ability to run multiple instances of the test simultaneously on the same host is compromised, which makes the test a ticking time bomb in a buildbot environment. On Unix buildbots, this may simply manifest as a failed test, which can be recovered from without intervention in most cases, but on Windows, the entire python process can completely and utterly wedge, requiring someone to log in to the buildbot and manually kill the affected process. (This is easy to reproduce on Windows, unfortunately, and can be traced to the SO_REUSEADDR socket option having different semantics on Windows versus Unix/Linux. On Unix, you can't have two AF_INET SOCK_STREAM sockets bind, listen and then accept connections on identical host/ports. An EADDRINUSE OSError will be raised at some point (depending on the platform and the order bind and listen were called on each socket). However, on Windows, if SO_REUSEADDR is set on the sockets, no EADDRINUSE will ever be raised when attempting to bind two identical host/ports. When accept() is called on each socket, the second caller's process will steal the port from the first caller, leaving them both in an awkwardly wedged state where they'll no longer respond to any signals or graceful kills, and must be forcibly killed via OpenProcess()/TerminateProcess(). The solution on Windows is to use the SO_EXCLUSIVEADDRUSE socket option instead of SO_REUSEADDR, which effectively affords the same semantics as SO_REUSEADDR on Unix. Given the propensity of Unix developers in the Open Source world compared to Windows ones, this is a common mistake. A quick look over OpenSSL's 0.9.8g source shows that they use SO_REUSEADDR when openssl.exe is called with the 's_server' option, for example. See http://bugs.python.org/issue2550 for more info. The following site also has a very thorough description about the implications of both REUSEADDR and EXCLUSIVEADDRUSE on Windows: http://msdn2.microsoft.com/en-us/library/ms740621(VS.85).aspx) XXX: although this approach is a vast improvement on previous attempts to elicit unused ports, it rests heavily on the assumption that the ephemeral port returned to us by the OS won't immediately be dished back out to some other process when we close and delete our temporary socket but before our calling code has a chance to bind the returned port. We can deal with this issue if/when we come across it. )socketr?close)familyZsocktypeZtempsockportrWrWrXr>bs 8  c Cs |jtjkr|jtjkrttdr]|jtjtjdkr]t dttdrdt j kry.|jtjtj dkrt dWnt k rYnXttdr|jtjtjd|j|df|jd}|S) a%Bind the socket to a free port and return the port number. Relies on ephemeral ports in order to ensure we are using an unbound port. This is important as many tests may be running simultaneously, especially in a buildbot environment. This method raises an exception if the sock.family is AF_INET and sock.type is SOCK_STREAM, *and* the socket has SO_REUSEADDR or SO_REUSEPORT set on it. Tests should *never* set these socket options for TCP/IP sockets. The only case for setting these options is testing multicasting via multiple UDP sockets. Additionally, if the SO_EXCLUSIVEADDRUSE socket option is available (i.e. on Windows), it will be set on the socket. This will prevent anyone else from bind()'ing to our host/port for the duration of the test. SO_REUSEADDRrzHtests should never set the SO_REUSEADDR socket option on TCP/IP sockets!

'size' is a requested size for the test (in arbitrary, test-interpreted units.) 'memuse' is the number of bytes per unit for the test, or a good estimate of it. For example, a test that needs two byte buffers, of 4 GiB each, could be decorated with @bigmemtest(size=_4G, memuse=2). The 'size' argument is normally passed to the decorated test method as an extra argument. If 'dry_run' is true, the value passed to the test method may be less than the requested value. If 'dry_run' is false, it means the test doesn't support dummy runs when -M is not specified. cs.fdd__S)Nc sj}j}ts!d}n|}ts4 r_t||kr_tjd||dtrtrttdjd||dt}|j nd}z||SWd|r|j XdS) Niz'not enough memory: %.1fG minimum neededirz* ... expected peak memory use: {peak:.1f}GZpeaki@i@) rmemuserrfrgrrrrrr)rMrrmaxsizeZwatchdog)dry_runrurrWrXrs*        z.bigmemtest..decorator..wrapper)rr)ru)rrr)rurrXrs  zbigmemtest..decoratorrW)rrrrrW)rrrrXr/s !csfdd}|S)z0Decorator for tests that fill the address space.cs^ttkrPtd kr6td kr6tjdqZtjdtd n |SdS) Nr?rz-not enough memory: try a 32-bit build insteadz'not enough memory: %.1fG minimum neededirllli@)rrrfrg)rM)rurWrXrs  z!bigaddrspacetest..wrapperrW)rurrW)rurXr0s c@seZdZddZdS)r(cCstj}|||S)N)rfZ TestResult)rMrrrWrWrXruns  zBasicTestRunner.runN)rSrTrUrrWrWrWrXr(s cCs|S)NrW)rrWrWrX_idsrcCsP|dkr&t r&tjtjSt|r6tStjdj|SdS)Nrzresource {0!r} is not enabled)rrfskiprrrr)rrWrWrXrequires_resources  rcCstdd|S)z9 Decorator for tests only applicable on CPython. cpythonT) impl_detail)rrWrWrXr1scKszt|rtS|dkrmt|\}}|r=d}nd}t|j}|jdj|}tj|S)Nz*implementation detail not available on {0}z%implementation detail specific to {0}z or ) r;r _parse_guardsr+ryrrrfr)rkguardsZ guardnamesdefaultrWrWrXrs   rc CsjtdkrGddl}y|jdaWntk rFdaYnXd}trW|Stj||S)z8Skip decorator for tests that use multiprocessing.Queue.NrTFz6requires a functioning shared semaphore implementation)_have_mp_queuemultiprocessingZQueuerarfr)rrrkrWrWrXr9s      cCsb|sddidfSt|jd}t|j|gt|ksWt|| fS)NrTFr)rovaluesrra)rZis_truerWrWrXrs +rcKs.t|\}}|jtjj|S)a5This function returns True or False depending on the host platform.
