[cmd, arg1, arg2...] :param data: input to the command, made available on its stdin. :param rcs: a list of allowed return codes. If subprocess exits with a value not in this list, a ProcessExecutionError will be raised. By default, data is returned as a string. See 'decode' parameter. :param capture: boolean indicating if output should be captured. If True, then stderr and stdout will be returned. If False, they will not be redirected. :param shell: boolean indicating if this should be run with a shell. :param logstring: the command will be logged to DEBUG. If it contains info that should not be logged, then logstring will be logged instead. :param decode: if False, no decoding will be done and returned stdout and stderr will be bytes. Other allowed values are 'strict', 'ignore', and 'replace'. These values are passed through to bytes().decode() as the 'errors' parameter. There is no support for decoding to other than utf-8. :param update_env: update the environment for this command with this dictionary. this will not affect the current processes os.environ. :param cwd: change the working directory to cwd before executing the command. :param timeout: maximum time for the subprocess to run, passed directly to the timeout parameter of Popen.communicate() :return if not capturing, return is (None, None) if capturing, stdout and stderr are returned. if decode: entries in tuple will be string if not decode: entries in tuple will be bytes Nr zFRunning command %s with allowed return codes %s (shell=%s, capture=%s)utf-8)r r stdinenvrP rS )rT g?z%s took %.3ss to runr& -)r) r+ r/ r r c L t | t r| j | S | S Nr7 )rM mr9 s r! ldecodezsubp.<locals>.ldecode s" -7e-D4;;q&) N$ Nr# )r r r* r) )rV )osenvironcopyupdater debug subprocessPIPEDEVNULLr r8 rI r rL time monotonicPopen communicateOSErrorr% r/ returncoder )rG rM rN rO rP rQ r9 rR rS rT rX r r rW bytes_argsxbeforespouterrtotaler] rcs ` r! subpru s1 d {c **// C : II " D F F | ""$&;;=D $ D# [[) &FJ FJAu%A188G+< <d ! >>$>8S 6) 3; II& & D O clcl B }#sbd c3 W , #'' 3d 3 '+ s *G//A=G4 4 H+=)H&&H+c V | dv rd} nSt | t st d| t j j | } | j d r| dd } |s| S t | r!|d dk( r|dd }t | r |d dk( rt j j | | S )N)N /z Unexpected input for target: z//r r ) r r ValueErrorr^ pathabspathr lenr )targetrz s r! target_pathr~ - s $8ABB ( T "ABZF d)Q3ABx d)Q3 77<< %%r# c t | }t j j | v rt t || r| S |t j j dd j t j D cg c] }|j d }}|dk( r|n!|D cg c] }|j d s| c}}|D cg c]! }t j j | # }}|D ]F }t j j j || f }t t || sD|c S y c c}w c c}w c c}w )NPATHrw "rx ) r~ r^ rz sepis_exer_ getsplitpathsepstripr r{ r )programsearchr} ppathsrz ppaths r! whichr B s F ww{{g &VW)E"F ~"$**.."<"B"B2::"N "NQAGGCL"N s]EE(OEqQ\\#=NE(O +1 1&Qbggooa &F 1 $ 1 +fe, -L )P 2s D;%E <E &Ec t j j | xr$ t j | t j S r[ )r^ rz isfileaccessX_OK)fpaths r! r r ] s) 77>>% >RYYubgg%>>r# c < |r t j j | sy g }g }|g }n;t |t r t | g}n t |t r|}n t d t t j | D ] }t j j | | }t | r$|j | t ||gz d Rt j j! | rt j# d| t j d| |r9|r6t% dt' | ddj | d t' | d y y # t $ r1}t j | |j | Y d }~d }~ww xY w) Nz%exe_prefix must be None, str, or listF)rO zjskipping %s as its not executable or the underlying file system is mounted without executable permissions.z Not executing special file [%s]z Runparts: z failures (,z) in z attempted commands)r^ rz isdirr r r r sortedlistdirr r r ru r% r rb r r RuntimeErrorr| ) dirp skip_no_exist exe_prefixfailed attemptedprefixexe_nameexe_pathrs s r! runpartsr b sd RWW]]4 0 FI J $j/" J %?@@2::d+,77<<h/ ( X & (Vxj(%8 WW^^H % KK* II7 B# -& )V [&1A0B%9~ 1 3 v ) ( ! h'' (s E!!
