The feed parser implements an interface for incrementally parsing an email message, line by line. This has advantages for certain applications, such as those reading email messages off a socket. FeedParser.feed() is the primary interface for pushing new data into the parser. It returns when there's nothing more it can do with the available data. When you have no more data to push into the parser, call .close(). This completes the parsing and returns the root message object. The other advantage of this parser is that it will never raise a parsing exception. Instead, when it finds something unexpected, it adds a 'defect' to the current message. Defects are just instances that live on the message object's .defects attribute. t FeedParseriN(terrors(tmessages | | s( | | )s ( | | )\Zs(^(From |[\041-\071\073-\176]{1,}:|[\t ])ts tBufferedSubFilecBsqeZdZdZdZdZdZdZdZdZ dZ d Z d Z d Z RS( skA file-ish object that can have new data loaded into it. You can also push and pop line-matching predicates onto a stack. When the current predicate matches the current line, a false EOF response (i.e. empty string) is returned instead. This lets the parser adhere to a simple abstraction -- it parses until EOF closes the current message. cCs(g|_g|_g|_t|_dS(N(t_partialt_linest _eofstacktFalset_closed(tself((s(/usr/lib64/python2.7/email/feedparser.pyt__init__3s   cCs|jj|dS(N(Rtappend(R tpred((s(/usr/lib64/python2.7/email/feedparser.pytpush_eof_matcher=scCs |jjS(N(Rtpop(R ((s(/usr/lib64/python2.7/email/feedparser.pytpop_eof_matcher@scCs8|jdj|jjtg|_t|_dS(NR(t pushlinestjoinRt splitlinestTrueR (R ((s(/usr/lib64/python2.7/email/feedparser.pytcloseCs" cCsn|js|jrdStS|jj}x>|jdddD]&}||r@|jj|dSq@W|S(NRi(RR t NeedMoreDataRRR (R tlinetateof((s(/usr/lib64/python2.7/email/feedparser.pytreadlineIs   cCs&|tk st|jj|dS(N(RtAssertionErrorRR (R R((s(/usr/lib64/python2.7/email/feedparser.pyt unreadline[scCs|jt}| s*|djd r=|j|7_dS|jr|jj|ddj|jjt|dd+|j2n|djds|jg|_n|j|dS( s$Push some new data into this object.is s NRii(s s (RRtendswithRR RRR(R tdatatparts((s(/usr/lib64/python2.7/email/feedparser.pytpush`s " cCs|ddd|jd*dS(Nii(R(R tlines((s(/usr/lib64/python2.7/email/feedparser.pyRxscCs|jS(N(R (R ((s(/usr/lib64/python2.7/email/feedparser.pyt is_closed|scCs|S(N((R ((s(/usr/lib64/python2.7/email/feedparser.pyt__iter__scCs%|j}|dkr!tn|S(NR(Rt StopIteration(R R((s(/usr/lib64/python2.7/email/feedparser.pytnexts   (t__name__t __module__t__doc__R RRRRRRRR!R"R$(((s(/usr/lib64/python2.7/email/feedparser.pyR+s         cBseeZdZejdZdZdZdZdZ dZ dZ dZ d Z RS( sA feed-style parser of email.cCsO||_t|_g|_|jj|_d|_d|_ t |_ dS(s@_factory is called with no arguments to create a new message objN( t_factoryRt_inputt _msgstackt _parsegenR$t_parsetNonet_curt_lastRt _headersonly(R R(((s(/usr/lib64/python2.7/email/feedparser.pyR s     cCs t|_dS(N(RR0(R ((s(/usr/lib64/python2.7/email/feedparser.pyt_set_headersonlyscCs|jj||jdS(sPush more data into the parser.N(R)Rt _call_parse(R R((s(/usr/lib64/python2.7/email/feedparser.pytfeedscCs&y|jWntk r!nXdS(N(R,R#(R ((s(/usr/lib64/python2.7/email/feedparser.pyR2s cCso|jj|j|j}|j s3t|jdkrk|j rk|jj t j n|S(s<Parse all remaining data and return the root message object.t multipart( R)RR2t _pop_messageR*Rtget_content_maintypet is_multiparttdefectsR Rt!MultipartInvariantViolationDefect(R troot((s(/usr/lib64/python2.7/email/feedparser.pyRs    cCs|j}|jr:|jjdkr:|jdn|jrZ|jdj|n|jj|||_||_dS(Nsmultipart/digestsmessage/rfc822i(R(R.tget_content_typetset_default_typeR*tattachR R/(R tmsg((s(/usr/lib64/python2.7/email/feedparser.pyt _new_messages   cCs8|jj}|jr+|jd|_n d|_|S(Ni(R*RR.R-(R tretval((s(/usr/lib64/python2.7/email/feedparser.pyR5s   ccs|jg}xj|jD]_}|tkr7tVqntj|sltj|sh|jj|nPn|j|qW|j||j rg}xMt r|jj }|tkrtVqn|dkrPn|j|qW|j j tj|dS|j jdkrxt r |jjtjx,|jD]}|tkratVqDnPqDW|j}|jjx1t r|jj }|tkrtVqnPqWx1t r|jj }|tkrtVqnPqW|dkrPn|jj|qWdS|j jdkrax,|jD]}|tkrNtVq1nPq1W|jdS|j jdkr:|j j}|dkr|j jjtjg}x5|jD]*}|tkrtVqn|j|qW|j j tj|dSd|}tjdtj|d}t } g} t} xt r|jj }|tkrptVqDn|dkrPn|j|} | r| jdr| jd } Pn| r7| r| d } t j!| }|r| t"|jd  | d s4)(?P--)?(?P[ \t]*)(?P\r\n|\r|\n)?$tendtlinesepii(,R?R)RtheaderREtmatchtNLCRERR t_parse_headersR0RRR.t set_payloadt EMPTYSTRINGRR;RR+R5RR6t get_boundaryR-R8RtNoBoundaryInMultipartDefecttretcompiletescapeRtgroupt NLCRE_eoltsearchtlentpreambleR/tepiloguet get_payloadt isinstancet basestringRtStartBoundaryNotFoundDefectt NLCRE_bol(R theadersRR R@R>tboundaryt separatort boundaryretcapturing_preambleRRRBtmotlastlineteolmoRSRAtpayloadt firstlinetbolmo((s(/usr/lib64/python2.7/email/feedparser.pyR+sL                          !              # c Csd}g}xt|D]\}}|ddkrv|sctj|}|jjj|qn|j|qn|rtj|d jd}||j|s   _
