That would be okay, except that the new socket.ssl objects provide only read() and write(), so they don't act like a socket /or/ like a file. Argh. This class takes a standard, connected socket.socket() object, sets it to blocking mode (required for socket.ssl() to work correctly, though apparently not documented), wraps .write() for .sendall() and implements .readline(). The modified POP3 class below can then use this to provide POP3-over-SSL. Thanks to Frank Benkstein for the inspiration. cCsxtjƒ||_|jjdƒ|rM|rMtj|j||ƒ|_ntj|jƒ|_d|_d|_dS(Niti€(tlogttracetsockt setblockingtsockettssltbuftbufsize(tselfR tkeyfiletcertfile((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyt__init__$s    cCsƒtjƒ|jt|jƒ}tjd|ƒ|dkrAdS|jj|ƒ}t|ƒ}tjd|ƒ|j|7_dS(s8Fill an internal buffer for .readline() to use. swant %i bytes iNs got %i bytes (R R RtlenRRtread(Rtwanttstgot((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyt_fillbuf/s   cCs|jjƒd|_dS(N(R tclosetNoneR(R((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyR<s cCs|jj|ƒdS(N(Rtwrite(RR((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pytsendallAscCs{tjƒd}y5|js)|jƒntjdƒ|jr/tjd|jt|jƒfƒxĘtr+tjdƒ|jjdƒ}|dkrÔtjd|ƒ||j|d 7}|j|d|_Pntjd ƒ||j7}d|_|jƒ|jstjd ƒPntjd ƒqeWntjd |ƒ|SWn/tjtj fk rv}t d |ƒ‚nXdS(sfSimple hack to implement .readline() on a non-file object that only supports .read().

Note that Python's socket module does not do certificate verification for SSL connections. This gets rid of the .file attribute from os.makefile(rawsock) and relies on sslsocket() above to provide .readline() instead. c Csz|r |p%||ko#dkns7tdƒ‚n||_||_d}d|_d|_xâtj|j|jdtjƒD]ż}|\}}} } } yetj||| ƒ|_|jj | ƒ|rđ|rđt |j||ƒ|_nt |jƒ|_Wn;tj k r@}|jr1|jj ƒnd|_qƒnXPqƒW|js^tj |‚nd|_ |jƒ|_dS(Nscertfile requires keyfiles!getaddrinfo returns an empty listi(RtgetmailConfigurationErrorthosttporttrawsockR Rt getaddrinfot SOCK_STREAMtconnectRR#Rt _debuggingt_getresptwelcome( RR-R.RRtmsgtrestaftsocktypetprotot canonnametsa((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyRss4(         cCs™|jjƒ}|jdkr+dG| GHn|s@tdƒ‚nt|ƒ}|dtkrj|d |fS|dtkr‹|dd!|fS|d |fS(Nis*get*s-ERR EOFiţ˙˙˙ii˙˙˙˙(R R(R3RRRR(RR%toctets((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyt_getline“s  cCsOy|jdƒ}Wn"ttjfk r7}|}nX|jjƒ|`|S(sMSignoff: commit changes on server, unlock mailbox, close connection. tQUIT(t _shortcmdRRR#R R(Rtresptval((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pytquitŁs  N(R)R*R+RRRR>RC(((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyRks (R+t__all__RtpoplibRRRRRtgetmailcore.exceptionstgetmailcore.loggingt getmailcoretloggingtLoggerR RtobjectRR(((s8/usr/lib/python2.7/dist-packages/getmailcore/_pop3ssl.pyts  (  V
