Attaching file to an email in python leads to a blank file name? -

-

the following snipit of code works fine, except fact resulting attachment file name blank in email (the file opens 'noname' in gmail). doing wrong?

file_name = recordingurl.split("/")[-1]             file_name=file_name+ ".wav"             urlretrieve(recordingurl, file_name)              # create container (outer) email message.             msg = mimemultipart()             msg['subject'] = 'new feedback %s (%a:%a)' % ( from, int(recordingduration) / 60, int(recordingduration) % 60)              msg['from'] = "noreply@example.info"             msg['to'] = 'user@gmail.com'             msg.preamble = msg['subject']                             file = open(file_name, 'rb')             audio = mimeaudio(file.read())             file.close()             msg.attach(audio)              # send email via our own smtp server.             s = smtplib.smtp()             s.connect()             s.sendmail(msg['from'], msg['to'], msg.as_string())             s.quit()

you need add content-disposition header audio part of message using add_header method:

file = open(file_name, 'rb') audio = mimeaudio(file.read()) file.close() audio.add_header('content-disposition', 'attachment', filename=file_name) msg.attach(audio)

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
