Python batch-rename script sending files to root folder -

-

ok, weird , maybe awkward. made script change end of subtitles files keep consistency. replaces a.x.str a.y.str. worked flawlessly @ single folder.

i decided make recursive version of on folder had, regardless if episodes together, separated season or each on individual path.

i don't know how or why, sent files reached root folder using until halted raising fileexistserror.

the code bit i'm using is:

def rewrite(folder, old, new):     f in next(os.walk(folder))[2]:         os.rename(os.path.join(folder, f),                   os.path.join(path, f.replace(old, new)))     f in next(os.walk(folder))[1]:         x = os.path.join(folder, f)         rewrite(x, old, new)

where 'old' "a.x.str", 'new' "a.y.str" , folder full path of root folder "c:\series\serie name".

why doesn't work recursive? first bit of code (first loop) works fine on it's own in single folder. problem "next" use names of files , folders?

the code showing using path variable in rename destination -- should folder variable instead.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
