https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D210537 --- Comment #10 from Eugene Grosbein <eugen@freebsd.org> --- (In reply to Mikhail T. from comment #9) > cron-jobs aren't supposed to spit /anything/ to standard output They are, as any other shell command. > why should the logic be any different, if I switched to fetching a JPG? Because SMTP does not support unencoded arbitrary binary data. That is, "Content-Transfer-Encoding: binary" is not supported in the Internet e-mail= : no MTA is supposed to to receive and process such data, and many do not. And I don't think we should make cron to perform MIME encoding. > What overhead? libmagic processing may be expensive in terms of I/O, memory and CPU times. Have you tried to evaluate this overhead using some slow CPU like Intel Ato= m or ARM or MIPS32? You may be surprised. It evolves reading significant amount = of libmagic own data and I/O may be slow due to slow media like CompactFlash. = Then it may run plenty regexp's against input data. The whole process can easily long for seconds of wall time making measurable system load. Such processing should be opt-in, not opt-out. --=20 You are receiving this mail because: You are the assignee for the bug.=
