As of coreutils 6.9-4, dd honors the > oflag=binary option in the popen() context in which I've been having > trouble. Before you thank me too much, remember that oflag=binary already worked even in coreutils 6.9-3; it was the absence of any oflag= that was incorrectly obeying mount points instead of defaulting to binary. > FILE * const out = popen("gzip | dd oflag=binary > popenbug.out.gz", "w"); Why not also thank cgf, who uploaded a fixed gzip yesterday? Because of his fix, this should now work: popen("gzip > popenbug.out.gz", "w") > However, in the discussion and the updated coreutils announcement > http://cygwin.com/ml/cygwin/2007-07/msg00610.html > http://cygwin.com/ml/cygwin/2007-07/msg00617.html Did you not read my statement that: [io]f= unspecified - no change to existing mode of std{in,out} I did not change that behavior, nor did I claim to change it in 6.9-4. I am still open to the idea of changing it. For 6.9-4, I only changed the behavior for when of= but not oflag= was specified. - -- Don't work too hard, make some time for fun as well!
