7.301. gzip

Bug Fix

BZ#963195

The O_NONBLOCK flag was recently added to the open() system call. As a consequence gzip did not prevent opening of parity (PAR) and Ots File List (OFL) files that are managed by the SGI Data Migration Facility (DMF). Processing of such files resulted in gzip aborts or corrupted output files. With this update, if an attempt to read a file with the O_NONBLOCK flag fails with the EAGAIN error code, the file is re-read without O_NONBLOCK. The gzip utility no longer aborts or produce corrupted output files in this situation.
