In pipe_fork callers, use these named constants, not "2" and "8". (proctab, nprocs): Declare to be "static". (pipe_fork) [lint]: Initialize local, pid, to avoid unwarranted may-be-used-uninitialized warning. (create_temp): Use the active voice. Describe parameters, too. 2007-01-21 James Youngman <jay@gnu.org> Centralize all the uses of sigprocmask(). Don't restore an invalid saved mask. * src/sort.c (enter_cs, leave_cs): New functions for protecting code sequences against signal delivery. * (exit_cleanup): Use enter_cs and leave_cs instead of calling sigprocmask directly. (create_temp_file, pipe_fork, zaptemp): Likewise 2007-01-21 Dan Hipschman <dsh@linux.ucla.edu> Add compression of temp files to sort. * NEWS: Mention this. * bootstrap.conf: Import findprog. * configure.ac: Add AC_FUNC_FORK. * doc/coreutils.texi: Document GNUSORT_COMPRESSOR environment variable. * src/sort.c (compress_program): New global, holds the name of the external compression program. (struct sortfile): New type used by mergepfs and friends instead of filenames to hold PIDs of compressor processes. (proctab): New global, holds compressor PIDs on which to wait. (enum procstate, struct procnode): New types used by proctab. (proctab_hasher, proctab_comparator): New functions for proctab. (nprocs): New global, number of forked but unreaped children. (reap, reap_some): New function, wait for/cleanup forked processes. (register_proc, update_proc, wait_proc): New functions for adding, modifying and removing proctab entries. (create_temp_file): Change parameter type to pointer to file descriptor, and return type to pointer to struct tempnode. (dup2_or_die): New function used in create_temp and open_temp. (pipe_fork): New function, creates a pipe and child process. (create_temp): Creates a temp file and possibly a compression program to which we filter output. (open_temp): Opens a compressed temp file and creates a decompression process through which to filter the input. (mergefps): Change FILES parameter type to struct sortfile array and update access accordingly. Use open_temp and reap_some. (avoid_trashing_input, merge): Change FILES parameter like mergefps and call create_temp instead of create_temp_file. (sort): Call create_temp instead of create_temp_file. Use reap_some. (avoid_trashing_input, merge, sort, main): Adapt to mergefps.
