Smith <psmith@gnu.org> + + * function.c (func_if): New function $(if ...) based on the + original by Han-Wen but reworked quite a bit. + (function_table): Add it. + * NEWS: Introduce it. + * make.texinfo (If Function): Document it. + + * job.c (free_job_token): Check for EINTR when writing tokens to + the jobserver pipe. + +1999-08-12 Paul D. Smith <psmith@gnu.org> + + Argh. Another jobserver algorithm change. We conveniently forgot + that the blocking bit is shared by all users of the pipe, it's not + a per-process setting. Since we have many make processes all + sharing the pipe we can't use the blocking bit as a signal handler + flag. Instead, we'll dup the pipe's read FD and have the SIGCHLD + handler close the dup'd FD. This will cause the read() to fail + with EBADF the next time we invoke it, so we know we need to reap + children. We then re-dup and reap. + + * main.c (main): Define the job_rfd variable to hold the dup'd FD. + Actually dup the read side of the pipe. Don't bother setting the + blocking bit on the file descriptor. + * make.h: Declare the job_rfd variable. + * job.c (child_handler): If the dup'd jobserver pipe is open, + close it and assign -1 to job_rfd to notify the main program that + we got a SIGCHLD. + (start_job_command): Close the dup'd FD before exec'ing children. + Since we open and close this thing so often it doesn't seem + worth it to use the close-on-exec bit. + (new_job): Remove code for testing/setting the blocking bit. + Instead of EAGAIN, test for EBADF. If the dup'd FD has been + closed, re-dup it before we reap children. + + * function.c (func_shell): Be a little more accurate about the + length of the error string to allocate. + + * expand.c (variable_expand_for_file): If there's no filenm info + (say, from a builtin command) then reset reading_file to 0. + 1999-08-09 Paul D. Smith <psmith@gnu.org> * maintMakefile: Use g in sed (s///g) to replace >1 variable per line. - * Makefile.DOS.template: Fix mostlyclean-aminfo to remove the - right stuff. + * Makefile.DOS.template [__MSDOS__]: Fix mostlyclean-aminfo to + remove the right files. 1999-08-01 Eli Zaretskii <eliz@is.elta.co.il> - * function.c (msdos_openpipe): *Really* return a FILE ptr. + * function.c (msdos_openpipe) [__MSDOS__]: *Really* return a FILE + ptr. 1999-08-01 Paul D.
