Instead of recreating buffers of dubious appropriate size, have one single buffer for various stages of parsing. 2019-12-21T15:26:47Z espie espie@openbsd.org 2019-12-21T15:26:47Z urn:sha1:7a167ac6e6df0732e4a58c841fac68d30ce6f307 - make BufExpand a real function, zap BufOverflow - sprinkle assert that justify the arithmetic - use unsigned constants - fix a bug in the unlikely condition where Buf_printf would exactly match the buffer boundary and Buf_Retrieve would be called right after okay millert@ 2015-04-29T00:42:12Z millert millert@openbsd.org 2015-04-29T00:42:12Z urn:sha1:14e4c4f434ccc5abd1d194d4416ab10381093ed2 2015-04-25T15:33:47Z espie espie@openbsd.org 2015-04-25T15:33:47Z urn:sha1:0f2017b9a5fc3429d67d638b7b9b58ce646524f7 better style code). Problem noticed by deraadt@ in m4. okay doug@ deraadt@ 2012-11-07T14:18:41Z espie espie@openbsd.org 2012-11-07T14:18:41Z urn:sha1:9b06ba05b9bf7c7475ee344dc5803b069c5fbc9e this was yet another weirdness in our make that isn't shared by other makes, and that isn't part of any standard. This means end-of-line spaces in variables ARE significant (spaces around the equal sign still aren't). okay sthen@, "sounds fine" deraadt@ 2012-09-21T07:55:20Z espie espie@openbsd.org 2012-09-21T07:55:20Z urn:sha1:a6b963c87274c1e621c41f7b2a144ca0c6461d0b instead of forking a "job" per target, and having that job further fork separate commands, have make maintain a list of jobs, indexed by pid of currently running commands, and handle process termination continuation-style. This has lots of benefits: - make is responsible for most printing, so we no longer need pipes nor job control: make -j jobs see the tty. - no more special-casing for jobs that don't really execute anything. - unify code for make -jn and make -B, including signal handlers and job waiting. So make -n, make -q, +cmd now run commands in the same way in all cases. - unified more accurate error-reporting, as make knows precisely which command failed. Commands are tagged with their lines, and we display failing commands in silent mode. - fine-grained "expensive" command handling (recursion limiter). Do it per-command instead of per-target. Moreover, signal response is now simpler, as we just block the signals in a small critical sections, test for events, and sigpause (thanks a lot to guenther@ and millert@), so running make is now almost always paused without any busy-waiting. Thanks to everyone who tested and gave input. 2010-07-19T19:46:43Z espie espie@openbsd.org 2010-07-19T19:46:43Z urn:sha1:bb4544df9ace63bacb4f113c781faab96bfc1dec 2010-07-19T19:30:37Z espie espie@openbsd.org 2010-07-19T19:30:37Z urn:sha1:dba68890dc2f821a2767fe1773a14cfff3b41f2a - allow variables in SysV modifiers, as requested by matthieu@ (since recursive variables are an extension, this just extends the extension) - variation on :Q called :QL (quote list), which does quote every character EXCEPT for whitespace. e.g., toto: @for i in ${VAR:QL} ... 2007-07-24T21:09:07Z espie espie@openbsd.org 2007-07-24T21:09:07Z urn:sha1:dac15098a862b4d940f37f099c78dddd7cd32334 2004-04-07T13:11:35Z espie espie@openbsd.org 2004-04-07T13:11:35Z urn:sha1:ad2b054bebd0334fa80f540ca557dcc7d348b908 more explicit/more consistent names. okay otto@
