aymeric b57e4f3ad4 Fix core dump triggered by a .DEFAULT target with no commands.
Bug reported privately by Nicolas Ollinger <nollinge@ens-lyon.fr>.

You can trigger this bug prior to updating your sources with for example:

sommerfeld 46608f023e bin/12734: fix SIGTSTP/SIGCONT handling.
- install SIGCONT handler which reestablishes SIGTSTP handler and then calls
JobRestartJobs() to restart all the suspended jobs.
 - when SIGTSTP is handled, call JobCatchChildren() so *** Suspended messages
get printed before make stops rather than after.

Well, it should say 'make core-dumps on any error on the primary makefile'.
This was a result of the new changes to print the path to the parsed
Makefile... Made the code a lot more conservative, plus prepended <progname>:
to each message.

sommerfeld a804073cac Add a token-passing scheme to allow a recursive make to successfully
use -j; all make's in a recursive build cooperate to limit the total
number of jobs, using a token-passing scheme.

The current token passing algorithm is similar to the one implemented
by gmake; there is a single pipe which is inherited through the entire
process hierarchy; tokens are obtained by reading a byte from the
"read end" of the pipe, and are returned by writing them to the "write
end".  This exact algorithm is likely to change in the future.

Implementation details:
 - Use the new trace facility to allow measurement of the
effectiveness of different token-passing schemes
 - Get a token in MakeStartJobs(), return it in Make_Update()
 - Eliminate Job_Full() and the jobFull global since they are
redundant with token system.
 - Add an "internal" -J option (to pass the token pipe fd's down to
submakes) and a -T option for tracing.
 - Change how compatMake is forced so that -j means something when
inherited by submakes.
 - When waiting for a token, poll the token-passing pipe as well as
the output pipes of existing jobs.

2000-12-05 15:28:55 +00:00
sommerfeld b5e2403ec9 correct performance regression of recent change from select() to
poll() for parallel make:
 - Make the poll() code behave more like the select() code: sleep for
a bit waiting for output rather than busy-wait (eww).
 - Install a no-op SIGCHLD handler so that poll/select wake up early
(with -1/EINTR) when a child exits.
 - Change the default sleep time from 500ms to 5 seconds since we now
wake up promptly when a child exits.

mycroft 796fb2ec8c Readd optimization last night. Problems earlier were partially due to the
arguments names on one function being swapped (by a previous author).

Do not do any duplicate suppression when a source list is created.  Instead:
* OP_MADE protects against trying to make the source multiple times.
* A new OP_MARK flag is introduced to suppress duplicates while expanding
  the .ALLSRC variable and .USE targets.
This turns the O(n^2) insertion into O(n) in most cases.

This is tested with a `make build' and some special test cases.

sjg 339f702f71 Implemented a set of assignment modifiers. These solve obscure
problems such as using modifiers on .for loop iterators derived from

local to the current context (this is usually what is wanted).

sjg 0828d668af Changes to make MAKEOBJDIRPREFIX useful.
Firstly, we ignore getenv("PWD") if MAKEOBJDIRPREFIX is set so that we always
get the same value for .CURDIR regardless of how make was invoked.

Second, when executing a command we check if it is ${.MAKE} or ${.MAKE:T}
without a preceeding chdir, if so we insert a chdir(${.CURDIR}) so that
the Makefile will be found by the child make.  Note that this behaviour is
dissabled if MAKEOBJDIRPREFIX is not set or if NOCHECKMAKECHDIR is set.
See the comments in main.c for more detail.

With these two changes, one can successfully build usr/src using MAKEOBJDIRPREFIX
allowing the src to be mounted from a CD-ROM.

christos 4f3cc30bcc This patch fixes the problem introduced in the previous commit where
parents would be get remade, even if children were not really updated
by the commands executed for them. It also makes all the children have
the real modification time set if possible, so it should fix some other
timing weirdnesses...

- collapse childMade and make fields into flags and convert them to bits
  CHILDMADE and REMAKE
- introduce FORCE flag that gets set in all the parents of a child that
  has no sources and does not exist.
- set oodate if the FORCE flag is set, and not if CHILDMADE
- centralize the RECHECK into Make_Recheck() and use this in make.c and compat.c
- use Make_TimeStamp for all child -> parent timestamp propagations

christos 7e91b1976d PR/6426: Jim Bernard: make sometimes does not make directories on top of
a union mount.

	eg.
	src: FORCE

	FORCE is a fake target that does not have sources. When FORCE is
	considered made it gets updated with the current timestamp. If the
	directory happens to have the same timestamp too, then it will not
	be made because it is considered to be up-to-date with respect to
	the child. This can happen because the time resolution is only in
	seconds. It is more likely to happen on a union filesystem where
	the timestamps take longer to update.

	The fix is to consider the parent unmade when children have been
	updated.
