We now just list the names of such variables in .MAKEOVERRIDES.
When we come to export MAKEFLAGS we quote the value of each exported variable
using :Q, using: ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
The :O:u suppresses duplicate names.
Also modifed Parse_DoVar to re-export MAKEFLAGS whenever .MAKEOVERRIDES
is assigned to so .MAKEOVERRIDES+= PATH will export PATH=${PATH:Q}
to the environment, while .MAKEOVERRIDES= will disable export of VAR_CMD's.
From Var_Set: We actually want the equivalent of
.MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'
clearing the previous value for name is important, since
doing simple duplicate suppression does not handle:
$ make FOO=goo
which then runs a sub-make with FOO=boo
the commands from that sub-make should see just FOO=boo.
via MAKEFLAGS. Instead of appending them directly to .MAKEFLAGS, put
them in .MAKEOVERRIDES (and ensure they are quoted). This is now done
in Var_Set when it exports VAR_CMD's.
Use ExportMAKEFLAGS() to export MAKEFLAGS, using the combined content
of .MAKEFLAGS and .MAKEOVERRIDES (with duplicate supression).
If .MAKEFLAGS is assigned to in a Makefile, ExportMAKEFLAGS is called again.
This allows a line like:
.MAKEOVERRIDES=
to effectively stop the exporting of the command line vars in MAKEFLAGS.
1. make -dx turns on DEBUG_SHELL which causes sh -x to be used where
possible.
2. PrintOnError() is now called when make is stopping due to an error.
This routine reports the curdir and the value of any variables listed
in MAKE_PRINT_VAR_ON_ERROR.
3. Variables set via command line, are propagated to child-makes via
MAKEFLAGS. This behaviour appears to be necessary for POSIX (according
to the GNU folk anyway).
4. Do not reset MAKEFILE when reading ".depend" as this rather eliminates the
usefulness of ${MAKEFILE}.
5. Added ${.newline} as a simple means of being able to include \n in the
result of a :@ loop expansion.
6. Set ${MAKE_VERSION} if defined. Need to come up with a useful value.

actually read already. Albeit it's not damaging to copy zero data
for bufend == crec->data case, the buffer end could also be between
memory position 'crec' and 'crec->data'. Thus, we could end up with
negative 'bufend - crec->data' value, and obvious havoc.
This change fixes lib/12673, though the problem was masked and no longer
repeatable with the provided example after the recent buffer size bump.
The change was tested with the buffer size change backed off, and really
fixes the problem in the PR.
if needed and record count is within bounds (<MAXNUM), rather than
sorting the input by 64KB chunks. This cuts the number of needed
temporary files considerably (and improves performance, too).
Slighly adjust some #defines, mostly to power of 2 values.
This addresses bin/12673 and bin/12614, as well as complains from other
people.
Bug reported privately by Nicolas Ollinger <nollinge@ens-lyon.fr>.
You can trigger this bug prior to updating your sources with for example:
% cat > Makefile <<EOF
.DEFAULT:
a
EOF
% make
- 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.
For some reason this program wants to open _hundreds_ of temporary files.
Make it setrlimit(RLIMIT_NOFILE, ...), so this rather dubious strategy at
least works well enough to ctag(1) our own kernel.
