We cannot get IMAGE_OUTPATH from the build.log, and there is currently
no other mechanism. Creating a CHECK directory was a bad idea. It should
have been created only for CHECK, but it was always created when DEBUG
was not enabled. So it's better to just issue a warning.
Wrote that it's a bashism myself and neglected
to specify the proper shell, sigh.
This SHELL manipulation could ruin tracing
piggybacked onto it within lib/report.mk
but it's too late at this stage anyways.
The first half of both pipes was clearly a copy-pasted
initial logfile processing; the file can be of considerable
size (e.g. several megabytes) so it might be slightly more
efficient and cool (but a bit more arcane) to use bash(1)'s
process substitution along with good ol' tee(1) like this:
$ echo -e '1\n2\n3' |tee /dev/stderr 2> >(grep 2 >STDERR) |grep 1 >STDOUT
$ head STD*
==> STDERR <==
2
==> STDOUT <==
1
That "clever hack" with two rev(1) invocations
seems pretty stupid to me: too much processes
and processing instead of simple prefix removal.
One can also have that as ${var##*/} when dealing
with a shell variable and avoiding extra forks, BTW.
Make it uniform through a function -- with the initially desired effect
of no extra lines while building multiple images with REPORT=1
(those were useless anyways printing repeatedly the same path
that's relative to a particular builddir).
Sometimes REPORT=1 just wasn't passed to make, and the build.log
saved is noisy and harder to compare through diff(1); let's move
the implementation out of the makefile and into a standalone
script so it can be reused like this:
BUILDDIR=$(sed -rn "s/^mki-image-scripts: export GLOBAL_BUILDDIR='(.*)'$/\1/p" build/build.log
bin/cleanlog < build/build.log > build/reports/clean.log
See "export GLOBAL_BUILDDIR=" line in the particular log
(grabbing that one from stdin is not exactly trivial though).
"Provide iso contents file" has been a long-standing
feature request regarding both starterkits and distros
proper; release managers used to compensate this with
their own scripts.

This is a mild generalization of what has been done by hand
to figure out a problem with make-initrd-propagator-0.10-alt1:
stripping anything intrinsically volatile off the build.log.
The filter set isn't perfect, and the proper logging will
involve mkimage tweaks as well (e.g., one generally isn't
interested in instrumental chroots' population that much,
so it should only be verbose at the higher debug levels).
It's hard to tell a successful build from a failed one
if downstream hides the exit code; it's useless to continue
a `for' loop if a pipe shoves that to a subshell; well it seems
that a bashism is worth a thousand quirks with extra fds here.
Minor regexp enhancements are also due.
reports.mk made a bit more resilient/prudent either.
Following m-p-d, a more involved default output directory
structure is feasible now:
~/out/name/date/name-date-arch.type
instead of plain
~/out/name-date-arch.type
This particular behaviour can be achieved by passing
SORTDIR='$(IMAGE_NAME)/$(DATE)'; note the single quotes.
Reports are also saved in this resulting structure
albeit the place is still highly debatable.
The purpose is being able to examine particular target interdependency
graph for a given image having been configured to avoid convoluted
dependencies (loops in particular).
The implementation is based on SHELL hook hint by John Graham-Cumming:
