Still WIP but some progress...
When moving a shell to a cgroup not associated with a session,
then subsequent calls to pam_systemd or pam_elogind create
a new session, and a new cgroup for that session, so that the
cgroup of the calling process is not used (this is a problem
with both systemd and elogind). For systemd, the problem can be
solved by passing --slice <user slice> to systemd-run. For elogind,
we need to first move the shell to a non session cgroup, then run
sudo so that a new session is created, then pass the cpuset to that
session's cgroup. Hopefully, if neither systemd nor elgind is used,
then the former solution should work (to be tested!!!).
If using a new book, MAKEFLAGS is set to -j$(nproc), so that if
we want to easure timings with 4 processors and our computer has
more than that, we need to restrict the number of processors.
Jhalfs allows to do that using th cpuset cgroup controller, so that
it only restrits the make job and not the whole machine. For that
use a small scripts written by Xi Ruoyao that restarts make this
the cpuset set.
There is no more $(nproc || echo 1). Note that we may replace
it with $(nproc) if using all cores, so don't replace it in
the comment-test template (otherwise we have infinite recursion).
- Put parallelization menu first
- Fix the logic for variable definitions in this menu
- change jhalfs to reflect the separation of optimization and
parallelization
- validate new variables
- remove MAKEFLAGS from the validation of optimize variables
- also remove the black list, which has not been used in years.
Our gen-special.sh transforms a dependency on compound packages
(xorg7-*) on a dependency on the list of packages. This generates
a lot of trials when removing circular dependencies, because if the
dependency on xorg7-* is optional, all packages in the list are tried
in turn, while it is sure that anyway the dependecy must be eliminated.
If the dependency is only on the last package, the circular dep
is eliminated at first try.
If the shell exits with an error, teardown is not run in target
chroot, which may lead to unwanted effects, such as preventing
unmounting the $BUILD_DIR. Tell make to ignore the error.
Now that devices.sh can be run even if the fs are already mounted
all the targets after mounting the virtual kernel fs can depend
on "devices". This way, if for some reason a partial build is
restarted after a reboot, the virtual kernel fs are automatically
re-mounted.
Fixes#1737
Those scripts could only be run once, because mount errors out
if it tries to mount an already mounted fs (or unmount a non
mounted fs). This changes generation of the scripts so that
any mount is preceded with "mountpoint -q || ", and any umount
is preceded with "mountpoint -q && ".
If the kernel-config file is not up to date (missing options or
whatever), the kernel "make" will hang, waiting for input. So
run "make oldconfig" explicitly, with a timeout.
Fixes: #1736
gen-special.sh uses the list of files and md5 from the
cat instructions to generate an xml page for each of
the individual components. Until now, there were no commented
out component, so gen-special.sh was not prepared to handle
comments. Now, it removes lines containing comments.
We use grep -l ^"${otherlink[*]"\$ to find parentNode, since the
parentNode is the only file with a link line that matches. Problem
is that sometimes the priority line may match too. This makes a
parentNode variable containing several lines, and when redirecting
to $parentNode, creates those "ambiguous redirect" messages.
Fix: use a loop, and only grep on the first line of each file.
Add several packages that shouldn't be removed when doing dependency
checking, two of which are actually not in lfs, but needed for
script: porg tzdata sudo wget
Add an XSL stylesheet for listing packages in LFS. Those are
not listed anywhere else, but they are considered dependencies of
everything, so should never be erased.
For outputting DESTDIR=, we need to test whether the text contains
"make". But when it contains "qmake" (or any different word containing
"make" but not exactly "make), we don't want to output anything more
than the text. So strengthen the test.
We output text()[1], literal (literally), text(2). This does
not work if there are several <literal> tags. Change it to
outputing preceding-sibling::text()[1], literal for each
literal tag, then output text()[last()] (which works also
when there are no literal tag, so it removes a choose.
For additional downloads, the normal book layout is a <bridgehead>
containing "Additional Downloads" followed by one or more
<itemizedlist>, one for each file to download. But on some pages,
there are several <bridgehead>, each followed by one or more
<itemizedlist>. So we have to check that only the <itemizedlist>
correponding to the current <bridgehead> are treated. Otherwise,
the download code may be generated more than once. This imposes
that no other bridgehead is inserted between the one containing
"Additional" (or in some case "Recommended/Optional Download") and
the <itemizedlist>.
Instead of having them inside the Makefile, which implies editing
them (automatically), which is not robust if anything changes:
it got broken when a test for a mountpoint was added...
Presently, when the <node>groupxx file is created, we copy "a"
lines from <node> to <node>groupxx (changing "a" to "b") and
we remove all the lines containing the runtime dependency from
<node>. This may not always be what we want: for example, a
dependency can be both "required at runtime" and "optional for
tests". We should keep this information when cleaning the nodes.
Only when removing circular paths should the optional tie be broken
if necessary.
