If all cores are used, it should be set to 0, which will use nproc
after the cpuset has been defined, and not nproc (which is the number
of cores/threads on the machine).
Previously, the "update" target was just added to the end of
the "all" target prerequisites, so that it was run at the end.
But now, we enter make with some -j value in MAKEFLAGS, so that
the "update" target may well be run before the other targets, which
is wrong: for example if it is run before the "xxx-z-libxslt" target,
xsltproc is not found and the update target fails.
To fix, define "update" as the default target, and have it depend
on "all".
When using "sh << EOF", what is between this line and EOF runs
with no attached terminal. But we need a terminal for running the
build. So we have to use "sh -c ". But then nesting of double
quotes, $, etc is too complicated. So run as root, and become back
user only when exec'ing. For some reason $@ does not work, so use
a variable set to $@.
Still WIP but some progress...
When moving a shell to a cgroup not associated with a session,
then subsequent calls to pam_systemd or pam_elogind create
a new session, and a new cgroup for that session, so that the
cgroup of the calling process is not used (this is a problem
with both systemd and elogind). For systemd, the problem can be
solved by passing --slice <user slice> to systemd-run. For elogind,
we need to first move the shell to a non session cgroup, then run
sudo so that a new session is created, then pass the cpuset to that
session's cgroup. Hopefully, if neither systemd nor elgind is used,
then the former solution should work (to be tested!!!).
If using a new book, MAKEFLAGS is set to -j$(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 $(nproc) if using all cores, so don't replace it in
the comment-test template (otherwise we have infinite recursion).
- Put parallelization menu first
- Fix the logic for variable definitions in this menu
- change jhalfs to reflect the separation of optimization and
parallelization
- validate new variables
- remove MAKEFLAGS from the validation of optimize variables
- also remove the black list, which has not been used in years.
Those scripts could only be run once, because mount errors out
if it tries to mount an already mounted fs (or unmount a non
mounted fs). This changes generation of the scripts so that
any mount is preceded with "mountpoint -q || ", and any umount
is preceded with "mountpoint -q && ".
When not downloading packages, the function "get_sources" returns
early because it begins with:
[ "$GETPKG" = y ] || return
The problem is that in this case it returns with an exit code
inherited from the last executed instruction, which is the
test (and therefore "false"). The solution is to change to
return 0.
- update versions and instructions in packageManager.xml.pacman.
Also remove the pages for old books.
- Fix packInstall.sh.pacman, so that restarting after a failure
is possible
- Change LFS/lfs.xsl so that destdir install use symlinks for
/lib, /sbin, and /bin. Remove also absolete commands for old
books
- fix gcc script in book parser
Also fix typos and shell programming. Use "cat file | while read"
instead of a complicated construct for reading only lines and then
breaking lines into their fields... Fix a TODO item
Now that we have only lfs, some lines in the Makefile have been
removed, but still some shell continuation (&& \) were left. This
leads to weird error message (@ non existing command, or so).
Remove the continuation characters.
- do not try to copy downloaded files to $SRC_ARCHIVE: they may
belong to another user, and so be non writable.
- trunk/BOOK is not used anymore in BLFS/Makefile
- do not make update a second time
- If MISSING_FILES.DMP is left from a preceding attempt, it may
generate a false warning a bout missing files even if they could
all be downloaded.
- do not try to copy a modified file to SRC_ARCHIVE if it already
exists: it may belong to another user...
- Check that there is enough material to calculate a SBU (!)
- Prevent an error if REALSBU does not occur in jhalfs.config
- Remove double square bracket: they change semantics and
I cannot memorize what the change is (but e.g. file* is not
expanded even if there is some filexxx in the dir).
The tracking file is needed for gen_pkg_book.sh as a first argument.
Since it is called to generate the initial scriptlets, it needs
to be passed the full path of the tracking file, including
$BUILD_DIR. The $TOPDIR is now the second argument (and still
needs to be passed too).
Now gen_pkf_book.sh depends on trackfile. This can be passed
as an argument, but to ease calling it standalone, we need to
set the default to the actual file used.
This is an oversight of when we moved to profiling and when we
removed the docbook xsl stylesheets from the LFS directory.
Docbook XML DTD and XSL stylesheets are needed, so test them
at start. This has the effect of removing the need for check_blfs_tools.
When running git-version.sh, unconditionally add a $INITSYS
argument, which is needed for the new condxml, and
is harmless if this argument is not needed.
