Don't use error-prone logic e.g.
foo=true; if $foo ...
This completely fails to act as expected when the variable is unset
because of unrelated bugs.
While this merely causes the default behavior to be "false" rather than
"true" in such cases, it is better to fail to enable explicitly
requested behavior (which will be noticed by the user) than to simply
upgrade to this behavior for free (which may not seem to have any
obvious cause).

Fixes regression in 2fd5931a8c
$run_namcap will always be set to ""
`if $not_a_var; then ...; fi` is always truthful when $not_a_var is
unset or equal to "" and the `then` clause will always be run.
I'm not sure why global state variables need to be cloned locally for
their sole explicit purpose.
But for now this patch implements the minimum necessary work to properly
pass the "do I want namcap" variable into prepare_chroot() according to
the current logic flow.
Note that I have still not thorougly tested makechrootpkg.

Recent development versions of makepkg support reproducible builds
through the environment variable SOURCE_DATE_EPOCH. Pass this variable
through makechrootpkg to makepkg when available.
Also initialize SOURCE_DATE_EPOCH whenever running archbuild to enforce
reproducible builds for repository packages.

A couple of the comments noting which globals are used by functions are
outdated/wrong.
- download_sources() : Remove USER from the list. It was always wrong.
Originally, it should have been SUDO_USER (not USER), but I should have
removed it entirely in 4f23609.
- move_products() : Add SRCPKGDEST to the list. Though the commit adding
the comment was only recently upstreamed (as 2fd5931), it originated in
2013 in a commit that has since been rebased many times. Anyway, in
this rebasing, it missed move_products() starting to pay attention to
SRCPKGDEST in fd1be1b (since nothing made git think there was a
"conflict").
The reason it wasn't moved before was just to keep the diffs
(with --ignore-all-space) smaller, to make merging and rebasing work
easier. Moving code around in a file tends to make that difficult.
But, readability wise, it belongs in main().
nspawn does not give us a controlling terminal, hence we ignore
interrupts. Apparently this was lost in systemd at some point.
Hack around this by reopening the console to make it the controlling
terminal.
Coredumps from build chroots are not generally useful. Prevent
them from being generated.
Avoids a lot of annoyance from the GCC testsuite spawning lots of
systemd-coredump processes.
Just set the soft limit so the user can still raise it in the PKGBUILD
if they insist.
Commit 58968cf fixed symlinks for package products in $startdir in
light of the simplified chroot setup. However, a similar change needs
to be made for source-package products. This was an easy omission to
make because makechrootpkg does not produce source-pakcages by
default.
The bug isn't currently triggered, but I accidentally did trigger when I
was trying to modify the command a bit. I figure a "caution" sign would be
helpful to any future developers.
What this is really doing is fixing a conflict that I had incorrectly
resolved when rebasing what became 2fd5931 onto cda9cf4. Of course,
because of dynamic scoping, everything worked out, and everything worked as
intended.
Before cda9cf4, it was appropriate for download_sources to take src_owner
as an argument, but after cda9cf4, it is now appropriate to take
makepkg_user as an argument. However, it still takes src_owner as an
argument, but pays 0 attention to it; instead looking at makepkg_user which
it happily inherited because of dynamic scoping.
So change it to take makepkg_user as the argument.
This is inspired by the thought that went in to the delete_chroot
is_subvolume commit.
sync_chroot($chrootdir, $copydir) copies `$chrootdir/root` to `$copydir`.
That seems a little silly; why do we care about "$chrootdir"? Have it just
be sync_chroot(source, destination) like every other sync/copy command.
Where this becomes tricky is check to decide if we are going to use btrfs
subvolumes or not. We don't care if "$source/.." is on btrfs; the root
could be a directly-mounted subvolume, but and the destination could be
another subvolume of the same btrfs mounted somewhere else.
The things we do care about are:
- The source is a btrfs subvolume (so that we can snapshot it)
- The source is on the same filesystem as the directory that the copy will
be created in.
- If the destination exists:
* that it is not a mountpoint (so that we can delete and recreate it)
* that it is a btrfs subvolume (so that we can quickly delete it)
On the last point, it isn't necessary for creating the new snapshot, just
for quick deletion. That can be a separate check, where we use regular
`rm` for deleting the existing copy, but use subvolume snapshots for
creating the new one.
Also, shorten the "Synchronizing" message to only include the full path
to the copy if it was specified.
The capslocked variable names in the Usage comment were references to
things in Parabola's tools, that didn't make much sense here out of
context.
First of all, it ran `is_btrfs "$chrootdir"` to decide if it was on
btrfs, but $chrootdir wasn't defined locally; it just happens to work
because $chrootdir was defined in main(). (I noticed this because in
Parabola, it is called differently, so $chrootdir was empty).
So I was tempted to just change it to `is_btrfs "$copydir"`, but if
$copydir is just a regular directory on a btrfs filesystem, then it
It would leave much of $copydir intact. What we really care about is
if $copydir is a btrfs subvolume; which we can check by combining the
is_btrfs check with inspecting the inum of the directory.
I put this combined check in lib/archroot.sh:is_subvolume.

This means wrapping variable initialization in init_variables(), and the
main program routine in main().
I did NOT put `shopt -s nullglob` in to a function.
It make make sense to move init_variables() down into the main()
function, instead of having it as a separate function up top (if this
done, then the `-g` flag passed to `declare` in init_variables() can
be dropped). However, in interest of keeping the `diff -w` small, and
merges/rebases simpler, this isn't done here.
In sync_chroot(), this makes the messages be a bit more precise with
exactly which thing they are syncing where. This is based on my users
expressing confusion at what is going on (especially when something is
taking a long time, and they have to blame something for blocking).
With these changes, I haven't gotten such confusion in a long time
(but maybe my users just got used to it).
In delete_chroot(), this changes "temporary copy" to "chroot copy",
since in Parabola's version of the tools, the function can get called
from other places, and it isn't necessarily operating on a temporary
copy.
Even though main() doesn't call `set -u`; this way the functions will
continue to work if copied into an environment with `set -u`, or so
that we are ready if we ever want to start using `set -u`.
Rather than them simply being named blocks of code with braces around
them.
That is: have them take things via arguments rather than global
variables.
Specific notes:
- create_chroot->sync_chroot:
I pulled out locking the destination chroot; getting that lock is
now the caller's responsibility. It still handles locking the
source chroot though.
I pulled the `if [[ ! -d $copydir ]] || $clean_first;` check out; it is
now the caller's responsibility to use that check when deciding if to
call sync_chroot.
However, when pulling that check out, I left it as `if true;`, to
keep an indentation level. This patch has had to be rebased/merged
many times, and changing the indentation is a sure way to make that
go less smoothly; I'm not going to re-indent this block until I see
the check removed in the git.archlinux.org/devtools.git repository.
- install_packages:
1. Receive the list of packages as arguments, rather than a global
variable.
2. Make the caller responsible for looking at PKGBUILD. From the
name and arguments, one would never expect it to look at PKGBUILD.
It was displaing the value of the `makepkg_args` variable, which may
have already been changed by the argument parsing by the time it gets
to `-h`. Now there is a separate `default_makepkg_args` variable.
This involves extending the signature of lib/common.sh's `stat_busy()`,
`lock()`, and `slock()`. The `mesg=$1; shift` in stat_busy even suggests
that this is what was originally intended from it.
In cases where there is no license specified, the file is tagged as
"License: Unspecified". Obviously, that is not ideal, but it
highlights the fact, and I hope that it encourages whoever has the
authority to specify the license to do so.
On that note, to anyone who may have the authority to specify the
license of files in devtools: the current licence of many files is
GPLv2 with no option for later versions; I impore you to re-license
them to have the "or any later version" option.
`lock_close FD` is easier to remember than 'exec FD>&-`; and is especially
easier if FD is a variable (though that isn't actually taken advantage of
here).
This uses Bash 4.1+ `exec {var}>&-`, rather than the clunkier
`eval exec "$var>&-"` that was necessary in older versions of Bash.
Thanks to Dave Reisner for pointing this new bit of syntax out to me
the last time I submitted this (back in 2014, 4.1 had just come out).
The systemd package creates a subvolume at /var/lib/machines (through
tmpfiles), if it can. We need to delete this subvolume before we can
delete the parent subvolume.
Look through the root for inodes with the number 256. These identify
subvolume roots.
The way in which makechrootpkg reads variables from makepkg.conf(5) is
different from makepkg, in that it reads a subset of defined
variables, and only if the were not set in the environment before.
Mention this in the usage text.
Fixes FS#44827
This removes the preservation of HOME being /build just for the pacman
sudo call. Former leads to unbuildable packages when an to be installed
dependency writes something into the HOME dir (f.e. .config). The
resulting directories won't be writable by the builduser as they are
owned by root:root and ultimately will fail to build anything that
requires so.
The gnustep-base package ships a profile.d script that adds
"$HOME/GNUstep/Tools" to the PATH, which breaks when the user changes
and causes meson to exit with a "permission denied" error.
Copy both UID and primary GID of the invoker to the builduser. Mount
srcdest and startdir read-write.
v2: Fixed GnuPG keyring owner and moved running namcap from a heredoc
to a function.
This way the HOME dir is writable and no ugly hacks are required
in the PKGBUILD if $HOME is accessed (f.e. maven, gradle and also
some python tests etc.)
