Use pacman's --dbpath feature to sync fresh databases inside an isolated
location and split up the database sync and package location calls to
remove the need of weird grep calls.
It isn't nice of makechrootpkg to modify the host database state just by
building packages. No foreign program shall automatically modify
the host database other than by the explicit will of a system
maintainer, which is the major reason this changes get incorporated.
However, there is certain indoctrinated believe that using -Sy is
the prime evil. In fact it has been declared as a social rule to a
technical problem of not getting into potential partial upgrade states.
This is not a proper loophole less solution as there are multiple ways
and use cases that lead to such a state, like aborting a -Syu on the
prompt for whatever reason, what really matters is that it is not a
technically bullet proof solution to solve the problem.
Databases shall have the freedom to be as up to date as databases or
their owner wishes, allowing querying on latest database state without
fear. The only loophole-less contract that _really_ is from importance
is always using -Su instead of plain -S to install packages. Installing
packages is what actually brings one into a potential partial upgrade
state and by using -Su an outstanding upgrade is forced when installing
a new package. This properly solves all edge cases in a technical
manner instead of declaring people who abort the prompt of -Syu to be
the problem. In fact, using this simple contract allows whatever system
maintenance workflow a host owner wants to follow, which may still be to
always use -Syu and deal with system upgrades explicitly instead of the
time when installing new packages, but the -Su contract is the real safe
guard to guarantee no edge case can ever slip in. This magically also
opens up the freedom to people who wish to use -Sy to simply query on up
to date data as the currently indoctrinated "never do -Sy" stone plates
not only are not rock solid in technical terms but also make certain use
cases simply impossible and hence cripple the functionality without at
the very least being fully loophole free.

Avoid re-splitting remotepkg elements used for checkpkg conditions.
|
|
For build servers or similar infrastructure its relatively common to not
sync/update the database regularly. This leads to problems properly
running checkpkg duo to nonexistent target files that we try to
download. As building on build servers is a very common use case, lets
ensure we sync the local database before trying to resolve the package
locations.
|
|
Avoid always trying to download and output the according message.
Add checks for packages either not being available in the repo or
all variants have up to date versions stored in the local cache.

Sometimes its desired to be explicitly made aware of differences
reporter by checkpkg via printing a warning instead of a regular
message.
Automatically use --warn for makechrootpkg builds so packagers are made
visibly aware of a soname bump by simply looking out for colors
indicating non success messages.

In some cases, like default makechrootpkg execution, the temporary

This reverts commit be44b9cde15f3228839253c0c0d7d56c124c4e26.
This was a nice idea in theory, because it means that we can catch
conflicting files before releasing them into the repos. In practice,
there were unanticipated side effects: single-package installs which
conflict against their own makedepends cannot be installed either.
Examples include:
- kernel modules which makedepend on their dkms equivalent
- jack2, which makedepends/optdepends on portaudio, which requires
jack... but jack2 is a drop-in provides/conflicts jack.
We cannot reliably detect when makepkg --install will error out because
of dependency conflicts vs. packages which are simply broken. So, back
out this change for now.
Revisit this once pacutils has a new release, because it will add the
option --resolve-conflicts=all, allowing for much better scripted
responses to "foo conflicts with bar, remove bar? [y/N]" than simply
"--noconfirm and fail".

We previously whitelisted this return code because split packages can
frequently conflict each other, so makepkg -i is *expected* to fail in
such a case. However, there is no good reason to let this succeed if the
pkgbase only builds one pkgname -- that will always be a severe issue.

The -U option was initially introduced in commit
cda9cf436b2897b063c1e40efb144404aad8b821 in order to enable running
makechrootpkg as root, delegating to another, manually selected, user to
perform various non-root tasks (given that makepkg was modified to throw
fatal errors when run as root without the option of --asroot to disable
that). However, it was only ever implemented for the --verifysource
option outside of the chroot, and the builduser inside the chroot is
created with the same uid as the makechrootpkg invoker. It needs to run
as the same uid, because it needs rw access to $startdir and $SRCDEST!
Additionally this lets the invoking user more easily inspect the build
directory in case of problems...
The correct solution for this is to properly implement the initial
intention of the -U option, and make it override the autodetection of
the "invoking user" which is normally done by inspecting $SUDO_USER.
This is then used as the single source of truth for "who am I pretending
to be".

Packages should never be getting downgraded... unless a package is
pulled from testing, e.g. for example if gcc9 totally breaks the linux
kernel. In such cases, the master repo says there is a downgrade, so
we'd better go with that. Basically, ensure that packages match the repo
they are being built against. Consistency at all costs!

In commit bd826752c9dc8f01917ee831302b6220ad09603a, support for short
options was added to the heuristic for --noextract, but in the process,
we changed to loop over the set of user options plus the builtin
defaults for inside the chroot. This was wrong, as we only care about
the user options -- moreover, it prevents us from adding verifysource
support *outside* the chroot, for options that are also chroot options,
like --holdver.
Also remove uselessly duplicated line.

When parsing paths to automatically make available to the container, the
":" is used internally by systemd-nspawn to signify destinations in the
container. Replace automatically with "\:" for the mounts that we set
up, in order to safely handle a working directory etc. that contains
this character.
For bind options exposed to the user, it is assumed the user takes care
of passing systemd-nspawn compatible paths themselves.

Using the literal strings "true" and "false" is inaccurate and may
result in uncertainty of whether it is set when doing string comparison,
or simply rely on the shell implementation of treating the string as a
command builtin, then executing the value as a shell command. Emulate
makepkg, which makes heavy use of shell arithmetic for this purpose.

This reverts (the bulk of) commit 2fd5931a8c67289a8a4acd327b3ce99a5d64c8c7.
Reducing globals makes little sense in in a oneshot bash script, but
reduces code clarity and in fact resulted in bugs because even the
commit author couldn't keep track of the script state.
An exit was changed to a return, even though that made no sense outside
of a function, and has been duly returned to being an exit. This was
never tested and later papered over by wrapping the entire script in a
main() function and then calling the function for hysterical raisins.
The functiony nature of sync_chroot/delete_chroot is preserved, as those
functions demonstrate meaningfully standalone functionality -- who
knows? we may want to reuse this. Everything else is tightly bound to
the internal logic of makechrootpkg.
Completely separate functionality that was silently implemented in the
original commit is also preserved:
- declare a couple of variables as locals
- move the abort-on-no-PKGBUILD outside the install_packages function

This reverts commit 49088b0860276c664933c2b3e36a2fef714b7a07.
The fundamental intention was flawed and broken, it caused annoying
issues and regressions, and the self-avowed sole purpose of the change
was so that a downstream project could *post-modify the script and
source it as a library*.
That is not okay. You don't wrap non-factorable code in a function
called main() and call it a library. The only possible use for this is
to treat makechrootpkg *internals* as a library, which is not supported.
Downstream projects that wish to use the functionality of makechrootpkg
should treat makepkg as a command with a public API in the form of
command line options. That is kind of how commands of all kinds work,
since forever. That is how all users of makechrootpkg *except for
parabola* use it.
Arguments that "it saves us the cost of fork+exec to bash" are simply
invalid.

This reverts commit 6d1992909cc46e293027ff488ae2632047603e66.
It has never worked. In commit c86823a2d4a4152c71faa1c3bab227756232996f
it was noted that it compared the device numbers for [[ $1 = $1 ]] which
was a useless check and always returned true, for *any* btrfs
filesystem. Now that the function is corrected to compare [[ $1 = $2 ]]
the check is still useless, but this time because it always returns
false -- btrfs subvolumes on the same filesystem do *not* share device
numbers.
So let's go back to the original working implementation that only
matters in terms of makechrootpkg, and just checks if makechrootpkg's
root working directory is btrfs (in which case we know it will be a
subvolume because mkarchroot will create it that way).
This restores our special support for the btrfs filesystem.

chown support "$user:$group" but also "$user:" which infers $group
rather than leaving it as root. This looks up the group name in cases
where the default group is e.g. "users" and users do not get their own
unique groups.

Since commit 75fdff1811a0487f82c75b2e260da905102b4eea we no longer run

In pacman-git commit d8717a6a9666ec80c8645d190d6f9c7ab73084ac makepkg
started checking that the setuid/setgid bit could be removed on the
$BUILDDIR in order to prevent this propagating to the packages
themselves. Unfortunately, this requires the temporary builddir used
during the --verifysource stage of makepkg, to be owned by $makepkg_user
which was not the case as it is created as root using mktemp (and given
world rwx in addition to the restricted deletion bit.)
Obviously makepkg cannot chmod a directory that it does not own. Fix
this by making $makepkg_user the owner of that directory, as should have
been the case all along.
(Giving world rwx is illogical on general principle. The fact that this
is a workaround for makepkg demanding these directories be writable even
when they are not going to be used for the makepkg options in question,
is not justification for being careless.)

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 2fd5931a8c67289a8a4acd327b3ce99a5d64c8c7
$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.

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.

Slightly more verbose, but also more understandable.

download_sources(), while the first invocation of makepkg, is a rather
odd place for this kind of guard.
|
|
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 added PKGBUILD.proto file is so that shellcheck can know know what
to expect that a PKGBUILD sets.
|
|
These changes are all strictly "slap some double-quotes in there".
Anything more than that is not included in this commit.
|
|
These are purely stylistic changes that make shellcheck complain less.
This does NOT include things like quoting currently unquoted variables.

|
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.
