2019-08-09makechrootpkg: with -n, check if the package failed to installEli Schwartz
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. Add a check for how many split Signed-off-by: Levente Polyak <anthraxx@archlinux.org>
2019-08-09makechrootpkg: make the -U option work for the first time everEli Schwartz
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". Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Levente Polyak <anthraxx@archlinux.org>
2019-08-09makechrootpkg: also downgrade packages when updating chrootsEli Schwartz
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!

2019-08-09makechrootpkg: when installing with -I, ensure package is installedEli Schwartz
noconfirm is wrong here, as we don't want to accept the default answer -- we want to install the new package, even if it conflicts and provides an existing one. After all, we explicitly asked for it.

2019-08-09makechrootpkg: accept arguments useful to verifysourceEli Schwartz

2019-08-09makechrootpkg: fix breakage in makepkg option parsingEli Schwartz
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. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Levente Polyak <anthraxx@archlinux.org>
2019-08-09Escape paths with ":" that are passed to systemd-nspawn --bindEli Schwartz
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.

2019-08-09makechrootpkg: check truthiness using shell arithmeticEli Schwartz
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. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Levente Polyak <anthraxx@archlinux.org>
2019-08-09Revert "makechrootpkg: Have functions be more function-y."Eli Schwartz
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 Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Levente Polyak <anthraxx@archlinux.org>
2019-08-09Revert "makechrootpkg: Avoid having code floating around outside of a function."Eli Schwartz
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. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Levente Polyak <anthraxx@archlinux.org>

2019-06-12Revert "makechrootpkg: sync_chroot: Make more general."Eli Schwartz via arch-projects
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. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org>
2019-03-25makechrootpkg: keep *DEST, MAKEFLAGS & PACKAGERMatt Robinson
If makechrootpkg is called as non-root, the {SRC,SRCPKG,PKG,LOG}DEST, MAKEFLAGS and PACKAGER environment variables are lost in the call to check_root(). Add these to the passed keepenv list so that they are preserved instead.
2019-01-22remove empty tree if "--verifysource" failedErich Eckner
makechrootpkg's download_sources() leaves a stray directory if "makepkg --verifysource" failed. We use "setup_workdir" instead of "mktemp -d", because this ensures the correct garbage collection. Signed-off-by: Erich Eckner <git@eckner.net>
2018-05-31makechrootpkg: whitelist return code 14 from makepkgEli Schwartz via arch-projects
makepkg 5.1 implements error codes, and 14 means that installing the packages after they were built has failed. We don't care about this error and would like makechrootpkg to succeed regardless, e.g. for split packages that are mutually exclusive. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org>

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.
2018-05-13makechrootpkg: Do not copy the user keyring into the chroot.Eli Schwartz
Since commit 75fdff1811a0487f82c75b2e260da905102b4eea we no longer run integrity checks inside the chroot anyway, so this is no longer needed and will never be used.

2018-03-24makechrootpkg: fix verifysource with pacman-gitEli Schwartz
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.)

2018-03-24makechrootpkg: respect GNUPGHOMEEmiel Wiedijk

2018-01-21makechrootpkg: Fix anti-pattern when checking for enabled featuresEli Schwartz
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).

2018-01-21makechrootpkg: Fix unconditionally running namcapEli Schwartz
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. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org>

2017-10-30makechrootpkg: Fix function usage commentsLuke Shumaker
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").
2017-10-30makechrootpkg: move init_variables() to be part of main()Luke Shumaker
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().
2017-09-14makechrootpkg: Reopen console to assign the CTTYJan Alexander Steffens (heftig)
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.
2017-09-14makechrootpkg: Prevent collecting coredumpsJan Alexander Steffens (heftig)
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.

2017-07-05makechrootpkg: Fix broken symlinks because of chroot SRCPKGDEST /srcpkgdestLuke Shumaker
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.
2017-07-05makechroot: download_sources: Accept makepkg_owner as an argumentLuke Shumaker
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.
2017-07-05makechrootpkg: sync_chroot: Make more general.Luke Shumaker
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 "$source/.." is on btrfs; the root could be a directly-mounted subvolume, but and the destination could be another subvolume of the same btrfs mounted somewhere else. The things we do care about are: - The source is a btrfs subvolume (so that we can snapshot it) - The source is on the same filesystem as the directory that the copy will be created in. - If the destination exists: * that it is not a mountpoint (so that we can delete and recreate it) * that it is a btrfs subvolume (so that we can quickly delete it) On the last point, it isn't necessary for creating the new snapshot, just for quick deletion. That can be a separate check, where we use regular `rm` for deleting the existing copy, but use subvolume snapshots for creating the new one.
2017-07-05makechrootpkg: sync_chroot: make usage easier to understand.Luke Shumaker
Also, shorten the "Synchronizing" message to only include the full path to the copy if it was specified. The capslocked variable names in the Usage comment were references to things in Parabola's tools, that didn't make much sense here out of context.
2017-07-05makechrootpkg: delete_chroot: Fix the is-btrfs-subvolume check.Luke Shumaker
First of all, it ran `is_btrfs "$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. https://lists.archlinux.org/pipermail/arch-projects/2013-September/003901.html
2017-04-17makechrootpkg: Avoid having code floating around outside of a function.Luke Shumaker
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.

2017-04-05makechrootpkg: Improve status messages.Luke Shumaker
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.
2017-04-05makechrootpkg: Adjust to have the functions work with `set -u`.Luke Shumaker
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`.
