ProteanOS Development Kit version 3.0.0
---------------------------------------
Released: ????-??-??
This new major version of prokit has been in development since
2020-06-22. Notable new features in this release include unified
installers (the separate "prokit installer-pc" and "prokit mkinitramfs"
being merged into "prokit install"), "prokit build" saving detailed
build logs, and the use of package archive section feeds.
New features:
* "prokit install" is now a frontend for all installers. The separate
"prokit installer-pc" and "prokit mkinitramfs" commands have been
removed and merged into "prokit install", which determines which
backend to use for a requested platform. The "pcramfs" backend now
installs a system and packs it into a RAM-based file system, all in
one command; it also removes all of the installed files that get
packed into the RAM-based file system.
* "prokit install" no longer supports installing to block devices
platforms that are intended to run under chroot (such as ProteanOS's
"dev" platform).
* "prokit install" now determines the correct architecture for a
requested platform. The "-a" option is now only necessary if
installing ProteanOS's "dev" platform for an architecture different
from but compatible with the native architecture.
* "prokit build" now passes an "-a" option, if supported, to opkg to
install host-architecture non-coinstallable dependencies (such as
library development packages) when cross building.
* Newly installed ProteanOS systems now have feeds for sections
"base", "boot", "lib", "share", and "util" listed in their opkg
configuration (previously only "base"). Systems of profile "dev"
additionally have "dev" and "libdev" section feeds. A "src" section
for architecture "src" and platform "all" has also been added. The
recommended way to add these section feeds to an existing system is
to install a new system of the same architecture and platform and
copy its opkg configuration into the old system.
* In the ProteanOS profile, the "base-files" and "config-base"
packages and their dependencies are installed. Previously, all
packages marked "Essential: yes" and their dependencies were
installed, which was a long-standing misuse of the "Essential"
field.
* "prokit build" now saves logs of builds and prints detailed
information about the build and its results.
* "C" and "POSIX" locales have been added. They are identical to the
"en_US" locale.
Error handling and bug fixes:
* "prokit shell", "prokit opkg", and "prokit build" now pass through
relevant exit statuses. "prokit build" also no longer tries to run
opkbuild after opkg exits with an error.
* If prokit received a signal while running a command under chroot, it
could have failed to unmount a file system on a block device. This
has been improved.
* An incompatibility with GNU Bash, Z shell, KornShell, MirBSD Korn
Shell, and possibly others (except Almquist shell derivatives DASH
and BusyBox ash) present since prokit version 2.0.0 has been fixed.
* Installation commands no longer assume that the "cut" utility is
usable within the root being installed. ProteanOS's busybox
1.32.0-1 manages "cut" and almost all other utility links using
update-alternatives, so they aren't usable until after installation.
* A potential infinite loop in the dependency solver has been fixed.
* The dependency solver now solves dependencies of packages whose
names contain ":" (such as coinstallable library development
packages in ProteanOS).
* The foreign installation service initialization script is now
scheduled to run before any other initialization scripts on a newly
installed system.
ProteanOS Development Kit version 2.0.1
---------------------------------------
Released: 2019-09-30
Bug fixes and minor changes:
* An expansion of an undefined variable in a function called during
"prokit build" has been fixed.
* opkg-cert (executed by "prokit install" and "prokit installer-pc")
no longer prints a wrong and confusing "Clock incorrect" message
after the "Invalid certificate" message when a mirror has an expired
certificate.
* "prokit install" and "prokit installer-pc" in the ProteanOS profile
now support FTP mirrors.
ProteanOS Development Kit version 2.0.0
---------------------------------------
Released: 2019-04-27
This major new release of prokit has been in development since
2014-10-13. Major new features include automatic block device mounting;
new "prokit installer-pc" and "prokit mkinitramfs" commands; downloading
and storing gzip-compressed package feed index files; verifying package
feed index file signatures against a validated archive certificate; and
fetching lists of ProteanOS architectures, platforms, and archive
mirrors.
Security fix:
* An unsafe "eval" command has been fixed. Running prokit's "install"
command with an untrusted "root" directory argument, as in the shell
command `prokit install dev/trunk "root'; echo hello #"`, allows
arbitrary code execution. This is fixed by Git commit 1ce4ec3.
This is considered a low-impact vulnerability, because running
prokit's "install" command with untrusted arguments is an unlikely
use case.
New dependencies:
* prokit now requires OpenWrt's usign utility, which verifies ed25519
signatures compatible with OpenBSD's signify utility. An embedded
copy of usign is included, which additionally requires CMake to
build, or a system copy can be used instead.
* prokit now requires gunzip, either sfdisk or fdisk, mke2fs, cpio,
and xz from XZ Utils.
Command-line interface:
* "prokit install", "prokit shell", "prokit opkg", and "prokit build"
now accept either a block device file name or a directory name
(previously only accepting the latter). A block device is
automatically mounted and unmounted on a mount point managed by
prokit.
* A new "prokit installer-pc" command has been added to install a PC
system onto a block device.
* A new "prokit mkinitramfs" command has been added to generate an
initramfs containing an installed system.
System installation changes:
* A basic "/etc/group" file is now generated on ProteanOS systems.
* "prokit install" in the ProteanOS profile now only copies
"/etc/resolv.conf" and "/etc/hostname" from the host system if the
platform is "dev". It also now does not enable system services on
the "dev" platform. On other platforms, it enables services and
sets the hostname to "proteanos".
* A list of valid ProteanOS architectures and platforms is no longer
hardcoded. This list could become outdated between prokit versions
or even ProteanOS suites.
* A list of ProteanOS package archive mirrors is no longer hardcoded.
Instead, the list is fetched from the ProteanOS files site as
needed.
* ProteanOS package feed index files are now downloaded and stored in
gzip-compressed form.
* ProteanOS package feed index file signatures are now verified
against the archive certificate, which in turn is validated against
the root archive key.
Bug fixes:
* "prokit install" now only throws a "Directory ... exists" error if
the specified root directory is not empty.
* Two bugs related to gzip-compressed package feed index files have
been fixed.
Build system and code quality:
* The build system now links all shell objects into the prokit
executable instead of distributing shell modules that are linked
into prokit at run time.
* Git commit information is now shown in "prokit version" output and
manual pages if built from a Git repository.
* Various error conditions are now handled more cleanly.
* Uses of the non-portable "%s" date format conversion specifier and
"expr" command have been replaced.
* The test suite is now based around the TAP protocol.
* Code quality has been improved: eval commands are now safer against
mistakes in input validation/escaping, echo commands have been
replaced, errors are handled (making the shell "-e" option safe), an
obselescent [ (test) command option has been removed, and commands
are protected from variable arguments beginning with "-".
ProteanOS Development Kit version 1.1.0
---------------------------------------
Released: 2014-10-08
Changes in this release:
* The previously missing prokit-install(8) manual page is now
distributed and installed.
* Some logic of "prokit install" has been simplified as ProteanOS
packages now have the necessary data files and control fields.
* "prokit build" now parses substvars files without errors.
* The current working directory is bind mounted within the isolated
file system environment and used as the working directory for the
"prokit shell" and "prokit opkg" commands.
* Compatibility with older versions of opkbuild has been dropped.
Before running "prokit build", make sure your ProteanOS system has
version 3.0.0~beta6-1 or later of the opkbuild package.
* The list of mirrors has been updated. Thanks to Morten 'Jobbe'
Jakobsen for providing another mirror.
* Session management has been added to allow multiple instances of
prokit to run simultaneously. The first instance started will mount
the basic file systems, and the last instance exited will unmount
them. A mutex is used to eliminate race conditions on changes to
the sessions pool.
* Whitespace in arguments to "prokit shell" and "prokit build" is now
preserved.
* Signals are handled during active sessions with callbacks for the
"prokit opkg" and "prokit build" commands, to ensure that the
isolated file system environment is left in a clean state when a
signal like SIGINT (Ctrl+C) is received.
ProteanOS Development Kit version 1.0.0
---------------------------------------
Released: 2014-09-02
Changes in this release:
* A new "prokit opkg" command has been added.
* A new "prokit build" command has been added.
* "prokit shell" now accepts optional command arguments.
* Manual pages for prokit commands that require superuser privileges
have been moved to section 8.
ProteanOS Development Kit version 0.1.0
---------------------------------------
Released: 2014-08-26
This is the initial release of the ProteanOS Development Kit, in
development since 2013-10-22.
This is a preview release for testing, providing only the "install" and
"shell" action commands. Currently, prokit approximately matches
miniprokit in features, though the latter is still recommended for
normal use.
