Replace POSIX `[ ]` with bash `[[ ]]` on six conditionals: file existence
checks, string comparisons, and -n tests. Also normalise `=` to `==` in
the string comparison.

* add hook to allow customizing before kernel make env creation
* Hook runs in docker_cli_prepare_launch() just before DOCKER_EXTRA_ARGS
is processed, allowing extensions to add Docker arguments with a more
descriptive hook name than add_host_dependencies.
* Extension: ccache-remote
Enables ccache with remote Redis storage for sharing compilation cache across build hosts.
Features:
- Auto-discovery via Avahi/mDNS (ccache.local hostname)
- Explicit Redis server configuration via CCACHE_REMOTE_STORAGE
- Build statistics display at end of build (hit/miss/error rates)
- Support for both Docker and native builds
- Hooks for kernel and u-boot compilation environments
Documentation includes server setup instructions with security warnings,
client mDNS configuration, and cache sharing requirements.
* uboot: fix ccache environment and add extension hook
U-Boot build uses `env -i` which clears all environment variables.
CCACHE_DIR and CCACHE_TEMPDIR were not explicitly passed to make,
unlike kernel build (kernel-make.sh). This caused ccache to use
default directory instead of configured Armbian one, breaking
cache statistics and shared cache functionality.
Changes:
- Add CCACHE_DIR and CCACHE_TEMPDIR to uboot_make_envs
- Add uboot_make_config hook for extensions (similar to kernel_make_config),
allowing modification of environment variables before compilation
* add long list of allowed ccache-related env vars
* set permissions to ccache files RW for everyone if cache not private
* ccache: add ccache_post_compilation hook for extensions
* ccache-remote: use ccache_post_compilation hook instead of cleanup handler
Show remote ccache stats after each compilation (kernel, uboot) via hook,
instead of once at the end via cleanup handler. Stats now shown even on
build failure.
* ccache: show stats with safe arithmetic
* ccache/uboot: improve code comments per review feedback
- uboot.sh: clarify ARMBIAN=foe workaround for dual-compiler scenario
- ccache-remote.sh: document that CCACHE_REDIS_CONNECT_TIMEOUT must be
set before extension loads
* ccache-remote: mask storage URLs in logs
Mask CCACHE_REMOTE_STORAGE when emitting Docker env debug logs.
* ccache-remote: extract ccache_inject_envs() helper to deduplicate passthrough loops
Extract ccache_inject_envs() helper to deduplicate identical passthrough
loops in kernel and uboot make config hooks.
ccache-remote: rename functions to follow project naming conventions
Rename get_redis_stats and mask_storage_url to ccache_get_redis_stats
and ccache_mask_storage_url to follow project naming conventions.
ccache-remote: mask credentials in debug log output for passthrough loops
Mask CCACHE_REMOTE_STORAGE value through ccache_mask_storage_url() before
logging in both Docker env and make env passthrough loops to avoid leaking
credentials into build logs.
* ccache-remote: add HTTP/WebDAV backend and DNS discovery
* ccache-remote: move extension script into directory layout
* ccache-remote: add server setup docs and config files
* ccache-remote: validate Redis credentials in URLs
* ccache-remote: document Redis auth options and safe passwords
Add separate insecure config example for trusted networks.
Recommend URL-safe hex passwords and update setup docs.
* ccache-remote: improve Docker loopback handling and IPv6 host parsing
- we've had SKIP_EXTERNAL_TOOLCHAINS=yes for ~5 years now
- drop all usages, mostly through `find_toolchains()`
- drop all manual PATH env injections (we've centralized if ever needed)
Update all copyright notices in shell scripts from 2025 to 2026.
## Changes
- **Igor Pecovnik**: 2013-2025 → 2013-2026 (129 files)
- **Ricardo Pardini**: 2023-2025 → 2023-2026, 2020-2025 → 2020-2026 (5 files)
## Additional Improvements
Also updated the backtitle in `lib/functions/configuration/interactive.sh`:
- Changed title from "Armbian building script" to "Armbian Linux build framework"
- Removed docs link for cleaner display
- Uses dynamic year calculation with separate declaration (fixes shellcheck SC2155)
* Add option for number of threads used by build system
Attempt to fix https://github.com/armbian/build/issues/6907
* Add CPUTHREADS to replace USEALLTHREADS
Defaults to 150% as was always the case, otherwise allow user to override number of threads.
- we might want to have different welcome colors for stable and nightly images
- this adds another branding option alongside with VENDOR, VENDORURL, VENDORSUPPORT, ...
* Refactor armbian-config into install as external package
- https://github.armbian.com/configng repository is always present
- package can still be removed from the install list
Since this tool will have deeper integration with Armbian, we should probably drop possibility to remove the tool from the list.
* Enable armbian-config as extension
- https://tracker.debian.org/news/1579223/software-properties-removed-from-testing/
- that provides add-apt-repository, but we don't use that on Debian, hopefully
- move also cpufrequtils hack (which requires release) to specific function after userspace checks and when DISTRIBUTION is set
- `software-properties-gtk` if of course also gone, so remove that for desktop's sake
- Fixes: 71296430fa -- which only set `SKIP_ARMBIAN_REPO=yes` when `rootfs` cli shortcut used
- GHA artifact pipelines are generic across all artifacts, and don't use the cli shortcuts
- instead, they use the `artifact` shortcut, with the `WHAT=rootfs` parameter
- so in GHA pipelines `SKIP_ARMBIAN_REPO=yes` was not taking effect
- rootfs artifact itself now enforces `SKIP_ARMBIAN_REPO` to be `yes` and makes it readonly
- also add `SKIP_ARMBIAN_REPO` to the general change-tracking for more clarity about configs and hooks etc
- add change tracking calls before/after generic artifact config adapter for even more clarity
- `NETWORKING_STACK` can be set to `none` (in config phase, pre-extensions) to not-add any networking extensions
- keep defaulting to systemd-networkd if BUILD_MINIMAL and NetworkManager otherwise
- fix typo in extension name
- add `NETWORKING_STACK` to change-tracking
- Rename extensions with "net-*" prefix
- Put the extensions into their own folder
- Split off time sync packages into their own extensions to be able to be used separately
- Put their config files into directories instead of using inline `cat <<- EOF >`
- Move some other NetworkManager related stuff into the extension
- Remove unneeded steps
- Install iproute2 by default on all images (for the `ip` command)
- use Chrony with Network Manager
- use timesync with systemd-networkd
- use NetPlan with Network manager only
- move command-not-found to CLI image only
- improve firstlogin ip detection
- in preparation for tightening the shellcheck severity level
- it needs to be able to follow all sources; dynamic ones are ignored, static ones need root-relative prefix
