build: derive PKG_SOURCE_DATE_EPOCH from the unpacked source tree

2026-06-02T09:51:00Z

Previously PKG_SOURCE_DATE_EPOCH came from a git log on the OpenWrt package directory. That fails in shallow feed clones and in the SDK (no .git), collapsing to the script's mtime and breaking .apk reproducibility across SDK rebuilds and between buildbot and SDK. With this comment, PKG_UNPACK generates a version.date file, later used to determine a reproducible SOURCE_DATE_EPOCH. Since unpack happens after download, the evaluation of SOURCE_DATE_EPOCH is now lazy, invoking the `get_source_date_epoch.sh` script on every use. While at it, drop export of PKG_SOURCE_DATE_EPOCH and clean it from the ipkg-build script.

scripts: fix installed-size calculation

2024-01-08T13:08:06Z

Previously the script would calculate the size of the compressed archive which isn't the size installed in the overlayfs. This commit uses zcat in combination with wc to calculate the umcompressed size. Signed-off-by: Paul Spooren

build: use numeric-owner in ipkg-build

2022-04-19T20:59:50Z

To create packages the `ipkg-build` script is used which double packs `control.tar.gz` and `data.tar.gz` to a single package. By default it's using a verbose username instead of a numeric value for files. Official OpenWrt images (artifacts) are created within docker containers which do not seem to contain those verbose usernames and instead defaults to numeric values. This becomes a problem when rebuilding public artifacts because other build environments may offer verbose usernames and there the created packages is different from the official ones. With this commit `ipkg-build` always uses numeric values for user/group and thereby making it easier to reproduce official artifacts. Signed-off-by: Paul Spooren

scripts: make sure sort-order is independent from locale

2022-04-06T16:33:31Z

Set LC_ALL=C environment variable when calling 'sort' as the sort order otherwise depends on the locale set. Fixes: 56ce110b73 ("scripts: make sure conffiles are sorted") Signed-off-by: Daniel Golle

scripts: make sure conffiles are sorted

2022-04-01T12:08:58Z

It may happen that conffiles are in different order on different builds. Make sure they have the same order by sorting them. FIX: #9612 Signed-off-by: Paul Spooren

scripts,ipkg-build: use realpath for pkg_dir

2021-03-15T05:32:30Z

This allows manual execution of the ipkg-build script even with releative path. Signed-off-by: Paul Spooren

scripts,ipkg-build: apply shellcheck

2021-03-15T05:31:43Z

This commit cleans the `ipkg-build` script via changes suggested by shellcheck. These are mostly word splitting issues. Remove the definition of GZIP, this adds three "lookups" of the `gzip` binary but the rest of the build system doesn't seem to use such improvements neither. Signed-off-by: Paul Spooren

scripts: ipkg-build: simplify uid/gid resolving

2020-09-14T15:11:04Z

Use the prepared .packageusergroup file to lookup user and group names when processing the passed file mode. Also replace the various subshell/cut invocations with a sequence of standard variable interpolations which fixes paths with embedded colons as a side-effect. Signed-off-by: Jo-Philipp Wich

build: add user/group ID resolve function

2020-09-14T09:54:52Z

With the introduction of `./tmp/userids` the `ipkg-build` script can now resolve values of "PKG_FILE_MODES", allowing users to set names rather than numeric values. Signed-off-by: Paul Spooren
