Previously, when downloading src failed for other reason than hash mismatch,
the error ended up in newHash. This made evaluation fail since the error message
is not valid hash. Now the failure will make newHash empty.
It is also much cleaner than previously since \K is very cool thing
and we no longer grep for legacy messages.
Fix issues reported by shellcheck and few other style issues.
Though we need to ignore $systemArg complaints because Nix does not support passing --system as a single argument.
Some fetcher functions support SRI-style `hash` attribute in addition to legacy type-specific attributes. When `hash` is used `outputHashAlgo` is null so let’s complain when SRI-style hash value was not detected.
Such attributes match the form ${type}${separator}${hash}: True SRI uses dash as a separator and only supports base64, whereas Nix’s SRI-style format uses a colon and supports all the same encodings like regular hashes (16/32/64).
To keep this program reasonably simple, we will upgrade Nix’s SRI-like format to pure SRI instead of preserving it.
--ignore-same-hash allows ignoring if the same has is used.
This gives the ability to run update-source-version multiple times to
change multiple keys.
Fix version-key, which was not being used to determine the oldVersion
variable.
If $attr.src.drvAttrs.urls is not found, look for
$attr.src.drvAttrs.url since it is being used like that in fetchgit
You can now optionally invoke update-source-versions with:
* --system flag changing the host platform, to be passed dirrectly to Nix commands.
This is useful for binary packages which have different sources for each platform.
* --file flag allowing to change the file to be modified. This is useful for packages
that offer multiple variants, listed in a different file than the derivation itself;
e.g. packages.nix of Sublime Text 3.
* --version-key, which is now a keyword flag instead of a positional argument.
Adds a script to help automatically upgrading packages: this one can
patch name/version attributes like:
version = "50.1.0";
name = "bc-1.06";
... to the given version, and updates the sha256 hash to match.
Usage is:
update-source-version <attr> <new-version> [<new-source-hash>]
where:
- attr is the attribute path of the package
- new-version is the version string to be patched in
- new-source-hash is the optional sha256/etc. hash of the source.
If not given, the script will automatically calculate it.
This is added to a subdirectory where other useful scripts can be added
in the future, like figuring out the newest version from a git repo or
GitHub releases etc.
