* lib.getExe: Do not make assumptions about the main programRobert Hensing2023-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, getExe assumes that if `meta.mainProgram` is unset, it has a main program that's named after the package name. While this is probable, it leads to a bad error when the assumption does not hold. If the user called `getExe` themselves, they might narrow down the location of the assumption quite easily, but if that's not the case, they'll have to go down the rabbit hole to figure out what went wrong. For example, a NixOS module may use `lib.getExe` on a package-typed option which is then used in the system configuration. This then typically leads to a failure *after* deployment, which is bad, and it's quite likely that the user will debug the package output contents before digging through the NixOS module, which is bad. Furthermore the `getExe` call is rather inconspicuous as it does not contain something like "/bin/foo", which is bad. Also modules can be hard to read for a newbie, which is bad. All of this can be avoided by requiring `meta.mainProgram`. Many packages already have the attribute, and I would expect 80% of `getExe` usages to be covered by 20% of packages, because plenty of packages aren't used with `getExe` anyway. Finally we could make an effort to set `mainProgram` semi-automatically using `nix-index`.

* check-meta(hasUnsupportedPlatform): use lib.meta.availableOnAdam Joseph2023-01-11
| | | | | | | | | | | | | | `hasUnsupportedPlatform` was not updated with #37395, so it does not understand attrsets in `meta.[bad]platforms`. In particular, attrsets in `meta.badPlatforms` will "fail open" and be ignored. Let's use `lib.meta.availableOn` instead of duplicating its logic. Thanks to @alyssais for [noticing][1].

* Convert libs to a fixed-pointGraham Christensen2017-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does break the API of being able to import any lib file and get its libs, however I'm not sure people did this. I made this while exploring being able to swap out docFn with a stub in #2305, to avoid functor performance problems. I don't know if that is going to move forward (or if it is a problem or not,) but after doing all this work figured I'd put it up anyway :) Two notable advantages to this approach: 1. when a lib inherits another lib's functions, it doesn't automatically get put in to the scope of lib 2. when a lib implements a new obscure functions, it doesn't automatically get put in to the scope of lib Using the test script (later in this commit) I got the following diff on the API: + diff master fixed-lib 11764a11765,11766 > .types.defaultFunctor > .types.defaultTypeMerge 11774a11777,11778 > .types.isOptionType > .types.isType 11781a11786 > .types.mkOptionType 11788a11794 > .types.setType 11795a11802 > .types.types This means that this commit _adds_ to the API, however I can't find a way to fix these last remaining discrepancies. At least none are _removed_. Test script (run with nix-repl in the PATH): #!/bin/sh set -eux repl() { suff=${1:-} echo "(import ./lib)$suff" \ | nix-repl 2>&1 } attrs_to_check() { repl "${1:-}" \ | tr ';' $'\n' \ | grep "\.\.\." \ | cut -d' ' -f2 \ | sed -e "s/^/${1:-}./" \ | sort } summ() { repl "${1:-}" \ | tr ' ' $'\n' \ | sort \ | uniq } deep_summ() { suff="${1:-}" depth="${2:-4}" depth=$((depth - 1)) summ "$suff" for attr in $(attrs_to_check "$suff" | grep -v "types.types"); do if [ $depth -eq 0 ]; then summ "$attr" | sed -e "s/^/$attr./" else deep_summ "$attr" "$depth" | sed -e "s/^/$attr./" fi done } ( cd nixpkgs #git add . #git commit -m "Auto-commit, sorry" || true git checkout fixed-lib deep_summ > ../fixed-lib git checkout master deep_summ > ../master ) if diff master fixed-lib; then echo "SHALLOW MATCH!" fi ( cd nixpkgs git checkout fixed-lib repl .types )

* treewide: Always use integers for meta.priorityAneesh Agrawal2017-05-02
| | | | | | | | | | Meta attributes types are now enforce as of commit 90b9719f4fc95e54400a66bffcc8044c568cfa4b, so ensure meta.priority is always set to an integer. This fixes evaluation of `linuxPackages_latest.virtualbox` (the impetus for this commit) and other packages that use lowPrio or hiPrio.
* Make appendToName do the right thingEelco Dolstra2014-03-10
| | | | | | | | I.e. append a suffix *before* the version, rather than after. So we get "sqlite-interactive-3.8.0.2" instead of "sqlite-3.8.0.2-interactive". The latter is broken since nix-env just sees it the suffix as part of the version, so "nix-env -u" will happily upgrade "sqlite-3.8.0.2-interactive" to "sqlite-3.9".
* openjdk: Ugly hack to fix nix-env installationEelco Dolstra2014-01-20
| | | | | | | | | | | | Nix-env always wants to install all outputs of a derivation, but this failed for openjdk/openjre because openjdk has some symlinks (such as bin/java) to openjre. Also, it prevents installing the openjre without the openjdk. So as a workaround, mess with the "outputs" attribute to fool nix-env. Also, give openjre a separate name and description. Fixes #1535.
