mkDerivation uses the dev output in buildInputs if it exits, hence the
php-with-extensions package was never built or put into the path of
packages dependent on it during build. With this fix, the php packages
built with buildEnv or withExtensions don't have any dev outputs;
packages which need the dev output can refer to the phpXXbase packages
instead.
This provides a means to build a PHP package based on a list of
extensions from another.
For example, to generate a package with all default extensions
enabled, except opcache, but with ImageMagick:
php.withExtensions (e:
(lib.filter (e: e != php.extensions.opcache) php.enabledExtensions)
++ [ e.imagick ])
So now we have only packages for human interaction in php.packages and
only extensions in php.extensions. With this php.packages.exts have
been merged into the same attribute set as all the other extensions to
make it flat and nice.
The nextcloud module have been updated to reflect this change as well
as the documentation.
Make mkExtension put headers in the dev output and use them, instead of
a different part of the current source tree, when referring to another
extension by using internalDeps.
This means external extensions can be built against the internal ones.
This means php packages can now refer to other php packages by looking
them up in the php.packages attribute and gets rid of the internal
recursive set previously defined in php-packages.nix. This also means
that in applications where previously both the php package and the
corresponding version of the phpPackages package set had to be
specified, the php package will now suffice.
This also adds the phpWithExtensions parameter to the
php-packages.nix, which can be used by extensions that need a fully
featured PHP executable.
A slight rewrite of buildEnv which:
1. Makes buildEnv recursively add itself to its output, so that it can
be accessed from any php derivation.
2. Orders the extension text strings according to their internalDeps
attribute - dependencies have to be put before dependants in the
php.ini or they will fail to load due to missing symbols.
This moves yet more extensions from the base build to
phpPackages.ext. Some of the extensions are a bit quirky and need
patching for this to work, most notably mysqlnd and opcache.
Two new parameters are introduced for mkExtension - internalDeps and
postPhpize. internalDeps is used to specify which other internal
extensions the current extension depends on, in order to provide them
at build time. postPhpize is for when patches and quirks need to be
applied after running phpize.
Patch notes:
- For opcache, older versions of PHP have a bug where header files are
included in the wrong order.
- For mysqlnd, the config.h is never included, so we include it in the
main header file, mysqlnd.h. Also, the configure script doesn't add
the necessary library link flags, so we add them to the variable
configure should have added them to.
Also, add opcache to default extensions since it significantly
increases PHP's performance and is by default enabled on Debian based
distributions. Not having it enabled by default results in a puzzling
performance loss for anyone attempting to migrate from Debian/Ubuntu
to NixOS who is unaware of this. Therefore, enable it by default. /talyz
The ./configure script prints a warning when passed this flag,
starting with 3.7:
configure: WARNING: unrecognized options: --with-threads
The reason is that there's no longer such a thing as a build
without threads.
Eliminate the warning, by only passing the flag on the older releases
that accept it.

The prefix will now be correct in case of Nix env.
Note, however, that creating a venv from a Nix env still does not function. This does not seem to be possible
with the current approach either, because venv will copy or symlink our Python wrapper. In case it symlinks
(the default) it won't see a pyvenv.cfg. If it is copied I think it should function but it does not...
This is needed in case of `python.buildEnv` to make sure site.PREFIXES
does not only point to the unwrapped executable prefix.

This PR is a story where your valiant hero sets out on a very simple adventure but ends up having to slay dragons, starts questioning his own sanity and finally manages to gain enough knowledge to slay the evil dragon and finally win the proverbial price.
It all started out on sunny spring day with trying to tackle the Nixops plugin infrastructure and make that nice enough to work with.
Our story begins in the shanty town of [NixOps-AWS](https://github.com/nixos/nixops-aws) where [mypy](http://mypy-lang.org/) type checking has not yet been seen.
As our deuteragonist (@grahamc) has made great strides in the capital city of [NixOps](https://github.com/nixos/nixops) our hero wanted to bring this out into the land and let the people rejoice in reliability and a wonderful development experience.
The plugin work itself was straight forward and our hero quickly slayed the first small dragon, at this point things felt good and our hero thought he was going to reach the town of NixOps-AWS very quickly.
But alas! Mypy did not want to go, it said:
`Cannot find implementation or library stub for module named 'nixops'`
Our hero felt a small sliver of life escape from his body. Things were not going to be so easy.
After some frustration our hero discovered there was a [rule of the land of Python](https://www.python.org/dev/peps/pep-0561/) that governed the import of types into the kingdom, more specificaly a very special document (file) called `py.typed`.
Things were looking good.
But no, what the law said did not seem to match reality. How could things be so?
After some frustrating debugging our valiant hero thought to himself "Hmm, I wonder if this is simply a Nix idiosyncrasy", and it turns out indeed it was.
Things that were working in the blessed way of the land of Python (inside a `virtualenv`) were not working the way they were from his home town of Nix (`nix-shell` + `python.withPackages`).
After even more frustrating attempts at reading the mypy documentation and trying to understand how things were supposed to work our hero started questioning his sanity.
This is where things started to get truly interesting.
Our hero started to use a number of powerful weapons, both forged in the land of Python (pdb) & by the mages of UNIX (printf-style-debugging & strace).
After first trying to slay the dragon simply by `strace` and a keen eye our hero did not spot any weak points.
Time to break out a more powerful sword (`pdb`) which also did not divulge any secrets about what was wrong.
Our hero went back to the `strace` output and after a fair bit of thought and analysis a pattern started to emerge. Mypy was looking in the wrong place (i.e. not in in the environment created by `python.withPackages` but in the interpreter store path) and our princess was in another castle!
Our hero went to the pub full of old grumpy men giving out the inner workings of the open source universe (Github) and acquired a copy of Mypy.
He littered the code with print statements & break points.
After a fierce battle full of blood, sweat & tears he ended up in 20f7f2dd71/mypy/sitepkgs.py and realised that everything came down to the Python `site` module and more specifically https://docs.python.org/3.7/library/site.html#site.getsitepackages which in turn relies on https://docs.python.org/3.7/library/site.html#site.PREFIXES .
Our hero created a copy of the environment created by `python.withPackages` and manually modified it to confirm his findings, and it turned out it was indeed the case.
Our hero had damaged the dragon and it was time for a celebration.
He went out and acquired some mead which he ingested while he typed up his story and waited for the dragon to finally die (the commit caused a mass-rebuild, I had to wait for my repro).
In the end all was good in [NixOps-AWS](https://github.com/nixos/nixops-aws)-town and type checks could run. (PR for that incoming tomorrow).
Initially discussed in #55460.
This patch adds a `buildEnv` function to `php` that has the
following features:
* `php.buildEnv { extraConfig = /* ... */; }` to specify custom
`php.ini` args for the CLI.
* `php.buildEnv { exts = phpPackages: [phpPackages.apcu] }` to
create a PHP interpreter for the CLI with the `apcu` extension.
Perl on darwin (and any other sane platform) has a pretty good threading
support, enable it.
As it turns out, we were building non-multithreaded perl on all systems,
since glibc was not part of the stdenv anymore:
nix-repl> pkgs = import <nixpkgs> {}
nix-repl> pkgs.stdenv ? glibc
false
meaning that the comments were incorrect. Thus, clear up the confusion
and remove the misleading comments, while enabling multithreading by
default. The builds will fail on unsupported platforms, and in this case
the only place is the bootstrap, where we already force
non-multithreaded perl.
As a consequence of the above, this change will cause the full rebuild
of stdenv on all platforms, including linux.
The upstream repository has been archived, with a note that this should never be needed:
https://github.com/alexcrichton/wasm-gc
It also happens to have custom patch logic that will fail the newer cargo
verification in #79975
Changes the default fetcher in the Rust Platform to be the newer
`fetchCargoTarball`, and changes every application using the current default to
instead opt out.
This commit does not change any hashes or cause any rebuilds. Once integrated,
we will start deleting the opt-outs and recomputing hashes.
See #79975 for details.
One of the motivations for this change is the following Discourse
discussion:
https://discourse.dhall-lang.org/t/offline-use-of-prelude/137
Many users have requested Dhall support for "offline" packages
that can be fetched/built/installed using ordinary package
management tools (like Nix) instead of using Dhall's HTTP import system.
I will continue to use the term "offline" to mean Dhall package
builds that do not use Dhall's language support for HTTP imports (and
instead use the package manager's support for HTTP requests, such
as `pkgs.fetchFromGitHub`)
The goal of this change is to document what is the idiomatic way to
implement "offline" Dhall builds by implementing Nixpkgs support
for such builds. That way when other package management tools ask
me how to package Dhall with their tools I can refer them to how it
is done in Nixpkgs.
This change contains a fully "offline" build for the largest Dhall
package in existence, known as "dhall-packages" (not to be confused
with `dhallPackages`, which is our Nix attribute set containing
Dhall packages).
The trick to implementing offline builds in Dhall is to take
advantage of Dhall's support for semantic integrity checks. If an
HTTP import is protected by an integrity check and a cached build
product matches the integrity check then the HTTP import is never
resolved and the expression is instead fetched from cache.
By "installing" dependencies in a pre-seeded and isolated cache
we can replace remote HTTP imports with dependencies that have
been built and supplied by Nix instead.
The offline nature of the builds are enforced by compiling the
Haskell interpreter with the `-f-with-http` flag, which disables
the interpreter's support for HTTP imports. If a user forgets
to supply a necessary dependency as a Nix build product then the
build fails informing them that HTTP imports are disabled.
By default, built packages are "binary distributions", containing
just a cache product and a Dhall expression which can be used to
resolve the corresponding cache product.
Users can also optionally enable a "source distribution" of a package
which already includes the equivalent fully-evaluated Dhall code (for
convenience), but this is disabled by default to keep `/nix/store`
utilization as compact as possible.
dependencies:
- moarvm: init at 2020.01.1
- nqp: init at 2020.01
- zef: init 0.8.2
Replaced the rakudo-star distribution with packages for raku, moarvm, nqp and
zef.
According to https://endoflife.software/programming-languages/server-side-scripting/ruby
ruby 2.4 will go end-of-life in march, where the new release of nixpkgs
will be cut. We won't be able to support it for security updates.
Remove all references to ruby_2_4 and add ruby_2_7 instead where
missing.
Mark packages that depend on ruby 2.4 as broken:
* chefdk
* sonic-pi
The rebuilds happen because changing the end-part of URL
changes the name of the resulting file as placed into nix store
(those names were wrong/confusing before this change)
The 672c3c1d2a refactor accidentally
dropped the last version component from the source URLs. This change
puts its back.

According to https://repology.org/repository/nix_unstable/problems, we have a
lot of packages that have http links that redirect to https as their homepage.
This commit updates all these packages to use the https links as their
homepage.
The following script was used to make these updates:
```
curl https://repology.org/api/v1/repository/nix_unstable/problems \
| jq '.[] | .problem' -r \
| rg 'Homepage link "(.+)" is a permanent redirect to "(.+)" and should be updated' --replace 's@$1@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
Naive concatenation of $LD_LIBRARY_PATH can result in an empty
colon-delimited segment; this tells glibc to load libraries from the
current directory, which is definitely wrong, and may be a security
vulnerability if the current directory is untrusted. (See #67234, for
example.) Fix this throughout the tree.

- Replaced python override from the final stdenv, instead we
propagate our bootstrap python to stage4 and override both
CF and xnu to use it.
- Removed CF argument from python interpreters, this is redundant
since it's not overidden anymore.
- Inherit CF from stage4, making it the same as the stdenv.
In "perl: fuse configureFlags" [1] the effects of the preConfigure
phase were merged into configureFlags. After this change values with
spaces do not reach the configure script intact.
The only flag this affects is `ldflags` for Aarch32 and Mips, and perl
builds without it on armv7l-linux so it's probably no longer required
on any platform.
Fixes:
configuring
configure flags: -de -Dcc=cc <...> -Dldflags=\"-lm -lrt\"
./Configure: eval: line 1677: unexpected EOF while looking for matching `"'
./Configure: eval: line 1678: syntax error: unexpected end of file

When `makeWrapperArgs` variable is not set, `declare -p makeWrapperArgs`
will return with 1 and print an error message to stderr.
I did not handle the non-existence case in b0633406cb
because I thought `mk-python-derivation` will always define `makeWrapperArgs`
but `wrapProgram` can be called independently. And even with `mk-python-derivation`,
`makeWrappers` will not be set unless explicitly declared in the derivation
because of https://github.com/NixOS/nix/issues/1461.
I was lead to believe that because the builds were succeeding and I confirmed
that the mechanism fails when the variable is not defined and `-o nounset` is enabled.
It appears that `wrapPython` setup hook is not running under `-o nounset`, though,
invaldating the assumption.
Now we are checking that the variable exists before checking its type, which
will get rid of the warning and also prevent future error when `-o nounset`
is enabled in the setup hook.

https://github.com/NixOS/nixpkgs/commit/a6bb2ede232940a96150da7207a3ecd15eb6328
Bash takes an assignment of a string to an array variable:
local -a user_args
user_args="(foo bar)"
to mean appending the string to the array, not parsing the string into
an array as is the case when on the same line as the declaration:
local -a user_args="(foo bar)"
b0633406cb extracted the declaration before
the newly branched code block, causing string makeWrapperArgs being added
to the array verbatim.
Since local is function scoped, it does not matter if we move it inside
each of the branches so we fix it this way.
When `makeWrapperArgs` is a Bash array, we only passed the first
item to `wrapProgram`. We need to use `"${makeWrapperArgs[@]}"`
to extract all the items. But that breaks the common string case so
we need to handle that case separately.
