Removes tcpOnly and ephemeralKeys: reifying them as nixos
options adds little beyond improved discoverability. Until
17.09 we'll automatically translate these options into extraArgs
for convenience.
Unless reifying an option is necessary for conditional
computation or greatly simplifies configuration/reduces risk of
misconfiguration, it should go into extraArgs instead.
* Moved the wordpress sources derivation to the attribute pkgs.wordpress. This
makes it easier to override.
* Also introduce the `package` option for the wordpress virtual host config which
defaults to pkgs.wordpress.
* Also fixed the test in nixos/tests/wordpress.nix.
The Infinality bytecode interpreter is removed in favor of the new v40 TrueType
interpreter. In the past, the Infinality interpreter provided support for
ClearType-style hinting instructions while the default interpreter (then v35)
provided support only for original TrueType-style instructions. The v40
interpreter corrects this deficiency, so the Infinality interpreter is no longer
necessary.
To understand why the Infinality interpreter is no longer necessary, we should
understand how ClearType differs from TrueType and how the v40 interpreter
works. The following is a summary of information available on the FreeType
website [1] mixed with my own editorializing.
TrueType instructions use horizontal and vertical hints to improve glyph
rendering. Before TrueType, fonts were only vertically hinted; horizontal hints
improved rendering by snapping stems to pixel boundaries. Horizontal hinting is
a risk because it can significantly distort glyph shapes and kerning. Extensive
testing at different resolutions is needed to perfect the TrueType
hints. Microsoft invested significant effort to do this with its "Core fonts for
the Web" project, but few other typefaces have seen this level of attention.
With the advent of subpixel rendering, the effective horizontal resolution of
most displays increased significantly. ClearType eschews horizontal hinting in
favor of horizontal supersampling. Most fonts are designed for the Microsoft
bytecode interpreter, which implements a compatibility mode with
TrueType-style (horizontal and vertical) instructions. However, applying the
full horizontal hints to subpixel-rendered fonts leads to color fringes and
inconsistent stem widths. The Infinality interpreter implements several
techniques to mitigate these problems, going so far as to embed font- and
glyph-specific hacks in the interpreter. On the other hand, the v40 interpreter
ignores the horizontal hinting instructions so that glyphs render as they are
intended to on the Microsoft interpreter. Without the horizontal hints, the
problems of glyph and kerning distortion, color fringes, and inconsistent stem
widths--the problems the Infinality interpreter was created to solve--simply
don't occur in the first place.
There are also security concerns which motivate removing the Infinality patches.
Although there is an updated version of the Infinality interpreter for FreeType
2.7, the lack of a consistent upstream maintainer is a security concern. The
interpreter is a Turing-complete virtual machine which has had security
vulnerabilities in the past. While the default interpreter is used in billions
of devices and is maintained by an active developer, the Infinality interpreter
is neither scrutinized nor maintained. We will probably never know if there are
defects in the Infinality interpreter, and if they were discovered they would
likely never be fixed. I do not think that is an acceptable situtation for a
core library like FreeType.
Dropping the Infinality patches means that font rendering will be less
customizable. I think this is an acceptable trade-off. The Infinality
interpreter made many compromises to mitigate the problems with horizontal
hinting; the main purpose of customization is to tailor these compromises to the
user's preferences. The new interpreter does not have to make these compromises
because it renders fonts as their designers intended, so this level of
customization is not necessary.
The Infinality-associated patches are also removed from cairo. These patches
only set the default rendering options in case they aren't set though
Fontconfig. On NixOS, the rendering options are always set in Fontconfig, so
these patches never actually did anything for us!
The Fontconfig test suite is patched to account for a quirk in the way PCF fonts
are named.
The fontconfig option `hintstyle` is no longer configurable in NixOS. This
option selects the TrueType interpreter; the v40 interpreter is `hintslight` and
the older v35 interpreter is `hintmedium` or `hintfull` (which have actually
always been the same thing). The setting may still be changed through the
`localConf` option or by creating a user Fontconfig file.
Users with HiDPI displays should probably disable hinting and antialiasing: at
best they have no visible effect.
The fontconfig-ultimate settings are still available in NixOS, but they are no
longer the default. They still work, but their main purpose is to set rendering
quirks which are no longer necessary and may actually be
detrimental (e.g. setting `hintfull` for some fonts). Also, the vast array of
font substitutions provided is not an appropriate default; the default setting
should be to give the user the font they asked for.

Newer versions of DNSCrypt proxy *can* cache lookups (via
plugin); make the wording more neutral wrt. why one might want
to run the proxy in a forwarding setup.
1) The forking behavior of `buildbot start` is temporarily broken for
mysterious reasons that I'm still looking into
2) Let systemd do the forking: no point in using two different process
startup wait loops
The nixbld group belongs to nix-daemon and you really don't want to be
in it. If you are in it, nix-daemon will kill your processes when you
least expect it :)
It'd be better to do the update as an unprivileged user; for
now, we do our best to minimize the surface available. We
filter mount syscalls to prevent the process from undoing the fs
isolation.
Resolve download.dnscrypt.org using hostip with a bootstrap
resolver (hard-coded to Google Public DNS for now), to ensure
that we can get an up-to-date resolver list without working name
service lookups. This makes us more robust to the upstream
resolver list getting out of date and other DNS configuration
problems.
We use the curl --resolver switch to allow https cert validation
(we'd need to do --insecure if using just the ip addr). Note
that we don't rely on https for security but it's nice to have
it ...
Use mkMerge to make the code a little more ergonomic and easier
to follow (to my eyes, anyway ...). Also take the opportunity
to do some minor cleanups & tweaks, but no functional changes.
Set `networking.networkmanager.wifi.macAddress` or `networking.networkmanager.ethernet.macAddress`
to one of these values to change your macAddress.
* "XX:XX:XX:XX:XX:XX": set the MAC address of the interface.
* "permanent": use the permanent MAC address of the device.
* "preserve": don’t change the MAC address of the device upon activation.
* "random": generate a randomized value upon each connect.
* "stable": generate a stable, hashed MAC address.

Version 2.0.0 is installed as a separate package called "couchdb2".
When setting the config option "package" attribute to pkgs.couchdb2, a
corresponding service configuration will be generated. If a previous
1.6 installation exists, the databases can still be found on the local
port (default: 5986) and can be replicated from there.
Note that single-node or cluster setup still needs to be configured
manually, as described in
http://docs.couchdb.org/en/2.0.0/install/index.html.
The implicit behavior of pulling it out of the classpath seemed not
to work properly and could be thrown off by other things on the
classpath also providing the properties file. This guarantees that
our settings stick.
phpfpm currently uses `readFile` to read the php.ini file from the
phpPackage. This causes php to be build at evaluation time.
This eliminates the use of readFile and builds the php.ini at build
time.
This reverts commit 29caa185a7.
Not clear what the proper thing to do is. cf94cdb59b renders this
question mostly moot. Reverting before 17.03 branch to avoid a repeat
of #19054.
reason:
- We currently have an open discussion regarding a more modular
firewall (https://github.com/NixOS/nixpkgs/issues/23181) and
leaving null makes future extension easier.
- the current default might not cover all use cases (different ssh port)
and might break setups, if applied blindly
When dhcpcd instead of networkd is used, the network-online.target behaved
the same as network.target, resulting in broken services that need a working
network connectivity when being started.
This commit makes dhcpcd wait for a lease and makes it wanted by
network-online.target. In turn, network-online.target is now wanted by
multi-user.target, so it will be activated at every boot.
This is deliberate because using the taskd binary to configure
Taskserver has a good chance of messing up permissions.
The nixos-taskserver tool now can manage even manual configurations, so
there really is no need anymore to expose the taskd binary.
If people still want to use the taskd binary at their own risk they can
still add taskserver to systemPackages themselves.

Putting an include directive in the configuration file referencing a
store path with the real configuration file has the disavantage that
once we change the real configuration file the store path is also a
different one.
So we would have to replace that include directive with the new
configuration file, which is very much error-prone, because whenever
taskd modifies the configuration file on its own it generates a new one
with *only* the key/value options and without any include directives.
Another problem is that we only added the include directive on the first
initalization, so whenever there is *any* configuration change, it won't
affect anything.
We're now passing all the configuration options via command line,
because taskd treats everything in the form of --<name>=<value> to be a
configuration directive.
This also has the effect that we now no longer have extraConfig, because
configuration isn't a file anymore.
Instead we now have an attribute set that is mapped down to
configuration options.
Unfortunately this isn't so easy with the way taskd is configured,
because there is an option called "server" and also other options like
"server.cert", "server.key" and so on, which do not map very well to
attribute sets.
So we have an exception for the "server" option, which is now called
"server.listen", because it specifies the listening address.

The helper tool so far was only intended for use in automatic PKI
handling, but it also is very useful if you have an existing CA.
One of the main advantages is that you don't need to specify the data
directory anymore and the right permissions are also handled as well.
Another advantage is that we now have an uniform management tool for
both automatic and manual config, so the documentation in the NixOS
manual now applies to the manual PKI config as well.

The error message displays that a specific user doesn't exist in an
organisation, but uses the User object's name attribute to show which
user it was.
This is basically a very stupid chicken and egg problem and easily fixed
by using the user name provided on the command line.

The GeoIP databases from MaxMind have no stable URLs and change every
month (or so). Our current method of packaging these database in Nix and
playing catch-up with ever-changing file hashes is a bad idea. For
instance, it makes it impossible to realize old NixOS configurations.
This patch adds a NixOS service that periodically updates the GeoIP
databases in /var/lib/geoip-databases. Moving NixOS modules over can be
done in later patches.
I tried adding MD5 check, but not all databases have them, so i skipped
it. We are downloading over HTTPS though, it should be good. I also
tried adding zip support, but the first zip file I extracted had a
different filename inside than the archive name, which breaks an
assumption in this service, so I skipped that too.
Changes v9 -> v10:
- Pass "--max-time" to curl to set upper bound on downloads (ensures
no indefinite hanging if there's problem with networking).
Timeout for network connectivity check: 60s.
Timeout for geoip database (each): 15m.
Changes v8 -> v9:
- Mention the random timer delay in the documentation for the
'interval' option.
Changes v7 -> v8:
- Add "RemainAfterExit=true" for the setup service, so it won't be
restarted needlessly. (Thanks @danbst!)
Changes v6 -> v7:
- Add --skip-existing flag to geoip-updater, which skips updating
existing database files. Pass that flag when we run the service on
boot (and on any NixOS configuration change).
(IMHO, this is somewhat a workaround for systemd persistent timers
not being triggered immediately when a timer has never expired
before. But it does have the nice side effect of ensuring that the
installed databases always correspond to the configured ones, since
the service is now always run after configuration changes.)
Changes v5 -> v6:
- Update database files atomically (per DB)
- If a database is removed from the configuration, it'll be removed
from /var/lib/geoip-databases too (on next run).
- Add NixOS module assertion so that if user inputs non- .gz or .xz
file there will be a build time error instead of runtime.
- Run updater as user "nobody" instead of "root".
- Rename NixOS service from "geoip-databases" to "geoip-updater".
- Drop RemainAfterExit, or else the timer won't trigger the unit.
- Bring back "curl --fail", or else we won't catch and log curl
failures.
Changes v4 -> v5:
- Add "GeoLite2-City.mmdb.gz" to default database list.
Changes v3 -> v4:
- Remove unneeded geoip-updater-setup.service after adding
'wantedBy = [ "multi-user.target" ]' directly to
geoip-updater.service
- Drop unneeded "Service" name from service descriptions.
Changes v2 -> v3:
- Network may be down when starting from a cold boot, so try a few
times. Possibly, if using systemd-networkd, it'll pass on the first
try. But with default DHCP on NixOS, the service is started before
hostnames can be resolved and thus we need a few extra seconds.
- Add error handling and mark service as failed if fatal error.
- Add proper syslog log levels.
- Add RandomizedDelaySec=3600 to the timer to not put high load on the
MaxMind servers. Suggested by @Mic92.
- Set RemainAfterExit on geoip-updater.service instead of
geoip-updater-setup.service. (The latter is only a proxy that pulls
in the former service).
Changes v1 -> v2:
From Данило Глинський (Danylo Hlynskyi) <abcz2.uprola@gmail.com>:
nixos/geoip-databases: add `databases` option and fix initial setup
There were two great issues when using this service:
- When you just enable service, databases aren't downloaded, they are
downloaded when timer triggers. Fixed this with automatic download on
first system activation.
- When there is no internet, updater outputs nothing to logs, which is
IMO misbehavior. Fixed this with removing `--fail` option, better be
explicit here.
Recent versions of libreswan seem to omit this file, but it may be added/changed in the future. It is silly to have the service fail because a file is missing that only enriches the environment.
This fixes an issue where `nixops deploy` wouldn't restart the chrony
service when the chrony configuration changed, because it wouldn't
detect that `/etc/chrony.conf` was a dependency of the chrony service.
From Postfix documentation:
With this setting, the Postfix SMTP server will not reject mail with "User
unknown in local recipient table". Don't do this on systems that receive mail
directly from the Internet. With today's worms and viruses, Postfix will become
a backscatter source: it accepts mail for non-existent recipients and then
tries to return that mail as "undeliverable" to the often forged sender
address.
20e81f7c0d prevented key generation in
`preStart`, leaving the service broken for the case where the user has
no pre-existing key.
Eventually, we ought to store the state elsewhere so that `/etc` can be
read-only but for now we fix this the easy way.
Pushing to gogs only works if the `gogs` user's shell is `bash`. For error and
solution, refer to [this SO thread](http://stackoverflow.com/a/22315659)
DBus daemon now loads its config from /run/current-system/dbus.
Reloading the daemon makes it re-read that file and catch the updates
after a system upgrade.
Offline mode: When adding a lot of data, start this service.
It will will not flood the DHT since it only exposes the API.
When you are done simply reverse the process.
This allows overriding the `server_name` attribute of virtual
hosts. By doing so it is possible to have multiple virtualHost
definitions that share the same `server_name`. This is useful in
particular when you need a HTTP as well as a HTTPS virtualhost: same
server_name, different port.
