Sergei Trofimovich fe068eca00 mk: add support for passing LDFLAGS to libs and bins
autotools-based systems usually allow user to
append own LDFLAGS like
    LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu"
at ./configure stage

This change plumbs LDFLAGS through similar to existing CXXFLAGS variable.

Niklas Hambüchen 57daa860e8 autoconf: Fix C++17 detection not working on Ubuntu 16.04.
And probably many other distributions.

Until now, ./configure would fail silently printing a warning

    ./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found

and then continuing, later failing with a C++ #error saying that some C++11
feature isn't supported (it didn't even get to the C++17 features).

This is because older distributions don't come with the
`AX_CXX_COMPILE_STDCXX_17` m4 macro.

This commit vendors that macro accordingly.

Now ./configure complains correctly:

    configure: error: *** A compiler with support for C++17 language features is required.

On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with
gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
using:

    ./bootstrap.sh
    ./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)

Niklas Hambüchen 1f97b16b1d autoconf: Work around editline not being found on Ubuntu 16.04.
And probably other Linux distributions with long-term support releases.

Also update manual stating what version is needed;
I checked that 1.14 is the oldest version with which current nix compiles,
and added autoconf feature checks for some functions added in that release
that nix uses.

Niklas Hambüchen 00a450026f autoconf: Detect boost, require version, set CXXFLAGS.
This turns previous compiler errors complaining about missing files
into proper ./configure time errors telling the user which version
of boost is required.

Niklas Hambüchen 96cd3d6073 autoconf: Change quotes in description.
The unbalanced single-quotes cause many editor syntax highlighters
to interpret the rest of the file as a string literal, making it easier
to make syntax mistakes in absence of proper highlighting.

Merge pull request #2977 from aniketd/2971-cannot-disable-http2
Fix `http2 = false` having no effect.
2019-06-28 19:58:42 +02:00
Aniket Deshpande ec58ba38c5
Fix http2 = false having no effect. Fixes #2971.
Setting `http2 = false` in nix config (e.g. /etc/nix/nix.conf)
had no effect, and `nix-env -vvvvv -i hello` still downloaded .nar
packages using HTTP/2.

In `src/libstore/download.cc`, the `CURL_HTTP_VERSION_2TLS` option was
being explicitly set when `downloadSettings.enableHttp2` was `true`,
but, `CURL_HTTP_VERSION_1_1` option was not being explicitly set when
`downloadSettings.enableHttp2` was `false`.

This may be because `https://curl.haxx.se/libcurl/c/libcurl-env.html` states:
"You have to set this option if you want to use libcurl's HTTP/2 support."
but, also, in the changelog, states:
"DEFAULT
Since curl 7.62.0: CURL_HTTP_VERSION_2TLS
Before that: CURL_HTTP_VERSION_1_1"

So, the default setting for `libcurl` is HTTP/2 for version >= 7.62.0.

In this commit, option `CURLOPT_HTTP_VERSION` is explicitly set to
`CURL_HTTP_VERSION_1_1` when `downloadSettings.enableHttp2` nix config
setting is `false`.

This can be tested by running `nix-env -vvvvv -i hello | grep HTTP`

Matthew Bauer ec0087df0a Don’t use entire /etc/nsswitch.conf file
The default nsswitch.conf(5) file in most distros can handle many
different things including host name, user names, groups, etc. In Nix,
we want to limit the amount of impurities that come from these things.
As a result, we should only allow nss to be used for gethostbyname(3)
and getservent(3).

Fix 32-bit overflow with --no-net
--no-net causes tarballTtl to be set to the largest 32-bit integer,
which causes comparison like 'time + tarballTtl < other_time' to
fail on 32-bit systems. So cast them to 64-bit first.

Add '--no-net' convenience flag
This flag

* Disables substituters.

* Sets the tarball-ttl to infinity (ensuring e.g. that the flake
  registry and any downloaded flakes are considered current).

* Disables retrying downloads and sets the connection timeout to the
  minimum. (So it doesn't completely disable downloads at the moment.)

Fix 'error 9 while decompressing xz file'
Once we've started writing data to a Sink, we can't restart a download
request, because then we end up writing duplicate data to the
Sink. Therefore we shouldn't handle retries in Downloader but at a
higher level (in particular, in copyStorePath()).

Fixes #2952.

Eelco Dolstra e84c265645 Run builds in a pseudo-terminal
This allows many programs (e.g. gcc, clang, cmake) to print colorized
log output (assuming $TERM is set to a value like "xterm").

There are other ways to get colors, in particular setting
CLICOLOR_FORCE, but they're less widely supported and can break
programs that parse tool output.

Daemon: warn when an untrusted user cannot override a setting
In a daemon-based Nix setup, some options cannot be overridden by a
client unless the client's user is considered trusted.

Currently, if an untrusted user tries to override one of those
options, we are silently ignoring it.

This can be pretty confusing in certain situations.

e.g. a user thinks he disabled the sandbox when in reality he did not.

We are now sending a warning message letting know the user some options
have been ignored.

Related to #1761.
