Eelco Dolstra b3e8d72770 Merge pull request #762 from ctheune/ctheune-floats 
Implement floats
 2016-02-12 12:49:59 +01:00
Eelco Dolstra fa7cd5369b StoreAPI -> Store 
Calling a class an API is a bit redundant...
 2016-02-04 14:48:42 +01:00
Eelco Dolstra c10c61449f Eliminate the "store" global variable 
Also, move a few free-standing functions into StoreAPI and Derivation.

Also, introduce a non-nullable smart pointer, ref<T>, which is just a
wrapper around std::shared_ptr ensuring that the pointer is never
null. (For reference-counted values, this is better than passing a
"T&", because the latter doesn't maintain the refcount. Usually, the
caller will have a shared_ptr keeping the value alive, but that's not
always the case, e.g., when passing a reference to a std::thread via
std::bind.)

Eelco Dolstra d34d2b2bbf Use posix_spawn to run the pager 
In low memory environments, "nix-env -qa" failed because the fork to
run the pager hit the kernel's overcommit limits. Using posix_spawn
gets around this. (Actually, you have to use posix_spawn with the
undocumented POSIX_SPAWN_USEVFORK flag, otherwise it just uses
fork/exec...)

Shea Levy 64e23d0a38 Add download-via-ssh substituter 
This substituter connects to a remote host, runs nix-store --serve
there, and then forwards substituter commands on to the remote host and
sends their results to the calling program. The ssh-substituter-hosts
option can be specified as a list of hosts to try.

This is an initial implementation and, while it works, it has some
limitations:

* Only the first host is used
* There is no caching of query results (all queries are sent to the
  remote machine)
* There is no informative output (such as progress bars)
* Some failure modes may cause unhelpful error messages
* There is no concept of trusted-ssh-substituter-hosts

Eelco Dolstra 2bd0fcc966 Use libnix as a prefix for all Nix libraries 
In particular "libutil" was always a problem because it collides with
Glibc's libutil.  Even if we install into $(libdir)/nix, the linker
sometimes got confused (e.g. if a program links against libstore but
not libutil, then ld would report undefined symbols in libstore
because it was looking at Glibc's libutil).

Eelco Dolstra c1f3a1a89b Disallow undefined symbols in dynamic libraries by default 
This encourages that each library declares its own dependencies
properly.
 2013-11-24 00:10:00 +01:00
Eelco Dolstra 5a1114ecdb Drop the dependency on libgc in libmain 
Instead, libexpr now depends on libgc.  This means commands like
nix-store that don't do any evaluation no longer require libgc.
