Age	Commit message (Collapse)	Author
2007-12-14	* Use strsignal if available to give better error messages for	Eelco Dolstra
	builders that fail due to a signal.
2007-11-01	* A rule to make a PDF version of the manual.	Eelco Dolstra

2007-10-29	* Depend on bash instead of sh (since we use a few bashisms).	Eelco Dolstra

2007-10-29	* On FreeBSD, sys/mount.h needs sys/param.h.	Eelco Dolstra

2007-10-27	* Detect whether chroot / bind-mount support is available.	Eelco Dolstra

2007-05-01	* Give unpacked channels more sensible names than 0, 1, ... They now	Eelco Dolstra
	get the basename of the channel URL (e.g., nixpkgs-unstable). The top-level Nix expression of the channel is now an attribute set, the attributes of which are the individual channels (e.g., {nixpkgs_unstable = ...; strategoxt_unstable = ...}). This makes attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible, e.g., "nix-env -iA nixpkgs_unstable.subversion".
2007-04-16	* It seems that svnversion prints a carriage return on Cygwin, so we	Eelco Dolstra
	get a invalid #define VERSION. Use "svnversion -n" to leave out the newline. Fix provided by Marc Weber.
2007-03-01	* Look for the openssl program at compile time. If not found, call	Eelco Dolstra
	openssl through $PATH at runtime.
2006-12-07	* Check for lchown.	Eelco Dolstra

2006-12-06	* Start of the setuid helper (the program that performs the operations	Eelco Dolstra
	that have to be done as root: running builders under different uids, changing ownership of build results, and deleting paths in the store with the wrong ownership).
2006-12-03	* Use setreuid if setresuid is not available.	Eelco Dolstra

2006-11-30	* Skeleton of the privileged worker program.	Eelco Dolstra
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
2006-11-29	* Remove --enable-setuid, --with-nix-user and --with-nix-group.	Eelco Dolstra
	Rather, setuid support is now always compiled in (at least on platforms that have the setresuid system call, e.g., Linux and FreeBSD), but it must enabled by chowning/chmodding the Nix binaries.
2006-11-13	* Don't use the result of `uname -p' on x86_64 as it gives wacky	Eelco Dolstra
	results on some machines. (NIX-69)
2006-10-19	* Require Perl 5.8.0 or newer. I mean, it is more than four years	Eelco Dolstra
	old...
2006-10-06	* Bumped the version number to 0.11.	Eelco Dolstra

2006-09-22	* Build with -D_FILE_OFFSET_BITS=64 to support files >= 2^31 bytes	Eelco Dolstra
	(NIX-22).
2006-09-20	* Check for patch (NIX-59).	Eelco Dolstra

2006-09-04	* Store the Nix libraries in ${libdir}/nix instead of ${libdir}.	Eelco Dolstra

2006-08-25	* Map "ppc" to "powerpc" so that Linux on PowerPC will be reported as	Eelco Dolstra
	"powerpc-linux".
2006-08-21	* Convert to DocBook 5.	Eelco Dolstra
	* Use Jing for RelaxNG validation, xmllint seems buggy.
2006-05-31	* On Cygwin, set the system type to i686-cygwin, and disable dynamic	Eelco Dolstra
	linking.
2006-04-25	* Unless --with-bzip2 is specified, use a copy of bzip2 in the	Eelco Dolstra
	externals directory. This is in particular useful because though most systems have bzip2/bunzip2, they don't always have libbz2, which we need for bsdiff/bspatch.
2006-03-01	* Make it easy to run individual tests from the command line.	Eelco Dolstra

2006-02-22	* Check whether "nix-store -q --graph" generates a valid dot graph.	Eelco Dolstra
	* Test "nix-store -q --tree" as well.
2006-02-13	* Optional switch "--with-openssl=<PATH>" to use OpenSSL's	Eelco Dolstra
	implementations of MD5, SHA-1 and SHA-256. The main benefit is that we get assembler-optimised implementations of MD5 and SHA-1 (though not SHA-256 (at least on x86), unfortunately). OpenSSL's SHA-1 implementation on Intel is twice as fast as ours.
2006-02-01	* bsdiff updated to 4.3. This makes Nix depend on libbz2.	Eelco Dolstra

2005-10-05	* log2xml -> nix-log2xml.	Eelco Dolstra

2005-09-21	* Use -all_load on Mac OS X.	Eelco Dolstra

2005-09-16	* Bump the version number to 0.10.	Eelco Dolstra

2005-09-15	* Check for w3m.	Eelco Dolstra

2005-09-15	* This is not a GNU project :-P	Eelco Dolstra

2005-07-22	* Build dynamic libraries.	Eelco Dolstra

2005-05-07	* Build .tar.bz2 files in `make dist'.	Eelco Dolstra

2005-04-11	* Bump the version number to 0.9.	Eelco Dolstra

2005-04-08	* Doh.	Eelco Dolstra

2005-03-21	* Fink compatibility.	Eelco Dolstra

2005-03-15	* Remove Docbook EBNF dependency.	Eelco Dolstra

2005-03-15	* Purify all corepkgs builders.	Eelco Dolstra

2005-01-12	* Bump version number to 0.8.	Eelco Dolstra

2004-12-29	* Integrated bsdiff/bspatch 4.2 (from	Eelco Dolstra
	http://www.daemonology.net/bsdiff/bsdiff-4.2.tar.gz) into the source tree. The license is a bit peculiar, but it does allow verbatim copying, which is what we do here (i.e., so don't make any changes to the sources).
2004-12-20	* Place manifests in /nix/var/nix/manifests.	Eelco Dolstra
	* Use the new patch downloader.
2004-11-14	* Bump version number to 0.7.	Eelco Dolstra

2004-10-27	* Use `atdiff' instead of `cmp' for checking test output.	Eelco Dolstra
	* Don't use local file names in tests since they will produce different parse trees depending on the current directory.
2004-10-25	* Revert r1594 - it didn't solve the problem. Instead add	Eelco Dolstra
	svn-revision to distributions, which should fix it.
2004-10-25	* Make sure that the prerelease version is included in `--version'.	Eelco Dolstra

2004-09-09	* A very dirty hack to make setuid installations a bit nicer to use.	Eelco Dolstra
	Previously there was the problem that all files read by nix-env etc. should be reachable and readable by the Nix user. So for instance building a Nix expression in your home directory meant that the home directory should have at least g+x or o+x permission so that the Nix user could reach the Nix expression. Now we just switch back to the original user just prior to reading sources and the like. The places where this happens are somewhat arbitrary, however. Any scope that has a live SwitchToOriginalUser object in it is executed as the original user. * Back out r1385. setreuid() sets the saved uid to the new real/effective uid, which prevents us from switching back to the original uid. setresuid() doesn't have this problem (although the manpage has a bug: specifying -1 for the saved uid doesn't leave it unchanged; an explicit value must be specified).
2004-09-09	* Use setre[ug]id() instead of setres[ug]id(), since the former is	Eelco Dolstra
	more common than the latter (which exists only on Linux and FreeBSD). We don't really care about dropping the saved IDs since there apparently is no way to quiry them in any case, so it can't influence the build (unlike the effective IDs which are checked by Perl for instance).
2004-08-20	* On systems that have the setresuid() and setresgid() system calls to	Eelco Dolstra
	set the real uid and gid to the effective uid and gid, the Nix binaries can be installed as owned by the Nix user and group instead of root, so no root involvement of any kind is necessary. Linux and FreeBSD have these functions.
2004-08-20	* Setuid support for sharing a Nix installation between multiple	Eelco Dolstra
	users. If the configure flag `--enable-setuid' is used, the Nix programs nix-env, nix-store, etc. are installed with the setuid bit turned on so that they are executed as the user and group specified by `--with-nix-user=USER' and `--with-nix-group=GROUP', respectively (with defaults `nix' and `nix'). The setuid programs drop all special privileges if they are executed by a user who is not a member of the Nix group. The setuid feature is a quick hack to enable sharing of a Nix installation between users who trust each other. It is not generally secure, since any user in the Nix group can modify (by building an appropriate derivation) any object in the store, and for instance inject trojans into binaries used by other users. The setuid programs are owned by root, not the Nix user. This is because on Unix normal users cannot change the real uid, only the effective uid. Many programs don't work properly when the real uid differs from the effective uid. For instance, Perl will turn on taint mode. However, the setuid programs drop all root privileges immediately, changing all uids and gids to the Nix user and group.
