2014-12-09	Explicitly include required C headers	Marko Durkovic	1	-0/+1

2014-12-05	Use posix_spawn to run the pager	Eelco Dolstra	2	-2/+9
	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...)
2014-11-25	Add a primop for regular expression pattern matching	Eelco Dolstra	2	-4/+28
	The function ‘builtins.match’ takes a POSIX extended regular expression and an arbitrary string. It returns ‘null’ if the string does not match the regular expression. Otherwise, it returns a list containing substring matches corresponding to parenthesis groups in the regex. The regex must match the entire string (i.e. there is an implied "^<pat>$" around the regex). For example: match "foo" "foobar" => null match "foo" "foo" => [] match "f(o+)(.)" "foooobar" => ["oooo" "bar"] match "(./)?([^/])" "/dir/file.nix" => ["/dir/" "file.nix"] match "(./)?([^/])" "file.nix" => [null "file.nix"] The following example finds all regular files with extension .nix or .patch underneath the current directory: let findFiles = pat: dir: concatLists (mapAttrsToList (name: type: if type == "directory" then findFiles pat (dir + "/" + name) else if type == "regular" && match pat name != null then [(dir + "/" + name)] else []) (readDir dir)); in findFiles ".\\.(nix\|patch)" (toString ./.)
2014-11-19	nix-daemon: Call exit(), not _exit()	Eelco Dolstra	2	-3/+6
	This was preventing destructors from running. In particular, it was preventing the deletion of the temproot file for each worker process. It may also have been responsible for the excessive WAL growth on Hydra (due to the SQLite database not being closed properly). Apparently broken by accident in 8e9140cfdef9dbd1eb61e4c75c91d452ab5e4a74.
2014-10-20	Fix build on gcc < 4.7	Shea Levy	1	-0/+13

2014-10-20	Revert "Drop support for pre-c++11 compilers."	Shea Levy	1	-1/+2
	The breakage this fixed can be worked around without removing support. This reverts commit 84a13dc576496f1227665259c61f86184f452f51.
2014-10-18	Drop support for pre-c++11 compilers.	Shea Levy	1	-2/+1
	In particular, gcc 4.6's std::exception::~exception has an exception specification in c++0x mode, which requires us to use that deprecated feature in nix (and led to breakage after some recent changes that were valid c++11). nix already uses several c++11 features and gcc 4.7 has been around for over 2 years.
2014-10-03	Remove some duplicate code	Eelco Dolstra	2	-0/+12

2014-10-03	nix-env: Add regular expression support in selectors	Eelco Dolstra	2	-0/+55
	So you can now do things like: $ nix-env -qa '.zip.' $ nix-env -qa '.(firefox\|chromium).'
2014-10-03	createDirs(): Handle ‘path’ being a symlink	Eelco Dolstra	1	-0/+3
	In particular, this fixes "nix-build -o /tmp/result" on Mac OS X (where /tmp is a symlink).
2014-09-19	Remove bogus comment	Eelco Dolstra	1	-1/+0

2014-08-21	Use PR_SET_PDEATHSIG to ensure child cleanup	Eelco Dolstra	2	-2/+12

2014-08-20	Use proper quotes everywhere	Eelco Dolstra	3	-42/+42

2014-08-20	Add some color	Eelco Dolstra	2	-0/+47

2014-08-20	nix-store -l: Automatically pipe output into $PAGER	Eelco Dolstra	1	-2/+2

2014-08-04	Get rid of "killing <pid>" message for unused build hooks	Eelco Dolstra	2	-3/+4

2014-08-01	Call commonChildInit() before doing chroot init	Eelco Dolstra	1	-8/+10
	This ensures that daemon clients see error messages from the chroot setup.
2014-08-01	Eliminate redundant copy	Eelco Dolstra	2	-1/+3

2014-08-01	Make readDirectory() return inode / file type	Eelco Dolstra	3	-17/+24

2014-07-31	Restore default SIGPIPE handler before invoking ‘man’	Eelco Dolstra	2	-0/+14
	Fixes NixOS/nixpkgs#3410.
2014-07-24	Use pthread_cancel instead of a signal	Eelco Dolstra	1	-5/+2
	Signal handlers are process-wide, so sending SIGINT to the monitor thread will cause the normal SIGINT handler to run. This sets the isInterrupted flag, which is not what we want. So use pthread_cancel instead.
2014-07-24	Fix bogus pass by reference	Eelco Dolstra	1	-6/+1
	http://hydra.nixos.org/build/12711659
2014-07-24	More debugging	Eelco Dolstra	1	-0/+1

2014-07-24	Add some assertions	Eelco Dolstra	1	-0/+6

2014-07-23	nix-daemon: Simplify stderr handling	Eelco Dolstra	1	-0/+1

2014-07-23	nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects	Eelco Dolstra	1	-0/+43
	The thread calls poll() to wait until a HUP (or other error event) happens on the client connection. If so, it sends SIGINT to the main thread, which is then cleaned up normally. This is much nicer than messing around with SIGPOLL.
2014-07-23	startProcess: Make writing error messages from the child more robust	Eelco Dolstra	1	-2/+4

2014-07-18	Better fix for strcasecmp on Darwin	Eelco Dolstra	1	-3/+1

2014-07-17	Ugly hack to fix building on old Darwin	Eelco Dolstra	1	-0/+3
	http://hydra.nixos.org/build/12580878
2014-07-16	Get rid of a compiler warning	Eelco Dolstra	1	-1/+2

2014-07-16	Be more strict about file names in NARs	Eelco Dolstra	1	-1/+6

2014-07-16	Handle case collisions on case-insensitive systems	Eelco Dolstra	2	-75/+100
	When running NixOps under Mac OS X, we need to be able to import store paths built on Linux into the local Nix store. However, HFS+ is usually case-insensitive, so if there are directories with file names that differ only in case, then importing will fail. The solution is to add a suffix ("~nix~case~hack~<integer>") to colliding files. For instance, if we have a directory containing xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to "xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR, the suffixes are removed. Thus, importing and exporting via a case-insensitive Nix store is round-tripping. So when NixOps calls nix-copy-closure to copy the path to a Linux machine, you get the original file names back. Closes #119.
2014-07-10	Fix broken Pid constructor	Eelco Dolstra	1	-5/+2

2014-07-10	Refactoring: Move all fork handling into a higher-order function	Eelco Dolstra	2	-54/+60
	C++11 lambdas ftw.
2014-07-10	Remove maybeVfork	Eelco Dolstra	2	-11/+1

2014-07-09	Fix compilation error on some versions of GCC	Eelco Dolstra	1	-2/+2
	src/libexpr/primops.cc:42:8: error: looser throw specifier for 'virtual nix::InvalidPathError::~InvalidPathError()' src/libexpr/nixexpr.hh:12:1: error: overriding 'virtual nix::EvalError::~EvalError() noexcept (true)' http://hydra.nixos.org/build/12385750
2014-06-12	Don't use member initialisers	Eelco Dolstra	1	-4/+4
	They're a little bit too recent (only supported since GCC 4.7). http://hydra.nixos.org/build/11851475
2014-06-12	Fix bogus warnings about dumping large paths	Eelco Dolstra	1	-2/+2
	Also, yay for C++11 non-static initialisers.
2014-06-10	Print a warning when loading a large path into memory	Eelco Dolstra	2	-4/+30
	I.e. if you have a derivation with src = ./huge-directory; you'll get a warning that this is not a good idea.
2014-05-21	nix-store -l: Fetch build logs from the Internet	Eelco Dolstra	2	-1/+3
	If a build log is not available locally, then ‘nix-store -l’ will now try to download it from the servers listed in the ‘log-servers’ option in nix.conf. For instance, if you have: log-servers = http://hydra.nixos.org/log then it will try to get logs from http://hydra.nixos.org/log/<base name of the store path>. So you can do things like: $ nix-store -l $(which xterm) and get a log even if xterm wasn't built locally.
2014-04-08	If a .drv cannot be parsed, show its path	Eelco Dolstra	2	-1/+3
	Otherwise you just get ‘expected string `Derive(['’ which isn't very helpful.
2014-04-03	Tweak error message	Eelco Dolstra	1	-1/+1

2014-03-28	Don't interpret strings as format strings	Eelco Dolstra	3	-23/+32
	Ludo reported this error: unexpected Nix daemon error: boost::too_few_args: format-string refered to more arguments than were passed coming from this line: printMsg(lvlError, run.program + ": " + string(err, 0, p)); The problem here is that the string ends up implicitly converted to a Boost format() object, so % characters are treated specially. I always assumed (wrongly) that strings are converted to a format object that outputs the string as-is. Since this assumption appears in several places that may be hard to grep for, I've added some C++ type hackery to ensures that the right thing happens. So you don't have to worry about % in statements like printMsg(lvlError, "foo: " + s); or throw Error("foo: " + s);
2014-03-12	Remove unnecessary null pointer checks	Eelco Dolstra	1	-2/+2
	Fixes #225.
2014-02-27	Set up a minimal /dev in chroots	Eelco Dolstra	3	-2/+11
	Not bind-mounting the /dev from the host also solves the problem with /dev/shm being a symlink to something not in the chroot.
2014-02-26	And another one	Eelco Dolstra	2	-41/+2

2014-02-26	Remove another unused function	Eelco Dolstra	2	-22/+0
