103cfee056 * Revert r19650 (implement gc-keep-outputs by looking for derivations 
with the same name as the output) and instead use the
  DerivationOutputs table in the database, which is the correct way to
  to do things.

Eelco Dolstra
299ff64812 * Put the derivation outputs in the database. This is useful for the 
garbage collector.

1930570ad9 * Foreign key support in SQLite is not a persistent setting, so enable 
it at startup.
* Implement negative caching.  Now `make check' passes.

cfb09e0fad * Automatically abort transactions if they go out of scope without 
committing.

e0305bb7a8 * Some wrapper objects to ensure that SQLite objects are properly 
destroyed.

a053d2d8e5 * Add the deriver to the ValidPaths table. In principle we could now 
store all the derivers of a path efficiently.  But that opens a big
  can of worms with respect to garbage collector semantics.
 2010-02-18 13:48:18 +00:00
Eelco Dolstra
dbddac0fe9 * Assign an integer id to every row in the ValidPaths table in order 
to make the Refs table more space-efficient.  For instance, this
  reduces the size of the database on my laptop from 93 MiB to 18
  MiB.  (It was 72 MiB with the old schema on an ext3 disk with a 1
  KiB block size.)

eaaa13ce47 * Experimental branch for using SQLite to store the Nix database. 2010-02-18 13:14:51 +00:00
Eelco Dolstra
68e55cd9da * Since Hydra now escapes +', =' and `?' to %NN in URIs, 
nix-prefetch-url should unescape them, because `%' is not a valid
  character in store path names.

Eelco Dolstra
443673620d * Don't use ssh's -f flag since it leads to lots of lingering ssh 
processes.
 2010-02-04 02:38:40 +00:00

7ec5a65925 * Doh! The scope of $slotLock should extend to the end of the script, 
because otherwise the lock will be released at the end of the while
  loop.

c9b2d80bcd * Typo. 2010-02-04 02:05:34 +00:00
Eelco Dolstra
3cfe65e516 * Doh! Calling `system' in an END block causes the exit status in $? 
to be changed to 0.

e51a276907 * Remove the `cat' calls when not using --gzip. 2010-02-04 01:39:23 +00:00
Eelco Dolstra
408913bbaf * Revert r19796 for now. 2010-02-04 00:12:57 +00:00
Eelco Dolstra
4e17be7981 * Revert r19797, and use a simpler solution: just don't monitor build 
hooks for silence.  It's unnecessary because the remote nix-store
  command is already monitoring the real build.
 2010-02-03 21:38:41 +00:00

f859a8d3c3 * While waiting for a lock, print a sign of life every 5 minutes. 
This prevents remote builders from being killed by the
  `max-silent-time' inactivity monitor while they are waiting for a
  long garbage collection to finish.  This happens fairly often in the
  Hydra build farm.

c45de33c67 * Respect @sysconfdir@. 2010-02-03 21:13:37 +00:00
Eelco Dolstra
d0c32dc135 * In the build hook, if connecting to a machine fails, try the other 
machines of the right type (if available).  This makes the build
  farm more robust to failures.

f56a039775 * Use SSH connection sharing in the remote build script. 
* Removed the Cygwin password hack since the problem is apparently
  fixed in Visual Studio.
 2010-02-03 20:12:18 +00:00
Eelco Dolstra
bc1e478db1 * nix-copy-closure: start only one SSH connection to the server, or 
recycle an already existing connection (using  OpenSSH's connection
  sharing feature).
 2010-02-03 15:34:52 +00:00

4d8a85b8f5 * Updated the release notes. 2010-02-03 11:00:35 +00:00

3ce5f07793 * Ugly hack to make `nix-channel' work on Cygwin. 2010-02-02 17:01:16 +00:00
Eelco Dolstra
e839802720 * Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't 
support deleting the current directory.
 2010-02-02 15:29:18 +00:00
Eelco Dolstra
4bbbe25802 * Remove most Cygwin-specific code. Cygwin 1.7 implements advisory 
POSIX locks, and simulates Unix-style file deletion semantics
  sufficiently.  Note that this means that Nix won't work on Cygwin
  1.5 anymore.
 2010-02-02 15:28:36 +00:00
Eelco Dolstra
2723d9b56e * If fdatasync() isn't available, use fsync(). 2010-02-02 11:57:49 +00:00
Eelco Dolstra
07ffdc2862 * Added an option "fsync-metadata" to fsync() changes to 
/nix/var/nix/db.
* Removed the function writeStringToFile since it does (almost) the
  same thing as writeFile.
 2010-01-29 12:22:58 +00:00
Eelco Dolstra
ad529fb89f * Don't consider a store path valid if its info file exists but is 
zero bytes long.  That makes Nix more robust in case of crashes
  (especially on ext4).
 2010-01-29 11:53:58 +00:00
Eelco Dolstra
fdcaf37361 * Made `nix-store -qR --include-outputs' much faster if there are 
multiple paths specified on the command line (from O(n * m) to O(n +
  m), where n is the number of arguments and m is the size of the
  closure).
 2010-01-25 17:18:44 +00:00
Eelco Dolstra
50e34891f0 * Disable gzip compression in build-remote.pl because it puts too much 
load on the Hydra build farm (where it's unnecessary anyway because
  it has a fast connection to the build machines).  In any case,
  compression can be enabled by using the `-C' option to ssh.
 2010-01-25 16:14:45 +00:00
Eelco Dolstra
5388944e8d * Make the garbage collector do the right thing when `gc-keep-outputs' 
is enabled by not depending on the deriver.
 2010-01-25 16:04:32 +00:00
Eelco Dolstra
f0c0277970 * On startup, set the default SIGCHLD handler. This is so that Nix 
works correctly in weird environments where the SIGCHLD handler is
  set to "ignore".
 2010-01-12 12:22:38 +00:00
Eelco Dolstra
ef92a14bfe * Include config.h before the C library headers, because it defines 
_FILE_OFFSET_BITS=64.  Without it, functions like stat() fail on
  large file sizes.  This happened with a Nix store on squashfs:

  $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null
  error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type

  $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds
  File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds'
  Size: 0               Blocks: 36028797018963968 IO Block: 1024   regular empty file

  (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix
  to fail.)

945d8218fb * Build correctly against newer ATerm releases. Fixes "error: 'union' 
tag used in naming 'struct _ATerm'".
