Eelco Dolstra 5591fcc529 * Cache the manifests in /nix/var/nix/manifests in a SQLite database. 
This significantly speeds up the download-using-manifests
  substituter, especially if manifests are very large.  For instance,
  one "nix-build -A geeqie" operation that updated four packages using
  binary patches went from 18.5s to 1.6s.  It also significantly
  reduces memory use.

  The cache is kept in /nix/var/nix/manifests/cache.sqlite.  It's
  updated automatically when manifests are added to or removed from
  /nix/var/nix/manifests.  It might be interesting to have nix-pull
  store manifests directly in the DB, rather than storing them as
  separate flat files, but then we would need a command line interface
  to delete manifests from the DB.

Eelco Dolstra 1e7e4f21ba * Remove the localPaths feature in manifests since it's no longer used 
and redundant anyway.
 2011-04-06 09:16:22 +00:00
Eelco Dolstra 0423d0692a * Print a better error message. 2011-03-16 15:55:57 +00:00
Eelco Dolstra 48bdbbf070 * Fix a bug in the documentation (reported by Olexiy Buyanskyy, 
Nix/215).

Eelco Dolstra e945b52a31 * nix-push: handle the case where the hash is not set in the DB. 2011-02-17 13:26:33 +00:00
Eelco Dolstra c3cee5395b * Build for Ubuntu 10.04. 2011-02-14 14:56:02 +00:00
Florian Friesdorf 8fcaf3e9c6 make nix-mode provide 'nix-mode 
this enables (require 'nix-mode)
 2011-02-14 03:11:56 +00:00
Eelco Dolstra 538b7caab0 * Don't allocate a big initial GC address space on machines with 
little RAM.  Even if the memory isn't actually used, it can cause
  problems with the overcommit heuristics in the kernel.  So use a VM
  space of 25% of RAM, up to 384 MB.
 2011-02-10 14:31:04 +00:00
Eelco Dolstra 5a6b039802 * Don't call GC_expand_hp unless we're actually using the garbage 
collector.
 2011-02-09 22:59:50 +00:00
Ludovic Courtès f1462c208b Use $BDW_GC_LIBS instead of a custom variable. 2011-02-09 21:23:13 +00:00
Eelco Dolstra 1876ab764f * A better fix. $boehmgc isn't set anywhere, we should use the flags 
returned by pkg-config.
 2011-02-09 14:13:09 +00:00
Eelco Dolstra dfc4117e90 * The GC library can't be found on Solaris 
(http://hydra.nixos.org/build/890714), so don't build with GC
  support for now.
 2011-02-09 14:08:32 +00:00
Eelco Dolstra d159ea1b7e * Urgh, FreeBSD doesn't have a "seq" command. 2011-02-09 14:03:16 +00:00
Eelco Dolstra 3087b3f751 * Obsolete. 2011-02-09 12:48:54 +00:00
Eelco Dolstra eb94581d39 * Remove obsolete directory. 2011-02-09 12:43:44 +00:00
Eelco Dolstra 7bba67c401 * Remove obsolete file. 2011-02-09 12:42:15 +00:00
Eelco Dolstra d0eda1f3e9 * Merged the SQLite branch. 2011-02-09 12:41:54 +00:00
Eelco Dolstra 543988572e * Sync with the trunk. 2011-02-09 12:25:53 +00:00
Eelco Dolstra c0340eec5a 2011-02-08 12:30:28 +00:00
Eelco Dolstra 0304fda3cf * Propagate the CC setting. 2011-02-05 16:40:15 +00:00
Eelco Dolstra aeae0beba4 * Clang compatibility fix. Clang actually checks template definitions 
when they are defined
 2011-02-05 16:29:10 +00:00
Ludovic Courtès 3854fc9b42 Remove useless <config.h> inclusion from public header. 2011-01-14 13:55:58 +00:00
Eelco Dolstra 9db190eb31 * builtins.substring: if "start" is beyond the end of the string, 
return the empty string.
 2011-01-14 12:47:10 +00:00
Eelco Dolstra d6c8b995c5 * In Hydra manifests the Size field is missing, so don't rely on it. 
This caused a lot of "Use of uninitialized value" warnings from
  Perl.
 2010-12-22 10:32:32 +00:00
Eelco Dolstra c931a7aec5 * Do a short sleep after SQLITE_BUSY. 2010-12-17 17:23:15 +00:00
Eelco Dolstra b1eb252172 * Propagate the "100" exit status for failed builds through the Nix 
daemon.
 2010-12-17 11:28:26 +00:00
Eelco Dolstra eac93d6efe * Use the right `make'. 2010-12-17 09:28:51 +00:00
Eelco Dolstra a0be433fec * Disable X11 forwarding, it's not needed. 2010-12-15 14:25:54 +00:00
Eelco Dolstra f1a6b97639 * nix-copy-closure: make sure that the shell doesn't do globbing of 
`+' and `?' in filenames.  This is very slow if /nix/store is very
  large.  (This is a quick hack - a cleaner solution would be to
  bypass the shell entirely.)
 2010-12-15 08:39:37 +00:00
Eelco Dolstra 3dd02580e3 * I forgot to catch SQLiteBusy in registerValidPaths(). So 
registerValidPaths() now handles busy errors and registerValidPath()
  is simply a wrapper around it.
 2010-12-14 13:25:20 +00:00
Eelco Dolstra d787285af9 * nix-instantiate: return exit status 100 to denote a permanent build 
failure.  The build hook can use this to distinguish between
  transient and permanent failures on the remote side.
 2010-12-13 16:53:23 +00:00
Eelco Dolstra 5833243c92 * Create /nix/var/nix/db if it's missing. 2010-12-13 13:42:34 +00:00
Eelco Dolstra 100becf8d1 * createDirs(path): if path already exists, make sure it's a 
directory.
* Provide a C++ wrapper around lstat().
 2010-12-13 13:32:58 +00:00
Eelco Dolstra d7ca6f44eb * Update some comments. 2010-12-13 13:19:46 +00:00
Eelco Dolstra 542fc69062 * When doing a query (e.g. `nix-store -r --dry-run'), don't make a lot 
of expensive calls to `nix-store --check-validity'.
 2010-12-13 08:39:10 +00:00
Eelco Dolstra 4d57776813 * Use SQLite 3.7.4. 2010-12-10 11:45:56 +00:00
Eelco Dolstra e4720b1a79 * Ignore the result of sqlite3_reset(). 2010-12-08 18:19:15 +00:00
Eelco Dolstra 7d0444e244 * Bad things happen when a filehandle has the same name as a module. 2010-12-07 12:33:42 +00:00
Eelco Dolstra 8062d3af30 * `nix-store --verify --check-contents': don't hold the global GC lock 
while checking the contents, since this operation can take a very
  long time to finish.  Also, fill in missing narSize fields in the DB
  while doing this.
 2010-12-06 15:29:38 +00:00
Eelco Dolstra de79d23f76 * Retry a transaction if SQLite returns SQLITE_BUSY. This can happen 
even with a very long busy timeout, because SQLITE_BUSY is also
  returned to resolve deadlocks.  This should get rid of random
  "database is locked" errors.  This is kind of hard to test though.
* Fix a horrible bug in deleteFromStore(): deletePathWrapped() should
  be called after committing the transaction, not before, because the
  commit might not succeed.
 2010-12-05 18:23:19 +00:00
Eelco Dolstra 365f3028dd * Use CamelCase for the Perl modules. 2010-12-05 17:50:29 +00:00
Eelco Dolstra f42a505ab7 * Add a script `nix-generate-patches'. 
* Fix the binary patching test.
 2010-12-05 17:36:02 +00:00
Eelco Dolstra 77f7a6d591 * Quick hack around one of the pathological cases in bsdiff 
(namely, when there is a long region of 0s).  On one 86 MiB
  case, this cut patch generation time from 44m to 2m.
 2010-11-29 17:07:04 +00:00
Eelco Dolstra d3bba0c2d8 * Move the patch generator into a module. 2010-11-29 15:26:28 +00:00
Eelco Dolstra 9737a7eba0 * Don't generate patches if the system type differs. 2010-11-29 09:26:05 +00:00
Eelco Dolstra bd48fd97f6 * Impose a configurable time limit on patch generation. This is 
necessary because bsdiff has some pathological worst-case behaviour,
  e.g. O(n^2) on files consisting only of 0s.
 2010-11-29 09:15:45 +00:00
Eelco Dolstra 703e5a2ce2 * Sync with the trunk. 2010-11-25 14:09:13 +00:00
Eelco Dolstra 812fae424e * DrvInfo contains pointers to expressions, so DrvInfos should be 
traced by the garbage collector.  Otherwise "nix-env -u" can crash
  randomly.
 2010-11-25 13:47:34 +00:00
Eelco Dolstra d92ccbf1ac * Test whether sequences of patches work. 2010-11-17 18:01:37 +00:00
