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
Eelco Dolstra 1a211d812f * Oops. 2010-11-17 17:54:49 +00:00
Eelco Dolstra a4f0365b2d * When checking whether a patch is applicable, for efficiency, use 
`nix-store -q --hash' to get the hash of the base path rather than
  `nix-hash'.  However, only do this for estimating the size of a
  download, not for the actual substitution, because sometimes the
  contents of store paths are modified (which they shouldn't, of
  course).
 2010-11-17 17:41:59 +00:00
Eelco Dolstra 3d38a49840 * In the download size indication, take binary patches into account. 
Hopefully this doesn't slow things down too much.
 2010-11-17 17:32:25 +00:00
Eelco Dolstra f69626ed3e 2010-11-17 15:45:09 +00:00
Eelco Dolstra a07c68f05e * Finally, a test for the binary patch functionality. 2010-11-17 15:30:07 +00:00
Eelco Dolstra bf658f016f * Test that download sizes are shown correctly. 2010-11-17 14:39:02 +00:00
Eelco Dolstra 1e24cbaba3 * Fix the test. 2010-11-17 14:35:14 +00:00
Eelco Dolstra bdf089f463 * Before a build, show the disk space that the downloaded store paths 
will approximately require.
 2010-11-17 14:31:42 +00:00
Eelco Dolstra 06699d4219 * Store the NAR size in the manifest. 2010-11-17 12:57:52 +00:00
Eelco Dolstra 5693b8a7e2 * nix-push: no need to compute the NAR hash, since the Nix database 
already has it (`nix-store -q --hash').
 2010-11-17 12:51:54 +00:00
Eelco Dolstra e60c962fb8 * Add an operation `nix-store -q --size'. 2010-11-17 12:40:52 +00:00
Eelco Dolstra 1db6259076 * Implement RemoteStore::queryPathInfo(). 2010-11-17 12:08:01 +00:00
Eelco Dolstra a3883cbd28 * Store the size of a store path in the database (to be precise, the 
size of the NAR serialisation of the path, i.e., `nix-store --dump
  PATH').  This is useful for Hydra.
 2010-11-16 17:11:46 +00:00
Eelco Dolstra fb9368b5a0 * Sync with the trunk. 2010-11-16 12:49:47 +00:00
Eelco Dolstra 4aced7f8d0 * Merge the GC branch. 2010-10-29 15:04:39 +00:00
Eelco Dolstra 26def5392f * Document Boehm GC support. 2010-10-29 14:44:02 +00:00
Eelco Dolstra 3d71c8013e * Use pkgconfig to locate the Boehm GC (as suggested by Ludo), if 
--enable-gc is given.
 2010-10-29 14:00:47 +00:00
Eelco Dolstra 14fbf85380 * Set libgc's initial heap size to 384 MiB to prevent garbage 
collection in most cases (and therefore its performance overhead).
 2010-10-29 13:11:50 +00:00
Eelco Dolstra 0c4828ea05 * new(UseGC) is inexplicably slower than GC_MALLOC, so prefer the 
latter.
 2010-10-28 12:50:01 +00:00
Eelco Dolstra e11e6fb1c6 * Handle out of memory condition. 2010-10-28 12:29:40 +00:00
Eelco Dolstra 8a788e38ac * Install config.h. 2010-10-26 10:47:02 +00:00
Eelco Dolstra 11ccd44e95 * We need Bison 2.4 now. 2010-10-24 21:48:59 +00:00
Eelco Dolstra 43535499f3 * When allocating an attribute set, reserve enough space for all 
elements.  This prevents the vector from having to resize itself.
