2005-12-12 * Fix NIX-23: quadratic complexity in maintaining the referersEelco Dolstra4-40/+107
mapping. The referer table is replaced by a referrer table (note spelling fix) that stores each referrer separately. That is, instead of having referer[P] = {Q_1, Q_2, Q_3, ...} we store referer[(P, Q_1)] = "" referer[(P, Q_2)] = "" referer[(P, Q_3)] = "" ... To find the referrers of P, we enumerate over the keys with a value lexicographically greater than P. This requires the referrer table to be stored as a B-Tree rather than a hash table. (The tuples (P, Q) are stored as P + null-byte + Q.) Old Nix databases are upgraded automatically to the new schema.
2005-12-11 * Add a test to demonstrate the quadratic complexity of referrerEelco Dolstra2-1/+16
(de)registration, in particular garbage collection (NIX-23).
2005-12-09 * Use Berkeley DB 4.4's process registry feature to recover fromEelco Dolstra2-102/+56
crashed Nix instances, and toss out our own recovery code.
2005-12-08 * Apply the patch.Eelco Dolstra1-0/+1
2005-12-08 * A patch to make the DB_REGISTER feature work when debug info is not on.Eelco Dolstra1-0/+84
2005-12-06 * Require Berkeley DB 4.4.Eelco Dolstra2-4/+6
* Checkpoint after an upgrade.
2005-11-17 * FreeBSD compatibility fix.Eelco Dolstra1-1/+2
2005-11-17 * "Fix" the test, since we cannot feasibly support the intended semantics.Eelco Dolstra1-1/+1
2005-11-16 * Did something useful while waiting at IAD: reference scanning is nowEelco Dolstra5-31/+52
much faster.
2005-11-04 * Install signal handlers for SIGTERM and SIGHUP. This ensures thatEelco Dolstra1-0/+4
Nix is properly shut down when it receives those signals. In particular this ensures that killing the garbage collector doesn't cause a subsequent database recovery.
2005-11-04 * Memoise checkVarDefs since internally produced terms (i.e., not theEelco Dolstra1-9/+24
result of parsing) can have very heavy sharing, causing exponential complexity if we naively recurse into them. ATerms are graphs, not trees!
2005-11-04 * Scoping bug in `with'.Eelco Dolstra2-0/+14
2005-10-29 * Turn off build hooks in nix-push because of an impurity (NIX-21).Eelco Dolstra2-2/+12
2005-10-29 * Repair the referers table from the references table.Rob Vermaas1-0/+3
2005-10-20 * Prevent uids from being used for more than one buildEelco Dolstra2-37/+122
simultaneously. We do this using exclusive locks on uid files in /nix/var/nix/userpool, e.g., /nix/var/nix/userpool/123 for uid 123.
2005-10-19 * Oops. Fixed-output derivations were broken.Eelco Dolstra1-1/+0
2005-10-18 * Oops, that should be Berkeley DB 4.3. Reported by Gerco Ballintijn.Eelco Dolstra1-1/+1
2005-10-17 * Also kill all processes of the build user after the build. This isEelco Dolstra1-0/+8
critical to prevent certain kinds of 0wnage.
2005-10-17 * Before starting a build under some uid, kill all current processesEelco Dolstra1-0/+48
running under that uid.
2005-10-17 * Check that the build result is owned by the build user, and thatEelco Dolstra1-2/+13
nobody else has write permission to the build result. This catches most hack attempts.
2005-10-17 * Don't use FIFOs to make Nix create the output path on behalf of theEelco Dolstra1-68/+17
builder. Instead, require that the Nix store has sticky permission (S_ISVTX); everyone can created files in the Nix store, but they cannot delete, rename or modify files created by others.
2005-10-17 * Beginning of secure multi-user Nix stores. If Nix is started asEelco Dolstra4-58/+219
root (or setuid root), then builds will be performed under one of the users listed in the `build-users' configuration variables. This is to make it impossible to influence build results externally, allowing locally built derivations to be shared safely between users (see ASE-2005 paper). To do: only one builder should be active per build user.
2005-10-11 add @coreutils@ to correctly use coreutils to create a profile. This is neededArmijn Hemel1-1/+1
for NixOS, where we might not know our PATH in advance.
2005-10-11 * Use ATerm 2.4.2.Eelco Dolstra1-4/+4
2005-10-06 * Swap the system and version comparion columns.Eelco Dolstra1-2/+2
2005-10-06 * Document `nix-env --compare-versions'.Eelco Dolstra1-10/+69
2005-10-06 * Only colorise if we are attached to a terminal.Eelco Dolstra1-0/+3
2005-10-06 * New query option: `--compare-versions' or `-c' to compare installedEelco Dolstra2-19/+89
versions to available versions, or vice versa. For example, the following compares installed versions to available versions: $ nix-env -qc autoconf-2.59 = 2.59 automake-1.9.4 < 1.9.6 f-spot-0.0.10 - ? firefox-1.0.4 < 1.0.7 ... I.e., there are newer versions available (in the current default Nix expression) for Automake and Firefox, but not for Autoconf, and F-Spot is missing altogether. Conversely, the available versions can be compared to the installed versions: $ nix-env -qac autoconf-2.59 = 2.59 automake-1.9.6 > 1.9.4 bash-3.0 - ? firefox-1.0.7 > 1.0.4 ... Note that bash is available but no version of it is installed. If multiple versions are available for comparison, then the highest is used. E.g., if Subversion 1.2.0 is installed, and Subversion 1.1.4 and 1.2.3 are available, then `nix-env -qc' will print `< 1.2.3', not `> 1.1.4'. If higher versions are available, the version column is printed in red (using ANSI escape codes).
2005-10-05 * Update NEWS in the root directory properly.Eelco Dolstra1-1/+1
2005-10-05 * log2xml -> nix-log2xml.Eelco Dolstra8-2/+2
2005-10-05 * Install the XSL stylesheets for log to html conversion.Eelco Dolstra1-6/+14
2005-09-28 * Use "source" instead of ".".Eelco Dolstra1-4/+4
2005-09-22 * Lets not go wild with templates.Eelco Dolstra1-4/+6
2005-09-22 * Parse multi-valued options.Eelco Dolstra5-16/+54
2005-09-22 * Merge release notes.Eelco Dolstra1-0/+35
2005-09-21 * Remove other uses of IPC::Open2.Eelco Dolstra1-20/+8
2005-09-21 * Don't use IPC::Open2, it has a subtle race bug on Mac OS X 10.4. IfEelco Dolstra1-8/+2
the parent runs before the child, it closes some pipe file descriptors which causes the child to fail due to a bad file descriptor. So we just use the normal open() function instead. This fixes NIX-14 (intermittent nix-pull failures).
2005-09-21 * This doesn't parse for now.Eelco Dolstra1-1/+1
2005-09-21 * Configuration options for trusted local builds.Eelco Dolstra3-5/+43

2005-09-20 * Typo.Eelco Dolstra1-1/+1
2005-09-18 * Use a statically linked ATerm library and build it at -O1, sinceEelco Dolstra1-1/+2
higher optimisation levels cause statically linked libraries to barf.
