2004-08-25 * Put the garbage collector in nix-store: operation `--gc',Eelco Dolstra6-19/+167
suboperations `--print-live', `--print-dead', and `--delete'. The roots are not determined by nix-store; they are read from standard input. This is to make it easy to customise what the roots are. The collector now no longer fails when store expressions are missing (which legally happens when using substitutes). It never tries to fetch paths through substitutes. TODO: acquire a global lock on the store while garbage collecting. * Removed `nix-store --delete'.
2004-08-24 * Validate derivation names. In particular don't allow spaces.Eelco Dolstra1-8/+19
* Drop support for the outPath attribute in derivations.
2004-08-20 * The gid should also match.Eelco Dolstra1-1/+1
2004-08-20 * Unbreak programs that are not setuid (such as nix-hash).Eelco Dolstra1-0/+3
2004-08-20 * On systems that have the setresuid() and setresgid() system calls toEelco Dolstra3-8/+32
set the real uid and gid to the effective uid and gid, the Nix binaries can be installed as owned by the Nix user and group instead of root, so no root involvement of any kind is necessary. Linux and FreeBSD have these functions.
2004-08-20 * Setuid support for sharing a Nix installation between multipleEelco Dolstra5-8/+121
users. If the configure flag `--enable-setuid' is used, the Nix programs nix-env, nix-store, etc. are installed with the setuid bit turned on so that they are executed as the user and group specified by `--with-nix-user=USER' and `--with-nix-group=GROUP', respectively (with defaults `nix' and `nix'). The setuid programs drop all special privileges if they are executed by a user who is not a member of the Nix group. The setuid feature is a quick hack to enable sharing of a Nix installation between users who trust each other. It is not generally secure, since any user in the Nix group can modify (by building an appropriate derivation) any object in the store, and for instance inject trojans into binaries used by other users. The setuid programs are owned by root, not the Nix user. This is because on Unix normal users cannot change the real uid, only the effective uid. Many programs don't work properly when the real uid differs from the effective uid. For instance, Perl will turn on taint mode. However, the setuid programs drop all root privileges immediately, changing all uids and gids to the Nix user and group.
2004-08-19 * Make sure that no build hook is set by default in the tests.Eelco Dolstra2-1/+2
* Don't use `seq' - some primitive, obsolete operating systems (Darwin) don't have it.
2004-08-18 * The default verbosity level of all Nix commands is now lvlInfo.Eelco Dolstra6-15/+13
* Builder output is written to standard error by default. * The option `-B' is gone. * The option `-Q' suppresses builder output. The result of this is that most Nix invocations shouldn't need any flags w.r.t. logging.
2004-08-18 * Flag `--no-link' suppresses symlinking to the output path.Eelco Dolstra1-11/+19
* Handle multiple derivations correctly.
2004-08-13 * WTF? More canonical system name problems ("athlon-linux" instead ofEelco Dolstra1-4/+14
"i686-linux").
2004-08-11 * The predecessor of a successor need not be present. This inEelco Dolstra1-4/+6
particular happens on distributed builds or when using push/pull.
2004-08-05 * Clean up the temporary directory for hook communication (and don'tEelco Dolstra1-0/+1
print out incorrect "build failed" messages).
2004-08-04 * Every real language has a `map' function.Eelco Dolstra2-2/+19
2004-08-04 * Allow primops with more that 1 arguments.Eelco Dolstra7-104/+102
2004-08-04 * Creating a file nix-support/no-scan in the output path of aEelco Dolstra2-3/+6
derivation disables scanning for dependencies. Use at your own risk. This is a quick hack to speed up UML image generation (image are very big, say 1 GB). It would be better if the scanner were faster, and didn't read the whole file into memory.
2004-07-30 * Doh!Eelco Dolstra1-1/+1
2004-07-30 * Use ATerm 2.2.Eelco Dolstra2-4/+4
* Include bootstrap.sh in dist.
2004-07-30 * A script to generate the Auto* stuff.Eelco Dolstra1-0/+5
2004-07-28 * Nix-build places a symlink `result' in the current directory to theEelco Dolstra1-1/+10
store object just built.
2004-07-18 * Don't pass `--with-system'.Eelco Dolstra1-1/+1
2004-07-18 * Slightly better heuristic for picking the canonical system type.Eelco Dolstra1-5/+7
Now SuSE and Red Hat should yield the same type (`i686-linux'). Mac OS X should now give `powerpc-darwin' (i.e., the version number is gone).
2004-07-09 * Hardcode the system id to be `i686-linux'.Eelco Dolstra1-1/+1
2004-07-06 * Fixed format string error.Eelco Dolstra1-1/+1
2004-07-01 * Don't go into a (sometimes infinite) loop calling the build hook.Eelco Dolstra1-16/+24
2004-07-01 * Nix-instantiate now accepts sets of derivations (just like nix-env).Eelco Dolstra1-0/+9
2004-07-01 * Nix-env operations now by default filter out any derivations forEelco Dolstra1-9/+28
system types other than the current system. I.e., `nix-env -i' won't install derivations for other system types, and `nix-env -q' won't show them. The flag `--system-filter SYSTEM' can be used to override the system type used for filtering (but not for building!). The value `*' can be used not to filter anything.
2004-07-01 * Align the columns in the output of `nix-env -q'.Eelco Dolstra1-4/+36
2004-07-01 * Allow the system attribute of derivations to be queried inEelco Dolstra1-37/+50
`nix-env -q'. * Queries can now be combined, e.g., `nix-env -q --status --system'.
2004-07-01 * Include some missing headers.Eelco Dolstra2-0/+2
2004-06-29 * Write build logs to disk again.Eelco Dolstra1-1/+29
2004-06-28 * Use ATerm 2.1.Eelco Dolstra1-3/+3
2004-06-28 * By default, `nix-env -i' now deletes previously installedEelco Dolstra2-3/+58
derivations with names matching the derivations being installed. The option `--preserve-installed / -P' overrides this behaviour.
2004-06-28 * In a realisation goal, check the result of the correspondingEelco Dolstra1-0/+6
normalisation goal.
2004-06-28 * `nix-env -u' now allows a specific version to be specified whenEelco Dolstra2-4/+10
upgrading. This fixes a bug reported by Martin: $ nix-env -i foo-1.0 $ nix-env -u foo-1.0 upgrading foo-1.0 to foo-1.1
2004-06-28 * Typo.Eelco Dolstra1-1/+1
2004-06-28 * Added a switch `--fallback'. From the manual:Eelco Dolstra17-58/+185
Whenever Nix attempts to realise a derivation for which a closure is already known, but this closure cannot be realised, fall back on normalising the derivation. The most common scenario in which this is useful is when we have registered substitutes in order to perform binary distribution from, say, a network repository. If the repository is down, the realisation of the derivation will fail. When this option is specified, Nix will build the derivation instead. Thus, binary installation falls back on a source installation. This option is not the default since it is generally not desirable for a transient failure in obtaining the substitutes to lead to a full build from source (with the related consumption of resources).
2004-06-25 * A flag `--keep-going / -k' to keep building goals if one fails, asEelco Dolstra10-144/+209
much as possible. (This is similar to GNU Make's `-k' flag.) * Refactoring to implement this: previously we just bombed out when a build failed, but now we have to clean up. In particular this means that goals must be freed quickly --- they shouldn't hang around until the worker exits. So the worker now maintains weak pointers in order not to prevent garbage collection. * Documented the `-k' and `-j' flags.
2004-06-25 * Don't throw an exception when a build fails. Just terminate theEelco Dolstra1-58/+214
goal and allow the problem to be handled elsewhere (e.g., at top-level).
2004-06-24 * Obsolete.Eelco Dolstra1-162/+0
2004-06-24 * Add a test to check that when we cannot realise a closureEelco Dolstra3-3/+26
expression, we should invalidate it and go back to the derivation for which it is a successor.
2004-06-24 * Multiple and/or failing substitutes now work.Eelco Dolstra4-19/+54
2004-06-24 * A test for multiple and/or failing substitutes.Eelco Dolstra5-5/+80
2004-06-22 * ArghhhhhhEelco Dolstra1-1/+1
2004-06-22 * Some more diagnostics changes.Eelco Dolstra2-25/+41
2004-06-22 * Nix-instantiate can return multiple store expressions.Eelco Dolstra1-1/+3
2004-06-22 * A utility script `nix-build' that builds Nix expressions and printsEelco Dolstra2-6/+30
their output paths (and only that) on standard output.
2004-06-22 * We don't really need this here.Eelco Dolstra3-165/+0
2004-06-22 * Well, it's better than printf.Eelco Dolstra1-1/+1
2004-06-22 * Started making Nix's diagnostic messages a bit more useful.Eelco Dolstra1-10/+26
2004-06-22 * Put WEXITSTATUS stuff somewhere else.Eelco Dolstra4-3/+11
