2016-09-21 printMsg(lvlError, ...) -> printError(...) etc.Eelco Dolstra1-5/+5
2016-09-21 Some notational convenience for formatting stringsEelco Dolstra1-10/+3
We can now write throw Error("file '%s' not found", path); instead of throw Error(format("file '%s' not found") % path); and similarly printError("file '%s' not found", path); instead of printMsg(lvlError, format("file '%s' not found") % path);

2016-09-20 nix-shell: Fix $PATH handling in the impure caseEelco Dolstra1-0/+15
We were passing "p=$PATH" rather than "p=$PATH;", resulting in some invalid shell code. Also, construct a separate environment for the child rather than overwriting the parent's.
2016-09-16 Make computeFSClosure() single-threaded againEelco Dolstra1-0/+11
The fact that queryPathInfo() is synchronous meant that we needed a thread for every concurrent binary cache lookup, even though they end up being handled by the same download thread. Requiring hundreds of threads is not a good idea. So now there is an asynchronous version of queryPathInfo() that takes a callback function to process the result. Similarly, enqueueDownload() now takes a callback rather than returning a future. Thus, a command like nix path-info --store https://cache.nixos.org/ -r /nix/store/slljrzwmpygy1daay14kjszsr9xix063-nixos-16.09beta231.dccf8c5 that returns 4941 paths now takes 1.87s using only 2 threads (the main thread and the downloader thread). (This is with a prewarmed CloudFront.)
2016-09-16 printMsg(): Don't check for interruptsEelco Dolstra1-8/+8
Having the logger function potentially throw exceptions is Heisenbuggy.

2016-06-02 createTempDir(): Don't do a chown on LinuxEelco Dolstra1-0/+2
It's not needed and can cause problems in a user namespace.
2016-04-29 Support Git repos in the Nix pathEelco Dolstra1-0/+6
E.g. $ nix-build -I nixpkgs=git://github.com/NixOS/nixpkgs '<nixpkgs>' -A hello This is not extremely useful yet because you can't specify a branch/revision.
2016-04-25 Improved logging abstractionEelco Dolstra1-110/+3
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
2016-04-20 Cache path info lookups in SQLiteEelco Dolstra1-0/+12
This re-implements the binary cache database in C++, allowing it to be used by other Store backends, in particular the S3 backend.
2016-03-29 Improve SIGINT handling in multi-threaded programsEelco Dolstra1-2/+4
The flag remembering whether an Interrupted exception was thrown is now thread-local. Thus, all threads will (eventually) throw Interrupted. Previously, one thread would throw Interrupted, and then the other threads wouldn't see that they were supposed to quit.
2016-03-29 Add "nix verify-paths" commandEelco Dolstra1-1/+1
Unlike "nix-store --verify-path", this command verifies signatures in addition to store path contents, is multi-threaded (especially useful when verifying binary caches), and has a progress indicator. Example use: $ nix verify-paths --store https://cache.nixos.org -r $(type -p thunderbird) ... [17/132 checked] checking ‘/nix/store/rawakphadqrqxr6zri2rmnxh03gqkrl3-autogen-5.18.6’
2016-02-28 Fix reading symlinksEelco Dolstra1-1/+1
The st_size field of a symlink doesn't have to be correct, e.g. for /dev/fd symlinks.
2016-02-24 deletePath(): Succeed if path doesn't existEelco Dolstra1-4/+8
Also makes it robust against concurrent deletions.

2016-01-05 Merge pull request #685 from vizanto/masterEelco Dolstra1-1/+1
POSIX compliant directory access (fixes build on Solaris)
2015-11-25 Use DT_UNKNOWN when dirent d_type extension is not supported.Danny Wilson1-5/+1
edolstra: “…since callers of readDirectory have to handle the possibility of DT_UNKNOWN anyway, and we don't want to do a stat call for every directory entry unless it's really needed.”

2015-11-07 Fix build on SolarisDanny Wilson1-0/+4
d_type is not part of the POSIX spec unfortunately.

2015-08-07 baseNameOf: Enhance `basename` compatibilityKirill Elagin1-3/+12
* If the path ends with a slash, drop it. * If the remaining path doesn’t contain slashes, just return it. Fixes #574.
2015-07-20 Support systemd log severity prefixesEelco Dolstra1-0/+12
This is mostly useful for hydra-queue-runner.
2015-07-17 OCD: foreach -> C++11 ranged forEelco Dolstra1-4/+4
2015-06-17 Support URLs in $NIX_PATHEelco Dolstra1-0/+14
This didn't work (despite claims in the manual), because the colon in "http://" was parsed as a element separator. So handle "://" specially.
2015-06-09 Use std::vector::data()Eelco Dolstra1-6/+5
2015-05-13 cygwin: looks like stdout/stdin are reserved wordsRok Garbas1-10/+10
2015-04-09 Implement caching of fetchurl/fetchTarball resultsEelco Dolstra1-0/+20
ETags are used to prevent redownloading unchanged files.
2015-02-10 Add base64 encoder/decoderEelco Dolstra1-0/+59
2015-02-04 Use libsodium instead of OpenSSL for binary cache signingEelco Dolstra1-6/+19
Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA signatures. Public keys are also much shorter, so they're now specified directly in the nix.conf option ‘binary-cache-public-keys’. The new command ‘nix-store --generate-binary-cache-key’ generates and prints a public and secret key.
2015-01-02 libutil: Limit readLink() error to only overflows.aszlig1-2/+2
Let's not just improve the error message itself, but also the behaviour to actually work around the ntfs-3g symlink bug. If the readlink() call returns a smaller size than the stat() call, this really isn't a problem even if the symlink target really has changed between the calls. So if stat() reports the size for the absolute path, it's most likely that the relative path is smaller and thus it should also work for file system bugs as mentioned in 93002d69fc58c2b71e2dfad202139230c630c53a.

2015-01-02 libutil: Improve errmsg on readLink size mismatch.aszlig1-1/+5
A message like "error: reading symbolic link `...' : Success" really is quite confusing, so let's not indicate "success" but rather point out the real issue. We could also limit the check of this to just check for non-negative values, but this would introduce a race condition between stat() and readlink() if the link target changes between those two calls, thus leading to a buffer overflow vulnerability. Reported by @Ericson2314 on IRC. Happened due to a possible ntfs-3g bug where a relative symlink returned the absolute path (st_)size in stat() while readlink() returned the relative size.

2014-12-10 Revert "Use posix_spawn to run the pager"Eelco Dolstra1-8/+2
This reverts commit d34d2b2bbf784c0bb420a50905af25e02c6e4989.
2014-12-05 Use posix_spawn to run the pagerEelco Dolstra1-2/+8
In low memory environments, "nix-env -qa" failed because the fork to run the pager hit the kernel's overcommit limits. Using posix_spawn gets around this. (Actually, you have to use posix_spawn with the undocumented POSIX_SPAWN_USEVFORK flag, otherwise it just uses fork/exec...)
2014-11-19 nix-daemon: Call exit(), not _exit()Eelco Dolstra1-2/+5
This was preventing destructors from running. In particular, it was preventing the deletion of the temproot file for each worker process. It may also have been responsible for the excessive WAL growth on Hydra (due to the SQLite database not being closed properly). Apparently broken by accident in 8e9140cfdef9dbd1eb61e4c75c91d452ab5e4a74.
2014-10-03 Remove some duplicate codeEelco Dolstra1-0/+10
2014-10-03 createDirs(): Handle ‘path’ being a symlinkEelco Dolstra1-0/+3
In particular, this fixes "nix-build -o /tmp/result" on Mac OS X (where /tmp is a symlink).
