2020-12-02	Sink: Use std::string_view	Eelco Dolstra

2020-04-21	remove 'format' from Error constructor calls	Ben Burdette

2019-12-13	Improve gzip error message	Eelco Dolstra

2019-12-13	Initial gzip support	Tom Bereknyei
	Closes #3256
2018-09-17	Fix build failure if parallel xz is not available	Eelco Dolstra

2018-08-21	Fix warnings in compression.cc	Eelco Dolstra

2018-08-06	Fix Brotli decompression in 'nix log'	Eelco Dolstra
	This didn't work anymore since decompression was only done in the non-coroutine case. Decompressors are now sinks, just like compressors. Also fixed a bug in bzip2 API handling (we have to handle BZ_RUN_OK rather than BZ_OK), which we didn't notice because there was a missing 'throw': if (ret != BZ_OK) CompressionError("error while compressing bzip2 file");
2018-08-06	Require libbrotli	Eelco Dolstra

2018-05-02	Fix bzip2 compression of files > 4 GiB	Eelco Dolstra
	Bzip2's 'avail_in' parameter is declared as an unsigned int, so assigning a size_t length to it led to silent truncation. Fixes #2111.
2018-03-22	Fix build	Eelco Dolstra

2018-03-16	decompress(): Use a Source and Sink	Eelco Dolstra
	This allows decompression to happen in O(1) memory.
2018-02-11	compression: make parallel sink separate class	Will Dietz

2018-02-11	compression: print warning if parallel requested but not supported	Will Dietz

2018-02-09	configure.ac: check if lzma has MT support, fix deb build/etc.	Will Dietz

2018-02-07	make multi threaded compression configurable and use single threaded	AmineChikhaoui
	by default.
2018-02-07	set block size to 0 to let the lzma lib choose the right one, add	AmineChikhaoui
	some comments about possible improvements wrt memory usage/threading.
2018-02-06	support multi threaded xz encoder, this might be particularly useful in	AmineChikhaoui
	the case of hydra where the overhead of single threaded encoding is more noticeable e.g most of the time spent in "Sending inputs"/"Receiving outputs" is due to compression while the actual upload to the binary cache seems to be negligible.
2017-12-30	use libbrotli directly when available	Will Dietz
	* Look for both 'brotli' and 'bro' as external command, since upstream has renamed it in newer versions. If neither are found, current runtime behavior is preserved: try to find 'bro' on PATH. * Limit amount handed to BrotliEncoderCompressStream to ensure interrupts are processed in a timely manner. Testing shows negligible performance impact. (Other compression sinks don't seem to require this)
2017-07-30	Replace Unicode quotes in user-facing strings by ASCII	Jörg Thalheim
	Relevant RFC: NixOS/rfcs#4 $ ag -l \| xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-03-22	Fix xz decompression	Eelco Dolstra
	Fixes #1285.
2017-03-21	LocalFSStore::getBuildLog(): Handle corrupted logs	Eelco Dolstra

2017-03-21	Don't hang in decompression if bzip2 data ends prematurely	Eelco Dolstra

2017-03-15	runProgram(): Distinguish between empty input and no input	Eelco Dolstra
	For example, if we call brotli with an empty input, it shouldn't read from the caller's stdin.
2017-03-15	S3BinaryCacheStore: Support compression of narinfo and log files	Eelco Dolstra
	You can now set the store parameter "text-compression=br" to compress textual files in the binary cache (i.e. narinfo and logs) using Brotli. This sets the Content-Encoding header; the extension of compressed files is unchanged. You can separately specify the compression of log files using "log-compression=br". This is useful when you don't want to compress narinfo files for backward compatibility.
2017-03-15	Fix assertion failure on SIGINT	Eelco Dolstra
	nix: src/libutil/compression.cc:142: virtual nix::XzSink::~XzSink(): Assertion `finished' failed.
2017-03-15	Add support for brotli compression	Eelco Dolstra
	Build logs on cache.nixos.org are compressed using Brotli (since this allows them to be decompressed automatically by Chrome and Firefox), so it's handy if "nix log" can decompress them.
2016-11-26	Revert "Get rid of unicode quotes (#1140)"	Eelco Dolstra
	This reverts commit f78126bfd6b6c8477fcdbc09b2f98772dbe9a1e7. There really is no need for such a massive change...
2016-11-25	Get rid of unicode quotes (#1140)	Guillaume Maudoux

2016-05-04	Do compression in a sink	Eelco Dolstra

2016-05-04	Add a Store::addToStore() variant that accepts a NAR	Eelco Dolstra
	As a side effect, this ensures that signatures are propagated when copying paths between stores. Also refactored import/export to make use of this.
2016-05-04	Fix segfault in xz compression/decompression	Eelco Dolstra

2016-04-29	BinaryCacheStore: Support bzip2 compression	Eelco Dolstra

2016-04-29	BinaryCacheStore: Support "none" compression method	Eelco Dolstra

2016-04-22	Make compression interruptible	Eelco Dolstra

2016-04-15	BinaryCacheStore::readFile(): Return a shared_ptr to a string	Eelco Dolstra
	This allows readFile() to indicate that a file doesn't exist, and might eliminate some large string copying.
2016-02-15	Add xz compression function	Eelco Dolstra
	This is used by the Hydra queue runner, but since it may also be useful for the C++ rewrite of nix-push, I'm putting it here.
2016-02-15	decompressXZ: Ensure that lzma_end() is called	Eelco Dolstra
	Otherwise we might leak memory.
2016-01-05	Fixed unresolved 'BUFSIZ'	FrankHB
	`BUFSIZ` is defined in header `<cstdio>`.
2015-10-30	<nix/fetchurl.nix>: Support xz-compressed NARs	Eelco Dolstra
