This will probably be mandatory soon, and is a step in the right
direction. Removes the deprecated meta.version, and move some meta
sections to the end of the file where I should have put them in
the first place.
This will eventually become the new stable branch (as unstable ones
are wont to do), but is worth having if you want to patch yesterday's
‘large’ files today, or need to apply patches already created with it.
“First release of the 3.1.x series. This is taken from the
"64bithash" branch.
- Adds support for -B values greater than 2GB, enabled by
-DXD3_USE_LARGESIZET=1 variable. [Enabled in nixpkgs.]
- Adds new performance and speed regression test, written in #Golang.
[Not enabled in nixpkgs.]
When compiled for large sizes, xdelta3 uses a 64bit checksum function.
This impacts both compression and speed.
Relative to 3.0.11, the new branch is currently 3-5% slower and
has 1-2% worse compression. Performance will be addressed in
future 3.1.x releases.”
Everything the builder.sh did can be done with the generic builder which
makes it easier to override attributes and also easier to read.
The reason I've done this is because of #10820, which tries to override
the preBuild hook, but the latter is hardcoded in the builder.sh of
bzip2.
I have compared the output of this against the previous version and the
only things that were different were timestamps in libbz2.a.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
Changes:
- liblz4: xxhash symbols are dynamically changed (namespace
emulation) to avoid symbol conflict
- liblz4.a (static library) no longer compiled with -fPIC by
default
Hotfix, solving issues with lz4cat.
- Fixed: incompatibility sparse mode vs console (#105)
- Fixed: LZ4IO exits too early when frame crc not present (#106)
- Fixed: incompatibility sparse mode vs append mode (#110)
- Performance fix: big compression speed boost for clang (+30%)
- New: cross-version test
Many (less easily automatically converted) old-style strings
remain.
Where there was any possible ambiguity about the exact version or
variant intended, nothing was changed. IANAL, nor a search robot.
Use `with stdenv.lib` wherever it makes sense.
