Ensures that Aarch32 Arm builds with an Armv8 compiler do not set
BROTLI_64_BITS.
This scenario is possible with ChromeOS builds, as they may use a
toolchain with the target armv7-cros-gnueabi, but with -march=armv8.
This will set __ARM_ARCH to 8 (defining BROTLI_TARGET_ARMV8), but will
also set __ARM_32BIT_STATE and not __ARM_64BIT_STATE. Without this,
illegal 64-bit non-word-aligned reads (LDRD) may be emitted.
Also fix unaligned 64-bit reads on AArch32 - STRD was still possible to
emit.

Our dist tarball is missing hash_rolling_inc.h and
hash_composite_inc.h, which causes subsequent autotools
builds to fail. Fix this by adding it to the sources list.

* Update go_library to use standard importpath
Instead of using go_prefix, which is deprecated, the importpath attribute is made explicit.
* Add description to go/BUILD
* Inverse bazel workspace tree.
Now each subproject directly depends on root (c) project.
This helps to mitigate Bazel bug bazelbuild/bazel#2391; short summary:
Bazel does not work if referenced subproject `WORKSPACE` uses any
repositories that embedding project does not.
Bright side: building C project is much faster;
no need to download closure, go and JDK...
* Update
* fix ifdef style
* get back to fine-compiler-version-based-macros (use Hedley)
* fix q=0 histogram collection for very long copy/insert commands
By default CMake checks both for C and C++ compilers, while the latter
is not needed. Setting the list of languages to just "C" in the call to
project() removes the unneeded check.
Update
* make the zopflification aware of `NDIRECT`, `NPOSTFIX`
(better compression in `font` mode)
* add small and simple decoder tool
* fix typo
* Java: wrapper: make decoder channel more async-friendly
Ramp up version to 1.0.3 / 1.0.3
* New feature: "Large Window Brotli"
By setting special encoder/decoder flag it is now possible to extend
LZ-window up to 30 bits; though produced stream will not be RFC7932
compliant.
Added new dictionary generator - "DSH". It combines speed of "Sieve"
and quality of "DM". Plus utilities to prepare train corpora
(remove unique strings).
Improved compression ratio: now two sub-blocks could be stitched:
the last copy command could be extended to span the next sub-block.
Fixed compression ineffectiveness caused by floating numbers rounding and
wrong cost heuristic.
Other C changes:
- combined / moved `context.h` to `common`
- moved transforms to `common`
- unified some aspects of code formatting
- added an abstraction for encoder (static) dictionary
- moved default allocator/deallocator functions to `common`
brotli CLI:
- window size is auto-adjusted if not specified explicitly
Java:
- added "eager" decoding both to JNI wrapper and pure decoder
- huge speed-up of `DictionaryData` initialization
* Add dictionaryless compressed dictionary
* Fix `sources.lst`
* Fix `sources.lst` and add a note that `libtool` is also required.
* Update setup.py
* Fix `EagerStreamTest`
* Fix BUILD file
* Add missing `libdivsufsort` dependency
* Fix "unused parameter" warning.
* Update go and closure bazel rules
* Follow the new bazel go rules guide
* Swap go & closure rules initialization
* Update bazel to 0.10.0 in appveyor build
According to the format specification regarding complex prefix codes:
> If there are at least two non-zero code lengths, any trailing zero
> code lengths are omitted, i.e., the last code length in the
> sequence must be non-zero. In this case, the sum of (32 >> code
> length) over all the non-zero code lengths must equal to 32.
> If the lengths have been read for the entire code length alphabet
> and there was only one non-zero code length, then the prefix code
> has one symbol whose code has zero length.
The script does not handle a case where there is just 1 non-zero code
length where the sum rule doesn't apply, which causes a StopIteration
exception when it attempts to read past the list boundaries.
An example of such file is tests/testdata/mapsdatazrh.compressed. I made
sure this change doesn't break anything by processing all *.compressed
files from the testdata folder with no thrown exceptions.
Missed this in my previous tests. Sorry for that.
On BSDs, both bc and sed are part of the base operating system. For sed this results in an error as the check construct (--version) is a GNU-ism and only works for GNU sed, not for bsd sed.
Similarly, BSD sed does not take parameters after the filename(s) operated on. Moving `-i` to the front fixes that. `-r` is provided for GNU compat in BSD sed as an alias of `-E`. The `-i` option in BSD sed requires an extension to work in-place.
(thank you for picking up the nginx module too!)
* Use Clang-5.0
* Disable unholy ASAN leak detector (to unbreak build)
* Reduce build matrix and use faster env, where compiler version is not important
* Add autotools build to Travis matrix
When using autotools to build the binary and libraries, the resulting libraries don't link `brotlicommon` or `m`.
This was detected when building cURL 7.57.0 which has now has brotli support. During configure it was failing
```
checking run-time libs availability... failed
configure: error: one or more libs available at link-time are not available run-time. Libs used at link-time: -lbrotlidec -lz -L/usr/local/lib
```
inspection of config.log showed missing symbols from libbrotlicommon as the cause.
This patch results in the encryption and decryption libs to be properly linked against libbrotlicommon and libm.
