From 0de26fd78e1fc0597c0ed840694ac8612cccfeeb Mon Sep 17 00:00:00 2001 From: Letu Ren Date: Wed, 27 Dec 2023 12:06:17 +0800 Subject: [PATCH] Add zlib-ng as an alternative zlib implementation Zlib-ng is zlib replacement with optimizations for "next generation" systems. Its optimization may benifits image library decode and encode speed such as libpng. In our tests, if using zlib-ng and libpng combination on a x86_64 machine with AVX2, the time of `imdecode` amd `imencode` will drop 20% approximately. This patch enables zlib-ng's optimization if `CV_DISABLE_OPTIMIZATION` is OFF. Since Zlib-ng can dispatch intrinsics on the fly, port work is much easier.

The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a +lower threshold for code change. + +zlib has a long history and is incredibly portable, even supporting many systems that predate the Internet.
+That is great, but it can complicate further development and maintainability. The zlib code contains many workarounds +for really old compilers or to accommodate systems with limitations such as operating in a 16-bit environment. + +Many of these workarounds are only maintenance burdens, some of them are pretty huge code-wise. With many workarounds +cluttered throughout the code, it makes it harder for new programmers with an idea/interest for zlib to contribute. + +I decided to make a fork, merge all the Intel optimizations, some of the Cloudflare optimizations, plus a couple other +smaller patches. Then started cleaning out workarounds, various dead code, all contrib and example code.
+The result is a better performing and easier to maintain zlib-ng. + +A lot of improvements have gone into zlib-ng since its start, and numerous people and companies have contributed both +small and big improvements, or valuable testing. + + +Build +----- +Please read LICENSE.md, it is very simple and very liberal. + +There are two ways to build zlib-ng: + +### Cmake + +To build zlib-ng using the cross-platform makefile generator cmake. + +``` +cmake . +cmake --build . --config Release +ctest --verbose -C Release +``` + +Alternatively, you can use the cmake configuration GUI tool ccmake: + +``` +ccmake . +``` + +### Configure + +To build zlib-ng using the bash configure script: + +``` +./configure +make +make test +``` + +Build Options +------------- + +| CMake | configure | Description | Default | +|:-------------------------|:-------------------------|:--------------------------------------------------------------------------------------|---------| +| ZLIB_COMPAT | --zlib-compat | Compile with zlib compatible API | OFF | +| ZLIB_ENABLE_TESTS | | Build test binaries | ON | +| WITH_GZFILEOP | --without-gzfileops | Compile with support for gzFile related functions | ON | +| WITH_OPTIM | --without-optimizations | Build with optimisations | ON | +| WITH_NEW_STRATEGIES | --without-new-strategies | Use new strategies | ON | +| WITH_NATIVE_INSTRUCTIONS | | Compiles with full instruction set supported on this host (gcc/clang -march=native) | OFF | +| WITH_SANITIZER | | Build with sanitizer (memory, address, undefined) | OFF | +| WITH_GTEST | | Build gtest_zlib | ON | +| WITH_FUZZERS | | Build test/fuzz | OFF | +| WITH_BENCHMARKS | | Build test/benchmarks | OFF | +| WITH_MAINTAINER_WARNINGS | | Build with project maintainer warnings | OFF | +| WITH_CODE_COVERAGE | | Enable code coverage reporting | OFF | + + +Install +------- + +WARNING: We do not recommend manually installing unless you really know what you are doing, because this can +potentially override the system default zlib library, and any incompatibility or wrong configuration of zlib-ng +can make the whole system unusable, requiring recovery or reinstall. +If you still want a manual install, we recommend using the /opt/ path prefix. + +For Linux distros, an alternative way to use zlib-ng (if compiled in zlib-compat mode) instead of zlib, is through +the use of the _LD_PRELOAD_ environment variable. If the program is dynamically linked with zlib, then the program +will temporarily attempt to use zlib-ng instead, without risking system-wide instability. + +``` +LD_PRELOAD=/opt/zlib-ng/libz.so.1.2.13.zlib-ng /usr/bin/program +``` + +### Cmake + +To install zlib-ng system-wide using cmake: + +```sh or powershell +cmake --build . --target install +``` + +### Configure + +To install zlib-ng system-wide using the configure script: + +```sh +make install +``` + +### CPack + +After building with cmake, an installation package can be created using cpack. By default a tgz package is created, +but you can append `-G ` to each command to generate alternative packages types (TGZ, ZIP, RPM, DEB).

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.
