##
Frequently Asked Questions about zlib
If your question is not there, please check the zlib home page
http://zlib.net/ which may have more recent information.
The lastest zlib FAQ is at http://zlib.net/zlib_faq.html
1. Is zlib Y2K-compliant?
Yes. zlib doesn't handle dates.
2. Where can I get a Windows DLL version?
The zlib sources can be compiled without change to produce a DLL. See the
file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the
precompiled DLL are found in the zlib web site at http://zlib.net/ .
3. Where can I get a Visual Basic interface to zlib?
See
* http://marknelson.us/1997/01/01/zlib-engine/
* win32/DLL_FAQ.txt in the zlib distribution
4. compress() returns Z_BUF_ERROR.
Make sure that before the call of compress(), the length of the compressed
buffer is equal to the available size of the compressed buffer and not
zero. For Visual Basic, check that this parameter is passed by reference
("as any"), not by value ("as long").
5. deflate() or inflate() returns Z_BUF_ERROR.
Before making the call, make sure that avail_in and avail_out are not zero.
When setting the parameter flush equal to Z_FINISH, also make sure that
avail_out is big enough to allow processing all pending input. Note that a
Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
made with more input or output space. A Z_BUF_ERROR may in fact be
unavoidable depending on how the functions are used, since it is not
possible to tell whether or not there is more output pending when
strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a
heavily annotated example.
6. Where's the zlib documentation (man pages, etc.)?
It's in zlib.h . Examples of zlib usage are in the files test/example.c
and test/minigzip.c, with more in examples/ .
7. Why don't you use GNU autoconf or libtool or ...?
Because we would like to keep zlib as a very small and simple package.
zlib is rather portable and doesn't need much configuration.
8. I found a bug in zlib.
Most of the time, such problems are due to an incorrect usage of zlib.
Please try to reproduce the problem with a small program and send the
corresponding source to us at zlib@gzip.org . Do not send multi-megabyte
data files without prior agreement.
9. Why do I get "undefined reference to gzputc"?
If "make test" produces something like
example.o(.text+0x154): undefined reference to `gzputc'
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
/usr/X11R6/lib. Remove any old versions, then do "make install".
10. I need a Delphi interface to zlib.
See the contrib/delphi directory in the zlib distribution.
11. Can zlib handle .zip archives?
Not by itself, no. See the directory contrib/minizip in the zlib
distribution.
12. Can zlib handle .Z files?
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
the code of uncompress on your own.
13. How can I make a Unix shared library?
By default a shared (and a static) library is built for Unix. So:
make distclean
./configure
make
14. How do I install a shared zlib library on Unix?
After the above, then:
make install
However, many flavors of Unix come with a shared zlib already installed.
Before going to the trouble of compiling a shared version of zlib and
trying to install it, you may want to check if it's already there! If you
can #include <zlib.h>, it's there. The -lz option will probably link to
it. You can check the version at the top of zlib.h or with the
ZLIB_VERSION symbol defined in zlib.h .
15. I have a question about OttoPDF.
We are not the authors of OttoPDF. The real author is on the OttoPDF web
site: Joel Hainley, jhainley@myndkryme.com.
16. Can zlib decode Flate data in an Adobe PDF file?
Yes. See http://www.pdflib.com/ . To modify PDF forms, see
http://sourceforge.net/projects/acroformtool/ .
17. Why am I getting this "register_frame_info not found" error on Solaris?
After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
generates an error such as:
ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
symbol __register_frame_info: referenced symbol not found
The symbol __register_frame_info is not part of zlib, it is generated by
the C compiler (cc or gcc). You must recompile applications using zlib
which have this problem. This problem is specific to Solaris. See
http://www.sunfreeware.com for Solaris versions of zlib and applications
using zlib.
18. Why does gzip give an error on a file I make with compress/deflate?
The compress and deflate functions produce data in the zlib format, which
is different and incompatible with the gzip format. The gz* functions in
zlib on the other hand use the gzip format. Both the zlib and gzip formats
use the same compressed data format internally, but have different headers
and trailers around the compressed data.
19. Ok, so why are there two different formats?
The gzip format was designed to retain the directory information about a
single file, such as the name and last modification date. The zlib format
on the other hand was designed for in-memory and communication channel
applications, and has a much more compact header and trailer and uses a
faster integrity check than gzip.
20. Well that's nice, but how do I make a gzip file in memory?
You can request that deflate write the gzip format instead of the zlib
format using deflateInit2(). You can also request that inflate decode the
gzip format using inflateInit2(). Read zlib.h for more details.
21. Is zlib thread-safe?
Yes. However any library routines that zlib uses and any application-
provided memory allocation routines must also be thread-safe. zlib's gz*
functions use stdio library routines, and most of zlib's functions use the
library memory allocation routines by default. zlib's *Init* functions
allow for the application to provide custom memory allocation routines.
Of course, you should only operate on any given zlib or gzip stream from a
single thread at a time.
22. Can I use zlib in my commercial application?
Yes. Please read the license in zlib.h.
23. Is zlib under the GNU license?
No. Please read the license in zlib.h.
24. The license says that altered source versions must be "plainly marked". So
what exactly do I need to do to meet that requirement?
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
particular, the final version number needs to be changed to "f", and an
identification string should be appended to ZLIB_VERSION. Version numbers
x.x.x.f are reserved for modifications to zlib by others than the zlib
maintainers. For example, if the version of the base zlib you are altering
is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
update the version strings in deflate.c and inftrees.c.
For altered source distributions, you should also note the origin and
nature of the changes in zlib.h, as well as in ChangeLog and README, along
with the dates of the alterations. The origin should include at least your
name (or your company's name), and an email address to contact for help or
issues with the library.
Note that distributing a compiled zlib library along with zlib.h and
zconf.h is also a source distribution, and so you should change
ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
in zlib.h as you would for a full source distribution.
25. Will zlib work on a big-endian or little-endian architecture, and can I
exchange compressed data between them?
Yes and yes.
26. Will zlib work on a 64-bit machine?
Yes. It has been tested on 64-bit machines, and has no dependence on any
data types being limited to 32-bits in length. If you have any
difficulties, please provide a complete problem report to zlib@gzip.org
27. Will zlib decompress data from the PKWare Data Compression Library?
No. The PKWare DCL uses a completely different compressed data format than
does PKZIP and zlib. However, you can look in zlib's contrib/blast
directory for a possible solution to your problem.
28. Can I access data randomly in a compressed stream?
No, not without some preparation. If when compressing you periodically use
Z_FULL_FLUSH, carefully write all the pending data at those points, and
keep an index of those locations, then you can start decompression at those
points. You have to be careful to not use Z_FULL_FLUSH too often, since it
can significantly degrade compression. Alternatively, you can scan a
deflate stream once to generate an index, and then use that index for
random access. See examples/zran.c .
29. Does zlib work on MVS, OS/390, CICS, etc.?
It has in the past, but we have not heard of any recent evidence. There
were working ports of zlib 1.1.4 to MVS, but those links no longer work.
If you know of recent, successful applications of zlib on these operating
systems, please let us know. Thanks.
30. Is there some simpler, easier to read version of inflate I can look at to
understand the deflate format?
First off, you should read RFC 1951. Second, yes. Look in zlib's
contrib/puff directory.
31. Does zlib infringe on any patents?
As far as we know, no. In fact, that was originally the whole point behind
zlib. Look here for some more information:
http://www.gzip.org/#faq11
32. Can zlib work with greater than 4 GB of data?
Yes. inflate() and deflate() will process any amount of data correctly.
Each call of inflate() or deflate() is limited to input and output chunks
of the maximum value that can be stored in the compiler's "unsigned int"
type, but there is no limit to the number of chunks. Note however that the
strm.total_in and strm_total_out counters may be limited to 4 GB. These
counters are provided as a convenience and are not used internally by
inflate() or deflate(). The application can easily set up its own counters
updated after each call of inflate() or deflate() to count beyond 4 GB.
compress() and uncompress() may be limited to 4 GB, since they operate in a
single call. gzseek() and gztell() may be limited to 4 GB depending on how
zlib is compiled. See the zlibCompileFlags() function in zlib.h.
The word "may" appears several times above since there is a 4 GB limit only
if the compiler's "long" type is 32 bits. If the compiler's "long" type is
64 bits, then the limit is 16 exabytes.
33. Does zlib have any security vulnerabilities?
The only one that we are aware of is potentially in gzprintf(). If zlib is
compiled to use sprintf() or vsprintf(), then there is no protection
against a buffer overflow of an 8K string space (or other value as set by
gzbuffer()), other than the caller of gzprintf() assuring that the output
will not exceed 8K. On the other hand, if zlib is compiled to use
snprintf() or vsnprintf(), which should normally be the case, then there is
no vulnerability. The ./configure script will display warnings if an
insecure variation of sprintf() will be used by gzprintf(). Also the
zlibCompileFlags() function will return information on what variant of
sprintf() is used by gzprintf().
If you don't have snprintf() or vsnprintf() and would like one, you can
find a portable implementation here:
http://www.ijs.si/software/snprintf/
Note that you should be using the most recent version of zlib. Versions
1.1.3 and before were subject to a double-free vulnerability, and versions
1.2.1 and 1.2.2 were subject to an access exception when decompressing
invalid compressed data.
34. Is there a Java version of zlib?
Probably what you want is to use zlib in Java. zlib is already included
as part of the Java SDK in the java.util.zip package. If you really want
a version of zlib written in the Java language, look on the zlib home
page for links: http://zlib.net/ .
35. I get this or that compiler or source-code scanner warning when I crank it
up to maximally-pedantic. Can't you guys write proper code?
Many years ago, we gave up attempting to avoid warnings on every compiler
in the universe. It just got to be a waste of time, and some compilers
were downright silly as well as contradicted each other. So now, we simply
make sure that the code always works.
36. Valgrind (or some similar memory access checker) says that deflate is
performing a conditional jump that depends on an uninitialized value.
Isn't that a bug?
No. That is intentional for performance reasons, and the output of deflate
is not affected. This only started showing up recently since zlib 1.2.x
uses malloc() by default for allocations, whereas earlier versions used
calloc(), which zeros out the allocated memory. Even though the code was
correct, versions 1.2.4 and later was changed to not stimulate these
checkers.
37. Will zlib read the (insert any ancient or arcane format here) compressed
data format?
Probably not. Look in the comp.compression FAQ for pointers to various
formats and associated software.
38. How can I encrypt/decrypt zip files with zlib?
zlib doesn't support encryption. The original PKZIP encryption is very
weak and can be broken with freely available programs. To get strong
encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib
compression. For PKZIP compatible "encryption", look at
http://www.info-zip.org/
39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
"gzip" is the gzip format, and "deflate" is the zlib format. They should
probably have called the second one "zlib" instead to avoid confusion with
the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
correctly points to the zlib specification in RFC 1950 for the "deflate"
transfer encoding, there have been reports of servers and browsers that
incorrectly produce or expect raw deflate data per the deflate
specification in RFC 1951, most notably Microsoft. So even though the
"deflate" transfer encoding using the zlib format would be the more
efficient approach (and in fact exactly what the zlib format was designed
for), using the "gzip" transfer encoding is probably more reliable due to
an unfortunate choice of name on the part of the HTTP 1.1 authors.
Bottom line: use the gzip format for HTTP 1.1 encoding.
40. Does zlib support the new "Deflate64" format introduced by PKWare?
No. PKWare has apparently decided to keep that format proprietary, since
they have not documented it as they have previous compression formats. In
any case, the compression improvements are so modest compared to other more
modern approaches, that it's not worth the effort to implement.
41. I'm having a problem with the zip functions in zlib, can you help?
There are no zip functions in zlib. You are probably using minizip by
Giles Vollant, which is found in the contrib directory of zlib. It is not
part of zlib. In fact none of the stuff in contrib is part of zlib. The
files in there are not supported by the zlib authors. You need to contact
the authors of the respective contribution for help.
42. The match.asm code in contrib is under the GNU General Public License.
Since it's part of zlib, doesn't that mean that all of zlib falls under the
GNU GPL?
No. The files in contrib are not part of zlib. They were contributed by
other authors and are provided as a convenience to the user within the zlib
distribution. Each item in contrib has its own license.
43. Is zlib subject to export controls? What is its ECCN?
zlib is not subject to export controls, and so is classified as EAR99.
44. Can you please sign these lengthy legal documents and fax them back to us
so that we can use your software in our product?
No. Go away. Shoo.

Fork Motivation
---------------------------
The motivation for this fork was due to seeing several 3rd party
contributions containing new optimizations not getting implemented
into the official zlib repository.
Mark Adler has been maintaining zlib for a very long time, and he has
done a great job and hopefully he will continue for a long time yet.
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
lots of systems that predate the Internet. This is great, but it does
complicate further development and maintainability.
The zlib code has numerous workarounds for old compilers that do not
understand ANSI-C 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. For example, the [v]s[n]printf workaround
code has a whopping 8 different implementations just to cater to
various old compilers. With this many workarounds cluttered throughout
the code, new programmers with an idea/interest for zlib will need
to take some time to figure out why all of these seemingly strange
things are used, and how to work within those confines.
So I decided to make a fork, merge all the Intel optimizations, merge
the Cloudflare optimizations that did not conflict, plus a couple
of other smaller patches. Then I started cleaning out workarounds,
various dead code, all contrib and example code as there is little
point in having those in this fork for various reasons.
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.
Please read LICENSE.md, it is very simple and very liberal.
Build
-----
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 | --native | Compiles with full instruction set supported on this host (gcc/clang -march=native) | OFF |
| WITH_SANITIZER | --with-sanitizer | Build with sanitizer (memory, address, undefined) | OFF |
| WITH_FUZZERS | --with-fuzzers | Build test/fuzz | 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 zlib-ng will temporarily be used instead by the program,
without risking system-wide instability.
```
LD_PRELOAD=/opt/zlib-ng/libz.so.1.2.11.zlib-ng /usr/bin/program
```
### Cmake
To install zlib-ng system-wide using cmake:
```
cmake --build . --target install
```
### Configure
To install zlib-ng system-wide using the configure script:
```
make install
```
Contributing
------------
Zlib-ng is a aiming to be open to contributions, and we would be
delighted to receive pull requests on github.
Just remember that any code you submit must be your own and it must
be zlib licensed.
Help with testing and reviewing of pull requests etc is also very
much appreciated.
If you are interested in contributing, please consider joining our
IRC channel #zlib-ng on the Freenode IRC network.
Acknowledgments
----------------
Thanks to Servebolt.com for sponsoring my maintainership of zlib-ng.
Thanks go out to all the people and companies who have taken the time
to contribute code reviews, testing and/or patches. Zlib-ng would not
have been nearly as good without you.
The deflate format used by zlib was defined by Phil Katz.
The deflate and zlib specifications were written by L. Peter Deutsch.
zlib was originally created by Jean-loup Gailly (compression)
and Mark Adler (decompression).

/* Adler32 for POWER8 using VSX instructions.
* Copyright (C) 2020 IBM Corporation
* Author: Rogerio Alves <rcardoso@linux.ibm.com>
* For conditions of distribution and use, see copyright notice in zlib.h
*
* Calculate adler32 checksum for 16 bytes at once using POWER8+ VSX (vector)
* instructions.
*
* If adler32 do 1 byte at time on the first iteration s1 is s1_0 (_n means
* iteration n) is the initial value of adler - at start _0 is 1 unless
* adler initial value is different than 1. So s1_1 = s1_0 + c[0] after
* the first calculation. For the iteration s1_2 = s1_1 + c[1] and so on.
* Hence, for iteration N, s1_N = s1_(N-1) + c[N] is the value of s1 on
* after iteration N.
*
* Therefore, for s2 and iteration N, s2_N = s2_0 + N*s1_N + N*c[0] +
* N-1*c[1] + ... + c[N]
*
* In a more general way:
*
* s1_N = s1_0 + sum(i=1 to N)c[i]
* s2_N = s2_0 + N*s1 + sum (i=1 to N)(N-i+1)*c[i]
*
* Where s1_N, s2_N are the values for s1, s2 after N iterations. So if we
* can process N-bit at time we can do this at once.
*
* Since VSX can support 16-bit vector instructions, we can process
* 16-bit at time using N = 16 we have:
*
* s1 = s1_16 = s1_(16-1) + c[16] = s1_0 + sum(i=1 to 16)c[i]
* s2 = s2_16 = s2_0 + 16*s1 + sum(i=1 to 16)(16-i+1)*c[i]
*
* After the first iteration we calculate the adler32 checksum for 16 bytes.
*
* For more background about adler32 please check the RFC:
* https://www.ietf.org/rfc/rfc1950.txt

# Introduction
This directory contains SystemZ deflate hardware acceleration support.
It can be enabled using the following build commands:
$ ./configure --with-dfltcc-deflate --with-dfltcc-inflate
$ make
or
$ cmake -DWITH_DFLTCC_DEFLATE=1 -DWITH_DFLTCC_INFLATE=1 .
$ make
When built like this, zlib-ng would compress using hardware on level 1,
and using software on all other levels. Decompression will always happen
in hardware. In order to enable hardware compression for levels 1-6
(i.e. to make it used by default) one could add
`-DDFLTCC_LEVEL_MASK=0x7e` to CFLAGS when building zlib-ng.
SystemZ deflate hardware acceleration is available on [IBM z15](
https://www.ibm.com/products/z15) and newer machines under the name [
"Integrated Accelerator for zEnterprise Data Compression"](
https://www.ibm.com/support/z-content-solutions/compression/). The
programming interface to it is a machine instruction called DEFLATE
CONVERSION CALL (DFLTCC). It is documented in Chapter 26 of [Principles
of Operation](http://publibfp.dhe.ibm.com/epubs/pdf/a227832c.pdf). Both
the code and the rest of this document refer to this feature simply as
"DFLTCC".
# Performance
Performance figures are published [here](
https://github.com/iii-i/zlib-ng/wiki/Performance-with-dfltcc-patch-applied-and-dfltcc-support-built-on-dfltcc-enabled-machine
). The compression speed-up can be as high as 110x and the decompression
speed-up can be as high as 15x.
# Limitations
Two DFLTCC compression calls with identical inputs are not guaranteed to
produce identical outputs. Therefore care should be taken when using
hardware compression when reproducible results are desired. In
particular, zlib-ng-specific `zng_deflateSetParams` call allows setting
`Z_DEFLATE_REPRODUCIBLE` parameter, which disables DFLTCC support for a
particular stream.
DFLTCC does not support every single zlib-ng feature, in particular:
* `inflate(Z_BLOCK)` and `inflate(Z_TREES)`
* `inflateMark()`
* `inflatePrime()`
* `inflateSyncPoint()`
When used, these functions will either switch to software, or, in case
this is not possible, gracefully fail.
# Code structure
All SystemZ-specific code lives in `arch/s390` directory and is
integrated with the rest of zlib-ng using hook macros.
## Hook macros
DFLTCC takes as arguments a parameter block, an input buffer, an output
buffer and a window. `ZALLOC_STATE()`, `ZFREE_STATE()`, `ZCOPY_STATE()`,
`ZALLOC_WINDOW()` and `TRY_FREE_WINDOW()` macros encapsulate allocation
details for the parameter block (which is allocated alongside zlib-ng
state) and the window (which must be page-aligned).
While inflate software and hardware window formats match, this is not
the case for deflate. Therefore, `deflateSetDictionary()` and
`deflateGetDictionary()` need special handling, which is triggered using
`DEFLATE_SET_DICTIONARY_HOOK()` and `DEFLATE_GET_DICTIONARY_HOOK()`
macros.
`deflateResetKeep()` and `inflateResetKeep()` update the DFLTCC
parameter block using `DEFLATE_RESET_KEEP_HOOK()` and
`INFLATE_RESET_KEEP_HOOK()` macros.
`INFLATE_PRIME_HOOK()`, `INFLATE_MARK_HOOK()` and
`INFLATE_SYNC_POINT_HOOK()` macros make the respective unsupported
calls gracefully fail.
`DEFLATE_PARAMS_HOOK()` implements switching between hardware and
software compression mid-stream using `deflateParams()`. Switching
normally entails flushing the current block, which might not be possible
in low memory situations. `deflateParams()` uses `DEFLATE_DONE()` hook
in order to detect and gracefully handle such situations.
The algorithm implemented in hardware has different compression ratio
than the one implemented in software. `DEFLATE_BOUND_ADJUST_COMPLEN()`
and `DEFLATE_NEED_CONSERVATIVE_BOUND()` macros make `deflateBound()`
return the correct results for the hardware implementation.
Actual compression and decompression are handled by `DEFLATE_HOOK()` and
`INFLATE_TYPEDO_HOOK()` macros. Since inflation with DFLTCC manages the
window on its own, calling `updatewindow()` is suppressed using
`INFLATE_NEED_UPDATEWINDOW()` macro.
In addition to compression, DFLTCC computes CRC-32 and Adler-32
checksums, therefore, whenever it's used, software checksumming is
suppressed using `DEFLATE_NEED_CHECKSUM()` and `INFLATE_NEED_CHECKSUM()`
macros.
While software always produces reproducible compression results, this
is not the case for DFLTCC. Therefore, zlib-ng users are given the
ability to specify whether or not reproducible compression results
are required. While it is always possible to specify this setting
before the compression begins, it is not always possible to do so in
the middle of a deflate stream - the exact conditions for that are
determined by `DEFLATE_CAN_SET_REPRODUCIBLE()` macro.
## SystemZ-specific code
When zlib-ng is built with DFLTCC, the hooks described above are
converted to calls to functions, which are implemented in
`arch/s390/dfltcc_*` files. The functions can be grouped in three broad
categories:
* Base DFLTCC support, e.g. wrapping the machine instruction -
`dfltcc()` and allocating aligned memory - `dfltcc_alloc_state()`.
* Translating between software and hardware data formats, e.g.
`dfltcc_deflate_set_dictionary()`.
* Translating between software and hardware state machines, e.g.
`dfltcc_deflate()` and `dfltcc_inflate()`.
The functions from the first two categories are fairly simple, however,
various quirks in both software and hardware state machines make the
functions from the third category quite complicated.
### `dfltcc_deflate()` function
This function is called by `deflate()` and has the following
responsibilities:
* Checking whether DFLTCC can be used with the current stream. If this
is not the case, then it returns `0`, making `deflate()` use some
other function in order to compress in software. Otherwise it returns
`1`.
* Block management and Huffman table generation. DFLTCC ends blocks only
when explicitly instructed to do so by the software. Furthermore,
whether to use fixed or dynamic Huffman tables must also be determined
by the software. Since looking at data in order to gather statistics
would negate performance benefits, the following approach is used: the
first `DFLTCC_FIRST_FHT_BLOCK_SIZE` bytes are placed into a fixed
block, and every next `DFLTCC_BLOCK_SIZE` bytes are placed into
dynamic blocks.
* Writing EOBS. Block Closing Control bit in the parameter block
instructs DFLTCC to write EOBS, however, certain conditions need to be
met: input data length must be non-zero or Continuation Flag must be
set. To put this in simpler terms, DFLTCC will silently refuse to
write EOBS if this is the only thing that it is asked to do. Since the
code has to be able to emit EOBS in software anyway, in order to avoid
tricky corner cases Block Closing Control is never used. Whether to
write EOBS is instead controlled by `soft_bcc` variable.
* Triggering block post-processing. Depending on flush mode, `deflate()`
must perform various additional actions when a block or a stream ends.
`dfltcc_deflate()` informs `deflate()` about this using
`block_state *result` parameter.
* Converting software state fields into hardware parameter block fields,
and vice versa. For example, `wrap` and Check Value Type or `bi_valid`
and Sub-Byte Boundary. Certain fields cannot be translated and must
persist untouched in the parameter block between calls, for example,
Continuation Flag or Continuation State Buffer.
* Handling flush modes and low-memory situations. These aspects are
quite intertwined and pervasive. The general idea here is that the
code must not do anything in software - whether explicitly by e.g.
calling `send_eobs()`, or implicitly - by returning to `deflate()`
with certain return and `*result` values, when Continuation Flag is
set.
* Ending streams. When a new block is started and flush mode is
`Z_FINISH`, Block Header Final parameter block bit is used to mark
this block as final. However, sometimes an empty final block is
needed, and, unfortunately, just like with EOBS, DFLTCC will silently
refuse to do this. The general idea of DFLTCC implementation is to
rely as much as possible on the existing code. Here in order to do
this, the code pretends that it does not support DFLTCC, which makes
`deflate()` call a software compression function, which writes an
empty final block. Whether this is required is controlled by
`need_empty_block` variable.
* Error handling. This is simply converting
Operation-Ending-Supplemental Code to string. Errors can only happen
due to things like memory corruption, and therefore they don't affect
the `deflate()` return code.
### `dfltcc_inflate()` function
This function is called by `inflate()` from the `TYPEDO` state (that is,
when all the metadata is parsed and the stream is positioned at the type
bits of deflate block header) and it's responsible for the following:
* Falling back to software when flush mode is `Z_BLOCK` or `Z_TREES`.
Unfortunately, there is no way to ask DFLTCC to stop decompressing on
block or tree boundary.
* `inflate()` decompression loop management. This is controlled using
the return value, which can be either `DFLTCC_INFLATE_BREAK` or
`DFLTCC_INFLATE_CONTINUE`.
* Converting software state fields into hardware parameter block fields,
and vice versa. For example, `whave` and History Length or `wnext` and
History Offset.
* Ending streams. This instructs `inflate()` to return `Z_STREAM_END`
and is controlled by `last` state field.
* Error handling. Like deflate, error handling comprises
Operation-Ending-Supplemental Code to string conversion. Unlike
deflate, errors may happen due to bad inputs, therefore they are
propagated to `inflate()` by setting `mode` field to `MEM` or `BAD`.
# Testing
Given complexity of DFLTCC machine instruction, it is not clear whether
QEMU TCG will ever support it. At the time of writing, one has to have
access to an IBM z15+ VM or LPAR in order to test DFLTCC support. Since
DFLTCC is a non-privileged instruction, neither special VM/LPAR
configuration nor root are required.
Still, zlib-ng CI has a few QEMU TCG-based configurations that check
whether fallback to software is working.

only reads from those pointers. So long as this code remains isolated in
