dgp bc9dca8ca6 Docs for Tcl_CreateChannelHandler() state that the registered handler proc
will be called back with a mask value. "Mask is an integer mask indicating
which of the requested conditions actually exists for the channel; it will
contain ***a subset of the bits from the mask argument*** to
Tcl_CreateChannelHandler when the handler was created." (emhpasis added).

Tcl_NotifyChannel is not honoring this.  It passes a mask value that may
contain bits not in common with the mask argument to T_CCH().

This commit is a one-liner patch adding in the masking step to make things
behave as documented.  Thanks to apn for digging this out.  (In combination
with other questionable code, this led to a hang in test http-4.6 on Windows)

Tcl_NotifyChannel() has had this error in all of recorded Tcl history.
It's hard to imagine any code dependent on it though.  If any exists, it
can be revised to pass the mask value it truly needs to T_CCH() and end up
with code suitable both before and after this change.

If you concur, please merge to core-8-5-branch, and I'll take it from there.

dgp c93483448e Accommodate the "udp" package, and any other Tcl package that expects a
[read] on a channel @ EOF to attempt another pass through the channel drivers
instead of immediately returning an empty string.  Correcting this misbehavior
appears too disruptive in a patch release to a long stable branch.

dgp c6eb718dfd An alternative implementation of [chan copy] that operates in precisely
those circumstances where the incumbent implementation is known to perform
a byte-for-byte copy from input channel to output channel.

In that case, the new implementation ceases the activity of copying every
byte from buffer to buffer to buffer to buffer to effect the copy.  Instead
it arranges for the very same buffer the input channel read driver read into
to be the buffer the output channel write driver writes out from.  No data
copying (or even examining) at all.  When the proper conditions apply, this
ought to be noticeably faster.

dgp: Isn't the better way to make it obvious the values

For example, [testchmod 0o777 $path] ?

Really seems like a bad idea to me to introduce *more*
incompatibilities for the planned conversion for 
having the value 0777 stop meaning 255 and start
meaning 777 in Tcl 9.

demanded by Tcl_ExternalToUtf().  (Thanks for finding that, aku!)
Fix the factorPtr management.  It was just totaly wrong. The factor should
be a ratio of the record of bytes read to the record of chars read.
With those fixes, new test io-12.6 covers the "too many chars" code.

andreask ba7b49d9c4 Fixed a tricky interaction of IO system and encodings which could
result in a panic.

The relevant function is ReadChars() (short RC in the following).

When the encoding and translation transforms deliver more characters
than were requested the iterative algorithm used by RC reduces the
value of "dstLimit" (= the number of bytes allowed to be copied into
the destination buffer) to force the next round to deliver less
characters, hopefully the number requested.

The existing code used the byte located just after the last wanted
character to determine the new limit. The resulting value could
_undershoot_ the best possible limit because Tcl_ExternalToUtf would
effectively reduce this limit further, by TCL_UTF_MAX+1, to have
enough space for a single multi-byte character in the buffer, and a
closing '\0' as well.

One effect of this were additional calls to ReadChars() to retrieve
the characters missed by a call with an undershot limit.

In the limit (sic) however this was also able to cause a full-blown
"Buffer Underflow" panic if the original request was for less than
TCL_UTF_MAX characters (*), and we are using a single-byte encoding
like iso-8859-1. Because then the undershot dstLimit would prevent the
next round from copying anything, and causing it to try and
consolidate the current buffer with the next buffer, thinking that it
had to merge a multi-byte character split across buffer boundaries.

(Ad *) For example because the previous call had undershot already and
left only such a small amount of characters behind!

The basic fix to the problem is to add TCL_UTF_MAX back to the limit,
like is done in all the (three) other places in RC setting a new
one. Note however that this naive fix may generate a new limit which
is the same as the old, or possibly larger. If that happens we act
very conservatively and reduce the limit by only one byte instead.

While I believe that this last conservative approach will never reduce
the limit to TCL_UTF_MAX or less before reaching a state where it
returnds the exact amount of requested characters I still added a
check against this situation anyway, causing a new panic if triggered.

andreask cc63d97f54 Workarounds and fixes for wrapped executables on various platforms
regarding the handling of wrapped dynamic libraries.

The basic flow of operation is to copy such libraries into a temp
file, hand them to the OS loader for processing, and then to delete
them immediately, to prevent them from being accessible to other
executables. On platforms where that is not possible the library is
left in place and things are arranged to delete it on regular process
exit.

An example of the latter are older revisions of HPUX which report that
the file is busy when trying to delete it. Younger revisions of HPUX
have changed to allow the deletion, but are also buggy, the OS loader
mangles its data structures so that a second library loaded in this
manner fails.

More recently it was found that Linux which is usually ok with
deleting the file and gets everything right shows the same trouble as
modern HPUX when the "docker" containerization system is involved, or
more specifically the AUFS in use there. Deleting the loaded library
file mangles data structures and breaks loading of the following
libraries. For a demonstration which does not involve Tcl at all see
the ticket

     https://github.com/dotcloud/docker/issues/1911

in the docker tracker.

This of course breaks the use of wrapped executables within docker
containers.

This commit introduces the function TclSkipUnlink() which centralizes
the handling of such exceptions to unlinking the library after unload,
and provides code handling the known cases. IOW HPUX is generally
forced to not unlink, and ditto when we detect that the copied library
file resides within an AUFS.

The latter must however be explicitly activated by setting the define
-DTCL_TEMPLOAD_NO_UNLINK during build. We still need proper configure
tests to set it on the relevant platforms (i.e. Linux).

The AUFS detection and handling can be overridden by the environment
variable TCL_TEMPLOAD_NO_UNLINK which can force the behaviour either
way (skip or not). In case the user knows best, or wishes to test if
the problem with AUFS has been fixed.

infinite loop (nested unstacking?!  whoa.), so revised the test to one

Also moves overflow checking to TclAppendBytesToByteArray() and adds
the ability to call TABTBA() with bytes==NULL, for appending unspecified
bytes.  That is, the string grows, but the new bytes are of undetermined
value.  Like Tcl_NewByteArrayObj(NULL, length) this option is useful
for manipulating buffers.  The TABTBA growth algorithm is also enhanced
a bit, copying over a fuller implementation from GrowStringBuffer()
in tclStringObj.c

Better allow iterNum and iterMax to grow to ssize_t (or size_t) in Tcl 9 (or 8.x, why not?). 
Usage of "long" in public API causes interoperability problems between Cygwin64 and Win64 (probably no-one cares except me).

jan.nijtmans 878c0cff52 Cherrypick [87d1313df3] from trunk:
Workaround for [http://sourceforge.net/p/mingw/bugs/2065/|MinGW bug #2065]. 
Both MinGW and MinGW-w64 (32-bit) are affected. 
Even though Win64 is not affected, adding -static-libgcc doesn't harm there, and we don't want to distrubute additional dll's with MinGW-compiled Tcl anyway.

itself.

dgp 64bf3c8f4a More progress. NR-enable [interp] and [$slave], completely with
invokehidden subcommand.  Test suite passes with no errors.
2013-04-11 21:30:40 +00:00
dgp 064f7e5513 More revisions let multi-interp test case work, but at cost of panics
and segfaults.  Pushing the NRE-envelope.
2013-04-11 19:36:37 +00:00
dgp 6597872335 New internal routine TclNRInvoke() - NR-enabled path through the machinery
behind invokehidden commands.
2013-04-11 14:39:56 +00:00
dgp 5044035ec0 merge trunk 2013-04-11 13:35:41 +00:00
dgp 6b17a1e25a Revise TclNREvalObjv so that pre-resolution of the Command by a caller
does not force suppression of exception handling.  Let those be separable
demands.  Aim is to bring TclObjInvoke*() into the fold.

Hit some problem edge cases with differences in strictness of edge cases that
will force a rethink ([string is boolean] is significantly more strict than
Tcl_GetBooleanFromObj).

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.

ZLIB DATA COMPRESSION LIBRARY
zlib 1.2.8 is a general purpose data compression library. All the code is
thread safe. The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (gzip format).
All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
of the library is given in the file test/example.c which also tests that
the library is working correctly. Another example is given in the file
test/minigzip.c. The compression library itself is composed of all source
files in the root directory.
To compile all files and run the test program, follow the instructions given at
the top of Makefile.in. In short "./configure; make test", and if that goes
well, "make install" should work for most flavors of Unix. For Windows, use
one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
make_vms.com.
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
<info@winimage.com> for the Windows DLL version. The zlib home page is
http://zlib.net/ . Before reporting a problem, please check this site to
verify that you have the latest version of zlib; otherwise get the latest
version and check whether the problem still exists or not.
PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
issue of Dr. Dobb's Journal; a copy of the article is available at
http://marknelson.us/1997/01/01/zlib-engine/ .
The changes made in version 1.2.8 are documented in the file ChangeLog.
Unsupported third party contributions are provided in directory contrib/ .
zlib is available in Java using the java.util.zip package, documented at
http://java.sun.com/developer/technicalArticles/Programming/compression/ .
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
at CPAN (Comprehensive Perl Archive Network) sites, including
http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
available in Python 1.5 and later versions, see
http://docs.python.org/library/zlib.html .
zlib is built into tcl: http://wiki.tcl.tk/4610 .
An experimental package to read and write files in .zip format, written on top
of zlib by Gilles Vollant <info@winimage.com>, is available in the
contrib/minizip directory of zlib.
Notes for some targets:
- For Windows DLL versions, please see win32/DLL_FAQ.txt
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
compiler flag). The compiler bug has been reported to SGI.
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
when compiled with cc.
- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
necessary to get gzprintf working correctly. This is done by configure.
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
other compilers. Use "make test" to check your compiler.
- gzdopen is not supported on RISCOS or BEOS.
- For PalmOs, see http://palmzlib.sourceforge.net/
Acknowledgments:
The deflate format used by zlib was defined by Phil Katz. The deflate and
zlib specifications were written by L. Peter Deutsch. Thanks to all the
people who reported problems and suggested various improvements in zlib; they
are too numerous to cite here.

ZLIB version 1.2.8 for AS400 installation instructions
I) From an AS400 *SAVF file:
1) Unpacking archive to an AS400 save file
On the AS400:
_ Create the ZLIB AS400 library:
CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
_ Create a work save file, for example:
CRTSAVF FILE(ZLIB/ZLIBSAVF)
On a PC connected to the target AS400:
_ Unpack the save file image to a PC file "ZLIBSAVF"
_ Upload this file into the save file on the AS400, for example
using ftp in BINARY mode.
2) Populating the ZLIB AS400 source library
On the AS400:
_ Extract the saved objects into the ZLIB AS400 library using:
RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
3) Customize installation:
_ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
according to the comments.
_ Compile this member with:
CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
4) Compile and generate the service program:
_ This can now be done by executing:
CALL PGM(ZLIB/COMPILE)
II) From the original source distribution:
1) On the AS400, create the source library:
CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
2) Create the source files:
CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')
CRTSRCPF FILE(ZLIB/TOOLS) RCDLEN(112) TEXT('ZLIB library control utilities')
3) From the machine hosting the distribution files, upload them (with
FTP in text mode, for example) according to the following table:
Original AS400 AS400 AS400 AS400

4) Continue as in I)3).
Notes: For AS400 ILE RPG programmers, a /copy member defining the ZLIB
API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
Please read comments in this member for more information.
Remember that most foreign textual data are ASCII coded: this
implementation does not handle conversion from/to ASCII, so
text data code conversions must be done explicitely.
Mainly for the reason above, always open zipped files in binary mode.

ZLib for Ada thick binding (ZLib.Ada)
Release 1.3
ZLib.Ada is a thick binding interface to the popular ZLib data
compression library, available at http://www.gzip.org/zlib/.
It provides Ada-style access to the ZLib C library.
Here are the main changes since ZLib.Ada 1.2:
- Attension: ZLib.Read generic routine have a initialization requirement
for Read_Last parameter now. It is a bit incompartible with previous version,
but extends functionality, we could use new parameters Allow_Read_Some and
Flush now.
- Added Is_Open routines to ZLib and ZLib.Streams packages.
- Add pragma Assert to check Stream_Element is 8 bit.
- Fix extraction to buffer with exact known decompressed size. Error reported by
Steve Sangwine.
- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
computers. Patch provided by Pascal Obry.
- Add Status_Error exception definition.
- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
How to build ZLib.Ada under GNAT
You should have the ZLib library already build on your computer, before
building ZLib.Ada. Make the directory of ZLib.Ada sources current and
issue the command:
gnatmake test -largs -L<directory where libz.a is> -lz
Or use the GNAT project file build for GNAT 3.15 or later:
gnatmake -Pzlib.gpr -L<directory where libz.a is>
How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
1. Make a project with all *.ads and *.adb files from the distribution.
2. Build the libz.a library from the ZLib C sources.
3. Rename libz.a to z.lib.
4. Add the library z.lib to the project.
5. Add the libc.lib library from the ObjectAda distribution to the project.
6. Build the executable using test.adb as a main procedure.
How to use ZLib.Ada
The source files test.adb and read.adb are small demo programs that show
the main functionality of ZLib.Ada.
The routines from the package specifications are commented.

This is a patched version of zlib, modified to use
Pentium-Pro-optimized assembly code in the deflation algorithm. The
files changed/added by this patch are:
README.686
match.S
The speedup that this patch provides varies, depending on whether the
compiler used to build the original version of zlib falls afoul of the
PPro's speed traps. My own tests show a speedup of around 10-20% at
the default compression level, and 20-30% using -9, against a version
compiled using gcc 2.7.2.3. Your mileage may vary.
Note that this code has been tailored for the PPro/PII in particular,
and will not perform particuarly well on a Pentium.
If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)
Brian Raiter
breadbox@muppetlabs.com
April, 1998
Added for zlib 1.1.3:
The patches come from
http://www.muppetlabs.com/~breadbox/software/assembly.html
To compile zlib with this asm file, copy match.S to the zlib directory
then do:
CFLAGS="-O3 -DASMV" ./configure
make OBJA=match.o
Update:
I've been ignoring these assembly routines for years, believing that
gcc's generated code had caught up with it sometime around gcc 2.95
and the major rearchitecting of the Pentium 4. However, I recently
learned that, despite what I believed, this code still has some life
in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
faster than the code produced by gcc 4.1.
In acknowledgement of its continuing usefulness, I've altered the
license to match that of the rest of zlib. Share and Enjoy!

* 00 04 82 24 25 8f 80 7f
*
* which decompresses to "AIAIAIAIAIAIA" (without the quotes).

* - First byte is 0 if literals are uncoded or 1 if they are coded. Second
* byte is 4, 5, or 6 for the number of extra bits in the distance code.
* This is the base-2 logarithm of the dictionary size minus six.
*
* - Compressed data is a combination of literals and length/distance pairs
* terminated by an end code. Literals are either Huffman coded or
* uncoded bytes. A length/distance pair is a coded length followed by a
* coded distance to represent a string that occurs earlier in the
* uncompressed data that occurs again at the current location.
*
* - A bit preceding a literal or length/distance pair indicates which comes
* next, 0 for literals, 1 for length/distance.
*
* - If literals are uncoded, then the next eight bits are the literal, in the
* normal bit order in th stream, i.e. no bit-reversal is needed. Similarly,
* no bit reversal is needed for either the length extra bits or the distance
* extra bits.
*
* - Literal bytes are simply written to the output. A length/distance pair is
* an instruction to copy previously uncompressed bytes to the output. The
* copy is from distance bytes back in the output stream, copying for length
* bytes.
*
* - Distances pointing before the beginning of the output data are not
* permitted.
*
* - Overlapped copies, where the length is greater than the distance, are
* allowed and common. For example, a distance of one and a length of 518
* simply copies the last byte 518 times. A distance of four and a length of
* twelve copies the last four bytes three times. A simple forward copy
* ignoring whether the length is greater than the distance or not implements
* this correctly.

{ TCompressionStream compresses data on the fly as data is written to it, and
stores the compressed data to another stream.
TCompressionStream is write-only and strictly sequential. Reading from the
stream will raise an exception. Using Seek to move the stream pointer
will raise an exception.
Output data is cached internally, written to the output stream only when
the internal output buffer is full. All pending output data is flushed
when the stream is destroyed.
The Position property returns the number of uncompressed bytes of
data that have been written to the stream so far.
CompressionRate returns the on-the-fly percentage by which the original
data has been compressed: (1 - (CompressedBytes / UncompressedBytes)) * 100
If raw data size = 100 and compressed data size = 25, the CompressionRate
is 75%
The OnProgress event is called each time the output buffer is filled and
written to the output stream. This is useful for updating a progress
indicator when you are writing a large chunk of data to the compression
stream in a single call.}

{ TDecompressionStream decompresses data on the fly as data is read from it.
Compressed data comes from a separate source stream. TDecompressionStream
is read-only and unidirectional; you can seek forward in the stream, but not
backwards. The special case of setting the stream position to zero is
allowed. Seeking forward decompresses data until the requested position in
the uncompressed data has been reached. Seeking backwards, seeking relative
to the end of the stream, requesting the size of the stream, and writing to
the stream will raise an exception.
The Position property returns the number of bytes of uncompressed data that
have been read from the stream so far.
The OnProgress event is called each time the internal input buffer of
compressed data is exhausted and the next block is read from the input stream.

Overview
========
This directory contains an update to the ZLib interface unit,
distributed by Borland as a Delphi supplemental component.
The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
and is based on zlib version 1.0.4. There are a series of bugs
and security problems associated with that old zlib version, and
we recommend the users to update their ZLib unit.
Summary of modifications
========================
- Improved makefile, adapted to zlib version 1.2.1.
- Some field types from TZStreamRec are changed from Integer to
Longint, for consistency with the zlib.h header, and for 64-bit
readiness.
- The zlib_version constant is updated.
- The new Z_RLE strategy has its corresponding symbolic constant.
- The allocation and deallocation functions and function types
(TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
and _malloc and _free are added as C RTL stubs. As a result,
the original C sources of zlib can be compiled out of the box,
and linked to the ZLib unit.
Suggestions for improvements
============================
Currently, the ZLib unit provides only a limited wrapper around
the zlib library, and much of the original zlib functionality is
missing. Handling compressed file formats like ZIP/GZIP or PNG
cannot be implemented without having this functionality.
Applications that handle these formats are either using their own,
duplicated code, or not using the ZLib unit at all.
Here are a few suggestions:
- Checksum class wrappers around adler32() and crc32(), similar
to the Java classes that implement the java.util.zip.Checksum
interface.
- The ability to read and write raw deflate streams, without the
zlib stream header and trailer. Raw deflate streams are used
in the ZIP file format.
- The ability to read and write gzip streams, used in the GZIP
file format, and normally produced by the gzip program.
- The ability to select a different compression strategy, useful
to PNG and MNG image compression, and to multimedia compression
in general. Besides the compression level
TCompressionLevel = (clNone, clFastest, clDefault, clMax);
which, in fact, could have used the 'z' prefix and avoided
TColor-like symbols
TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
there could be a compression strategy
TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
- ZIP and GZIP stream handling via TStreams.

This directory contains a .Net wrapper class library for the ZLib1.dll
The wrapper includes support for inflating/deflating memory buffers,
.Net streaming wrappers for the gz streams part of zlib, and wrappers
for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
Directory structure:
--------------------
LICENSE_1_0.txt - License file.
readme.txt - This file.
DotZLib.chm - Class library documentation
DotZLib.build - NAnt build file
DotZLib.sln - Microsoft Visual Studio 2003 solution file
DotZLib\*.cs - Source files for the class library
Unit tests:
-----------
The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
To include unit tests in the build, define nunit before building.
Build instructions:
-------------------
1. Using Visual Studio.Net 2003:
Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
you are building the release or debug version of the library. Check
DotZLib/UnitTests.cs for instructions on how to include unit tests in the
build.
2. Using NAnt:
Open a command prompt with access to the build environment and run nant
in the same directory as the DotZLib.build file.
You can define 2 properties on the nant command-line to control the build:
debug={true|false} to toggle between release/debug builds (default=true).
nunit={true|false} to include or esclude unit tests (default=true).
Also the target clean will remove binaries.
Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
or ./DotZLib/bin/debug, depending on whether you are building the release
or debug version of the library.
Examples:
nant -D:debug=false -D:nunit=false
will build a release mode version of the library without unit tests.
nant
will build a debug version of the library with unit tests
nant clean
will remove all previously built files.

/*
strm provides the memory allocation functions and window buffer on input,
and provides information on the unused input on return. For Z_DATA_ERROR
returns, strm will also provide an error message.
in() and out() are the call-back input and output functions. When
inflateBack() needs more input, it calls in(). When inflateBack() has
filled the window with output, or when it completes with data in the
window, it calls out() to write out the data. The application must not
change the provided input until in() is called again or inflateBack()
returns. The application must not change the window/output buffer until
inflateBack() returns.
in() and out() are called with a descriptor parameter provided in the
inflateBack() call. This parameter can be a structure that provides the
information required to do the read or write, as well as accumulated
information on the input and output such as totals and check values.
in() should return zero on failure. out() should return non-zero on
failure. If either in() or out() fails, than inflateBack() returns a
Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
was in() or out() that caused in the error. Otherwise, inflateBack()
returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
error, or Z_MEM_ERROR if it could not allocate memory for the state.
inflateBack() can also return Z_STREAM_ERROR if the input parameters
are not correct, i.e. strm is Z_NULL or the state was not initialized.

/*
Process a set of code lengths to create a canonical Huffman code. The
code lengths are lens[0..codes-1]. Each length corresponds to the
symbols 0..codes-1. The Huffman code is generated by first sorting the
symbols by length from short to long, and retaining the symbol order
for codes with equal lengths. Then the code starts with all zero bits
for the first code of the shortest length, and the codes are integer
increments for the same length, and zeros are appended as the length
increases. For the deflate format, these bits are stored backwards
from their more natural integer increment ordering, and so when the
decoding tables are built in the large loop below, the integer codes
are incremented backwards.
This routine assumes, but does not check, that all of the entries in
lens[] are in the range 0..MAXBITS. The caller must assure this.
1..MAXBITS is interpreted as that code length. zero means that that
symbol does not occur in this code.
The codes are sorted by computing a count of codes for each length,
creating from that a table of starting indices for each length in the
sorted table, and then entering the symbols in order in the sorted
table. The sorted table is work[], with that space being provided by
the caller.
The length counts are used for other purposes as well, i.e. finding
the minimum and maximum length codes, determining if there are any
codes at all, checking for a valid set of lengths, and looking ahead
at length counts to determine sub-table sizes when building the

Create and fill in decoding tables. In this loop, the table being
filled is at next and has curr index bits. The code being used is huff
with length len. That code is converted to an index by dropping drop
bits off of the bottom. For codes where len is less than drop + curr,
those top drop + curr - len bits are incremented through all values to
fill the table with replicated entries.
root is the number of index bits for the root table. When len exceeds
root, sub-tables are created pointed to by the root entry with an index
of the low root bits of huff. This is saved in low to check for when a
new sub-table should be started. drop is zero when the root table is
being filled, and drop is root when sub-tables are being filled.
When a new sub-table is needed, it is necessary to look ahead in the
code lengths to determine what size sub-table is needed. The length
counts are used for this, and so count[] is decremented as codes are
entered in the tables.
used keeps track of how many table entries have been allocated from the
provided *table space. It is checked for LENS and DIST tables against
the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
the initial root table size constants. See the comments in inftree9.h
for more information.
sym increments through all symbols, and the loop terminates when
all codes of length max, i.e. all codes, have been processed. This
routine permits incomplete codes, so another loop after this one fills
in the rest of the decoding tables with invalid code markers.

These classes provide a C++ stream interface to the zlib library. It allows you
to do things like:
gzofstream outf("blah.gz");
outf << "These go into the gzip file " << 123 << endl;
It does this by deriving a specialized stream buffer for gzipped files, which is
the way Stroustrup would have done it. :->
The gzifstream and gzofstream classes were originally written by Kevin Ruland
and made available in the zlib contrib/iostream directory. The older version still
compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of
this version.
The new classes are as standard-compliant as possible, closely following the
approach of the standard library's fstream classes. It compiles under gcc versions
3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard
library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs
from the previous one in the following respects:
- added showmanyc
- added setbuf, with support for unbuffered output via setbuf(0,0)
- a few bug fixes of stream behavior
- gzipped output file opened with default compression level instead of maximum level
- setcompressionlevel()/strategy() members replaced by single setcompression()
The code is provided "as is", with the permission to use, copy, modify, distribute
and sell it for any purpose without fee.

Possible upgrades to gzfilebuf:
- The ability to do putback (e.g. putbackfail)
- The ability to seek (zlib supports this, but could be slow/tricky)
- Simultaneous read/write access (does it make sense?)
- Support for ios_base::ate open mode
- Locale support?
- Check public interface to see which calls give problems
(due to dependence on library internals)
- Override operator<<(ostream&, gzfilebuf*) to allow direct copying
of stream buffer to stream ( i.e. os << is.rdbuf(); )

* from http://fedora.linux.duke.edu/fc1_x86_64
* which is running on an Athlon 64 3000+ / Gigabyte GA-K8VT800M system with
* 1GB ram. The 64-bit version is about 4% faster than the 32-bit version,
* when decompressing mozilla-source-1.3.tar.gz.
*
* Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
* the gcc -S output of zlib-1.2.0/inffast.c. Zlib-1.2.0 is in beta release at
* the moment. I have successfully compiled and tested this code with gcc2.96,
* gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S
* compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
* enabled. I will attempt to merge the MMX code into this version. Newer
* versions of this and inffast.S can be found at

/* Mark Adler's comments from inffast.c: */
/*
Decode literal, length, and distance codes and write out the resulting
literal and match bytes until either not enough input or output is
available, an end-of-block is encountered, or a data error is encountered.
When large enough input and output buffers are supplied to inflate(), for
example, a 16K input buffer and a 64K output buffer, more than 95% of the
inflate execution time is spent in this routine.
Entry assumptions:
state->mode == LEN
strm->avail_in >= 6
strm->avail_out >= 258
start >= strm->avail_out
state->bits < 8
On return, state->mode is one of:
LEN -- ran out of enough output space or enough available input
TYPE -- reached end of block code, inflate() to interpret next block
BAD -- error in block data
Notes:
- The maximum input bits used by a length/distance pair is 15 bits for the
length code, 5 bits for the length extra, 15 bits for the distance code,
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
Therefore if strm->avail_in >= 6, then there is enough input to avoid
checking for available input while decoding.
- The maximum bytes that a single length/distance pair can output is 258
bytes, which is the maximum length that can be coded. inflate_fast()
requires strm->avail_out >= 258 for each loop to avoid checking for
output space.

Summary
-------
This directory contains ASM implementations of the functions
longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.
gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
assembly optimized version from Jean-loup Gailly original longest_match function
inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
original function from Mark Adler
Use instructions
----------------
Assemble the .asm files using MASM and put the object files into the zlib source
directory. You can also get object files here:
http://www.winimage.com/zLibDll/zlib124_masm_obj.zip
define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
and inffasx64.obj and gvmat64.obj as object to link.
Build instructions
------------------
run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)
ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK
You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
