+---------------------------
+
+1. If not in POSIX mode, changes to ENVIRON are reflected into
+ gawk's environment, affecting any programs run by system()
+ or for piped redirections.
+
+2. The series of numbers returned by rand() should now be "more
+ random" than previously. Gawk's rand() remains repeatable; you will
+ get the same series of numbers each time you call rand() repeatedly,
+ but this will be a different series than previously.
+
+3. The --pretty-print option no longer runs the program too.
+
+4. The igawk script and igawk.1 man page are no longer installed by
+ `make install'. They have been obsolete since gawk 4.0.0.
+
+5. Gawk now has a `div()' function to perform integer division; this is
+ primarily useful for the -M option to avoid MPFR division when all
+ values involved are integers.
+
+6. Gawk can now be built with CMake. This is an alternative build
+ system for those who may want it; gawk is not going to switch off
+ use of the autotools anytime soon, if ever.

+CMake is a build automation system
+ http://en.wikipedia.org/wiki/Cmake
+
+We try to use it as a replacement for the established GNU build system.
+This attempt is currently only experimental. If you wonder why anyone
+should do this, read
+
+ Why the KDE project switched to CMake -- and how
+ http://lwn.net/Articles/188693/
+ Escape from GNU Autohell!
+ http://www.shlomifish.org/open-source/anti/autohell
+
+- How can I get GNU Awk compiled with CMake as fast as possible ?
+ git clone git://git.savannah.gnu.org/gawk.git
+ cd gawk
+ git checkout cmake
+ mkdir build
+ cd build
+ cmake ..
+ make
+ ./gawk --version
+ make test
+Notice that this git-checkout allows you to read the source code,
+track the cmake branch and get updates. You will not be able to
+commit anything.
+
+- How can I use git to contribute source code ?
+You need an account at Savannah. Read this to understand the first steps:
+ http://savannah.gnu.org/maintenance/UsingGit
+ README.git
+Use your account there to register your public ssh key at Savannah.
+Then you are ready to checkout. Remember that (when cloning) you are
+setting up your own local repository and make sure you configure it
+properly.
+ git clone ssh://my_account_name@git.sv.gnu.org/srv/git/gawk.git
+ git config --global user.name "first-name last-name"
+ git config --global user.email First.Last@email.com
+ git config --global color.ui auto
+
+- What is the current status of the cmake branch ?
+It has just begun, pre-alpha, unclear if it will ever be taken up
+by the maintainer. We want to study if using CMake with such a
+basic tool like gawk is feasible and if it easier to use than
+the GNU build system.
+
+- Where can I find a tutorial on CMake basics ?
+Use the "official tutorial":
+ http://www.cmake.org/cmake/help/cmake_tutorial.html
+
+- Where is the reference of all commands and variables ?
+Depending on the CMake version you use, select one of these:
+ http://www.cmake.org/cmake/help/v2.8.10/cmake.html
+
+- How can I cross-compile ?
+Proceed in the same way as explained above for native compilation,
+but use a different build directory. When using CMake, do this:
+ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain_mingw32.cmake ..
+Write a new Toolchain file for your cross-compiler and use it.
+
+- How can I build an installable file ?
+Use "make package". The exact kind of installable file depends on your
+operating system and defaults to TGZ.
+
+- Can I build an executable that runs on any Win32 platform ?
+Yes, there are two ways of doing this.
+In both cases you need a MinGW compiler and the NSIS package builder
+installed on the host that shall do the build.
+ http://sourceforge.net/projects/mingw
+ http://sourceforge.net/projects/nsis
+When installed properly, the NSIS tool can even build an installer file
+(a single .exe file that unpacks, registers and installs the gawk executable
+and several other files).
+1. way: native build on a Win32 platform
+ http://www.cmake.org/cmake/help/runningcmake.html
+ After clicking "Configure" select the MinGW option with the default native compiler
+ In the build directory, the command "mingw32-make" will build the gawk.exe
+ The command "mingw32-make package" will build installer file
+2. way: build with cross-compiler on a Linux platform like Ubuntu 12.04 LTS
+ Proceed as describe above for cross-compilers.
+ The command "make ; make package" will build gawk.exe and the installer file
+
+- How can I run test cases ?
+You can run all the test cases that are defined in test/Makefile.am.
+These test case scripts were not changed, but the way they are invoked has
+been adapted to CMake habits.
+See http://cmake.org/Wiki/CMake/Testing_With_CTest#Simple_Testing
+ cmake ..
+ make
+ make test # run all test cases
+ ctest -N # list all test cases but don't run them
+ ctest -R BASIC # run all test cases belonging to group BASIC
+ ctest -R MPFR # run all test cases belonging to group MPFR
+ ctest -E SHLIB.filefunc # run all tests, except the SHLIB.filefunc test case
+Remember that running test cases is possible only after a native build.

+Wed Jun 25 22:28:05 IDT 2014
+============================
+
+There were too many files tracking different thoughts and ideas for
+things to do, or consider doing. This file merges them into one. As
+tasks are completed, they should be moved to the DONE section, below,
+or simply removed.
+
+Upon creation of a release (major or patch release), items from the
+previous release should be removed.
+
+This file should exist only in the master branch or branches based off
+of it for development, but not in the stable branch. This may require some
+careful work with Git.
+
+TODO
+====
+
+Minor Cleanups and Code Improvements
+------------------------------------
+
+ Review the bash source script for working with shared libraries in
+ order to nuke the use of libtool. [ Partially started in the
+ nolibtool branch. ]
+
+ Enhance profiling to save comments in a byte-code that does nothing
+ but that can be used when pretty printing the program.
+
+ API:
+ ??? #if !defined(GAWK) && !defined(GAWK_OMIT_CONVENIENCE_MACROS)
+
+ ?? Add debugger commands to reference card
+
+ Look at function order within files.
+
+ regex.h - remove underscores in param names
+
+ Consider removing use of and/or need for the protos.h file.
+
+ Recheck if gnulib regex can be dropped in
+
+ Fully synchronize whitespace tests (for \s, \S in Unicode
+ environment) with those of GNU grep.
+
+Minor New Features
+------------------
+
+ Enhance extension/fork.c waitpid to allow the caller to specify
+ the options. And add an optional array argument to wait and
+ waitpid in which to return exit status information.
+
+ Consider relaxing the strictness of --posix.
+
+ Make it possible to put print/printf + redirections into
+ an expression.
+
+ ? Add an optional base to strtonum, allowing 2-36.
+
+ ? Optional third argument for index indicating where to start the
+ search.
+
+Major New Features
+------------------
+
+ Think about how to generalize indirect access. Manuel Collado
+ suggests things like
+
+ foo = 5
+ @"foo" += 4
+
+ Also needed:
+
+ Indirect calls of built-ins
+ Indirect calls of extension functions
+ Indirect through array elements, not just scalar variables
+
+ Some way to make regexp constants first class citizens:
+ - Assign to variables
+ - Pass to functions
+ Tawk has this and it would also make indirect calling of builtins
+ work more reasonably. Probably would use a special syntax like
+ @/.../ for such objects.
+
+ Consider a typeof() function that returns a string (scalar, array,
+ regexp).
+
+ Add ability to do decimal arithmetic.
+
+ Rework management of array index storage. (Partially DONE.)
+
+ Consider using an atom table for all string array indices.
+
+ DBM storage of awk arrays. Try to allow multiple dbm packages.
+
+ ?? A RECLEN variable for fixed-length record input. PROCINFO["RS"]
+ would be "RS" or "RECLEN" depending upon what's in use.
+ *** Could this be done as an extension?
+
+ ?? Use a new or improved dfa and/or regex library.
+
+ Rewrite in C++.
+
+Things To Think About That May Never Happen
+-------------------------------------------
+
+ Consider making shadowed variables a warning and not
+ a fatal warning when --lint=fatal.
+
+ Similar for extra parameters in a function call.
+
+ Look at code coverage tools, like S2E: https://s2e.epfl.ch/
+
+ Try running with diehard. See http://www.diehard-software.org,
+ https://github.com/emeryberger/DieHard
+
+ Implement namespaces. Arnold suggested the following in an email:
+ - Extend the definition of an 'identifier' to include "." as a valid
+ character although an identifier can't start with it.
+ - Extension libraries install functions and global variables with names
+ that have a "." in them: XML.parse(), XML.name, whatever.
+ - Awk code can read/write such variables and call such functions,
+ but they cannot define such functions
+ function XML.foo() { .. } # error
+ or create a variable with such a name if it doesn't exist. This would
+ be a run-time error, not a parse-time error.
+ - This last rule may be too restrictive.
+ I don't want to get into fancy rules a la perl and file-scope visibility
+ etc, I'd like to keep things simple. But how we design this is going
+ to be very important.
+
+ Include a sample rpm spec file in a new packaging subdirectory.
+ (Really needed?)
+
+ Patch lexer for @include and @load to make quotes optional.
+ (Really needed?)
+
+ ? Have strftime() pay attention to the value of ENVIRON["TZ"]
+
+ Add a lint check if the return value of a function is used but
+ the function did not supply a value.
+
+ Consider making gawk output +nan for NaN values so that it
+ will accept its own output as input.
+ NOTE: Investigated this. GLIBC formats NaN as '-nan'
+ and -NaN as 'nan'. Dealing with this is not simple.
+
+ Enhance FIELDWIDTHS with some way to indicate "the rest of the record".
+ E.g., a length of 0 or -1 or something. Maybe "n"?
+
+
+DONE

+
+Minor Cleanups and Code Improvements
+------------------------------------
+
+Minor New Features
+------------------
+
+Major New Features
+------------------
+
+Things That We Decided We Will Never Do
+=======================================
+
+ Consider moving var_value info into Node_var itself to reduce
+ memory usage. This would break all uses of get_lhs in the
+ code. It's too sweeping a change.
+
+ Add macros for working with flags instead of using & and |
+ directly.
+
+ FIX regular field splitting to use FPAT algorithm.
+ Note: Looked at this. Not sure it's with the trouble:
+ If it ain't broke...
+
+ Scope IDs for IPv6 addresses
+
+ Gnulib
+
+ Make FIELDWIDTHS be an array?
+
+ "Do an optimization pass over parse tree?"
+ This isn't relevant now that we are using a byte code engine.
+
+ "Consider integrating Fred Fish's DBUG library into gawk."
+ I did this once as an experiment. But I don't see a lot of value
+ to this at this stage of the development. Stepping through things
+ in a debugger is generally enough. Also, I would have to try to
+ track down the latest version of this.
+
+ "Make awk '/foo/' files... run at egrep speeds (how?)"
+ This has been on the list since the early days (gawk 1.x or early
+ 2.x). But I am not sure how to really do this, nor have I done
+ timings, nor does there seem to be any real demand for this.
+
+ Change from dlopen to using the libltdl library (i.e. lt_dlopen).
+ This may support more platforms. If we move off of libtool
+ then this is the wrong direction.

+ * Call random() twice to fill in more bits in the value
+ * of the double. Also, there is a bug in random() such
+ * that when the values of successive values are combined
+ * like (rand1*rand2)^2, (rand3*rand4)^2, ... the

+ * (4) The code is typical of many published fragments for converting
+ * from integer to floating-point, and I discuss the serious pitfalls
+ * in my book, because it leads to platform-dependent behavior at the
+ * end points of the interval [0,1]
+ *
+ * (5) the documentation in the gawk info node says
+ *
+ * `rand()'
+ * Return a random number. The values of `rand()' are uniformly
+ * distributed between zero and one. The value could be zero but is
+ * never one.(1)
+ *
+ * The division by RAND_DIVISOR may not guarantee that 1.0 is never
+ * returned: the programmer forgot the platform-dependent issue of
+ * rounding.
+ *
+ * For points 4 and 5, the safe way is a loop:
+ *

+ * rand(void) // return value in [0.0, 1.0)

+#
+# Hi Arnold,
+#
+# Attached below is a script that tests gawk for this particular
+# rand() problem. The pair-wise combinations show a strong
+# autocorrelation for a delay of 31 pairs of rand() samples.
+#
+# The script prints out the measured autocorrelation for a record
+# of NSAMPLES pairs. It also prints a fail message at the end if
+# it fails.
+#
+# If you want to see the autocorrelation values, there is a print
+# statement that if uncommented will save them to a file.
+#
+# Please let me know if the mailer screws up the transfer or
+# if you have any questions about the test.
+#
+# Best regards,
+# Bob
