Beta release of gawk 4.2.0 now available
This note is to announce the BETA release of GNU Awk 4.2.0
It is available from:
http://www.skeeve.com/gawk/gawk-4.1.65.tar.gz
This is a major release, with many significant new features.
The important part of the NEWS file is below.
As far as I can tell, the documentation and code have both hit the
freeze point.
So, why do a beta release? So that you, yes you, the end user, can see
if anything I've done breaks gawk for you. Then you can TELL ME ABOUT
IT so that I can fix it for the final release.
Thanks,
Arnold Robbins

Changes from 4.1.4 to 4.2.0
---
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. This can also affect built-in routines, such
as mktime(), which is typically influenced by the TZ environment variable.
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 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.
6. Gawk now processes a maximum of two hexadecimal digits in \x
escape sequences inside strings.
7. Setting PROCINFO["redirection", "NONFATAL"] to true makes I/O
errors for "redirection" not fatal, setting ERRNO. Setting
PROCINFO["NONFATAL"] makes all I/O nonfatal.
8. MirBSD is no longer supported.
9. Pretty printing now preserves comments and places them into the
pretty-printed file.
10. `make install' now installs shell startup files
$sysconfdir/profile.d/gawk.{csh,sh} containing shell functions to
manipulate the AWKPATH and AWKLIBPATH environment variables. On a Fedora
system, these files belong in /etc/profile.d, but the appropriate location
may be different on other platforms.
11. Gawk now supports retryable I/O via PROCINFO[input-file, "RETRY"]; see
the manual.
12. The API minor version has been increased to 2; the get_file()
API provides access to open redirections. Also see the manual.
13. Revisions in the POSIX standard remove the special case for POSIX
mode when FS = " " where newline was not a field separator. The code
and doc have been updated.
14. Gawk now supports strongly typed regexp constants. Such constants
look like @/.../. You can assign them to variables, pass them to
functions, use them in ~, !~ and the case part of a switch statement.
More details are provided in the manual.
15. The new typeof() function can be used to indicate if a variable or
array element is an array, regexp, string or number. The isarray()
function is deprecated in favor of typeof().
16. As promised when 4.1 was released, the old extension mechanism,
using the `extension' function, is now gone.
17. Support for GNU/Linux on Alpha systems has been removed.
18. Optimizations are now enabled by default. Use the new -s/--no-optimize
option(s) to disable them. Pretty-printing and profiling automatically
disable optimizations so that the output program is the same as the
original input program.
19. The extension API now provides a mechanism for generating nonfatal
error messages.
21. Gawk now uses fwrite_unlocked if it's available. The yields a 7% - 18%
improvement in raw output speed (gawk '{ print }' on a large file).
22. Pretty-printing now uses the original text of constant numeric values for
pretty-printing and profiling.
23. Passing negative operands to any of the bitwise functions now
produces a fatal error.
24. The C API has undergone changes that break binary compatibility with
the previous version. Thus the API version is now at 2.0. YOU WILL
NEED TO RECOMPILE YOUR EXTENSIONS to work with this version of gawk.
Source code compatibility remains intact, although you will get
compiler warnings if you do not revise your extensions. We strongly
recommend that you do so. Fortunately, the changes are fairly minor
and straightforward.
25. Programs that toggle IGNORECASE a lot should now be noticeably faster.
26. The mktime func

This is a major new release, with a number of new features. The relevant
part of the NEWS file is appended below.
This release represents over four years of very hard work by a number
of people. I thank them all for their contributions, I could not have
done it by myself.
Differences from gawk 4.1.4 are not available; they would be too large.
The usual GNU build incantation should be used:
tar -xpvzf gawk-4.2.0.tar.gz

pretty-printed file.
* Pretty-printing now uses the original text of constant numeric values
for pretty-printing and profiling.

were in the source file. This solves several niggling corner cases
with such things.

Changes from 4.2.1 to 5.0.0
---
1. Support for the POSIX standard %a and %A printf formats has been added.
2. The test infrastructure has been greatly improved, simplifying the
contents of test/Makefile.am and making it possible to generate
pc/Makefile.tst from test/Makefile.in.
3. The regex routines have been replaced with those from GNULIB, allowing
me to stop carrying forward decades of changes against the original
ones from GLIBC.
4. Infrastructure upgrades: Bison 3.3, Automake 1.16.1, Gettext 0.19.8.1,
makeinfo 6.5.
5. The undocumented configure option and code that enabled the use of
non-English "letters" in identifiers is now gone.
6. The `--with-whiny-user-strftime' configuration option is now gone.
7. The code now makes some stronger assumptions about a C99 environment.
8. PROCINFO["platform"] yields a string indicating the platform for
which gawk was compiled.
9. Writing to elements of SYMTAB that are not variable names now
causes a fatal error. THIS CHANGES BEHAVIOR.
10. Comment handling in the pretty-printer has been reworked almost completely
from scratch. As a result, comments in many corner cases that were
previously lost are now included in the formatted output.
11. Namespaces have been implemented! See the manual. One consequence of this
is that files included with -i, read with -f, and command line program
segments must all be self-contained syntactic units. E.g., you can no
longer do something like this:
gawk -e 'BEGIN {' -e 'print "hello" }'
12. Gawk now uses the locale settings for ignoring case in single byte
locales, instead of hardwiring in Latin-1.
13. A number of bugs, some of them quite significant, have been fixed.
See the ChangeLog for details.

The relevant part of the NEWS file is appended below. This release represents a lot of very hard work by a number of people. I thank them all for their contributions, I could not have done it by myself. Differences from gawk 5.1.1 are not available; they would be too large. The online documentation on the GNU web site is already updated, including a manual for the new persistent memory feature.

If it doesn't work for you, then send email to bug-g...@gnu.org. NOTE that the manual's instructions for sending bug reports have been updated. Please review them carefully before submitting a report! ONLY bug reports should be submitted to the bug-gawk list. All other questions should use the relatively new help-g...@gnu.org mailing list.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. Changes from 5.1.x to 5.2.0 --- * * MPFR mode (the -M option) is now ON PAROLE. This feature is now being* * supported by a volunteer in the development team and not by the primary * * maintainer. If this situation changes, then the feature will be removed. * * For more information see this section in the manual: * * https://www.gnu.org/software/gawk/manual/html_node/MPFR-On-Parole.html* * 1. Infrastructure upgrades: Libtool 2.4.7, Bison 3.8.2. 2. Numeric scalars now compare in the same way as C for the relational operators. Comparison order for sorting has not changed. This only makes a difference when comparing Infinity and NaN values with regular numbers; it should not be noticeable most of the time. 3. If the AWK_HASH environment variable is set to "fnv1a" gawk will use the FNV1-A hash function for associative arrays. 4. The CMake infrastructure has been removed. In the five years it was in the tree, nobody used it, and it was not updated. 5. There is now a new function, mkbool(), that creates Boolean-typed values. These values *are* numbers, but they are also tagged as Boolean. This is mainly for use with data exchange to/from languages or environments that support real Boolean values. See the manual for details. 6. As BWK awk has supported interval expressions since 2019, they are now enabled even if --traditional is supplied. The -r/--re-interval option remains, but it does nothing. 7. The rwarray extension has two new functions, writeall() and readall(), for saving / restoring all of gawk's variables and arrays. 8. The new `gawkbug' script should be used for reporting bugs. 9. The manual page (doc/gawk.1) has been considerably reduced in size. Wherever possible, details were replaced with references to the online copy of the manual. 10. Gawk now supports Terence Kelly's "persistent malloc" (pma), allowing gawk to preserve its variables, arrays and user-defined functions between runs. THIS IS AN EXPERIMENTAL FEATURE! For more information, see the manual. A new pm-gawk.1 man page is included, as is a separate user manual that focuses on the feature. 11. Support for OS/2 has been removed. It was not being actively maintained. 12. Similarly, support for DJGPP has been removed. It also was not being actively maintained. 13. VAX/VMS is no longer supported, as it can no longer be tested. The files for it remain in the distribution but will be removed eventually. 14. Some subtle issues with untyped array elements being passed to functions have been fixed. 15. Syntax errors are now immediately fatal. This prevents problems with errors from fuzzers and other such things. 16. There have been numerous minor code cleanups and bug fixes. See the ChangeLog for details. Changes from 5.1.1 to 5.1.x --- 1. Infrastructure upgrades: Automake 1.16.5, Texinfo 6.8. 2. The rwarray extension now supports writ
