Changes from 3.1.7 to 3.1.8
|
|
---------------------------
|
|
1. The zero flag no longer applies to %c and %s; apparently the standards
|
|
changed at some point.
|
|
|
|
2. Updated to latest infrastructure: Autoconf 2.65, Automake 1.11.1,
|
|
libtool 2.2.6b, Bison 2.4.2.
|
|
|
|
3. Failure to open a socket is no longer a fatal error.
|
|
|
|
4. dfa.h and dfa.c are now more-or-less in sync with GNU grep, for the first
|
|
time in many years.
|
|
|
|
5. Gawk no longer includes its own copy of libsigsegv but it will use it if
|
|
installed on the build system. The --disable-libsigsegv configure option
|
|
is now gone.
|
|
|
|
6. The ' flag (%'d) is now just ignored on systems that can't support it.
|
|
|
|
7. Lots of bug fixes, see the ChangeLog.
|
|
|
|
Changes from 3.1.6 to 3.1.7
|
|
---------------------------
|
|
1. Gawk now has support for z/OS (IBM S/390 architecture).
|
|
|
|
2. Gawk now handles multibyte strings better in [s]printf with field
|
|
widths and such.
|
|
|
|
3. Gawk now uses libsigsegv to print a message before core dumping. This
|
|
handles infinite recursion of an awk function a little better.
|
|
Use of the library can be disabled at configure time with the
|
|
--disable-libsigsegv option for unusual systems.
|
|
|
|
4. The handling of BINMODE is now somewhat more sane.
|
|
|
|
5. A getline from a directory is no longer fatal; instead it returns -1.
|
|
|
|
6. Per POSIX, special variable names (like FS) cannot be used as function
|
|
parameter names.
|
|
|
|
7. The new -O / --optimize option enables simple constant folding on
|
|
the parse tree during parsing. We hope that with time the number
|
|
of optimizations will increase.
|
|
|
|
8. Updated to the latest autotools: Autoconf 2.63, Automake 1.11,
|
|
Libtool 2.2.6a, and Gettext 0.17. Also latest Bison: 2.4.1.
|
|
|
|
9. Some improvement in testing for isinf / isnan in builtin.c.
|
|
|
|
10. Improved the handling of `a = a b c' to be more general.
|
|
|
|
11. Locale handling for %'d should now work on certain non-Unix /
|
|
non-Linux systems.
|
|
|
|
12. Lots of bugs fixed, see the ChangeLog for the details.
|
|
|
|
Changes from 3.1.5 to 3.1.6
|
|
---------------------------
|
|
|
|
1. `gawk 'program' /non/existant/file' no longer core dumps.
|
|
|
|
2. Too many people the world over have complained about gawk's use of the
|
|
locale's decimal point for parsing input data instead of the traditional
|
|
period. So, even though gawk was being nicely standards-compliant, in
|
|
a Triumph For The Users, gawk now only uses the locale's decimal point
|
|
if --posix is supplied or if POSIXLY_CORRECT is set. It is the sincere
|
|
hope that this change will eliminate this FAQ from being asked.
|
|
|
|
3. `gawk -v BINMODE=1 ...' works again.
|
|
|
|
4. Internal file names like `/dev/user' now work again. (Note that these
|
|
file names are obsolete and will go away eventually.)
|
|
|
|
5. Problems with wide strings in non "C" locales have been straightened
|
|
out everywhere. (At least, we think so.)
|
|
|
|
6. Use of `ansi2knr' is no longer supported. Please use an ANSI C compiler.
|
|
|
|
7. Updated to Autoconf 2.61, Automake 1.10, and Gettext 0.16.1.
|
|
|
|
8. The getopt* and regex* files were synchronized with current GLIBC CVS.
|
|
See the ChangeLog for the versions and minor edits made.
|
|
|
|
9. There are additional --lint-old warnings.
|
|
|
|
10. Gawk now uses getaddrinfo(3) to look up names and IP addresses. This
|
|
allows the use of an IPv6 format address and paves the way for
|
|
eventual addition of `/inet6/...' and `/inet4/...' hostnames.
|
|
|
|
11. We believe gawk to now be valgrind clean. At least when run against
|
|
the test suite.
|
|
|
|
12. A number of issues dealing with the formatting and printing of very
|
|
large numbers in integer formats have been dealt with and fixed.
|
|
|
|
13. Gawk now converts "+inf", "-inf", "+nan" and "-nan" into the corresponding
|
|
magic IEEE floating point values. Only those strings (case independent)
|
|
work. With --posix, gawk calls the system strtod directly. You asked
|
|
for it, you got it, you deal with it.
|
|
|
|
14. Defining YYDEBUG enables the -D command line option.
|
|
|
|
15. Gawk should now work out of the box on Tandem NSK/OSS systems.
|
|
|
|
16. Lint messages rationalized: many more of the messages are now printed
|
|
only once, instead of every time they are encountered.
|
|
|
|
17. The strftime() function now accepts an optional third argument, which
|
|
if non-zero or non-null, indicates that the time should be formatted
|
|
as UTC instead of as local time.
|
|
|
|
18. The precedence of concatenation and `| getline' (in something like
|
|
"echo " "date" | getline stuff) has been reverted to the earlier
|
|
behavior and now once again matches Unix awk.
|
|
|
|
19. New configure time flag --disable-directories-fatal which causes
|
|
gawk to silently skip directories on the command line. This behavior
|
|
is also enabled for --traditional, since it's what Unix awk does.
|
|
|
|
20. A new option, --use-lc-numeric, forces use of the locale's decimal
|
|
point without the rest of the draconian restrictions imposed by
|
|
--posix. This softens somewhat the stance taken in item #2.
|
|
|
|
21. Everything relevant has been updated to the GPL 3.
|
|
|
|
22. Array growth should be faster now, at no cost in space.
|
|
|
|
23. Lots more tests.
|
|
|
|
24. One new translation.
|
|
|
|
25. Various bugs fixed, see the ChangeLog for details.
|
|
|
|
Changes from 3.1.4 to 3.1.5
|
|
---------------------------
|
|
|
|
1. The random() suite has been updated to a current FreeBSD version, which
|
|
works on systems with > 32-bit ints.
|
|
|
|
2. A new option, `--exec' has been added. It's like -f but ends option
|
|
processing. It also disables `x=y' variable assignments, but not -v.
|
|
It's needed mainly for CGI scripts, so that source code can't be
|
|
passed in as part of the URL.
|
|
|
|
3. dfa.[ch] have been synced with GNU grep development. This also fixes
|
|
multiple regex matching problems in multibyte locales.
|
|
|
|
4. Updated to Automake 1.9.5.
|
|
|
|
5. Updated to Bison 2.0.
|
|
|
|
6. The getopt* and regex* files were synchronized with current GLIBC CVS.
|
|
See the ChangeLog for the versions and minor edits made.
|
|
|
|
7. `configure --disable-nls' now disables just gawk's own translations.
|
|
Gawk continues to work with the locale's numeric formatting. This
|
|
includes a bug fix in handling the printf ' flag (e.g., %'d).
|
|
|
|
8. Gawk is now multibyte aware. This means that index(), length(),
|
|
substr() and match() all work in terms of characters, not bytes.
|
|
|
|
9. Gawk is now smarter about parsing numeric constants in corner cases.
|
|
|
|
11. Not closing open redirections no longer causes gawk to exit non-zero.
|
|
|
|
10. The VMS port has been updated.
|
|
|
|
11. Changes from Andrew Schorr at the xmlgawk project to provide for
|
|
open hooks from extensions are now included. This will let the
|
|
xmlgawk extension work in the standard gawk.
|
|
|
|
12. Updated to gettext 0.14.4. Gawk no longer includes its own copy
|
|
of the gettext `intl' library, following current GNU practice to
|
|
rely on there being an external version thereof.
|
|
|
|
13. A regexp of the form `//' will now generate a warning that it
|
|
is not a C++ comment from --lint (awk.y).
|
|
|
|
14. The ^ and ^= operators with an integer exponent now use Exponentiation
|
|
by Squaring. This simultaneously fixes a problem with ^= and a negative
|
|
integer exponent.
|
|
|
|
15. length(array) now returns the number of elements in the array. This is
|
|
is a non-standard extension that will fail in POSIX mode.
|
|
|
|
16. Carriage return characters are now ignored in program source code.
|
|
|
|
17. Four new translations added.
|
|
|
|
18. Various minor bugs fixed. See the ChangeLog for the details.
|
|
|
|
Changes from 3.1.3 to 3.1.4
|
|
---------------------------
|
|
|
|
1. Gawk now supports the POSIX %F format, falling back to %f if the local
|
|
system printf doesn't handle it.
|
|
|
|
2. Gawk now supports the ' flag in printf. E.g., %'d in a locale with thousands
|
|
separators includes the thousands separator in the value, e.g. 12,345.
|
|
|
|
This has one problem; the ' flag is next to impossible to use on the
|
|
command line, without major quoting games. Oh well, TANSTAAFL.
|
|
|
|
3. The dfa code has been reinstated; the performance degradation was
|
|
just too awful. Sigh. (For fun, use `export GAWK_NO_DFA=1' to
|
|
see the difference.)
|
|
|
|
4. The special case `x = x y' is now recognized in the grammar, and gawk
|
|
now uses `realloc' to append the new value to the end of the existing
|
|
one. This can speed up the common case of appending onto a string.
|
|
|
|
5. The dfa code was upgraded with most of the fixes from grep 2.5.1, and
|
|
the regex code was upgraded with GLIBC as mid-January 2004. The regex
|
|
code is faster than it was, but still not as fast as the dfa code, so
|
|
the dfa code stays in. The getopt code was also synced to current GLIBC.
|
|
|
|
6. Support code upgraded to Automake 1.8.5, Autoconf 2.59, and gettext 0.14.1.
|
|
|
|
7. When --posix is in effect, sub/gsub now follow the 2001 POSIX behavior.
|
|
Yippee. This is even documented in the manual.
|
|
|
|
8. Gawk will now recover children that have died (input pipelines, two-way
|
|
pipes), upon detecting EOF from them, thus avoiding filling
|
|
up the process table. Open file descriptors are not recovered
|
|
(unfortunately), since that could break awk semantics. See the
|
|
ChangeLog and the source code for the details.
|
|
|
|
9. Handling of numbers like `0,1' in non-American locales ought to
|
|
work correctly now.
|
|
|
|
10. IGNORECASE is now locale-aware for characters with values above 128.
|
|
The dfa matcher is now used for IGNORECASE matches too.
|
|
|
|
11. Dynamic function loading is better. The documentation has been improved
|
|
and some new APIs for use by dynamic functions have been added.
|
|
|
|
12. Gawk now has a fighting chance of working on older systems,
|
|
a la SunOS 4.1.x.
|
|
|
|
13. Issues with multibyte support on HP-UX are now resolved. `configure' now
|
|
disables such support there, since it's not up to what gawk needs.
|
|
|
|
14. There are now even more tests in the test suite.
|
|
|
|
15. Various bugs fixed; see ChangeLog for the details.
|
|
|
|
Changes from 3.1.2 to 3.1.3
|
|
---------------------------
|
|
|
|
1. Gawk now follows POSIX in handling of local numeric formats for
|
|
input, output and number/string conversions.
|
|
|
|
2. Multibyte detection improved. See README_d/README.multibyte for more
|
|
info about multibyte locales.
|
|
|
|
3. Handling of `close' made more POSIX-compliant for POSIXLY_CORRECT,
|
|
see the documentation.
|
|
|
|
4. The record reading code was redone, again. This time it's much
|
|
better. Really!
|
|
|
|
5. For RS = "\n" and RS = "", gawk now only sets RT when it has changed.
|
|
This provides considerable performance improvement.
|
|
|
|
6. `match' now sets all the subscripts in the third argument array
|
|
correctly, even if not all subexpressions matched.
|
|
|
|
7. Updated to Automake 1.7.5. configure.in renamed configure.ac.
|
|
|
|
8. C-style switch statements are available, but must be enabled at
|
|
compile time via `configure --enable-switch'. For 3.2 they'll be
|
|
enabled by default. Thanks to Michael Benzinger for the initial
|
|
code.
|
|
|
|
9. %c now always prints no more than one character, whatever
|
|
precision is provided.
|
|
|
|
10. strtonum(<number>) now works again.
|
|
|
|
11. Gawk is now much better about scalar/array typing of global
|
|
uninitiailzed variables passed as parameters. Once the parameter
|
|
is then used one way or the other, the global var's type is
|
|
adjusted accordingly. Thanks to Stepan Kasal for the original
|
|
(considerable) changes.
|
|
|
|
12. Dynamic function loading under Windows32 should now be possible. See
|
|
README_d/README.pcdynamic. Thanks to Patrick T.J. McPhee for the changes.
|
|
|
|
13. Updated to gettext 0.12.1.
|
|
|
|
14. Gawk now follows historical practice and POSIX for the return
|
|
value of `rand': It's now 0 <= N < 1.
|
|
|
|
Changes from 3.1.1 to 3.1.2
|
|
---------------------------
|
|
|
|
1. Loops of the form:
|
|
|
|
for (iggy in foo)
|
|
next
|
|
|
|
no longer leak memory.
|
|
|
|
2. gawk -v FIELDWIDTHS="..." now sets PROCINFO["FS"] correctly.
|
|
|
|
3. All builtin operations and functions should now fully evaluate their
|
|
arguments so that side effects take place correctly.
|
|
|
|
4. Fixed a logic bug in gsub/gensub for matches to null strings that occurred
|
|
later in the string after a nonnull match.
|
|
|
|
5. getgroups code now works on Ultrix again.
|
|
|
|
6. Completely new version of the full GNU regex engine now in place.
|
|
|
|
7. Argument parsing and variable assignment has been cleaned up.
|
|
|
|
8. An I/O bug on HP-UX has been documented and worked around. See
|
|
README_d/README.hpux.
|
|
|
|
9. awklib/grcat should now compile correctly.
|
|
|
|
10. Updated to automake 1.7.3, autoconf 2.57 and gettext 0.11.5 ; thanks to
|
|
Paul Eggert for the initial automake and autoconf work.
|
|
|
|
11. As a result of #6, removed the use of the dfa code from GNU grep.
|
|
|
|
12. It is now possible to use ptys for |& two-way pipes instead of
|
|
pipes. The basic plumbing for this was provided by Paolo Bonzini.
|
|
To make this happen:
|
|
|
|
command = "unix command etc"
|
|
PROCINFO[command, "pty"] = 1
|
|
|
|
print ... |& command
|
|
command |& getline stuff
|
|
|
|
In other words, set the element in PROCINFO *before* opening the
|
|
two-way pipe, and then gawk will use ptys instead of pipes.
|
|
|
|
On systems without ptys or where all the ptys are in use, gawk
|
|
will fall back to using plain pipes.
|
|
|
|
13. Fixed a regex matching across buffer boundaries bug, with a
|
|
heuristic. See io.c:rsre_get_a_record.
|
|
|
|
14. Profiling no longer dumps core if there are extension functions in place.
|
|
|
|
15. Grammar and scanner cleaned up, courtesy of Stepen Kasal, to hopefully
|
|
once and for all fix the `/=' operator vs. `/=.../' regex ambiguity.
|
|
Lots of other grammar simplifications applied, as well.
|
|
|
|
16. BINMODE should work now on more Windows ports.
|
|
|
|
17. Updated to bison 1.875. Includes fix to bisonfix.sed script.
|
|
|
|
18. The NODE structure is now 20% (8 bytes) smaller (on x86, anyway), which
|
|
should help conserve memory.
|
|
|
|
19. Builds not in the source directory should work again.
|
|
|
|
20. Arrays now use 2 NODE's per element instead of three. Combined with
|
|
#18, (on the x86) this reduces the overhead from 120 bytes per element
|
|
to just 64 bytes: almost a 50% improvement.
|
|
|
|
21. Programs that make heavy use of changing IGNORECASE should now be
|
|
much faster, particularly if using a regular expression for FS or RS.
|
|
IGNORECASE now correctly affects RS regex record splitting, as well.
|
|
|
|
22. IGNORECASE no longer affects single-character field splitting (FS = "c"),
|
|
or single-character record splitting (RS = "c").
|
|
|
|
This cleans up some weird behavior, and makes gawk better match the
|
|
documentation, which says it only affects regex-based field splitting
|
|
and record splitting.
|
|
|
|
The documentation on this was improved, too.
|
|
|
|
23. The framework in test/ has been simplified, making it much easier to
|
|
add new tests while keeping the size of Makefile.am reasonable. Thanks
|
|
for this to Stepan Kasal.
|
|
|
|
24. --lint=invalid causes lint warnings only about stuff that's actually
|
|
invalid. This needs additional work.
|
|
|
|
25. More translations.
|
|
|
|
26. The `get_a_record' routine has been revamped (currently by splitting it
|
|
into three variants). This should improve long-term maintainability.
|
|
|
|
27. `match' now adds more entries to 3rd array arg:
|
|
match("the big dog", /([a-z]+) ([a-z]+) ([a-z]+)/, data)
|
|
fills in variables:
|
|
data[1, "start"], data[1, "length"], and so on.
|
|
|
|
28. New `asorti' function with same interface as `asort', but sorts indices
|
|
instead of values.
|
|
|
|
29. Documentation updated to FDL 1.2.
|
|
|
|
30. New `configure' option --disable-lint at compile time disables lint
|
|
checking. With GCC dead-code-elimination, cuts almost 200K off the
|
|
executable size on GNU/Linux x86. Presumably speeds up runtime.
|
|
|
|
Using this will cause some of the tests in the test suite to fail.
|
|
This option may be removed at a later date.
|
|
|
|
31. Various minor cleanups, see the ChangeLog for details.
|
|
|
|
Changes from 3.1.0 to 3.1.1
|
|
---------------------------
|
|
|
|
1. Six new translations.
|
|
|
|
2. Having more than 4 different values for OFMT and/or CONVFMT now works.
|
|
|
|
3. The handling of dynamic regexes is now more more sane, esp. w.r.t.
|
|
the profiling code. The profiling code has been fixed in several
|
|
places.
|
|
|
|
4. The return value of index("", "") is now 1.
|
|
|
|
5. Gawk should no longer close fd 0 in child processes.
|
|
|
|
6. Fixed test for strtod semantics and regenerated configure.
|
|
|
|
7. Gawk can now be built with byacc; an accidental bison dependency was
|
|
removed.
|
|
|
|
8. `yyerror' will no longer dump core on long source lines.
|
|
|
|
9. Gawk now correctly queries getgroups(2) to figure out how many groups
|
|
the process has.
|
|
|
|
10. New configure option to force use of included strftime, e.g. on
|
|
Solaris systems. See `./configure --help' for the details. Replaced
|
|
the included strftime.c with the one from textutils.
|
|
|
|
11. OS/2 port has been updated.
|
|
|
|
12. Multi-byte character support has been added, courtesy of IBM Japan.
|
|
|
|
13. The `for (iggy in foo) delete foo[iggy]' -> `delete foo' optimisation
|
|
now works.
|
|
|
|
14. Upgraded to gettext 0.11.2 and automake 1.5.
|
|
|
|
15. Full gettext compatibility (new dcngettext function).
|
|
|
|
16. The O'Reilly copyedits and indexing changes for the documentation have
|
|
been folded into the texinfo version of the manuals.
|
|
|
|
17. A humongously long value for the AWKPATH environment variable will no
|
|
longer dump core.
|
|
|
|
18. Configuration / Installation issues have been straightened out in
|
|
Makefile.am.
|
|
|
|
Changes from 3.0.6 to 3.1.0
|
|
---------------------------
|
|
|
|
1. A new PROCINFO array provides info about the process. The non-I/O /dev/xxx
|
|
files are now obsolete, and their use always generates a warning.
|
|
|
|
2. A new `mktime' builtin function was added for creating time stamps. The
|
|
`mktime' function written in awk was removed from the user's guide.
|
|
|
|
3. New `--gen-po' option creates GNU gettext .po files for strings marked
|
|
with a leading underscore.
|
|
|
|
4. Gawk now completely interprets special file names internally, ignoring the
|
|
existence of real /dev/stdin, /dev/stdout files, etc.
|
|
|
|
5. The mmap code was removed. It was a worthwhile experiment that just
|
|
didn't work out.
|
|
|
|
6. The BINMODE variable is new; on non-UNIX systems it affects how gawk
|
|
opens files for text vs. binary.
|
|
|
|
7. The atari port is now unsupported.
|
|
|
|
8. Gawk no longer supports `next file' as two words.
|
|
|
|
9. On systems that support it, gawk now sets the `close on exec' flag on all
|
|
files and pipes it opens. This makes sure that child processes run via
|
|
`system' or pipes have plenty of file descriptors available.
|
|
|
|
10. New ports: Tandem and BeOS. The Tandem port is unsupported.
|
|
|
|
11. If `--posix' is in effect, newlines are not allowed after ?:.
|
|
|
|
12. Weird OFMT/CONVFMT formats no longer cause fatal errors.
|
|
|
|
13. Diagnostics about array parameters now include the parameter's name,
|
|
not just its number.
|
|
|
|
14. configure should now automatically add -D_SYSV3 for ISC Unix.
|
|
(This seems to have made it into the gawk 3.0.x line long ago.)
|
|
|
|
15. It is now possible to open a two-way pipe via the `|&' operator.
|
|
See the discussion in the manual about putting `sort' into such a pipeline,
|
|
though. (NOTE! This is borrowed from ksh: it is not the same as
|
|
the same operator in csh!)
|
|
|
|
16. The `close' function now takes an optional second string argument
|
|
that allows closing one or the other end of the two-way pipe to
|
|
a co-process. This is needed to use `sort' in a co-process, see
|
|
the doc.
|
|
|
|
17. If TCP/IP is available, special file names beginning with `/inet'
|
|
can be used with `|&' for IPC. Thanks to Juergen Kahrs for the initial
|
|
code.
|
|
|
|
18. With `--enable-portals' on the configure command line, gawk will also
|
|
treat file names that start with `/p/' as a 4.4 BSD type portal file,
|
|
i.e., a two-way pipe for `|&'.
|
|
|
|
19. Unrecognized escapes, such as "\q" now always generate a warning.
|
|
|
|
20. The LINT variable is new; it provides dynamic control over the --lint
|
|
option.
|
|
|
|
21. Lint warnings can be made fatal by using --lint=fatal or `LINT = "fatal"'.
|
|
Use this if you're really serious about portable code.
|
|
|
|
22. Due to an enhanced sed script, there is no longer any need to worry
|
|
about finding or using alloca. alloca.c is thus now gone.
|
|
|
|
23. A number of lint warnings have been added. Most notably, gawk will
|
|
detect if a variable is used before assigned to. Warnings for
|
|
when a string that isn't a number gets converted to a number are
|
|
in the code but disabled; they seem to be too picky in practice.
|
|
|
|
Also, gawk will now warn about function parameter names that shadow
|
|
global variable names.
|
|
|
|
24. It is now possible to dynamically add builtin functions on systems
|
|
that support dlopen. This facility is not (yet) as portable or well
|
|
integrated as it might be. *** WARNING *** THIS FEATURE WILL EVOLVE!
|
|
|
|
25. There are *many* new tests in the test suite.
|
|
|
|
26. Profiling has been added! A separate version of gawk, named pgawk, is
|
|
built and generates a run-time execution profile. The --profile option
|
|
can be used to change the default output file. In regular gawk, this
|
|
option pretty-prints the parse tree.
|
|
|
|
27. Gawk has been internationalized, using GNU gettext. Translations for
|
|
future distributions are most welcome. Simultaneously, gawk was switched
|
|
over to using automake. You need Automake 1.4a (from the CVS archive)
|
|
if you want to muck with the Makefile.am files.
|
|
|
|
28. New `asort' function for sorting arrays. See the doc for details.
|
|
|
|
29. The match function takes an optional array third argument to hold
|
|
the text matched by parenthesized sub-expressions.
|
|
|
|
30. The bit op functions and octal and hex source code constants are on by
|
|
default, no longer a configure-time option. Recognition of non-decimal
|
|
data is now enabled at runtime with --non-decimal-data command line option.
|
|
|
|
31. Internationalization features available at the awk level: new TEXTDOMAIN
|
|
variable and `bindtextdomain' and `dcgettext' functions. printf formats
|
|
may contain the "%2$3.5d" kind of notation for use in translations. See
|
|
the texinfo manual for details.
|
|
|
|
32. The return value from `close' has been rationalized. Most notably,
|
|
closing something that wasn't open returns -1 but remains non-fatal.
|
|
|
|
33. The array effeciency change from 3.0.5 was reverted; the semantics were
|
|
not right. Additionally, index values of previously stored elements
|
|
can no longer change dynamically.
|
|
|
|
34. The new option --dump-variables dumps a list of all global variables and
|
|
their final types and values to a file you give, or to `awkvars.out'.
|
|
|
|
35. Gawk now uses a recent version of random.c courtesy of the FreeBSD
|
|
project.
|
|
|
|
36. The gawk source code now uses ANSI C function definitions (new style),
|
|
with ansi2knr to translate code for old compilers.
|
|
|
|
37. `for (iggy in foo)' loops should be more robust now in the face of
|
|
adding/deleting elements in the middle; they loop over just the elements
|
|
that are present in the array when the loop starts.
|
|
|
|
Changes from 3.0.5 to 3.0.6
|
|
---------------------------
|
|
|
|
This is a bug fix release only, pending further development on 3.1.0.
|
|
|
|
Bugs fixed and changes made:
|
|
|
|
1. Subscripting an array with a variable that is just a number no
|
|
longer magically converts the variable into a string.
|
|
|
|
2. Similarly, running a `for (iggy in foo)' loop where `foo' is a
|
|
function parameter now works correctly.
|
|
|
|
3. Similarly, `i = ""; v[i] = a; if (i in v) ...' now works again.
|
|
|
|
4. Gawk now special cases `for (iggy in foo) delete foo[iggy]' and
|
|
treats it as the moral equivalent of `delete foo'. This should be
|
|
a major efficiency win when portably deleting large arrays.
|
|
|
|
5. VMS port brought up to date.
|
|
|
|
Changes from 3.0.4 to 3.0.5
|
|
---------------------------
|
|
|
|
This is a bug fix release only, pending further development on 3.1.0.
|
|
|
|
Bugs Fixed:
|
|
|
|
1. `function foo(foo)' is now a fatal error.
|
|
|
|
2. Array indexing is now much more efficient: where possible, only one
|
|
copy of an index string is kept, even if used in multiple arrays.
|
|
|
|
3. Support was added for MacOS X and an `install-strip' target.
|
|
|
|
4. [s]printf formatting for `0' flag and floating point formats now
|
|
works correctly.
|
|
|
|
5. HP-UX large file support with GCC 2.95.1 now works.
|
|
|
|
6. Arguments that contain `=' but that aren't syntactically valid are
|
|
now treated as filenames, instead of as fatal errors.
|
|
|
|
7. `-v NF=foo' now works.
|
|
|
|
8. Non-ascii alphanumeric characters are now treated as such in the
|
|
right locales by regex.c. Similarly, a Latin-1 y-umlaut (decimal
|
|
value 255) in the program text no longer acts like EOF.
|
|
|
|
9. Array indexes are always compared as strings; fixes an obscure bug
|
|
when user input gets used for the `x in array' test.
|
|
|
|
10. The usage message now points users to the documentation for how
|
|
to report bugs.
|
|
|
|
11. `/=' now works after an array.
|
|
|
|
12. `b += b += 1' now works correctly.
|
|
|
|
13. IGNORECASE changing with calls `match' now works better. (Fix for
|
|
semi-obscure bug.)
|
|
|
|
14. Multicharacter values for RS now generate a lint warning.
|
|
|
|
15. The gawk open file caching is now much more efficient.
|
|
|
|
16. Global arrays passed to functions are now managed better. In particular,
|
|
test/arynocls.awk won't crash referencing freed memory.
|
|
|
|
17. In obscure cases, `getline var' can no longer clobber $0.
|
|
|
|
Changes from 3.0.3 to 3.0.4
|
|
---------------------------
|
|
|
|
This is a bug fix release only, pending further development on 3.1.0.
|
|
|
|
Bugs Fixed:
|
|
|
|
1. A memory leak when turning a function parameter into an array was
|
|
fixed.
|
|
|
|
2. The non-decimal data option now works correctly.
|
|
|
|
3. Using an empty pair of brackets as an array subscript no longer causes
|
|
a core dump during parsing. In general, syntax errors should not
|
|
cause core dumps any more.
|
|
|
|
4. Standard input is no longer closed if it provides program source,
|
|
avoiding strange I/O problems.
|
|
|
|
5. Memory corruption during printing with `print' has been fixed.
|
|
|
|
6. The gsub function now correctly counts the number of matches.
|
|
|
|
7. A typo in doc/Makefile.in has been fixed, making installation work.
|
|
|
|
8. Calling `next' or `nextfile' from a BEGIN or END rule is now fatal.
|
|
|
|
9. Subtle problems in rebuilding $0 when fields were changed have been
|
|
fixed.
|
|
|
|
10. `FS = FS' now correctly turns off the use of FIELDWIDTHS.
|
|
|
|
11. Gawk now parses fields correctly when FS is a single character.
|
|
|
|
12. It is now possible for RS to be the NUL character ("\0").
|
|
|
|
13. Weird problems with number conversions on MIPS and other systems
|
|
have been fixed.
|
|
|
|
14. When parsing using FIELDWIDTHS is in effect, `split' with no third
|
|
argument will still use the value of FS.
|
|
|
|
15. Large File Support for Solaris, HP-UX, AIX, and IRIX is now enabled at
|
|
compile time, thanks to Paul Eggert.
|
|
|
|
16. Attempting to use the name of a function as a variable or array
|
|
from within the function is now caught as a fatal error, instead
|
|
of as a core dump.
|
|
|
|
17. A bug in parsing hex escapes was fixed.
|
|
|
|
18. A weird bug with concatenation where one expression has side effects
|
|
that changes another was fixed.
|
|
|
|
19. printf/sprintf now behave much better for uses of the '0' and '#' flags
|
|
and with precisions and field widths.
|
|
|
|
20. Further strangenesses with concatenation and multiple accesses of some
|
|
of the special variables was fixed.
|
|
|
|
21. The Atari port is marked as no longer supported.
|
|
|
|
22. Build problems on HP-UX have been fixed.
|
|
|
|
23. Minor fixes and additional explanations added to the documentation.
|
|
|
|
24. For RS = "", even a single leading newline is now correctly stripped.
|
|
|
|
25. Obscure parsing problems for regex constants like /=.../ fixed, so
|
|
that a regex constant is recognized, and not the /= operator.
|
|
|
|
26. Fixed a bug when closing a redirection that matched the current
|
|
or last FILENAME.
|
|
|
|
27. Build problems on AIX fixed.
|
|
|
|
Changes from 3.0.2 to 3.0.3
|
|
---------------------------
|
|
|
|
The horrendous per-record memory leak introduced in 3.0.1 is gone, finally.
|
|
|
|
The `amiga' directory is now gone; Amiga support is now entirely handled
|
|
by the POSIX support.
|
|
|
|
Windows32 support has been added in the `pc' directory. See `README_d/README.pc'
|
|
for more info.
|
|
|
|
The mmap changes are disabled in io.c, and will be removed entirely
|
|
in the next big release. They were an interesting experiment that just
|
|
really didn't work in practice.
|
|
|
|
A minor memory leak that occurred when using `next' from within a
|
|
function has also been fixed.
|
|
|
|
Problems with I/O from sub-processes via a pipe are now gone.
|
|
|
|
Using "/dev/pid" and the other special /dev files no longer causes a core dump.
|
|
|
|
The files regex.h, regex.c, getopt.h, getopt.c, and getopt1.c have been
|
|
merged with the versions in GNU libc. Thanks to Ulrich Drepper for his help.
|
|
|
|
Some new undocumented features have been added. Use the source, Luke!
|
|
It is not clear yet whether these will ever be fully supported.
|
|
|
|
Array performance should be much better for very very large arrays. "Virtual
|
|
memory required, real memory helpful."
|
|
|
|
builtin.c:do_substr rationalized, again.
|
|
|
|
The --re-interval option now works as advertised.
|
|
|
|
The license text on some of the missing/* files is now generic.
|
|
|
|
Lots more new test cases.
|
|
|
|
Lots of other small bugs fixed, see the ChangeLog files for details.
|
|
|
|
Changes from 3.0.1 to 3.0.2
|
|
---------------------------
|
|
|
|
Gawk now uses autoconf 2.12.
|
|
|
|
strftime now behaves correctly if passed an empty format string or if
|
|
the string formats to an empty result string.
|
|
|
|
Several minor compilation and installation problems have been fixed.
|
|
|
|
Minor page break issues in the user's guide have been fixed.
|
|
|
|
Lexical errors no longer repeat ad infinitum.
|
|
|
|
Changes from 3.0.0 to 3.0.1
|
|
---------------------------
|
|
|
|
Troff source for a handy-dandy five color reference card is now provided.
|
|
Thanks to SSC for their macros.
|
|
|
|
Gawk now behaves like Unix awk and mawk, in that newline acts as white
|
|
space for separating fields and for `split', by default. In posix mode,
|
|
only space and tab separate fields. The documentation has been updated to
|
|
reflect this.
|
|
|
|
Tons and tons of small bugs fixed and new tests added, see the ChangeLogs.
|
|
|
|
Lots fewer compile time warnings from gcc -Wall. Remaining ones aren't
|
|
worth fixing.
|
|
|
|
Gawk now pays some attention to the locale settings.
|
|
|
|
Fixes to gsub to catch several corner cases.
|
|
|
|
The `print' statement now evaluates all expressions first, and then
|
|
prints them. This leads to less suprising behaviour if any expression has
|
|
output side effects.
|
|
|
|
Miscellanious improvements in regex.h and regex.c.
|
|
|
|
Gawk will now install itself as gawk-M.N.P in $(bindir), and link
|
|
`gawk' to it. This makes it easy to have multiple versions of gawk
|
|
simultaneously. It will also now install itself as `awk' in $(bindir)
|
|
if there is no `awk' there. This is in addition to installing itself as
|
|
`gawk'. This change benefits the Hurd, and possibly other systems. One
|
|
day, gawk will drop the `g', but not yet.
|
|
|
|
`--posix' turns on interval expressions. Gawk now matches its documentation.
|
|
|
|
`close(FILENAME)' now does something meaningful.
|
|
|
|
Field management code in field.c majorly overhauled, several times.
|
|
|
|
The gensub code has been fixed, several bugs are now gone.
|
|
|
|
Gawk will use mmap for data file input if it is available.
|
|
|
|
The printf/sprintf code has been improved.
|
|
|
|
Minor issues in Makefile setup worked on and improved.
|
|
|
|
builtin.c:do_substr rationalized.
|
|
|
|
Regex matching fixed so that /+[0-9]/ now matches the leading +.
|
|
|
|
For building on vms, the default compiler is now DEC C rather than VAX C.
|
|
|
|
Changes from 2.15.6 to 3.0.0
|
|
----------------------------
|
|
|
|
Fixed spelling of `Programming' in the copyright notice in all the files.
|
|
|
|
New --re-interval option to turn on interval expressions. They're off
|
|
by default, except for --posix, to avoid breaking old programs.
|
|
|
|
Passing regexp constants as parameters to user defined functions now
|
|
generates a lint warning.
|
|
|
|
Several obscure regexp bugs fixed; alas, a small number remain.
|
|
|
|
The manual has been thoroughly revised. It's now almost 50% bigger than
|
|
it used to be.
|
|
|
|
The `+' modifier in printf is now reset correctly for each item.
|
|
|
|
The do_unix variable is now named do_traditional.
|
|
|
|
Handling of \ in sub and gsub rationalized (somewhat, see the manual for
|
|
the gory [and I do mean gory] details).
|
|
|
|
IGNORECASE now uses ISO 8859-1 Latin-1 instead of straight ASCII. See the
|
|
source for how to revert to pure ASCII.
|
|
|
|
--lint will now warn if an assignment occurs in a conditional context.
|
|
This may become obnoxious enough to need turning off in the future, but
|
|
"it seemed like a good idea at the time."
|
|
|
|
%hf and %Lf are now diagnosed as invalid in printf, just like %lf.
|
|
|
|
Gawk no longer incorrectly closes stdin in child processes used in
|
|
input pipelines.
|
|
|
|
For integer formats, gawk now correctly treats the precision as the
|
|
number of digits to print, not the number of characters.
|
|
|
|
gawk is now much better at catching the use of scalar values when
|
|
arrays are needed, both in function calls and the `x in y' constructs.
|
|
|
|
New gensub function added. See the manual.
|
|
|
|
If do_tradtional is true, octal and hex escapes in regexp constants are
|
|
treated literally. This matches historical behavior.
|
|
|
|
yylex/nextc fixed so that even null characters can be included
|
|
in the source code.
|
|
|
|
do_format now handles cases where a format specifier doesn't end in
|
|
a control letter. --lint reports an error.
|
|
|
|
strftime() now uses a default time format equivalent to that of the
|
|
Unix date command, thus it can be called with no arguments.
|
|
|
|
Gawk now catches functions that are used but not defined at parse time
|
|
instead of at run time. (This is a lint error, making it fatal could break
|
|
old code.)
|
|
|
|
Arrays that max out are now handled correctly.
|
|
|
|
Integer formats outside the range of an unsigned long are now detected
|
|
correctly using the SunOS 4.x cc compiler.
|
|
|
|
--traditional option added as new preferred name for --compat, in keeping
|
|
with GCC.
|
|
|
|
--lint-old option added, so that warnings about things not in old awk
|
|
are only given if explicitly asked for.
|
|
|
|
`next file' has changed to one word, `nextfile'. `next file' is still
|
|
accepted but generates a lint warning. `next file' will go away eventually.
|
|
|
|
Gawk with --lint will now notice empty source files and empty data files.
|
|
|
|
Amiga support using the Unix emulation added. Thanks to fnf@ninemoons.com.
|
|
|
|
test/Makefile is now "parallel-make safe".
|
|
|
|
Gawk now uses POSIX regexps + GNU regex ops by default. --posix goes to
|
|
pure posix regexps, and --compat goes to traditional Unix regexps. However,
|
|
interval expressions, even though specified by POSIX, are turned off by
|
|
default, to avoid breaking old code.
|
|
|
|
IGNORECASE now applies to string comparison as well as regexp operations.
|
|
|
|
The AT&T Bell Labs Research awk fflush builtin function is now supported.
|
|
fflush is extended to flush stdout if no arg and everything if given
|
|
the null string as an argument.
|
|
|
|
If RS is more than one character, it is treated as a regular expression
|
|
and records are delimited accordingly. The variable RT is set to the record
|
|
terminator string. This is disabled in compatibility mode.
|
|
|
|
If FS is set to the null string (or the third arg. of split() is the null
|
|
string), splitting is done at every single character. This is disabled in
|
|
compatibility mode.
|
|
|
|
Gawk now uses the Autoconf generated configure script, doing away with all
|
|
the config/* files and the machinery that went with them. The Makefile.in
|
|
has also changed accordingly, complete with all the standard GNU Makefile
|
|
targets. (Non-unix systems may still have their own config.h and Makefile;
|
|
see the appropriate README_d/README.* and/or subdirectory.)
|
|
|
|
The source code has been cleaned up somewhat and the formatting improved.
|
|
|
|
Changes from 2.15.5 to 2.15.6
|
|
-----------------------------
|
|
|
|
Copyrights updated on all changed files.
|
|
|
|
test directory enhanced with four new tests.
|
|
|
|
Gawk now generates a warning for \x without following hexadecimal digits.
|
|
In this case, it returns 'x', not \0.
|
|
|
|
Several fixes in main.c related to variable initialization:
|
|
CONVFMT has a default value
|
|
resetup is called before initializing variables
|
|
the varinit table fixed up a bit (see the comments)
|
|
|
|
gawk.1 updated with new BUG REPORTS section.
|
|
|
|
A plain `print' inside a BEGIN or END now generates a lint warning (awk.y).
|
|
|
|
Small fix in iop.c:get_a_record to avoid reading uninitialized memory.
|
|
|
|
awk.y:yylex now does a better job of handling things if the source file
|
|
does not end in a newline. Probably there is more work to be done.
|
|
|
|
Memory leaks fixed in awk.y, particularly in cases of duplicate function
|
|
parameters. Also, calling a function doesn't leak memory during parsing.
|
|
|
|
Empty function bodies are now allowed (awk.y).
|
|
|
|
Gawk now detects duplicate parameter names in functions (awk.y).
|
|
|
|
New function `error' in msg.c added for use from awk.y.
|
|
|
|
eval.c:r_get_lhs now checks if its argument is a parameter on the stack,
|
|
and pulls down the real variable. This catches more 'using an array as
|
|
a scalar' kinds of errors.
|
|
|
|
main.c recovers C alloca space after parsing, this is important for
|
|
bison-based parsers. re.c recovers C alloca space after doing an research.
|
|
[Changes from Pat Rankin]
|
|
|
|
builtin.c now declares the random() related functions based on
|
|
RANDOM_MISSING from config.h. [Suggested by Pat Rankin]
|
|
|
|
awk.h now handles alloca correctly for HP-UX. [Kaveh Ghazi]
|
|
|
|
regex.h and config/cray60 updated for Unicos 8.0. [Hal Peterson]
|
|
|
|
Fixed re.c and dfa.c so that gawk no longer leaks memory when using
|
|
lots of dynamic regexps.
|
|
|
|
Removed dependency on signed chars from `idx' variable in awk.h. Gawk
|
|
now passes its test suite if compiled with `gcc -fno-signed-char'.
|
|
|
|
Fixed warning on close in io.c to go under lint control. Too many people
|
|
have complained about the spurious message, particularly when closing a
|
|
child pipeline early.
|
|
|
|
Gawk now correctly handles RS = "" when input is from a terminal
|
|
(iop.c:get_a_record).
|
|
|
|
Config file added for GNU.
|
|
|
|
gawk 'BEGIN { exit 1 } ; END { exit }' now exits 1, as it should
|
|
(eval.c:interpret).
|
|
|
|
sub and gsub now follow posix, \ escapes both & and \. Each \ must
|
|
be doubled initially in the program to get it into the string.
|
|
Thanks to Mike Brennan for pointing this out (builtin.c:sub_common).
|
|
|
|
If FS is "", gawk behaves like mawk and nawk, making the whole record be $1.
|
|
Yet Another Dark Corner. Sigh (field.c:def_parse_field).
|
|
|
|
Gawk now correctly recomputes string values for numbers if CONVFMT has
|
|
changed (awk.h:force_string, node.c:r_force_string).
|
|
|
|
A regexp of the form `/* this looks like a comment but is not */' will
|
|
now generate a warning from --lint (awk.y).
|
|
|
|
Gawk will no longer core dump if given an empty input file (awk.y:get_src_buf,
|
|
iop.c:optimal_bufsize).
|
|
|
|
A printf format of the form %lf is handled correctly. The `l' generates
|
|
a lint warning (builtin.c:format_tree) [Thanks to Mark Moraes].
|
|
|
|
Lynxos config file added.
|
|
|
|
`continue' outside a loop treated as `next' only in compatibility mode,
|
|
instead of by default; recent att nawk chokes on this now. `break'
|
|
outside a loop now treated as `next' in compatibility mode (eval.c).
|
|
|
|
Bug fix in string concatenation, an arbitrary number of expressions
|
|
are allowed (eval.c).
|
|
|
|
$1 += $2 now works correctly (eval.c).
|
|
|
|
Changing IGNORECASE no longer resets field-splitting to FS if it was
|
|
using FIELDWIDTHS (eval.c, field.c).
|
|
|
|
Major enhancement: $0 and NF for last record read are now preserved
|
|
into the END rule (io.c).
|
|
|
|
Regexp fixes:
|
|
/./ now matches a newline (regex.h)
|
|
^ and $ match beginning and end of string only, not any embedded
|
|
newlines (re.c)
|
|
regex.c should compile and work ok on 64-bit mips/sgi machines
|
|
|
|
Changes from 2.15.4 to 2.15.5
|
|
-----------------------------
|
|
|
|
FUTURES file updated and re-arranged some with more rational schedule.
|
|
|
|
Many prototypes handled better for ANSI C in protos.h.
|
|
|
|
getopt.c updated somewhat.
|
|
|
|
test/Makefile now removes junk directory, `bardargtest' renamed `badargs.'
|
|
|
|
Bug fix in iop.c for RS = "". Eat trailing newlines off of record separator.
|
|
|
|
Bug fix in Makefile.bsd44, use leading tab in actions.
|
|
|
|
Fix in field.c:set_FS for FS == "\\" and IGNORECASE != 0.
|
|
|
|
Config files updated or added:
|
|
cray60, DEC OSF/1 2.0, Utek, sgi405, next21, next30, atari/config.h,
|
|
sco.
|
|
|
|
Fix in io.c for ENFILE as well as EMFILE, update decl of groupset to
|
|
include OSF/1.
|
|
|
|
Rationalized printing as integers if numbers are outside the range of a long.
|
|
Changes to node.c:force_string and builtin.c.
|
|
|
|
Made internal NF, NR, and FNR variables longs instead of ints.
|
|
|
|
Add LIMITS_H_MISSING stuff to config.in and awk.h, and default defs for
|
|
INT_MAX and LONG_MAX, if no limits.h file. Add a standard decl of
|
|
the time() function for __STDC__. From ghazi@noc.rutgers.edu.
|
|
|
|
Fix tree_eval in awk.h and r_tree_eval in eval.c to deal better with
|
|
function parameters, particularly ones that are arrays.
|
|
|
|
Fix eval.c to print out array names of arrays used in scalar contexts.
|
|
|
|
Fix eval.c in interpret to zero out source and sourceline initially. This
|
|
does a better job of providing source file and line number information.
|
|
|
|
Fix to re_parse_field in field.c to not use isspace when RS = "", but rather
|
|
to explicitly look for blank and tab.
|
|
|
|
Fix to sc_parse_field in field.c to catch the case of the FS character at the
|
|
end of a record.
|
|
|
|
Lots of miscellanious bug fixes for memory leaks, courtesy Mark Moraes,
|
|
also fixes for arrays.
|
|
|
|
io.c fixed to warn about lack of explicit closes if --lint.
|
|
|
|
Updated missing/strftime.c to match posted strftime 6.2.
|
|
|
|
Bug fix in builtin.c, in case of non-match in sub_common.
|
|
|
|
Updated constant used for division in builtin.c:do_rand for DEC Alpha
|
|
and CRAY Y-MP.
|
|
|
|
POSIXLY_CORRECT in the environment turns on --posix (fixed in main.c).
|
|
|
|
Updated srandom prototype and calls in builtin.c.
|
|
|
|
Fix awk.y to enforce posix semantics of unary +: result is numeric.
|
|
|
|
Fix array.c to not rearrange the hash chain upon finding an index in
|
|
the array. This messed things up in cases like:
|
|
for (index1 in array) {
|
|
blah
|
|
if (index2 in array) # blew away the for
|
|
stuff
|
|
}
|
|
|
|
Fixed spelling errors in the man page.
|
|
|
|
Fixes in awk.y so that
|
|
gawk '' /path/to/file
|
|
will work without core dumping or finding parse errors.
|
|
|
|
Fix main.c so that --lint will fuss about an empty program.
|
|
Yet another fix for argument parsing in the case of unrecognized options.
|
|
|
|
Bug fix in dfa.c to not attempt to free null pointers.
|
|
|
|
Bug fix in builtin.c to only use DEFAULT_G_PRECISION for %g or %G.
|
|
|
|
Bug fix in field.c to achieve call by value semantics for split.
|
|
|
|
Changes from 2.15.3 to 2.15.4
|
|
-----------------------------
|
|
|
|
Lots of lint fixes, and do_sprintf made mostly ANSI C compatible.
|
|
|
|
Man page updated and edited.
|
|
|
|
Copyrights updated.
|
|
|
|
Arrays now grow dynamically, initially scaling up by an order of magnitude
|
|
and then doubling, up to ~ 64K. This should keep gawk's performance
|
|
graceful under heavy load.
|
|
|
|
New `delete array' feature added. Only documented in the man page.
|
|
|
|
Switched to dfa and regex suites from grep-2.0. These offer the ability to
|
|
move to POSIX regexps in the next release.
|
|
|
|
Disabled GNU regex ops.
|
|
|
|
Research awk -m option now recognized. It does nothing in gawk, since gawk
|
|
has no static limits. Only documented in the man page.
|
|
|
|
New bionic (faster, better, stronger than before) hashing function.
|
|
|
|
Bug fix in argument handling. `gawk -X' now notices there was no program.
|
|
Additional bug fixes to make --compat and --lint work again.
|
|
|
|
Many changes for systems where sizeof(int) != sizeof(void *).
|
|
|
|
Add explicit alloca(0) in io.c to recover space from C alloca.
|
|
|
|
Fixed file descriptor leak in io.c.
|
|
|
|
The --version option now follows the GNU coding standards and exits.
|
|
|
|
Fixed several prototypes in protos.h.
|
|
|
|
Several tests updated. On Solaris, warn that the out? tests will fail.
|
|
|
|
Configuration files for SunOS with cc and Solaris 2.x added.
|
|
|
|
Improved error messages in awk.y on gawk extensions if do_unix or do_compat.
|
|
|
|
INSTALL file added.
|
|
|
|
Fixed Atari Makefile and several VMS specific changes.
|
|
|
|
Better conversion of numbers to strings on systems with broken sprintfs.
|
|
|
|
Changes from 2.15.2 to 2.15.3
|
|
-----------------------------
|
|
|
|
Increased HASHSIZE to a decent number, 127 was way too small.
|
|
|
|
FILENAME is now the null string in a BEGIN rule.
|
|
|
|
Argument processing fixed for invalid options and missing arguments.
|
|
|
|
This version will build on VMS. This included a fix to close all files
|
|
and pipes opened with redirections before closing stdout and stderr.
|
|
|
|
More getpgrp() defines.
|
|
|
|
Changes for BSD44: <sys/param.h> in io.c and Makefile.bsd44.
|
|
|
|
All directories in the distribution are now writable.
|
|
|
|
Separated LDFLAGS and CFLAGS in Makefile. CFLAGS can now be overridden by
|
|
user.
|
|
|
|
Make dist now builds compressed archives ending in .gz and runs doschk.
|
|
|
|
Amiga port.
|
|
|
|
New getopt.c fixes Alpha OSF/1 problem.
|
|
|
|
Make clean now removes possible test output.
|
|
|
|
Improved algorithm for multiple adjacent string concatenations leads to
|
|
performance improvements.
|
|
|
|
Fix nasty bug whereby command-line assignments, both with -v and at run time,
|
|
could create variables with syntactically illegal names.
|
|
|
|
Fix obscure bug in printf with %0 flag and filling.
|
|
|
|
Add a lint check for substr if provided length exceeds remaining characters
|
|
in string.
|
|
|
|
Update atari support.
|
|
|
|
PC support enhanced to include support for both DOS and OS/2. (Lots more
|
|
#ifdefs. Sigh.)
|
|
|
|
Config files for Hitachi Unix and OSF/1, courtesy of Yoko Morishita
|
|
(morisita@sra.co.jp)
|
|
|
|
Changes from 2.15.1 to 2.15.2
|
|
-----------------------------
|
|
|
|
Additions to the FUTURES file.
|
|
|
|
Document undefined order of output when using both standard output
|
|
and /dev/stdout or any of the /dev output files that gawk emulates in
|
|
the absence of OS support.
|
|
|
|
Clean up the distribution generation in Makefile.in: the info files are
|
|
now included, the distributed files are marked read-only and patched
|
|
distributions are now unpacked in a directory named with the patch level.
|
|
|
|
Changes from 2.15 to 2.15.1
|
|
---------------------------
|
|
|
|
Close stdout and stderr before all redirections on program exit. This allows
|
|
detection of write errors and also fixes the messages test on Solaris 2.x.
|
|
|
|
Removed YYMAXDEPTH define in awk.y which was limiting the parser stack depth.
|
|
|
|
Changes to config/bsd44, Makefile.bsd44 and configure to bring it into line
|
|
with the BSD4.4 release.
|
|
|
|
Changed Makefile to use prefix, exec_prefix, bindir etc.
|
|
|
|
make install now installs info files.
|
|
|
|
make install now sets permissions on installed files.
|
|
|
|
Make targets added: uninstall, distclean, mostlyclean and realclean.
|
|
|
|
Added config.h to cleaner and clobber make targets.
|
|
|
|
Changes to config/{hpux8x,sysv3,sysv4,ultrix41} to deal with alloca().
|
|
|
|
Change to getopt.h for portability.
|
|
|
|
Added more special cases to the getpgrp() call.
|
|
|
|
Added README.ibmrt-aos and config/ibmrt-aos.
|
|
|
|
Changes from 2.14 to 2.15
|
|
---------------------------
|
|
|
|
Command-line source can now be mixed with library functions.
|
|
|
|
ARGIND variable tracks index in ARGV of FILENAME.
|
|
|
|
GNU style long options in addition to short options.
|
|
|
|
Plan 9 style special files interpreted by gawk:
|
|
/dev/pid
|
|
/dev/ppid
|
|
/dev/pgrpid
|
|
/dev/user
|
|
$1 = getuid
|
|
$2 = geteuid
|
|
$3 = getgid
|
|
$4 = getegid
|
|
$5 ... $NF = getgroups if supported
|
|
|
|
ERRNO variable contains error string if getline or close fails.
|
|
|
|
Very old options -a and -e have gone away.
|
|
|
|
Inftest has been removed from the default target in test/Makefile -- the
|
|
results were too machine specific and resulted in too many false alarms.
|
|
|
|
A README.amiga has been added.
|
|
|
|
The "too many arguments supplied for format string" warning message is only
|
|
in effect under the lint option.
|
|
|
|
Code improvements in dfa.c.
|
|
|
|
Fixed all reported bugs:
|
|
|
|
Writes are checked for failure (such as full filesystem).
|
|
|
|
Stopped (at least some) runaway error messages.
|
|
|
|
gsub(/^/, "x") does the right thing for $0 of 0, 1, or more length.
|
|
|
|
close() on a command being piped to a getline now works properly.
|
|
|
|
The input record will no longer be freed upon an explicit close()
|
|
of the input file.
|
|
|
|
A NUL character in FS now works.
|
|
|
|
In a substitute, \\& now means a literal backslash followed by what
|
|
was matched.
|
|
|
|
Integer overflow of substring length in substr() is caught.
|
|
|
|
An input record without a newline termination is handled properly.
|
|
|
|
In io.c, check is against only EMFILE so that system file table
|
|
is not filled.
|
|
|
|
Renamed all files with names longer than 14 characters.
|
|
|
|
Escaped characters in regular expressions were being lost when
|
|
IGNORECASE was used.
|
|
|
|
Long source lines were not being handled properly.
|
|
|
|
Sourcefiles that ended in a tab but no newline were bombing.
|
|
|
|
Patterns that could match zero characters in split() were not working
|
|
properly.
|
|
|
|
The parsedebug option was not working.
|
|
|
|
The grammar was being a bit too lenient, allowing some very dubious
|
|
programs to pass.
|
|
|
|
Compilation with DEBUG defined now works.
|
|
|
|
A variable read in with getline was not being treated as a potential
|
|
number.
|
|
|
|
Array subscripts were not always of string type.
|
|
|
|
|
|
Changes from 2.13.2 to 2.14
|
|
---------------------------
|
|
|
|
Updated manual!
|
|
|
|
Added "next file" to skip efficiently to the next input file.
|
|
|
|
Fixed potential of overflowing buffer in do_sprintf().
|
|
|
|
Plugged small memory leak in sub_common().
|
|
|
|
EOF on a redirect is now "sticky" -- it can only be cleared by close()ing
|
|
the pipe or file.
|
|
|
|
Now works if used via a #! /bin/gawk line at the top of an executable file
|
|
when that line ends with whitespace.
|
|
|
|
Added some checks to the grammar to catch redefinition of builtin functions.
|
|
This could eventually be the basis for an extension to allow redefining
|
|
functions, but in the mean time it's a good error catching facility.
|
|
|
|
Negative integer exponents now work.
|
|
|
|
Modified do_system() to make sure it had a non-null string to be passed
|
|
to system(3). Thus, system("") will flush any pending output but not go
|
|
through the overhead of forking an un-needed shell.
|
|
|
|
A fix to floating point comparisons so that NaNs compare right on IEEE systems.
|
|
|
|
Added code to make sure we're not opening directories for reading and such.
|
|
|
|
Added code to do better diagnoses of weird or null file names.
|
|
|
|
Allow continue outside of a loop, unless in strict posix mode. Lint option
|
|
will issue warning.
|
|
|
|
New missing/strftime.c. There has been one change that affects gawk. Posix
|
|
now defines a %V conversion so the vms conversion has been changed to %v.
|
|
If this version is used with gawk -Wlint and they use %V in a call to
|
|
strftime, they'll get a warning.
|
|
|
|
Error messages now conform to GNU standard (I hope).
|
|
|
|
Changed comparisons to conform to the description found in the file POSIX.
|
|
This is inconsistent with the current POSIX draft, but that is broken.
|
|
Hopefully the final POSIX standard will conform to this version.
|
|
(Alas, this will have to wait for 1003.2b, which will be a revision to
|
|
the 1003.2 standard. That standard has been frozen with the broken
|
|
comparison rules.)
|
|
|
|
The length of a string was a short and now is a size_t.
|
|
|
|
Updated VMS help.
|
|
|
|
Added quite a few new tests to the test suite and deleted many due to lack of
|
|
written releases. Test output is only removed if it is identical to the
|
|
"good" output.
|
|
|
|
Fixed a couple of bugs for reference to $0 when $0 is "" -- particularly in
|
|
a BEGIN block.
|
|
|
|
Fixed premature freeing in construct "$0 = $0".
|
|
|
|
Removed the call to wait_any() in gawk_popen(), since on at least some systems,
|
|
if gawk's input was from a pipe, the predecessor process in the pipe was a
|
|
child of gawk and this caused a deadlock.
|
|
|
|
Regexp can (once again) match a newline, if given explicitly.
|
|
|
|
nextopen() makes sure file name is null terminated.
|
|
|
|
Fixed VMS pipe simulation. Improved VMS I/O performance.
|
|
|
|
Catch . used in variable names.
|
|
|
|
Fixed bug in getline without redirect from a file -- it was quitting after the
|
|
first EOF, rather than trying the next file.
|
|
|
|
Fixed bug in treatment of backslash at the end of a string -- it was bombing
|
|
rather than doing something sensible. It is not clear what this should mean,
|
|
but for now I issue a warning and take it as a literal backslash.
|
|
|
|
Moved setting of regexp syntax to before the option parsing in main(), to
|
|
handle things like -v FS='[.,;]'
|
|
|
|
Fixed bug when NF is set by user -- fields_arr must be expanded if necessary
|
|
and "new" fields must be initialized.
|
|
|
|
Fixed several bugs in [g]sub() for no match found or the match is 0-length.
|
|
|
|
Fixed bug where in gsub() a pattern anchored at the beginning would still
|
|
substitute throughout the string.
|
|
|
|
make test does not assume that . is in PATH.
|
|
|
|
Fixed bug when a field beyond the end of the record was requested after
|
|
$0 was altered (directly or indirectly).
|
|
|
|
Fixed bug for assignment to field beyond end of record -- the assigned value
|
|
was not found on subsequent reference to that field.
|
|
|
|
Fixed bug for FS a regexp and it matches at the end of a record.
|
|
|
|
Fixed memory leak for an array local to a function.
|
|
|
|
Fixed hanging of pipe redirection to getline
|
|
|
|
Fixed coredump on access to $0 inside BEGIN block.
|
|
|
|
Fixed treatment of RS = "". It now parses the fields correctly and strips
|
|
leading whitespace from a record if FS is a space.
|
|
|
|
Fixed faking of /dev/stdin.
|
|
|
|
Fixed problem with x += x
|
|
|
|
Use of scalar as array and vice versa is now detected.
|
|
|
|
IGNORECASE now obeyed for FS (even if FS is a single alphabetic character).
|
|
|
|
Switch to GPL version 2.
|
|
|
|
Renamed awk.tab.c to awktab.c for MSDOS and VMS tar programs.
|
|
|
|
Renamed this file (CHANGES) to NEWS.
|
|
|
|
Use fmod() instead of modf() and provide FMOD_MISSING #define to undo
|
|
this change.
|
|
|
|
Correct the volatile declarations in eval.c.
|
|
|
|
Avoid errant closing of the file descriptors for stdin, stdout and stderr.
|
|
|
|
Be more flexible about where semi-colons can occur in programs.
|
|
|
|
Check for write errors on all output, not just on close().
|
|
|
|
Eliminate the need for missing/{strtol.c,vprintf.c}.
|
|
|
|
Use GNU getopt and eliminate missing/getopt.c.
|
|
|
|
More "lint" checking.
|
|
|
|
|
|
Changes from 2.13.1 to 2.13.2
|
|
-----------------------------
|
|
|
|
Toward conformity with GNU standards, configure is a link to mkconf, the latter
|
|
to disappear in the next major release.
|
|
|
|
Update to config/bsd43.
|
|
|
|
Added config/apollo, config/msc60, config/cray2-50, config/interactive2.2
|
|
|
|
sgi33.cc added for compilation using cc rather than gcc.
|
|
|
|
Ultrix41 now propagates to config.h properly -- as part of a general
|
|
mechanism in configure for kludges -- #define anything from a config file
|
|
just gets tacked onto the end of config.h -- to be used sparingly.
|
|
|
|
Got rid of an unnecessary and troublesome declaration of vprintf().
|
|
|
|
Small improvement in locality of error messages.
|
|
|
|
Try to diagnose use of array as scalar and vice versa -- to be improved in
|
|
the future.
|
|
|
|
Fix for last bug fix for Cray division code--sigh.
|
|
|
|
More changes to test suite to explicitly use sh. Also get rid of
|
|
a few generated files.
|
|
|
|
Fixed off-by-one bug in string concatenation code.
|
|
|
|
Fix for use of array that is passed in from a previous function parameter.
|
|
Addition to test suite for above.
|
|
|
|
A number of changes associated with changing NF and access to fields
|
|
beyond the end of the current record.
|
|
|
|
Change to missing/memcmp.c to avoid seg. fault on zero length input.
|
|
|
|
Updates to test suite (including some inadvertently left out of the last patch)
|
|
to invoke sh explicitly (rather than rely on #!/bin/sh) and remove some
|
|
junk files. test/chem/good updated to correspond to bug fixes.
|
|
|
|
Changes from 2.13.0 to 2.13.1
|
|
-----------------------------
|
|
|
|
More configs and PORTS.
|
|
|
|
Fixed bug wherein a simple division produced an erroneous FPE, caused by
|
|
the Cray division workaround -- that code is now #ifdef'd only for
|
|
Cray *and* fixed.
|
|
|
|
Fixed bug in modulus implementation -- it was very close to the above
|
|
code, so I noticed it.
|
|
|
|
Fixed portability problem with limits.h in missing.c
|
|
|
|
Fixed portability problem with tzname and daylight -- define TZNAME_MISSING
|
|
if strftime() is missing and tzname is also.
|
|
|
|
Better support for Latin-1 character set.
|
|
|
|
Fixed portability problem in test Makefile.
|
|
|
|
Updated PROBLEMS file.
|
|
|
|
=============================== gawk-2.13 released =========================
|
|
Changes from 2.12.42 to 2.12.43
|
|
-------------------------------
|
|
|
|
Typo in awk.y

Fixed up strftime.3 and added doc. for %V.
|
|
|
|
Changes from 2.12.41 to 2.12.42
|
|
-------------------------------
|
|
|
|
Fixed bug in devopen() -- if you had write permission in /dev,
|
|
it would just create /dev/stdout etc.!!
|
|
|
|
Final (?) VMS update.
|
|
|
|
Make NeXT use GFMT_WORKAROUND
|
|
|
|
Fixed bug in sub_common() for substitute on zero-length match. Improved the
|
|
code a bit while I was at it.
|
|
|
|
Fixed grammar so that $i++ parses as ($i)++
|
|
|
|
Put support/* back in the distribution (didn't I already do this?!)
|
|
|
|
Changes from 2.12.40 to 2.12.41
|
|
-------------------------------
|
|
|
|
VMS workaround for broken %g format.
|
|
|
|
Changes from 2.12.39 to 2.12.40
|
|
-------------------------------
|
|
|
|
Minor man page update.
|
|
|
|
Fixed latent bug in redirect().
|
|
|
|
Changes from 2.12.38 to 2.12.39
|
|
-------------------------------
|
|
|
|
Updates to test suite -- remove dependence on changing gawk.1 man page.
|
|
|
|
Changes from 2.12.37 to 2.12.38
|
|
-------------------------------
|
|
|
|
Fixed bug in use of *= without whitespace following.
|
|
|
|
VMS update.
|
|
|
|
Updates to man page.
|
|
|
|
Option handling updates in main.c
|
|
|
|
test/manyfiles redone and added to bigtest.
|
|
|
|
Fixed latent (on Sun) bug in handling of save_fs.
|
|
|
|
Changes from 2.12.36 to 2.12.37
|
|
-------------------------------
|
|
|
|
Update REL in Makefile-dist. Incorporate test suite into main distribution.
|
|
|
|
Minor fix in regtest.
|
|
|
|
Changes from 2.12.35 to 2.12.36
|
|
-------------------------------
|
|
|
|
Release takes on dual personality -- 2.12.36 and 2.13.0 -- any further
|
|
patches before public release won't count for 2.13, although they will for
|
|
2.12 -- be careful to avoid confusion! patchlevel.h will be the last thing
|
|
to change.
|
|
|
|
Cray updates to deal with arithmetic problems.
|
|
|
|
Minor test suite updates.
|
|
|
|
Fixed latent bug in parser (freeing memory).
|
|
|
|
Changes from 2.12.34 to 2.12.35
|
|
-------------------------------
|
|
|
|
VMS updates.
|
|
|
|
Flush stdout at top of err() and stderr at bottom.
|
|
|
|
Fixed bug in eval_condition() -- it wasn't testing for MAYBE_NUM and
|
|
doing the force_number().
|
|
|
|
Included the missing manyfiles.awk and a new test to catch the above bug which
|
|
I am amazed wasn't already caught by the test suite -- it's pretty basic.
|
|
|
|
Changes from 2.12.33 to 2.12.34
|
|
-------------------------------
|
|
|
|
Atari updates -- including bug fix.
|
|
|
|
More VMS updates -- also nuke vms/version.com.
|
|
|
|
Fixed bug in handling of large numbers of redirections -- it was probably never
|
|
tested before (blush!).
|
|
|
|
Minor rearrangement of code in r_force_number().
|
|
|
|
Made chem and regtest tests a bit more portable (Ultrix again).
|
|
|
|
Added another test -- manyfiles -- not invoked under any other test -- very Unix
|
|
specific.
|
|
|
|
Rough beginning of LIMITATIONS file -- need my AWK book to complete it.
|
|
|
|
Changes from 2.12.32 to 2.12.33
|
|
-------------------------------
|
|
|
|
Expunge debug.? from various files.
|
|
|
|
Remove vestiges of Floor and Ceil kludge.
|
|
|
|
Special case integer division -- mainly for Cray, but maybe someone else
|
|
will benefit.
|
|
|
|
Workaround for iop_close closing an output pipe descriptor on Cray --
|
|
not conditional since I think it may fix a bug on SGI as well and I don't
|
|
think it can hurt elsewhere.
|
|
|
|
Fixed memory leak in assoc_lookup().
|
|
|
|
Small cleanup in test suite.
|
|
|
|
Changes from 2.12.31 to 2.12.32
|
|
-------------------------------
|
|
|
|
Nuked debug.c and debugging flag -- there are better ways.
|
|
|
|
Nuked version.sh and version.c in subdirectories.
|
|
|
|
Fixed bug in handling of IGNORECASE.
|
|
|
|
Fixed bug when FIELDWIDTHS was set via -v option.
|
|
|
|
Fixed (obscure) bug when $0 is assigned a numerical value.
|
|
|
|
Fixed so that escape sequences in command-line assignments work (as it already
|
|
said in the comment).
|
|
|
|
Added a few cases to test suite.
|
|
|
|
Moved support/* back into distribution.
|
|
|
|
VMS updates.
|
|
|
|
Changes from 2.12.30 to 2.12.31
|
|
-------------------------------
|
|
|
|
Cosmetic manual page changes.
|
|
|
|
Updated sunos3 config.
|
|
|
|
Small changes in test suite including renaming files over 14 chars. in length.
|
|
|
|
Changes from 2.12.29 to 2.12.30
|
|
-------------------------------
|
|
|
|
Bug fix for many string concatenations in a row.
|
|
|
|
Changes from 2.12.28 to 2.12.29
|
|
-------------------------------
|
|
|
|
Minor cleanup in awk.y
|
|
|
|
Minor VMS update.
|
|
|
|
Minor atari update.
|
|
|
|
Changes from 2.12.27 to 2.12.28
|
|
-------------------------------
|
|
|
|
Got rid of the debugging goop in eval.c -- there are better ways.
|
|
|
|
Sequent port.
|
|
|
|
VMS changes left out of the last patch -- sigh! config/vms.h renamed
|
|
to config/vms-conf.h.
|
|
|
|
Fixed missing/tzset.c
|
|
|
|
Removed use of gcvt() and GCVT_MISSING -- turns out it was no faster than
|
|
sprintf("%g") and caused all sorts of portability headaches.
|
|
|
|
Tuned get_field() -- it was unnecessarily parsing the whole record on reference
|
|
to $0.
|
|
|
|
Tuned interpret() a bit in the rule_node loop.
|
|
|
|
In r_force_number(), worked around bug in Uglix strtod() and got rid of
|
|
ugly do{}while(0) at Michal's urging.
|
|
|
|
Replaced do_deref() and deref with unref(node) -- much cleaner and a bit faster.
|
|
|
|
Got rid of assign_number() -- contrary to comment, it was no faster than
|
|
just making a new node and freeing the old one.
|
|
|
|
Replaced make_number() and tmp_number() with macros that call mk_number().
|
|
|
|
Changed freenode() and newnode() into macros -- the latter is getnode()
|
|
which calls more_nodes() as necessary.
|
|
|
|
Changes from 2.12.26 to 2.12.27
|
|
-------------------------------
|
|
|
|
Completion of Cray 2 port (includes a kludge for floor() and ceil()
|
|
that may go or be changed -- I think that it may just be working around
|
|
a bug in chem that is being tweaked on the Cray).
|
|
|
|
More VMS updates.
|
|
|
|
Moved kludge over yacc's insertion of malloc and realloc declarations
|
|
from protos.h to the Makefile.
|
|
|
|
Added a lisp interpreter in awk to the test suite. (Invoked under
|
|
bigtest.)
|
|
|
|
Cleanup in r_force_number() -- I had never gotten around to a thorough
|
|
profile of the cache code and it turns out to be not worth it.
|
|
|
|
Performance boost -- do lazy force_number()'ing for fields etc. i.e.
|
|
flag them (MAYBE_NUM) and call force_number only as necessary.
|
|
|
|
Changes from 2.12.25 to 2.12.26
|
|
-------------------------------
|
|
|
|
Rework of regexp stuff so that dynamic regexps have reasonable
|
|
performance -- string used for compiled regexp is stored and
|
|
compared to new string -- if same, no recompilation is necessary.
|
|
Also, very dynamic regexps cause dfa-based searching to be turned
|
|
off.
|
|
|
|
Code in dev_open() is back to returning fileno(std*) rather than
|
|
dup()ing it. This will be documented. Sorry for the run-around
|
|
on this.
|
|
|
|
Minor atari updates.
|
|
|
|
Minor vms update.
|
|
|
|
Missing file from MSDOS port.
|
|
|
|
Added warning (under lint) if third arg. of [g]sub is a constant and
|
|
handle it properly in the code (i.e. return how many matches).
|
|
|
|
Changes from 2.12.24 to 2.12.25
|
|
-------------------------------
|
|
|
|
MSDOS port.
|
|
|
|
Non-consequential changes to regexp variables in preparation for
|
|
a more serious change to fix a serious performance problem.
|
|
|
|
Changes from 2.12.23 to 2.12.24
|
|
-------------------------------
|
|
|
|
Fixed bug in output flushing introduced a few patches back. This caused
|
|
serious performance losses.
|
|
|
|
Changes from 2.12.22 to 2.12.23
|
|
-------------------------------
|
|
|
|
Accidentally left config/cray2-60 out of last patch.
|
|
|
|
Added some missing dependencies to Makefile.
|
|
|
|
Cleaned up mkconf a bit; made yacc the default parser (no alloca needed,
|
|
right?); added rs6000 hook for signed characters.
|
|
|
|
Made regex.c with NO_ALLOCA undefined work.
|
|
|
|
Fixed bug in dfa.c for systems where free(NULL) bombs.
|
|
|
|
Deleted a few cant_happen()'s that *really* can't hapen.
|
|
|
|
Changes from 2.12.21 to 2.12.22
|
|
-------------------------------
|
|
|
|
Added to config stuff the ability to choose YACC rather than bison.
|
|
|
|
Fixed CHAR_UNSIGNED in config.h-dist.
|
|
|
|
Second arg. of strtod() is char ** rather than const char **.
|
|
|
|
stackb is now initially malloc()'ed since it may be realloc()'ed.
|
|
|
|
VMS updates.
|
|
|
|
Added SIZE_T_MISSING to config stuff and a default typedef to awk.h.
|
|
(Maybe it is not needed on any current systems??)
|
|
|
|
re_compile_pattern()'s size is now size_t unconditionally.
|
|
|
|
Changes from 2.12.20 to 2.12.21
|
|
-------------------------------
|
|
|
|
Corrected missing/gcvt.c.
|
|
|
|
Got rid of use of dup2() and thus DUP_MISSING.
|
|
|
|
Updated config/sgi33.
|
|
|
|
Turned on (and fixed) in cmp_nodes() the behaviour that I *hope* will be in
|
|
POSIX 1003.2 for relational comparisons.
|
|
|
|
Small updates to test suite.
|
|
|
|
Changes from 2.12.19 to 2.12.20
|
|
-------------------------------
|
|
|
|
Sloppy, sloppy, sloppy!! I didn't even try to compile the last two
|
|
patches. This one fixes goofs in regex.c.
|
|
|
|
Changes from 2.12.18 to 2.12.19
|
|
-------------------------------
|
|
|
|
Cleanup of last patch.
|
|
|
|
Changes from 2.12.17 to 2.12.18
|
|
-------------------------------
|
|
|
|
Makefile renamed to Makefile-dist.
|
|
|
|
Added alloca() configuration to mkconf. (A bit kludgey.) Just
|
|
add a single line containing ALLOCA_PW, ALLOCA_S or ALLOCA_C
|
|
to the appropriate config file to have Makefile-dist edited
|
|
accordingly.
|
|
|
|
Reorganized output flushing to correspond with new semantics of
|
|
devopen() on "/dev/std*" etc.
|
|
|
|
Fixed rest of last goof!!
|
|
|
|
Save and restore errno in do_pathopen().
|
|
|
|
Miscellaneous atari updates.
|
|
|
|
Get rid of the trailing comma in the NODETYPE definition (Cray
|
|
compiler won't take it).
|
|
|
|
Try to make the use of `const' consistent since Cray compiler is
|
|
fussy about that. See the changes to `basename' and `myname'.
|
|
|
|
It turns out that, according to section 3.8.3 (Macro Replacement)
|
|
of the ANSI Standard: ``If there are sequences of preprocessing
|
|
tokens within the list of arguments that would otherwise act as
|
|
preprocessing directives, the behavior is undefined.'' That means
|
|
that you cannot count on the behavior of the declaration of
|
|
re_compile_pattern in awk.h, and indeed the Cray compiler chokes on it.
|
|
|
|
Replaced alloca with malloc/realloc/free in regex.c. It was much simpler
|
|
than expected. (Inside NO_ALLOCA for now -- by default no alloca.)
|
|
|
|
Added a configuration file, config/cray60, for Unicos-6.0.
|
|
|
|
Changes from 2.12.16 to 2.12.17
|
|
-------------------------------
|
|
|
|
Ooops. Goofed signal use in last patch.
|
|
|
|
Changes from 2.12.15 to 2.12.16
|
|
-------------------------------
|
|
|
|
RENAMED *_dir to just * (e.g. missing_dir).
|
|
|
|
Numerous VMS changes.
|
|
|
|
Proper inclusion of atari and vms files.
|
|
|
|
Added experimental (ifdef'd out) RELAXED_CONTINUATION and DEFAULT_FILETYPE
|
|
-- please comment on these!
|
|
|
|
Moved pathopen() to io.c (sigh).
|
|
|
|
Put local directory ahead in default AWKPATH.
|
|
|
|
Added facility in mkconf to echo comments on stdout: lines beginning
|
|
with "#echo " will have the remainder of the line echoed when mkconf is run.
|
|
Any lines starting with "#" will otherwise be treated as comments. The
|
|
intent is to be able to say:
|
|
"#echo Make sure you uncomment alloca.c in the Makefile"
|
|
or the like.
|
|
|
|
Prototype fix for V.4
|
|
|
|
Fixed version_string to not print leading @(#).
|
|
|
|
Fixed FIELDWIDTHS to work with strict (turned out to be easy).
|
|
|
|
Fixed conf for V.2.
|
|
|
|
Changed semantics of /dev/fd/n to be like on real /dev/fd.
|
|
|
|
Several configuration and updates in the makefile.
|
|
|
|
Updated manpage.
|
|
|
|
Include tzset.c and system.c from missing_dir that were accidently left out of
|
|
the last patch.
|
|
|
|
Fixed bug in cmdline variable assignment -- arg was getting freed(!) in
|
|
call to variable.
|
|
|
|
Backed out of parse-time constant folding for now, until I can figure out
|
|
how to do it right.
|
|
|
|
Fixed devopen() so that getline <"-" works.
|
|
|
|
Changes from 2.12.14 to 2.12.15
|
|
-------------------------------
|
|
|
|
Changed config/* to a condensed form that can be used with mkconf to generate
|
|
a config.h from config.h-dist -- much easier to maintain. Please check
|
|
carefully against what you had before for a particular system and report
|
|
any problems. vms.h remains separate since the stuff at the bottom
|
|
didn't quite fit the mkconf model -- hopefully cleared up later.
|
|
|
|
Fixed bug in grammar -- didn't allow function definition to be separated from
|
|
other rules by a semi-colon.
|
|
|
|
VMS fix to #includes in missing.c -- should we just be including awk.h?
|
|
|
|
Updated README for texinfo.tex version.
|
|
|
|
Updating of copyright in all .[chy] files.
|
|
|
|
Added but commented out Michal's fix to strftime.
|
|
|
|
Added tzset() emulation based on Rick Adams' code. Added TZSET_MISSING to
|
|
config.h-dist.
|
|
|
|
Added strftime.3 man page for missing_dir
|
|
|
|
More posix: func, **, **= don't work in -W posix
|
|
|
|
More lint: ^, ^= not in old awk
|
|
|
|
gawk.1: removed ref to -DNO_DEV_FD, other minor updating.
|
|
|
|
Style change: pushbak becomes pushback() in yylex().
|
|
|
|
Changes from 2.12.13 to 2.12.14
|
|
-------------------------------
|
|
|
|
Better (?) organization of awk.h -- attempt to keep all system dependencies
|
|
near the top and move some of the non-general things out of the config.h
|
|
files.
|
|
|
|
Change to handling of SYSTEM_MISSING.
|
|
|
|
Small change to ultrix config.
|
|
|
|
Do "/dev/fd/*" etc. checking at runtime.
|
|
|
|
First pass at VMS port.
|
|
|
|
Improvements to error handling (when lexeme spans buffers).
|
|
|
|
Fixed backslash handling -- why didn't I notice this sooner?
|
|
|
|
Added programs from book to test suite and new target "bigtest" to Makefile.
|
|
|
|
Changes from 2.12.12 to 2.12.13
|
|
-------------------------------
|
|
|
|
Recognize OFS and ORS specially so that OFS = 9 works without efficiency hit.
|
|
Took advantage of opportunity to tune do_print*() for about 10% win on a
|
|
print with 5 args (i.e. small but significant).
|
|
|
|
Somewhat pervasive changes to reconcile CONVFMT vs. OFMT.
|
|
|
|
Better initialization of builtin vars.
|
|
|
|
Make config/* consistent wrt STRTOL_MISSING.
|
|
|
|
Small portability improvement to alloca.s
|
|
|
|
Improvements to lint code in awk.y
|
|
|
|
Replaced strtol() with a better one by Chris Torek.
|
|
|
|
Changes from 2.12.11 to 2.12.12
|
|
-------------------------------
|
|
|
|
Added PORTS file to record successful ports.
|
|
|
|
Added #define const to nothing if not STDC and added const to strtod() header.
|
|
|
|
Added * to printf capabilities and partially implemented ' ' and '+' (has an
|
|
effect for %d only, silently ignored for other formats). I'm afraid that's
|
|
as far as I want to go before I look at a complete replacement for
|
|
do_sprintf().
|
|
|
|
Added warning for /regexp/ on LHS of MATCHOP.
|
|
|
|
Changes from 2.12.10 to 2.12.11
|
|
-------------------------------
|
|
|
|
Small Makefile improvements.
|
|
|
|
Some remaining nits from the NeXT port.
|
|
|
|
Got rid of bcopy() define in awk.h -- not needed anymore (??)
|
|
|
|
Changed private in builtin.c -- it is special on Sequent.
|
|
|
|
Added subset implementation of strtol() and STRTOL_MISSING.
|
|
|
|
A little bit of cleanup in debug.c, dfa.c.
|
|
|
|
Changes from 2.12.9 to 2.12.10
|
|
------------------------------
|
|
|
|
Redid compatability checking and checking for # of args.
|
|
|
|
Removed all references to variables[] from outside awk.y, in preparation
|
|
for a more abstract interface to the symbol table.
|
|
|
|
Got rid of a remaining use of bcopy() in regex.c.
|
|
|
|
Changes from 2.12.8 to 2.12.9
|
|
-----------------------------
|
|
|
|
Portability improvements for atari, next and decstation.
|
|
|
|
Bug fix in substr() -- wasn't handling 3rd arg. of -1 properly.
|
|
|
|
Manpage updates.
|
|

|
Changes from 2.12.2 to 2.12.3
|
|
-----------------------------

Brought regex.c and alloca.s into line with current FSF versions.
|
|
|
|
Changes from 2.12.1 to 2.12.2
|
|
-----------------------------
|
|
|
|
Portability improvements; mostly moving system prototypes out of awk.h
|
|
|
|
Introduction of strftime.
|
|
|
|
Use of CONVFMT.
|
|
|
|
Changes from 2.12 to 2.12.1
|
|
-----------------------------
|
|
|
|
Consolidated treatment of command-line assignments (thus correcting the
|
|
-v treatment).
|
|
|
|
Rationalized builtin-variable handling into a table-driven process, thus
|
|
simplifying variable() and eliminating spc_var().
|
|
|
|
Fixed bug in handling of command-line source that ended in a newline.
|
|
|
|
Simplified install() and lookup().
|
|
|
|
Did away with double-mallocing of identifiers and now free second and later
|
|
instances of a name, after the first gets installed into the symbol table.
|
|
|
|
Treat IGNORECASE specially, simplifying a lot of code, and allowing
|
|
checking against strict conformance only on setting it, rather than on each
|
|
pattern match.
|
|
|
|
Fixed regexp matching when IGNORECASE is non-zero (broken when dfa.c was
|
|
added).
|
|
|
|
Fixed bug where $0 was not being marked as valid, even after it was rebuilt.
|
|
This caused mangling of $0.
|
|
|
|
|
|
Changes from 2.11.1 to 2.12
|
|
-----------------------------
|
|
|
|
Makefile:
|
|
|
|
Portability improvements in Makefile.
|
|
Move configuration stuff into config.h
|
|
|
|
FSF files:
|
|
|
|
Synchronized alloca.[cs] and regex.[ch] with FSF.
|
|
|
|
array.c:
|
|
|
|
Rationalized hash routines into one with a different algorithm.
|
|
delete() now works if the array is a local variable.
|
|
Changed interface of assoc_next() and avoided dereferencing past the end of the
|
|
array.
|
|
|
|
awk.h:
|
|
|
|
Merged non-prototype and prototype declarations in awk.h.
|
|
Expanded tree_eval #define to short-circuit more calls of r_tree_eval().
|
|
|
|
awk.y:
|
|
|
|
Delinted some of the code in the grammar.
|
|
Fixed and improved some of the error message printing.
|
|
Changed to accomodate unlimited length source lines.
|
|
Line continuation now works as advertised.
|
|
Source lines can be arbitrarily long.
|
|
Refined grammar hacks so that /= assignment works. Regular expressions
|
|
starting with /= are recognized at the beginning of a line, after && or ||
|
|
and after ~ or !~. More contexts can be added if necessary.
|
|
Fixed IGNORECASE (multiple scans for backslash).
|
|
Condensed expression_lists in array references.
|
|
Detect and warn for correct # args in builtin functions -- call most of them
|
|
with a fixed number (i.e. fill in defaults at parse-time rather than at
|
|
run-time).
|
|
Load ENVIRON only if it is referenced (detected at parse-time).
|
|
Treat NF, FS, RS, NR, FNR specially at parse time, to improve run time.
|
|
Fold constant expressions at parse time.
|
|
Do make_regexp() on third arg. of split() at parse tiem if it is a constant.
|
|
|
|
builtin.c:
|
|
|
|
srand() returns 0 the first time called.
|
|
Replaced alloca() with malloc() in do_sprintf().
|
|
Fixed setting of RSTART and RLENGTH in do_match().
|
|
Got rid of get_{one,two,three} and allowance for variable # of args. at
|
|
run-time -- this is now done at parse-time.
|
|
Fixed latent bug in [g]sub whereby changes to $0 would never get made.
|
|
Rewrote much of sub_common() for simplicity and performance.
|
|
Added ctime() and time() builtin functions (unless -DSTRICT). ctime() returns
|
|
a time string like the C function, given the number of seconds since the epoch
|
|
and time() returns the current time in seconds.
|
|
do_sprintf() now checks for mismatch between format string and number of
|
|
arguments supplied.
|
|
|
|
dfa.c
|
|
|
|
This is borrowed (almost unmodified) from GNU grep to provide faster searches.
|
|
|
|
eval.c
|
|
|
|
Node_var, Node_var_array and Node_param_list handled from macro rather
|
|
than in r_tree_eval().
|
|
Changed cmp_nodes() to not do a force_number() -- this, combined with a
|
|
force_number() on ARGV[] and ENVIRON[] brings it into line with other awks
|
|
Greatly simplified cmp_nodes().
|
|
Separated out Node_NF, Node_FS, Node_RS, Node_NR and Node_FNR in get_lhs().
|
|
All adjacent string concatenations now done at once.
|
|
|
|
field.c
|
|
|
|
Added support for FIELDWIDTHS.
|
|
Fixed bug in get_field() whereby changes to a field were not always
|
|
properly reflected in $0.
|
|
Reordered tests in parse_field() so that reference off the end of the buffer
|
|
doesn't happen.
|
|
set_FS() now sets *parse_field i.e. routine to call depending on type of FS.
|
|
It also does make_regexp() for FS if needed. get_field() passes FS_regexp
|
|
to re_parse_field(), as does do_split().
|
|
Changes to set_field() and set_record() to avoid malloc'ing and free'ing the
|
|
field nodes repeatedly. The fields now just point into $0 unless they are
|
|
assigned to another variable or changed. force_number() on the field is
|
|
*only* done when the field is needed.
|
|
|
|
gawk.1
|
|
|
|
Fixed troff formatting problem on .TP lines.
|
|
|
|
io.c
|
|
|
|
Moved some code out into iop.c.
|
|
Output from pipes and system() calls is properly synchronized.
|
|
Status from pipe close properly returned.
|
|
Bug in getline with no redirect fixed.
|
|
|
|
iop.c
|
|
|
|
This file contains a totally revamped get_a_record and associated code.
|
|
|
|
main.c
|
|
|
|
Command line programs no longer use a temporary file.
|
|
Therefore, tmpnam() no longer required.
|
|
Deprecated -a and -e options -- they will go away in the next release,
|
|
but for now they cause a warning.
|
|
Moved -C, -V, -c options to -W ala posix.
|
|
Added -W posix option: throw out \x
|
|
Added -W lint option.
|
|
|
|
|
|
node.c
|
|
|
|
force_number() now allows pure numerics to have leading whitespace.
|
|
Added make_string facility to optimize case of adding an already malloc'd
|
|
string.
|
|
Cleaned up and simplified do_deref().
|
|
Fixed bug in handling of stref==255 in do_deref().
|
|
|
|
re.c
|
|
|
|
contains the interface to regexp code
|
|
|
|
Changes from 2.11.1 to FSF version of same
|
|
------------------------------------------
|
|
Thu Jan 4 14:19:30 1990 Jim Kingdon (kingdon at albert)
|
|
|
|
* Makefile (YACC): Add -y to bison part.
|
|
|
|
* missing.c: Add #include <stdio.h>.
|
|
|
|
Sun Dec 24 16:16:05 1989 David J. MacKenzie (djm at hobbes.ai.mit.edu)
|
|
|
|
* Makefile: Add (commented out) default defines for Sony News.
|
|
|
|
* awk.h: Move declaration of vprintf so it will compile when
|
|
-DVPRINTF_MISSING is defined.
|
|
|
|
Mon Nov 13 18:54:08 1989 Robert J. Chassell (bob at apple-gunkies.ai.mit.edu)
|
|
|
|
* gawk.texinfo: changed @-commands that are not part of the
|
|
standard, currently released texinfmt.el to those that are.
|
|
Otherwise, only people with the as-yet unreleased makeinfo.c can
|
|
format this file.
|
|
|
|
Changes from 2.11beta to 2.11.1 (production)
|
|
--------------------------------------------
|
|
|
|
Went from "beta" to production status!!!
|
|
|
|
Now flushes stdout before closing pipes or redirected files to
|
|
synchronize output.
|
|
|
|
MS-DOS changes added in.
|
|
|
|
Signal handler return type parameterized in Makefile and awk.h and
|
|
some lint removed. debug.c cleaned up.
|
|
|
|
Fixed FS splitting to never match null strings, per book.
|
|
|
|
Correction to the manual's description of FS.
|
|
|
|
Some compilers break on char *foo = "string" + 4 so fixed version.sh and
|
|
main.c.
|
|
|
|
Changes from 2.10beta to 2.11beta
|
|
---------------------------------
|
|
|
|
This release fixes all reported bugs that we could reproduce. Probably
|
|
some of the changes are not documented here.
|
|
|
|
The next release will probably not be a beta release!
|
|
|
|
The most important change is the addition of the -nostalgia option. :-)
|
|
|
|
The documentation has been improved and brought up-to-date.
|
|
|
|
There has been a lot of general cleaning up of the code that is not otherwise
|
|
documented here. There has been a movement toward using standard-conforming
|
|
library routines and providing them (in missing.d) for systems lacking them.
|
|
Improved (hopefully) configuration through Makfile modifications and missing.c.
|
|
In particular, straightened out confusion over vprintf #defines, declarations
|
|
etc.
|
|
|
|
Deleted RCS log comments from source, to reduce source size by about one third.
|
|
Most of them were horribly out-of-date, anyway.
|
|
|
|
Renamed source files to reflect (for the most part) their contents.
|
|
|
|
More and improved error messages. Cleanup and fixes to yyerror().
|
|
String constants are not altered in input buffer, so error messages come out
|
|
better. Fixed usage message. Make use of ANSI C strerror() function
|
|
(provided).
|
|
|
|
Plugged many more memory leaks. The memory consumption is now quite
|
|
reasonable over a wide range of programs.
|
|
|
|
Uses volatile declaration if STDC > 0 to avoid problems due to longjmp.
|
|
|
|
New -a and -e options to use awk or egrep style regexps, respectively,
|
|
since POSIX says awk should use egrep regexps. Default is -a.
|
|
|
|
Added -v option for setting variables before the first file is encountered.
|
|
Version information now uses -V and copyleft uses -C.
|
|
|
|
Added a patchlevel.h file and its use for -V and -C.
|
|
|
|
Append_right() optimized for major improvement to programs with a *lot*
|
|
of statements.
|
|
|
|
Operator precedence has been corrected to match draft Posix.
|
|
|
|
Tightened up grammar for builtin functions so that only length
|
|
may be called without arguments or parentheses.
|
|
|
|
/regex/ is now a normal expression that can appear in any expression
|
|
context.
|
|
|
|
Allow /= to begin a regexp. Allow ..[../..].. in a regexp.
|
|
|
|
Allow empty compound statements ({}).
|
|
|
|
Made return and next illegal outside a function and in BEGIN/END respectively.
|
|
|
|
Division by zero is now illegal and causes a fatal error.
|
|
|
|
Fixed exponentiation so that x ^ 0 and x ^= 0 both return 1.
|
|
|
|
Fixed do_sqrt, do_log, and do_exp to do argument/return checking and
|
|
print an error message, per the manual.
|
|
|
|
Fixed main to catch SIGSEGV to get source and data file line numbers.
|
|
|
|
Fixed yyerror to print the ^ at the beginning of the bad token, not the end.
|
|
|
|
Fix to substr() builtin: it was failing if the arguments
|
|
weren't already strings.
|
|
|
|
Added new node value flag NUMERIC to indicate that a variable is
|
|
purely a number as opposed to type NUM which indicates that
|
|
the node's numeric value is valid. This is set in make_number(),
|
|
tmp_number and r_force_number() when appropriate and used in
|
|
cmp_nodes(). This fixed a bug in comparison of variables that had
|
|
numeric prefixes. The new code uses strtod() and eliminates is_a_number().
|
|
A simple strtod() is provided for systems lacking one. It does no
|
|
overflow checking, so could be improved.
|
|
|
|
Simplification and efficiency improvement in force_string.
|
|
|
|
Added performance tweak in r_force_number().
|
|
|
|
Fixed a bug with nested loops and break/continue in functions.
|
|
|
|
Fixed inconsistency in handling of empty fields when $0 has to be rebuilt.
|
|
Happens to simplify rebuild_record().
|
|
|
|
Cleaned up the code associated with opening a pipe for reading. Gawk
|
|
now has its own popen routine (gawk_popen) that allocates an IOBUF
|
|
and keeps track of the pid of the child process. gawk_pclose
|
|
marks the appropriate child as defunct in the right struct redirect.
|
|
|
|
Cleaned up and fixed close_redir().
|
|
|
|
Fixed an obscure bug to do with redirection. Intermingled ">" and ">>"
|
|
redirects did not output in a predictable order.
|
|
|
|
Improved handling of output buffering: now all print[f]s redirected to a tty
|
|
or pipe are flushed immediately and non-redirected output to a tty is flushed
|
|
before the next input record is read.
|
|
|
|
Fixed a bug in get_a_record() where bcopy() could have copied over
|
|
a random pointer.
|
|
|
|
Fixed a bug when RS="" and records separated by multiple blank lines.
|
|
|
|
Got rid of SLOWIO code which was out-of-date anyway.
|
|
|
|
Fix in get_field() for case where $0 is changed and then $(n) are
|
|
changed and then $0 is used.
|
|
|
|
Fixed infinite loop on failure to open file for reading from getline.
|
|
Now handles redirect file open failures properly.
|
|
|
|
Filenames such as /dev/stdin now allowed on the command line as well as
|
|
in redirects.
|
|
|
|
Fixed so that gawk '$1' where $1 is a zero tests false.
|
|
|
|
Fixed parsing so that `RLENGTH -1' parses the same as `RLENGTH - 1',
|
|
for example.
|
|
|
|
The return from a user-defined function now defaults to the Null node.
|
|
This fixes a core-dump-causing bug when the return value of a function
|
|
is used and that function returns no value.
|
|
|
|
Now catches floating point exceptions to avoid core dumps.
|
|
|
|
Bug fix for deleting elements of an array -- under some conditions, it was
|
|
deleting more than one element at a time.
|
|
|
|
Fix in AWKPATH code for running off the end of the string.
|
|
|
|
Fixed handling of precision in *printf calls. %0.2d now works properly,
|
|
as does %c. [s]printf now recognizes %i and %X.
|
|
|
|
Fixed a bug in printing of very large (>240) strings.
|
|
|
|
Cleaned up erroneous behaviour for RS == "".
|
|
|
|
Added IGNORECASE support to index().
|
|
|
|
Simplified and fixed newnode/freenode.
|
|
|
|
Fixed reference to $(anything) in a BEGIN block.
|
|
|
|
Eliminated use of USG rand48().
|
|
|
|
Bug fix in force_string for machines with 16-bit ints.
|
|
|
|
Replaced use of mktemp() with tmpnam() and provided a partial implementation of
|
|
the latter for systems that don't have it.
|
|
|
|
Added a portability check for includes in io.c.
|
|
|
|
Minor portability fix in alloc.c plus addition of xmalloc().
|
|
|
|
Portability fix: on UMAX4.2, st_blksize is zero for a pipe, thus breaking
|
|
iop_alloc() -- fixed.
|
|
|
|
Workaround for compiler bug on Sun386i in do_sprintf.
|
|
|
|
More and improved prototypes in awk.h.
|
|
|
|
Consolidated C escape parsing code into one place.
|
|
|
|
strict flag is now turned on only when invoked with compatability option.
|
|
It now applies to fewer things.
|
|
|
|
Changed cast of f._ptr in vprintf.c from (unsigned char *) to (char *).
|
|
Hopefully this is right for the systems that use this code (I don't).
|
|
|
|
Support for pipes under MSDOS added.
|
