872
similar to what we already do for strings.
873

888
both regular and MPFR.
889
(format_tree): Use them in out of range calculation. Check for out
890
of range in floating point formats also. Allow new *undocumented*

904
* node.c (r_force_number): If strtod returns ERANGE, accept the
905
value as being numeric instead of forcing it to zero. The impact
906

907
be converted to inf or -inf instead of 0. Thanks to Daniel
908
Pettet for reporting this issue.

1463
[@namespace]: Don't YYABORT on bad namespace so that we can check
1464
the rest of the program.
1465
(validate_qualified_name): Check traditional / posix first. Return
1466
after printing an error message; we don't want to print multiple
1467
messages for the same identifer.
1468

bad identifier, call validate_qualified_name and instead of
1480
check_special use check_qualified_name.
1481
1482
2017-07-17 Arnold D. Robbins <arnold@skeeve.com>
1483
1484
Allow identifiers that are gawk extensions to be used as plain
1485
identifiers outside the "awk" namespace. Make the real

1490
or not.
1491

(getfname): Add boolean parameter to prepend namespace
1496

LEX_LENGTH expansions.
1514

1515

1517

1518
conflict, and those are bad. I don't know why I didn't
1519
notice this earlier. Sigh.

* gawkapi.h (awk_input_buf_t): Remove field_width array and instead
2113
add it as a 6th argument to the get_record function. This should
2114
not break existing code, since it's fine to ignore the additional
2115
argument. Document the behavior of the field_width argument.
2116

2117
and then hand it off to set_record.

2153
3rd argument to enable API field parsing overrides.

* main.c (load_procinfo): Use new current_field_sep_str function
2156
instead of switching on the return value from current_field_sep.

2253
from string overrun.
2254
(do_dcngettext): Need to terminate string1 and string2 also,
2255
and replace strlen(the_result), which could overrun.
2256
(do_bindtextdomain): Terminate both string args, and eliminate

2271
* node.c (is_hex): Add a new argument pointing to the end of the string
2272
so we can check for string overrun.

* awk.h (get_numbase): Add string length argument so we can operate
2278
on unterminated strings.
2279

error in length passed to nondec2awknum: should be strlen(tokstart)-1
2281
based on surrounding code.
2282

2291
to terminate it in case it's a field variable.
2292
2293
2017-01-26 Andrew J. Schorr <aschorr@telemetry-investments.com>
2294

2017-01-26 Andrew J. Schorr <aschorr@telemetry-investments.com>
2303
2304
* awk.h (enum block_id): Remove BLOCK_INVALID, since it serves no
2305
useful purpose and seems to slow things down a bit.
2306
* node.c (nextfree): Remove first invalid entry.
2307
2308
2017-01-25 Andrew J. Schorr <aschorr@telemetry-investments.com>
2309
2310
* awk.h (BLOCK): Remove typedef. BLOCK was used for 2 different
2311
purposes: to contain a block allocation list header, and to hold
2312
each individual allocated item. This was confusing, because the "size"
2313
field was set only in the header, but not in each element.
2314
(struct block_header): The block header contains a pointer to the first
2315
element and the element size.
2316
(struct block_item): Represent a single allocated item. This contains
2317
only a pointer to the next element. This reduces the minimum allocated
2318
item size from 2 pointers to 1 (16 bytes to 8 bytes on x86_64).
2319
(nextfree): Change array item type from BLOCK to struct block_header.
2320
(getblock, freeblock): Change cast from 'BLOCK' to 'struct block_item'.
2321
* node.c (nextfree): Now an array of 'struct block_header' instead of
2322
BLOCK. Switch the ordering to put the next pointer before the size.
2323
(more_blocks): Replace 'BLOCK' with 'struct block_item', and add
2324
an assert to ensure that the allocation size is at least as large
2325
as 'struct block_item', i.e. 1 pointer.
2326
2327
2017-01-22 Andrew J. Schorr <aschorr@telemetry-investments.com>
2328
2329
* awk.h (numtype_choose): New backend macro used to implement
2330
various macros whose calculations depend on how a number is
2331
actually represented. This improves readability and should give
2332
a small performance improvement when not using extended precision.
2333
(get_number_ui, get_number_si, get_number_d, get_number_uj, iszero):
2334
Rewrite using new numtype_choose macro.
2335
2336
2017-01-04 Arnold Robbins <arnold@skeeve.com>
2337
2338
Trade space for time for programs that toggle IGNORECASE a lot.
2339
Brings 25% to 39% speedup. NODE does not actually grow in size.
2340
2341
* awk.h (NODE::preg): Now an array of size two.
2342
[CASE]: Flag no longer needed, so removed.
2343
(IGNORECASE): Change type from int to bool.
2344
* awkgram.y (make_regnode): Build two copies of the compiled regexp,
2345
one without ignorecase, and one with.
2346
* io.c (RS_re): Array replacing RS_re_yes_case and RS_re_no_case.
2347
(set_RS): Use RS_re[IGNORECASE] as appropriate. Free and recompute
2348
as needed.
2349
* main.c (IGNORECASE): Change type from int to bool.
2350
* re.c (re_update): Simplify the code. No need to check CASE flag
2351
any longer. Recompute only if text of regexp changed.
2352
* symbol.c (free_bc_internal): Adjust to free both elements of
2353
m_re_reg.
2354
2355
2017-01-18 Andrew J. Schorr <aschorr@telemetry-investments.com>
2356
2357
* interpret.h (r_interpret): Increase robustness of the optimization
2358
logic in Op_assign_concat -- check that the node has MALLOC set,
2359
and make sure to wipe all flags other than MALLOC, STRING, STRCUR,
2360
and possibly WSTRCUR. Use STFMT_UNUSED define.
2361
2362
2017-01-15 Andrew J. Schorr <aschorr@telemetry-investments.com>
2363
2364
* interpret.h (r_interpret): Fix bug in Op_assign_concat reported
2365
on Cygwin mailing list. The string concatenation optimization was
2366
not updating the node correctly by setting STRING and STRCUR flags
2367
and setting stfmt.

2393
allocate and free memory blocks for extended-precision math.

2397
an awk_value_t.

2403
to reduce code duplication.
2404
(nextfree): Add block allocators for mpfr_t and mpz_t.
2405
(more_blocks): Add an assert to protect against cases where the block
2406
size is too small to hold our structure.
2407

Put min second, which preserves source code compatibility.

2520
should return false, as per the header file documentation.

true, we have serious bugs.
2546
* builtin.c (do_typeof): Do not treat Node_var the same way as
2547
Node_val, since they are different beasts. In reality, the argument

* re.c (make_regexp): Only call dfasyntax if actually using

* awk.h: Add a comment explaining the NUMINT flag in more detail.
2933
* int_array.c (standard_integer_string): New function to test whether
2934
a string matches what would be produced by sprintf("%ld", <value>).
2935
(is_integer): Fix bug -- if NUMBER was set, then the function was
2936
accepting strnum values with nonstandard string representations. We
2937
now call standard_integer_string to check that the string looks OK.
2938
Also added ifdef'ed code to simplify the function by relying upon
2939
force_number to parse the string, but this is disabled due to possible
2940
negative performance impact.

2977
(init_mpfr, set_PREC): Save mpfr_set_default_prec argument in
2978
default_prec.
2979
(do_mpfr_func): If the argument's precision exceeds the default
2980
precision, boost the result's precision to match it. This fixes a
2981
bug where we used to copy the argument's precision, regardless of
2982
whether it was higher or lower than the PREC setting.

2986
* re.c (research): Now that the dfa matcher correctly runs even
2987
in multibyte locales, try it if even if need_start is true.
2988
However, if start > 0, avoid dfa matcher, since it can't handle
2989
the case where the search starts in the middle of a string.

textdomain to here; they must be done after calling setlocale.

3049
3050
* awk.h: Restore previous comment about unterminated strings, since
3051
I am removing the string termination patches from field.c
3052
(free_api_string_copies): Declare new gawkapi function.
3053
* builtin.c (do_mktime, do_system): Restore temporary string
3054
termination to protect against unterminated field values.
3055
(nondec2awknum): Remove comment about unnecessary termination.
3056
* eval.c (posix_compare): Restore temporary string termination.
3057
* field.c (databuf): Remove struct, no longer needed.
3058
(set_field): Remove memcpy for string termination, since we will support
3059
unterminated field string values.
3060
(rebuild_record): Ditto. Also no need to allocate space for terminated
3061
string copies.
3062
(allocate_databuf): Remove function, since memory management can again
3063
be done inside set_record.
3064
(set_record): Restore inline buffer management logic.
3065
(reset_record): Remove calls to allocate_databuf, since we no longer
3066
need space for making terminated copies of field strings.
3067
* gawkapi.c (free_api_string_copies): New function to free strings
3068
that we made to provide terminated copies to API functions.
3069
(assign_string): New function to convert a string to an awk_value,
3070
making sure to copy it if we need to terminate it.
3071
(node_to_awk_value): Use assign_string to return string values with
3072
NUL termination protection.
3073
* int_array.c (is_integer): Restore temporary string termination.
3074
* interpret.h (Op_push_i): Ditto.

3076
free_api_string_copies to free temporary string copies.

3078
* node.c (r_force_number, get_ieee_magic_val): Ditto.
3079
3080

by earlier changes in the fixtype branch.)
3088
3089
2016-07-06 Andrew J. Schorr <aschorr@telemetry-investments.com>
3090
3091
* awk.h: Modify comments to indicate that MAYBE_NUM will now be
3092
left enabled to indicate strnum values by the NUMBER|MAYBE_NUM
3093
combination, whereas STRING|MAYBE_NUM indicates a potential strnum.
3094
(fixtype): Modify MAYBE_NUM test to avoid calling force_number if
3095
NUMCUR is already set.
3096
* builtin.c (do_typeof): Call fixtype to resolve argument type.
3097
This forces parsing of numeric strings, so there's a performance
3098
penalty, but we must do this to give a correct result. The meaning
3099
of "strnum" changes from "potential strnum" to "actual strnum".
3100
* eval.c (set_TEXTDOMAIN): Remove some dead code left over from last
3101
patch.
3102
* int_array.c (is_integer): When a MAYBE_NUM is converted successfully
3103
to a NUMBER, leave the MAYBE_NUM flag enabled.
3104
* mpfr.c (mpg_force_number): Ditto.
3105
* node.c (r_force_number): Ditto.
3106
3107
2016-07-06 Andrew J. Schorr <aschorr@telemetry-investments.com>
3108
3109
* awk.h: Modify stptr comment to indicate that all strings are now
3110
NUL-terminated.
3111
* builtin.c (do_mktime): Remove unnecessary logic to terminate
3112
the string with '\0' temporarily.
3113
(do_system) Ditto.
3114
(nondec2awknum): Add a comment about termination.
3115
* eval.c (posix_compare): Remove logic to terminate strings temporarily.
3116
(set_ORS): No need to terminate ORS, since the string node is already
3117
terminated. What gave us the right to modify that node anyway?
3118
(fmt_index): Remove code to terminate string. This seems to have been
3119
invalid anyway, since we don't own that memory.
3120
(set_TEXTDOMAIN): Do not terminate TEXTDOMAIN string, since the node
3121
is already terminated. We didn't have the right to modify that node
3122
anyway.
3123
* gawkapi.c (node_to_awk_value): Add assert checks to confirm that the
3124
string is NUL-terminated.
3125
* gawkapi.h: Modify awk_string comment to indicate that strings are
3126
always terminated with '\0'.
3127
* int_array.c (isinteger): Remove unnecessary logic to terminate string
3128
with '\0' temporarily.
3129
* interpret.h (Op_push_i): Ditto.
3130
* io.c (nextfile): Remove string termination. We didn't own that memory
3131
anyway.
3132
* mpfr.c (force_mpnum): Remove unnecessary logic to terminate the
3133
string with '\0' temporarily.
3134
* node.c (r_force_number): Remove NUL termination around strtod call,
3135
since we already know that there is either a white space or '\0'
3136
character there. Either one will stop strtod.
3137
(get_ieee_magic_val): Ditto.
3138
* profile.c (pp_number): No need to terminate string returned by
3139
r_format_val.
3140
3141
2016-07-06 Andrew J. Schorr <aschorr@telemetry-investments.com>
3142
3143
* interpret.h (Op_field_spec): Now that all $n field values are
3144
NUL-terminated, there is no reason to call dupnode for $n where n > 0.
3145
This saves malloc and copying overhead, thereby more than offsetting the
3146
performance hit of the additional copying and NUL-termination in the
3147
last patch to field.c. It also eliminates repeated parsing in cases
3148
where $n, for n > 1, was accessed more than once in a numeric context,
3149
so the new approach should be a performance win.
3150
3151
2016-07-06 Andrew J. Schorr <aschorr@telemetry-investments.com>
3152
3153
Make sure that all field values, and therefore all strings inside gawk,
3154
are terminated with a '\0' character!
3155
3156
* field.c (databuf): New static struct to hold info about our buffer to
3157
contain the field string values.
3158
(allocate_databuf): New function to make sure the databuf is large
3159
enough to hold $0 and copies of $1 through $NF.
3160
(set_field): Copy $n into free space previously allocated in databuf
3161
and add a '\0' at the end.
3162
(rebuild_record): Call allocate_databuf to ensure sufficient space
3163
for copying non-malloced field values. When copying field values,
3164
use databuf to create a NUL-terminated copy.
3165
(purge_record): New function extracted from reset_record to initialize
3166
$1 through $NF to null values.
3167
(set_record): Buffer management moved to new allocate_databuf function.
3168
Call purge_record instead of reset_record, since reset_record contains
3169
some extra logic not needed in this case.
3170
(reset_record): Call purge_record to do most of the work, and call
3171
allocate_databuf to make sure we have a big enough buffer to contain
3172
copies of the $1 through $NF.
3173

3189
3190
* awk.h (FIELD): Remove unnecessary flag.
3191
(MALLOC): Move definition to join the others, and improve the comment.
3192
* array.c (value_info): Replace FIELD test with MALLOC test.
3193
* eval.c (flags2str): Remove FIELD flag.
3194
* field.c (init_fields): Remove FIELD bit from Null_field->flags.
3195
(set_field): Remove FIELD bit from flags.
3196
(rebuild_record): Test against MALLOC instead of FIELD. If a field
3197
node has valref > 1, we should make a copy, although I don't think
3198
it is valid for this to happen.
3199
(set_record): Remove FIELD bit from flags.
3200
* interpret.h (UNFIELD): Add comment, and test MALLOC flag instead of
3201
FIELD. Remove probably buggy code to disable the FIELD flag when
3202
valref is 1; that would have created a node where neither the FIELD
3203
nor MALLOC flag was set, which seems invalid.
3204
* node.c (r_dupnode): Remove code disabling FIELD flag.
3205
3206
2016-07-04 Andrew J. Schorr <aschorr@telemetry-investments.com>
3207
3208

3210
(force_string): Reimplement as a macro using force_string_fmt function.
3211
(force_string_ofmt): New macro to get a value's OFMT representation.
3212
* builtin.c (do_print): Use new force_string_ofmt macro instead of
3213
duplicating the logic inline.
3214
3215
2016-07-04 Andrew J. Schorr <aschorr@telemetry-investments.com>
3216
3217
* str_array.c (str_lookup): There is no need to worry about the
3218
MAYBE_NUM flag, since the code has been patched to make sure to
3219
preserve the string value of strnum values, and the integer array
3220
code should no longer mistakenly claim a strnum integer with a
3221
nonstandard string representation.

3229
2016-07-03 Andrew J. Schorr <aschorr@telemetry-investments.com>
3230

* node.c (r_format_val): Do not free stptr unless STRCUR is set.
3295
This is safer than testing for non-NULL stptr, since, for example,

3313
* builtin.c (do_print): Do not use OFMT to print strnum values. We
3314
accomplish this by calling format_val for a NUMBER only
3315
if there is no string currently available, or if stfmt equals
3316
neither -1 nor OFMTidx.

2016-06-14 Andrew J. Schorr <aschorr@telemetry-investments.com>
3384
3385
* gawkapi.c (node_to_awk_value): When caller requests AWK_SCALAR
3386
or AWK_UNDEFINED, we need to call fixtype before we check the type.
3387
3388
2016-06-13 Andrew J. Schorr <aschorr@telemetry-investments.com>
3389
3390

3398
* array.c (sort_up_value_type): Call fixtype before checking the value
3399
types.
3400
* awkgram.y (yylex): Pass NULL endptr argument to nondec2awknum.
3401
(valinfo): Remove dead tests: either STRING or NUMBER or both
3402
must be set, so there's no reason to continue with checks for NUMCUR or
3403
STRCUR.
3404
* builtin.c (do_exp, do_int, do_log, do_sqrt, do_sin, do_cos, do_srand):
3405
Fix lint check for non-numeric argument.
3406
(do_string): Fix lint check for 1st and 2nd args being strings.
3407
(do_length): Fix assert to allow for Node_typedregex.
3408
Fix lint check for non-string argument.
3409
(format_tree): Fix type detection for '%c' arguments.
3410
(do_strftime): Fix lint check for non-numeric 2nd argument and
3411
lint check for non-string 1st argument.
3412
(do_mktime): Fix lint check for non-string argument. Eliminate useless
3413
logic to save and restore terminating NUL.
3414
(do_system, do_tolower, do_toupper): Fix lint check for non-string
3415
argument.
3416
(do_atan2, do_lshift, do_rshift, do_and, do_or, do_xor, do_compl,
3417
do_intdiv): Fix lint checks for non-numeric args.
3418
(do_sub): Attempt to clean up treatment of 3rd argument to gensub
3419
despite vague documentation of expected behavior.
3420
(do_strnum): Fix bug in number detection logic, and pass new endptr
3421
arg to nondec2awknum.
3422
(nondec2awknum): Add endptr argument so caller can detect how much
3423
of the string was consumed. Eliminate unnecessary logic to save
3424
and restore terminating NUL char.
3425
(do_typeof): Use a switch to specify which cases are supported, and
3426
issue a warning message when a corrupt type is detected.
3427
* debug.c (print_memory): At least one of NUMBER and STRING should
3428
be set, so no need to check for NUMCUR or STRCUR in addition.
3429
* eval.c (cmp_nodes): Use fixtype function to fix arg types.
3430
(set_IGNORECASE): Fix logic for acting on value type. Note that
3431
setting IGNORECASE to a string value of "0" with NUMCUR set now enables
3432
ignorecase, so that's a subtle change in behavior that seems to match
3433
the docs.
3434
(set_LINT): Try to clean up configuration logic based on type.
3435
* ext.c (get_argument): Remove unused variable pcount.
3436
* gawkapi.c (node_to_awk_value): Remove pointless test for NUMCUR
3437
after calling force_number. Similarly, no need to test for STRCUR
3438
after calling force_string.
3439
* int_array.c (is_integer): Reject cases where a string value is
3440
present that will not be correctly regenerated from the integer;
3441
in particular, this could happen where blank space padding is present,
3442
leading zeroes are present, or for hex or octal values.
3443
Also fix some bugs where a strnum was converted to a NUMBER without
3444
turning off the STRING bit.
3445
* io.c (redirect_string): Make lint warning message more accurate.
3446
(redirect): Change not_string test to use STRING bit, not STRCUR.
3447
(pty_vs_pipe): Use fixtype to correct logic for detecting whether a
3448
value is anumber.
3449
* mpfr.c (mpg_force_number): If NUMCUR is set, there's no need to
3450
test is_mpg_number. If it's not, the NODE is corrupt and we've got
3451
bigger problems. Fix flag manipulation logic. Always set NUMCUR and
3452
clear MAYBE_NUM,
3453
(set_PREC): Fix logic using fixtype function.
3454
(do_mpfr_atan2, do_mpfr_intdiv): Fix lint check for non-numeric
3455
arguments.
3456
(do_mpfr_func, do_mpfr_int, do_mpfr_compl, get_intval, do_mpfr_srand):
3457
Fix lint check for non-numeric argument.
3458
(do_mpfr_strtonum): Use fixtype and stop testing for NUMCUR bit.
3459
* node.c (r_force_number): Eliminate pointless save and restore of
3460
terminating NUL char. Always set NUMCUR and clear MAYBE_NUM, and
3461
convert STRING to NUMBER if appropriate, fixing bugs in flag
3462
manipulations. For non-decimal data, need to consider whether there
3463
is trailing non-numeric data in deciding whether a MAYBE_NUM should
3464
be converted to a NUMBER, so take advantage of new endptr arg
3465
to nondec2awknum.

3553
3554
* awk.h (get_actual_argument): Add an initial argument containing

add an initial node argument to pass through to get_actual_argument.

3561
avoid repeating the call to get_argument. We can also eliminate the

* builtin.c (format_tree): After the string has been rendered, use
3604

3714
Considerable improvements to handling of comments when pretty
3715
printing, particularly for end-of-line comments.
3716
3717
* awkgram.y (prior_comment, comment_to_save): New variables.
3718
(add_pending_comment): New function.
3719
(grammar): Jump through lots more hoops to capture comments.
3720
Due to shift-reduce parsing, there can be up to two comments
3721
captured and waiting to be saved; be sure to get them both and
3722
at the right times. This is difficult since comments have no
3723
real syntactic existence. Call add_pending_comment on most of
3724
the simple statements.
3725
(get_comment): Save a pre-existing comment in prior_comment.
3726
(split_comment): Use comment_to_save instead of `comment'.
3727
* profile.c (end_line): Change to return the instruction after
3728
the comment that gets printed; adjust return type.
3729
(pprint): Add skip_comment static variable. Adjust logic for
3730
skipping an end-of-line comment; only do it if skip_comment is
3731
true. This is set to true in places where we can't use the
3732
return value from end_line(). Call end_line() in many more places.
3733
(pp_func): Handle end-of-line comments after a function header.
3734
3735
2016-03-17 Arnold D. Robbins <arnold@skeeve.com>
3736
3737
* debug.c (print_instruction): For Op_comment, improve notation as
3738
to whether it's a full comment or an end of line comment.
3739
3740
2016-03-14 Arnold D. Robbins <arnold@skeeve.com>
3741
3742
* io.c (socketopen): For SOCK_DGRAM, set read_len to sizeof
3743
remote_addr. Makes UDP more or less work again.
3744
Thanks to Juergen Kahrs for the fix.
3745
3746
2016-03-11 Arnold D. Robbins <arnold@skeeve.com>

3763
3764
2016-03-07 Arnold D. Robbins <arnold@skeeve.com>

3767

3768
* builtin.c (do_system): Augment the logic for the return
3769
value so that death-by-signal info is available too.
3770
3771
2016-03-03 Arnold D. Robbins <arnold@skeeve.com>

4061

4063
* awk.h: Allow <strings.h> to be #included together with

<string.h> as this is required on some systems (z/OS).
4065
* io.c, configure.ac: <sys/select.h> is needed for select()

4068
more elegant/general way.
4069
* awkgram.y, command.y, configure.ac, eval.c,
4070
helpers/testdfa.c: Define and use the USE_EBCDIC cpp symbol
4071
instead of checking the value of 'a' whenever we want to know
4072
if we're on an EBCDIC system. Also, don't assume that z/OS
4073
necessarily means EBCDIC, as the compiler does have an ASCII
4074
mode (-qascii).
4075
* awkgram.y, command.y, configure.ac: On EBCDIC systems,
4076
convert singleton EBCDIC characters in the input stream to
4077
ASCII on the fly so that the generated awkgram.c/command.c in
4078
the distributed sources can be used, i.e. we don't have to
4079
require the user to build Bison and re-generate those files
4080
themselves. This implementation uses a z/OS-specific function
4081
(__etoa_l()) to do the conversion, but support for other
4082
systems can be added in the future as necessary.
4083
* io.c: No need to protect this block of "#if
4084
defined(HAVE_TERMIOS_H)" code from z/OS; it works just fine
4085
there.
4086
* configure.ac: Check for the "struct passwd.pw_passwd" and
4087
"struct group.gr_passwd" fields and conditionalize their use,
4088
as they don't exist on z/OS. Needed for doc/gawktexi.in.

4583
a new terminal (HARD_REGEX).
4584

4586
assignment and as an argument in function call. New set of nonterminals

4606
the error from getaddrinfo() up to the caller. Add explanatory
4607
comments.

4616
* io.c (socketopen): New parameter hard_error; set it if
4617
getaddrinfo() fails. Change fatals to warnings.
4618
(devopen): Pass in address of boolean hard_error variable
4619
and stop trying to open the file if hard_error is true.
4620
Save and restore errno around call to socketopen() and
4621
use restored errno if open() fails at strictopen.

4700
2015-02-05 Andrew J. Schorr <aschorr@telemetry-investments.com>
4701
4702

* awkgram.y (variable_create): Remove function.
4785
(variable): Restore variable_create functionality inline.

deferred variable check should be done when lookup is called, not here.
4788
4789
2015-01-07 Andrew J. Schorr <aschorr@telemetry-investments.com>
4790
4791
* gawkapi.c (api_set_array_element): Remove stray call to
4792
make_aname. I cannot see what purpose this served. Maybe I am
4793
missing something.
4794
4795
2015-01-07 Arnold D. Robbins <arnold@skeeve.com>

Load deferred variables if extensions are used; they might
4806
want to access PROCINFO and/or ENVIRON. Thanks to Andrew Schorr
4807
for pointing out the issue.
4808
4809
* awkgram.y (extensions_used): New variable. Set it on @load.
4810

4813
2015-01-06 Andrew J. Schorr <aschorr@telemetry-investments.com>
4814
4815
* gawkapi.c (api_sym_update): If copying a subarray, must update
4816
the parent_array pointer. Also, call the astore hook if non-NULL.
4817
(api_set_array_element): Call the astore hook if non-NULL.
4818
4819
2015-01-06 Andrew J. Schorr <aschorr@telemetry-investments.com>
4820
4821
* awk.h (variable_create): Now takes a 3rd argument to tell caller
4822
whether this is a deferred variable.
4823
* awkgram.y (variable_create): Return indicator of whether this is
4824
a deferred variable in a newly added 3rd arg.
4825
(variable): Pass 3rd arg to variable_create.
4826
* gawkapi.c (api_sym_update): If we triggered the creation of a deferred
4827
variable, we must merge the extension's array elements into the deferred
4828
array, not the other way around. The ENVIRON array has special funcs
4829
to call setenv and unsetenv.

* gawkapi.c (api_sym_update): If an array is being created, then
4839
call new function variable_create instead of install_symbol. If this
4840
is the first reference to a deferred variable, than the new array
4841
may contain elements that must be merged into the array provided by
4842
the extension.

4844
2015-01-05 Andrew J. Schorr <aschorr@telemetry-investments.com>
4845
4846
* io.c (wait_any): If the `interesting' argument is non-zero, then we
4847
must not return until that child process has exited, since the caller
4848
gawk_pclose depends on our returning its exit status. So in that case,
4849
do not pass WNOHANG to waitpid.

Make sane the handling of AWKPATH and AWKLIBPATH:
5118
5119
1. Don't explicitly search "."; it must be in the path either
5120
physically or as null element a la the shell's $PATH
5121
2. If environment's value was empty, use built-in default value.
5122
3. Set ENVIRON["AWK*PATH"] to the path used.
5123
5124
* io.c (path_info): Remove try_cwd member.
5125
(get_cwd): Removed, not needed anymore.

* configure.ac (AC_CHECK_FUNCS): Add a check for waitpid.
6248
* io.c (wait_any): Enhance comment to explain why we loop reaping all
6249
exited children when the argument is zero. When available, use waitpid
6250
with WNOHANG to avoid blocking. Remove my previous incorrect patch to
6251
exit after reaping the first child. The function is intended to

6267
* gawkapi.c (api_get_file): After nextfile starts a new file,
6268
we need to run the BEGINFILE actions. We retrieve the
6269
instruction pointer from main_beginfile and execute it until
6270

6276
element index will always be a string!
6277
* gawkapi.c (api_flatten_array): When converting the index to an awk
6278
value, request a string conversion, since we want the indices to
6279
appear as strings to the extensions. This makes the call to
6280
force_string redundant, since node_to_awk_value does that internally
6281
when we request a string.

* io.c (inrec): Since get_a_record may now return -2, be sure
6287
to throw an error in that case as well.
6288
(wait_any): Fix what appears to be a bug. The old logic repeatedly
6289
called wait until it failed. When a process has multiple children,
6290
this causes it to stall until all of them have exited. Instead,
6291
we now exit the function after the first successful wait call.
6292
(do_getline_redir, do_getline): Handle case where get_a_record
6293
returns -2.
6294
(errno_io_retry): New function to decide whether an I/O operation should
6295
be retried.
6296

* gawkapi.c (sym_update_real): Allow updates with AWK_SCALAR and
7533
AWK_VALUE_COOKIE types. After creating a regular variable,
7534
remove the call to unref(node->var_value), since this is not
7535
done elsewhere in the code (see, for example, main.c:init_vars).
7536
If the update is for an existing variable, allow any val_type
7537
except AWK_ARRAY (was previously disallowing AWK_SCALAR and
7538
AWK_VALUE_COOKIE for no apparent reason).
7539
(api_sym_update_scalar): The switch should return false for an
7540
invalid val_type value, so change the AWK_ARRAY case to default.
7541
(valid_subscript_type): Any scalar value is good, so accept any valid
7542
type except AWK_ARRAY.
7543
(api_create_value): Accept only AWK_NUMBER and AWK_STRING values.
7544
Anything else should fail.
