Glock" Date: Tue, 17 Mar 2026 23:17:55 +0100 Subject: [PATCH 06/13] Fix file test on underscore after JAR path and File::Path relative paths 1. FileTestOperator: Handle null lastBasicAttr when using underscore (_) filehandle after testing a JAR path. Fall back to re-testing the file. 2. File::Path: Fix _make_path_perl to handle relative paths correctly. Previously "_build" became "/_build" (absolute). Now relative paths are preserved. These fixes allow Module::Build Build.PL to complete successfully.

If the file does not exist then it will be created. Assigning +a single integer to a hash element will cause both the access and +modification times to be changed to that value. Alternatively a reference to +an array of two values can be passed. The first array element will be used to +set the access time and the second element will be used to set the modification +time. + +=head1 SEE ALSO + +L + +=head1 AUTHOR + +Graham Barr.

JSON::PP works as +a fallback module when you use L module without having +installed JSON::XS. + +Because of this fallback feature of JSON.pm, JSON::PP tries not to +be more JavaScript-friendly than JSON::XS (i.e. not to escape extra +characters such as U+2028 and U+2029, etc), +in order for you not to lose such JavaScript-friendliness silently +when you use JSON.pm and install JSON::XS for speed or by accident. +If you need JavaScript-friendly RFC7159-compliant pure perl module, +try L, which is derived from L web +framework and is also smaller and faster than JSON::PP. + +JSON::PP has been in the Perl core since Perl 5.14, mainly for +CPAN toolchain modules to parse META.json. + +=head1 FUNCTIONAL INTERFACE + +This section is taken from JSON::XS almost verbatim. C +and C are exported by default. + +=head2 encode_json + + $json_text = encode_json $perl_scalar + +Converts the given Perl data structure to a UTF-8 encoded, binary string +(that is, the string contains octets only). Croaks on error. + +This function call is functionally identical to: + + $json_text = JSON::PP->new->utf8->encode($perl_scalar) + +Except being faster. + +=head2 decode_json + + $perl_scalar = decode_json $json_text + +The opposite of C: expects an UTF-8 (binary) string and tries +to parse that as an UTF-8 encoded JSON text, returning the resulting +reference. Croaks on error. + +This function call is functionally identical to: + + $perl_scalar = JSON::PP->new->utf8->decode($json_text) + +Except being faster. + +=head2 JSON::PP::is_bool + + $is_boolean = JSON::PP::is_bool($scalar) + +Returns true if the passed scalar represents either JSON::PP::true or +JSON::PP::false, two constants that act like C<1> and C<0> respectively +and are also used to represent JSON C and C in Perl strings. + +On perl 5.36 and above, will also return true when given one of perl's +standard boolean values, such as the result of a comparison. + +See L, below, for more information on how JSON values are mapped to +Perl. + +=head1 OBJECT-ORIENTED INTERFACE + +This section is also taken from JSON::XS. + +The object oriented interface lets you configure your own encoding or +decoding style, within the limits of supported formats. + +=head2 new + + $json = JSON::PP->new + +Creates a new JSON::PP object that can be used to de/encode JSON +strings. All boolean flags described below are by default I +(with the exception of C, which defaults to I since +version C<4.0>). + +The mutators for flags all return the JSON::PP object again and thus calls can +be chained: + + my $json = JSON::PP->new->utf8->space_after->encode({a => [1,2]}) + => {"a": [1, 2]} + +=head2 ascii + + $json = $json->ascii([$enable]) + + $enabled = $json->get_ascii + +If C<$enable> is true (or missing), then the C method will not +generate characters outside the code range C<0..127> (which is ASCII). Any +Unicode characters outside that range will be escaped using either a +single \uXXXX (BMP characters) or a double \uHHHH\uLLLLL escape sequence, +as per RFC4627. The resulting encoded JSON text can be treated as a native +Unicode string, an ascii-encoded, latin1-encoded or UTF-8 encoded string, +or any other superset of ASCII. + +If C<$enable> is false, then the C method will not escape Unicode +characters unless required by the JSON syntax or other flags.

The C method +will not be affected in any way by this flag, as C by default +expects Unicode, which is a strict superset of latin1. + +If C<$enable> is false, then the C method will not escape Unicode +characters unless required by the JSON syntax or other flags. + +See also the section I later in this document. + +The main use for this flag is efficiently encoding binary data as JSON +text, as most octets will not be escaped, resulting in a smaller encoded +size. The disadvantage is that the resulting JSON text is encoded +in latin1 (and must correctly be treated as such when storing and +transferring), a rare encoding for JSON.

You can set incompatible +boolean objects (like L), but when you C a data structure +with such boolean objects, you still need to enable C +(and add a C method if necessary). + +Calling this method without any arguments will reset the booleans +to their default values. + +C will return both C<$false> and C<$true> values, or +the empty list when they are set to the default. + +=head2 core_bools + + $json->core_bools([$enable]); + +If C<$enable> is true (or missing), then C, will produce standard +perl boolean values.

This setting can slow down decoding +considerably. + +When C<$coderef> is omitted or undefined, any existing callback will +be removed and C will not change the deserialised hash in any +way. + +Example, convert all JSON objects into the integer 5: + + my $js = JSON::PP->new->filter_json_object(sub { 5 }); + # returns [5] + $js->decode('[{}]'); + # returns 5 + $js->decode('{"a":1, "b":2}'); + +=head2 filter_json_single_key_object + + $json = $json->filter_json_single_key_object($key [=> $coderef]) + +Works remotely similar to C, but is only called for +JSON objects having a single key named C<$key>. + +This C<$coderef> is called before the one specified via +C, if any. It gets passed the single value in the JSON +object. If it returns a single value, it will be inserted into the data +structure. If it returns nothing (not even C but the empty list), +the callback from C will be called next, as if no +single-key callback were specified. + +If C<$coderef> is omitted or undefined, the corresponding callback will be +disabled. There can only ever be one callback for a given key. + +As this callback gets called less often then the C +one, decoding speed will not usually suffer as much. Therefore, single-key +objects make excellent targets to serialise Perl objects into, especially +as single-key JSON objects are as close to the type-tagged value concept +as JSON gets (it's basically an ID/VALUE tuple).

While this module always has to keep both JSON text and resulting +Perl data structure in memory at one time, it does allow you to parse a +JSON stream incrementally. It does so by accumulating text until it has +a full JSON object, which it then can decode. This process is similar to +using C to see if a full JSON object is available, but +is much more efficient (and can be implemented with a minimum of method +calls). + +JSON::PP will only attempt to parse the JSON text once it is sure it +has enough text to get a decisive result, using a very simple but +truly incremental parser. This means that it sometimes won't stop as +early as the full parser, for example, it doesn't detect mismatched +parentheses. The only thing it guarantees is that it starts decoding as +soon as a syntactically valid JSON text has been seen. This means you need +to set resource limits (e.g. C) to ensure the parser will stop +parsing in the presence if syntax errors. + +The following methods implement this incremental parser. + +=head2 incr_parse + + $json->incr_parse( [$string] ) # void context + + $obj_or_undef = $json->incr_parse( [$string] ) # scalar context + + @obj_or_empty = $json->incr_parse( [$string] ) # list context + +This is the central parsing function. It can both append new text and +extract objects from the stream accumulated so far (both of these +functions are optional). + +If C<$string> is given, then this string is appended to the already +existing JSON fragment stored in the C<$json> object. + +After that, if the function is called in void context, it will simply +return without doing anything further. This can be used to add more text +in as many chunks as you want. + +If the method is called in scalar context, then it will try to extract +exactly I JSON object. If that is successful, it will return this +object, otherwise it will return C. If there is a parse error, +this method will croak just as C would do (one can then use +C to skip the erroneous part). This is the most common way of +using the method. + +And finally, in list context, it will try to extract as many objects +from the stream as it can find and return them, or the empty list +otherwise. For this to work, there must be no separators (other than +whitespace) between the JSON objects or arrays, instead they must be +concatenated back-to-back. If an error occurs, an exception will be +raised as in the scalar context case. Note that in this case, any +previously-parsed JSON texts will be lost. + +Example: Parse some JSON arrays/objects in a given string and return +them. + + my @objs = JSON::PP->new->incr_parse ("[5][7][1,2]"); + +=head2 incr_text + + $lvalue_string = $json->incr_text + +This method returns the currently stored JSON fragment as an lvalue, that +is, you can manipulate it. This I works when a preceding call to +C in I successfully returned an object. Under +all other circumstances you must not call this function (I mean it. +although in simple tests it might actually work, it I fail under +real world conditions). As a special exception, you can also call this +method before having parsed anything. + +That means you can only use this function to look at or manipulate text +before or after complete JSON objects, not while the parser is in the +middle of parsing a JSON object. + +This function is useful in two cases: a) finding the trailing text after a +JSON object or b) parsing multiple JSON objects separated by non-JSON text +(such as commas). + +=head2 incr_skip + + $json->incr_skip + +This will reset the state of the incremental parser and will remove +the parsed text from the input buffer so far. This is useful after +C died, in which case the input buffer and incremental parser +state is left unchanged, to skip the text parsed so far and to reset the +parse state. + +The difference to C is that only text until the parse error +occurred is removed. + +=head2 incr_reset + + $json->incr_reset + +This completely resets the incremental parser, that is, after this call, +it will be as if the parser had never parsed anything. + +This is useful if you want to repeatedly parse JSON objects and want to +ignore any trailing data, which means you have to reset the parser after +each successful decode. + +=head1 MAPPING + +Most of this section is also taken from JSON::XS. + +This section describes how JSON::PP maps Perl values to JSON values and +vice versa. These mappings are designed to "do the right thing" in most +circumstances automatically, preserving round-tripping characteristics +(what you put in comes out as something equivalent). + +For the more enlightened: note that in the following descriptions, +lowercase I refers to the Perl interpreter, while uppercase I +refers to the abstract Perl language itself. + +=head2 JSON -> PERL + +=over 4 + +=item object + +A JSON object becomes a reference to a hash in Perl. No ordering of object +keys is preserved (JSON does not preserve object key ordering itself). + +=item array + +A JSON array becomes a reference to an array in Perl. + +=item string + +A JSON string becomes a string scalar in Perl - Unicode codepoints in JSON +are represented by the same codepoints in the Perl string, so no manual +decoding is necessary. + +=item number + +A JSON number becomes either an integer, numeric (floating point) or +string scalar in perl, depending on its range and any fractional parts. On +the Perl level, there is no difference between those as Perl handles all +the conversion details, but an integer may take slightly less memory and +might represent more values exactly than floating point numbers. + +If the number consists of digits only, JSON::PP will try to represent +it as an integer value. If that fails, it will try to represent it as +a numeric (floating point) value if that is possible without loss of +precision. Otherwise it will preserve the number as a string value (in +which case you lose roundtripping ability, as the JSON number will be +re-encoded to a JSON string). + +Numbers containing a fractional or exponential part will always be +represented as numeric (floating point) values, possibly at a loss of +precision (in which case you might lose perfect roundtripping ability, but +the JSON number will still be re-encoded as a JSON number). + +Note that precision is not accuracy - binary floating point values cannot +represent most decimal fractions exactly, and when converting from and to +floating point, JSON::PP only guarantees precision up to but not including +the least significant bit. + +When C is enabled, big integer values and any numeric +values will be converted into L and L +objects respectively, without becoming string scalars or losing +precision. + +=item true, false + +These JSON atoms become C and C, +respectively. They are overloaded to act almost exactly like the numbers +C<1> and C<0>. You can check whether a scalar is a JSON boolean by using +the C function. + +=item null + +A JSON null atom becomes C in Perl. + +=item shell-style comments (C<< # I >>) + +As a nonstandard extension to the JSON syntax that is enabled by the +C setting, shell-style comments are allowed. They can start +anywhere outside strings and go till the end of the line. + +=item tagged values (C<< (I)I >>). + +Another nonstandard extension to the JSON syntax, enabled with the +C setting, are tagged values. In this implementation, the +I must be a perl package/class name encoded as a JSON string, and the +I must be a JSON array encoding optional constructor arguments. + +See L, below, for details. + +=back + + +=head2 PERL -> JSON + +The mapping from Perl to JSON is slightly more difficult, as Perl is a +truly typeless language, so we can only guess which JSON type is meant by +a Perl value. + +=over 4 + +=item hash references + +Perl hash references become JSON objects. As there is no inherent +ordering in hash keys (or JSON objects), they will usually be encoded +in a pseudo-random order. JSON::PP can optionally sort the hash keys +(determined by the I flag and/or I property), so +the same data structure will serialise to the same JSON text (given +same settings and version of JSON::PP), but this incurs a runtime +overhead and is only rarely useful, e.g. when you want to compare some +JSON text against another for equality. + +=item array references + +Perl array references become JSON arrays. + +=item other references + +Other unblessed references are generally not allowed and will cause an +exception to be thrown, except for references to the integers C<0> and +C<1>, which get turned into C and C atoms in JSON. You can +also use C and C to improve +readability. + + to_json [\0, JSON::PP::true] # yields [false,true] + +=item JSON::PP::true, JSON::PP::false + +These special values become JSON true and JSON false values, +respectively. You can also use C<\1> and C<\0> directly if you want. + +=item JSON::PP::null + +This special value becomes JSON null. + +=item blessed objects + +Blessed objects are not directly representable in JSON, but C +allows various ways of handling objects. See L, +below, for details. + +=item simple scalars + +Simple Perl scalars (any scalar that is not a reference) are the most +difficult objects to encode: JSON::PP will encode undefined scalars as +JSON C values, scalars that have last been used in a string context +before encoding as JSON strings, and anything else as number value: + + # dump as number + encode_json [2] # yields [2] + encode_json [-3.0e17] # yields [-3e+17] + my $value = 5; encode_json [$value] # yields [5] + + # used as string, so dump as string + print $value; + encode_json [$value] # yields ["5"] + + # undef becomes null + encode_json [undef] # yields [null] + +You can force the type to be a JSON string by stringifying it: + + my $x = 3.1; # some variable containing a number + "$x"; # stringified + $x .= ""; # another, more awkward way to stringify + print $x; # perl does it for you, too, quite often + # (but for older perls) + +You can force the type to be a JSON number by numifying it: + + my $x = "3"; # some variable containing a string + $x += 0; # numify it, ensuring it will be dumped as a number + $x *= 1; # same thing, the choice is yours. + +You can not currently force the type in other, less obscure, ways. + +Since version 2.91_01, JSON::PP uses a different number detection logic +that converts a scalar that is possible to turn into a number safely. +The new logic is slightly faster, and tends to help people who use older +perl or who want to encode complicated data structure. However, this may +results in a different JSON text from the one JSON::XS encodes (and +thus may break tests that compare entire JSON texts). If you do +need the previous behavior for compatibility or for finer control, +set PERL_JSON_PP_USE_B environmental variable to true before you +C JSON::PP (or JSON.pm). + +Note that numerical precision has the same meaning as under Perl (so +binary to decimal conversion follows the same rules as in Perl, which +can differ to other languages). Also, your perl interpreter might expose +extensions to the floating point numbers of your platform, such as +infinities or NaN's - these cannot be represented in JSON, and it is an +error to pass those in. + +JSON::PP (and JSON::XS) trusts what you pass to C method +(or C function) is a clean, validated data structure with +values that can be represented as valid JSON values only, because it's +not from an external data source (as opposed to JSON texts you pass to +C or C, which JSON::PP considers tainted and +doesn't trust). As JSON::PP doesn't know exactly what you and consumers +of your JSON texts want the unexpected values to be (you may want to +convert them into null, or to stringify them with or without +normalisation (string representation of infinities/NaN may vary +depending on platforms), or to croak without conversion), you're advised +to do what you and your consumers need before you encode, and also not +to numify values that may start with values that look like a number +(including infinities/NaN), without validating. + +=back + +=head2 OBJECT SERIALISATION + +As JSON cannot directly represent Perl objects, you have to choose between +a pure JSON representation (without the ability to deserialise the object +automatically again), and a nonstandard extension to the JSON syntax, +tagged values. + +=head3 SERIALISATION + +What happens when C encounters a Perl object depends on the +C, C, C and C +settings, which are used in this order: + +=over 4 + +=item 1. C is enabled and the object has a C method. + +In this case, C creates a tagged JSON value, using a nonstandard +extension to the JSON syntax. + +This works by invoking the C method on the object, with the first +argument being the object to serialise, and the second argument being the +constant string C to distinguish it from other serialisers. + +The C method can return any number of values (i.e. zero or +more). These values and the paclkage/classname of the object will then be +encoded as a tagged JSON value in the following format: + + ("classname")[FREEZE return values...] + +e.g.: + + ("URI")["http://www.google.com/"] + ("MyDate")[2013,10,29] + ("ImageData::JPEG")["Z3...VlCg=="] + +For example, the hypothetical C C method might use the +objects C and C members to encode the object: + + sub My::Object::FREEZE { + my ($self, $serialiser) = @_; + + ($self->{type}, $self->{id}) + } + +=item 2. C is enabled and the object has a C method. + +In this case, the C method of the object is invoked in scalar +context. It must return a single scalar that can be directly encoded into +JSON. This scalar replaces the object in the JSON text. + +For example, the following C method will convert all L +objects to JSON strings when serialised. The fact that these values +originally were L objects is lost. + + sub URI::TO_JSON { + my ($uri) = @_; + $uri->as_string + } + +=item 3. C is enabled and the object is a C or C. + +The object will be serialised as a JSON number value. + +=item 4. C is enabled. + +The object will be serialised as a JSON null value. + +=item 5. none of the above + +If none of the settings are enabled or the respective methods are missing, +C throws an exception. + +=back + +=head3 DESERIALISATION + +For deserialisation there are only two cases to consider: either +nonstandard tagging was used, in which case C decides, +or objects cannot be automatically be deserialised, in which +case you can use postprocessing or the C or +C callbacks to get some real objects our of +your JSON. + +This section only considers the tagged value case: a tagged JSON object +is encountered during decoding and C is disabled, a parse +error will result (as if tagged values were not part of the grammar). + +If C is enabled, C will look up the C method +of the package/classname used during serialisation (it will not attempt +to load the package as a Perl module). If there is no such method, the +decoding will fail with an error. + +Otherwise, the C method is invoked with the classname as first +argument, the constant string C as second argument, and all the +values from the JSON array (the values originally returned by the +C method) as remaining arguments. + +The method must then return the object. While technically you can return +any Perl scalar, you might have to enable the C setting to +make that work in all cases, so better return an actual blessed reference. + +As an example, let's implement a C function that regenerates the +C from the C example earlier: + + sub My::Object::THAW { + my ($class, $serialiser, $type, $id) = @_; + + $class->new (type => $type, id => $id) + } + + +=head1 ENCODING/CODESET FLAG NOTES + +This section is taken from JSON::XS. + +The interested reader might have seen a number of flags that signify +encodings or codesets - C, C and C. There seems to be +some confusion on what these do, so here is a short comparison: + +C controls whether the JSON text created by C (and expected +by C) is UTF-8 encoded or not, while C and C only +control whether C escapes character values outside their respective +codeset range. Neither of these flags conflict with each other, although +some combinations make less sense than others. + +Care has been taken to make all flags symmetrical with respect to +C and C, that is, texts encoded with any combination of +these flag values will be correctly decoded when the same flags are used +- in general, if you use different flag settings while encoding vs. when +decoding you likely have a bug somewhere. + +Below comes a verbose discussion of these flags. Note that a "codeset" is +simply an abstract set of character-codepoint pairs, while an encoding +takes those codepoint numbers and I them, in our case into +octets. Unicode is (among other things) a codeset, UTF-8 is an encoding, +and ISO-8859-1 (= latin 1) and ASCII are both codesets I encodings at +the same time, which can be confusing. + +=over 4 + +=item C flag disabled + +When C is disabled (the default), then C/C generate +and expect Unicode strings, that is, characters with high ordinal Unicode +values (> 255) will be encoded as such characters, and likewise such +characters are decoded as-is, no changes to them will be done, except +"(re-)interpreting" them as Unicode codepoints or Unicode characters, +respectively (to Perl, these are the same thing in strings unless you do +funny/weird/dumb stuff). + +This is useful when you want to do the encoding yourself (e.g. when you +want to have UTF-16 encoded JSON texts) or when some other layer does +the encoding for you (for example, when printing to a terminal using a +filehandle that transparently encodes to UTF-8 you certainly do NOT want +to UTF-8 encode your data first and have Perl encode it another time). + +=item C flag enabled + +If the C-flag is enabled, C/C will encode all +characters using the corresponding UTF-8 multi-byte sequence, and will +expect your input strings to be encoded as UTF-8, that is, no "character" +of the input string must have any value > 255, as UTF-8 does not allow +that. + +The C flag therefore switches between two modes: disabled means you +will get a Unicode string in Perl, enabled means you get an UTF-8 encoded +octet/binary string in Perl. + +=item C or C flags enabled + +With C (or C) enabled, C will escape characters +with ordinal values > 255 (> 127 with C) and encode the remaining +characters as specified by the C flag. + +If C is disabled, then the result is also correctly encoded in those +character sets (as both are proper subsets of Unicode, meaning that a +Unicode string with all character values < 256 is the same thing as a +ISO-8859-1 string, and a Unicode string with all character values < 128 is +the same thing as an ASCII string in Perl). + +If C is enabled, you still get a correct UTF-8-encoded string, +regardless of these flags, just some more characters will be escaped using +C<\uXXXX> then before. + +Note that ISO-8859-1-I strings are not compatible with UTF-8 +encoding, while ASCII-encoded strings are. That is because the ISO-8859-1 +encoding is NOT a subset of UTF-8 (despite the ISO-8859-1 I being +a subset of Unicode), while ASCII is. + +Surprisingly, C will ignore these flags and so treat all input +values as governed by the C flag. If it is disabled, this allows you +to decode ISO-8859-1- and ASCII-encoded strings, as both strict subsets of +Unicode. If it is enabled, you can correctly decode UTF-8 encoded strings. + +So neither C nor C are incompatible with the C flag - +they only govern when the JSON output engine escapes a character or not. + +The main use for C is to relatively efficiently store binary data +as JSON, at the expense of breaking compatibility with most JSON decoders. + +The main use for C is to force the output to not contain characters +with values > 127, which means you can interpret the resulting string +as UTF-8, ISO-8859-1, ASCII, KOI8-R or most about any character set and +8-bit-encoding, and still get the same data structure back. This is useful +when your channel for JSON transfer is not 8-bit clean or the encoding +might be mangled in between (e.g. in mail), and works because ASCII is a +proper subset of most 8-bit and multibyte encodings in use in the world. + +=back + +=head1 BUGS + +Please report bugs on a specific behavior of this module to RT or GitHub +issues (preferred): + +L + +L + +As for new features and requests to change common behaviors, please +ask the author of JSON::XS (Marc Lehmann, Eschmorp[at]schmorp.deE) +first, by email (important!), to keep compatibility among JSON.pm backends. + +Generally speaking, if you need something special for you, you are advised +to create a new module, maybe based on L, which is smaller and +written in a much cleaner way than this module. + +=head1 SEE ALSO + +The F command line utility for quick experiments. + +L, L, and L for faster alternatives. +L and L for easy migration. + +L and L for older perl users. + +RFC4627 (L) + +RFC7159 (L) + +RFC8259 (L) + +=head1 AUTHOR + +Makamaka Hannyaharamitu, Emakamaka[at]cpan.orgE + +=head1 CURRENT MAINTAINER + +Kenichi Ishigaki, Eishigaki[at]cpan.orgE + +=head1 COPYRIGHT AND LICENSE + +Copyright 2007-2016 by Makamaka Hannyaharamitu + +Most of the documentation is taken from JSON::XS by Marc Lehmann + +This library is free software; you can redistribute it and/or modify +it under the same terms as Perl itself. + +=cut diff --git a/src/main/perl/lib/JSON/PP/Boolean.pm b/src/main/perl/lib/JSON/PP/Boolean.pm new file mode 100644 index 000000000..146446e93 --- /dev/null +++ b/src/main/perl/lib/JSON/PP/Boolean.pm @@ -0,0 +1,43 @@ +package JSON::PP::Boolean; + +use strict; +use warnings; +use overload (); +overload::unimport('overload', qw(0+ ++ -- fallback)); +overload::import('overload', + "0+" => sub { ${$_[0]} }, + "++" => sub { $_[0] = ${$_[0]} + 1 }, + "--" => sub { $_[0] = ${$_[0]} - 1 }, + fallback => 1, +); + +our $VERSION = '4.16'; + +1; + +__END__ + +=head1 NAME + +JSON::PP::Boolean - dummy module providing JSON::PP::Boolean + +=head1 SYNOPSIS + + # do not "use" yourself + +=head1 DESCRIPTION + +This module exists only to provide overload resolution for Storable and similar modules.

Since JVM cannot fork, we detect this pattern at runtime and handle it specially: 1. open FH, "-|" without command sets pending state, returns 0 (child) 2. exec @cmd detects pending state, runs command, captures output 3. Throws ForkOpenCompleteException caught by RuntimeCode.apply() 4. Subroutine returns captured output as if parent branch executed This transparently supports Module::Build's _backticks() pattern without requiring any patches to Module::Build itself.

This class manages the state needed to emulate Perl's fork-open pattern + * ({@code open FH, "-|"}) on the JVM, which doesn't support fork(). + * + *

How Fork-Open Emulation Works

+ * + *

In Perl, {@code my $pid = open FH, "-|"} forks the process: + *

    + *
  • Parent gets child's PID, reads from FH (child's stdout)
    • + *
  • Child gets 0, typically calls exec to run a command
    • + *
+ * + *

Since JVM can't fork, we emulate this pattern: + *

    + *
  1. When {@code open FH, "-|"} is called without a command, we store a + * pending state and return 0 (pretending to be the "child")
    2. + *
  2. When {@code exec @cmd} is called, we detect the pending state, + * create the pipe using 3-arg semantics, and signal to return to + * the "parent" code path with the pipe ready
    3. + *
+ * + *

Supported Patterns

+ * 
{@code
+ * # Classic if/else
+ * my $pid = open FH, "-|";
+ * if ($pid) { ... } else { exec @cmd }
+ * 
+ * # or-exec idiom
+ * open FH, "-|" or exec @cmd;
+ * }
+ * + *
