jparse.ref.c

/*
 * A programmer's apology and warning:
 *
 * Sorry (tm Canada :-)) for the appalling condition of the code below.
 *
 * The people who worked on these tools and library did NOT write this code.
 * Well, OK, we DID write this comment and the code from jparse.y and jparse.l
 * as well as the other tools; we refer instead to the code in jparse.tab.c,
 * jparse.tab.h and their respective backup files jparse.tab.ref.c and
 * jparse.tab.ref.h generated by bison, and the jparse.c, jparse.lex.h and their
 * respective backup files jparse.ref.c and jparse.lex.ref.h generated by flex.
 *
 * WARNING: We do NOT recommend that you modify the generated code even though
 * it is digitally odoriferous and has a gleety appearance. Beautification of
 * this code, no matter how disagreeable it may seem, is unwise as such
 * modifications tend to be practically impossible to maintain. Even if this
 * Flying Spaghetti Monster style code tempts you to tweak it, doing so might
 * produce visions and nightmares of Cthulhu-like tentacles grabbing at the very
 * logic of your mind, pulling it down into a hideous maelstrom of code
 * maintenance cacophony.
 *
 * OK, it might not give you nightmares but why take the risk? The point is
 * don't work on this file! Instead work on the bison and flex related source
 * files. See the Makefile for details on how this file was generated. See also
 * run_bison.sh and run_flex.sh.
 *
 * Now some might be tempted to point out this code was originally in support of
 * the International Obfuscated C Code Contest (IOCCC) and that objecting to the
 * output of Bison and Flex borders on programming sanctimoniousness. At first
 * glance, this incongruence is unsustainable. In response we opine that one of
 * the fundamental undertones of the IOCCC is the promotion of good programming
 * through irony by awarding highly obfuscated C code. So, if it helps, we
 * suggest you view this apology in a satirical light, even if you are humour
 * impaired. Nevertheless, we still recommend you to eschew modifying the code
 * below.
 *
 * Thanks in advance for your understanding, and sorry (tm Canada :-)).
 *
 * Of course, on the other hand, the fact the scanner and parser are for JSON
 * might suggest that we shouldn't have to apologise because the JSON spec is
 * objectionable and so are the generated scanner and parser so this apology
 * might very well be superfluous. If one were to then ignore the fact that
 * bison and flex do not care what they are parsing this same person could
 * argue, obviously by some perverted logical fallacies, that bison and flex did
 * their job well. Well, OK they probably DID do their job well but in an
 * objectionable way. :-)
 *
 * P.S. In 2022 April 04, when this comment was initially formed, none of the
 *	people working on this parser/scanner were Canadian. But some of them
 *	have several good friends who live in, or are from Canada. Those
 *	friends say sorry in a fun and friendly way, so we honour those friends
 *	accordingly.

 * Why is it that columns start out at 0 and the line starts out at 1? This is
 * because of the way the scanning works. Whenever a token is matched this macro
 * is run. Each time a token is matched if the column is 0 we have to make sure
 * it is 1 and otherwise we have to increase it: unless it's a tab or a newline.
 * If it's a newline we set the column back to 0 and increase the line. If
 * however it's a tab we increase the column count by 8 as that is the default
 * value for '\t'.
 *
 * Now as far as the final 'else' in the for loop it seems more complicated than
 * it might need to be. This was done during the fixing of error location
 * reporting, specifically with the first column being reported as column 0 and
 * then column 2, but the extra defence in the way it is done does not hurt
 * anything so we have left it as is. Thus if the token is not a newline and not
 * a tab we check if first_column is 0 or if last_column is 0 and if either one
 * is 0, we explicitly set the respective variable to 1. Otherwise we increment
 * the first_column and last_column.

/*
 * low_byte_scan - detect certain low byte values
 *
 * Scan data for bytes in the class: [\x00-\x08\x0e-\x1f]
 *
 * A flex programmer's apology:
 *
 * Whenever a scanner matches a token, the text of the token is stored in
 * the NUL byte terminated string yytext.  The length in yyleng is the same
 * as the value that would be returned by the strlen(3) function, except that
 * flex has it as an int not a size_t (this is why we sometimes cast it as an
 * int as systems like NetBSD think it's a size_t).
 *
 * Even though regular expressions can detect the presence of a NUL (\x00) bytes
 * in a block of data, error reporting and internal pointer advancement
 * appears to assume NUL (\x00) terminated strings AND thus the state machine
 * can become "confused" when scanning a block of data with NUL bytes inside
 * instead of just terminating it.
 *
 * To avoid such problems, we pre-scan the block of data for NUL (\x00) bytes
 * and report their presence if we find any NUL (\x00) bytes in data.
 *
 * The so-called JSON spec does not allow byte values [\x00-\x1f] within
 * JSON strings.  Attempts to modify JSON_STRING to exclude such byte values
 * within a JSON string has not worked well, especially when it comes to
 * printing error messages with strings that contain such bytes.
 *
 * To make it easier for the scanner and error messages, we pre-scan data
 * for bytes in the class: [\x00-\x08\x0e-\x1f].  Compared to [\x00-\x1f],
 * this class allows the following subset of whitespace characters:
 *
 *	\x09	Horizontal Tab (\t)
 *	\x0a	Line Feed (\n)
 *	\x0b	Vertical Tab (\v)
 *	\x0c	Form Feed (\f)
 *	\x0d	Carriage Return (\r)
 *
 *	NOTE: Along with \x20 (space) this represents the ASCII whitespace set.
 *	      We avoid scanning for \x20 (space) by limiting our upper exclusion
 *	      range to \x1f.
 *
 * While this subset of whitespace characters are strictly not allowed in
 * JSON strings, we won't scan for them because it might be reasonable for
 * those characters to used outside elements of JSON syntax:
 *
 * We scan data for bytes in the class: [\x00-\x08\x0e-\x1f].  When such
 * bytes are detected, we increment the external variable and we will indicate to
 * the caller that the JSON is invalid by returning true.
 *
 * We also keep track of newlines.  Not to exclude them, but to make it easy
 * for this routine to reference line number and byte position in the line.
 *
 * When a byte in the class: [\x00-\x08\x0e-\x1f] is detected we consider
 * issuing a warning message that indicates the line number, byte position in
 * the line, and byte value.  To avoid printing a huge flood of warning messages
 * (say should a large block of NUL (\x00) and SOM (\x01) bytes are
 * encountered), we limit the number of NUL (\x00) byte warnings to the first
 * MAX_NUL_BYTES_REPORTED, and limit the number of low ([\x01-\x08\x0e-\x1f]) byte
 * warnings to the first MAX_LOW_BYTES_REPORTED.  Should we find more warnings than
 * the limit, a one time "too many" warning is issues.
 *
 * given:
 *
 *	data	    - pointer to block of data to scan for NUL bytes
 *	len	    - length of data in bytes
 *	low_bytes   - pointer to set the number of low bytes found (that aren't NUL) in
 *	nul_bytes   - pointer to set the number of NUL bytes found in
 *
 * return:
 *	true ==> data == NULL OR len <= 0 OR one or more [\x00-\x08\x0e-\x1f]
 *		 bytes are found OR low_bytes == NULL OR nul_bytes == NULL
 *	false ==> data != NULL AND len > 0 AND no NUL [\x00-\x08\x0e-\x1f] bytes were found
