Hi all,

First, I just realized while going through the scanner code after the re2c
changes that there's a bug with heredoc handling (from my code changes last
year, oops) on something like:

<<<EOT
text
fooEOT
text
EOT;

Patch for 5.2 with just that fix:
http://realplain.com/php/heredoc_fix_5_2.diff

For 5.3 and HEAD, I fixed problems with yyleng (some would only affect
highlighting, tokenizer ext, etc.) Double quoted heredocs with tabs/spaces
wouldn't work right (ex: <<< "EOT"). Updated some comments. And this
rule that was added...

<ST_LOOKING_FOR_PROPERTY>{WHITESPACE}+ {
/* do nothing */
goto restart;
}

Would lose that whitespace in highlighter, etc. or miss counting line
numbers. Speaking of line numbers, I also removed the
CG(comment_start_line) variable since I can't see that it's needed anywhere,
and CG(zend_lineno) works for the "Unterminated comment..." warning (which
isn't working right now anyway :-)).

In HEAD I also tidied up the LNUM/HNUM rules which lost their tabs and Z_*
macros a year ago (v1.164).

    Thanks Matt,

    I'll review these and merge them in with my other scanner fixes.

    Hi Scott,

    I noticed that Nuno changed yyless() to be like flex after your commit (not
    in HEAD? I considered that, but figured you guys wanted it different :-)),
    but now the heredoc end part is wrong again (hehe), and I see Tony reported
    the broken tests... Attached patch puts it back to pre-re2c state. Also
    remembered a useless "case EOF;" to remove in zendlex() to match HEAD's
    (added at end of '05 (v1.647.2.18) for bug #35382, later fixed in the
    scanner; doesn't look like it ever did much anyway).

    BTW, maybe you could change the name in that 5.2 NEWS entry to just "Matt"?
    No big deal, but that's what it's been other than the first few entries. :-)


    Thanks,
    Matt

    Patch applied, thanks!
    I haven't merged my other patch to HEAD yet, but I'll do so ASAP.

    Thanks,
    Nuno

    We use short names only for people with a php.net account.

    Thanks for the fixes anyway.

    Well, now that I have a php.net account, and 5.2.6 will be released, can
    someone change my name? :-) Unless I'm granted access to do it myself...?

    Didn't know that about short names -- I see my name 11 times in the 5.2
    NEWS, and the last 6 are just Matt. I think Ilia just started using that
    after the first 5. :-P
