Return 0 (with a warning) for sprintf("%.0g") and sprintf("%.0f")

There is special case code in the sprintf implementation, for simple %f and %g
formats, conditionally compiled in only when NVs are doubles. Under long
doubles, these are handled by the general purpose code, which always returns
0 if the argument is missing. Note that sprintf(" %.0g"), ie a leading space,
sufficient to bypass the special case code, would return the string " 0".

The special case code used to return an empty string, meaning that the
behaviour of sprintf("%.0g") and sprintf("%.0f") was inconsistent between a
perl built with doubles, and a perl with long doubles, and the behaviour of
sprintf("%.0g") and sprintf(" %.0g") was inconsistent.

5b98cd54dff3b163 fixed #62874 - the special case code did not warn, but
changed behaviour to return 0. d347ad18ecf3da70 undid the behaviour change,
viewing it as a regression. However, the tests added in 5b98cd54dff3b163
expose the inconsistency in behaviour between doubles and long doubles.

There should be no inconsistency, hence the only logically consistent
conclusion is that the special case implementation was wrong - it cannot
give results inconsistent with the general code. Hence this commit changes
it to return 0 (with a warning). This is achieved by simply skipping the
special case code, if there are insufficient arguments.

9 years agotries: don't allocate memory at runtime
David Mitchell [Mon, 3 May 2010 12:57:58 +0000 (13:57 +0100)] 
tries: don't allocate memory at runtime

This is an indirect fix for
    [perl #74484] Regex causing exponential runtime+mem usage

The trie runtime code was doing more SAVETMPS than FREETMPS and was thus
growing a large tmps stack on heavy backtracking. Rather than fixing this
directly, I rewrote part of the trie code so that it no longer needs to
allocate memory in S_regmatch (it still does in find_byclass()).

The basic issue is that multiple branches in the trie may trigger an
accept state; for example:

    "abcd" =~ /xyz/abcd.*X|ab.*Y|/

here, words (branches) 2 and 3 are accept states. The original approach
was, at run time, to create a list of accepted word numbers and the
character positions of the end of each of those words. Then run the rest
of the pattern for each word in the list in turn (in word index order).
This requires memory for the list to be allocated and freed.

The new approach involves creating extra info at compile time; in
particular, for each word, a pointer to the previous accepted word (if
any) in the state tree. For example for the above pattern, part of the
state tree may be

      q    b    c    d
    1 -> 2 -> 3 -> 4 -> 5
            (#3)       (#2)

(e.g. at state 1, if the next char is 'a', we transition to state 2).
Here, state 3 is an accept state with word #3, and 5 is an accept state
with word #2. So we build a table indexed by word number, which has
wordinfo[2] = 3, wordinfo[3] = 0, thus building the word chain 2->3->0.

At run time we run the trie to completion, and remember the word
associated with the longest accept state (word #2 above). Then by following
back the chain of .prev fields, we can produce a list of all accepting
words. We then iteratively find the smallest-numbered (ie LH-most) word in
the chain, and run with it. On failure and backtrack, we find the
next-smallest and so on.

Since we are no longer recording the end-position of each word in the
string, we have to recalculate this for each backtrack. We initially
record the end-position of the shortest accepting word, and given that we
know the length of each word, we can calculate the new position each time
as an offset from that first word. Depending on unicode and folding, that
calculation can be cheap or expensive.

This algorithm is optimised for the typical case where there are a small
number (<= 2) accepting states.

This patch creates a new compile-time array, trie->wordinfo[], indexed by
word number, which contains relevant info about each word. This also
supersedes the old trie->newword[] array, whose function of recording
"overspills" of multiple words per accept state, is now handled as part of
the wordinfo[].prev chain.
