* Omnibus strict and lax version parsingDavid Golden2010-01-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Authors: John Peacock, David Golden and Zefram The goal of this mega-patch is to enforce strict rules for version numbers provided to 'package NAME VERSION' while formalizing the prior, lax rules used for version object creation. Parsing for use() is unchanged. version.pm adds two globals, $STRICT and $LAX, containing regular expressions that define the rules. There are two additional functions -- version::is_strict and version::is_lax -- that test an argument against these rules. However, parsing of strings that might contain version numbers is done in core via the Perl_scan_version function, which may be called during compilation or may be called later when version objects are created by Perl_new_version or Perl_upg_version. A new helper function, Perl_prescan_version, has been added to validate a string under either strict or lax rules. This is used in toke.c for 'package NAME VERSION' in strict mode and by Perl_scan_version in lax mode. It matches the behavior of the verison.pm regular expressions, but does not use them directly. A new test file, comp/packagev.t, validates strict and lax behaviors of 'package NAME VERSION' and 'version->new(VERSION)' respectively and verifies their behavior against the $STRICT and $LAX regular expressions, as well. Validating these two implementation should help ensure they each work as intended. Other files and tests have been modified as necessary to support these changes. There is remaining work to be done in a few areas: * documenting all changes in behavior and new functions * determining proper treatment of "," as decimal separators in various locales * updating diagnostics for new error messages * porting changes back to the version.pm distribution on CPAN, including pure-Perl versions

* lexer APIZefram2009-11-151-0/+31
| | | | | | | | | Attached is a patch that adds a public API for the lowest layers of lexing. This is meant to provide a solid foundation for the parsing that Devel::Declare and similar modules do, and it complements the pluggable keyword mechanism. The API consists of some existing variables combined with some new functions, all marked as experimental (which making them public certainly is).

* Bareword sub lookupsZefram2009-11-081-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is a patch that changes how the tokeniser looks up subroutines, when they're referenced by a bareword, for prototype and const-sub purposes. Formerly, it has looked up bareword subs directly in the package, which is contrary to the way the generated op tree looks up the sub, via an rv2cv op. The patch makes the tokeniser generate the rv2cv op earlier, and dig around in that. The motivation for this is to allow modules to hook the rv2cv op creation, to affect the name->subroutine lookup process. Currently, such hooking affects op execution as intended, but everything goes wrong with a bareword ref where the tokeniser looks at some unrelated CV, or a blank space, in the package. With the patch in place, an rv2cv hook correctly affects the tokeniser and therefore the prototype-based aspects of parsing. The patch also changes ck_subr (which applies the argument context and checking parts of prototype behaviour) to handle subs referenced by an RV const op inside the rv2cv, where formerly it would only handle a gv op inside the rv2cv. This is to support the most likely kind of modified rv2cv op. The attached patch is the resulting revised version of the bareword sub patch. It incorporates the original patch (allowing rv2cv op hookers to control prototype processing), the GV-downgrading addition, and a mention in perldelta.

* RT#69616: regexp SVs lose regexpness in assignmentBen Morrow2009-10-221-3/+3
| | | | | | | | It uses reg_temp_copy to copy the REGEXP onto the destination SV without needing to copy the underlying pattern structure. This means changing the prototype of reg_temp_copy, so it can copy onto a passed-in SV, but it isn't API (and probably shouldn't be exported) so I don't think this is a problem.
* Remove the PERLIO * argument to S_filter_gets(), as it's always PL_rsfpNicholas Clark2009-10-211-4/+3
| | | | | | | | Conceptually it's also wrong, as if there are source filters, the passed-in file handle is not passed up the stack of filters for the topmost filter to use to read from. It was in the parameter list from the first creation of filter_gets() in 16d20bd98cd29be76029ebf04027a7edd34d817b, when calls to sv_gets() were replaced by it.

Various conflicts with the passage of time resolved, 'register' removed, and a $VERSION bump.

| | | | | | | Replace ckWARN{,2,3,4}() && Perl_warner() with it, which trades reduced code size (about 0.2%), for 1 more function call if warnings are not enabled. However, if we're now in the L1 or L2 cache when we weren't previously, that's still going to be a speed win.

* Add 'package NAME VERSION' syntaxDavid Golden2009-10-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for setting the $VERSION of a namespace when the namespace is declared with 'package'. It eliminates the need for 'our $VERSION = ...' and similar constructs. E.g. package Foo::Bar 1.23; # $Foo::Bar::VERSION == 1.23 There are several advantages to this: * VERSION is parsed in *exactly* the same way as 'use NAME VERSION' * $VERSION is set at compile time * Eliminates '$VERSION = ...' and 'eval $VERSION' clutter * As it requires VERSION to be a numeric literal or v-string literal, it can be statically parsed by toolchain modules without 'eval' the way MM->parse_version does for '$VERSION = ...' * Alpha versions with underscores do not need to be quoted; static parsing will preserve the underscore, but during compilation, Perl will remove underscores as it does for all numeric literals During development of this, there was discussion on #corehackers and elsewhere that this should also allow other metadata to be set such as "status" (stable/alpha) or "author/authority". On reflection, those metadata are not very well defined yet and likely should never be encoded into Perl core parsing so they can be freely changed in the future. (They could perhaps be achieved via a comment on the same line as 'package NAME VERSION'.) Version numbers, however, already have a very specific definition and use defined in the core through 'use NAME VERSION'. This patch merely provides appropriate symmetry for setting $VERSION with the exact same parsing and semantics as 'use'. It does not break old code with only 'package NAME', but code that uses 'package NAME VERSION' will need to be restricted to perl 5.11.X. This is analogous to the change to open() from two-args to three-args. Users requiring the latest Perl will benefit, and perhaps N years from now it will become standard practice when Perl 5.12 is targeted the way that 5.6 is today. The patch does not prevent 'package NAME VERSION' from being used multiple times for the same package with different version numbers, but nothing prevents $VERSION from being modified arbitrarily at runtime, either, so I see no urgen reason to add limitations or warnings so long as Perl uses a global $VERSION variable for package version numbers. I am posting this patch to the p5p list for discussion and review. If there seems to be general assent (or lack of dissent), I will go ahead and commit the patch to blead.

* Speed up repeatcpy() by at least 40% for 1-char or numerous repeatsVincent Pit2009-08-271-3/+3
| | | | | | | | | | | | And don't make it receive the interpreter anymore. For 1-char repeats, use memset(). Otherwise, use the old implementation up to some (small) length, and then use memcpy() in a binary manner, based on what we previously copied. Note that we use memcpy() so both strings shouldn't overlap. The previous implementation didn't allow this as well. This would be a good place to use the restrict keyword from C99. I'm not sure if Configure has a probe for it.
