Summary0001625: [proposal] thread-safe variant of Str library
DescriptionFull_Name: Yutaka OIWA

Submission from: (

How about to provide thread-safe variant of Str library?
It would be useful to have an MT-safe regexp library
in the standard distribution.

Previously, I wrote a thread-safe wrapper for Str library
using mutex, which is [^]
and [^] .

Recently I looked into the "to-be-3.07" CVS version of Str library,
and found that the engine written in C is almost thread-safe.
It seems that all global states are stored in Caml-level variables,
and only thread-unsafe portions of code are two static
temporary variables "re_group" and "re_register" in strstubs.c,
which can easily be moved to either stack or heap.

I think that interface for Str module should not be changed for
both compatibility and convenience. (But some replace-related functions
can be MT-safe without modification to their interface.)
So either providing a new module (like my MtStr), or adding another
set of functions for Str module might be desirable.
