Hi,
A few comments on the patch:
A) for licensing reasons we should try to keep as few readline only things as possible in there (gpl
vs. php license)
B) thread safty isn't an issue for readline but you still should do the init and deinit in
rinit/rshutdown not minit/mshutdown, probably also do only bind_key_functions =NULL in rinit and
init the hashtable on demand later.
C) don't compare the r result of zend_hash_find and others against -1 or such but use
SUCCESS/FAILURE
D) i don't really like new features in 5.3 anymore at this stage
E) please log a bug and attach the patch so we can track this
Johannes
P.s. sorry for top posting ...
