Re: readline extension status?

aspell and pspell are mostly under LGPL. Quote from aspell/manual/man-text/F_Copyright.txt: F. Copyright The library and utility program is Copyrighted 2000 by Kevin Atkinson under the LGPL. Certain parts of the library, as indicated at the top of the source file, are under a weaker license. The provided word list is extracted from the word lists provided with Ispell thus it is distributed under the same terms of Ispell. Most of his source files do not have a copyright notice, and some explicitly mention GPL. the wordlists are copyrighted by whoever created them, which is a whole slew of different people/entities. But most of the code is LGPL, I guess.

The recode extension I wrote makes use of the recode library librecode.so. This is being distributed under the LGPL, while the actual recode program, which is not being used by the extension, is available under the GPL. > If the same thing happens again with a more 'fundamental' extension, we > won't give up that easily. > > We can expect the readline extension to be removed in the next release of > PHP. I can't say yet when this is going to happen... Using the documentation I identified the following PHP extensions which use external libraries. I tried to find the licenses of the external libraries against which PHP is being linked. Below is the full list. I find the following GNU GPL or LGPL references: domxml, gettext, gmp, icap, mcal, mcrypt, mhash, mysql, readline, recode, orbit, xslt (Sablotron) if used under GPL part of the license, and dba/dbm if linked against gdbm.
