Reported By: hyamamoto at cybozu dot co dot jp
Status: Bogus
Bug Type: mbstring related
Operating System: Any
PHP Version: 4.3.2
New Comment:
Just for clarification.
1. The original authors haven't allowed those libraries to be
distributed under the PHP license.
2. In contrast to GPL, LGPL doesn't force the PHP group to distribute
the package that contains a LGPL licensed library under the same terms
as LGPL's. Read those terms more carefully.
3. We can redistribute them in any form (binary or source) under any
license unless no additional works are added to the library itself.

Please keep this kind of discussion on the mailing lists,
this is not really a _bug_..

AFAIK, the original author(s) have given permission to distribute under
the terms of the PHP license (for the actual mbstring/jstring part at
least).
It does seem that mbregexp is a derivative work. (it used to be a
separate extension from mbstring before it was introduced into the php
core).
Rui, Moriyoshi and Yasuo might be able to help clear things up here.

According to the header lines of the LGPL source files:
1) mbfilter*.{c,h}
may be written specifically for mbstring by a Japanese.

Ugh. I had no idea it was under the LGPL. Wasn't this thing written
specifically for PHP? And as such, is our version a modified version
of the original? If it has not been modified then we are allowed to
distribute a verbatim copy of it even if it is under the LGPL. It is
only if we modify it and/or distribute something less than the entire
library that we become a derivative work.

The current implementation of mbstring uses two Lesser GNU
General Public License (LGPL) sources.
As LGPL does *not* allow derived softwares to be released
under license terms other than LGPL, the entire PHP sources
must be released under LGPL rather than PHP license.
Alternatively, we may separate mbstring from the main PHP
archive until it becomes LGPL-free.
# As you may know, LGPL *does* allow their sources as
# just (dynamic link) libraries. But mbstring itself
# makes use of LGPL sources as its internal utilities.
The sources are:
1) ext/mbstring/mbfilter*.{c,h}
for multibyte character conversion.
2) ext/mbstring/mbregex.{c,h}
for multibyte regular expression.
Thank you.
