ReadMe for relic.py (a Mozilla relicensing tool)
|
|
|
|
|
|
This script is intended to facilitate re-licensing the Mozilla source
|
|
tree pursuant to <http://mozilla.org/MPL/>. It cannot do the full job
|
|
automatically but handles most of the grunt work.

The Problem:
|
|
|
|
The basic problem is that Mozilla has a lot of files. The goal is to have
|
|
all the files (with a few minor exceptions) contain a leading license
|
|
block that is either the MPL/GPL/LGPL tri-license or the NPL/GPL/LGPL
|
|
tri-license. Because this was never rigorously enforced a lot of cleanup
|
|
is necessary to correct license blocks in Mozilla's files. This script
|
|
will traverse the given directory(s)/file(s) and fixup the leading
|
|
license block, or give an error message explaining why it cannot. (It
|
|
also has modes to just scan for and summarize license info.)
|
|
|
|
|
|
Getting Started:
|
|
|
|
While 'relic.py' is probably quite portable to Windows it has not been
|
|
tested there. There may be some hidden path-delimiter bugs. It is
|
|
probably best to just run this script on Linux.
|
|
|
|
To use:
|
|
- crack the relic-<version>.tar.gz tarball in some directory
|
|
- call './relic.py --help' to learn the basic usage
|
|
- play with './relic.py ...' as desired.
|
|
|
|
|
|
Basic Usage:
|
|
|
|
'relic.py' has a --help option that explains the basic usage but I'll go
|
|
through some examples here. In our examples we will work on re-licensing
|
|
the mozilla/js/src directory tree.
|
|
|
|
'relic.py' has three modes.
|
|
(1) List license info on each file processed (the default)
|
|
|
|
$ ./relic.py mozilla/js/src/jsapi.h
|
|
/js/src/jsapi.h
|
|
... npl/gpl found
|
|
... license block lines: 2-32
|
|
... original code is: Mozilla Communicator client code
|
|
... initially by: Original Code is Netscape Communications Corporation (1998)
|
|
|
|
(2) Gather and dump statistics on the processed files:
|
|
|
|
$ ./relic.py -s mozilla/js/src/jsapi.h
|
|

|
|

|
|
|
|
(3) Re-licensing the given files that need it (i.e. files with a complete
|
|
and correct license block are changed).
|
|
|
|
$ ./relic.py -r mozilla/js/src/jsapi.h
|
|
mozilla/js/src/jsapi.h
|
|
... npl/gpl found, need to relicense
|
|
... original code is: Mozilla Communicator client code
|
|
... initially by: Original Code is Netscape Communications Corporation (1998)
|
|
... replacing lines 2-32 with NPL/GPL/LGPL tri-license
|
|
... backing up to 'mozilla/js/src/jsapi.h~0'
|
|
... done relicensing 'mozilla/js/src/jsapi.h'
|

--------------------- Summary of Results ------------------------
|
|
Files skipped b/c they are binary: 0

If you are trying this as you read this, run the following command to see
|
|
the changes made to jsapi.h:
|
|
|
|
$ diff -c mozilla/js/src/jsapi.h~0 mozilla/js/src/jsapi.h
|
|
|
|
|
|
What Files are Processed:
|
|
|
|
'relic.py' will process any files listed on the command line and will
|
|
recursively process all files in any given directories:
|
|
|
|
$ ./relic.py -s mozilla/js/src
|

The following files are automatically skipped:
|
|
- CVS control directories;
|
|
- files listed in .cvsignore files;
|
|
- all *.s files (there usage of comment delimiters is all over the map);
|
|
- binary files; and
|
|
- any files included in the following global variables in relic.py:
|
|
_g_skip_file_basenames, _g_skip_files, _g_skip_dir_basenames,
|
|
_g_skip_dirs, _g_skip_ext.
|
|
|
|
|
|
Error Handling (--force):
|
|
|
|
There are some situations that relic.py cannot handle. E.g., a file with
|
|
no license block to start with, an IBM license block, a license block
|
|
sufficiently strange enough to baffle relic.py regular expressions. In
|
|
normal operation, when an error is encoutered on any file processing
|
|
stops. This can be annoying, so a --force|-f option was added to force
|
|
relic.py to continue processing files after an error with a file is
|
|
encountered. In all modes of operation errors are summarized at the end.
|
|
|
|
$ ./relic.py -s mozilla/extensions/transformiix/source/xml
|
|
ERROR:relic:This is line is part of the 'Contributor(s):' paragraph but (1) is not indented and (2) does not look like it contains an email address: mozilla/extensions/transformiix/source/xml/XMLDOMUtils.h:20: ' * Keith Visco' (the --force option can be used to skip problematic files and continue processing rather than aborting)
|
|
|
|
$ ./relic.py -sf mozilla/extensions/transformiix/source/xml

Unfinished Business:
|
|
|
|
The following is a list of issues that should be sorted out before this
|
|
should be used to start making patches to the Mozilla tree:
|
|
|
|
- What to do for files that have no 'Initial Developer...' block?
|
|
- What to do for files that have no 'Original Code is...' block?
|
|
- Are there specific files or parts of the mozilla tree that should be
|
|
skipped always, i.e. generated files, files not meant to have leading
|
|
license blocks?
|
|
- What to do for files with the IBM license?
|
|
- Should *.uf be ignored (there are 87 of them in the mozilla tree)?
|
|
- The 'ripl' and lick' scripts' "include licenses" configuration option
|
|
is not supported in anyway by relic.py. Is it necessary? I don't see a
|
|
useful use case.
|
|
- test/x_thread_align_center.xml and test/abs2rel.pl are examples of
|
|
files that are not handled correctly. In the former there is some data
|
|
loss. In the latter the is some cruft left over.

Trent Mick (TrentM@ActiveState.com) originally wrote this script,
|
|
borrowing some from earlier attempts in the name of 'lick', 'lutils.py',
|
|
and 'ripl' (see <http://bugzilla.mozilla.org/show_bug.cgi?id=98089>).
|
|
If you have problems with the script please let me know and hopefully I
|
|
can help you out.
