New Policy Draft
|
|
Version 20070301
|
|
|
|
Intro:
|
|
------
|
|
This document is an attempt to write a new policy as the old is fairly
|
|
confusing and easy to misunderstand, its intention is not really to
|
|
change the rules but rather to write them down clearer ...
|
|
also for simplicity and to prevent flamewars, i would suggest that you
|
|
fork this document and propose that fork as alternative if you have a
|
|
significant disagreement with me on some part
|
|

* MPlayer developer, generally referred to simply as developer in this document
|
|
is any person who has a open (not cracked, not suspended) svn write account
|
|
* MPlayer leader, generally referred to simply as leader in this document, every
|
|
leader is also a developer

C. Code and SVN Rules
|
|
-----------------------------
|
|
Renaming/moving/copying files or contents of files
|
|
Do not move, rename or copy files of which you are not the maintainer without
|
|
discussing it on the public developer mailinglist first!
|
|
|
|
Never copy or move a file by using 'svn delete' and 'svn add'. Always use
|
|
'svn move' or 'svn copy' instead in order to preserve history and minimize
|
|
the size of diffs.
|
|
|
|
To split a file, use 'svn copy' and remove the unneeded lines from each file.
|
|
|
|
Don't do a lot of cut'n'paste from one file to another without a very good
|
|
reason and discuss it on the mplayer-dev-eng mailing list first. It will make
|
|
those changes hard to trace.
|
|
|
|
Such actions are useless and treated as cosmetics in 99% of cases,
|
|
so try to avoid them.
|
|
|
|
Reverting broken commits
|
|
There are 2 ways to reverse a change, they differ significantly in what they
|
|
do to the svn repository
|
|
The recommit old method:
|
|
svn merge
|
|
svn ci <file>
|
|
This simply changes the file(s) back to their old version localy and then
|
|
the change is commited as if it is a new change
|
|
The svn copy method
|
|
svn rm <file>
|
|
svn ci <file>
|
|
svn cp -r<good revision> svn://svn.mplayerhq.hu/mplayer/trunk/[<path>/]<file> <file>
|
|
svn ci <file>
|
|
This simply removes the file and then copies the last good version with
|
|
its history over it, this method can only be used to revert the n last
|
|
commits but not to revert a bad commit in the middle of its history
|
|
Neither method will change the history, checking out an old version will
|
|
always return exactly that revision with all its bugs and features. The
|
|
difference is that with the svn copy method the broken commit will not be
|
|
part of the directly visible history of the revisions after the reversal
|
|
So if the change was completely broken like reindenting a file against the
|
|
maintainers decision, or a change which mixed functional and cosmetic
|
|
changes then it is better if it is not part of the visible history as it
|
|
would make it hard to read, review and would also break svn annotate
|
|
For the example of a change which mixed functional and cosmetic parts they
|
|
should of course be committed again after the reversal but separately, so one
|
|
change with the functional stuff and one with the cosmetics
|
|
OTOH if the change which you want to reverse was simply buggy but not
|
|
totally broken then it should be reversed with svn merge as otherwise
|
|
the fact that the change was bad would be hidden
|
|
One method to decide which reversal method is best is to ask yourself
|
|
if there is any value in seeing the whole bad change and its removal
|
|
in SVN vs just seeing a comment that says what has been reversed while
|
|
the actual change does not clutter the immediately visible history and
|
|
svn annotate.
|
|
If you are even just slightly uncertain how to revert something then ask on
|
|
the mplayer-dev-eng mailing list.
|
|
|
|
Broken code
|
|
You must not commit code which breaks MPlayer! (Meaning unfinished but
|
|
enabled code which breaks compilation or compiles but does not work.)
|
|
You can commit unfinished stuff (for testing etc), but it must be disabled
|
|
(#ifdef etc) by default so it does not interfere with other developers'
|
|
work.
|
|
|
|
Testing code
|
|
You don't have to over-test things. If it works for you, and you think it
|
|
should work for others, too, then commit. If your code has problems
|
|
(portability, exploits compiler bugs, unusual environment etc) they will be
|
|
reported and eventually fixed.
|
|
|
|
Splitting changes
|
|
Do not commit unrelated changes together, split them into self-contained
|
|
pieces. Also dont forget that if part B depends on part A but A doesnt
|
|
depend on B, then A can and should be commited first and seperately from B.
|
|
Keeping changes well split into self contained parts makes reviewing and
|
|
understanding them on svn log at the time of commit and later when
|
|
debugging a bug much easier.
|
|
Also if you have doubt about spliting or not spliting, dont hesitate to
|
|
ask/disscuss it on the developer mailing list.
|
|
|
|
4. Do not change behavior of the program (renaming options etc) or
|
|
remove functionality from the code without approval in a discussion on
|
|
the mplayer-dev-eng mailing list.
|
|
|
|
|
|
5. Do not commit changes to the build system (Makefiles, configure script)
|
|
which change behaviour, defaults etc, without asking first. The same
|
|
applies to compiler warning fixes, trivial looking fixes and to code
|
|
maintained by other developers. We usually have a reason for doing things
|
|
the way we do. Send your changes as patches to the mplayer-dev-eng mailing
|
|
list, and if the code maintainers say OK, you may commit. This does not
|
|
apply to files you wrote and/or maintain.
|
|
|
|
|
|
Cosmetics
|
|
We refuse source indentation and other cosmetic changes if they are mixed
|
|
with functional changes, such commits will be reverted. Every
|
|
developer has his own indentation style, you should not change it. Of course
|
|
if you (re)write something, you can use your own style... (Many projects
|
|
force a given indentation style - we don't.) If you really need to make
|
|
indentation changes (try to avoid this), separate them strictly from real
|
|
changes.
|
|
|
|
NOTE: If you had to put if()@{ .. @} over a large (> 5 lines) chunk of code,
|
|
then either do NOT change the indentation of the inner part within (don't
|
|
move it to the right)! or do so in a separate commit
|
|
|
|
|
|
Commit log message
|
|
Always fill out the commit log message. Describe in a few lines what you
|
|
changed and why. You can refer to mailing list postings if you fix a
|
|
particular bug. Comments such as "fixed!" or "Changed it." are unacceptable.
|
|
|
|
|
|
Applying patches
|
|
If you apply a patch by someone else, include the name and email address in
|
|
the log message. Since the mplayer-cvslog mailing list is publicly
|
|
archived you should add some spam protection to the email address. Send an
|
|
answer to mplayer-dev-eng (or wherever you got the patch from) saying that
|
|
you applied the patch. If the patch contains a documentation change, commit
|
|
that as well; do not leave it to the documentation maintainers.
|
|
|
|
|
|
messing with other developers code
|
|
Do NOT commit to code actively maintained by others without permission. Send
|
|
a patch to mplayer-dev-eng instead.
|
|
|
|
|
|
Subscribe to svnlog
|
|
Subscribe to the mplayer-cvslog mailing list. The diffs of all commits
|
|
are sent there and reviewed by all the other developers. Bugs and possible
|
|
improvements or general questions regarding commits are discussed there. We
|
|
expect you to react if problems with your code are uncovered.
|
|
|
|
|
|
Documentation
|
|
Update the documentation if you change behavior or add features. If you are
|
|
unsure how best to do this, send a patch to mplayer-docs, the documentation
|
|
maintainers will review and commit your stuff.
|
|
|
|
|
|
Controversial changes
|
|
Always send a patch to the mplayer-dev-eng mailing list before committing
|
|
if you suspect that the change is going to be controversial. Based on past
|
|
experience, these changes are likely to be controversial:
|
|
- feature removal, even if obsolete
|
|
- changes to "special" output messages (like the "Core dumped ;)" message)
|
|
- verbosity changes from default (info) level
|
|
- changes to "historical" parts of docs and webpages
|
|
- use of internal or external libraries
|
|
- changes to the internal architecture
|
|
- non trivial changes to very fundamental parts of mplayer
|
|
|
|
|
|
Public discussions
|
|
Try to keep important discussions and requests (also) on the
|
|
mplayer-dev-eng mailing list, so that all developers can benefit from them.
|
|
IRC is good for quick discussions, but nobody is there 24/7.
|
|
also subscribe to the public developer mailing list
|
|
|
|
|
|
Compiler Warning fixes
|
|
Do not change code to hide warnings without ensuring that the underlaying
|
|
logic is correct and thus the warning was inappropriate
|
|
|
|
|
|
Patches
|
|
read and follow patches.txt when sending patches for mplayer
|
|
|
|
|
|
Insults
|
|
Do not insult other people in relation to mplayer on any public mailing
|
|
list, that is calling code from someone else a pile of broken shit is
|
|
perfectly fine but calling the developer herself a retarded f*cking moron
|
|
is not acceptable
|
|
|
|
|
|
Forking
|
|
People disagreeing with the developers or leaders may fork the project,
|
|
the leaders MUST in that case provide a svn dump with all history if
|
|
the person forking wants one
|
|
|
|
|
|
Communicating passwords
|
|
Developers who have provided a public gpg key shall only receive
|
|
passwords or other sensitive information related to mplayer encrypted
|
|
with their gpg key or in another secure way
|
|
|
|
|
|
V. Votes
|
|
--------
|
|
Its inevitable that some things will be decided by voting, votes in the past
|
|
have due to total lack of rules been problematic for example as many people
|
|
rather wrote long texts and voted based on some condition instead of saying
|
|
a clear yes or no, still its important that people can vote based on a
|
|
condition
|
|
The result of a vote is binding for all developers and leaders, though of
|
|
course they can leave the project and thus cease to be a developer or leader
|
|
any time
|
|
|
|
Vs. Starting a vote
|
|
Any single developer can start a vote, to do so she has to send a mail to the
|
|
public developer mailing list of the project with a subject containing [VOTE]
|
|
and a clear and concise description, a longer descrition can be in the body
|
|
of the mail
|
|
|
|
Vp. Proposing an option (point on the ballot, better term?)
|
|
Any single developer can propose an option up to 7 days after a vote has
|
|
been started, to do so she has to reply to the original vote mail on the
|
|
public developer mailing list and clearly, concise and unmistakably describe
|
|
the option and place [VOTE-OPTION] instead of [VOTE] in the subject
|
|
in addition to proposed options, there always exists the default option
|
|
of doing nothing
|
|
options can be conditional on anything which at the end of the vote can
|
|
be clearly and unmistakably be answered with true or false
|
|
|
|
Vv. Voting
|
|
Any developer can cast a vote up to 10 days days after a vote has been
|
|
started, to do so she has to reply to the original vote mail on the
|
|
public developer mailing list and rate options each with an integer
|
|
unrated options shall be counted equal to the default option
|
|
Any leader can cast a veto against any option except the default up to 10 days
|
|
days after a vote has been started, to do so she has to reply to the original
|
|
vote mail on the public developer mailing list and replace
|
|
[VOTE] by [VOTE-VETO]
|
|
Developers and leaders who use gpg/pgp MUST sign their votes and vetoes
|
|
|
|
Vc. Counting votes
|
|
The person starting the vote has to count the votes and vetoes and publish
|
|
the result on the public developer mailing list as reply to the original vote
|
|
with [VOTE-RESULTS] instead of [VOTE] in the subject
|
|
Vcv. Counting vetoes
|
|
if the majority of leaders that is yes >= no && yes>0 cast a veto against an
|
|
option then it has a required supermajority of 2:1 otherwise it has a
|
|
required supermajority of 0:1 and in either case no quorum requirement
|
|
Vcc. the votes shall be counted by using the Condorcet/Clone Proof SSD
|
|
Voting Method described in http://www.debian.org/devel/constitution A.6
|
|
|
|
Reasoning behind avoiding of a quorum and majority requirement except in
|
|
the case of vetoes
|
|
short awnser its stupid and has catastrophical failure modes
|
|
example of one such failure mode, lets assume a 1:1 majority requirement
|
|
as debian uses by default, there are 101 developers who vote, there are
|
|
3 options A,B and D the default (doing nothing / further discussions)
|
|
50 developers prefer A over B and B over discussions (A>B>D)
|
|
50 developers prefer discussions over A and A over B (D>A>B)
|
|
1 developer prefers B over discussions and discussions over A (B>D>A)
|
|
in this case A is approved by 50 of 101 developers and is droped due to
|
|
the lack of majority, B is approved by 51 of 101 developers and is not
|
|
furthermore B wins even though 100 of 101 developers prefer A over B
|
|
|
|
|
|
S. Changes to developer and Leader status
|
|
----------------------------------------
|
|
The majority of leaders, that is yes>no can give and take away
|
|
developer and leader status to people
|
|
furthermore any developer or leader can step back and thus loose
|
|
his leader and or developer status
|
|
People disagreeing with the leaders are free to fork the project
|
|
new developers should be asked for real name, public gpg key, phone
|
|
number and email addresses, none of this is mandatory though, it is asked
|
|
so as to be able to contact the developer if the need arises and one
|
|
contact method fails
|
|
|
|
|
|
O. Violations
|
|
-------------
|
|
Any leader can after at least one leader has warned another developer
|
|
due to breaking policy, suspend his account if he repeats the violation
|
|
Ow. A policy violation warning MUST be CCed to the developer who violated
|
|
the policy
|
|
|
|
|
|
We think our rules are not too hard. If you have comments, contact us.
