Dear all,

I see that it's difficult to work jointly on the 7.0 and the 6.2.

Here's what we'll do to ease the release of these two versions:

- 7.0: Reminder: the aim of this trunk is to transform existing, working 
code to make it maintainable and testable. Consequently, Guillaume is 
free to modify anything in this code to reach this goal. If that means 
removing dependencies with config, it's okay. If that means changing 
whatever code we had before, it's okay. Let's be humble, we work with 
perl, there's more than one way to do it. Sure, it can lead to problem, 
but there is no urgency in the 7.0 release so we can cope with whatever 
problems it could raise LATER. Once the code is good, we'll start 
working on it again. So here are the guidelines to commit to the trunk 
until further notice:
     - only bug fixes
     - no new dependencies. if some bug fixes need them, we can just 
keep them in mind and find a way to solve them later with the new code.
     - of course, remarks on the changes are still welcomed but no 
flamewar. I'll answer remarks first.
this way, we keep the trunk reasonnably in sync with 6.2

On this point (7.0) I'll defer my comments: I wish to hear
Guillaume's intension at first.

OK.

- 6.2: I want it out as soon as possible. Otherwise, Sympa may die. 
that's as simple as this. If I can't say by the beginning of October 
that we finally issued a beta, my management will cut deep in our Sympa 
ressources. So no new features, no big changes. I'll agree with Soji's 
proposal about bulk spool if he makes a strong argument about it.

You said 6.2 would be released "in two weeks".  Just a kidding!
It is impossible even if you were Jacques Anquetil!

Ah Jacques anquetil... We never had such a good cyclist in France - at least without drugs.
I was speaking about 6.2 beta, obviously, not 6.2 stable.

I'll answer about your scenarios later, however I have a few questions popping about moving bulk spool to filesystem:

- do you intend to move both tables (bulkspool and bulkmailer) or only bulkspool?
- how will you handle the metadata attached to mails?
- how will you handle message priority and packets priority, as well as delivery time and such?
- if you move bulkmailer, don't you fear to have difficulties with the readdir necessary to parse the bulk? Sometimes, you can have tens of thousands of packets awaiting distribution. That implies a long readdir.

Maybe you could keep tables just for metadata and keep only receipients and messages on the filesystem.

Well, just so we're clear about advantages / disadvantages of moving spools.

Cheers,

David

However, it is not always impossible.  I'll show three options.

1. (Heavy)

- Test Sympa seriously.
  That is, we'll test most cases including which are not listed in
  matrix: task_manager, WWSympa, SOAP and lacking workflows (e.g.
  workflows regarding listmaster has never been tested).
  Test needs long time.
  * Cut-off: 2014-10-31 (hopefully).

- Release Sympa 6.2b.1.
  First beta test period for one month
  * Cut-off: 2014-11-30 (hopefully)
  Additional time to fix codes for one week
  * Cut-off: 2014-12-07 (hopefully).

- If serious problems won't be found, release Sympa-6.2.

2. (Middle)

- Test Sympa according to current test matrix.
  That is, we might not be able to kill any hidden bugs.
  Test needs midst time.
  * Cut-off: 2014-10-15 (probably)

- Release Sympa 6.2b.1.
  First beta test period for one month
  * Cut-off: 2014-11-15.
  Additional time to fix codes for one week
  * Cut-off: 2014-11-22.

- Release Sympa 6.2b.2.
  First beta test period for one month
  * Cut-off: 2014-12-22.
  Additional time to fix codes for one week
  * Cut-off: 2014-12-29.

- If serious problems won't be found, release Sympa-6.2.

2. (Light)

- Never test Sympa anymore and release recent code as beta.
  That is, we can not be able to kill all evident bugs.
  Test needs no time.
  * Cut-off: 2014-09-15 (surely)

- Release Sympa 6.2b.1.
  First beta test period for one month
  * Cut-off: 2014-10-15.
  Additional time to fix codes for one week
  * Cut-off: 2014-10-22.

- Release Sympa 6.2b.2.
  First beta test period for one month
  * Cut-off: 2014-11-22.
  Additional time to fix codes for one week
  * Cut-off: 2014-11-29.

- Release Sympa 6.2b.3.
  First beta test period for one month
  * Cut-off: 2014-12-29.
  Additional time to fix codes for one week
  * Cut-off: 2015-01-05.

- Release Sympa 6.2b.N.

- ...

- Finally, when serious problems won't be found anymore, release
  Sympa-6.2.

I prefer to option 2 (middle).  David's prefernce seems 3 (light)
for me --- right?

                                *

About bulk spool: The work has been mostly done.  Now bulk*_table
tables are used only to keep each message and most items of tables
were incorporated in attributes (X-Sympa-* pseudo-headers).

Anyhow, please see the running code!  Switching will be finalized by
just a few commits, and I'll (sorry for repeating) do it.

                                *

I'll comment to remainder of your post in other days.

Regards,

In addition to this mail:
- 7.1: we can make a lot of things in this versions, so we'll have to 
chose. Here's a list of proposed features, feel free to complete it:
     - switch config formalism to either JSON or YAML
     - full config editable through the web interface
     - Sympa distribution over several servers
     - full access to all features through all interfaces: command line, 
mail, web, SOAP and REST,
     - internationalized email addresses (RFC 5983)
     - RFC 6729 (mail management tracability)
     - multi medium information brodacasting: transfer messages through 
mail, SMS, web services, etc.
     - multiple email adresses support

Well, that's it. Do we agree about it?

Best regards,

David
