eMule 0.26d Maella v2.0 beta4

Hi,

I would like to thanks MickyMax. He managed to find me a new host.
A mirroring will be still available by Dr.Slump but with a small delay.

The beta4 fixes a bug, that could crash the client.

General
----------

1. [FAF] -Allow Bandwidth Settings in <1KB Incremements-

For the users of analog modem (e.g. 56k), the bandwidth can be set with an increment of 0.1 [KB/s].

2. [patch] -Small latency-

The basic perdiod has been reduce from 100 ms to 50 ms.
This lower period help to have a better control of the bandwidth.

3. [patch] -New bandwidth control-

Both the controls for the upload and download datarate have been fully rewritten.
It should allow a smoother use of the bandwidth resources and a lower ping.
It corrects the bug of the Patch#5 (v0.26c only) that avoid a user to change its setting to a unlimitted download.
Attention: the upload limit should not be set to 'unlimited'

4. [patch] -Accurate measure of bandwidth: IP, TCP or UDP, eDonkey protocol, etc-

The complet measure of the bandwidth has been rewritten.
The computing of the bandwidth is proceed only once per second.
It should be much more accurate (almost real-time, average value for the last 2 seconds) and use less CPU time (based Ottavio84).
The overhead includes the IP overhead (partially), TCP and UDP overhead, eDonkey overhead + control. The measure is done at the Socket's interface.
New curves have been added to the graphics to display the 'Overall-current', 'Current', 'Average-minute' and 'Average-session' datarate.

5. [patch] -New Save/load Sources- enkeyDEV(Ottavio84)

This patch saves 10 sources per downloaded file.
The sources have an expiration of 3 days.
The sources are saved in the .txtsrc files, that are text and so human-readable.

6. [patch] -Enable/Disable source exchange in preference- (Tarod)

Now when Disable Exchanging Sources is active sources are not sent nor asked.
Users with a low bandwidth should better let the exchange source disabled.

7. [patch] -Overhead compensation (pseudo full rate control)-

This is the most experimental part of this mode.
It could be enabled/disabled in the preference.
When activated, the upload/downloads limits applied to the full bandwidth (data + overhead).
The upload/download control tries to compensate the measured overhead.

8. [patch] -General Code Improvement-

Divers code improvement to reduce the cpu load. Most of these changes have been reported in the Forum of the emule project

9. [fix] -Downloadlistctrl-

Fix a bug of the official release 'Sources are sometimes not displayed or displayed under the wrong file'.
This fix is still experimental.


Known bug
--------------

Upload limit should not be set to 'unlimited'


To do
------

- Add support for 'Unlimited' upload
- Change the management of the upload slot
- Search and improve the hot spots to reduce the CPU load
- Clean-up this change-log...
