eMule 0.26d Maella v2.01

Hi,

Here it is the final version for the v0.26d serie.

The five main specific points of this mod are:
- Low CPU load
- 56k modem user friendly
- Full bandwith control (data + control)
- Enhanced upload control for a lower ping
- ...and stability (I hope)

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.

10. [patch] -MTU Configuration-

The MTU can not be configured with the preferences.(See http://www.hms.com)

11. [patch] -Defeat 0-filled Part Senders- (Idea of xrmb)

Check if a received packet is not a fake. A packet and the source are rejected in two conditions:
- A packet is filled with the same pattern (e.g. only with zero)
- The compression factor is too high (>5x) for this kind of file (e.g. zip, rar, ace, mp3, ogg, jpg).
With some kind of file "*.nrg", it could be necessary to disabled this test in preferences.

12. [patch] -AntiCrash/AntiFake handling- (Vorlost/Mortillo)

Check the name of an Hello packet to avoid a crash.

13. [patch] -MiniDump/CrashRpt-

The CrashRpt.dll is OPTIONAL and may work only with XP.
Its purpose is to generate a Minidump file (< 50kB) during a crash.
This Minidump could be then used with the emule.pdb (generated during compilation) to locate the faulty line of code.
To use this dll, it must be first copied in the same directory als eMule.exe.
For details see (http://www.codeproject.com/debug/crash_report.asp).
