- set desiredRate of peers to 10MB/s instead of 1MB/s
- maximum number of active chunks per peer is now 20 (that was a serious limiting factor)
- ticks that bring no data are not accounted for in the speed estimate anymore. The data is averaged over all ticks since the previous
non zero data chunk -> this brings much more stability to sources and removes lots of oscillation.
The maximum theoretical speed per source peer is therefore 13MB/s (in "Average" DL mode), whereas previously it was 1.3MB/s

a transfer not finish if the original surce for a crc is not here anymore.
If you have a unfinished transfer do a force-check after restart to get back chunks that
where still on verificaiton stage.

- unchecked chunks are not made available to swarming sources, not saved as done.
- force check now uses the simple method to put all chunks in checking mode
- force checked files can be cancelled (finally!)
- improved display (use red for active chunks, yellow for checking)
- cache file are not using chunk checking (assume_availability=true)
The code still contains the #ifdef. It should be removed soon if everything works ok.

Validated chunks are shared to other peers. Force check is now very simple since it just turns all chunks into "needs checking" mode
and sums are asked to sources. Sources maintain a temporary cache of chunks. Since sums are requested sparsely, this should not
affect the sources in terms of performance. We can still imagine precomputing and saving sha1 of chunks while hashing them.
For backward compatibility reasons, the following has been setup *temporarily* in this version:
- unvalidated chunks are still considered as already obtained, and are shared and saved
- force check has been disabled
- final file check is maintained
- in case of file fail, the old checking mode will be used.
All changes for next version are kept in the define 'USE_NEW_CHUNK_CHECKING_CODE' that will be made the default in a few weeks.
At start, I expect most chunk to stya yellow during download, until most sources are able to provide chunk hashs.

- corrected 2 potential flaws of swarming causing request of unavailable data (This should normally be taken care of on the server side!)
- improved swarming test code with fault simulation
- only ask CRC32 maps to peers that have a complete file.

- FT_TM_DOWNLOAD_TIMEOUT: 10 -> 20 secs (RTT limit of 10 secs is too low -> transfers in long tunnels kept switching between active and inactive)
- INACTIVE_CHUNKS_CHECK_DELAY: 60 -> 240 secs (Chunks are kept longer before beign cancelled, which is now affordable)
- MAX_TIME_INACTIVE_REQUEUED: 60 -> 120 secs.(Transfers a kept longer before being re-prioritized in queue)

- removed dependency of mRateIncrease into measured rtt -> would cause very slow transfers through long tunnels

- servers now compute the map in a separate thread
- CRC32Maps are kept in cache for 30 mins
- CRC32Maps requests cannot be used to overflood a server anymore since their number is limited.
- Transfer modules now send keep alive packets to maintain tunnels when asking for a CRC32Map

- added a lock into ftTransferModule::recvFileData() (Crash reported by Costa due to storing data in a deleted transfer module)
- changed names of functions in ftTransferModules to locked_* when appropriate (helps debugging)

You can enable the debugging of the waiting time for a lock of RsMutex in rsthreads.h with
#define RSMUTEX_DEBUG 300
That means all locks waiting longer than 300ms are logged into the stderr.

Major changes are:
* Improvements to tcponudp library to allow multiple UdpStacks / ports, with alternative recievers.
* Resurrected the UdpStunner code, and improved it.
* Added UdpRelay code.
* Modified startup code and ssludp code to use the new tcponudp and add a stunner.
* fixed buggy rs_inet_ntoa
* fixed a bunch of apple gcc warnings. mainly for(;;); => for(;;) ;
These changes shouldn't affect libretroshare stability... those changes will follow!

- changed the order of check in tick() to allow cancelling a file that is being checked
- removed the hash step from mutex protection

Committing these so others can run tests.
Most of these changes will be removed once the problem is fixed!
* Fixed formatting of various serialiser item::print() fns.
* Disabled printout of TlvBinaryData - data.
* added AccurateTimeString() function to util/rsprint.cc
* print serialise / deserialise of FileRequest & FileData + Timestamps.
* added print + timestamp in ftFileProvider::getFileData()
* #define TRANSFER_DEBUG to isolate these changes.
* enabled debugging in fttransfermodule.cc

libretroshare/src/retroshare/
All the relevant headers have been modified to reflect that change.
This allows installation of libretroshare on a system, headers will
be put in $WHEREVER/retroshare/ and we keep the ability to compile
against them, be it on the system or in the SVN tree.

- replaced the findItems() call into a hand-written search (this was causing a rare bug in displaying downloads)

- by the right-click+Force Check on files.
- when a global hash on a downloaded file does not match the announced hash.
When a CRC map check is ordered, the CRC map is requested to one of the sources for the current file download.
When received, all downloaded chunks are checked w.r.t the reference CRC and marked as not done if the CRCs do not match.
The exchange of CRC32 map and requests has been tested, as well as CRC map checking during download (force check).
To be implemented soon:
- caching of CRC32 maps (although these are fast to compute)
- CRC32 map packets for normal downloads. For now these work only for turtle tunnels.
- handling of errors if the CRC never comes. For now, the download will stay stuck in "Checking..." mode.
So, don't play too much with the force check feature for now...

* Added thread-safe rs_inet_ntoa function (util/rsnet.cc)
* Switched all calls to this function (most of the changes)
* Modified getLocalInterfaces() and getPreferredInterface() to avoid string conversions.
- NB: Modified windows functions too, but unable to test (hope it compiles!)
Also:
* Added EVP_CIPHER_CTX_rand_key() replacement function for old versions of SSL (pre 0.9.8) (for OSX 10.5)
- NB: This code should be reworked to remove these calls anyway.
* Updated tests/pqi to handle above changes.

.
- corrected a bug that caused file copy error: a closeFile() was missing when the file is complete. Because of delays in fwrite, the file would not be always co
mplete, nor exist at all for small files (e.g. cache files), which in the later case caused the copy error.
Warning: needs a make clean in libretroshare to recompile.
git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@3261 b45a01b8-16f6-495d-af2f-9b41ad6348cc
- exchange of chunk availability maps from different peers
- correct handling of what is available to which source before asking the data
- correct display of chunks in the progress bars
- generalised the use of compressed chunk maps
- removed the size parameters from the hash search functions
- In addition:
- suppressed a number of per-value transfers of std::string
- improved the FileTransferInfo Widget, to show some additional info
Still to be done:
- chunk map exchange for non anonymous traffic (easy)
- improve accuracy of completion for uploads (for now it's a integer number of chunks)
- check compilation on windows
git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@1993 b45a01b8-16f6-495d-af2f-9b41ad6348cc
- a given chunk strategy
- the availablility map of each source
- Integrated this into ftFileCreator
- added gui menu in file transfer+right click to change the chunk strategy: streaming vs. random
Next step:
- loading/saving file downloading state and availability map
- displaying chunk details in the selected transfer tab (e.g. list of currently worked chunks, and their current downloading completion)
