[Dev] Feathercoin 0.9.6.2 * Maintenance fix, build & upgrade issues notes.

AcidD

@Wellenreiter and I have been working on the sendAlert call which is used to send alerts across the Feathercoin Network.

I Believe we’ve solved this. Wellenreiter was able to send an alert over the TestNet and he received it on his node.

There was an issue with one of the blocks on the testnet so that’s just being fixed…one that’s done I should hopefully be able to connect to the TestNet Node Wellenreiter set up and receive his test message.

Then we can apply the same patch to prod. :)

Just a note to double check FTC code for this issue LTC #293 - List of FTC custom settings?

https://github.com/litecoin-project/litecoin/blob/master/src/main.cpp#L4161

main.cpp nCheckDepth #293

In the code it says
nCheckDepth = 1000000000; // suffices until the year 19000

But Litecoin is 4x faster then Bitcoin.
The note should say “until the year 4750”

or should the nCheckDepth be changed into 4000000000 s

Release of New Feathercoin Wallet version 0.9.6.1

@Wellenreiter has started to lock down the code for the release of version 0.9.6.1.

Reviewed outstanding document updates and policy.

The FTC software settings, naming conventions and software development fork procedure showed that a lot of work is need to up keep Feathercoin name interface changes. Some changes such as comments, or where Feathercoin operates the same as Bitcoin core are unnecessary. How to handle files in the future for cherry pick or updates from head were discussed.

 /doc
 /doc/release-notes

ToDo :

Include Feathercoin 0.9.6.1 release notes
Create Beta test builds / Window / MAC etc
~~Review - update Wallet guide, MultiSig is an important, but complex update, needs better screen shots / help text.~~
https://github.com/wrapperband/FeathercoinWalletGuide#multisig-button
* Review / consider - Include 5, 7 name Multisignature addresses i.e do further update

* Multisig: A beginner’s guide
https://99bitcoins.com/multisig-a-beginners-guide/

Note : 0.9.6.1 will be a long term version, compatible as a wallet with 0.11. The most usefull cases for Multisig, once you have got over the learning curve, is for more names, and say 3 out of 5, so there is redundancy for fund handling or other open source management / DAO criteria.
~~Review wither to including Feathercoin Wallet Guide in release~~

Review wither to including Feathercoin Wallet Guide in release

I’d prefer to just include a link to the online guilde in the wallet-GUI. it gives more flexibility and enables us to update/enhance the guide without releasing new versions of the Wallet

Feathercoin has spent considerable bounties to include shapeshift, for over one year. We understood FTC was to be reinstated after you had some problems.
The next release is to be finalised within 5 days and it will then be about 6 months before it can be reinstated.

Incorrect setting of minimum fee #181
https://github.com/FeatherCoin/Feathercoin/issues/181

In at least one place (in main.cpp) - FTC custom settings are required because of block time and reward scaling of Bitcoin parameters.

Further, whilst reviewing an emergency change, comparison should be made with the Litecoin setting, to ensure the further scaling of coin reward is reflected in the minimum fees.

This is very important as it is currently mode of failure of Bitcoin and we will be stuck with high fees till the next release.

v0.8 https://github.com/FeatherCoin/Feathercoin/blob/master-0.8/src/main.cpp
/** Fees smaller than this (in satoshi) are considered zero fee (for transaction creation) /
int64 CTransaction::nMinTxFee = 2000000;
/* Fees smaller than this (in satoshi) are considered zero fee (for relaying) */
int64 CTransaction::nMinRelayTxFee = 2000000;

v0.9 https://github.com/FeatherCoin/Feathercoin/blob/0.9.6/src/main.cpp
/** Fees smaller than this (in satoshi) are considered zero fee (for transaction creation) /
int64_t CTransaction::nMinTxFee = 1000000; // Override with -mintxfee
/* Fees smaller than this (in satoshi) are considered zero fee (for relaying and mining) */
int64_t CTransaction::nMinRelayTxFee = 1000000;

In 0.8 but not 0.9 main.cpp

// Feathercoin
// To limit dust spam, add nBaseFee for each output less than DUST_SOFT_LIMIT
BOOST_FOREACH(const CTxOut& txout, vout)
if (txout.nValue < DUST_SOFT_LIMIT)
nMinFee += nBaseFee;

// Raise the price as the block approaches full

if (nBlockSize != 1 && nNewBlockSize >= MAX_BLOCK_SIZE_GEN/2)

wrapper

Notes : Minimum fee issue / review

Review src/util.h 0.9.x

 static const int64_t COIN = 100000000;

https://github.com/FeatherCoin/Feathercoin/blob/0.9.6/src/main.h

nBaseFee is the value you configure. In 0.9 default is 1000000

int64_t nMinFee = (1 + (int64_t)nBytes / 1000) * nBaseFee

Review main.cpp main.h 0.8.x

https://github.com/FeatherCoin/Feathercoin/blob/master-0.8/src/main.h

  /** Dust Hard Limit, ignored as wallet inputs (mininput default) */
 static const int64 DUST_HARD_LIMIT = 1000; // 0.00001 FTC mininput

 /** Dust Soft Limit, allowed with additional fee per output */
static const int64 DUST_SOFT_LIMIT = 100000; // 0.001 FTC

Re : How should the FTC fees been set?

LTC was 4 times Faster than BTC, so fee level need to be 1/4 BTC to be proportional.

FTC had 4 times the amount of coins than LTC, so FTC fee need to be 1/16 of BTC value, or 1/4 LTC value.

It looks like LTC settled on 1/10 for ease of calculation and make fees lower than BTC.

In 0.6.x and 0.7.x FTC settled on 1/20 which make our fees slightly less than LTC, and is easier to code.

Our dust level needs to be reduced by same level (which has been done?)

@wrapper said in [Dev] Feathercoin 0.9.6.2 * Maintenance fix & Issues notes for 0.11.2:

Tried : Adding -fPIC to CFAGS in makefile

I’ve modified configure.ac to add -fpic to CXXFLAGS and CFLAGS
The later is required to compile neoscrypt with --disable static --enable shared:

if test x$use_hardening != xno; then
  AX_CHECK_COMPILE_FLAG([-Wstack-protector],  HRDENED_CXXFLAGS="$HARDENED_CXXFLAGS -Wstack-protector"])
  AX_CHECK_COMPILE_FLAG([-fstack-protector-all],[HARDENED_CXXFLAGS="$HARDENED_CXXFLAGS -fstack-protector-all"])
  AX_CHECK_COMPILE_FLAG([-fPIE],[HARDENED_CXXFLAGS="$HARDENED_CXXFLAGS -fPIE"])
  AX_CHECK_COMPILE_FLAG([-fPIC],[HARDENED_CXXFLAGS="$HARDENED_CXXFLAGS -fPIC" && CFLAGS="$CFLAGS -fPIC"])

That way the flags are set only, if the code is hardened.
