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

AcidD

Can someone fork Bitcoin into the Feathercoin Github ?

@Wrapper you made a fair point a while back somewhere…if we properly fork from Bitcoin head and then do our commits we can easily pull in their fixes as well ?

wrapper

@AcidD Yes, thats the job I call “Going to Head” !

Getting this message opening the debug.log in 0.11.2

The file /home/tony/.feathercoin/debug.log was opened with UTF-8 encoding but contained invalid characters.
It is set to read-only mode, as saving might destroy its content.
Either reopen the file with the correct encoding chosen or enable the read-write mode again in the tools menu to be able to edit it.

When writing to the Debug log, does 0.11.2 leave comments that are written by @lizhi and therefore uses a different character encoding?

Issue Notes :

Whilst syncing a (fresh blockchain database/wallet) Feathercoin 0.11.2-dev , mouse over the exclamation mark next to Balances . says Bitcoin

QRCodes did not work - need review after merge complete

Check : Transaction fee set to 0.00001 FTC/kB

Sign message - tool tip on Advanced menu option - Verify message sign message tab says bitcoin

Verify message - tool tip on Advanced menu option - Verify message - Verify message tab says bitcoin

Advanced / Options / Wallet : Check default coin control settings are correct

There are quite a few changes made to the wallet structure, the standard bitcoin connection animation looks Ok. opennames is missing.

@AFB helped to do some fiddling to bring in all the improvements we did into 0.11.2 , possibly make a couple more icons / update some bad new forms.

There is another test (that would help us move to head) - Fork Bitcoin, checkout 0.11 last version - merge ftc 0.11.2

Update autoconfig.sh to test for zxing Directory e.g. :
if [ ! -d “$DIRECTORY” ]; then
# Control will enter here if $DIRECTORY doesn’t exist.
fi

Update Re-Indexing message to be more friendly / informative? (when you upgrade)

Why do we have uFTC and mFTC surely DecaFTC is more logical?? (needs review)

Test and document Smart contracts.

Smart contracts is just a form, review and remove, smart contract form.

SX search for stealth coins not included.

find not utf-8 characters grep -axv ‘.*’ main.cpp

propose launch option shrink debug file :

Add -shrinkdebuglog to the options you use to start feathercoin, or add shrinkdebuglog=1 to your feathercoin.conf. Every startup, if the log is larger than 1MB, it will shrink it to 200KB.

wallet.cpp change control :
// TODO: fix handling of ‘change’ outputs. The assumption is that any
// payment to a script that is ours, but is not in the address book
// is change. That assumption is likely to break when we implement multisignature
// wallets that return change back into a multi-signature-protected address;
// a better way of identifying which outputs are ‘the send’ and which are
// ‘the change’ will need to be implemented (maybe extend CWalletTx to remember
// which output, if any, was change).

@wrapper we should group these notes and create issues directly on github.
Otherwise it is duplicated work

wrapper

I agree, I’ll move them to issues, these are notes while I investigate.

I’ve also created a pull list on Github so we can discuse which and how we pull the missing commits from 0.9.6.2 and, opennames. We can use the experience to to pull in further changes from head.

https://github.com/FeatherCoin/Feathercoin/pull/201

The pull can be used to identify which don’t need or need more icons etc as we agreed, the project will be used to document pulling them in.

Need to use cherry pick and meld.

~~Try git imerge a try: that will apply your commits one by one, giving you the chance to do a rebase incrementally (meaning you can start a rebase, interrupt it, resume it later!).~~

You can see here a comparison between Incremental merge vs. direct merge vs. rebase :

Testing 0.11.2 re-indexing database after it was viewed by 0.9.6.1

Crashed twice with : /feathercoin-qt Segmentation fault

seems to have carried on after restart. tbc

Wellenreiter

@wrapper check the build-aux/m4/ax_boost-base for the version.
it is 1.58 in bitcoin code, 1.54 should be ok, too, but I’ve set it to >1.20 to support older OS. We may have to increase that back to >= 1.54

wrapper

I’m setting up a test environment. I’ll repeat the test (viewing 0.11 database with 0.9.6.2) after I’ve resynced and, this time, saved uncorrupted / synced 0.11.2 database

Merging commits from 0.9.6.2 to 0.11.2 procedure

Install a mergetool. On Linux, meld:

sudo apt-get install meld

Configure your mergetool:

git config --global merge.tool meld

Then, iterate in the following way:

git cherry-pick ....
git mergetool
git cherry-pick --continue

wrapper

First 0.9.6.2 mergeTest cherry pick commit :

https://github.com/FeatherCoin/Feathercoin/pull/201/commits/0ba808af8a10c8231490088932baa2d6ae0c7106
Added man pages for feathercoin, modified icons

  error: cherry-pick is not possible because you have unmerged files.
  hint: Fix them up in the work tree, and then use 'git add/rm <file>'

git mergetool
Merging:
contrib/debian/manpages/feathercoin.conf.5

contrib/debian/manpages/feathercoin-qt.1

Deleted merge conflict for 'contrib/debian/manpages/feathercoin.conf.5':
  {local}: deleted
  {remote}: created file
Use (c)reated or (d)eleted file, or (a)bort?

Note
Test - Create © all new MAN files. were MAN pages moved in from Bitcoin 0.11? and then FTCed? should still work.
Are there any other references / links to the original MAN names?

I have seen that several times dunig my tests with 0.9.6.* . The ORPHAN BLOCK COUNTER going up to
ProcessBlock() ProcessBlock: ORPHAN BLOCK 751.

It seems there was a number of forks happening, which where resolved later. I can’t remember the block height where it happened, so I can’t tell, that is is the same block where the messages started to show up
