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

Wellenreiter

@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

wrapper

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

Merging:

Deleted merge conflict for 'contrib/debian/manpages/feathercoin.conf.5':

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

@wrapper without the ui file you’d get errors during compile, as some signals/slots are missing.
