Paging @randy-waterhouse and @domob1812 |
Thanks a lot for finishing this work - this will be great once launched! I'll take a look at the code now - and am already sorry for probably a lot of pedantic comments I'll have. ;) BTW, in the future, I think you should try to have fewer (or just one) commit in a PR - |
I know it's annoying to go through a million commits. I can squash it before we merge, if that's OK. Thanks for looking. |

If I understand your code correctly, you need this here rather than just in the UI code because it is part of the wallet, right? In that case, however, it should also be stored in the wallet and not in a global variable -- especially in light of the recent upstream changes to support multiple wallets in a single running client.

For this one, what do you think about this refactor strategy:
- move
pendingNameFirstUpdate
map to walletdb - move reads, writes, exists checks on
pendingNameFirstUpdate
to methods in walletdb - in the UI do the interaction through walletmodel (QT model) which wraps function calls to walletdb

Yes, basically. I think you should add the variable to CWallet
, where for instance also mapWallet
is (since it is very similar in spirit, IMHO). Access should be through CWallet
, not walletdb, though. (The walletdb is the backing BDB, but from there you load it into memory just like you do now - except that you keep it in CWallet
and ideally do all access to it through the wallet. Do not access walletdb directly, let the wallet do it; at least that's how I think it works for transactions.)
I don't know how the UI typically interacts with the wallet, but I guess walletmodel is the correct way, yes. (In general, I think you should just follow how the wallet transactions are stored and handled, for instance.)

Why do you need this change? I've not yet finished reading your code, but my guess is that you want an "allow empty" address field for name updates - is that correct, or do you need it for something else? (Apart from that, though, I have no idea how this could be related to adding the name UI.) Please briefly explain here for my understanding. Thanks!

This has me wonder about the serialisation of NameNewReturn
. You could actually define "proper" serialisation of the struct in the same way that other stuff in the code is serialised (e. g., transactions). That would fit better into the existing code here than using JSON.

Bonus points: Can you also add a unit test for the auto-updating logic? That would be even better to have, I think -- but may be complicated to write (I don't know how unit testing in Qt works).

Writing Qt unit tests is pretty complicated, but it's been on my list for a while now. I tried a while back but couldn't get it to work correctly basing from the existing Qt tests. I'll definitely give it another stab, though.

Yes, I agree. That's certainly not required for merging this IMHO - but if you do find time to work on it later, it would be much appreciated! (And I feel your pain in writing the Qt tests!)
I would prefer to squash the commits if you don't mind -- but I'm also fine with keeping it as it is, if that would be a lot of extra work and complication for you. (Just wanted to point this out for the future.) |

Thanks for the updates! Please let me know when you are ready for a second round of review - and please note that I'll be busy the next couple of weekends, so I can't promise how much time I'll have for Namecoin-related work. But I should probably also be able to do a follow-up review in a couple of evenings during the week. |

Alright. I've worked through all your comments @domob1812 and made lots of improvements. Your review comments were extremely helpful, so thanks for going through everything. Let me know if you get a chance to go through my revisions. One thing I noticed is that the first test (https://travis-ci.org/namecoin/namecoin-core/jobs/295544697) seems to always fail in Travis, but it succeeds local. Something about not being able to find certain Namecoin commands? I've fixed all the other test issues, though. Maybe @JeremyRand knows more about this? |
Thanks, I'll take another look - although I won't have time until next Monday to do so, unfortunately. In the meantime, @JeremyRand and others: feel free to take a look also, and to test. |

I've added a few more comments, but now everything are just minor things - no bigger refactorings as last time. Thanks for all your work on this!
(But note again that I've not reviewed the Qt-specific stuff too closely, as I don't know much about it anyway. This is particularly true about the .ui files.)

If I understand the code correctly, you are actually storing the address in its string representation in the vchType
. Similarly for hex and rand, which are stored as hex strings, right?
I think since you have this wrapper class and already need to convert between string
and vchType
, you should actually encode the data properly: The address can be a CScript
, and hex/rand can be the actual binary data in vchType
, not the hex string.

I'm down to this last one before I start doing more testing, but I'm a little confused. Do you want me to not return std::string
and instead return standard internal types like CScript
etc? Or are you saying I can leave it accepting/returning std::string
but encode internally and serialize to the reference types (CScript
, etc)?

I've got it working the first way, accepting/returning std::string
but serializing toAddress, txid, rand to CScript
, uint256
, uint160
respectively. If you had something different in mind, let me know. For the way the UI code is using the wallet, it's easier for me to just use strings and it allows me to not have to mess with internal types in the Qt code. But I can change if required.

Thanks! Yes, that's exactly what I meant - storing and serialising as raw data. Interfacing to the UI as strings is certainly fine.

Do you really need a reference_wrapper<string>
here? I think just having a vector<string>
would make the code simpler and easier to read, besides avoiding any potential issues with references to strings that go out of scope. Of course, a vector of references is smaller and faster, but is that really important here vs code simplicity and clarity?

@domob1812 We are almost at the 1 week mark here. Things were unexpectedly productive: not only did we get the name_list GUI merged, but the name renewal GUI is ready for review too. If a 2nd week of dev on this front is approved, I plan to focus on the Renew Name button (should be easy), the name_update GUI, and perhaps porting some UX improvements from Electrum-NMC (e.g. friendlier representations of names), and maybe fix the GUI bugs that currently occur with non-ASCII names/values (they're currently hidden from the GUI completely). |

befa241 Namecoin / Qt: Add name_firstupdate GUI (Jeremy Rand) Pull request description: This PR adds a GUI for `name_firstupdate`, based on Brandon's port of Mikhail's GUI. AFAICT, once #436 is merged, patching this GUI to use `name_autoregister` instead should be roughly a one-liner. Until then, it's still a UX improvement over the status quo, even though the user needs to run `name_new` themselves. Refs #187 ACKs for top commit: domob1812: ACK befa241. Tree-SHA512: 044e2daf0b67992013703fe3e4e6fe255585fa0268b5b084a92c6eff0027f662891adb9633b1a4c1fef7a39de2e796b8aa713b0f901558ce016a00318e5b602a
I've finally completed the merge to namecoin-core/master. I had to refactor several things, due to upstream changed in the internal APIs, so there may be some bugs that didn't exist in the previous version. I also fixed the following bugs:
I know domob said he had some stylistic critiques, so I'd like to work through some of those as well once I know what they are.
