Core migration issues:
0️⃣ Who is here today? Did you learn something, or get encouragement from someone, working on a d.o issue?
| quietone | Vicki,. Yes, benjifisher continues to teach me patience and attention to detail. |
| benjifisher | Benji: like Vicki, one of the co-maintainers of the migration subsystem. I appreciate Vicki's comment here: #2796755: [PP-1] Deprecate Migration::set()#comment-13959040 @benjifisher, good on you for complimenting yourself!(edited) |
| mikelutz (he/him) | hi all (edited) |
| Matroskeen | :wave: Ivan from Ukraine. I got a couple of RTBC’s from @quietone today, it is pretty encouraging :raised_hands: |
| dinarcon | Hello everyone :wave: |
1️⃣ What should we talk about today? Suggest topics here and I will add threads. I will also check for comments on the issue for today's meeting.
| quietone | #2845340: migrate mapping & messages table names are truncated, can lead to incorrect mapping lookups |
| quietone | #2456259: [META] Drupal 7 to Drupal 8 Migration path |
| quietone | #3039240: Create a way to declare a plugin as deprecated |
| dinarcon | It would be nice to have a way to disable hook execution during a migration. There is some work on https://www.drupal.org/sandbox/onkeltem/2828817 Either helping in promoting to a full project or bringing the functionality to core would be great. |
2️⃣ Action items. To be added later.
| benjifisher | Looking at last week's action items, I think we have made progress on most of those issues, but I will copy them here so that we can keep track. |
| benjifisher | Fixed: #3150733: Drupal 9 compatibility fixes for Commerce Migrate |
| benjifisher | See 5️⃣ #3143486: Invalid migrations being ignored by the migrate process plugin: migration_lookup |
| benjifisher | No progress (See 6️⃣): https://gitlab.com/drupalspoons/migrate_tools/-/issues/118 :disappointed: (edited) |
| benjifisher | RTBC: #3189587: Add documentation for taxonomy terms source plugins |
| benjifisher | Progress, currently NW: #3069776: SQL source plugins: allow defining conditions and join in migration yml |
| benjifisher | Progress, currently NR: #3063856: Add ability to view migrate_message table data |
3️⃣ Statistics
| benjifisher | Fixed since last week's meeting: 5 (not counting the issue for the meeting). |
| benjifisher | RTBC: 6, including 2 Major and 2 that have been waiting more than a month. (One issue is in both categories.) |
| benjifisher | NR: 27, including 7 that have been waiting more than a month and 4 Major |
| benjifisher | That represents a lot of progress since last week. |
4️⃣ How can I help? Comment in this thread if you are looking for ways to help. Give us some idea of what you would like to do: documentation, code review, testing, project management, ...
| quietone | no discussion |
5️⃣ Invalid migrations being ignored by the migrate process plugin: migration_lookup
| benjifisher | #3143486: Invalid migrations being ignored by the migrate process plugin: migration_lookup |
| benjifisher | Is this a duplicate of #2744323: MigrationPluginManager::createInstance() doesn't throw an exception when failing to create an instance? If so, should we close one as a duplicate? Should the remaining issue be Major? |
| benjifisher | @quietone, you are the one who marked the newer issue as NR and linked to a few other issues. Do you think we should make this one a meta for all the related issues> |
| quietone | Good idea. I can do that. |
| quietone | New meta, #3192870: [Meta] What to do when a migration can not be created |
6️⃣ Update Migrate Tools for Drush 10.4
| benjifisher | https://gitlab.com/drupalspoons/migrate_tools/-/issues/118 |
| benjifisher | I wanted to work on this issue, but have not yet started. |
7️⃣ Should we make a new community initiative for migration? (edited)
| benjifisher | We discussed this at last week's meeting (#3189805: [meeting] Migrate Meeting 2021-01-07). @mikelutz (he/him), any opinion? |
| quietone | +1. I like the idea of Drupal 9 compatibility (for a defined set of modules) as being a goal. |
| mikelutz (he/him) | I mean it's basically semantics, isn't it? We wouldn't be changing what we are doing. |
| benjifisher | Also advertising. We would get listed on https://www.drupal.org/community-initiatives. |
| quietone | And if I were an admin/dev out there, particularly one just getting started with migrate, I would be glad the initiative exists. It lets me know that the community knows this is a challenging task and are actively working on it. |
| mikelutz (he/him) | Alright, well let's phrase it like "should we make a new community initiative for migrate" not, "reopen the migrate initiative" because the old core initiative is a completely different thing than a community initiative. |
| benjifisher | I can edit that ... |
| Matroskeen | I like the idea. Although the Migrate API is great, there is still plenty of stuff to do |
| mikelutz (he/him) | My gut reaction to "should we reopen" was hell no. We put way to much work in to finish it, lol |
8️⃣ migrate mapping & messages table names are truncated, can lead to incorrect mapping lookups
| benjifisher | #2845340: migrate mapping & messages table names are truncated, can lead to incorrect mapping lookups |
| benjifisher | The remaining question for that issue is how toHandle the change of migrate table names in a BC friendly wayI think we need an update function toLoop through all migration plugins;Calculate the table names under the old and new systems.When different, update the table name.Is that last step possible or do we have to create, copy, and delete? |
| quietone | Thanks. That is exactly what I wanted confirmation on, that the update hook is needed. I am not sure about the last step either but I will soon. |
| benjifisher | https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Database%... |
| benjifisher | And https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Database%... to get a Schema object. |
| benjifisher | Completely untested by me. :wink: |
9️⃣ [META] Drupal 7 to Drupal 8 Migration path
| benjifisher | #2456259: [META] Drupal 7 to Drupal 8 Migration path |
| quietone | These are remaining issues to complete the D7 migration path. Two of the three are at NR. |
| quietone | Can anyone review those issues? |
| benjifisher | #2814953 was originally RTBC in Comment #59. Since then, there have been a few re-rolls, and I have reviewed those. I should be able to review the latest one. |
| benjifisher | The other one is #3051252: Upgrade path for Multiupload Filefield Widget and Multiupload Imagefield Widget. I have not looked at it. Any volunteers? |
1️⃣0️⃣ Create a way to declare a plugin as deprecated
| benjifisher | #3039240: Create a way to declare a plugin as deprecated |
| benjifisher | @quietone, your latest comment on the issue in 8️⃣ is that we do not need to postpone it on this issue.I guess we need to resolve this before we can start thinking about removing the D6 source plugins. |
| quietone | Yes, and this is not part of #3118154: [meta] Deprecate dependencies, libraries, modules, and themes that will be removed from Drupal 10 core by 9.4.0-beta1 which is to do the deprecations by 9.2.0-beta1 |
| quietone | In other words, it needs more people working on it. |
| benjifisher | 9.2.0-beta1 is scheduled for mid May. I guess that is the deadline for deprecating anything to be removed in Drupal 10. |
1️⃣1️⃣ Migrate booster
| benjifisher | https://www.drupal.org/sandbox/onkeltem/2828817 |
| benjifisher | Sandbox project. |
| dinarcon | A similar feature was available in migrate core in Drupal 7. Does it make sense to bring this to core? |
1️⃣2️⃣ Wrap up
| benjifisher | Thanks for participating! I will update 2️⃣. Please continue to add comments in the threads. In 1-7 days, we will post a transcript for today's meeting. |
| quietone | @benjifisher, thank you for facilitating! |
