Concerns:
- Emergency Reparent Refactor vitessio/vitess#6449 - still has segfault problem if doing an ERS on a shard that has a tablet falsely claiming MASTER status. This is covered in [reparentutil / ERS] confirm at least one replica succeeded to
SetMaster, or fail vitessio/vitess#7486, but incorporating that is a little tricky. Options:
a. expand cherry-picks to includereparentutiland the corresponding bugfix therein
b. backport equivalent fix (don't attempt to wait-for-relay-logs-to-apply on any candidate not instatusMap(because it's actually inmasterStatusMap)) - a

This seems wrong to me... are there no new vtctldclient PRs in here?

Don't believe so -- vitessio#6752 is the only vtctld change in this branch is the one listed as 8.0 in your spreadsheet. This dependency was removed as part of vitessio#6547
I make no claims to correctness only accuracy vs upstream 😓 https://github.com/vitessio/vitess/blob/release-8.0/go.mod
I will note that it does get correctly added back as part of the vtctld branch #195

cool, this is good to me. my expectation is this will all resolve when we finally catch up to the vtctld work in an official upstream release

This is another important callout unless we're explicitly setting a value for this everywhere.

Yup - we explicitly set this to 30s
There was a problem hiding this comment.
Well, i guess we explicitly set it for tablets; we should give our vtgate GRPC clients a heads up (or decide upon + set some explicit value) for vtgates
Backport some panic protection during ERS This takes the core of the change from vitessio#7486 and backports it into 8.0. Signed-off-by: Richard Bailey <[email protected]>
OP vitessio#7523 This basically protects from trying to catch up on replication on hosts that are likely not replicating. Signed-off-by: Richard Bailey <[email protected]>
Adds better error when there are timeouts in resource pools

This checks if a vtgate is currently filtering keyspaces before requesting the TopoServer. This is necessary because a TopoServer can't be accessed in those cases as the filtered Topo in those cases could make it unsafe to make writes since all reads would be returning a subset of the actual topo data. The only use of the requested topoServer that I found was in the DDL handling path and was introduced in vitessio#6547. This is deployed on dev but should get testing (endtoend or unit, unclear on best path atm) before going upstream.

Incompatible Changes
The following PRs made changes to behavior that clients might be relying on. They should be reviewed carefully so that client code can be changed in concert with a Vitess release deployment.
The three errors being changed:
A Note about VTctld builds
This does not include everything for our bleeding edge deployments of vtctld to support the feature work we're doing that. That will be rolled out is a different branch that will initially be designed to merge into these changes and going forward (hopefully) easily cherry pick into 9.0 etc.

How this branch was constructed
First I determined where release-7.0 diverged from upstream's mainline:
Then I sanity checked it felt reasonable
And cut a branch for the release starting there (since new additions for 8.0 effectively begin from that point)
This is a bit of hand waving this a little because I forgot I wanted to land on this branch so I had to juggle branch names after the fact... but in practice
Now actually construct the PR; base it on
upstream/release-8.0And fold in our custom patches
Note that I did not cherry-pick Guido's change since it has been merged upstream
