Currently there is an issue in v39 (introduced in this PR) which needs to be fixed before merging

lafriks · 2017-09-27T12:06:49Z

@daviian what issue?

daviian · 2017-09-27T12:16:41Z

@lafriks https://github.com/daviian/gitea/blob/c9430b29a5220e2297aa9b93b70a25062f831509/models/migrations/v39.go#L73
Xorm doesn't return anything here, despite there should be 96 units in my testdata with UnitTypeIssue

Good catch. Nearly impossible to see

strk · 2017-10-04T07:47:05Z

Any chance to see an automated test for migration from a dump of a Gogs0.99 database ?

lafriks · 2017-10-04T09:21:26Z

@strk not in the scope of this PR but otherwise I agree we would need that but I currently have no idea how to achieve that

strk · 2017-10-04T10:24:04Z

Trusted/untested LGTM - please make sure to manually test it !

lafriks · 2017-10-04T10:25:21Z

@strk me and @daviian have tested it multiple times

mrexodia · 2017-10-06T20:55:05Z

Just tried this on a database with version=17 and it appears to have worked! (raspberry pi zero w, had to change swap size to 1024mb to compile)

# Make errors about go-bindata go away
go get github.com/jteeuwen/go-bindata
cd $GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata
go build
export PATH=$PATH:$GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata

# Get gitea
go get -d -u code.gitea.io/gitea
cd $GOPATH/src/code.gitea.io/gitea

# Get PR 2604 that fixes migration issues
git fetch origin pull/2604/head:pr-2604
git checkout pr-2604

# Build gitea (will take some time)
TAGS="bindata sqlite" make generate build

I kind of followed https://docs.gitea.io/en-us/install-from-source/ and https://docs.gitea.io/en-us/upgrade-from-gogs/ and @lafriks told me to change the gogs.db with the following SQL command: update version set version=14; which may or may not have contributed to this being successful...

daviian · 2017-10-06T21:17:09Z

@mrexodia Glad to here that 😃 Setting the version to 14 is necessary as otherwise required migrations (in your example 14 to 17) are not applied to the database.

Morlinest · 2017-10-07T15:13:52Z

LGTM, code looks good, trusting manual tests of @lafriks & @daviian

lafriks · 2017-10-07T15:25:36Z

Make LG-TM work again

daviian · 2017-10-08T12:04:04Z

@lunny @lafriks Should I create a backport to 1.2?

lafriks · 2017-10-08T12:19:31Z

@daviian sure, go ahead
