The generator's import reads its comma-separated table list with
c.Request.FormValue("tables"), which on a request declaring itself as JSON reads
the URL query and nothing else. go-admin-ui v3.2.0 began sending that list in
the body, so the handler saw an empty string, asked information_schema for a
table named "", and every import failed with "table name cannot be empty！" —
on a fresh installation that is the first thing the generator is asked to do.
tablesToImport reads the query first and falls back to the body, so a front end
sending either works against this server. It also drops blank entries:
splitting "" yields one empty name rather than nothing at all, which is why the
old code reached a database query at all before failing.
The front end sends the list in the query again on its side; this half is what
lets an installation already running v3.2.0 recover without changing it.
The string was spelled out at each site that raises it, and once more in the
test file that asserts on it. A test holding its own copy cannot tell the
difference between the handler answering something else and the message having
been reworded: it goes on asserting a string the server no longer sends, and
goes on passing.
The three copies in app/other/models/tools are left alone; they are raised from
a different layer and nothing asserts on them.
newEngine takes the method, path and handler, so a second test file does not
have to restate the sqlite connection, the driver override and its cleanup, the
CustomError middleware and the two context keys. serveJSON does the same for
running one request and decoding the envelope.
Nothing about what is asserted changes; newColumnListEngine and columnListMsg
keep their names and their callers.
Every import of the module changes, not only the seven packages that
moved out of sdk/pkg: Go requires the major version in the path from v2
on. Both happen in one pass —
go run github.com/go-admin-team/go-admin-core/tools/coreupgrade@v2.0.0 -w -v2 .
go mod tidy
— which is the command the release notes give, run here as a consumer
would run it. 210 imports across 95 files.
The compatibility shims this used are gone in v2, so the paths that
moved had to move: sdk/pkg/captcha, sdk/pkg/jwtauth and its user
package, sdk/pkg/response and sdk/pkg/casbin.
The count of unformatted files is unchanged at 34, none of them touched
by this: the tool reformats a file only if it was already gofmt clean,
so a migration cannot disappear into whitespace.
pkg.Assert panics when its condition is false, so
Assert(TableName == "", "table name cannot be empty") rejected every
request that carried a table name and let the empty one through. The
model layer repeated the inversion with if TableName != "" { return
error }, so either one alone was enough to break the endpoint.
Flip both, and hoist the model guard out of the mysql branch so it
matches GetList ten lines below, which had it right all along.
