bug#33862: "guix gc" failing to complete

[Ethan O'Quin]

[-- Attachment #1: Type: text/plain, Size: 407 bytes --]

Every time I run "guix gc" the process fails with:

"guix gc: error: build failed: executing SQLite statement: FOREIGN KEY constraint failed"

This occurs every time "guix gc" is run, although it progresses for a moment before it fails.

The issue was encountered on guix 0.16.0-7.6f1e0bb on GuixSD as of December 24, although I have encountered it repeatedly back to some time in October, possibly earlier.

Try

# guix gc --verify

If that doesn't work, then

$ cp /var/guix/db/db.sqlite /tmp/
$ sqlite3 /tmp/db.sqlite
sqlite> .tables
sqlite> .schema Refs

Do you see a foreign key here with "on delete restrict", Refs.reference ?

sqlite> .schema DerivationOutputs

No "on delete restrict" here?

sqlite> .schema FailedPaths

No "on delete restrict" here?

sqlite> .schema ValidPaths

No "on delete restrict" here?

Also, is there a hash value somewhere in the error messages?

I'm also getting this problem.

`guix gc --verify` doesn't fix it for me.

Here is the output for each of the commands you (Danny Milosavljevic) suggested:

$ cp /var/guix/db/db.sqlite /tmp/
$ sqlite3 /tmp/db.sqlite
sqlite> .tables
DerivationOutputs  FailedPaths        Refs               ValidPaths       

sqlite> .schema Refs
CREATE TABLE Refs (
    referrer  integer not null,
    reference integer not null,
    primary key (referrer, reference),
    foreign key (referrer) references ValidPaths(id) on delete cascade,
    foreign key (reference) references ValidPaths(id) on delete restrict
);
CREATE INDEX IndexReferrer on Refs(referrer);
CREATE INDEX IndexReference on Refs(reference);

sqlite> .schema DerivationOutputs
CREATE TABLE DerivationOutputs (
    drv  integer not null,
    id   text not null, -- symbolic output id, usually "out"
    path text not null,
    primary key (drv, id),
    foreign key (drv) references ValidPaths(id) on delete cascade
);
CREATE INDEX IndexDerivationOutputs on DerivationOutputs(path);

sqlite> .schema FailedPaths
CREATE TABLE FailedPaths (
    path text primary key not null,
    time integer not null
);

sqlite> .schema ValidPaths
CREATE TABLE ValidPaths (
    id               integer primary key autoincrement not null,
    path             text unique not null,
    hash             text not null,
    registrationTime integer not null,
    deriver          text,
    narSize          integer
);
CREATE TRIGGER DeleteSelfRefs before delete on ValidPaths
  begin
    delete from Refs where referrer = old.id and reference = old.id;
  end;

Does the solution

        Try

        # guix gc --verify

        If that doesn't work, then… 

work for you?  If not, please report what is wrong?

Since it is 2years old, I hope you fixed the issue in the meantime.


All the best,
simon

No news after 2 years and waiting more than 4 weeks for moreinfo, I am
closing now.

If I am missing something, feel free to reopen.
