Add postgres datastore type #5403

JamesChristie · 2018-08-27T18:32:48Z

This is work that aims to integrate changed submitted here and here. No changes have been made to the gx package hashes as the work it depends upon has not yet been accepted.

Stebalien · 2018-08-27T19:25:32Z

Thank you for the PR! Just a bit of a heads-up, we're a bit oversubscribed on quite a few fronts at the moment and the changes to sql-datastore are non-trivial so it may be a while before we get a chance to do a thorough review.

Quick things:

You can run gx release patch in the dependencies yourself to release new (non-canonical) versions yourself.
You can then update these dependencies here by running gx update $NewHash. Getting the tests to pass first will help speed up the review process significantly.

JamesChristie · 2018-08-28T13:21:19Z

I'm planning to do just that as soon as the PRs this depends on are merged! As soon as those are done, I'll update this pull; for the time being, it's here for posterity's sake.

repo/fsrepo/datastores.go

+}
+
+type postgresDatastoreConfig struct {
+	path string


path isn't needed here either.

magik6k · 2018-12-12T16:37:29Z

repo/fsrepo/datastores.go

+}
+
+func (postgresDatastoreConfig) Create(path string) (repo.Datastore, error) {
+	pg := postgresdb.Options{}


This should get Host/User/Password/Database from config.

When initializing node with this backend user could pass those using env vars. in config profile we'd just call os.Getenv.

We then could provide a simple script like the one below to avoid storing passwords in shell history

#!/bin/sh [check args] export IPFS_PG_HOST=$1 export IPFS_PG_USER=$2 export IPFS_PG_DATABASE=$3 printf "${IPFS_PG_USER}@${IPFS_PG_HOST} password:" stty -echo read IPFS_PG_PASSWORD stty echo export IPFS_PG_PASSWORD ipfs init --profile=postgres

Thanks for the feedback! Making these changes now. I think we could also use the PGPASSFILE env variable to avoid directly storing the password as an env variable.

repo/fsrepo/datastores.go

+func (c *postgresDatastoreConfig) DiskSpec() DiskSpec {
+	return map[string]interface{}{
+		"type": "postgresds",
+		"path": c.path,


path is not needed here, but I'm not sure what to put here that makes sense. My guess would be user+database, as host/password may change frequently in some setups.

Sorry for taking so long and you having to fight with gx, but this is getting there.

Some things in other places:

Some of my pervious review comments still need addressing Implement go-ipfs datastore interface for postgres (#2) go-ds-sql#2
Git history in Add postgres profile go-ipfs-config#5 got a bit messy

There are also some merge conflicts here, if you don't want to fight with them, once other review comments are addressed I can fix them for you (it will likely involve gx too)

But other than that it's looking good.

i-norden · 2019-01-08T20:50:14Z

I believe I've addressed all of the above issues. The required sql-datastore PR has been merged but the go-ipfs-config PR still needs to be merged, iptb-plugins will then need to be gx-ified with the new go-ipfs-config hash, and then finally go-ipfs can be gx-ified with the new go-ipfs-config and iptb-plugins hashes.

Jenkins seems to be unable to fetch dependencies from you - https://ci.ipfs.team/blue/organizations/jenkins/IPFS%2Fgo-ipfs/detail/PR-5403/44/pipeline. (gitcop warning needs fixing tee)

After making some very minor last minute changes to sql-datastore.. I forgot to re-gx-ify the package and so it was merged with the wrong hash :(

My apologies, sql-datastore will need a gx release patch performed.

i-norden · 2019-01-24T18:49:43Z

sql-datastore has been updated with the correct hash and make gx-deps is passing where it previous failed, but we still run into an issue with the sql-datastore dependency when running the shell script https://ci.ipfs.team/blue/organizations/jenkins/IPFS%2Fgo-ipfs/detail/PR-5403/51/pipeline.

I am also confused because the travis-ci builds are passing on OSX and only run into this issue with sql-datastore with the Linux builds.

Before this can be merged go-ipfs-config PR needs to be merged and its hash updated here and in iptb-plugins, and then the iptb-plugins hash needs to be updated here as well.

Stebalien · 2019-01-24T19:46:07Z

Lol. It looks like gx is case sensitive when it comes to language names.

Stebalien · 2019-01-24T19:49:02Z

Try again with: QmZmPKg1RKY2Cy5czKEBJTfDYzenbGww2pFNQKxLSKrPRB

(you're not the first to find this, apparently: whyrusleeping/gx#187)

i-norden · 2019-01-24T23:40:02Z

Yay that seems to have fixed the problem, thanks! It looks like the QmZmPKg1RKY2Cy5czKEBJTfDYzenbGww2pFNQKxLSKrPRB hash didn't capture the changes from ipfs/go-ds-sql#6 so we might want to gx release patch one more time although it appears the error we are getting now is just due to waiting on the updated go-ipfs-config dependencies.

That was just a bug that has been fixed in master. I've rebased for you.
