ISLE Workflow Test

· ☕ 9 min read

ISLE v1.3.0 has been running on my staging server, DGDockerX, for about 6 weeks now and it seems to be performing as-expected with one exception… when I try to import a batch of objects using IMI, the Islandora Multi-Importer, I get the following error:

The website encountered an unexpected error. Please try again later.

An examination of Recent log messages shows…

GuzzleHttp\Exception\ConnectException: cURL error 6: Could not resolve host: sheets.googleapis.com (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) in GuzzleHttp\Handler\CurlFactory::createRejection() (line 200 of /var/www/html/sites/all/modules/islandora/islandora_multi_importer/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php).

Engaging the Local Workflow

Since I’m not at all sure what’s wrong, I feel like I need to rewind my process a bit and try to reproduce the same configuration, and error, on a local instance of this ISLE stack. This post will chronicle the steps I take to do so.

Directories

I’ll begin by opening a terminal on my workstation/host, MA8660 as user mcfatem. Then I very carefully (note the use of the --recursive flags!) clone the aforementioned projects to the host’s ~/GitHub directory like so:

Host Commands
cd ~/GitHub
git clone –recursive https://github.com/Digital-Grinnell/dg-isle.git
git clone –recursive https://github.com/Digital-Grinnell/dg-islandora.git
cd dg-isle

Launch the dg.localdomain Stack

I’m modifying the .env file in the dg-isle directory so that “local” is my target environment. Having done that, I will launch the local stack using:

Host Commands
cd ~/GitHub/dg-isle
git checkout master
docker-compose up -d
docker logs -f isle-apache-dg

The startup will take a couple of minutes, and it does not “signal” when it’s done, so that’s the reason for the last command above. The -f option will keep the output spooling to your terminal so that you don’t have to keep repeating the command over and over again. You will know the startup is complete when you see something like the following at the bottom of the log output:

...

Press ctrl-c to interrupt the docker logs... command and get your terminal back.

A visit to https://dg.localdomain yields a very incomplete Bartik-themed site, and it looks like we are far from creating a local Digital.Grinnell. So, the next logical step is to backup the database from https://isle-stage.grinnell.edu, and import it here.

Backup the Site Database

Let’s begin by visiting the site’s home page and using the Quick Backup block at the bottom of the right-hand sidebar. Normally I would select a Backup Destination: Manual Backups Directory option to save the database backup on the server, but in this case it will be advantageous to have the backup in-hand, locally. So, I choose Backup Destination: Download instead, and the result is in my local ~/Downloads directory, specifically:

/Users/markmcfate/Downloads/DigitalGrinnell-2020-02-03T14-33-13.mysql.gz

Import the Database Backup Locally

This is as simple as:

White Screen of Death

Not good, when I visit https://dg.localdomain now I get a dreaded WSOD. So I peek at the Apache container logs using docker logs isle-apache-ld and find this:

[Mon Feb 03 20:41:55.684244 2020] [php7:error] [pid 13002] [client 172.20.0.4:43034] PHP Fatal error:  require_once(): Failed opening required '/var/www/html/sites/all/modules/islandora/islandora_multi_importer/vendor/autoload.php' (include_path='.:/usr/share/php') in /var/www/html/sites/all/modules/islandora/islandora_multi_importer/islandora_multi_importer.module on line 19, referer: https://dg.localdomain/admin/config/system/backup_migrate/restore?render=overlay

Bottom line, there are critical issues with IMI, the Islandora Multi-Importer, just as there were in staging. Hmm, what to do now?

Fixing IMI

I open a terminal into the Apache container and attempt to repair/re-install IMI like so:

Apache Container Commands
cd /var/www/html/sites/all/modules/islandora/islandora_multi-importer
git remote -v
git status
composer install

The commands and output from all of this are reflected in this gist.

Is It Fixed? Yes, Sort Of

A browser visit to https://dg.localdomain demonstrates that the site is back! However, the site is currently showing Operating in maintenance mode. Go online, and there are multiple warnings indicating:

User warning: The following module is missing from the file system: islandora_binary_object.

When I click the Go online link and complete the operation, the site does indeed respond by showing me an almost-proper home page, complete with numerous collection objects. I says it’s “almost-proper” because in addition to the top-level collections, the site is also showing a host of individual objects. This should NOT be the case, but I can think of a handful of remedies, including:

  • Using the Development menu Clear cache link to do just what the name says.

Ok, so that actually worked; no need to go farther.

Will the Same Fixes Work on Staging?

Only one way to find out. First, I’m going to snapshot the DGDockerX staging server. Done. Then…

Apache Container Commands
cd /var/www/html/sites/all/modules/islandora/islandora_multi-importer
composer install

And the output this time says:

So, to fix this I tried, and got back this:

Next stop… a staging copy of Digital.Grinnell on DigitalOcean? Yup, headed there now. 😦 But the address will be https://staging.summittservices.com, when it’s ready.

That’s a wrap. Until next time…
