[4.1 Alpha 1] New installation stuck in a loop at Step 7

I've tried installing a new instance of VaultWiki 4.1 Alpha 1 to my XF2.0 local dev environment, however the addon installation is hanging at step 7, or rather it seems to be caught in a loop.

Here is an excerpt of the install log around the point where the loop starts:

Code:

== Step 4 ==
creating_attachment_directory

== Step 5 ==
Adding data to table: xf_option
Creating prefix for Special pages

== Step 6 ==
Adding data to table: vw_permission

== Step 7 ==
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special... ((3))

== Step 7 ==
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special... ((3))

== Step 7 ==
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special... ((3))

After seeing 43 instances of Step 7, I killed the addon installation. No errors were logged by XenForo. The installer was reporting 477 queries at this point.

This was encoutered with XenForo 2.0.7, and I wasn't using the CLI options for installing VaultWiki ... just the standard web-based one through the admin cp.

I've since upgraded my local dev forum to 2.0.12 and tried to resume the installation (XF says Action pending, Last action: install:7). It still seems to be stuck in a loop, with 53 instances of step 7 now.

Please check your database for existence of a table called vw_upgradelog and provide the contents of this table.
If the table does not exist, it would explain this.

If the table exists but does not contain a row like

Code:

C 0.0.0 6 3

if it has a 0 in the last column or the row is missing, there might be a database error being suppressed. In that case, let's try to get more information about the error. In src/addons/vw/vw/Setup/Caller/Install.php, find:

Code:

\vw_DB::get()->func()->hide_errors();

Replace with:

Code:

//\vw_DB::get()->func()->hide_errors();

vw_upgradelog contains two records.

upgradetype version step offset
C 0.0.0 6 3
F 4.1.0 Alpha 1 0 0

So we know that it is at least writing the correct position. Let's see if it's reading the position on the next go. In src/addons/vw/vw/Setup/View.php, find:

Code:

$text = $this->sprintf($text, $step);

AFTER it, add:

Code:

//if ($this->caller->offset) { $text .= ' (' . $this->caller->offset . ')'; }

This will add the starting offset next to the step number in the log, whereas the next (number) would be the ending offset. I suspect the starting offset is becoming 0 somewhere.

Once you make this change, allow the installer to perform 2 or 3 cycles before aborting again. Then check the bottom of the log file for new information. Please include about 5 of the steps listed, starting from the bottom.

I've let the installer run for a bit and there are now a total of 75 step 7 instances.

What ends up being logged is step 7 with a zeroed offset each time. For completeness here are the last three steps from the log:

Code:

== Step 7 (0) ==
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special... ((3))

== Step 7 (0) ==
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special... ((3))

== Step 7 (0) ==
Preparing database
Adding data to table: vw_index
Adding data to table: vw_permission
Adding data to table: vw_special... ((3))

Okay, let's find the 0. This can go much faster if you submit a ticket, but if you prefer to do it this way (to see how everything works together), I can keep posting edits for you.

In src/addons/vw/vw/Setup.php, find:

Code:

$version = $caller->get('versioninfo');

AFTER it, add:

Code:

\XF::dump($install_key); \XF::dump($version);

Find:

Code:

$result = $this->vwRunStep('install', $stepObject, $stepParams, $internalStep);

BEFORE it, add:

Code:

\XF::dump($stepParams);

Once the output is displayed on screen, cancel the browser refresh so you have a chance to copy it.

I'm using a local development environment for the VW 4.1 alphas so without external FTP access it might be 'interesting'

Code:

"C"

array:3 [
  "C" => "0.0.0"
  "steps" => array:2 [
    "C" => array:2 [
      0 => 6
      1 => 3
    ]
    "F" => array:2 [
      0 => 0
      1 => 0
    ]
  ]
  "F" => "4.1.0 Alpha 1"
]

I believe I've found it. In src/addons/vw/vw/Setup/Caller/AbstractCaller.php, find:

Code:

$this->params["$name"] = $value;

Replace with:

Code:

$this->params["$paramname"] = $value;

We have lift off! Setup has now made it through to the importing add-on data stage (after a pause at step 9 for user input).
