MOODLE_404_STABLE
Since upgrading to 4.4, downloading the admin logs via the "Download table data as..." feature yields only a partial download of the data and appends HTML/javascript for a new page at the bottom.
We generate 200,000 - 400,000 logs on a typical day and use the logstore_standard logreader. When I ask for a download of the data for yesterday in either CSV or JSON format, the report appears to complete normally and I save the file. When I open the file, I find the first 20-30,000 rows (the ones closest to midnight) and then:
<!DOCTYPE html>
<html dir="ltr" lang="en" xml:lang="en">
<head>
<title>Error</title>
...
followed by what looks like most of the site admin search box (in HTML).
When I ask for EXCEL data, it runs for several minutes and returns the error page "This site can't be reached". With PDF, I just get a 504 gateway timeout.
Note: I can use the web interface to navigate through yesterday's 3512 pages of data without issue.
Steps to reproduce:
1. With 100,000 rows in today's (or yesterday's) log, view the first page of the logs
2. Select CSV in the "Download table data as" pull-down.
3. Click "Download"
4. Open the resulting file in your favorite editor
I expected:
A CSV file with the 100,000 rows
I received:
A CSV file with 23,670 rows of data followed by the HTML and javascript of a moodle web page.
