From 306a0f84cebfb0c5262f439c95aa5006829ac135 Mon Sep 17 00:00:00 2001 From: David Cook Date: Thu, 29 Oct 2020 04:24:31 +0000 Subject: [PATCH] Bug 26854: Close STDERR when forking stage-marc-import.pl We need to close STDERR when forking stage-marc-import.pl, or else the CGI session with Apache httpd does not properly finish. This leads to unexpected behaviour across different httpd versions, operating systems, etc. This patch closes the STDERR file handle when forking a child process to do MARC imports, and it re-opens STDERR to a log file in the logdir directory to catch any import errors. Test plan: 1. Apply the patch 2. Go to http://localhost:8081/cgi-bin/koha/tools/stage-marc-import.pl 3. Upload a MARC file with a large number of records (e.g. 30,000 records) 4. Open F12 dev tools 5. Click on "Network" tab 6. Clear all existing network logs 7. Click "Stage for import" 8. After ~30 seconds, the request to stage-marc-import.pl should return a 200 code 9. Immediately, calls to background-job-progress.pl should start, and the "Job progress" bar should update at a maximum rate of every .5 seconds (or more realistically 1-2 seconds) --- tools/stage-marc-import.pl | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/tools/stage-marc-import.pl b/tools/stage-marc-import.pl index 0ea436351f..a5094b4616 100755 --- a/tools/stage-marc-import.pl +++ b/tools/stage-marc-import.pl @@ -122,10 +122,15 @@ if ($completedJobID) { exit 0; } elsif (defined $pid) { # child - # close STDOUT to signal to Apache that - # we're now running in the background + # close STDOUT/STDERR to signal to end CGI session with Apache + # Otherwise, the AJAX request to this script won't return properly close STDOUT; - # close STDERR; # there is no good reason to close STDERR + close STDERR; + my $logdir = C4::Context->config('logdir'); + if ($logdir && -d $logdir){ + my $logfile = sprintf("%s/%s",$logdir,'background-jobs.log'); + open(STDERR, '>>', $logfile); + } } else { # fork failed, so exit immediately warn "fork failed while attempting to run tools/stage-marc-import.pl as a background job: $!"; -- 2.11.0
