Tests: limit_req tests for 0.8.18 changes and bug.
1. Make sure rejected requests are not counted, as leaky bucket algorithm
suggests (finally correctly done in 0.8.18).
2. Make sure negative excess values are handled properly (bug appeared in
0.8.18, fixed in 0.8.19).

#!/usr/bin/perl # (C) Maxim Dounin # Test for http backend not closing connection properly after sending full # reply. This is in fact backend bug, but it seems common, and anyway # correct handling is required to support persistent connections. # There are actually 2 nginx problems here: # # 1. It doesn't send reply in-time even if got Content-Length and all the data. # # 2. If upstream times out some data may be left in input buffer and won't be # sent to downstream. ############################################################################### use warnings; use strict; use Test::More tests => 4; use IO::Select; BEGIN { use FindBin; chdir($FindBin::Bin); } use lib 'lib'; use Test::Nginx; ############################################################################### select STDERR; $| = 1; select STDOUT; $| = 1; my $t = Test::Nginx->new(); $t->write_file_expand('nginx.conf', <<'EOF'); master_process off; daemon off; events { } http { access_log off; root %%TESTDIR%%; client_body_temp_path %%TESTDIR%%/client_body_temp; fastcgi_temp_path %%TESTDIR%%/fastcgi_temp; proxy_temp_path %%TESTDIR%%/proxy_temp; server { listen 127.0.0.1:8080; server_name localhost; location / { proxy_pass http://127.0.0.1:8081; proxy_read_timeout 1s; } location /uselen { proxy_pass http://127.0.0.1:8081; # test will wait only 2s for reply, we it will fail if # Content-Length not used as a hint proxy_read_timeout 10s; } } } EOF $t->run_daemon(\&http_noclose_daemon); $t->run(); ############################################################################### TODO: { local $TODO = 'not fixed yet, patches under review'; local $SIG{__WARN__} = sub {}; like(http_get('/'), qr/SEE-THIS/, 'request to bad backend'); like(http_get('/multi'), qr/AND-THIS/, 'bad backend - multiple packets'); like(http_get('/nolen'), qr/SEE-THIS/, 'bad backend - no content length'); like(http_get('/uselen'), qr/SEE-THIS/, 'content-length actually used'); } ############################################################################### sub http_noclose_daemon { my $server = IO::Socket::INET->new( Proto => 'tcp', LocalAddr => '127.0.0.1:8081', Listen => 5, Reuse => 1 ) or die "Can't create listening socket: $!\n"; while (my $client = $server->accept()) { $client->autoflush(1); my $multi = 0; my $nolen = 0; while (<$client>) { $multi = 1 if /multi/; $nolen = 1 if /nolen/; last if (/^\x0d?\x0a?$/); } if ($nolen) { print $client <<'EOF'; HTTP/1.1 200 OK Connection: close TEST-OK-IF-YOU-SEE-THIS EOF } elsif ($multi) { print $client <<"EOF"; HTTP/1.1 200 OK Content-Length: 32 Connection: close TEST-OK-IF-YOU-SEE-THIS EOF select undef, undef, undef, 0.1; print $client 'AND-THIS'; } else { print $client <<"EOF"; HTTP/1.1 200 OK Content-Length: 24 Connection: close TEST-OK-IF-YOU-SEE-THIS EOF } my $select = IO::Select->new($client); $select->can_read(10); close $client; } } ###############################################################################
