This must be done explicitely though, as in the case of 'limit' being undefined, the default as before, 50 will be used. Signed-off-by: Daniel Tschlatscher --- Changes from v3: * NEW patch This patch also affects the API endpoints for: * the ceph log file * replication log files * firewall Guest and Host log files It does not change how they behave in the GUI though, as all of the corresponding API calls there do not specify a 'limit=0' parameter. In fact, none of them specify any limit, therefore, the default value of 50 still applies. src/PVE/Tools.pm | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) diff --git a/src/PVE/Tools.pm b/src/PVE/Tools.pm index eb81b96..6072eb7 100644 --- a/src/PVE/Tools.pm +++ b/src/PVE/Tools.pm @@ -1278,9 +1278,10 @@ sub dump_logfile { return ($count, $lines); } - $start = 0 if !$start; - $limit = 50 if !$limit; + $start = $start // 0; + $limit = $limit // 50; + my $read_until_end = ($limit == 0) ? 1 : 0; my $line; if ($filter) { @@ -1288,18 +1289,22 @@ sub dump_logfile { while (defined($line = <$fh>)) { next if $line !~ m/$filter/; next if $count++ < $start; - next if $limit <= 0; + if (!$read_until_end) { + next if $limit <= 0; + $limit--; + } chomp $line; push @$lines, { n => $count, t => $line}; - $limit--; } } else { while (defined($line = <$fh>)) { next if $count++ < $start; - next if $limit <= 0; + if (!$read_until_end) { + next if $limit <= 0; + $limit--; + } chomp $line; push @$lines, { n => $count, t => $line}; - $limit--; } } -- 2.30.2
