Same error happens on R14.

change rebar config to depend on mochiweb branch/main is optional
{deps, [
{mochiweb, ".*", {git, "https://github.com/mochi/mochiweb.git", {branch, "main"}}}
]
}.

Haven't you met such a problem?

Is it possible to include a working example for syslog appender, with sample conf for syslog as well? it is not simple to set up such that it shows up in the system,. that will at least give developer who is not sysadmin some pointers.
thanks

Hi,
We have following section in config:

logger benchmark_logger{
file_appender benchmark_appender{
dir = "log/",
level = info,
file = benchmark,
type = size,
max = 10000,
%max = 5,
suffix = log,
rotation = 9999999,
format = '[%d %T] %l%n'
}
During writting to this log we have only one file in log/ directory also log4erl:info/2 is hanging very long time.

file_appender.erl

rotate(#file_appender{fd = Fd, dir=Dir,  file_name=Fn, counter=Cntr, rotation=Rot, suffix=Suf, log_type=Ltype, level=Level, format=Format} = _S) ->
    file:close(Fd),
    ?LOG("Starting rotation~n"),
    rotate_file(Dir ++ "/" ++ Fn, Rot - 1, Suf),
    Src = Dir ++ "/" ++ Fn ++ "." ++ Suf,
    {ok ,Fd2} = file:open(Src, ?FILE_OPTIONS_ROTATE),
    State2 = #file_appender{dir = Dir, file_name = Fn, fd = Fd2, counter=Cntr, log_type = Ltype, rotation = Rot, suffix=Suf, level=Level, format=Format},
    {ok, State2}.

rotate_file(FileBase, Index, Suffix) when Index > 0 ->
    file:rename(FileBase ++ "_" ++ integer_to_list(Index) ++ "." ++ Suffix, 
        FileBase ++ "_" ++ integer_to_list(Index + 1) ++ "." ++ Suffix),
    rotate_file(FileBase, Index - 1, Suffix);
rotate_file(FileBase, _Index, Suffix) ->
    file:rename(FileBase ++ "." ++ Suffix, FileBase ++ "_1." ++ Suffix).

As you can see in rotate_file/3 function we try check file via file:rename many times (9999999), even if file not existed.

Hi there,

I relaized that user deifnied log levels are not written. Is it known issue ?
I'm usng latest version (0.8.6) and trying to print custom loglevel like "dump" but it doesn't print unless I have set level set as "debug".

Thanks

I have added files, required to make debian package.
Aren't you interested in it?

BTW, maybe you merge with http://github.com/kenpratt/log4erl fork and I will rebase my repo?

how to solve it , why need mochiweb ??

https://github.com/ahmednawras/log4erl/blob/master/src/file_appender.erl#L155

1. in log_manager.erl function notify_logger use gen_event:sync_notify(...) it was blocked util message ahead was handled,why not use method gen_event:notify(...)

2. when so many messages send to defalut_logger ,the memory was cost a lot,why not use another form of message queue,like ets cache?
