Erlang: how to disable “crash dump” & “core dump” generation?

由 北城以北 提交于 2019-12-06 04:14:37
问题 Is there any way to disable the generation of "crash dump" & "core dump" files when running 'erl' ? PS: I know about the "+d" option of erl but I want to completely disable the generation of crash/core dumps. 回答1: If you are into dirty patching, you can insert a return statement right at the top of the erl_crash_dump_v function in break.c, and recompile. 回答2: You may also set the ERL_CRASH_DUMP environment variable to "/dev/null". It designates to which file the crash dump should be written.

问题 erlang is a strange language to me, this week i've been playing with multiple languages and I've come here for help often, now I'm on erlang and I'm stuck once again :) Basically All i'm trying to do is the following but in erlang: Dim objFSO, objFile, objFolder Set objFSO = Server.CreateObject("Scripting.FileSystemObject") Set objFolder = objFSO.GetFolder(currentDirectory)) For Each objFile in objFolder.Files do something with the file do something else do more stuff Next The closest i've

Erlang: is there an API to 'epmd'?

由 一笑奈何 提交于 2019-12-06 03:49:34
问题 Is there a way to query the name table that epmd daemon manages? The nodes() function isn't very helpful on that front. NOTE: I am looking for an API aside from parsing the output generated through stdout. 回答1: To query nodes visible for epmd, call: EpmdModule = net_kernel:epmd_module(). % erl_epmd by default EpmdModule:names(). To get a list of connected nodes and their ports: erlang:system_info(dist). erlang:system_info(dist_ctrl). The first call returns you the table in a crash dump format

Erlang and binary with cyrillic

由 我是研究僧i 提交于 2019-12-06 03:29:22
问题 I need to be able to use binaries with Cyrillic characters in them. I tried just writing <<"абвгд">> but I got a badarg error. How can I work with Cyrillic (or unicode) strings in Erlang? 回答1: If you want to input the above expression in erlang shell , please read unicode module user manual. Function character_to_binary , and character_to_list are both reversable function. The following are an example: (emacs@yus-iMac.local)37> io:getopts(). [{expand_fun,#Fun<group.0.33302583>}, {echo,true},

问题 I have a couple of functions that perform HTTP POST/GET/HEAD requests. For the POST request I use this: http:request(post, {Url, [], ContentType, Body}, [], []). While for the HEAD/GET I use: http:request(Method, {Url, []}, [], []) How can I write this two calls in a unique one? POST request has those two additional variables with respect to GET/HEAD request. I tried with empty lists but I got: ** exception error: no function clause matching Thank you very much 回答1: To use the call to httpc

What other systems beside Erlang are based on “Green Processes”?
