问题 A related question here shows how to do this with just clog: How to redefine clog to tee to original clog and a log file? The question now is how to also do this for cerr at the same time. With the above question, output to cerr does not end up in the log file where it is also needed. The goal is that whatever goes to either clog or cerr ends up in the log file once, so both clog and cerr need to be teed to a shared log file. 回答1: this code will redirect both std::cout and std::cerr to an

问题 As the title says, I've set the max length for the php error log, but it seems to keep growing much much larger than 1024. I am using the correct php.ini, I've restarted apache, etc. The permissions on the php log are 666. 回答1: As is typical for PHP, it is not really obvious from the name of the configuration setting, or even the documentation, but this directive applies to the length of a single log message , not the length of the log file as a whole. Use logrotate or a similar tool for what

问题 I need to merge two XML log files. One log file contains a trace with position updates. The other log file contains the received messages. There can be multiple received messages without having a position update inbetween. Both logs have timestamps: The trace log uses <date> (eg. 14.7.2012 11:08:07) The message log uses a unix timestamp <timeStamp> (eg. 1342264087) The structure of the trace looks like: <item> <date>14.7.2012 11:08:07.222</date> <MyPosition> // Position data </MyPosition> <

问题 Seems pretty straight forward. Documentation at http://velocity.apache.org/engine/devel/developer-guide.html#Configuring_Logging says to set the runtime.log property. Here's what I got for all my properties. velocityEngine.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templatesPath); velocityEngine.setProperty("runtime.log", "/path/to/my/file/velocity.log"); velocityEngine.setProperty("resource.loader", "string"); velocityEngine.setProperty("string.resource.loader.class", "org

问题 Currently I am redirecting a script to a log file with the following command: python /usr/home/scripts/myscript.py 2>&1 | tee /usr/home/logs/mylogfile.log This seems to work but it does not write to the file as soon as there is a print command. Rather it waits until there is a group of lines that it can print. I want the console and the log file to be written to simultaneously. How can this be done with output redirection. Note that running the script on the console prints everything when it

问题 This is really a two prong question. One, I'm experiencing a phenomenon where SQL server consumes a lot of tempDB log file space when using a global temp table while using a local temp table will consume data file space? Is this normal? I can't find anywhere on the web where it talks about consuming log file space in such a way when using global temp tables vs. local temp tables. Two, if this is expected behavior, is there any way to tell it not to do this :). I have plenty of data space (6

问题 Sometimes we see the device restarts automatically, while few other times I had found it switching off after long time, even battery was not low. So if we want to trace back of what actually has caused this, does we have any log file in device memory which has the cause of shutdown or restart ? Like we get the dump for the other O.S. for any errors occured causing it to restart/shutdown in specific error log file. Similarly does android has such ? It may be anywhere , even in internal memory,

问题 I'm trying to re-create this conquerclub (Risk-like) game: http://conquerclub.barrycarter.info/ONEOFF/7460216.html In other words, I want to know who owned each territory at each point in time, and how many troops they had on that territory. My primary source of information is the Game Log. Notes: % It's not in the Game Log, but all territories start w/ 3 troops. % Since we know the territory owners at the end of the game, and the Game Log mentions all owner changes, determining territory

问题 MySQL saves all changes to the database in a binary file called binary log. MySQL provides a decoder called mysqlbinlog to decode these files. I thought if I wanted to parse this log file directly from an application then I need to find a way to decode it myself using C# for instance. I know if I had the privilege I could use SHOW BINLOG EVENTS. However, parsing the file would be a better solution for me. Has any of you done that before? Any suggestions? 回答1: A look into the mysqlbinlog-tool
