问题 Fatal error : Allowed memory size of 134217728 bytes exhausted (tried to allocate 523800 bytes) in /Library/WebServer/Documents/XMLDataStore.class.php on line 981 The curious thing about this error is not the memory leak, which would be easy enough to troubleshoot. Rather, it is the fact that XMLDataStore.class.php is only 850 lines long, which I have verified in multiple text editors. This is with the PHP 5.3 bundled with Snow Leopard. I'm not using an opcode cache. Here is my php.ini: allow

问题 First I want to explain what am I doing and then my problem. I need to scan a css file and obtain all its internal links(images mainly), but I need to get the line number where the links were found. Right now I am parsing the files using flute library and it works very well also I am using LineNumberReader in order to obtain the line number where a link was found, but this class throws an incorrect line number. For example: the link ../../image/bg.gif is in the line number 350 but the method

问题 I have wrapped the console API to provide granular logging levels as well as few other sugar features. This works fine, the only problem is that firebug (or whatever other console) will always report the line number the log came from as the line the console API itself is invoked. How would you suggest I make the console log the line number at which I call my wrapper function? I would prefer a cross browser solution but failing that a firebug plugin could be a good start. fyi I call my loging

问题 I would like to print out my debug message with line number in VB.net application. I did like this, Dim st As StackTrace Dim sf As StackFramee st = New StackTrace(New StackFrame(True)) sf = st.GetFrame(0) Console.WriteLine.("Line " & sf.GetFileLineNumber()） I wanna put the snippet to a class, everytime I call logMsg method to log my message with line number in source code. But I found if I put the snippet above into a class, the line number was always same, that's the line which I new 'st'.

问题 How can I implement a method to return the line-number of the line currently being scanned from a file. I have two scanners, one for the file (fileScanner) and another for the line (lineScanner) this is what I have, but I don't know if I need the linenumber in the constructor! public TextFileScanner(String fileName) throws FileNotFoundException { this.fileScanner = new Scanner(new File(fileName)); this.lineScanner = new Scanner(this.fileScanner.nextLine()); this.lineNumber = 1; } and I need

问题 I have a line number of a Java source file and want to get the sourounding method for that line number programatically. I looked into ANTLR which didn't help me much. Janino (http://www.janino.net) seems promising, I would scan and parse (and if necessary compile) the code. Then I could use JDI and ReferenceType.locationsOfLine(int lineNumber) Still I don't know how to use JDI for doing this and didn't find a tutorial that goes anywhere in this direction. Maybe there is some other way that I

问题 When I do a git diff or a git log -p , how do I get line numbers of the source file(s) inlined with the output? I tried to look it up man git-diff | grep "line numbers" and I tried googling but got nothing quickly. 回答1: You can't get human-readable line numbers with git diff There aren't currently any options to get line-numbers displayed vertically on the side with git diff . Unified-diff format That information is available in the (c)hunk headers for each change in the diff though, it's

问题 I can :set number from within a file I'm editing but how can I have them always be on by default? 回答1: Add set number to your .vimrc file in your home directory. If the .vimrc file is not in your home directory create one with vim .vimrc and add the commands you want at open.
