  • Get current Apache version string for display

    - by Stijn Sanders
    I'm writing an Apache module and want to get a string with the Apache name version and other details. Much like what gets added to outgoing headers, e.g.: Server: Apache/2.2.13 (Win32) I've tried code like this: apr_table_get(request_rec->headers_out,"Server") But that doesn't seem to work. Is there an API call I haven't found or am I doomed to get version resource data from httpd.exe?

  • sys.path() and PYTHONPATH issues

    - by Justin
    I've been learning Python, I'm working in 2.7.3, and I'm trying to understand import statements. The documentation says that when you attempt to import a module, the interpreter will first search for one of the built-in modules. What is meant by a built-in module? Then, the documentation says that the interpreter searches in the directories listed by sys.path, and that sys.path is initialized from these sources: the directory containing the input script (or the current directory). PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH). the installation-dependent default. Here is a sample output of a sys.path command from my computer using python in command-line mode: (I deleted a few so that it wouldn't be huge) ['', '/usr/lib/python2.7', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol'] Now, I'm assuming that the '' path refers to the directory containing the 'script', and so I figured the rest of them would be coming from my PYTHONPATH environmental variable. However, when I go to the terminal and type env, PYTHONPATH doesn't exist as an environmental variable. I also tried import os then os.environ, but I get the same output. Do I really not have a PYTHONPATH environmental variable? I don't believe I ever specifically defined a PYTHONPATH environmental variable, but I assumed that when I installed new packages they automatically altered that environment variable. If I don't have a PYTHONPATH, how is my sys.path getting populated? If I download new packages, how does Python know where to look for them if I don't have this PYTHONPATH variable? How do environment variables work? From what I understand, environment variables are specific to the process for which they are set, however, if I open multiple terminal windows and run env, they all display a number of identical variables, for example, PATH. I know there file locations for persistent environment variables, for example /etc/environment, which contains my PATH variable. Is it possible to tell where a persistent environment variable is stored? What is the recommended location for storing new persistent environment variables? How do environment variables actually work with say, the Python interpreter? The Python interpreter looks for PYTHONPATH, but how does it work at the nitty-gritty level?

  • Any way in C++ to forward declare a function prototype?

    - by jsyjr
    I make regular use of forward class declarations and pointers to such classes. I now have a need to pass a function pointer through a number of layers. I would prefer to include the header that declares my function pointer's prototype only into the module that dereferences a function pointer rather than into each layer that simply passes along that pointer value. Is this possible?

  • Is a string formatter that pulls variables from its calling scope bad practice?

    - by Eric
    I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

  • Unable to use getInt() but able to use getString() for a sqlite database

    - by mwrazam
    I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more

  • C underscore prototype syntax

    I was trying to compile a ruby module, and my compiler choked. I think it might have something to do with a line in ruby.h: void rb_check_type _((VALUE,int)); I've never seen this _ syntax before. What does it mean? Could it cause problems for my compiler (Visual Studio)?

  • How can I enable a debugging mode via a command-line switch for my Perl program?

    - by Michael Mao
    I am learning Perl in a "head-first" manner. I am absolutely a newbie in this language: I am trying to have a debug_mode switch from CLI which can be used to control how my script works, by switching certain subroutines "on and off". And below is what I've got so far: #!/usr/bin/perl -s -w # purpose : make subroutine execution optional, # which is depending on a CLI switch flag use strict; use warnings; use constant DEBUG_VERBOSE => "v"; use constant DEBUG_SUPPRESS_ERROR_MSGS => "s"; use constant DEBUG_IGNORE_VALIDATION => "i"; use constant DEBUG_SETPPING_COMPUTATION => "c"; our ($debug_mode); mainMethod(); sub mainMethod # () { if(!$debug_mode) { print "debug_mode is OFF\n"; } elsif($debug_mode) { print "debug_mode is ON\n"; } else { print "OMG!\n"; exit -1; } checkArgv(); printErrorMsg("Error_Code_123", "Parsing Error at..."); verbose(); } sub checkArgv #() { print ("Number of ARGV : ".(1 + $#ARGV)."\n"); } sub printErrorMsg # ($error_code, $error_msg, ..) { if(defined($debug_mode) && !($debug_mode =~ DEBUG_SUPPRESS_ERROR_MSGS)) { print "You can only see me if -debug_mode is NOT set". " to DEBUG_SUPPRESS_ERROR_MSGS\n"; die("terminated prematurely...\n") and exit -1; } } sub verbose # () { if(defined($debug_mode) && ($debug_mode =~ DEBUG_VERBOSE)) { print "Blah blah blah...\n"; } } So far as I can tell, at least it works...: the -debug_mode switch doesn't interfere with normal ARGV the following commandlines work: ./optional.pl ./optional.pl -debug_mode ./optional.pl -debug_mode=v ./optional.pl -debug_mode=s However, I am puzzled when multiple debug_modes are "mixed", such as: ./optional.pl -debug_mode=sv ./optional.pl -debug_mode=vs I don't understand why the above lines of code "magically works". I see both of the "DEBUG_VERBOS" and "DEBUG_SUPPRESS_ERROR_MSGS" apply to the script, which is fine in this case. However, if there are some "conflicting" debug modes, I am not sure how to set the "precedence of debug_modes"? Also, I am not certain if my approach is good enough to Perlists and I hope I am getting my feet in the right direction. One biggest problem is that I now put if statements inside most of my subroutines for controlling their behavior under different modes. Is this okay? Is there a more elegant way? I know there must be a debug module from CPAN or elsewhere, but I want a real minimal solution that doesn't depend on any other module than the "default". And I cannot have any control on the environment where this script will be executed...
