  • When would I need to call base() in C#?

    - by user310291
    My BaseClass Constructor is called whereas I have a constructor in derived class so when would I need to call base() ? class BaseClass { public BaseClass() { Debug.Print("BaseClass"); } } class InheritedClass : BaseClass { public InheritedClass() { Debug.Print("InheritedClass"); } } private void Form1_Load(object sender, EventArgs e) { InheritedClass inheritedClass = new InheritedClass(); } Output 'Inheritance.vshost.exe' (Managed (v4.0.30319)): Loaded 'C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Accessibility\v4.0_4.0.0.0__b03f5f7f11d50a3a\Accessibility.dll' 'Inheritance.vshost.exe' (Managed (v4.0.30319)): Loaded 'C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Configuration\v4.0_4.0.0.0__b03f5f7f11d50a3a\System.Configuration.dll', Skipped loading symbols.

  • Concatenation awk outputs

    - by Rookie_22
    I'm using regex to parse NMAP output. I want the ip addresses which are up with the corresponding ports open. Now I've a very naive method of doing that: awk '/^Scanning .....................ports]/ {print substr ($2,1,15);}' results.txt awk '/^[0-9][0-9]/ {print substr($1,1,4);}' results.txt | awk -f awkcode.awk where awkcode.awk contains the code to extract numbers out of the substring. The first line prints all the ips that are up and 2nd gives me the ports. My problem is that I want them mapped to each other. Is there any way to do that? Even sed script would do.

  • String formatting [str.format()] with a dictionary having a key which is a str() of a number

    - by decimus phostle
    Python neophyte here. I was wondering if someone could help with the KeyError I am getting when using a dictionary for string interpolation in str.format. dictionary = {'key1': 'val1', '1': 'val2'} string1 = 'Interpolating {0[key1]}'.format(dictionary) print string1 The above works fine and yields: Interpolating val1 However doing the following: dictionary = {'key1': 'val1', '1': 'val2'} string2 = 'Interpolating {0[1]}'.format(dictionary) print string2 results in: Traceback (most recent call last): File "test.py", line 3, in <module> string2 = 'Interpolating {0[1]}'.format(dictionary) KeyError: 1L So the problem seems to be in the interpretation of the numeric key as a list index, IMHO. Is there any way to work around this? (i.e. convey that this is instead a dictionary key) TIA and apologies if this question has been asked before(couldn't find anything relevant with my search-fu).

  • Use of 'standalone parentheses'

    - by zaf
    I just answered a question where I advised removing parentheses around a statement and was asked why, to which I had no answer when I realised that it caused no errors/warnings. I could only cite bad practice. But maybe I'm the one missing something... I did my own tests: (print('!')); // Outputs '!' ((print('!!'))); // Outputs '!!' (1); // No output (qwerty); // No output (1==2); // No output (1=2); // Syntax error // etc... Can someone shed some light on whats going on and of what use are 'standalone parentheses'?

  • How do I do this in Python (File Manipulation)?

    - by ThinkCode
    I have a bunch of HTML files in HTML folder. Those HTML files have unicode characters which I solved by using filter(lambda x: x in string.printable, line). Now how do I write the changes back to the original file? What is the best way of doing it? Each HTML file is of 30 kb in size. 1 import os, string 2 3 for file in os.listdir("HTML/"): 4 print file 5 myfile = open('HTML/' + file) 6 fileList = myfile.readlines() 9 for line in fileList: 10 #print line 11 line = filter(lambda x: x in string.printable, line) 12 myfile.close()

  • name of the class that contains the method code

    - by kdlp
    I'm trying to find the name of the class that contains method code. In the example underneath I use self.__class__.__name__, but of course this returns the name of the class of which self is an instance and not class that contains the test() method code. b.test() will print 'B' while I would like to get 'A'. I looked into the inspect module documentation but did not find anything directly useful. class A: def __init__(self): pass def test(self): print self.__class__.__name__ class B(A): def __init__(self): A.__init__(self) a = A() b = B() a.test() b.test()

  • How to store and retrieve file in mongoengine?

    - by Seiverence
    I am attempting to store and retrieve file within mongodb, but am having issues with the retrieval. class Animal(Document): genus = StringField() family = StringField() photo = FileField() def get_file(): marmot = Animal.objects(genus='Marmota').first() photo = marmot.photo.read() content_type = marmot.photo.content_type print marmot.family # Prints out "Sciuridae" print content_type # Gives me an error, as content_type is "None" def save_file(): marmot = Animal( genus='Marmota', family='Sciuridae') marmot_photo = open('marmot.jpg', 'r') marmot.photo = marmot_photo marmot.photo.content_type = 'image/jpeg' marmot.save() When I check mongodb, it appears the document does save after the save_file, but when I call get_file, it appears the content_type is "None"? Am I saving and retrieving the file correctly? If not, whats wrong with the code? NOTE: The issue appears only to occur in the Windows environment. When run on linux, it works fine... very confused.

  • Why do dicts of defaultdict(int)'s use so much memory? (and other simple python performance question

    - by dukhat
    import numpy as num from collections import defaultdict topKeys = range(16384) keys = range(8192) table = dict((k,defaultdict(int)) for k in topKeys) dat = num.zeros((16384,8192), dtype="int32") print "looping begins" #how much memory should this use? I think it shouldn't use more that a few #times the memory required to hold (16384*8192) int32's (512 mb), but #it uses 11 GB! for k in topKeys: for j in keys: dat[k,j] = table[k][j] print "done" What is going on here? Furthermore, this similar script takes eons to run compared to the first one, and also uses an absurd quantity of memory. topKeys = range(16384) keys = range(8192) table = [(j,0) for k in topKeys for j in keys] I guess python ints might be 64 bit ints, which would account for some of this, but do these relatively natural and simple constructions really produce such a massive overhead? I guess these scripts show that they do, so my question is: what exactly is causing the high memory usage in the first script and the long runtime and high memory usage of the second script and is there any way to avoid these costs?

  • Python . How to get rid of '\r' in string?

    I have an excel file that I converted to a text file with a list of numbers. test = 'filelocation.txt' in_file = open(test,'r') for line in in_file: print line 1.026106236 1.660274766 2.686381002 4.346655769 7.033036771 1.137969254 a = [] for line in in_file: a.append(line) print a '1.026106236\r1.660274766\r2.686381002\r4.346655769\r7.033036771\r1.137969254' I wanted to assign each value (in each line) to an individual element in the list. Instead it is creating one element separated by \r . i'm not sure what \r is but why is putting these into the code ? I think I know a way to get rid of the \r from the string but i want to fix the problem from the source

  • trying to work through a list in sections

I now need to iterate through this to work on each "group" at a time. the data is [name, group, data1, data2, data3, data4].

  • Why does Cacti keep waiting for dead poller processes?

    - by Oliver Salzburg
    sorry for the length I am currently setting up a new Debian (6.0.5) server. I put Cacti (0.8.7g) on it yesterday and have been battling with it ever since. Initial issue The initial issue I was observing, was that my graphs weren't updating. So I checked my cacti.log and found this concerning message: POLLER: Poller[0] Maximum runtime of 298 seconds exceeded. Exiting. That can't be good, right? So I went checking and started poller.php myself (via sudo -u www-data php poller.php --force). It will pump out a lot of message (which all look like what I would expect) and then hang for a minute. After that 1 minute, it will loop the following message: Waiting on 1 of 1 pollers. This goes on for 4 more minutes until the process is forcefully ended for running longer than 300s. So far so good I went on for a good hour trying to determine what poller might still be running, until I got to the conclusion that there simply is no running poller. Debugging I checked poller.php to see how that warning is issued and why. On line 368, Cacti will retrieve the number of finished processes from the database and use that value to calculate how many processes are still running. So, let's see that value! I added the following debug code into poller.php: print "Finished: " . $finished_processes . " - Started: " . $started_processes . "\n"; Result This will print the following within seconds of starting poller.php: Finished: 0 - Started: 1 Waiting on 1 of 1 pollers. Finished: 1 - Started: 1 So the values are being read and are valid. Until we get to the part where it keeps looping: Finished: - Started: 1 Waiting on 1 of 1 pollers. Suddenly, the value is gone. Why? Putting var_dump() in there confirms the issue: NULL Finished: - Started: 1 Waiting on 1 of 1 pollers. The return value is NULL. How can that be when querying SELECT COUNT()...? (SELECT COUNT() should always return one result row, shouldn't it?) More debugging So I went into lib\database.php and had a look at that db_fetch_cell(). A bit of testing confirmed, that the result set is actually empty. So I added my own database query code in there to see what that would do: $finished_processes = db_fetch_cell("SELECT count(*) FROM poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'"); print "Finished: " . $finished_processes . " - Started: " . $started_processes . "\n"; $mysqli = new mysqli("localhost","cacti","cacti","cacti"); $result = $mysqli->query("SELECT COUNT(*) FROM poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00';"); $row = $result->fetch_assoc(); var_dump( $row ); This will output Finished: - Started: 1 array(1) { ["COUNT(*)"]=> string(1) "2" } Waiting on 1 of 1 pollers. So, the data is there and can be accessed without any problems, just not with the method Cacti is using? Double-check that! I enabled MySQL logging to make sure I'm not imagining things. Sure enough, when the error message is looped, the cacti.log reads as if it was querying like mad: 06/29/2012 08:44:00 PM - CMDPHP: Poller[0] DEVEL: SQL Cell: "SELECT count(*) FROM cacti.poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'" 06/29/2012 08:44:01 PM - CMDPHP: Poller[0] DEVEL: SQL Cell: "SELECT count(*) FROM cacti.poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'" 06/29/2012 08:44:02 PM - CMDPHP: Poller[0] DEVEL: SQL Cell: "SELECT count(*) FROM cacti.poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'" But none of these queries are logged my MySQL. Yet, when I add my own database query code, it shows up just fine. What the heck is going on here?

  • BIND DNS Master with Zerigo Slaves - BIND won't update the slave servers

    - by Anthony
    I've tried to resolve this myself and have looked through Google and Stack but haven't found the answer I'm looking for. Currently on a VPS server I have BIND DNS installed as a MASTER DNS Server. I use Zerigo's DNS service as SLAVE servers for public use: The Master doesn't receive queries - It's job is to simply create and modify DNS entries locally of which the SLAVE use to serve. Here is an excerpt of the BIND log, I set it to INFO event logging: 14-Apr-2012 23:00:00.234 general: info: received control channel command 'reload' 14-Apr-2012 23:00:00.234 general: info: loading configuration from 'C:\DNS\BIND\etc\named.conf' 14-Apr-2012 23:00:00.234 general: info: using default UDP/IPv4 port range: [1024, 65535] 14-Apr-2012 23:00:00.234 general: info: using default UDP/IPv6 port range: [1024, 65535] 14-Apr-2012 23:00:00.250 general: info: reloading configuration succeeded 14-Apr-2012 23:00:00.250 general: info: reloading zones succeeded 14-Apr-2012 23:16:22.750 xfer-out: info: client 174.36.24.251#47135: transfer of 'ajmakeup.com/IN': AXFR started 14-Apr-2012 23:16:22.750 xfer-out: info: client 174.36.24.251#47135: transfer of 'ajmakeup.com/IN': AXFR ended 14-Apr-2012 23:16:23.015 xfer-out: info: client 68.71.141.22#36212: transfer of 'ajmakeup.com/IN': AXFR started 14-Apr-2012 23:16:23.031 xfer-out: info: client 68.71.141.22#36212: transfer of 'ajmakeup.com/IN': AXFR ended As you can see there is no problem with Zerigo's DNS servers requesting new DNS data, when I force a reload that is; I don't believe, as per the way they are set as SLAVE, that they poll for changes. However the problem is the other way; the MASTER is not updating the SLAVE servers when reload is run (on the MASTER); it is a batch on a 15 minute timer. Below is my NAMED.CONF: key "rndc-key" { algorithm hmac-md5; secret "REMOVED FOR SECURITY"; }; acl "trusted" { 174.36.24.251/32; 68.71.141.22/32; localhost; }; options { version "not currently available"; directory "C:\DNS\BIND\etc"; allow-query { trusted; }; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; }; }; logging{ channel simple_log { file "C:\DNS\BIND\logging\bind.log" versions 3 size 5m; severity info; print-time yes; print-severity yes; print-category yes; }; category default{ simple_log; }; }; zone "ajmakeup.com" in { type master; file "c:\dns\BIND\zones\db.ajmakeup.com.txt"; allow-transfer { 174.36.24.251; 68.71.141.22; }; allow-update { none; }; }; Does my problem have something to do with 'allow-query' under options? You will notice that 'allow-transfer' is set explicitly on each DNS zone. In case you need it here is my RNDC.CONF: key "rndc-key" { algorithm hmac-md5; secret "REMOVED FOR SECURITY"; }; options { default-key "rndc-key"; default-server 127.0.0.1; default-port 953; }; server localhost { key "rndc-key"; }; Note: I am using WebsitePanel as my hosting panel and is such why it creates the zone enteries the way it does. Although I know I can change this behaviour, I do not wish to do so nor do I believe is the root of the problem. Thanks for your help.

  • Call to daemon in a /etc/init.d script is blocking, not running in background

    - by tony
    I have a Perl script that I want to daemonize. Basically this perl script will read a directory every 30 seconds, read the files that it finds and then process the data. To keep it simple here consider the following Perl script (called synpipe_server, there is a symbolic link of this script in /usr/sbin/) : #!/usr/bin/perl use strict; use warnings; my $continue = 1; $SIG{'TERM'} = sub { $continue = 0; print "Caught TERM signal\n"; }; $SIG{'INT'} = sub { $continue = 0; print "Caught INT signal\n"; }; my $i = 0; while ($continue) { #do stuff print "Hello, I am running " . ++$i . "\n"; sleep 3; } So this script basically prints something every 3 seconds. Then, as I want to daemonize this script, I've also put this bash script (also called synpipe_server) in /etc/init.d/ : #!/bin/bash # synpipe_server : This starts and stops synpipe_server # # chkconfig: 12345 12 88 # description: Monitors all production pipelines # processname: synpipe_server # pidfile: /var/run/synpipe_server.pid # Source function library. . /etc/rc.d/init.d/functions pname="synpipe_server" exe="/usr/sbin/synpipe_server" pidfile="/var/run/${pname}.pid" lockfile="/var/lock/subsys/${pname}" [ -x $exe ] || exit 0 RETVAL=0 start() { echo -n "Starting $pname : " daemon ${exe} RETVAL=$? PID=$! echo [ $RETVAL -eq 0 ] && touch ${lockfile} echo $PID > ${pidfile} } stop() { echo -n "Shutting down $pname : " killproc ${exe} RETVAL=$? echo if [ $RETVAL -eq 0 ]; then rm -f ${lockfile} rm -f ${pidfile} fi } restart() { echo -n "Restarting $pname : " stop sleep 2 start } case "$1" in start) start ;; stop) stop ;; status) status ${pname} ;; restart) restart ;; *) echo "Usage: $0 {start|stop|status|restart}" ;; esac exit 0 So, (if I have well understood the doc for daemon) the Perl script should run in the background and the output should be redirected to /dev/null if I execute : service synpipe_server start But here is what I get instead : [root@master init.d]# service synpipe_server start Starting synpipe_server : Hello, I am running 1 Hello, I am running 2 Hello, I am running 3 Hello, I am running 4 Caught INT signal [ OK ] [root@master init.d]# So it starts the Perl script but runs it without detaching it from the current terminal session, and I can see the output printed in my console ... which is not really what I was expecting. Moreover, the PID file is empty (or with a line feed only, no pid returned by daemon). Does anyone have any idea of what I am doing wrong ? EDIT : maybe I should say that I am on a Red Hat machine. Scientific Linux SL release 5.4 (Boron) Would it do the job if instead of using the daemon function, I use something like : nohup ${exe} >/dev/null 2>&1 & in the init script ?

  • ScriptAlias makes requests match too many Location blocks. What is going on?

    - by brain99
    We wish to restrict access on our development server to those users who have a valid SSL Client certificate. We are running Apache 2.2.16 on Debian 6. However, for some sections (mainly git-http, setup with gitolite on https://my.server/git/) we need an exception since many git clients don't support SSL client certificates. I have succeeded in requiring client cert authentication for the server, and in adding exceptions for some locations. However, it seems this does not work for git. The current setup is as follows: SSLCACertificateFile ssl-certs/client-ca-certs.crt <Location /> SSLVerifyClient require SSLVerifyDepth 2 </Location> # this works <Location /foo> SSLVerifyClient none </Location> # this does not <Location /git> SSLVerifyClient none </Location> I have also tried an alternative solution, with the same results: # require authentication everywhere except /git and /foo <LocationMatch "^/(?!git|foo)"> SSLVerifyClient require SSLVerifyDepth 2 </LocationMatch> In both these cases, a user without client certificate can perfectly access my.server/foo/, but not my.server/git/ (access is refused because no valid client certificate is given). If I disable SSL client certificate authentication completely, my.server/git/ works ok. The ScriptAlias problem Gitolite is setup using the ScriptAlias directive. I have found that the problem occurs with any similar ScriptAlias: # Gitolite ScriptAlias /git/ /path/to/gitolite-shell/ ScriptAlias /gitmob/ /path/to/gitolite-shell/ # My test ScriptAlias /test/ /path/to/test/script/ Note that /path/to/test/script is a file, not a directory, the same goes for /path/to/gitolite-shell/ My test script simply prints out the environment, super simple: #!/usr/bin/perl print "Content-type:text/plain\n\n"; print "TEST\n"; @keys = sort(keys %ENV); foreach (@keys) { print "$_ => $ENV{$_}\n"; } It seems that if I go to https://my.server/test/someLocation, that any SSLVerifyClient directives are being applied which are in Location blocks that match /test/someLocation or just /someLocation. If I have the following config: <LocationMatch "^/f"> SSLVerifyClient require SSLVerifyDepth 2 </LocationMatch> Then, the following URL requires a client certificate: https://my.server/test/foo. However, the following URL does not: https://my.server/test/somethingElse/foo Note that this only seems to apply for SSL configuration. The following has no effect whatsoever on https://my.server/test/foo: <LocationMatch "^/f"> Order allow,deny Deny from all </LocationMatch> However, it does block access to https://my.server/foo. This presents a major problem for cases where I have some project running at https://my.server/project (which has to require SSL client certificate authorization), and there is a git repository for that project at https://my.server/git/project which cannot require a SSL client certificate. Since the /git/project URL also gets matched agains /project Location blocks, such a configuration seems impossible given my current findings. Question: Why is this happening, and how do I solve my problem? In the end, I want to require SSL Client certificate authorization for the whole server except for /git and /someLocation, with as minimal configuration as possible (so I don't have to modify the configuration each time something new is deployed or a new git repository is added). Note: I rewrote my question (instead of just adding more updates at the bottom) to take into account my new findings and hopefully make this more clear.

  • The Unspoken Truth About Managing Geeks

    - by Malcolm Anderson
    Late last year, Jeff Ello wrote a great article for cio magazine entitled "The Unspoken Truth About Managing Geeks" (http://www.cio.com/article/501697/The_Unspoken_Truth_About_Managing_Geeks)   If you are a non-geek managing geeks you will find this article enlightening.  It doesn't provide much in the way of soltutions, but it does show you how you can stop digging the hole that you're in, deeper than it already is.   In the event that you are a geek with a manager that just doesn't get it, then just print out this sleek little 4 page article and drop it in your managers in-basket.
