• Virtual folder for multiple sites

  - by Cups

  I am creating a very simple flat file CMS for small (multilingual) websites. The little file writing that goes on is handled by 4 scripts in a publicly available folder in each site named /edit. Given that I have 2 websites now working on that simple system: websiteA/index.php (etc) websiteA/edit/ websiteB/index.php (etc) websiteB/edit/ What is the best way of making that /edit folder "virtual" in order that these and each subsequent website owner can login to their view of /edit and yet the code only exists in one place. I do not want the website owners to have to login from a central website, but from their own /edit directory. I have already read about different solutions seemingly using the <Directory> directive in my httpd.conf declaration for each website, and also using straight mod_rewrite but admit to now becoming confused about some of the terminology. Each website has its own config file which contains path settings and so on. What in your opinion is the best way to handle this? EDIT In light of a reply, I suppose that given a virtual host directive such as this: <VirtualHost 00.00.00.00:80> DocumentRoot /var/www/html/websitea.com ServerName www.websitea.com ServerAlias websitea.com DirectoryIndex index.htm index.php CustomLog logs/websitea combined </VirtualHost> Is it possible to create an alias inside that directive for the folder websitea.com/edit ?

• Windows 7 permissions and Samba domain

  - by Nimzo

  I'm the main desktop support in an office of mixed MacOS and WinXp machines, about 60. I'm new to Windows 7. Currently our XP users are admins on their own machines, and my boss is wanting us to get away from that now that we're going to Windows 7 (64bit). My boss is largely absent from my day-to-day work, so I'm here looking for help =) I have numerous unattended .cmd scripts that we run from a server share, unattended software installs. Some run at login, some have to be run manually. With the NetworkAdmin account logged on to the computer, I am able to run the .cmd files and install stuff just fine. With my test account logged on (Power User), I cannot run the .cmd file - I get an Access Denied. When I change my test account to an Admin on the machine, I still get access denied. However, the test account can simply double-click the .exe and install the software just fine, as admin. Power User can't install anything. How do I fix it so that any power user or admin on the machine can run anything as long as it's on our shared software drive?

• How can I document and automate a system's configuration?

  - by Diomidis Spinellis

  Having a system's configuration represented by its current state is risky, inefficient, and opaque. At some point you may be left with an unsupported system and no upgrade path. Then configuring a new system compatible with the old is a process or trial and error. Furthermore, if at some point the system is damaged the only option is to go back to the most recent full backup, and try to remember what changes followed from that point. Also, the only way to create a system compatible with the original is through a complete dump/restore. Finally, in such a setup there's no way to know how you solved a particular problem; the only thing you can do is to look at the corresponding configuration files and try to guess what you changed to achieve the desired effect. Currently for each system I maintain, I keep a log file where I record all system administration activity, starting from the installation: installation options, added packages, changes in configuration files, updates, problem fixes etc. In theory this allows me to (manually) replay all changes to arrive at the current state, or to unroll an erroneous change by executing the reverse commands. However, this process is also inefficient, error-prone, and relies on human judgment. Another thing I've tried is to put /etc configuration files under version control with git. This helps me document the changes automatically and also apply them on a clean setup. But it's not without problems: git has to run under sudo, passwords and private keys may be stored in the repository, installed packages can't be meaningfully tracked, and git will have a fit if I try to extend this approach to all the system's directories. I've also thought about performing all changes through shell scripts or makefiles, but I think this process will require a lot of effort and will be fragile. Are there some better methods or tools that I'm missing?

• How do I fix a permissions problem with MS Distributed File System?

  - by charlesrandall

  I have a computer that is new, Windows 7, that is supposed to have access to particular network resources on a Distributed File System. However, despite all permissions being set correctly, I have consistent trouble accessing them. For instance, I'm supposed to be able to reach \company.org\main\subdir. All the permissions have been granted, only when I try to access it by name, it tells me I don't have permission to access \main. This is where the fun starts. If I ping company.org, get the IP, replace company.org by the IP, I can then access \IP\main\subdir without any problems at all. However we have a ton of scripts and build tools that access the network resource by name. My sysadmin has found that using MS's dfsutil.exe, we can fix it temporary using this sequence of commands: C:\dfsutil.exe /pktinfo C:\dfsutil.exe /PktFlush C:\dfsutil.exe /SpcFlush C:\dfsutil.exe /PurgeMupCache C:\dfsutil.exe /pktinfo After that, everything is great... until I reboot, or until some unspecified time later where suddenly I don't have access to \main\ anymore. Hoping to find a more permanent solution than waiting for it to break and running a batch file.

• Customizing tmux status to represent current working directory and files

  - by user69397

  I've been playing with this for a couple of days, so I'm sure I'm missing something simple. Love tmux. Using it for development and have so many windows I need a better way of distinguishing them in the status bar and in the buffer list. Seeing a list of "bash" and "vim" isn't really helpful at all. And since they're all on the same host - don't care about the hostname right now. I'd like to show the current working directory, and the file being worked on. For example when I view the list of buffers I currently see: (0) 0: vim [100x44] (1 panes) "murph" (1) 1: vim [100x44] (1 panes) "murph" (2) 2: bash- [100x44] (1 panes) "murph" (3) 3: bash* [100x44] (1 panes) "murph" Here's what I'd like to see 0:vim main.py ~/devl/project1 1:vim index.html ~/devl/samples/staticfiles 2:bash ~/devl/sandbox 3:bash ~/.vimrc I'd like to see similar info in the status bar for each individual window. While I am able to get PWD to show up in the status bar of a window, it's only the working directory from where tmux was launched. This isn't any help as I change directories. I'm hoping this can be done without a bunch of scripts. Thanks all.

• Debian 7 and PHP 5.4.4 error reporting

  - by milovan

  I use default php.ini and then in my PHP script (local.settings.php in Drupal) I simply set ini_set('error_reporting', 'E_ALL & ~E_NOTICE & ~E_STRICT'); According to documentation this means "show all messages minus notice and strict warnings". But in my case it still shows strict warnings! I have no idea why, because I clearly stated "~E_STRICT". If I comment it out then I see strict warnings. So it means that default from php.ini "E_ALL & ~E_DEPRECATED & ~E_STRICT" didn't do its job as it also has "~E_STRICT" but I still see strict warnings. On Debian 6 there was Suhoshin patch which was controlling usage of php_ini in PHP scripts. Especially when you try to get more memory than defined cap. Now on debian 7 there is no Suhoshin nor any other security element that might control php_ini. So what might cause php_ini not to be executed? Is there some new variable / setup / other that needs to be checked?

• Open source app to manage and run commands on cloud servers? [closed]

  - by Mark Theunissen

  I'm creating a SaaS platform, and I need a component / library that can create, delete and store the connection details for cloud servers. It also needs to support executing shell commands on these servers and returning the response to the caller. I want a central database of servers and their configuration, plus the ability to reach out and manage the servers via SSH execution of bash scripts. I don't want something that needs agents on every server like Chef. For example, this command is received by the hypothetical application: CREATE USER server = server12345 name = myuser It's translated into the following set of actions and executed by the app, which knows how to connect to server12345, and how to create a user on that server: $ ssh root@server12345 $ adduser myuser And returns the output from the shell: Added user myuser. I've done research on Google and can't quite quite find something that does this already. I've found: fabric This part handles the executing of the shell commands very elegantly, and can take multiple server definitions, but it's supposed to be a deployment tool so doesn't do everything that would be required above - for example, it doesn't have a daemon mode where it listens for commands - it expects to be executed on the shell. It also can't provide the central database functionality. libcloud This library can handle the server admin (CRUD) part, but doesn't have a command interface daemon either, and doesn't let you execute commands on the servers. I guess I need something that is a combination of libcloud, fabric and django for an API. Or something else that does that same thing regardless of language. Overmind Overmind is a GUI and wrapper around libcloud, but doesn't support the command execution part. What am I missing here?

• Stdin to powershell script

  - by Stefan

  I have a service running that can invoke an external process to modify a text stream before it is returned to the service. The text stream is handed from the service to the external process on stdout and the modified result is read from the service on stdin. The external process (command) can in other words be used as a text "filter". I would like to use a powershell script to modify the text stream. I can successfully launch a script from the service on win 2008r2 using the command "powershell -executionpolicy bypass -noninteractive ./myscript.ps1". I can make the script return text to the service on stdout using the write-host cmdlet. My problem is that I can't find a way to read the text on stdin in the script. Read-host doesn't seem to work as it requires an interactive shell. I would like to avoid writing the stdout from the service to a tmp file and read that file in the script as the service is multithreaded (can launch more than one external command at a time) and tmp file management (locking, unique filenames etc) is not desired. Is this possible or should I use for example Perl for this? Powershell seems compelling as it is preinstalled on all my win 2008 machines.

• Extending Programming Languages

  - by chpwn

  (Since I just posted this in another question, but my browser had to be annoying and submit it without content first, here it is again:) I'm a fan of clean code. I like my languages to be able to express what I'm trying to do, but I like the syntax to mirror that too. For example, I work on a lot of programs in Objective-C for jailbroken iPhones, which patch other code using the method_setImplementation() function of the runtime. Or, in pyobjc, I have to use the syntax UIView.initWithFrame_(), which is also pretty awful and unreadable with the way the method names are structured. In both cases, the language does not support this in syntax. I've found three basic ways that this is done: Insane macros. Take a look at this "CaptainHook", it does what I'm looking for in a usable way, but it isn't quite clean and is a major hack. There's also "Logos", which implements a very nice syntax, but is written in Perl parsing my code with a ton of regular expressions. This scares me. I like the idea of adding a %hook ClassName, but not by using regular expressions to parse C or Objective-C. Finally, there is Cycript. This is an extension to JavaScript which interfaces with the Objective-C runtime and allows you to use Objective-C style code in your JavaScript, and inject that into other processes. This is likely the cleanest as it actually uses a parser for the JavaScript, but I'm not a huge fan of that language in general. Basically, this is a two part question. Should, and how should, I create an extension to Python and Objective-C to allow me to do this? Is it worth writing a parser for my language to transform the syntax into something nicer, if it is only in a very specialized niche like this? Should I just live with the horrible syntax of the default Objective-C hooking or pyobjc?

• Reading excel files with xlrd

• How to find if an Oracle APEX session is expired

  - by Mathieu Longtin

  I have created a single-sign-on system for our Oracle APEX applications, roughly based on this tutorial: http://www.oracle.com/technology/oramag/oracle/09-may/o39security.html The only difference is that my master SSO login is in Perl, rather than another APEX app. It sets an SSO cookie, and the app can check if it's valid with a database procedure. I have noticed that when I arrive in the morning, the whole system doesn't work. I reload a page from the APEX app, it then sends me to the SSO page because the session was expired, I logon, and get redirected back to my original APEX app page. This usually works except first thing in the morning. It seems the APEX session is expired. In that case it seems to find the session, but then refuse to use it, and sends me back to the login page. I've tried my best to trace the problem. The "wwv_flow_custom_auth_std.is_session_valid" function returns true, so I'm assuming the session is valid. But nothing works until I remove the APEX session cookie. Then I can log back in easily. Anybody knows if there is another call that would tell me if the session is expired or not? Thanks

• Easy to use AutoHotkey/AutoIT alternatives for Linux

  - by Xeddy

  Hi all, I'm looking for recommendations for an easy-to-use GUI automation/macro platform for Linux. If you're familiar with AutoHotkey or AutoIT on Windows, then you know exactly the kind of features I need, with the level of complexity. If you aren't familiar, then here's a small code snippet of how easy it is to use AHK: InputBox, varInput, Please enter some random text... Run, notepad.exe WinWaitActive, Untitled - Notepad SendInput, %varInput% SendInput, !f{Up}{Enter}{Enter} WinWaitActive, Save SendInput, SomeRandomFile{Enter} MsgBox, Your text`, %varInput% has been saved using notepad! #n::Run, notepad.exe Now the above example, although a bit pointless, is a demo of the sort of functionality and simplicity I'm looking for. Here's an explanation for those who don't speak AHK: ----Start of Explanation of Code ---- Asks user to input some text and stores it in varInput Runs notepad.exe Waits till window exists and is active Sends the contents of varInput as a series of keystrokes Sends keystrokes to go to File - Exit Waits till the "Save" window is active Sends some more keystrokes Shows a Message Box with some text and the contents of a variable Registers a hotkey, Win+N, which when pressed executes notepad.exe ----End of Explanation---- So as you can understand, the features are quite obvious: Ability to easily simulate keyboard and mouse functions, read input, process and display output, execute programs, manipulate windows, register hotkeys, etc.. all being done without requiring any #includes, unnecessary brackets, class declarations etc. In short: Simple. Now I've played around a bit with Perl and Python, but its definitely no AHK. They're great for more advanced stuff, but surely, there has to be some tool out there for easy GUI automation? PS: I've already tried running AHK with Wine but sending keystrokes and hotkeys don't work.

• libdb4.6-dev vs libdb4.7-dev

  - by routinet

  I want to install PHP 5.3 on Ubuntu Intrepid. To install apxs, I need to install libaprutil1-dev, which depends on libdb4.6-dev. When I look at installing that, apt-get wants to remove the currently installed libdb-dev and libdb4.7-dev. Any advice on how to proceed? [root@server:/usr/local] #> apt-get -s install libaprutil1-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies: libaprutil1-dev: Depends: libdb4.6-dev but it is not going to be installed E: Broken packages [root@server:/usr/local] #> apt-get -s install libdb4.6-dev Reading package lists...

• What is the worst programming language you ever worked with? [closed]

  - by Ludwig Weinzierl

  If you have an interesting story to share, please post an answer, but do not abuse this question for bashing a language. We are programmers, and our primary tool is the programming language we use. While there is a lot of discussion about the best one, I'd like to hear your stories about the worst programming languages you ever worked with and I'd like to know exactly what annoyed you. I'd like to collect this stories partly to avoid common pitfalls while designing a language (especially a DSL) and partly to avoid quirky languages in the future in general. This question is not subjective. If a language supports only single character identifiers (see my own answer) this is bad in a non-debatable way. EDIT Some people have raised concerns that this question attracts trolls. Wading through all your answers made one thing clear. The large majority of answers is appropriate, useful and well written. UPDATE 2009-07-01 19:15 GMT The language overview is now complete, covering 103 different languages from 102 answers. I decided to be lax about what counts as a programming language and included anything reasonable. Thank you David for your comments on this. Here are all programming languages covered so far (alphabetical order, linked with answer, new entries in bold): ABAP, all 20th century languages, all drag and drop languages, all proprietary languages, APF, APL (1), AS400, Authorware, Autohotkey, BancaStar, BASIC, Bourne Shell, Brainfuck, C++, Centura Team Developer, Cobol (1), Cold Fusion, Coldfusion, CRM114, Crystal Syntax, CSS, Dataflex 2.3, DB/c DX, dbase II, DCL, Delphi IDE, Doors DXL, DOS batch (1), Excel Macro language, FileMaker, FOCUS, Forth, FORTRAN, FORTRAN 77, HTML, Illustra web blade, Informix 4th Generation Language, Informix Universal Server web blade, INTERCAL, Java, JavaScript (1), JCL (1), karol, LabTalk, Labview, Lingo, LISP, Logo, LOLCODE, LotusScript, m4, Magic II, Makefiles, MapBasic, MaxScript, Meditech Magic, MEL, mIRC Script, MS Access, MUMPS, Oberon, object extensions to C, Objective-C, OPS5, Oz, Perl (1), PHP, PL/SQL, PowerDynamo, PROGRESS 4GL, prova, PS-FOCUS, Python, Regular Expressions, RPG, RPG II, Scheme, ScriptMaker, sendmail.conf, Smalltalk, Smalltalk , SNOBOL, SpeedScript, Sybase PowerBuilder, Symbian C++, System RPL, TCL, TECO, The Visual Software Environment, Tiny praat, TransCAD, troff, uBasic, VB6 (1), VBScript (1), VDF4, Vimscript, Visual Basic (1), Visual C++, Visual Foxpro, VSE, Webspeed, XSLT The answers covering 80386 assembler, VB6 and VBScript have been removed.

• Getting past dates in HP-UX with ksh

  - by Alejandro Atienza Ramos

  Ok, so I need to translate a script from a nice linux & bash configuration to ksh in hp-ux. Each and every command expects a different syntax and i want to kill myself. But let's skip the rant. This is part of my script anterior=`date +"%Y%0m" -d '1 month ago'` I basically need to get a past date in format 201002. Never mind the thing that, in the new environment, %0m means "no zeroes", while actually in the other one it means "yes, please put that zero on my string". It doesn't even accept the "1 month ago". I've read the man date for HP-UX and it seems you just can't do date arithmetic with it. I've been looking around for a while but all i find are lengthy solutions. I can't quite understand that such a typical administrative task like adding dates needs so much fuss. Isn't there a way to convert my one-liner to, well, i don't know, another one? Come on, i've seen proposed solutions that used bc, had thirty plus lines and magic number all over the script. The simplest solutions seem to use perl... but i don't know how to modify them, as they're quite arcane. Thanks!

• Why can't I source my vimrc after installing vundle?

  - by John N

  I'm trying to get my Vim to update on the fly after editing vimrc. So I followed the instructions at Vimcast which basically source vimrc every time you hit save. But that doesn't work for some reason (when I save my vimrc it doesn't give any errors), so I decided to run source $HOME/.vimrc manually and here's what I got: -bash: Configuration file for vim set nocompatible : command not found -bash: Plugin Management { filetype off : command not found -bash: .vimrc: line 7: syntax error near unexpected token `(' -bash: .vimrc: line 7: ` call vundle#rc()' And here's my Vim info (I'm running Mac OS X 10.7.3): VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Jul 31 2011 19:27:29) Compiled by [email protected] Normal version without GUI.

• Decisions in teaching someone else to program: language selection

  - by Dinah

  My friend would like for me to guide her into learning programming. She's already proven enormous aptitude for thinking like a programmer but is scared of the idea of programming since in her mind it's relegated to some magical realm accessible only to smart people and trained computer scientists (ironically, I am neither but that's beside the point). My main question is the age-old and irritating question: which language should I chose? I've limited it down to these: PHP: dead simple to start with and I remember enough of the language to answer all novice questions. However, I can think of a million reasons why I wouldn't recommend this as a first language. The most diplomatic of which is that there's no desktop app option to which I would feel comfortable subjecting a novice. Python: supposed to be wonderful for beginners and generally everything I've heard about it screams that this is the correct choice. That's the problem: everything I've heard about it. I don't know it yet and have a lot of projects going on right now so I don't feel like learning it yet -- but I'm going to be the tech-support when any little thing goes wrong. I know there are tons of online resources but in the frustration of the moment, it's always going to be just me. C#: this is the language I'm most comfortable with so I know I can be good tech support. I also love this language and its versatility and community. The big drawback here is that I remember when I first learned it after doing mainly PHP, Perl, and JavaScript and I found the experience overwhelming. You are simultaneously learning: programming concepts, C# syntax, strong typing, OOP, and a complex powerful IDE with a bazillion options and buttons all over it.

• No coverage for runtime with Devel::Cover and ModPerl::Registry

  - by codeholic

  When I'm running Devel::Cover with ModPerl::Registry, I get no coverage info except for BEGIN blocks. When I'm running the same script with Devel::Cover from command line or as a CGI, everything works alright (obviously). How can I make Devel::Cover "see" my code being executed in the runtime? Here's Devel::Cover related stuff in my httpd.conf: MaxClients 1 PerlSetEnv DEVEL_COVER_OPTIONS -db,/tmp/cover_db,silent,1 PerlRequire /var/www/project/startup.pl Here's startup.pl: #!/usr/bin/perl use strict; use warnings; use Apache2::Directive (); use File::Basename (); use File::Find (); BEGIN { # Devel::Cover database must be writable by worker processes my $conftree = Apache2::Directive::conftree->as_hash; my $name = $conftree->{User} or die "couldn't find user in Apache config"; print "user=$name\n"; my $uid = getpwnam($name); defined $uid or die "couldn't determine uid by name"; no warnings 'redefine'; local $> = $uid; require Devel::Cover; my $old_report = \&Devel::Cover::report; *Devel::Cover::report = sub { local $> = $uid; $old_report->(@_) }; Devel::Cover->import; } 1; (As you may see, I made a monkey patch for Devel::Cover since startup.pl is being run by root, but worker processes run under a different user, and otherwise they couldn't read directories created by startup.pl. If you know a better solution, make a note, please.)

• Extending Python and Objective-C

  - by chpwn

  I'm a fan of clean code. I like my languages to be able to express what I'm trying to do, but I like the syntax to mirror that too. For example, I work on a lot of programs in Objective-C for jailbroken iPhones, which patch other code using the method_setImplementation() function of the runtime. Or, in PyObjC, I have to use the syntax UIView.initWithFrame_(), which is also pretty awful and unreadable with the way the method names are structured. In both cases, the language does not support this in syntax. I've found three basic ways that this is done: Insane macros. Take a look at this "CaptainHook", it does what I'm looking for in a usable way, but it isn't quite clean and is a major hack. There's also "Logos", which implements a very nice syntax, but is written in Perl parsing my code with a ton of regular expressions. This scares me. I like the idea of adding a %hook ClassName, but not by using regular expressions to parse C or Objective-C. Finally, there is Cycript. This is an extension to JavaScript which interfaces with the Objective-C runtime and allows you to use Objective-C style code in your JavaScript, and inject that into other processes. This is likely the cleanest as it actually uses a parser for the JavaScript, but I'm not a huge fan of that language in general. Should, and how should, I create an extension to Python and Objective-C to allow me to do this? Is it worth writing a parser for my language to transform the syntax into something nicer, if it is only in a very specialized niche like this? Should I just live with the horrible syntax of the default Objective-C hooking or PyObjC?

• Is Berkeley DB XML a viable database backend?

  - by w00t

  Apparently, BDB-XML has been around since at least 2003 but I only recently stumbled upon it on Oracle's website: Berkeley DB XML. Here's the blurb: Oracle Berkeley DB XML is an open source, embeddable XML database with XQuery-based access to documents stored in containers and indexed based on their content. Oracle Berkeley DB XML is built on top of Oracle Berkeley DB and inherits its rich features and attributes. Like Oracle Berkeley DB, it runs in process with the application with no need for human administration. Oracle Berkeley DB XML adds a document parser, XML indexer and XQuery engine on top of Oracle Berkeley DB to enable the fastest, most efficient retrieval of data. To me it seems that the underlying ideas are technically sound and probably more mature than the newer document-based DBs like CouchDB or MongoDB. It has support for C, C++, Ruby and Perl, as far as I can determine. It even has HA-capabilities like automatic replication using a master/slave model with automatic election. However, I can't seem to find any projects that use it. Is there something fundamentally wrong with it? Is the license too onerous? Is it too complicated? Why is it not being used?

• Apache and backslashes in mod_rewrite

  - by NuCalTone

  I want to process all incoming requests through a single script (index.php in web-root). So, the following is what currently happens: http://localhost/foo/bar/baz Is routed by Apache (through .htaccess) to: http://localhost/index.php?url=foo/bar/baz This works well, however, in Firefox I am able to do this: http://localhost/foo\ - notice the backslash. And Apache, instead of doing: /index.php?url=foo\ Emits a generic error page saying: Object not found! The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again. If you think this is a server error, please contact the webmaster. Error 404 localhost Apache/2.2.14 (Win32) DAV/2 mod_ssl/2.2.14 OpenSSL/0.9.8l mod_autoindex_color PHP/5.3.1 mod_apreq2-20090110/2.7.1 mod_perl/2.0.4 Perl/v5.10.1 Directly going to: http://localhost/index.php?url=foo\ works without issues, however. All the sites that I've seen on the internet seem to be able to handle backslashes gracefully (e.g., http://stackoverflow.com/tags/php\\\\\). I consider this behavior a bug and I want to force Apache to forward backslashes correctly. Here's my .htaccess file in its entirety: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [L] How can I make this work properly?

• scraping text from multiple html files into a single csv file

  - by Lulu

  I have just over 1500 html pages (1.html to 1500.html). I have written a code using Beautiful Soup that extracts most of the data I need but "misses" out some of the data within the table. My Input: e.g file 1500.html My Code: #!/usr/bin/env python import glob import codecs from BeautifulSoup import BeautifulSoup with codecs.open('dump2.csv', "w", encoding="utf-8") as csvfile: for file in glob.glob('*html*'): print 'Processing', file soup = BeautifulSoup(open(file).read()) rows = soup.findAll('tr') for tr in rows: cols = tr.findAll('td') #print >> csvfile,"#".join(col.string for col in cols) #print >> csvfile,"#".join(td.find(text=True)) for col in cols: print >> csvfile, col.string print >> csvfile, "===" print >> csvfile, "***" Output: One CSV file, with 1500 lines of text and columns of data. For some reason my code does not pull out all the required data but "misses" some data, e.g the Address1 and Address 2 data at the start of the table do not come out. I modified the code to put in * and === separators, I then use perl to put into a clean csv file, unfortunately I'm not sure how to work my code to get all the data I'm looking for!

• Working around MySQL error "Deadlock found when trying to get lock; try restarting transaction"

  - by Anon Guy

  Hi all: I have a MySQL table with about 5,000,000 rows that are being constantly updated in small ways by parallel Perl processes connecting via DBI. The table has about 10 columns and several indexes. One fairly common operation gives rise to the following error sometimes: DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction at Db.pm line 276. The SQL statement that triggers the error is something like this: UPDATE file_table SET a_lock = 'process-1234' WHERE param1 = 'X' AND param2 = 'Y' AND param3 = 'Z' LIMIT 47 The error is triggered only sometimes. I'd estimate in 1% of calls or less. However, it never happened with a small table and has become more common as the database has grown. Note that I am using the a_lock field in file_table to ensure that the four near-identical processes I am running do not try and work on the same row. The limit is designed to break their work into small chunks. I haven't done much tuning on MySQL or DBD::mysql. MySQL is a standard Solaris deployment, and the database connection is set up as follows: my $dsn = "DBI:mysql:database=" . $DbConfig::database . ";host=${DbConfig::hostname};port=${DbConfig::port}"; my $dbh = DBI->connect($dsn, $DbConfig::username, $DbConfig::password, { RaiseError => 1, AutoCommit => 1 }) or die $DBI::errstr; I have seen online that several other people have reported similar errors and that this may be a genuine deadlock situation. I have two questions: What exactly about my situation is causing the error above? Is there a simple way to work around it or lessen its frequency? For example, how exactly do I go about "restarting transaction at Db.pm line 276"? Thanks in advance.
