  • Emacs check syntax of file before saving

    - by astropanic
    How I can prevent Emacs from saving my buffer when it contains syntax errors ? It would by especially useful for editing source code. I'm writing some source code into the buffer, hit C-x C-s and Emacs should position the cursor on the line containing the error. I'm correcting the error, hit the save command again, and Emacs should save the file.

  • MySQL: updating a row and deleting the original in case it becomes a duplicate

    - by Silvio Donnini
    I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

  • Self-type mismatch in Scala

    - by Alexey Romanov
    Given this: abstract class ViewPresenterPair { type V <: View type P <: Presenter trait View {self: V => val presenter: P } trait Presenter {self: P => var view: V } } I am trying to define an implementation in this way: case class SensorViewPresenter[T] extends ViewPresenterPair { type V = SensorView[T] type P = SensorPresenter[T] trait SensorView[T] extends View { } class SensorViewImpl[T](val presenter: P) extends SensorView[T] { presenter.view = this } class SensorPresenter[T] extends Presenter { var view: V } } Which gives me the following errors: error: illegal inheritance; self-type SensorViewPresenter.this.SensorView[T] does not conform to SensorViewPresenter.this.View's selftype SensorViewPresenter.this.V trait SensorView[T] extends View { ^ <console>:13: error: type mismatch; found : SensorViewPresenter.this.SensorViewImpl[T] required: SensorViewPresenter.this.V presenter.view = this ^ <console>:16: error: illegal inheritance; self-type SensorViewPresenter.this.SensorPresenter[T] does not conform to SensorViewPresenter.this.Presenter's selftype SensorViewPresenter.this.P class SensorPresenter[T] extends Presenter { ^ I don't understand why. After all, V is just an alias for SensorView[T], and the paths are the same, so how can it not conform?

  • While submitting app to iOS App Store, "Unable to unzip application"

    - by Ivan Vucica
    I've successfully submitted "Product Name" to App Store. However, submitting "Product Name Lite", I keep getting the error "Unable to unzip application" in both Application Loader and built-in Xcode's uploader. Error persists even after eliminating spaces from the product name; in fact, I don't think there's whitespace anywhere in the app or the plist anymore. What might be causing this "highly descriptive" error? I'm using Xcode 3.2.5. Attempting to clean, build, and build&archive did not help.

  • Cannot create Hyper-V Virtual Machine - General Access Denied 0x80070005

    - by Vazgen
    I have the standalone Hyper-V Server 2012 running and I'm trying to create the first VM on it but I'm getting the following error: From my research, this error comes up with something related to the Intel IPMI driver but I have an Asus motherboard so I didn't think it was the problem. However, I ran the ResetAccess.exe fix anyways and to no surprise it said something like "This version of Windows does not require this fix". Thank you

  • valid json still fails on IE with jquery's ajax or getJSON callbacks

    - by lock
    everytime my page loads, im supposed to create a datatable (also a jquery plugin) but when im fetching the contents, using .ajax or .getJSON always goes straight ahead to the error function, without even telling me what went wrong inside the callback $.ajax({ cache: false, type: "POST", url: oSettings.sAjaxSource, data: {'newdate' : date}, contentType: "application/json; charset=utf-8", dataType: "json", success: function(json) { console.log('retrieving json data'); }, error: function() { console.log("An error has occurred. Please try again."); } }); that's the actual code with the callback stripped for security purposes... this works fine in firefox which actually executes what's on the callback function but IE simply fails and proceeds to writing my log i've read alot that the primary reason the JSON calls fails for IE is whenever there are trailing commas or simply malformed JS but i used JSONLint already and verified that my json object is a valid one :(

  • msvsmon is locking up my pdbs

    - by Sam Saffron
    During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

  • Django + WebKit = Broken pipe

    - by Saosin
    I'm running the Django 1.2 development server and I get these Broken Pipe error messages whenever I load a page from it with Chrome or Safari. My co-worker is getting the error as well when he loads a page from his dev server. We don't have these errors when using Opera or Firefox.

  • Django and ajax image file upload errors and csrf

    - by sharkfin
    I tried out Alex Kuhl's ajax script to upload images to Django 1.4. My first question is why I'm getting an empty page with firebug telling me I have two errors: fileuploader.js (line 4): syntax error <!DOCTYPE html> In my template html: qq is not defined var uploader = new qq.FileUploader( { Here is my entire html file for it: http://pastebin.com/NjbV5gMn This post suggests that either some script has 404'd or the src attribute is empty, which would cause the doctype error. But that doesn't seem to be the case here. As for why qq is not defined, I'm not sure what is wrong. Django can clearly find the fileuploader.js just fine from my static folder. My second question is why the ajax code uses {{ csrf_token }} instead of {% csrf_token %}. But if I use {% csrf_token %}, I get the firebug error: missing } after property list 'csrf_token': '<div style='display:none'<input type='hidden' name='csrfmiddlewaretoken' value='Cx0zFFak6OLgrHiAnFa3k4BPDmn4BgoT' /</div',

  • How to add the ImageMagick install to my path on Ubuntu

    - by Josh
    I have had been on a roller coaster trying to get ImageMagick to work on my Ubuntu slice. I Whenever I try to upload an image I get the following error: /tmp/stream.1170.0 is not recognized by the 'identify' command. If I type 'which identify' I get: /usr/local/bin/identify If I run '/usr/local/bin/identify' or just 'identify', I get the following error: /usr/local/bin/identify: error while loading shared libraries: libMagickCore.so.3: cannot open shared object file: No such file or directory If I run '/usr/bin/identify', ImageMagick is run just fine. How can I set my path to where when Paperclip runs the identify command, it points to /usr/bin/identify? Thanks. p.s. I have tried adding this to paperclip.rb: Paperclip.options[:command_path] = '/usr/bin' and Paperclip.options[:command_path] = '/usr/local/bin'

  • logrotate isn't rotating a particular log file (and i think it should be)

    - by Max Williams
    Hi all. For a particular app, i have log files in two places. One of the places has just one log file that i want to use with logrotate, for the other location i want to use logrotate on all log files in that folder. I've set up an entry called millionaire-staging in /etc/logrotate.d and have been testing it by calling logrotate -f millionaire-staging. Here's my entry: #/etc/logrotate.d/millionaire-staging compress rotate 1000 dateext missingok sharedscripts copytruncate /var/www/apps/test.millionaire/log/staging.log { weekly } /var/www/apps/test.millionaire/shared/log/*log { size 40M } So, for the first folder, i want to rotate weekly (this seems to have worked fine). For the other, i want to rotate only when the log files get bigger than 40 meg. When i look in that folder (using the same locator as in the logrotate config), i can see a file in there that's 54M and which hasn't been rotated: $ ls -lh /var/www/apps/test.millionaire/shared/log/*log -rw-r--r-- 1 www-data root 33M 2010-12-29 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 /var/www/apps/test.millionaire/shared/log/test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stderr.log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 /var/www/apps/test.millionaire/shared/log/unicorn.stdout.log Some of the other log files in that folder have been rotated though: $ ls -lh /var/www/apps/test.millionaire/shared/log total 91M -rw-r--r-- 1 www-data root 33M 2010-12-29 15:05 test.millionaire.charanga.com.access-log -rw-r--r-- 1 www-data root 54M 2010-09-10 16:57 test.millionaire.charanga.com.debug-log -rw-r--r-- 1 www-data root 53K 2010-12-14 15:48 test.millionaire.charanga.com.error-log -rw-r--r-- 1 www-data root 3.8M 2010-12-29 14:30 test.millionaire.charanga.com.ssl.access-log -rw-r--r-- 1 www-data root 16K 2010-12-17 15:00 test.millionaire.charanga.com.ssl.error-log -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stderr.log -rw-r--r-- 1 deploy deploy 41K 2010-12-29 11:03 unicorn.stderr.log-20101229.gz -rw-r--r-- 1 deploy deploy 0 2010-12-29 14:49 unicorn.stdout.log -rw-r--r-- 1 deploy deploy 1.1K 2010-10-15 11:05 unicorn.stdout.log-20101229.gz I think what might have happened is that i first ran this config with a pattern matching *.log, and that means it only rotated the two files that ended in .log (as opposed to -log). Then, when i changed the config and ran it again, it won't do any more since it think's its already had its weekly run, or something. Can anyone see what i'm doing wrong? Is it to do with those top folders being owned by root rather than deploy do you think? thanks, max

  • Tomcat not showing Spring Context initialization errors when running from Eclipse WTP

    - by SourceRebels
    Hi all, Im working with Eclipse Galileo (WTP), Spring 2.5.6-SEC01 and Apache Tomcat 5.5.28. When I run my application from Eclipse, I'm able to see Tomcat standard output and error from the console view. When there is a Spring initialization error (ex: malformed spring XML) I'm not able to see the error message or the stacktrace at the Console view. Anyone found before a problem like this? how you solve it? Thanks in advance, I'm getting mad :-) Edited: I'm seeing all Tomcat startup messages and my System.out.println and System.err.println messages in Eclipse Console. I also try to pass this two system properties to my Tomcat Server: -Djava.util.logging.manager="org.apache.juli.ClassLoaderLogManager" -Djava.util.logging.config.file="C:\apache-tomcat-5.5.28\conf\logging.properties"

  • Solver Add-in not loading correctly

    - by Paul
    When I try to open solver from inside excel 2010, I get the error message: "Solver: An unexpected internal error occurred, or available memory was exhausted." The only way I have been able to get Solver to work is by going to "C:\Program Files\Microsoft Office\Office14\Library\SOLVER\", and just opening the file called "SOLVER.xlam". If I open excel through that file, the program works fine. Is there a way to solve this issue?

  • Permission denied - /tmp/.ruby_inline/Inline_ImageScience_cdab.c

    - by Ikaros
    I have a Ruby on Rails app that I've recently deployed to a remote server (Ubuntu 9.10, nginx, passenger, ruby-enterprise) and I'm getting the error (works fine locally): Permission denied - /var/www/project_name/tmp/.ruby_inline/Inline_ImageScience_cdab.c First, the folder /tmp/.ruby_inline/ is empty - should it be? Is it trying to create Inline_ImageScience_cdab.c or read it? I think I have all the required gems installed: 'gem list' shows image_science and RubyInline installed. libfreeimage3 and libfreeimage-dev are also installed. I've run chmod 755 on /tmp/.ruby_inline/ to match the permissions on surrounding folders but I cannot go any higher than that, however, or I get another error: /var/www/project_name/tmp/.ruby_inline is insecure (40777). It may not be group or world writable. Exiting. And I guess second, why am I getting this error? :) Thanks

  • "[object Object]" passed instead of the actual object as parameter

    - by Andrew Latham
    I am using Heroku with a Ruby on Rails application, and running from Safari. I have the following Ajax call: $.ajax({ type : 'POST', url : '/test_page', data : {stuff: arr1}, dataType : 'script' }); arr1 is supposed to be an array of objects. There's a console.log right before that, and it is: [Object, Object, Object, Object, Object, ...] However, I got an error on the server side when I made this ajax call. The logs showed 2012-10-01T03:13:34+00:00 app[web.1]: Parameters: {"stuff"=>"[object Object]"} 2012-10-01T03:13:34+00:00 app[web.1]: WARNING: Can't verify CSRF token authenticity 2012-10-01T03:13:34+00:00 app[web.1]: NoMethodError (undefined method `to_hash' for "[object Object]":String): 2012-10-01T03:13:34+00:00 app[web.1]: Completed 500 Internal Server Error in 1ms I'm unable to replicate the error. It's really confusing to me - what would cause that string to sometimes be passed to the server instead of the object?

  • Eclipse Problems View doesn't show Errors

    - by Jack
    [Note: There is another thread about this problem but it did not answer the question.] For one specific project in Eclipse, the problems view does not show errors. It shows warnings but it does not show errors. The other projects do show errors (and everything else). For that problematic project, I can see the red squiggly error line in the files. However, the directory structure does not show an error icon and the error is not populated in the Problems View. Any ideas?

  • Spring - disable bind exceptions (for a particular property)

    - by Walter White
    Hi all, In a web application I'm working on using Spring 2.5.6.SEC01, I essentially have an Integer field that takes a number to determine which page to scroll to. The requirements changed, and we no longer want to display an error message, but simply ignore the user's input if they enter an invalid number, say "adfadf". I was reading that you can do that via: TypeMismatch.property=Some New Error Message However, after having tried that, we are still getting the original error message: java.lang.Integer.TypeMismatch=... I only want to disable this message for that given property. How can I do that? I still want binding to occur automatically, I just don't want to hear about it now. Walter
