    MySQL in WordPress 3.9 – Implications for Plugin Authors 

    If you’re a plugin developer and you have a plugin using any of the php mysql functions directly, then you might start to see breakage in WordPress 3.9.

    See, the php mysql extension is very old. As of PHP 5.5, it’s also deprecated and will very likely not be receiving further updates.

    So starting in WordPress 3.9, if PHP 5.5 is being used, the built in WPDB class will switch to using the mysqli extension instead.

    What this means for your plugin is that if you’re using any mysql_* functions directly, and somebody tries to use your plugin on a WordPress 3.9 + PHP 5.5 system, then all your database code will no longer work properly. Since the mysql functions are no longer being used in such a case by WordPress, then there is no longer an implicit database connection available to these function calls.

    Instead of using a direct database connection, you can switch to using the global $wpdb instance of the WPDB class to access the database. @pento gives a great rundown on what functions to use as drop-in replacements on this make/core post: http://make.wordpress.org/core/2014/04/07/mysql-in-wordpress-3-9/

    Now, as this is currently limited to PHP 5.5 and up only, the amount of breakage will likely be very minor. Our stats currently show that PHP 5.5 is being used on less than 1% of installations. Nevertheless, hosts are starting to upgrade PHP versions more and more frequently. This number is thus expected to grow over the next year or two. So before your users start having broken sites, please, take the time to switch your plugins over to the WPDB based methods. This will ensure future compatibility and minimal breakage.

    WordPress will always maintain backward compatibility in its own functions, so using them ensures that you’ll be good for the forseeable future, no matter what database methods are being used internally.

      Glad to hear this. mysqli is much better.

      We use PHP 5.5 and mysqli on all sites. I hope WordPress site’s running PHP 5.5 and mysqli will run faster soon. :-)

    Plugin Screenshots Downloading? 

    It’s not you, it’s SVN. And you.

    The tl;dr is that the MIME Types on your images aren’t correct. Per Otto:

    On Windows, using TortoiseSVN, you can right click the screenshot file, and select the TortoiseSVN->Properties menu. There you will find the svn:mime-type property, probably incorrectly set to “application/octet-stream”. Change that to the proper mime type of “image/png” or “image/jpg” accordingly. Afterwards, commit the change.

    If you prefer command line SVN:

    svn propset svn:mime-type image/png screenshot-1.png
    svn commit
    

    Or similar. If somebody uses a different SVN client, look for “properties” and then the svn:mime-type property.

    Once you do that, upload the changes and go make coffee. The information will sync out, but it may take a little while.

    Clarification on Taking Over Plugins 

    Sometimes people get random emails from strangers about taking over their old plugins, and I wanted to take a moment to explain how that works.

    First of all, the plugin team does not hand out your email. If you’ve been contacted by someone, they got your email or contact information off your website or plugin code.

    When someone comes to us asking about taking over a plugin, we ask if they’ve attempted to contact the original dev first. If they have and gotten no reply (or if they can’t find a way to contact you), we’ll email you about it and give you their email so you can contact them back. It is possible that someone may just email you out of the blue asking about taking over your plugin. However. Under absolutely no circumstances should you feel like you must give up your plugin, even if it’s old and out of date.

    Your plugin is yours. We will only close it if there are security issues or guideline violations, and we will always email you about that (so remember to keep your email up to date in your forum profile!). We also will never just give away your plugin without contacting you first, and getting your approval.

    If someone would rather close a plugin than hand it over, that’s their call and we support it. We would rather have the plugin carry on, of course, but hey, things happen. That’s why some names are ‘blocked’ from the repository, by the way. We’ve closed an older plugin.

    If you want to close your plugin email us at pluginsATwordpress.org and link us to the plugin page. But do consider giving it away too!

      Mika,

      Is there a list or wiki page where plugin authors can add their plugins to a list of those in need of new ownership?

      If not, would it be helpful to have one for people who don’t want to, or can’t, support their plugins anymore to offer them up to the community for new development and support blood before closing them down?

      • Ipstenu (Mika Epstein) 10:12 pm on February 6, 2014 Permalink | Log in to Reply

        No, and since the Wiki is editable by anyone, it wouldn’t be maintainable and verifiable easily. Generally I suggest people update their readme to say “This is no longer maintained.”

      • Alex Mills (Viper007Bond) 7:37 am on February 7, 2014 Permalink | Log in to Reply

        It’d be cool if there we could just flag our plugins in need of new management.

        EDIT: Mika’s suggestion of editing the readme to say so is probably better as it’s unlikely it’d be useful to have a list of plugins that need new ownership.

    • Ben Lobaugh (blobaugh) 10:12 pm on February 6, 2014 Permalink | Log in to Reply

      Thanks Mika! As someone who has been on both sides of this I have to say the plugin team does a great job!

      Eric- I do not think there is one on WordPress.org anywhere, but there are a couple 3rd party sites that have setup systems like that.

    • Chad Butler 10:20 pm on February 6, 2014 Permalink | Log in to Reply

      Thanks Mika! This is great clarification.

      I always assumed that the plugin team approached it the way you described, but it is good to have it said out loud.

    • Andrew Nacin 10:35 pm on February 6, 2014 Permalink | Log in to Reply

      I’d say that it’d be cool if we have a system for putting plugins up for adoption, but I think this would work fine: If a plugin author wanted to put a plugin up for adoption, I’d suggest they create a post in their plugin forum and make it “sticky”. They could also update their readme if they wanted to link to that post. Those interested could then comment.

    • Ajay 12:10 am on February 7, 2014 Permalink | Log in to Reply

      What about cases where the plugin developer has disappeared and is no longer contactable?

    • Stephen Cronin 2:49 am on February 7, 2014 Permalink | Log in to Reply

      Mika,

      What happens when you close a plugin? Does the plugin slug become reserved or can it be reassigned at a later date?

      If it can be re-assigned, then someone could release a plugin reusing a retired slug and anyone out there still using the original plugin would get an update notice (assuming sufficiently high version number). That could potentially be confusing / dangerous.

      I’ve always wondered about that..

      • Ipstenu (Mika Epstein) 4:06 am on February 7, 2014 Permalink | Log in to Reply

        The slug is reserved and remains so unless the owner wants to give it to someone else.

        Example of something that happened once. A plugin was closed for security issues. Dev said “meh, I’m done.” Another dev asked to take it over. Original Dev said “Sure!” We added the new Dev, but the code was required to be patched before we reopened the plugin. Everything worked out better than expected :)

      • Ajay 8:45 pm on February 8, 2014 Permalink | Log in to Reply

        I closed a few plugins since they really couldn’t be used again because the services they were integrating no longer existed. I can still see the URL with a big RED message saying it is closed.

    • Workshopshed 9:58 am on February 7, 2014 Permalink | Log in to Reply

      I had someone contact me regarding taking over a plugin I was no longer interested in maintaining as it needed significant changes to work with an API change.
      However all that seemed to happen was a banner advert was placed on it and no further changes were done.

        An … ad? Is not okay. I’ll take a look to see if it’s violating our guidelines. That said, I often ask that people show me what code they want to update BEFORE I give a plugin away. I gave away one that I just don’t care to work on anymore :)

    • FranceImage 2:04 pm on February 8, 2014 Permalink | Log in to Reply

      Hi,

      I think the repository would gain in adopting another paradigm like github.

      As it is, plugins are abandoned because the authors are demotivated; an easy way to accept code from contributors may help them keep their motivation.

      If an author neglects his project, code consumers could see if it has been forked; the forked project would gain momentum if it is more alive.

      My 2 cents

    • Todd Lahman 1:01 pm on February 11, 2014 Permalink | Log in to Reply

      This post from Mike Jolley completely sums up what needs to be done:

      http://mikejolley.com/2013/12/wordpress-org-wishlist/

      I would add to this, the developers need mod permission to delete comments that are off topic. My preference would be to fully integrate with Github, adopting their system entirely. WordPress.org is outdated, and the moderators system reminds me of the IRC back in the mid 1990s when Eggdrop bots ruled the chat rooms.

    TinyMCE 4.0 

    In case you missed the announcement over on Make/Core, we’re moving to TinyMCE 4.0

    I shall quote:

    This is a major upgrade for the WordPress editor. There are many changes in 4.0:

    • New UI and UI API.
    • New theme.
    • Revamped events system/API.
    • Better code quality, readability and build process.
    • Lots of (inline) documentation.
    • And generally many improvements everywhere.

    All default TinyMCE plugins have been upgraded. The WordPress implementation custom plugins  were upgraded too. Looking in the plugin repository, there are a lot of WordPress plugins  that add a TinyMCE plugin. Because of all the API changes, most of these plugins would need an update too. If you are the author of such plugin, please test it in trunk now.

    Generally there are three groups of TinyMCE plugins added by WordPress plugins:

    • Custom plugin created specifically for the WordPress plugin. If you’ve developed this kind of plugin, please see the 3.x to 4.0 migration guide and the 4.0 API documentation.
    • WordPress plugins that add third-party or default TinyMCE plugins would (of course) need to be updated to include the 4.0 version of the plugin. The PHP global $tinymce_version can be used to determine which plugin to load.
    • Mini-plugins that only add a button to the toolbar. This works pretty much the same. It is advisable to update to use the ‘dashicons’ icon font instead of image icon.

    TinyMCE 4.0 includes a ‘compat3x’ plugin that should prevent all fatal errors caused by old plugins and adds compatibility for most of the 3.x API methods. If there are any editor related Javascript errors while running trunk, please open a trac ticket quoting the first error from the browser console.

    So please read, test, and update your plugins as needed.

    Notice: SVN will reject PHP with errors 

    When you commit PHP files, the repository will no longer let you commit them if they have PHP syntax errors. Such an error would make the plugin fail when it tried to load the file anyway, so think of this as a ‘for your own protection’ kind of thing.

    So if you get a kick-back error like this:


    Error: Commit failed (details follow):
    Error: Commit blocked by pre-commit hook (exit code 1) with output:
    Error: PHP Parse error: syntax error, unexpected end of file in - on line 1234
    Error:
    Error: ***********************************
    Error: PHP error in: really-cool/tags/1.0/really-cool.php:
    Error: Errors parsing really-cool/tags/1.0/really-cool.php
    Error: ***********************************
    Error: This error was generated by a custom hook script on the Subversion server.
    Error: Please contact your server administrator for help with resolving this issue.
    Completed!:

    you need to fix the syntax errors in the file before uploading.

      That’s great! I’ve seen this happen occasionally, and its no fun for the developer or the plugin users.

    • Andrew Nacin 8:18 pm on December 22, 2013 Permalink | Log in to Reply

      Please note: This currently does a PHP 5.4 syntax check. Please be careful if you are using 5.3 or 5.4-specific language features, like namespaces, closures, short array or ternary syntaxes, etc. These will break sites running PHP 5.2 (which is a majority of sites).

      This has actually been enabled for many months.

      • Rafael Ehlers 10:36 am on December 23, 2013 Permalink | Log in to Reply

        Hi @nacin can you elaborate on “ternary syntaxes” that you’ve mentioned ?!

        • Samuel Wood (Otto) 2:47 pm on December 23, 2013 Permalink | Log in to Reply

          A ternary operator in PHP looks like this:

          ( expression1 ) ? expression2 : expression3

          If the expression1 evaluates to true, then the result is expression2. If not, then the result is expression3. A simple example:

          $variable = ( $a > $b ) ? ‘A is greater than B’ : ‘A is not greater than B’;

          Obviously the expressions can be more complex than this.

          Now, as of PHP 5.3, there is a shorthand ternary operation that works like this:

          ( expression1 ) ?: expression3

          This basically evaluates expression1, and if it’s equivalent to true, then the value of expression1 is returned. If not, then expression3 is returned. This is useful in either/or cases.

          Say you have a function returns a string or false. You want to replace the false case with some other string, like “fake”. This will do it:

          $var = ( getString() ) ?: ‘fake’;

          However, the ?: shorthand is PHP 5.3 only. In 5.2 it will cause a syntax error. You could do the same thing in 5.2 code without the shorthand:

          $var = ( getString() ) ? getString() : ‘fake’;

          Or if you needed to not call getString twice, by using a separate call:

          $var = getString();
          $var = ( $var ) ? $var : ‘fake’;

          If you’re using 5.3-only code of any sort, make sure that your plugin checks for 5.2 cases (still more than half of all installs) and fails gracefully. Or just write 5.2 compliant syntax. There’s nothing in 5.3 and up that’s actually required for most cases.

    How to fix the intentionally vulnerable plugin 

    If you have not reviewed the intentionally vulnerable plugin, then I suggest you do so before reading on.

    The intentionally vulnerable plugin demonstrates a range of security vulnerabilities that are commonly seen in WordPress plugins. In this post I aim to go through each vulnerability giving a little background on why it is dangerous and how it should be fixed.

    SQL injection

    This is a rather famous vulnerability that can be exploited by an attacker to modify database queries. This can allow the attacker to read sensitive information from the database, modify data stored in the database, and possibly even execute commands on database server, among other things. The basic idea is that if untrusted user input is included directly in a query then maliciously formatted input can be used to alter the query’s syntax.

    The first SQL injection vulnerability is caused by the incorrect usage of the wpdb::prepare() method on line 42:

    $wpdb->query( $wpdb->prepare( "INSERT INTO login_audit (login, pass, ip, time) VALUES ('$login', '$pass', '$ip', '$time')" ) );
    

    When using the prepare() method placeholders, such as %s and %d, should be used in the query string which is the first argument of the method — the method is not magic, it cannot parse the query to determine what was user input! The variables are then passed in as separate arguments so that they can be escaped properly before being included in the query. This rather common error has been made more obvious since the release of WordPress 3.5 which required more than one argument to be passed to the method.

    The correct usage, and the fix, is:

    $wpdb->query( $wpdb->prepare( "INSERT INTO login_audit (login, pass, ip, time) VALUES (%s, %s, %s, %s)", $login, $pass, $ip, $time ) );
    

    The other two SQL injection vulnerabilities, on lines 102 and 127, are caused by incorrectly escaping user input that is not used in a quoted context of an SQL query. The esc_sql() function can only be safely used to escape input that will be used within quotes. However, the two queries are using input as a numeric argument that is not enclosed within quotes:

    $log = $wpdb->get_row( "SELECT * FROM login_audit WHERE ID = " . esc_sql( $id ), ARRAY_A );
    // ... and ...
    $wpdb->query( "DELETE FROM login_audit WHERE ID = " . esc_sql( $_POST['id'] ) );
    

    To fix this you should use the prepare() method with a %d placeholder:

    $log = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM login_audit WHERE ID = %d", $id ), ARRAY_A );
    // ... and ...
    $wpdb->query( $wpdb->prepare( "DELETE FROM login_audit WHERE ID = %d", $_POST['id'] ) );
    

    It is also possible to sanitize numeric input by casting to int or using the absint() method.

    Cross-site scripting

    Cross-site scripting (XSS) is one of the most prevalent security vulnerabilities in web applications. XSS is also commonly found in WordPress plugins, so it features heavily in the intentionally vulnerable plugin. XSS is often classed as either “persistent” or “reflected”. An XSS vulnerability is persistent if the unsafe user input is stored in the database, and then output to other users in future requests. It is known as reflected if the unsafe user input is output immediately in response to a request containing the dangerous input. To exploit a reflected XSS vulnerability the attacker would have to convince a victim to click on their specially crafted link that triggers a malicious script. However, a persistent XSS vulnerability will allow the attacker to input their malicious script themselves and then wait for unsuspecting users to visit or click on benign looking links.

    There are two instances of persistent XSS in the intentionally vulnerable plugin, in dvp_view_all_logs() and dvp_view_log(). Both of these functions output data straight from the database without escaping it. All of this data originated from the user in dvp_log_failed_login(). For example, an attacker could purposefully fail a login attempt using a password of <script>alert(1)</script>. The fix for this would be to use an appropriate escaping function, such as esc_html() or esc_attr() when outputting data from the database. Data can also be sanitized when being stored in the database using KSES, or strip_tags() when no HTML is expected, in addition to escaping on output.

    There are also multiple examples of reflected XSS. On lines 104 and 115, the $id variable, which was originally $_GET['id'], is output without any escaping. Line 104 should be fixed with esc_html(), and line 115 should be fixed with esc_attr(). Another problem is the use of $_SERVER['PHP_SELF'] on line 116 to get the current URL. This is an extremely common problem that allows XSS since an attacker can control its value and include malicious HTML that will break out of the attribute and execute a script. This should be fixed by using a WordPress function, such as menu_page_url(), to get the correct URL.

    Cross-site request forgery

    Another extremely common vulnerability in web applications is the failure to prevent cross-site request forgeries (CSRF). This type of attack exploits a request handler that checks authorisation, but not intention. A malicious website is able to send a request to another site that the user is authenticated to. The vulnerable target site will accept this request since it is sent with valid authentication cookies. However, the user did not intend for the action to be performed. WordPress plugins can defend against this type of attack by using nonces. These are action dependent random strings that cannot be predicted by an attacker, but can be verified by WordPress. So, if a request does not include a valid nonce then it is rejected.

    The intentionally vulnerable plugin looks as if it makes use of nonces to defend against CSRF, but the author has made a couple of mistakes that leave it exploitable. Firstly, the use of nonce generation and verification functions without passing the $action parameter is insecure. Lines 114 and 123 should be edited to add the use of an action. Note that this mistake would be caught when developing with WP_DEBUG enabled as this use of check_admin_referer() raises a notice.

    The second mistake is more subtle. On line 137 the following check is made:

    if (isset($_REQUEST['nonce']) && ! wp_verify_nonce($_REQUEST['nonce'], 'dvp_settings'))
        // ... failed nonce check
    

    The problem with this check is that it requires the nonce request parameter to be set to ever evaluate to true. This means that an attacker can simply omit this parameter to bypass the nonce verification. This type of logic error means that it is highly recommended that you use check_admin_referer() instead of wp_verify_nonce() directly.

    Missing capabilities checks

    The lack of capabilities checks in the log deletion handler allows for a privilege escalation attack. Any logged in user is able to delete rows from the login_audit table since there are no privilege checks. Note that unauthenticated users cannot exploit this because the handler is not hooked into a _nopriv admin-post.php action. However, this is still a serious security failure. So, always remember to use the appropriate current_user_can() capabilities checks on your admin pages and privileged request handlers.

    Failure to exit after a redirect

    When a script redirects the user to another page execution will actually continue on the server side until it exits. This means that it is almost always desirable to make a call to exit or die() when making a redirect. The failure to do this on line 140 means that the capabilities check and CSRF defence (even if it didn’t have a logic error) are rendered useless as a forged request or request made by a low privilege user will actually cause the settings to be updated even though the conditional triggered a redirect. (Note that using check_admin_referer() would have also nullified the problem for a forged request since it calls die() on failure.) The other locations where redirects are used are not vulnerable in the same way because they are called at the end of script execution, but it would be good practice to add exits there as well.

    This vulnerability is exacerbated by the fact that the plugin has a ridiculous update loop that would allow a successful attacker to update any option in the database. Instead a plugin should know which options it is in charge of and only modify those whitelisted options.

    Open redirect

    On a redirect related note, there is an open redirect vulnerability in the deletion handler on line 130. In this plugin the intention is to return the user to the list of failed login attempts, so wp_safe_redirect() should have been used instead of plain old wp_redirect(). However, in this situation it would be even better to redirect to a hardcoded URL using menu_page_url() or admin_url() and then remove the ability to specify the redirect through the request parameters.

    IP forgery

    The dvp_get_ip() function can be tricked into logging an incorrect IP address since the X-Forwarded-For header is user controllable. This is bad news for a variety of reasons. For security logging purposes it degrades the utility of the audit trail as an attacker pretends to be coming from a legitimate address. If it were used for securing access then it is trivially by-passable. In the case of this plugin this can also lead to SQL injection and persistent XSS.

    Conclusion

    There are many things that plugin authors can do wrong! The number one rule to remember is that the user is not to be trusted. Always validate and escape anything that could be controlled by a user.

    I hope that participants found this to be a useful exercise and that this review post has helped your understanding of plugin security.

    The Order of Things 

    Since WP 3.6.1, you may get odd errors like “Call to undefined function wp_validate_redirect()” errors in WP Admin where AJAX is used. The error is due to plugins that call wp_get_referer() on init.

    While this will be patched more in 3.6.2, today’s quick lesson in ‘Making your plugins better’ is this simple note:

    Doing anything before plugins_loaded or init is a bad idea.

    If you find an affected plugin, please feel free to report it here: http://core.trac.wordpress.org/ticket/25294

      In general @nacin‘s advice that the only thing a plugin should be doing on inclusion is add_action() and add_filter() is extremely good advice, but I’m concerned it might be taken too literally.

      There are other things that can and should be done when loading files and I’d hate for people who review code for best practices for corporations but who are not really experienced with WordPress to add that literally to the list of required best practices without including some caveats.

      Here are some caveats I would add to @nacin‘s advice as being okay to do on plugin inclusion:

      • Capturing __FILE__ or __DIR__ into a static variable of a class for later use.
      • Calling spl_autoload_register().
      • Pre-parsing of environment variables such as $_SERVER['REQUEST_URI'] into static variables of classes.
      • Defining architectural relationships between classes in a plugin that are beyond what PHP provides at the language level, i.e. defining one class as a mixin to another and storing that information in static variables of a class.
      • Possibly other things that are pure PHP/environment and/or that do not have an dependencies on the functions or classes in WordPress, depending on use-case, of course.

      > The error is due to plugins that call wp_get_referer() on init.

      You probably meant on load rather than init?

      Maybe more precise: Calling any WordPress functions, except add_action() and add_filter(), on plugin inclusion is a bad idea.

        Knut, just to clarify my ignorance, what do you guys refer as “plugin inclusion”? I suppose it’s an activated plugin start up…. Normally, if it’s the case, I call

        
        if( is_admin() )
            add_action( 'plugins_loaded', 'start_everything' );
        

        I also suppose is_admin() is not a bad idea, is it?

    Secure SWFUpload 

    Do you use SWFUpload? Have you been getting a lot of emails from us telling you it’s not secure? We have a solution. Or rather, WordPress has one.

    FORK IT

    The WordPress security team has officially forked the long-abandoned SWFUpload project and is strongly encouraging all web developers who use SWFUpload to update.

    We strongly suggest you do not use SWFUpload. But if you must, use this fork.

    Font Awesome is permitted in the Plugin Repository 

    This took longer than we would have liked to say, but there were communication issues on multiple fronts.

    You can use the Font Awesome font files and CSS in your code, per the current Font Awesome License:

    As far as crediting is concerned, we feel attribution is always good. You should always put that in your source code, but your readme is optional. Credit links must be opt-in if they show on the front facing part of your site (this includes the login page), but that’s nothing new.

    So with that said, we’re going through the plugins that had been closed for Font Awesome usage and opening them. If we missed yours, please email us at plugins at wordpress.org, with a link to the plugin (like http://wordpress.org/extend/plugins/font-awesome/ which is open) and we’ll check right away.

    Plugins SVN Repository DNS Change Today 

    In a short while (next 30 minutes or so), plugins.svn.wordpress.org will undergo a DNS change as part of a datacenter migration. The TTLs are low, so this should only take a few minutes.

    Nothing will go down, but the SVN repository will become temporarily read-only. If you try to commit code during this time, you’ll receive an maintenance message pointing you here. Plugin pages and downloads will not be affected.

    Also, the associated Trac at plugins.trac.wordpress.org will be taken offline (for up to an hour) while it is migrated and re-synced.

      ok good luck andrew ^-^

    • Andrew Nacin 8:17 pm on April 23, 2013 Permalink

      Plugins SVN is online again. If your commits are not working, flush your DNS cache. Here’s the proper IP address for plugins.svn.wordpress.org:

      $ dig plugins.svn.wordpress.org +short
      66.155.40.242
      

      Trac remains down while it re-syncs.

    • Andrew Nacin 8:37 pm on April 23, 2013 Permalink

      Everything is back online.

      If you don’t know how to flush your DNS on Windows, open up cmd and type:
      ipconfig /flushdns

    • jquindlen 11:55 pm on April 23, 2013 Permalink

      To flush your DNS on Windows, open a command prompt (run > cmd) and type: ipconfig /flushdns

      Hey could someone maybe help me out…I’m a long time WP Developer, but just release our first public Plugin that has been accepted and approved for the WP directory and the SVN.

      I received the email to wait about an hour (it’s been many) and login with this account information.

      But I think I may have screwed up, as I think I have a previous registration on the SVN Repository using this same username. When I log in to the already created account, it says I am not involved in any projects, but the link to the SVN Repository shows my files…

      So what do ya think…should I just be a little more patient?

      Thanks…

      Johnny

      p.s. Sorry if this isn’t a good place to ask this question. But I’m a quick learner.

      • Ipstenu (Mika Epstein) 6:41 pm on May 23, 2013 Permalink

        Email plugins AT wordpress.org if you need help with this. Also re-read the email we sent, especially the part where it says to use the WordPress.org login ID and password to get into SVN. ;)

      My second plugin got approved by WordPress, and I also got SVN repository URL. I checkout out the plugin with Tortoise SVN, copied my plugin files to trunk folder, but when I am trying to commit it, I am getting the following error.

      Commit failed (details follow):
      At least one property change failed; repository is unchanged
      Server sent unexpected return value (400 Bad Request) in response to PROPPATCH
      request for ‘/!svn/txn/747084-g5of’

      am I doing it right? How to solve this issue?

      Here is the my question in support forum http://wordpress.org/support/topic/commit-failed-while-uploading-my-plugin-to-repository?replies=1
