• PHP Page Stopped outputting content After Running "yum install php-devel" Command

  - by stwhite

  This error is bizarre but after running the "yum install php-devel" command (after a long day of trying to install Facedetect and OpenCV for face detection) my site stopped functioning. The site uses mysql and php. When you hit the url, the page executes the mysql and the php, but it appears to randomly stop outputting the content of the page. None of the code was changed and the site was working flawlessly prior to running the mentioned ssh command. I do use output buffering in the site, but after removing the calls "ob_flush", "ob_end_flush" and "ob_start" it didn't appear to help—still having issues with the site. Any ideas what this could be? Here is output from terminal: [myserver ~]# cd Facedetect-4b1dfe1 [myserver Facedetect-4b1dfe1]# phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 [myserver Facedetect-4b1dfe1]# configure bash: configure: command not found [myserver Facedetect-4b1dfe1]# phpize && configure && make && make install Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 bash: configure: command not found bash: Read: command not found [myserver Facedetect-4b1dfe1]# make make: *** No targets specified and no makefile found.

• Serving static content with Apache web server and Tomcat

  - by Hunter

  I've configured Apache web server and Tomcat like this: I created a new file in apache2/sites-available, named it "myDomain" with this content: <VirtualHost *:80> ServerAdmin [email protected] ServerName myDomain.com ServerAlias www.myDomain.com ProxyPass / ajp://localhost:8009 <Proxy *> AllowOverride AuthConfig Order allow,deny Allow from all Options -Indexes </Proxy> </VirtualHost> Enabled mod_proxy and myDomain a2enmod proxy_ajp a2ensite myDomain Edited Tomcat's server.xml (inside the Engine tag) <Host name="myDomain.com" appBase="webapps/myApp"> <Context path="" docBase="."/> </Host> <Host name="www.myDomain.com" appBase="webapps/myApp"> <Context path="" docBase="."/> </Host> This works great. But I don't like to put static files (html, images, videos etc.) into {tomcat home}/webapps/myApp's subfolders instead I'd like to put them the apache webserver's root WWW directory's subdirectories. And I'd like Apache web server to serve these files alone. How could I do this? So all incoming request will be forwarded to Tomcat except those that ask for a static file.

• zsh : How to list directory content with tab?

  - by Philippe CM

  I just switched from BASH to ZSH and thing are pretty good, but: when I start typing cd /usr/share/s and hit TAB, this is what I get : $ cd /usr/share/sane/ sane/ skype/ ssl-cert/ screen/ smplayer/ strigi/ seed-gtk3/ snmp/ synaptic/ sgml/ software-properties/ system-config-printer/ sgml-base/ soprano/ sysv-rc/ sgml-data/ sounds/ simple-scan/ splashy/ And this is ok. If I then hit TAB again, I get $ cd /usr/share/screen/, the next candidate, witch is also OK. (BTW, how do I cycle back to the previous candidate? Sorry, on to my question) Now what if I want to see the contents of /usr/share/screen/ now ? You now, BASH-style? The cursor is at the end of the line, will I have to ctrl-a (or home), then del del (to erase cd) then ls then ENTER? That seems like a lot of typing. (And it - possibly unnecessarily - enters the command in the history) Would not there be a key (maybe modifier-TAB? but the obvious candidates are already taken by the desktop... I digress) that would tell zsh to stop cycling through /usr/share/ and instead, just list the content /usr/share/screen/ ?

• Calling Msbuild from Php - Wrong Codepage and Culture

  - by miasbeck

  I have a Php script that calls Msbuild via System: <?php system( "msbuild umlaut.proj" ); ?> This is the project file: <?xml version="1.0" encoding="UTF-8"?> <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="EchoUmlaut" ToolsVersion="3.5"> <Target Name="EchoUmlaut"> <Message Text="Umlaute: Ä Ö Ü ä ö ü ß" /> </Target> </Project> When I call Msbuild directly from the command line the output of msbuild is in German (as excpected) and the umlauts come out OK (I chcp to 1252). But when I use php to call msbuild the umlauts are wrong, and the output of msbuild is changed to English. I wonder what I can do to prevent this. C:\>chcp Aktive Codepage: 1252.

• jQuery: AJAX umlauts & special characters are a mess

  - by rayne

  I've just created my first ajax function with jQuery which actually works, but unfortunately the character encoding (for characters like ä, ö, ü, ß, c, c, å, ø) is a nightmare. My files and my database are all UTF-8. I've tried a multitude of options in the ajax function and the PHP function, none of which were satisfactory. This is my ajax var dataString = { 'name': name, 'mail': mail // other stuff } $.ajax({ type: "POST", url: "/post.php", data: dataString, contentType: "application/x-www-form-urlencoded;charset=UTF-8", cache: false, success: function(html){ // do stuff } I've tried it without contentType: "application/x-www-form-urlencoded;charset=UTF-8" and I've tried to wrap the affected data in encodeURIComponent(), none of which worked. When I use that AJAX with htmlentities() in my php, my umlauts look like this in plain text: UE Ã?, AE Ã?, OE Ã?, ue ü, ae ä, oe o And like this in the database: UE Ãœ , AE Ä, OE Ö, ue ü, ae ä, oe o If I don't use htmlentities() but mysql_real_escape_string() instead (or neither), they look good in plain text, but they look like this in the database: AE Ä, OE Ö, UE Ãœ, ae ä oe ö ue ü I've been trying tons of options for hours now, but I can't find a solution that works. So far the only option I seem to have is having them look like a total mess in the database, but that would be very contraproductive if those data sets need to be edited.

• HTML inside webView

  - by Samuh

  I am posting some data to a server using DefaultHttpClient class and in the response stream I am getting a HTML file. I save the stream as a string and pass it onto another activity which contains a WebView to render this HTML on the screen: response = httpClient.execute(get); InputStream is = response.getEntity().getContent(); BufferedReader br = new BufferedReader(new InputStreamReader(is,"utf-8")); StringBuffer sb = new StringBuffer(); String line; while((line=br.readLine())!=null){ sb.append(line); sb.append("\n"); } is.close(); Intent intent = new Intent(this,Trial.class); intent.putExtra("trial",sb.toString()); startActivity(intent); Log.i("SB",sb.toString()); In Second Activity, the code to load the WebView reads: WebView browser = ((WebView)findViewById(R.id.trial_web)); browser.getSettings().setJavaScriptEnabled(true); browser.loadData(html,"text/html", "utf-8"); When I run this code, the WebView is not able to render the HTML content properly. It actually shows the HTML string in URL encoded format on the screen. Interestingly, If I copy the Loggers output to HTML file and then load this HTML in my WebView(using webview.loadurl(file:///assets/xyz.html)) everything works fine. I suspect some problem with character encoding. What is going wrong here? Please help. Thanks.

• How to deal with special characters in ASP.NET's HyperLink.NavigateUrl?

  - by DJ Pirtu

  I am currently having troubles figuring out how to handle a filepath to be (dynamicly) passed out to a HyperLink control's NavigateUrl property. Let's say that I'm trying to refer to a file named jäynä.txt at the root of C:. Passing "file:///C:/jäynä.txt" result to a link to file:///C:/jäynä.txt, as does HttpUtility.UrlPathEncode("file:///C:/jäynä.txt"). Replacing the äs with %E4, which gives the string "file:///C:/j%E4yn%E4.txt", does give a working link to file:///C:/jäynä.txt, but I have not been able to find a way to make the replacement without defining it myself. With Replace("ä", "%E4"), for example. Is there a way to automaticly handle the filepath string so that the HyperLink would display it correctly, without manualy listing what characters to replace in the string? Additional Note: There may be a way to work around this by spesifying the character encoding in which the page is rendered, because debugging shows that the HyperLink at least saves the string "file:///C:/jäynä.txt" unchanged, but somehow mangles it around the time of rendering. However, this seems only be the case in rendering of the NavigateUrl because other components as well as HyperLink's Text-property are all quite capable of rendering the character ä unchanged.

• Chunked responses in libevent2

  - by Sri

  Hi I am trying to do a chunked response (of large files) in libevent this way:: evhttp_send_reply_start(request, HTTP_OK, "OK"); int fd = open("filename", O_RDONLY); size_t fileSize = <get_file_size>; struct evbuffer *databuff = NULL; for (off_t offset = 0;offset < fileSize;) { databuff = evbuffer_new(); size_t bytesLeft = fileSize - offset; size_t bytesToRead = bytesLeft > MAX_READ_SIZE ? MAX_READ_SIZE : bytesLeft; evbuffer_add_file(databuff, fd, offset, bytesToRead); offset += bytesToRead; evhttp_send_reply_chunk(request, databuff); // send it evbuffer_free(databuff); // destroy it } evhttp_send_reply_end(request); fclose(fptr); Problem is with this I have a feeling the add_file is asynchronous so the 3rd or so evhttp_send_reply_chunk gives me an error (or something similar): [warn] evhttp_send_chain Closed(45): Bad file descriptor I set MAX_READ_SIZE to be 8 to actually test out chunked transfer encoding. I noticed there was a evhttp_request_set_chunked_cb (struct evhttp_request *, void(*cb)(struct evhttp_request *, void *)) method I could use but could not find any examples on how to use. For instance, how could I pass an argument to the callback? The argument seems to be the same argument that was passed to the request handler which is not what I want, because I want to create an object that holds the file descriptor and the file offset I am sending out. Appreciate all help. Thanks in advance Sri

• FTP server output and accents

  - by James P.

  I've written this little test class to connect up to an FTP server. import java.io.BufferedInputStream; import java.io.IOException; import java.io.InputStream; import java.net.MalformedURLException; import java.net.URL; import java.net.URLConnection; public class FTPTest { public static void main(String[] args) { URL url = null; try { url = new URL("ftp://anonymous:[email protected]"); } catch (MalformedURLException e) { e.printStackTrace(); } URLConnection conn = null; try { conn = url.openConnection(); } catch (IOException e) { e.printStackTrace(); } InputStream in = null; try { in = conn.getInputStream(); } catch (IOException e) { e.printStackTrace(); } BufferedInputStream bin = new BufferedInputStream(in); int b; try { while ((b = bin.read()) != -1) { char c = (char) b; System.out.print("" + (char) b); } } catch (IOException e) { e.printStackTrace(); } } } Here's the output: -rw-r--r-- 1 ftp ftp 4700 Apr 30 2007 premier.java -rw-r--r-- 1 ftp ftp 88576 Oct 23 2007 Serie1_1.doc -rw-r--r-- 1 ftp ftp 1401 Nov 21 2006 tp20061121.txt drwxr-xr-x 1 ftp ftp 0 Apr 23 20:04 répertoire Notice the name of the directory at the end of the list. There should be an "é" (e with acute accent) instead of the double character "é". This reminds me of an issue encountered previously with JSF where there was a mix-up between standards. I have little experience with character-encoding though so I'm not sure what's happening. I'm supposing that the server output is in ASCII so how do I adapt the output so it appears correctly in the console?

• feedparser fails during script run, but can't reproduce in interactive python console

  - by Rhubarb

  It's failing with this when I run eclipse or when I run my script in iPython: 'ascii' codec can't decode byte 0xe2 in position 32: ordinal not in range(128) I don't know why, but when I simply execute the feedparse.parse(url) statement using the same url, there is no error thrown. This is stumping me big time.

• Unicode strings in my C# App are shown with question marks

  - by mrbamboo

  Hi, I have a header file in C++/CLR project, which contains some strings in different languages. arabic, english, german, chinese, french, japanese etc... I have a second project written in C#. Here I access the strings stored in the header file of the C++/CLR project. The encoding of the header file is Unicode - Codepage 1200 or UTF-8. the visual studio editor is able to display the strings correctly. At runtime I access these strings and assign them into a local String variable. Here I recognized that many strings are not shown correctly. Doesn't matter if I assign them or not. Accessing the original place (while debugging) shows me all the foreign strings with question marks. Especially chinese, just question marks. Example : "So?e St?ange ?ext in Ch?n?se" (This is not the best example, I know) What is the problem? I read that C# is by default UTF-16, My header file containing the strings is UTF-16 or UTF-8. I must be able to handle strings in different languages. What am I doing wrong?

• Writing XML in different character encodings with Java

  - by Roman Myers

  I am attempting to write an XML library file that can be read again into my program. The file writer code is as follows: XMLBuilder builder = new XMLBuilder(); Document doc = builder.build(bookList); DOMImplementation impl = doc.getImplementation(); DOMImplementationLS implLS = (DOMImplementationLS) impl.getFeature("LS", "3.0"); LSSerializer ser = implLS.createLSSerializer(); String out = ser.writeToString(doc); //System.out.println(out); try{ FileWriter fstream = new FileWriter(location); BufferedWriter outwrite = new BufferedWriter(fstream); outwrite.write(out); outwrite.close(); }catch (Exception e){ } The above code does write an xml document. However, in the XML header, it is an attribute that the file is encoded in UTF-16. when i read in the file, i get the error: "content not allowed in prolog" this error does not occur when the encoding attribute is manually changed to UTF-8. I am trying to get the above code to write an XML document encoded in UTF-8, or successfully parse a UTF-16 file. the code for parsing in is DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder loader = factory.newDocumentBuilder(); Document document = loader.parse(filename); the last line returns the error.

• Can't get data with spaces into the database from Ajax POST request

  - by J Jones

  I have a real simple form with a textbox and a button, and my goal is to have an asynchronous request (jQuery: $.ajax) send the text to the server (PHP/mysql a la Joomla) so that it can be added to a database table. Here's the javascript that is sending the data from the client: var value= $('#myvalue').val(); $.ajax( { type: "POST", url: "/administrator/index.php", data: { option: "com_mycomponent", task: "enterValue", thevalue: value, format: "raw"}, dataType: "text", success: reportSavedValue } ); The problem arises when the user enters text with a space in it. The $_POST variable that I receive has all the spaces stripped out, so that if the user enters "This string has spaces", the server gets the value "Thisstringhasspaces". I have been googling around, and have found lots of references that I need to use encodeURIComponent. So I have tried it, but now the value that I get from $_POST is "This20string20has20spaces". So it appears to be encoding it the way I would expect, only to have the percent signs stripped instead of the spaces, and leaving the hex numbers. I'm really confused. It seems that this sort of question is asked and answered everywhere on the web, and everywhere encodeURIComponent is hailed as the silver bullet. But apparently I'm fighting a different breed of lycanthrope. Does anyone have any suggestions?

• SHGetFolderPath returns path with question marks in it

  - by Colen

  Hi, Our application calls ShGetFolderPath when it runs, to get the My Documents folder. This normally works great. However, for three users - ???????, Jörg and Jörgen (see if you can spot the pattern!) - the call returns some very strange results. For example, for ???????, the call returns: c:\Users\???????\Documents I assume there's some sort of character encoding shenanigan going on here, possibly related to Unicode, but I don't have any experience with that sort of thing. How can I get a useful path to the folder (and other related folders) out of windows, without grovelling through registry keys for the information? In an email to me, ??????? ("Dmitry"), told me his "my documents" folder was actually located here: C:\Users\43D6~1\Documents So I know there's a way to get a "normal" version of the path out of Windows, I just don't know what it is. Background: Our application is not unicode-aware, and uses standard "char *" strings. How can we get the "normal" path? I'm not opposed to calling the "unicode" version of the function, then converting it to "normal" text, if that's possible. Converting the application entirely to use unicode is not an option here (we don't have the time). Thanks.

• Opening a Unicode file with Perl

  - by Jaco Pretorius

  I'm using osql to run several sql scripts against a database and then I need to look at the results file to check if any errors occurred. The problem is that perl doesn't seem to like the fact that the results files are unicode. I wrote a little test script to test it and the output comes out all warbled. $file = shift; open OUTPUT, $file or die "Can't open $file: $!\n"; while (<OUTPUT>) { print $_; if (/Invalid|invalid|Cannot|cannot/) { push(@invalids, $file); print "invalid file - $inputfile - schedule for retry\n"; last; } } Any ideas? I've tried decoding using decode_utf8 but it makes no difference. I've also tried to set the encoding when opening the file. I think the problem might be that osql puts the result file in UTF-16 format, but I'm not sure. When I open the file in textpad it just tells me 'Unicode'. Edit: Using perl v5.8.8

• Strange javascript decoding behavior in IE

  - by Yoni

  I run the following html snippet in IE8 and IE7 with non-English characters (we tried both Hebrew and Chinese), and the second link never works properly. The displayed text in the alert box is mangled. This occurs in IE8 and IE7, but not in firefox. It is not dependent on Windows's regional settings. Here is the html snippet (html header and footer omitted for brevity, the content-type is "text/html; charset=utf-8", and so is the response header): <p> <a href="javascript:alert('ab????ab')">link with English and Hebrew text</a> <a href="javascript:alert('ab%D7%A9%D7%9C%D7%95%D7%9Dab')">same text, url encoded</a> </p> Here is the alert box that pops up when clicking the second link: I know that the string for "????" is encoded as 8 bytes in utf-8, thus there are 8 %NN items, and there are also 8 weird characters in the alert box. The problem is, how can I make IE recognize that this is utf-8 encoding text, like firefox does?

• Servlet receiving data both in ISO-8859-1 and UTF-8. How to URL-decode?

  - by AJPerez

  I've a web application (well, in fact is just a servlet) which receives data from 3 different sources: Source A is a HTML document written in UTF-8, and sends the data via <form method="get">. Source B is written in ISO-8859-1, and sends the data via <form method="get">, too. Source C is written in ISO-8859-1, and sends the data via <a href="http://my-servlet-url?param=value&param2=value2&etc">. The servlet receives the request params and URL-decodes them using UTF-8. As you can expect, A works without problems, while B and C fail (you can't URL-decode in UTF-8 something that's encoded in ISO-8859-1...). I can make slight modifications to B and C, but I am not allowed to change them from ISO-8859-1 to UTF-8, which would solve all the problems. In B, I've been able to solve the problem by adding accept-charset="UTF-8" to the <form>. So the <form> sends the data in UTF-8 even with the page being ISO. What can I do to fix C? Alternatively, is there any way to determine the charset on the servlet, so I can call URL-decode with the right encoding in each case?

• Why might my PHP log file not entirely be text?

  - by Fletcher Moore

  I'm trying to debug a plugin-bloated Wordpress installation; so I've added a very simple homebrew logger that records all the callbacks, which are basically listed in a single, ultimately 250+ row multidimensional array in Wordpress (I can't use print_r() because I need to catch them right before they are called). My logger line is $logger->log("\t" . $callback . "\n"); The logger produces a dandy text file in normal situations, but at two points during this particular task it is adding something which causes my log file to no longer be encoded properly. Gedit (I'm on Ubuntu) won't open the file, claiming to not understand the encoding. In vim, the culprit corrupt callback (which I could not find in the debugger, looking at the array) is about in the middle and printed as ^@lambda_546 and at the end of file there's this cute guy ^M. The ^M and ^@ are blue in my vim, which has no color theme set for .txt files. I don't know what it means. I tried adding an is_string($callback) condition, but I get the same results. Any ideas?

• how to get selected chracter position in JTextArea?

  - by Reddy

  Hi! Here is a challenging question! Let me first tell you my scenario how am i implementing a solution to a problem. I am reading a log file and displaying it on the JTextArea. Log file is cp037 character coded. I was reading each file as a byte stream or byte array from the log file & displaying it. Anyways, i managed to display the text properly in JTextArea by cp037 character coding. Now, User may select a set of characters in the JTextArea. All i want is the position of first character of the user's selected text, from a nearest special character '+'(its character code in cp037 is 4E), which is prior to the selected text. This character may occur at several places in the JTextArea. In simple sentence, i want the first character location(of user selected text) from nearset '+' which should be occuring prior to the user's selected text. PS: cp037 is a type of character encoding scheme which is created by IBM & used for IBM Mainframes. Please fell free to ask me if the question is not clear...:-

• Strange problem on some client's browsers

  - by Gustavo Cardoso

  We are fighting a strange problem on the company that I work. We created a site of a promotion to a client where its consumers can register products barcodes to win prizes. The site was created using PHP and MySQL. The site uses SSL on every form. However, some consumers report to the client's call-center they was no able make a registration at the site. We try everything, but we cannot, by no ways, reproduce the problem. The consumers reported the problem on several browsers ranging from IE8 to Firefox, the problem is same on everyone them. One co-woker this weekend was able to catch this same bug on his wife's notebook and brought her computer to the company so we could test. However, here on the company the problem didn't happened and we can make the registration normally. We suppose this problem could be a matter of encoding and special characteres like ã and ç. But we are sure that all source files are UTF8- with BOM. We also suspect of MSXml version, but we are note sure anymore. Because of legal impediments the client cannot ask the consumers to install anything on they computers to test or fix the problem. Sorry but by complience rules we also cannot share the url of the site, what is a pity. I know it is too much on vacuun, but perhaps you could had crossed something similar. Thank you

• Why do browsers encode special characters differently with ajax requests?

  - by Andrei Oniga

  I have a web application that reads the values of a few input fields (alphanumeric) and constructs a very simple xml that is passes to the server, using jQuery's $.ajax() method. The template for that xml is: <request> <session>[some-string]</session> <space>[some-string]</space> <plot>[some-string]</plot> ... </request> Sending such requests to the server when the inputs contain Finnish diacritical characters (such as ä or ö) raises a problem in terms of character encoding with different browsers. For instance, if I add the word Käyttötarkoitus" in one of the inputs, here's how Chrome and Firefox send EXACTLY the same request to the server: Chrome: <request> <session>{string-hidden}</session> <space>2080874</space> <plot>Käyttötarkoitus</plot> ... </request> FF 12.0: <request> <session>{string-hidden}</session> <space>2080874</space> <plot>Käyttötarkoitus</plot> ... </request> And here is the code fragment that I use to send the requests: $.ajax({ type: "POST", url: url, dataType: 'xml;charset=UTF-8', data: xml, success: function(xml) { // }, error: function(jqXHR, textStatus, errorThrown) { // } }); Why do I get different encodings and how do I get rid of this difference? I need to fix this problem because it's causing other on the server-side.

• '£' character does not seem to encode properly - expect '%a3' but get '%u00a3'

  - by user243143

  Hello, I want to send The pound sign character i.e. '£' encoded as ISO-8859-1 across the wire. I perform this by doing the following: var _encoding = Encoding.GetEncoding("iso-8859-1"); var _requestContent = _encoding.GetBytes(requestContent); var _request = (HttpWebRequest)WebRequest.Create(target); _request.Headers[HttpRequestHeader.ContentEncoding] = _encoding.WebName; _request.Method = "POST"; _request.ContentType = "application/x-www-form-urlencoded; charset=iso-8859-1"; _request.ContentLength = _requestContent.Length; _requestStream = _request.GetRequestStream(); _requestStream.Write(_requestContent, 0, _requestContent.Length); _requestStream.Flush(); _requestStream.Close(); When I put a breakpoint at the target, I expect to receive the following: '%a3', however I receive '%u00a3' instead. We have tested many odd characters, but '£' seems to be the only character where theres a problem. Does anyone know what the problem is here? - Help would be greatly appreciated... Billy
