  • Good PHP / MYSQL hashing solution for large number of text values

    - by Dave
    Short descriptio: Need hashing algorithm solution in php for large number of text values. Long description. PRODUCT_OWNER_TABLE serial_number (auto_inc), product_name, owner_id OWNER_TABLE owner_id (auto_inc), owener_name I need to maintain a database of 200000 unique products and their owners (AND all subsequent changes to ownership). Each product has one owner, but an owner may have MANY different products. Owner names are "Adam Smith", "John Reeves", etc, just text values (quite likely to be unicode as well). I want to optimize the database design, so what i was thinking was, every week when i run this script, it fetchs the owner of a proudct, then checks against a table i suppose similar to PRODUCT_OWNER_TABLE, fetching the owner_id. It then looks up owner_id in OWNER_TABLE. If it matches, then its the same, so it moves on. The problem is when its different... To optimize the database, i think i should be checking against the other "owner_name" entries in OWNER_TABLE to see if that value exists there. If it does, then i should use that owner_id. If it doesnt, then i should add another entry. Note that there is nothing special about the "name". as long as i maintain the correct linkagaes AND make the OWNER_TABLE "read-only, append-new" type table - I should be able create a historical archive of ownership. I need to do this check for 200000 entries, with i dont know how many unique owner names (~50000?). I think i need a hashing solution - the OWNER_TABLE wont be sorted, so search algos wont be optimal. programming language is PHP. database is MYSQL.

  • How to restrict a content of string to less than 4MB and save that string in DB using C#

    - by Pranay B
    I'm working on a project where I need to get the Text data from pdf files and dump the whole text in a DB column. With the help of iTextsharp, I got the data and referred it String. But now I need to check whether the string exceeds the 4MB limit or not and if it is exceeding then accept the string data which is less than 4MB in size. This is my code: internal string ReadPdfFiles() { // variable to store file path string filePath = null; // open dialog box to select file OpenFileDialog file = new OpenFileDialog(); // dilog box title name file.Title = "Select Pdf File"; //files to be accepted by the user. file.Filter = "Pdf file (*.pdf)|*.pdf|All files (*.*)|*.*"; // set initial directory of computer system file.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop); // set restore directory file.RestoreDirectory = true; // execute if block when dialog result box click ok button if (file.ShowDialog() == DialogResult.OK) { // store selected file path filePath = file.FileName.ToString(); } //file path /// use a string array and pass all the pdf for searching //String filePath = @"D:\Pranay\Documentation\Working on SSAS.pdf"; try { //creating an instance of PdfReader class using (PdfReader reader = new PdfReader(filePath)) { //creating an instance of StringBuilder class StringBuilder text = new StringBuilder(); //use loop to specify how many pages to read. //I started from 5th page as Piyush told for (int i = 5; i <= reader.NumberOfPages; i++) { //Read the pdf text.Append(PdfTextExtractor.GetTextFromPage(reader, i)); }//end of for(i) int k = 4096000; //Test whether the string exceeds the 4MB if (text.Length < k) { //return the string text1 = text.ToString(); } //end of if } //end of using } //end try catch (Exception ex) { MessageBox.Show(ex.Message, "Please Do select a pdf file!!", MessageBoxButtons.OK, MessageBoxIcon.Warning); } //end of catch return text1; } //end of ReadPdfFiles() method Do help me!

  • Trying to draw a dynamic rectangle in SVG

    - by Shaun
    To be more specific, here are the steps I need: onmousedown - set x and y of rect as mouse coordinates onmousemove - using the current x and y mouse coordinates calculate height and width of the rect, set these and append onmouseup - remove the rectangle, and call a function based off some calculations from the rect. Here is what I have but isn't quite working (right now I have it drawing a line to make it simpler): onmousedown: startbox(evt) function startbox(evt) { if(evt.button === 0) { x1 = evt.clientX + div.scrollLeft-5; y1 = evt.clientY + div.scrollTop-30; obj.setAttributeNS(null, "x1", x1); obj.setAttributeNS(null, "y1", y1); Root.setAttributeNS(null, "onmousemove", "updatebox(evt)"); } } onmousemove: updatebox(evt) function updatebox(evt) { if(evt.button === 0) { x2 = evt.clientX + div.scrollLeft-5; y2 = evt.clientY + div.scrollTop-30; Root.appendChild(.obj); w = Math.abs(x2-x1); h = Math.abs(y2-y1); var strokecolor; if(w>20 && h>20) { strokecolor = "green"; validbox = true; } else { strokecolor = "red"; validbox = false; } var Attr={ x2:x2, y2:y2, stroke:strokecolor } assignAttr(obj, Attr); //just loops thru adding multiple attributes } } onmouseup: endbox() function endbox(evt) { if(evt.button===0) { Root.setAttributeNS(null, "onmousemove", ""); Root.removeChild(obj); if(validbox) { //do stuff validbox = !validbox; } } } Some of my problems with this are: Its slow in Chrome making drawing the line/rect feel sluggish. It won't work two times in a row. This is the real problem that I can't fix. Any and all feedback is welcome.

  • Jquery Cycle Lite plugin unable to see images that have been loaded by an AJAX call

    - by William Macdonald
    Hi, I am having problems using the jquery cycle lite plugin on some images that are added via AJAX. Here is the jquery code: $(function() { resizeWindow(); $(window).bind("resize", resizeWindow); $("#assignment-nav").accordion({ header: "h3", autoHeight: false }); $(".project").click(function() { // get the HTML and load into div $('.image-holder').empty(); var justTheNumber = $(this).attr('id').replace('project-',''); $.get("get_project_images.php", {project_id:justTheNumber}, function(data){ $('.image-holder').append(data); } ); $(".image-holder").cycle({ // Cycle plugin prev: '#prev', next: '#next', timeout: 0, speed: 250 }) }); }); My code works fine in that the IMG tags are loaded and the first image of the slide show is displayed. However the prev/next buttons don't work. When I load the images via static HTML the slideshow prev/next links works fine. (I just copied and pasted the generated HTML.) I understand I need to use something like .bind or .live to make the Cycle plugin 'see' the new images. I have tried everything I can think of but I can't make it work. What am I doing wrong ?

  • Adding a block of XML as child of a SimpleXMLElement object

    - by miCRoSCoPiC_eaRthLinG
    Hey all, I have this SimpleXMLElement object with a XML setup similar to the following... $xml <<< EOX <books> <book> <name>ABCD</name> </book> </books> EOX; $sx = new SimpleXMLElement( $xml ); Now I have a class named Book that contains info. about each book. The same class can also spit out the book info. in XML format akin the the above (the nested block).. example, $book = new Book( 'EFGH' ); $book->genXML(); ... will generate <book> <name>EFGH</name> </book> Now I'm trying to figure out a way by which I can use this generated XML block and append as a child of so that now it looks like... for example.. // Non-existent member method. For illustration purposes only. $sx->addXMLChild( $book->genXML() ); ...XML tree now looks like: <books> <book> <name>ABCD</name> </book> <book> <name>EFGH</name> </book> </books> From what documentation I have read on SimpleXMLElement, addChild() won't get this done for you as it doesn't support XML data as tag value. Any ideas on how I should go about this ? Thanks, m^e

  • asyncore callbacks launching threads... ok to do?

    - by sbartell
    I'm unfamiliar with asyncore, and have very limited knowledge of asynchronous programming except for a few intro to twisted tutorials. I am most familiar with threads and use them in all my apps. One particular app uses a couchdb database as its interface. This involves longpolling the db looking for changes and updates. The module I use for couchdb is couchdbkit. It uses an asyncore loop to watch for these changes and send them to a callback. So, I figure from this callback is where I launch my worker threads. It seems a bit crude to mix asynchronous and threaded programming. I really like couchdbkit, but would rather not introduce issues into my program. So, my question is, is it safe to fire threads from an async callback? Here's some code... {{{ def dispatch(change): global jobs, db_url # jobs is my queue db = Database(db_url) work_order = db.get(change['id']) # change is an id to the document that changed. # i need to get the actual document (workorder) worker = Worker(work_order, db) # fire the thread jobs.append[worker] worker.start() return main() . . . consumer.wait(cb=dispatch, since=update_seq, timeout=10000) #wait constains the asyncloop. }}}

  • Comparing dicts and update a list of result

    - by lmnt
    Hello, I have a list of dicts and I want to compare each dict in that list with a dict in a resulting list, add it to the result list if it's not there, and if it's there, update a counter associated with that dict. At first I wanted to use the solution described at http://stackoverflow.com/questions/1692388/python-list-of-dict-if-exists-increment-a-dict-value-if-not-append-a-new-dict but I got an error where one dict can not be used as a key to another dict. So the data structure I opted for is a list where each entry is a dict and an int: r = [[{'src': '', 'dst': '', 'cmd': ''}, 0]] The original dataset (that should be compared to the resulting dataset) is a list of dicts: d1 = {'src': '192.168.0.1', 'dst': '192.168.0.2', 'cmd': 'cmd1'} d2 = {'src': '192.168.0.1', 'dst': '192.168.0.2', 'cmd': 'cmd2'} d3 = {'src': '192.168.0.2', 'dst': '192.168.0.1', 'cmd': 'cmd1'} d4 = {'src': '192.168.0.1', 'dst': '192.168.0.2', 'cmd': 'cmd1'} o = [d1, d2, d3, d4] The result should be: r = [[{'src': '192.168.0.1', 'dst': '192.168.0.2', 'cmd': 'cmd1'}, 2], [{'src': '192.168.0.1', 'dst': '192.168.0.2', 'cmd': 'cmd2'}, 1], [{'src': '192.168.0.2', 'dst': '192.168.0.1', 'cmd': 'cmd1'}, 1]] What is the best way to accomplish this? I have a few code examples but none is really good and most is not working correctly. Thanks for any input on this! UPDATE The final code after Tamås comments is: from collections import namedtuple, defaultdict DataClass = namedtuple("DataClass", "src dst cmd") d1 = DataClass(src='192.168.0.1', dst='192.168.0.2', cmd='cmd1') d2 = DataClass(src='192.168.0.1', dst='192.168.0.2', cmd='cmd2') d3 = DataClass(src='192.168.0.2', dst='192.168.0.1', cmd='cmd1') d4 = DataClass(src='192.168.0.1', dst='192.168.0.2', cmd='cmd1') ds = d1, d2, d3, d4 r = defaultdict(int) for d in ds: r[d] += 1 print "list to compare" for d in ds: print d print "result after merge" for k, v in r.iteritems(): print("%s: %s" % (k, v))

  • Global and local variables in my script

    - by Acorn
    I'm starting out learning javascript, and tried to write a little script that would make a grid of divs on a page. Here's the script: var tileWidth=50; var tileHeight=100; var leftPos=10; var topPos=10; var columns=10; var rows=10; var spacing=5; $('document').ready(function() { placeTiles(); }); function makeRow() { for (var i=0; i<columns; i++) { $('#canvas').append('<div class="tile" style="left:' + leftPos + 'px;top:' + topPos + 'px;"></div>'); var leftPos = leftPos + tileWidth + spacing; } } function placeTiles() { for (var i=0; i<rows; i++) { makeRow(); var topPos = topPos + tileHeight + spacing; } } At the moment, 100 <div>s get created, all with a top position of 10px and a left position of undefined (for the first <div> in the row) or NaN. What should I be doing differently? Why can't makerow() see my global leftPos variable (and all the other variables for that matter)? Thanks.

  • jquery post and get request different on local intranet and live server

    - by nccsbim071
    Hi, I have been developing an asp.net mvc application where i need to make large amounts of jquery post and get request to call controller methods and get back json result. Everything is working fine. The problem is i had to write different jquery post and get request url on local intranet(deployed by making virtual directory) and live server. the current jquery request url is given as below: $.post("/ProjectsChat/GetMessages", { roomId: 24 },.......... now this format of url for jquery request works fine for live server but not for local intranet. Since on local intranet i have made a virtual directory. It only works when i append the name of the virtual directory like this "$.post("MyProjectVirutalDirName/ProjectsChat..................." I am sure most of you must have come across same problem. now i have made a full project, there are large number of jquery requests made, i want to test the application by deploying on local intranet and fix the bugs. Changing all the jquery requests for local intranet doesn't seem feasible solution to me, i am really in a big problem, i can't deploy the same project on live server just like that and test it there, client will kill me. I need some expert advice. Please help Thanks

  • Getting table schema from a query

    - by Appu
    As per MSDN, SqlDataReader.GetSchemaTable returns column metadata for the query executed. I am wondering is there a similar method that will give table metadata for the given query? I mean what tables are involved and what aliases it has got. In my application, I get the query and I need to append the where clause programically. Using GetSchemaTable(), I can get the column metadata and the table it belongs to. But even though table has aliases, it still return the real table name. Is there a way to get the aliase name for that table? Following code shows getting the column metadata. const string connectionString = "your_connection_string"; string sql = "select c.id as s,c.firstname from contact as c"; using(SqlConnection connection = new SqlConnection(connectionString)) using(SqlCommand command = new SqlCommand(sql, connection)) { connection.Open(); SqlDataReader reader = command.ExecuteReader(CommandBehavior.KeyInfo); DataTable schema = reader.GetSchemaTable(); foreach (DataRow row in schema.Rows) { foreach (DataColumn column in schema.Columns) { Console.WriteLine(column.ColumnName + " = " + row[column]); } Console.WriteLine("----------------------------------------"); } Console.Read(); } This will give me details of columns correctly. But when I see BaseTableName for column Id, it is giving contact rather than the alias name c. Is there any way to get the table schema and aliases from a query like the above? Any help would be great!

  • ANT propertyfile entry is not resolving to its value

    - by Brian
    I have a value in a properties file that I want to increment while the build is running. The goal is to copy a set of files and append a number to the front of each in order to maintain the order in which they were copied into the directory. I am using the <propertyfile> task as follows: <propertyfile file="jsfiles.properties"> <entry key="file.number" type="int" operation="=" value="10" /> <entry key="file.number" type="int" default="010" operation="+" value="10" pattern="000" /> </propertyfile> Then I do the copy: <copy todir="${js-in.dir}"> <resources> ... </resources> <chainedmapper> <flattenmapper /> <globmapper from="*.js" to="${file.number}-*.js"/> </chainedmapper> </copy> This does exactly what I need it to EXCEPT that instead of the following output: 010-file1.js 020-file2.js 030-file3.js ... I get: ${file.number}-file1.js ${file.number}-file2.js ${file.number}-file3.js ... What am I doing wrong?

  • Why do I get empty request from the Jakarta Commons HttpClient?

    - by polyurethan
    I have a problem with the Jakarta Commons HttpClient. Before my self-written HttpServer gets the real request there is one request which is completely empty. That's the first problem. The second problem is, sometimes the request data ends after the third or fourth line of the http request: POST / HTTP/1.1 User-Agent: Jakarta Commons-HttpClient/3.1 Host: 127.0.0.1:4232 For debugging I am using the Axis TCPMonitor. There every things is fine but the empty request. How I process the stream: StringBuffer requestBuffer = new StringBuffer(); InputStreamReader is = new InputStreamReader(socket.getInputStream(), "UTF-8"); int byteIn = -1; do { byteIn = is.read(); if (byteIn > 0) { requestBuffer.append((char) byteIn); } } while (byteIn != -1 && is.ready()); String requestData = requestBuffer.toString(); How I send the request: client.getParams().setSoTimeout(30000); method = new PostMethod(url.getPath()); method.getParams().setContentCharset("utf-8"); method.setRequestHeader("Content-Type", "application/xml; charset=utf-8"); method.addRequestHeader("Connection", "close"); method.setFollowRedirects(false); byte[] requestXml = getRequestXml(); method.setRequestEntity(new InputStreamRequestEntity(new ByteArrayInputStream(requestXml))); client.executeMethod(method); int statusCode = method.getStatusCode(); Have anyone of you an idea how to solve these problems?

  • Pseudo-quicksort time complexity

    - by Ord
    I know that quicksort has O(n log n) average time complexity. A pseudo-quicksort (which is only a quicksort when you look at it from far enough away, with a suitably high level of abstraction) that is often used to demonstrate the conciseness of functional languages is as follows (given in Haskell): quicksort :: Ord a => [a] -> [a] quicksort [] = [] quicksort (p:xs) = quicksort [y | y<-xs, y<p] ++ [p] ++ quicksort [y | y<-xs, y>=p] Okay, so I know this thing has problems. The biggest problem with this is that it does not sort in place, which is normally a big advantage of quicksort. Even if that didn't matter, it would still take longer than a typical quicksort because it has to do two passes of the list when it partitions it, and it does costly append operations to splice it back together afterwards. Further, the choice of the first element as the pivot is not the best choice. But even considering all of that, isn't the average time complexity of this quicksort the same as the standard quicksort? Namely, O(n log n)? Because the appends and the partition still have linear time complexity, even if they are inefficient.

  • Django repeating vars/cache issue?

    - by Mark
    I'm trying to build a better/more powerful form class for Django. It's working well, except for these sub-forms. Actually, it works perfectly right after I re-start apache, but after I refresh the page a few times, my HTML output starts to look like this: <input class="text" type="text" id="pickup_addr-pickup_addr-pickup_addr-id-pickup_addr-venue" value="" name="pickup_addr-pickup_addr-pickup_addr-pickup_addr-venue" /> The pickup_addr- part starts repeating many times. I was looking for loops around the prefix code that might have cause this to happen, but the output isn't even consistent when I refresh the page, so I think something is getting cached somewhere, but I can't even imagine how that's possible. The prefix car should be reset when the class is initialized, no? Unless it's somehow not initializing something? class Form(object): count = 0 def __init__(self, data={}, prefix='', action='', id=None, multiple=False): self.fields = {} self.subforms = {} self.data = {} self.action = action self.id = fnn(id, 'form%d' % Form.count) self.errors = [] self.valid = True if not empty(prefix) and prefix[-1:] not in ('-','_'): prefix += '-' for name, field in inspect.getmembers(self, lambda m: isinstance(m, Field)): if name[:2] == '__': continue field_name = fnn(field.name, name) field.label = fnn(field.label, humanize(field_name)) field.name = field.widget.name = prefix + field_name + ife(multiple, '[]') field.id = field.auto_id = field.widget.id = ife(field.id==None, 'id-') + prefix + fnn(field.id, field_name) + ife(multiple, Form.count) field.errors = [] val = fnn(field.widget.get_value(data), field.default) if isinstance(val, basestring): try: val = field.coerce(field.format(val)) except Exception, err: self.valid = False field.errors.append(escape_html(err)) field.val = self.data[name] = field.widget.val = val for rule in field.rules: rule.fields = self.fields rule.val = field.val rule.name = field.name self.fields[name] = field for name, form in inspect.getmembers(self, lambda m: ispropersubclass(m, Form)): if name[:2] == '__': continue self.subforms[name] = self.__dict__[name] = form(data=data, prefix='%s%s-' % (prefix, name)) Form.count += 1 Let me know if you need more code... I know it's a lot, but I just can't figure out what's causing this!

(function($) { var methods = { init: function(options) { var defaults = { bgClass: "fancy-dialog-bg", bgShow: null, zIndex: 100, show: null }; var settings = $.extend(defaults, options); return this.each(function() { var obj = $(this).hide().css("position", "fixed").css("z-index", settings.zIndex).css("left", "300px").css("top", "200px"); }); }, open: function() { // alert(settings.zIndex); not working var tes = $("<div></div>").css("backgroundColor", "#f00").css("position", "fixed").css("z-index", "99").css("width", "50%").css("height", "100%").css("left", "0").css("top", "0"); $('body').append(tes); var obj = $(this); obj.show(); }, close: function() { var obj = $(this); $("#fancy-dialog-bg-" + obj.attr('id')).remove(); obj.hide(); } }; $.fn.fancyDialog = function(method) { if (methods[method]) { return methods[method].apply(this, Array.prototype.slice.call(arguments, 1)); } else if (typeof method === 'object' || !method) { return methods.init.apply(this, arguments); } else { $.error('Method ' + method + ' does not exist.'); } }; })(jQuery);

  • Bash script to insert code from one file at a specific location in another file?

  • Server returns 500 error only when called by Java client using urlConnection/httpUrlConnection

    - by user455889
    Hi - I'm having a very strange problem. I'm trying to call a servlet (JSP) with an HTTP GET and a few parameters (http://mydomain.com/method?param1=test&param2=123). If I call it from the browser or via WGET in a bash session, it works fine. However, when I make the exact same call in a Java client using urlConnection or httpURLConnection, the server returns a 500 error. I've tried everything I have found online including: urlConn.setRequestProperty("Accept-Language", "en-us,en;q=0.5"); Nothing I've tried, however, has worked. Unfortunately, I don't have access to the server I'm calling so I can't see the logs. Here's the latest code: private String testURLConnection() { String ret = ""; String url = "http://localhost:8080/TestService/test"; String query = "param1=value1&param2=value2"; try { URLConnection connection = new URL(url + "?" + query).openConnection(); connection.setRequestProperty("Accept-Charset", "UTF-8"); connection.setRequestProperty("Accept-Language", "en-us,en;q=0.5"); BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream())); String line; StringBuilder content = new StringBuilder(); while ((line = bufferedReader.readLine()) != null) { content.append(line + "\n"); } bufferedReader.close(); metaRet = content.toString(); log.debug(methodName + " return = " + metaRet); } catch (Exception ex) { log.error("Exception: " + ex); log.error("stack trace: " + getStackTrace(ex)); } return metaRet; } Any help would be greatly appreciated!

  • I would like to know how to put a "change image" layer like in facebook on a mouseover event

    - by netadictos
    Hello: I have a photo gallery I would like that every time a user does mouseover the image, there is a button on the top of this image that appears. The user can click on it. But every time that the user mouse out of the photo it must disappear. It works like the "change photo" in Facebook, with the photo of your profile. The problem I am having is that when I try to get over the button that appears (in my code is a link), it disappear because javascript understands that the mouse is just out of the image, even if this button/link is over the image. The image that I use is positioned absolutely over the image. This is my code, where you can see that I create a dom element that I append on the link of the image and then when there is a mouseout, I remove it. $('a.ftelement').mouseover(function() { var fav = $('<a></a>'); fav.attr("class","imgfavorito"); fav.attr("id","fav"+$J(this).attr("id")).html("<img src=\"/im/favorito.gif\"/>"); fav.appendTo(this); }); $('a.ftelement').mouseout(function() { $("a.imgfavorito").remove() }); The result is this graphically (http://www.freeimagehosting.net/uploads/41fbac8994.gif):

  • How to use setTimeout / .delay() to wait for typing between characters

    - by Darcy
    Hi all, I am creating a simple listbox filter that takes the user input and returns the matching results in a listbox via javascript/jquery (roughly 5000+ items in listbox). Here is the code snippet: var Listbox1 = $('#Listbox1'); var commands = document.getElementById('DatabaseCommandsHidden'); //using js for speed $('#CommandsFilter').bind('keyup', function() { Listbox1.children().remove(); for (var i = 0; i < commands.options.length; i++) { if (commands.options[i].text.toLowerCase().match($(this).val().toLowerCase())) { Listbox1.append($('<option></option>').val(i).html(commands.options[i].text)); } } }); This works pretty well, but slows down somewhat when the 1st/2nd char's are being typed since there are so many items. I thought a solution I could use would be to add a delay to the textbox that prevents the 'keyup' event from being called until the user stops typing. The problem is, I'm not sure how to do that, or if its even a good idea or not. Any suggestions/help is greatly appreciated.

  • How to efficiently convert String, integer, double, datetime to binary and vica versa?

    - by Ben
    Hi, I'm quite new to C# (I'm using .NET 4.0) so please bear with me. I need to save some object properties (their properties are int, double, String, boolean, datetime) to a file. But I want to encrypt the files using my own encryption, so I can't use FileStream to convert to binary. Also I don't want to use object serialization, because of performance issues. The idea is simple, first I need to somehow convert objects (their properties) to binary (array), then encrypt (some sort of xor) the array and append it to the end of the file. When reading first decrypt the array and then somehow convert the binary array back to object properties (from which I'll generate objects). I know (roughly =) ) how to convert these things by hand and I could code it, but it would be useless (too slow). I think the best way would be just to get properties' representation in memory and save that. But I don't know how to do it using C# (maybe using pointers?). Also I though about using MemoryStream but again I think it would be inefficient. I am thinking about class Converter, but it does not support toByte(datetime) (documentation says it always throws exception). For converting back I think the only options is class Converter. Note: I know the structure of objects and they will not change, also the maximum String length is also known. Thank you for all your ideas and time. EDIT: I will be storing only parts of objects, in some cases also parts of different objects (a couple of properties from one object type and a couple from another), thus I think that serialization is not an option for me.

  • Parsing HTTP - Bytes.length != String.length

    - by hotzen
    Hello, I consume HTTP via nio.SocketChannel, so I get chunks of data as Array[Byte]. I want to put these chunks into a parser and continue parsing after each chunk has been put. HTTP itself seems to use an ISO8859-Charset but the Payload/Body itself may be arbitrarily encoded: If the HTTP Content-Length specifies X bytes, the UTF8-decoded Body may have much less Characters (1 Character may be represented in UTF8 by 2 bytes, etc). So what is a good parsing strategy to honor an explicitly specified Content-Length and/or a Transfer-Encoding: Chunked which specifies a chunk-length to be honored. append each data-chunk to an mutable.ArrayBuffer[Byte], search for CRLF in the bytes, decode everything from 0 until CRLF to String and match with Regular-Expressions like StatusRegex, HeaderRegex, etc? decode each data-chunk with the proper charset (e.g. iso8859, utf8, etc) and add to StringBuilder. With this solution I am not able to honor any Content-Length or Chunk-Size, but.. do I have to care for it? any other solution... ?
