• [PHP] DOMDocument load on a page returning 400 Bad Request status

  - by PeteWilliams

  Hiya, I'm trying to use the Last.fm API for an application I'm creating, but am having some problems with validation. If an API request gives an error it returns a code and message in the response XML like this: <lfm status="failed"> <error code="6">No user with that name</error> </lfm> However, the request also returns an HTTP status of 400 (or in some cases 403) which DOMDocument considers an error and so then refuses to parse the XML. Is there any way round this, so that I can retrieve the error code and message? Thanks Pete

• Git tutorial: Understanding git pull and branches (using a specific example repo)

  - by dreftymac

  Backround: Suppose I have the following Git URLs (hosted on github) http://github.com/mikl/drupal.git git://github.com/mikl/drupal.git (Git read-only) I am interested in having a local copy of this repository so I can pratice working with branches in git and see how my local working tree can change depending on which branch I am working with. Questions: To get started, I set up a local directory and do git clone git://github.com/mikl/drupal.git ... Will this clone all of the branches? Or will it only clone master? The web front-end for github gives me a "drop down" menu that allows me to switch branches ... Does changing this drop-down actually change which branch I will be grabbing when I run git clone? If I want a new copy of this repository on my local machine, but I am interested in only two branches of this repository and I want to ignore all the rest, what command do I use to ensure I clone only those two branches and nothing else (assume one of the branches is master)?

• A tool to find and fix incomplete source code documentation

  - by Pekka

  I have several finished, older PHP projects with a lot of includes that I would like to document in javadoc/phpDocumentor style. While working through each file manually and being forced to do a code review alongside the documenting would be the best thing, I am, simply out of time constraints, interested in tools to help me automate the task as much as possible. The tool I am thinking about would ideally have the following features: Parse a PHP project tree and tell me where there are undocumented files, classes, and functions/methods (i.e. elements missing the appropriate docblock comment) Provide a method to half-way easily add the missing docblocks by creating the empty structures and, ideally, opening the file in an editor (internal or external I don't care) so I can put in the description. Optional: Automatic recognition of parameter types, return values and such. But that's not really required. The language in question is PHP, though I could imagine that a C/Java tool might be able to handle PHP files after some tweaking. Thanks for your great input!

• [Gdata] GetAuthSubToken returns None

  - by Matt

  Hey guys, I am a little lost on how to get the auth token. Here is the code I am using on the return from authorizing my app: client = gdata.service.GDataService() gdata.alt.appengine.run_on_appengine(client) sessionToken = gdata.auth.extract_auth_sub_token_from_url(self.request.uri) client.UpgradeToSessionToken(sessionToken) logging.info(client.GetAuthSubToken()) what gets logged is "None" so that does seem right :-( if I use this: temp = client.upgrade_to_session_token(sessionToken) logging.info(dump(temp)) I get this: {'scopes': ['http://www.google.com/calendar/feeds/'], 'auth_header': 'AuthSub token=CNKe7drpFRDzp8uVARjD-s-wAg'} so I can see that I am getting a AuthSub Token and I guess I could just parse that and grab the token but that doesn't seem like the way things should work. If I try to use AuthSubTokenInfo I get this: Traceback (most recent call last): File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/ext/webapp/__init__.py", line 507, in __call__ handler.get(*groups) File "controllers/indexController.py", line 47, in get logging.info(client.AuthSubTokenInfo()) File "/Users/matthusby/Dropbox/appengine/projects/FBCal/gdata/service.py", line 938, in AuthSubTokenInfo token = self.token_store.find_token(scopes[0]) TypeError: 'NoneType' object is unsubscriptable so it looks like my token_store is not getting filled in correctly, is that something I should be doing? Also I am using gdata 2.0.9 Thanks Matt

• Notepad++ Associate custom ext for use by ctags

  - by user185420

  Hi, I use .pkb and pkh extensions for PL/SQL files (rather than .sql). I have already associated .pkb and .pkh extension in the langs.xml (Styler Config) so that Notepad++ recognizes the syntax highlight to use when I open pkb and pkh files (the syntax highlighting would be the same as for sql ext). Now the problem is that I cannot use plugins that parse code using ctags (like SourceCookifier, OpenCtag,GtagSearch) because these plugins do not recognize the pkb and pkh extension. THe only way I could use them is to change my file to sql and when done change to the pkh or pkb ext. Is there any config that could make ctags based plugin work with non-sql ext? I tried changing various config for the plugins but did not succeed in making them work. Thanks.

• Parsing Indentation-based syntaxes in Haskell's Parsec

  - by pavpanchekha

  I'm trying to parse an indentation-based language (think Python, Haskell itself, Boo, YAML) in Haskell using Parsec. I've seen the IndentParser library, and it looks like it's the perfect match, but what I can't figure out is how to make my TokenParser into an indentation parser. Here's the code I have so far: import qualified Text.ParserCombinators.Parsec.Token as T import qualified Text.ParserCombinators.Parsec.IndentParser.Token as IT lexer = T.makeTokenParser mylangDef ident = IT.identifier lexer This throws the error: parser2.hs:29:28: Couldn't match expected type `IT.TokenParser st' against inferred type `T.GenTokenParser s u m' In the first argument of `IT.identifier', namely `lexer' In the expression: IT.identifier lexer In the definition of `ident': ident = IT.identifier lexer What am I doing wrong? How should I create an IT.TokenParser? Or is IndentParser broken and to be avoided?

• What are some tips for troubleshooting builds of complicated software?

  - by Goose Bumper

  Sometimes I want to build Python or GCC from scratch just for fun, but I can't parse the errors I get, or don't understand statements like "libtool link error # XYZ". What are some tricks that unix/systems gurus use to compile software of this size from scratch? Of course I already do things like read config.log (if there is one), google around, and post in newsgroups. I'm looking for things that either make the process go smoother or get me more information about the error to help me understand and fix it. It's a little tough to get this information sometimes, because some compile bugs can be quite obscure. What can I do at that point?

• Which GUI control is suitable for this purpose?

  - by pecker

  Hello, I'm using winforms of .NET & C#. I'm developing a medical software. I need to implement "Patient History". When doctor enters the PatientID. All the previous appointment dates will be displayed in a side panel. These entries will dynamically fetched from the database. Interface will be more or less similar to Histroy in web browser. Except that I'm not going to use tree control and categorize entries into 'today' 'yesterday' 'older than 7 days' 'last week' etc.. What controls do I need to use. I'm not clear about this. If you have any better idea. Please mention.

• NHibernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy

• How can I store data in a table as a trie? (SQL Server)

  - by Matt

  Hi, To make things easier, the table contains all the words in the English dictionary. What I would like to do is be able to store the data as a trie. This way I can traverse the different branches of the trie and return the most relevant result. First, how do I store the data in the table as a trie? Second, how do I traverse the tree? If it helps at all, the suggestion in this previous question is where this question was sparked from. Please make sure it's SQL we're talking about. I understood the Mike Dunlavey's C implementation because of pointers but can't see how this part (The trie itself) works in SQL. Thanks, Matt

• writing a fast parser in python

  - by panzi

  I've written a hands-on recursive pure python parser for a some file format (ARFF) we use in one lecture. Now running my exercise submission is awfully slow. Turns out by far the most time is spent in my parser. It's consuming a lot of CPU time, the HD is not the bottleneck. I wonder what performant ways are there to write a parser in python? I'd rather not rewrite it in C. I tried to use jython, but that decreased performance a lot! The files I parse are partially huge ( 150 MB) with very long lines. My current parser only needs a look-ahead of one character. I'd post the source here but I don't know if that's such a good idea. After all the submission deadline has not jet ended. But then, the focus in this exercise is not the parser. You can choose whatever language you want to use and there already is a parser for Java.

• Generate canonical / real URL based on base.href or location

  - by blueyed

  Is there a method/function to get the canonical / transformed URL, respecting any base.href setting of the page? I can get the base URL via (in jQuery) using $("base").attr("href") and I could use string methods to parse the URL meant to being made relative to this, but $("base").attr("href") has no host, path etc attributes (like window.location has) manually putting this together is rather tedious E.g., given a base.href of "http://example.com/foo/" and a relative URL "/bar.js", the result should be: "http://example.com/bar.js" If base.href is not present, the URL should be made relative to window.location. This should handle non-existing base.href (using location as base in this case). Is there a standard method available for this already? (I'm looking for this, since jQuery.getScript fails when using a relative URL like "/foo.js" and BASE tag is being used (FF3.6 makes an OPTIONS request, and nginx cannot handle this). When using the full URL (base.href.host + "/foo.js", it works).)

• How can I handle template dependencies in Template Toolkit?

  - by Smack my batch up

  My static web pages are built from a huge bunch of templates which are inter-included using Template Toolkit's "import" and "include", so page.html looks like this: [% INCLUDE top %] [% IMPORT middle %] Then top might have even more files included. I have very many of these files, and they have to be run through to create the web pages in various languages (English, French, etc., not computer languages). This is a very complicated process and when one file is updated I would like to be able to automatically remake only the necessary files, using a makefile or something similar. Are there any tools like makedepend for C files which can parse template toolkit templates and create a dependency list for use in a makefile? Or are there better ways to automate this process?

• How to get video file details eg. duration in Android?

  - by spirytus

  I struggle to get specific video file details so duration etc. from the file the files recorded earlier. All I can currently do is to get cursor with all the files, then loop one by one. Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), MediaStore.Video.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); if(cursor.moveToFirst()) while(!cursor.isLast()){ if(cursor.getString(3)==fight.filename) { // do something here } cursor.moveToNext(); } I need however to access details of specific files so I tried to create URI but no luck as cursor returned is always null. Where do I go wrong? Uri uri = Uri.parse(Environment.DIRECTORY_DCIM+"/FightAll_BJJ_Scoring/"+(fight.filename)); Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), uri, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); // cursor is always null here

• Playing around with Eclipse features - Project files are now hidden?

  - by Daddy Warbox

  I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden trees altogether expanding when I click on any item, and the entire file folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?

Any hints ? Thanks.

• Strcpy() corrupts the copied string in Solaris but not Linux

  - by strictlyrude27

  Hi all, I'm writing a C code for a class. This class requires that our code compile and run on the school server, which is a sparc solaris machine. I'm running Linux x64. I have this line to parse (THIS IS NOT ACTUAL CODE BUT IS INPUT TO MY PROGRAM): while ( cond1 ){ I need to capture the "while" and the "cond1" into separate strings. I've been using strtok() to do this. In Linux, the following lines: char *cond = NULL; cond = (char *)malloc(sizeof(char)); memset(cond, 0, sizeof(char)); strcpy(cond, strtok(NULL, ": \t\(){")); //already got the "while" out of the line will correctly capture the string "cond1".Running this on the solaris machine, however, gives me the string "cone1". Note that in plenty of other cases within my program, strings are being copied correctly. (For instance, the "while") was captured correctly. Does anyone know what is going on here?

• Inserting Newline from XML to Database

  - by blackmage

  I am trying to parse this xml document in which a newline is required for certain fields and must be inserted into the database with the newline. But I've been running into problems. 1)First Problem: \n Character The first problem I had was using the \n like below. <javascript>jquery_ui.js\nshadowbox_modal.js\nuser_profile.js\ntablesorter.js</javascript> The problem was in the database the field came out ot be jquery_ui.js\nshadowbox_modal.js\n... and when output into html it was jquery_ui.jsnshadowbox_modal.jsn............... 2) Then I tried actually having newlines in the xml <javascript>jquery_ui.js shadowbox_modal.js user_profile.js tablesorter.js</javascript> The problem was the output become %20%20%20%20%20%20%20%20%20%20shadowbox_modal.js, and so forth. So how can I get a newline to hold from xml when entered into a database and then output with the newline still?

• Tokenizer for full-text

  - by user72185

  This should be an ideal case of not re-inventing the wheel, but so far my search has been in vain. Instead of writing one myself, I would like to use an existing C++ tokenizer. The tokens are to be used in an index for full text searching. Performance is very important, I will parse many gigabytes of text. Edit: Please note that the tokens are to be used in a search index. Creating such tokens is not an exact science (afaik) and requires some heuristics. This has been done a thousand time before, and probably in a thousand different ways, but I can't even find one of them :) Any good pointers? Thanks!

• boost::Spirit Grammar for unsorted schema

  - by Hassan Syed

  I have a section of a schema for a model that I need to parse. Lets say it looks like the following. { type = "Standard"; hostname="x.y.z"; port="123"; } The properties are: The elements may appear unordered. All elements that are part of the schema must appear, and no other. All of the elements' synthesised attributes go into a struct. (optional) The schema might in the future depend on the type field -- i.e., different fields based on type -- however I am not concerned about this at the moment.

• How do I use a Rails ActiveRecord migration to insert a primary key into a MySQL database?

  - by Terry Lorber

  I need to create an AR migration for a table of image files. The images are being checked into the source tree, and should act like attachment_fu files. That being the case, I'm creating a hierarchy for them under /public/system. Because of the way attachment_fu generates links, I need to use the directory naming convention to insert primary key values. How do I override the auto-increment in MySQL as well as any Rails magic so that I can do something like this: image = Image.create(:id => 42, :filename => "foo.jpg") image.id #=> 42
