• Why won't Heroku accept my Gemfile.lock in Windows?

  - by mranders

  I have a rails application that I deploy on Heroku. I'm using several different machines, and I noticed that when I add new dependencies (so that Gemfile.lock is rebuilt) and do bundle install on my Windows computer at home, push to Heroku fails with the following error: Unresolved dependencies detected; Installing... Windows Gemfile.lock detected, ignoring it. You have modified your Gemfile in development but did not check the resulting snapshot (Gemfile.lock) into version control ... Gemfile.lock IS under version control, but Heroku appearently chooses to ignore it since it's created in Windows, and then complains that it's missing seconds later. Why does this happen? And how can I solve it?

• Error preverifying class java during build (BlackBerry)

  - by Davide Vosti

  I'm trying do build and debug a small project for BlackBerry. During the build I'm getting this error Error preverifying class java ... I read on the net this error could be caused by referencing multiple projects but I tried to move every package in a single project but the error is still there. I tried with multiple JDE version (currently 4.7) and the Java compiler is set to 1.6. Eclipse version is 3.4.1 as recommended by RIM's documentations. Does someone have some clue?

• XSLT 2.0 Header Leaks into Transformed XML

  - by user1303797

  First, a thank you in advance. Second, this is my first post so apologies for any errors or wrongdoings. I am a noob w/ xml and xslt, and can't seem to figure this out. When I transform some xml using xslt 2.0, some of the headers from the xslt leaks into the new xml. It doesn't seem to do it in xslt 1.0 (granted the xslt is a little different). Here is the xml: <?xml version="1.0" encoding="ISO-8859-1" ?> <xml_content> <feed_name>feed</feed_name> <feed_info> <entry_1> <id>1</id> <pub_date>1320814800</pub_date> </entry_1> </feed_info> </xml_content> Here is the xslt: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <xsl:output method="xml" indent="yes" /> <xsl:template match="xml_content"> <Records> <xsl:for-each select="feed_info/entry_1"> <Record> <ID><xsl:value-of select="id" /></ID> <PublicationDate><xsl:value-of select='xs:dateTime("1970-01-01T00:00:00") + xs:integer(pub_date) * xs:dayTimeDuration("PT1S")'/></PublicationDate> </Record> </xsl:for-each> </Records> </xsl:template> </xsl:stylesheet> Here is the new xml. Look specifically at the first "Records" element. <?xml version="1.0" encoding="UTF-8"?> <Records xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <Record> <ID>1</ID> <PublicationDate>2011-11-09T05:00:00</PublicationDate> </Record> </Records>

• How to pass parameter value to XSL?

  - by Manish

  Suppose I have a XSL as follows: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="html" encoding="utf-8" omit-xml-declaration="yes" indent="yes"/> <xsl:param name="sortKey" select="'firstname'"/> </xsl:stylesheet> Then a XML as follows <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <?xml-stylesheet type="text/xsl" href="XYZ.xsl"?> <ABC> </ABC> I want to pass a value to the XSL parameter firstname from XML. Can I do that? If yes, How? I'm not sure if I'm correct and this can be done.

• How can I deal with the ICE60 warning in WiX?

  - by Scott Boettger

  Good Afternoon, I have created a WiX project that installs a bunch of different EXEs and DLLs. Unfortunatly when I build the project I receive the following warning for each one of them: ICE60: The file fileName is not a Font, and its version is not a companion file reference. It should have a language specified in the Language column. I have found examples and possible solutions for this and each time it is suggested to set the DefaultLanguage tag to 0 in order to fix the warning. Once doing that I then get this warning: The DefaultLanguage '0' was used for file 'fileName' which has no language or version. For unversioned files, specifying a value for DefaultLanguage is not neccessary and it will not be used when determining file versions. Remove the DefaultLanguage attribute to eliminate this warning. So this leads me to the question of how can I handle this warning? Thanks in advance for any and all help given.

• Suggestions for a good IDE for DB2

  - by ken

  Hi all, I know, I know... it's a horrible fate but I am forced to work in an environment with DB2 on the back end. OK just kidding but the truth is I do like MSSQL's data studio a lot, and well IBM's tool is sorda crummy in my opinion... I was using the free version of Toad but I just got a new 64bit machine which is nice and all but there isn't a free version of Toad that I can find for win7 64. Does anyone have any suggestions for a good IDE to use with DB2? Being a developer I really just do a lot of looking at the DB structure and querying to see what I get back and how I want to get things back etc... Thanks for any advice!

• Java: how to get mercurial current changeset number for use in program

  - by Rabarberski

  I've recently started using mercurial for version control in a Java project. When I run my program, the input parameters it has used to produce certain a output, are written to a specific file. It would be nice if I could add the current mercurial changeset number (indicating the version of my program) to that output file as well. What would be the easiest way to do so on Windows? I could write a simple Java parser to fetch the output of the first line of the hg log -l 1 command, but perhaps there is an easier way (i.e., less code lines)?

• How can I view javadocs that have been added to a maven repository?

  - by Coderer

  I know I can use maven to pull the javadocs for an artifact (if they've been added), which should come through as a JAR (right?), which I can then unpack and browse. My problem is, I'm trying to figure out which of a series of artifacts have the particular package I'm hunting for. I could download a half-dozen javadoc packages, unpack all of them, then open the index files one at a time, but that sounds like it would be pretty unpleasant. There must be a better way! I noticed that Nexus supports javadoc artifact browsing, but apparently only in the Pro version (which we do not have, and are unlikely to get any time soon). I'd prefer a GUI solution, though I'd settle for a command line answer, provided it's something along the lines of showmethedocs groupId:artifactId [version].

• Tkinter after that survives clock rewinding.

  - by Oren

  I noticed that in my version of Tkinter, the after() call does not survive system clock rewinding. If the after(x, func) was called, and the system clock was rewinded, func will be called only after the clock returned to its time before the rewind + x milliseconds. I assume this is because Tkinter uses the system-clock instead of the "time.clock" (the amount of time that the program is running). I tested it only on windows, and maybe its because I have an old version of Tkinter. I want my App to work on computers that synchronize their clock from the network... Does anyone have a simple solution?

• PHP Fatal error on line number that doesn't exist

  - by alexantd

  Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 523800 bytes) in /Library/WebServer/Documents/XMLDataStore.class.php on line 981 The curious thing about this error is not the memory leak, which would be easy enough to troubleshoot. Rather, it is the fact that XMLDataStore.class.php is only 850 lines long, which I have verified in multiple text editors. This is with the PHP 5.3 bundled with Snow Leopard. I'm not using an opcode cache. Here is my php.ini: allow_url_fopen = Off error_reporting = -1 display_errors = 1 display_startup_errors = 1 date.timezone = 'America/Los_Angeles' output_buffering = Off realpath_cache_size = 0k XMLDataStore.class.php has recently been refactored and it used to be longer than 981 lines. It's almost as if PHP has cached a 2-week-old version and is reading that. I'm positive that the current version at /Library/WebServer/Documents/XMLDataStore.class.php is only 850 lines long, though.

• Generate MySQL data dump in SQL from PHP

  - by Álvaro G. Vicario

  I'm writing a PHP script to generate SQL dumps from my database for version control purposes. It already dumps the data structure by means of running the appropriate SHOW CREATE .... query. Now I want to dump data itself but I'm unsure about the best method. My requirements are: I need a record per row Rows must be sorted by primary key SQL must be valid and exact no matter the data type (integers, strings, binary data...) Dumps should be identical when data has not changed I can detect and run mysqldump as external command but that adds an extra system requirement and I need to parse the output in order to remove headers and footers with dump information I don't need (such as server version or dump date). I'd love to keep my script as simple as I can so it can be hold in an standalone file. What are my alternatives?

• (Windows Installer) What are some causes for different versions of a program showing 2 entries in ad

  - by Davy8

  Somehow we ended up with something going wrong with one of our recently deployed upgrades (internal deploy, only about a dozen machines or so) and there are now 2 entries for our program showing up in windows add/remove program and I'm trying to figure out what could have caused this. In a nutshell what does windows use to determine whether a program is replacing a previous version or if it's a new program? We are using WiX to create our installers, but nothing in the SVN revisions shows much out of the ordinary (been working fine for the past year with over 100 upgrades). Product version is * because we're forcing a major upgrade each time, but the upgrade code has never changed.

• Building Admin Areas in Rails - General Questions

  - by Carb

  What is the typical format/structure for creating an administrative area in a Rails application? Specifically I am stumped in the vicinity of these topics: How do you deal with situations where a model's resources are available to both the public and the Admin? i.e. A User model where anyone can create users, login, etc but only the admin can view users, delete/update them, etc. What is the proper convention for routing? How does one structure controllers? Are duplicate controllers considered OK? i.e. An admin version and the non-admin version? Thank you!

• On Mac OS X, do you use the shipped python or your own?

  - by The MYYN

  On Tiger, I used a custom python installation to evaluate newer versions and I did not have any problems with that*. Now Snow Leopard is a little more up-to-date and by default ships with $ ls /System/Library/Frameworks/Python.framework/Versions/ 2.3 2.5 2.6 @Current What could be considered best practice? Using the python shipped with Mac OS X or a custom compiled version in, say $HOME. Are there any advantages/disadvantages using the one option over the other? My setup was fairly simple so far and looked like this: Custom compiled Python in $HOME and a $PATH that would look into $HOME/bin first, and subsequently would use my private Python version. Also $PYTHONPATH pointed to this local installation. This way, I did not need to sudo–install packages - virtualenv took care of the rest.

• What's the best way to build software that doesn't require the newest glibc?

  - by ZorbaTHut

  I'm attempting to build a binary package that can be run on multiple Linux distributions. It's currently built on Ubuntu 10.04, but it fails on Ubuntu 8.04 with the following error: ./test: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ./test) ./test: /usr/lib/libstdc.so.6: version `GLIBC_2.11' not found (required by ./test) What's the preferred way to solve this problem? Is there a way to install an old glibc on a new box and build against it, or do I have to build on an old distribution? And if I build against an old glibc, will it work on a new glibc? Or, alternatively, are there just some handy compiler flags or packages I could install to solve the problem?

• How do I conditionally assign ruby variables to javascript variables?

  - by Tony

  I have a website where I need a javascript version of the "current user" object along with the ruby version. I have been assigning these variables doing something like this... Application Controller: def get_user begin @current_user = User.find(session[:user_id]) if session[:user_id] @current_user_json = @current_user.to_json rescue session.delete(:user_id) @current_user = nil @current_user_json = {} end end Web Page: var current_user = null; current_user_json = '<%= @current_user_json %>'; if(current_user_json != ''){ current_user = current_user_json.user; } Even when there is a current user, I get the current user is undefined. Probably because I am putting the current_user_json assignment around single quotes. However, if I don't put it around single quotes, I'll always get a javascript error when no user is logged in because the syntax is invalid - current_user_json = ; I think I am just looking at this completely wrong and there must be a better way. Given that this is probably a common thing to do, I wanted to get other people's opinion on how to create an object in javascript that is a duplicate of the ruby object.

• Does Google appengine cache external requests?

  - by Andy Hume

  I have a very simple application running on appengine that requests a web page every five minutes and parses for a specific piece of data. Everything works fine except that the response I get back from the external request (using urllib2) doesn't reflect the latest changes to the page. Sometimes it takes a few minutes to get the latest, sometimes over an hour. Is there a transparent layer of caching that appengine puts in place? Or is there something else I am missing here? I've looked at the caching headers of the requested page and there is no Expires or LastModified's sent. Update: Sometimes, it will get the new version of the page for a number of requests and then randomly later get an old out of date version.

• How do I propagate an exception thrown by croak in forked child to parent/foreground process?

  - by Pedro Silva

  Throwing an exception via croak in a forked child process seems to print the error as a background process would. That is, it clobbers the shell prompt. If I die instead of croak, the the error message pops up as a foreground process. I've trying to find out why that is in the Carp documentation without any luck. Here's what I mean. The croak version: $ perl Wrapper.pm $ error: ... does not exist at Wrapper.pm line 624 The die version: $ perl Wrapper.pm error: ... does not exist at Wrapper.pm line 515. I tried trapping the fork and printing $@ to STDERR and exiting, but that didn't have an effect. Any ideas? I'd like to be able to use croak in this particular case.

• MySQL update query, how to skip empty values?

  - by Pawel

  I've got such query: $sql = "UPDATE test_accs SET acc_owner = '$owner_id', acc_policy_version = '$version', acc_policy_last_update = '$approved', acc_policy_next_update = '$renewed' WHERE acc_id = '1'"; Now, all of these values on the web folmular are optional, one can set one of these values, two, or so. Now, after I submit the form, it goes in the query like that: UPDATE test_accs SET acc_owner = '2', acc_policy_version = '1.2', acc_policy_last_update = '2012-12-19', acc_policy_next_update = '2012-12-18' WHERE acc_id = '1' It works only when I submit all values from the form. Can you please show me how could it work even if not all the values has been sent, just for example one of them? When I set one value (f.ex. policy version), it looks like that: UPDATE test_accs SET acc_owner = '', acc_policy_version = '1.2', acc_policy_last_update = '', acc_policy_next_update = '' WHERE acc_id = '1' and it isn't working. It might be possible cause of the acc_owner table values? #1366 - Incorrect integer value: '' for column 'acc_owner' at row 1 Thanks in advice.
