  • How safe is apache Commons-javaflow while using jasperreports

    - by Nayn
    Hi, I am using jasperreport and trying to pass an alternate report runner. • net.sf.jasperreports.engine.fill.JRThreadSubreportRunner: The initial thread-based implementation • net.sf.jasperreports.engine.fill.JRContinuationSubreportRunner: A Javaflow-based implementation I am using the second one (for the reason, it runs on tomcat server, and creating threads wouldn't be good while writing subreports). The second one depends on commons-javaflow which is a sandbox version. Not sure if I should use it, Could somebody suggest a better way. Thanks

  • Rails3 and safe nl2br !

    - by arkannia
    Hi, I have a system for the users to be able to post comments. The comments are grasped into a textarea. My problem is to format the comments with br tag to replace \n In fact, i could do something like that s.gsub(/\n/, '<br />') But the xss protection including in rails escapes br tags. So i could do this s.gsub(/\n/, '<br />').html_safe But then, all the tags are accepted even script.... causing a big security problem So my question is : how to format text with br safely ? Thanks EDIT: For now, i have add this def sanitaze self.gsub(/(<.*?>)/, '') end def nl2br self.sanitaze.gsub(/\n/, '<br />').html_safe end

  • Creating a unique URL safe hash

    - by Ben Foster
    I want to hash/encode a unique integer (database ID) to create a similarly unique string. It needs to meet the following requirements: Must start with a letter or number, and can contain only letters and numbers. All letters in a container name must be lowercase. Must be from 3 through 63 characters long (although the shorter the better) The result does not need to be reversible, just repeatable - so a 1-way hash would be fine.

  • Looking for a wiki-style, standalone, version-control-"safe" documenation package

    - by basszero
    This may sound like it's not a programming related question, but stick with me here... My team and I have found that documenting our project (a development platform w/ API) with a wiki is both useful to us and useful to the users. Due to some organizational issues, we're forced to do multi-site development without network connectivity. We've switched to a DVCS (Mercurial) and had great success with this. The wiki documentation proves to be a problem as the central site is setup with MediaWiki. The offsite people have no way to access or edit the wiki. Is there any sort of wiki-style package which doesn't not require a server/database and will be useable in a DVCS environment? Update: Should be open-source and cross-platform

  • Do we really need a safe release macro?

    - by Ian1971
    Quite a lot of people seem to use a macro such as #define SAFE_RELEASE(X) [X release]; X = nil; (myself included). I've been reassessing why I am using it and wanted to canvas some opinion. The purpose (I think) for using this macro is so that if you were to accidentally use your object after releasing it then you won't get a bad access exception because objective-c will quite happily ignore it when the object is nil. It strikes me that this has the potential to mask some obscure bugs. Maybe it would actually be preferable for the program to crash when you try to use X again. That way during testing you can find the issue and improve the code. Does this macro encourage lazy programming? Thoughts?

  • Error safe/correcting resource identifier

    - by Martin
    The receiver is my website, the sender is the same but the medium is noisy, a user. He will read an alphanumeric code of length 6 and later input the same code to identify a resource. A good use for a error correcting code, I thought, and rather than do the research I thought I'd just put the question out there. Or I might be going about it the wrong way, since the situation is rather like sending a perfect dictionary along with every transmission. The requirements on the code are simply: 6 alphanumeric digits, to start with until I run out, anyway. If the user gets it wrong I should still be able to identify the right resource. No resource is preferable to the wrong one. Easy to code or have free libraries for .net Any suggestions?

  • Safe way to support hosting files from asp.net mvc site

    - by ooo
    i have an asp.net-mvc site where users can add content and links and the data gets saved in a database. They now want the ability to upload attachments to pages and i wanted to figure out a few things: I have upload code that will upload files (pdfs, images, etc) but i wanted to see where i should be storing them. should i store them outside the website directory structure ? Is there any file types that i should be concerned with storing. I would basically have a file picker on the front end.

  • PHP/CGI: Portable and safe way to get PATH_INFO

    - by LiraNuna
    I'm seeking a portable way to receive the (handy) $_SERVER['PATH_INFO'] variable. After reading a while, it turns out PATH_INFO is originated from CGI/1.1, and my not always be present in all configuration. What is the best (mostly security-wise) way to get that variable - apart from extracting it manually (security concern).

  • C# type safe and developer friendly list/collection technique

    - by Agile Noob
    I am populating a "Dictionary" with the results of an sp call. The key is the field name and the value is whatever value the sp returns for the field. This is all well and good but I'd like developers to have a predefined list of keys to access this list, for safety and documentation reasons. What I'd like to do is have something like an enum as a key for the dictionary so developers can safely access the list, but still have the ability to access the dictionary with a string key value. I am hoping to have a list of string values that I can access with an enum key AND a string key. Please make sure any suggestions are simple to implement, this is not the kind of thing I'm willing to build a lot of overhead to implement.

  • Emulating a transaction-safe SEQUENCE in MySQL

    - by Michael Pliskin
    We're using MySQL with InnoDB storage engine and transactions a lot, and we've run into a problem: we need a nice way to emulate Oracle's SEQUENCEs in MySQL. The requirements are: - concurrency support - transaction safety - max performance (meaning minimizing locks and deadlocks) We don't care if some of the values won't be used, i.e. gaps in sequence are ok. There is an easy way to archieve that by creating a separate InnoDB table with a counter, however this means it will take part in transaction and will introduce locks and waiting. I am thinking to try a MyISAM table with manual locks, any other ideas or best practices?

  • No clock with FTDIchip FT2232 MPSSE mode

    - by Simi
    Hello, I'm trying to write/read to an extern device connected to a FTDIchip FT2232 MPSSE mode using SPI. I'm using the SPI function given by FTDI for Labview. I'm doing this: Open_Device - Init_Device - Write/Read - Close_Device The problem is that I don't have a clock signal on the scope when I try to read/write. Do you have a solution? Thanks

  • Is HashMap in Java collision safe

    - by changed
    Hi I am developing a parser that needs to put key value pairs in hashmap. But a key can have multiple values which i can do in this way HashMap<String,ArrayList<String>> . But what happens if number of keys are very large and it start matching with other key's hashcode. Will that rewrite previous key's value ? thanks -devSunday

  • File mode for creating+reading+appending+binary

    - by MihaiD
    I need to open a file for reading and writing. If the file is not found, it should be created. It should also be treated as a binary for Windows. Can you tell me the file mode sequence I need to use for this? I tried 'r+ab' but that doesn't create the files if they are not found. Thanks

  • Is this query safe in SQL Server?

    - by xaw
    I have this SQL update query: UPDATE table1 SET table1.field1 = 1 WHERE table1.id NOT IN (SELECT table2.table1id FROM table2); Other portions of the application can add records to table2 which use the field table1id to reference table1. The goal here is to remove records from table1 which aren't referenced by table2. Does SQL Server automatically lock table2 with this kind of query so that a new record can't be added to table2 while executing this query? I've also considered: UPDATE table1 SET field1 = 1 WHERE 0 = (SELECT COUNT(*) FROM table2 WHERE table1.id = table2.table1id); Which seems possibly safer, but much slower (because a SELECT would be called on each row of table1 instead of just one select for the NOT IN)

  • Eclipse Debug Mode disrupting MSSQL Server 2005 Stored Procedure access

    - by Sathish
    We have a strange problem in our team. When a developer is using Eclipse in Debug mode, MS SQL Server 2005 blocks other developers from accessing a stored procedure. Debug session typically involves opening Hibernate session to persist an entity which could be accessing a stored procedure used for Primary key generation. Debugging is done in business logic code and rarely in JDBC stored procedure call. Is there any way to configure MS SQL server or the stored procedure so that other developers are not blocked?

  • Is a safe accumulator really this complicated?

    - by Martin
    I'm trying to write an accumulator that is well behaved given unconstrained inputs. This seems to not be trivial and requires some pretty strict planning. Is it really this hard? int naive_accumulator(unsigned int max, unsigned int *accumulator, unsigned int amount) { if(*accumulator + amount >= max) return 1; // could overflow *accumulator += max; // could overflow return 0; } int safe_accumulator(unsigned int max, unsigned int *accumulator, unsigned int amount) { // if amount >= max, then certainly *accumulator + amount >= max if(amount >= max) { return 1; } // based on the comparison above, max - amount is defined // but *accumulator + amount might not be if(*accumulator >= max - amount) { return 1; } // based on the comparison above, *accumulator + amount is defined // and *accumulator + amount < max *accumulator += amount; return 0; }
