I wanted to try STXXL to find how efficient it is in reading a big data file from the disk.
So i setup the enviornment for using it.
Then i ran this program http://algo2.iti.kit.edu/dementiev/stxxl/tags/1.2.1/algo_2sort__file_8cpp-example.html in VS2010. However the file data was not mapped to the vector_type, in fact it deleted the contents of the file after this statement - vector_type v(&f);
I tried changing from stxxl::file::RDWR to stxxl::file::RDONLY, this time the file content was not deleted, however still the vector_type variable was empty.Request your support to proceed further.
Also, is STXXL used widely in commercial applications?
Best Regards,
Ramki.
You are running a code example from STXXL version 1.2.1, which version have you installed on your system?
Most up-to-date version is "Development 1.4" which comes with many improvements, a comprehensive documentation with a lot of short code examples and runs pretty well - check the official STXXL Website under "Downloads and Documentation". Using version 1.4 is highly recommended.
Please check if your problem still exists on the new "Development 1.4" version. The Installation Process has become much easier - read the Installation and Configuration Part of the Documentation at first.
The official webpage provides a (certainly incomplete) list of Publications,Ongoing and Completed Projects using the STXXL successfully - there is no reason why not using it in an commercial environment.

I know that the 5.0 release note say "After the migration, source syntax-highlighting won't be available on a project until it has been successfully analyzed"
BUT, i can't imagine that there is no way to activate just by running another analysis. In fact, when you have thousands of components (it's our case), you can't plan 4500 analysis just to "restore" a basic but helpful functionality ! And it's more true when you know that the majority of theses components wasn't changed since a time ago... :(
So, please, say me that we can write a little batch or program that will do the job without need to pull all the sources ! I don't know how because i don't' understand this limitation of this upgrade (why sources aren't accessible)
You should trust the release notes. Information required for syntax highlighting is computed during analysis. Note that it also requires the language plugins to support this feature. I suggest to upgrade them to latest versions.
I have an old MSDOS software realized in magic 5.6 with an btrieve 5.10a database, that should be modernized(completely redone using a modern DB).
For this I would love to just get the table structures and some understanding in the structure of the magic program.
But unfortunately I was not able to find any documentation on magic nor was I able to get the structure with column names from the tables(.btr but no ddf files).
Any idea on how to get a step further?
Not enough rep to comment, so I'm forced to post this as an answer.
If you can't get hold of any info regarding the data structure you might try:
A. Download and install a try-out version of a more recent Pervasive version and see if that enables you to read the data. In (still more or less current) server versions like V11 there is a DDF Builder utility, which does what the name implies. However, this is no automatic process, but relies on your ability to link the data shown in the application to the hex values on disk.
B. Try to find a BUTIL.EXE version that works with 5.x Btrieve files, run BUTIL -RECOVER and see what that gets you. You might get to parse the data with scripting tools this way - I've done it in the past on 6.x files, but nothing as old as you are dealing with.
The main issue here is whether you'll be able to find compatible tools for a version that old. But then again, maybe 6.x tools might just work.
I am trying to install LXR tp parse my working folder of linux. In some of the tutorials on the web to set it up, they are trying to use the initdb-mysql script to initialize LXR's database in mysql. Well, I can not find this script in v2.0.0 but I can see it in older versions. Is that one still valid for use with v2.0.0? If not, what script I can use to setup the db for LXR v2.0.0? or if this whole DB thing was dropped how can I proceed?
on a side note: why linux projects always lack the proper documentation?!!!! I can see they have procedure for installing LXR on their own webiste and I believe it is outdated...why not update it?
Thank you!
Don't know if you're still looking for an answer, but here is one for the record.
Creating the DB is part of LXR initialization and is considered an internal step (i.e. not end-user visible). As such, it is allowed to change along the configuration process. This is why it is crucial to follow the procedure adapted to the LXR version.
LXR 2.x is configured with a configuration wizard (scripts/configure-lxr.pl) which takes care of generating the DB structure based on a template (templates/initdb/initdb-*-template.sql). These templates are not directly usable; they must be customized by the wizard to produce an initialization script custom.d/initdb.sh which you must manually launch after the wizard has finished its job.
The whole procedure for a simple case is shown on the LXR site. From the home page, select the installation link for the version you use (note that the procedure for 1.x also applies to 2.x).
For complex cases, download and read the comprehensive user's manual from SourceForge. Once again, select the manual adapted to the LXR version.
These manuals are not outdated since the LXR project has a rule to withhold release until documentation is ready.
This is a probably a really simple fix, but I'm extremely new to RealBasic and I'm having difficulty finding help.
dim objUnZipIt as new RealUnzip
The error I keep getting is :
There is no class with this name: di objUnZipIt as new RealUnzip
I'm attempting to debug something in a language I don't know, and the original developer is long gone. Where can I find the library? Or possibly make a small alteration to get this running?
Thank you very much.
Edit: Ok, digging through the folders I found a RealZip.dll . Any idea how I can import this ?
The RealZip plugin was provided by a third-party developer whose website has been offline for several years. You can still grab the plugin from the Internet Archive's copy of their site.
Extract the .rbx file into the plugins sub-directory of the REALstudio install directory and restart the IDE. Since this plugin is no longer maintained, there may be issues with using it in a modern version of the IDE (the included demo project works, though, with only a deprecation warning unrelated to the plugin.)
There's also a GZip plugin available on SourceForge (similarly unmaintained) and the commercial MonkeyBread Compression plugin which is actively maintained.
I noticed in the Magento Certified Developer Study Guide, under the Database section one of the items mentioned is "Write downgrade (rollback) scripts".
I've done some searching to see whether downgrade scripts are supported and it seems they are not. I found this thread from earlier this year in which it seems they concluded that downgrade scripts weren't supported at that time.
Also, did some searching on google and found this article discussing what appears to be some initial support for rollback scripts in the core.
I also searched under app/code/core/Mage for "rollback" and "downgrade" and pretty much most of what I found was code related to DB transaction rollbacks.
Why would the study guide be talking about this if it's not supported? I must be missing something.
Current versions of Magento have no implementation for rollback database migration scripts, where rollback means identifying that a module version number has decreased and running an appropriate script.
Remember through, you're looking at a study guide, not a manual.
While there's no support for formal rollbacks in the current version of Magento, as a Magento developer you may need to rollback database changes made in a previous module upgrade. I'd be ready for questions that describe that scenario, with answers that test your knowledge of existing Magento functionality.
