apt-got mirror engine / News: Recent posts

Hi there,

finally the fully tested v0.8 got released. A lot of great new features got added!
This also marks the end of my project class here at UC Santa Barbara. Finals are over tomorrow and I will start a one month tour through the US. Therefore I might be offline almost all of the time and not able to answer any questions/support request. Please don't hesitate to report anything though. I will pick up the work after I am home again.... read more

Hi there,

I added basic refreshing mechanisms and a brute force purger.
The refreshing mechanism starts every 24 hours or if you state
/trigger/new_package_lists after your module URL
(eg http://localhost/debian/trigger/new_package_lists\).
The FileCache supports object reusage now and does not cloud
the memory anymore. OutOfMemoryException should not occure
anymore as the FileCache uses WeakReferences now to keep
the objects alive.
Started the hard business of documenting.
pre4 is scheduled to be the last prerelease before hitting 0.8.

A gzip wrapper is now used if gzipped package lists are available, reducing bandwidth requirements and startup time. Some major bugs were fixed, including a problem where new Release files were not fetched from the remote server under some circumstances. The server still does not reload new Release files automatically, but refreshes them on a manual restarted.

After letting you wait that long for the next release I decided to release a preview of 0.8[1]. It has more than 2000 new lines of code. But some of the key features for 0.8 are still missing. But if you restart it every other day you should be golden.

See http://hacktor.fs.uni-bayreuth.de/~dun3/apt-got/sf/html/commit_log.html for a complete commit log.

Some added features:
Release files are found and downloaded on start of the server.
Package lists are verified against md5ums found in Release files binary-i386 lists are downloaded on startup (if not yet present and with the right md5sum)
All other lists are set to pending and are downloaded on request if not already present on disk. if present on disk they are checked against the md5um in Release and redownloaded if necessary.

Version v0.7.2 is the first step to an even higher performing apt-got. It introduces the use of NIO (especially the MMAP feature), while a file is not fully download from the remote server. It dramatically reduces memory and CPU usage and therefore allows even faster delivery to the clients.

Major Bugfix.

StandAloneAptGot v0.7.1 fixes bug #944097 [1].
Please upgrade as soon as possible!

apt-got[1] finally released version 0.7 of the StandAloneAptGot[2].
0.7 is a major feature enhancement. A lot changed under the hood of the downloading part of the DebianMirrorModule.
The situation in 0.6 was: If a file was not downloaded locally yet, all data delivery to the clients had to block until the download from the remote server was finished. This could create major delays (eg in case of kernel images)
NOW every byte that gets downloaded is send to all interested clients concurrently.... read more

Hi Folks,

if you think you know what the StandAloneAptGot is all about - and you are sure, that you know how to configure and run it.
Then you maybe want to dramatically increase delivery speed of already cached files with the help of the Apache mod_mirror module. I wrote the configuration manual for you. ( https://sourceforge.net/docman/display_doc.php?docid=22431&group_id=106784 )

Just a reminder: This includes reconfiguring you Apache webserver - so be sure, you know what you are doing.... read more

I posted an introduction to compiling, configuring and running apt-got. This should be the first document to read. Go to the Docs section of the project.

Cheers,
Tobi

I felt, that the project is getting to an actual release candidate. And I got enough feedback to think that there is an "market" for this project.
