PM Software Stack Changelog 2011-2014

Update-Step2: Fix incorrect ram allocation when updating user .rtorrent.rc
Remove check_port plugin which has not functioned correctly in a long time now
hddquota/action.php: Bug fix for incorrect parsing of disk space - oddly enough worked on most cases and bugged only on edge cases. This file is updated on server update
rtorrent communication xmlrpc scgi class basics done - it's actually functional now!
/etc/seedbox/runtime/trafficLimits dir added
addUser.php now saves traffic limit in *GB* to the aforementioned directory
util/userTrafficLimit.php made to match
cron/trafficLimits.php matched and functional. Slight refactoring as well and commenting
cron/trafficLimits.php: Accounts for normal 20Mbps accounts and limits these to 5Mbps.
cron/trafficLimits.php: Removal of limiter enabled so user returns to normal quicker
update-step2: Now also executes setupRootCron - this is the first time in a REALLY long time that the crons gets updated :O
/etc/seedbox/config/root.cron : Now includes traffic limit.

7/11/2014

Welcome page now displays bonus disk space if information is available. Takes a while as the data is rolled out.
Welcome page title now as well vendor name.

20/09/2014

new rtorrentTemplate file for setting port range
rtorrentConfig now sets port range to single port
dht and scgi port ranges changed

13/09/2014

Another rTorrent update, there was a regression on thread names, this is now fixed
rtorrent config: Bumped for larger range of possible scgi ports for rtorrent
Added dhtPort variable for lib rtorrentConfig.
New rtorrent config template file, added the new config variable, max uploads global into the template, and increased range of ports
Changed allocations for less upload slots per unit of ram, since RAM amounts have quadrupled since originally setting this while disk speeds are practically the same.
lib/rtorrentConfig: Added readConfig and readUserConfig methods
lib/rtorrentConfig: Updated headers, version, copyright.
lib/rtorrentXmlrpc: Beginnings of rtorrent communication lib
rtorrent compile: changed this to happen in /tmp, there is a regression where trying to compile libtorrent elsewhere will fail, probably rtorrent too!
new rtorrent version is based on the last one, with few select updates manually applied
install.sh changed to reflect the updated version
lib/rtorrentConfig: Order of setting variables was incorrect, leading to a configuration bug which would lead to rTorrent not starting
util/update-step2: Removed old .rtorrent.rc updates (umask etc. related, very deprecated), and added new configure update based on the readConfig (scgi port won't change etc.!). However with local template it's likely no practical changes happen.
Added new callback data: User traffic data over the past month

06/09/2014

Added first piece of callback data for new management system, diskUsage under util/remote

31/08/2014

Minor revisions to install.sh and code cleanup
Update to latest rTorrent, 0.9.4/0.13.4

12/06/2014

terminateUser.php: added groupdel as well for the user group

09/06/2014

Slight refactoring of terminateUser.php
terminateUser.php: --confirm now first, before username

02/06/2014

Update on versioning issue with installing libmediainfo, mediainfo and libzen. fixed and these will be now installed on wheezy as well.
libdigest-sha1-perl pkg doesn't exist on wheezy so it was preventing several other packages from installing
libdigest-sha-perl pkg now installed on wheezy

11/02/2014

Styling of info tab, info.php/stats.php

29/01/2014

pulsedBox upload: Fixed for new style urls, should work with both subdomain and subfolder setups now.
Installer package updates so that PMSS should install into Debian 7 without a hitch now, previously 2 packages were missing.

Changes 2013

21/12/2013

userTransfer.php: Tries to retry 20 times with 15-120sec delay. Necessary since OVH has introduced new bw limitations: Connections are cut at random, exact rules unknown but result is that transferring user data connections are cut at random. This has been tested via multiple DCs to be true, from multiple OVH DCs.
userTransfer.php: At the end display user's old server password IN CASE the 20 retries is not sufficient.

03/10/2013

install.sh: updated libxmlrpc URI to the new one.

29/9/2013

update-step2: Added wheezy repos
update-step2: Made wheezy repo update
update-step2: Some refactoring in regards of repo updates
cron/trafficLog: Updated traffic parsing to support wheezy
install.sh: Moved apt-get install rar unrar to it's own command due to OVH wheezy template issues
install.sh: Removed some commented out things, blast from past type of things
install.sh: Updated queue read ahead to double size
install.sh: Updated header comments

18/5/2013

install.sh: moving around php5 installation due to continuing OVH template issues

13/5/2013

install.sh: looks like the OVH Debian 6 wants to install apache2 with php5-geoip, so moved around the php5 modules and after their installation remove apache2
install.sh: Added code for removing OVH installed Apache2 which is quite hard to get fully removed, and causes PMSS installation to fail

11/5/2013

update-step2: Added packages required for autodl irssi
update-step2: Added creation of /etc/autodl.cfg

8/5/2013

trafficStats month data traffic is now for the past month, not since beginning of calendar month.
addUser: fixed typo (use of undefined constant)
addUser: fixed argv optionals checking
userConfig: added several checks for user existing
created userTrafficLimit under utils to set the traffic limit
addUser: fixed typo in pathname for traffic limit data
userConfig: added setting traffic limit
userConfig: now restarts rTorrent (near instant)
created trafficLimits cron which checks traffic limits. Communications module is still required before traffic limits can be enabled
update-step2: added smartmontools to pkgs to be installed

20/4/2013

trafficStats now parses 23k lines before 1st of August, 2013 because the traffic logging speed has been lowered at 17th April update -> showing just 1½ weeks initially. Time limit for that so it will not slow down always.

17/4/2013

Added lib/traffic.php for trafficStatistics class
Refactoring showTraffic
stats.php shows this traffic data on info page now
Added cron/trafficStatistics.php which saves traffic data to .trafficData periodically (once per hour)
Decreased traffic data saving to once per 5 minutes
Also now monitoring since beginning of the month
showTraffic now uses the "cached" data saved by trafficStatistics
util/userTransfer.php now puts in request for rTorrent restart after transfer is complete
addUser optional argument for traffic limit in TBs
update-step2 now checks, creates and chmods a bunch of required directories

13/1/2013

Added new remote calls to serverApi, had forgotten this
Dropped traffic logging to 4 min intervals, unfortunately this means showTraffic for 15mins is totally skewed, and maybe noticeable skew on the hourly
updateQuotas cron now every second minute
checkInstances now every 10mins from 15mins, making faster 2nd level redundancy for rTorrent
changed updateQuota cron's API calls to base the call time to modify time of /scripts ie. roughly time the system was installed. This way the requests don't get pooled up at same minute from all servers

12/1/2013

Release of 10th of Jan features as well. Several bug fixes in this release.

showTraffic now prunes erroneous data from the log
trafficLog cron now checks for erroneous data and logs it
updateQuotas sends the user quota and df data only once per hour
Absolute path to iptables on setupNetwork + makeMonitoringRules so it actually works on boot time :)

10/1/2013

Waiting for release, pending server side support.

updateQuotas now reports user quota to API server as well
updateQuotas reports df to API server
lib/users.php error message when issues with /home
setupNetwork won't try to enact empty ruleset anymore
fileCopy updated help message. This is pretty much useless nowadays in any cas and might be deprecated/removed in future release

9/1/2013

One of the DCs changed debian installation template so fixes for that. Issues with rTorrent compilation, lighttpd etc.

Changes on install.sh package removals (apache2 not getting removed??)
Removed munin installation from install.sh
Added installation of pkg-config make openssl
Fixed on update-step2 rtorrent compilation
Install.sh now executes /scripts/update.php but does not do API key setup, it's done on the update script

5/1/2013

Quick performance related hot-fix, and one performance update.

trafficLog now deletes the traffic log file from tmp, this was causing slowdowns etc.
rTorrent peers better configuration, min from 14 to 6 and max from 21 to 32 per "resource block" (Resource block=250Mb of rTorrent ram). This affects only new accounts, reconfigured and recreated.

2/1/2013

Work on the new API - note this is still largely untested so far

API create jobs dir + chmod added
API function to make calls to server added
API function to create authorization for remote calls added
API make call userTraffic added
trafficLog cron fix users check
trafficLog reports traffic to server
serverApi typos fixed (had not been tested before)
serverApi create dirs bugs fixed
serverApi logger was missing newline and has been added
serverApi some commenting added
fixed timestamp on scriptsInc writeLog
trimming some elements in serverApi which due to unrelated reasons have newline at end

1/1/2013

This update also releases the changes of 7/12/2012 which were postponed due to QA reasons.

Removal of netcat packages in update-step2 and install script
Added count checks for users in makeMonitoringRules and recreate lighttpd rules scripts
Copied some standard packages from update-step2 to install.sh
Removed some apt packages from update-step2 which has been on install.sh for a *Really* long time
Removed some irrelevant apt-get lines from install -> duplication
Added p7zip-full package to update-step2 installation
Fix showtraffic weekly data, was only considering ~2/5ths of the data
ShowTraffic compares now user count, not the string returned in order to determine if there is users setup
More uniform ShowTraffic display output, which is also programmatically easy to parse

Added .irssi/config to user dirs, autojoining to #PulsedMedia on Freenode when irssi is launched
Updated GUI IRC links, Chat tab and Adobe download links, with other small additional information and updates.

During update also update user crontabs. Added to both update.php and step2, to be removed from step2 after this update has seen significant adoption.
Restarting lighttpd during update, also done doubly for now
Moved setup api key to regular update script. In several months it will potentially be removed from update all together as it's a installation step, and included to update older nodes.
Scripts permissions update
updateQuotas.php -> cron to update all user quotas, as discreet user from central cron to ensure it gets updated.
Updated root & user crontabs to reflect updateQuotas

28/11/2011

quotaFix now removes aquota*new files to avoid collision and thus failed update via quotacheck
userTorrents.php : Lists the count of torrents each user has, for quicker analysis usage stats

Suspend and Unsuspend scripts fixed
recreateLighttpd backup fixed
Added access format of: servername/user-username/, for example: localhost/user-johndoe/. Thus supporting non FQDN setups
addUser.php calls recreateLighttpd instead of just adding the hostname, this ensures lighttpd config is always up-to-date.
Added to both update steps recreateLighttpd. It will remain on step2 for the next ~6months to ensure every system out there will have the update update.php
Removed the default "testing" torrents
Upload slots global, by default 6 times the non-global upload slots. It is "forcefully" inserted even if template does not it have for the moment. this forcefull insert will be removed in the future.
checkInstances now also checks rtorrent configs, and if changed lists them on /root/changedConfigs for admin review

25/8/2011

Streamlined installer for faster setups :) First release of API, just one command now. Some things moved to BETA status and considered feature complete. Many bug fixes, additional commenting etc. also added

fixed userTransfer chowning lacking -R, thus UID was transferred for many files from the other server causing incorrect permissions
wrapped vnstat install into if !file_exists to see if vnstat is installed already.
added username 'srvadmin' to filter list on systemUsers
removed from installer editing munin.conf -> if used can be done manually. Interim solution.
put install vim as first thing on installer
setting node hostname straight after installing vim
moved setting up lighttpd as last thing
scripts, skel, etc are installed earlier in installation
SSL cert + quota as last items on setup
Executing update-step2 on installer (so you don't need to execute updater after setup to get everything in)
/scripts/util/setupRootCron.php -> creating root conf moved out of update.php
setupSkelPermissions.php, same reason as root cron setup
added setupRootCron and setupSkelPermissions to installer
Idempotent lighttpd configurator feature completed. Backups the config first.
Terminate user moved to beta status, as using lighttpd configurator now and restarting lighttpd.
Added for terminate second argument, if 2nd argument is --confirm, straight accepts termination without asking for approval, for making automation easier.
checkHttpd timer increased to 3 seconds before restarting lighttpd
terminateUser timer increased to 5 seconds after trying to kill all user processes
setupApiKey -> creates node key for API. Invoked upon setup.
added authorization key
removed /var/www/index.lighttpd.html
added /var/www/index.php redir to pulsedmedia.com
added beginnings of remote API for easier remote control management, by default in debug mode for now

8/6/2011

Bug fixes.

terminateUser.php:

Was not actually completing shell userdeletion
Added killing user processes (forgotten)
added sleeping 2 seconds to allow time for rTorrent/other processes by user to die
Added 2nd attempt to userdel after data removal
Fixed some typos in texts
Added check for user actually exists

NOTE: Still Alpha, non feature complete and not recommended for production use.

checkHttpd.php added sleep between lighttpd kill and restart, to avoid PID file mismatch scenario

update-step2.php:

First time being used
update.php moved cron & ftp config stuff AFTER step2
Install vnstat + vim (vim not by default on Debian 6)
Setup interface for vnstat
Configure vnstat for Debian 6
Make vnstat cron jobs for Debian 5: twice a minute update (thus no support for 1GigE interface)
Debian 5 add cron jobs to root.cron.additional config, create if needed

31/5/2011

GUI welcome page checking if proper quota information was passed has been added.
GUI welcome page malformed serialized data fix
GUI welcome page quota percentage missing % char

Users default quota information update rate has been increased to 10mins
HDD Quota plugin commenting added
HDD Quota plugin parser bug with bursted amounts fixed
HDD Quota now shows USED/QUOTA instead of FREE/QUOTA. Makes more sense.
HDD Quota "title" fixed (showing quota info) to be whole area of the meter
Welcome page quota meter added :) Basic graph, larger and constantly visible text for quota info :)
Basic idempotent lighttpd configurator (alpha, not suitable for production, TESTING only)

23/5/2011

terminateUser.php http password deletion fix, text fixes, executability.
checkHttpd.php output lighttpd output, killall -9 lighttpd to ensure shutdown, http fetch mute removed so error gets logged
update.php: removed apt updates because soft.sh already does this
crons: increased check http to 4 minute intervals (avoid http timeout period issues)

18/5/2011

Temporary fix to bypass userDb until fully utilized. You may use this update or use /scripts/util/populateUserDb.php to fix the issue.

Changed listUsers.php to always use systemUsers.php, as fixing userDb saving introduced a bug where ie. checkInstances was not working fully (using userDb, which lacks most users in most servers)

16/5/2011

Few bug fixes and minor features introduced.

Update script order of items.
Update script apt-get options for additional package installation lacked auto confirm.
Update script support for "step 2", /scripts/util/update-step2.php is included if present, thus supporting dynamic updates
Update script execute binary line added, so it can actually be executed simply by ./update.php
/scripts permission fix, only root should have anykind of access (no execute or read for others)
Support for root additional items via /etc/seedbox/config/root.cron.additional
Add user script minor cleanup, additional commenting.
