Improvements

ISL Conference Proxy 4.3.0 uses Libs 44116

ISL Conference Proxy

ISL Conference Proxy - Core - Tweak SSL settings to pass extra security tests (SECURITY) [ISLCONFPROXY-373] More

Description
Default SSL setting on ISL Conference Proxy have been changed in order to improve security.

ISL Conference Proxy - Core - Update OpenSSL to 1.0.2h (SECURITY) [ISLCONFPROXY-1042] More

Description
Updated internal OpenSSL library to latest version 1.0.2h due to security reasons.

ISL Conference Proxy - Core - Remove support for Windows 2003 (SPECIAL) [ISLCONFPROXY-1082] More

Description
ISL Conference Proxy no longer supports Windows 2003 operating system. User can install ISL Conference Proxy on Windows Vista or newer.

ISL Conference Proxy - Core / Module PostgreSQL - Cancellable/queryable tasks in web admin for vacuum, reindex, etc. (FEATURE) [ISLCONFPROXY-656] More

Description
ISL Conference Proxy now features a system of tasks in the web administration. The notice for such tasks appears at the top of the page, regardless of the viewed page. There is a new setting for limiting the frequency of updating task statuses, found in "Configuration -> Advanced -> Performance -> Limit GRID task status updates in seconds". The default value is 10 seconds.

Three features were initially implemented to take advantage of this task system.

- Reindex PostgreSQL indexes. The problem is that eventually some indexes might get duplicated, leading to database bloat - reindex combats this. The page "Configuration -> PostgreSQL -> Indexes" features a table of indexes, which has now gained a new left-most column, called "Select". It is possible to select which single indexes should be reindexed, or just select all. There is now a button below the table, labeled "Reindex", which triggers the task

- Reindex PostgreSQL tables. Very similar to reindexing indexes. Featured on the page "Configuration -> PostgreSQL -> Tables", with a column to select tables an a "Reindex" button.

- Vacuum PostgreSQL tables. A form of garbage collection in the database for the selected tables. Also featured on "Configuration -> PostgreSQL -> Tables", with its own "Vacuum" button below the table.

ISL Conference Proxy - Core - Create user / must change password on first login is awkward (FEATURE) [ISLCONFPROXY-751] More

Description
Added support for changing password when in user management the field "User must change password" is set to yes.

ISL Conference Proxy - Core - Add initial implementation of multifactor authentication to web pages (FEATURE) [ISLCONFPROXY-752] More

Description
Added initial implementation of multifactor authentication to web pages. This can be enabled in Security / External dialog authenticator. Users must set path to script and this script will be used on login page.

Example multifactor authentication script:

use strict;

use utf8;

use IO::File;

use JSON;

use HTML::Entities;

my %params = ();

for(my $i = 1; $i < scalar(@ARGV); $i += 2) {

$params{$ARGV[$i-1]} = $ARGV[$i];

}

my $step = $params{'arg_step'};

if($step eq 'login') {

print encode_json({redirect_system=>{args=>{username=>$params{'arg_username'}, password=>$params{'arg_password'}, login=>1}}});

} elsif ($step eq 'btn_cont') {

print encode_json({challenge=>{interface=>[

{type=>'hidden', name=>'step', value=>'login'},

{type=>'hidden', name=>'username', value=>$params{'arg_username'}},

{type=>'title', text=>"Login for user: " . $params{'arg_username'}},

{type=>'input', style=>"password", name=>'password', description=>"Enter password for " . $params{'arg_username'}},

{type=>'buttonrow', buttons=>[

{name=>'next', text=>'Login'}

]}

]}

});

} else {

print encode_json({challenge=>{interface=>[

{type=>'hidden', name=>'step', value=>'btn_cont'},

{type=>'title', text=>"Login"},

{type=>'input', description=>'Your username:', name=>'username', value=>$params{'arg_username'}},

{type=>'buttonrow', buttons=>[

{name=>'btn2', text=>'Proceed to next step'}

]}

]}});

}

ISL Conference Proxy - Core - Increase the number of accepted TCP connections from current 100k to 200k (FEATURE) [ISLCONFPROXY-772] More

Description
The number of concurrent TCP connections that ISL Conference Proxy can accept has been raised from 100000 to 200000.

ISL Conference Proxy - Core / Module DNS - Add single address GRID support to configuration page (FEATURE) [ISLCONFPROXY-781] More

Description
ISL Conference Proxy now includes support for single address GRID. There are multiple new settings to configure this.

Automatic name servers:

- "DNS Server -> Zones -> <zone ID> -> Enable automatic name servers" - generates necessary NS records.

- "DNS Server -> Zones -> <zone ID> -> Direct mapping of ids" - directly maps server IDs to NS IDs.

- "DNS Server -> Settings -> Member of automatic DNS server set", default is "Yes" - whether the server should participate in the automatic name server generation.

Single address load balancing is also supported. In can be enabled in "DNS Server -> Zones -> <zone ID> -> Enable load balancing -> Single public address with default service". There are basically two modes of single address load balancing, explained on zone example.com:

# All traffic goes through example.com, even HTTP tunnels through reverse proxies (\-0\-.example.com, \-1\-.example.com, etc.). This mode is enabled when load balancing, "Primary zone for load balancing", and the new "Single public address with default service" are enabled. In this mode, the DNS server will automatically enable the single address feature, which overrides the setting "Configuration -> Security -> Use single public address in GRID".

# All traffic except HTTP tunnels goes through example.com. HTTP tunnels go through server0-\*.example.com, server1-\*.example.com, etc. This mode needs to have the same settings enabled as mode 1, but it additionally requires "Enable GRID server names" and "Primary zone for GRID server names". This mode is recommended, because it improves connection speed and compatibility.

Additionally, the setting "Configuration -> Security -> Do not use service public addresses for web pages" is now by default set to "Yes", while "No" is considered deprecated. The default forces websites to have GRID addresses prefixed with "www.".

ISL Conference Proxy - Core - Record debug info history (FEATURE) [ISLCONFPROXY-782] More

Description
Instead of one file with debug information, located at "[ISL Conference Proxy install]/debug_info/current_debug_info", the folder "[ISL Conference Proxy install]/debug_info/" now contains multiple files, named "debug_info.X", where X is a number. A lower X indicates a more recent file, with "debug_info.0" being the latest file.

ISL Conference Proxy - Core - Add API to access generated .exe files directly in modules (FEATURE) [ISLCONFPROXY-789] More

Description
Database API now includes support to access generated executable files directly from modules.

ISL Conference Proxy - Core - Add data_queue_read_last to db api (FEATURE) [ISLCONFPROXY-793] More

Description
The API for reading and writing the database was updated to version 9.

The changes include:

- Removal of functions, previously declared as deprecated.

- Removal of function data_queue_read_first. The function was usually used as argument "tid" to queue_read_from. The value of this argument should now be an empty string.

- Additional flags (supported by queue_read_from):

-- ISLDB_DATA_QUEUE_FLAG_DESCENDING

-- ISLDB_DATA_QUEUE_FLAG_GREATER_THAN

- The modules that use this API were updated accordingly.

- New tests for checking the updated functions and flags.

ISL Conference Proxy - Core - Linux core file pack/unpack utils (FEATURE) [ISLCONFPROXY-810] More

Description
Added utility script to ISL Conference Proxy installation folder on Linux platform for creating a self contained crash report package with all needed information. Name of this script is pack_core.sh.

ISL Conference Proxy - Core - Implement throttled SWAL (simple WAL) (FEATURE) [ISLCONFPROXY-816] More

Description
In addition to the Write-Ahead Log (WAL) ISL Conference Proxy now adds the option of a Simple WAL (SWAL). There are multiple reasons for choosing SWAL over WAL:

- WAL replay puts a very high load on the DT server because of many writes to the database.

- WAL uses global locking, which tends to drop GRID connections if employed for long periods of time (because of the abovementioned performance issues).

- WAL does support snapshotting as opposed to SWAL, but DT does not, so this potential advantage does not come into play.

- SWAL runs in a separate thread without global locking.

- SWAL is implemented as part of DT GRID backend instead of frontend, further improving performance.

- There is no need to run SWAL replays between DT servers, because DT async already takes care of that.

- SWAL replays are delayed until DT async is done.

- SWAL requires just a single WAL round-robin file instead of one per server, which speeds up startup.

SWAL can be enabled in "Manage Software -> Features -> Database replication method", where there are two new options:

- "Simple write-ahead log and HexHash (swal+hhash)"

- "Simple write-ahead log (swal)"

There are multiple new settings regarding SWAL, found in "GRID -> Settings":

- "Remote buffer database log size (MB)", default 500.

- "Remote buffer database log location cache", default 1000.

- "Database log replay max age in seconds", default 2592000 (exactly 30 days).

- "Direct tables sync blocks SWAL replay", default "Yes".

- "SWAL receiver is considered backlogged in seconds", default 120s.

- "SWAL receiver backlogged penalty", default 10000.

ISL Conference Proxy - Core - Turn off TCP keepalive (FEATURE) [ISLCONFPROXY-822] More

Description
In order to reduce the CPU, memory, and bandwidth load on the ISL Conference Proxy server, TCP keepalive has been turned off.

ISL Conference Proxy - Core - Add simple replication status report in web admin (FEATURE) [ISLCONFPROXY-824] More

Description
ISL Conference Proxy now reports the GRID replication status on top of the web administration pages. This is done to to communicate the synchronization of servers in a simpler manner. If there are no replication messages, the status is not shown and the servers are synchronized. After the individual message, the number of the server that reported it is also shown.

Currently, the replication status reports about these events:

- "Direct tables" (send/receive)

- "Simple write-ahead log replay" (send/receive/ receive blocked by direct tables)

- "Write-ahead log replay" (send/receive)

- "Write-ahead log snapshot" (send/receive)

- "File storage" (send/receive)

- "Write-ahead log snapshot" (inactive / send, waiting for remote server)

- "HexHash" (send/receive)

There is also a new setting "Configuration -> Advanced -> Performance -> Limit GRID replication status updates in seconds", default is 10 seconds.

ISL Conference Proxy - Core - Limit child_of queries on DT to improve delete objects performance (FEATURE) [ISLCONFPROXY-830] More

Description
When an object is deleted from a database table, it also needs to check other tables for possible child objects. However, this is mostly done for legacy reasons, as there aren't very many parent-child relationships in the database, and it mostly just slows down the database. In order to optimize performance, the API gained the option to register "child_of" relationships (and modules were updated accordingly), which serve to signal a check for child objects, while object without this relationship don't perform the check anymore.

ISL Conference Proxy - Core - Remove HEFA_LOCK locks from bulk file operations, other optimizations (FEATURE) [ISLCONFPROXY-838] More

Description
Many changes have been implemented in order to optimize the performance of the bulk file operations. The major optimizations are:

- Optimized read/write locks when reading files.

- Bulk file upload and download are now parallel tasks.

- Detailed timing of downloads.

- Simplified consistency checking.

ISL Conference Proxy - Core - Disable indirect customizations by default (FEATURE) [ISLCONFPROXY-843] More

Description
Added a new option: "Configuration -> Advanced -> Performance -> Enable indirect customization IDs". The default value is set to "No", which should reduce the cache pressure of the packet generator.

ISL Conference Proxy - Core - Add features to DT converter to support ISL Groop module (FEATURE) [ISLCONFPROXY-847] More

Description
Direct tables converter now supports converting ISL Groop module old database format to direct tabeles format.

ISL Conference Proxy - Core - Start using escape_xml for better XML compliance (FEATURE) [ISLCONFPROXY-848] More

Description
Better XML compliance is provided as in several places HTML escaping was replaced with XML escaping due to stricter and safer checking, introducing some unicode filtering.

ISL Conference Proxy - Core - Data file content dumper in debug menu (FEATURE) [ISLCONFPROXY-850] More

Description
A new option has been added to the "Debug" menu to dump contents of a database table into a file, using a drop-down list of tables and a button "Dump table content". As opposed to a raw dump, this makes VFS and DT data easier to compare. Clicking the button creates a file named "dump_table_content_<table name>.<id>" in the ISL Conference Proxy installation directory, where <id> is a number beginning with 0 that increases if multiple content dumps of the same table have been made.

Additionally, in "Configuration -> Advanced -> Raw data -> Utility links", "Download object from" has been renamed to "Download object", and it contains a new link "content", which dumps the database content of the server configuration (but not into the ISL Conference Proxy installation directory), with a name like "s-999_0_0.bin".

ISL Conference Proxy - Core - Remove bulk_connection lock, fetch connections from pool (dt or vfs query) (FEATURE) [ISLCONFPROXY-852] More

Description
It is now possible to bulk delete files only on the observed server instead of on all servers in the GRID. The option can be found in "Configuration -> Advanced -> Bulk files", where along the "Delete selected" button there is now also a "Delete selected locally" button. Additionally, some performance optimizations have been implemented, such as removing the lock from these bulk connections and fetching them from a connections pool.

ISL Conference Proxy - Core - Add (S)WAL log stats tool (FEATURE) [ISLCONFPROXY-854] More

Description
ISL Conference Proxy now contains a tool for observing the Write-Ahead Log (WAL) statistics - it also works with the new SWAL.

Usage: confproxy_server --wal-tool <flags> <command> <log_file> <state> <count>

- <flags> must be either --wal or --swal.

- <command> must be one of: info, dump, stats. If <command> is info, <state> and <count> should not be provided.

- <log_file> can be e.g. "<ISL Conference Proxy installation>/db/\_\_swal\_\_/log" or "<ISL Conference Proxy installation>/db/\_\_writelog\_\_/log".

- <state> specifies which logged event should be the first to be displayed and <count> specifies how many should be displayed. The "info" command does not require these two arguments - instead, running the "info" command outputs "state=<total number of events>" and "first_state=<index of first event>".

ISL Conference Proxy - Core - Add LB penalty to server with backlogged SWAL receiver queue (FEATURE) [ISLCONFPROXY-856] More

Description
The Simple Write-Ahead Log (SWAL) contains two settings for controlling the backlogging functionality, found in "Configuration -> GRID":

- "SWAL receiver is considered backlogged in seconds", default is 120s.

- "SWAL receiver backlogged penalty", default is 10000.

Using the default settings, if the delay between the file "<ISL Conference Proxy installation>/db/\_\_swal\_\_r" and the database exceeds 120s, that server is considered backlogged; the GRID sets 10000 points of load balancing penalty for that server until the file "\_\_swal\_\_r" is empty again.

ISL Conference Proxy - Core - Add request cache for repetitive packet generator requests (FEATURE) [ISLCONFPROXY-858] More

Description
The packet generator could overload the server by generating many responses for requests that required the same packet. These response are now cached in order to reduce the load on the server.

ISL Conference Proxy - Core - Remove expensive DB reads and HEFA_LOCKs if customization is used in packet generator (FEATURE) [ISLCONFPROXY-861] More

Description
Added a new option: "Configuration -> Advanced -> Performance -> Cache customizations in memory". The default value is set to "Yes", which removes expensive reading and locking of the database.

ISL Conference Proxy - Core - Improve RP logging for internal web server error (FEATURE) [ISLCONFPROXY-862] More

Description
If an internal server error occurs, the error report also includes which server was the source ("source server =") and which the destination ("remote server ="), if those servers are not the same as the one that is handling the error. If the current handling server is the same as the source and the destination, this is also reported ("fully local handler").

ISL Conference Proxy - Core - Expose webcontext serial executor in API (FEATURE) [ISLCONFPROXY-864] More

Description
Webcontext calls handle function in its queued executor. To enable webcontext implementators to use this serial executor, it was exposed in API.

ISL Conference Proxy - Core - Add on_not_found match (FEATURE) [ISLCONFPROXY-867] More

Description
When trying to download ISL Light 4 on Windows XP or Windows Vista (e.g. "icpserver/start/ISLLight"), users would only receive "No software found", because ISL Light 4 is not available on those systems. This has been redesigned so that users should click on a link with added "?on_not_found_name=ISL+Light+Desk", which returns ISL Light Desk, which is available on these systems. The "on_not_found" link handler is also available for other links that would otherwise return "No software found".

ISL Conference Proxy - Core - Make it easier to get debug info from dmp on Windows (FEATURE) [ISLCONFPROXY-877] More

Description
When ISL Conference Proxy crashes, a "\*.dmp" file is created in the ISL Conference Proxy installation directory, e.g. "ISLMini5028confproxy_server.dmp". ISL Conference Proxy now expands this by also generating a "\*.dmp.debug_info" file, e.g. "ISLMini5028confproxy_server.dmp.debug_info".

ISL Conference Proxy - Core / Linux - Import jemalloc for better memory stats (FEATURE) [ISLCONFPROXY-878] More

Description
The Linux version of ISL Conference Proxy now supports the jemalloc memory allocator. To enable it, go to "Manage Software -> Features", section "Memory allocator". It is also possible to provide options to the jemalloc allocator - these options correspond to the MALLOC\_CONF jemalloc variable and are stored in "/var/confproxy/jemalloc.conf". If jemalloc is selected as the allocator, a file named "/var/confproxy/feature_malloc" is created, containing the string "jemmaloc".

ISL Conference Proxy - Core / Linux - Limit system malloc arena count (FEATURE) [ISLCONFPROXY-882] More

Description
ISL Conference Proxy running on Linux could encounter excessive virtual memory usage when using the default memory allocator. One step taken to alleviate this is to limit the number of arenas the default memory allocator is allowed to allocate. By default, this number is equal to the number of cores in the server's CPU, but can be overridden by creating/changing the file "/var/confproxy/sysmalloc_arena_max" and setting its contents to the maximum number of allowed allocatable arenas.

ISL Conference Proxy - Add logging subsystem for license functions logging (FEATURE) [ISLCONFPROXY-885] More

Description
An option has been added to log the output of license functions, found under "Configuration -> Logs -> Subsystem license debug log".

ISL Conference Proxy - Core - Optimize log line filtering (FEATURE) [ISLCONFPROXY-886] More

Description
In order to reduce memory leaks, two optimizations pertaining to log filtering have been implemented:

- Log filtering is done immediately instead of in the separate thread, responsible for actually dumping the log.

- Log filtering now uses static instead of dynamic memory allocation.

ISL Conference Proxy - Core / Linux - Memory allocation spectrum (FEATURE) [ISLCONFPROXY-887] More

Description
The Linux version of ISL Conference Proxy now supports the mallocspectrum memory allocator. The main feature of mallocspectrum is the ability to log the allocations. To enable it, go to "Manage Software -> Features", section "Memory allocator". If enabled, a file named "feature_malloc" is created in the "/var/confproxy" folder. Allocation is logged into the file "mallocspectrum.<pid>.log", where <pid> denotes the process ID of the running ISL Conference Proxy server.

There are two main options:

- "Log interval on total allocation increase of 2^n bytes" - An unsigned integer _n_, which signifies how much does the total allocation size have to increase in order for the values to be logged. The default _n_ is 20, which means that memory allocation will be logged whenever total allocation increases by 2^20 bytes (1MB). If a value is set, a file named "mallocspectrum_loginterval" is created.

- "Track stacks" - A toggle switch to enable/disable stack tracking and logging. An additional option specifies the initial configuration - if set, a file named "mallocspectrum_trackstacks" is created.

On the "Features" page there is also a link next to the mallocspectrum switch that points to "Activity Monitor -> Mallocspectrum". From there, the track stacks configuration can be changed, or the current allocation state can be logged by clicking on the "Record total state" button.

The raw log file can also be converted into a CSV file with the help of the "mallocspectrum2csv.pl" tool, which is provided in "/var/confproxy". An example of invocation:

perl mallocspectrum2csv.pl mallocspectrum.20278.log

ISL Conference Proxy - Core - Optimize activity log code when it's off (FEATURE) [ISLCONFPROXY-889] More

Description
Performance improvement: if activity log is not enabled, ISL Conference Proxy doesn't start empty activity log tasks anymore.

ISL Conference Proxy - Core - Add 'no pack' option for Linux core files utils (FEATURE) [ISLCONFPROXY-892] More

Description
The new "/var/confproxy/pack_core.sh" tool includes the option to not actually pack the core dump, but instead create a debug directory. Additionally, the original core dump file does not get deleted. To enable this, add the command line argument "--no-pack" before the core dump file name.

ISL Conference Proxy - Core - Packet generator cache disk writes outside of lock (FEATURE) [ISLCONFPROXY-894] More

Description
There was an issue in ISL Conference Proxy where the packet generator would write to a cache file, but at the same time block all other reads and writes (global lock), leading to long response times. A new approach has been implemented, where a small temporary cache file is created and worked on, while the global lock is employed for a much shorter time to copy from the temporary file to the actual cache file.

ISL Conference Proxy - Add logging of error reports (FEATURE) [ISLCONFPROXY-895] More

Description
Error reports - usually sent to the ISL Conference Proxy system email address - now also get reported to the "confproxy_server.log" file. In the log, error reports are prefixed with "Report:".

ISL Conference Proxy - Add debug action to report error line (FEATURE) [ISLCONFPROXY-896] More

Description
In the "Debug" page ("Configuration -> General -> Show debugging menu" needs to be enabled) there is now a new debug action, "Report Error Line". It consists of two text fields and a button labeled "Report Error Line". Clicking on the button will cause the line to be logged as if it originated from a module, named in the first text field, that logged an error line, represented by the second text field.

ISL Conference Proxy - Core - Add setting to toggle sending of error reports to email (FEATURE) [ISLCONFPROXY-897] More

Description
Added the option to toggle the sending of error report emails, found in "Configuration -> Logs -> Report logged errors to system email address(s)".

ISL Conference Proxy - Core - Join Page - Create new ISL Conference Proxy version of join page, prepare workflow which support also mobile devices (FEATURE) [ISLCONFPROXY-899] More

Description
Join page was completely redesigned and supports mobile devices. If users want to join to the session from mobile device, they will be able to open application (ISL Light or ISL Groop) if application is installed on mobile device, or download application from appropriate store. Join page is also completely responsive and has minimalistic design.

ISL Conference Proxy - Webapi2 - Extend session/query/2 with arguments userAgent make joinLink dependant (FEATURE) [ISLCONFPROXY-903] More

Description
Webapi2 method session/query/2 was introduced. Method accepts two arguments:

- session code ("code")

- user-agent ("userAgent"): <application>(<platform>), e.g. "ISLLight("Win\;)".

Method returns the following fields:

* joinPageURL (join page was redisigned, more info at ISLCONFPROXY-899)

* platformType

* service

* sessionCode

* startProgramButtonCaption

* startProgramURL

* supporterEmail

* supporterName

* supporterUsername

ISL Conference Proxy - Core - Implement html frame v2 according to new CSL customizations best practices (FEATURE) [ISLCONFPROXY-904] More

Description
We have implemented HTML frame v2. On ISL Conference Proxy under web server, users can set "Web template" version like 430 and they will have new look of ISL Conference Proxy page. Users can set this new feature also for join page (Join UI version), login page (Login UI version), forgot password page (Forgot password UI version), etc. Users can also set different "Web template" version for different users under User management / <username> / Web server. New frame v2 version is also responsive, which means that page will adapt to different screens/devices.

ISL Conference Proxy - Add logging subsystem for reports logging (FEATURE) [ISLCONFPROXY-906] More

Description
A new setting has been added to ISL Conference Proxy: "Configuration -> Logs -> Subsystem report debug log", which is enabled by default. It controls whether and how the subsystems are logged - this includes the packet generator, bulk files, and license subsystems. These subsystems normally get logged only if "Log only critical events" is set to "No", but this new setting overrides it and, if enabled, always logs the subsystems. Additionally, if this new setting is enabled, the logged line contains a "*** Report" prefix instead of a "Report" prefix.

ISL Conference Proxy - Core - Add option to disable block allocator cache for netbuf (FEATURE) [ISLCONFPROXY-908] More

Description
It is now possible to enable and disable netbuf counters and cache using the following files, which should be placed in the ISL Conference Proxy installation directory and don't need to contain any content:

- "netbuf_counters" - enables counters.

- "no_netbuf_counters" - disables counters. Overrides "netbuf_counters".

- "netbuf_cache" - enables cache. Overrides "no_netbuf_cache".

- "no_netbuf_cache" - disables cache.

By default, counters are disabled and cache is enabled.

ISL Conference Proxy - Core - Always allow connections to /conf from localhost even if blocked by web access filter (FEATURE) [ISLCONFPROXY-909] More

Description
Connections to "/conf" are now always allowed on localhost, regardless of web access filter settings.

ISL Conference Proxy - Core - Add check to button "Restart server" in /conf/servers (FEATURE) [ISLCONFPROXY-914] More

Description
In order to prevent accidental server restarts, the "Restart selected" button (found under the table of servers in "Activity Monitor -> Servers") now requires a check to the left of the button to enable it before it can be pressed.

ISL Conference Proxy - Core - Better error messages when login cannot be done by email (FEATURE) [ISLCONFPROXY-915] More

Description
In some cases login cannot be performed using an email address, but ISL Conference Proxy marked this kind of attempt simply as a failure. To improve on this, ISL Conference Proxy now reports "Unable to login with user <email>. Please use full username: \\\username or \\domain\username". There are multiple scenarios that this change affects, based on the number of accounts that match the email address:

use HTML::Entities;

my %params = ();

for(my $i = 1; $i < scalar(@ARGV); $i += 2) {

$params{$ARGV[$i-1]} = $ARGV[$i];

}

if(exists $params{'var_user_id'}) {

my $code = $params{'arg_code'}; $code = '' unless defined($code);

my $correctcode = $params{'var_code'}; $correctcode = '' unless defined($correctcode);

if($correctcode eq '') {

$correctcode .= int(rand(10)) for ((0..3));

# send $correctcode to user over secondary channel

IO::File->new('code.txt', 'w')->write($correctcode);

}

my $count = $params{'var_count'}; $count = '0' unless defined($count);

if($code eq $correctcode) {

print encode_json({redirect_system=>{multifactor_done=>1}});

} elsif($count >= 3) {

print encode_json({challenge=>{interface=>[

{type=>'text', style=>'error', text=>'Too many failed attempts'},

{type=>'buttonrow', buttons=>[

{action=>'cancel', text=>'Retry'}

]}

]}});

} else {

print encode_json({challenge=>{setvar=>{code=>$correctcode, count=>$count+1}, interface=>[

$code eq ''

? {type=>'text', style=>'warning', text=>'Code is required for account '.encode_entities($params{'var_name_nice'}).' with email "'.encode_entities($params{'var_key_email'}).'"'}

: {type=>'text', style=>'error', text=>'Incorrect code, please try again'},

{type=>'input', description=>'Enter code:', name=>'code', default=>$code},

This objects hold information about the connection and get distributed to all servers in GRID environment. Single user (user's browser) can open up to 6 connections, it means every user will get 6 of these and all distributed. To not have to many objects this is controlled by only creating those who persist for a certain amount of time. Default value is 20 (in seconds). -1 means disabled, no objects will be created.

ISL Conference Proxy - Core - Sometimes CP reports high time for create packet (DEFECT) [ISLCONFPROXY-301] More

Description
In some cases the packet generator subsystem in ISL Conference Proxy would require a very long time (over 1 minute) to generate a packet, which lead to long waiting times in client applications. This also affected the bulk file subsystem. Multiple steps have been taken to alleviate this:

* Generating packets in chunks is now timed

* The packet generator subsystem and the bulk files subsystem can now be logged. The settings can be enabled in "Configuration -> Logs", where they are exposed under the names "Subsystem packet generator debug log" and "Subsystem bulk files debug log".

* The option to set the cache time limit for the packet generator ("Configuration -> Advanced -> Performance -> Packet generator cache time limit in seconds") has been removed. Instead, the packet cache settings can now change during server runtime.

ISL Conference Proxy - Core - Add limit to size of error and number of errors send to other servers (DEFECT) [ISLCONFPROXY-916] More

Description
ISL Conference Proxy would sometimes report a large number of internal server errors to other servers in the GRID, which could have lead to stability issues. To alleviate the issue, multiple user-controllable restrictions on the length and number of errors have been set.

In "Configuration -> Advanced -> Web server":

- "Internal error max length", default is 2048. Maximum length of an internal error message, including the automatic "Module \[module name\]: " prefix.

- "Save max internal errors locally", default is 1000. How many internal errors are stored and reported on the local server. If the number of internal servers exceeds this number, the oldest errors get deleted to make room for newer ones.

- "Save max internal errors remotely per server", default is 10. How many internal errors are pushed from the local server to each other remote server in the GRID.

- "Web server internal error l.b. penalty" has been renamed to "Internal error l.b. penalty" to reflect the fact that all internal servers are now handled this way, not only web server internal ones.

There is also a new setting "Configuration -> Advanced -> Performance -> Limit GRID error status updates in seconds" (default 10s), which limits how often the error reports are synchronized between servers in the GRID.

Additionally, in "Activity Monitor -> Servers", the button "Clear web internal error" has been renamed to "Clear internal errors".

To simplify debugging, four new submission forms have been added to the "Debug" menu. Each one has a text field for the reporting module name, a text field for the error message, and a submission button, as listed below:

- "Set internal error" - creates an internal error.

- "Unset internal error" - removes an internal error.

- "Report error" - reports a non-internal error to the system email address. Includes an additional text field "Subject", which is the subject of the email.

- "Remove error" - removes a non-internal error.

This defect was fixed.
