ReGaHss ChangeLog
-----------------
2018-02-27 Jens Maus <mail@jens-maus.de>
* optimized system.Exec() to avoid creating zombie processes in case
background execution using "&" is used.
#### BETA27-2018-01-14 (440f8d6) Release ####################################
2017-12-26 Jens Maus <mail@jens-maus.de>
* added "incorrect use" warnings for use of Device() on DP objects and
LastTimestamp() and LastTimestampSeconds() on channel objects similar to
the already existing warning on incorrect use of AlDestMap().
* added automatic variable stack enlargement which should allow to deal with
way more variables on the script execution stack than before.
2017-12-18 Jens Maus <mail@jens-maus.de>
* added default charset encoding "iso-8859-1" to all xmlrpc responses so
that clients should have additional information to decode xmlrpc responses
correctly.
#### BETA26-2017-12-09 (b3bc9eb) Release ####################################
2017-12-08 Jens Maus <mail@jens-maus.de>
* added minimum of 5k for globally modifying the number of Iterations using
system.MaxIterations(max)
#### BETA25-2017-12-04 (518321a) Release ####################################
2017-12-03 Jens Maus <mail@jens-maus.de>
* added system.MaxIterations(max) method which allows to modify the maximum
number of iterations for while()/foreach() loops. Calling this method
with 0 will result in while()/foreach() to loop indefinitly. Calling it
with -1 will restore the default of 500000 iterations.
* removed all ID_XXXXX_MAX_COUNT entries from the public symbolic constant
table were they didn't belong to.
2017-11-24 Jens Maus <mail@jens-maus.de>
* fixed bug where invalid objects in the shared user object list required
multiple restarts to completly cleanup the list.
#### BETA24-2017-11-14 (7338722) Release ####################################
2017-11-14 Jens Maus <mail@jens-maus.de>
* fixed bug where deleting an object didn't remove it from the shared
user objects list. Also added an automatic cleanup routine upon loading
the regadom which will remove all invalid object ids in the shared user
objects list.
2017-11-09 Jens Maus <mail@jens-maus.de>
* fixed bug where using ToTime() on a time object and Filename() on a xml
object returned incorrect results.
#### BETA23-2017-11-07 (705d243) Release ####################################
2017-11-06 Jens Maus <mail@jens-maus.de>
* fixed more DST related bugs in the time module which could result in
various different issues at DST borders.
2017-11-03 Jens Maus <mail@jens-maus.de>
* modified error output to be more verbose when assigning incompatible
data to a system variable of a different type.
#### BETA22-2017-11-03 (9f7bc6c) Release ####################################
2017-11-01 Jens Maus <mail@jens-maus.de>
* fixed bug where on a DST switching date the internal time module crashed
ReGaHss because internal time calculation routines couldn't deal with
DST borders.
2017-10-11 Jens Maus <mail@jens-maus.de>
* added warning output if the maximum number of iterations for while() and
foreach() use has been reached. This should make it easier to reveal
situations where while()/foreach() uses show strange results because of
the max iteration limitation. Also increased the maximum iterations to
500000 because this also only takes a few seconds to be processed and
shouldn't block the ReGa too long.
#### BETA21-2017-10-01 (469725b) Release ####################################
2017-09-23 Jens Maus <mail@jens-maus.de>
* modified ToString(p) output for floating point values to be limited to the
documented maximum precision of 15 digits. Otherwise an output of a float
with higher precision might lead to some confusion.
* modified floating point comparison epsilon to DBL_EPSILON to be consistent
with the documented floating point precision (15 digits).
2017-09-22 Jens Maus <mail@jens-maus.de>
* modified == and < comparison operators to use an epsilon-based comparison
if applied on a float value comparison. This should make script-based
comparisons compatible to the same way webui-based programs perform their
comparisons.
* modified .Trunc() to output the same truncated float value like
.ToInteger(). Only if Trunc(p) is used with an additional parameter p
the float value will be truncated to the p-th digit based on the
real float value.
* integrated an additional parameter for .ToInteger(p) when being used on
float values. If specified, the truncation operation will be based on
the result of ToString(p) with the precision p.
* modified .ToInteger() to truncate a float value based on the same rounding
operation like .ToString(). This should make uses of x.ToString().ToInteger()
consistent with direct uses of x.ToInteger() again.
* modified ToString() to output floating point values rounded to the sixth
digit again.
2017-09-20 Jens Maus <mail@jens-maus.de>
* fixed bug where ToString(p) on an empty string delivered a wrong output.
* fixed bug where value list and binary-type system variables couldn't be
set from programs anymore.
* fixed bug where char-based system variables couldn't be emptied anymore.
2017-09-16 Jens Maus <mail@jens-maus.de>
* fixed another bug with using elseif() which resulted in ScriptRuntimeError
outputs even thought all conditions where checked and executed correctly.
#### BETA20-2017-09-13 (330c383) Release ####################################
2017-09-11 Jens Maus <mail@jens-maus.de>
* fixed a bug in the web request response generation which supplied invalid
xml formatted data for hm scripts containing string variables with special
characters like '<' or '>'. Now these special characters are properly
escaped so that valid xml data is returned and thus won't result in, e.g.
JSON formatting errors if the script test window is used in the WebUI.
2017-09-10 Jens Maus <mail@jens-maus.de>
* fixed a problen where due to implicit BINRPC definitions in how floating
point values are supplied, some sensors reported slightly inaccurate float
values (e.g. dimmers) resulting in various numeric problems. Now a proper
float point rounding method is applied that maintains float values to be
keep accuracy up to the sixth digit.
2017-09-09 Jens Maus <mail@jens-maus.de>
* fixed a bug in using multiple elseif() statements in a row which resulted
in multiple executions of the alternative branches.
2017-09-08 Jens Maus <mail@jens-maus.de>
* fixed a regression bug which were the reason for "CompatibleForCompare"
errors on programs using dimmer devices in program conditions.
2017-09-07 Jens Maus <mail@jens-maus.de>
* fixed problem that upon changing the value type (integer, float, string)
of ISE values after a program was already created using, e.g. system
variables or devices returning value in a certain type that ReGaHss
aborted program execution by issuing "CompatibleForCompare" errors. Now
it will try to convert to the desired type first and only issue this error
if a conversion is also not possible.
* fixed floating point to string conversion routines (e.g. ToString()) to not
use any floating point rounding but truncate values after the 6th digit
so that output e.g. using WriteLine() is somewhat more consisent and
human comparable to the real values.
2017-09-06 Jens Maus <mail@jens-maus.de>
* fixed inconsistent rounding operations when using ToString(p) with an
optional parameter to specify the precision in case it is used on real
or string variables containing a floating point value.
#### BETA19-2017-08-31 (821f393) Release ####################################
2017-08-31 Jens Maus <mail@jens-maus.de>
* fixed the XmlRpcDataType to variable conversion to always perform an
integer conversion in case the xmlrpc call returns an integer rather
than potentially performing a conversion to byte which might result
in incorrect values in variables.
2017-08-29 Jens Maus <mail@jens-maus.de>
* reworked HTTPServer startup to allow more than 10 parallel HTTP server
worker threads to be running at the same time.
* added all missing "ID_XXXXXX" type identifiers for constant ise id
objects and datapoints. This includes ID_GW_SYSALARM, ID_GW_SYSSERVICE
to retrieve the object id for alarm and service messages.
* reworked system.Exec() to execute the supplied command in the context of
a full shell rather than calling the command directly. This enables
system.Exec() to execute commands with more than 9 arguments and to use
complex shell syntax (such as shell pipes "|", redirections ">" and ";"
to execute more than one command). Furthermore, errors on command
execution should be reported and handled more properly now.
2017-08-26 Jens Maus <mail@jens-maus.de>
* the method .ToString(p) can now also be used on a string-type variable to
round a floating point type string to a specified precision p. If a
string, however, contains non integer/float characters a .ToString(p)
call will just return the unmodified string.
#### BETA18-2017-08-26 (f5fddc6) Release ####################################
2017-08-25 Jens Maus <mail@jens-maus.de>
* implemented "HttpListenerMaxConnections" rega.conf config option to be
able to raise the default number of 6 parallel http connections.
#### BETA17-2017-08-08 (d5ff468) Release ####################################
2017-08-07 Jens Maus <mail@jens-maus.de>
* fixed bug where using escaping control characters strings like "\t"
caused a syntax error if specified as an argument to a method.
2017-08-05 Jens Maus <mail@jens-maus.de>
* renamed all internal "SINGLECOND" identifiert to "SINGLECONDITION" for
consistency reasons.
* added the following missing symbol constants: OT_CALENDARDPS,
OT_INTERFACES, OT_RULE, OT_RULES, OT_SINGLECONDITION, OT_DESTINATION,
OT_SINGLEDESTINATION
* renamed method "RulePRogramID" to "RuleProgramID" to fix typo.
#### BETA16-2017-08-04 (029f1ee) Release ####################################
2017-08-03 Jens Maus <mail@jens-maus.de>
* implemented an "elseif" token which can be used in complex if/else
statements so that code obfuscation can be reduced by using "elseif()"
rather than "else { if() }".
* added new .Replace(s, d) string method which can be used to search
for a substring 's' and replace it with 'd' in a string variable.
2017-08-02 Jens Maus <mail@jens-maus.de>
* added new .StartsWith(s) and .EndsWith(s) string methods which return
true or false depending on the supplied substring.
* added new .Contains(s) method which returns true/false if a string
contains the supplied substring s.
* added new .Trim(c), .LTrim(c) and .RTrim(c) to trim whitespaces
from strings either from left+right, left or just right. By specifying
an optional character string "c" the stripable characters can be
specified.
* added new .ToUpper() and .ToLower() method that allow to convert a
string variable to its uppercase or lowercase representation.
* added new .ToUTF8() and .ToLatin() methods that allow to convert
a string variable to/from UTF8 from/to Latin (ISO-8859-15).
* added new .UriEncode() and .UriDecode() methods that will encode and
decode a string variable to/from a URI conform way (%XX encoding).
2017-08-01 Jens Maus <mail@jens-maus.de>
* fixed enum type list to output proper enum type names for all internally
known enum types.
* fixed some incorrect naming of "CalendarDPs" enum type which was named
"ClendarDPs".
* fixed inconsistent output of .EnumTypeName() use on unknown enum types.
2017-07-31 Jens Maus <mail@jens-maus.de>
* fixed '+' operator to respect data type ordering when an addition
contained a string.
* fixed a bug where saving a script program via WebUI could take
considerable time if the script program reached a certain amount.
#### BETA15-2017-07-11 (5dc7736) - 2.29.18 Release ##########################
2017-07-07 Jens Maus <mail@jens-maus.de>
* fixed a bug in the signal handler management which was potentially broken
and might resulted in unexpected terminations of ReGaHss.
* fixed bug where object names were always trunctaed to 49 characters so
that GetObject() calls with the full object name didn't match.
#### BETA14-2017-06-03 (8eb738a) Release ####################################
2017-06-01 Jens Maus <mail@jens-maus.de>
* added some verbose error output to more easily identify incorrect uses
of foreach()/while() expressions.
#### BETA13-2017-05-30 (07cb86d) Release ####################################
2017-05-30 Jens Maus <mail@jens-maus.de>
* general code cleanup by having increased the compiler warning level.
* reworked class constructors to initialize member variables in the correct
order so that no compiler warnings are generated anymore.
#### BETA12-2017-05-29 (2fc2389) Release ####################################
2017-05-29 Jens Maus <mail@jens-maus.de>
* slightly reworked internal script function management to manage function
in a more secure way.
2017-05-28 Jens Maus <mail@jens-maus.de>
* output just filename and line number on each Error syslog output rather
the full path and line number in brackets where users thought this might
be the error id.
2017-05-27 Jens Maus <mail@jens-maus.de>
* fixed bug where a dom.GetObject() with a string starting with a number
always returned the object with the number the string started. Thus,
dom.GetObject("2Test") always returned the root object instead of trying
to search for an object with that particular string.
* fixed using LastTimestamp() and LastTimestampSeconds() on channel
objects like this had been possible.
2017-05-26 Jens Maus <mail@jens-maus.de>
* using VarType() and Type() on an uninitialized 'idarray' doesn't end up
in a ScriptRuntimeError anymore and should return valid results now.
#### BETA11-2017-05-24 (8349dc1) Release ####################################
2017-05-24 Jens Maus <mail@jens-maus.de>
* fixed bug in syslog output function where in case an output contained
typeical format specifiers (e.g. '%s') could result in segmentation
faults.
2017-05-23 Jens Maus <mail@jens-maus.de>
* fixed another regression bug where calling .Device() on a HSSDP resulted
in a ScriptRuntimeError.
#### BETA10-2017-05-22 (334e81f) Release ####################################
2017-05-22 Jens Maus <mail@jens-maus.de>
* fixed a regression bug which caused that obj.HssType() was not working
properly anymore in a generic case. This resulted in incorrectly displaying
temperatures in the WebUI with wind directions.
2017-05-21 Jens Maus <mail@jens-maus.de>
* fixed system.Exec() function to be able to be executed without any
parameters without interrupting a script execution.
* fixed typo of "ID_GW_CHANNEL" constant
2017-05-19 Jens Maus <mail@jens-maus.de>
* added a workaround for a commonly but incorrectly use of .AlDestMapDP() on
an AlTriggerDP() acquired object so that only a warning is issued without
stopping script execution. In future, however, we should and will remove
this workaround again.
* fixed a regression bug with .Variable() not having worked anymore after
the recent opcode fixes.
#### BETA9-2017-05-18 (8d2e2bb) Release #####################################
2017-05-18 Jens Maus <mail@jens-maus.de>
* fixed all problems with function name clashes. E.g. the use of
o.ToInteger() and o.BuildLabel() on a valid object 'o' returned the
same 'string' result even though ToInteger() isn't a valid/accepted
function of an object. Something like this was possible at many
places resulting in unwanted side effects. Now a proper
ScriptRuntimeError is issued instead so that script authors can
correct these errors.
2017-05-17 Jens Maus <mail@jens-maus.de>
* fixed a bug where Type() and VarType() was not available for all
possible variable types. Now 'var', 'idarray' and 'object' can also
be queried for their types. Note, however, that for actual objects
only VarType() will be unique since Type() will then return the
actual object type instead of the variable type name.
* fixed a bug in while() and foreach() not raising any error if the
specified condition isn't valid.
* increased maximum number of iterations for foreach()/while() to 50000
to facilitate our current hardware setup.
* fixed /bin/hm_startup process to wait a certain amount of time for the
rega engine to start up. Otherwise errors might occur during startup.
* added Type(), VarType() and ToString() to idarray vartype
* fixed a regression bug which caused that session ids were not correctly
calculated on a CCU2
2017-05-16 Jens Maus <mail@jens-maus.de>
* added missing optional 'long_press' parameter to xmlrpc.ActivateLinkParamset().
* fixed all xmlrpc namespace calls to correctly check for mandatory and
optional parameters so that future calls to the rfd XMLRPC interface won't
end up in random crashes.
2017-05-15 Jens Maus <mail@jens-maus.de>
* fixed bug where calling xmlrpc.ActivateLinkParamset() with only two
arguments resulted in a crashing rfd. Now ReGa will perform some parameter
checks before executing the XMLRPC call.

* fixed some false thread termination error output when terminating
ReGaHss
* fixed bug in script parser where lines starting only with "!" resulted in
commenting out the whole next line as well.
* modified script runtime error output to display the famous '11622' debug
messages as a 'info' log output instead and added a second normal 'error'
output which outputs the reason for the error in a more human readable
form with the complete code attached so that the buggy code can more easily
be identified.
* implemented the following random number generator functions to be usable
within a rega script
system.Random(min, max) - outputs a random integer number between min<>max
or a general random number without specifying
min/max
system.Srandom(val) - Allows to seed the random number generator to
a specific value or without 'val' to a random
value
2017-05-10 Jens Maus <mail@jens-maus.de>

* fixed ToInteger() to correctly truncate real values
* fixed '+' operator to be also used for concatinating a string with
an integer or real value similar to how '#' is doing this

* modified all uses of string operating functions to use their buffer
overflow/underflow safe variants instead.
* fixed incorrect deallocations of certain array-type variables.

2017-04-24 Jens Maus <mail@jens-maus.de>
* PONG events received will now be properly ignored without issuing an error.
This should fix https://github.com/eq-3/occu/issues/44
* added "AutoSaveDomOnExit" rega.conf option to allow to force a DOM config
save upon termination (disabled per default).

2017-04-09 Jens Maus <mail@jens-maus.de>
* fixed a another timer related regession bug which caused that daily timers
resulted in bogus timer executions once a daily timer was executed.
#### BETA4-2017-04-07 (65eed4a) Release #####################################
2017-04-06 Jens Maus <mail@jens-maus.de>
* added "AutoSaveDOMCycle" and "CheckModifiedCycle" rega.conf config options
and restored the old default value of 12h and 10min.
* added "SessionMaxCount" config option to rega.conf to allow to raise max.
HTTP session limit.
* modified command-line usage output to display version and build date.
* fixed another timer related bug which was caused because two threads were
fighting for the same data and suddenly overwrote data of the other thread.
Now a mutex protects use of some public methods, thus should synchronize
access properly.
#### BETA3-2017-04-05 (7f6cd65) Release #####################################
2017-04-05 Jens Maus <mail@jens-maus.de>
* fixed a bug in the time_t conversion routines which didn't convert DST
vs. non-DST conversions correct and overly complicated.
This was the reason for certain DST/non-DST related issues and also
the reason for not formatting certain dates correctly in HM scripts
(see https://homematic-forum.de/forum/viewtopic.php?f=34&t=34439)
2017-04-04 Jens Maus <mail@jens-maus.de>
* replaced all localtime() and gmtime() uses with their reentrant
versions localtime_r() and gmtime_r(). This should hopefully finally
fix all the strange timer related issues with short timers (< minutes)
which was caused by localtime/gmtime using internal buffers, thus old
struct tm values were used ending up in certain runtime problems.
* modified config AutoSave to force a save of the configuration every 60
minutes instead of 12h. Also switched the modified config check to
check every 5 minutes if the config had been changed and then
immediately saving it. Furthermore, switched the autosave at
termination of ReGaHss to the modified check thread instead.
2017-04-03 Jens Maus <mail@jens-maus.de>
* removed artifical max size for string variables. Now a string can have
an arbitrary length like c strings. This allowed to enlarge the size
of rega script programs to be edited which was previously limited to
100KiB. Now an arbitrary long script can be added as a HM script.
* fixed a minor but severe bug in the Timer management which caused
that especially short timers (~ seconds) suddenly stopped because
the end of day information pointed to 1970-01-01 and thus cancelled
further timer executions. Further long term tests have to show,
however, if all timer related problems are really solved by this fix.
2017-03-30 Jens Maus <mail@jens-maus.de>
* added missing data skipping upon termination to all relevant code
passages. This fixes the "invalid free()" segmentation faults upon
termination of ReGaHss which was caused because ReGaHss was trying to
free memory of static instance data. Now ReGaHss can be properly
terminated while freeing memory properly.
2017-03-29 Jens Maus <mail@jens-maus.de>
* fixed bug where upon termination of ReGaHss the current DOM config were
not saved. Now the AutoSave thread will be properly signaled to close its
operation while saving the current config before shutting down.
This should fix issues where changed settings were lost if the system had
been reset immediately after the change.
* fixed the limitation of 200 ReGa script variables per variable list by having
implemented a dynamic resize operation which in theory allows an
unlimited number of variables now.
2017-03-28 Jens Maus <mail@jens-maus.de>
* fixed certain invalid memset() calls potentially caused unwanted crashed.
2017-03-23 Jens Maus <mail@jens-maus.de>
