2025-11-10 ------ omnetpp-6.3.0 released ------

2025-07-14 ------ omnetpp-6.2.0 released ------

2025-04-25 Levente Meszaros

* Added -Xev=<num> experimental option. Causes Qtenv to run the simulation

in Fast mode until event #<num>.

Note: -X options are experimental ones that may come and go without

notice.

2025-06-05 ------ omnetpp-6.2.0pre1 released ------

2025-04-15 Levente Meszaros

* Fixed eventlog recording enabling/disabling flags: Settings in the

`eventlog-options` configuration option did not take place.

2025-05-07 Andras Varga

* Fix #1369 "Inifile iteration variable does not accept underscore"

2025-03-20 Andras Varga

* fsutils.cc: Added getLoadedExtensionLibraries(), which returns the list of

shared libraries loaded by the simulation program.

2025-03-05 Rudolf Hornig

* Updated the default value of the `debugger-attach-command` config option

to use the new LSP4E DAP debugger in the IDE.

2024-11-22 Andras Varga

* Print fewer newlines before error messages.

Note: We output a line feed to ensure the error message begins on the start

of the line; however we only need this for stdout, but not on stderr where

we don't output much.

2024-11-22 Andras Varga

* Added `-S` option that suppresses all stdout output ("really silent").

Note: The existing `-s` was actually a "--no-verbose" option, it is also

clarified now in the help.

2024-11-20 Andras Varga

* Added `record-vector-results`, `record-scalar-results` options. They disable

writing a scalar/vector file.

Note: previously it was not possible, because even after disabling the

recording of scalar/statistic/vector items using per-object options,

empty files (just with the run header and vector declarations) were still

created.

2024-10-08 ------ omnetpp-6.1.0 released ------

2024-09-27 Attila Torok

* EnvirBase: fix: Make the MPI implementation of parsim actually get built

in when available and requested, by adding missing inclusions of

platdep/config.h before any WITH_MPI (or WITH_PARSIM) macro usages.

2024-09-27 Andras Varga

* Accept wildcards in config names, e.g. `seed-*-mt`. In

SectionBasedConfiguration, instead of storing config entries in a plain map,

use a matcher list and first-match lookup.

Also, for numeric ranges (e.g. `seed-{0..5}-mt` ) to work, dots between

braces/brackets need to be ignored when looking for the last dot to separate

path and suffix part.

2024-09-27 Andras Varga

* EvnvirBase: fix: make `*.host[*].rng-0 = index` work in omnetpp.ini.

`index` was not recognized ("no such variable")

-

2024-09-10 Andras Varga

* EnvirBase: follow cEnvir change: added getOutputStream().

2024-05-27 Andras Varga

* Inifile parsing: Fix trailing space in section header causing parse

error. This fixes #1167.

2024-05-02 Andras Varga

* Added isAbstractConfig() to cConfigurationEx; implement it

in SectionBasedConfig.

2022-02-02 Andras Varga

* Added the "abstract=<boolean>" config option. Setting it makes the section

abstract, i.e. serve as a base for other sections.

2024-05-02 Andras Varga

* Refined the description of eventlog-snapshot-frequency and

eventlog-options ini file options for clarity.

2024-03-26 Levente Meszaros

* Eventlog Recording: Fix: ComponentMethodBeginEntry was not recorded into

the event log if the called was a channel object. The resulting eventlog

file could not be read by the sequence chart tool.

2024-03-11 Andras Varga

* Output Vector Recording: Include empty vectors in the output vector file.

File Previously, output vectors were only recorded into the .vec file when

the first data item was written. As a result, vectors that were registered

but never written to did not appear in the .vec file. This behavior caused

uncertainty during simulation result analysis, as users could not

distinguish between events (e.g., packet drops) that never occurred during

the simulation and those that were simply not measured or recorded. Now,

empty vectors are also written to the .vec file, eliminating this

uncertainty and providing more complete information.

The old behavior can be requested with the "vector-record-empty=false"

configuration option, in case it is ever needed.

This also fixes the issue that no .vec file was written by a simulation that

only created empty vectors but never wrote data into them.

2024-03-07 Andras Varga

* Output Vector Recording: Follow cEnvir interface change, and remove the

setVectorAttribute() method. Attributes need to be specified in the

registerOutputVector() call instead.

Reason: Otherwise, early vector registration (required for being able to

record empty vectors into the .vec file) is not possible, because setVectorAttribute()

calls would come too late. Also, this is now consistent with the API for recording of

scalars, histograms, etc.

2024-01-17 Andras Varga

* Fingerprint: "statistics" ingredient to ignore disabled (unrecorded)

statistics. This, in theory, is a breaking change, but we doubt using the

"statistics" fingerprint ingredient is a rarely used feature.

2023-10-18 Levente Mészáros

* Fixed check_and_cast in ObjectPrinterRecursionControl, the result

can be a nullptr.

2023-01-16 Andras Varga

* XMLDocCache: Make it own the XML documents it loads. This is needed for

making it possible to assign XML data to NED "object" parameters, see

simulation library changes. Also: XmlDocCache may now be cleared at any

time, because module parameters no longer point into the element trees held

by XmlDocCache, but have their own copies.

2022-03-19 Andras Varga

* EnvirBase: Refactoring: Factor out a loadNEDFiles() function from setup().

2022-05-16 Attila Torok

* Use C++ headers instead of C ones, e.g. <cstdlib> instead of <stdlib.h>

2022-05-19 Attila Torok

* Build: Generate config.h instead of passing macros on the command line

2024-02-01 ------ omnetpp-6.0.3 released ------

2022-07-27 Andras Varga

* EventlogFileManager: state vars commented for clarity

* Fix #933: EventlogFileManager: eventlog recording intervals were ignored

even in Cmdenv

* EventlogFileManager: remove unused ("write-only") state variables

2022-05-18 Attila Torok

2022-09-01 ------ omnetpp-6.0.1 released ------

2022-04-11 ------ omnetpp-6.0 released ------

2022-04-08 Rudolf Hornig

* Fixed default debugger command on Windows. The system() call uses cmd.exe

on Windows, so we have to use 'bash -c' to start opp_ide's shell script.

2022-04-06 Andras Varga

* EventLogFileManager: eliminate (harmless but still) illegal casts found

by UndefinedBehaviorSanitizer.

2022-03-22 Levente Meszaros

* opp_loadlibrary(): use LIBSUFFIX instead of hardcoding "_dbg"

2022-04-05 Andras Varga

* SectionBasedConfiguration: fix invalid cast of NullEntry to

MatchableEntry, found by UndefinedBehaviorSanitizer.

2022-01-05 Rudolf Hornig

* Changed the default debugger command to one that invokes the Simulation

IDE and makes the CDT debugger attach to the simulation process. The command

line is: `opp_ide omnetpp://cdt/debugger/attach?pid=%u`

2022-01-05 Andras Varga

* New `-h` topics: `latexconfigvars`, `sqliteschema`. They are mainly

used for producing info for the Appendices in the manual.

2021-11-30 Rudolf Hornig

* Improved the output of "opp_run -v".

- correctly detects the CLANG compiler (along with its version)

- type of simtime_t type no longer displayed (using double as simtime_t

is no longer supported, so it was always omnetpp::simtime_t)

- large-file-support=yes removed, as 64-bit systems always support long files.

- added architecture display with ARCH_X86_64, ARCH_AARCH64 labels.

2021-11-29 Andras Varga

* SqliteOutputScalarManager: fix typename quoting. It needs to be quoted

as if it was a cPar string expression.

2021-11-07 Andras Varga

* SectionBasedConfiguration: fix for issue #903 ("crash during initialization

when mapping module local rng and setting gobal rng by seed-N-mt* instead of

seed-N-mt")

2021-11-07 Andras Varga

* SectionBasedConfiguration: added MatchableEntry::str() (for debug purposes)

2021-08-05 Attila Torok

* EnvirBase::componentInitBegin(): Set currentModuleId before init stages,

so the log prefix is not there (we have a banner for it now)

2021-07-06 Andras Varga

* Inspectors adjusted to recent cClassDescriptor change (void* -> any_ptr).

2021-06-08 Attila Torok

* Use object->getDescriptor() instead of cClassDescriptor::getDescriptorFor(object)

wherever possible.

2021-06-15 Andras Varga

* InifileReader ported to opp_staticpooledstring

* SectionBasedConfig ported to opp_staticpooledstring.

2021-06-13 Andras Varga

* EnvirBase: readParameter(): pass inifile entry location to cPar as well.

2021-06-13 Andras Varga

* InifileReader: minor refactoring

2021-06-09 Andras Varga

* Report location for parse errors in values coming from ini files

2021-05-17 Andras Varga

* Follow changes in common/stringutil.h

2021-05-13 Andras Varga

* Cosmetics on '// namespace' comments

2021-05-05 Andras Varga

* Switched to the new StringTokenizer class.

2021-05-11 Andras Varga

* SectionBasedConfiguration: cosmetics: camelize variables

2021-05-11 Andras Varga

* Follow changes in common/stringutil.h functions

2021-05-11 Andras Varga

* Use opp_split()/opp_splitandtrim() instead of StringTokenizer.

2021-05-03 Zoltan Bojthe

* InifileReader: bugfix: type mismatch: char vs char*

2021-04-30 Andras Varga

* InifileReader: Improve support of indented continuation lines

2021-04-29 Andras Varga

* SectionBasedConfiguration: better solution for per-object options

specified w/o object path.

2021-04-29 Andras Varga

* SectionBasedConfiguration: leave validation of command-line options

to the validate() function.

2021-04-29 Andras Varga

* Fix: lifecycle listeners added on startup (using EXECUTE_ON_STARTUP())

didn't take effect.

Cause: listeners were added the the boot-time envir, not the permanent

one. Solution: Take over lifecycle listeners from the boot-time envir.

2021-04-29 Andras Varga

* EnvirBase: remove lifecycle-related methods (addLifecycleListener(),

removeLifecycleListener(), notifyLifecycleListeners()), as they were

moved to its base class cEnvir.

2021-04-29 Andras Varga

* More modernizing (NULL -> nullptr, use auto for iterator)

2021-04-24 Andras Varga

* InifileReader: disallow indentation of entries (indentation means

continuation line).

2021-04-21 Andras Varga

* InifileReader: rewritten to support indented lines being continuation

of the previous one.

2021-04-21 Andras Varga

* InifileReader: refactoring

2021-04-19 Andras Varga

* Make the "Config " prefix in inifile section headers optional.

That is, [Config PureAlohaExperiment] may now be also written as

[PureAlohaExperiment], the two are equivalent.

2021-04-15 Attila Torok

* Fix a couple of format-string related bugs when constructing cRuntimeError

2021-04-08 Andras Varga

* Follow cVisitor change: use retval=false in visit(cObject *obj) instead of

EndTraversalException to stop iterating.

2021-02-05 Levente Meszaros

* EventlogFileManager: Implemented snapshot and incremental index support.

IMPORTANT: This means significant (breaking) changes in the elog file format.

New config options: "eventlog-max-size", "eventlog-min-truncated-size",

"eventlog-snapshot-frequency", "eventlog-index-frequency", "eventlog-options"

2020-04-30 Attila Torok

* Properly register "${iterationvarsd}" where needed

2020-12-15 Andras Varga

* NED package exclusions changed to expect package names instead of folders.

As part of this change, the -x command-line option changed meaning (take it

now takes package list instead of folder list); the config option

"ned-exclusion-path" was renamed to "ned-package-exclusions", and env.var.

OMNETPP_NED_EXCLUSION_PATH was renamed to OMNETPP_NED_PACKAGE_EXCLUSIONS,

and their meanings changed too. Note that the NED exclusion feature is new

in 6.0, so there is no backward compatibility issue.

2020-11-11 Attila Torok

* On Windows, try to ensure that if the simulation cannot be started due to

a missing DLL or DLL entry point, a Windows system dialog appears with a

message indicating what exactly is missing. Note that this information cannot

be accessed programmatically at the LoadLibrary call site (!!!).

The solution is to call the SetErrorMode(0) Windows API before loading any

libraries. This only needs to be done if we are running a GUI (Qtenv),

because we don't want bogus command-line simulation batches to be interrupted

with modal dialogs popping up.

2020-11-11 Zoltan Bojthe

* EnvirBase: Removed safety check that prevented the experimental "fakegui"

feature from being used.

2020-11-13 Attila Torok

* Modernizing: Use in-class member initializers wherever possible;

use "=default" syntax for copy constructors where appropriate.

Tool: clang-tidy plus manual editing where needed.

2020-10-10 Andras Varga

* Removed support for USE_OMNETPP4x_FINGERPRINTS.

2020-09-09 Andras Varga

* Follow cIOutputScalarManager change: recorder methods now return a bool

2020-09-07 Zoltan Bojthe

* output vector/scalar managers: Ignore writes in the ENDED state.

Such writes often occur during network teardown, in response to emitted

model change signals, generated by listeners that are still hooked on

those signals.

This change was made necessary by a recent commit that causes listeners

to be still active during module deletion. (Formerly, deleteModule()

started with unsubscribing all listeners in that submodule tree -- that

is no longer done.)

2020-06-23 Andras Varga

* EnvirBase, EventlogFileManager: follow cEnvir changes due to the

introduction of SendOptions and transmission updates.

2020-07-01 Attila Torok

* Fix prefix formatting with %E during initialize (when current event is nullptr)

2020-06-08 Andras Varga

* Added the "parsim-num-partitions" config option

2020-06-10 Andras Varga

* Better error message if getting host name fails

2020-06-07 Andras Varga

* Command-line options: Made -q more permissive: if -c is missing,

assume "General". This is more in line with what Cmdenv does.

2020-06-07 Andras Varga

* Command-line options: Added -e <configoption> (print value of the

given config option).

2020-03-17 Andras Varga

* Implemented "${datetimef}"

2020-03-15 Andras Varga

* Added the "config-recording" configuration option, which controls

the amount of configuration options to save into result files.

2020-03-17 Andras Varga

* Added support for result directory subdivision: ${iterationvarsd}

variable, "resultdir-subdivision" configuration option.

Many file managers and other tools (inc. Eclipse) break down if there are

too many files in single directory (10,000 or more). The common

workaround is to group the files into a subdirectory tree. (For example,

git also uses this technique to store the contents of .git/objects dir).

In OMNeT++, this problem occurs when a parameter study produces too many

result files. To solve it, it is natural to use the iteration variables

to define the directory hierarchy. This commit does it in the following

way:

1. Defines a "$iterationvarsd" variable (run attribute), which is similar

to "$iterationvarsf", only it contains '/' instead of ','.

2. Turning on the new "resultdir-subdivision" config option will cause

"/${configname}/${iterationvarsd}" to be appended to the name of the

results directory. This way, files will be created inside a directory

tree under the results directory.

If you want to set up the directory hierarchy in a different way,

you can do so by setting the "results-dir" config option and appending

stuff to the value. E.g.: results-dir = "results/${repetition}"

2019-12-07 Andras Varga

* Fix eventlogrecorder crash if network is not found.

2019-11-11 Rudolf Hornig

* Updated documentation of the eventlog-message-pattern option: change

"field(pattern)" syntax to "field=~pattern".

2019-11-05 Andras Varga

* Accept expressions as value for (most) config options. For options that

accept values both with and without quotes (types STRING, FILENAME,

FILENAMES, PATH), a heuristic decides whether a string is to be taken

literally or to be evaluated as an expression.

2019-10-23 Andras Varga

* Follow change: cNedValue renamed to cValue

2019-10-21 Andras Varga

* Follow change: cPar::parse() and cExpression::Context ctor now expect a

base directory argument.

2019-10-12 Andras Varga

* Fix quoting of values in result file 'config' lines.

Certain types of config *options*, namely string options and

filename/filename list options, can appear in ini files with optional

quotation marks. This quoting does not affect meaning, and is in fact

removed by cConfiguration::getAsString/getAsFilename methods. These

quotation marks don't need to be preserved when those entries are written

into result files, so we remove them here.

2019-10-10 Andras Varga

* Micro-optimization: LogFormatter to spare cost of event->getClassName()

on each event if possible.

2019-08-01 Andras Varga

* Follow change: intpar_t renamed to intval_t.

2019-07-31 Andras Varga

* Result file managers: refactoring: Introduce 'state' variable to better

ensure correct usage; rename initialize() to openFileForRun(), etc.

2019-07-30 Andras Varga

* Result file version number bumped from 2 to 3.

2019-07-30 Andras Varga

* Several global config options change to be per-run: scheduler-class,

debug-on-errors, print-undisposed, fingerprintcalculator-class.

2017-07-16 Andras Varga

* Follow change: The common::Histogram class now stores binEdges,

binValues plus underflow/overflow instead of bins.

2019-07-24 Andras Varga

* Added check to refuse to generate fingerprint that contains 'f' or 'y' as

ingredient, because cmdenv-fake-gui and computing fingerprint from figures

and display strings are currently experimental features.

2019-07-18 Andras Varga

* Save component type as "typename" pseudo parameter to scalar files.

2019-07-18 Andras Varga

* Output scalar files: Save parameter attrs as well.

2018-07-09 Andras Varga

* Allow recording actual module/channel parameter values into the output

scalar file. Added config option **.param-recording=true/false; implemented

recordParameter() methods.

2018-07-09 Andras Varga

* Result files: Save full config, not only param assignment lines.

2019-07-10 Rudolf Hornig

* Fix Windows-specific build error in stream.seekg() call.

2019-07-03 Andras Varga

* LogFormatter: Fix: Prevent aborting when user enters invalid log prefix in

Qtenv Preferences dialog.

2019-07-03 Andras Varga

* LogFormatter: added "%<" (trim preceding whitespace) diretive.

2019-04-29 Andras Varga

* Follow change: XML parser moved from nedxml to common.

2019-04-25 Andras Varga

* Follow change: cXMLElement ctor changed.

2019-04-16 Andras Varga

* "-h nedfunctions" to list unit conversion functions as well.

2019-04-11 Andras Varga

* Ported constraint evaluator to use the new Expression class. It should

work exactly as before.

2019-04-04 Rudolf Hornig

* Makefile improvements.

2019-04-02 Andras Varga

* Added ned-exclusion-path= config option.

2019-03-21 Andras Varga

* Accept the OMNETPP_NED_PATH environment variable in addition to NEDPATH.

2019-03-21 Andras Varga

* Implemented NED exclusion path (-x <nedexclusionpath> option,

OMNETPP_NED_EXCLUSION_PATH environment variable).

2019-03-21 Andras Varga

* Removed obsolete command-line options -x, -X, -g, -G.

2019-03-21 Andras Varga

* Image path handling changed: Added -i <imgpath> option (may occur

multiple times); removed "./bitmaps" from default image path.

2019-03-21 Andras Varga

* Updated help for the -n option; hide -p which belongs to a feature under

development.

2019-03-20 Andras Varga

* EventlogRecorder: in ModuleCreatedEntry, record

module->getModuleType()->isSimple() instead of module->isSimple().

2019-03-19 Andras Varga

* Do not complain about missing omnetpp.ini if a --network option is

present.

2019-03-19 Andras Varga

* Refactoring: Share ARGSPEC; associated help text updated.

2019-03-19 Andras Varga

* Startup code (ini reading) minor refactoring.

2019-03-14 Andras Varga

* Allow parameters to be specified on the command line.

2019-03-18 Andras Varga

* NED path handling, with behavior change. Multiple -n options are now

accepted. Change: before, $NEDPATH was ignored if a -n option was present,

no longer so.

2019-03-18 Andras Varga

* Args handling: If a command-line option with a value (e.g. -u <ui>) occurs

multiple times, take the last one.

2019-02-27 Andras Varga

* Improve "-h nedfunctions" output: break long lines.

2019-02-27 Andras Varga

* "-h resultfilters" and "-h resultrecorders" to print the descriptions of

the filter/recorder types.

2019-02-22 Andras Varga

* Added support for embedding NED files: EnvirBase::setup() now loads

NED files embedded into the simulation program as string literals

(embeddedNedFiles global variable).

2019-02-11 Andras Varga

* EventlogFileManager: Follow change: ModuleMethodBegin/End renamed to ComponentMethodBegin/End.

2019-01-30 Andras Varga

* EnvirBase: startRun() renamed to prepareForRun(), endRun() eliminated.

startRun() was renamed to break association with startRun() methods of

extension classes like scheduler, output vector manager, output scalar

manager, etc.

endRun() was eliminated for a similar reason. Besides, it only contained

"notifyLifecycleListeners(LF_ON_RUN_END)", and such notifications are

inlined everywhere else.

2019-01-30 Andras Varga

* SqliteOutputScalarManager: fix: there is no longer need to record itervars

as scalars. The same change for the native file format was done in version 5.2.

2019-01-28 Andras Varga

* Fix: Record eventlog button caused crash in Qtenv if there was no network

set up.

2019-01-16 Rudolf Hornig

* Makefiles improved

2018-11-30 Andras Varga

* Remove "./bitmaps;./images" from OMNETPP_IMAGE_PATH, and put them

into the "image-path" config option instead.

2018-06-18 Andras Varga

* SectionBasedConfiguration: cosmetics: terminology change: "group" -> "bin".

2018-08-30 Rudolf Hornig

* Include WITH_OSGEARTH in compiled-in build information string.

2018-06-28 Andras Varga

* Remove obsolete result file recorders.

2018-06-15 Andras Varga

* Remove printing porting hints for 3.x inifiles.

2018-06-27 Andras Varga

* Follow change: Tkenv removed.

2020-01-06 ------ omnetpp-5.6 released ------

2019-12-07 Andras Varga

* Fix: EventLogRecorder crashed if network was not found

2019-07-03 Andras Varga

* LogFormatter: Added "%<" (trim preceding whitespace) directive

2019-05-15 ------ omnetpp-5.5 released ------

2019-04-27 Andras Varga

* XML: fix the issue of accumulating whitespace node content slowing

down the parsing process

2019-03-20 Andras Varga

* Fix: @statistic signal checking used wrong isSimple()

2019-03-14 Andras Varga

* Feature: Allow module parameter values to be specified on the command line,

and they take precedence over values specified in the ini file. The syntax

is similar to that of options. Example:

"opp_run --**.serviceTime=100ms --sim-time-limit=1000s"

2019-02-27 Andras Varga

* Slightly improved -h <topic> output

2019-02-27 Andras Varga

* Feature: Output of opp_run -h resultfilters / resultrecorders now includes

the descriptions of result filter and recorder types.

2019-03-11 Andras Varga

* Fix broken dependencies in Makefiles

2019-01-30 Andras Varga

* SqliteOutputScalarManager: fix: there is no longer need to record

itervars as scalars. The same change for the native file format was

done for version 5.2.

2019-01-28 Andras Varga

* Fix: Check for existence of eventlogManager because the 'record eventlog'

button caused crash in Qtenv if there was no network set up.

2018-06-25 ------ omnetpp-5.4.1 released ------

2018-06-14 Rudolf Hornig

* Envirbase: fix unbalanced #endif

2018-06-11 ------ omnetpp-5.4 released ------

2018-06-08 Attila Torok

* EnvirBase: implemented ensureDebugger() which replaces attachDebugger().

The method of attaching a debugger has been enhanced. I.e. it can detect

when the process is already being debugged, and does not launch another

debugger in that case. Also, when launching a debugger is needed, it checks

beforehand that external debuggers are permitted to debug this process.

* attach-on-startup now detects the debugger before launching one

* debug command (debugger-attach-command config option) can now be

overridden by the OMNETPP_DEBUGGER_COMMAND env. var.

* Use lldb as default debugger on macOS - gdb is not codesigned.

* Adjust description of debugging-related config options.

2018-04-11 ------ omnetpp-5.3 released ------

2018-03-01 Andras Varga

* Follow histogram API changes.

2018-01-26 Andras Varga

* Follow histogram API changes.

2017-01-16 Andras Varga

* Replace gettimeofday() occurrences with opp_get_monotonic_clock_usecs(),

and struct timeval with plain int64_t.

2017-11-26 Andras Varga

* Follow NED->Ned and MSG->Msg naming change in class/function names

* loadExtensionLibrary(): add "_dbg" suffix when in debug mode (Debug

executables prefer loading debug libraries.)

2017-04-06 Andras Varga

* Modernizing: use C++11's range-based for loops where applicable, using

clang-tidy's modernize-loop-convert.

* Modernizing: replace INT64_PRINTF_FORMAT and LL with C++11's PRId64.

Note: PRId64 includes the "d" that was not part of INT64_PRINTF_FORMAT

alias LL.

2017-07-12 Andras Varga

* Output scalar file recorders: sum and sqrSum are no longer saved for

weighted statistics. This is to follow recent cStddev/cWeightedStddev

change.

2017-07-13 Andras Varga

* Output scalar files: do not save numeric iteration variables (of

parameter studies) as scalars. Instead we'll add them (as scalars)

at load time, if needed.

2017-06-21 Andras Varga

* Cleanup: remove the leading "c" from the names of remaining classes,

namely cXMLDocCache, cFileSnapshotManager, cAkOutputVectorManager

2017-06-22 Andras Varga

* Switch to new scalar/vector file recorders: The default values for

the outputscalarmanager-class= and outputvectormanager-class= config

options are now the new classes OmnetppOutputScalarManager and

OmnetppOutputVectorManager. These classes rely on the new result

file writer classes in common/.

The old classes cIndexedFileOutVectorManager and cFileOutScalarManager

still exist. They will be removed in a later version of OMNeT++.

2017-06-22 Andras Varga

* Fix: force SQLite result file recorder classes to be included into

simulation executables by the linker.

2017-04-04 Andras Varga

* Old result file recorders: save iteration variables separately from

run attrs, into 'itervar' lines.

2017-03-30 Andras Varga

* Refactoring: RunData class converted a collection of utility functions

(ResultFileUtils). Results in less state and more flexibility.

2017-07-12 Andras Varga

* EnvirBase: changed the lifecycle of several plugin objects to per-run,

i.e. those objects are now deleted and re-created between runs. Affected

plugins: event log recorder, output vector file recorder, output scalar

file recorder, snapshot recorder, future event set (FES).

The corresponding configuration options have also become per-run options:

eventlogmanager-class=, outputvectormanager-class=, outputscalarmanager-class=,

snapshotmanager-class=, futureeventset-class=.

Side effect: in output vector files, vector IDs now start again from 0

at the start of each run when running multiple runs. Before, they continued

from where the previous run left off.

* EnvirBase: refactoring: replaced CREATE_BY_CLASSNAME() macro by

createByClassName() template function

2017-05-25 Rudolf Hornig

* Updated makefiles for speeding up the build:

- generated files are created only once, even when using parallel build

- binaries are copied to their final destination using proper makefile

targets

2017-06-08 Attila Torok

* EnvirBase: follow cEnvir changes (addition of refOsgNode()/unrefOsgNode())

2017-03-30 Andras Varga

* Result file recorders: space changes in result files for consistency

and to minimize space differences with new recorders. Affected classes:

cFileOutputScalarManager, cFileOutputVectorManager, and

cIndexedFileOutputVectorManager

2017-05-08 ------ omnetpp-5.1.1 released ------

2017-03-31 ------ omnetpp-5.1 released ------

2017-03-16 Andras Varga

* Added new classes OmnetppOutputScalarManager, OmnetppOutputVectorManager

which rely on result file writer classes in envir. These classes are not

activated yet (the old classes cIndexedFileOutVectorManager and

cFileOutScalarManager are still the default result recorder classes.)

* Added the cFileOutputVectorManager_merged class, which is

an intermediate state (cIndexedFileOutVectorManager and its

base class merged.)

2017-03-16 Andras Varga

* SQLite result file managers changed to use corresponding result file

writer classes in the common library.

2017-03-17 Rudolf Hornig

* build: removed obsolete targets in envir's Makefile

2017-03-16 Rudolf Hornig

* Fix: Detection of release vs. debug mode collision is now safer on

Windows 7 (GetProcAddress was not reliable).

2017-03-10 Andras Varga

* SQLite result file recording: 'histattr' table renamed to 'statisticattr'.

2017-03-02 Andras Varga

* SectionBasedConfig: fix bug in unrollConfig(). When doing "-q runs",

seed-set=${10,20,30} caused assertion failure near sectionbasedconfig.cc:650.

2017-02-23 Andras Varga

* Fix #995: Assert condition fails for ini files with CRLF line

terminators in inifilereader. Cause: right-trimming of the line was lost

when converting from FILE* I/O to iostream in late last year for 5.1pre2.

2017-03-16 Rudolf Hornig

* Detecting whether the loaded model is using release or debug mode

libraries is now safer as we are not just testing for the presence

of a symbol that is available only in the release mode, but also checking

for the actual value of that variable. This was necessary because on

Windows 7 the GetProcAddress() function sometimes returned a non-null
