Mon Nov 17 08:51:56 UTC 2025 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.316:
* The DIRE parton shower is no longer supported and consequently
has been removed in this release.
* The reorganization of fragmentation models, begun in 8.313,
continues.
* New code for the cross section of the production of t-tbar
pairs in hadron collisions near the threshold, both above and
below it.
* New options to add non-singular and higher-order terms to the
splitting kernels for timelike showers, along with a new
example program main303.cc.
* New options to regulate the running of alphaS in the infrared,
by freezing it at a maximum value, and/or by shifting the
argument by a number of order LambdaQCD.
* Improved version of DIS kinematics reconstruction. Namely the
lepton mass is appropriately accounted and phase-space cut for
Q2min accounts also masses for final-state partons.
* Introduction of parameters StringFragmentation:eJunctionCutoff
and StringFragmentation:mJunctionCutoff allows for the
modification of stopping conditions on the fragmentation of
the first two junction legs.
* The default value of StringFragmentation:stopMass has been
changed from 1.0 GeV to 0.8 GeV, the same value as used in
PYTHIA 6.4.
* Added the Detroit tune (Agu22) to the list of available tune
presets.
* RandomState of the random-number generator is now saved before
the generation of each event starts.
* Support has been added for parallel running of plugins.
* New RivetHooks plugin allows for Rivet analyses to be run via
the plugin structure with Init:plugins =
{libpythia8rivet.so::RivetHooks}, including in parallel.
* The new plugin HepMC3Hooks allows users to write output to
HepMC3 by loading.
* Added the ability to include purely Pythonic code in the
pythia8 Python module.
* Updates to the Hist class:
- Introduced new methods: getBinCenter(int iBin),
getBinError(int iBin), and getBinError2(). Equivalent
versions getBinCenters(), etc., return a vector of doubles
for all bins.
- Added an optional third argument to the Hist::fill() method,
to allow for weighted uncertainties that are not purely
stochastic. Thanks to Claire Bergman.
- Added new method Hist::getXPercentile() to extract
percentiles from histograms.
- Added the method Hist::yodaTable to enable printing a Hist
to the ESTIMATE1D_V3 format from YODA.
* New particle data method(s) mSelInRange selects the mass of a
particle according to a Breit-Wigner shape, but within a range
that is determined event-by-event.
* A small internal analysis of differential jet rates has been
added to main164. Also, legacy HepMC2 support has been added
to main164.
* The SigmaTotal::calc(...) code has been rearranged so as to
provide a clean abort when the energy is too low, rather than
a segmentation fault.
* Moved -pthread option to the Makefile.
* Updated many of the references to now include hyperlinks to a
publicly accessible version of the reference.
* Fixed an issue where the post-hoc and in-situ flavor
variations for hadronization, see Hadronization Variations,
did not match if particle decays were turned on, as the
in-situ weights did not account for flavor variations in the
hadron decays.
* Fixed a bug where tuning parameters are incorrectly loaded
when specified inside a subrun in a .cmnd file.
* Fix trial hadron generation in
StringFragmentation::kinematicsHadronTmp used in the
closepacking and thermal string breaking frameworks.
* The introduction of StringZ:deriveLundPars inadvertently broke
the behaviour for when only bLund is derived,
StringZ:deriveLundPars = 1. This has now been fixed.
* Fixed the spelling of the addAtribute method of the
PythiaToHepMC class to addAttribute. Also, added a
specialization for this method for integer attributes, as is
already done for double attributes.
* Fixed an issue with the toString helper method which formatted
numbers greater than 1e+6 with an exponent ending in zero
incorrectly, e.g. 1e+10 would be returned as "1e+1".
* Fixed issue with Settings::readFile where for some systems an
empty line could cause a std::out_of_range crash.
* A bug was fixed that led to a pointer to the wrong
ParticleData object when a Pythia object was created from the
Settings and ParticleData of another Pythia instance.
* Tiny cosmetic fix so that a total cross section is not
attempted to be initialized if not both incoming particles are
hadrons (or photons).
- Minor rebase of patches for update:
* pythia-honour-env-cxxflags.patch
* pythia-remove-rpaths.patch
- Split off new shared lib packages for new libraries:
libpythia8hepmc3 and libpythia8rivet (for Leap 16 and newer).
-------------------------------------------------------------------
Fri Aug 15 04:20:08 UTC 2025 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.315:
* Fix bug in the Lund symmetric fragmentation function (LSFF).
It concerns the case where diquarks or strange quarks are
assumed to be produced at a later average time than the up and
down quarks.
* Some changes in the Hidden Valley machinery. Several automatic
rescalings of (safety) parameters and constants to allow a
broader range of HV mass scales, including ones below the QCD
one.
* The prefix for custom weights can now be specified with the
setting Weights:prefix which is by default empty.
* The logic behind the construction of parton-shower histories
in CKKW-L merging has been improved.
* Fixed two bugs in PartonLevel.cc:
- When checking if beams are point-like (to determine if ISR
and beam remnants), a lepton check was not performed for the
second beam (B).
- An incorrect check was made when calculating maximum weights
for FSR decays with W/Z.
* Fixed a rare bug in StringFragmentation::setHadronVertices
that caused a segmentation fault when the string endpoints are
c or b quarks, and a quark mass offset correction is
introduced.
* Fixed typos in the documentation for Hadronization Variations
that do not effect that results of Pythia.
* Reverted beam particles back to raw pointers for technical
reasons.
* An incorrect type declaration in 8.314 invalidated the new
option to derive the a and b parameters from the average and
RMS width of the Lund FF, causing this option to fail for any
choice of input parameters, corrected now.
* Fixed a typo in the MPI initialization when using saved grid
which caused an out-of-access memory read.
- Minor re-base of reproducible.patch for update.
-------------------------------------------------------------------

-------------------------------------------------------------------
Wed Jul 26 22:12:11 UTC 2023 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.310:
* Production of quarkonia is now available via the simple
timelike shower, see Onia Showers for details.
* Added a new feature that allows producing user-defined
resonances in hadronic rescattering. Newly added particles can
be produced as resonances if they set varWidth = on.
* A number of changes have been made to the heavy ion machinery.
* Included possibility to sample intermediate photon virtuality
also for externally provided events using built-in photon flux
for protons.
* Included possibility to generate DIS events with a
(anti-)neutrino beam.
* The TopRecoilHook, formerly available separately, has now been
integrated into the SimpleTimeShower.
* Introduced a new use plugin system, see Plugins for details.
* The arguments to the setSigmaPtr method are now shared
pointers. Additionally, addSigmaPtr has been introduced with
the previous behaviour of setSigmaPtr, and the new setSigmaPtr
overrides all previously added pointers.
* A similar change has been made for the setResonancePtr method
with the addition of the addResonancePtr method.
* The new Logger class now handles printing such as
initialization information and diagnostic messages. For more
information about this class, see the Logging page.
* The new BeamSetup class has been introduced to handle the beam
configuration, including initializing and changing beam
identities, kinematics and parton distributions.
* Modified interface to LHAPDF6 to allow for multi-threading.
* Updated the Python interface to use pybind11 version 2.10.4
which is compatible with Python 3.11.
* Fix for the Python interface working with gcc13.
* Fixed a bug in the Python interface which prevented main162.py
from running correctly when passing a custom function for
initialization.
* Updated the Lambda_b0 lifetime to c*tau = 0.44 mm. The value
was rounded to two significant digits since PDG and HFLAV do
not quite agree to three digits.
* Included several small fixes in response to running an LLVM
static code analysis.
* Fixed out-of-range access when calling Hist::getYMin and
Hist::getYMax for a histogram that has not been booked.
* Fixed BeamRemnants:unresolvedHadron option that was broken and
had no effect since 8.307.
* Removed use of simple-template-ids in SusyLesHouches.h to make
compliant with C++20.
* Fixed dipole sorting behaviour in ColourReconnection which
resulted in an ordering that depended on the current memory
state of the program.
* Changed the default for Parallelism:balanceLoad to on and
updated the documentation. This ensures each thread will
always generate the same number of events.
* Added the += notation for settings vectors, as well as the
include = fileName directive, which allows for additional
settings files to be directly read in.
* Fixed a bug in the bookkeeping the number of hadrons in the
string fragmentation.
- Major rebase of pythia-remove-rpaths.patch for updated version.
-------------------------------------------------------------------
Sun Feb 27 23:05:39 UTC 2022 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.307:
* Extensions to the hadronic cross sections and beam types used
for hadronic rescattering and cascades in the atmosphere.
* Improvements for hidden valley scenarios.
* A new framework for parallelisation (in addition to the
existing openMP option).
* A number of other technical improvements and bug fixes (full
list here: https://pythia.org/history/index.html).
- Minor rebase of patches to apply cleanly, without fuzz.
-------------------------------------------------------------------
Wed Jan 5 16:00:14 UTC 2022 - Atri Bhattacharya <badshah400@gmail.com>
- Drop HepMC2 dependency and build without hepmc2 support; largely
superseded by HepMC(3) and this change allows Leap 15.x builds
to proceed without HepMC2-HepMC conflicts.
- Add BuildRequires: fastjet-plugin-siscone-devel which is needed
for one of the tests (test number 111).
-------------------------------------------------------------------
Sun Dec 12 21:15:04 UTC 2021 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.306:
* Fixed the incorrect scale being set when applying the POWHEG
veto, i.e. main31.cc. Note that the number of emissions is
correct in 8.303, but is incorrect in 8.304 and 8.305.
* Fixed repeated initialization causing an ever expanding
physics pointer list in the main Pythia class.
* Fixed issue for HepMC output from Vincia, which would
previously issue warnings about inconsistent mother/daughter
relationships.
* Removed assert statements from Angantyr.
* Shortened Pythia constructor header.
- Rebase pythia-honour-env-cxxflags.patch and
pythia-makefile-destdir-support.patch to apply cleanly.
- Major rebase of pythia-remove-rpaths.patch for updated version.
- Drop patch not required any more:
* pythia-disable-example23-req-MixMax_h.patch: Examples can now
be disabled by passing options to the run script.
- Change BuildRequires to pkgconfig based ones wherever
appropriate.
- More examples need linking against gmp explicitly: add fixes for
all necessary examples to patch pythia-example71-link-gmp.patch
and rename it to pythia-examples-link-gmp.patch.
- Build with Rivet and HepMC(3) support: add HepMC-devel,
pkgconfig(rivet) BuildRequires.
- Update URL and source URL in keeping with upstream.
- Minor improvements to package summaries.
- Run spec-cleaner for minor cleanups.
-------------------------------------------------------------------
Fri Apr 16 12:30:00 UTC 2021 - Bernhard Wiedemann <bwiedemann@suse.com>
- Fix build for Leap 15.3
-------------------------------------------------------------------

-------------------------------------------------------------------
Sun Jan 3 17:56:27 UTC 2021 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.245:
* Significant speedup of parton distribution handling.
* Several fixes to avoid out-of-bound evaluation of vectors in
the merging code.
* Several fixes to correctly handle CKKW-L merging of EWkino-
and higgsino-processes have been included.
* Include the functionality for MC@NLO-Delta matching with
aMC@NLO.
* Further bug fixes for the hard process name handling for
weak-boson-fusion-like processes, that led to an incorrect
counting of additional emissions.
* Small fixes to history construction in the presence of
multiple resonances.
* The primordial kT for LHE files is now set by the
BeamRemnants:primordialKThard average value, rather than the
LHE scale, since the latter may be quite low e.g. in the
POWHEG approach.
* The problem of "dangling" gluons causing changing color flows
in SimpleTimeShower for top decays is now fixed.
* Extra check added to SimpleSpaceShower for the case where a
small daughter PDF value can lead to an infinite loop if PDF
variations are switched on.
* Bug fixed in the new possibility to let particles with narrow
widths (such as onia states) obtain a simple Breit-Wigner
distribution, specifically for MPIs, introduced in 8.240.
* An indexing bug, for the scattering lepton in DIS events with
photon radiation allowed, has been fixed.
* Added a few copy constructors to match corresponding
assignment operators, to avoid warnings for some compilers.
* Small fix in cross section calculation of main89.cc.
* Fixes in configure and examples/Makefile to have ROOT examples
work again.
* main**.cmnd, ** = 81-84, 87-88 have been slightly modified
such that linking to LHAPDF6 is not required by default.
* A bug in the XML-to-HTML conversion has led to the
indiscriminate removal of "more" from the HTML manual, notably
in Pythia::moreDecays().
- Add patches:
* pythia-example71-link-gmp.patch: Fix building example 71 by
adding -lgmp to the linker flag.
* pythia-disable-example23-req-MixMax_h.patch: Drop a test that
requires the non-free MixMax.h header (which we delete).
- Use autopatch to setup source dir and apply patches
automatically.
-------------------------------------------------------------------
Sun Mar 1 11:10:02 UTC 2020 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.244:
* The combination of weight variations, within the context of
uncertainty bands, has not been well documented and therefore
prone to misunderstandings. Now the behaviour of
Info::getGroupWeight() has been made transparent, and the
documentation in Variations has been improved. The main121.cc
example has been modified accordingly.
* Restore the capability to set width and lifetime of a
resonance separately (see change in 8.240). Now the lifetime
is set from the width only if the allowCalc() method of the
resonance class returns true.
* Updated handling of Powheg files, such that files with
multiple/variable number of real emissions can be handled. The
default value of the POWHEG:nFinalparameter has been changed
to -1, see the POWHEG Merging documentation.
* Limit the amount by which transverse smearing of the
space-time quark-antiquark string breakup vertices can give
large shifts, which may translate into unreasonably long
invariant times being assigned to primary hadron production
vertices. This is regulated by the new HadronVertex:maxSmear
parameter. Even so, large hadron production invariant times
may still occur occasionally by imperfections in the
reconstruction around multiple gluon corners, so
HadronVertex:maxTau gives the possibility to reject the
hadrons of such a parton system and try again. Also some other
related changes.
* Fixes for consistent storage of production vertices in units
of mm. Thanks to Christopher Plumberg.
* Number of weights in info reset to 1 for each new init call.
- Drop manual fixes in specfile that are no longer needed:
* No unusual hidden files to delete.
* Buildroot doesn't get copied into config files.
* No more spurious exec permissions in plain files.
-------------------------------------------------------------------
Wed Aug 21 08:06:55 UTC 2019 - Atri Bhattacharya <badshah400@gmail.com>

- Rebase existing patches to apply cleanly.
-------------------------------------------------------------------
Fri May 3 12:49:40 UTC 2019 - Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.240:
+ See
http://home.thep.lu.se/~torbjorn/pythia82html/UpdateHistory.html
- Rebase existing patches to apply cleanly.
- Disable boost and drop boost BuildRequires as it is no longer
needed when compiling against LHAPDF >= 6.2.
- Remove unnecessary hidden files not cleaned up by build.
- Cleanups using spec-cleaner.
-------------------------------------------------------------------
Mon Apr 30 22:09:08 UTC 2018 - badshah400@gmail.com
- Update to version 8.235:
+ See
http://home.thep.lu.se/~torbjorn/pythia82html/UpdateHistory.html
- Rebase pythia-remove-rpaths.patch
- Drop bundled header file MixMax.h which is not used by pythia
directly and violates GPL copyright.
- Update License to GPL-2.0-or-later in keeping with upstream
change.
- Use %%license to install COPYING file instead of %%doc.
- Remove no-longer needed post-install mosifications:
+ The correct permission for pythia8-config binary is set by
install script; stop setting it manually
+ Rpaths are already removed from the shared libraries; don't
execute chrpath to do this. Also drop BuildRequires: chrpath.
+ Don't remove non-existent backup file.
-------------------------------------------------------------------
Mon Oct 9 10:20:22 UTC 2017 - badshah400@gmail.com
- Update to version 8.230:
+ Long list of changes, see
http://home.thep.lu.se/~torbjorn/Pythia.html.
- Drop python-dont-force-std-cxx98.patch, incorporated into
upstream sources.
- Rebase existing patches.
-------------------------------------------------------------------
Thu Aug 31 22:16:11 UTC 2017 - badshah400@gmail.com
- Build with HepMC2-devel < 3, since pythia tests fail when built
against HepMC-devel >= 3.
-------------------------------------------------------------------
Mon Jul 31 16:21:15 UTC 2017 - badshah400@gmail.com
- Update to version 8.226:
+ See list of changes at:
http://home.thep.lu.se/~torbjorn/pythia82html/UpdateHistory.html
- Rebase patches for update.
- Add python-dont-force-std-cxx98.patch to prevent usage of
--std=c++98 and instead inherit default compiler flags; using
c++98 causes conflicts with dependencies such as fastjet which
are built using default compiler std, leading to build failures
for openSUSE > 1320 (where fastjet is compiled with --std=c+=14
support). Tests in the check section show that this does not
have any untoward repercussions.
-------------------------------------------------------------------
Sun Feb 5 16:42:33 UTC 2017 - badshah400@gmail.com
- Use individual libboost-*-devel packages instead of boost-devel
(only for suse_version > 1325).
-------------------------------------------------------------------
Thu Feb 2 04:05:24 UTC 2017 - bwiedemann@suse.com
- Fix build with rpm-4.13 that creates no .orig file
-------------------------------------------------------------------
Wed Jan 25 09:46:08 UTC 2017 - badshah400@gmail.com

+ See list of changes at:
http://home.thep.lu.se/~torbjorn/Pythia.html
or locally at
/usr/share/doc/packages/pythia/htmldoc/UpdateHistory.html.
- Pass "-std=c++14" to CXXFLAGS as it is required for building
with fastjet support.
- Move installation of shell env definitions to %install section;
this avoids an rpmlint warning and is a better place to do the
installation rather than the %build section.
-------------------------------------------------------------------
Sun Jan 1 13:06:18 UTC 2017 - jengelh@inai.de
- Trim descriptions; only have the full one on the most important
package. RPM group corrections.
-------------------------------------------------------------------
Wed Sep 7 03:45:36 UTC 2016 - badshah400@gmail.com
- Modify pythia-remove-rpaths.patch to make disabling rpaths
optional, specified by passing the "--disable-rpath" option to
configure. Pass said option at the %build stage to prevent
rpath usage in build shared libraries.
-------------------------------------------------------------------
Fri Sep 2 01:42:56 UTC 2016 - badshah400@gmail.com
- Update to version 8.219:

-------------------------------------------------------------------
Fri Sep 4 09:17:48 UTC 2015 - badshah400@gmail.com
- Update pythia-honour-env-cxxflags.patch to really fix the
issue (mentioned in previous entry) for all cases.
-------------------------------------------------------------------
Wed Sep 2 03:22:30 UTC 2015 - badshah400@gmail.com
- Update pythia-honour-env-cxxflags.patch to fix a minor issue
with the pythia8-config script when system CXXFLAGS are passed
during compilation.
-------------------------------------------------------------------
Fri Aug 14 23:52:54 UTC 2015 - badshah400@gmail.com
- Fix the location pointed to by PYTHIA8DATA env variable saved in
/etc/profile.d/pythia.*; remove %{appname} macro as nothing uses
it any more.
- Use %configure instead of ./configure (remove duplicate
specification of "--prefix=PATH").
- Add pythia-honour-env-cxxflags.patch to allow compilation with
CXXFLAGS set by env appended to default compilation flags; this
allows the build to honour RPM_OPT_FLAGS.
- Fix some unusual characters in the descriptions.
-------------------------------------------------------------------
Fri Aug 14 11:44:09 UTC 2015 - badshah400@gmail.com
- Verify installation by running select bundled tests in a %check
section.

- Change postinstall scripts to run ldconfig directly
-------------------------------------------------------------------
Fri Aug 14 05:18:52 UTC 2015 - badshah400@gmail.com
- Update to version 8.210:
+ Bug fix in CKKW-L merging for LHE files, such that the
factorization and renormalization scales are set by the SCALUP
value if the muf2 and mur2 LHEF3 attributes have not been set,
and the user has not set any explicit values; this change
restores the PYTHIA 8.1 behaviour.
+ Various technical improvements in the machinery for hard
diffraction.
+ Correct quark flavour selection when a string spanned directly
between two junctions is split up.
+ Check that SK-I and SK-II colour reconnection machineries only
are called for event topologies they are set up to handle.
+ Bug fixes in partial widths of the W' boson. Results are
correct when the W' is a simply rescaled copy of the W, but
not for more general couplings. Thanks to Mihail Chizhov.
+ Minor fix in default location of PDF data files in the
constructors. No practical consequence since correct
non-default values are used.
+ Tiny fix in the configure script, so that CXX options
containing an equal sign are parsed correctly.
- Changes from version 8.202 through 8.209:
+ See /usr/share/doc/packages/pythia/htmldoc/UpdateHistory.html.
- Add pythia-makefile-destdir-support.patch to enable DESTDIR
support in the Makefile; makes configure stage buildroot-free
and prevents an ugly BUILDROOT trace in the shlib.
- Enable additional bindings now that all necessary deps are in
Factory; new subpackage: libpythia8lhapdf6.
- Add BuildRequires: chrpath; required to cleanup rpath in
libpythia8lhapdf6.so.
-------------------------------------------------------------------
Fri Oct 17 06:09:48 UTC 2014 - badshah400@gmail.com
- Update to version 8.201:
+ Undocumented changes
- Changes from version 8.200:
+ Long list of changes, see announcement here:
https://www.hepforge.org/lists-archive/pythia8-announce/2014/000009.html
- Packaging changes:
+ Rename pythia-libs to libpythia8 to satisfy rpmlint (although
the package only includes one unversioned shlib)
+ Documentation files moved from toplevel dir in source to
"share" subdir, adapt specfile accordingly
+ pythia8-config.in is now replaced by the script pythia8-config
and does not require any tweaking in specfile to get right
paths
+ configure options changed, allowing to automatically install
to libdir where it needed to be manually copied to /usr/lib64
for the x86_64 arch
+ Package new headers directory: %{_includedir}/Pythia8Plugins/
+ Package new pdf documentation: %{_docdir}/%{name}/pdfdoc/.
-------------------------------------------------------------------
Thu Sep 4 23:49:37 UTC 2014 - badshah400@gmail.com
- Update to version 8.186:
+ New user hook to help experimentation with colour
reconnection, in particular in relation to resonance decays
+ New set of parameters StringFlav:probQQ1toQQ0join, used to
pick diquark spin when two already produced quarks are to be
joined into a diquark
+ Possibility to map the bookkeeping of exotic unresolved
incoming beams in Les Houches event files onto neutrino beams,
see LesHouches:idRenameBeams; primarily intended for dark
matter annihilation
+ A correction to the graviton (G^*) + parton hard processes
(5003-5005) to account for off-shell G^* production; the
previous formula assumed the graviton was on-shell and
could greatly overestimate the low-mass tail of the G^*.
+ Bug fixes in examples/JetMatching.h, for uninitialized
boolean, and number of partons to match for heavy flavour
handling. The former bug was introduced with the new
matching schemes in version 8.185 and affected matching to
ALPGEN, since no events were rejected
+ Differentiate the reading of ALPGEN masses, so that vanishing
c or b masses in ALPGEN are not unwittingly used where
inappropriate; also protect the c and b masses from being set
too low in TimeShower and SpaceShower, so that flavour
thresholds are not messed up
+ Reduce number of maximum violation warnings in SpaceShower by
leaving some headroom for branching weights
+ Bug fix that hasVetoed in Pythia.cc was not reset correctly in
some specific cases
+ Bug fix in PartonLevel.cc where a reference could become
invalid
+ Improvements and bug fixes in junction handling
+ Bug fix to not reuse colour indices in double diffraction
+ Bug fix in the calculation of the average mass threshold of
open decay channels of a resonance; reduced
ResonanceWidths::MASSMIN parameter value.
+ Correct typo in left-right symmetry documentation
+ Other minor fixes.
