------------------------------------------------------------------- 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 ------------------------------------------------------------------- Thu Jan 7 15:55:52 UTC 2021 - Andreas Schwab <schwab@suse.de> - Compile with %optflags ------------------------------------------------------------------- Mon Jan 4 13:59:33 UTC 2021 - Bernhard Wiedemann <bwiedemann@suse.com> - Add reproducible.patch to drop build date (boo#1047218) ------------------------------------------------------------------- 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> - Update to version 8.243: + See http://home.thep.lu.se/~torbjorn/pythia82html/UpdateHistory.html - 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 - Update to version 8.223: + 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: + See list of changes at: http://home.thep.lu.se/~torbjorn/Pythia.html or locally at /usr/share/doc/packages/pythia/htmldoc/UpdateHistory.html. - Rebase patches so that they apply cleanly against updated version. - Add pythia-remove-rpaths.patch to remove rpath usage when building shared libraries. ------------------------------------------------------------------- Mon Feb 1 17:02:25 UTC 2016 - badshah400@gmail.com - Update to version 8.215: + See list of changes at: http://home.thep.lu.se/~torbjorn/Pythia.html or locally at /usr/share/doc/packages/pythia/htmldoc/UpdateHistory.html. - Rebase patches so that they apply cleanly against updated version. ------------------------------------------------------------------- Wed Sep 23 21:34:24 UTC 2015 - badshah400@gmail.com - Update to version 8.212: + See list of changes at: http://home.thep.lu.se/~torbjorn/Pythia.html ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Fri Aug 14 11:33:44 UTC 2015 - idonmez@suse.com - 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. ------------------------------------------------------------------- Sat Mar 15 21:21:44 UTC 2014 - badshah400@gmail.com - Update to version 8.185: + This is a bug-fix release, see http://www.hepforge.org/lists-archive/pythia8-announce/2014/000007.html for a summary of changes. ------------------------------------------------------------------- Sat Feb 22 05:10:04 UTC 2014 - badshah400@gmail.com - Update to version 8.183: + This is a bug-fix release, see http://www.hepforge.org/lists-archive/pythia8-announce/2014/000006.html for a list of changes. ------------------------------------------------------------------- Tue Dec 10 23:32:03 UTC 2013 - badshah400@gmail.com - Initial version
