Grondona" Date: Mon, 19 Jun 2017 13:58:57 -0700 Subject: [PATCH 03/41] build: remove all autotools generated output files Maintaining the autotools generated files in version control is a huge pain in the rear end. Every time someone runs ./bootstrap on a new system they create huge amounts of unnecessary churn. Yes, this requires that all developers and users working from a git checkout have compatible autotools installed on their system, so that they can successfully run ./bootstrap and ./configure. However, the alternative is a big mess and who knows how many years of therapist payments. --- Makefile.in | 807 - aclocal.m4 | 1341 -- config.h.in | 450 - config/Makefile.in | 484 -

Grondona" Date: Mon, 19 Jun 2017 14:07:57 -0700 Subject: [PATCH 05/41] pdsh: use straight dlopen instead of libltdl Dump libltdl in favor of straight dlopen/dlsym for pdsh modules. The new libltdl wrapper is a whole thing of its own and a big burden to use (it wants to be installed as a subproject inside of the project which uses it) This likely means pdsh dynamic modules are no longer supported on systems. Likely those systems don't work now anyway. In the future if an unlikely port is needed to a system requiring libltdl, it should be possible to tackle re-implementation of libltdl (or some other portability layer) at that time. --- configure.ac | 8 +- src/pdsh/Makefile.am | 8 +- src/pdsh/ltdl.c | 4528 ------------------------------------------ src/pdsh/ltdl.h | 366 ---- src/pdsh/mod.c | 35 +- 5 files changed, 11 insertions(+), 4934 deletions(-) delete mode 100644 src/pdsh/ltdl.c delete mode 100644 src/pdsh/ltdl.h diff --git a/configure.ac b/configure.ac index 98f1229d..b8e394bb 100644 --- a/configure.ac +++ b/configure.ac @@ -33,13 +33,7 @@ AC_PROG_INSTALL AC_PROG_LN_S AC_PROG_MAKE_SET AC_DEBUG - -# -# Libtool and ltld.[ch] support -# -AC_LIBTOOL_DLOPEN -AC_PROG_LIBTOOL -AC_LIB_LTDL +LT_INIT AM_CONDITIONAL(WITH_GNU_LD, test "$with_gnu_ld" = "yes") diff --git a/src/pdsh/Makefile.am b/src/pdsh/Makefile.am index 2359e204..1d1b7be7 100644 --- a/src/pdsh/Makefile.am +++ b/src/pdsh/Makefile.am @@ -13,19 +13,17 @@ bin_PROGRAMS = pdsh.inst if WITH_STATIC_MODULES MODULE_LIBS = $(top_builddir)/src/modules/libmods.la else -MODULE_FLAGS = -export-dynamic $(AIX_PDSH_LDFLAGS) -LTDL_FILES = ltdl.h ltdl.c -LTDL_LDADD = $(LIBADD_DL) +MODULE_FLAGS = -export-dynamic $(AIX_PDSH_LDFLAGS) -ldl endif -pdsh_LDADD = $(READLINE_LIBS) $(LTDL_LDADD) +pdsh_LDADD = $(READLINE_LIBS) pdsh_LDFLAGS = $(MODULE_LIBS) $(MODULE_FLAGS) \ $(top_builddir)/src/common/libcommon.la pdsh_inst_LDADD = $(pdsh_LDADD) pdsh_inst_LDFLAGS = $(pdsh_LDFLAGS) -pdsh_SOURCES = $(PDSH_SOURCES) $(LTDL_FILES) +pdsh_SOURCES = $(PDSH_SOURCES) pdsh_inst_SOURCES = $(pdsh_SOURCES) nodist_pdsh_SOURCES = testconfig.c nodist_pdsh_inst_SOURCES = config.c diff --git a/src/pdsh/ltdl.c b/src/pdsh/ltdl.c deleted file mode 100644 index 3f08a757..00000000 --- a/src/pdsh/ltdl.c +++ /dev/null @@ -1,4528 +0,0 @@ -/* ltdl.c -- system independent dlopen wrapper - Copyright (C) 1998, 1999, 2000, 2004, 2005 Free Software Foundation, Inc. - Originally by Thomas Tanner - This file is part of GNU Libtool. - -This library is free software; you can redistribute it and/or -modify it under the terms of the GNU Lesser General Public -License as published by the Free Software Foundation; either -version 2 of the License, or (at your option) any later version. - -As a special exception to the GNU Lesser General Public License, -if you distribute this file as part of a program or library that -is built using GNU libtool, you may include it under the same -distribution terms that you use for the rest of that program. - -This library is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Pdsh can run independently of the RMS product (the -'rms' kernel module, which is used by pdsh, is a distinct facility from -the RMS product). - -Quadrics has provided a PDSH FAQ which may answer some common questions -about getting the qshell module to run MPI jobs. Please see - - http://web1.quadrics.com/twiki/bin/view/FAQs/SetupPDSH - - -rms pdsh module ---------------------------------------- -Pdsh can also be run via the Quadrics RMS 'allocate' command such that -allocate takes care of the node reservations and passes a batch ID through -to pdsh via the RMS_RESOURCEID environment variable. Pdsh retrieves -the list of allocated nodes out of the RMS database using the rmsquery -command. This functionality is provided by the "rms" pdsh module -(--with-rms). - -slurm pdsh module ---------------------------------------- -Similar to the rms pdsh module, the slurm module allows pdsh to target -nodes based on SLURM allocations, either targetting an already running job -or by running under ``srun --allocate'' The SLURM jobid can be passed to -pdsh using the `-j' option provided by the module, or via the SLURM_JOBID -environment variable, which is set by --allocate. - - -The `/etc/elanhosts' config file ---------------------------------------- -Pdsh uses a simple config file, /etc/elanhosts, to describe hosts -containing Elan adapters (and on which Elan MPI jobs may be run). The -config file is also used by the daemons qshd and mqshd to initialize -the Elan network error resolver thread. Parsing of the /etc/elanhosts -file is accomplished by using the libelanhosts(3) library, upon which -pdsh depends (when building for QsNet).
