* [svn-r12149] Purpose:James Laird2006-03-231-7/+1
| | | | | | | | | | | | | | | | Bug fix Description: Previous checkin did a bad thing; 'make clean' failed in example directories. Solution: Fixed commence.am so that examples no longer break, and fixed a mistake in conclude.am. Platforms tested: heping (minor makefile change) Misc. update:
* [svn-r12143] Purpose:James Laird2006-03-231-0/+4
| | | | | | | | | | | | | | Bug fix Description: make check-clean didn't clean results of example tests Solution: Fixed Makefiles so that check-clean recurses into example directories. Also a little Makefile cleanup. Platforms tested: mir, modi4, heping, copper
* [svn-r11891] Purpose: Small bug fixElena Pourmal2006-01-251-1/+3
| | | | | | | | | | | | | | | | Description: h5_group example didn't work on VMS; it turned out that a group was not closed and since the default file close degree is "weak", file was not closed either. When program attempted to open the same file, system reported an error since the file was "locked by another user". UNIX systems apperently do not care and open the same file without any problem. Solution: Added H5Gclose calls. Platforms tested: VMS server and heping Misc. update:
* [svn-r11780] Purpose:James Laird2005-12-092-86/+44
| | | | | | | | | | | | | | | | | Added high-level example directories Description: Refactored common code out of examples Makefiles.am, added high-level example directories, added packet table examples. Solution: Examples now draw from a common config/examples.am file, which contains rules for installing, uninstalling, and cleaning examples. High-level example directories are mostly empty, except for the C and C++ packet table tests. Platforms tested: mir, sleipnir, copper, shanti
* [svn-r11741] Purpose:James Laird2005-11-181-6/+16
| | | | | | | | | | | | | | | | | Bug fix Description: Fortran type generation was broken in two ways. Fixed both. Solution: Firstly, there were a couple of path problems. Fixed a typo and specified the full path of a file. Secondly, the dependencies weren't right when building with HDF5-specific commands (make lib, make check-s, etc.). Tweaked dependencies to fix the problem. Platforms tested: mir, modi4, sleipnir
* [svn-r11738] Purpose:James Laird2005-11-181-0/+4
| | | | | | | | | | | | | | | | | | | Configure feature Description: Added 'make trace' target. Solution: Added tracing to 1.7. This was done automatically in 1.6, but left out of 1.7 until now (oops!). Tracing in 1.7 only happens manually, when the user types 'make trace.' Tracing automatically requires more framework than it's worth. I also fixed a couple of tracing bugs and ran trace. Platforms tested: mir, sleipnir, modi4 Misc. update:
* [svn-r11737] Purpose:James Laird2005-11-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix Description: Before this checkin, 'gmake check-s' would fail if there was a file in the current directory named 'check-s'. This is fixed under gmake (not sure how to fix for other makes). Solution: check, progs, install, etc. are what gmake calls "phony" targets, which means that no file should be created. These targets can be specified by a line of the form .PHONY: check progs install ... Automake adds this line for targets it knows about, but HDF5 has a lot of custom rules. This checkin adds a .PHONY line for those rules. I believe that only gmake recognizes the .PHONY line (at least, pmake doesn't seem to), but a partial solution is better than none. This error should occur very rarely anyway (the user has to manually create files with names like 'build-check-s' or '_test'). Platforms tested: mir, sleipnir, modi4
* [svn-r11712] Purpose:Quincey Koziol2005-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New feature Description: Check in baseline for compact group revisions, which radically revises the source code for managing groups and object headers. WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! This initiates the "unstable" phase of the 1.7.x branch, leading up to the 1.8.0 release. Please test this code, but do _NOT_ keep files created with it - the format will change again before the release and you will not be able to read your old files!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! WARNING!!!! Solution: There's too many changes to really describe them all, but some of them include: - Stop abusing the H5G_entry_t structure and split it into two separate structures for non-symbol table node use within the library: H5O_loc_t for object locations in a file and H5G_name_t to store the path to an opened object. H5G_entry_t is now only used for storing symbol table entries on disk. - Retire H5G_namei() in favor of a more general mechanism for traversing group paths and issuing callbacks on objects located. This gets us out of the business of hacking H5G_namei() for new features, generally. - Revised H5O* routines to take a H5O_loc_t instead of H5G_entry_t - Lots more... Platforms tested: h5committested and maybe another dozen configurations.... :-)
* [svn-r11646] Purpose:James Laird2005-10-311-4/+14
| | | | | | | | | | | | | | | | | | Bug fix/feature Description: Added support for -shlib in h5fc and h5c++. Made check-install use -shlib when only shared libraries have been installed. Solution: h5fc and h5c++ didn't recognize -shlib. Stole code from h5cc to link against shared libraries. When static libraries are disabled, the examples Makefiles will automatically use the -shlib option to link against shared libraries. Thus, --disable-static and make check-install should work together. Platforms tested: heping(disable-static, enable-static, fortran, c++), modi4 (disable-static, fortran, c++, parallel, enable-static)

| | | | | | | | | | | | Bug fix Description: Removed detection of pdb from configure.in as a corollary to removal of pdb2hdf5 tool. Platforms tested: mir, modi4
* [svn-r11573] Purpose:James Laird2005-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | Bug fix Description: Changed configure.in to use an environment variable TR to set the path to the tr utility. Solution: There are two kind of tr on Solaris with slightly different syntax. HDF5's configure relies on the "standard" tr. Traditionally, HDF5ers have needed to make sure that the "right" tr was found before the wrong one in their path; now they can use an environment variable. Platforms tested: mir, shanti, sol Misc. update: Forgot to update release notes. Off to do that now.
* [svn-r11566] Purpose:James Laird2005-10-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Makefile bug fix Description: Previously, automake didn't output rules to build perform/mpi-perf or the test/gen_* programs. Now these can be built by typing 'make mpi-perf' (or 'make foo') or by configuring with --enable-build-all. Solution: Automake doesn't like having rules for programs it doesn't build. Tricked it by having these programs built "sometimes"--whenever the user enables --build-all. This should be used mostly for testing and to ensure that these helper programs compile. ***IMPORTANT*** These programs do *not* currently compile. When --enable-build-all is used (not the default), gen_new_fill fails because it uses an old API. This is an existing "bug" that has simply been exposed by this checkin. Platforms tested: sleipnir, modi4, sol Misc. update:
* [svn-r11478] Purpose:Albert Cheng2005-09-291-8/+7
| | | | | | | | | | | | | | | | bug fix. Description: When a parallel test script test fails, make would continue because the way it was setup inside a for loop. Fixed it by issuing an exit 1 inside the loop. There was also a typo error in the newer command comparision that it must be $${chkname} in order to be valid. Also, the test script itself was not checked in the newer lists. All fixed. Platforms tested: h5committested and also hand tested in heping pp mode.
* [svn-r11470] Purpose:John Mainzer2005-09-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair synchronization bug in the metadata cache in PHDF5 Also repair numerous other bugs that surfaced in testing the bug fix. Description: While operations modifying metadata must be collective, we allow independant reads. This allows metadata caches on different processes to adjust to different sizes, and to place the entries on their dirty lists in different orders. Since only process 0 actually writes metadata to disk (all other processes thought they did, but the writes were discarded on the theory that they had to be collective), this made it possible for another process to modify metadata, flush it, and then read it back in in its original form (pre-modification) form. The possibilities for file corruption should be obvious. Solution: Make the policy that only process 0 can write to file explicit, and visible to the metadata caches. Thus only process 0 may flush dirty entries -- all other caches must retain dirty entries until they are informed by process 0 that the entries are clean. Synchronization is handled by counting the bytes of dirty cache entries created, and then synching up between the caches whenever the sum exceeds an (eventually user specified) limit. Dirty metadata creation is consistent across all processes because all operations modifying metadata must be collective. This change uncovered may bugs which are repaired in this checkin. It also required modification of H5HL and H5O to allocate file space on insertion rather than on flush from cache. Platforms tested: H5committest, heping(parallel & serial) Misc. update:
* [svn-r11446] Purpose:James Laird2005-09-201-2/+3
| | | | | | | | | | | Bug fix Description: Massaged the newer script and config/conclude.am to make SX6 happy. Platforms tested: SX6, sol, mir
* [svn-r11431] Purpose:Albert Cheng2005-09-181-2/+3
| | | | | | | | | | | | | | | | | New feature. Description: Added the time command to the make check target to report time usage of the execute of each test and test scripts. This gives us some idea how long each test takes and some vague idea it is compute bound or not. powerpc-ibm-aix5.x: Change $RUNPARALLEL default setting to allow it being invoked by the time command. Platforms tested: h5committested.
* [svn-r11421] Purpose:James Laird2005-09-161-4/+11
| | | | | | | | | | | | | | | Feature Description: Added H5_CFLAGS, etc. to 1.7 branch. Now compilation flags can be put in H5_*FLAGS and they'll be used when building hdf5 but not in h5cc. Platforms tested: mir, sleipnir, modi4 Misc. update:
* [svn-r11420] Purpose:James Laird2005-09-161-0/+2
| | | | | | | | | | | | | | | | | Bug fix Description: Disabled C++ shared libraries for Sun Workshop compiler. Solution: This bug only seems to happen when using the -xarch=v9 flag to compile in 64-bit mode, but disabling shared libraries entirely for this compiler is an easier fix (I don't know how to detect 64 bit mode from the command line). The framework for disabling shared libraries for other C++ compilers is in place. Platforms tested: sol, mir, sleipnir, modi4
* [svn-r11418] Purpose:James Laird2005-09-151-0/+2
| | | | | | | | | | | | | | | | Bug fix/feature Description: Disabled shared libraries for a number of Fortran compilers that don't support them. This allows other compilers to support shared Fortran libraries. Solution: Added a conditional, SHARED_FORTRAN_CONDITIONAL, which is true if Fortran supports shared libraries. It is set in configure.in. Platforms tested: mir, sleipnir, colonelk, heping
* [svn-r11381] Purpose:Albert Cheng2005-09-091-1/+1
| | | | | | | | | | | | | | | | | | | bug fix. Description: In Janus (Tflops), the test would seg-fault in production (compiled with -O). If compiled with -O0, it would be okay. Track down the problem to the for loop index i & j being declared with type hsize_t which is usually unsigned long int. Guess the Tflop compiler has a bug in optimization that could not handle unsigned int as for loop index. Solution: Since it is no need for i & j to be hsize_t and it makes more sense to have them with type int. Changed them to int type. Platforms tested: Passed in tflops and colonelk here.
* [svn-r11323] Purpose:Albert Cheng2005-08-312-3/+4
| | | | | | | | | | | | | | | | tidy up. Description: MPE option created *.clog file whenever it is executed in MPI. The cleanup of *.clog files were done in individual Makefile.in. Often, it is forgotten. Solution: Moved the cleaning of *.clog files to CHECK_CLEANFILES in commence.am so that it is applied whenever check-clean is called. Platforms tested: heping pp using MPE.
* [svn-r11319] Purpose:James Laird2005-08-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Bug fixes Description: This checkin fixes an occasional error on kelgia on sol during distclean. It also causes test scripts to depend properly on the programs they're supposed to be testing. Solution: The kelgia bug was due to some files being cleaned by automake and manually. Removed the manual cleaning in src/Makefile.am. Test script dependencies now need to be specified manually, since the makefile can't guess what they test from their name. Currently all test scripts in a given directory have a single list of dependencies--this was easy and seems to be sufficient. These dependencies are listed in the SCRIPT_DEPEND variable in the Makefile.am. Platforms tested: heping, mir, modi4, sol Misc. update:
* [svn-r11303] Purpose:Albert Cheng2005-08-261-23/+15
| | | | | | | | | | | | minor tidy up. Description: Changed both test programs and test scripts to use the same suffixes (.chkexe and .chklog). Changed from .log to .chklog to avoid running into potential conflicts by other "things" (e.g., config.log). Tested: Heping.
* [svn-r11245] Purpose:Quincey Koziol2005-08-1313-401/+401
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r11213] Purpose:Albert Cheng2005-08-081-7/+2
| | | | | | | | | | | | | | | | | | | Bug fix and improvement. Description: The test output were not displayed for parallel tests. The serial tests output were always displayed whether the test was actually ran this time or not. Solution: Moved the display of test output inside the target where the actual tests are run. Platforms tested: Tested in heping using pp and fortran.
* [svn-r11207] Purpose:Albert Cheng2005-08-081-55/+63
| | | | | | | | | | | | | | | | | | | | | Bug fix and code minor cleanup. Description: The attempt to redirect stderr together to the log files were done in the wrong order such that stderr output goes to where stdout WAS. Fixed that. Code minor cleanup--use shell variables to hold the name of the log file and the test instead of generating them repeatedly. This makes easier code reading, less crowded and avoid typos. Only conclude.in is changed. The Makefile.in changes are all derived from automake. Platforms tested: h5committested. Misc. update:
* [svn-r11185] Purpose:James Laird2005-08-022-13/+17
| | | | | | | | | | | | | | | Makefile feature Description: 'make check-clean' now cleans *.h5 files created by tests as well as .log and .chkexe files. Solution: check-clean is now a separate target in its own right, which cleans less than mostlyclean (check-clean < mostlyclean < clean < distclean). Platforms tested: mir, heping, modi4 (serial and parallel)
* [svn-r11179] Purpose:James Laird2005-08-012-16/+23
| | | | | | | | | | | | | | | | | | | Feature: check-clean target Description: 'make check-clean' cleans up output files from tests. Solution: Tests create foo.chkexe and foo.log files. Scripts create foo.chksh and foo.logsh files. 'make check-clean' will clean these files up so that the tests can be re-run. Also suppressed some not-very-useful output of Makefiles when it would echo commands. Platforms tested: mir, sleipnir, modi4 Misc. update:
* [svn-r11095] Purpose:James Laird2005-07-211-15/+53
| | | | | | | | | | | | | | | | | | | | | | Configuration feature Description: Serial test output is now stored in log files and printed when all tests in a directory complete, or when a test fails. This should make test output more readable and useful. Also made changes to clean up ii_files directories that are created by some C++ compilers/linkers. Also fixed a few minor Makefile bugs. Solution: When serial tests run, their output is saved in *.log or *.logsh. While running, tests only print when they begin and when they complete; their more specific output (from the log file) is printed if the test fails or when all tests have completed. Comments welcome. Platforms tested: mir, modi4 (parallel and serial), copper, shanti
* [svn-r11083] Purpose:James Laird2005-07-182-10/+8
| | | | | | | | | | | | Bug fixes Description: A number of minor changes to Makefiles. Some files will now be cleaned properly, some comments are more informative, etc. Platforms tested: heping, mir, modi4
* [svn-r11042] Purpose:Quincey Koziol2005-07-071-7/+7
| | | | | | | | | | | | | | | | | | Bug fix Description: The ".chksh" file for a test script was being created in the "source" location rather than the build location. This can cause problems when multiple builds are running because "slower" machines will see the ".cshsh" file from faster machines and will not run the test script as they should. Solution: Use 'basename' command to strip off the path of the script and create the ".chksh" file in the build location. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest
* [svn-r11034] Purpose:Albert Cheng2005-07-071-4/+2
| | | | | | | | | | | | | | | | | bug fix. Description: -nt is not a universal option for the test command in all platforms. The use of it in conclude.am cause some platforms to bark at the Makefile generated. Solution: Created a command script bin/newer which tests if file1 is newer than file2. Replace the "test file1 -nt file2" by "newer file1 file2". Platforms tested: Tested in sol.
* [svn-r11016] Purpose:James Laird2005-07-042-0/+8
| | | | | | | | | | | | | | | | Bug fix Description: Added dependencies to examples Makefiles so that examples can be run in parallel. Solution: The examples directories (for C, C++, and Fortran) all have some dependencies explicitly spelled out in their Makefiles.am. This is a good short-term solution, and should prevent errors in the Daily Tests. Platforms tested: mir, modi4 (parallel and sequential)
* [svn-r11013] Purpose:James Laird2005-07-011-7/+7
| | | | | | | | | | | | | | | | | | Bug fix Description: Fixed bugs that caused tests to be unable to find testhdf5.sh during daily tests, and another that broke sol and shanti. Solution: When tests are run, their path is ./$testname . When scripts are run, their path has no leading "./". Fixed. Sol and shanti don't recognize the -e option for test, but they do know -f. Fixed. Also modified release notes. Platforms tested: mir, shanti, heping
* [svn-r11008] Purpose:James Laird2005-06-301-87/+81
| | | | | | | | | | | | | | | | | | | | | | Feature: tests now use parallel make and only run once Description: When make is invoked in parallel (using the -j option), several tests will now be run simultaneously. This should speed up testing on a number of systems. When a test passes, it creates a foo.chkexe or foo.chksh file, which prevents the test from running again unless the test or library changes. Solution: Most of the changes live in config/conclude.am. Added *.chkexe and *.chksh files to the list of files to be cleaned at "make mostlyclean" time. Parallel tests still run one at a time, but use the same make instructions as serial tests. Platforms tested: mir, eirene, sleipnir, pommier, copper, modi4 (some errors occurred, probably due to the test being run before updating hdf5. Will re-run tests after checkin.)
* [svn-r10858] Purpose:Albert Cheng2005-06-041-4/+15
| | | | | | | | | | | bug fix. Description: The check-s and check-p targets are not recursively passes down. Make them so. Platforms tested: heping (serial and pp).
* [svn-r10849] Purpose:Albert Cheng2005-06-021-1/+3
| | | | | | | | | | | | | | | | | | bug fix Description: check-s and check-p were set as pre-requistics of test. They would get executed in parallel if parallel make is used. This could cause problems since serial tests are used to be executed before parallel tests. It is not known if it is always okay to run serial and parallel tests in simultantously. Solution: Change check-s and check-p as actions of the target test so that they get executed sequnentially. Platforms tested: heping PP.
* [svn-r10840] Purpose:James Laird2005-06-021-6/+36
| | | | | | | | | | | Added check-s and check-p targets. Description: Added check-s and check-p targets to 1.7 branch to match changes to 1.6 branch. Now parallel and serial tests can be run separately. Platforms tested: mir, modi4, copper
* [svn-r10570] Purpose: MaintenanceElena Pourmal2005-04-071-4/+0
| | | | | | | | | | | Description: Removed support for SRB driver Solution: Removed or modified appropriate files; ran reconfigure to regenerate Makefile.in and configure files. Platforms tested: heping and shanti Misc. update: ran bin/chkmanifest on heping
* [svn-r10534] Purpose:James Laird2005-04-041-0/+1
| | | | | | | | | | | | | | | | | | | | Configuration feature Description: Different Fortran compilers mangle function names in different ways (upper case, lower case, adding underscores). To link between Fortran and C functions, we need to know what a given function's name is under a given compiler. Solution: Use autoconf's FC_WRAPPERS check to determine the Fortran naming scheme and define the FC_FUNC_ macro to name our functions (in H5f90proto.h). Removed references to our old FNAME macro, as well as flags that indicated whether function names were upper or lower case. Platforms tested: mir, pommier, modi4, copper, more
* [svn-r10517] Purpose:James Laird2005-03-311-6/+15
| | | | | | | | | | | | | | | | Bug fix Description: On some machines, $RUNSERIAL variable needs to be used to run tests. Set $RUNTESTS (which is used for non-parallel tests) to be $RUNSERIAL in configure.am. Also, since I was updating all Makefiles.in anyway, I updated commence.am to point to autotools installs in AFS instead of those on heping. Platforms tested: mir, sleipnir, modi4, copper
* [svn-r10511] James Laird2005-03-301-1/+6
| | | | | | | | | | | | | Purpose: "Bug fix" Description: Hardcoded Makefiles to use /bin/sh instead of letting configure detect shell automatically. This is what v1.6 does, and avoids problems on janus. Platforms tested: sleipnir, copper, modi4, mir
* [svn-r10475] Purpose:James Laird2005-03-291-0/+2
| | | | | | | | | | | | | | | | | Feature - conditional compilation Description: SRB file driver and tests are now compiled only when SRB is enabled (using --with-srb during configure). Solution: Added an automake conditional in configure.in, altered Makefiles.am in src and test directories to depend on that conditional. This should make a nice example for posterity to add conditionally compiled sources. Platforms tested: heping (only configure change)
* [svn-r10459] James Laird2005-03-281-0/+1
| | | | | | | | | | | | | | | | | Purpose: Added C++ wrapper for Packet Table API. Description: Added macro for high-level C++ library (LIBH5CPP_HL), which changes every Makefile.in. Added directories for high-level C++ library (though currently only Packet Table API is supported). Added both C++ source and tests. Platforms tested: sleipnir, mir, modi4 Misc. update:
* [svn-r10158] Purpose:James Laird2005-03-071-76/+175
| | | | | | | | | | | | | | | | | | | | | | Automake version upgrade Description: Upgraded automake version from 1.6.2 to 1.9.5. Changed bin/reconfigure script to use automake 1.9.5. Changed configure.in and Makefiles to use new FCFLAGS and FC variables instead of FFLAGS and F9X. Automake and configure should now do the lion's share of the work supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will be cleaned later). Altered how configure handles pmake; now root-level Makefile.in is processed by bin/reconfigure to have a .MAKEFLAGS target, since automake no longer allows us to define unused variables. Configure now always checks for C++ compiler even if it is not used, since automake thinks this is the Right Thing To Do and will break otherwise. Platforms tested: Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.

| | | | | | | | | | | | | | | | | | | Purpose: Bug fix Description: modi4 dies during build with strange errors. The root cause of these is a two-year-old hack in HDF5's libtool script that only takes effect on IRIX. Solution: Edited the libtool hack (by editing ltmain.sh) to correct a bug in the hack. Also made sure that compiler-specific DEFAULT_LIBS are used when linking. Platforms tested: sleipnir, copper, modi4, sol
