A second beta release of BLCR 0.5.0 is now available at http://mantis.lbl.gov/blcr-dist Here are the changes since last week's first beta: - Add support for 2.6.18 though 19 - Add support for 2.4.30 through 2.4.34 - Support for directories opened with opendir() - Fix bugs found in testing, or in previous snapshots, including: + Bug 1807: unrecognized warning suppression flag passed to gcc + Bug 1854: libcr link failure w/ stack-protection-enabled gcc + Incorrect treatment of certain anonymous mmap() cases + Problems w/ multilib support in the rpm specfile Below is the full NEWS entry, relative to the Nov. 2005 0.4.2 release. I am still hoping to get user feedback on a proposed fix to bug 1925 (see http://mantis.lbl.gov/bugzilla/show_bug.cgi?id=1925 ) for inclusion in 0.5.0. If I can get confirmation that the fix works in the next few days, then I'll issue a 0.5.0_b3 for wider testing. This will become 0.5.0 in 7 days, unless significant new bugs are reported or a resolution is reached for bug 1925 before then. -Paul PS You are receiving this either because you are on the checkpoint_at_lbl_dot_gov list, or because you've recently sent email to the list (or me directly) asking about BLCR status. 0.5.0_b2 -------- February 12, 2007 Functionality and expanded-support release. - Expanded kernel coverage + 2.6.0 through 2.6.19 for x86 and x86_64 + 2.4.0 through 2.4.34 for x86 only - Multi-process support (related processes and associated pipes) + See BLCR_Users_Guide.html and the cr_checkpoint man page - Support for 32-bit apps on 64-bit kernels + See "--enable-multilib" in BLCR_Admin_Guide.html - Support for directories opened with opendir() - Support for checkpoints on Luster file systems + Contributed by Dean Luick <luick_at_cray_dot_com> - Support for building static libcr + Contributed by Dean Luick <luick_at_cray_dot_com> - Fixes to many distclean problems + Issues identified by Dean Luick <luick_at_cray_dot_com> - I/O aggregation for improved performance + Contributed by Qi Gao <[email protected]> - Additional examples and test cases - API addition: cr_get_restart_info() - "Retool" of configure code for ease of addition/maintenance - Numerous bug fixes, including: + Bug 1640: context files > 2GB require O_LARGEFILE + Bug 1662: context files open R/W leads to restart failure + Bug 1669: checkpoint to a socket fails + Bug 1807: unrecognized warning suppression flag passed to gcc + Bug 1854: libcr link failure w/ stack-protection-enabled gcc + Incorrect treatment of certain anonymous mmap() cases + Wrong parent for restored orphans (children of init) + dup()ed file descriptors always restored together -- Paul H.
