|---|
| 218 | changed from using individual DB objects for each handle, to one |
|---|
| 219 | DB object for all keyval entries. This affects the storage format, |

|---|
| 252 | window size to be changed dynamically. Use a pipe file descriptor |
|---|
| 253 | for poll to prevent stalls. Reorganize epoll to add and remove epoll |
|---|
| 254 | watches. |
|---|
| 255 | - pvfs2-genconfig now supports --iospec and --metaspec options. Also fixed |
|---|
| 256 | some hostname sorting and range spec bugs. |
|---|
| 257 | - pvfs2-client: added --logstamp. nonblocking statfs and mount support. |
|---|
| 258 | - handle allocation wasn't resulting in a uniform distribution. Now we |
|---|
| 259 | pick a server at random and then select the remaining handles in a |
|---|
| 260 | round-robin fashion |

| 261 | - pvfs2-ping does better per-server error reporting and keeps track of errors |
|---|
| 262 | better |

| 374 | pvfs2-1.2.0 |
|---|
| 375 | =============== |
|---|
| 376 | - make server better able to handle bogus file names (David Metheny) |
|---|
| 377 | - better casts for ppc64 |
|---|
| 378 | - even better configure tests for various berkely db features |
|---|
| 379 | - documentation updates for Fedora 4 changes |
|---|
| 380 | - extended attribute support (not available through VFS yet) |
|---|
| 381 | - nightly build infrastructure now mostly in place |
|---|
| 382 | - --enable-strict now works again |
|---|
| 383 | - new utilities: pvfs2-touch, pvfs2-stat, pvfs2-ln |
|---|
| 384 | - add additional write() checks to kernel module |
|---|
| 385 | - hold st_nlink field at 1: keeping a true count is quite hard to do |
|---|
| 386 | correctly in a distributed environment |
|---|
| 387 | - new distribution: "varstrip"j |
|---|
| 388 | - better pvfs2 kernel module debugging interface (/proc/sys/pvfs2/debug) |
|---|
| 389 | - pvfs2 now supports setgid |
|---|
| 390 | - build: avoid some warnings from gcc4 |
|---|
| 391 | - kernel: understand new backing_dev_info format in 2.6.12 |
|---|
| 392 | - Added DefaultNumDFiles as filesystem config option. |
|---|
| 393 | - Added num_dfiles tabfile option. i |
|---|
| 394 | The number of dfiles is set by searching for the first given hint in this |
|---|
| 395 | order: application hints, tabfile, server config. The selected |
|---|
| 396 | distribution may modify the hint if neccesary. |
|---|
| 397 | - Phil Carns contributed general improvements and bug fixes for the dotconf |
|---|
| 398 | parser. |
|---|
| 399 | - Added DefaultDistribution section support for server config file. Section |
|---|
| 400 | is optional and accepts Name, Param, and Value (Param and Value may be |
|---|
| 401 | repeated multiple times in the section). |
|---|
| 402 | - added 'retry' and 'timeout' config file options |
|---|
| 403 | - will consult /etc/mtab as an additional source for pvfs2 tabfile entries |
|---|
| 404 | |
|---|
| 405 | pvfs2-1.1.0 |
|---|
| 406 | =============== |
|---|
| 407 | - network protocol: more 64-bit alignment fixes |
|---|
| 408 | - build: hide karma details in its module.mk |
|---|
| 409 | - build: remove duplicate commands used for QUIET_COMPILE |
|---|
| 410 | - build: fix test configure library detection |
|---|
| 411 | - build: simplify karma and vis some more |
|---|
| 412 | - build: add tests for features of Berkeley DB 4.3.xx |
|---|
| 413 | - trove: fix bugs introduced by new features of DB 4.3.xx |
|---|
| 414 | - docs: added doxygen configuration file and doxygen-style docs |
|---|
| 415 | to many source files |
|---|
| 416 | - pvfs2-cp: can pass strip size as a parameter (thanks David Beilloin |
|---|
| 417 | <dbeilloi@mc.com>) |
|---|
| 418 | - gossip: avoid double-timestamp in debug and error messages |
|---|
| 419 | - feature-test for kernel routines i_size_write, i_size_read, and parent_ino |
|---|
| 420 | - recover better from server failures |
|---|
| 421 | - kernel: export superblock magic number for romio autodetection |
|---|
| 422 | - 64-bit: change some protocol encodings to avoid unaligned accesses, fix |
|---|
| 423 | server crash |
|---|
| 424 | - documentation updates |
|---|
| 425 | - Phil Carns and David Beilloin reported various memory leaks and memory |
|---|
| 426 | misuse throughout the code |
|---|
| 427 | - Phil Carns and David Metheny contributed their improvment to the |
|---|
| 428 | permissions-checking routines. Secondary groups work much better now. |
|---|
| 429 | - configure-time options to select behavior needed on redhat-like environments |
|---|
| 430 | - can disable server support at configure time |
|---|
| 431 | - various tweaks to make cross compiling easier |
|---|
| 432 | - Phil Carns contributed a new config file option (LogStamp) to select |
|---|
| 433 | timestamp format |
|---|
| 434 | - By default we sync metadata (TroveSyncMeta yes) and not data (TroveSyncData |
|---|
| 435 | no). This configuration is a good compromise between reliability and |
|---|
| 436 | performance for most workloads. |
|---|
| 437 | - Joachim Worringen's noncontig benchmark turned up several bugs now addressed |
|---|
| 438 | in this release |
|---|
| 439 | - bugfix where pvfs2-chmod would cause all future operations to fail |
|---|
| 440 | - bugfix for 64 bit servers. pvfs2 on opteron now passes the bonnie benchmark |
|---|
| 441 | |
|---|
| 442 | pvfs2-1.0.1 |
|---|
| 443 | =========== |
|---|
| 444 | - ib: add configure-time checks for mosal library variations |
|---|
| 445 | - ib: flush send queue work requests periodically |
|---|
| 446 | - ib: search receive queue for both eager and rts (D. Beilloin) |
|---|
| 447 | - improved support for some cases of file holes (that require zero fill) |
|---|
| 448 | - fixed a crash bug due to incorrect assertion regarding zero fill |
|---|
| 449 | - applied annotations and cleanups to the kernel module in response to |
|---|
| 450 | using the automated correctness checker called 'sparse' |
|---|
| 451 | - fixed a bug that did not properly allow storage space removals when |
|---|
| 452 | using ReiserFS as the underlying file system |
|---|
| 453 | - added more redhat checks for determining if we need to patch the |
|---|
| 454 | kernel module code to work properly with particular releases |
|---|
| 455 | - FAQ documentation update |
|---|
| 456 | |
|---|
| 457 | |
|---|
| 458 | pvfs2-1.0.0 |
|---|
| 459 | =========== |
|---|
| 460 | - disabled mmap readahead cache by default; allow configure option to |
|---|
| 461 | optionally enable it |
|---|
| 462 | - added support for handling several cases of file hole zero fills |
|---|
| 463 | (i.e. sparse files) |
|---|
| 464 | - configured acache timeout to be 5 seconds by default through the |
|---|
| 465 | vfs; sysint was already 5 seconds |
|---|
| 466 | - added karma program installation to make install target |
|---|
| 467 | - redhat 9 related changes (in order to work out of the box) |
|---|
| 468 | - used some 2.6.x kernel code on redhat 9 2.4.x kernels, if detected |
|---|
| 469 | - no longer mark pages as reserved on redhat 9 2.4.x kernels, as it |
|---|
| 470 | causes an oops on their kernel (i.e. not necessary) |
|---|
| 471 | - installed a wrapper script in place of the pvfs2-server that |
|---|
| 472 | exports the LD_ASSUME_KERNEL environment variable before running |
|---|
| 473 | the server(to avoid using the redhat NPTL library which is |
|---|
| 474 | incompatible) |
|---|
| 475 | - fixed make kmod{24}_install even if there are multiple UTS_RELEASE |
|---|
| 476 | definitions in the version.h file (as there are in redhat 9) |
|---|
| 477 | |
|---|
| 478 | |
|---|
| 479 | pvfs2-0.9.0 |
|---|
| 480 | =========== |
|---|
| 481 | - documentation updates to HA and FAQ documents |
|---|
| 482 | - better balancing (randomization) of data server selection when |
|---|
| 483 | creating new files |
|---|
| 484 | - clean up a few request-related 8-byte alignment issues for alpha |
|---|
| 485 | - fixed an AMD64 kernel oops due to a bad cast |
|---|
| 486 | - cleaned up error code types in the exposed sysint and mgmt methods |
|---|
| 487 | (using PVFS_error rather than int) |
|---|
| 488 | - added a setattr debugging mask and changed most detailed setattr |
|---|
| 489 | debugging to use it |
|---|
| 490 | - added a mkdir debugging mask and changed most detailed mkdir |
|---|
| 491 | debugging to use it |
|---|
| 492 | - added some inlined methods in PVFS_util (as they need to be used on |
|---|
| 493 | both the server and the client) for getting the current time in |
|---|
| 494 | PVFS_time format, encoding a PVFS_time as a version (finer grained |
|---|
| 495 | than a 'normal' PVFS_time since we can use the high 32 bits), and |
|---|
| 496 | decoding the version as a PVFS_time |
|---|
| 497 | - added a compatibility hack that _should_ allow no noticeable |
|---|
| 498 | breakage on existing storage space, but will eventually migrate to |
|---|
| 499 | the slightly new storage format over time |
|---|
| 500 | - modified client side sys-mkdir, sys-create, and sys-symlink to |
|---|
| 501 | encode the mtime as a version when passing it to the server (so it's |
|---|
| 502 | transparent from the server perspective) |
|---|
| 503 | - modified server side get-attr to decode the version read from disk |
|---|
| 504 | back into an mtime (so it's transparent from the client perspective) |
|---|
| 505 | - modified mkspace method to properly version newly created root and |
|---|
| 506 | lost+found directories |
|---|
| 507 | - modified the server side mkdir operation to return -PVFS_EINVAL if |
|---|
| 508 | the object attr type is not a directory object |
|---|
| 509 | - vfs readdir modifications to detect directory version changes on |
|---|
| 510 | listings; default behaviour is unchanged |
|---|
| 511 | - fixed bug in collection remove that didn't remove the collection |
|---|
| 512 | information from the collection db (which manifested as having a bug |
|---|
| 513 | where a collection that was once created and then removed could |
|---|
| 514 | never be created again due to a lookup succeeding before it should) |
|---|
| 515 | - added documentation on how to create multiple file systems within a |
|---|
| 516 | single pvfs2 storage space |
|---|
| 517 | - added documentation on return codes of the sysint methods |
|---|
| 518 | - pvfs2-mkspace improvements: |
|---|
| 519 | - now requires a collection ID, storage space and a handle range |
|---|
| 520 | - fixed types used to represent actual root handle and collection id |
|---|
| 521 | to be the proper types, rather than integers |
|---|
| 522 | - remove many defaults in favor of requiring cmdline options |
|---|
| 523 | - replace atoi calls with strtou{l}l to accomodate larger values if |
|---|
| 524 | specified |
|---|
| 525 | - cosmetic output improvements |
|---|
| 526 | - fixed mkspace method to make sure that we only use handle ranges |
|---|
| 527 | that are both non-null, AND are not an empty string |
|---|
| 528 | |
|---|
| 529 | |
|---|
| 530 | pvfs2-0.8.0 |
|---|
| 531 | =========== |
|---|
| 532 | - adjusted mask values for event logging to skip 0 mask |
|---|
| 533 | - moved handle counting in statfs to server side so that it is |
|---|
| 534 | done in parallel |
|---|
| 535 | - replaced uniq() subroutine in PAV to avoid recursion |
|---|
| 536 | - pvfs2-statfs cleanups and cast fixing |
|---|
| 537 | - pvfs2-shell-test: replaced a directory test |
|---|
| 538 | - add a clientcore_timing debug mask that only logs the operation |
|---|
| 539 | timings from the pvfs2-client-core |
|---|
| 540 | - added some pts debugging |
|---|
| 541 | - fixed bad assumption in getattr-acache that might have looked at the |
|---|
| 542 | wrong handle/fs_id during some operations (e.g. lookup) |
|---|
| 543 | - removed potential latency on system startup by trying to store temp |
|---|
| 544 | config files in /tmp/ first rather than the current dir |
|---|
| 545 | - make sure that our error routines strip any known class error bits |
|---|
| 546 | instead of deciding that they're unrecognized if set |
|---|
| 547 | - improved trove error handling |
|---|
| 548 | - improved pvfs2-server error handling |
|---|
| 549 | - fixed crash bug in our config parser that tried to strdup strings |
|---|
| 550 | that might be NULL |
|---|
| 551 | - pvfs2-types.h header file simplification and cleanups |
|---|
| 552 | - extended buffer size of filename for use with mkstemp as it started |
|---|
| 553 | failing on ppc with misc unexpected characters |
|---|
| 554 | - addition of a simple vfs test program that creates a file with a |
|---|
| 555 | hole in it and tries to read from that hole (this demonstrates a |
|---|
| 556 | currently known bug) |
|---|
| 557 | - addition of the same test program using only the system interface |
|---|
| 558 | - fixed some misc memory/resource leaks |
|---|
| 559 | - fixed test program ls.c and admin program pvfs2-ls.c to not issue an |
|---|
| 560 | extra call to readdir on every run by fixing a slight logic bug |
|---|
| 561 | - added a directory version that is passed back from the server to the |
|---|
| 562 | client on each successful readdir call and updated the client and |
|---|
| 563 | server response structures and encoder to accomodate this |
|---|
| 564 | - ncache related: |
|---|
| 565 | - increased ncache timeout from 5 seconds to 30 seconds by default, |
|---|
| 566 | but keep it disabled by default (it's still experimental) |
|---|
| 567 | - cleaned up the ncache and make it useable by the |
|---|
| 568 | lookup/remove/create/mkdir/etc calls (if enabled) |
|---|
| 569 | - added a flag to the client sysint lookup sm that records if the |
|---|
| 570 | final object resolved was a followed symlink or not (regardless of |
|---|
| 571 | if it was followed or not) |
|---|
| 572 | - extended the ncache interface (lookup/insert/remove) to have the |
|---|
| 573 | ability to have multiple entries with the same name with different |
|---|
| 574 | handles based on some other tag (e.g. resolving a symlink object, |
|---|
| 575 | rather than what it points to). this is also not in use at the |
|---|
| 576 | moment. for now, no symlink objects will be inserted into the |
|---|
| 577 | ncache. |
|---|
| 578 | - added more ncache debugging |
|---|
| 579 | - added a fastpath return from client sysint lookup method on ncache |
|---|
| 580 | hit |
|---|
| 581 | - updated and extended all ncache test programs to work with the |
|---|
| 582 | changed API and fixed broken tests/verified that they still work |
|---|
| 583 | - kernel related: |
|---|
| 584 | - fixed all warnings generated from compiling the pvfs2 kernel |
|---|
| 585 | module under 2.6.9 kernels |
|---|
| 586 | - removed write_inode method, as it was unused and probably won't be |
|---|
| 587 | used |
|---|
| 588 | - removed unused -v command option to pvfs2-ls |
|---|
| 589 | - added command option -V (and --verbose) which can detect version |
|---|
| 590 | differences in the directory being read and will report them if |
|---|
| 591 | this switch is enabled |
|---|
| 592 | - fixed misc compilation warnings on Opteron/AMD64 machines |
|---|
| 593 | - added directory version to readdir downcall (passed from |
|---|
| 594 | pvfs2-client-core) |
|---|
| 595 | - removed include of modversions.h directly from pvfs2-kernel.h |
|---|
| 596 | |
|---|
| 597 | |
|---|
| 598 | pvfs2-0.7.0 |
|---|
| 599 | =========== |
|---|
| 600 | - fsck: server handles bogus datafiles better |
|---|
| 601 | - fsck: pvfs2-fsck is a little smarter about what it tries to salvage |
|---|
| 602 | - ib: avoid unsignaled WQE pileup |
|---|
| 603 | - ib: avoid polling cancelled connections (first stab toward true |
|---|
| 604 | cancel) |
|---|
| 605 | - ib: spin-block in test functions for better performance |
|---|
| 606 | - ib: do not "open" HCA, just grab a handle |
|---|
| 607 | - ib: fix leaking connection structs (thanks to D. Beilloin) |
|---|
| 608 | - ib: use faster 1k mtu |
|---|
| 609 | - ib: cleanup warning texts |
|---|
| 610 | - configure: add option to disable AIO threaded callbacks |
|---|
| 611 | - configure: fix GM and IB to enable only when explicitly requested |
|---|
| 612 | - add timestamps to gossip debugging to file and stderr (not syslog) |
|---|
| 613 | - ib: initial cancel support, works for pvfs2-ls |
|---|
| 614 | - add multihome support: servers can listen on multiple addresses (and |
|---|
| 615 | BMI types), clients choose the first address from tabfile that works |
|---|
| 616 | - bmi: poll adaptively based on recent usage |
|---|
| 617 | - added trove-dbpf support for internally limiting the number of |
|---|
| 618 | simultaneous aio operations allowed in progress; default value is 16 |
|---|
| 619 | - increased mmap-ra-small buf size from 4K to 16K to avoid many small |
|---|
| 620 | allocations (causes slightly larger mem footprint of client-core) |
|---|
| 621 | - adjusted client sysint setattr operation to work in a write-through |
|---|
| 622 | manner with the acache (when enabled) |
|---|
| 623 | - fixed client sysint setattr to invalidate the acache entry (if any) |
|---|
| 624 | - changed acache lookup to return the status (to avoid another acache |
|---|
| 625 | call that will always follow a successful lookup) |
|---|
| 626 | - internal acache improvements, such as removal of duplicated code |
|---|
| 627 | - updated acache-torture test program to match slightly new acache |
|---|
| 628 | interface |
|---|
| 629 | - make sure mmap's requesting MAP_SHARED fail (mmap2 returns -EINVAL, |
|---|
| 630 | userspace mmap returns standard MMAP_FAILED value) |
|---|
| 631 | - added compile time support for measuring roughly how long it takes |
|---|
| 632 | to process particular operations issued from the vfs |
|---|
| 633 | - modified PINT_sys_testsome to return immediately without calling |
|---|
| 634 | testcontext if any ops are completed and ready to be returned right |
|---|
| 635 | away |
|---|
| 636 | - made statfs return load information from servers |
|---|
| 637 | - gm: fixed performance bug, make sure test calls check completion |
|---|
| 638 | queue before sleeping |
|---|
| 639 | - gm: implement cancel functionality and verified for common cases |
|---|
| 640 | - fixed dbpf SYNC macro bugs that caused hangs on systems without aio |
|---|
| 641 | callback support |
|---|
| 642 | - updated pvfs2-config tool to use LIBS variable from configure |
|---|
| 643 | - removed -ldb from client side link stage |
|---|
| 644 | - added --serverlibs option to pvfs2-config to determine what |
|---|
| 645 | libraries have been linked against pvfs2-server |
|---|
| 646 | - updated makefile system for tests directory to use pvfs2-config and |
|---|
| 647 | deprecate use of .libs file |
|---|
| 648 | - added make install target for test harness programs |
|---|
| 649 | - introduced mutex locking in trove-handle-mgmt to avoid race |
|---|
| 650 | conditions that appear when statfs is called while trove operations |
|---|
| 651 | are in progress |
|---|
| 652 | - added utility functions for measuring elapsed wall, system, and user |
|---|
| 653 | time between specified points in code |
|---|
| 654 | - fix glaring alignment failure in PVFS_server_req |
|---|
| 655 | - fixed type of readahead_size in upcall for mmap-ra-cache that caused |
|---|
| 656 | the mmap-ra-cache to not work properly on PowerPC |
|---|
| 657 | - no longer look in the mmap-ra-cache for data on reads unless we're |
|---|
| 658 | sure we're doing an mmap or execution (as opposed to always) |
|---|
| 659 | - removed kernel module pvfs2_link call, as it was never used |
|---|
| 660 | - moved static copy_mntent method to PVFS_util_copy_mntent method |
|---|
| 661 | - added error handling to PVFS_util_copy_mntent |
|---|
| 662 | - renamed PVFS_sys_free_mntent to PVFS_util_free_mntent |
|---|
| 663 | - fixed successful return value of PVFS_util_copy_sys_attr |
|---|
| 664 | - fixed initialize-dyn test program that broken due to mntent changes |
|---|
| 665 | - changed get_data_sync_mode to explicitly return TROVE_SYNC if called |
|---|
| 666 | on an unregistered fs_id |
|---|
| 667 | |
|---|
| 668 | |
|---|
| 669 | pvfs2-0.6.5 |
|---|
| 670 | =========== |
|---|
| 671 | - broke several server state machines into multiple nested machines |
|---|
| 672 | - some PAV cleanups, including support for a larger number of meta |
|---|
| 673 | servers than io servers |
|---|
| 674 | - update k_size (number of keyvals) in dspace attr cache when the |
|---|
| 675 | number of keyvals on disk changes |
|---|
| 676 | - replaced all vfs 64 bit operation tags to be unsigned |
|---|
| 677 | - replaced pint-dev code to work with 64 bit unsigned tags |
|---|
| 678 | - moved all op initialization out of the constructor and into the |
|---|
| 679 | op_alloc routine |
|---|
| 680 | - fixed tag cancellation upcall/method to use a 64 bit tag, rather |
|---|
| 681 | than an unsigned long |
|---|
| 682 | - added a PVFS_util method to get the current system and return it as |
|---|
| 683 | a valid PVFS_time type |
|---|
| 684 | - added arguments to the crdirent/chdirent/rmdirent operations that |
|---|
| 685 | now can take optional parent atime/mtime/ctime fields |
|---|
| 686 | - added support on server *dirent operations that update the parent |
|---|
| 687 | time attributes (if specified) on successful completion of the |
|---|
| 688 | *dirent operation; null/zero time fields are not modified |
|---|
| 689 | - modified sys-create/sys-mkdir/sys-symlink/sys-rename/sys-remove to |
|---|
| 690 | work with the new operations properly; in general, |
|---|
| 691 | create/remove/rename operations updates the mtime and ctime of the |
|---|
| 692 | parent directory, which is now properly supported |
|---|
| 693 | - moved some common server side attribute handling code into a macro |
|---|
| 694 | to make it re-useable across several server state machines |
|---|
| 695 | - updated en{de}coding of modified operations |
|---|
| 696 | - remove sync calls on readonly trove operations |
|---|
| 697 | - added sanity check to kernel's device poll; makes sure the device is |
|---|
| 698 | opened by only one user before returning valid results |
|---|
| 699 | - make the device's request list waitqueue non-exclusive, since poll |
|---|
| 700 | waits as well |
|---|
| 701 | - some formatting changes on kernel error reporting |
|---|
| 702 | - added mmap-ra-cache support for partial cache fills on incomplete |
|---|
| 703 | requests; misc mmap-ra-cache enhancements |
|---|
| 704 | - cast setparam values to uint64_t rather than int64_t in admin utils |
|---|
| 705 | - remove trove sync call on server side root handle check |
|---|
| 706 | - modify server side remove state machine to check the k_size of the |
|---|
| 707 | dirdata object being removed if it's a directory to report early |
|---|
| 708 | back to the client that the directory is not empty (if it's not) |
|---|
| 709 | - remove the readdir checks in the client remove path now that the |
|---|
| 710 | server-side remove can tell us directly if a directory is not empty |
|---|
| 711 | - modified PVFS specific error routines to print the value of |
|---|

|---|
| 714 | - fixed 64bit compile warnings (AMD64/Opteron) |
|---|
| 715 | - split msgpair debugging into it's own class (no longer part of |
|---|
| 716 | 'client') |
|---|
| 717 | - break out clientcore debugging into its own debugging mask |
|---|
| 718 | - fixed trove error codes |
|---|
| 719 | - give trove flush and resize operations the ability to create the |
|---|
| 720 | bstream they're working with if it doesn't exist instead of |
|---|
| 721 | returning an error |
|---|
| 722 | - fixed bug in (threaded) trove that did not properly reinitialize |
|---|
| 723 | condition variables after the first finalize |
|---|
| 724 | - improvements to the storage space and collection removal code |
|---|
| 725 | - extensive trove cleanups and cruft removal |
|---|
| 726 | - check for error codes when doing server side getattr and reading |
|---|

|---|
| 728 | - invalidate attr cache on write_at calls (never used) |
|---|
| 729 | - changed pvfs2-showcoll coll_id prints from hex to decimal |
|---|
| 730 | - kernel changes: |
|---|
| 731 | - enable kernel readahead hints on mmap/execution (i.e. sequential) |
|---|
| 732 | - initialize kernel module's request_list_waitq at declaration time |
|---|
| 733 | - put large print statement into a macro for convenience |
|---|
| 734 | - make all bufmap allocations GFP_KERNEL, regardless of highmem usage |
|---|
| 735 | - use add_waitqueue_exclusive for the io_completion_waitq entries |

|---|
| 737 | |
|---|
| 738 | |
|---|
| 739 | pvfs2-0.6.4 |
|---|
| 740 | =========== |
|---|
| 741 | - added a pvfs2-config tool to help when compiling against pvfs2 |
|---|
| 742 | - new PAV option (COMPUTENODES_LAST) that controls whether compute |
|---|
| 743 | nodes are chosen first or last out of the total set of nodes |
|---|
| 744 | available |
|---|
| 745 | - fix locking bug introduced in 0.6.3 that shows up when trove is used |
|---|
| 746 | without aio callbacks |
|---|
| 747 | - explicitly name invalid msg tag value (0) |
|---|
| 748 | - modified pvfs2-ls to show the mtime (rather than atime) in long |
|---|
| 749 | listings |
|---|
| 750 | - updated set-info test program to update mtime (rather than atime) |
|---|
| 751 | - fixed possible flow mutex memory leak |
|---|
| 752 | - changed PVFS_time from an int64_t to a uint64_t |
|---|
| 753 | - fixed a pvfs2-fsck compile time warning |
|---|
| 754 | - fixed bug in sys-remove that erroneously tried to back out of the |
|---|
| 755 | remove even on error codes that are acceptable to return |
|---|
| 756 | - moved to fully 64 bit unsigned gossip masks (for some more possible |
|---|
| 757 | debugging levels) |
|---|
| 758 | - fixed bug in shared-state-machine getattr method that could allow |
|---|
| 759 | attributes to come out of the acache with incorrect types/fields |
|---|
| 760 | - fixed bug in crdirent msgpair setups for create/mkdir/symlink (used |
|---|
| 761 | incorrect handles in mappings) |
|---|
| 762 | - modified mgmt setparam call to take uint64_t parameters instead of |
|---|
| 763 | int64_t |
|---|
| 764 | - kernel changes: |
|---|
| 765 | - fixed bug that allowed a file removed on one client to still |
|---|
| 766 | appear on another with bad attributes |
|---|
| 767 | - fixed dentry revalidation to never return that a dentry is valid |
|---|
| 768 | if's negative |
|---|
| 769 | - fixed directory inode's mtime and ctime changes on updates |
|---|
| 770 | - fixed directory link counts for some changes |
|---|
| 771 | - simplify atime/mtime/ctime conversion to sys_attr (and vice versa) |
|---|
| 772 | to and from inode's time fields |
|---|
| 773 | |
|---|
| 774 | |
|---|
| 775 | pvfs2-0.6.3 |
|---|
| 776 | =========== |
|---|
| 777 | - added ability to negate log categories in |
|---|
| 778 | PVFS_debug_eventlog_to_mask |
|---|
| 779 | - added pvfs2-fsck |
|---|
| 780 | - updated pvfs2-quickstart to better discuss client configuration |
|---|

|---|
| 782 | with configure option --enable-epoll on linux 2.6 systems) |
|---|
| 783 | - fixed configure bug that dropped default CFLAGS in some cases |
|---|
| 784 | - adjusted trove id generation to make it easier to log trove events |
|---|
| 785 | - fixed Makefile.in bug that caused pvfs2-server.c dependency |
|---|
| 786 | information to be lost |
|---|
| 787 | - rewrote both threaded and nonthreaded versions of all job_testXXX() |
|---|
| 788 | functions |
|---|
| 789 | - fixed condition variable usage to avoid signaling races that could |
|---|
| 790 | lead to unecessary wait times |
|---|
| 791 | - simplified code path |
|---|
| 792 | - removed superfluous calls to gettimeofday() |
|---|
| 793 | - adjustment of condition variable usage in trove-dbpf to avoid races |
|---|
| 794 | similar to those found in job_testXXX() |
|---|
| 795 | - applied vim formatting patch to use spaces instead of tabs |
|---|
| 796 | - fixed pvfs2-server permission check to allow users of the same group |
|---|
| 797 | to have access to other group members attributes (for listing) |
|---|
| 798 | - fixed incorrect/invalid error codes and error handling |
|---|
| 799 | - fixed pvfs2-server crash bug due to io state machine potentially |
|---|
| 800 | freeing a reqsched id that was never posted |
|---|
| 801 | - added mgmt methods PVFS_{i}mgmt_get_dirdata_handle for retrieving |
|---|
| 802 | the internal dirdata handle of a specified 'parent' object (if any) |
|---|
| 803 | - fixed pvfs2-server crash bug (race) in trove that could return an |
|---|
| 804 | object on queue addition that has already been serviced |
|---|
| 805 | - extended server side mkdir state machine to create the internal |
|---|
| 806 | dirdata dspace when creating the directory (rather than waiting for |
|---|
| 807 | crdirent to create it if it doesn't already exist) |
|---|
| 808 | - added mgmt methods PVFS_{i}mgmt_create_dirent mgmt for creating |
|---|
| 809 | directory entries at a low level |
|---|
| 810 | - fixed request scheduler's acceptance of the mgmt-remove-* operations |
|---|
| 811 | while in admin mode (since these can be used in admin mode) |
|---|
| 812 | - extended mkspace (and thus pvfs2-mkspace program) to initalize a |
|---|
| 813 | lost+found directory after the root directory is made |
|---|
| 814 | - kernel changes: |
|---|
| 815 | - fixed credential usage bug that resulted in (seemingly random) |
|---|
| 816 | permission problems when using the file system as multiple users |
|---|
| 817 | - fixed a bug that appeared as data corruption due to mapped memory |
|---|
| 818 | pages in use being swapped out under heavy memory load under 2.4.x |
|---|
| 819 | kernels (and containing incorrect data on future accesses) |
|---|
| 820 | - remove slab poison flag from debug allocators, as some kernels |
|---|
| 821 | complain about how it was used |
|---|
| 822 | - do not use kmap/kunmap calls if not configured for HIGHMEM, as |
|---|
| 823 | some configurations cannot resolve these symbols |
|---|
| 824 | |
|---|
| 825 | |
|---|
| 826 | pvfs2-0.6.2 |
|---|
| 827 | =========== |
|---|
| 828 | - updated documentation for dist-simple-stripe.c and modified |
|---|
| 829 | the basic distribution to use a single data file object. |
|---|
| 830 | - fixed error reporting in pvfs2-server that didn't understand pvfs2 |
|---|
| 831 | specific error codes |
|---|
| 832 | - extended request scheduler to allow operations to pass through |
|---|
| 833 | without being scheduled (and allow the noop operations to work like |
|---|
| 834 | this) |
|---|
| 835 | - disabled the (unused) device interface on server builds, reducing |
|---|
| 836 | server run-time threads by one |
|---|
| 837 | - bmi optimizations: avoid polling in test calls if operations are |
|---|
| 838 | complete, or no operations are complete but there are unexpected |
|---|
| 839 | operations ready to be serviced |
|---|
| 840 | - extended the pvfs2-mkspace tool to be able to work with data and |
|---|
| 841 | meta handle ranges separately (also extended the internal interfaces |
|---|
| 842 | as necessary for this functionality) |
|---|
| 843 | - fixed bug in mkspace that could create the root directory dirent |
|---|
| 844 | object in a non-meta handle range |
|---|
| 845 | - added client side attribute type checking that avoids contacting |
|---|
| 846 | servers if we've determined that the operation we're about to |
|---|
| 847 | perform cannot be performed on an object of the type we were told to |
|---|
| 848 | work on. e.g., a readdir operation will not be issued to the server |
|---|
| 849 | if the getattr reports that the object we want to readdir on is not |
|---|
| 850 | a directory. most sysint operations now have this checking in place |
|---|
| 851 | - fixed crash bug on the server crdirent operation if passed a |
|---|
| 852 | non-directory object type |
|---|
| 853 | - fixed race condition triggered when pvfs2-server is getting many |
|---|
| 854 | more incoming operations than it has posted unexpected msgs for |
|---|
| 855 | - increase the default number of posted unexpected msgs by the server |
|---|
| 856 | - properly re-integrate and simplify the usage of the mmap-ra-cache, |
|---|
| 857 | which wasn't working properly after the pvfs2-client-core re-write |
|---|
| 858 | - fixed crash bug on the server due to an unexpected error code coming |
|---|
| 859 | out of pthread_cond_timedwait inside of job test calls |
|---|
| 860 | - modify configure script to append date and time information to non |
|---|
| 861 | release builds (for more fine grained version information if needed) |
|---|
| 862 | - fixed acache usage in sysint create/mkdir/symlink operations |
|---|
| 863 | - open-cache remove now syncs (if necessary) after the remove, rather |
|---|
| 864 | than just before |
|---|
| 865 | - removed duplicate 'open_cache' debugging keyword definition |
|---|
| 866 | - allowed client side logging (via PVFS2_DEBUGMASK/PVFS2_DEBUGFILE env |
|---|
| 867 | variables) to append to the specified logfile, rather than |
|---|
| 868 | truncating it if it already exists |
|---|
| 869 | - fixed bug in device test method that didn't properly adjust the |
|---|
| 870 | outcount on failure; also added the number of bytes read on a failed |
|---|
| 871 | (short) read |
|---|
| 872 | - started adding debugging code for printing out server side response |
|---|
| 873 | structures (only getattr is currently implemented) |
|---|
| 874 | - kernel changes: added some debugging and simplified the |
|---|
| 875 | handle_io_error macro. also added translation of non-errno pvfs2 |
|---|
| 876 | error codes (should it get one) to avoid returning entirely |
|---|
| 877 | incorrect error codes in some cases; avoid allowing -PVFS_ECANCEL to |
|---|
| 878 | be passed down to the kernel code from the pvfs2-client-core. use |
|---|
| 879 | i_size_read to update file position on opens for append. remove old |
|---|
| 880 | code that manually updated the inode's file size on writes |
|---|
| 881 | - replaced debugging mask of cancelled i/o operations from io to |
|---|
| 882 | cancel |
|---|
| 883 | - simplified pvfs2-statfs by retrieving all server statistics in one |
|---|
| 884 | call, rather than separate ones for meta and data servers; also |
|---|
| 885 | fixed reporting of server duties (previously all servers were |
|---|
| 886 | reported as serving both meta and i/o data) |
|---|
| 887 | - added a start banner to pvfs2-client-core if client debugging is |
|---|
| 888 | enabled. this allows easier visual inspection of restarts in logs |
|---|
| 889 | - fixed bug when copying credentials to first make sure that they're |
|---|
| 890 | valid in all sysint/mgmt calls |
|---|
| 891 | - added both server and client side (mgmt) operations to remove |
|---|
| 892 | arbitrary pvfs2 objects and directory entries without prejudice |
|---|
| 893 | - added a 'pvfs2-remove-object' tool that can remove pvfs2 objects and |
|---|
| 894 | directory entries (use is not generally encouraged) |
|---|
| 895 | - fixed pvfs2-fs-dump crash bugs when it fails to find some objects it |
|---|
| 896 | was expecting to see |
|---|
| 897 | - adjusted the time that pav allows for copying binaries out to remote |
|---|
| 898 | machines |
|---|
| 899 | - fixed bug bmi_tcp potential send deadlock under heavy loads |
|---|
| 900 | - added a mgmt method that allows parameter sets on single servers |
|---|
| 901 | (rather than the previous one that allowed only all servers) |
|---|
| 902 | - extended pvfs2-set-debugmask program to have the ability to set the |
|---|
| 903 | debug mask on a single server (rather than all) via cmdline options |
|---|
| 904 | - replaced TroveSyncMode configuration option with separate |
|---|
| 905 | TroveSyncMeta and TroveSyncData options. the default values are yes |
|---|
| 906 | for both |
|---|
| 907 | - updated pvfs2-genconfig to reflect TroveSync* config option changes |
|---|
| 908 | - implemented understanding of the data sync mode option in the flow |
|---|
| 909 | interface via the setinfo method |
|---|
| 910 | - modified pvfs2-server to pass data sync mode option to the flow |
|---|
| 911 | implementation via setinfo on a per fs basis |
|---|
| 912 | |
|---|
| 913 | |
|---|
| 914 | pvfs2-0.6.1 |
|---|
| 915 | =========== |
|---|
| 916 | - misc. updates to msgpairarray and associated tools to allow for |
|---|
| 917 | server side use |
|---|
| 918 | - reorganization of server request parameters so that more (but not |
|---|
| 919 | all yet) are stored in a centralized table |
|---|
| 920 | - removed some deprecated test programs |
|---|
| 921 | - new pint-util.[ch] to contain utility functions shared between |
|---|
| 922 | client and server |
|---|
| 923 | - some refactoring of server state machines (mainly crdirent) to allow |
|---|
| 924 | for code reuse in other state machines |
|---|
| 925 | - no longer need to fix up generated html by hand |
|---|
| 926 | - fixed a bug that allowed an open through the vfs without the O_CREAT |
|---|
| 927 | and O_EXCL flags to return -EEXIST (should be success in that case) |
|---|
| 928 | - added a file_open.c test program that tests opens in various modes |
|---|
| 929 | - error code cleanups (added PVFS_EACCES mapping to EACCES; moved |
|---|
| 930 | PVFS_EDETAIL to be a non-errno error code) |
|---|
| 931 | - fixed pvfs2-ls to properly convert reported file times in user's |
|---|
| 932 | configured system localtime, rather than in UTC |
|---|
| 933 | - fixed the kernel module information so that modinfo doesn't report |
|---|
| 934 | many duplicate entries |
|---|
| 935 | - fixed server pidfile usage (-p cmdline option) |
|---|
| 936 | - fixed msgpair retries to properly delay between retry attempts |
|---|
| 937 | - added trove hooks to be able to peek at handles that will be |
|---|
| 938 | allocated later |
|---|
| 939 | - cleaned up the remove state machine and removed an unnecessary |
|---|
| 940 | allocation/copy |
|---|
| 941 | - fixed existing acache usage in the sysint calls to be more uniform; |
|---|
| 942 | removed some overhead in the sysint |
|---|
| 943 | - fixed kernel device close to be aware if mounts are still active |
|---|
| 944 | - added more tests to pvfs2-shell-test that test deeply nested |
|---|
| 945 | subdirectories |
|---|
| 946 | - added a method to determine the min handle recycle time across all |
|---|
| 947 | configured servers' file systems |
|---|
| 948 | - changed code formatting rules to use spaces rather than tabs in vim |
|---|
| 949 | - fixed bug that didn't reload the cached config information on file |
|---|
| 950 | system removal (i.e. unmounts) |
|---|
| 951 | - added a cmdline argument to pvfs2-client to specify the acache |
|---|
| 952 | timeout to use at run-time (default is 0 milliseconds, which is |
|---|
| 953 | effectively disabled). this timeout is upper bounded by the min |
|---|
| 954 | handle recycle time across all servers, and it can change |
|---|
| 955 | dynamically as new mounts come and go |
|---|
| 956 | - fixed a bug that allowed servers to create internal storage objects |
|---|
| 957 | outside of the meta handle ranges in some circumstances |
|---|
| 958 | - replace single element msgpair/array setup code where possible with |
|---|
| 959 | a macro |
|---|
| 960 | |
|---|
| 961 | |
|---|
| 962 | pvfs2-0.6.0 |
|---|
| 963 | =========== |
|---|
| 964 | - removed pvfs2-import and pvfs2-export in favor of pvfs2-cp |
|---|
| 965 | - added compile time option for disabling thread-safety in the client |
|---|
| 966 | library (enabled by default; --disable-thread-safety to disable) |
|---|
| 967 | - improved configure summary information emitted at configure time |
|---|
| 968 | - added missing non-blocking sysint declarations to sysint header |
|---|
| 969 | - made sysint test and testsome() calls more useable |
|---|
| 970 | - merged dev unexp polling/handling with system interface |
|---|
| 971 | - added PINT_sys_dev_unexp call that allows posting unexpected device |
|---|
| 972 | messages so that they can be returned from the sysint testsome |
|---|
| 973 | method in addition to completed sysint operations |
|---|
| 974 | - added a id_gen_fast_unregister macro that is a no op, to make the |
|---|
| 975 | api more consistent with the id_gen_safe_* calls |
|---|
| 976 | - modified device driver to work properly in non-blocking mode from |
|---|
| 977 | userspace by implementing the character device poll method and |
|---|
| 978 | modified the pint-dev device interface to make sure it can handle |
|---|
| 979 | the pvfs2 device in a non-blocking manner; added a no immediate |
|---|
| 980 | completion option to the device interface; made test more efficient |
|---|
| 981 | by not polling if no idle time is specified; check for poll errors; |
|---|
| 982 | use proper buffer sizes for reads across the device |
|---|
| 983 | - added a method to free the mapped memory region on pvfs2-client-core |
|---|
| 984 | shutdown (valgrind complained) |
|---|
| 985 | - modified all job uses of the id-generator to use the safe, rather |
|---|
| 986 | than fast, methods (useful for several reasons including safe |
|---|
| 987 | cancellation of already completed operations) |
|---|
| 988 | - modified the job_dev_unexp method to have (and honor) the no |
|---|
| 989 | immediate completion flag if passed (used in the pvfs2-client-core) |
|---|
| 990 | - re-wrote pvfs2-client-core to use sysint non-blocking operations |
|---|
| 991 | - improved human readable size reporting |
|---|
| 992 | - allow human readable size reporting to optionally use si units |
|---|
| 993 | - added --si option to pvfs2-ls (similar to ls's --si option) |
|---|
| 994 | - added -H option to pvfs2-statfs (similar to du's -H option) |
|---|
| 995 | - added a method able to cancel I/O operations in progress |
|---|
| 996 | - removed kernel ability to kill device file on cancelled I/O |
|---|
| 997 | - added the ability of sys-io.sm to handle run-time cancellation while |
|---|
| 998 | still transitioning properly |
|---|
| 999 | - added support in the pvfs2-client for ignoring an upcall retry for |
|---|
| 1000 | an op already in progress (as opposed to servicing it multiple |
|---|
| 1001 | times) |
|---|
| 1002 | - added kernel method that allows the cancellation upcall/downcall |
|---|
| 1003 | cycle to progress, ignoring the fact that a signal is pending (since |
|---|
| 1004 | the only time a cancellation is issued is when there's a signal |
|---|
| 1005 | pending) |
|---|
| 1006 | - fixed kernel oops on setattr (signal) interruption by returning a |
|---|
| 1007 | valid error code in this case |
|---|
| 1008 | - full acache cleanup, bugfixes, and thread-safety support |
|---|
| 1009 | - allow the sysint post() method to complete an op if finished |
|---|
| 1010 | (i.e. all states are immed. completion) by adding it to the |
|---|
| 1011 | completion list (which test/testsome can retrieve) |
|---|
| 1012 | - removed 'cached' attribute fields from getattr_sm object |
|---|
| 1013 | - removed mostly duplicated code from shared-state-methods.c |
|---|
| 1014 | - added support (testing only) for building a threaded client library |
|---|
| 1015 | - gracefully terminate thread-mgr testing threads on errors (this is |
|---|
| 1016 | only really useful for graceful shutdown of the threaded client |
|---|
| 1017 | library) |
|---|
| 1018 | - added a set_info option to bmi that tells it to be more aggressive |
|---|
| 1019 | when cancelling operations (bmi_tcp will now close sockets) |
|---|
| 1020 | - fixed kernel bugs that didn't release the bufmap indices in use on |
|---|
| 1021 | some error paths (eventually caused all of them to be permanently |
|---|
| 1022 | used which caused hangs on I/O) |
|---|
| 1023 | - extended msgpairarray code to only retry msgpairs that haven't |
|---|
| 1024 | completed already |
|---|
| 1025 | - increased kernel module single operation timeout to be 60 seconds |
|---|
| 1026 | instead of 30 seconds (note: as a side-effect this also extends the |
|---|
| 1027 | amount of time you'll have to wait on interrupted operations via |
|---|
| 1028 | signal for now) |
|---|
| 1029 | - added PVFS_strerror_r; an equivalent to strerror_r (the thread-safe |
|---|
| 1030 | strerror call) that handles PVFS_error codes |
|---|
| 1031 | - added a simple file_write test program (tests are not in releases) |
|---|
| 1032 | - always delay for 1 second before spawning the pvfs2-client-core from |
|---|
| 1033 | within the pvfs2-client to avoid filling dmesg with harmful looking |
|---|
| 1034 | errors while restarting (and re-opening the device file) |
|---|
| 1035 | - new trove component called dbpf-open-cache that caches open file |
|---|
| 1036 | descriptors and db references; replaces dbpf-bstream-fd-cache, |
|---|
| 1037 | dbpf-dspace-db-cache, and dbpf-keyval-db-cache; fixes a few long |
|---|
| 1038 | standing file size and attribute bugs |
|---|
| 1039 | - added a few missing admin tools to make install target |
|---|
| 1040 | - more attribute debugging messages or server |
|---|
| 1041 | - added admin utility program pvfs2-chown |
|---|
| 1042 | - added make lib/pvfs2-threaded.a target that can be used to build a |
|---|
| 1043 | multithreaded version of the pvfs2 client library |
|---|
| 1044 | - thread safety for dynamic activation of bmi methods |
|---|
| 1045 | - fixed makefile LD selection and html docs target |
|---|

|---|
| 1080 | report exec failures. we can't do that anymore with this setup, so |
|---|
| 1081 | we'll have to either require an absolute path to the client |
|---|

| 1102 | - translate error codes that occurred while waiting for the |
|---|
| 1103 | downcall, rather than assuming an error came back from the |
|---|

|---|
| 1105 | invalid mounts |
|---|
| 1106 | - use fully 64-bit op tags instead of relying on unreliable casts |
|---|
| 1107 | and assumptions moving from kernel space to userspace; changes use |

|---|
| 1109 | without problems now |
|---|
| 1110 | - changed pre-posted write_ack recv posting to have an infinite |

|---|
| 1114 | - fixed crash bugs when an invalid (or unsupported) encoding type is |

| 1115 | specified by reporting the error to the user, and the completing the |
|---|
| 1116 | operation if possible by cycling through the valid encoders |
