0.6.5

gufi_query

• Amortize external database views creation when -Q is not provided
• Amortize xattr views creation when -x is not passed in

gufi_rollup

  • Unified with gufi_unrollup SQL
• treesummary is no longer copied upwards when rolling up
• Index summary.inode to speed up queries
• Fixed accidental modification of index during dry run

QueuePerThreadPool

• Claimed work can now be stolen to prevent starvation caused by long running threads
• If there is work that can be stolen, at least one work item will be taken even if the multiplier results in 0

External Databases:

• Admins no longer have to know what files to track
• Changed external databases to be set by users in per-directory files called external.gufi that list one path per line
  • Relative paths with be treated as relative to the source tree (not the current directory in the index)
  • Changed -q to check that external db files listed are valid
• Now tracked in trace files (old trace files do not have to be changed)

contrib/gufi_sqlite -> src/gufi_sqlite3

• Added printing results - previous usage did not require it

NEW gufi_index2dir

• Convert an index into a source tree with file sizes of 0

NEW gufi_trace2dir

• Convert trace files into a source tree with file sizes of 0

NEW parallel_cpr

• Parallel cp -r

• gufi_dir2index/gufi_dir2trace -q
  • Added e type to trace file format - does not affect old trace files
• gufi_query -I -Q

    • Always available, but will not be filled unless -Q is used.
  • Reorganized processdir to be easier to read
• External user database count is tracked in treesummary
• Removed attachname column from external_dbs

Extended Attributes:

• xattrs view and convenience views are now always available, but only filled when -x is passed to gufi_query

parallel_rmr top-level directory bug fix

Longitudinal Snapshot:

• More columns
• Cache intermediate results
• Allow for rolled up indexes
• Different views
  • Graph (G)
  • Per Level (L)
  • Siblings (S)
  • Per Directory (D)

Dependencies:

• Updated sqlite3-pcre to use pcre2
  • Existing installs should delete the GUFI sqlite3-pcre build/install and rebuild
• Removed paramiko tarball
• Added new SQLite3 patch to increase attach limit to 254

0.6.3

gufi_query:

• Input paths can now be symlinks
• Immediate subdirectories of input paths can now be symlinks
• gufi_query will get the realpath of the top-level input paths for traversal, but the custom SQLite functions path and rpath will print the current path with the original user provided prefix
  • fpath still prints the actual path

Schema changes:

• Added ppinode to pentries
• dmaxgidI → dmaxgid
• inode INT64 → inode TEXT

New: contrib/longitudinal_snapshot.py

• Takes snapshot of an index tree and summaries each directory's metadata i.e. min, max, mean, median, histograms, etc. of file size, file count, timestamps, string lengths, etc., and places data into a single SQLite database file that is much smaller than the index itself
  • Recommend running gufi_treesummary_all before generating a snapshot
• See Discussion in #149

New: contrib/treediff

• Walks directory tree and prints top-most directory mismatches

More tests

• Added empty directory to test tree
• Added deploy test

GitHub Actions

0.6.2

Schema Changes:

• summary now has a 0 size count column called totzero
• New views summarylong and vrsummarylong join summary and vrsummary with tables/views that contain additional data that should be associated with them but do not need to be added into the summary table. Currently, no extra information is attached.

${SEARCH} now contains an empty db.db to guarantee a db.db above all indexes under ${SEARCH}.

• This can be expanded in the future to add information that is separate from the rest of the index tree.
• Fixes #49

NEW: gufi_treesummary_all generates treesummary tables for all directories in an index instead of one directory at a time.

gufi_rollup now also generates treesummary tables while processing index

• gufi_unrollup does not remove treesummary tables because there is no way to tell whether or not they were generated by gufi_rollup or not. Might add column to say what utility was used to generate them in the future.

gufi_stat → gufi_stat_bin

• gufi_stat is now a script that calls gufi_stat_bin
• Server configuration file now also needs the path to gufi_stat_bin

gufi_stats

• average-leaf-files
• average-leaf-links
• average-leaf-size
• median-leaf-links
• median-leaf-size
• filesize-log2-bins
• filesize-log1024-bins
• dirfilecount-log2-bins (#146)
• dirfilecount-log1024-bins (#146)

Scripts now have a --verbose/-V flag to print the command being run (#142)

bfwreaddirplus2db was reorganized.

NEW: split_trace splits trace files into chunks for parallel processing by gufi_trace2index

SQLite3

• Updated from version 3.27 to version 3.43 to get built-in math functions

  • Existing indexes should be rebuilt

• Also added math functions stdevs, stdevp, and median

• Replaced subdirs_walked() with subdirs(srollsubdirs, sroll)

When printing result columns, the delimiter after the last column is no longer printed

• Prevents pandas from unnecessarily generating a column of Nones when parsing output

Significant increase in testing and code coverage

CMake

• db2, fuse, and gpfs tool building can be disabled even if the libraries are found
• Added make pylint, make shellcheck, and make checkstyle
• gufi_client_jail should not have been created
• Example configuration files are no longer renamed to config.example

GitHub Actions:

• Now building on macOS 11, 12, and 13
• Now building with -Wall -Wextra -Werror -pedantic

Added cygwin GCC support (not tested with CI)

QueuePerThreadPool

• Added soft memory limit to via deferred processing
