2022-01-06 Sergey Poznyakoff <gray@gnu.org>
Speed up flushing the bucket cache on disk
The implementation of _gdbm_cache_flush becomes prohibitively
inefficient during extensive updates of large databases. The
bug was reported at https://github.com/Perl/perl5/issues/19306.
To fix it, make sure that all changed cache entries are placed
at the head of the cache_mru list, forming a contiguous
sequence. This way a potentially long iteration over all cache
entries can be cut off at the first entry with ca_changed ==
FALSE.
This commit also gets rid of several superfluous fields in
struct gdbm_file_info:
- cache_entry
Not needed, because the most recently used cache entry
(cache_mru) is always the current one.
- bucket_changed
dbf->cache_mru->ca_changed reflects the status of the
current
bucket.
- second_changed
Not needed because _gdbm_cache_flush, which flushes all
changed
buckets, is now invoked unconditionally by _gdbm_end_update
(and
also whenever dbf->cache_mru changes).
* src/gdbmdefs.h (struct gdbm_file_info): Remove cache_entry.
The current cache entry is cache_mru. Remove bucket_changed, and
second_changed. All uses changed.
* src/proto.h (_gdbm_current_bucket_changed): New inline
function.
* src/bucket.c (_gdbm_cache_flush): Assume all changed elements
form a contiguous sequence beginning with dbf->cache_mru.
(set_cache_entry): Remove. All callers changed.
(lru_link_elem,lru_unlink_elem): Update dbf->bucket as
necessary.
(cache_lookup): If the obtained bucket is not changed and is
going to become current, flush all changed cache elements.
* src/update.c (_gdbm_end_update): Call _gdbm_cache_flush
unconditionally.
* src/findkey.c: Use dbf->cache_mru instead of the removed
dbf->cache_entry.
* src/gdbmseq.c: Likewise.
* tools/gdbmshell.c (_gdbm_print_bucket_cache): Likewise.
* src/falloc.c: Use _gdbm_current_bucket_changed to mark the
current bucket as changed.

* src/gdbmdelete.c: Likewise. Use _gdbm_current_bucket_changed.

gdbmtool: bugfixes
2021-11-15 Sergey Poznyakoff <gray@gnu.org>
gdbmshell: fix exit on error and improve directory/bucket
inspection.
Output from the "dir" command includes, for each directory
entry, the corresponding hash prefix.
The "bucket" command, when used without arguments, assumes
current bucket. Its output includes: bucket local depth, number
of directory entries pointing to that bucket (references), and,
if the latter is greater than one, indexes to the first and last
directory entries where it is referenced.
New command "sibling" inspects the sibling bucket of the current
one, i.e. the bucket corresponding to the hash prefix with the
last bit inverted.

Change semantics of the errorexit variable.
The "errorexit" variable is a string variable with the same
syntax as errormask. If a GDBM error is reported and the
corresponding gdbm_errno value is listed in this variable,
further script execution is aborted.
Setting it as boolean value is equivalent to set
errorexit="all".
* src/gdbmshell.c (all handlers): Return a GDBMSHELL_* error
code.
(closedb): Unset the fd variable only after closing the
database.
(run_command): If handler reported GDBM error and gdbm_errno is
listed in the errorexit variable, return 1 (which will cause
YYABORT in parser).
* src/gdbmtool.h (VAR_ERR_GDBM): New variable error code.
(variable_has_errno): New function.
(gdbm_error_is_masked): Rewrite using variable_has_errno.
* src/gram.y: Abort if run_command or run_last_command return
!0. Handle VAR_ERR_GDBM.
* src/var.c (variable): New member: data.
(errorexit variable): Change type to VART_STRING; install
sethook and typeconv.
(variable_unset): When unsetting string variable, free and reset
its value.
(cachesize_sethook,centfree_sethook)
(coalesce_sethook): Return VAR_ERR_GDBM on gdbmshell_setopt
error.
(errormask_sethook): Keep the mask vector in the data member.
Handle conversions from boolean.
(errorexit_sethook): Call errormask_sethook unless in
interactive session.

New gdbmtool variables: errorexit and errormask.
Boolean errorexit controls whether script terminates upon first
erroneous return from run_command or its derivatives. The
variable can be set only in non-interactive mode.
errormask is a comma-delimited list of GDBM error codes that are
masked, i.e. that won't trigger a diagnostic message if they
occur.
* src/gdbmshell.c (all handlers): Return integer value
indicating success (0) or failure (!0).

The new bucket cache uses the least recently used replacement
policy (instead of the least recently read, implemented
previously). It also allows for quick bucket lookups by the
corresponding disk address. To this effect the cache entries
form a red-black tree sorted by bucket address.
Additionally, data buckets are also cached.

database as a READER and "-n" for opening the database as
a NEWDB writer. The default mode remains the WRCREAT mode.

variables from int to long. This should not make any difference
to systems where sizeof(int) = sizeof(long). It should make
it easier to move to other systems.

NULLs being used as error indications, data cannot be NULL also.
* gdbmfetch.c, gdbmseq.c, fetch.c: Added checks for zero sized
key and content so malloc will not try to allocate zero bytes.
* gdbmconst.h: Added this file so that all constants are in one
central place. A few constants can be changed without changing
the header sizes.
