-2005-04-18  Michael Tokarev  <mjt@corpit.ru>
-
-	* move cdb_make_find.c content into cdb_make_put.c
-
-	* introduce CDB_PUT_REPLACE0 - zerofill old duplicates
-
-	* allow usage of cdb.h in C++
-
-2005-04-11  Michael Tokarev  <mjt@corpit.ru>
-
-	* do not autogenerate files (cdb.h.in, cdb.3.in etc), but
-	  use real files instead (only substituted VERSION and NAME)
-
-	* finally fixed the `!fputs()' condition to be `fputs() < 0'
-	  as it should be in cdb.c (misbehaves on *bsd)
-
-	* kill cdbi_t usage in cdb_int.h
-
-	* export _cdb_make_fullwrite() (was ewrite()) and _cdb_make_flush()
-	  and use them in cdb_make.c as appropriate
-
-	* almost completely rewrite _cdb_make_find() and friends:
-	  - _cdb_make_find() now accepts new parameter, remove (bool), which,
-	    if true, indicates all found records should be deleted from the
-	    database.
-	  - Call _cdb_make_find() with remove=0 from cdb_make_exists()
-	  - Call _cdb_make_find() with appropriate arguments from
-	    cdb_make_put(), and simplify the latter greatly (was too clumsy
-	    anyway)
-
-	* rename `flags' parameter in cdb_make_put() to be `mode' which is
-	  more appropriate
-
-	* change #if conditional in nss_cdb.c
-	  from __GLIBC__ to __GNU_LIBRARY__
-
-2003-11-04  Michael Tokarev  <mjt@corpit.ru>
-
-	* added cdb_get() routine: tinycdb officially uses mmap.
-
-	* added cdb_{get,read}{data,key}() macros to read and get
-	  current data and key.
-
-	* fixed bug in cdb_seek() - incorrect wrap, sometimes
-	  cdb_seek()+cdb_bread() may return EIO instead of finding
-	  correct record.
-	
-	* added some tweaks to Makefile to build position-independent
-	  libcdb_pic.a and shared libcdb.so libraries.  Note that
-	  using libcdb as shared library is probably not a good idea,
-	  due to tiny size of the library.
-
-	* added initial nss_cdb module.  Still not well-tested.
-	  Probably will not build on non-GNU system.
-
-	* adjusted tests.{ok,sh} for latest cdb utility modifications
-	  (-a mode in query by default)
-
-	* Victor Porton (porton at ex-code.com) provided a patch
-	  to allow tinycdb to be built on win32 platform (cdb_init.c).
-	  Completely untested.
-
-2003-08-13  Michael Tokarev  <mjt@corpit.ru>
-
-	* s/cdbi_t/unsigned/g.  No need to keep this type.
-
-	* changed usage of cdb_findnext(): one need to pass
-	  pointer to cdb structure to cdb_findnext() now,
-	  and should use cdb_datapos(struct cdb_find *)
-	  instead of cdb_datapos(struct cdb *)
-
-	* added cdb_seqinit() and cdb_seqnext() routines for sequential
-	  record enumeration
-
-	* addded cdb_dend to the cdb structure: end of data
-	  position.  Use that in cdb_seq*().
-
-	* more strict checking: ensure data is within data section,
-	  and hash tables are within hash section of a file.
-
-	* cdb_make.c (cdb_make_start): zerofill cdb_make structure
-	  to shut valgrind up (writing uninitialized data to file)
-	
-	* cdb.c (cmode): always open file in RDWR mode to allow
-	  duplicate key detection
-

-
-2001-12-10  Michael Tokarev <mjt+cdb@corpit.ru>

-
-2001-10-14  Michael Tokarev <mjt+cdb@corpit.ru>
-
-	* version 0.7

-
-2001-07-26  Michael Tokarev <mjt+cdb@corpit.ru>
-
-	* version 0.6
-
-	* added another option, CDB_PUT_WARN, to cdb_make_put's flags
-	  (to allow adding unconditionally but still warn about dups),
-	  now cdb_make_put seems to be logically complete.
-
-	* added and documented -r and -u options for cdb(1) command,
-	  and made them consistent with -w and -e also.
-
-	* reorganized cdb(1) manpage and added changes made to cdb
-	  command.
-
-	* added version references to manpages (and make them autogenerated
-	  to simplify maintenance).
-
-	* added cdb(5) manpage describing CDB file format.
-
-2001-07-25  Michael Tokarev <mjt+cdb@corpit.ru>

-Summary: TinyCDB - a Constant DataBase
-
-%description
-tinycdb is a small, fast and reliable utility set and subroutine
-library for creating and reading constant databases. The database
-structure is tuned for fast reading:
-+ Successful lookups take normally just two disk accesses.
-+ Unsuccessful lookups take only one disk access.
-+ Small disk space and memory size requirements; a database
-  uses 2048 bytes for the header and 24 bytes plus size of
-  (key,value) per record.
-+ Maximum database size is 4GB; individual record size is not
-  otherwise limited.
-+ Portable file format.
-+ Fast creation of new databases.
-+ No locking, updates are atomical.
-
-This package contains both the utility and the development
-files, together with nss_cdb module.

+tinycdb-0.80 2023-09-17
+
+ - bugfix: cdb utility: check return value from close() too,
+   when creating the cdb file
+
+ - portability: cdb utility: ignore SIGXFSZ signal if defined,
+   to be able to clean up when exceeding file limit
+
+ - robustness: let cdb_make_start to lseek() to the zero position
+   of file. This ensures the file is seekable right at the start
+   instead of at the very end, too
+
+ - robustness: cdb utility: remove temporary file in case create
+   operation fails
+
+ - portability use SEE_SET macro instead of 0 for lseek()
+
+ - split out cdb_pack() into its own .c file
+
+tinycdb-0.79 2023-09-17
+
+ - bugfix: call fsync() at the end of cdb_make_finish()
+   to ensure data does not stay in some kernel buffer
+
+ - bugfix: clean tests.out in `make distclean' too
+
+ - `make dist' makes tarball in the parent dir
+
+ - stop shipping debian/* - it is not a native debian package
