We'll assume these are supposed to be nominal variables. + +2007-03-30 Ben Pfaff + + * procedure.c: Adapt to new deque data structure. + +Mon Feb 19 10:53:21 2007 John McCabe-Dansted + Ben Pfaff + + * file-name.c: Mingw compatibility fixes. + (fn_search_path): Use ISSLASH instead of comparing against '/' + directly. + (fn_dir_name): Use dir_name from gnulib. + (fn_is_absolute): Use IS_ABSOLUTE_FILE_NAME from gnulib. + (fn_get_identity): Use GetFullPathName instead of canonicalize + from gnulib, because the latter does not fully support + Windows-style path names. Use this implementation based on the + detected presence of Windows instead of the absence of Unix, since + the new implementation is Windows-specific. + (fn_compare_file_identities): In Windows implementation, compare + names case-insensitively. + +Sun Feb 18 13:28:02 2007 Ben Pfaff + + * make-file.c: Don't include mkstemp.h, because gnulib now causes + to have the same effect. + +Sun Feb 18 11:20:24 2007 Ben Pfaff + + * por-file-reader.c: Add missing _() around messages. + +Sun Feb 11 20:44:13 2007 Ben Pfaff + + * make-file.c: Include "mkstemp.h", without which linking on + mingw32 fails. + +Thu Feb 8 14:59:05 2007 Ben Pfaff + + Reduce platform dependence. + + * file-name.c (fn_tilde_expand): Removed, and removed calls to it. + Everywhere we using this, we really should have just depended on + the shell to expand tildes. + (fn_search_path): Simplify, given that we don't do tilde expansion + any longer. + (fn_normalize): Removed. Caller changed to use the canonicalize + module from gnulib. + (fn_get_cwd): Removed. Only user was fn_normalize. + (fn_is_absolute): Really only test for absolute names. + (fn_is_special): Use pipe files if HAVE_POPEN, not if we're in + unix. + (fn_readlink): Removed, as it was only used fn_normalize. + (fn_exists): Assume the stat function is available; gnulib does. + (fn_open): Use pipe files if HAVE_POPEN, not if we're in unix. + +Sat Feb 3 21:52:17 2007 Ben Pfaff + + * dictionary.c (dict_create_vector_assert): New function. + +Wed Feb 7 21:25:15 2007 Ben Pfaff + + * file-name.c (fn_normalize): Correct name of function + fn_is_special. Thanks to John McCabe-Dansted + for pointing this out. + +Thu Feb 1 16:53:37 2007 Ben Pfaff + + We are using a single member in struct file_handle, the "name" + field, for more than one purpose. When it begins with '"', it's a + file name; otherwise, it's a token that can be used to identify + it. When that assertion fires, it's because we searched for the + name case-sensitively as a file name (so that there was no match), + and then we try to insert it case-insensitively as a token, which + fails because duplicates aren't allowed. + + Solution: break the two purposes into two separate fields. This + fixes the problem and likely makes the code easier to read too. + + Fixes bug #18922. Thanks to John Darrington for bug report and + review. + + * file-handle-def.c (struct file_handle): New `id' member. + (fh_from_name): Rename fh_from_id. Update all callers. + (create_handle): New `id' parameter. Update all callers. + (fh_create_file): Ditto. + (fh_get_id): New function. + +Mon Jan 15 16:18:10 2007 Ben Pfaff + + * case.c (case_is_null): Change return type to bool. + +Mon Jan 15 10:57:28 2007 Ben Pfaff + + Add debugging code. + + * case.c (case_clone) [DEBUGGING]: When debugging, don't use + reference counting to share data. This makes it easy for + valgrind, etc. to find accesses to cases that have been destroyed + but have been kept around by another user's ref-count. This often + happens when the data set is small enough to find in memory; if a + bigger data set that would overflow to disk were used, then data + corruption would occur. + +Mon Jan 15 10:55:18 2007 Ben Pfaff + + Simplify code. + + * case.c (case_unshare): Make it check internally whether the + ref_cnt is greater than 1, so that the callers don't have to. + Update callers not to check. + +Mon Jan 15 10:53:01 2007 Ben Pfaff + + Before, I was thinking that I might want to get rid of reference + counting at some point. Now, I'm pretty sure that it's here to + stay. Thus, because we have to store the value_cnt anyway for + reference-counted cases, we might as well expose it to users. + + * case.c (case_get_value_cnt): New function. + (case_resize): Drop OLD_CNT argument. Update all callers. Only + resize case if its size actually changed. + + * casefile.c (casefile_append_xfer): Use case_get_value_cnt + instead of peeking inside struct case directly. + (casefile_append): Ditto. + +Mon Jan 15 10:50:22 2007 Ben Pfaff + + Get rid of the inlines for the case functions, which made the + header file hard to read. (Also, in testing with "-O2 -DNDEBUG", + the inlines didn't speed up "make check" at all, which is not a + perfect benchmark but seems indicative.) + + * case.c: Remove #ifdef DEBUGGING...#endif around many function + definitions. Remove some assertions on nonnull pointers that were + redundant with a pointer dereference soon after in the function. + Also: + (struct case_data): Move definition here from case.h. + (case_data): Ditto. + (case_num): Ditto. + (case_str): Ditto. + (case_data_wr): Ditto. + +Sun Jan 14 21:41:12 2007 Ben Pfaff + + * automake.mk: Add casedeque.h to sources. + + * casedeque.h: New file. + + * procedure.c: (struct dataset) Change lag_count, lag_head, + lag_queue member into single struct casedeque member. Update all + users to use the casedeque instead. + (lag_case) Removed. + +Sun Jan 14 21:43:12 2007 Ben Pfaff + + * procedure.c: Simplify lagged cases interface. Updated all + clients--well, the only client--to use the simplified interface. + (dataset_n_lag) Removed. + (dataset_set_n_lag) Removed. + (dataset_need_lag) New function. + +Tue Jan 9 07:20:05 WST 2007 John Darrington + + * dictionary.c procedure.c: More changes to ensure that callbacks occur + whenever appropriate, but only when the dataset/dictionary is in a + consistent state. + +Sun Jan 7 08:33:04 WST 2007 John Darrington + + * dictionary.c dictionary.h : Added callbacks for change of filter and + split variables. Refactored some code to ensure that callbacks get + invoked when appropriate. + + * procedure.c (proc_cancel_temporary_transformations): Make sure that + replace_dict callback occurs when permanent_dict replaces the current + dictionary. + +Wed Jan 3 11:02:11 WST 2007 John Darrington + + * dictionary.c dictionary.h : Added callback for when the weight + variable of a dictionary changes. + +Mon Jan 1 10:36:26 WST 2007 John Darrington + + * dictionary.c dictionary.h : Added replace_source and replace_dict + callbacks, and functions to deal with them. + Fri Dec 22 13:56:08 2006 Ben Pfaff Simplify missing value handling.
