1 2007-07-14 John Darrington <john@darrington.wattle.id.au>
3 * sfm-reader.c: Respect case_cnt field in file header.
5 2007-07-01 John Darrington <john@darrington.wattle.id.au>
7 * transformation.c transformation.h (trns_chain_execute): Changed the
8 signature (Patch #6057)
10 2007-06-10 Ben Pfaff <blp@gnu.org>
12 * casereader-filter.c (casereader_filter_destroy): Make sure to
13 write all the remaining excluded cases to the casewriter, if any.
15 * caseinit.c (init_list_destroy): Rewrite.
16 (init_list_clear): Ditto.
18 * casegrouper.c (casegrouper_get_next_group): Always set *reader
19 to null when returning false.
21 2007-06-06 Ben Pfaff <blp@gnu.org>
23 Actually implement the new procedure code and adapt all of its
24 clients to match. Also adapt all of the other case sources and
25 sinks in the tree and their clients to use the
26 casereader/casewriter infrastructure.
28 * automake.mk: Add and remove files.
30 * any-reader.c: Change into a casereader.
31 * por-file-reader.c: Ditto.
32 * scratch-reader.c: Ditto.
33 * sys-file-reader.c: Ditto.
35 * any-writer.c: Change into a casewriter.
36 * por-file-writer.c: Ditto.
37 * scratch-writer.c: Ditto.
38 * sys-file-writer.c: Ditto.
40 * procedure.c: Change to use casereader, casewriter, caseinit, and
41 other new infrastructure.
43 * scratch-handle.c: Adapt to new infrastructure.
45 * case-sink.c: Removed, now dead code.
47 * case-source.c: Ditto.
48 * case-source.h: Ditto.
49 * casefile-factory.c: Ditto.

53 * casefilter.c: Ditto.
54 * casefilter.h: Ditto.
57 * fastfile-factory.c: Ditto.
58 * fastfile-factory.h: Ditto.
59 * storage-stream.c: Ditto.
60 * storage-stream.h: Ditto.
62 2007-06-06 Ben Pfaff <blp@gnu.org>
66 * automake.mk: Add new files.
68 * datasheet.c: New file.
70 * datasheet.h: New file.
72 2007-06-06 Ben Pfaff <blp@gnu.org>
74 Until now, the procedure code has provided a case to the
75 case_source, which has filled in the data values that come from
76 the active file. "Left" data values that don't come from the
77 active file naturally stay the same from case to case, because the
78 procedure code keeps using that same case.
80 One of the compromises that comes with the new procedure code is
81 that the active file allocates and provides its own case, which
82 the procedure code then has to resize to provide room for any
83 other variables that should go in the case and then fill in the
84 values of "left" variables. Then, when we're done with that case,
85 we have to save the values of "left" variables to copy into the
86 next case read from the active file.
88 The caseinit code helps with this.
90 * automake.mk: Add new files.
92 * caseinit.c: New file.
94 * caseinit.h: New file.
96 2007-06-06 Ben Pfaff <blp@gnu.org>
98 * value.h (value_cnt_from_width): New function.
100 * variable.c (var_get_value_cnt): Use new function.
102 2007-06-06 Ben Pfaff <blp@gnu.org>
104 Add casegrouper, to allow cases read from a given casereader to be
105 broken into groups, each of which has its own casereader.
106 Generally cases are grouped based on having equal values for some
109 * automake.mk: Add new files.
111 * casegrouper.c: New file.
113 * casegrouper.h: New file.
115 2007-06-06 Ben Pfaff <blp@gnu.org>
117 Add interface to lexicographical ordering of cases.
119 * automake.mk: Add new files.
121 * case-ordering.c: New file.
123 * case-ordering.h: New file.
125 2007-06-06 Ben Pfaff <blp@gnu.org>
127 Add casereaders and casewriters, the basis of the new data processing
128 implementation. A casereader is a uniform interface to reading cases
129 from a data source; a casewriter is a uniform interface to writing
130 cases to a data sink.
132 * automake.mk: Add new files.
134 * casereader-filter.c: New file.
136 * casereader-provider.h: New file.
138 * casereader-translator.c: New file.
140 * casereader.c: New file.
142 * casereader.h: New file.
144 * casewriter-provider.h: New file.
146 * casewriter-translator.c: New file.
148 * casewriter.c: New file.
150 * casewriter.h: New file.
152 2007-06-06 Ben Pfaff <blp@gnu.org>
154 "casewindow" data structure that extends the deque (from libpspp)
155 of cases with the ability to dump cases to disk if we get too many
158 * automake.mk: Add new files.
160 * casewindow.c: New file.
162 * casewindow.h: New file.
164 2007-06-06 Ben Pfaff <blp@gnu.org>
166 sparse_cases data structure that augments a sparse_array of cases
167 with the ability to dump cases to disk if we get too many cases in
170 * automake.mk: Add new files.
172 * sparse-cases.c: New file.
174 * sparse-cases.h: New file.
176 2007-06-06 Ben Pfaff <blp@gnu.org>
178 Adds a low-level on-disk case array data structure.
180 * automake.mk: Add new files.
182 * case-tmpfile.c: New file.
184 * case-tmpfile.h: New file.
186 2007-06-06 Ben Pfaff <blp@gnu.org>
188 In a couple of places we calculate the maximum number of cases to
189 keep in memory based on the user-defined workspace. Enable
190 centralizing the calculation through a new function.
192 * settings.c (get_workspace_cases): New function.
194 2007-06-06 Ben Pfaff <blp@gnu.org>
196 The casenumber type is defined in transformations.h, but case.h is
197 a more sensible place. Move it.
199 * case.h (CASENUMBER_MAX): New macro.
200 (typedef casenumber): Move here, from transformations.h.
202 2007-06-03 Ben Pfaff <blp@gnu.org>
204 Slightly generalize case_to_values and case_from_values functions.
206 * case.c (case_to_values): Rename case_copy_out, change interface.
207 (case_from_values): Rename case_copy_in, change interface.
209 * fastfile.c (fastfilereader_get_next_case): Update caller.
210 (write_case_to_disk): Ditto.
212 2007-06-02 Ben Pfaff <blp@gnu.org>
214 Clean up after a forgotten part of patch #5829.
216 * casedeque.h: Remove unused file.
218 * automake.mk: Remove casedeque.h from sources.
220 2007-05-10 Jason Stover <jhs@math.gcsu.edu>
222 * category.c: Removed redundant #include
224 2007-05-06 Ben Pfaff <blp@gnu.org>
226 Abstract the documents within a dictionary a little better.
227 Thanks to John Darrington for suggestion, initial version, and
230 * dictionary.c (struct dictionary): Change `documents' member from
231 char * to struct string.
232 (dict_clear): Destroy struct string.
233 (dict_get_documents): Convert struct string to char *.
234 (dict_set_documents): Set struct string. Pad to 80-character
236 (dict_clear_documents): New function.
237 (dict_add_document_line): New function.
238 (dict_get_document_line_cnt): New function.
239 (dict_get_document_line): New function.
241 * dictionary.h (macro DOC_LINE_LENGTH): New macro.
243 * sys-file-reader.c (read_documents): Use new document functions.
245 2007-04-19 John Darrington <john@darrington.wattle.id.au>
247 * sys-file-reader.c: When reading a system file which has no
248 long name table, automatically create one where the long names
249 are the lower case versions of the short names.
251 2007-04-22 Ben Pfaff <blp@gnu.org>
253 * dictionary.c (dict_set_split_vars): dict_destroy expects that
254 dict_clear will free most data related to the dictionary.
255 dict_clear does a decent job, except that dict_set_split_vars on
256 some systems won't actually free the dict's "split" member.
257 Instead, it'll allocate a 1-byte region. Fix this.
259 * value.c (value_copy): New function.
260 (value_set_missing): Ditto.
262 2007-04-22 John Darrington <john@darrington.wattle.id.au>
264 * Deleted existing category.h and moved cat-routines.h into
265 category.h Encapsulated struct cat_vals better.
267 2007-04-19 John Darrington <john@darrington.wattle.id.au>
269 * sys-file-reader.c: When reading a system file which has no
270 long name table, automatically create one where the long names
271 are the lower case versions of the short names.
273 2007-04-16 John Darrington <john@darrington.wattle.id.au>
275 * sys-file-reader.c: Some versions of Other Software seem to
276 produce system files with string variables' measure set to
277 zero. We'll assume these are supposed to be nominal variables.
279 2007-03-30 Ben Pfaff <blp@gnu.org>
281 * procedure.c: Adapt to new deque data structure.
283 Mon Feb 19 10:53:21 2007 John McCabe-Dansted <gmatht@gmail.com>
284 Ben Pfaff <blp@gnu.org>
286 * file-name.c: Mingw compatibility fixes.
287 (fn_search_path): Use ISSLASH instead of comparing against '/'
289 (fn_dir_name): Use dir_name from gnulib.
290 (fn_is_absolute): Use IS_ABSOLUTE_FILE_NAME from gnulib.
291 (fn_get_identity): Use GetFullPathName instead of canonicalize
292 from gnulib, because the latter does not fully support
293 Windows-style path names. Use this implementation based on the
294 detected presence of Windows instead of the absence of Unix, since
295 the new implementation is Windows-specific.
296 (fn_compare_file_identities): In Windows implementation, compare
297 names case-insensitively.
299 Sun Feb 18 13:28:02 2007 Ben Pfaff <blp@gnu.org>
301 * make-file.c: Don't include mkstemp.h, because gnulib now causes
302 <stdlib.h> to have the same effect.
304 Sun Feb 18 11:20:24 2007 Ben Pfaff <blp@gnu.org>
306 * por-file-reader.c: Add missing _() around messages.
308 Sun Feb 11 20:44:13 2007 Ben Pfaff <blp@gnu.org>
310 * make-file.c: Include "mkstemp.h", without which linking on
313 Thu Feb 8 14:59:05 2007 Ben Pfaff <blp@gnu.org>
315 Reduce platform dependence.
317 * file-name.c (fn_tilde_expand): Removed, and removed calls to it.
318 Everywhere we using this, we really should have just depended on
319 the shell to expand tildes.
320 (fn_search_path): Simplify, given that we don't do tilde expansion
322 (fn_normalize): Removed. Caller changed to use the canonicalize
324 (fn_get_cwd): Removed. Only user was fn_normalize.
325 (fn_is_absolute): Really only test for absolute names.
326 (fn_is_special): Use pipe files if HAVE_POPEN, not if we're in
328 (fn_readlink): Removed, as it was only used fn_normalize.
329 (fn_exists): Assume the stat function is available; gnulib does.
330 (fn_open): Use pipe files if HAVE_POPEN, not if we're in unix.
332 Sat Feb 3 21:52:17 2007 Ben Pfaff <blp@gnu.org>
334 * dictionary.c (dict_create_vector_assert): New function.
336 Wed Feb 7 21:25:15 2007 Ben Pfaff <blp@gnu.org>
338 * file-name.c (fn_normalize): Correct name of function
339 fn_is_special. Thanks to John McCabe-Dansted <gmatht@gmail.com>
340 for pointing this out.
342 Thu Feb 1 16:53:37 2007 Ben Pfaff <blp@gnu.org>
344 We are using a single member in struct file_handle, the "name"
345 field, for more than one purpose. When it begins with '"', it's a
346 file name; otherwise, it's a token that can be used to identify
347 it. When that assertion fires, it's because we searched for the
348 name case-sensitively as a file name (so that there was no match),
349 and then we try to insert it case-insensitively as a token, which
350 fails because duplicates aren't allowed.
352 Solution: break the two purposes into two separate fields. This
353 fixes the problem and likely makes the code easier to read too.
355 Fixes bug #18922. Thanks to John Darrington for bug report and
358 * file-handle-def.c (struct file_handle): New `id' member.
359 (fh_from_name): Rename fh_from_id. Update all callers.
360 (create_handle): New `id' parameter. Update all callers.
361 (fh_create_file): Ditto.
362 (fh_get_id): New function.
364 Mon Jan 15 16:18:10 2007 Ben Pfaff <blp@gnu.org>
366 * case.c (case_is_null): Change return type to bool.
368 Mon Jan 15 10:57:28 2007 Ben Pfaff <blp@gnu.org>
372 * case.c (case_clone) [DEBUGGING]: When debugging, don't use
373 reference counting to share data. This makes it easy for
374 valgrind, etc. to find accesses to cases that have been destroyed
375 but have been kept around by another user's ref-count. This often
376 happens when the data set is small enough to find in memory; if a
377 bigger data set that would overflow to disk were used, then data
378 corruption would occur.
380 Mon Jan 15 10:55:18 2007 Ben Pfaff <blp@gnu.org>
384 * case.c (case_unshare): Make it check internally whether the
385 ref_cnt is greater than 1, so that the callers don't have to.
386 Update callers not to check.
388 Mon Jan 15 10:53:01 2007 Ben Pfaff <blp@gnu.org>
390 Before, I was thinking that I might want to get rid of reference
391 counting at some point. Now, I'm pretty sure that it's here to
392 stay. Thus, because we have to store the value_cnt anyway for
393 reference-counted cases, we might as well expose it to users.
395 * case.c (case_get_value_cnt): New function.
396 (case_resize): Drop OLD_CNT argument. Update all callers. Only
397 resize case if its size actually changed.
399 * casefile.c (casefile_append_xfer): Use case_get_value_cnt
400 instead of peeking inside struct case directly.
401 (casefile_append): Ditto.
403 Mon Jan 15 10:50:22 2007 Ben Pfaff <blp@gnu.org>
405 Get rid of the inlines for the case functions, which made the
406 header file hard to read. (Also, in testing with "-O2 -DNDEBUG",
407 the inlines didn't speed up "make check" at all, which is not a
408 perfect benchmark but seems indicative.)
410 * case.c: Remove #ifdef DEBUGGING...#endif around many function
411 definitions. Remove some assertions on nonnull pointers that were
412 redundant with a pointer dereference soon after in the function.
414 (struct case_data): Move definition here from case.h.
418 (case_data_wr): Ditto.
420 Sun Jan 14 21:41:12 2007 Ben Pfaff <blp@gnu.org>
422 * automake.mk: Add casedeque.h to sources.
424 * casedeque.h: New file.
426 * procedure.c: (struct dataset) Change lag_count, lag_head,
427 lag_queue member into single struct casedeque member. Update all
428 users to use the casedeque instead.
431 Sun Jan 14 21:43:12 2007 Ben Pfaff <blp@gnu.org>
433 * procedure.c: Simplify lagged cases interface. Updated all
434 clients--well, the only client--to use the simplified interface.
435 (dataset_n_lag) Removed.
436 (dataset_set_n_lag) Removed.
437 (dataset_need_lag) New function.
439 Tue Jan 9 07:20:05 WST 2007 John Darrington <john@darrington.wattle.id.au>
441 * dictionary.c procedure.c: More changes to ensure that callbacks occur
442 whenever appropriate, but only when the dataset/dictionary is in a
445 Sun Jan 7 08:33:04 WST 2007 John Darrington <john@darrington.wattle.id.au>
447 * dictionary.c dictionary.h : Added callbacks for change of filter and
448 split variables. Refactored some code to ensure that callbacks get
449 invoked when appropriate.
451 * procedure.c (proc_cancel_temporary_transformations): Make sure that
452 replace_dict callback occurs when permanent_dict replaces the current
455 Wed Jan 3 11:02:11 WST 2007 John Darrington <john@darrington.wattle.id.au>
457 * dictionary.c dictionary.h : Added callback for when the weight
458 variable of a dictionary changes.
460 Mon Jan 1 10:36:26 WST 2007 John Darrington <john@darrington.wattle.id.au>
462 * dictionary.c dictionary.h : Added replace_source and replace_dict
463 callbacks, and functions to deal with them.
465 Fri Dec 22 13:56:08 2006 Ben Pfaff <blp@gnu.org>
467 Simplify missing value handling.
469 * missing-values.h (enum mv_class): New type.
470 (enum mv_type): Moved definition into missing-values.c and renamed
471 each MV_* to MVT_*, to distinguish them from the exposed mv_class
472 enums. Updated all uses.
473 (struct missing_values): Changed type of `type' from `enum
474 mv_type' to `int' because the definition is no longer exposed.
476 * missing-values.c (mv_is_value_missing): Add new enum mv_class
477 parameter. Update all callers.
478 (mv_is_num_missing): Ditto.
479 (mv_is_str_missing): Ditto.
480 (mv_is_value_user_missing): Removed. Changed callers to use
482 (mv_is_num_user_missing): Removed. Changed callers to use
484 (mv_is_str_user_missing): Removed. Changed callers to use
486 (mv_is_value_system_missing): Removed. Changed callers to use
488 (mv_set_type): Removed. Changed callers to use mv_clear.
489 (mv_clear): New function.
491 * variable.c (var_is_value_missing): Add new enum mv_class
492 parameter. Update all callers.
493 (var_is_num_missing): Ditto.
494 (var_is_str_missing): Ditto.
495 (var_is_value_user_missing): Removed. Changed callers to use
496 var_is_value_missing.
497 (var_is_num_user_missing): Removed. Changed callers to use
499 (var_is_str_user_missing): Removed. Changed callers to use
501 (var_is_value_system_missing): Removed. Changed callers to use
502 var_is_value_missing.
504 * casefilter.c (struct casefilter): Use enum mv_class in place of
506 (casefilter_variable_missing): Adapt to new member.
507 (casefilter_create): Change signature to take enum mv_class,
510 Fri Dec 22 20:08:38 WST 2006 John Darrington <john@darrington.wattle.id.au>
512 * casefile-factory.h fastfile-factory.c fastfile-factory.h: New files.
514 * case-sink.c case-sink.h procedure.c procedure.h
515 storage-stream.c: Now uses the factory.
517 Sat Dec 16 22:05:18 2006 Ben Pfaff <blp@gnu.org>
519 Make it possible to pull cases from the active file with a
520 function call, instead of requiring indirection through a callback
523 * case-source.h (struct case_source_class): Change ->read function
524 to return a single case, instead of calling a callback function
525 for each case. Change ->destroy function to return an error
528 * case-source.c (free_case_source): Pass along the value returned
529 by the case_source ->destroy function.
531 * procedure.c (struct write_case_data): Removed.
532 (struct dataset): Added some members to track procedure state.
533 (procedure): Optimize the trivial case at this level.
534 (internal_procedure): Re-implement in terms of proc_open,
535 proc_read, proc_close.
536 (proc_open) New function.
537 (proc_read) New function.
538 (proc_close) New function.
539 (write_case) Moved into proc_read.
540 (close_active_file) Moved closing of data source into proc_close.
542 * storage-source.c: Rewrote to conform with modified
543 case_source_class interface.
545 * transformations.c (trns_chain_execute): Added argument to allow
546 starting execution from an arbitrary transformation. Updated
549 * transformations.h (enum TRNS_NEXT_CASE) Renamed TRNS_END_CASE.
551 Sat Dec 16 14:09:25 2006 Ben Pfaff <blp@gnu.org>
553 * sys-file-reader.c (read_display_parameters): Don't assume that
554 MEASURE_* and ALIGN_* have the same values found in system files.
556 * sys-file-writer.c (write_variable_display_parameters): Ditto.
558 * variable.h: Change MEASURE_NOMINAL, MEASURE_ORDINAL,
559 MEASURE_SCALE to be 0-based instead of 1-based. This also fixes
560 the value of n_MEASURES, which was off by 1 (at least from my
563 Sat Dec 16 12:17:34 WST 2006 John Darrington <john@darrington.wattle.id.au>
565 * dictionary.c dictionary.h vardict.h variable.c: Added optional
566 callbacks which are invoked when the dictionary or its
567 variables are changed.
569 * missing-values.c missing-values.h value-labels.c: Tidied up
570 consistency checks, and made some of them return false
571 instead of assert-failing.
573 Wed Dec 13 19:30:11 2006 Ben Pfaff <blp@gnu.org>
575 * calendar.c (calendar_days_in_month): New function.
577 Mon Dec 11 07:53:39 2006 Ben Pfaff <blp@gnu.org>
579 * value-labels.c (hash_int_val_lab): Only hash as many bytes as
580 the value label's width.
582 Sun Dec 10 14:21:29 2006 Ben Pfaff <blp@gnu.org>
584 * sfm-private.h: Move contents into sys-file-writer.c, which is
585 the only remaining user. Removed Borland C++-specific directives.
587 * sys-file-reader.c: Clean up and rewrite entire file. The
588 rewritten version is simpler and better abstracted, and should be
589 easier to maintain and extend. It avoids using structures to read
590 file data, which is prone to padding variations among compilers.
591 It should also handle non-IEEE 754 system files, although I
592 haven't been able to find any. It has been tested against many
593 .sav files obtained from the Web and found to produce the same
594 results as the earlier version of the code, or in some cases
595 improved results. It is more tolerant of format variations found
598 * sys-file-reader.h (struct sfm_read_info): Removed `big_endian'
599 member, putting an enum integer_format in its place. New member
600 `float_format'. Changed `compressed' member to type bool.
602 Sun Dec 10 13:48:53 2006 Ben Pfaff <blp@gnu.org>
604 * dictionary.c (dict_delete_consecutive_vars): New function.
606 Sat Dec 9 20:08:25 2006 Ben Pfaff <blp@gnu.org>
608 * file-name.c (fn_search_path): Remove prefix arg that was unused
609 by any caller. Updated all callers.
611 Sat Dec 9 20:04:22 2006 Ben Pfaff <blp@gnu.org>
613 * format.c (fmt_dollar_template): Use user's decimal point
614 character. Add assertion.
616 Sat Dec 9 20:02:25 2006 Ben Pfaff <blp@gnu.org>
618 * format.c (fmt_dollar_template): New function, based on

626 Sat Dec 9 17:23:23 2006 Ben Pfaff <blp@gnu.org>
628 Finish converting struct variable to an opaque type. In this
629 phase, we add remaining setter and getter functions, convert the
630 remaining PSPP code to use them, and do a bunch of cleanup. The

650 * category.c (cat_stored_values_destroy): Changed interface to
651 take a struct cat_vals * instead of a struct variable *.

690 * sys-file-writer.c: Ditto.
692 * value-labels.c: Change the paradigm here to be that a null

696 (val_labs_count) A null set has 0 labels.
697 (val_labs_replace) Change return type to void. Rewrite for

1089 Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
1090 ALL) and additional underlying system file issues.
1092 Thanks to John Darrington for review.
1094 First problem: var_hash points to variables not owned by the
1095 sys-file-reader, which the caller may free or modify. Use an
1096 array of sfm_vars instead, as done earlier (e.g. CVS version
1099 * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
1100 members and remove all code that references it. Add vars, var_cnt
1101 members. Remove fix_specials member, which was unused.
1102 (struct sfm_var) Remove name member, which was unused.
1103 (sfm_close_reader) Free vars member instead of var_hash.
1104 (compare_var_shortnames) Removed.

1106 (sfm_open_reader) Fill out vars array.
1107 (compare_var_index) Removed.
1108 (sfm_read_case) Use vars instead of var_hash.
1110 Second problem: we're confused about when we actually have very
1111 long strings, causing us to choose incorrectly between slow path
1112 and fast path in sfm_read_case.
1114 * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
1115 have very long strings, not when we have long variable names,
1116 which is an unrelated feature.
1118 Tue Jun 27 12:06:49 2006 Ben Pfaff <blp@gnu.org>
1120 * variable.h: Move var_set and variable parsing declarations to
1121 new header, src/language/lexer/variable-parser.h. Modified lots
1122 of files to include the new header.
1124 Sun Jun 25 22:39:32 2006 Ben Pfaff <blp@gnu.org>
1126 * value-labels.c (value_to_string): When there's no value label,
1127 format the variable according to its print format, instead of
1128 always effectively using A or F format.
1130 Mon Jun 19 18:05:42 WST 2006 John Darrington <john@darrington.wattle.id.au>
1132 * casefile.c (casefile_get_random_reader): Nasty hack to get around

1302 procedures instead. This also adds some flexibility.
1304 Updated many users of procedure_with_splits() and
1305 multipass_procedure_with_splits() to call

1461 * variable.h: (struct variable) Remove `init' member and all
1462 references to it from other files. It was initialized in several
1463 places, but nothing really ever used it for anything worthwhile.
1464 Thanks to Jason Stover for pointing out how confusing this
1467 Sun Apr 23 22:04:45 2006 Ben Pfaff <blp@gnu.org>
1469 Continue reforming error message support. In this phase, get rid
1470 of message "titles" and put the message text in `struct error'.
1471 Now `struct error' encapsulates a message more properly.
1473 * casefile.c: (io_error) Use err_msg() instead of err_vmsg().

1495 Sun Apr 16 18:35:33 2006 Ben Pfaff <blp@gnu.org>
1497 We don't really support anything but Unix-like environments well,
1498 so we might as well de-obfuscate by writing directory and path
1499 separators explicitly.
