From: Ben Pfaff Date: Sun, 6 Feb 2011 05:10:10 +0000 (-0800) Subject: sys-file-reader: Refactor to clean up character encoding support. X-Git-Tag: v0.7.7~31 X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8fdf0b4fa919e48397b438e9453d6b82215ff51;p=pspp-builds.git sys-file-reader: Refactor to clean up character encoding support. The system file format is unusual in that it does not record the encoding used by character strings at the beginning or at any fixed place in the file. Instead, it can be recorded practically anywhere in the file. It never precedes all of the actual character strings in the file, which makes it impossible to interpret those strings completely and correctly until it is encountered. Until now, the system file reader has dealt with this situation by stuffing uninterpreted character strings into data structures until the encoding is known, then at that point fetching out the character strings, reencoding them, and stuffing them back into the data structures. This does work, but it has the disadvantage that all of the PSPP data structures have to tolerate character strings with unknown encoding. In some cases this seems like an ugly situation. For example, arbitrary variable names have to be supported, even though the syntax for variable names is circumscribed by the language, because the syntax rules for variable names cannot be completely and correctly applied to a string that is in an unknown encoding. This commit fixes that problem by adopting a new way to read system files. Each record in the system file dictionary is essentially slurped into memory as a chunk, then the character encoding is extracted from it, then the rest of the dictionary is interpreted based on that encoding. The actual implementation is a little more intricate because the format of system file records is somewhat non-uniform. --- diff --git a/src/data/dictionary.c b/src/data/dictionary.c index 2ad94ca4..467f347e 100644 --- a/src/data/dictionary.c +++ b/src/data/dictionary.c @@ -1228,12 +1228,14 @@ dict_get_label (const struct dictionary *d) } /* Sets D's file label to LABEL, truncating it to a maximum of 60 - characters. */ + characters. + + Removes D's label if LABEL is null or the empty string. */ void dict_set_label (struct dictionary *d, const char *label) { free (d->label); - d->label = label != NULL ? xstrndup (label, 60) : NULL; + d->label = label != NULL && label[0] != '\0' ? xstrndup (label, 60) : NULL; } /* Returns the documents for D, or a null pointer if D has no diff --git a/src/data/sys-file-reader.c b/src/data/sys-file-reader.c index 8f39f478..ceb4e04f 100644 --- a/src/data/sys-file-reader.c +++ b/src/data/sys-file-reader.c @@ -1,5 +1,5 @@ /* PSPP - a program for statistical analysis. - Copyright (C) 1997-9, 2000, 2006, 2007, 2009, 2010, 2011 Free Software Foundation, Inc. + Copyright (C) 1997-2000, 2006-2007, 2009-2011 Free Software Foundation, Inc.
