From: Heikki Linnakangas Date: Mon, 29 Jul 2024 17:38:19 +0000 (+0300) Subject: Remove dead generators for cyrillic encoding conversion tables X-Git-Tag: REL_18_BETA1~2274 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=679f940740f42f2401f72a6b95dc02b9c0ab3f30;p=thirdparty%2Fpostgresql.git Remove dead generators for cyrillic encoding conversion tables These tools were used to read the koi-iso.tab, koi-win.tab, and koi-alt.tab files, which contained the mappings between the single-byte cyrillic encodings. However, those data files were removed in commit 4c3c8c048d, back in 2003. These code generators have been unused and unusable ever since. The generated tables live in cyrillic_and_mic.c. There has been one change to the tables since they were generated in 1999, in commit f4b7624eb07a. So if we resurrected the original data tables, that change would need to be taken into account. So this code is very dead. The tables in cyrillic_and_mic.c, which were originally generated by these tools, are now the authoritative source for these mappings.
