Subject: patch 9.2.0690: Solaris: swap file names are too long
X-Git-Tag: v9.2.0690^0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e2196f85009201bf547db330537585a38968262a;p=thirdparty%2Fvim.git

patch 9.2.0690: Solaris: swap file names are too long

Problem:  Solaris: dirent.h exposes MAXNAMLEN as 512, but the usable
          file name component limit is 255 (defined in param.h).  Vim
          derives BASENAMELEN for generated swap file names from
          MAXNAMLEN, so it creates overlong components and fails to
          rename the swap file with ENAMETOOLONG (Vladimír Marek).
Solution: Override MAXNAMLEN to the effective Solaris component limit
          of 255 for swap file name generation.

closes: #20573
