[sqlite] sqlite3 fails due to too long path (MAX_PATHNAME)
Hi, I was testing long pathnames and ran into this failure: $ sqlite3 /tmp/loong/loong/loong/loong/aaa/x.db 'create table x(int y);' Error: unable to open database "/tmp/loong/loong/loong/loong/aaa/x.db": unable to open database file Tested with sqlite3 3.8.7.1 and 3.8.8.1 on Linux. This is due to: /* ** Maximum supported path-length. */ #define MAX_PATHNAME 512 According to http://pubs.opengroup.org/onlinepubs/009695399/basedefs/limits.h.html PATH_MAX should be at least 256 (sqlite is still good with that), but with XSI extensions PATH_MAX should be at least 1024 (_XOPEN_PATH_MAX) and sqlite3 fails there. Would it be possible to raise that limit, or output a better error message that says why it failed to open the file?

My suggestion would be to add something like this to sqliteLimit.h: /* ** Maximum supported path-length.. */ #ifndef SQLITE_MAX_PATH_LENGTH # define SQLITE_MAX_PATH_LENGTH 512 #endif and use that macro in os_unix.c in stead of the hardcoded '512' An amalgamation containing this (and an equivalent change in os_win.c) can be found here: http://cyqlite.sourceforge.net/cgi-bin/sqlite/tarball/cyqlite.tar.gz?uuid=trunk Hopefully, one day you will find this change (or something equivalent) in the official SQLite.

Maybe. open(2) should return ENAMETOOLONG. It is possible, though unlikely these days, that the shell's command-line limit is less than PATH_MAX, in which case the string passed to the sqlite3 binary would be truncated (and invalid). --jkl ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
