(ITS#8558) LMDB mdb_load plain text

Full_Name: Remy Chibois Version: LMDB_0.9+ OS: Debian "Jessie" URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (46.218.8.100)

when loading data into a LMDB database using plain text mode (mdb_load -T), escaped hexadecimal pairs (such as \09 for a tab character) cause data to be incorrectly converted.

Replacing mdb_load.c line 251 with "*c1++ = *c2++;"nsnstead of "c1++; c2++;" fixes the issue (after the first escaped sequence, characters from c2 pointer need to be copied to c1 pointer in order to properly overwrite escaped sequence).
