* Correctly construct empty lists in dbm_page_get().Ingo Schwarze2018-11-191-3/+3
| | | | | | | | | | Original commit message by the author of this bugfix patch, bluhm@: lstmatch() expects a list of strings separated by \0 and terminated with \0\0. In the NULL case dbm_page_get() returned only simple strings so correct processing was depending on data layout. Use an additional \0 to terminate the single string lists. Found by mandoc regress since llvm linker on amd64 arranges strings differently.
* The termination condition of the iteration logic in page_bymacro()Ingo Schwarze2016-10-181-18/+22
| | | | | | | was overzealous. Consequently, macro=substr and macro~regexp searches only returned all pages containing the first matching macro value, rather than all pages containing any of the matching macro values. Bug reported by tb@ - thanks!

Similar patches will be needed for the macro tables, too. <attila at stalphonsos dot com> audited the code and pointed out to me that dbm_get() can return NULL for corrupted databases, but that isn't handled properly at various places.

Stop supporting systems that don't have mmap(3). Drop the obsolete names_check() now that we deleted MLINKS.
