check both EAGAIN and EWOULDBLOCK. These are distinct on some
systems, e.g. HP-UX.
(io_output) [hpux]: Used to treat all errors as EWOULDBLOCK. This
looks like a inept attempt to `fix' the above. Remove.
(PTR_CACHE): Rename.
(ARRAY_CACHE): New.
(empfile): Use it to set csize of elements EF_SHIP_CHR, EF_PLANE_CHR,
EF_LAND_CHR, EF_NUKE_CHR.
(ef_init_chr): Now that empfile[]'s initializer sets csize, remove the
temporary csize initialization here. The value wasn't correct, but
better than nothing.
members.
(empfile): Reorder members for clearer documentation.
(EFF_IMMUTABLE): New.
(EFF_OPEN): Remove, use ~EFF_IMMUTABLE.
(empfile): Don't initialize member size to a useless value for EF_MAP
and EF_BMAP. ef_init() writes the real value.
one of its prefixes. src/lib/global/file.c rev. 1.18 added such table
entries, and file.h rev. 1.34 made them visible to ef_byname().
Simply use stmtch(). This also rejects ambiguous abbreviations: "s"
used to return EF_SECTOR, it now returns M_NOTUNIQUE.
(set, mission, multifire, fuel, cons_choose, cede): Use it instead of
ef_byname(). Remove the hacks to map unwanted results to wanted
results. The hacks in set() were broken: bad input made the code cast
arbitrary items to union trdgenstr, with potentially disastrous
consequences. Closes#906483 and #906486.
(set): Less cryptic prompt and diagnostics.
(ef_read): Used to get the file size again some circumstances; doesn't
make sense, as no other process may be writing this file.
(ef_write): Don't refuse to write beyond record 65536. This module
can cope with that. Some users have trouble long before that (short
record numbers), but that should be handled there.
(ef_write): Catch table not file-backed.
Catch negative count; used to have no effect with EFF_MEM, and
confusion otherwise. Try to recover from partially successful
extension. Need help from ef_write() to do a better job; to be done.
file descriptors.
(ef_flush, ef_close): Rely on negative fd instead of null cache to
detect unopened file. This is more logical and consistent with the
use of cache by the new tables that are not file-backed (rev. 1.22).
Use CANT_HAPPEN().
(ef_close): Failed to report cash flush failure.
(ef_close): Clear all EFF_OPEN flags. Should have been done in
rev. 1.27.
(ef_flush, ef_write): Use it. Old code couldn't cope with interrupted
or short writes (mostly harmless, as disk reads commonly complete).
(ef_write): Use CANT_HAPPEN() for catching unimplemented table
extensions.
couldn't cope with interrupted or short reads (mostly harmless, as
disk reads commonly complete), and left an empty cache after a failed
read.
(ef_open): Use fillcache() instead of read().
(ef_read): Fail if fillcache() fails to read at least one element.
Old version copied garbage to its caller and claimed success.
(really open flags, not mode) by new flags EFF_RDONLY, EFF_CREATE.
Open flags were needlessly general. Callers changed.
(empfile): Member mode now unused, remove.
user sees the new elements of empfile[].
(EF_SECTOR_CHR, EF_SHIP_CHR, EF_PLANE_CHR, EF_LAND_CHR, EF_NUKE_CHR)
(EF_TREATY_CHR, EF_ITEM, EF_INFRASTRUCTURE, EF_PRODUCT): New. Not yet
used.
(my_ef_byname): Replacement for ef_byname() that sees the new
elements.
(xdchr): Work with empfile[] instead of chr_camap[].
(xdump): Use my_ef_byname() instead of ef_byname() and
chridx_by_name().
(camap, chr_camap, chridx_by_name): Remove.
