This is the second of a series of changes related to save/restore.
No EDITLEVEL bump has been included, because although the code
is changed extensively by this, the content of the savefiles have
not been changed.
Push the use of the structlevel bwrite() and mread() function use
out of the core and into sfstruct.c. This is groundwork for upcoming
changes.
In the core, replace the bwrite() and mread() calls with the
use of type-specific savefile output (Sfo) and savefile
input (Sfi) macros. The macros are defined in a new header file
savefile.h, which also contains the prototypes for the sfo_* and
sfi_* functions that the macros ultimately expand to. The functions
themselves are in src/sfbase.c.
On C99, each Sfo or Sfi macro expansion refers directly to the
corresponding type-specific sfo_* or sfi_* function.
If C23 or later is is use, the majority (all but 3 types) of the
macros refer to a single _Generic output routine sfo(nhfp, dt, tag),
and a single _Generic input routine sfi(nhfp, dt, tag), which handles
the dispatch of the type-specific underlying functions. This was
somewhat experimental, but turned out to be practical because the
compiler would gripe if the type for a variable was not included in
the _Generic when passed as an argument, so it could be fixed.
This alters the savefile verication process by having a common set
return values for the related functions such as uptodate(),
check_version(), etc. The new return values return more information
about savefile incompatibilities, beyond failure/sucess. The
additional information will be useful for an upcoming addition.
The expanded return values are:
SF_UPTODATE (0) everything matched and looks good
SF_OUTDATED (1) savefile is outdated
SF_CRITICAL_BYTE_COUNT_MISMATCH (2) critical size count mismatch
SF_DM_IL32LLP64_ON_ILP32LL64 (3) Windows x64 savefile on x86
SF_DM_I32LP64_ON_ILP32LL64 (4) Unix 64 savefile on x86
SF_DM_ILP32LL64_ON_I32LP64 (5) x86 savefile on Unix 64
SF_DM_ILP32LL64_ON_IL32LLP64 (6) x86 savefile on Windows x64
SF_DM_I32LP64_ON_IL32LLP64 (7) Unix 64 savefile on Windows x64
SF_DM_IL32LLP64_ON_I32LP64 (8) Windows x64 savefile on Unix 64
SF_DM_MISMATCH (9) some other mismatch
The callers in the core have been adjusted to deal with the expanded
return values.
Other miscellaneous inclusions:
- go.oracle_loc -> svo.oracle_loc.
- add a bit (1UL << 30) to called SFCTOOL_BIT as groundwork
for changes to follow.
In sys_early_init(), the values for sysopt.gdbpath and
sysopt.greppath were being assigned by calling dupstr()
without ensuring that a value previously assigned by
dupstr() were free()'d.
Also, the sysopt struct definition is changed to sysopt_s,
not because there's anything wrong with the original
struct sysopt sysopt;
but because I couldn't convince the debugger to use the
correct thing when trying to track down the leak.
Check getenv("DEBUGFILES") unconditionally during startup rather
than waiting until it's needed.
Might prevent the static analyzer from getting so aggravated.
Most likely not though, but should make debugpline() less fragile
if it gets called during a panic or a signal.
When calling panic() or impossible(), create the option
of opening a browser window with most of the fields
already populated. Code for MacOS and linux is included;
other ports are affected by argument change to early_init
which are done but not tested.
To enable, define CRASHREPORT in config.h and set
CRASHREPORTURL in sysconf to (for the moment at least)
http[s]://www.nethack.org/common/contactcr.html
Adds --grep-defined option to makedefs for Makefiles.
Adds "bid" (binary identifier), an MD4 of the main nethack
binary. This is ONLY for helping (in the future) contact.html
to set the "NetHack from" field automatically for our own
binaries. This can be faked, but the user can lie so nothing
lost. There's nothing magic about MD4; other ports can use
anything that prodcues a long apparently random string we can
match against.
- new option --bidshow for us to get the MD4 of a
released binary so I can add it to the website.
Only available in wizard mode and not in nethack.6.
- typo macos -> macosx in hints file
No support for packaging builds as I'm not sure what that
would look like.
Adds a javascript helper for MacOS.
Adds a lua helper for linux (and builds and installs
nhlua).
Instead of using a compile-time macro to suppress inclusion of the
menu entry to show UNIX command-line usage in the help menu, use a
sysconf setting instead.
Default is HIDEUSAGE=0, to include the entry for command-line usage.
Set HIDEUSAGE=1 to exclude that. Does not affect 'nethack --usage'
if player actually has access to the command-line.
Log game events, such as entering a new dungeon level, breaking
a conduct, or killing a unique monster, in a new "Major events"
chronicle. The entries record the turn when the event happened.
The log can be viewed with #chronicle -command, and the entries
also show up in the end-of-game dump, if that is available.
This feature is on by default, but can be disabled by
defining NO_CHRONICLE compile-time option.
This also contains "live logging", writing the events as they
happen into a single livelog-file. This is mostly useful for
public servers. The livelog is off by default, and must be
compiled in with LIVELOG, and then turned on in sysconf.
Mostly this a version of livelogging from the Hardfought server,
with some changes.
Allow a way to configure NetHack to run entirely from a USB stick
or other removable device in a way that allows everything to
reside entirely on the USB stick, and nothing on the computer's
hard drive. That could be done in versions prior to 3.6.3.
Sample:
i: is a USB stick
i:\nhdist contains the NetHack Windows distribution and a sysconf
file dropped into that distribution with the following entry in it:
portable_device_top = nethack
No device is included in the portable_device_top entry, the device
is always the device that the nethack exe resides on. If you try
to specify a device in the portable_device_top path, the device
portion will be ignored.
portable_device_top specifies the folder on the device that is writable
by NetHack and as such it cannot be the same folder that the executable
resides in.
i:\nhdist\nethack --showpaths

Without that sysconf file in the NetHack distribution folder on the

return to the default locations for 3.6.3 on Windows:

Changing from BETA to RELEASED resulted in turning off PANICTRACE
and that exposed a minor memory leak. Only applies to program exit
so doesn't impact play.
A few symbol-related modifications:
- fulfill a request from a blind player to allow them to
specify a unique/recognizable character for all pets and/or
the player in the config file for use when using a screen
reader (S_player_override, S_pet_override). Requires sysconf
setting ACCESSIBILITY to be set to have an effect, although
they can still be specified in the config file.
- Config file SYMBOLS entries were not working properly on
the rogue level. Allow ROGUESYMBOLS as well as SYMBOLS to be
specified in the config file independently.
- When values are moved into showsyms[], the overriding SYMBOLS
or ROGUESYMBOLS entry from the config file is used if there is
one; if there is no overriding value for a particular symbol,
the loaded symset value is used; if there is no symset entry
loaded for the symbol then a default symbol is used.
When SEDUCE is disabled, instead of swapping attacks in mons[] once,
do it on the fly in getmattk() whenever needed. That allows mons[]
to become readonly, although this doesn't declare it 'const' because
doing so will require a zillion 'struct permonst *' updates to match.
This seemed trickier than it should be, but that turned out to be
because the old behavior was broken. Setting SEDUCE=0 in sysconf or
user's own configuration file resulted in all succubus and incubus
attacks being described as monster smiles engagingly or seductively
rather than hitting (while dishing out physical damage). I didn't
try rebuilding 3.4.3 to see whether this was already broken before
being migrated to SYSCF.
Reduce the chance of a player playing on a public server encountering
their own bones, by implementing separate bones pools. The pool a player
belongs to is determined at game start, and only bones in that pool
are used. The sysconf BONES_POOLS allows the sysadmin to define how
many pools there are.
Setting CHECK_PLNAME to 1 makes WIZARDS, EXPLORERS, and SHELLERS
check the player name instead of the user's login name.
This is mostly useful for public servers which have external
login system and don't create user accounts for players.
Preformat SYSCF entry 'WIZARDS' so that it can be displayed during panic
feedback without allocating memory for the formatted list at that time.
It also gets displayed for help's "support information" ('?k').
For panic(), push "it may be possible to rebuild" to a second line since
the formatted usernames might make the line long.
Free sysopt.shellers and sysopt.explorers when releasing the memory used
for other sysopt fields.
Also some formatting stuff since sys.c was previously untouched.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!
If getenv("DEBUGFILES") yields a value then it takes precedence over
sysconf.DEBUGFILES or sys.c's #define DEBUGFILES. (It probably should
only be controlled via environment since it is not a system-wide
attribute, but I haven't taken out the SYSCF handling for it.)
* Replace variadic debugpline() with fixed argument debugpline0(str),
debugpline1(fmt,arg), and so on so that C99 support isn't required;
* showdebug() becomes a function rather than a macro and handles a
bit more;
* two debugpline() calls in light.c have been changed to impossible();
* DEBUGFILES macro (in sys.c) can substitute for SYSCF's DEBUGFILES
setting in !SYSCF configuration (I hope that's temporary).
Move debugging output into couple preprocessor defines, which
are no-op without DEBUG. To show debugging output from a
certain source files, use sysconf:
DEBUGFILES=dungeon.c questpgr.c
Also fix couple debug lines which did not compile.
This also includes fixes due to Derek Ray to depugpline to work better
on other platforms.
