[gtk-gnutella-announce] GTKG 1.1.7 has been released

[Raphael M. <Rap...@po...>]

Dear Gnutella fans,

Here is the ChangeLog for the 1.1.7 version which has just been released.

# v 1.1.7   2015-12-13  [stable]

This release adds support for new features:

	- TLS upgrade of existing connections.
	- Inbound HTTPS connections
	- Use of a supervisor process to relaunch gtk-gnutella on crashes

The TLS upgrade allows connections that have started without TLS to negotiate
TLS on the fly without having to reconnect. They are flagged as "e" to show
that encryption was dynamically added, as opposed to "E" which indicates an
initial TLS connection.

Certificates are now automatically generated and this allows HTTPS connections
from browsers.  For now this is of limited use, but it will come handy in the
near future when building a web-enabled GUI.

To be more resilient against crashes, gtk-gnutella now automatically launches
a supervisor process that will launch the real gtk-gnutella as a child process
and monitor its fate, restarting a new process when the old one failed.  This
is far more robust than having the process re-exec() itself at crash time since
there are some crashing conditions that do not even allow the process to go
that far in the crash handling...

On Windows, provided you have installed Cygwin's gdb, crash logs will now
contain a gdb backtrace of the failing process, making analysis of what went
wrong easier than with a simple stack trace.

Your previous GUID and KUID will be regenerated the next time you restart due
to a new algorithm used to detect that a configuration file is not accidentally
reused on another machine: the host name is now included, instead of just the
physical file information.  So when moving a disk to another machine, or simply
cloning an existing virtual machine, we are no longer going to reuse these
IDs which are supposed to be unique by properly detecting that the information
was copied over.

A bug in open_read() caused the Geo IP database to not be loaded on Windows.

Finally, all the options given to gtk-gnutella can now be abbreviated as long
as they are not ambiguous (i.e. enough is given to make them non-ambiguous).
For instance, given the current set of options, --p would be ambiguous but --s
will always mean --shell.  However, --pi is not ambiguous and refers to --ping.

Improvements:
- By default, gtk-gnutella now supervises its children to restart them.
- Now allows incoming HTTPS connections.
- Added support for Gnutella connection upgrade to TLS.
- Added support of RFC-2817 for upgrading to TLS within HTTP/1.1.
- Dump symbolic stack when crashing in supervised mode with our parent.
- VMM: added new flag to signal OOM condition and be aggressive with the cache.
- Options can now be abbreviated as long as they are not ambiguous.
- Added support for Virtual Memory Emergency Allocation (VMEA).
- Pulled latest translations from Transifex.

Bug Fixes:
- Make sure node_by_guid() cannot return a G2 node!
- VMM: fixed memory allocation logic during crashes.
- open_read(): fixed logic on Windows when no renaming is requested.
- Make sure we don't restart nor pause a failing process on --shell or --ping.

Under the Hood:
- Added spopen(), a simple popen() bypassing the shell.
- Added Windows-specific PROT_GUARD protection type for mprotect().
- Added log_show_pid() to direct the logging layer to show or hide the PID.
- Added library support for file locks.
- Added compat_process_exists() and compat_kill_zero().
- Added ability to dynamically limit walloc() usage, remapping to xmalloc().
- Added ability to disable halloc() at runtime, remapping it to xmalloc().
- Added specific PID file for locking out the supervisor process.
- Do not install periodic xgc() and zgc() unless running in a long-term process.
- Refactored main() initializations to limit memory usage in the supervisor.
- Windows: stop fatal recursion when the VMM layer extends the pmap.
- Windows: revisited exception logging to give more details and simplify code.
- Windows: reworked stack overflow detection logic.
- Windows: added launch() and spopen() support.
- Windows: added support for wait() and waitpid() on launched processes.
- Windows: launch gdb in a separate thread to get symbols when crashing.
- Windows: re-worked early init code to allow memory allocation.
- Windows: will now be building with gnutls-3.4.5.
- Windows: added getppid() support.
- Windows: added getuid(), geteuid(), getgid() and getegid() emulations.
- Windows: try to have SymInitialize() done as soon as possible.
- Windows: added support for getrusage(RUSAGE_CHILDREN).
- Make sure the logic used to construct fallback path is consistent.
- Refactored Windows socket initialization.
- Refactored setproctitle(), adding getprogname() and setprogname() as well.
- Revisited crash_mode() to include the notion of criticity level.
- Switched rand31() to the Park and Miller algorithm.
- SDBM: added fadvise() hint for page accesses, with a "random" access mode.
- Use short_time_ascii() instead of short_time() in log messages.
- TLS: use our own random number generators.
- TLS: use new types, with the _t trailing prefix.
- TLS: added support for a global audit log, available since gnutls 3.0.
- TLS: added vectorized push routine.
- TLS: added generation of private server key at startup if missing.
- TLS: don't need anonymous server credentials if we have a certificate.
- TLS: added generation of self-signed certificate at startup if missing
- TLS: removed ARCFOUR-40 from the list of overrides for GnuTLS 3.4.5.
- TLS: enhanced to support GnuTLS 3.x and allow HTTPS connections.
- TLS: the "custom I/O" push/pull routines are now the norm.
- TLS: normalized logging to always use G_STRFUNC for non-informative messages.
- SHA1_process_message_block(): make sure SHA1 is correct on big-endian systems.
- cq_init(): always warn if callout queue exists, regardless of its thread.
- cq_init(): loudly warn if the callout queue was created automatically before.
- crash_generate_crashlog(): dump thread locks before current stack.
- crash_init(): now calls stacktrace_init() with immediate symbol loading.
- crash_invoke_inspector(): also attempt to launch gdb on Windows.
- crash_invoke_inspector(): force emission of decorated stacks.
- crash_try_reexec(): do not exec() ourselves when we have a supervising parent.
- download_get_server_name(): when name changes, reset some internal attributes.
- entropy_seed(): make sure we're correctly seeding our KISS RNG.
- file_locate_from_path(): tweaked for Windows to add implicit "." in PATH.
- gtk_gnutella_atexit(): do nothing if we're already crashing.
- gwc_parse_dispatch_lines(): avoid using "eof", it shadows a global on Windows.
- hash_table_replace(): fixed logic when inserting into a fix-sized table.
- kuid_random_fill(): use random_key_bytes() to generate unique KUID.
- mingw_exception(): maintain exception recursive depth per thread.
- mingw_execve(): redesigned to avoid using external resources.
- mingw_fcntl(): added F_RDLCK (read-lock) support for F_SETLK operations.
- mingw_fcntl(): return ENOSYS for unimplemented parts, not EINVAL!
- mingw_signal(): be thread-safe, in case of concurrent updates.
- mingw_sigraise(): trace signal, since it could be the prelude to a crash.
- node_can_accept_connection(): even when "offline", accept nearby hosts.
- node_is_now_connected(): watch out for disconnected nodes after RX injection.
- pncs_convert(): avoid using the stack, prefer a thread-private buffer.
- sdbm_set_volatile(): forgot to grab lock on entry.
- sdbm_thread_datum(): avoid too many re-allocation overhead, sacrificing memory.
- settings_random_save(): now merge randomness instead of just superseding it.
- shell_exec_thread_list(): use configured stack size if available.
- signal_perform_cleanup(): trace signals we get during cleanup.
- spinlock_crash_mode(): dump PID as well in case process forked.
- stack_print_decorated_to(): switch to lighter tracing if we hit an OOM.
- thread_launch(): warn once if pthread_attr_setstacksize() returns an error.
- thread_launch_register(): force new PROT_GUARD protection on red-zone page.
- tls_handshake(): log IP:port and whether remote is client or server.
- tm_init(): now controls whether to start the time thread.
- unique_file_token(): include the hostname into the unique file ID.
- vxml_parser_remove_buffer(): application logic was done only when debugging!

Enjoy!
