# v 1.2.2  2022-02-25  [stable]

This is a maintenance release with major bug fixes.

There were several shortcomings with bandwidth management: capping was not
performed correctly and could overuse uploading bandwidth. Also when the DHT
is turned off or on, we need to recompute proper bandwidth stealing.

Corruption of the DHT disk databases could also lead to a crash.

There was a critical old bug in the Dynamic Querying layer that affected
Ultrapeers mostly: we could corrupt memory and/or crash when the current node
was removed and we were processing a Dynamic Query for that node.  This is
more likely to happen when running as an Ultrapeer but it could also affect
nodes running as leaves, although the probability of that bug happening is
much less in that case.

Finally, it is best to not iterate on a global list that could get changed
due to a node removal.  This was the case when sending pongs to neighbouring
nodes, so we now take a private copy.

Improvements:
- Extended "props" shell command with -e (exact) and -i (ignore missing).
- The "props" command now takes a set of properties, handled as one batch.

Bug Fixes:
- Properly recompute bandwidth stealing on DHT changes.
- Avoid crashing in D-Bus lib when filename is improperly UTF-8 encoded.
- DHT: protect against corrupted database.
- bw_available(): fix invalid logic for I/O source capping.
- pong_all_neighbours_but_one(): iterate on local list.
- dq_node_removed(): must free dq object asynchronously.

Under the Hood:
- Update IRC network information: moved from freenode to libera.chat
- Chunk size limiting for uploads accounts for bandwidth.
- Reduce memory footprint for statx_t if no data kept.
- CQ: defer freeing of dispatched event.
- watchdog: be more verbose within critical messages.
- node_parse(): signal to callers when we have BYE-ed the node.
- cq_event_called(): use better diagnostic on assert failure.
- dbus_util_send_message(): protect against invalid text.
- prepare_entry(): ensure entry invariant remains true.
- wd_expire(): do nothing if watchdog was asleep.

# v 1.2.1  2021-07-12  [stable]

This is a maintenance release with minor bug fixes.

Note that our project IRC #gtk-gnutella channel is now on irc.libera.chat.

When launching gtk-gnutella and there is a stale lockfile present, listing
some PID, and it happens that there is already another process running
under this PID, we abort, complaining that another gtk-gnutella is running.
However, if the lockfile is really stale, and the PID listed in there has
nothing to do with gtk-gnutella at the moment, the user will need to remove
the stale lockfile.  Hence we show them the command to run, listing the
full lockfile path so that it is easy to overcome this little inconvenience!

When using hashtables for memory management, it was possible to trigger a
resizing and, during the course of operations, have further memory used,
requiring tracking of new items in the same hashtable we were in the
process of resizing.  That led to double VMM freeing of the region used
to store the data.

Add properties to track bytes exchanged by schedulers.  These properties
track the amount of bytes exchanged by session and are reset to 0 whenever
a new user session starts.  It allows users to see the actual amount of
data consumed by running gtk-gnutella sessions, programmatically via the
shell interface.

Add -t switch to shell "status" command: this displays the total amount
of bandwidth consumed during the session for the different schedulers.

Improvements:
- Show command to clean stale lockfile.
- Add properties to track bytes exchanged by schedulers.
- Add -t switch to shell "status" command.
- Make use of libera.chat instead of freenode.
- Expiration time now increased from 1 to 2 years.
- New --no-expire switch to disable GUI popup when expired.

# v 1.2.0  2020-07-09  [stable]

This is an evolution release, hence the minor version bump.

Several cases of bad input (from network) causing assertion failures were
fixed.  In particular, bad DHT response after a security token lookup or
invalid G2 input streams were fatal.

There was also a critical bug, originating from a harmful code typo, which
led gtk-gnutella to serve unvailable file chunks from partial files, as if
they were available, resulting in unintended download corruption on the
remote end!

Thanks to Laurent Gil's efforts, it is now possible to run gtk-gnutella from a
Docker container.  See https://github.com/angegar/gtk-gnutella-docker.
Running within docker raised some issues about sbrk() and thread_self(),
which were fixed.

The computation of the build date was fixed, to avoid corner cases where
gtk-gnutella would complain it was "old" when freshely compiled from
up-to-date sources in a git tree whose "master" branch was only \ 
infrequently
updated.

The file selector was fixed, to avoid displaying grayed-out folders, a setup
wich did not allow one to actually select directories in the preferences.

Many improvements were done to allow smoother uploading for servents with
more bandwidth than the recipients.  Instead of drastically limiting upload
bandwidth (which was negatively impacting everyone), we are now monitoring
and adjusting our uploading speed to avoid congestion on the remote end.
When stalling happens, we also react quickly to reduce the available bandwidth
of the connection, not that of all connections to whom we are uploading.

We also no longer rely on MaxMind GeoIP for providing the IP -> country
mappings.  Their distribution mode now requires a specific licence which seems
totally incompatible with the gtk-gnutella's distribution mode.  Instead, we
are now using IP2Location, and the GEO_LICENCE file now lists the conditions
under which these data are re-distributed (gtk-gnutella transforms the data
into a form that it can digest, so we are distributing a modified, derived
work, not the original).

If you are still using a version of gtk-gnutella earlier than the 1.1.x
series, you are strongly encouraged to upgrade.  Starting from this release,
we are now considering these versions too old to connect to.

Improvements:
- Let --compile-info show which malloc() is used.
- It is now possible to run gtk-gnutella from a Docker container.
- Added details in the README file about required packages to compile.
- Use gradual bandwidth penalty when uploads are stalling.

- Upload tab now shows our own partial completion ratio, not just \ 
"(partial)".
- Detect abuse from HTTP clients not reading payloads.
- Enforce Retry-After softly.
- Ban them when they abuse of the browse-host feature.
- Smarter detection of duplicate incoming Gnutella connections.

# v 1.1.15  2019-07-14  [stable]

This release is a maintenance one fixing several minor bugs and two annoying
ones:

- The semi-reliable UDP layer could crash due to an assertion that started
  to trigger with the introduction of an explicit flush before the message
  times out for transmission.

- Due to an overseen condition, we were not able to serve seeded files when
  Partial File Sharing is enabled.  A seeded file is a completed file that
  still lies in the downloaded directory but is not part of the library
  directories.

The OOB banning code for hosts that never claim their OOB hits was also
revisited to prevent problems with hosts that query a popular file and then
get submerged by hits and thus refrain to claim the additional hits.  We are
now much more tolerant to avoid accidentally banning innocent hosts.

On Windows, the disassembling of machine instructions was enhanced to further
improve the ability to correctly issue symbolic stack traces when encountering
assertion failures or during crashes.

Finally, the Geo IP databases were refreshed.

Improvements:
- OOB: increased timeout for OOB hit delivery.
- OOB: switch to unreliable notification if semi-reliable UDP fails.
- OOB: raise the bar for banning after unclaimed OOB hits.
- Dynamic Hits: let us forward hits that bear a small amount of results.
- Count amount of banning we have to do for OOB querying hosts.

Bug Fixes:
- Rename statx struct to statistics to avoid name collision.
- browse_host_read_html(): fixed English typo.

# v 1.1.14  2018-10-04  [stable]

This release mostly improves the core routines and fixes a few important bugs.

Due to a bug in the usage of the RX buffers, we were not correctly parsing
data returned in "chunked" transfer-encoding by HTTP/1.1 servers.  This
affected the UPnP logic.

The UPnP port unmapping done when the program shuts down was also not being
able to complete successfully because we were preventing the HTTP connection
from going on during the shutdown.  Not critical because there is a lifetime
attached to all mappings, but always best to properly clean-up when leaving.

The algorithm used to pick random chunks to download was also revisited to
ensure a uniform selection within the whole file ranges that remain to be
fetched.

At startup time, the DHT code no longer expires keys when reloading data.
This could create crashes during the operation, with no other remedy than
to erase all the DHT database files manually to be able to recover!

The background task layer was also causing crashes (at exit time though)
because it was not recording whether it was running "user" code as opposed
to "kernel" code.

The SDBM code was also improved to allow concurrency and, in particular,
a "loose" iteration scheme which does not need to grab the database lock
during the whole iteration process.  It is also possible to perform a
concurrent database rebuilding.

The thread runtime now has an improved deadlock detection engine, based
on a topological sort, that can definitely tell whether we are deadlocked.
When the deadlock is detected, we can also have more information about
the threads participating in that deadlock condition, to assist debugging.

On Windows, a bug in our mingw_dlerror() emulation caused it to always
fail once an error had been recorded, leading to un-decorated subsequent
stack traces, which really do not help on that platform!

There was also a concurrency bug in the processing of network queries.
Every time the library was rescanned, it could trigger a crash due to
a memory zone being declared private and was in fact shared between
threads.  The crash occurred only when a query was received on the
Gnutella network whilst the library was rescanned.

The semi-reliable UDP layer TX side was revisited to maximize chances that
reliable messages get through completely.

The pattern matching code was revisited thoroughly.  A new algorithm (2-Way
String Matching) now complements the Quick Search algorithm and an initial
benchmarking is done to compare our own matching routines with native libc
versions of strstr(), strlen(), strchr() and memchr().  The fastest routine
is then selected, to ensure optimal performances.  There is also a unit-test
program ensuring proper semantics for the pattern search flags.

- [GTK2] Catch column resize events to persist widths quickly.

# v 1.1.13  2017-10-22  [stable]

This release primarily addresses issues that were left-over in 1.1.12.
Do not use that previous release, migrate from 1.1.11 to 1.1.13 directly!

The main issue was that of Partial File Sharing.  Numerous bugs, dating from
7 years or more, were lurking because my local configuration had switched PFS
off for testing, and it had never been turned back on!  In particular,
completed files were not properly shared, it was not possible to upload their
THEX since it was not recomputed, and the files were not properly indexed in
the Query Routing Table due to bugs in the background task layer.

In case of a crash, we now dump the value of all the Gnutella properties to
be able to spot configurations that deviate from the norm.  Too many bugs
were reported and ignored because they could not be reproduced, often due
to not having the same setup when attempting to debug!

Another nasty bug was fixed: it was not possible to change the IP support
configuration without causing an immediate crash.  The reason is due to a
change that was integrated in 1.1.12 to allow IPv6 UDP traffic from G2 nodes.
The problem was that this created an extra client stack on top of the
low-level UDP traffic scheduler and it was not properly cleaned-up when
switching IP configurations, leading to an assertion failure!

New Features:

Improvements:
- Append all Gnutella properties to the crashlog file.
- At startup, do not needlessly request TTH if we have it cached already.
- Optimized requests for library scan / QRP rebuild, avoiding multiple events.
- Allow TTH computation for seeded files.
- Obsolete and stale entries are now removed from the SHA1 cache.
- [GTK] Added GUI events on more fileinfo changes.
- [GTK] Show information about recomputed TTH for seeded files.
- Prune unshared entries from SHA1 cache at startup.
- Persist information about seeded files in the ASCII fileinfo database.
- Remove unneeded libraries from the default GTK2 ldflags.

Bug Fixes:
- Was not able to properly seed completed files; fixed shared_file_path().
- Was not always updating QRP on the UP side after a library change.
- Could have background tasks stuck after cancelling a multi-ref'ed one.
- Dynamic querying timeout was not properly computed (made too small).
- Changing from "IPv6 & IPv4" to "IPv4 only" mode caused \ 
a crash.
- Restored ability for "shutdown -r" to work.

Under the Hood:
- Added prop_to_typed_string().
- Added s_where() to log a stacktrace on stderr only.
- Added tt_slice_size() to compute slice length per leaf in the TTH.
- New crash_dumper_add() to register crash dumper callbacks.
- No panicing when thread cannot block but was actually suspended.
- Was unduly offsetting stacktrace by one extra level.
- bg_sched_sleep(): don't reduce runcount on exiting task!
- bg_sched_timer(): added run count consistency check.
- bg_sched_timer(): fixed logging of task's run time.
- bg_task_cancel(): log task address as well, not just the task name.
- bg_task_wakeup(): must clear user sleeping flag.
- crash_restart_notify(): use smarter crash_exit().
- crash_try_reexec(): suspend other threads as a precaution.
- deflate_flushed(): suppressed soft assertion.
- dq_results_expired(): fixed improper timeout computation.
- fi_free(): cut any pending reference by uploads!
- fi_tigertree_check(): more verbose in case of errors.
- file_info_moved(): must update fi->modified as well.
- file_info_remove_source(): removed unused discard parameter.
- file_info_retrieve(): also validate that DONE is consistent.
- file_info_shared_sha1(): do not share bad files.
- get_file_to_upload_from_urn(): factorized code.
- huge_update_hashes(): enforce one sync of SHA1 cache every minute.
- huge_verify_callback(): use shared_file_indexed().
- node_udp_disable(): was not disabling the G2 UDP IPv6 node.
- parse_and_append_cache_entry(): discard obsolete / stale entries.
- qrt_compressed(): fixed outdated comments.
- qrt_diff_1(): was never considering change.
- request_sha1(): don't request TTH if we have it cached.
- shared_file_fileinfo_unref(): clear fileinfo pointer.
- shared_file_from_fileinfo(): copy TTH atom as well, if any.
- shared_file_is_shareable(): be stricter for partial files.
- shared_file_path(): must process sf->fi correctly!
- upload_file_present(): loudly warn when completed file changed on disk.
- upload_file_present(): loudly warn when file not shareable.
- verify_update(): loudly warn when "progress" callback stops processing.

# v 1.1.12  2017-09-20  [stable]

This release fixes a very critical bug that was only manifesting when Partial
File Sharing was turned on, and which caused possible memory corruption (leading
to a sure crash later) when enqueuing new files for downloading.

New Features:
- Throttle browsing requests to one per hour from a given IP.
- Limit uploads to stalling hosts to 1, regardless of user settings.
- [GTK2] Show proper average data speed on completed uploads.

Improvements:
- Added "WSHR" vendor code for WireShare.
- Added "ENVY" vendor code for Envy.
- Do not attempt costly operations after a crash / auto-restart.
- Updated FAQ  -Uploads and Sharing-
- Use 64-bit variables for bandwidth computations.
- Make sure early stalling is not always reported for the same IP.
- Use even HTTP outgoing bandwidth as the last measure when stalling.

Bug Fixes:
- Allow IPv6 UDP traffic from G2 nodes.
- Be sure to use destructive list iteration with tmalloc_free_magazine().
- Critical upload HTTP statuses are now fully sent.
- Must give plain (untranslated) strings to send_upload_error().
- bg_task_finished(): now calls safer bg_task_dead().
- file_object_open_from(): also catch EROFS when opening file.
- node_bye_v(): do not call node_remove_v() for G2 nodes.
- vendor_code_get_name(): fixed validation of unknown code tokens.
- verify_next_file(): fixed wrong argument order in log message.

Under the Hood:
- bfd_util: reworked mutex grabbing in an attempt to avoid deadlocks.
- binary_hash(): disperse bits in initial hash value.
- check_for_events(): optimize path if timeout is 0 or we collect events.
- cq_event_called(): only zero variable holding event when asked!
- cq_zero(): now always nullify the event, as the name suggests.
- crash_setmain(): avoid spurious warnings with recent gcc.
- english_strerror() and symbolic_errno() made thread-safe.
- inputevt_timer(): factorized common code into new inputevt_handle().
- socket_udp_flush_queue(): do not process anything if we cannot devote time.
- stack_sym_trylock(): avoid deadly recursions through stack lock dumping!
- thread_sig_handle(): use atomic exchange operation to clear pending set.
- u32_ptr_hash(): discard lower bits of the multiplication as well.
- upload_timer(): clear the stall flag when it is over.
- Added aging_record() to simplify code for plain keys.
- Added cq_event() to acknowledge reception of events we do not track.
- Added "inputevt_trace" property for tracing dispatched I/O callbacks.
- Added english_strerror() to guarantee English messages.
- Added thread_signal_has_pending() and thread_signal_process().
- Added "lock_sleep_trace" and "lock_contention_trace" \ 
properties.
- AJE: changed pool #0 filling policy and reseeding checks.
- Ensure misc_init() is called before using lookup tables.
- Simplify is_ascii_*() by performing table lookup.
- Thread runtime now allows a signal handler to run within another one.
- Updated UHC list, fixed obsolete port numbers.
- Use new cq_event() in thread callout events to avoid possible leaks.
- Watchdog: revisited logic to do more under lock protection.
