* Switch to a standalone ARC4 implementation
This frees us from expecting it being provided by one of the crypto
libraries we support, all of which deprecated and/or removed it at this
point.
Fixes: #1103Fixes: #1777
* Suppress lgtm warnings about RC4 being weak (we don't care)
The previous code had some redundant calculations, e.g. calling
tr_torrentGetActivity() a couple of times per torrent, once in
tr_sessionCountQueueFreeSlots() and once in tr_torrentIsStalled().
Only one call is necessary.
tr_sessionCountQueueFreeSlots() used to keep iterating through all
torrents even if the number of free slots had already been decremented
to zero, even though further iteration does not change the zero return
value :) This PR checks the return value while looping to prevent this.
* perf: if logs are disabled, don't build log names
handshake.c and peer-io.c call tr_peerIoGetAddrStr() to build a name for
passing to tr_logAddDeepNamed(). Since tr_peerIoGetAddrStr() isn't free,
make sure deep logging is enabled before building the name.
* perf: prioritize announces based on scrape stats
This change is to improve responsiveness when starting a large batch of
torrents, e.g. when starting up a seedbox, but is also generally useful.
First, try to scrape as many torrents as as quickly as possible, giving
preference to that even over announces. Thanks to multiscrape we can run
through scrapes an order of magnitude faster than announces. Then scrape
responses tell us which swarms have leechers and we can prioritize those
torrents' announces.
Second, increase how many scrapes and announces we start at a time. This
limit probably hasn't been needed since 2da97b25 and by scraping faster,
the sooner we'll know which torrents to announce first.
* chore: remove printf() tracer
* perf: use scrape to know when a swarm is all-seeds
For private torrents, the tracker is the sole source of peers. So when a
private torrent's tracker responds that there are 0 leechers, we can use
that information to mark the entire swarm as seeders and to not initiate
connections to those peers if we are seeding. This can help seedboxes to
more efficiently pick which swarms to prioritize.
This strategy is not used on public torrents, since new seeder-to-seeder
connections can be useful there for pex.
This PR changes tr_peerMgrAddPex() to (1) remove tr_atom.seedProbability
field (which was not as robust as intended) and (2) add batches of peers
instead of a single peer.
* fix: only use all-seeds check for private torrents
tr_peerMgrStartTorrent() is called once per torrent on startup, so this
can be expensive if the user has a lot of torrents.
Instead, enqueue a pending rechoke that will happen on idle. This way,
all the added torrents can be handled by a single rechoke call.
* perf: lookup tables for faster torrent searching.
tr_torrentFindFromId(), tr_torrentFindFromHashString(), and
tr_torrentFindFromHash() are now O(log N) instead of O(N) where
N is the number of torrents.
* build: fix clang-tidy warning
error: integer to pointer cast pessimizes optimization opportunities
[performance-no-int-to-ptr,-warnings-as-errors] from TR_BAD_SYS_FILE
which expands to INVALID_HANDLE_VALUE ((HANDLE)(LONG_PTR)-1)
* Add in-kernel copying support for Linux (sendfile64(2), copy_file_range(2)), FreeBSD 13 (copy_file_range(2)), MacOS (copyfile(2)), and Windows (CopyFileExA).
* Fix macro name USE_COPY_FILE_RANGE.
* Minor bugfixes for userspace fallback.
* Fix linux sendfile64 bugs.
* Remove some overzealous asserts.
* Allow transmission-test-copy to take an optional argument for an external reference file.
* Fix return value error of tr_sys_path_copy.
* Use COPYFILE_ALL for Macs without COPYFILE_CLONE.
* Add in-kernel file copying for several platforms.
Numerous operating systems now have support for copying files directly in the
kernel, which is generally more efficient than copying in a userspace read(2)/
write(2) loop. (This becomes particularly relevant for 4th gen PCI-E storage,
which approaches the latency of DRAM.) For Linux I use sendfile64(2), and, for
later kernels, copy_file_range(2). FreeBSD 13 will also support
copy_file_range(2). MacOS has copyfile(2), and Windows has CopyFileExA.
Operating systems lacking such a syscall continue to use the existing
read(2)/write(2) loop.
* Appease uncrustify.
* Appease uncrustify.
* copy-test: generate random content at run time.
* copy-test: Stylistic changes and more check()s.
* copy-test: files_are_identical should follow test idioms
* tr_sys_path_copy: numerous tweaks as requested by review.
* s/old file/source file; s/new file/destination file.
* tr_sys_path_copy: handle win32 wide characters in paths.
* Uncrustify.
* test-copy: Use non-string create_file_with_contents.
* tr_sys_path_copy: numerous fixes.
Per review: generate test file content at runtime; tidy use of check();
fix style; re-measure file sizes in the copy; define a macro when the
system does not provide it; use Unicode APIs on Windows; and fix
documentation.
* Updated as per comments.
* Rebase kernel-copy changes onto 3.0 with gtest.
* Undo irrelevant comment change.
* Fix syntax error.
* Use tr_malloc() instead of tr_valloc().
* Use EXPECT instead of TR_ASSERT in gtest.
* Add error handling.
* Acceptable coding style has changed again.
Now it's camelCase. Also use nullptr instead of NULL, etc.
* Fix east/west const.

This is based off of PR#1526 by azy5030 to add in: Torrent Web, BiglyBT, and FrostWire. I made the additional change requested by livings124.
In addition this also adds support for: HTTP Seed, aria2 (#532), and BitLord.
* refactor: remove unnecessary func tr_valloc()
We're only using it in a handful of places, and none of them need the
kind of alignment that posix_memalign() provide. So we can drop a few
dozen lines by removing the portability wrapper.
* refactor: const correctness
* refactor: fix some implicit conversions
* refactor: make local pointers const if their objects are not modified
* refactor: do not cast away const in torrent-cell-renderer
* refactor: remove call to deprecated gtk_icon_size_lookup_for_settings
* refactor: member functions that do not mutate their objects should be declared const
* chore: do not end comments with a semicolon
* refactor: const correctness
* refactor: use getpwuid_r instead of getpwuid
* chore: simplify dict walking loop logic
* refactor: remove dead store assignment in announcer
* refactor: use std::make_shared
* chore: add '@license' tag to web sources' comments
Webpack's tersify plugin looks for that JSDoc tag in order to decide
which comments to extract into the generated license file.
* chore: address sonarcloud.io warnings
* chore: address sonarcloud.io code smells
* fixup! chore: address sonarcloud.io warnings
Give the web client a major overhaul.
User-visible highlights include:
* Mobile is now fully supported.
* Added fullscreen support on mobile.
* Better support for dark mode.
* Added mime icons to the torrent list.
* Improved theme consistency across the app.
Maintainer highlights include:
* Updated code to use ES6 APIs.
* No longer uses jQuery UI.
* No longer uses jQuery.
* Use Webpack to bundle the Javascript, CSS, and assets together -- the entire bundle size is now 68K gzipped.
* Added eslint / prettier / stylelint tooling.
* Uses torrent-get's 'table' mode for more efficient RPC calls.
* feat: add torrent-get 'primary-mime-type' to RPC.
This is a cheap way for RPC clients to know what type of content is in a
torrent. This info can be used to display the torrent, e.g. by using an
icon that corresponds to the mime type.

Remove autotools-based build system (#1465)
* Support .git files (e.g. for worktrees, submodules)
* Fix symlinks in source tarball, switch to TXZ, adjust non-release name
* Remove autotools stuff

* Support .git files (e.g. for worktrees, submodules)
* Fix symlinks in source tarball, switch to TXZ, adjust non-release name
* Remove autotools stuff
Since there is no way to mark parameters as [potentially] unused in
standard C and when using MSVC compiler, use the widely accepted
cast-to-void approach instead.
* Switch to new libcurl's polling interface
* Drop unused includes
* Use NOFILE limit value defined by operating system
* Avoid tight loops, ensure blocking for a small timeout
When there are no file descriptors to wait for, select() would work the
same as sleep(). But curl_multi_wait() returns immediately in this case,
so we need to add explicit wait to avoid tight loops.
Documentation: https://curl.haxx.se/libcurl/c/curl_multi_timeout.html
Discussion: https://curl.haxx.se/mail/lib-2018-03/0074.html
* Bump libcurl minimum version to 7.28.0
* refactor: make variant_headers reusable to qt app.
Torrent.cc's `change()` template methods are generically useful to deal
with tr_variant wrangling, but previously were only used in Torrent.cc.
This PR moves them into a new API `VariantHelpers.h` for use by Prefs,
Session, TorrentModel, etc.
