* chore: allow vararg calls in qt/.clang-tidy
An awkward PR since this isn't intended for the qt/ codebase at all, but
rather for use with libtransmission instead. But libtransmission is *so*
noncompilant at this point that this config can't be promoted higher up
the tree yet. Instead, it needs to be callable on-request by devs.

of using dynamic allocation, use a fixed-size array that's big enough to
fit the strings that we have.

* 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

[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.

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.

* feat: add torrent-get 'primary-mime-type' to RPC.

torrent. This info can be used to display the torrent, e.g. by using an
icon that corresponds to the mime type.

* 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.

Previously it was calculated from `log10(1.0 / DBL_EPISILON) - 1`;
however, there's no need to calculate it out when there's an ANSI
standard that already spells it out consisely.
In libtransmission/variant.c, function tr_variantWalk, when the variant
stack is reallocated, a pointer to the previously allocated memory
region is kept. This address is later accessed (heap use-after-free)
while walking back down the stack, causing the application to crash.
The application can be any application which uses libtransmission, such
as transmission-daemon, transmission-gtk, transmission-show, etc.

* feat: add tr_stat.infoDate to note tr_info changes
The last time during this session that any tr_info field changed
(e.g. trackers/filenames edited or magnet torrent got metadata).

don't usually change.

* refactor: remove redundant speed stats collection
* refactor: remove unnecessary tor->isQueued() calls
* refactor: use unordered containers where possible
* scale favicons only once, when adding to the cache
* feat: add optional "format" arg to torrent-get RPC
If the "format" request was "objects" (default), "torrents" will be an
array of objects, each of which contains the key/value pairs matching
the request's "fields" arg. This is unchanged from previous versions.
If the format was "table", then "torrents" will be an array of arrays.
The first row holds the keys and each remaining row holds a torrent's
values for those keys. This format is more efficient in terms of JSON
generation and JSON parsing.

* Fix -Wcast-function-type warnings in GTK+ app code
https://gitlab.gnome.org/GNOME/gnome-terminal/issues/96 talks about both
the issue and its solution.
GCC 8's -Wcast-function-type, enabled by -Wextra, is problematic in glib
applications because it's idiomatic there to recast function signatures,
e.g. `g_slist_free(list, (GFunc)g_free, NULL);`.
Disabling the warning with pragmas causes "unrecognized pragma" warnings
on clang and older versions of gcc, and disabling the warning could miss
actual bugs. GCC defines `void (*)(void)` as a special case that matches
anything so we can silence warnings by double-casting through GCallback.
In the previous example, the warning is silenced by changing the code to
read `g_slist_free(list, (GFunc)(GCallback)g_free, NULL);`).

In some filesystems, including ones mounted on a network drive, using a small buffer size
significantly hurts copy performance. Upping the buffer to 1024kb to increase copy performance.
* Unify/Modernize TOS to DSCP standards
The set of pre-named TOS values are now renamed to the latest DSCP
standards, with traffic classes and everything exciting. To keep
everything in the same place, a segment has been added to net.h to keep
the currently named values.
A result of these changes is that "lowcost" is probably no longer
harmless, as it now encourages the router to preferentially drop the
packages when bandwidth requires so. "lowdelay" is assigned to a pretty
high AF class for SIP and stuff. I am not sure at all about the
"throughput" assignment. I mean, the whole point of DSCP-fication is
translating from the old ToS bits to a more precedence-based notation,
and precedence is supposed to lie beside the old 4 ToS bits...
A funny interaction between the AFxy and the old ToS fields lies in
the old "reliability" (0x08) field. All odd numbers of y (1, 3 : low,
high) switches it on. If you spend 5 more minutes on it you can probably
come up with "pun" values that hold similar meanings in DSCP and
Prec/ToS.
By removing the IPv6 override, I should have kind of satisfied the #692
request.

Apply the same rules on all the supported platforms to avoid issues

Fixes: #294
RFC 2616 defines headers as case-insensitive, so if rpc is behind a
reverse proxy that lowers the case of headers, transmission will not
parse them correctly.
A new wrapper function, `tr_strcasestr` is added to
libtransmission/utils.c to allow for comparisons of headers case
insensitively, and checks in cmake and autogen are included.

I'm seeing 7 potentially false reported issues re. use of uninitialized buffer
data here. It seems that `read` function should be properly supported by
Coverity, but maybe it can't figure out the postconditions of it properly...
Walking in the dark here.
Remove static assert altogether: it should have worked everywhere anyway,
otherwise there is no point.
Add a few casts here and there to ensure proper type for directory handle.
* Silence coverity CHECKED_RETURN on added.f load
The existing code behaved alright since added.f is optional.
However, by testing for success we can both silence the warning
and prevent a useless initialization of NULL/0 to added_f and
added_f_length.
* Silence coverity CHECKED_RETURN on added6.f load
ipv6 variant of previous commit.
* Silence coverity CHECKED_RETURN writing benc strs
saveStringFunc() gets the target string by calling tr_variantGetStr().
It previously didn't check to see if this function succeeded because
saveStringFunc() isn't reached without the type already being known.
However, checking the return value costs nothing and makes Coverity happy.
* Silence coverity CHECKED_RETURN on ut metadata
Like earlier few Coverity commits in this PR, we're handling optional
values by declaring stack locals set to the default (e.g. -1) and then
trying to read the variant.
Unlike the earlier commits, there is a two-part step to thise read:
checking for the metadata, then checking for the individual fields.
The earlier fixes' aproach -- e.g. initializing to -1 only if the reads
failed -- would involve new nested conditionals. I find the new complexity
to outweigh the benefit of removing the dead store, so in this case I'm
casting the return value to `(void)` to tell Coverity to shush.
* Silence coverity CHECKED_RETURN on scrape
Check the return value of tr_variantGetInt() when showing
seeder and leecher counts in transmission-show.
* Silence CHECKED_RETURN on rpc recently-active
When building a list of removed torrent IDs from variants, confirm that
we can read the IDs from the variants before adding them to the list.
I don't _think_ this would have failed before, but Coverity's right that
it's reasonable to add a safeguard here.
* fix: better fix to serializing benc strings
The approach in 33e2ece7e5 was
a little problematic: GetString() shouldn't fail here; but if

* don't lookup a value we already have
* make an array for known too-big scrape error messages
* improved multiscrape throttle logging
* fix: multiscraping of low numbers of torrents
Handle the case of getting a 'multiscrape too big' error message
back even if the user fewer than TR_MULTISCRAPE_MAX torrents.
* uncrustify
* fix oops
* refactor: remove TR_MULTISCRAPE_MIN
Is there any reason to have a minimum batch size?

This is useful if the client script is going to access
the .resume file. Ensuring an up-to-date .resume file
means that user scripts will be able to access it.
This commit adds a new blocklist line format, namely individual IPv4
CIDR ranges separated by newlines. Text put after each entry is ignored
by sscanf, so feel free to put any kind of comments there.
Fix#230.
Set the first version component to be the same as the last Subversion-based
release build version and add two more components (major and minor version
numbers). To allow for nightly build updates this should probably include
another component (e.g. build timestamp), but we're not there yet.
This seems to be the idiomatic way to fix libressl compatibility issues,
judging by what most other open source projects seem to be doing.
I've confirmed that transmission builds with libressl for me after this
patch is applied.
While zlib is mandatory for transmission, it is not mandatory for curl.
A libcurl that has been compiled with no support for zlib will return no data if compressed responses are set to on.
In the basic case this prevents the port checking functionality from working properly. It also prevents web seeding from working as well.
While resolved paths always contain the `\\?\` prefix, it's not always
correct to strip only those 4 chars. In case of UNC paths, the prefix
is actually a bit longer (`\\?\UNC\`) and needs to be replaced with `\\`
instead.
Failing to do so results in invalid paths, e.g. `\\Host\Share\File` becomes
`UNC\Host\Share\File` which totally wrong.

Store full revision hash in REVISION file. Write fixes 10 chars of revision
hash to version.h. Use `#pragma once` in version.h. Support getting revision
from TeamCity environment variable (similar to Jenkins).
Walk up one level at a time until the directory creation succeeds, then go
back down one level at a time. This reduces the number of operations in the
most common case (when directory already exists).
The format introduced in TRAC-394 is nice but brings its own issues (e.g.
TRAC-4189, #122). I'm okay with a bit of grepping myself if it makes the
experience better for end users.
Using hashes results in filenames well under 255 bytes limit on some
filesystems. If even that will not be enough, I'd suggest reporting the
issue elsewhere.
Fixes: #122
Since one cannot really compare system time to filesystem time (see e.g.
https://lkml.org/lkml/2017/3/30/809), allow for 1 second error to avoid
(or at least minimize) random test failures.
