* 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

* refactor: make torrents' mime icons lazy-loaded.
Another "small wins" patch, this time on CPU: icon loading is expensive,
so calculating them for every torrent all at once on startup isn't the
smartest way to do it.
* refactor: use a vector for FavIcon cache keys
Third of three PRs focused on small memory wins in transmission-qt.
This one saves 1-2 M off RES in my 15K torrent testbed. Not a major
improvement, but nice enough.
Previously we held the torrent's tracker keys in an unordered_set.
That container type is overkill for this field: the list is usually
short and almost never changes, so we don't need fast insertion time.
We can keep the same log N lookup by using a sorted vector and avoid
the excess container size & memory allocations of an unordered_set.
* refactor: intern repeated strings e.g. downloadDir
Add an app-wide interned QString cache for commonly-repeated
strings. Currently used for download_dir, announce_url, comment,
creator, error_string.
* refactor: keep torrent hash in std::array<char,20>
This replaces the hashString QString allocation with a compile-time
array that's included in sizeof the Torrent struct that owns it.
* 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.
* refactor: Torrent::update() returns a delta bitset
Setting up for followup PRs where, instead of doing expensive work every
time there is a change, we can be more fine-grained and do the work only
if the relevant Torrent properties changed.
* chore: make uncrustify happy
* chore: fix #includes
edit-date got added to the backend in 3.00, but I never finished adding
it properly to the Qt client. This PR rectifies that. When a torrent is
edited, the Application and DetailsDialogs will re-query the backend to
update the torrent properties that are needed.
* refactor: use snake_case field naming in qt client
* fix: some missed symbols
* chore: make uncrustify happy
* fixup! refactor: use snake_case field naming in qt client
* chore: remove qvariants from torrent class
* chore: remove unused Q_DECLARE macro calls
* refactor: remove unused includes from Torrent.h
* chore: make clang-tidy and linter happy
* refactor: rename 'setValue()' to 'change()'
* refactor: make tr_variant function paramters const
* chore: remove devel scaffolding
* refactor: rename peer_limit_ to peerLimit_
* refactor: do not use bitwise logic on booleans
* Add EDIT_DATE torrent property declaration (Qt client)
Switch to static assertion to help avoid similar issues in the future.
* Only declare std::hash<QString> for Qt < 5.14
* Pass main window as context when connecting lambdas to torrents model signals (Qt client)
This helps to automatically disconnect from signals on main window
destruction. If not done, use after free is possible since main window is
destroyed before torrents model.
Fixes: #1106
* 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).
RPC clients can monitor this to know when to reload fields which
don't usually change.
* faster updating of trackers combobox.
* generate trackerDisplayNames just once per torrent
* refactor: cache torrent delegate's warning emblem
* refactor: change mainwin refresh debounce to 200ms
* refactor: do not store trackers, hosts in QVariant
* refactor: don't use `virtual` when it's not needed
* refactor: faster counting torrents-matching-filter
* refactor: faster tracker handling in filterbar
* refactor: improve json parser's prealloc heuristic
* refactor: make Torrent::hasError() faster
* 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.
refractor: simplify torrent model signal emissions
The Torrent->Application signal connections make up for about 5% of the
app's memory use. Move this to the TorrentModel so that there are only a
handful of signal connections.
Moving signals to TorrentModel means batch change signals can be emitted
instead of per-change-per-torrent emissions and can be handled that way.
* refactor: keep torrent's time properties as time_t
Comparing QDateTimes is expensive. Keep the torrents' time properties in
the time_t form that we got them from RPG in; difftime() is cheaper.
* refactor: don't load the same stock more than once
Some actions share an icon -- for example, "start all", "start now", and
"start" each use "media-playback-start". When this happens, get the icon
once and cache it to avoid hitting the disk more often than necessary.
In addition, the statusbar's network transfer icon was being reloaded in
a periodic upkeep timer, reloading with QIcon::fromTheme each time. Only
give icons are needed, so load them once and cache them.
* refactor: better lookup of torrent mime-type icons
filename-to-mime-type and mime-type-to-icon lookups are both expensive,
so do a better job of detecting top-level folders and caching the icons
based on file suffixes.
This also lets find a good mime icon even if the torrent doesn't have
its 'files' property populated yet from RPC.
This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped
together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading
types right-to-left, e.g. "constant pointer to constant T" vs. "constant
pointer to T which is constant".
There're places where manual intervention is still required as uncrustify
is not ideal (unfortunately), but at least one may rely on it to do the
right thing most of the time (e.g. when sending in a patch).
The style itself is quite different from what we had before but making it
uniform across all the codebase is the key. I also hope that it'll make the
code more readable (YMMV) and less sensitive to further changes.
Split FileTree.{h,cc} and FilterBar.{h,cc} files so that each class
is in its own file.
This breaks translations (some classes got renamed => context changed),
to be fixed by next commit (along with Tx sync).
