__is_channel_extraction keyed on id == channel_id. That holds for a channel
tab - /channel/UC..., and the videos, streams, shorts and playlists tabs of a
/@handle URL - but not for a channel addressed on its own: yt-dlp reports the
id in the form the channel was asked for, so a bare handle URL yields '@handle'
and a legacy /c/ URL yields the vanity name.
Neither matched, so both fell through to OUTPUT_TEMPLATE_PLAYLIST and the
folder came out as the feed's title. That is why e2c7778 fixed the reporter's
tab URLs while a bare channel URL - what you get copying the address bar - went
on ignoring OUTPUT_TEMPLATE.
Both forms match uploader_id, which is the handle either way, so compare
against that as well, without case: a legacy vanity name and the handle it
became need not agree on it. A real playlist carries its owner's channel_id and
uploader_id but keeps an id of its own, so it still reads as a playlist; no
playlist id can collide with a handle, since those are 'PL...', 'OLAK...' and
the like.
Verified against the live extractor for all six channel URL forms and a real
playlist.

MeTube never sets ignoreerrors, so yt-dlp's trouble() raises DownloadError
instead of returning nonzero for failures like "No video formats found!".
That is the path issue #1047 reports, and it dropped the warnings that
explain the failure because only the nonzero-return branch attached them.
The exception branch now reports the retained warnings with the exception
text as the final line, so the actual error stays prominent under the
context. yt-dlp labels errors "ERROR:" but hands warnings to the logger
unlabelled, so a last warning that repeats the error text is skipped.
Retention is bounded to the last five distinct warnings: fragmented and
live downloads emit a warning per fragment, and the joined message is
persisted with the completed queue and broadcast to every client.

Sites that put a description in the title produce output names past what
the filesystem accepts, and the download fails outright with
"[Errno 36] File name too long". The name is now shortened to fit inside
prepare_filename, which every output path already passes through, so the
main file, its chapter files, thumbnails and subtitles stay consistent.
The limit is read from the filesystem (PC_NAME_MAX, falling back to 255)
and counted in bytes, not characters: a title of accented or CJK
characters reaches it in a third of the characters. The extension is
kept, a cut landing inside a multi-byte character does not leave a broken
sequence, and a reserve is held back for the suffixes yt-dlp appends
afterwards -- '.part', '.ytdl', '.f<format_id>', '-Frag<n>' -- since it
is those that pushed the reported name over the limit.
Names that already fit are untouched, so nothing that downloads today
changes name.

A subscription already carries every other download option and applies it to
each video it queues. Clip bounds were the one exception: 4f83174 added them
for one-off downloads and carved subscriptions out, rejecting the fields in the
subscribe route and stripping them in the UI before the request was built. So
the fields sat visible in the shared advanced-options panel while quietly doing
nothing for a subscription.
Carry them like the rest: two fields on SubscriptionInfo, threaded through the
check flow to add_entry. Stored records that predate the fields take the
defaults, since _from_stored filters by field name.
One thing does not carry over. parse_download_options reads a YouTube t=
timestamp from the URL and turns it into a clip start, which is right when you
paste a link to a moment in a video you want. A subscription URL is a channel
or a playlist, so a timestamp left on it says nothing about the videos that
feed will yield, and honouring it would silently truncate every future
download. The subscribe route therefore takes clip bounds only when the caller
sent the fields explicitly; the t= param is still stripped from the stored URL.
Worth knowing when using this: the range is a fixed offset applied to every
video, so it suits feeds with a consistent shape - a standing intro, a fixed
sponsor read - and will cut in the wrong place on a feed without one.

The folder was already persisted on the subscription and already applied to
every download it queued, but it was missing from the small tuple of fields the
update route accepts, so it could be set when the subscription was created and
never afterwards. That is the same gap the subscription name had in #1044.
Add it to the accepted fields and validate it on the way in, following the
validate_* helpers already in this module. The check is deliberately narrow —
it rejects absolute paths and any '..' component, values that could never be
valid — because the authoritative resolution stays where it already lives, in
DownloadQueue at download time, along with the CUSTOM_DIRS / CREATE_CUSTOM_DIRS
rules and the directory creation. Doing it this way reports a bad edit while
the user is looking at the field instead of failing every check from then on,
without a second copy of the path logic drifting out of step with the first.
subscriptions.py cannot import ytdl.py in any case: ytdl imports _entry_id from
it.
An empty folder stays valid and means the base download directory. A change
applies to future downloads only; files already downloaded are not moved.
This covers the API side of the request. The subscriptions table does not show
the folder at all today, so exposing it in the UI is a separate change.

Routine `pnpm upgrade`. Angular 22.0.6 -> 22.1.2 across the runtime packages

The reporter of #1055 reached for ALLOW_PRIVATE_ADDRESSES to make a LAN proxy
work, which switches off the SSRF guard wholesale. The proxy allowance is
automatic; say so where the flag is documented.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Scoping the connect-time allowance to the configured proxy kept the exception
tied to loopback, so a proxy anywhere else internal — the common case of a
socks5 or HTTP proxy on the LAN — was refused with "Refusing to connect to
non-global address". The only workaround was ALLOW_PRIVATE_ADDRESSES, which
switches the whole guard off, a far larger concession than the setup needs.
The allowance was never really about loopback: it is about the operator having
named this host:port as a proxy. Widen it to any address at a configured proxy
endpoint and nothing is given away, because the match is on the configured host
string rather than the resolved address — a hostile media URL that resolves to
the proxy's address under another name gets no allowance, and one that names the
proxy endpoint itself only reaches the proxy. Every other internal destination
stays refused.
Also log each configured proxy endpoint, so the next report of this shape can be
diagnosed from the log rather than from the guard's source.

The SSRF guard classified addresses with ipaddress.is_global, which looks only
at the outer address. An IPv6 form that carries an IPv4 address at a fixed
offset therefore passed a check the bare address would have failed: the NAT64
well-known prefix 64:ff9b::/96 sits in the 2000::/3 global unicast range, so
64:ff9b::a9fe:a9fe was accepted while 169.254.169.254 was refused. The
deprecated IPv4-compatible form ::/96 has the same property. Both the ingress
validator and the connect-time socket guard classified through the same helper,
so both were affected.
Judge every address a verdict has to account for: the outer address plus any
IPv4 it tunnels, allowed only when all of them are global. Unwrapping this way
can only tighten the verdict, which matters for 6to4 and Teredo — Python
already rejects 2002::/16 and 2001::/32 wholesale, and replacing the outer
address with its payload would have turned 2002:0808:0808:: from blocked into
allowed. Reaching an internal service this way additionally requires NAT64
routing on the host network, which the attacker does not control.

The connect-time guard permitted every loopback address so that a locally
configured proxy (proxy: http://127.0.0.1:9050) stayed reachable. But the
connect guard is the only check that media URLs derived from remote metadata
ever face — validate_url sees just the submitted URL — so that blanket
allowance let a remote manifest steer the download subprocess at services
bound to the server's loopback interface, with the response written to the
download directory and served back by the UI.
Permit loopback only at the host:port of a proxy the operator configured,
taken from yt-dlp's proxy option and the *_proxy environment variables.
Nothing is lost: when a proxy is in use yt-dlp hands it the media URL instead
of resolving that URL locally, so the two cases never overlap. Every other
loopback destination now falls under the same is_global policy as the rest.

GitHub matches a closing keyword anywhere in the message, so the previous
"on its own line in the body" rule was invented. Use the parenthesised subject
form instead: "fix: ... (closes#1040)".
Master is the default branch and is released on every push, so a commit body
that says "Closes #N." makes the issue close exactly when the fix ships and
leaves a permanent link from the issue to the commit — instead of a separate
manual close afterwards. Notes that a bare (#123) in the subject is only a
reference, and that auto-closing still needs an explanatory comment on the
issue.
yt-dlp emits the feed-level .info.json, description and thumbnail from
__process_playlist_result without consulting `download`, so they fell out of
MeTube's classification pass with nothing steering them: they landed in
DOWNLOAD_DIR under yt-dlp's own pl_* names, ignoring OUTPUT_TEMPLATE, the
download's folder and AUDIO_DOWNLOAD_DIR. #1040 reported the names; #660 asked
for control over them. Same accident from both sides.
The classification pass now writes nothing at all, and the files are produced
once the feed has been accepted and its type is known, reusing the template its
items use — OUTPUT_TEMPLATE_CHANNEL for a channel, OUTPUT_TEMPLATE_PLAYLIST for
a playlist, falling back to OUTPUT_TEMPLATE — evaluated against the feed dict.
With the defaults that puts them in the same folder as the videos, named after
the feed, which is the Jellyfin layout #660 asked for. No new environment
variable: knowing the feed type is what makes reusing the item template
possible, and doing this after extraction is what makes the type known.
The write re-runs yt-dlp over a copy of the feed with its entries removed,
which reaches the playlist-file writing without re-extracting anything and
without touching yt-dlp's private write helpers. It runs in an executor and
never fails the add.
Nothing new appears for anyone who hasn't enabled writeinfojson /
writethumbnail, an explicit allow_playlist_files=false still turns it off, and
a failed or cancelled add no longer leaves metadata behind.
Subscription scans keep allow_playlist_files=False: a scan is a timer-driven
poll, and items it finds are queued through the download queue, which does the
writing. Previously every check interval rewrote these files.
Test doubles for __extract_info now take *args/**kwargs.
A subscription's name is captured once at subscribe time from the feed's own
title, so playlists — particularly the UULF-prefixed channel-uploads playlists
— all come back named "Videos" and stay that way. Adds an inline editor on the
Name cell, mirroring the existing title-filter edit next to it.
The update route already whitelisted `name` and update_subscription already
applied it, so this is mostly the missing UI. The backend side is validation:
the old `str(changes["name"])` accepted any type, any length and any
whitespace, for a value that is persisted and broadcast to every connected
client. validate_subscription_name now requires a string, collapses interior
whitespace to keep the label single-line, and caps it at 200 characters.
The name is display-only — it is used for the subscription list and log lines,
never for download paths — so renaming cannot move where files land.
Dependabot github-actions group update. Single-line bump in update-yt-dlp.yml,
the last v6 action left; consistent with checkout@v7 and setup-node@v7.

The endpoint accepted {ids: [x]} and then rejected anything but exactly one
id, so the schema advertised a batch it never supported. Retry is genuinely
singular: unlike the /delete, /start and /cancel batches, which act on local
state and can't meaningfully fail for one id and not another, each retry
re-extracts the URL and the caller removes that item's done record only once
it is confirmed re-queued. A real batch form would need per-id results in the
response for the caller to know which records to remove; that only becomes
worth designing alongside moving done-record deletion server-side.
/retry has not shipped yet, so there is no compatibility cost.
Replaces the client-side retry (which rebuilt an /add payload from the public
download dict) with a server-side POST /retry that re-adds from the stored
DownloadInfo. The public dict deliberately excludes `entry`, so the UI could
never carry playlist context across a retry: retried playlist items lost
playlist_index and landed in the root directory instead of their playlist
folder. The completed queue now persists the compacted entry for status=error
records only, so the context also survives a restart; successful records still
drop it. Also adds track_number to _COMPACT_ENTRY_EXTRA_KEYS so the #1031 music
metadata survives a failure/retry cycle.
Merged with two review fixes (08dccd9): retry_entry is now carried through the
url/url_transparent recursion in __add_entry, and retry() re-applies the
ALLOW_YTDL_OPTIONS_OVERRIDES and configured-preset gates that /add enforces via
parse_download_options.

Two review fixes on top of the retry endpoint:
- __add_entry dropped retry_entry when extraction returned an unprocessed
url/url_transparent result and it recursed back into add(). Since
__extract_info runs with extract_flat=True, that path is live, and a retried
playlist item taking it fell back to OUTPUT_TEMPLATE and landed in the root
directory instead of its playlist folder. The playlist child loop keeps
passing retry_entry=None on purpose: those entries get fresh playlist context
stamped on them from the current extraction.
- retry() called dqueue.add() directly, so it bypassed the
parse_download_options gates that /add applies. Stored ytdl_options_overrides
were re-applied even after ALLOW_YTDL_OPTIONS_OVERRIDES was turned off, and
preset names removed from the configuration were still passed through. Both
are re-checked against the current configuration at retry time.
Added track_number to the set of keys preserved when compacting persisted playlist entries, ensuring this metadata is retained for accurate track ordering and display.

Co-authored-by: dependabot[bot] <support@github.com>
Adds __record_add_failure so a URL that fails before a real download starts
(unsupported/unextractable URL, SSRF-rejected, extraction error) appears in the
Completed list as a red-cross entry with retry and error-detail, instead of only
a transient toast and a server log line. Keyed by info.url like any errored
download. Includes _short_title_for_failed_url for a readable hostname title.
The frontend hunk removing the 'Click for details' hint from every error row was
dropped from this merge; that affordance (added in fd3aaea, #143) is kept.

Adds MusicMetadataPreProcessor (app/music_metadata.py), a pre_process
postprocessor that enriches the info dict using only extractor-owned fields:
track-number/total resolution, album-title fallback, and square-thumbnail
preference. Track numbers and album flow into files through yt-dlp's existing
FFmpegMetadata embedding, so no per-format tag-writing code and no new
dependency. The earlier mutagen writer and its download-failing
PostProcessingError path were dropped per review.

The SSRF guard rejects any address that isn't globally routable, which breaks
proxy/VPN setups that resolve hosts into private or special-use ranges. The
reported case is Fake-IP clients (sing-box, Clash, Mihomo) that map YouTube to
the RFC 2544 benchmarking range 198.18.0.0/15 to tunnel the traffic; MeTube
rejected it with "Refusing to fetch internal address" even though yt-dlp itself
handles it fine.
Add a boolean ALLOW_PRIVATE_ADDRESSES (default false) that, when set, skips both
layers: validate_url returns after scheme validation without the internal-host
checks, and the connect-time socket guard is not installed. Threaded to the
download subprocess via Download so the guard sees it too. Scheme validation
(http/https only) still applies. Documented in the README as a trust-your-network
opt-out that disables SSRF protection.

The connect-time getaddrinfo guard added for redirect/rebinding SSRF covers
only the download subprocess: metadata extraction runs in the main process
(where a process-wide guard would reject the server's own HOST=0.0.0.0 bind),
and native curl_cffi/libcurl resolution used by --impersonate bypasses Python's
socket module. Record both in url_guard's docstring and at the extraction site
so the boundary is explicit; network isolation remains the backstop.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
validate_url only inspects the submitted URL string. yt-dlp then follows HTTP
redirects and resolves media URLs from remote metadata without re-checking, so
an allowed URL that 302s to http://169.254.169.254/ (cloud metadata) or an
RFC1918 host is still fetched — the guard's own docstring scoped this out.
Install a getaddrinfo guard in the download subprocess that re-validates every
resolved address at actual connect time, covering redirects and DNS rebinding
for any backend resolving through Python's socket module (urllib, requests).
Loopback is permitted so locally-configured proxies keep working; link-local,
RFC1918 and unique-local are blocked. Native resolvers (curl_cffi/libcurl via
--impersonate) bypass this and rely on network isolation as the backstop.

validate_url() previously returned None (allow) on socket.gaierror, so a
host that failed to resolve at check time was passed straight to yt-dlp. A
host we cannot resolve is a host we cannot verify as non-internal, and it may
resolve differently when yt-dlp fetches it. Reject it instead.

The per-download chapter_template was validated only against literal ".."
in the template string, but yt-dlp expands %(section_title)s (and every
other field) from attacker-controlled metadata at download time. On POSIX
hosts yt-dlp does not neutralise a ".." path component, so a chapter titled
".." turns a guard-passing template like
"%(section_title)s/%(section_title)s/x.%(ext)s" into "../../x.mp4" and writes
outside DOWNLOAD_DIR. The same class of escape applies to any multi-segment
output template (default/playlist/channel) whose fields resolve to "..".
The template string can never see the "..": it only exists after expansion.
So move the check to the one point every output path flows through —
YoutubeDL.prepare_filename — via a _ConfinedYoutubeDL subclass that refuses
any resolved path outside the download/temp roots (fail closed). This covers
the main file, split-chapter files, thumbnails and subtitles in one place.
With the chokepoint authoritative, the scattered ingress string checks
(chapter_template, custom_name_prefix) and the weaker _output_dir_escapes
literal-prefix check are removed. Tests move from the ingress layer to the
chokepoint, exercising the real metadata-resolution vector.

The same-day rerun path deleted and recreated the release tag within

Issue forms: trim prerequisite checkboxes to the two that matter, make the
yt-dlp test field explicitly conditional (UI bugs write "UI bug"), lead the
feature form with the scope line and the already-decided list, and retire
the question template in favor of Discussions Q&A.
Discussion forms: rename q-and-a.yml to q-a.yml so it matches the actual
category slug (it never applied), add ideas.yml for the category where
feature requests actually land, drop configuration-help.yml (no matching
category) and the inert config.yml (blank_discussions_enabled is not a
GitHub feature), and remove checkboxes from low-stakes discussion forms.
