Remove window type check from cmd_ai_models() so fetching models works
from console. Response is shown via cons_show() when called from console,
or in the AI window when called from there.
- Remove `/ai set default-provider` command and related autocomplete logic
- Remove global `wins_get_ai()` window accessor function
- Enforce strict requirement that `/ai model`, `/ai switch`, `/ai models`, and `/ai clear` commands must be executed from within an active AI chat window
- Update `/ai start` to require `<provider>` argument
BREAKING CHANGE: `/ai model`, `/ai switch`, `/ai models`, and `/ai clear` commands now require an active AI window context. The `/ai set default-provider` command has been removed.
cmd_ai_switch() and cmd_ai_clear() mutated session fields (provider_name,
provider, model, api_key, history) on the main thread without coordination,
while _ai_request_thread() read the same fields concurrently in the worker
thread. This caused use-after-free when:
- g_free(session->model) was called between worker's read and g_strdup()
- ai_provider_unref(session->provider) freed the provider struct while
worker accessed session->provider->api_url
- ai_session_clear_history() freed the history list while worker walked it
Fix:
1. Add pthread_mutex_t lock to AISession struct to protect all session
fields from concurrent access.
2. Introduce ai_session_switch() public API that atomically switches
provider, model, and API key under the session lock. This encapsulates
all session mutations within ai_client.c so cmd_funcs.c never touches
session fields directly.
3. Have _ai_request_thread() snapshot all session state under the session
lock before making requests, using local copies for the duration of
the curl request.
4. Add ai_provider_ref()/ai_provider_unref() around _ai_generic_request_thread()
to prevent provider UAF during model-fetch requests.
5. Protect ai_session_add_message(), ai_session_clear_history(), and
ai_session_set_model() with the session lock.
No pthread.h needed in cmd_funcs.c — all locking is encapsulated within
ai_client.c via the public API. No deadlock risk from nested locks.
Files changed:
- src/ai/ai_client.h: Add lock field, ai_session_switch() declaration
- src/ai/ai_client.c: Mutex init/destroy, session mutation protection,
worker thread snapshot, provider ref management
- src/command/cmd_funcs.c: Use ai_session_switch() API, remove pthread.h
Introduce a pthread mutex to protect all AISession fields from
concurrent access between the main thread and background request
worker.
- Initialize and destroy mutex during session lifecycle
- Lock session state when modifying or reading history, model, and
provider fields
- Snapshot session state under lock in the request worker thread to
prevent UAF races during API calls
- Refactor _build_json_payload to accept direct parameters for safe
usage under lock
- Update command handlers to safely switch provider/model under lock
The org_id field was removed from AIProvider as it was no longer
populated through the command surface. The /ai set org command was
previously removed, leaving org_id as dead code.
This change removes org_id from:
- AIProvider struct definition
- ai_provider_new() and ai_provider_unref()
- ai_add_provider() API signature
- _build_curl_headers() (OpenAI-Organization header)
- cmd_ai_set() and cmd_ai_providers()
- All unit tests
src/command/cmd_funcs:11118 used a plain non-atomic ref_count++ on
ai_provider, which is a data race against concurrent
ai_provider_unref() calls using g_atomic_int_dec_and_test.
- Expose ai_provider_ref() in ai_client.h (was static)
- Replace non-atomic ref_count++ with ai_provider_ref() in cmd_ai_switch"
Rewrote internal JSON parsing to correctly handle whitespace, escaped
quotes, and strict field context extraction. This prevents incorrect
field names or provider names from being added to the model list.
Added `ai_parse_models_from_json` public API to facilitate testing.
Changed `/ai models` default behavior to always fetch fresh models.
Replaced `--refresh` flag with `--cached` to display local cache.
Added comprehensive unit tests covering OpenAI and Perplexity formats,
array format, empty/null JSON, escaped quotes, and whitespace handling.
- Introduce model caching with persistence to preferences
- Add provider default model and custom settings management
- Implement `/ai switch`, `/ai models`, and improve `/ai start`
- Add model name autocomplete for chat commands
- Update command definitions and help text
- Add unit tests for new functionality
A flat-file alternative to the SQLite chatlog backend with runtime
switching, full migration tooling, integrity verification, and a
synthetic load harness. SQLite remains the default; both backends share
one dispatch layer (db_backend_t vtable) so callers don't change.
Storage layout
- Per-contact append-only `flatlog/<account>/<contact>/history.log`
under XDG_DATA_HOME, one line per message
- Single-line file header with embedded format-version marker
(FLATFILE_FORMAT_VERSION); reader warns on missing or mismatched
marker, writer and checker stay in sync via preprocessor
stringification
- Deterministic key=value metadata (`id`, `aid`, `corrects`, `to`,
`to_res`, `read`) plus escaped body \u2014 `\|`, `\]`, `\\`, `\n`, `\r`
literals prevent log injection
- Sparse byte-offset index (FF_INDEX_STEP=500) per contact for
O(log n) time-range lookups; rebuilt on inode / size / mtime
change, extended in-place when the file just grew
- Per-contact GHashTable caches for archive_id presence and
stanza_id \u2192 from_jid mapping (O(1) MAM dedup, O(1) LMC sender
validation)
Hardening
- Path-traversal protection: JID directory name normalisation
(`@` \u2192 `_at_`, slashes and `..` rejected at construction); every
per-contact path is anchored under the account's flatlog/
directory and validated before open
- Symlink-attack protection: every fopen / open uses O_NOFOLLOW; on
ELOOP the operation aborts with an error rather than following
- Filesystem permissions: log files created with mode 0600,
directories with mode 0700; both enforced at creation, verified
on each open and reported on drift by `/history verify`
- Atomic crash-safe export: write to a temp file via mkstemp (mode
0600, random suffix, no name collisions between concurrent
exports), fsync, then rename \u2014 partial state never replaces the
live file
- Concurrency: advisory flock(LOCK_EX) held for the duration of
every write, including append from live messages and full rewrite
from export, so two profanity processes can't interleave bytes
on the same log
- DoS / abuse guards:
* FF_MAX_LINE_LEN = 10 MB \u2014 lines longer than this are rejected
at read with a warning; the parser will not allocate
unbounded memory for a single record
* FF_MAX_LMC_DEPTH = 100 \u2014 `corrects:` chain walk stops at this
depth and emits a warning, preventing a malicious correction
cycle from spinning the apply pass
* FF_VERSION_SCAN_MAX = 16 \u2014 header version probe never reads
past 16 leading comment lines, even on garbage input
* Empty / inverted byte-range early-return in page-up read path
so a malformed time filter cannot cause an unbounded scan
* Zero-entry index guard so a file whose every line failed to
parse cannot cause a NULL deref on later page-up
- LMC sender validation: an incoming correction whose sender does
not match the original message's sender is rejected at write
time and surfaced via cons_show_error; a cycle in the apply pass
is broken via a visited-set
- jid_create_from_bare_and_resource treats NULL, empty string, and
the literal "(null)" as no resource and returns a bare jid;
similar normalisation for barejid eliminates the legacy
"user@host/(null)" artefact that leaked into stored fulljids
whenever g_strdup_printf("%s", NULL) ran inside create_fulljid
Commands
- `/history switch sqlite|flatfile` \u2014 runtime backend swap, closes
the old backend and opens the new one without reconnecting
- `/history export [<jid>]` \u2014 SQLite -> flat-file, merging with any
existing flatlog (dedup keyed on a SHA-256 hash mixing stanza_id,
timestamp, from_jid, body \u2014 robust against id reuse by older
clients)
- `/history import [<jid>]` \u2014 flat-file -> SQLite, same merge
semantics, runs inside a single SQLite transaction with rollback
on per-contact failure
- `/history verify [<jid>]` \u2014 integrity check; emits a structured
list of issues (ERROR / WARNING / INFO) per file:
* file-level: missing log, wrong permissions (\u2260 0600), UTF-8
BOM present, CRLF line endings, empty file
* line-level: invalid UTF-8 (with byte offset), embedded
control characters, unparsable lines, timestamps out of
order, duplicate `id:` and `aid:` (tracked separately so a
stanza/archive id collision isn't double-reported)
* cross-line: broken `corrects:` references whose target id is
not present in the file
- `/history backend` \u2014 show currently active backend
- Active backend indicator `[sqlite]` / `[flatfile]` in the status
bar next to the JID
- Roster-JID autocomplete for verify / export / import
- export and import open a SQLite handle on demand when the
flatfile backend is currently active, so migration works
regardless of which backend is live
Tests
- Unit: database_export (parser round-trip, escape/unescape, dedup
key stability, JID normalisation), database_stress (14 cases
exercising rapid writes, large messages, deep LMC chains, MAM
dedup, concurrent contacts)
- Functional: history persistence across reconnects, export /
import round-trip with content equality, MUC migration,
timestamp normalisation across timezones
- Bench harness P1\u2013P5 (synthetic load: bulk insert, time-range
read, page-up scroll, MAM ingest, mixed workload) and failure
modes F1\u2013F17 (page-up cursor and forward-iteration symmetry,
oversized lines, MAM dedup, LMC depth and cycles, BOM/CRLF,
missing log, empty file, mtime+inode flip, broken corrects, etc.)
- All bench tests integrate with the existing make targets and
emit CSV rows for baseline comparison

Remove ai_provider_ref() from ai_list_providers() so the returned
providers do not need to be unref'd by the caller. This matches the
header docstring which states "caller must not free the list or
providers". Also update all callers (cmd_ai_providers, tests) to
remove redundant ai_provider_unref() calls.
Add an AI client module that integrates with OpenAI-compatible API
providers (OpenAI, Perplexity, and custom providers) to provide
AI-assisted responses within the profanity client.
The implementation includes:
- src/ai/ai_client.c/h: Core AI client with provider management,
session handling, and async HTTP request handling via libcurl.
Supports per-provider API keys stored in preferences, reference-
counted sessions, and conversation history tracking.
- src/ui/window.c/window_list.c: New AI window type (ProfAiWin) for
displaying AI conversations, with response streaming and error
display capabilities.
- Command integration: New `/ai` command (cmd_defs.c, cmd_funcs.c)
for creating sessions, sending prompts, and managing providers.
Provider autocomplete support in cmd_ac.c.
- Preferences integration: API keys for providers are persisted in
the preferences system (config/preferences.c).
- Unit tests: 472 lines of comprehensive tests covering provider
management, session lifecycle, JSON escaping, and autocomplete
(tests/unittests/test_ai_client.c).
Architecture decisions:
- Asynchronous design: HTTP requests run on a separate thread to
avoid blocking the main UI loop. Callbacks are invoked on the main
thread via direct function call (profanity uses ncurses, not GLib
main loop).
- Reference counting: Both AIProvider and AISession use ref counting
for safe shared ownership.
- Response size limit: 10MB cap on HTTP responses to prevent OOM.

Implement /force-encryption command to configure forced encryption
settings with on|off and policy resend-to-confirm|block options.
The changes enhance user experience by clarifying encryption requirements
and providing actionable commands. Users can now press Enter again to
confirm unencrypted messages in resend-to-confirm mode.
The synchronous `get_message_from_editor` blocked the main loop (`prof_run`) while launching an external editor like `vim`, halting network I/O in `session_process_events` and preventing incoming message reception.
Introduced `get_message_from_editor_async` for `cmd_editor` to run the editor asynchronously. It forks and execs the editor in a thread (`editor_thread`), suspending NCurses to free the terminal. The main loop skips `inp_readline` and `ui_update` via a new `background_mode` flag while the editor runs, allowing `session_process_events` to keep the connection alive.
On editor completion, `editor_process` (called per loop iteration) resumes NCurses with `ui_resize`, inserts the result into the readline buffer and clears `background_mode`.
Retained synchronous `get_message_from_editor` for ~20 existing code paths (e.g., `vcard_nickname`) to avoid breaking them.
Tested with `vim` and `nano`: confirms no rendering conflicts, messages received during editing, and seamless resume. Edge cases like editor crashes handled via error logging and seamless resume.
Instead of c&p'ing the same code again and again, put everything in a
struct and loop over it.
This also fixes `vcard` not being in included in `all`.

Before this change issuing `/quit` directly called `exit(0)` and did not
invoke all the graceful shutdown routines. Now we first try to exit from
the event loop, which includes cleaning up everything.
In case the event loop is stuck for some reason, you could try to issue a
second `/quit`, which will then directly call `exit(0)`.

`/url save $someurl` will now download to
`~/.local/share/profanity/downloads/from_jid/date/filename` instead of
`~/.local/share/profanity/downloads`.
Like this the downloaded files should be better ordered.
This will only happen for MUC and 1:1 chat windows.
Private windows might have only a nick or jid. Lets not distinguish
between those two ways. And since the nick option is unreliable to be
the same person lets just put them in the general downloads folder.
As is done with downloads from all other windows as well.
I also had the idea to make this configurable but this suits my needs
and time limits right now.
When a user added an account, set it as autoconnect and then removed

When users receive a message and a subscription request from a new

report-spam JID` they most likely want the subscription request to
vanish as well.
According to mdosch Conversations is behaving like this too.

## Summary
Partial fix for https://github.com/profanity-im/profanity/issues/1939
> When doing the same in an unencrypted (no e2ee) chat there is no Downloading… message at all but the file is downloaded.
Download a file twice with `/url save`, the second download will not print download progress to the window.
The cause is `HTTPDownload`'s `silent` variable is not initialized; so, `silent` points to a second-hand stack memory address with old data. `silent` references data, so the `if` statement will fail in **src/tools/http_download.c:206** and download progress will not print to the window.
The fix is to initialize `silent` in both encrypted and unencrypted file download scenarios.
## Testing
Valgrind: Yes
- `/url save` without OMEMO
**SUCCESS**: Try three times with the same URL and download status will display every time.
