This prints changed state, props and params when run with -m and running
the `info` command. We try to print only things that have changed. It
would probably be good to make the props (and params) print a diff of
what's changed as well.
In order to show metadata changes when monitoring, a sync must be
triggered just like it is done for other objects, to make sure that
`dump_objects()` is called some time later and the changed metadata
objects are shown.
Otherwise metadata changes would never be displayed unless there
was a change to a different type of object, whose event handlers
do trigger a sync.
Fixes#4053
When a link already exists, the link will fail and the proxy will be
destroyed and the pointer set to NULL. Avoid doing things with the NULL
pointer when cleaning up.
Since `spa/utils/cleanup.h` is not a private header anymore, there is
no need for a separate `pipewire/cleanup.h` since the definitions of
the cleanup routines can now be moved into the respective headers.
`registry_event_global()` creates an `object` object for every object,
not just those matching `data::pattern`. However, previously
`registry_event_global_remove()` only destroyed those objects
that matched the given pattern. Fix that by destroying
every object.
Fixes#4001
Fixes 47e1f38f03 ("pw-dump: also dump object removal")
When processing the output of pw-mon in real time, it is presently
difficult to know when an event is completed because the last attribute
or property is different for each type of event.
This change corrects that by terminating each event with an empty new line.
All pw_core event handlers (`on_core_*()`) currently receive a pointer
to `struct data`, not `struct proxy_data`; as can be seen from the
`pw_core_add_listener()` call in `main()`.
Fixes: cacdcc1b62 ("pw-mon: add filter param to hide props and/or params")
Fixes#3997
Add struct spa_error_location that holds information about some parsing
context such as the line and column number, error and line fragment
with the error.
Make spa_json_get_error() fill in the spa_error_location instead. Add
some error codes to the error state and use this to add a parsing reason
to the location.
Add a debug function to log the error location in a nice way. Also
add a FILE based debug context to log to any FILE.
Replace pw_properties_check_string() with
pw_properties_update_string_checked() and add
pw_properties_new_string_checked(). The check string behaviour can still
be done by setting props to NULL but the main purpose is to be able to
avoid parsing the json file twice in the future.
When using the old pw_properties_update_string(), log a warning to the
log when we fail to parse the complete string.
Use the new checked functions and the debug functions to report about
parsing errors in the tools and conf parsing.
This gives errors like:
```
> pw-loopback --playback-props '{ foo = [ f : g ] }'
error: syntax error in --playback-props: Invalid array separator
line: 1 | { foo = [ f : g ] }
col: 14 | ^
```
Check for JSON parse errors, and log error messages as appropriate.
It's mostly enough to do this where the input is parsed for the first
time, e.g. via pw_properties_new_string, as that already validates the
JSON syntax.
If ncurses is not initialized, then the global `LINES` variable stays 0.
This will cause problems because there is an unconditional `if (y > LINES)`
check when printing the driven nodes for a given driver node, resulting
in only the first one being printed.
Commit 71653e04d2 ("pw-top: add 'batch-mode' and iterations known from top")
that introduced batch mode missed this one condition, so fix that
by only checking the for terminal overflow in non-batch mode as
it is done a couple lines above.
Fixes#3899
If a pipewire property has quotes, the DOT graph fails to be generated because
they are not escaped. This patch fixes this by escaping the quotes from a
pipewire property value before adding it to the graph
This changes avoids constantly reallocating the DOT data string every time
someting is added. We now always allocate a DOT data string of size 2048, and
we only reallocate by size * 2 if we need more data.
When the server closes the connection in non-interactive mode, we need
to set the quit flag to avoid going into second mainloop_run() that will
just block forever.
See #3837
If for some reason the proxy gets destroyed, we make sure to remove
listeners and forget the proxy pointer. We do not however delete the
target_link; we consider the proxy destruction as an error.
If another definitive state occured on the link (got to paused state,
got an error), then that event will be ignored. Else we consider it an
error.
Previously, on new node event, we registered a core sync. Linking was
attempted at core sync done but the node did not yet have time to
register its ports.
Only listen to new ports. This delays the linking attempt to when nodes
have had time to create their ports.
Stop using sync for link creation detection. Instead, listen to link
events.
We still listen to errors, link info events are not enough. For example,
if a link already exists, we only get a proxy error and no link info
event.
Now that we have a create_link_proxies() that looks for our matching
nodes/ports and creates proxies if they exist, implementing --wait is
easy.
We move the call to create_link_proxies() the core done event. If it
finds no potential nodes/ports, we keep running our loop, monitoring
new objects.
Make do_link_ports() only create proxies. Previously it ran the event
loop once per attempted link to detect link creation errors. Rename it
to create_link_proxies() to make things clear.
Created proxies are stored into a list (data->link_targets).
create_link_proxies() returns the number of link proxies created. This
can be zero when the two matching nodes have zero ports.
Refactor main() to use create_link_proxies(), ask for a sync then run
the event loop. It will stop on sync done, and we will have received
all potential link proxy errors.
Cleanup all proxies and listeners at the end of main().
Now that both the expected input and output of the resampler is placed
in the rate_match, rename the 'requested' field in pw_time to 'size'
and update the docs.
