This is a custom core dump program that will be called when a core dump
occurs. The program will save the core data in CORE_PATH and also, if a

Fix: data pending race
There is a data pending race involving late population of the streams in
the stream hash table, and applying flush on streams that are not yet
globally visible.
This is caused by the fact that streams are added to the hash table only
when received by the data-handling consumer thread.
This results in data_pending() incorrectly returning that there is no
data pending in some cases.
This has been discovered by adding 1s delay in read subbuffer function
for testing.

Fix: (slight UI change) refuse missing -c if non-default channel exists
After a user creates a channel within a session, creating a "default"
channel if a user forgets to put "-c channel_name" in the following
add-context, enable-event, disable-event commands is misleading. The
natural expected behavior would be that the command would apply the the
last enabled channel (notion of a "current" channel, like we have for
sessions), but certainly not that it creates a new channel with default
attributes behind the user's back.
An intermediate fix that would not require to keep a notion of current
channel is to refuse creation of a default channel if at least one
non-default channel has already been created in the session.
This commit affects enable-event, disable-event and add-context
commands.
This fix belongs to the 2.3-rc cycle, and cannot be backported, since
it:
a) changes the user interface of lttng (returns an error in the case
where -c name is missing and the session contains an non-default
channel)
b) changes the ABI between lttng-ctl and sessiond: a default channel is
now expressed as an empty string ('\0') rather than by "channel0",
which allows making the difference between an explicit "channel0"
channel and a default channel in the session daemon.

Support snapshot max-size limitation
This features allows the user to specify a maximum size for the snapshot

domains. The metadata is not limited and its size is not taken into
account in the maximum stream size computation.
