[lttng-dev] [PATCH lttng-ust v2 0/6] Support provider duplicates and unloading

This patch set adds the support for duplicated probe providers and support for unloading probe providers using dlclose(). It allows to advance scenarios where probe providers can be upgraded during tracing. For example, during tracing the user could dlopen() a new version of a probe provider and

[lttng-dev] [PATCH lttng-ust v2 6/6] Support unloading of probe providers

With this commit, it's now possible to dlclose() a library containing an actively used probe provider. The destructor of such library will now iterate over all the sessions and over all probe definitions to unregister them from the respective callsites in the process. Signed-off-by: Francis

[lttng-dev] [PATCH lttng-ust v2 1/6] Remove duplicate provider name checks

From: Mathieu Desnoyers It's now possible to register a probe provider with a name that has already been registered. This is useful when wanting to load a new version of a shared library on a already running process. Changes are necessary in the lttng-session

[lttng-dev] [PATCH lttng-tools v2 1/5] Fix: probes should be compared strictly by events metadata

Currently, events are compared using names and signatures. Events with different payloads but identical name and signatures could lead to corrupted trace because the Session Daemon would consider them identical and give them the same event ID. Events should be compared using the name, loglevel,

[lttng-dev] [PATCH lttng-tools v2 0/5] Support probes with the same name but different event payload

This patch set allows for multiple probes with the same name to be hooked on the same callsite. Right now, the Session Daemon only considers the name and signature of the events to determine if two events are identical. This could lead to trace corruptions when two probes would have the same name

[lttng-dev] [PATCH lttng-tools v2 2/5] Fix: calling ht_{hash, match}_enum with wrong argument

ht_hash_enum and ht_match_enum are currently called with the address of the pointer to a ust_registry_enum rather than the expected pointer to a ust_registry_enum. This means that those function calls would end up using garbage for hashing and comparing. Signed-off-by: Francis Deslauriers
