Detailed Description

Check for running processes which access deleted executables or libraries.

Executed after commit, this gives a hint which processes/services need to be restarted.

Per default upon construction or explicit call to check, information about running processes which access deleted files or libraries is collected and provided as a ProcInfo container.

Provides support for reproducing check results from a foreign system by creating a debug output file containing all required information, enabled by setDebugOutputFile.
This data file can be used as datasource when passed to check(const Pathname &, bool).

Constructor & Destructor Documentation

◆ CheckAccessDeleted()

zypp::CheckAccessDeleted::CheckAccessDeleted ( bool  doCheck_r = true)

Default ctor performs check immediately.

Pass false and the initial check is omitted.

Exceptions
Exceptionif check throws.

Member Function Documentation

◆ check() [1/2]

CheckAccessDeleted::size_type zypp::CheckAccessDeleted::check ( bool  verbose_r = false)

Check for running processes which access deleted executables or libraries.

Per default check will try guess and collect executables and libraries only by looking at the files path and name. (e.g named lib* or located in *bin/).

A verbose check will omit this test and collect all processes using any deleted file.

Returns
the number of processes found.
Exceptions
ExceptionOn error collecting the data (e.g. no lsof installed)

◆ check() [2/2]

CheckAccessDeleted::size_type zypp::CheckAccessDeleted::check ( const Pathname lsofOutput_r,
bool  verbose_r = false 
)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Performs the same checks but instead of investigating the current system it uses information from lsofOutput_r to support debugging.

◆ findService()

std::string zypp::CheckAccessDeleted::findService ( pid_t  pid_r)
