Wen using read_files, the Exec framework called Input::remove on the
wrong input stream: it always got called on the input stream of the
execution, not on the input stream of the current file that was being
read.
This lead to threads never being closed and file handles being kept open
until Bro is closed. This means that before this patch, every time
ActiveHTTP is used, a thread stays around and several file handles are
used.
These functions are now deprecated in favor of alternative versions that
return a vector of strings rather than a table of strings.
Deprecated functions:
- split: use split_string instead.
- split1: use split_string1 instead.
- split_all: use split_string_all instead.
- split_n: use split_string_n instead.
- cat_string_array: see join_string_vec instead.
- cat_string_array_n: see join_string_vec instead.
- join_string_array: see join_string_vec instead.
- sort_string_array: use sort instead instead.
- find_ip_addresses: use extract_ip_addresses instead.
Changed functions:
- has_valid_octets: uses a string_vec parameter instead of string_array.
Addresses BIT-924, BIT-757.
* origin/topic/struck/BIT-1277:
[ADD] Added the feature to return 0 content to the python http test server and added functionality for post requests
[ADD] added baseline for the new active-http test and added a test to check for the content-length 0 fix.
[ADD] added baseline for the new exec test and added a test to check for the empty files fix.
[FIX] exec should write an empty string when file is empty instead of the filename
[FIX] Add files to result table even if the files are empty
BIT-1277 #merged
- Do stream mode for commands done by exec module, it seems important
in some cases (e.g. ensure requested stdin is fully written).
- For cases where the raw input reader knows the child process has been
reaped, set the childpid member to a sentinel value to indicate such
so we don't later think we should kill it or wait on it anymore.
- More error checking on dup2/close calls. Set sentinel values when
closing ends of pipes to prevent double closing a fd.
- Signal flag not set when raw input reader's child exits as a result
of a signal. Left out a test for this -- might be portability issues
(e.g. Ubuntu seems to do things different regarding the exit code and
also is printing "Killed" to stderr where other platforms don't).
* origin/topic/jsiwek/exec-module:
Exec module changes/fixes.
Coverage test fixes and whitespace/doc tweaks.
Update to make Dir::monitor watch inodes instead of file names.
Updates to use new input framework mechanism to execute command line programs.
Added Exec, Dir, and ActiveHTTP modules.

- Give Dir::monitor() a param for the polling interval, so different
dirs can be monitored at different frequencies.
- Fix race in Exec::run() when reading extra output files produced by
a process -- it was possible for Exec::run() to return before all
extra output files had been fully read.
- Add test cases.
