All types (besides EntropyVal) now support a native copy operation,
which uses primitives of the underlying datatypes to perform a quick
copy, without serialization.
EntropyVal is the one exception - since that type is rather complex
(many members) and will probably not be copied a lot, if at all, it
makes sense to just use the serialization function.
This will have to be slightly re-written in the near-term-future to use
the new serialization function for that opaque type.
This change also introduces a new x509_from_der bif, which allows to
parse a der into an opaque of x509.
This change removes the d2i_X509_ wrapper function; this was a remnant
when d2i_X509 took non-const arguments. We directly use d2i_X509 at
several places assuming const-ness, so there does not seem to ba a
reason to keep the wrapper.
This change also exposed a problem in the File cache - cases in which an
object was brought back into the cache, and writing occurred in the
file_open event were never correctly handeled as far as I can tell.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
- Unserializing files that were previously kicked out of the open-file
cache would cause them to be fopen'd with the original access
permissions which is usually 'w' and causes truncation. They
are now opened in 'a' mode. (addresses #780)
- Add 'max_files_in_cache' script option to manually set the maximum
amount of opened files to keep cached. Mainly this just helped
to create a simple test case for the above change.
- Remove unused NO_HAVE_SETRLIMIT preprocessor switch.
- On systems that don't enforce a limit on number of files opened for
the process, raise default max size of open-file cache from
32 to 512.
