2001-Nov-07 14:05    1.14    Check-in [1260]: Hell, I've seldom seen that it is needed to prepare and adjust such a lot of subtle details of existing code in order to make a new feature implementable in a straight-forward way. Anyway, here comes one more preparation change for the forthcoming channel tree specification parser:

- change l2_util_setparam() to take an l2_env_t parameter which allows the function to report better error messages.

- completely rewrite l2_util_setparam() to support calls l2_channel_configure(ch, "n1=v1,n2=v2,n3=v3") and/or l2_channel_configure(ch, "n1=%x,n2=%x,n3=%x", v1, v2, v3) instead of l2_channel_configure(ch, "n1,n2,n3", v1, v2, v3) 

  This is both a step forward to make the interface of
  l2_channel_configure() more flexible (because one now can directly
  inline values instead of having them to be passed explicitly) and
  allows the spec parser not having to know the type (integer, floating
  point or string) of a parameter (which is important if one wants the
  parser to be independent of the implementing channel handlers).

2001-Nov-07 12:37    1.13    Check-in [1259]: More preparations for forthcoming channel tree specification parser (especially to allow the parser to determine the handler structure from a handler name without introducing another and this way redundant sub-API):

- add "char *name" to l2_handler_t in order to tag each handler structure with the corresponding channel name

- add l2_env_handler() function to add handler to l2_env_t objects. All l2_handler_xxxx are automatically pre-configured there after l2_env_create().

- change l2_channel_create() to take a "const char *name" (handler name) instead of the "l2_handler_t *h" (handler pointer) to make the stuff consistent and more clear.

- adjust l2_test.c to reflect the changes. By rse. (diff)

2001-Nov-04 14:21    1.12    Check-in [1248]: Channel-Only Revamping Step 2: - moved code of l2_stream.c into (new) l2_env.c and l2_channel.c - created new l2_env_t and l2_env_xxx() - changed l2_xx_create() functions to also return l2_result_t - moved error handling into l2_env_t - replaced l2_channel_stack() with two new and more flexible l2_channel_link() and l2_channel_unlink() functions - rewritten test stuff in l2_test.c to use new structure - added new l2_channel_env() function for retriving l2_env_t

Puhhh.... By rse. (diff)

2001-Nov-03 23:51    1.11    Check-in [1247]: Channel-Only Revamping Step 1: allow multiple downstream channels in order to approach the later tree-like channel-only structure. By rse. (diff)
2001-Sep-28 16:28    1.10    Check-in [1044]: Fixed bug of incorrectly checking the result of a call to pcre_study(), and later testing the return of pcre_exec(). Added code to test the filter channel. By ms. (diff)
2001-Sep-25 11:35    1.9    Check-in [1033]: Blindly implement the regex-based filter channel. This is still not tested. By rse. (diff)
2001-Sep-12 11:42    1.8    Check-in [951]: Upgraded both stream and channel-level APIs to include new L2_LEVEL parameter design. By ms. (diff)
2001-Sep-05 09:47    1.7    Check-in [852]: Be politically correct: channels are intended to be implemented also by users, which have only access to the public API (l2.h), so do not even try to use anything more in our own shipped channels. By rse. (diff)
2001-Sep-04 21:18    1.6    Check-in [847]: Be pedantically correct: handler hooks return "l2_result_t" and not "int", although currently it is just an int/enum. By rse. (diff)
2001-Sep-04 17:41    1.5    Check-in [843]: Revamp channel handler API:

Instead of passing the downstream channel to all channels we instead provide a l2_channel_downstream() function and provide the current channel. This way the handler API is prototype-wise fully orthogonal with the channel API (which it implements) and we no longer pass information to 2/3 of our (output) channels which is of no use there.

Additionally add a channel type field to l2_handler_t which allows a handler to say what type of channel it implements (filter or output). This information is now used in l2_channel_stack() to make sure that one can only stack a filter channel on top of another channel. For convinience reasons there is also a new l2_channel_type() function which allows one to query the type of a particular channel. By rse. (diff)
