Description

I started off trying to write a TSHttpTxnCacheStateGet API to return cache lookup specific details, but, based on feed back on the IRC and dev@, changing the API to a more generic interface TSHttpTxnInfoIntGet to return any arbitrary info. The idea is to be able to use this API in the long term to support any arbitrary information related to a Txn (which can be used as the underlying piece for a framework to return txn info using custom log tags).

Below's the proposal with the info I'd like the new API return along with the API signature.

Please provide comments/suggestions.

+typedef enum {
+  TS_TXN_INFO_CACHE_HIT_RAM,
+  TS_TXN_INFO_COMPRESSED_IN_RAM,
+  TS_TXN_INFO_CACHE_HIT_RWW, // READ_WHILE_WRITE
+  TS_TXN_INFO_CACHE_OPEN_READ_TRIES,
+  TS_TXN_INFO_CACHE_OPEN_WRITE_TRIES,
+  TS_TXN_INFO_CACHE_VOLUME,
+  TS_TXN_INFO_LAST_ENTRY
+} TSHttpTxnInfoKey;
+

+/* Get Arbitrary Txn info such as cache lookup details etc as defined in TSHttpTxnInfoKey */
+/**
+   Return the particular txn info requested.
+
+   @param txnp the transaction pointer
+   @param key the requested txn info.
+   @param TSMgmtInt a pointer to a integer where the return value is stored
+
+   @return @c TS_SUCCESS if the requested info is supported, TS_ERROR otherwise
+
+*/
+tsapi TSReturnCode TSHttpTxnInfoIntGet(TSHttpTxn txnp, TSHttpTxnInfoKey key, TSMgmtInt *value);
