| | | | | | | | | | | | | | | | | | | | | | | | requests to the processing loop for CALL packets we receive from different nodes. This implements the ReadOnly and ReadWrite request processing, delegation and revoking of delegations for all requests coming in across the network from a remote node.

| | | | | | | | | | | | | | | | | | all previous delegations, add a 1 second grace/delay for any new readonly delegation requests so that the read-write fetch-lock porcess has a chance to make progress (This used to be ctdb commit 2a4e9e69850d64dd8aef695f587ebe04393a688f)
| | * ReadOnly: Add a new flag to call request packet to indicate that the client ↵Ronnie Sahlberg2011-08-231-1/+2
| | | | | | | | | | | | | | | | | | wants a readonly delegation (This used to be ctdb commit a3f54a556e97170eedf43708d58dd32446ca5840)
| | * ReadOnly: Add a function to start a revoke of all delegations for a record.Ronnie Sahlberg2011-08-232-0/+268
| | | | | | | | | | | | | | | | | | This triggers a child process to be created to perform the actual potentially blocking calls that are required. (This used to be ctdb commit 7d575ee92c95bc4aab78a33bc1aac7ff0811ab3a)
| | * ReadOnly: Add functions to register CALLs to a context used to handle ↵Ronnie Sahlberg2011-08-232-0/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | deferal of processing of CALL commands. Once the contexts are freed, the deferred calls are re-issued to the input packet processing functions again. This is needed when/if a CALL can not currently be processed by the main engine due to the record being locked down for revoking of all delegations. The data is passed through several layers of callbacks, and finally a timed event callback to ensure that the processing of the packet will be restarted again at the topmost eventloop, avoinding event loop nesting. (This used to be ctdb commit cc6f78efcfa3b8caeffbd68018e6dfbf81488dce)
| | * ReadOnly: Add an extra flag to ctdb_call_local to specify whether we want to ↵Ronnie Sahlberg2011-08-233-8/+12
| | | | | | | | | | | | | | | | | | write the record and header back to the tdb (for example we do when performing dmaster migrations) (This used to be ctdb commit b935e83255aeb3754b2fd37cf5611e02f7283514)
| | * ReadOnly: After recovering all databases, make sure to clear out the ↵Ronnie Sahlberg2011-08-231-0/+11
| | | | | | | | | | | | | | | | | | tracking database used to track delegations and revoke. This is because the recovery will implicitely result in a revoke of all delegations. (This used to be ctdb commit b5520933b9922d6af6f59f535824e1cdacb9f774)
| | * ReadOnly: Add "readonly" flag to the ctdb_db_context to indicate if this ↵Ronnie Sahlberg2011-08-232-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | database supports readonly operations or not. Add a private lock-less tdb file to the ctdb_db_context to use for tracking delegarions for records Assume all databases will support readonly mode for now and se thte flag for all databases. At later stage we will add support to control on a per database level whether delegations will be supported or not. (This used to be ctdb commit 502f86f79944df4bac9094f716e54110c511dc24)
| | * ReadOnly: After performing a recovery, clear out all flags related to ↵Ronnie Sahlberg2011-08-231-0/+5
| | | | | | | | | | | | | | | | | | readonly delegations and revoke (This used to be ctdb commit 9985a97e11688f3f688bb84e1180fd57c42077f4)
| | * Add the missing "persistent" argument to db_exist()Ronnie Sahlberg2011-08-231-1/+2
| | | | | | | | | | | | | | | | | | The API for this function has changed since the 1.2 branch where readonly locks are being merged from (This used to be ctdb commit d01b9716d3e50f4c6d102e8411f0401b0f499699)
| | * ReadOnly: Add a new command 'ctdb cattdb'. This fucntion differs from 'ctdb ↵Ronnie Sahlberg2011-08-231-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | catdb' in that 'cattdb' will always traverse the local tdb file only, while 'catdb' does a cluster traverse. Since some record flags may differ between nodes in the cluster when read only delegations are in use, cattdb is needed when you need to know the exact flag settings on the current node itself. (This used to be ctdb commit d2342b680a3a8160d903d12550b86ee21c8b277d)
| | * ReadOnly: Add printing of the record flags when we are traversing a database ↵Ronnie Sahlberg2011-08-231-0/+9

| | * ReadOnly: Add 4 new record flags to handle read only delegation and revoking ↵Ronnie Sahlberg2011-08-231-0/+4
| | | | | | | | | | | | | | | | | | of delegations (This used to be ctdb commit 875b0bede217547b51f02648b6a28a3c98b6b949)
| | * ReadOnly: add a new test tool that does a fetchlock on a record, then bunps ↵Ronnie Sahlberg2011-08-232-1/+165

| | | | | | | | | | | | | | | | | | enumerate the bitmap of nodes to where we have readonly delegations (This used to be ctdb commit bfdeda30ee0e359f06dd5714864f8beae22b0736)

| | * ReadOnly records: Add a new RPC function FETCH_WITH_HEADER.Ronnie Sahlberg2011-08-233-2/+59
| | | | | | | | | | | | | | | | | | This function differs from the old FETCH in that this function will also fetch the record header and not just the record data (This used to be ctdb commit c7196d16e8e03bb2a64be164d15a7502300eae0e)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rebase the CTDB PMDA from 1.0.114 to master: - Add tevent and ctdb_protocol includes - Handle latency metrics now stored under struct latency_counter - Add new metric for the num_recoveries counter (This used to be ctdb commit 2165a6f5117a71f9f97f46be9708fa34c037e17c)

| | * | pmda: Pull ctdb statistics once per fetchDavid Disseldorp2011-09-061-69/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ctdb statistics are pulled in the PMDA fetch callback, which results in a CTDB_CONTROL_STATISTICS call for each metric. Do this once per fetch instead, and have the per-metric callbacks pull data from the last counter cache. (This used to be ctdb commit 137b498c75c55c966999cd788f12ed9010cfed3a)
| | * | pmda: Attempt reconnects while ctdbd is unavailableDavid Disseldorp2011-09-063-51/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attempt to reconnect to ctdbd on fetch while it is unreachable. We must provide our own queue callback wrapper, as ctdb_client_read_cb() exits on transport failure. (This used to be ctdb commit 28df6fbf1273b8d095a2bc38dca6a6c35c5c31bd)
| | * | pmda: Initial ctdb pmda check-inDavid Disseldorp2011-09-0610-2/+857
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CTDB Performance Metrics Domain Agent (PMDA) is compiled when Performance Co-Pilot (PCP) header files are present. The CTDB PMDA periodically requests runtime counters from ctdbd (similar to ctdb statistics) and exports these values via PCP for capture and charting etc. (This used to be ctdb commit fe7f69d6fc37661c2f1caa11de4ed3a7940d0a2f)
| | * | client: flag local node in ctdb -Y status outputDavid Disseldorp2011-09-061-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Regular "ctdb status" output flags which node is the local node, do the same for machine readable output. (This used to be ctdb commit 3885141f37724b3dea61b45fbac38489ec356588)
| | * | client: add timeout argument to ctdb_attachDavid Disseldorp2011-09-0613-26/+42
| | | | | | | | | | | | | | | | | | | | | | | | Rather than using a fixed 2 second CTDB_CONTROL_GETDBPATH timeout. (This used to be ctdb commit 9e178671560cb95121e11d718a76b05380ecd6c5)
| | * | client: add req timeout argument to ctdb_cmdline_clientDavid Disseldorp2011-09-0611-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following connection to the local ctdbd, ctdb_cmdline_client() currently issues a CTDB_CONTROL_GET_PNN request with a fixed 3 second timeout. The ctdb cmd line client accepts a --timelimit argument for specifying a per request timeout, pass this value through to ctdb_cmdline_client() for use as a CTDB_CONTROL_GET_PNN request timeout.
