2015-01-07receive-pack.c: add execute_commands_atomic functionLibravatar Stefan Beller1-1/+46
This introduces the new function execute_commands_atomic which will use one atomic transaction for all updates. The default behavior is still the old non atomic way, one ref at a time. This is to cause as little disruption as possible to existing clients. It is unknown if there are client scripts that depend on the old non-atomic behavior so we make it opt-in for now. A later patch will add the possibility to actually use the functionality added by this patch. For now use_atomic is always 0.

2015-01-07receive-pack.c: move transaction handling in a central placeLibravatar Stefan Beller1-14/+37
This moves all code related to transactions into the execute_commands_non_atomic function. This includes beginning and committing the transaction as well as dealing with the errors which may occur during the begin and commit phase of a transaction. No functional changes intended.

2015-01-07receive-pack.c: die instead of error in case of possible future bugLibravatar Stefan Beller1-3/+1
Discussion on the previous patch revealed we rather want to err on the safe side. To do so we need to stop receive-pack in case of the possible future bug when connectivity is not checked on a shallow push. Also while touching that code we considered that removing the reported refs may be harmful in some situations. Sound the message more like a "This Cannot Happen, Please Investigate!" instead of giving advice to remove refs.

2015-01-07receive-pack.c: shorten the execute_commands loop over all commandsLibravatar Stefan Beller1-16/+27
Make the main "execute_commands" loop in receive-pack easier to read by splitting out some steps into helper functions. The new helper 'should_process_cmd' checks if a ref update is unnecessary, whether due to an error having occurred or for another reason. The helper 'warn_if_skipped_connectivity_check' warns if we have forgotten to run a connectivity check on a ref which is shallow for the client which would be a bug. This will help us to duplicate less code in a later patch when we make a second copy of the "execute_commands" loop. No functional change intended.

2014-12-12expire_reflog(): treat the policy callback data as opaqueLibravatar Michael Haggerty1-36/+36
Now that expire_reflog() doesn't actually look in the expire_reflog_policy_cb data structure, we can make it opaque: * Change the callers of expire_reflog() to pass it a pointer to an entire "struct expire_reflog_policy_cb" rather than a pointer to a "struct cmd_reflog_expire_cb". * Change expire_reflog() to accept the argument as a "void *" and simply pass it through to the policy functions. * Change the policy functions, reflog_expiry_prepare(), reflog_expiry_cleanup(), and should_expire_reflog_ent(), to accept "void *cb_data" arguments and cast them back to "struct expire_reflog_policy_cb" internally.

Extract two functions, reflog_expiry_prepare() and reflog_expiry_cleanup(), from expire_reflog(). This is a further step towards separating the code for deciding on expiration policy from the code that manages the physical deletion of reflog entries. This change requires a couple of local variables from expire_reflog() to be turned into fields of "struct expire_reflog_cb". More reorganization of the callback data will follow in later commits.

Extract from expire_reflog_ent() a function that is solely responsible for deciding whether a reflog entry should be expired. By separating this "business logic" from the mechanics of actually expiring entries, we are working towards the goal of encapsulating reflog expiry within the refs API, with policy decided by a callback function passed to it by its caller.

2014-12-12expire_reflog(): use a lock_file for rewriting the reflog fileLibravatar Michael Haggerty1-19/+41
We don't actually need the locking functionality, because we already hold the lock on the reference itself, which is how the reflog file is locked. But the lock_file code can do some of the bookkeeping for us, and it is more careful than the old code here was. For example: * It correctly handles the case that the reflog lock file already exists for some reason or cannot be opened. * It correctly cleans up the lockfile if the program dies.
