2018-07-10convert log_ref_write_fd() to use strbufLibravatar Ben Peart2-23/+13
Since we don't care about how many bytes were written, simplify the return value logic. log_ref_write_fd() was written long before strbuf was fleshed out. Remove the old manual buffer management code and replace it with strbuf(). Also update copy_reflog_msg() which is called only by log_ref_write_fd() to use strbuf as it keeps things consistent.

2018-05-10lock_file: make function-local locks non-staticLibravatar Martin Ågren1-1/+1
Placing `struct lock_file`s on the stack used to be a bad idea, because the temp- and lockfile-machinery would keep a pointer into the struct. But after 076aa2cbd (tempfile: auto-allocate tempfiles on heap, 2017-09-05), we can safely have lockfiles on the stack. (This applies even if a user returns early, leaving a locked lock behind.) These `struct lock_file`s are local to their respective functions and we can drop their staticness. For good measure, I have inspected these sites and come to believe that they always release the lock, with the possible exception of bailing out using `die()` or `exit()` or by returning from a `cmd_foo()`. As pointed out by Jeff King, it would be bad if someone held on to a `struct lock_file *` for some reason. After some grepping, I agree with his findings: no-one appears to be doing that.

2018-05-06Replace all die("BUG: ...") calls by BUG() onesLibravatar Johannes Schindelin4-22/+22
In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro was introduced to use for reporting bugs instead of die(). It was then subsequently used to convert one single caller in 588a538ae55 (setup_git_env: convert die("BUG") to BUG(), 2017-05-12). The cover letter of the patch series containing this patch (cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not terribly clear why only one call site was converted, or what the plan is for other, similar calls to die() to report bugs.

2018-03-30refs: use chdir_notify to update cached relative pathsLibravatar Jeff King2-0/+9
Commit f57f37e2e1 (files-backend: remove the use of git_path(), 2017-03-26) introduced a regression when a relative $GIT_DIR is used in a working tree: - when we initialize the ref backend, we make a copy of get_git_dir(), which may be relative - later, we may call setup_work_tree() and chdir to the root of the working tree - further calls to the ref code will use the stored git directory, but relative paths will now point to the wrong place The new test in t1501 demonstrates one such instance (the bug causes us to write the ref update to the nonsense "relative/relative/.git"). Since setup_work_tree() now uses chdir_notify, we can just ask it update our relative paths when necessary.

2018-01-24load_contents(): don't try to mmap an empty fileLibravatar Michael Haggerty1-7/+6
We don't actually create zero-length `packed-refs` files, but they are valid and we should handle them correctly. The old code `xmmap()`ed such files, which led to an error when `munmap()` was called. So, if the `packed-refs` file is empty, leave the snapshot at its zero values and return 0 without trying to read or mmap the file. Returning 0 also makes `create_snapshot()` exit early, which avoids the technically undefined comparison `NULL < NULL`.

We can return an empty iterator not only if the `packed-refs` file is missing, but also if it is empty or if there are no references whose names succeed `prefix`. Optimize away those cases as well by moving the call to `find_reference_location()` higher in the function and checking whether the determined start position is the same as `snapshot->eof`. (This is possible now because the previous commit made `find_reference_location()` robust against empty snapshots.)

So instead of calling `ref_transaction_delete()`, which is a public function and therefore shouldn't allow the `REF_ISPRUNING` flag, change `prune_ref()` to call `ref_transaction_add_update()`, which is private to the refs module. (Note that we don't need any of the other services provided by `ref_transaction_delete()`.) This allows us to change `ref_transaction_update()` to reject the `REF_ISPRUNING` flag. Do so by adjusting `REF_TRANSACTION_UPDATE_ALLOWED_FLAGS`. Also add parentheses to its definition to avoid potential future mishaps.

2017-11-06files_transaction_prepare(): don't leak flags to packed transactionLibravatar Michael Haggerty1-2/+2
The files backend uses `ref_update::flags` for several internal flags. But those flags have no meaning to the packed backend. So when adding updates for the packed-refs transaction, only use flags that make sense to the packed backend. `REF_NODEREF` is part of the public interface, and it's logically what we want, so include it. In fact it is actually ignored by the packed backend (which doesn't support symbolic references), but that's its own business.

2017-10-30files-backend: don't rewrite the `packed-refs` file unnecessarilyLibravatar Michael Haggerty3-1/+120
Even when we are deleting references, we needn't overwrite the `packed-refs` file if the references that we are deleting only exist as loose references. Implement this optimization as follows: * Add a function `is_packed_transaction_needed()`, which checks whether a given packed-refs transaction actually needs to be carried out (i.e., it returns false if the transaction obviously wouldn't have any effect). This function must be called while holding the `packed-refs` lock to avoid races. * Change `files_transaction_prepare()` to check whether the packed-refs transaction is actually needed. If not, squelch it, but continue holding the `packed-refs` lock until the end of the transaction to avoid races. This fixes a mild regression caused by dc39e09942 (files_ref_store: use a transaction to update packed refs, 2017-09-08). Before that commit, unnecessary rewrites of `packed-refs` were suppressed by `repack_without_refs()`. But the transaction-based writing introduced by that commit didn't perform that optimization. Note that the pre-dc39e09942 code still had to *read* the whole `packed-refs` file to determine that the rewrite could be skipped, so the performance for the cases that the write could be elided was `O(N)` in the number of packed references both before and after dc39e09942. But after that commit the constant factor increased. This commit reimplements the optimization of eliding unnecessary `packed-refs` rewrites. That, plus the fact that since cfa2e29c34 (packed_ref_store: get rid of the `ref_cache` entirely, 2017-03-17) we don't necessarily have to read the whole `packed-refs` file at all, means that deletes of one or a few loose references can now be done with `O(n lg N)` effort, where `n` is the number of loose references being deleted and `N` is the total number of packed references.

2017-10-25files_transaction_prepare(): fix handling of ref lock failureLibravatar Michael Haggerty1-1/+1
Since dc39e09942 (files_ref_store: use a transaction to update packed refs, 2017-09-08), failure to lock a reference has been handled incorrectly by `files_transaction_prepare()`. If `lock_ref_for_update()` fails in the lock-acquisition loop of that function, it sets `ret` then breaks out of that loop. Prior to dc39e09942, that was OK, because the only thing following the loop was the cleanup code. But dc39e09942 added another blurb of code between the loop and the cleanup. That blurb sometimes resets `ret` to zero, making the cleanup code think that the locking was successful. Specifically, whenever * One or more reference deletions have been processed successfully in the lock-acquisition loop. (Processing the first such reference causes a packed-ref transaction to be initialized.) * Then `lock_ref_for_update()` fails for a subsequent reference. Such a failure can happen for a number of reasons, such as the old SHA-1 not being correct, lock contention, etc. This causes a `break` out of the lock-acquisition loop. * The `packed-refs` lock is acquired successfully and `ref_transaction_prepare()` succeeds for the packed-ref transaction. This has the effect of resetting `ret` back to 0, and making the cleanup code think that lock acquisition was successful. In that case, any reference updates that were processed prior to breaking out of the loop would be carried out (loose and packed), but the reference that couldn't be locked and any subsequent references would silently be ignored. This can easily cause data loss if, for example, the user was trying to push a new name for an existing branch while deleting the old name. After the push, the branch could be left unreachable, and could even subsequently be garbage-collected. This problem was noticed in the context of deleting one reference and creating another in a single transaction, when the two references D/F conflict with each other, like git update-ref --stdin <<EOF delete refs/foo create refs/foo/bar HEAD EOF This triggers the above bug because the deletion is processed successfully for `refs/foo`, then the D/F conflict causes `lock_ref_for_update()` to fail when `refs/foo/bar` is processed. In this case the transaction *should* fail, but instead it causes `refs/foo` to be deleted without creating `refs/foo`. This could easily result in data loss. The fix is simple: instead of just breaking out of the loop, jump directly to the cleanup code. This fixes some tests in t1404 that were added in the previous commit.

Update the ref transaction code to use struct object_id. Remove one NULL pointer check which was previously inserted around a dereference; since we now pass a pointer to struct object_id directly through, the code we're calling handles this for us.
