* plumbing: format/packfile, Fix data race and resource leak.Ed Bardsley2019-06-032-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two problems are fixed: - Buffers are not returned to the pool in the case of errors. - Per https://golang.org/pkg/bytes/#Buffer.Bytes, the slice returned from bytes.Buffer.Bytes() is only valid until the next modification of the buffer, so it must be copied before the buffer is returned to the pool. Running `go test -race` detected the following: ``` ================== WARNING: DATA RACE Write at 0x00c000224020 by goroutine 15: bytes.(*Buffer).WriteByte() /usr/local/Cellar/go/1.11.5/libexec/src/bytes/buffer.go:271 +0xc8 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.diffDelta() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/diff_delta.go:95 +0x505 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.getDelta() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/diff_delta.go:60 +0x4ae vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).tryToDeltify() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:309 +0x398 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).walk() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:262 +0x33b vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).ObjectsToPack.func1() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:70 +0x6a Previous read at 0x00c000224020 by goroutine 8: runtime.slicecopy() /usr/local/Cellar/go/1.11.5/libexec/src/runtime/slice.go:221 +0x0 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.getDelta() vendor/gopkg.in/src-d/go-git.v4/plumbing/memory.go:53 +0x5e2 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).tryToDeltify() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:309 +0x398 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).walk() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:262 +0x33b vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).ObjectsToPack.func1() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:70 +0x6a Goroutine 15 (running) created at: vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).ObjectsToPack() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:69 +0x761 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*Encoder).Encode() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/encoder.go:52 +0xb1 vendor/gopkg.in/src-d/go-git%2ev4.pushHashes.func1() vendor/gopkg.in/src-d/go-git.v4/remote.go:1026 +0x102 Goroutine 8 (finished) created at: vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*deltaSelector).ObjectsToPack() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/delta_selector.go:69 +0x761 vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile.(*Encoder).Encode() vendor/gopkg.in/src-d/go-git.v4/plumbing/format/packfile/encoder.go:52 +0xb1 vendor/gopkg.in/src-d/go-git%2ev4.pushHashes.func1() vendor/gopkg.in/src-d/go-git.v4/remote.go:1026 +0x102 ================== ``` Signed-off-by: Ed Bardsley <ewb@uber.com>
