Alexander Simmerl	d46b9afb79	Simplify WriteFileAtomic We can make the implementation more robust by adjusting our assumptions and leverage explicit file modes for syncing. Additionally we going to assume that we want to clean up and can't really recover if thos operations (file close and removal) fail. * utilise file mode for majority of concerns * improve test coverage by covering more assumptions * signature parity with ioutil.WriteFile * always clean up Replaces #160	7 years ago
Emmanuel T Odeke	97bdad8262	common: NewBitArray never crashes on negatives (#170 ) Fixes #169 Fixes https://github.com/tendermint/tendermint/issues/1322 The previous code was very trusting assuming that rational actors will use this code. However, Byzantine actors don't care and in the case of the linked issue negative lengths can be sent to this code unfettered having been received from a peer. This code is essentially just a sign change from `==` to `<=` and we've gutted out that attack by being more defensive.	7 years ago

Anton Kaliaev	52ce4c20f8	Fix RepeatTimer memory leak (#137 ) fix RepeatTimer memory leak (Refs #137) * test case * drain channels on reset Leaking memory: ``` leaktest.go:144: leaktest: leaked goroutine: goroutine 116 [chan send]: github.com/tendermint/tmlibs/common.(RepeatTimer).fireRoutine(0xc42006a410, 0xc4203403c0, 0xc42031b2c0) /go/src/github.com/tendermint/tmlibs/common/repeat_timer.go:160 +0x6e created by github.com/tendermint/tmlibs/common.(RepeatTimer).reset /go/src/github.com/tendermint/tmlibs/common/repeat_timer.go:196 +0xe9 ``` The alternative solution could be draining channels on the client side. * add one more select instead of draining thanks to Jae	7 years ago
Emmanuel Odeke	763dc21393	common/BitArray: reduce fragility with methods Fixes https://github.com/tendermint/tmlibs/issues/145 Fixes https://github.com/tendermint/tmlibs/issues/146 The code in here has been fragile when it comes to nil but these edge cases were never tested, although they've showed up in the wild and were only noticed because the reporter actually read the logs otherwise we'd have never known. This changes covers some of these cases and adds some tests.	7 years ago
Emmanuel Odeke	951333ecb0	common: IsHex should be able to handle 0X prefixed strings IsHex should also successfully decode strings prefixed with 0X instead of only 0x strings. Also add tests generally for IsHex.	7 years ago

Emmanuel Odeke	84afef20f5	common: fix BitArray.Update to avoid nil dereference Update previously only checked that the receiver was non-nil but didn't check that the input parameter to update "o" was non-nil causing a nil dereference in cases such as `fe632ea32a/consensus/reactor.go (L306)` Fixes https://github.com/tendermint/tendermint/issues/1169	7 years ago

Emmanuel Odeke	8638961f02	common: Rand* warnings about cryptographic unsafety Lesson articulated by @jaekwon on why we need 80 bits of entropy at least before we can think of cryptographic safety. math/rand's seed is a max of 64 bits so can never be cryptographically secure. Also added some benchmarks for RandBytes	7 years ago

Emmanuel Odeke	29471d75cb	common: no more relying on math/rand.DefaultSource Fixes https://github.com/tendermint/tmlibs/issues/99 Updates https://github.com/tendermint/tendermint/issues/973 Removed usages of math/rand.DefaultSource in favour of our own source that's seeded with a completely random source and is safe for use in concurrent in multiple goroutines. Also extend some functionality that the stdlib exposes such as * RandPerm * RandIntn * RandInt31 * RandInt63 Also added an integration test whose purpose is to be run as a consistency check to ensure that our results never repeat hence that our internal PRNG is uniquely seeded each time. This integration test can be triggered by setting environment variable: `TENDERMINT_INTEGRATION_TESTS=true` for example ```shell TENDERMINT_INTEGRATION_TESTS=true go test ```	7 years ago
