2018-12-28t/helper/test-repository: celebrate independence from the_repositoryLibravatar Stefan Beller1-0/+10
dade47c06c (commit-graph: add repo arg to graph readers, 2018-07-11) brought more independence from the_repository to the commit graph, however it was not completely independent of the_repository, as the previous patches show. To ensure we're not accessing the_repository by accident, we'd ideally assign NULL to the_repository to trigger a segfault on access. We currently have a temporary hack in cache.h, which relies on the_hash_algo (which is a short form of the_repository->hash_algo) to be set, so we cannot do that. The next best thing is to set all fields of the_repository to 0, so any accidental access is more likely to be found.

2018-12-05repository: repo_submodule_init to take a submodule structLibravatar Stefan Beller1-3/+5
When constructing a struct repository for a submodule for some revision of the superproject where the submodule is not contained in the index, it may not be present in the working tree currently either. In that situation giving a 'path' argument is not useful. Upgrade the repo_submodule_init function to take a struct submodule instead. The submodule struct can be obtained via submodule_from_{path, name} or an artificial submodule struct can be passed in. While we are at it, rename the repository struct in the repo_submodule_init function, which is to be initialized, to a name that is not confused with the struct submodule as easily. Perform such renames in similar functions as well. Also move its documentation into the header file.

2018-11-14Add a base implementation of SHA-256 supportLibravatar brian m. carlson3-0/+9
SHA-1 is weak and we need to transition to a new hash function. For some time, we have referred to this new function as NewHash. Recently, we decided to pick SHA-256 as NewHash. The reasons behind the choice of SHA-256 are outlined in the thread starting at [1] and in the commit history for the hash function transition document. Add a basic implementation of SHA-256 based off libtomcrypt, which is in the public domain. Optimize it and restructure it to meet our coding standards. Pull in the update and final functions from the SHA-1 block implementation, as we know these function correctly with all compilers. This implementation is slower than SHA-1, but more performant implementations will be introduced in future commits. Wire up SHA-256 in the list of hash algorithms, and add a test that the algorithm works correctly. Note that with this patch, it is still not possible to switch to using SHA-256 in Git. Additional patches are needed to prepare the code to handle a larger hash algorithm and further test fixes are needed.

2018-11-06assert NOARG/NONEG behavior of parse-options callbacksLibravatar Jeff King1-0/+1
When we define a parse-options callback, the flags we put in the option struct must match what the callback expects. For example, a callback which does not handle the "unset" parameter should only be used with PARSE_OPT_NONEG. But since the callback and the option struct are not defined next to each other, it's easy to get this wrong (as earlier patches in this series show). Fortunately, the compiler can help us here: compiling with -Wunused-parameters can show us which callbacks ignore their "unset" parameters (and likewise, ones that ignore "arg" expect to be triggered with PARSE_OPT_NOARG). But after we've inspected a callback and determined that all of its callers use the right flags, what do we do next? We'd like to silence the compiler warning, but do so in a way that will catch any wrong calls in the future. We can do that by actually checking those variables and asserting that they match our expectations. Because this is such a common pattern, we'll introduce some helper macros. The resulting messages aren't as descriptive as we could make them, but the file/line information from BUG() is enough to identify the problem (and anyway, the point is that these should never be seen). Each of the annotated callbacks in this patch triggers -Wunused-parameters, and was manually inspected to make sure all callers use the correct options (so none of these BUGs should be triggerable).

2018-11-06parse-options: drop OPT_DATE()Libravatar Jeff King1-1/+0
There are no users of OPT_DATE except for test-parse-options; its only caller went away in 27ec394a97 (prune: introduce OPT_EXPIRY_DATE() and use it, 2013-04-25). It also has a bug: it does not specify PARSE_OPT_NONEG, but its callback does not respect the "unset" flag, and will feed NULL to approxidate() and segfault. Probably this should be marked with NONEG, or the callback should set the timestamp to some sentinel value (e.g,. "0", or "(time_t)-1"). But since there are no callers, deleting it means we don't even have to think about what the right behavior should be.

The get_reachable_subset() method returns the list of commits in the 'to' array that are reachable from at least one commit in the 'from' array. Add tests that check this method works in a few cases: 1. All commits in the 'to' list are reachable. This exercises the early-termination condition. 2. Some commits in the 'to' list are reachable. This exercises the loop-termination condition. 3. No commits in the 'to' list are reachable. This exercises the NULL return condition.

When consuming a priority queue, it can be convenient to inspect the next object that will be dequeued without actually dequeueing it. Our existing library did not have such a 'peek' operation, so add it as prio_queue_peek(). Add a reference-level comparison in t/helper/test-prio-queue.c so this method is exercised by t0009-prio-queue.sh. Further, add a test that checks the behavior when the compare function is NULL (i.e. the queue becomes a stack).

Add also a test to document that reading the submoudles config of nested submodules does not work yet when the .gitmodules file is not in the working tree but it still in the index. This is because the git API does not always make it possible access the object store of an arbitrary repository (see get_oid() usage in config_from_gitmodules()).

2018-08-30test-delta: read input into a heap bufferLibravatar Jeff King1-4/+4
We currently read the input to test-delta by mmap()-ing it. However, memory-checking tools like valgrind and ASan are less able to detect reads/writes past the end of an mmap'd buffer, because the OS is likely to give us extra bytes to pad out the final page size. So instead, let's read into a heap buffer. As a bonus, this also makes it possible to write tests with empty bases, as mmap() will complain about a zero-length map. This is based on a patch by Jann Horn <jannh@google.com> which actually aligned the data at the end of a page, and followed it with another page marked with mprotect(). That would detect problems even without a tool like ASan, but it was significantly more complex and may have introduced portability problems. By comparison, this approach pushes the complexity onto existing memory-checking tools. Note that this could be done even more simply by using strbuf_read_file(), but that would defeat the purpose: strbufs generally overallocate (and at the very least include a trailing NUL which we do not care about), which would defeat most memory checkers.

2018-08-29convert "oidcmp() != 0" to "!oideq()"Libravatar Jeff King1-1/+1
This is the flip side of the previous two patches: checking for a non-zero oidcmp() can be more strictly expressed as inequality. Like those patches, we write "!= 0" in the coccinelle transformation, which covers by isomorphism the more common: if (oidcmp(E1, E2)) As with the previous two patches, this patch can be achieved almost entirely by running "make coccicheck"; the only differences are manual line-wrap fixes to match the original code. There is one thing to note for anybody replicating this, though: coccinelle 1.0.4 seems to miss the case in builtin/tag.c, even though it's basically the same as all the others. Running with 1.0.7 does catch this, so presumably it's just a coccinelle bug that was fixed in the interim. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-07-20test-reach: test commit_containsLibravatar Derrick Stolee1-0/+12
The commit_contains method has two modes which depend on the given ref_filter struct. We have the "normal" algorithm (which is also the typically-slow operation) and the "tag" algorithm. This difference is essentially what changes performance for 'git branch --contains' versus 'git tag --contains'. There are thoughts that the data shapes used by these two applications justify the different implementations. Create tests using 'test-tool reach commit_contains [--tag]' to cover both methods.
