2021-04-16maintenance: respect remote.*.skipFetchAllLibravatar Derrick Stolee2-1/+10
If a remote has the skipFetchAll setting enabled, then that remote is not intended for frequent fetching. It makes sense to not fetch that data during the 'prefetch' maintenance task. Skip that remote in the iteration without error. The skip_default_update member is initialized in remote.c:handle_config() as part of initializing the 'struct remote'.

2021-04-16maintenance: use 'git fetch --prefetch'Libravatar Derrick Stolee3-15/+12
The 'prefetch' maintenance task previously forced the following refspec for each remote: +refs/heads/*:refs/prefetch/<remote>/* If a user has specified a more strict refspec for the remote, then this prefetch task downloads more objects than necessary. The previous change introduced the '--prefetch' option to 'git fetch' which manipulates the remote's refspec to place all resulting refs into refs/prefetch/, with further partitioning based on the destinations of those refspecs. Update the documentation to be more generic about the destination refs. Do not mention custom refspecs explicitly, as that does not need to be highlighted in this documentation. The important part of placing refs in refs/prefetch/ remains.

2021-04-16fetch: add --prefetch optionLibravatar Derrick Stolee3-1/+106
The --prefetch option will be used by the 'prefetch' maintenance task instead of sending refspecs explicitly across the command-line. The intention is to modify the refspec to place all results in refs/prefetch/ instead of anywhere else. Create helper method filter_prefetch_refspec() to modify a given refspec to fit the rules expected of the prefetch task: * Negative refspecs are preserved. * Refspecs without a destination are removed. * Refspecs whose source starts with "refs/tags/" are removed. * Other refspecs are placed within "refs/prefetch/". Finally, we add the 'force' option to ensure that prefetch refs are replaced as necessary. There are some interesting cases that are worth testing. An earlier version of this change dropped the "i--" from the loop that deletes a refspec item and shifts the remaining entries down. This allowed some refspecs to not be modified. The subtle part about the first --prefetch test is that the "refs/tags/*" refspec appears directly before the "refs/heads/bogus/*" refspec. Without that "i--", this ordering would remove the "refs/tags/*" refspec and leave the last one unmodified, placing the result in "refs/heads/*". It is possible to have an empty refspec. This is typically the case for remotes other than the origin, where users want to fetch a specific tag or branch. To correctly test this case, we need to further remove the upstream remote for the local branch. Thus, we are testing a refspec that will be deleted, leaving nothing to fetch.

2021-04-06maintenance: simplify prefetch logicLibravatar Derrick Stolee1-25/+8
The previous logic filled a string list with the names of each remote, but instead we could simply run the appropriate 'git fetch' data directly in the remote iterator. Do this for reduced code size, but also because it sets up an upcoming change to use the remote's refspec. This data is accessible from the 'struct remote' data that is now accessible in fetch_remote(). Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In 56c6910028a (fsmonitor: change last update timestamp on the index_state to opaque token, 2020-01-07), we forgot to adjust `discard_index()` to release the "last-update" token: it is no longer a 64-bit number, but a free-form string that has been allocated.

2021-03-17fsmonitor: fix memory corruption in some corner casesLibravatar Johannes Schindelin1-2/+2
In 56c6910028a (fsmonitor: change last update timestamp on the index_state to opaque token, 2020-01-07), we forgot to adjust the part of `unpack_trees()` that copies the FSMonitor "last-update" information that we copy from the source index to the result index since 679f2f9fdd2 (unpack-trees: skip stat on fsmonitor-valid files, 2019-11-20). Since the "last-update" information is no longer a 64-bit number, but a free-form string that has been allocated, we need to duplicate it rather than just copying it. This is important because there _are_ cases when `unpack_trees()` will perform a oneway merge that implicitly calls `refresh_fsmonitor()` (which will allocate that "last-update" token). This happens _after_ that token was copied into the result index. However, we _then_ call `check_updates()` on that index, which will _also_ call `refresh_fsmonitor()`, accessing the "last-update" string, which by now would be released already. In the instance that lead to this patch, this caused a segmentation fault during a lengthy, complicated rebase involving the todo command `reset` that (crucially) had to updated many files. Unfortunately, it seems very hard to trigger that crash, therefore this patch is not accompanied by a regression test.

2021-03-17bisect: peel annotated tags to commitsLibravatar Jeff King2-1/+20
This patch fixes a bug where git-bisect doesn't handle receiving annotated tags as "git bisect good <tag>", etc. It's a regression in 27257bc466 (bisect--helper: reimplement `bisect_state` & `bisect_head` shell functions in C, 2020-10-15). The original shell code called: sha=$(git rev-parse --verify "$rev^{commit}") || die "$(eval_gettext "Bad rev input: \$rev")" which will peel the input to a commit (or complain if that's not possible). But the C code just calls get_oid(), which will yield the oid of the tag. The fix is to peel to a commit. The error message here is a little non-idiomatic for Git (since it starts with a capital). I've mostly left it, as it matches the other converted messages (like the "Bad rev input" we print when get_oid() fails), though I did add an indication that it was the peeling that was the problem. It might be worth taking a pass through this converted code to modernize some of the error messages. Note also that the test does a bare "grep" (not i18ngrep) on the expected "X is the first bad commit" output message. This matches the rest of the test script.

4f37d45706 ("clone: respect remote unborn HEAD", 2021-02-05) introduces a new feature (if the remote has an unborn HEAD, e.g. when the remote repository is empty, use it as the name of the branch) that only works in protocol v2, but did not ensure that one of its tests always uses protocol v2, and thus that test would fail if GIT_TEST_PROTOCOL_VERSION=0 (or 1) is used. Therefore, add "-c protocol.version=2" to the appropriate test. (The rest of the tests from that commit have "-c protocol.version=2" already added.)

2021-03-17fsmonitor: avoid global-buffer-overflow READ when checking trivial responseLibravatar Andrzej Hunt1-3/+3
query_result can be be an empty strbuf (STRBUF_INIT) - in that case trying to read 3 bytes triggers a buffer overflow read (as query_result.buf = '\0'). Therefore we need to check query_result's length before trying to read 3 bytes. This overflow was introduced in: 940b94f35c (fsmonitor: log invocation of FSMonitor hook to trace2, 2021-02-03) It was found when running the test-suite against ASAN, and can be most easily reproduced with the following command: make GIT_TEST_OPTS="-v" DEFAULT_TEST_TARGET="t7519-status-fsmonitor.sh" \ SANITIZE=address DEVELOPER=1 test ==2235==ERROR: AddressSanitizer: global-buffer-overflow on address 0x0000019e6e5e at pc 0x00000043745c bp 0x7fffd382c520 sp 0x7fffd382bcc8 READ of size 3 at 0x0000019e6e5e thread T0 #0 0x43745b in MemcmpInterceptorCommon(void*, int (*)(void const*, void const*, unsigned long), void const*, void const*, unsigned long) /home/abuild/rpmbuild/BUILD/llvm-11.0.0.src/build/../projects/compiler-rt/lib/asan/../sanitizer_common/sanitizer_common_interceptors.inc:842:7 #1 0x43786d in bcmp /home/abuild/rpmbuild/BUILD/llvm-11.0.0.src/build/../projects/compiler-rt/lib/asan/../sanitizer_common/sanitizer_common_interceptors.inc:887:10 #2 0x80b146 in fsmonitor_is_trivial_response /home/ahunt/oss-fuzz/git/fsmonitor.c:192:10 #3 0x80b146 in query_fsmonitor /home/ahunt/oss-fuzz/git/fsmonitor.c:175:7 #4 0x80a749 in refresh_fsmonitor /home/ahunt/oss-fuzz/git/fsmonitor.c:267:21 #5 0x80bad1 in tweak_fsmonitor /home/ahunt/oss-fuzz/git/fsmonitor.c:429:4 #6 0x90f040 in read_index_from /home/ahunt/oss-fuzz/git/read-cache.c:2321:3 #7 0x8e5d08 in repo_read_index_preload /home/ahunt/oss-fuzz/git/preload-index.c:164:15 #8 0x52dd45 in prepare_index /home/ahunt/oss-fuzz/git/builtin/commit.c:363:6 #9 0x52a188 in cmd_commit /home/ahunt/oss-fuzz/git/builtin/commit.c:1588:15 #10 0x4ce77e in run_builtin /home/ahunt/oss-fuzz/git/git.c:453:11 #11 0x4ccb18 in handle_builtin /home/ahunt/oss-fuzz/git/git.c:704:3 #12 0x4cb01c in run_argv /home/ahunt/oss-fuzz/git/git.c:771:4 #13 0x4cb01c in cmd_main /home/ahunt/oss-fuzz/git/git.c:902:19 #14 0x6aca8d in main /home/ahunt/oss-fuzz/git/common-main.c:52:11 #15 0x7fb027bf5349 in __libc_start_main (/lib64/libc.so.6+0x24349) #16 0x4206b9 in _start /home/abuild/rpmbuild/BUILD/glibc-2.26/csu/../sysdeps/x86_64/start.S:120 0x0000019e6e5e is located 2 bytes to the left of global variable 'strbuf_slopbuf' defined in 'strbuf.c:51:6' (0x19e6e60) of size 1 'strbuf_slopbuf' is ascii string '' 0x0000019e6e5e is located 126 bytes to the right of global variable 'signals' defined in 'sigchain.c:11:31' (0x19e6be0) of size 512 SUMMARY: AddressSanitizer: global-buffer-overflow /home/abuild/rpmbuild/BUILD/llvm-11.0.0.src/build/../projects/compiler-rt/lib/asan/../sanitizer_common/sanitizer_common_interceptors.inc:842:7 in MemcmpInterceptorCommon(void*, int (*)(void const*, void const*, unsigned long), void const*, void const*, unsigned long) Shadow bytes around the buggy address: 0x000080334d70: f9 f9 f9 f9 00 f9 f9 f9 f9 f9 f9 f9 00 00 00 00 0x000080334d80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x000080334d90: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x000080334da0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x000080334db0: 00 00 00 00 00 00 00 00 00 00 00 00 f9 f9 f9 f9 =>0x000080334dc0: f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9[f9]01 f9 f9 f9 0x000080334dd0: f9 f9 f9 f9 03 f9 f9 f9 f9 f9 f9 f9 02 f9 f9 f9 0x000080334de0: f9 f9 f9 f9 00 f9 f9 f9 f9 f9 f9 f9 04 f9 f9 f9 0x000080334df0: f9 f9 f9 f9 01 f9 f9 f9 f9 f9 f9 f9 00 00 00 00 0x000080334e00: f9 f9 f9 f9 00 00 00 00 f9 f9 f9 f9 01 f9 f9 f9 0x000080334e10: f9 f9 f9 f9 04 f9 f9 f9 f9 f9 f9 f9 00 f9 f9 f9 Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb Shadow gap: cc Signed-off-by: Andrzej Hunt <ajrhunt@google.com> Acked-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-03-13mergetool: do not enable hideResolved by defaultLibravatar Jonathan Nieder2-8/+3
When 98ea309b3f (mergetool: add hideResolved configuration, 2021-02-09) introduced the mergetool.hideResolved setting to reduce the clutter in viewing non-conflicted sections of files in a mergetool, it enabled it by default, explaining: No adverse effects were noted in a small survey of popular mergetools[1] so this behavior defaults to `true`. In practice, alas, adverse effects do appear. A few issues: 1. No indication is shown in the UI that the base, local, and remote versions shown have been modified by additional resolution. This is inherent in the design: the idea of mergetool.hideResolved is to convince a mergetool that expects pristine local, base, and remote files to show partially resolved verisons of those files instead; there is no additional source of information accessible to the mergetool to see where the resolution has happened. (By contrast, a mergetool generating the partial resolution from conflict markers for itself would be able to hilight the resolved sections with a different color.) A user accustomed to seeing the files without partial resolution gets no indication that this behavior has changed when they upgrade Git. 2. If the computed merge did not line up the files correctly (for example due to repeated sections in the file), the partially resolved files can be misleading and do not have enough information to reconstruct what happened and compute the correct merge result. 3. Resolving a conflict can involve information beyond the textual conflict. For example, if the local and remote versions added overlapping functionality in different ways, seeing the full unresolved versions of each alongside the base gives information about each side's intent that makes it possible to come up with a resolution that combines those two intents. By contrast, when starting with partially resolved versions of those files, one can produce a subtly wrong resolution that includes redundant extra code added by one side that is not needed in the approach taken on the other. All that said, a user wanting to focus on textual conflicts with reduced clutter can still benefit from mergetool.hideResolved=true as a way to deemphasize sections of the code that resolve cleanly without requiring any changes to the invoked mergetool. The caveats described above are reduced when the user has explicitly turned this on, because then the user is aware of them. Flip the default to 'false'.

The code to fsck objects received across multiple packs during a single git fetch session has been broken when the packfile URI feature was in use. A workaround has been added by disabling the codepath to avoid keeping a packfile that is too small. * jt/transfer-fsck-across-packs-fix: fetch-pack: do not mix --pack_header and packfile uri

2021-03-08Makefile: update 'make fuzz-all' docs to reflect modern clangLibravatar Andrzej Hunt1-3/+3
Clang no longer produces a libFuzzer.a. Instead, you can include libFuzzer by using -fsanitize=fuzzer. Therefore we should use that in the example command for building fuzzers. We also add -fsanitize=fuzzer-no-link to the CFLAGS to ensure that all the required instrumentation is added when compiling git [1], and remove -fsanitize-coverage=trace-pc-guard as it is deprecated. I happen to have tested with LLVM 11 - however -fsanitize=fuzzer appears to work in a wide range of reasonably modern clangs. (On my system: what used to be libFuzzer.a now lives under the following path, which is tricky albeit not impossible for a novice such as myself to find: /usr/lib64/clang/11.0.0/lib/linux/libclang_rt.fuzzer-x86_64.a ) [1] https://releases.llvm.org/11.0.0/docs/LibFuzzer.html#fuzzer-usage Signed-off-by: Andrzej Hunt <ajrhunt@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-03-08fix xcalloc() argument orderLibravatar René Scharfe6-17/+28
Pass the number of elements first and ther size second, as expected by xcalloc(). Provide a semantic patch, which was actually used to generate the rest of this patch. The semantic patch would generate flip-flop diffs if both arguments are sizeofs. We don't have such a case, and it's hard to imagine the usefulness of such an allocation. If it ever occurs then we could deal with it by duplicating the rule in the semantic patch to make it cancel itself out, or we could change the code to use CALLOC_ARRAY.
