2020-03-30oid_array: rename source file from sha1-arrayLibravatar Jeff King1-1/+1
We renamed the actual data structure in 910650d2f8 (Rename sha1_array to oid_array, 2017-03-31), but the file is still called sha1-array. Besides being slightly confusing, it makes it more annoying to grep for leftover occurrences of "sha1" in various files, because the header is included in so many places. Let's complete the transition by renaming the source and header files (and fixing up a few comment references). I kept the "-" in the name, as that seems to be our style; cf. fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10). We also have oidmap.h and oidset.h without any punctuation, but those are "struct oidmap" and "struct oidset" in the code. We _could_ make this "oidarray" to match, but somehow it looks uglier to me because of the length of "array" (plus it would be a very invasive patch for little gain).

2020-03-05stash: remove the stash.useBuiltin settingLibravatar Thomas Gummerer1-1/+0
Remove the stash.useBuiltin setting which was added as an escape hatch to disable the builtin version of stash first released with Git 2.22. Carrying the legacy version is a maintenance burden, and has in fact become out of date failing a test since the 2.23 release, without anyone noticing until now. So users would be getting a hint to fall back to a potentially buggy version of the tool. We used to shell out to git config to get the useBuiltin configuration to avoid changing any global state before spawning legacy-stash. However that is no longer necessary, so just use the 'git_config' function to get the setting instead. Similar to what we've done in d03ebd411c ("rebase: remove the rebase.useBuiltin setting", 2019-03-18), where we remove the corresponding setting for rebase, we leave the documentation in place, so people can refer back to it when searching for it online, and so we can refer to it in the commit message.

2020-03-05advice: revamp advise APILibravatar Heba Waly1-0/+1
Currently it's very easy for the advice library's callers to miss checking the visibility step before printing an advice. Also, it makes more sense for this step to be handled by the advice library. Add a new advise_if_enabled function that checks the visibility of advice messages before printing. Add a new helper advise_enabled to check the visibility of the advice if the caller needs to carry out complicated processing based on that value. A list of advice_settings is added to cache the config variables names and values, it's intended to replace advice_config[] and the global variables once we migrate all the callers to use the new APIs.

2020-02-10pull --rebase/remote rename: document and honor single-letter abbreviations ↵Libravatar Bert Wesarg1-0/+1
rebase types When 46af44b07d (pull --rebase=<type>: allow single-letter abbreviations for the type, 2018-08-04) landed in Git, it had the side effect that not only 'pull --rebase=<type>' accepted the single-letter abbreviations but also the 'pull.rebase' and 'branch.<name>.rebase' configurations. However, 'git remote rename' did not honor these single-letter abbreviations when reading the 'branch.*.rebase' configurations. We now document the single-letter abbreviations and both code places share a common function to parse the values of 'git pull --rebase=*', 'pull.rebase', and 'branches.*.rebase'. The only functional change is the handling of the `branch_info::rebase` value. Before it was an unsigned enum, thus the truth value could be checked with `branch_info::rebase != 0`. But `enum rebase_type` is signed, thus the truth value must now be checked with `branch_info::rebase >= REBASE_TRUE` Signed-off-by: Bert Wesarg <bert.wesarg@googlemail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-01-30Merge branch 'jk/asan-build-fix'Libravatar Junio C Hamano1-0/+3
Work around test breakages caused by custom regex engine used in libasan, when address sanitizer is used with more recent versions of gcc and clang. * jk/asan-build-fix: Makefile: use compat regex with SANITIZE=address
2020-01-16Makefile: use compat regex with SANITIZE=addressLibravatar Jeff King1-0/+3
Recent versions of the gcc and clang Address Sanitizer produce test failures related to regexec(). This triggers with gcc-10 and clang-8 (but not gcc-9 nor clang-7). Running: make CC=gcc-10 SANITIZE=address test results in failures in t4018, t3206, and t4062. The cause seems to be that when built with ASan, we use a different version of regexec() than normal. And this version doesn't understand the REG_STARTEND flag. Here's my evidence supporting that. The failure in t4062 is an ASan warning: expecting success of 4062.2 '-G matches': git diff --name-only -G "^(0{64}){64}$" HEAD^ >out && test 4096-zeroes.txt = "$(cat out)" ================================================================= ==672994==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x7fa76f672000 at pc 0x7fa7726f75b6 bp 0x7ffe41bdda70 sp 0x7ffe41bdd220 READ of size 4097 at 0x7fa76f672000 thread T0 #0 0x7fa7726f75b5 (/lib/x86_64-linux-gnu/libasan.so.6+0x4f5b5) #1 0x562ae0c9c40e in regexec_buf /home/peff/compile/git/git-compat-util.h:1117 #2 0x562ae0c9c40e in diff_grep /home/peff/compile/git/diffcore-pickaxe.c:52 #3 0x562ae0c9cc28 in pickaxe_match /home/peff/compile/git/diffcore-pickaxe.c:166 [...] In this case we're looking in a buffer which was mmap'd via reuse_worktree_file(), and whose size is 4096 bytes.

We should be able to work around it by compiling with NO_REGEX, which would use our local regexec(). But to make matters even more interesting, this isn't enough by itself. Because ASan has support from the compiler, it doesn't seem to intercept our call to regexec() at the dynamic library level. It actually recognizes when we are compiling a call to regexec() and replaces it with ASan-specific code at that point. And unlike most of our other compat code, where we might have git_mmap() or similar, the actual symbol name in the compiled compat/regex code is regexec(). So just compiling with NO_REGEX isn't enough; we still end up in libasan! We can work around that by having the preprocessor replace regexec with git_regexec (both in the callers and in the actual implementation), and we truly end up with a call to our custom regex code, even when compiling with ASan. That's probably a good thing to do anyway, as it means anybody looking at the symbols later (e.g., in a debugger) would have a better indication of which function is which. So we'll do the same for the other common regex functions (even though just regexec() is enough to fix this ASan problem).

2019-12-13Makefile: drop GEN_HDRSLibravatar Junio C Hamano1-3/+2
When ebb7baf0 ("Makefile: add a hdr-check target", 2018-09-19) implemented hdr-check target, it wanted to leave some header files exempt from the stricter check the target implements, and added GEN_HDRS macro. This however is probably a bad move for two reasons: - If we value the header cleanliness check, we eventually want to teach our header generating scripts to produce clean headers. Keeping the blanket "generated headers can be left as dirty as we want" exception does not nudge us in the right direction. - There is a list of generated header files, GENERATED_H, which is used to keep track of dependencies. Presence of GEN_HDRS that is too similarly named would confuse developers who are adding new generated header files which list to add theirs. - Even though unicode-width.h could be generated using a contrib/ script, as far as our build infrastructure is concerned, it is a source file that is tracked in the source control system. Its presence in GEN_HDRS list is doubly misleading. Get rid of GEN_HDRS, which is used only once to list the headers we do not run hdr-check test on, and instead explicitly list that the ones, either tracked or generated, that we exempt from the test. This allows GENERATED_H to be the sole "here are build artifact header files that are expendable" list, so use it in the clean target to $(RM) them. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-12-13built-in add -i: start implementing the `patch` functionality in CLibravatar Johannes Schindelin1-0/+1
In the previous steps, we re-implemented the main loop of `git add -i` in C, and most of the commands. Notably, we left out the actual functionality of `patch`, as the relevant code makes up more than half of `git-add--interactive.perl`, and is actually pretty independent of the rest of the commands. With this commit, we start to tackle that `patch` part. For better separation of concerns, we keep the code in a separate file, `add-patch.c`. The new code is still guarded behind the `add.interactive.useBuiltin` config setting, and for the moment, it can only be called via `git add -p`. The actual functionality follows the original implementation of 5cde71d64aff (git-add --interactive, 2006-12-10), but not too closely (for example, we use string offsets rather than copying strings around, and after seeing whether the `k` and `j` commands are applicable, in the C version we remember which previous/next hunk was undecided, and use it rather than looking again when the user asked to jump). As a further deviation from that commit, We also use a comma instead of a slash to separate the available commands in the prompt, as the current version of the Perl script does this, and we also add a line about the question mark ("print help") to the help text. While it is tempting to use this conversion of `git add -p` as an excuse to work on `apply_all_patches()` so that it does _not_ want to read a file from `stdin` or from a file, but accepts, say, an `strbuf` instead, we will refrain from this particular rabbit hole at this stage.

2019-11-22sparse-checkout: create builtin with 'list' subcommandLibravatar Derrick Stolee1-0/+1
The sparse-checkout feature is mostly hidden to users, as its only documentation is supplementary information in the docs for 'git read-tree'. In addition, users need to know how to edit the .git/info/sparse-checkout file with the right patterns, then run the appropriate 'git read-tree -mu HEAD' command. Keeping the working directory in sync with the sparse-checkout file requires care. Begin an effort to make the sparse-checkout feature a porcelain feature by creating a new 'git sparse-checkout' builtin. This builtin will be the preferred mechanism for manipulating the sparse-checkout file and syncing the working directory. The documentation provided is adapted from the "git read-tree" documentation with a few edits for clarity in the new context. Extra sections are added to hint toward a future change to a more restricted pattern set.

2019-11-14Start to implement a built-in version of `git add --interactive`Libravatar Johannes Schindelin1-0/+1
Unlike previous conversions to C, where we started with a built-in helper, we start this conversion by adding an interception in the `run_add_interactive()` function when the new opt-in `add.interactive.useBuiltin` config knob is turned on (or the corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and calling the new internal API function `run_add_i()` that is implemented directly in libgit.a. At this point, the built-in version of `git add -i` only states that it cannot do anything yet. In subsequent patches/patch series, the `run_add_i()` function will gain more and more functionality, until it is feature complete. The whole arc of the conversion can be found in the PRs #170-175 at https://github.com/gitgitgadget/git. The "--helper approach" can unfortunately not be used here: on Windows we face the very specific problem that a `system()` call in Perl seems to close `stdin` in the parent process when the spawned process consumes even one character from `stdin`. Which prevents us from implementing the main loop in C and still trying to hand off to the Perl script. The very real downside of the approach we have to take here is that the test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the conversion is complete (the `--helper` approach would have let it pass, even at each of the incremental conversion steps).

2019-10-06ci: also build and test with MS Visual Studio on Azure PipelinesLibravatar Johannes Schindelin1-0/+4
... because we can, now. Technically, we actually build using `MSBuild`, which is however pretty close to building interactively in Visual Studio. As there is no convenient way to run Git's test suite in Visual Studio, we unpack a Portable Git to run it, using the just-added test helper to allow running test scripts in parallel.

2019-10-02Move git_sort(), a stable sort, into into libgit.aLibravatar Johannes Schindelin1-1/+1
The `qsort()` function is not guaranteed to be stable, i.e. it does not promise to maintain the order of items it is told to consider equal. In contrast, the `git_sort()` function we carry in `compat/qsort.c` _is_ stable, by virtue of implementing a merge sort algorithm. In preparation for using a stable sort in Git's rename detection, move the stable sort into `libgit.a` so that it is compiled in unconditionally, and rename it to `git_stable_qsort()`. Note: this also makes the hack obsolete that was introduced in fe21c6b285d (mingw: reencode environment variables on the fly (UTF-16 <-> UTF-8), 2018-10-30), where we included `compat/qsort.c` directly in `compat/mingw.c` to use the stable sort.

2019-09-28Makefile: emulate compile in $(HCO) target betterLibravatar Denton Liu1-3/+9
Currently, when testing headers using `make hdr-check`, headers are directly compiled. Although this seems to test the headers, this is too strict since we treat the headers as C sources. As a result, this will cause warnings to appear that would otherwise not, such as a static variable definition intended for later use throwing a unused variable warning. In addition, on platforms that can run `make hdr-check` but require custom flags, this target was failing because none of them were being passed to the compiler. For example, on MacOS, the NO_OPENSSL flag was being set but it was not being passed into compiler so the check was failing. Fix these problems by emulating the compile process better, including test compiling dummy *.hcc C sources generated from the *.h files and passing $(ALL_CFLAGS) into the compiler for the $(HCO) target so that these custom flags can be used.

2019-09-17Makefile: run coccicheck on more source filesLibravatar Denton Liu1-6/+2
Before, when running the "coccicheck" target, only the source files which were being compiled would have been checked by Coccinelle. However, just because we aren't compiling a source file doesn't mean we have to exclude it from analysis. This will allow us to catch more mistakes, in particular ones that affect Windows-only sources since Coccinelle currently runs only on Linux. Make the "coccicheck" target run on all C sources except for those that are taken from some third-party source. We don't want to patch these files since we want them to be as close to upstream as possible so that it'll be easier to pull in upstream updates. When running a build on Arch Linux with no additional flags provided, after applying this patch, the following sources are now checked: * block-sha1/sha1.c * compat/access.c * compat/basename.c * compat/fileno.c * compat/gmtime.c * compat/hstrerror.c * compat/memmem.c * compat/mingw.c * compat/mkdir.c * compat/mkdtemp.c * compat/mmap.c * compat/msvc.c * compat/pread.c * compat/precompose_utf8.c * compat/qsort.c * compat/setenv.c * compat/sha1-chunked.c * compat/snprintf.c * compat/stat.c * compat/strcasestr.c * compat/strdup.c * compat/strtoimax.c * compat/strtoumax.c * compat/unsetenv.c * compat/win32/dirent.c * compat/win32/path-utils.c * compat/win32/pthread.c * compat/win32/syslog.c * compat/win32/trace2_win32_process_info.c * compat/win32mmap.c * compat/winansi.c * ppc/sha1.c This also results in the following source now being excluded: * compat/obstack.c Instead of generating $(FOUND_C_SOURCES) from a `$(shell $(FIND_SOURCE_FILES))` invocation, an alternative design was considered which involved converting $(FIND_SOURCE_FILES) into $(SOURCE_FILES) which would hold a list of filenames from the $(FIND_SOURCE_FILES) invocation. We would simply filter `%.c` files into $(ALL_C_SOURCES). $(SOURCE_FILES) would then be passed directly to the etags, ctags and cscope commands. We can see from the following invocation $ git ls-files '*.[hcS]' '*.sh' ':!*[tp][0-9][0-9][0-9][0-9]*' ':!contrib' | wc -c 12779 that the number of characters in this list would pose a problem on platforms with short command-line length limits (such as CMD which has a max of 8191 characters). As a result, we don't perform this change. However, we can see that the same issue may apply when running Coccinelle since $(COCCI_SOURCES) is also a list of filenames: if ! echo $(COCCI_SOURCES) | xargs $$limit \ $(SPATCH) --sp-file $< $(SPATCH_FLAGS) \ >$@+ 2>$@.log; \ This is justified since platforms that support Coccinelle generally have reasonably long command-line length limits and so we are safe for the foreseeable future.

2019-09-17Makefile: strip leading ./ in $(FIND_SOURCE_FILES)Libravatar Denton Liu1-0/+1
Currently, $(FIND_SOURCE_FILES) has two modes: if `git ls-files` is present, it will use that to enumerate the files in the repository; else it will use `$(FIND) .` to enumerate the files in the directory. There is a subtle difference between these two methods, however. With ls-files, filenames don't have a leading `./` while with $(FIND), they do. This does not currently pose a problem but in a future patch, we will be using `filter-out` to process the list of files with the assumption that there is no prefix. Unify the two possible invocations in $(FIND_SOURCE_FILES) by using sed to remove the `./` prefix in the $(FIND) case.

2019-09-17Test the progress displayLibravatar SZEDER Gábor1-0/+1
'progress.c' has seen a few fixes recently [1], and, unfortunately, some of those fixes required further fixes [2]. It seems it's time to have a few tests focusing on the subtleties of the progress display. Add the 'test-tool progress' subcommand to help testing the progress display, reading instructions from standard input and turning them into calls to the display_progress() and display_throughput() functions with the given parameters. The progress display is, however, critically dependent on timing, because it's only updated once every second or, if the toal is known in advance, every 1%, and there is the throughput rate as well. These make the progress display far too undeterministic for testing as-is. To address this, add a few testing-specific variables and functions to 'progress.c', allowing the the new test helper to: - Disable the triggered-every-second SIGALRM and set the 'progress_update' flag explicitly based in the input instructions. This way the progress line will be updated deterministically when the test wants it to be updated. - Specify the time elapsed since start_progress() to make the throughput rate calculations deterministic. Add the new test script 't0500-progress-display.sh' to check a few simple cases with and without throughput, and that a shorter progress line properly covers up the previously displayed line in different situations. [1] See commits 545dc345eb (progress: break too long progress bar lines, 2019-04-12) and 9f1fd84e15 (progress: clear previous progress update dynamically, 2019-04-12).

There is a subtle difference between these two methods, however. With ls-files, filenames don't have a leading `./` while with $(FIND), they do. This results in $(CHK_HDRS) having to substitute out the leading `./` before it uses $(LIB_H). Unify the two possible values in $(LIB_H) by using patsubst to remove the `./` prefix at its definition.

There are a few important config settings that are not loaded during git_default_config. These are instead loaded on-demand. Centralize these config options to a single scan, and store all of the values in a repo_settings struct. The values for each setting are initialized as negative to indicate "unset". This centralization will be particularly important in a later change to introduce "meta" config settings that change the defaults for these config settings.
