2022-03-15core.fsync: documentation and user-friendly aggregate optionsLibravatar Neeraj Singh3-3/+65
This commit adds aggregate options for the core.fsync setting that are more user-friendly. These options are specified in terms of 'levels of safety', indicating which Git operations are considered to be sync points for durability. The new documentation is also included here in its entirety for ease of review. Signed-off-by: Neeraj Singh <neerajsi@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-03-10core.fsync: new option to harden the indexLibravatar Neeraj Singh3-6/+15
This commit introduces the new ability for the user to harden the index. In the event of a system crash, the index must be durable for the user to actually find a file that has been added to the repo and then deleted from the working tree. We use the presence of the COMMIT_LOCK flag and absence of the alternate_index_output as a proxy for determining whether we're updating the persistent index of the repo or some temporary index. We don't sync these temporary indexes. Signed-off-by: Neeraj Singh <neerajsi@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-03-10core.fsync: add configuration parsingLibravatar Neeraj Singh3-5/+82
This change introduces code to parse the core.fsync setting and configure the fsync_components variable. core.fsync is configured as a comma-separated list of component names to sync. Each time a core.fsync variable is encountered in the configuration heirarchy, we start off with a clean state with the platform default value. Passing 'none' resets the value to indicate nothing will be synced. We gather all negative and positive entries from the comma separated list and then compute the new value by removing all the negative entries and adding all of the positive entries. We issue a warning for components that are not recognized so that the configuration code is compatible with configs from future versions of Git with more repo components. Complete documentation for the new setting is included in a later patch in the series so that it can be reviewed once in final form.

2022-03-10core.fsync: introduce granular fsync control infrastructureLibravatar Neeraj Singh15-33/+97
This commit introduces the infrastructure for the core.fsync configuration knob. The repository components we want to sync are identified by flags so that we can turn on or off syncing for specific components. If core.fsyncObjectFiles is set and the core.fsync configuration also includes FSYNC_COMPONENT_LOOSE_OBJECT, we will fsync any loose objects. This picks the strictest data integrity behavior if core.fsync and core.fsyncObjectFiles are set to conflicting values. This change introduces the currently unused fsync_component helper, which will be used by a later patch that adds fsyncing to the refs backend. Actual configuration and documentation of the fsync components list are in other patches in the series to separate review of the underlying mechanism from the policy of how it's configured.

2022-03-10core.fsyncmethod: add writeout-only modeLibravatar Neeraj Singh13-8/+184
This commit introduces the `core.fsyncMethod` configuration knob, which can currently be set to `fsync` or `writeout-only`. The new writeout-only mode attempts to tell the operating system to flush its in-memory page cache to the storage hardware without issuing a CACHE_FLUSH command to the storage controller. Writeout-only fsync is significantly faster than a vanilla fsync on common hardware, since data is written to a disk-side cache rather than all the way to a durable medium. Later changes in this patch series will take advantage of this primitive to implement batching of hardware flushes. When git_fsync is called with FSYNC_WRITEOUT_ONLY, it may fail and the caller is expected to do an ordinary fsync as needed. On Apple platforms, the fsync system call does not issue a CACHE_FLUSH directive to the storage controller. This change updates fsync to do fcntl(F_FULLFSYNC) to make fsync actually durable. We maintain parity with existing behavior on Apple platforms by setting the default value of the new core.fsyncMethod option.

2022-03-10wrapper: make inclusion of Windows csprng header tightly scopedLibravatar Neeraj Singh3-11/+7
Including NTSecAPI.h in git-compat-util.h causes build errors in any other file that includes winternl.h. NTSecAPI.h was included in order to get access to the RtlGenRandom cryptographically secure PRNG. This change scopes the inclusion of ntsecapi.h to wrapper.c, which is the only place that it's actually needed. The build breakage is due to the definition of UNICODE_STRING in NtSecApi.h: #ifndef _NTDEF_ typedef LSA_UNICODE_STRING UNICODE_STRING, *PUNICODE_STRING; typedef LSA_STRING STRING, *PSTRING ; #endif LsaLookup.h: typedef struct _LSA_UNICODE_STRING { USHORT Length; USHORT MaximumLength; #ifdef MIDL_PASS [size_is(MaximumLength/2), length_is(Length/2)] #endif // MIDL_PASS PWSTR Buffer; } LSA_UNICODE_STRING, *PLSA_UNICODE_STRING; winternl.h also defines UNICODE_STRING: typedef struct _UNICODE_STRING { USHORT Length; USHORT MaximumLength; PWSTR Buffer; } UNICODE_STRING; typedef UNICODE_STRING *PUNICODE_STRING; Both definitions have equivalent layouts. Apparently these internal Windows headers aren't designed to be included together. This is an oversight in the headers and does not represent an incompatibility between the APIs.

2022-02-28test-lib: make $GIT_BUILD_DIR an absolute pathLibravatar Ævar Arnfjörð Bjarmason1-2/+3
Change the GIT_BUILD_DIR from a path like "/path/to/build/t/.." to "/path/to/build". The "TEST_DIRECTORY" here is already made an absolute path a few lines above this. We could simply do $(cd "$TEST_DIRECTORY"/.." && pwd) here, but as noted in the preceding commit the "$TEST_DIRECTORY" can't be anything except the path containing this test-lib.sh file at this point, so we can more cheaply and equally strip the "/t" off the end. This change will be helpful to LSAN_OPTIONS which will want to strip the build directory path from filenames, which we couldn't do if we had a "/.." in there.

2022-02-28test-lib: correct and assert TEST_DIRECTORY overridingLibravatar Ævar Arnfjörð Bjarmason1-5/+17
Correct a misleading comment added by me in 62f539043c7 (test-lib: Allow overriding of TEST_DIRECTORY, 2010-08-19), and add an assertion that TEST_DIRECTORY cannot point to any directory except the "t" directory in the top-level of git.git. This assertion is in effect not new, since we'd already die if that wasn't the case[1], but it and the updated commentary help to make that clearer. The existing comments were also on the wrong arms of the "if". I.e. the "allow tests to override this" was on the "test -z" arm. That came about due to a combination of 62f539043c7 and 85176d72513 (test-lib.sh: convert $TEST_DIRECTORY to an absolute path, 2013-11-17). Those earlier comments could be read as allowing the "$TEST_DIRECTORY" to be some path outside of t/. As explained in the updated comment that's impossible, rather it was meant for *tests* that ran outside of t/, i.e. the "t0000-basic.sh" tests that use "lib-subtest.sh". Those tests have a different working directory, but they set the "TEST_DIRECTORY" to the same path for bootstrapping. The comments now reflect that, and further comment on why we have a hard dependency on this. 1. https://lore.kernel.org/git/220222.86o82z8als.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-28test-lib: add GIT_SAN_OPTIONS, inherit [AL]SAN_OPTIONSLibravatar Ævar Arnfjörð Bjarmason1-4/+20
Change our ASAN_OPTIONS and LSAN_OPTIONS to set defaults for those variables, rather than punting out entirely if we already have them in the environment. We want to take any user-provided settings over our own, but we can do that by prepending our defaults to the variable. The libsanitizer options parsing has "last option wins" semantics. It's now possible to do e.g.: LSAN_OPTIONS=report_objects=1 ./t0006-date.sh And not have the "report_objects=1" setting overwrite our sensible default of "abort_on_error=1", but by prepending to the list we ensure that: LSAN_OPTIONS=report_objects=1:abort_on_error=0 ./t0006-date.sh Will take the desired "abort_on_error=0" over our default. See b0f4c9087e1 (t: support clang/gcc AddressSanitizer, 2014-12-08) for the original pattern being altered here, and 85b81b35ff9 (test-lib: set LSAN_OPTIONS to abort by default, 2017-09-05) for when LSAN_OPTIONS was added in addition to the then-existing ASAN_OPTIONS.

2022-02-27rerere-train: two fixes to the use of "git show -s"Libravatar Junio C Hamano1-1/+1
The script uses "git show -s" to display the title of the merge commit being studied, without explicitly disabling the pager, which is not a safe thing to do in a script. For example, when the pager is set to "less" with "-SF" options (-S tells the pager not to fold lines but allow horizontal scrolling to show the overly long lines, -F tells the pager not to wait if the output in its entirety is shown on a single page), and the title of the merge commit is longer than the width of the terminal, the pager will wait until the end-user tells it to quit after showing the single line. Explicitly disable the pager with this "git show" invocation to fix this. The command uses the "--pretty=format:..." format, which adds LF in between each pair of commits it outputs, which means that the label for the merge being learned from will be followed by the next message on the same line. "--pretty=tformat:..." is what we should instead, which adds LF after each commit, or a more modern way to spell it, i.e. "--format=...". This existing breakage becomes easier to see, now we no longer use the pager. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-02-24convert.c: use designated initializers for "struct stream_filter*"Libravatar Ævar Arnfjörð Bjarmason1-9/+9
Change the "struct stream_filter_vtbl" and "struct stream_filter" assignments in convert.c to use designated initializers. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-24userdiff.c: use designated initializers for "struct userdiff_driver"Libravatar Ævar Arnfjörð Bjarmason1-14/+22
Change the "struct userdiff_driver" assignmentns to use designated initializers, but let's keep the PATTERNS() and IPATTERN() convenience macros to avoid churn, but have them defined in terms of designated initializers. For the "driver_true" and "driver_false" let's have the compiler implicitly initialize most of the fields, but let's leave a redundant ".binary = 0" for "driver_true" to make it obvious that it's the opposite of the the ".binary = 1" for "driver_false".

2022-02-24object-file: use designated initializers for "struct git_hash_algo"Libravatar Ævar Arnfjörð Bjarmason1-39/+39
As with the preceding commit, change another file-level struct assignment to use designated initializers. Retain the ".name = NULL" etc. in the case of the first element of "unknown hash algorithm", to make it explicit that we're intentionally not setting those, it's not just that we forgot.

2022-02-24trace2: use designated initializers for "struct tr2_dst"Libravatar Ævar Arnfjörð Bjarmason3-3/+9
Convert the "static struct tr2_dst" assignments in trace2/* to use designated initializers. I don't think it improves readability to include the explicit 0-ing out of the fd/initialized/need_close/too_many_files members, so let's have those be initialized implicitly by the compiler.

2022-02-24trace2: use designated initializers for "struct tr2_tgt"Libravatar Ævar Arnfjörð Bjarmason3-90/+90
As with the preceding commit, change another set of file-level struct assignments to use designated initializers. As before the "= NULL" assignments are redundant, but we're keeping them for self-documentation purposes. The comments left to explain the pre-image can now be removed in favor of working code that relays the same information to the reader.

2022-02-24imap-send.c: use designated initializers for "struct imap_server_conf"Libravatar Ævar Arnfjörð Bjarmason1-11/+1
Cut down a lot on the verbosity of the "server" assignment in imap-send.c using designated initializers, only the "ssl_verify" member was being set to a non-NULL non-0 value. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
