2020-01-22docs: mention when increasing http.postBuffer is valuableLibravatar brian m. carlson1-0/+8
Users in a wide variety of situations find themselves with HTTP push problems. Oftentimes these issues are due to antivirus software, filtering proxies, or other man-in-the-middle situations; other times, they are due to simple unreliability of the network. However, a common solution to HTTP push problems found online is to increase http.postBuffer. This works for none of the aforementioned situations and is only useful in a small, highly restricted number of cases: essentially, when the connection does not properly support HTTP/1.1. Document when raising this value is appropriate and what it actually does, and discourage people from using it as a general solution for push problems, since it is not effective there.

2020-01-22doc: provide guidance on user.name formatLibravatar brian m. carlson1-1/+6
It's a frequent misconception that the user.name variable controls authentication in some way, and as a result, beginning users frequently attempt to change it when they're having authentication troubles. Document that the convention is that this variable represents some form of a human's personal name, although that is not required. In addition, address concerns about whether Unicode is supported. Use the term "personal name" as this is likely to draw the intended contrast, be applicable across cultures which may have different naming conventions, and be easily understandable to people who do not speak English as their first language. Indicate that "some form" is conventionally used, as people may use a nickname or preferred name instead of a full legal name. Point users who may be confused about authentication to an appropriate configuration option instead. Provide a shortened form of this information in the configuration option description.

2020-01-22doc: move author and committer information to git-commit(1)Libravatar brian m. carlson1-1/+1
While at one time it made perfect sense to store information about configuring author and committer information in the documentation for git commit-tree, in modern Git that operation is seldom used. Most users will use git commit and expect to find comprehensive documentation about its use in the manual page for that command. Considering that there is significant confusion about how one is to use the user.name and user.email variables, let's put as much documentation as possible into an obvious place where users will be more likely to find it. In addition, expand the environment variables section to describe their use more fully. Even though we now describe all of the options there and in the configuration settings documentation, preserve the existing text in git-commit.txt so that people can easily reason about the ordering of the various options they can use. Explain the use of the author.* and committer.* options as well. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-01-21docs: use "currently" for the present timeLibravatar brian m. carlson1-2/+2
In many languages, the adverb with the root "actual" means "at the present time." However, this usage is considered dated or even archaic in English, and for referring to events occurring at the present time, we usually prefer "currently" or "presently". "Actually" is commonly used in modern English only for the meaning of "in fact" or to express a contrast with what is expected. Since the documentation refers to the available options at the present time (that is, at the time of writing) instead of drawing a contrast, let's switch to "currently," which both is commonly used and sounds less formal than "presently."

2020-01-15gpg-interface: add minTrustLevel as a configuration optionLibravatar Hans Jerry Illikainen1-0/+15
Previously, signature verification for merge and pull operations checked if the key had a trust-level of either TRUST_NEVER or TRUST_UNDEFINED in verify_merge_signature(). If that was the case, the process die()d. The other code paths that did signature verification relied entirely on the return code from check_commit_signature(). And signatures made with a good key, irregardless of its trust level, was considered valid by check_commit_signature(). This difference in behavior might induce users to erroneously assume that the trust level of a key in their keyring is always considered by Git, even for operations where it is not (e.g. during a verify-commit or verify-tag). The way it worked was by gpg-interface.c storing the result from the key/signature status *and* the lowest-two trust levels in the `result` member of the signature_check structure (the last of these status lines that were encountered got written to `result`). These are documented in GPG under the subsection `General status codes` and `Key related`, respectively [1]. The GPG documentation says the following on the TRUST_ status codes [1]: """ These are several similar status codes: - TRUST_UNDEFINED <error_token> - TRUST_NEVER <error_token> - TRUST_MARGINAL [0 [<validation_model>]] - TRUST_FULLY [0 [<validation_model>]] - TRUST_ULTIMATE [0 [<validation_model>]] For good signatures one of these status lines are emitted to indicate the validity of the key used to create the signature. The error token values are currently only emitted by gpgsm. """ My interpretation is that the trust level is conceptionally different from the validity of the key and/or signature. That seems to also have been the assumption of the old code in check_signature() where a result of 'G' (as in GOODSIG) and 'U' (as in TRUST_NEVER or TRUST_UNDEFINED) were both considered a success. The two cases where a result of 'U' had special meaning were in verify_merge_signature() (where this caused git to die()) and in format_commit_one() (where it affected the output of the %G? format specifier). I think it makes sense to refactor the processing of TRUST_ status lines such that users can configure a minimum trust level that is enforced globally, rather than have individual parts of git (e.g. merge) do it themselves (except for a grace period with backward compatibility). I also think it makes sense to not store the trust level in the same struct member as the key/signature status. While the presence of a TRUST_ status code does imply that the signature is good (see the first paragraph in the included snippet above), as far as I can tell, the order of the status lines from GPG isn't well-defined; thus it would seem plausible that the trust level could be overwritten with the key/signature status if they were stored in the same member of the signature_check structure. This patch introduces a new configuration option: gpg.minTrustLevel. It consolidates trust-level verification to gpg-interface.c and adds a new `trust_level` member to the signature_check structure. Backward-compatibility is maintained by introducing a special case in verify_merge_signature() such that if no user-configurable gpg.minTrustLevel is set, then the old behavior of rejecting TRUST_UNDEFINED and TRUST_NEVER is enforced. If, on the other hand, gpg.minTrustLevel is set, then that value overrides the old behavior. Similarly, the %G? format specifier will continue show 'U' for signatures made with a key that has a trust level of TRUST_UNDEFINED or TRUST_NEVER, even though the 'U' character no longer exist in the `result` member of the signature_check structure. A new format specifier, %GT, is also introduced for users that want to show all possible trust levels for a signature. Another approach would have been to simply drop the trust-level requirement in verify_merge_signature(). This would also have made the behavior consistent with other parts of git that perform signature verification. However, requiring a minimum trust level for signing keys does seem to have a real-world use-case. For example, the build system used by the Qubes OS project currently parses the raw output from verify-tag in order to assert a minimum trust level for keys used to sign git tags [2].

Commit 31224cbdc7 ("clone: recursive and reference option triggers submodule alternates", 2016-08-17) taught Git to support the configuration options "submodule.alternateLocation" and "submodule.alternateErrorStrategy" on a superproject. If "submodule.alternateLocation" is configured to "superproject" on a superproject, whenever a submodule of that superproject is cloned, it instead computes the analogous alternate path for that submodule from $GIT_DIR/objects/info/alternates of the superproject, and references it. The "submodule.alternateErrorStrategy" option determines what happens if that alternate cannot be referenced. However, it is not clear that the clone proceeds as if no alternate was specified when that option is not set to "die" (as can be seen in the tests in 31224cbdc7). Therefore, document it accordingly.

The sparse-checkout feature can have quadratic performance as the number of patterns and number of entries in the index grow. If there are 1,000 patterns and 1,000,000 entries, this time can be very significant.

2019-11-14Start to implement a built-in version of `git add --interactive`Libravatar Johannes Schindelin1-0/+5
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).

For backwards-compatibility (and to prepare for a use case where submodule and multiple-remote fetches may need different parallelization limits), the config setting `submodule.fetchJobs` still only controls the submodule part of `git fetch`, while the newly-introduced setting `fetch.parallel` controls both (but can be overridden for submodules with `submodule.fetchJobs`).

2019-10-05trace2: discard new traces if target directory has too many filesLibravatar Josh Steadmon1-0/+6
trace2 can write files into a target directory. With heavy usage, this directory can fill up with files, causing difficulty for trace-processing systems. This patch adds a config option (trace2.maxFiles) to set a maximum number of files that trace2 will write to a target directory. The following behavior is enabled when the maxFiles is set to a positive integer: When trace2 would write a file to a target directory, first check whether or not the traces should be discarded. Traces should be discarded if: * there is a sentinel file declaring that there are too many files * OR, the number of files exceeds trace2.maxFiles. In the latter case, we create a sentinel file named git-trace2-discard to speed up future checks. The assumption is that a separate trace-processing system is dealing with the generated traces; once it processes and removes the sentinel file, it should be safe to generate new trace files again. The default value for trace2.maxFiles is zero, which disables the file count check. The config can also be overridden with a new environment variable: GIT_TRACE2_MAX_FILES.

The commit-graph feature is now on by default, and is being written during 'git gc' by default. Typically, Git only writes a commit-graph when a 'git gc --auto' command passes the gc.auto setting to actualy do work. This means that a commit-graph will typically fall behind the commits that are being used every day. To stay updated with the latest commits, add a step to 'git fetch' to write a commit-graph after fetching new objects. The fetch.writeCommitGraph config setting enables writing a split commit-graph, so on average the cost of writing this file is very small. Occasionally, the commit-graph chain will collapse to a single level, and this could be slow for very large repos.

2019-08-13repo-settings: create feature.experimental settingLibravatar Derrick Stolee3-2/+18
The 'feature.experimental' setting includes config options that are not committed to become defaults, but could use additional testing. Update the following config settings to take new defaults, and to use the repo_settings struct if not already using them: * 'pack.useSparse=true' * 'fetch.negotiationAlgorithm=skipping' In the case of fetch.negotiationAlgorithm, the existing logic would load the config option only when about to use the setting, so had a die() statement on an unknown string value. This is removed as now the config is parsed under prepare_repo_settings(). In general, this die() is probably misplaced and not valuable. A test was removed that checked this die() statement executed. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-08-13repo-settings: create feature.manyFiles settingLibravatar Derrick Stolee3-1/+19
The feature.manyFiles setting is suitable for repos with many files in the working directory. By setting index.version=4 and core.untrackedCache=true, commands such as 'git status' should improve. While adding this setting, modify the index version precedence tests to check how this setting overrides the default for index.version is unset.

2019-08-13commit-graph: turn on commit-graph by defaultLibravatar Derrick Stolee2-2/+2
The commit-graph feature has seen a lot of activity in the past year or so since it was introduced. The feature is a critical performance enhancement for medium- to large-sized repos, and does not significantly hurt small repos. Change the defaults for core.commitGraph and gc.writeCommitGraph to true so users benefit from this feature by default. There are several places in the test suite where the environment variable GIT_TEST_COMMIT_GRAPH is disabled to avoid reading a commit-graph, if it exists. The config option overrides the environment, so swap these. Some GIT_TEST_COMMIT_GRAPH assignments remain, and those are to avoid writing a commit-graph when a new commit is created.

2019-08-11doc: fix repeated wordsLibravatar Mark Rushakoff2-2/+2
Inspired by 21416f0a07 ("restore: fix typo in docs", 2019-08-03), I ran "git grep -E '(\b[a-zA-Z]+) \1\b' -- Documentation/" to find other cases where words were duplicated, e.g. "the the", and in most cases removed one of the repeated words. There were many false positives by this grep command, including deliberate repeated words like "really really" or valid uses of "that that" which I left alone, of course. I also did not correct any of the legitimate, accidentally repeated words in old RelNotes.

2019-08-05doc: typo: s/can not/cannot/ and s/is does/does/Libravatar Mark Rushakoff1-1/+1
"Can not" suggests one has the option to not do something, whereas "cannot" more strongly suggests something is disallowed or impossible. Noticed "can not", mistakenly used instead of "cannot" in git help glossary, then ran git grep 'can not' and found many other instances. Only files in the Documentation folder were modified. 'Can not' also occurs in some source code comments and some test assertion messages, and there is an error message and translation "can not move directory into itself" which I may fix and submit separately from the documentation change. Also noticed and fixed "is does" in git help fetch, but there are no other occurrences of that typo according to git grep.
