2021-12-20branch: add flags and config to inherit trackingJosh Steadmon16-23/+205
It can be helpful when creating a new branch to use the existing tracking configuration from the branch point. However, there is currently not a method to automatically do so. Teach git-{branch,checkout,switch} an "inherit" argument to the "--track" option. When this is set, creating a new branch will cause the tracking configuration to default to the configuration of the branch point, if set. For example, if branch "main" tracks "origin/main", and we run `git checkout --track=inherit -b feature main`, then branch "feature" will track "origin/main". Thus, `git status` will show us how far ahead/behind we are from origin, and `git pull` will pull from origin. This is particularly useful when creating branches across many submodules, such as with `git submodule foreach ...` (or if running with a patch such as [1], which we use at $job), as it avoids having to manually set tracking info for each submodule. Since we've added an argument to "--track", also add "--track=direct" as another way to explicitly get the original "--track" behavior ("--track" without an argument still works as well). Finally, teach branch.autoSetupMerge a new "inherit" option. When this is set, "--track=inherit" becomes the default behavior.

2021-12-20branch: accept multiple upstream branches for trackingJosh Steadmon2-43/+106
Add a new static variant of install_branch_config() that accepts multiple remote branch names for tracking. This will be used in an upcoming commit that enables inheriting the tracking configuration from a parent branch. Currently, all callers of install_branch_config() pass only a single remote. Make install_branch_config() a small wrapper around install_branch_config_multiple_remotes() so that existing callers do not need to be changed.

2021-12-20merge: allow to pretend a merge is made into a different branchJunio C Hamano7-5/+67
When a series of patches for a topic-B depends on having topic-A, the workflow to prepare the topic-B branch would look like this: $ git checkout -b topic-B main $ git merge --no-ff --no-edit topic-A $ git am <mbox-for-topic-B When topic-A gets updated, recreating the first merge and rebasing the rest of the topic-B, all on detached HEAD, is a useful technique. After updating topic-A with its new round of patches: $ git checkout topic-B $ prev=$(git rev-parse 'HEAD^{/^Merge branch .topic-A. into}') $ git checkout --detach $prev^1 $ git merge --no-ff --no-edit topic-A $ git rebase --onto HEAD $prev @{-1}^0 $ git checkout -B @{-1} This will (0) check out the current topic-B. (1) find the previous merge of topic-A into topic-B. (2) detach the HEAD to the parent of the previous merge. (3) merge the updated topic-A to it. (4) reapply the patches to rebuild the rest of topic-B. (5) update topic-B with the result. without contaminating the reflog of topic-B too much. topic-B@{1} is the "logically previous" state before topic-A got updated, for example. At (4), comparison (e.g. range-diff) between HEAD and @{-1} is a meaningful way to sanity check the result, and the same can be done at (5) by comparing topic-B and topic-B@{1}. But there is one glitch. The merge into the detached HEAD done in the step (3) above gives us "Merge branch 'topic-A' into HEAD", and does not say "into topic-B". Teach the "--into-name=<branch>" option to "git merge" and its underlying "git fmt-merge-message", to pretend as if we were merging into <branch>, no matter what branch we are actually merging into, when they prepare the merge message. The pretend name honors the usual "into <target>" suppression mechanism, which can be seen in the tests added here. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-12-20git-p4: show progress as an integerJoel Holdsworth1-1/+2
When importing files from Perforce, git-p4 periodically logs the progress of file transfers as a percentage. However, the value is printed as a float with an excessive number of decimal places. For example a typical update might contain the following message: Importing revision 12345 (26.199617677553135%) This patch simply rounds the value down to the nearest integer percentage value, greatly improving readability.

2021-12-20git-p4: print size values in appropriate unitsJoel Holdsworth1-5/+19
The git-p4 script reports file sizes in various log messages. Previously, in each case the script would print them as the number of bytes divided by 1048576 i.e. the size in mebibytes, rounded down to an integer. This resulted in small files being described as having a size of "0 MB". This patch replaces the existing behaviour with a new helper function: format_size_human_readable, which takes a number of bytes (or any other quantity), and computes the appropriate prefix to use: none, Ki, Mi, Gi, Ti, Pi, Ei, Zi, Yi. For example, a size of 123456 will now be printed as "120.6 KiB" greatly improving the readability of the log output. Large valued prefixes such as pebi, exbi, zebi and yobi are included for completeness, though they not expected to appear in any real-world Perforce repository!

2021-12-20git-apply: skip threeway in add / rename casesJerry Zhang2-1/+21
Certain invocations of "git apply --3way" will attempt threeway and fail due to missing objects, even though git is able to fall back on apply_fragments and apply the patch successfully with a return value of 0. To fix, return early from try_threeway() in the following cases: - When the patch is a rename and no lines have changed. In this case, "git diff" doesn't record the blob info, so 3way is neither possible nor necessary. - When the patch is an addition and there is no add/add conflict, i.e. direct_to_threeway is false. In this case, threeway will fail since the preimage is not in cache, but isn't necessary anyway since there is no conflict. This fixes a few unecessary error messages when applying these kinds of patches with --3way. It also fixes a reported issue where applying a concatenation of several git produced patches will fail when those patches involve a deletion followed by creation of the same file. Add a test for this case too. (test provided by <i@zenithal.me>) Signed-off-by: Jerry Zhang <jerry@skydio.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-12-20repack: make '--quiet' disable progressDerrick Stolee3-4/+14
While testing some ideas in 'git repack', I ran it with '--quiet' and discovered that some progress output was still shown. Specifically, the output for writing the multi-pack-index showed the progress. The 'show_progress' variable in cmd_repack() is initialized with isatty(2) and is not modified at all by the '--quiet' flag. The '--quiet' flag modifies the po_args.quiet option which is translated into a '--quiet' flag for the 'git pack-objects' child process. However, 'show_progress' is used to directly send progress information to the multi-pack-index writing logic which does not use a child process. The fix here is to modify 'show_progress' to be false if po_opts.quiet is true, and isatty(2) otherwise. This new expectation simplifies a later condition that checks both. Update the documentation to make it clear that '-q' will disable all progress in addition to ensuring the 'git pack-objects' child process will receive the flag. Use 'test_terminal' to check that this works to get around the isatty(2) check.

2021-12-20repack: respect kept objects with '--write-midx -b'Derrick Stolee3-1/+41
Historically, we needed a single packfile in order to have reachability bitmaps. This introduced logic that when 'git repack' had a '-b' option that we should stop sending the '--honor-pack-keep' option to the 'git pack-objects' child process, ensuring that we create a packfile containing all reachable objects. In the world of multi-pack-index bitmaps, we no longer need to repack all objects into a single pack to have valid bitmaps. Thus, we should continue sending the '--honor-pack-keep' flag to 'git pack-objects'. The fix is very simple: only disable the flag when writing bitmaps but also _not_ writing the multi-pack-index. This opens the door to new repacking strategies that might want to keep some historical set of objects in a stable pack-file while only repacking more recent objects. To test, create a new 'test_subcommand_inexact' helper that is more flexible than 'test_subcommand'. This allows us to look for the --honor-pack-keep flag without over-indexing on the exact set of arguments.

2021-12-17log: let --invert-grep only invert --grepRené Scharfe5-7/+42
The option --invert-grep is documented to filter out commits whose messages match the --grep filters. However, it also affects the header matches (--author, --committer), which is not intended. Move the handling of that option to grep.c, as only the code there can distinguish between matches in the header from those in the message body. If --invert-grep is given then enable extended expressions (not the regex type, we just need git grep's --not to work), negate the body patterns and check if any of them match by piggy-backing on the collect_hits mechanism of grep_source_1(). Collecting the matches in struct grep_opt is a bit iffy, but with "last_shown" we have a precedent for writing state information to that struct.

2021-12-16git-p4: resolve RCS keywords in bytes not utf-8Joel Holdsworth2-7/+23
RCS keywords are strings that are replaced with information from Perforce. Examples include $Date$, $Author$, $File$, $Change$ etc. Perforce resolves these by expanding them with their expanded values when files are synced, but Git's data model requires these expanded values to be converted back into their unexpanded form. Previously, git-p4.py would implement this behaviour through the use of regular expressions. However, the regular expression substitution was applied using decoded strings i.e. the content of incoming commit diffs was first decoded from bytes into UTF-8, processed with regular expressions, then converted back to bytes. Not only is this behaviour inefficient, but it is also a cause of a common issue caused by text files containing invalid UTF-8 data. For files created in Windows, CP1252 Smart Quote Characters (0x93 and 0x94) are seen fairly frequently. These codes are invalid in UTF-8, so if the script encountered any file containing them, on Python 2 the symbols will be corrupted, and on Python 3 the script will fail with an exception. This patch replaces this decoding/encoding with bytes object regular expressions, so that the substitution is performed directly upon the source data with no conversions. A test for smart quote handling has been added to the t9810-git-p4-rcs.sh test suite. Signed-off-by: Joel Holdsworth <jholdsworth@nvidia.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-12-16stash: don't show "git stash push" usage on bad "git stash" usageÆvar Arnfjörð Bjarmason2-0/+20
Change the usage message emitted by "git stash --invalid-option" to emit usage information for "git stash" in general, and not just for the "push" command. I.e. before: $ git stash --invalid-option error: unknown option `invalid-option' usage: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet] [-u|--include-untracked] [-a|--all] [-m|--message <message>] [--] [<pathspec>...]] [...] After: $ git stash --invalid-option error: unknown option `invalid-option' usage: git stash list [<options>] or: git stash show [<options>] [<stash>] or: git stash drop [-q|--quiet] [<stash>] or: git stash ( pop | apply ) [--index] [-q|--quiet] [<stash>] or: git stash branch <branchname> [<stash>] or: git stash clear or: git stash [push [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet] [-u|--include-untracked] [-a|--all] [-m|--message <message>] [--pathspec-from-file=<file> [--pathspec-file-nul]] [--] [<pathspec>...]] or: git stash save [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet] [-u|--include-untracked] [-a|--all] [<message>] [...] That we emitted the usage for just "push" in the case of the subcommand not being explicitly specified was an unintentional side-effect of how it was implemented. When it was converted to C in d553f538b8a (stash: convert push to builtin, 2019-02-25) the pattern of having per-subcommand usage information was rightly continued. The "git-stash.sh" shellscript did not have that, and always printed the equivalent of "git_stash_usage". But in doing so the case of push being implicit and explicit was conflated. A variable was added to track this in 8c3713cede7 (stash: eliminate crude option parsing, 2020-02-17), but it did not update the usage output accordingly. This still leaves e.g. "git stash push -h" emitting the "git_stash_usage" output, instead of "git_stash_push_usage". That should be fixed, but is a much deeper misbehavior in parse_options() not being aware of subcommands at all. I.e. in how PARSE_OPT_KEEP_UNKNOWN and PARSE_OPT_NO_INTERNAL_HELP combine in commands such as "git stash". Perhaps PARSE_OPT_KEEP_UNKNOWN should imply PARSE_OPT_NO_INTERNAL_HELP, or better yet parse_options() should be extended to fully handle these subcommand cases that we handle manually in "git stash", "git commit-graph", "git multi-pack-index" etc. All of those musings would be a much bigger change than this isolated fix though, so let's leave that for some other time.

2021-12-15upload-pack.c: increase output buffer sizeJacob Vosmaer1-5/+12
When serving a fetch, git upload-pack copies data from a git pack-objects stdout pipe to its stdout. This commit increases the size of the buffer used for that copying from 8192 to 65515, the maximum sideband-64k packet size. Previously, this buffer was allocated on the stack. Because the new buffer size is nearly 64KB, we switch this to a heap allocation. On GitLab.com we use GitLab's pack-objects cache which does writes of 65515 bytes. Because of the default 8KB buffer size, propagating these cache writes requires 8 pipe reads and 8 pipe writes from git-upload-pack, and 8 pipe reads from Gitaly (our Git RPC service). If we increase the size of the buffer to the maximum Git packet size, we need only 1 pipe read and 1 pipe write in git-upload-pack, and 1 pipe read in Gitaly to transfer the same amount of data. In benchmarks with a pure fetch and 100% cache hit rate workload we are seeing CPU utilization reductions of over 30%.

2021-12-15sparse-checkout: enable `set` to initialize sparse-checkout modeElijah Newren1-1/+26
The previously suggested workflow: git sparse-checkout init ... git sparse-checkout set ... Suffered from three problems: 1) It would delete nearly all files in the first step, then restore them in the second. That was poor performance and forced unnecessary rebuilds. 2) The two-step process resulted in two progress bars, which was suboptimal from a UI point of view for wrappers that invoked both of these commands but only exposed a single command to their end users. 3) With cone mode, the first step would delete nearly all ignored files everywhere, because everything was considered to be outside of the specified sparsity paths. (The user was not allowed to specify any sparsity paths in the `init` step.) Avoid these problems by teaching `set` to understand the extra parameters that `init` takes and performing any necessary initialization if not already in a sparse checkout.

However, we would like sparse_checkout_set() to do the same work that sparse_checkout_init() does if sparse checkouts are not already enabled. To facilitate this transition, give each mode their own copy of the function. This does not introduce any behavioral changes; that will come in a subsequent patch.

2021-12-15sparse-checkout: pass use_stdin as a parameter instead of as a globalElijah Newren1-12/+16
add_patterns_from_input() has relied on a global variable, set_opts.use_stdin, which has been used by both the `set` and `add` subcommands of sparse-checkout. Once we introduce an add_opts.use_stdin, the hardcoding of set_opts.use_stdin will be incorrect. Pass the value as function parameter instead to allow us to make subsequent changes.
