2019-10-25t5510-fetch.sh: demonstrate fetch.writeCommitGraph bugLibravatar Derrick Stolee1-0/+16
While dogfooding, Johannes found a bug in the fetch.writeCommitGraph config behavior. His example initially happened during a clone with --recurse-submodules, we found that this happens with the first fetch after cloning a repository that contains a submodule: $ git clone <url> test $ cd test $ git -c fetch.writeCommitGraph=true fetch origin Computing commit graph generation numbers: 100% (12/12), done. BUG: commit-graph.c:886: missing parent <hash1> for commit <hash2> Aborted (core dumped) In the repo I had cloned, there were really 60 commits to scan, but only 12 were in the list to write when calling compute_generation_numbers(). A commit in the list expects to see a parent, but that parent is not in the list. A follow-up will fix the bug, but first we create a test that demonstrates the problem. This test must be careful about an existing commit-graph file, since GIT_TEST_COMMIT_GRAPH=1 will cause the repo we are cloning to already have one. This then prevents the incremtnal commit-graph write during the first 'git fetch'.

2019-09-03fetch: add fetch.writeCommitGraph config settingLibravatar Derrick Stolee6-0/+51
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. For additional use, adjust the default to be true when feature.experimental is enabled. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-08-13repo-settings: create feature.experimental settingLibravatar Derrick Stolee9-45/+60
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 Stolee6-7/+51
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.

2019-08-13repo-settings: parse core.untrackedCacheLibravatar Derrick Stolee5-36/+40
The core.untrackedCache config setting is slightly complicated, so clarify its use and centralize its parsing into the repo settings. The default value is "keep" (returned as -1), which persists the untracked cache if it exists. If the value is set as "false" (returned as 0), then remove the untracked cache if it exists. If the value is set as "true" (returned as 1), then write the untracked cache and persist it. Instead of relying on magic values of -1, 0, and 1, split these options into an enum. This allows the use of "-1" as a default value. After parsing the config options, if the value is unset we can initialize it to UNTRACKED_CACHE_KEEP.

2019-08-13commit-graph: turn on commit-graph by defaultLibravatar Derrick Stolee7-6/+12
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.

2019-08-13t6501: use 'git gc' in quiet modeLibravatar Derrick Stolee1-3/+3
t6501-freshen-objects.sh sends the standard error from 'git gc' to a file and verifies that it is empty. This is intended as a way to ensure no warnings are written during the operation. However, as the commit-graph is added as a step to 'git gc', its progress will appear in the output. Pass the '-q' argument to avoid a failing test case when progress is written.

2019-08-13repo-settings: consolidate some config settingsLibravatar Derrick Stolee7-19/+58
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.

2019-07-10ref-filter: fix memory leak in `free_array_item()`Libravatar Martin Ågren1-5/+9
We treat the `value` pointer as a pointer to a struct and free its `s` field. But `value` is in fact an array of structs. As a result, we only free the first `s` out of `used_atom_cnt`-many and leak the rest. Make sure we free all items in `value`. In the caller, `ref_array_clear()`, this means we need to be careful not to zero `used_atom_cnt` until after we've called `free_array_item()`. We could move just a single line, but let's keep related things close together instead, by first handling `array`, then `used_atom`.
