2020-02-10submodule-config: add subomdule config scopeLibravatar Matthew Rogers1-0/+1
Before the changes to teach git_config_source to remember scope information submodule-config.c never needed to consider the question of config scope. Even though zeroing out git_config_source is still correct and preserved the previous behavior of setting the scope to CONFIG_SCOPE_UNKNOWN, it's better to be explicit about such situations by explicitly setting the scope. As none of the current config_scope enumerations make sense we create CONFIG_SCOPE_SUBMODULE to describe the situation.

2020-02-10config: teach git_config_source to remember its scopeLibravatar Matthew Rogers1-10/+11
There are many situations where the scope of a config command is known beforehand, such as passing of '--local', '--file', etc. to an invocation of git config. However, this information is lost when moving from builtin/config.c to /config.c. This historically hasn't been a big deal, but to prepare for the upcoming --show-scope option we teach git_config_source to keep track of the source and the config machinery to use that information to set current_parsing_scope appropriately.

2020-02-10config: clarify meaning of command line scopingLibravatar Matthew Rogers1-1/+1
CONFIG_SCOPE_CMDLINE is generally used in the code to refer to config values passed in via the -c option. Options passed in using this mechanism share similar scoping characteristics with the --file and --blob options of the 'config' command, namely that they are only in use for that single invocation of git, and that they supersede the normal system/global/local hierarchy. This patch introduces CONFIG_SCOPE_COMMAND to reflect this new idea, which also makes CONFIG_SCOPE_CMDLINE redundant.

2020-02-10config: split repo scope to local and worktreeLibravatar Matthew Rogers1-1/+2
Previously when iterating through git config variables, worktree config and local config were both considered "CONFIG_SCOPE_REPO". This was never a problem before as no one had needed to differentiate between the two cases, but future functionality may care whether or not the config options come from a worktree or from the repository's actual local config file. For example, the planned feature to add a '--show-scope' to config to allow a user to see which scope listed config options come from would confuse users if it just printed 'repo' rather than 'local' or 'worktree' as the documentation would lead them to expect. As well as the additional benefit of making the implementation look more like how the documentation describes the interface. To accomplish this we split out what was previously considered repo scope to be local and worktree. The clients of 'current_config_scope()' who cared about CONFIG_SCOPE_REPO are also modified to similarly care about CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

2020-02-10config: make scope_name non-static and rename itLibravatar Matthew Rogers1-0/+1
To prepare for the upcoming --show-scope option, we require the ability to convert a config_scope enum to a string. As this was originally implemented as a static function 'scope_name()' in t/helper/test-config.c, we expose it via config.h and give it a less ambiguous name 'config_scope_name()' Signed-off-by: Matthew Rogers <mattr94@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-05-05*.[ch]: remove extern from function declarations using sedLibravatar Denton Liu1-1/+1
There has been a push to remove extern from function declarations. Finish the job by removing all instances of "extern" for function declarations in headers using sed. This was done by running the following on my system with sed 4.2.2: $ git ls-files \*.{c,h} | grep -v ^compat/ | xargs sed -i'' -e 's/^\(\s*\)extern \([^(]*([^*]\)/\1\2/' Files under `compat/` are intentionally excluded as some are directly copied from external sources and we should avoid churning them as much as possible. Then, leftover instances of extern were found by running $ git grep -w -C3 extern \*.{c,h} and manually checking the output. No other instances were found. Note that the regex used specifically excludes function variables which _should_ be left as extern. Not the most elegant way to do it but it gets the job done.

2018-11-21index: make index.threads=true enable ieot and eoieLibravatar Jonathan Nieder1-1/+1
If a user explicitly sets [index] threads = true to read the index using multiple threads, ensure that index writes include the offset table by default to make that possible. This ensures that the user's intent of turning on threading is respected. In other words, permit the following configurations: - index.threads and index.recordOffsetTable unspecified: do not write the offset table yet (to avoid alarming the user with "ignoring IEOT extension" messages when an older version of Git accesses the repository) but do make use of multiple threads to read the index if the supporting offset table is present. This can also be requested explicitly by setting index.threads=true, 0, or >1 and index.recordOffsetTable=false. - index.threads=false or 1: do not write the offset table, and do not make use of the offset table. One can set index.recordOffsetTable=false as well, to be more explicit. - index.threads=true, 0, or >1 and index.recordOffsetTable unspecified: write the offset table and make use of threads at read time. This can also be requested by setting index.threads=true, 0, >1, or unspecified and index.recordOffsetTable=true. Fortunately the complication is temporary: once most Git installations have upgraded to a version with support for the IEOT and EOIE extensions, we can flip the defaults for index.recordEndOfIndexEntries and index.recordOffsetTable to true and eliminate the settings.

The config code has a die_on_error flag, which lets us emit an error() instead of dying when we see a bogus config file. But there's no way for a caller of the config code to set this: it's auto-set based on whether we're reading a file or a blob. Instead, let's add it to the config_options struct.

2018-06-11http-backend: respect CONTENT_LENGTH as specified by rfc3875Libravatar Max Kirillov1-0/+1
http-backend reads whole input until EOF. However, the RFC 3875 specifies that a script must read only as many bytes as specified by CONTENT_LENGTH environment variable. Web server may exercise the specification by not closing the script's standard input after writing content. In that case http-backend would hang waiting for the input. The issue is known to happen with IIS/Windows, for example. Make http-backend read only CONTENT_LENGTH bytes, if it's defined, rather than the whole input until EOF. If the variable is not defined, keep older behavior of reading until EOF because it is used to support chunked transfer-encoding. This commit only fixes buffered input, whcih reads whole body before processign it. Non-buffered input is going to be fixed in subsequent commit.

detecting new or changed files. When the index is read from disk, the fsmonitor index extension is used to flag the last known potentially dirty index entries. The registered core.fsmonitor command is called with the time the index was last updated and returns the list of files changed since that time. This list is used to flag any additional dirty cache entries and untracked cache directories. We can then use this valid state to speed up preload_index(), ie_match_stat(), and refresh_cache_ent() as they do not need to lstat() files to detect potential changes for those entries marked CE_FSMONITOR_VALID. In addition, if the untracked cache is turned on valid_cached_dir() can skip checking directories for new or changed files as fsmonitor will invalidate the cache only for those directories that have been identified as having potential changes. To keep the CE_FSMONITOR_VALID state accurate during git operations; when git updates a cache entry to match the current state on disk, it will now set the CE_FSMONITOR_VALID bit. Inversely, anytime git changes a cache entry, the CE_FSMONITOR_VALID bit is cleared and the corresponding untracked cache directory is marked invalid.

These two configuration variables are described in the documentation to take an expiry period expressed in the number of days: gc.rerereResolved:: Records of conflicted merge you resolved earlier are kept for this many days when 'git rerere gc' is run. The default is 60 days. gc.rerereUnresolved:: Records of conflicted merge you have not resolved are kept for this many days when 'git rerere gc' is run. The default is 15 days. There is no strong reason not to allow a more general "approxidate" expiry specification, e.g. "5.days.ago", or "never". Rename the config_get_expiry() helper introduced in the previous step to git_config_get_expiry_in_days() and move it to a more generic place, config.c, and use date.c::parse_expiry_date() to do so. Give it an ability to allow the caller to tell among three cases (i.e. there is no "gc.rerereResolved" config, there is and it is correctly parsed into the *expiry variable, and there was an error in parsing the given value). The current caller can work correctly without using the return value, though. In the future, we may find other variables that only allow an integer that specifies "this many days" or other unit of time, and when it happens we may need to drop "_days" suffix from the name of the function and instead pass the "scale" value as another parameter. But this will do for now. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-06-23config: read config from a repository objectLibravatar Brandon Williams1-0/+24
Teach the config machinery to read config information from a repository object. This involves storing a 'struct config_set' inside the repository object and adding a number of functions (repo_config*) to be able to query a repository's config. The current config API enables lazy-loading of the config. This means that when 'git_config_get_int()' is called, if the_config_set hasn't been populated yet, then it will be populated and properly initialized by reading the necessary config files (system wide .gitconfig, user's home .gitconfig, and the repository's config). To maintain this paradigm, the new API to read from a repository object's config will also perform this lazy-initialization. Since both APIs (git_config_get* and repo_config_get*) have the same semantics we can migrate the default config to be stored within 'the_repository' and just have the 'git_config_get*' family of functions redirect to the 'repo_config_get*' functions.

'git_config_with_options()' takes a 'config_options' struct which contains feilds for 'git_dir' and 'commondir'. If those feilds happen to be NULL the config machinery falls back to querying global repository state. Let's change this and instead use these fields in the 'config_options' struct explicilty all the time. Since the API is slightly changing to require these two fields to be set if callers want the config machinery to load the repository's config, let's change the name to 'config_with_optison()'. This allows the config machinery to not implicitly rely on any global repository state. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-06-15config: respect commondirLibravatar Brandon Williams1-0/+1
Worktrees present an interesting problem when it comes to the config. Historically we could assume that the per-repository config lives at 'gitdir/config', but since worktrees were introduced this isn't the case anymore. There is currently no way to specify per-worktree configuration, and as such the repository config is shared with all worktrees and is located at 'commondir/config'. Many users of the config machinery correctly set 'config_options.git_dir' with the repository's commondir, allowing the config to be properly loaded when operating in a worktree. But other's, like 'read_early_config()', set 'config_options.git_dir' with the repository's gitdir which can be incorrect when using worktrees. To fix this issue, and to make things less ambiguous, lets add a 'commondir' field to the 'config_options' struct and have all callers properly set both the 'git_dir' and 'commondir' fields so that the config machinery is able to properly find the repository's config.

Since there is no implementation of the function 'git_config_iter', let's stop exporting it and remove the prototype from config.h. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-06-15config: create config.hLibravatar Brandon Williams1-0/+194
Move all config related declarations from cache.h to a new config.h header file. This makes cache.h smaller and allows for the opportunity in a following patch to only include config.h when needed. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
