Merge branch 'ab/free-and-null'

2017-06-24T21:28:41Z

A common pattern to free a piece of memory and assign NULL to the pointer that used to point at it has been replaced with a new FREE_AND_NULL() macro. * ab/free-and-null: *.[ch] refactoring: make use of the FREE_AND_NULL() macro coccinelle: make use of the "expression" FREE_AND_NULL() rule coccinelle: add a rule to make "expression" code use FREE_AND_NULL() coccinelle: make use of the "type" FREE_AND_NULL() rule coccinelle: add a rule to make "type" code use FREE_AND_NULL() git-compat-util: add a FREE_AND_NULL() wrapper around free(ptr); ptr = NULL

Merge branch 'bw/config-h'

2017-06-24T21:28:41Z

Fix configuration codepath to pay proper attention to commondir that is used in multi-worktree situation, and isolate config API into its own header file. * bw/config-h: config: don't implicitly use gitdir or commondir config: respect commondir setup: teach discover_git_directory to respect the commondir config: don't include config.h by default config: remove git_config_iter config: create config.h

Merge branch 'js/alias-early-config'

2017-06-24T21:28:40Z

The code to pick up and execute command alias definition from the configuration used to switch to the top of the working tree and then come back when the expanded alias was executed, which was unnecessarilyl complex. Attempt to simplify the logic by using the early-config mechanism that does not chdir around. * js/alias-early-config: alias: use the early config machinery to expand aliases t7006: demonstrate a problem with aliases in subdirectories t1308: relax the test verifying that empty alias values are disallowed help: use early config when autocorrecting aliases config: report correct line number upon error discover_git_directory(): avoid setting invalid git_dir

auto-correct: tweak phrasing

2017-06-21T20:53:37Z

When help.autoCorrect is enabled, an invalid git command prints a warning and a continuation message, which differs depending on whether or not the value of help.autoCorrect is positive or negative. With help.autoCorrect = 15: WARNING: You called a Git command named 'lgo', which does not exist. Continuing under the assumption that you meant 'log' in 1.5 seconds automatically... With help.autoCorrect < 0: WARNING: You called a Git command named 'lgo', which does not exist. Continuing under the assumption that you meant 'log' The continuation message's phrasing is awkward. This commit cleans it up. As a bonus, we now use full-sentence strings which make translation easier. With help.autoCorrect = 15: WARNING: You called a Git command named 'lgo', which does not exist. Continuing in 1.5 seconds, assuming that you meant 'log'. With help.autoCorrect < 0: WARNING: You called a Git command named 'lgo', which does not exist. Continuing under the assumption that you meant 'log'. Signed-off-by: Marc Branchaud Signed-off-by: Junio C Hamano

Merge branch 'jk/consistent-h'

2017-06-19T19:38:45Z

"git $cmd -h" for builtin commands calls the implementation of the command (i.e. cmd_$cmd() function) without doing any repository set-up, and the commands that expect RUN_SETUP is done by the Git potty needs to be prepared to show the help text without barfing. * jk/consistent-h: t0012: test "-h" with builtins git: add hidden --list-builtins option version: convert to parse-options diff- and log- family: handle "git cmd -h" early submodule--helper: show usage for "-h" remote-{ext,fd}: print usage message on invalid arguments upload-archive: handle "-h" option early credential: handle invalid arguments earlier

*.[ch] refactoring: make use of the FREE_AND_NULL() macro

2017-06-16T19:44:09Z

Replace occurrences of `free(ptr); ptr = NULL` which weren't caught by the coccinelle rule. These fall into two categories: - free/NULL assignments one after the other which coccinelle all put on one line, which is functionally equivalent code, but very ugly. - manually spotted occurrences where the NULL assignment isn't right after the free() call.

config: don't include config.h by default

2017-06-15T19:56:22Z

Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano

help: use early config when autocorrecting aliases

2017-06-15T19:31:43Z

Git has this feature which suggests similar commands (including aliases) in case the user specified an unknown command. This feature currently relies on a side effect of the way we expand aliases right now: when a command is not a builtin, we use the regular config machinery (meaning: discovering the .git/ directory and initializing global state such as the config cache) to see whether the command refers to an alias. However, we will change the way aliases are expanded in the next commits, to use the early config instead. That means that the autocorrect feature can no longer discover the available aliases by looking at the config cache (because it has not yet been initialized). So let's just use the early config machinery instead. This is slightly less performant than the previous way, as the early config is used *twice*: once to see whether the command refers to an alias, and then to see what aliases are most similar. However, this is hardly a performance-critical code path, so performance is less important here. Signed-off-by: Johannes Schindelin Reviewed-by: Jeff King Signed-off-by: Junio C Hamano

version: convert to parse-options

2017-06-05T02:43:33Z

The "git version" command didn't traditionally accept any options, and in fact ignores any you give it. When we added simple option parsing for "--build-options" in 6b9c38e14, we didn't improve this; we just loop over the arguments and pick out the one we recognize. Instead, let's move to a real parsing loop, complain about nonsense options, and recognize conventions like "-h". Signed-off-by: Jeff King Signed-off-by: Junio C Hamano
