2016-02-22config: add '--show-origin' option to print the origin of a config valueLibravatar Lars Schneider1-0/+147
If config values are queried using 'git config' (e.g. via --get, --get-all, --get-regexp, or --list flag) then it is sometimes hard to find the configuration file where the values were defined. Teach 'git config' the '--show-origin' option to print the source configuration file for every printed value.

2015-08-10config: add '--name-only' option to list only variable namesLibravatar SZEDER Gábor1-0/+22
'git config' can only show values or name-value pairs, so if a shell script needs the names of set config variables it has to run 'git config --list' or '--get-regexp' and parse the output to separate config variable names from their values. However, such a parsing can't cope with multi-line values. Though 'git config' can produce null-terminated output for newline-safe parsing, that's of no use in such a case, becase shells can't cope with null characters. Even our own bash completion script suffers from these issues. Help the completion script, and shell scripts in general, by introducing the '--name-only' option to modify the output of '--list' and '--get-regexp' to list only the names of config variables, so they don't have to perform error-prone post processing to separate variable names from their values anymore.

Ordinarily, we would say "VAR=VAL command" to execute a tested command with environment variable(s) set only for that command. This however does not work if 'command' is a shell function (most notably 'test_must_fail'); the result of the assignment is retained and affects later commands. To avoid this, we used to assign and export environment variables and run such a test in a subshell, like so: ( VAR=VAL && export VAR && test_must_fail git command to be tested ) But with "env" utility, we should be able to say: test_must_fail env VAR=VAL git command to be tested which is much shorter and easier to read.

2013-09-09git-config: always treat --int as 64-bit internallyLibravatar Jeff King1-0/+7
When you run "git config --int", the maximum size of integer you get depends on how git was compiled, and what it considers to be an "int". This is almost useful, because your scripts calling "git config" will behave similarly to git internally. But relying on this is dubious; you have to actually know how git treats each value internally (e.g., int versus unsigned long), which is not documented and is subject to change. And even if you know it is "unsigned long", we do not have a git-config option to match that behavior. Furthermore, you may simply be asking git to store a value on your behalf (e.g., configuration for a hook). In that case, the relevant range check has nothing at all to do with git, but rather with whatever scripting tools you are using (and git has no way of knowing what the appropriate range is there). Not only is the range check useless, but it is actively harmful, as there is no way at all for scripts to look at config variables with large values. For instance, one cannot reliably get the value of pack.packSizeLimit via git-config. On an LP64 system, git happily uses a 64-bit "unsigned long" internally to represent the value, but the script cannot read any value over 2G. Ideally, the "--int" option would simply represent an arbitrarily large integer. For practical purposes, however, a 64-bit integer is large enough, and is much easier to implement (and if somebody overflows it, we will still notice the problem, and not simply return garbage).

If we try to parse an integer config argument and get a number outside of the representable range, we die with the cryptic message: "bad config value for '%s'". We can improve two things: 1. Show the value that produced the error (e.g., bad config value '3g' for 'foo.bar'). 2. Mention the reason the value was rejected (e.g., "invalid unit" versus "out of range"). A few tests need to be updated with the new output, but that should not be representative of real-world breakage, as scripts should not be depending on the exact text of our stderr output, which is subject to i18n anyway.

Using the same urlmatch_config_entry() infrastructure, add a new mode "--get-urlmatch" to the "git config" command, to learn values for the "virtual" two-level variables customized for the specific URL. git config [--<type>] --get-urlmatch <section>[.<key>] <url> With <section>.<key> fully specified, the configuration data for <section>.<urlpattern>.<key> for <urlpattern> that best matches the given <url> is sought (and if not found, <section>.<key> is used) and reported. For example, with this configuration: [http] sslVerify [http "https://weak.example.com"] cookieFile = /tmp/cookie.txt sslVerify = false You would get $ git config --bool --get-urlmatch http.sslVerify https://good.example.com true $ git config --bool --get-urlmatch http.sslVerify https://weak.example.com false With only <section> specified, you can get a list of all variables in the section with their values that apply to the given URL.

2013-03-29t1300: document some aesthetic failures of the config editorLibravatar Jeff King1-0/+35
The config-editing code used by "git config var value" is built around the regular config callback parser, whose only triggerable item is an actual key. As a result, it does not know anything about section headers, which can result in unnecessarily ugly output: 1. When we delete the last key in a section, we should be able to delete the section header. 2. When we add a key into a section, we should be able to reuse the same section header, even if that section did not have any keys in it already. Unfortunately, fixing these is not trivial with the current code. It would involve the config parser recording and passing back information on each item it finds, including headers, keys, and even comments (or even better, generating an actual in-memory parse-tree). Since these behaviors do not cause any functional problems (i.e., the resulting config parses as expected, it is just uglier than one would like), fixing them can wait until somebody feels like substantially refactoring the parsing code. In the meantime, let's document them as known issues with some tests. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-10-24git-config: do not complain about duplicate entriesLibravatar Jeff King1-2/+4
If git-config is asked for a single value, it will complain and exit with an error if it finds multiple instances of that value. This is unlike the usual internal config parsing, however, which will generally overwrite previous values, leaving only the final one. For example: [set a multivar] $ git config user.email one@example.com $ git config --add user.email two@example.com [use the internal parser to fetch it] $ git var GIT_AUTHOR_IDENT Your Name <two@example.com> ... [use git-config to fetch it] $ git config user.email one@example.com error: More than one value for the key user.email: two@example.com This overwriting behavior is critical for the regular parser, which starts with the lowest-priority file (e.g., /etc/gitconfig) and proceeds to the highest-priority file ($GIT_DIR/config). Overwriting yields the highest priority value at the end. Git-config solves this problem by implementing its own parsing. It goes from highest to lowest priorty, but does not proceed to the next file if it has seen a value. So in practice, this distinction never mattered much, because it only triggered for values in the same file. And there was not much point in doing that; the real value is in overwriting values from lower-priority files. However, this changed with the implementation of config include files. Now we might see an include overriding a value from the parent file, which is a sensible thing to do, but git-config will flag as a duplication. This patch drops the duplicate detection for git-config and switches to a pure-overwrite model (for the single case; --get-all can still be used if callers want to do something more fancy). As is shown by the modifications to the test suite, this is a user-visible change in behavior. An alternative would be to just change the include case, but this is much cleaner for a few reasons: 1. If you change the include case, then to what? If you just stop parsing includes after getting a value, then you will get a _different_ answer than the regular config parser (you'll get the first value instead of the last value). So you'd want to implement overwrite semantics anyway. 2. Even though it is a change in behavior for git-config, it is bringing us in line with what the internal parsers already do. 3. The file-order reimplementation is the only thing keeping us from sharing more code with the internal config parser, which will help keep differences to a minimum. Going under the assumption that the primary purpose of git-config is to behave identically to how git's internal parsing works, this change can be seen as a bug-fix.

2012-10-24t1300: style updatesLibravatar Jeff King1-123/+178
The t1300 test script is quite old, and does not use our modern techniques or styles. This patch updates it in the following ways: 1. Use test_cmp instead of cmp (to make failures easier to debug). 2. Use test_cmp instead of 'test $(command) = expected'. This makes failures much easier to debug, and also makes sure that $(command) exits appropriately. 3. Use test_must_fail (easier to read, and checks more rigorously for signal death). 4. Write tests with the usual style of: test_expect_success 'test name' ' test commands && ... ' rather than one-liners, or using backslash-continuation. This is purely a style fixup. There are still a few command happening outside of test_expect invocations, but they are all innoccuous system commands like "cat" and "cp". In an ideal world, each test would be self sufficient and all commands would happen inside test_expect, but it is not immediately obvious how the grouping should work (some of the commands impact the subsequent tests, and some of them are setting up and modifying state that many tests depend on). This patch just picks the low-hanging style fruit, and we can do more fixes on top later. Signed-off-by: Jeff King <peff@peff.net>

2012-02-17config: stop using config_exclusive_filenameLibravatar Jeff King1-0/+25
The git-config command sometimes operates on the default set of config files (either reading from all, or writing to repo config), and sometimes operates on a specific file. In the latter case, we set the magic global config_exclusive_filename, and the code in config.c does the right thing. Instead, let's have git-config use the "advanced" variants of config.c's functions which let it specify an individual filename (or NULL for the default). This makes the code a lot more obvious, and fixes two small bugs: 1. A relative path specified by GIT_CONFIG=foo will look in the wrong directory if we have to chdir as part of repository setup. We already handle this properly for "git config -f foo", but the GIT_CONFIG lookup used config_exclusive_filename directly. By dropping to a single magic variable, the GIT_CONFIG case now just works. 2. Calling "git config -f foo --edit" would not respect core.editor. This is because just before editing, we called git_config, which would respect the config_exclusive_filename setting, even though this particular git_config call was not about looking in the user's specified file, but rather about loading actual git config, just as any other git program would.

We should be able to ask for a config value both by its canonical all-lowercase name (as git does internally), as well as by random mixed-case (which will be canonicalized by git-config for us). Subsections are a tricky point, though. Since we have both [section "Foo"] and [section.Foo] you might want git-config to canonicalize the subsection or not, depending on which you are expecting. But there's no way to communicate this; git-config sees only the key, and doesn't know which type of section name will be in the config file. So it must leave the subsection intact, and it is up to the caller to provide a canonical version of the subsection if they want to match the latter form.

But the two odd things are: 1. We actually die on most errors in git_config_from_file. In fact, the only error we actually pass back up is if fopen() fails on the file. 2. Most callers of git_config do not check the error return at all, but will continue if git_config reports an error. When the code for "git -c core.foo=bar" was added, it dutifully passed errors up the call stack, only for them to be eventually ignored. This makes it inconsistent with the file-parsing code, which will die when it sees malformed config. And it's somewhat unsafe, because it means an error in parsing a typo like: git -c clean.requireforce=ture clean will continue the command, ignoring the config the user tried to give.

2011-06-22fix "git -c" parsing of values with equals signsLibravatar Jeff King1-0/+6
If you do something like: git -c core.foo="value with = in it" ... we would split your option on "=" into three fields and throw away the third one. With this patch we correctly take everything after the first "=" as the value (keys cannot have an equals sign in them, so the parsing is unambiguous).

* jk/maint-config-alias-fix: handle_options(): do not miscount how many arguments were used config: always parse GIT_CONFIG_PARAMETERS during git_config git_config: don't peek at global config_parameters config: make environment parsing routines static
2011-05-24handle_options(): do not miscount how many arguments were usedLibravatar Junio C Hamano1-1/+1
The handle_options() function advances the base of the argument array and returns the number of arguments it used. The caller in handle_alias() wants to reallocate the argv array it passes to this function, and attempts to do so by subtracting the returned value to compensate for the change handle_options() makes to the new_argv. But handle_options() did not correctly count when "-c <config=value>" is given, causing a wrong pointer to be passed to realloc(). Fix it by saving the original argv at the beginning of handle_options(), and return the difference between the final value of argv, which will relieve the places that move the array pointer from the additional burden of keeping track of "handled" counter.

2011-05-24config: always parse GIT_CONFIG_PARAMETERS during git_configLibravatar Jeff King1-0/+7
Previously we parsed GIT_CONFIG_PARAMETERS lazily into a linked list, and then checked that list during future invocations of git_config. However, that ignores the fact that the environment variable could change during our run (e.g., because we parse more "-c" as part of an alias). Instead, let's just re-parse the environment variable each time. It's generally not very big, and it's no more work than parsing the config files, anyway. As a bonus, we can ditch all of the linked list storage code entirely, making the code much simpler. The test unfortunately still does not pass because of an unrelated bug in handle_options.
