* Introduce `git_sysdir_expand_global_file`Edward Thomson2017-03-231-0/+11
| | | | | | | Provide a mechanism for callers to expand the full path of a file in the global configuration directory (that is to say, the home directory) even if the file doesn't necessarily exist. This lets callers use their own logic for building paths separate from handling file existence.
* giterr_set: consistent error messagesEdward Thomson2016-12-291-2/+2
| | | | | | | | Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
* sysdir: don't guess the paths again when $PATH is specifiedcmn/sysdir-no-reguessCarlos Martín Nieto2016-12-181-1/+1
| | | | We should replace it with whatever the user set, not start again.
* sysdir: use the standard `init` patternethomson/paths_initEdward Thomson2016-08-041-47/+41
| | | | | | | | | | | | | | Don't try to determine when sysdirs are uninitialized. Instead, simply initialize them all at `git_libgit2_init` time and never try to reinitialize, except when consumers explicitly call `git_sysdir_set`. Looking at the buffer length is especially problematic, since there may no appropriate path for that value. (For example, the Windows-specific programdata directory has no value on non-Windows machines.) Previously we would continually trying to re-lookup these values, which could get racy if two different threads are each calling `git_sysdir_get` and trying to lookup / clear the value simultaneously.
* config: add a ProgramData levelcmn/programdata-configCarlos Martín Nieto2015-10-211-1/+18
| | | | | This is where portable git stores the global configuration which we can use to adhere to it even though git isn't quite installed on the system.
* git__getenv: utf-8 aware env readerEdward Thomson2015-07-021-8/+22
| | | | | | Introduce `git__getenv` which is a UTF-8 aware `getenv` everywhere. Make `cl_getenv` use this to keep consistent memory handling around return values (free everywhere, as opposed to only some platforms).
* Fix the issues in git__on_shutdownAnurag Gupta2014-05-061-0/+2

* Improve handling of fake home directoryRussell Belfer2014-05-021-5/+11
| | | | | | | | | | There are a few tests that set up a fake home directory and a fake GLOBAL search path so that we can test things in global ignore or attribute or config files. This cleans up that code to work more robustly even if there is a test failure. This also fixes some valgrind warnings where scanning search paths for separators could end up doing a little bit of sketchy data access when coming to the end of search list.
* sysdir: free the path if we cannot find the fileCarlos Martín Nieto2014-04-211-1/+1
| | | | | Returning an error cleared the buf, but this operation does not free the memory associated with it. Use git_buf_free() instead.
* Move system directory cache out of utilsEdward Thomson2014-02-241-0/+244
