* config: don't include config.h by defaultBrandon Williams2017-06-15
| | | | | | | | 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 <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* prompt.c: remove git_getpass() nobody usesJunio C Hamano2015-01-15
| | | | | | | | | | | This was whittled down to a compatibility wrapper around the more flexible git_prompt() in 1cb0134f (refactor git_getpass into generic prompt function, 2011-12-10), waiting for the final callers to go away. That happened in 791643a8 (imap-send: use git-credential, 2014-04-28) when imap-send learned to use the credential interface.

* Merge branch 'jk/credential-quit'Junio C Hamano2014-12-22
|\ | | | | | | | | | | | | | | | | | | | | | | | | Credential helpers are asked in turn until one of them give positive response, which is cumbersome to turn off when you need to run Git in an automated setting. The credential helper interface learned to allow a helper to say "stop, don't ask other helpers." Also GIT_TERMINAL_PROMPT environment can be set to false to disable our built-in prompt mechanism for passwords. * jk/credential-quit: prompt: respect GIT_TERMINAL_PROMPT to disable terminal prompts credential: let helpers tell us to quit
| * prompt: respect GIT_TERMINAL_PROMPT to disable terminal promptsJeff King2014-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you run git as part of an automated system, you might prefer git to die rather than try to issue a prompt on the terminal (because there would be nobody to see it and respond, and the process would hang forever). This usually works out of the box because getpass() (and our more featureful replacements) will fail when there is no tty, but this does not cover all cases. For example, a batch system run via ssh might have a tty, even when the user does not expect it. Let's provide an environment variable the user can set to avoid even trying to touch the tty at all.

* | run-command: introduce CHILD_PROCESS_INITRené Scharfe2014-08-20
|/ | | | | | | | | | | | Most struct child_process variables are cleared using memset first after declaration. Provide a macro, CHILD_PROCESS_INIT, that can be used to initialize them statically instead. That's shorter, doesn't require a function call and is slightly more readable (especially given that we already have STRBUF_INIT, ARGV_ARRAY_INIT etc.).

* Revert "prompt: clean up strbuf usage"Jeff King2014-01-02
| | | | | | | | | | | | | | | | | | | This reverts commit 31b49d9b653803e7c7fd18b21c8bdd86e3421668. That commit taught do_askpass to hand ownership of our buffer back to the caller rather than simply return a pointer into our internal strbuf. What it failed to notice, though, was that our internal strbuf is static, because we are trying to emulate the getpass() interface. By handing off ownership, we created a memory leak that cannot be solved. Sometimes git_prompt returns a static buffer from getpass() (or our smarter git_terminal_prompt wrapper), and sometimes it returns an allocated string from do_askpass.

* prompt: fall back to terminal if askpass failsJeff King2012-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current askpass code simply dies if calling an askpass helper fails. Worse, in some failure modes it doesn't even print an error (if start_command fails, then it prints its own error; if reading fails, we print an error; but if the command exits non-zero, finish_command fails and we print nothing!). Let's be more kind to the user by printing an error message when askpass doesn't work out, and then falling back to the terminal (which also may fail, of course, but we die already there with a nice message). While we're at it, let's clean up the existing error messages a bit. Now that our prompts are very long and contain quotes and colons themselves, our error messages are hard to read. So the new failure modes look like: [before, with a terminal] $ GIT_ASKPASS=false git push $ echo $? 128 [before, with no terminal, and we must give up] $ setsid git push fatal: could not read 'Password for 'https://peff@github.com': ': No such device or address [after, with a terminal] $ GIT_ASKPASS=false git push error: unable to read askpass response from 'false' Password for 'https://peff@github.com': [after, with no terminal, and we must give up] $ GIT_ASKPASS=false setsid git push error: unable to read askpass response from 'false' fatal: could not read Password for 'https://peff@github.com': No such device or address Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* prompt: clean up strbuf usageJeff King2012-02-03
| | | | | | | | | | | | The do_askpass function inherited a few bad habits from the original git_getpass. One, there's no need to strbuf_reset a buffer which was just initialized. And two, it's a good habit to use strbuf_detach to claim ownership of a buffer's string (even though in this case the owning buffer goes out of scope, so it's effectively the same thing).

* prompt: use git_terminal_promptJeff King2011-12-12
| | | | | | | | | | | | Our custom implementation of git_terminal_prompt has many advantages over regular getpass(), as described in the prior commit. This also lets us implement a PROMPT_ECHO flag for callers who want it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* refactor git_getpass into generic prompt functionJeff King2011-12-12
| | | | | | | | | This will allow callers to specify more options (e.g., leaving echo on). The original git_getpass becomes a slim wrapper around the new function. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* move git_getpass to its own source fileJeff King2011-12-12
This is currently in connect.c, but really has nothing to do with the git protocol itself. Let's make a new source file all about prompting the user, which will make it cleaner to refactor. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
