2017-12-22config.txt: document behavior of backslashes in subsectionsLibravatar Dave Borowitz1-5/+7
Unrecognized escape sequences are invalid in values: $ git config -f - --list <<EOF [foo] bar = "\t\\\y\"\u" EOF fatal: bad config line 2 in standard input But in subsection names, the backslash is simply dropped if the following character does not produce a recognized escape sequence: $ git config -f - --list <<EOF [foo "\t\\\y\"\u"] bar = baz EOF foo.t\y"u.bar=baz Although it would be nice for subsection names and values to have consistent behavior, changing the behavior for subsection names is a nonstarter since it would cause existing, valid config files to suddenly be interpreted differently.

2017-12-07launch_editor(): indicate that Git waits for user inputLibravatar Lars Schneider1-0/+3
When a graphical GIT_EDITOR is spawned by a Git command that opens and waits for user input (e.g. "git rebase -i"), then the editor window might be obscured by other windows. The user might be left staring at the original Git terminal window without even realizing that s/he needs to interact with another window before Git can proceed. To this user Git appears hanging. Print a message that Git is waiting for editor input in the original terminal and get rid of it when the editor returns, if the terminal supports erasing the last line. Also, make sure that our message is terminated with a whitespace so that any message the editor may show upon starting up will be kept separate from our message. Power users might not want to see this message or their editor might already print such a message (e.g. emacsclient). Allow these users to suppress the message by disabling the "advice.waitingForEditor" config. The standard advise() function is not used here as it would always add a newline which would make deleting the message harder.

2017-11-21ssh: 'auto' variant to select between 'ssh' and 'simple'Libravatar Jonathan Nieder1-10/+16
Android's "repo" tool is a tool for managing a large codebase consisting of multiple smaller repositories, similar to Git's submodule feature. Starting with Git 94b8ae5a (ssh: introduce a 'simple' ssh variant, 2017-10-16), users noticed that it stopped handling the port in ssh:// URLs. The cause: when it encounters ssh:// URLs, repo pre-connects to the server and sets GIT_SSH to a helper ".repo/repo/git_ssh" that reuses that connection. Before 94b8ae5a, the helper was assumed to support OpenSSH options for lack of a better guess and got passed a -p option to set the port. After that patch, it uses the new default of a simple helper that does not accept an option to set the port. The next release of "repo" will set GIT_SSH_VARIANT to "ssh" to avoid that. But users of old versions and of other similar GIT_SSH implementations would not get the benefit of that fix. So update the default to use OpenSSH options again, with a twist. As observed in 94b8ae5a, we cannot assume that $GIT_SSH always handles OpenSSH options: common helpers such as travis-ci's dpl[*] are configured using GIT_SSH and do not accept OpenSSH options. So make the default a new variant "auto", with the following behavior: 1. First, check for a recognized basename, like today. 2. If the basename is not recognized, check whether $GIT_SSH supports OpenSSH options by running $GIT_SSH -G <options> <host> This returns status 0 and prints configuration in OpenSSH if it recognizes all <options> and returns status 255 if it encounters an unrecognized option. A wrapper script like exec ssh -- "$@" would fail with ssh: Could not resolve hostname -g: Name or service not known , correctly reflecting that it does not support OpenSSH options. The command is run with stdin, stdout, and stderr redirected to /dev/null so even a command that expects a terminal would exit immediately. 3. Based on the result from step (2), behave like "ssh" (if it succeeded) or "simple" (if it failed). This way, the default ssh variant for unrecognized commands can handle both the repo and dpl cases as intended. This autodetection has been running on Google workstations since 2017-10-23 with no reported negative effects.

2017-10-17Revert "color: make "always" the same as "auto" in config"Libravatar Jeff King1-17/+18
This reverts commit 6be4595edb8e5b616c6e8b9fbc78b0f831fa2a87. That commit weakened the "always" setting of color config so that it acted as "auto". This was meant to solve regressions in v2.14.2 in which setting "color.ui=always" in the on-disk config broke scripts like add--interactive, because the plumbing diff commands began to generate color output. This was due to 136c8c8b8f (color: check color.ui in git_default_config(), 2017-07-13), which was in turn trying to fix issues caused by 4c7f1819b3 (make color.ui default to 'auto', 2013-06-10). But in weakening "always", we created even more problems, as people expect to be able to use "git -c color.ui=always" to force color (especially because some commands don't have their own --color flag). We can fix that by special-casing the command-line "-c", but now things are getting pretty confusing. Instead of piling hacks upon hacks, let's start peeling off the hacks. The first step is dropping the weakening of "always", which this revert does. Note that we could actually revert the whole series merged in by da15b78e52642bd45fd5513ab0000fdf2e58a6f4. Most of that series consists of preparations to the tests to handle the weakening of "-c color.ui=always". But it's worth keeping for a few reasons: - there are some other preparatory cleanups, like e433749d86 (test-terminal: set TERM=vt100, 2017-10-03) - it adds "--color" options more consistently in 0c88bf5050 (provide --color option for all ref-filter users, 2017-10-03) - some of the cases dropping "-c" end up being more robust and realistic tests, as in 01c94e9001 (t7508: use test_terminal for color output, 2017-10-03) - the preferred tool for overriding config is "--color", and we should be modeling that consistently We can individually revert the few commits necessary to restore some useful tests (which will be done on top of this patch). Note that this isn't a pure revert; we'll keep the test added in t3701, but mark it as failure for now. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-10-17ssh: introduce a 'simple' ssh variantLibravatar Brandon Williams1-4/+23
When using the 'ssh' transport, the '-o' option is used to specify an environment variable which should be set on the remote end. This allows git to send additional information when contacting the server, requesting the use of a different protocol version via the 'GIT_PROTOCOL' environment variable like so: "-o SendEnv=GIT_PROTOCOL". Unfortunately not all ssh variants support the sending of environment variables to the remote end. To account for this, only use the '-o' option for ssh variants which are OpenSSH compliant. This is done by checking that the basename of the ssh command is 'ssh' or the ssh variant is overridden to be 'ssh' (via the ssh.variant config). Other options like '-p' and '-P', which are used to specify a specific port to use, or '-4' and '-6', which are used to indicate that IPV4 or IPV6 addresses should be used, may also not be supported by all ssh variants. Currently if an ssh command's basename wasn't 'plink' or 'tortoiseplink' git assumes that the command is an OpenSSH variant. Since user configured ssh commands may not be OpenSSH compliant, tighten this constraint and assume a variant of 'simple' if the basename of the command doesn't match the variants known to git. The new ssh variant 'simple' will only have the host and command to execute ([username@]host command) passed as parameters to the ssh command. Update the Documentation to better reflect the command-line options sent to ssh commands based on their variant.

2017-10-04color: make "always" the same as "auto" in configLibravatar Jeff King1-18/+17
It can be handy to use `--color=always` (or it's synonym `--color`) on the command-line to convince a command to produce color even if it's stdout isn't going to the terminal or a pager. What's less clear is whether it makes sense to set config variables like color.ui to `always`. For a one-shot like: git -c color.ui=always ... it's potentially useful (especially if the command doesn't directly support the `--color` option). But setting `always` in your on-disk config is much muddier, as you may be surprised when piped commands generate colors (and send them to whatever is consuming the pipe downstream). Some people have done this anyway, because: 1. The documentation for color.ui makes it sound like using `always` is a good idea, when you almost certainly want `auto`. 2. Traditionally not every command (and especially not plumbing) respected color.ui in the first place. So the confusion came up less frequently than it might have. The situation changed in 136c8c8b8f (color: check color.ui in git_default_config(), 2017-07-13), which negated point (2): now scripts using only plumbing commands (like add-interactive) are broken by this setting. That commit was fixing real issues (e.g., by making `color.ui=never` work, since `auto` is the default), so we don't want to just revert it. We could turn `always` into a noop in plumbing commands, but that creates a hard-to-explain inconsistency between the plumbing and other commands. Instead, let's just turn `always` into `auto` for all config. This does break the "one-shot" config shown above, but again, we're probably better to have simple and consistent rules than to try to special-case command-line config. There is one place where `always` should retain its meaning: on the command line, `--color=always` should continue to be the same as `--color`, overriding any isatty checks. Since the command-line parser also depends on git_config_colorbool(), we can use the existence of the "var" string to deterine whether we are serving the command-line or the config.

With more commands (that potentially change a submodule) paying attention to submodules as well as the recent discussion[1] on submodule.<name>.update, let's spell out that submodule.<name>.update is strictly to be used for configuring the "submodule update" command and not to be obeyed by other commands. These other commands usually have a strict meaning of what they should do (i.e. checkout, reset, rebase, merge) as well as have their name overlapping with the modes possible for submodule.<name>.update. [1] https://public-inbox.org/git/4283F0B0-BC1C-4ED1-8126-7E512D84484B@gmail.com/ submodule.<name>.update was set to "none", triggering unexpected behavior as the submodule was thought to never be touched. However a newer version of Git taught 'git pull --rebase' to also populate and rebase submodules if they were active. The newer options such as submodule.active and command specific flags would not have triggered unexpected behavior.

2017-08-23refs: retry acquiring reference locks for 100msLibravatar Michael Haggerty1-0/+6
The philosophy of reference locking has been, "if another process is changing a reference, then whatever I'm trying to do to it will probably fail anyway because my old-SHA-1 value is probably no longer current". But this argument falls down if the other process has locked the reference to do something that doesn't actually change the value of the reference, such as `pack-refs` or `reflog expire`. There actually *is* a decent chance that a planned reference update will still be able to go through after the other process has released the lock. So when trying to lock an individual reference (e.g., when creating "refs/heads/master.lock"), if it is already locked, then retry the lock acquisition for approximately 100 ms before giving up. This should eliminate some unnecessary lock conflicts without wasting a lot of time. Add a configuration setting, `core.filesRefLockTimeout`, to allow this setting to be tweaked. Note: the function `get_files_ref_lock_timeout_ms()` cannot be private to the files backend because it is also used by `write_pseudoref()` and `delete_pseudoref()`, which are defined in `refs.c` so that they can be used by other reference backends.

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>

`git config --bool xxx.yyy` returns `true` for `[xxx]yyy` but `false` for `[xxx]yyy=` or `[xxx]yyy=""`. This is tested in t1300-repo-config.sh since 09bc098c2. Signed-off-by: Andreas Heiduk <asheiduk@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-07-06Merge branch 'xz/send-email-batch-size'Libravatar Junio C Hamano1-0/+10
"git send-email" learned to overcome some SMTP server limitation that does not allow many pieces of e-mails to be sent over a single session. * xz/send-email-batch-size: send-email: --batch-size to work around some SMTP server limit
2017-07-05send-email: --batch-size to work around some SMTP server limitLibravatar xiaoqiang zhao1-0/+10
Some email servers (e.g. smtp.163.com) limit the number emails to be sent per session (connection) and this will lead to a faliure when sending many messages. Teach send-email to disconnect after sending a number of messages (configurable via the --batch-size=<num> option), wait for a few seconds (configurable via the --relogin-delay=<seconds> option) and reconnect, to work around such a limit. Also add two configuration variables to give these options the default. Note: We will use this as a band-aid for now, but in the longer term, we should look at and react to the SMTP error code from the server; Xianqiang reports that 450 and 451 are returned by problematic servers. cf. https://public-inbox.org/git/7993e188.d18d.15c3560bcaf.Coremail.zxq_yx_007@163.com/ Signed-off-by: xiaoqiang zhao <zxq_yx_007@163.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
