* Merge branch 'je/pager-do-not-recurse'Junio C Hamano2014-06-06
|\ | | | | | | | | | | | | | | | | We used to unconditionally disable the pager in the pager process we spawn to feed out output, but that prevented people who want to run "less" within "less" from doing so. * je/pager-do-not-recurse: pager: do allow spawning pager recursively

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 88e8f908f2b0c56f9ccf8134d8ff9f689af9cc84, which tried to allow GIT_PAGER="git -p column --mode='dense color'" git -p branch and still wanted to avoid "git -p column" to invoke itself. However, this falls into "don't do that -p then" category. In particular, inside "git log", with results going through less, a potentially interesting commit may be found and from there inside "less", the user may want to execute "git show <commit>". Before the commit being reverted, this used to show the patch in less but it no longer does.

* | pager: remove 'S' from $LESS by defaultMatthieu Moy2014-05-07
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, Git used to set $LESS to -FRSX if $LESS was not set by the user. The FRX flags actually make sense for Git (F and X because sometimes the output Git pipes to less is short, and R because Git pipes colored output). The S flag (chop long lines), on the other hand, is not related to Git and is a matter of user preference. Git should not decide for the user to change LESS's default. More specifically, the S flag harms users who review untrusted code within a pager, since a patch looking like: -old code; +new good code; [... lots of tabs ...] malicious code; would appear identical to: -old code; +new good code; Users who prefer the old behavior can still set the $LESS environment variable to -FRSX explicitly, or set core.pager to 'less -S'. The documentation in config.txt is made a bit longer to keep both an example setting the 'S' flag (needed to recover the old behavior) and an example showing how to unset a flag set by Git.

* pager: turn on "cat" optimization for DEFAULT_PAGERJeff King2013-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the user specifies a pager of "cat" (or the empty string), whether it is in the environment or from config, we automagically optimize it out to mean "no pager" and avoid forking at all. We treat an empty pager variable similary. However, we did not apply this optimization when DEFAULT_PAGER was set to "cat" (or the empty string). There is no reason to treat DEFAULT_PAGER any differently. The optimization should not be user-visible (unless the user has a bizarre "cat" in their PATH). And even if it is, we are better off behaving consistently between the compile-time default and the environment and config settings. The stray "else" we are removing from this code was introduced by 402461a (pager: do not fork a pager if PAGER is set to empty., 2006-04-16). At that time, the line directly above used: if (!pager) pager = "less"; as a fallback, meaning that it could not possibly trigger the optimization. Later, a3d023d (Provide a build time default-pager setting, 2009-10-30) turned that constant into a build-time setting which could be anything, but didn't loosen the "else" to let DEFAULT_PAGER use the optimization.

* pager: drop "wait for output to run less" hackJeff King2012-06-05
| | | | | | | | | | | | | | | | | | | Commit 35ce862 (pager: Work around window resizing bug in 'less', 2007-01-24) causes git's pager sub-process to wait to receive input after forking but before exec-ing the pager. To handle this, run-command had to grow a "pre-exec callback" feature. Unfortunately, this feature does not work at all on Windows (where we do not fork), and interacts poorly with run-command's parent notification system. Its use should be discouraged. The bug in less was fixed in version 406, which was released in June 2007. It is probably safe at this point to remove our workaround. That lets us rip out the preexec_cb feature entirely.

* Stop starting pager recursivelyNguyễn Thái Ngọc Duy2012-04-27
| | | | | | | | | | | | | | | | | git-column can be used as a pager for other git commands, something like this: GIT_PAGER="git -p column --mode='dense color'" git -p branch The problem with this is that "git -p column" also has $GIT_PAGER set so the pager runs itself again as another pager. The end result is an infinite loop of forking. Other git commands have the same problem if being abused this way. Check if $GIT_PAGER is already set and stop launching another pager.

* | pager: find out the terminal width before spawning the pagerZbigniew Jędrzejewski-Szmek2012-02-13
|/ | | | | | | | | | | | | | | | term_columns() checks for terminal width via ioctl(2) on the standard output, but we spawn the pager too early for this check to be useful. The effect of this buglet can be observed by opening a wide terminal and running "git -p help --all", which still shows 80-column output, while "git help --all" uses the full terminal width. Run the check before we spawn the pager to fix this. While at it, move term_columns() to pager.c and export it from cache.h so that callers other than the help subsystem can use it.

* setup_pager: set GIT_PAGER_IN_USEJeff King2011-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | We have always set a global "spawned_pager" variable when we start the pager. This lets us make the auto-color decision later in the program as as "we are outputting to a terminal, or to a pager which can handle colors". Commit 6e9af86 added support for the GIT_PAGER_IN_USE environment variable. An external program calling git (e.g., git-svn) could set this variable to indicate that it had already started the pager, and that the decision about auto-coloring should take that into account. However, 6e9af86 failed to do the reverse, which is to tell external programs when git itself has started the pager. Thus a git command implemented as an external script that has the pager turned on (e.g., "git -p stash show") would not realize it was going to a pager, and would suppress colors. This patch remedies that; we always set GIT_PAGER_IN_USE when we start the pager, and the value is respected by both this program and any spawned children.

* Make 'git var GIT_PAGER' always print the configured pagerJonathan Nieder2010-02-14
| | | | | | | | | | | | | | | | | | | | | | Scripted commands that want to use git’s configured pager know better than ‘git var’ does whether stdout is going to be a tty at the appropriate time. Checking isatty(1) as git_pager() does now won’t cut it, since the output of git var itself is almost never a terminal. The symptom is that when used by humans, ‘git var GIT_PAGER’ behaves as it should, but when used by scripts, it always returns ‘cat’! So avoid tricks with isatty() and just always print the configured pager. This does not fix the callers to check isatty(1) themselves yet. Nevertheless, this patch alone is enough to fix 'am --interactive'. Thanks to Sebastian Celis for the report and Jeff King for the analysis.

Examples: On (old) solaris systems, /usr/bin/less (typically the first less found) doesn't understand the default arguments (FXRS), which forces users to alter their environment (PATH, GIT_PAGER, LESS, etc) or have a local or global gitconfig before paging works as expected. On Debian systems, by policy packages must fall back to the 'pager' command, so that changing the target of the /usr/bin/pager symlink changes the default pager for all packages at once.

* pager: do wait_for_pager on signal deathJeff King2009-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Since ea27a18 (spawn pager via run_command interface), the original git process actually does git work, and the pager is a child process (actually, on Windows it has always been that way, since Windows lacks fork). After spawning the pager, we register an atexit() handler that waits for the pager to finish. Unfortunately, that handler does not always run. In particular, if git is killed by a signal, then we exit immediately. The calling shell then thinks that git is done; however, the pager is still trying to run and impact the terminal. The result can be seen by running a long git process with a pager (e.g., "git log -p") and hitting ^C. Depending on your config, you should see the shell prompt, but pressing a key causes the pager to do any terminal de-initialization sequence. This patch just intercepts any death-dealing signals and waits for the pager before dying. Under typical less configuration, that means hitting ^C will cause git to stop generating output, but the pager will keep running.

* | spawn pager via run_command interfaceJeff King2008-07-25
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has two important effects: 1. The pager is now the _child_ process, instead of the parent. This means that whatever spawned git (e.g., the shell) will see the exit code of the git process, and not the pager. 2. The mingw and regular code are now unified, which makes the setup_pager function much simpler. There are two caveats: 1. We used to call execlp directly on the pager, followed by trying to exec it via the shall. We now just use the shell (which is what mingw has always done). This may have different results for pager names which contain shell metacharacters. It is also slightly less efficient because we unnecessarily run the shell; however, pager spawning is by definition an interactive task, so it shouldn't be a huge problem. 2. The git process will remain in memory while the user looks through the pager. This is potentially wasteful. We could get around this by turning the parent into a meta-process which spawns _both_ git and the pager, collects the exit status from git, waits for both to end, and then exits with git's exit code.

| | | | | | | | | | | | | | | | | | | When deciding whether or not to turn on automatic color support, git_config_colorbool checks whether stdout is a tty.

This is a minimum change in the sense that it restores the old behaviour of not even reading config in setup_git_directory(), but have the core.pager honored when we know it matters. Note that this does not cover "git -p --git-dir where command"; the -p option immediately trigger the pager settings before we even see --git-dir to learn where the configuration file is, so we will end up reading the configuration from the place where we would _normally_ find the git repository.
