NAME¶
Code::TidyAll::Git::Prereceive - Git pre-receive hook that requires files to be
tidyall'd
VERSION¶
version 0.20
SYNOPSIS¶
In .git/hooks/pre-receive:
#!/usr/bin/perl
use Code::TidyAll::Git::Prereceive;
use strict;
use warnings;
Code::TidyAll::Git::Prereceive->check();
# or
my $input = do { local $/; <STDIN> };
# Do other things with $input here
my $hook = Code::TidyAll::Git::Prereceive->new();
if (my $error = $hook->check_input($input)) {
die $error;
}
DESCRIPTION¶
This module implements a Git pre-receive hook
<
http://git-scm.com/book/en/Customizing-Git-Git-Hooks> that checks if
all pushed files are tidied and valid according to tidyall, and rejects the
push if not.
This is typically used to validate pushes from multiple developers to a shared
repo, possibly on a remote server.
See also Code::TidyAll::Git::Precommit, which operates locally.
METHODS¶
- check (key/value params...)
- An all-in-one class method. Reads commit info from standard input, then
checks that all files being added or modified in this push are tidied and
valid according to tidyall. If not, then the entire push is rejected and
the reason(s) are output to the client. e.g.
% git push
Counting objects: 9, done.
...
remote: [checked] lib/CHI/Util.pm
remote: Code before strictures are enabled on line 13 [TestingAndDebugging::RequireUseStrict]
remote:
remote: 1 file did not pass tidyall check
To ...
! [remote rejected] master -> master (pre-receive hook declined)
The configuration file ("tidyall.ini" or ".tidyallrc")
must be checked into git in the repo root directory, i.e. next to the .git
directory.
In an emergency the hook can be bypassed by pushing the exact same set of
commits 3 consecutive times (configurable via
"allow_repeated_push"):
% git push
...
remote: 1 file did not pass tidyall check
% git push
...
*** Identical push seen 2 times
remote: 1 file did not pass tidyall check
% git push
...
*** Identical push seen 3 times
*** Allowing push to proceed despite errors
Or you can disable the hook in the repo being pushed to, e.g. by renaming
.git/hooks/pre-receive.
If an unexpected runtime error occurs, it is reported but by default the
commit will be allowed through (see "reject_on_error").
Passes mode = "commit" by default; see modes.
Key/value parameters:
- allow_repeated_push
- Number of times a push must be repeated exactly after which it will be let
through regardless of errors. Defaults to 3. Set to 0 or undef to disable
this feature.
- conf_name
- Conf file name to search for instead of the defaults.
- extra_conf_files
- A listref of extra configuration files referred to from the main
configuration file, e.g.
extra_conf_files => ['perlcriticrc', 'perltidyrc']
These files will be pulled out of the repo alongside the main configuration
file. If you don't list them here then you'll get errors like 'cannot find
perlcriticrc' when the hook runs.
- git_path
- Path to git to use in commands, e.g. '/usr/bin/git' or
'/usr/local/bin/git'. By default, just uses 'git', which will search the
user's PATH.
- reject_on_error
- Whether "check()" should reject the commit when an unexpected
runtime error occurs. By default, the error will be reported but the
commit will be allowed.
- tidyall_class
- Subclass to use instead of Code::TidyAll
- tidyall_options
- Hashref of options to pass to the Code::TidyAll constructor. You can use
this to override the default options
mode => 'commit',
quiet => 1,
or pass additional options.
- new (key/value params...)
- Constructor. Takes the same parameters documented in check(),
above, and returns a new object which you can then call
"check_input" on.
- check_input (input)
- Run a check on input, the text block of lines that came from
standard input. You can call this manually before or after you do other
processing on the input. Returns an error string if there was a problem,
undef if no problems.
KNOWN BUGS¶
This hook will ignore any files with only a single line of content (no
newlines), as an imperfect way of filtering out symlinks.
