=head2 auto_grow_pv |
|
|
|
This looks at LVM PVs on the local host. For each one that is found, C<< parted >> is called to check if there's more that 1 GiB of free space available after it. If so, it will extend the PV partition to use the free space. |
|
|
|
This method takes no parameters. |

=head2 backup |
|
|
|
This will create a copy of the file under the C<< path::directories::backups >> directory with the datestamp as a suffix. The path is preserved under the backup directory. The path and file name are returned. |
|
|
|
By default, a failure to backup will be fatal with return code C<< 1 >> for safety reasons. If the file is critical, you can set C<< fatal => 0 >> and an empty string will be returned on error. |
|
|
|
This method can work on local and remote systems. |
|
|
|
If the backup failed, an empty string is returned. |
|
|
|
Parameters; |
|
|
|
=head3 fatal (optional, default 1) |
|
|
|
If set to C<< 0 >>, any problem with the backup will be ignored and an empty string will be returned. |
|
|
|
=head3 file (required) |
|
|
|
This is the path and file name of the file to be backed up. Fully paths must be used. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be backed up on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
=head3 remote_user (optional) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

Parameters; |
|
|
|
=head3 mode (required) |
|
|
|
This is the numeric mode to set on the file. It expects four digits to cover the sticky bit, but will work with three digits. It also supports the C<< + >> and C<< - >> formats, like C<< a+x >> or C<< g-w >>. |
|
|
|
=head3 path (required) |
|
|
|
This is the file or directory to change the mode on. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be backed up on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
=head3 remote_user (optional) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

=head2 compress |
|
|
|
This compresses a local or remote file, using bzip2. It returns C<< 0 >> on success, and C<< 1 >> on failure. |
|
|
|
B<< NOTE >>: When compressing a remote file, a ten minute (600 second) timeout is used. If you think a compression could take longer, either use the C<< timeout >> parameter below, or call this method on the remote machine, if possible. |
|
|
|
Parameters; |
|
|
|
=head3 file (required) |
|
|
|
This is the full path to the file to compress. |
|
|
|
=head3 keep (optional, default 0) |
|
|
|
When set to C<< 1 >>, the file being compressed will be kept, and the new compressed version will be saved along side it. When set to C<< 0 >>, the original file is removed, leaving the compressed file. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be copied on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
=head3 timeout (optional, default '600') |
|
|
|
This is the number of seconds that this method will wait for the compression to complete. If the timeout expires, C<< 1 >> will be returned, though it is possible that the compression may still complete successfully after the connection times out. |
|
|
|
=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

=head2 copy_file |
|
|
|
This copies a file, with a few additional checks like creating the target directory if it doesn't exist, aborting if the file has already been backed up before, etc. It can copy files on the local or a remote machine. |
|
|
|
# Example |
|
$anvil->Storage->copy_file({source_file => "/some/file", target_file => "/another/directory/file"}); |
|
|
|
Returns C<< 0 >> on success, otherwise C<< 1 >>. |
|
|
|
Parameters; |
|
|
|
=head3 overwrite (optional) |
|
|
|
If this is set to 'C<< 1 >>', and if the target file exists, it will be replaced. |
|
|
|
If this is not passed and the target exists, this module will return 'C<< 3 >>'. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 source_file (required) |
|
|
|
This is the source file. If it isn't specified, 'C<< 1 >>' will be returned. If it doesn't exist, this method will return 'C<< 4 >>'. |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be copied on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
=head3 target_file (required) |
|
|
|
This is the target B<< file >>, not the directory to put it in. The target file name can be different from the source file name. |
|
|
|
if this is not specified, 'C<< 2 >>' will be returned. |
|
|
|
=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

=head3 copy_device |
|
|
|
This uses the C<< dd >> system call, possibly over ssh, to create a copy of the source on the destination. Being based on C<< dd >>, this works with raw block devices and to or from files. |
|
|
|
B<< Warning >>: This must be used carefully! Calling this backwards could destroy data! |
|
|
|
B<< Note >>: The caller is responsible for ensuring the data on the soure will not change during the copy. If the source is a server, make sure it's off. If the source is a file system, make sure it's unmounted. |
|
|
|
B<< Note >>: If the C<< source >> or C<< destination >> is a remote host, passwordless SSH must be configured for this to work! |
|
|
|
Parameters; |
|
|
|
=head3 block_size (optional, default '4M') |
|
|
|
This is the block size to be used for the copy. Specifically, this transtes into 'read <size> bytes, copy, read <size> bytes, copy'. This should match the size of the logical extents, block size or similar where needed. Most LVM logical extents are 4 MiB, so the default of C<< 4M >> should be fine in most cases. |
|
|
|
B<< Note >>: See C<< man dd >> for valid formatting of this option. |
|
|
|
=head3 calculate_sums (Optional, default '0') |
|
|
|
If set to C<< 1 >>, the C<< md5sum >> of the source and destination are calculated and returned. If this is not used, the returned sum fields will be an empty string. |
|
|
|
B<< Note >>: Calculating sums is highly advised, but can increase the time it takes for the copy to complete! |
|
|
|
=head3 destination (required) |
|
|
|
This is the full path to the destination (copy to) file or device. If the source is remote, used the format C<< <remote_user>@target:/path/to/file >>. |
|
|
|
B<< Note >>: Only the source OR the destination can be remote, not both! |
|
|
|
=head3 source (required) |
|
|
|
This is the full path to the source (copy from) file or device. If the source is remote, used the format C<< <remote_user>@target:/path/to/file >>. |
|
|
|
B<< Note >>: Only the source OR the destination can be remote, not both! |
|
|
|
=head3 status_file (required) |
|
|
|
This is the path to the status file used to record the progress of the copy. This will contain a parsed version of the C<< dd ... --status=progress >> output. When the copy is done, if C<< calculate_sums >> is set, then the C<< source=<sum> >> and C<< destination=<sum> >> will be recorded, marking the completion of the copy. If not set, those same variables will be written without a value, still marking the end of the copy. If there is a problem, the last line of the file be C<< failed=<reason> >>. |

=head3 delete_file |
|
|
|
This deletes a file. Pretty much what it says on the tin. When run locally, it uses C<< unlink >>. When run on a remote machine, it uses C<< rm -f >>. As such, this will not delete directories, nor will it delete recursively. |
|
|
|
# Example |
|
$anvil->Storage->delete_file({file => "/some/file"}); |
|
|
|
On success, or if the file is already gone, C<< 0 >> is returned. On failure, C<< 1 >> is returned. |
|
|
|
Parameters; |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 file (required) |
|

=head3 target (optional) |

If set, the file will be copied on the target machine. This must be either an IP address or a resolvable host name. |
|
|

=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

=head2 move_file |
|
|
|
This moves a file, with a few additional checks like creating the target directory if it doesn't exist, aborting if the file already exists in the target, etc. It can move files on the local or a remote machine. |
|
|
|
As with the system copy, the target can be a directory (denoted with an ending c<< / >>), or a it can be renamed in the process (but not ending with C<< / >>). |
|
|
|
# Example moving |
|
$anvil->Storage->move_file({source_file => "/some/file", target_file => "/another/directory/"}); |
|
|
|
# Example moving with a rename at the same time |
|
$anvil->Storage->move_file({source_file => "/some/file", target_file => "/another/directory/new_name"}); |
|
|
|
Returns C<< 0 >> on success, otherwise C<< 1 >>. |
|
|
|
Parameters; |
|
|
|
=head3 overwrite (optional) |
|
|
|
If this is set to 'C<< 1 >>', and if the target file exists, it will be replaced. |
|
|
|
If this is not passed and the target exists, this module will return 'C<< 3 >>'. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 source_file (required) |
|
|
|
This is the source file. If it isn't specified, 'C<< 1 >>' will be returned. If it doesn't exist, this method will return 'C<< 4 >>'. |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be copied on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
=head3 target_file (required) |
|
|
|
This is the target B<< file >>, not the directory to put it in. The target file name can be different from the source file name. |
|
|
|
if this is not specified, 'C<< 2 >>' will be returned. |
|
|
|
=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

=head2 read_config |
|
|
|
This method is used to read C<< Anvil::Tools >> style configuration files. These configuration files are in the format: |
|
|
|
# This is a comment for the 'a::b::c' variable |
|
a::b::c = x |
|
|
|
A configuration file can be read in like this; |
|
|
|
$anvil->Storage->read_config({file => "test.conf"}); |
|
|
|
In this example, the file 'C<< test.conf >>' will be searched for in the directories returned by 'C<< $anvil->Storage->search_directories >>'. |
|
|
|
Any line starting with '#' is a comment and is ignored. Preceding white spaces are allowed and also ignored. |
|
|
|
Any line in the format 'x = y' is treated as a variable / value pair, split on the first 'C<< = >>'. Whitespaces on either side of the 'C<< = >>' are removed and ignored. However, anything after the first non-whitespace character is treated as data an unmolested. This includes addition 'C<< = >>' characters, white spaces and so on. The exception is that trailing white spaces are cropped and ignored. If nothing comes after the 'C<< = >>', the variable is set to a blank string. |
|
|
|
Successful read will return 'C<< 0 >>'. Non-0 is an error; |
|
C<< 0 >> = OK |
|
C<< 1 >> = Invalid or missing file name |
|
C<< 2 >> = File not found |
|
C<< 3 >> = File not readable |
|
|
|
Parameters; |
|
|
|
=head3 file (optional, default file stored in 'path::configs::anvil.conf') |
|
|
|
This is the configuration file to read. |
|
|
|
If the 'C<< file >>' parameter starts with 'C<< / >>', the exact path to the file is used. Otherwise, this method will search for the file in the list of directories returned by 'C<< $anvil->Storage->search_directories >>'. The first match is read in. |
|
|
|
All variables are stored in the root of 'C<< $anvil->data >>', allowing for configuration files to override internally set variables. |
|
|
|
For example, if you set: |
|
|
|
$anvil->data->{a}{b}{c} = "1"; |
|
|
|
Then you read in a config file with: |
|
|
|
a::b::c = x |
|
|
|
Then 'C<< $anvil->data->{a}{b}{c} >>' will now contain 'C<< x >>'. |

If it fails to find the file, or the file is not readable, 'C<< !!error!! >>' is returned. |
|
|
|
Parameters; |
|
|
|
=head3 cache (optional) |
|
|
|
This is an optional parameter that controls whether the file is cached in case something else tries to read the same file later. By default, all read files are cached. Set this to C<< 0 >> to disable caching. This should only be needed when reading large files. |
|
|
|
=head3 file (required) |
|
|
|
This is the name of the file to read. When reading from a remote machine, it must be a full path and file name. |
|
|
|
=head3 force_read (optional, default '1') |
|
|
|
This is an optional parameter that, if set to C<< 0 >>, will allow an existing cached copy of the file to be used instead of actually reading the file from disk (again). |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 remote_user (optional) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |
|
|
|
=head3 secure (optional, default 0) |
|
|
|
If set to C<< 1 >>, the body of the read file will be treated as sensitive from a logging perspective. |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be read from the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
The file will be copied to the local system using C<< $anvil->Storage->rsync() >> and stored in C<< /tmp/<file_path_and_name>.<target> >>. if C<< cache >> is set, the file will be preserved locally. Otherwise it will be deleted once it has been read into memory. |
|
|
|
B<< Note >>: the temporary file will be prefixed with the path to the file name, with the C<< / >> converted to C<< _ >>. |

=head2 rsync |
|
|
|
This method copies a file or directory (and its contents) to or from a remote machine using C<< rsync >> and an C<< expect >> wrapper. |
|
|
|
This supports the source B<< or >> the destination being remote, so the C<< source >> or C<< destination >> paramter can be in the format C<< <remote_user>@<target>:/file/path >>. If neither parameter is remove, a local C<< rsync >> operation will be performed. |
|
|
|
On success, C<< 0 >> is returned. If a problem arises, C<< 1 >> is returned. |
|
|
|
B<< NOTE >>: This method does not take C<< remote_user >> or C<< target >>. These are parsed off the C<< source >> or C<< destination >> parameter. |
|
|
|
Parameters; |
|
|
|
=head3 destination (required) |
|
|
|
This is the destination being copied to. Be careful with the closing C<< / >>! Generally you will always want to have the destination end in a closing slash, to ensure the files go B<< under >> the estination directory. The same as is the case when using C<< rsync >> directly. |
|
|
|
=head3 password (optional) |
|
|
|
This is the password used to connect to the target machine (if either the source or target is remote). |
|
|
|
=head3 port (optional, default 22) |
|
|
|
This is the TCP port used to connect to the target machine. |
|
|
|
=head3 source (required) |
|
|
|
This is the file to copy via rsync. |
|
|
|
The source can be a directory, or end in a wildcard (ie: C<< .../* >>) to copy multiple files/directories at the same time. |
|
|
|
=head3 switches (optional, default -avS) |
|
|
|
These are the switches to pass to C<< rsync >>. If you specify this and you still want C<< -avS >>, be sure to include it. This parameter replaces the default. |
|
|
|
B<< NOTE >>: If C<< port >> is specified, C<< -e 'ssh -p <port> >> will be appended automatically, so you do not need to specify this. |
|
|
|
=head3 try_again (optional, default 1) |
|
|
|
If this is set to C<< 1 >>, and if a conflict is found with the SSH RSA key (C<< Offending key in... >> error) when trying the C<< rsync >> call, the offending key will be removed and a second attempt will be made. On the second attempt, this is set to C<< 0 >> to prevent a recursive loop if the removal fails. |
|
|
|
B<< NOTE >>: This is the default to better handle a rebuilt node, dashboard or DR machine. Of course, this is a possible security problem so please consider it's use on a case by case basis. |

=head2 search_directories |
|
|
|
This method returns an array reference of directories to search within for files and directories. |
|
|
|
Parameters; |
|
|
|
=head3 directories (optional) |
|
|
|
This accepts either an array reference of directories to search, or a comma-separated string of directories to search (which will be converted to an array). When passed, this sets the internal list of directories to search. |
|
|
|
By default, it is set to all directories in C<< @INC >>, 'C<< path::directories::tools >> (our tools) and the C<< $ENV{'PATH'} >> variables, minus directories that don't actually exist. The returned array is sorted alphabetically. |
|
|
|
=head3 initialize (optional) |
|
|
|
If this is set, the list of directories to search will be set to 'C<< @INC >>' + 'C<< $ENV{'PATH'} >>' + 'C<< path::directories::tools >>'. |
|
|
|
NOTE: You don't need to call this manually unless you want to reset the list. Invoking Anvil::Tools->new() causes this to be called automatically. |

=head2 update_config |
|
|
|
This takes a variable name and value and updates the C<< path::configs::anvil.conf >> file. If the given variable is already set to the requested value, nothing further is done. |
|
|
|
Returns C<< 0 >> on success, C<< 1 >> on error. |
|
|
|
B<< Note >>: If the variable is not found, it is treated like an error and C<< 1 >> is returned. |
|
|
|
Parameters; |
|
|
|
=head3 append (optional, default 0) |
|
|
|
If set to C<< 1 >>, and if the variable is not found, it will be appended to the end of the config file. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 secure (optional) |
|
|
|
If set to 'C<< 1 >>', the value is treated as containing secure data for logging purposes. |
|
|
|
=head3 target (optional) |
|
|
|
If set, the config file will be updated on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
=head3 variable (required) |
|
|
|
This is the C<< a::b::c >> format variable name to update. |
|
|
|
=head3 value (optional) |
|
|
|
This is the value to set the C<< variable >> to. If this is not passed, the variable will be set to an empty string. |
|
|
|
The updated config file will be written locally in C<< /tmp/<file_name> >>, C<< $anvil->Storage->rsync() >> will be used to copy the file, and finally the local temprary copy will be removed. |
|
|
|
=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

=head2 update_file |
|
|
|
This reads in a file (if it already exists), compares it against a new body and updates it if there is a difference. This can work on remote files as well as local ones. |
|
|
|
The return code indicates success; C<< 0 >> is returns if anything goes wrong. C<< 1 >> is returned if the file was updated and C<< 2 >> is returned if the file did not need to be updated. |
|
|
|
Parameters; |
|
|
|
=head3 backup (optional, default '1') |
|
|
|
If the file needs to be updated, and if this is set to C<< 1 >>, a backup will be make before the file is updated. |
|
|
|
=head3 body (optional) |
|
|
|
This is the new body of the file. It should always be set, of course, but it is optional in case the new file is supposed to be empty. |
|
|
|
=head3 file (required) |
|
|
|
This is the full path and file name of the file being updated. |
|
|
|
=head3 port (optional, default 22) |
|

|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |
|
|
|
=head3 secure (optional) |
|
|
|
If set to 'C<< 1 >>', the C<< body >> is treated as containing secure data for logging purposes. |
|
|
|
=head3 target (optional) |
|

mode => "0644", |
|
}); |
|
|
|
Returns C<< 0 >> on success. C<< 1 >> or an error string will be returned otherwise. |
|
|
|
Parameters; |
|
|
|
=head3 backup (optional, default '1') |
|
|
|
When writing to a file that already exists, and C<< overwrite >> is true, the existing backup will be backed up prior to being rewritten. |
|
|
|
=head3 binary (optional, default '0') |
|
|
|
When set to '1', this indicates that the body is binary data, which prevents logging of the file body. |
|
|
|
=head3 body (optional) |
|
|
|
This is the contents of the file. If it is blank, an empty file will be created (similar to using 'C<< touch >>' on the command line). |
|
|
|
=head3 file (required) |
|
|
|
This is the name of the file to write. |
|
|
|
NOTE: The file must include the full directory it will be written into. |
|
|
|
=head3 group (optional, default is the main group of the user running the program) |
|
|
|
This is the group name or group ID to set the ownership of the file to. |
|
|
|
=head3 mode (optional) |
|
|
|
This is the B<< quoted >> numeric mode to set on the file. It expects four digits to cover the sticky bit, but will work with three digits. |
|
|
|
=head3 overwrite (optional) |
|
|
|
Normally, if the file already exists, it won't be overwritten. Setting this to 'C<< 1 >>' will cause the file to be overwritten. |
|
|
|
=head3 port (optional, default 22) |
|
|
|
If C<< target >> is set, this is the TCP port number used to connect to the remote machine. |
|
|
|
=head3 password (optional) |
|
|
|
If C<< target >> is set, this is the password used to log into the remote system as the C<< remote_user >>. If it is not set, an attempt to connect without a password will be made (though this will usually fail). |
|
|
|
=head3 secure (optional) |
|
|
|
If set to 'C<< 1 >>', the body is treated as containing secure data for logging purposes. |
|
|
|
=head3 target (optional) |
|
|
|
If set, the file will be written on the target machine. This must be either an IP address or a resolvable host name. |
|
|
|
The file will be written locally in C<< /tmp/<file_name> >>, C<< $anvil->Storage->rsync() >> will be used to copy the file, and finally the local temprary copy will be removed. |
|
|
|
=head3 user (optional, default is the user running the program) |
|
|
|
This is the user name or user ID to set the ownership of the file to. |
|
|
|
=head3 remote_user (optional, default root) |
|
|
|
If C<< target >> is set, this is the user account that will be used when connecting to the remote system. |

|
|
|
Parameters; |
|
|
|
