Microsoft recommends you install a download manager. Microsoft Download Manager. Manage all your internet downloads with this easy-to-use manager.

It features a simple interface with many customizable options:. Download multiple files at one time Download large files quickly and reliably Suspend active downloads and resume downloads that have failed.

Yes, install Microsoft Download Manager recommended No, thanks. What happens if I don't install a download manager? Why should I install the Microsoft Download Manager? if you do not have a download manager installed, and still want to download the file s you've chosen, please note: You may not be able to download multiple files at the same time.

In this case, you will have to download the files individually. local" locally and put that in bootstrap file. So if you want to keep a log of all the errors even after page reloads for help in debugging, maybe , running the PHP development server can be useful. This means they cannot be disabled by dynamically altering the error level at run time within that page. Ex, rename index. php to index. php, then re-create index. php' ;? see more information about php 5.

I had the problem that if there was an error, php would just give me a blank page. But simply running the file in a different directory allowed it to show errors! I erased the file and now errors are displayed normally. It might also help to turn error logging off.

To expand upon the note by chris at ocproducts dot com. Zeev Suraski suggests that a simple way to use the defined levels of error reporting with your custom error handlers is to add the following line to the top of your error handling function: if! If you have a customer error handler that does not output warnings, you may get a white screen of death if a "require" fails. Unset values passed by reference won't trigger a notice. php include 'config. php' ; include 'foo.

If the suppressor is removed, this works as expected. php will achieve the same result. This is contrary to the note above which says that the two instructions are equivalent. Only display php errors to the developer

A unit configuration file whose name ends in ". service " encodes information about a process controlled and supervised by systemd. This man page lists the configuration options specific to this unit type.

See systemd. unit 5 for the common options of all unit configuration files. The common configuration items are configured in the generic [Unit] and [Install] sections.

The service specific configuration options are configured in the [Service] section. Additional options are listed in systemd. exec 5 , which define the execution environment the commands are executed in, and in systemd.

kill 5 , which define the way the processes of the service are terminated, and in systemd. resource-control 5 , which configure resource control settings for the processes of the service. If SysV init compat is enabled, systemd automatically creates service units that wrap SysV init scripts the service name is the same as the name of the script, with a ".

service " suffix added ; see systemd-sysv-generator 8. The systemd-run 1 command allows creating. service and. scope units dynamically and transiently from the command line. It is possible for systemd services to take a single argument via the " service argument. service " syntax. Such services are called "instantiated" services, while the unit definition without the argument parameter is called a "template".

An example could be a dhcpcd. service service template which takes a network interface as a parameter to form an instantiated service. unit 5 for details.

Socket activated services are automatically ordered after their activating. Services also pull in all. Additional implicit dependencies may be added as result of execution and resource control parameters as documented in systemd.

exec 5 and systemd. resource-control 5. These ensure that normal service units pull in basic system initialization, and are terminated cleanly prior to system shutdown. Only services involved with early boot or late system shutdown should disable this option.

Instanced service units i. service units with an " " in their name are assigned by default a per-template slice unit see systemd. slice 5 , named after the template unit, containing all instances of the specific template. This slice is normally stopped at shutdown, together with all template instances. slice or another suitable slice in the template unit. Also see systemd. Service unit files may include [Unit] and [Install] sections, which are described in systemd.

unit 5. Service unit files must include a [Service] section, which carries information about the service and the process it supervises. A number of options that may be used in this section are shared with other unit types. These options are documented in systemd. exec 5 , systemd. kill 5 and systemd. The options specific to the [Service] section of service units are the following:. Configures the process start-up type for this service unit. One of simple , exec , forking , oneshot , dbus , notify or idle :.

In this mode, if the process offers functionality to other processes on the system, its communication channels should be installed before the service is started up e. sockets set up by systemd, via socket activation , as the service manager will immediately proceed starting follow-up units, right after creating the main service process, and before executing the service's binary.

The exec type is similar to simple , but the service manager will consider the unit started immediately after the main service binary has been executed. The service manager will delay starting of follow-up units until that point. Or in other words: simple proceeds with further jobs right after fork returns, while exec will not proceed before both fork and execve in the service process succeeded.

The parent process is expected to exit when start-up is complete and all communication channels are set up. The child continues to run as the main service process, and the service manager will consider the unit started when the parent process exits.

This is the behavior of traditional UNIX services. systemd will proceed with starting follow-up units as soon as the parent process exits. Behavior of oneshot is similar to simple ; however, the service manager will consider the unit up after the main process exits. It will then start follow-up units. systemd will proceed with starting follow-up units after the D-Bus bus name has been acquired.

Service units with this option configured implicitly gain dependencies on the dbus. socket unit. A service unit of this type is considered to be in the activating state until the specified bus name is acquired. It is considered activated while the bus name is taken. Once the bus name is released the service is considered being no longer functional which has the effect that the service manager attempts to terminate any remaining processes belonging to the service.

systemd will proceed with starting follow-up units after this notification message has been sent. Behavior of idle is very similar to simple ; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving of output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s timeout, after which the service program is invoked anyway.

However, as this service type won't propagate service start-up failures and doesn't allow ordering of other units against completion of initialization of the service which for example is useful if clients need to connect to the service through some form of IPC, and the IPC channel is only established by the service itself — in contrast to doing this ahead of time through socket or bus activation or similar , it might not be sufficient for many cases.

If so, notify or dbus the latter only in case the service provides a D-Bus interface are the preferred options as they allow service program code to precisely schedule when to consider the service started up successfully and when to proceed with follow-up units.

Finally, exec might be an option for cases where it is enough to ensure the service binary is invoked, and where the service binary itself executes no or little initialization on its own and its initialization is unlikely to fail. Note that using any type other than simple possibly delays the boot process, as the service manager needs to wait for service initialization to complete. It is hence recommended not to needlessly use any types other than simple.

Also note it is generally not recommended to use idle or oneshot for long-running services. Specifies when the manager should consider the service to be finished. One of main or cgroup :. If set to cgroup , the service will be considered running as long as at least one process in the cgroup has not exited. It is well suited for transient or automatically generated services, such as graphical applications inside of a desktop environment. Takes a boolean value that specifies whether the service shall be considered active even when all its processes exited.

Defaults to no. Takes a boolean value that specifies whether systemd should try to guess the main PID of a service if it cannot be determined reliably.

The guessing algorithm might come to incorrect conclusions if a daemon consists of more than one process. If the main PID cannot be determined, failure detection and automatic restarting of a service will not work reliably.

Defaults to yes. Takes a path referring to the PID file of the service. The service manager will read the PID of the main process of the service from this file after start-up of the service.

The service manager will not write to the file configured here, although it will remove the file after the service has shut down if it still exists. The PID file does not need to be owned by a privileged user, but if it is owned by an unprivileged user additional safety restrictions are enforced: the file may not be a symlink to a file owned by a different user neither directly nor indirectly , and the PID file must refer to a process already belonging to the service.

Note that PID files should be avoided in modern projects. Takes a D-Bus destination name that this service shall use. It is recommended to always set this property if known to make it easy to map the service name to the D-Bus destination. Commands with their arguments that are executed when this service is started. The value is split into zero or more command lines according to the rules described below see section "Command Lines" below.

Commands may be specified by providing multiple command lines in the same directive, or alternatively, this directive may be specified more than once with the same effect. If the empty string is assigned to this option, the list of commands to start is reset, prior assignments of this option will have no effect.

For each of the specified commands, the first argument must be either an absolute path to an executable or a simple file name without any slashes. Optionally, this filename may be prefixed with a number of special characters:. Note that these prefixes are also supported for the other command line settings, i. If more than one command is specified, the commands are invoked sequentially in the order they appear in the unit file. If one of the commands fails and is not prefixed with " - " , other lines are not executed, and the unit is considered failed.

If any of those commands not prefixed with " - " fail, the rest are not executed and the unit is considered failed.
