1056 | Log the given C<$msg> at the given C<$level>. |
|
|
1057 | |
|
|
1058 | If L<AnyEvent::Log> is not loaded then this function makes a simple test |
|
|
1059 | to see whether the message will be logged. If the test succeeds it will |
|
|
1060 | load AnyEvent::Log and call C<AnyEvent::Log::log> - consequently, look at |
|
|
1061 | the L<AnyEvent::Log> documentation for details. |
|
|
1062 | |
|
|
1063 | If the test fails it will simply return. Right now this happens when a |
|
|
1064 | numerical loglevel is used and it is larger than the level specified via |
|
|
1065 | C<$ENV{PERL_ANYEVENT_VERBOSE}>. |
|
|
1066 | |
|
|
1067 | If you want to sprinkle loads of logging calls around your code, consider |
|
|
1068 | creating a logger callback with the C<AnyEvent::Log::logger> function, |
|
|
1069 | which can reduce typing, codesize and can reduce the logging overhead |
|
|
1070 | enourmously. |

1154 | Here be danger! |
|
|
1155 | |
|
|
1156 | As Pauli would put it, "Not only is it not right, it's not even wrong!" - |
|
|
1157 | there are so many things wrong with AnyEvent::Handle::UDP, most notably |
|
|
1158 | its use of a stream-based API with a protocol that isn't streamable, that |
|
|
1159 | the only way to improve it is to delete it. |
|
|
1160 | |
|
|
1161 | It features data corruption (but typically only under load) and general |
|
|
1162 | confusion. On top, the author is not only clueless about UDP but also |
|
|
1163 | fact-resistant - some gems of his understanding: "connect doesn't work |
|
|
1164 | with UDP", "UDP packets are not IP packets", "UDP only has datagrams, not |
|
|
1165 | packets", "I don't need to implement proper error checking as UDP doesn't |
|
|
1166 | support error checking" and so on - he doesn't even understand what's |
|
|
1167 | wrong with his module when it is explained to him. |

1182 | AnyEvent is good for non-blocking stuff, but it can't detect file or |
|
|
1183 | path changes (e.g. "watch this directory for new files", "watch this |
|
|
1184 | file for changes"). The L<AnyEvent::Filesys::Notify> module promises to |
|
|
1185 | do just that in a portbale fashion, supporting inotify on GNU/Linux and |
|
|
1186 | some weird, without doubt broken, stuff on OS X to monitor files. It can |
|
|
1187 | fall back to blocking scans at regular intervals transparently on other |
|

1188 | platforms, so it's about as portable as it gets. |

1948 | The following environment variables are used by this module or its |
2038 | AnyEvent supports a number of environment variables that tune the |
1949 | submodules. |
2039 | runtime behaviour. They are usually evaluated when AnyEvent is |
|
|
2040 | loaded, initialised, or a submodule that uses them is loaded. Many of |
|
|
2041 | them also cause AnyEvent to load additional modules - for example, |
|
|
2042 | C<PERL_ANYEVENT_DEBUG_WRAP> causes the L<AnyEvent::Debug> module to be |
|
|
2043 | loaded. |
1950 | |
2044 | |
1951 | Note that AnyEvent will remove I<all> environment variables starting with |
2045 | All the environment variables documented here start with |
1952 | C<PERL_ANYEVENT_> from C<%ENV> when it is loaded while taint mode is |
2046 | C<PERL_ANYEVENT_>, which is what AnyEvent considers its own |
1953 | enabled. |
2047 | namespace. Other modules are encouraged (but by no means required) to use |
|
|
2048 | C<PERL_ANYEVENT_SUBMODULE> if they have registered the AnyEvent::Submodule |
|
|
2049 | namespace on CPAN, for any submodule. For example, L<AnyEvent::HTTP> could |
|
|
2050 | be expected to use C<PERL_ANYEVENT_HTTP_PROXY> (it should not access env |
|
|
2051 | variables starting with C<AE_>, see below). |
|
|
2052 | |
|
|
2053 | All variables can also be set via the C<AE_> prefix, that is, instead |
|
|
2054 | of setting C<PERL_ANYEVENT_VERBOSE> you can also set C<AE_VERBOSE>. In |
|
|
2055 | case there is a clash btween anyevent and another program that uses |
|
|
2056 | C<AE_something> you can set the corresponding C<PERL_ANYEVENT_something> |
|
|
2057 | variable to the empty string, as those variables take precedence. |
|
|
2058 | |
|
|
2059 | When AnyEvent is first loaded, it copies all C<AE_xxx> env variables |
|
|
2060 | to their C<PERL_ANYEVENT_xxx> counterpart unless that variable already |
|
|
2061 | exists. If taint mode is on, then AnyEvent will remove I<all> environment |
|
|
2062 | variables starting with C<PERL_ANYEVENT_> from C<%ENV> (or replace them |
|
|
2063 | with C<undef> or the empty string, if the corresaponding C<AE_> variable |
|
|
2064 | is set). |
|
|
2065 | |
|
|
2066 | The exact algorithm is currently: |
|
|
2067 | |
|
|
2068 | 1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV |
|
|
2069 | 2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists |
|
|
2070 | 3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef. |
|
|
2071 | |
|
|
2072 | This ensures that child processes will not see the C<AE_> variables. |
|
|
2073 | |
|
|
2074 | The following environment variables are currently known to AnyEvent: |
1954 | |
2075 | |
1955 | =over 4 |
2076 | =over 4 |
1956 | |
2077 | |
1957 | =item C<PERL_ANYEVENT_VERBOSE> |
2078 | =item C<PERL_ANYEVENT_VERBOSE> |
1958 | |
2079 | |
1959 | By default, AnyEvent will be completely silent except in fatal |
2080 | By default, AnyEvent will only log messages with loglevel C<3> |
1960 | conditions. You can set this environment variable to make AnyEvent more |
2081 | (C<critical>) or higher (see L<AnyEvent::Log>). You can set this |
|
|
2082 | environment variable to a numerical loglevel to make AnyEvent more (or |
1961 | talkative. |
2083 | less) talkative. |
1962 | |
2084 | |
|
|
2085 | If you want to do more than just set the global logging level |
|
|
2086 | you should have a look at C<PERL_ANYEVENT_LOG>, which allows much more |
|
|
2087 | complex specifications. |
|
|
2088 | |
|
|
2089 | When set to C<0> (C<off>), then no messages whatsoever will be logged with |
|
|
2090 | the default logging settings. |
|
|
2091 | |
1963 | When set to C<1> or higher, causes AnyEvent to warn about unexpected |
2092 | When set to C<5> or higher (C<warn>), causes AnyEvent to warn about |
1964 | conditions, such as not being able to load the event model specified by |
2093 | unexpected conditions, such as not being able to load the event model |
1965 | C<PERL_ANYEVENT_MODEL>. |
2094 | specified by C<PERL_ANYEVENT_MODEL>, or a guard callback throwing an |
|
|
2095 | exception - this is the minimum recommended level. |
1966 | |

1968 | model it chooses. |
2098 | chooses. |
1969 | |
2099 | |
1970 | When set to C<8> or higher, then AnyEvent will report extra information on |
2100 | When set to C<8> or higher (debug), then AnyEvent will report extra information on |
1971 | which optional modules it loads and how it implements certain features. |

|
|
2106 | all C<debug> messages of some module to stderr, warnings and above to |
|
|
2107 | stderr, and errors and above to syslog, with: |
