[solved] The following PHP functions are missing

damienbuckley · 2014-01-16 06:26:03

I’m in the middle of migrating to a new server and although TXP appears to be working fine I’m getting the following list of missing functions:

The following PHP functions (which may be necessary to run Textpattern) are disabled on your server: apc_cache_info, apc_clear_cache, apc_sma_info, apc_store, apc_fetch, apc_delete, apc_delete_file, apc_define_constants, apc_load_constants, apc_compile_file, apc_add, apc_inc, apc_dec, apc_cas, apc_bin_dump, apc_bin_load, apc_bin_dumpfile, apc_bin_loadfile, apc_exists, eval, proc_close, proc_get_status, proc_nice, proc_terminate, , openlog, syslog, closelog, apache_child_terminate, apache_get_modules, apache_get_version, apache_getenv, apache_note, apache_request_headers, apache_reset_timeout, apache_note, apache_setenv, virtual, ini_alter, pcntl_alarm, pcntl_exec, pcntl_fork, pcntl_setpriority, posix_access, posix_kil, posix_mkfifo, posix_setegid, posix_seteuid, posix_setgid, posix_setpgid, posix_setsid, posix_setuid

From this FAQ entry it appears that the two definites I need are:

apache_get_modules
apache_get_version

I have a few in the not required list but also a fair few not listed at all. Following is an edited list – I’ve edited out the known required functions and the non-required functions leaving the missing functions not listed in the FAQ post:

apc_cache_info,
apc_clear_cache,
apc_sma_info,
apc_store,
apc_fetch,
apc_delete,
apc_delete_file,
apc_define_constants,
apc_load_constants,
apc_compile_file,
apc_add,
apc_inc,
apc_dec,
apc_cas,
apc_bin_dump,
apc_bin_load,
apc_bin_dumpfile,
apc_bin_loadfile,
apc_exists,
eval,
apache_request_headers,
apache_reset_timeout,
pcntl_alarm,
pcntl_exec,
pcntl_fork,
pcntl_setpriority,
posix_access,
posix_kil,
posix_mkfifo,
posix_setegid,
posix_seteuid,
posix_setgid,
posix_setpgid,
posix_setsid,
posix_setuid

Can anyone shed light on what I actually do / don’t need please?

You can safely ignore apc_* as they refer to the APC PHP cache.

Without eval, I guess you won’t be able to run <txp:php /> (try <txp:php>echo 'hi';</txp:php>), and some plugins could break too.

Thanks. Are there any others I need to worry about?

pcntl_
posix_ etc

I remembered wet posted something about pcntl_.

Awesome, thanks for that. Looks like the list is down to this pretty much:

apache_request_headers,
apache_reset_timeout,

posix_access,
posix_kil,
posix_mkfifo,
posix_setegid,
posix_seteuid,
posix_setgid,
posix_setpgid,
posix_setsid,
posix_setuid

Here you find some posix’ one doesn’t need.

For unusual patterns like “posix_” Google (i.e. the search field top right on all pages) isn’t the matter of choice. For this purpose the forum internal search (the search tab) is more reliable.

Thankyou. You’ve been hugely helpful.

Wow. I just saw that for the first time. Is that new with the redesign or have I been snow-blind for years?

Mustard-blind, and that is an excuse :))
I’m quite sure it has been there for years, though I admit I’ve not often taken notice of the tabs. The spot I remember better is the tiny link below the search field.

The forum search’s been kind of hidden and partly replaced because it didn’t work satisfactorily (can’t tell whether that’s better now), but I always prefer(red) it for searches that Google believes are mistyped.

Bravo, sir. +1 bonus point for that.

I’ll leave this thread now – apologies for hijacking it.

following list of missing functions

To shed some light on this, we don’t check whether functions are missing. The functions we list are explicitly disabled with a configuration directive set in PHP’s main configuration file. The list is raw and doesn’t really tell anything on its own.

eval

Without eval you can not use any plugins or PHP tags in your templates. Plugins and PHP blocks are evaluated with it.

apc_*, posix_*, pcntl_*

These are functions from optional PHP extensions. Your host disabling these seems counterproductive. If they have those extensions loaded, they should just unload them. You can’t anyways use them when their API access is disabled. Having rampant OPcode APC which you can’t flush is just mad.
