Re: [Discuss] mod_lua and database connectivity

Maybe you need this: https://github.com/zhaozg/mod_luaex

 Supporting luasql would be a big bonus, though I understand if goal is to
 provide a quick and dirty api which is backed by mod_dbd

 Connecting to a database:

 Hmm, if db here represents a handle, it should prolly be paired with
 acquire not open.

 print(Deleted  .. affected ..  rows!)
 end

 -- Run a query and get the rows returned:

 Check your errors :-)

 Also, be careful what you return, you don't want to the API to force you
 to realize all results from a query eagerly.


 if rows then
 r:puts(We got  .. #rows  ..  results!)
 for k, row in pairs(rows) do
 print(Name:  .. row[1] .. br/)
 end
 else
 r:puts(DB error:  .. err)
 end

 -- Run a prepared statement and inject values into it:
 local rows, err = db:inject(r, SELECT `name` FROM `tbl` WHERE `id` =
 %u, 1234)



 Hmm, I would expect an API like

 local pstmt, err = h:prepare(...)
 ... = pstmt:execute(hello, 7)
 -- or ... = pstmt:query(hello, 7)

 or such style api. Injecting into implicit prepared statement is a
 strange api.


 if rows then
 
 else
 
 end

 Miscellaneous:

 -- escaping strings for use in db queries:
 local escaped = db:escape(r, [[foobar'|baz]])


 So, any comments, suggestions, remarks, objections and so on is very
 much welcomed. If there are no big objections to implementing this
 feature, I will consider it as lazy consensus and commit the bindings to
 trunk sometime soon along with updated documentation.

 With regards,
 Daniel.

 PS: I _have_ checked and double checked the code properly this time, so
 it conforms to the style requirements and works with maintainer mode. I
 know I usually get something wrong, but this time I think it's as close
 to perfect as it can get :) (but then again, I always write something
 bad, so apologies in advance if you find a bug)

Re: Additional core functions for mod_lua

2012-08-07 Thread zhiguo zhao

  I write a mod_luaex[ https://github.com/zhaozg/mod_luaex ]  to extends
mod_lua, it support session, dbd, filter and other, so more flexible.  It
use apreq, lua-apr[ https://github.com/zhaozg/lua-apr ],and merge function
from  http://people.apache.org/~humbedooh/lua_ap/.


2012/8/6 Daniel Gruno rum...@cord.dk

 If no one objects, I'll start moving in some functions to the mod_lua
 core, starting with the ones that pertain to obtaining a static value
 from the request/server, as well as the flush and sendfile function, and
 making them part of the request_rec package. This includes the following
 (as they will appear when imported):

 r:flush() - Flushes the output buffer
 r:sendfile(filename) -  Sends a file using sendfile if available
 r.port -the port in use by the request
 r.banner -  the server banner
 r.options - the Options directive for the request
 r.allowoverrides -  the AllowOverride directive for the request
 r.started - the time the server was (re)started
 r.basic_auth_pw -   the basic auth password, if any was sent
 r.limit_req_body -  The current request body limit (or 0 for none)
 r.server_built -The time the server was built
 r.is_initial_req -  Whether this is the initial request or a subreq
 r.remaining -   The remaining bytes in the request body
 r.some_auth_required -  Whether some authorization is/was required
 r.server_name - The server name for the request
 r.auth_name -   The realm used (if any) for authorization

 This leaves the following functions still in the apache2 package -
 If you'd rather see any of them moved to the request_rec package, do say
 so - :

 apache2.base64_encode - Encode a string in base64
 apache2.base64_decode - Decode a base64 string
 apache2.md5 -   Generate an MD5 hash
 apache2.sha1 -  Generate a SHA-1 hash
 apache2.escape -URL-escape a string
 apache2.unescape -  unescape an URL-encoded string
 apache2.mpm_query - Query the MPM for information
 apache2.expr -  Evaluate an ap_expr string
 apache2.scoreboard_process -Query the process scoreboard
 apache2.scoreboard_worker - Query a worker scoreboard
 apache2.clock - Returns the current time in microseconds
 apache2.requestbody -   Fetches (or saves) the request body
 apache2.dbopen -Opens up a database connection
 (supports both apr_dbd and mod_dbd)
 apache2.add_input_filter -  Adds an input filter to the request
 apache2.module_info -   Queries the server for info about a mod
 apache2.loaded_modules -Lists all the loaded modules
 apache2.runtime_dir_relative -  Returns a path relative to runtime dir
 apache2.server_info -   Returns information about the executable
 apache2.set_document_root - Sets the document root for a request
 apache2.add_version_component - Adds a version component
 apache2.os_escape_path -Escapes a path as a URL
 apache2.strcmp_match -  Does a strcmp_match (the foo* kind)
 apache2.set_keepalive - Set the keepalive status for a request
 apache2.make_etag - Creates an entity tag
 apache2.send_interim_response - Sends an interim response (or does it?)
 apache2.custom_response -   Sets a custom response for an error msg
 apache2.exists_config_define -  Query whether a define was made
 apache2.state_query -   Queries the server for state info
 apache2.stat -  Stats a file and returns info as a table
 apache2.regex - Evaluates regular expressions
 apache2.sleep - Sleeps for N seconds (accepts floats)
 apache2.get_server_name_for_url Servername for URL purposes

 Full descriptions and examples are still available at
 http://people.apache.org/~humbedooh/lua_ap/ if you need more info.

 If anyone has any other requests for internal functions they'd like to
 use in mod_lua, just speak up, I'm always happy to include more
 functionality.

 With regards,
 Daniel.

Hi all,

   I found when I enable mod_session with cookie, everytime response have
tow times Set-Cookie.
  I found function session_cookie_save react to both headers_out and

 automatically generated mail from a Linux box which builds the NetWare

 I was today self suprised how nicely it works ... :-)
 Did setup the stuff a few days back right after I got it working when I
 commited the bunch of build system changes, and already forgot about (but
 the cronjob didnt forget to run ...)
 also sorry that I did not yet look into the issue closer since I was whole
 day busy with other stuff ...
 if nobody objetcs I would like to let the cronjob continue, and once a fix
 is commited the mails should stop again.

in http-dev, but the letter can be send to every's box with some reason.,

   And now I update mod_lua to support lua server scope with
apr_reslist_apis, and I do some test with ab on my Pc.
   I got better performance. (75 - 227 - 277)  #/s
   Change please see patch file, I hope this patch can be merge in svn..  :)

Description: Binary data

Fwd: patch to mod_lua(support server scope, better performance)

2011-03-10 Thread zhiguo zhao

Hi,

   Some days I post my first letter(
http://mail-archives.apache.org/mod_mbox/httpd-dev/201103.mbox/raw/%3CAANLkTimfg4yeGExZXNP=yjybjdrmhrqpb4jo--sn6...@mail.gmail.com%3E)
in http-dev, but the letter can be send to every's box with some reason.,

   And now I update mod_lua to support lua server scope with
apr_reslist_apis, and I do some test with ab on my Pc.
   I got better performance. (75 - 227 - 277)  #/s
   Change please see patch file, I hope this patch can be merge in svn..  :)

mod_lua in svn,head version
