i using error function in quite few of functions , propagate error messages user. however, don't want include information where error occured exactly; information should go log files. for example, have class manages connection server. if connection times out, calls error("connection timed out!") the error message caught calling code via pcall . however, message contains not message passed, name of file caused error , line number: common/net/enetclient.lua:21: connection timed out! the question is: there way retrieve error message itself, or have manually following: local status, msg = pcall(somefunctionthatthrowserrors) if not status local file, msg = msg:match("(.-:%d+): (.+)") print("error: " .. msg) end cheers, from documentation of error function : error (message [, level]) terminates last protected function called , returns message error message. function error never returns. usually, error

firstly isn't duplicate of this question because i'm not behind load balancer @ moment. randomly restarting instance isn't satisfactory solution either. i moved our store using local mysql db on ec2 rds , we're getting errors on backend when they're moving categories around / adding products. sqlstate[hy000]: general error: 1205 lock wait timeout exceeded; try restarting transaction i've seen other variations of pdo errors. how 1 go eliminating these issues? i've read suggestions 'keep retrying' seems stupid. i've tried tinkering innodb_lock_wait_timeout , others doesn't seem resolve it. i have disabled magento logging db - see if helps going forward. unfortunately have wait while let staff tinker on backend , see if fix has effect. thanks update now seeing bunch of these user error: ddl statements not allowed in transactions

i have question. have array of alphabet. , every letter needs !$letter, needs echo out !b, !d, !f i'm unsure how this. i've been told use modulo, % this. but reading lot on internet , things haven't gotten clearer me. i appreciate can me on matter! in advance! foreach ($alphabet $i => $letter) { echo (($i % 2) == 1 ? '!' : '') . $letter; } $i position of letter in array; since array indexes start 0, letters have odd indexes. $i % 2 0 when $i even, 1 when it's odd. grade school arithmetic, should prerequisite programming career.

signals differ between implementation. there nice tables in apue (advanced programming in unix environment), such "figure 10.1 unix system signals" on page 292 of 2nd edition. so let's take exemplary sigwaiting . signals appear in documentation int , implementations seem use #define instead of const int . however, standard stipulate anywhere 1 can rely on signals being #define d? or can assume based on fact that, say, virtually every existing implementation uses #define . or bad assumption altogether? the rationale this: if can rely on #define being used, can use #ifdef hide more exotic signals implementations don't use it. const int constant names not aware of similar mechanism allow compile time decision made. see posix (2008, 2013) specification <signal.h> . in part, says: the <signal.h> header shall define following macros used refer signals occur in system. signals defined here begin letters sig followed uppercase letter.

in adobe air application hide initial window , create window loads in separate html file. possible call function in 1 window exists inside another? i have read examples such as: possible call javascript method in context of window? but i'm using native windows , not html windows don't think it'll work. any ideas? the structure like: `file1.html` function dosomething() { } so want call dosomething function inside file1 file2 `file2.html` dosomething();

as part of university work need understand linked list code have been given. having problems insert method-the part deals general case-as code below: //in general case, need chain down linked list //from head until find location new //list node. if reach end of list before finding //the specified location, know given index out //of range , throw exception. else { node nodepointer = listhead; int = 1; while (i < index) { nodepointer = nodepointer.next; += 1; if (nodepointer == null) { throw new sequencelistexception("indexed element out of range"); } } //now we've found node before position of //new one, 'hook in' new node. nodepointer.next = new node(o, nodepointer.next); the problem having can see method inserts node , makes point next node, node replaced. far can see there has been no change node replaced, meaning there 2 nodes pointing same next.

i have scenario message transformation in esb. want know message transformation mediator (xslt, enrich, payload factory) suitable , common each of these scenario? 1- changing data type of 1 or more field of message 2- deleting 1 or more field of message 3- adding 1 or more new field message 4- changing name of 1 or more field of message 5- changing order of message's fields thanks in advance. the xslt mediator provides lot of flexibility on transforming messages on other mediators. so, can using xslt mediator. see, can achieve scenarios 2-5 using payload mediator quite easily. i'm not sure meant in first scenario though.

in android app plot airports on google maps. when zoomed out far, density gets high. i'm familiar marker clustering libraries, rather have solution distribution of airports shown, leaving out overlapping ones, , when zoom in more airports filled in needed. tips on this. clustering need. you need to: position cluster @ same latlng 1 of markers in cluster use same icon cluster regular markers taking example android maps extensions, i'm familiar with, have modify code in clustermarker.java from private latlng calculateclusterposition() { latlngbounds.builder builder = latlngbounds.builder(); (delegatingmarker m : markers) { builder.include(m.getposition()); } return builder.build().getcenter(); } to like private latlng calculateclusterposition() { return markers.get(0).getposition(); } or bit more sophisticated algorithm, calculates center , iterates on markers again find nearest marker , use position.

i noobie trying figure why segue.identifier coming (null), before segue (prepareforsegue) , after segue (unwindtolist). doing wrong, or missing? i've set segue identifier correctly scenes involved (in segue attributes).
