[Logging] Review
by Phil Endecott 10 Feb '08

10 Feb '08

My review of the proposed logging library follows. Summary: I was disappointed by the amount of code needed to get the most basic logging working. The use of macros to declare loggers seems like a bad design choice. The absence of support for syslog was surprising. I encountered many compiler warnings. The documentation was unsatisfactory. Many of the features that I would have liked to see were missing. Despite all this, John seems to be enthusiastic and responsive: there is a real chance that he will be able to fix many of these problems. Detail: In order to evaluate the library I decided to apply it to Decimail, an IMAP mail server that I wrote. It currently does some fairly basic logging of the IMAP conversation, enabled by a flag in its configuration, to syslog. Most of the programs that I've written do some sort of logging. Typically it's something as simple as: #include <iostreams> cerr << "starting to frobnicate\n"; or #include <syslog.h> syslog(LOG_INFO,"starting to frobnicate"); or #include <assert.h> assert(frob!=-1); These techniques are all very simple to use, and I feel that a logging library needs to be equally straightforward for basic operations: #include <boost/logging.hpp> log << "starting to frobnicate"; Of course it needs to offer more features than that - but the most basic use needs to be simple. (If it's not that simple, then potential users will instead just write to cerr as above; as their needs slowly grow they'll add their own ad-hoc logging functions; it will then be too late to take the leap to a logging library.) So I started by reading the main_intro.html and getting_started.html docs. I eventually got to "Example 1", which described how I had to add two new files to my project (21 lines) and call an initialisation function from main(). I could then log by changing my code as follows: if (Configuration::singleton().get_bool("imapd_log_imap",false)) { //syslog(LOG_MAIL|LOG_DEBUG,"{%d} S: * %s",num,msg.c_str()); L_ << "{" << num << "} S: * " << msg; } Having fixed one error in the example (g_l_filter vs. g_log_filter) and copious warnings I was able to see log output on the console (twice?) and in a file. This was all a lot more effort than I was expecting, but it did seem to work. I found the use of macros in example 1 unsatisfactory. Specifically, the logger "object" which I declare in the header and to which I send my log messages (L_ in the code above) is actually a macro, not an object. This means that I have to handle it with great care. For example, say I currently have: void do_something(ostream& log_to, .......) { log_to << "starting to do something"; ... } and I want to convert this to use this library. I write: void do_something(logger& log_to, .......) { log_to << "starting to do something"; ... } This fails - and probably with an incomprehesible error message. The motivation for the macro is sensible: it evaluates to something like if (l.level > current_level) l so that time-consuming functions in the log line are not evaluated if they will not actually be stored. But I would much prefer to see this optimisation made more explicit, so that the user can tell what's going on and avoid it if they want or need to: logger l; l << "message"; // wasteful if logging is disabled, but do I care - foo(l); // - because this works as expected. LOG_IF_ENABLED(l) << expensive_function(); // if I do care, I can invoke a macro explicitly #define ll LOG_IF_ENABLED(l) // or if I want conciseness I can _choose_ to do this ll << expensive_function(); Or I could do this, without a macro at all, if I were the sort of person who felt that all macros were evil: if (l.enabled()) l << expensive_function(); I think that what's practically needed to make this work is to bundle together the current filter and logger objects into a single _object_, rather than bundling them together using a macro. Next I tried to use the library's "filter" mechanism in place of the if-condition you can see above. I looked at "Step 1: Filtering the message" at workflow.html, expecting to find a filter that I could initialise with my condition (as a value, or by reference to a variable, or passing a functor or function-pointer). But it seems that all of the provided filter classes are things to provide various sorts of thread-safety. Writing my own is not difficult, though it might be more conventional to use a functor (i.e. operator()()) rather than a class with an is_enabled member [this would allow you to use things like lambda expressions, I think]. So I wrote: struct log_imap_filter { bool is_enabled() const { return Configuration::singleton().get_bool("imapd_log_imap",false); } }; Using this involved more macros: // log.hh: typedef log_imap_filter filter_type; BOOST_DECLARE_LOG_FILTER(g_log_filter, filter_type) // log.cc: BOOST_DEFINE_LOG_FILTER(g_log_filter, filter_type ) I don't know why these need to be macros. It seems to obfuscate what is going on to me. The last thing that I needed to replace my syslog call was to specify the log level, which I noticed in workflow.html under "Step 2A: Gathering the message". (The fact that I couldn't find any description of this fairly central functionality anywhere else, e.g. in any of the pages in the tutorial section, seems typical of the documentation). Based on that example, I tried: L_(dbg) << "happily debugging"; which failed to compile. I haven't worked out what I should have written. I did try it with a namespace prefix. The final thing that I looked at in detail was scoped logging. When I'm writing more detailed logging code (e.g. for debugging) I generally make it scoped, i.e. reporting interesting function entries and normally exits. I like to indent each scope by a few characters in the log output, e.g. void foo() { cerr << "foo starting\n"; for(int i=0; i<5; ++i) { blah(i); } cerr << "foo done.\n"; } void blah(int i) { cerr << " blah " << i << "\n"; // note indentation ... } I read the scoped_logs.html page, and it seems that the BOOST_SCOPED_LOG[_CTX] macro deals with the starting/ending business. Compared to my explicit start/done output above, it has the feature that the done message will be generated if the function returns using an explicit return statement or if it throws an exception. This may be an advantage or a disadvantage: with my code, the absence of the done message would suggest that an exception might have occurred. Ideally the end-of-scope log message would indicate whether it was invoked during exception handling; could that be done using compiler-magic? But why does it have to be a macro? And there doesn't seem to be any indentation or other way of matching up the start and end messages. If they were matched up, then a log file viewer tool could provide collapse/expand tree view functionality (does Purify still do something like that?). I was also surprised that no use was made of __LINE__, __FUNCTION__ etc. in the scoped logging or other macros. I also don't see any way to couple the scoped logging features with enabling and disabling logging. Specifically, I might detect that something of interest is happening and want to increase the log level within that scope: void foo() { scoped_log sl(log); for (int i=0; i<100; ++i) { scoped_enabled_logging_if s(log, i==42); blah(i); // logging enabled in here only if i is 42 } } I didn't look in much detail at the "destinations" functionality, but I'd like to note some of the features that syslog offers for files that it writes to: - Flushing of files after each message is optional. Not flushing helps performance, but it might mean that critical messages are lost before a crash. - Enormous numbers of identical messages within a short period are compressed to a single line, "last message repeated 193247 times". - Periodic "MARK" lines can be generated to show that the application is still running. Other features that I've seen in applications that do their own logging to files include: - Creating new files for each sub-process or thread, by appending a thread identifier to the filename. - Truncating individual messages to some limit (e.g. to avoid logging a rogue char* that points to a huge block of stuff with a \0 a megabyte later), or individual fields within the log message. In my quick review I didn't see any of that functionality. The rolling_file feature looks useful for long-running applications where it's necessary to move the log files (e.g. to compress them) without interrupting the process. I suggest referring to the logrotate utility for how this sort of thing is often handled on Unix servers; for example, it can be configured to send a signal to a process to tell it to close and re-open its log file with the same filename. Finally I'd like to look at how the user can control the logging. I don't see any built-in functionality for this. I have a couple of suggestions: environment variables and command-line options. An environment variable could be used as follows. The code would do something like this: g_l()->writer().write(::getenv("MYAPP_LOG_FMT"), ::getenv("MYAPP_LOG_DEST")); The programmer's choice of format and destination may or may not override the user's choice via the variables. The user could then control the format and destination when invoking the program: $ export MYAPP_LOG_FMT='%time%($hh:$mm.$ss.$mili) [%idx%] |\n' $ export MYAPP_LOG_DEST='file(debug.log)' $ myapp Firefox has something a bit like that IIRC. For command-line integration, I suggest providing an initialisation function that processes argc and argv looking for debug options, and strips them: int main(int argc, char* argv[]) { log.init(argc,argv); // modifies argc and argc // following code doesn't see debug options ... } DirectFB has something like that. Again you could use this to define formats and destinations. You could also give the user control over scoped filtering via a command-line interface. For example: $ myapp --log:default=none --log:parser=debug --log:scheduler=info The names 'parser' and 'scheduler' would match scoped log-enable blocks. I could imagine hierarchical names too. I've used one commercial C++ application that has this sort of logging (you can indicate component, log level and destination), and it proved useful. Conclusion: * What is your evaluation of the design? Breaks up the problem into a sensible set of components. Basic usage requires too much effort. Lacks many features that I would find useful. Pervasive use of macros is unappealing. * What is your evaluation of the implementation? Seems to work. Many compiler warnings do not inspire confidence in code quality. Have not reviewed the code in any detail. * What is your evaluation of the documentation? Poor. But in part, that's because it is documenting the considerable effort required to get basic functionality working. * What is your evaluation of the potential usefulness of the library? Everyone needs logging. If they do it using this library, they'll have to write a lot of code themselves to implement their own filters, destinations and so on. In practice they won't bother and will write their own ad-hoc code. * Did you try to use the library? With what compiler? Did you have any problems? Yes, with gcc-4.1 on Linux. I encountered various warnings which John has already resolved. * How much effort did you put into your evaluation? About 6 hours. * Are you knowledgeable about the problem domain? I've written and used numerous programs with logging features, but have never attempted to write a logging library. And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? No, not in its current form. Phil.

by Bruce Sharpe 10 Feb '08

I am a user of many Boost libraries and far from a C++ guru, so my comments are from that perspective. * What is your evaluation of the design? It is very flexible, it is easy to modify one's usage of it and not too hard to use. It has been very useful for me. * What is your evaluation of the implementation? It generates some compiler warnings that should be eliminated. Other than that, I have not run into any serious issues. * What is your evaluation of the documentation? It is quite thorough. It takes a little more digging than ideal to get started right out of the box. That is just a question of organization, all the necessary content seems to be there. * What is your evaluation of the potential usefulness of the library? I needed exactly this functionality, which is quite fundamental to many kinds of application development. I looked first to Boost for a library and was somewhat surprised not to find one. I was very glad to be able to be able to use the pre-Boost version. * Did you try to use the library? With what compiler? Did you have any problems? I have used both v1 and v2 of the library with Visual C++ Express 2005 on Windows and gcc 4.0.1 on OS X. Other than the compiler warnings mentioned above, no problems. * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? I would describe myself as a light user of the library. I have used it for a single logger with multiple levels and multiple destinations, probably a very common use case. * Are you knowledgeable about the problem domain? No, other than knowing roughly what I wanted. My logging in the past has been done via home-grown ad hoc techniques. * Do you think the library should be accepted as a Boost library? Yes.

Thank you to everybody who responded to my post. I used the solution sugested by several people who said I should use control objects, with the function wait. I posted the final version of my code. The purpose of the project is to create a thread manager which will let threads execute based upon the priority of that thread: http://acumenconsultinginc.net/TechNotes/cpp/PriorityThreadQueue/index.html --------------------------------- Looking for last minute shopping deals?

[serialization][graph] Links to the getting started documentation
by Daniel James 09 Feb '08

09 Feb '08

Hi, Both serialization and graph documentation contains links to sections of the old getting started documentation which was rewritten a while ago, so now they just end up at the getting started introduction. The attached patches try to change the links to somewhere more useful. In the graph documentation, I changed the 'Boost Jam Build Instructions' link to point to the instructions in boost build, as getting started doesn't seem to have a single location to point to. Is it okay to commit them (for trunk and release)? Daniel

Fixing links broken by migration to new site
by Daniel James 09 Feb '08

09 Feb '08

Hello all, I've fixed a load of links in the fix-links branch. You can see the changesets at: http://svn.boost.org/trac/boost/changeset/43168 (fixes people links) http://svn.boost.org/trac/boost/changeset/43169 (fixes links under the 'more' directory) http://svn.boost.org/trac/boost/changeset/43180 (a couple of links I missed) These changes are a fairly simple search and replace. If no one has any objections I'm just going to apply them to trunk tomorrow without getting individual authors' permissions. There are also some other, less mechanical, changes on that branch, unrelated to the new website. I'll ask library authors to review them before I merge them. Daniel

[Boost.math] Jamfile option not valid for intel-darwin platform

Hi, Both these Jamfiles boost/libs/math/test/Jamfile.v2 boost/libs/math/example/Jamfile/v2 contain this line <toolset>intel:<cxxflags>-Qwd264,239 which is, unfortunately, not recognized by the Intel compilers on darwin.

Hmmm, that /nologo option looks like a Windows specific option as well. Here's the man page for -Q for Intel on darwin. Component Control This section describes component control options. You can direct the compiler to specify alternate tools for preprocessing, compilation, assembly, and linking. Further, you can invoke options specific to your alternate tools on the command line. These are the component con- trol options. -Qinstall <dir> Set <dir> as the root of the compiler installation. -Qlocation,<tool>,<path> Set <path> as the location of the tool specified by <tool>. <tool> may be cpp, c, asm, or ld. <path> is the complete path to the tool. For example: -Qlocation,gas,<path> Specifies the GNU assembler. -Qlocation,gld,<path> Specifies the GNU linker. -Qoption,<tool>,<optlist> Pass options <optlist> to the tool specified by <tool>. <tool> may be cpp, c, asm, or ld. The <optlist> argument indicates one or more valid argument strings for the designated program. If the argument is a command-line option, you must include the hyphen. If the argument contains a space or tab character, you must enclose the entire argument in quotation characters (""). You must separate multiple arguments with commas. -- Noel

[unordered] memory questions
by Michael Marcin 08 Feb '08

08 Feb '08

I'm on a platform where no memory can be dynamically allocated before main and all dynamically allocated memory must be released before main returns. Is there a way to ensure this behavior with boost's unordered containers if they have static duration? I.e. does the default constructor allocate memory and does clear or default construct + swap release all memory? Thanks, Michael Marcin

[Logging] Support for syslog ?
by Phil Endecott 08 Feb '08

08 Feb '08

Dear All, I've decided to port one of my apps to the proposed logging library so that I can write a review. A couple of issues have come up immediately: - This program currently logs using syslog. I was expecting to find a back-end for this logging library for syslog, since it is the standard logging mechanism on POSIX. But I can't see anything. Am I missing something, or is it really not there? - I spent a while trying to work out how to compile the library. I have now come to the conclusion that it is header-only, and that it's only the tests and the examples (called "scenarios") that you might want to compile by following the instructions in the documentation. Is this right? From what I can see so far, using this library is not going to be a compelling alternative to the concise #include <syslog.h> syslog(LOG_WARN,"Blob %d failed to %s",n,x); Cheers, Phil.

Exception handler of RHEL4 isn't working after the integration of Serialization code !!!
by Arunava Saha 08 Feb '08

08 Feb '08

Hi experts, After the integration of boost serialization code, the exception handler of RHEL4 isn't working at all. Do anyone of you encountered this? Or can you point to any potential mistake for which this can happen? This is quite urgent. Thanks, Arunava.

A grep like boost::iostreams filter.
by Emre Turkay 08 Feb '08

08 Feb '08

Hi folks, I tried to use the regex_filter for grep like functionality, but I think it doesn't work like that. So, here goes a grep_filter and a driver main() function as an example. It is an input filter which returns only the matching lines of the given regex. I think it can be used by others, too. Is it possible to put this class into distribution, as an example maybe? Thanks, Emre Türkay

[flyweight] Review period extended to February 3
by Ion Gaztañaga 07 Feb '08

07 Feb '08

Hi to all, We've received 4 positive reviews and several comments, but we still want more ;-) Some people expressed interested in the pre-review period and I want to give some time (weekend is the right time to review a Boost library...) to those who are interested in the library and have not found time to review it. The last review day is February 3. Common, the library is very lightweight ;-) to review, it's pretty well documented, it's certainly small and very general purpose. Here is the information. Last call to passengers! *Description:* Flyweights are small-sized handle classes granting constant access to shared common data, thus allowing for the management of large amounts of entities within reasonable memory limits. Boost.Flyweight makes it easy to use this common programming idiom by providing the class template flyweight<T>, which acts as a drop-in replacement for const T. *Online docs:* http://tinyurl.com/2sstyr http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/index.html *Download:* http://tinyurl.com/hrdm6 http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directo… *Notes:* 1) We've seen some suggestions in the mailing list for Flyweight. Joaquín has nicely explained a couple of issues that we'd like to address/discuss in the review: http://tinyurl.com/33ghtf http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/doc/review_… 2) Flyweight needs Boost 1.35 elements because the library depends on libraries like Interprocess for some features/tests. Since SVN snapshot tarballs seem to be missing these days, those who want to try flyweight can download a working SVN-HEAD snapshot here: http://igaztanaga.drivehq.com/boost_trunk.tar.bz2 3) Serialization tests won't work. This feature is expected to work when some new features (discussed in the mailing list between Joaquín and Robert Ramey) are added in Boost.Serialization. Those are expected for Boost 1.36. What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * What is your evaluation of the design? * What is your evaluation of the implementation? * What is your evaluation of the documentation? * What is your evaluation of the potential usefulness of the library? * Did you try to use the library? With what compiler? Did you have any problems? * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? * Are you knowledgeable about the problem domain? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Ion Gaztañaga - Review Manager -

[xpressive] how to avoid running into stack overflow so easily
by Thorsten Ottosen 07 Feb '08

07 Feb '08

Hi Eric, (Apologies in advance for such a stupid question.) I'm building a fairly simple parser using xpressive. I need to parse text like this: node C91967 { label = "What brand of coffee do you use?"; position = (100 280); states = ("Columbian blend" "Columbian gold" "Columbian all star" "Columbian cinnamon"); HR_Inaccuracy = "0"; HR_Risk = "0"; HR_Time = "1"; HR_RefKey = ""; HR_Desc = "Question"; HR_ID = "91967"; HR_Def = "<div align=\"left\">&#160;</div><br/>"; HR_Web_Page = ""; HR_Type2 = "3"; } potential (C91976 | CXXX) { data = ( 0 1 % Coffee type not to your taste 0 1 % Discount coffee 0.98 0.02 % Low quality coffee filter 0 1 % Low water quality 0 1 % Old coffee machine 0 1 % Used coffee filter 0 1 % Water coffee mixture incorrect 0 1 ); % Other Problem } There are multiple nodes or potential in the files, so my final regex looks something like netFile = modelConfiguration >> causeNode >> actions >> optional( questions ) >> causeProbabilities >> actionProbabilities; I then make one regex to parse a single potential, and wrap that regex in another so I can look for a list of those potentials: sregex row = *space >> _float[push_back(ref(actionProbs),as<Float>(_))] >> space >> -*_ >> _ln; actionPotential = -*_ >> "potential (C" >> -*_ >> "data = (" >> +row >> -*_ >> '}'; actionProbabilities = +( *space >> actionPotential ); Now my problem is that I get a stack overflow very easily if the 'row' regex is too long. In factm I have to remove the latter ">> space" from 'row' to not get a stack overflow. Am I using the library in a fundamentally wrong way? If so, how can I try to fix it? best regards -Thorsten

Martin, Where you and I live, the nearest we get is exceptions for "research or private study" and "criticism or review", which I don't think apply in this case.

[1.35.0] Release branch snapshots
by Beman Dawes 07 Feb '08

07 Feb '08

The first attempt at a release branch snapshot is now available. See http://beta.boost.org/development/testing.html#Snapshots for more information, and a link to the actual files. Thanks to Martin Wille for setting up the hosting! The plan is to automatically build Unix and Windows snapshots on a daily basis. Right now the only snapshot available is a .zip with Windows line endings. For the moment the focus is simply getting the build process in place for both Unix and Windows. Once that is running more or less smoothly, the focus can shift to making sure the content is all there, and that other QA checks are being met. --Beman

[result_of] vs function name
by shunsuke 07 Feb '08

07 Feb '08

Hi, function name is not object. So, I don't know whether function name is lvalue or rvalue. For example, void foo() {} result_of<T_a_func_obj(???)>::type r = a_func_obj(foo); What should ??? be? Regards, -- Shunsuke Sogame

stdcxx-tests on release branch?
by John Maddock 07 Feb '08

07 Feb '08

Without wanting to be too pedantic (!), do we have a policy about which toolsets are tested on the release branch? I'm asking because we currently have a large number of failures for the "stdcxx" (Apache std lib) tests. Whilst we certainly should be testing this on the trunk going forward, it's not previously been a required release platform, hence the large number of failures. There are also one set of results (for msvc-8.0-stdcxx-4.2.1) that appear to failing almost everything and isn't even compiling the "hello world" config_info program: http://beta.boost.org/development/tests/release/developer/output/msvc-8-0-s… IMO this failure is made worse because the toolset used is simply called "msvc-8.0" so it shows up as a *required* platform, rather than a currently-unsupported one. Likewise the Sunpro and gcc tests with the apache std lib are simply called "gcc-4.2.1" and "sun". Apologies to the test runner for the gripe: we really do need you and appreciate the effort! It's just that we also need to be able to clearly focus on what is and is not required for *this next release*. Thanks, John.

[numeric/conversion] Quickbook changeover
by Daniel James 07 Feb '08

07 Feb '08

Hi, The numeric/conversion library seems to be in the middle of having it's documentation converted to quickbook and currently has both versions in the trunk and release branches. So we need to delete one of them in the release branch (and preferably in trunk as well). Is the quickbook based documentation ready for release? Daniel

[1.35.0] Inspection report on release snapshot now available
by Beman Dawes 07 Feb '08

07 Feb '08

An inspection report will now be run on the daily release snapshot. See http://beta.boost.org/development/testing.html#Snapshots for the link. There are far too many errors. We need to start a major effort to clean these up. One of the most common errors are broken links caused by the removal of people pages from the boost tree. Perhaps someone could write a script to replace all of these with a link to the web site, where the people pages still exist. Any volunteers? Reminder to developers: you have to fix the problem in the trunk, and then merge the fixes into branches/release. --Beman
