Now as I look at it again I realized that the config check boxes had a bug. I fixed that 
and now the disable should work correctly.

This feature was asked by some people who monitor an experiment and have the browser window 
in the background, also have sound off (large office). So desktop notifications are a good 
thing for them.

> This feature was asked by some people ...

"show notifications" popups are strongly associated with disreputable web sites (presumably to 
push spam), it was surprising to see it from midas.

I agree. But unlike emails (where you get lots of spam as well), you can nicely blacklist/whitelist 
desktop notifications. I suppress all of them except the one for MIDAS. This allows me to watch our 
experiment without staring on the web page all the time.

The main question here is maybe if the desktop notification should be on or off by default (for a 
fresh browser). While you always can change that via the mhttpd "Config" page, the default value is 
chosen by the system. I thought I put it to "on" so people can experience it, and then turn it off if 
they don't like. Having them off by default, most people never would notice this possibility. But I'm 
open to a discussion here.

I updated the links on the midas wiki to the doxygen-generated documentation for MIDAS that you 
get after running "git clone midas; cd midas; make dox; firefox html/index.html".

Correct link is:
https://daq.triumf.ca/~daqweb/doc/midas-devel/html/

This takes you to a daily/nightly generated snapshot of the midas develop branch and the 
generated documentation with full call graphs.

Previous links were deficient is different ways:
- referred to http://ladd00 instead of https://daq
- referred to wrong path ~daqweb/doc/midas instead of ~daqweb/doc/midas-devel
- referred to the obsolete doxygen generator in midas/doc/html instead of midas/html.

If wrong links are still present on the midas wiki, please let us know and we will fix them.

The midas wiki at https://midas.triumf.ca was updated to mediawiki 1.22.4 - the latest production version. 
If you see any problems, please report them to this elog. K.O.

midas wiki at https://midas.triumf.ca/MidasWiki/index.php/Main_Page
was updated to MediaWiki version 1.27.1, the current MediaWiki LTS release.
Everything should work as before, but if you see any problems or anomalies, please report
them on this forum here.
K.O.

the midas wiki was updated to the latest LTS point release 1.27.5.

Also, an installation error was fixed that prevented confirmation of new accounts (git checkout 
REL1_28 instead of REL1_27, resulting in a version mismatch).

Support for MediaWiki LTS release 1.27 ends this Summer.

Next LTS release series is 1.31, see https://en.wikipedia.org/wiki/MediaWiki_version_history

This version requires php version 7 or newer which comes standard with ubuntu LTS 18.04 
and el8 (RHEL8), but not with el6 (SL6) and el7 (CentOS-7).

I guess we shall start planning this upgrade and the move of the wiki to a new host machine.

K.O.

the midas wiki was updated to the latest LTS point release 1.27.7, the latest (last?) security update.

mediawiki series 1.27 is now officially EOL, see
https://lists.wikimedia.org/pipermail/mediawiki-announce/2019-June/000231.html

they recommend that all users upgrade to the current LTS series 1.31.

for us it means moving the wiki from the present el6 (SL6) computer to
a more up-to-date platform (el8 or ubuntu LTS 18.04).

K.O.

The midas wiki at https://midas.triumf.ca has been upgraded to mediawiki version 1.25.2 (current 
production version). If you see any problems, please report them on this forum. K.O.

the midas release 2019-03 is ready for general use.

main changes from previous releases (midas-2017-10, midas-2018-12 and midas-2019-02):

- change to the midas URL scheme
- removal of cm_watchdog()
- rewrite of event buffer code (and fix of hard to trigger event buffer corruption bug)
- fully thread safe odb and event buffer code (except for rpc_send_event())
- corrected compatibility problems wrt older versions of midas when serving custom web pages via odb /custom/path

To obtain this release, either checkout the top of branch feature/midas-2019-03 (recommended)
or checkout the tag midas-2019-03-f.

A bug fix update for midas-2019-03:

- fix broken expand_env() in mhttpd
- fix "Invalid name passed to db_create_key: should not be an empty string" in midas.log when loading the MIDAS status page if one of the alarms has empty 
class name.

odbedit "ver" should report: Thu Jun 6 18:02:14 2019 -0700 - midas-2019-03-h on branch feature/midas-2019-03

K.O.

We are happy to the midas release "midas-2019-06" with the build system implemented in cmake and the midas, mxml and mscb 
projects switched to C++.

Changes since midas-2019-03:

minor bug fixes
switch of midas build to c++ with c++ linkage (no "extern C")
switch of midas build to cmake
removal of $(OS_DIR) from the midas library and bin paths (use $MIDASSYS/lib instead of $MIDASSYS/linux/lib)
mxml and mscb are implemented as git submodules

Please review the following guide to update midas from previous release midas-2019-03 or older.

Update the code:

git checkout develop
git pull
git checkout feature/midas-2019-06
git pull
git submodule update --init # this will checkout correct versions of mxml and mscb
make clean
make cclean
rm -rf linux/bin
rm -rf linux/lib
rmdir linux
make cmake3 # or "make cmake" on ubuntu and macos
ls -l bin/odbedit bin/mlogger

Update experiment environment:

- change PATH from $MIDASSYS/linux/bin to $MIDASSYS/bin

Cleanup unneeded stuff:

- remove $HOME/packages/mxml (new location $MIDASSYS/mxml)
- remove $HOME/packages/mscb (new location $MIDASSYS/mscb)

Update experiment frontend build:

- change Makefile to remove $(OS_DIR) from library search path ($MIDASSYS/linux/lib becomes $MIDASSYS/lib)
- change Makefile to set mxml include path from $MIDASSYS/../mxml to $MIDASSYS/mxml (to avoid including the wrong 
version of mxml/strlcpy.h)
- update frontend code to use mfe.h and build as C++, see https://midas.triumf.ca/elog/Midas/1526

K.O.

Please note that 

"make cmake" / "make cmake3"

is an abbreviation for the "normal" cmake command chain. Users familiar with cmake can also do the standard command chain:

mkdir build
cd build
cmake ..
make
make install

I created the release branch for midas-2019-09 and tag midas-2019-09-a.

Since the previous release midas-2019-06, some news:

- new history graphics (Stefan)
- c++ frontend framework mvodb.h and tmfe.h merged from ALPHA-g (K.O.)
- we think we have all the fallout from switching to cmake and to c++11 sorted out

There is a number of known problems with the current code, see the bitbucket bug tracker:
https://bitbucket.org/tmidas/midas/issues?status=new&status=open

Hopefully we can use this release as a baseline for more testing and with luck we will
fix all the pending bugs and add all the pending missing code (the new sequencer web pages,
the "m" analyzer, etc) quickly and our next release midas-2019-10 will be the best midas ever.

To obtain this release, either checkout the top of branch feature/midas-2019-09 (recommended)
or checkout the tag midas-2019-09-a.

If you are using the last pre-cmake/c++ release midas-2019-03, I recommend that you stay with it
until our next release midas-2019-10.

midas-2020-03-a is here.

Accumulated changes and bug fixes since last tag midas-2019-09-i.

After this release, expect some instability on the develop branch as I commit the update of mhttpd to mongoose web server library 
version 6.16. More on that later.

To obtain this release, either checkout the top of branch release/midas-2020-03 (recommended)
or checkout the tag midas-2020-03-a.

Since the release of midas-2020-03, we are in a cycle of rapid development of midas,
with many changes made daily.

For production use, unless you rely on latest changes and/or bug fixes, please use the midas-2020-03 release branch.

Some of the recent changes broke compatibility with ROOTANA.

The current ROOTANA release 2020-03 is meant to work with and is compatible with midas-2020-03. Going forward
we will try to keep releases of midas and rootana in "lock step".
