I wasn't happy leaving this is as is so I did some more testing.
I looked in /home/weewx/bin/user/belchertown.py for any mention of the 4
include files it uses to add content - nothing there.
So, I looked in /home/weewx/skins/Belchertown/index.html.templ and found 4
lines that reference the include files - they are of the form:
#if os.path.exists("index_hook_after_station_info.inc")
<!-- Start of index_hook_after_station_info row -->
<div class="row index-hook-after-station-info
border-bottom">
#include "index_hook_after_station_info.inc"
</div>
<!-- End of index_hook_after_station_info row -->
#end if
That caused me to look up the Cheetah '#include' directive:
"7.6 #include
Syntax:
#include [raw] FILENAME_EXPR #include [raw] source=STRING_EXPR
The #include directive is used to include text from outside the template
definition. The text can come from an external file or from
a $placeholder variable. When working with external files, Cheetah will
monitor for changes to the included file and update as necessary.
This example demonstrates its use with external files:
#include "includeFileName.txt"
The content of "includeFileName.txt" will be parsed for Cheetah syntax.
And this example demonstrates use with $placeholder variables:
#include source=$myParseText
The value of $myParseText will be parsed for Cheetah syntax. This is not
the same as simply placing the $placeholder tag ``$myParseText'' in the
template definition. In the latter case, the value of $myParseText would
not be parsed.
By default, included text will be parsed for Cheetah tags. The argument
``raw'' can be used to suppress the parsing.
#include raw "includeFileName.txt" #include raw source=$myParseText
Cheetah wraps each chunk of #include text inside a nested Template object.
Each nested template has a copy of the main template's searchList.
However, #set variables are visible across includes only if the defined
using the #set global keyword.
All directives must be balanced in the include file. That is, if you start
a #for or #if block inside the include, you must end it in the same
include. (This is unlike PHP, which allows unbalanced constructs in include
files.)"
I decided to insert the 'raw' argument into the 4 '#include' directives to
see if anything changed.
After about 1 hour. memory usage did not grow above about 65 MB!
I just removed the 'raw' argument and restarted WeeWX. After just a few
minutes, memory usage is almost 300 MB and growing!
As before, the station website is at:
https://lockyer.ca/weather/OsoyoosLakeNorthEast and the mem graphs are at
https://lockyer.ca/weather/OsoyoosLakeNorthEast/mem.
So, I think I have conclusively shown that the problem is within Cheetah
and is related to it parsing an include file.
I'm going to re-insert the 'raw' arguments and carry on.
Should I report this issue to the Cheetah folks or is there someone closer
to the Cheetah developers that can better do that?
Regards,
Garry
