revlog: seek to end of file before writing (issue4943)
Revlogs were recently refactored to open file handles in "a+" and use a
persistent file handle for reading and writing. This drastically
reduced the number of file handles being opened.
Unfortunately, it appears that some versions of Solaris lose the file
offset when performing a write after the handle has been seeked.
The simplest workaround is to seek to EOF on files opened in a+ mode
before writing to them, which is what this patch does.
Ideally, this code would exist in the vfs layer. However, this would
require creating a proxy class for file objects in order to provide a
custom implementation of write(). This would add overhead. Since
revlogs are the only files we open in a+ mode, the one-off workaround
in revlog.py should be sufficient.
This patch appears to have little to no impact on performance on my
Linux machine.

This tests if hgweb and hgwebdir still work if the REQUEST_URI variable is no longer passed with the request. Instead, SCRIPT_NAME and PATH_INFO should be used from d74fc8dec2b4 onward to route the request. $ hg init repo $ cd repo $ echo foo > bar $ hg add bar $ hg commit -m "test" $ hg tip changeset: 0:61c9426e69fe tag: tip user: test date: Thu Jan 01 00:00:00 1970 +0000 summary: test $ cat > request.py <<EOF > from mercurial.hgweb import hgweb, hgwebdir > from StringIO import StringIO > import os, sys > > errors = StringIO() > input = StringIO() > > def startrsp(status, headers): > print '---- STATUS' > print status > print '---- HEADERS' > print [i for i in headers if i[0] != 'ETag'] > print '---- DATA' > return output.write > > env = { > 'wsgi.version': (1, 0), > 'wsgi.url_scheme': 'http', > 'wsgi.errors': errors, > 'wsgi.input': input, > 'wsgi.multithread': False, > 'wsgi.multiprocess': False, > 'wsgi.run_once': False, > 'REQUEST_METHOD': 'GET', > 'SCRIPT_NAME': '', > 'SERVER_NAME': '127.0.0.1', > 'SERVER_PORT': os.environ['HGPORT'], > 'SERVER_PROTOCOL': 'HTTP/1.0' > } > > def process(app): > content = app(env, startrsp) > sys.stdout.write(output.getvalue()) > sys.stdout.write(''.join(content)) > getattr(content, 'close', lambda : None)() > print '---- ERRORS' > print errors.getvalue() > > output = StringIO() > env['PATH_INFO'] = '/' > env['QUERY_STRING'] = 'style=atom' > process(hgweb('.', name = 'repo')) > > output = StringIO() > env['PATH_INFO'] = '/file/tip/' > env['QUERY_STRING'] = 'style=raw' > process(hgweb('.', name = 'repo')) > > output = StringIO() > env['PATH_INFO'] = '/' > env['QUERY_STRING'] = 'style=raw' > process(hgwebdir({'repo': '.'})) > > output = StringIO() > env['PATH_INFO'] = '/repo/file/tip/' > env['QUERY_STRING'] = 'style=raw' > process(hgwebdir({'repo': '.'})) > EOF $ python request.py ---- STATUS 200 Script output follows ---- HEADERS [('Content-Type', 'application/atom+xml; charset=ascii')] ---- DATA <?xml version="1.0" encoding="ascii"?> <feed xmlns="http://www.w3.org/2005/Atom"> <!-- Changelog --> <id>http://127.0.0.1:$HGPORT/</id> <link rel="self" href="http://127.0.0.1:$HGPORT/atom-log"/> <link rel="alternate" href="http://127.0.0.1:$HGPORT/"/> <title>repo Changelog</title> <updated>1970-01-01T00:00:00+00:00</updated> <entry> <title>[default] test</title> <id>http://127.0.0.1:$HGPORT/#changeset-61c9426e69fef294feed5e2bbfc97d39944a5b1c</id> <link href="http://127.0.0.1:$HGPORT/rev/61c9426e69fe"/> <author> <name>test</name> <email>test</email> </author> <updated>1970-01-01T00:00:00+00:00</updated> <published>1970-01-01T00:00:00+00:00</published> <content type="xhtml"> <table xmlns="http://www.w3.org/1999/xhtml"> <tr> <th style="text-align:left;">changeset</th> <td>61c9426e69fe</td> </tr> <tr> <th style="text-align:left;">branch</th> <td>default</td> </tr> <tr> <th style="text-align:left;">bookmark</th> <td></td> </tr> <tr> <th style="text-align:left;">tag</th> <td>tip</td> </tr> <tr> <th style="text-align:left;">user</th> <td>test</td> </tr> <tr> <th style="text-align:left;vertical-align:top;">description</th> <td>test</td> </tr> <tr> <th style="text-align:left;vertical-align:top;">files</th> <td>bar<br /></td> </tr> </table> </content> </entry> </feed> ---- ERRORS ---- STATUS 200 Script output follows ---- HEADERS [('Content-Type', 'text/plain; charset=ascii')] ---- DATA -rw-r--r-- 4 bar ---- ERRORS ---- STATUS 200 Script output follows ---- HEADERS [('Content-Type', 'text/plain; charset=ascii')] ---- DATA /repo/ ---- ERRORS ---- STATUS 200 Script output follows ---- HEADERS [('Content-Type', 'text/plain; charset=ascii')] ---- DATA -rw-r--r-- 4 bar ---- ERRORS $ cd ..
